Title: Improvements in or relating to injection molding apparatus
IPC: B29C45/46
Filed: 1944-12-01
Abstract: 605,867. Yielding shaft couplings. STEVENS, A. H. (Chrysler Corporation). Dec. 1, 1944, No. 24035. [Class 80 (ii)] [Also in Groups V, XXX and XXXVII] A shaft 31 is driven by an electric motor (not shown) and the speed of the shaft varies by reason of the work it does (compressing plastic material). Means are provided for accmnulating energy in a torsion spring when the shaft slows down and for releasing the energy when the shaft speeds up. On an extension 82 of the shaft 31 is fixed a fly-wheel 81 having arcuate slots 90 through which pass screws 89 which are threaded into a coupling 85 secured to another shaft 84 driven by an air or electric motor. A torsion spring 91 is secured at one end A to the fly-wheel and at the other end B to the coupling 85. Both shafts rotate counterclockwise (Fig. 5). When shaft 31 lags (because of the resistance of plastic material being compressed), the coupling over-runs the fly-wheel and the spring is wound up, and when shaft 31 speeds up, the spring unwinds and speeds up the shaft still further.

Title: Process for the manufacture of fatty acid esters of aliphatic polyhydric alcohols and monosaccharides
Inventor: WICKER RONALD JAMES
IPC: C07H13/06
Filed: 1956-08-03
Abstract: Fatty acid esters of aliphatic polyhydric alcohols or monosaccharides are made by reacting a fatty acid containing from 8 to 24 carbon atoms in the molecule with a C6 aliphatic alcohol or a C6 monosaccharide in the presence of an acid condensing agent and in the presence of the monomethylamide, dimethylamide, monoethylamide, diethylamide, cyclic internal N-methlyamide, cyclic internal N-ethylamide or unsubstituted amide of an aliphatic carboxylic acid, which amide melts at a temperature below 130 DEG C., or dimethyl sulphoxide or diethyl sulphoxide.  Preferred solvents are N,N-dimethylformamide and N-methyl-2-pyrrolidone.  Suitable fatty acids are lauric, palmitic, oleic and stearic acid.  When the fatty acid is not very soluble in the amide, a further solvent, such as dioxane or ethylene glycol monomethyl ether, may be added.  Sorbitol and mannitol are suitable alcohols and glucose is a suitable monosaccharide.  The condensing agent may be p-toluene sulphonic acid.

Title: Photographic copying process
Inventor: JACKSON ANTHONY ERNEST
IPC: G03C5/315
Filed: 1951-10-16
Abstract: 715,961. Photographic copying processes; photomechanical printing plates. KODAK, Ltd. Aug. 18, 1952 [Oct. 16, 1951], No. 24069/51. Class 98(2) A latent line or half-tone image is formed in a gelatino-silver halide emulsion layer on a support preferably of paper by contact, reflex, projection or camera exposure and processed to form both hardened and complementary unhardened images by methods (a) developing in a tanning developer, forming a complementary latent image in the emulsion and developing in a non-tanning developer, (b) developing in a non-tanning developer, forming a complementary latent image and developing in a tanning developer, or (c) developing in a tanning developer and treating to reduce residual silver halide in the complementary areas to silver without hardening such areas and thereafter transferring the unhardened gelatin together with the silver contained therein by contact on to a second support at elevated temperature as of 75-110‹F. The transferred image is thus negative in method (b) and positive in methods (a) and (c) to the original subject matter and may be revealed by pulling the two supports apart. Sodium sulphide may be used in method (c) to blacken the residual silver halide. In application of the invention to printing plates, including rollers, the second support is constituted by a printing plate and the transferred image is hardened as with alum or formaldehyde to form a lithographic ink accepter or an etching resist. A single example describes reflex printing of a line document, treatment in a pyro developer, washing, treatment in bright light in a metolquinol developer, washing again, pressing into contact.with plain paper, heating, and peeling off the paper to reveal the positive silver image thereon. Specification 655.274 is referred to.

Title: Improvements in or relating to relay systems for protecting alternating current circuits
IPC: H02H3/08
Filed: 1949-09-20
Abstract: 661,449. Protective cut-out arrangements. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 20, 1949. [Nov. 26, 1948] No. 24161/49 Class 38 (v). In a protective system, the relay arrangement associated with each phase of the protected circuit, comprises a directional relay 32 controlling an overcurrent timing relay 50, the directional relay being restrained against operation except under certain fault conditions, so that the overcurrent relay, which is normally inoperative, may be given a setting below the normal full load current of the protected circuit if desired. In the relay arrangement associated with phase A, the directional relay 32 has a voltage winding 42 energized in accordance with the voltage between phases A and C by means of voltage transformers 26 and auxiliary voltage bus bars a, b, c. The current windings 44, 46 of the directional relay are connected across the winding of an auto-transformer 80, this transformer winding being connected to a current transformer 28A through the exciting winding 58 of the overcurrent relay, and a neutral conductor 28N and also through a tap selector 87. Inductively coupled with the winding of the autotransformer 80 is a winding 88, which is energized through an impedance 90 from the voltage bars a b. Thus the actual current which flows in the relay windings 44, 46 is the resultant of a component proportional to the line current of phase A and a component proportional to the voltage between phases A and B the latter component, due to the impedance 90, being in phase opposition to voltage across the winding 42 and so providing the restraint. In the event of a line or ground fault involving phases A and B, the voltage between these phases is substantially reduced and the restraint is accordingly reduced, so permitting the relay 32, if the fault current flows in the appropriate direction, to close its contacts 48. The closure of these contacts completes a circuit containing auxiliary windings 60, 61 and a winding 62 inductively coupled to the main or exciting winding 58 of the overcurrent relay. The windings 60, 61 are energised and the overcurrent relay closes its contacts 66 to cause the tripping of a circuit-breaker 20. The overcurrent timing relay is provided with a damping magnet (not shown) and means may be provided to vary the effective number of turns of its main winding 58.

Title: Apparatus for homogenising viscose
IPC: B01F29/63
Filed: 1956-08-08
Abstract: <PICT:0820176/IV (a)/1> An apparatus for homogenizing viscose by causing solution of undissolved particles of cellulose xanthate in the viscose comprises a tube closed at one end and having distributed over its entire length openings through which the viscose can be sprayed under pressure, a hollow drum concentrically surrounding the tube, the drum being rotatable at high speed and having on its inside wall pointed baffle members directed towards the axis of the tube, on to which members viscose sprayed through the openings of the tube impinges, openings between the members for the passage of the viscose through the wall of the drum, and a stationary closed container surrounding the drum and having at the bottom a discharge opening for the viscose.  As shown in Fig. 1, viscose is forced at a pressure of 5-25 atm. gauge by means of a pump 1 through a stationary straight tube 2 having openings 3 into a drum 4 rotating at 3000-8000 r.p.m. The openings 3 may be slot-shaped and arranged parallel or at right-angles to the axis of the tube 2, and are distributed over the entire length of the tube.  The jets of viscose discharged from the openings impinge on conical pointed elements 5 which act as baffle members and which project from the inner cylindrical surface of the drum towards the p  axis of the tube 2.  Any relatively coarse undissolved particles in the viscose are thereby disintegrated and dispersed in the viscose, which by centrifugal force is discharged through openings 6 in the cylindrical wall of the drum on to the walls of the stationary casing 7 surrounding the drum.  The homogenized viscose is withdrawn from the casing through the bottom outlet 8 by means of a pump and can be readily filtered.  The openings 6 either have the shape of truncated cones narrowing in the outward direction or are of cylindrical shape with a flared inlet. In a modification of the apparatus the drum is concentrically surrounded by a second larger drum of similar design and the openings in the cylindrical wall of the second drum may be narrower than those in the wall of the inner drum.  The second drum is surrounded by a fixed casing as in the form of the apparatus above described.  The directions of rotation and speeds of the two drums are preferably different, or the drums may be rotated in the same direction but at different speeds.
