Title: Improvements in and relating to the colouring of cellulose esters and of solutions or compositions containing such esters
IPC: C09B67/20
Filed: 1927-10-11
Abstract: 309,840. Jenkins, W. J., and Imperial Chemical Industries, Ltd. Oct. 11, 1927. Right to Patent relinquished. Compositions containing cellulose esters.- Coloured cellulosic products are prepared by incorporating with a dry non-gelatinized cellulose ester, such as cellulose acetate or nitrate, a colouring material and a non-volatile gelatinizer simultaneously while avoiding liquefaction of the ester. No resins or volatile solvents are present during the grinding, but a non-volatile inert liquid such as linseed oil or raw or blown castor oil may be added to improve the consistency of the mass. When such an addition is made, the gelatinizer may be omitted. In one example, dry nitro-cotton, tricresyl phosphate, and zinc oxide are ground together on rolls until the pigment is sufficiently dispersed, and in another example the gelatinizer is replaced by linseed oil. In a further example, the gelatinizer and linseed oil are both present. Pigmented celluloid can thus be directly prepared. Specifications 165,439 and 309,964 are referred to.

Title: An improved method and apparatus for forging multiple-throw crankshafts
IPC: B21K1/08
Filed: 1959-08-06
Abstract: 896,990. Forging crank-shafts. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. Aug. 6, 1959 [Aug. 6, 1958], No. 26978/59. Class 83 (4). In the forging of multi-throw crank-shafts from round workpieces having rolled-in journals 1 and crank-pin portions 2, the crank webs are first formed and the crank-pins are then offset to the required throw. The workpiece has concentric or eccentric rolled-in crank-pins, Figs. 1-3 (not shown), and is initially induction heated. It is placed in a transversely slidable lower press part 3 which is then moved inwardly into alignment with an upper part 4; the two parts are clamped together by fluid pressure rams 20, 21, Fig. 5 (not shown). Upper dies 10, 11 are then moved downwardly to form the webs in co-operation with lower dies 6, 7 ; thereafter the die 11 only moves downwardly to form the crank-throw which is backed by die 7 mounted on ejector 8. A sliding carriage 14 has a face-plate 15 for setting the angular position of the throws.

Abstract: 820,533. Vehicle hydraulic shock abscrbers; vibration dampers. BENDIX AVIATION CORPORATION. Aug. 27, 1957 [Sept. 10, 1956], No. 27016/57. Class 108(3) A dynamic damper 24 is responsive to unsprung mass vibrations only, and a hydraulic damper 20 is responsive to sprung mass vibrations only. The damper 20 comprises a hydraulic shock absorber connected between the vehicle frame (not shown) and a wheel-carrying arm. The damper 24 (Fig. 7) is mounted directly on the wheel hub. The shock absorber 20 comprises a pair of pistons 34, 36 of similar construction operable within a housing 26 by rockers 33 on a shaft 30. On upward movement of either piston a valve 60 is maintained in closed position, but on downward piston movement the valve 60 is able to lift and permit communication between a reservoir 50 and the cylinder space above the piston to permit the escape of air locks. A cover member 68 is formed with a bore in which is disposed a sleeve 76 (Fig. 5) within which is rotatably mounted a further sleeve 88. The latter is rigid with a spindle 106 which is secured to an inertia mass 108 movement of which is damped by the action of magnetic pole pieces 168, 170, in conjunction with a curvilinear shaped plate 172 rigid with the housing 26. Cavities 72. 74 formed in the cover 68, are connected to the cylinder space above the piston 36, and are connected with the interior of the sleeve 88 for all positions of the latter corresponding to the full range of the movement of the mass 108, by means of ports 90, 92. Deflection of the inertia mass 108 consequent upon movements of the sprung mass, causes ports 94 in the sleeve 88 to move out of register with ports 84 in the sleeve 76 and thus impose a restriction to flow between the cylinder spaces 27, 28. A piston valve 160 is spring loaded at 161 to close the communication between a chamber 86 and a chamber 154 connected with the cylinder 27. On upward' movement of the piston 36 in its cylinder, when a predetermined degree of pressure is reached, pressure acts along a passage 150 leading from the chamber 72 so as to act upon a piston 158 so as to deflect the piston valve 160 against the spring 161 thus connecting the chamber 86 with the chamber 154. On upward movement of the piston 34 pressure developed in the chamber 154 acts directly on the piston valve 160 to deflect it against the spring 161 and so connect the cylinder space 27 with the passage 86 and thence to the chamber 28 via the ports 84, 94, and chambers 72, 74. Chambers 120, 120<SP>1</SP>, at respective ends of the sleeve 76 are connected by passages (Fig. 6, not shown) to the reservoir 50. The dynamic damper comprises a conventional hydraulic shock absorber having a piston 204 and a cylinder 202, on the outer surface of which are slidably mounted masses 208, 214. The latter are connected by a spring 220 to the cylinder 202.
