Patent GB-740661-A (GB)
Abstract: 740,661. Optical pointers. SOC. DE PROSPECTION ELECTRIQUE PROCEDES SCHLUMBERGER. Oct. 14, 1953 [Nov. 14, 1952], No. 28360/53. Class 97 (1). In an indicating system in which an angularly moving mirror 3, immersed in a liquid 2, reflects a projected beam on to a screen, the various transparent media, including the liquid 1 and liquid retaining wall 7, traversed by the light travelling from a fixed object 4, to its.image 41, have approximately all the same refractive index. Preferably the object is placed and the image formed on the outermost surfaces of the media. In the form shown in Fig. 2, a solid transparent block 8 of rectangular cross-section and of the same refractive index as the liquid 2 has a concave spherical surface in contact with the convex spherical surface of a block 7 of similar material, the pole of the mirror 3 being at the centre of curvature of both surfaces so that the block 8 can be angularly displaced to enable the initial adjustment of the position of the illuminated object 4 and the image 4<SP>1</SP> to be made. The image is formed after a reflection at 12 and is projected on to the translucent screen 14 by a microscope objective 13. Specifications 606,521 and 632,769, [both in Group XXXVI], are referred to.

Title: Mass transfer device
IPC: A61H31/02
Filed: 1978-08-11
Abstract: The invention relates to a device for conveying a medium with simultaneous exchange of gas between the conveying medium and a surrounding atmosphere. The device compresses a plurality of resilient hoses 105 which permit the passage of gas and which are tensioned by the rotor 101 of a roller pump. The pump hoses are subjected to pressure from the rotor in such a manner that they are subjected to undulating changes in their cross-section and this pressure and the changes in cross-section achieve a very effective exchange of gas. By encapsulating the rotor in a casing 111 any desired atmosphere may be created for the exchange of gas. By having a liquid in the casing, the device may be used as a dialyser. <IMAGE>

Patent GB-2034012-A (GB)
Title: Method and Apparatus for Producing Process Steam
IPC: F04C23/00
Filed: 1979-10-22
Abstract: Process steam is produced from a feed of low pressure steam by setting the water content of a feed of water and steam at a selected water-steam ratio, injecting the two-phase mixture into a helical screw compressor in which the mixture is compressed, and vaporising the water in the feed during compression. The water-steam ratio is set so that, given the compression ratio characteristic of the compressor and the temperature and pressure of the feed, process steam at a predetermined temperature and pressure is produced. The compression proceeds along a direct, energy-efficient thermodynamic path. The apparatus used for producing the process steam comprises a screw compressor 20 having a steam and water inlet 18 connected through a water content control device 16 to a steam source 10. Further steam may be supplied from a waste heat boiler 14. <IMAGE>
Patent GB-2063379-A (GB)
Title: Improvements relating to vibrators
IPC: F01B11/06
Filed: 1979-11-15
Abstract: A pneumatic vibrator has a free piston (6) in a cylinder (4) with a central air inlet (8, 9) and exhaust (11) ports to each side. The piston has ducts (10) which cooperate with the inlet to admit air to whichever is the reduced volume end chamber, the piston itself acting as a valve member to open and close the ports to maintain reciprocation. The exhaust from one end is made freer than that from the other end so that, when the air supply is cut off, the piston tends to stop at that one end. The inlet then registers with the piston duct which will direct air to said one end when the air supply is resumed. <IMAGE>
Patent GB-2039644-A (GB)
Title: Vehicle friction brake
IPC: F16D51/20
Filed: 1979-11-28
Abstract: The Specification describes a vehicle friction brake having a brake shoe (4) bearing a friction lining (9) and mounted on a support plate (2) for movement across the plate towards and away from a brake drum rotation of which is to be braked. The shoe (4) is biased by a spring (12) towards the support plate (2) and as shown the friction lining (9) overlaps the edge of the shoe (4) to engage a pad, lining or coating of friction material (11) mounted on the plate (2) or alternatively the plate (2) itself. In an alternative arrangement the friction material (11) engages either the shoe (4) itself or the shoe (4) and lining (9) and the lining (9) does not overlap the shoe (4). The friction between the plate (2) and shoe (4) prevents noise-producing vibration during braking. <IMAGE>

Title: Sinker for knitting machines for producing a knitted plush fabric
IPC: D04B27/04
Filed: 1980-08-12
Abstract: A known sinker for use in knitting plush fabrics was expensive to manufacture in view of the complexity of its shape and did not admit of adjustment of the relative length of the loops of the plush and ground fabrics. In order to overcome this a sinker is formed of two separate relatively slidable parts 54 and 56 independently operable by means of cutouts 58 and 60 (or butts) cooperating with sinker cams 42 and 44. The upper part 54 has a tongue 76 extending forwardly from a knitting surface 72 and a draw edge 66 for the plush loops while the lower part 56 has a tongue 78 extending forwardly from a draw edge 70 for the ground loops. In a variation the tongue 78 with knitting surface 74 is omitted so that a part of the needle cylinder acts as a knitting surface. In this case the draw edge is formed as a notch. <IMAGE>
