Title: Improvements in or relating to stereoscopic cameras
IPC: G03B35/10
Filed: 1923-08-21
Abstract: 224,954. Girsdansky, M. Aug. 21, 1923. Cameras, stereoscopic ; cameras for taking a series of photographs on one plate.-Stereoscopic photographs are produced by using in front of the lens of a single-lens photographic or kinematographic camera a movable refracting prism, or pairs of refracting prisms or equivalent lens structures. In one form, Fig. 2, a single prism F is rotatably mounted so as to deflect the imagein turn to the sides A, B of the sensitive plate. Or two prisms may be used and mounted, with their apices adjacent, so as to be slidable in turn in front of the lens to give the two images. Where pairs of prisms or equivalent lens structures are used, in the constructions described two pairs, successively brought in front of the lens, are employed, each pair comprising semi-circular prisms of opposite signs. In one form, Figs. 9 and 11, two circular holders 20, 21 carry each a plus and minus prisms 0, N' M, P, the prisms on rotation of the holders being brought in front of the lens E in pairs of opposite sign. The shutter is closed during the change over from one arrangement to the, other. In a modification, the pairs of prisms are. mounted on rotatable shafts so that elements of similar sign move in the same plane. In other forms, the angularity of one of the elements of a pair is changed to compensate for its additional distance from the plate, or each circular holder s, Fig. 18, may carry two elements of the same sign -A, -B or +C, +D, the periphery of one element B or D being brought to the centre of the other A or C. The portions s, t outside the holder z are removed, and may be fitted into the spaces x, y left within the holder. In a further form, Figs. 19 and 21, pairs 1, 2; 3, 4 of semi-circular portions are cut from a, plus lens Q each pair being fitted in a circular holder and used in connection with a pair 5, 6, Fi<g>. 2, 3, 7, 8, Fig. 24, cut. from a minus lens. The sections instead of being cut from the lenses may be ground directly from specifications corresponding to the lens and section required. When used for producing kinematograph films, the movement of the prism holders may be continuous and synchronized with and preferably operated from the film-operating means. Staggering of the images on the kinemat'ograph film may be prevented by using two sets a, b, c, d,; e, f, g, h, Fig. 12, of the elements so that the stereoscopic views produced by one set are so directed by the second set as to be placed on the film r in a continuous line.

Title: Improvements in and relating to the production of artificial filaments having a variable denier along their length
Inventor: SUTCLIFFE BILLIE
IPC: D01D5/20
Filed: 1955-07-22
Abstract: <PICT:0804303/IV (a)/1> Apparatus for the production of slub yarn from a fibre-forming material comprises a main supply line for the material, a spinning jet, a primary feed line containing a pump for feeding material at a constant rate from the main line to the jet, a secondary feed line containing an auxiliary pump for feeding material at a constant rate from the main line to a three-way valve in the secondary feed line between the auxiliary pump and the jet, and means to operate the valve to cut-off the supply of material to the jet intermittently and divert the balance of the supply back to the main supply line by a pipe leading directly from the valve to the main supply line.  The three-way valve may be of the oscillating-plug type, the rotary-plug type, the rotary-disc type or the oscillating-slide type.  Suitable constructions of valves are described.  In Fig. 1 an uninterrupted flow of fibre-forming material through the main supply line 1, primary feed line 2 and feed pump 3 to spinning jet 4 determines the basic denier of the yarn to be produced.  An auxiliary supply of fibre-forming material is taken from line 1, through the secondary feed line 5 and auxiliary pump 6, to the inlet branch 7 of three-way valve 8. This flow of fibre-forming material is interrupted by the operation of the valve 8 and is directed alternately through outlet branch 9 and pipe 10 to jet 4 or through the other outlet branch 11 and by-pass line 12 to the main supply line 1.  The rate at which the valve 8 is operated determines the length and spacing of the slub on the fibre-forming material supplied to the jet from feed pump 3.  The valve-actuating mechanism may be a cam, a solenoid and spring return or an impacting device and spring return, and may be operated at regular or irregular intervals. The apparatus may be used in the production of slub yarn from fibre-forming materials such as viscose, casein, cellulose acetate, nylon, polyethylene terephthalate or polyacrylonitrile by the wet, dry or melt-spinning process.  Specifications 579,069 and 589,038, [both in Group IV], are referred to.

Title: Improvements in high vacuum pumps
Inventor: GARLIN PAUL
IPC: H01J41/16
Filed: 1958-07-03
Abstract: 892,122. Ion getter pumps. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 3, 1958 [July 5, 1957], No. 21373/58, Class 39(1) A very high vacuum pump capable of pumping inert gases comprises a pump body containing a getter vaporizer a gas trap chamber in communication with said pump body for condensing at least the greater part of any gas being pumped which is not extracted in said pump body by gettering, and means for evacuating said gas trap chamber. The apparatus shown comprises a pump body C cooled by water circulating in conduits 3. A crucible 5 of refractory material such as tantalum carbide supported on a high voltage lead 4 is heated by a filament 6 connected to low voltage leads 7. A mechanical system 8 feeds a wire 10 of getter material, e.g. titanium through a guide 9 to the crucible 5. A screen 11 of coaxial metal cylinders prevents vaporized getter metal from condensing in the chamber E to be evacuated. A passage D communicates with a liquid gas trap P comprising a vessel 15a, containing liquefied gas 15 e.g. helium, thermally insulated and pre-cooled by a liquid nitrogen jacket 16 and a system of screens 17. Two helical baffles 20 and 21 limit the radiation of heat from the pump body C to the trap P. An intermediate zone F communicates with a mechanical fore pump (not shown) through a sealing valve 19. The joints between the various components are made gas-tight by seals each comprising a metal ring 23 and a rubber ring 24 with provision for evacuating the space 25 between the rings. In operation, the titanium wire 10 is fed to the crucible 5 where it is vaporized. The vapour condenses on the cold wall of the pump body C and fixes chemically active gases such as hydrogen, oxygen and nitrogen. Rare gases, with the exception of helium, condense on the cold wall of the liquid helium trap. Helium is removed by the ionization pumping system formed by the filament 6 and the wall of the pump body C which is maintained at a low potential. Evaporation of the titanium may be stopped for a time so that there is no degassing of the wire to enable pressures below 10<SP>-9</SP> mm. of mercury to be reached. Curves are given plotting pumping rate against pressure for air, nitrogen, oxygen and hydrogen. Specification 768,003 is referred to.

Title: Improvements in and connected with the dyeing of animal fibres and fabrics of a protein nature
IPC: D06P3/32
Filed: 1925-06-25
Abstract: Animal fibres and fabrics, such as wool, fur, bristles, silk, leather, and feathers, are subjected to the action of ammonia and ozonized air or ozone (produced for example by ultra-violet radiation or silent discharge), whereby their power of absorbing dyestuffs is improved and in some cases mordants are not required. In an example the fibres or fabrics are soaked with a 5 per cent ammonia solution and, while still wet, placed in a closed chamber, through which a current of ozonized air saturated with water is passing.  From time to time test pieces are removed and if acid the fibre or fabric is again soaked in ammonia.  After treatment, the material is washed and may be dyed immediately.

Abstract: 1,101,772. Tubular heat exchangers. BABCOCK & WILCOX Ltd. 24 May, 1965 [25 May, 1964], No. 21553/64. Heading F4S. In a heat exchanger in which inlet and outlet headers 14, 16 are disposed in a boundary wall 12 of a pressure vessel 10, the headers can move relative to each other to accommodate differential expansion. As shown, a web member forms a sealed expansion joint between the headers and comprises two sleeves 24, 26 respectively made of stainless steel and welded by one edge thereof one to each header, the other edges of the sleeves being joined together by a ring 34. In use, steam flows through the headers and through U-tubes 44 connected thereto. A baffle comprising concentric cylinders 58, 60 constrains hot liquid sodium entering the vessel through a duct 46, to flow in a sinuous path to outlets 68. The upper part of the vessel 10 including the space between the cylinders 58, 60 of the baffle may contain an inert gas such as argon. The gas forms a blanket at the top of the vessel and prevents contact of the hot sodium with the upper surface of the vessel and hence damage to the web joint.
