Abstract: 512,070. Pile fabrics. ISSUM, H. VAN, ROAN, (formerly ROSENMANN), H. M., and VERSPAGEN, J. March 7, 1938, Nos. 7112 and 13318. [Classes 142 (ii) and 142 (iv)] In weaving two loop pile fabrics 4, 5, Fig. 4, face to face in a double shuttle loom with temporary or blind warps 13 and temporary wefts 26, 27, the pile warp 17, 18 is positively drawn off and when the pile warp 18 of the lower fabric is raised above the blind warp, a weft 26 is inserted beneath it by the upper shuttle and simultaneously the lower shuttle inserts a weft 24 into the lower fabric, similarly a weft 27 is inserted below the pile warp 17 by the lower shuttle whilst the upper shuttle is inserting a weft in the upper fabric. The blind warp is not shed and may be stationary or be positively let off as weaving proceeds and be severed afterwards so that the two fabrics may separate or the pile supporting wefts may be withdrawn first and the blind warp reeled for re-use. The, fabrics may have loop pile of varying heights, or cut and uncut pile as shown in Fig. 2, or both as shown in Fig. 8. The cut pile may be formed by threads 35, 36 of different colours &c. drawn from cheeses on a creel 37 and controlled by jacquard operated healds 38, 39 so as to be woven into the fabric 5 and to pass into the fabric 4 at intervals. The uncut loops are formed by pile warps 19, 20 supplied by a beam 21, positively let off at 21' and controlled by healds 22, 22<1>. A travelling blind warp 31 of cotton &c. from a beam 32 is positively fed at 33 and held in a middle position by a stationary heald 15. Ground warp threads 2, 3, 8, 9 are supplied from beams 1, 10 and controlled by healds 6, 7, 11, 12. The fabrics are correctly spaced apart by adjusting dividing rollers 8, and also adjusting the ground warp healds. Threads 40 from the creel are controlled by the heald 41 and are woven into the fabric 4 so that this may have the same structure as the fabric 5. The blind and pile warps are severed by a knife 43. In weaving fabrics with pile loops of varying heights the pile warps 50, 53 for the two fabrics are controlled by positive let off motions 52, 55 under jacquard or dobby control, one letting off a short length while the other lets off a long length or vise versa but the total let off by both being constant. The cloth covered measuring roller 66 of each let off motion has a gear wheel with which driven pinions 67, 68, 77 of various sizes are caused to mesh by moving frames 69 and 76. These are controlled by cords 71, 72, 78, 79 and springs connected to jacquard or dobby hooks. A modification - is described wherein pile warp threads forming both cut and uncut pile are used. The blind warp may be of cotton &c. or of wire. Each fabric may have two pile warps used alternately to form loop pile. The fabrics may be used for moquettes, tapestry, table cloths &c. According to the first Provisional Specification, the surplus wefts may be withdrawn by conical rollers.

Title: Improvements relating to photographic hardening baths and processes
IPC: G03C5/26
Filed: 1943-05-07
Abstract: 565,551. Photographic hardening baths: KODAK, Ltd. (Eastman Kodak Co., and Vittum, P. W.). May 7, 1943, No. 7272. [Class 98 (ii)] A colour-developed gelatine silver salt emulsion is hardened, before removal of the developed silver, with an aqueous sulphite-free bath containing a gelatine hardening agent, an organic acid, and a buffer compound, with or without a boron compound such as boric acid or borax. The hardening agent may be potassium or chrome alum, the organic acid acetic acid, and the buffer compound sodium or other acetate, a citrate, or a borate. The bath reduces the tendency for the production of stain on removalof the developed silver. An example of a hardening bath is given. Three-layer colour photographic material may have as the cyan coupler in'the red-sensitive layer o-acetaminophenol, and after exposure, colour development, and hardening, may be treated first with a ferricyanide solution and then with a hypo solution. The colour negative produced may be printed on to similar material. The material may be of the kinds specified in Specifications 524,154, 524,554, 524,555 and 541,589. The material may also be processed to a positive by reversal colour development, the hardening bath being applied after the colour development. The hardening bath may also be employed after the separate re-exposures and colour developments involved in the reversal processing of material as in Specification 507,841 in which the couplers are not incorporated in the emulsions. The absence of sulphite in the hardening bath is advantageous where one of the following couplers is used : sebacic acid di-(3-hydroxyanilide, sebacic acid di-(2-hydroxyanilide), 2- hydroxy - 4<1> - (3 - phenoxybenzamido) diphenyl, 1 - hydroxy - 2 - (N - y - phenyl - n - propyl: N - phenyl) - naphthamide, N - n - butyl - 2 - cyanacetylnaphthalene - 7 - sulphanilide, N - n - amyl - 2 - cyanacetylcoumarone- 5 - - (p - ter. - amylsulphanilide), and p - tert. - butylphenoxyethyl p - benzoylacetammobenzenesulphonate.

Title: Improvements in fuel injection systems for internal combustion engines
IPC: F02M69/20
Filed: 1960-03-02
Abstract: 872,264. Fuel injection systems. GENERAL MOTORS CORPORATION. March 2, 1960 [March 24, 1959], No. 7368/60. Class 7(3). In a fuel injection system in which fuel under pressure is delivered by an injection pump to a fuel metering valve, the metering valve includes a movable valve member, the valve member is movable to meter the fuel by controlling the amount of fuel by-passed back to the injection pump inlet side, fuel is delivered from the valve to an injection nozzle, the nozzle includes a valve for controlling the rate of fuel flow through it and the nozzle valve is responsive to the fuel pressure differential between the pump inlet and outlet to render the supply of fuel metered to the engine independent of variations in pump operation. As shown the air induction system comprises an air inlet 12 a plenum chamber 18 and cylinder intake passages 16. The fuel reservoir 44 is connected to the outlet of a low pressure transfer pump (not shown). An injection pump 46 comprises gears 47, 49 and delivers fuel through a passage 52 to a fuel metering by-pass valve 50. The extent to which the ball 58 is raised is determined by an arm 64 movable by a diaphragm 70 responsive to the Venturi pressure drop. The chamber 74 is connected with the air inlet 12 upstream of the throttle valve. A chamber 120 (Fig. 1) is connected to the plenum chamber 18. When the throttle valve 36 is suddenly opened, the vacuum in the chamber 120 decreases sufficiently to permit the spring 126 to move the diaphragm 118 and stud 86 upwardly. This decreases the quantity of fuel by-passed. A pair of nozzle jets 130 is formed in each nozzle 34 (Figs. 4 and 6). The inlet 134 is connected to the fuel supply conduits 32 and 28 and the inlet 152 is connected by a pipe 168 with the fuel reservoir 44. By making the face of the diaphragm 164 that co-operates with the planar surface 174 with a controlled degree of roughness, the sticking of the diaphragm is practically eliminated. The way in which a satisfactory amount of roughness can be obtained is described in detail, the diaphragm being of sheet rubber.
