Patent GB-414703-A (GB)
Title: Improvements in and relating to resinous compositions
IPC: C08L5/00
Filed: 1933-02-08
Abstract: A water resistant thermoplastic composition is obtained by the admixture of a polyvinyl resin and the exudations from plants of the species Xanthorrhaea, commonly known as acaroid gum, or yacca gum. The addition of the natural resin has the effect of stiffening the polyvinyl resin at temperatures slightly above atmospheric in addition to improving the resistance to moisture to about the same extent as copal resin, without lowering the softening point.  The admixture may be effected on the mixing rolls or in solution in a common solvent such as butyl or ethyl acetate, ethyl alcohol or acetone.  The yacca gum may be used in its natural state or it may be first purified by steam distillation and filtration, or by solution in alkali, filtration, and precipitation by acid.  In examples yacca gum is admixed with polyvinyl acetate and with polyvinyl resins prepared according to Specification 351,082, [Group IV], or by aldehyde condensation of 70 per cent hydrolyzed polyvinyl acetate of 15 centipoises viscosity.  The mixed resin can also be mixed with further resinous admixtures such as carnauba wax, dyestuffs, fillers such as sawdust, sulphite wood and limestone, fibres, pigments and abrasives.

Abstract: 776,640. Jet propulsion plant. MINISTER OF SUPPLY. Feb. 10, 1953 [Feb. 13, 1952], No. 3892/52. Class 110 (3). In a jet reaction motor, oxidant, e.g. hydrogen peroxide, is fed under pressure to a valve 15 which is actuated by said oxidant to open firstly a connection to the combustion chamber 12 for fuel, e.g. kerosene, under pressure (via pipes 21 and 26), and secondly a connection (in pipe 28) for the oxidant to flow to the combustion chamber and, after ignition, to raise the combustion chamber pressure to a given figure, a second valve means 31 is actuated by said combustion chamber pressure to open a further connection for oxidant which then flows under pressure to the chamber 12, whilst means controlled by the second valve are provided for subsequently allowing a flow of oxidant under pressure to the combustion chamber at an increased rate sufficient for full thrust running. Hydrogen peroxide passes via pipe 11 to the cooling jacket of chamber 12, thence via pipe 14 to valve 15, moving piston 20. Part of the oxidant flows to the centre of chamber 12 via valve 13a. Movement of piston 20 allows fuel to pass from pipe 24 to chamber 16 and so to first stage nozzles of chamber 12 via pipe 26, and to second stage nozzles via pipe 27; ports leading to oxidant pipe 28 are also uncovered, so that oxidant flows to chamber 12 and to valve 31 to act on piston 34. Member 18 damps the movement of piston 20. With the pressure in chamber 12 reaching a given figure, first a restricted flow of oxidant passes through valve 31 to pipes 32 and 33, and then, with full ignition, valve 31 is fully opened. Special fuel from container 25 giving rise to spontaneous ignition with the oxidant may precede the kerosene.

Title: Motor control apparatus for driving an output shaft at substantially constant speed
IPC: F16D27/105
Filed: 1960-02-04
Abstract: 879,845. Speed governors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 4, 1960 [Feb. 6, 1959], No. 3964/60. Class 57. An output shaft 11 is driven at constant speed by means comprising a torsionally flexible shaft 18 driven by a non-synchronous motor 16 and connected to the shaft 11 through a controllable clutch 21 and a synchronous motor 31 which is automatically coupled to the shaft 11 by a clutch 36 when the speed of the shaft at least equals that of the synchronous motor. The clutch 21 is a coil spring which surrounds the shafts 11 and 18 with clearance and is operable by a roller 22 actuated by a solenoid 24. The clutch 36 is also a coil spring which surrounds the shaft 11 and the shaft 33 of the motor 31 with slight clearance only such that it is automatically engaged when the speed of shaft 11 tends to exceed that of the motor 31. The shaft 11 has a wheel 12 keyed thereto which drives a load (not shown) through a belt 13. In operation, starting with the shaft 11 at rest and the motors 16 and 31 running freely with the motor 16 driving the shaft 18 at a speed greater than the synchronous speed of the motor 31, the solenoid 24 is energized to engage the clutch 21 whereby the shaft 11 is accelerated until its speed reaches that of the motor 31 when the clutch 36 automatically engages and the complete system is thereafter controlled to run at the speed of the synchronous motor 31. In a modification, Fig. 2 (not shown), the motor 16 drives two flexible shafts 18, each connectable to the shaft 11 by clutch means and rotating in opposite directions to provide forward or reverse drive of the shaft 11.
