Langwith Mill, Nether Langwith, Nottinghamshire – July 2017
The 4th and final stop on Mookster and my July Northern Road Trip. Nestled almost in a sort of Farm Yard in Nottinghamshire; next to a disused Restaurant (Goff's Restaurant); a rather odd place for an eatery in a very rural location. Access did involve a bit of grazing field to get up to the mill.
The disused mill is a four storey Cotton Mill which was constructed in 1786. The mill was originally sixteen windows wide, which would have made Langwith one of the largest mills in the district. Cotton spinning at Langwith Mill ceased around 1848 and the place was converted into a Corn Mill in 1886. Langwith was still operating after WWII. The Mill was built in limestone with a slate roof which is now holed and in poor condition. Langwith was powered by a large water wheel fed from a dam nearby which is now a meadow.
The site is a curtilage building to the Grade II listed Langwith Mill House and a building of Local Interest in its own right. The listing was applied in 1985 as the mill is a site of Local Historical Interest.
It’s in pretty poor condition in places!
E.P. Bray, Chisworth Dye Works, Glossop – July 2017
So during a fairly unsuccessful road trip of a 20:4 fail ration on a huge 650 mile round trip, Northern Road Trip, Mookster and I arrived here. Nestled next to a public footpath; access was pretty easy, and although stripped, I rather enjoyed this one. Some lovely colours and decay going on inside.
What I will say is; there are signs everywhere warning of Lead Chromate contamination inside from the production of coloured dyes. It is absolutely everywhere! Lovely…..!
Built at the end of the 18th or in the early 19th centuries; Chisworth Works was as a cotton band manufactory. During these times, the site was called “Higher Mill”. It appears that the original building was extended twice to the rear in its past, as there are noticable lines in the mortarwork and mismatches in the courses along the south-west elevation.
It is thought that these extensions took place before 1857 because the building line remains the same on the maps until 1973. The site was used as a dyeing works by 1973; and there was a large T-shaped extension at the rear which looks to have been added in two stages.
The only change a decade later, was the construction of a square loading ramp at the front. The outline of the site today is the same as it was in 1984. E.P. Bray began "winding-up" by 2006 and was dissolved/liquidised and the site shut down in September that year.
Holdings Country Pottery, Oswaldtwistle, Lancashire – July 2017
Another backlog lol!
Back in July, Mookster and myself headed up north for a 650 mile round trip Road Trip with about two A4 pages of sites to do! Very good news; however we only managed four out of about twenty due to loud alarms going off, places being sealed up tight, horrible undergrowth and pretty much every explore failing thing you can think of, such is life. One thing is for certain, “you cant do em all!”
Holding's Country Pottery was originally founded in 1842 by James Holding. The original pottery was built a short distance away in Gaulkthorn, another outlying area of Oswaldtwistle.
James Holding moved his business to Broadfield in 1860, and in 1900 his son Grimshaw Holding; set up the pottery on the present site where the derelict remains sit. From then till it’s closure; the pottery stayed here and the business was passed down from father to son until it's decline.
Holdings was originally powered by a steam engine; sadly no longer in situ, but the line shafting is still present.
There were magazines and brochures pointing to a late 1990s closure. I am thinking around 1999-2000 at a guess.
The last piece of Pye.
I’m sure everyone who visited Pyestock before it was demolished will remember the Anechoic Facility, that one last bit of the puzzle that couldn’t be visited. The blue-tailed building was still in use long after the demolition of the rest of the site, and is the only surviving part of Pyestock’s original host of facilities. This last part of the site has now also closed.
Visited with @SpiderMonkey and @darbians.
The National Gas Turbine Establishment.
For those who don’t know, NGTE Pyestock - The National Gas Turbine Establishment - was a huge industrial site in Fleet, Hampshire. The site was used to test jet engines during their development and could simulate the conditions of flight in huge wind tunnels. Large scale expansion took place throughout the 50s and 60s to facilitate the much larger jet engines being developed such as those used on Concorde. The site finally closed in 2000 due to a decline in jet engine development and the advent of computer aided simulations.
The Noise Test Facility
A lot of research into noise took place at NGTE over the years, and the first anechoic chamber was built in the early 1960s. The increasing demand for quieter aircraft stimulated the more research work, and as a result a larger test facility capable of undertaking large scale noise tests on a variety of gas turbine components opened in the 1970s.
The new facility consisted of two main laboratories, fully independent of each other. These were the Absorber Rig Facility and the Anechoic Chamber facility. The Absorber Rig Facility was the first to be completed and it came into service in the summer of 1972. The Anechoic Chamber Facility was commissioned just over one year later in early 1974.

The blue air intakes and associated fans were installed during a refit in the 1990s
The plans below show the general layout of the building. The anechoic chamber is central with silenced air intakes to the left and the silenced exhaust duct and extraction fans to the right. The induced airflow passes through the anechoic chamber where the noise tests were conducted.
The Anechoic Facility has a 10,000 cubic metre chamber for noise testing in which the enclosed working volume has nearly zero noise reflection, thereby reproducing environmental conditions which can be compared to those in flight, and permits work to separately identify the source and direction of noise wave phenomena. The building is principally intended for the noise testing of jets, turbines and certain configurations of acoustically lined ducts.
Broadly, the facility consists of an acoustically lined main test chamber 85ft wide and 46ft high with an overall length of 88ft, but which is reduced to 52ft at the working section. The jet flow from the main noise source is projected towards an acoustically lined, flared duct 28ft diameter at inlet with a 20ft diameter throat, which acts as an exhaust inducer.

View from a hatch at the top of the working section, showing ceiling mounted crane Three observation galleries were positioned around the chamber. Each could be retracted to preserve the room's anechoic properties:
The most striking feature of the anechoic chamber itself is the sound reflecting wedges of which there are nearly 7,000 units covering the walls, ceiling and floor. Three individual wedges are mounted together on a base-frame to form each single unit 610mm square; these units are then arranged over the chamber surfaces so that each successive unit has its wedge peak edges at right angles to the neighbouring unit.
The working section was modified during refurbishment in the 1990s. A permanent nozzle was fitted through which high pressure air could be blown in using the blue external assembly shown in earlier pictures.
Inside the working section the area where jet engines would be positioned was replaced with a network of pipelines feeding the new nozzle.

The rig room before the refit
The exhaust collector was responsible for transferring the jet engine exhaust gasses and induced air from the chamber to the exhaust silencing structure behind it. It is acoustically treated around its periphery, this lagging consists of heavy density rockwool 8in thick, faced with cotton sheeting and perforated galvanised mild steel sheet. The duct itself is prefabricated from 0.25in thick steel plate and has a total length of 35ft.

Behind the exhaust collector
Air and exhaust gasses then pass into the exhaust silencing structure. The main features of the structure, other than the exhaust collector are the acoustically slabbed walls of the concrete ducts which reverse the flowpath, two sets of silencing exit splitters, high and low frequency, and the ten exhaust extraction fans.
Low frequency splitters on the left, and one of the two sets of high frequency splitters on the right. The pole is a fixed microphone boom.

The fan units themselves are double axial units having two counter-rotating six bladed fans in each pod, both with its own electric motor.
One of the two sets of five extract fans, plus one redundant space for an additional fan.
The new arrangement after the refit was particularly suited to testing ducts and propellers. One such item was found boxed up below the working section. This was possibly the last item to be tested at the site.
A separate building, houses the control and engineering service equipment. This building has three floors and the heavy service plant was originally installed on the lower floor with the service supplies fed to the rig room via an underground communication duct; the main control room is on the middle floor, while the upper floor houses the ancillary electronic equipment.

The control room was refitted with computerised equipment during the refurbishment in the 1990s. All that remains from the original control room is a single panel, the Plant Controller board.
visited this one early morning.was not expecting great things from this place turns out it was one of the nicest houses I have been too.the place was a bit different to what I am normally use to with stuff from the sixties to the eighties.it had a real vibrant feel to the place,but the same smell and feel as any other derp.
