Title: Improvements in artificial limbs
IPC: A61F2/54
Filed: 1946-01-23
Abstract: 607,001. Artificial limb drive mechanism. MOLLER, A. A., and HOBBS, E. W. Jan. 23, 1946, No. 2228. [Class 81(ii)] An artificial limb comprises an electric motor to eftect relative movement between parts of the limb, a motor starting switch and an automatic device to stop the motor when relative movement is obstructed. As shown the forearm unit 11 is carried by a cylinder 16 mounted in trunnion bearings 17 formed on a swivelling cup at the base of a bucket 10 for the stump. The cylinder houses a motor 18, which drives the pinion 33 through a worm reduction gearing 26, 27, 29, 30 and a " torque switch" 34, and a reversing motor starter 60. A sleeve 45 mounted on a trunnion to slide about a stop on rotation by the lever 14 carries a cam 50, a toothed part-circular rack 44, and a member 57. In one position, Fig. 6 (not shown), the member 57 thrusts aside the clutch 55, and the cam retracts the bolt 42, Fig. 5, which locks the cylinder in the trunnion, so that rolling of the pinion 33 on the rack 44 flexes the arm. Movement of the sleeve displaces the cam 50 allowing the spring pressed bolt 42 to lock, retracts the member 57 and allows pinion 33 to mesh with spring pressed clutch member 55 to drive the shaft 54, by means of dogs 58, 99. The shaft 54 drives, e.g. a hand or other appliance. When flexion or rotation is obstructed the spring blade 35 of switch 34 twists so that contact 36 touches one of contacts 38 to energize the electromagnet 65, and attract the armature 66, an insulating stud 80 on which opens the contacts 68, 168 and stops the motor. The reversing starter 60 carries two slip rings 72, 73 having single axial contacts 75, 76 disposed at opposite ends of a diameter and connected to the supply leads. Each pull on the cord 15 and pawl 64 rotates the star-wheel 62 and the switch through 90 degrees which gives a start, stop, reverse, stop cycle by successive contacts with contacts 77, 78 which connect with the motor brushes 23. Studs 81 on one end of the switch co-operate with a projection 82 to release the contact breaking armature 66 on operation of the switch. A main switch 79 and dry battery are provided in the bucket 10. A rod 83 pivoted to a trunnion at 84 carries a compressed spring 86 which bears against a bracket 85 on the forearm structure to balance its weight. In a wrist attachment modification, Figs. 8 and 9 (not shown), the sliding sleeve selector mechanism does not appear. The Provisional Specification describes the use of an overload relay for stopping the motor, a modified reversing switch having a contact slide, and flexion of the arm by a cord. Specifications 596,206, 596,209 and 596,212 are referred to.

Title: Improvements in or relating to means for testing electrical ignition systems of internal combustion engines
IPC: F02P17/02
Filed: 1943-02-12
Abstract: 563,502. Testing ignition. NAPIER & SON, Ltd., D., and RAMSAY, F. R. F. Feb. 12, 1943, No. 2362. [Class 7 (iv)] [Also in Group XXXVI] Faults in the ignition systems of internal-combustion engines are identified and located by examination of the trace on an oscillograph of the impulses delivered to the sparking-plugs, the time-base being synchronized with the cycle of the engine. The ignition coil A, B with its primary connected to a battery A<1> and contact-breaker A<2>, and its secondary connected to a distributer B<1> and sparking-plugs C, has its primary coil shunted by a variable resistance E<4> and by a transformer E. The secondary of this transformer is shunted by a condenser E<1> for byepassing high-frequency components and by a potentiometer E<2> for applying the impulses to the vertical plates F', F<2> of a cathode-ray tube F. The plates F<4>, F<5> for giving the time base are connected across a condenser J<1> which is slowly charged from a. H.T. source through a pentode valve K or ohmic resistance and is abruptly discharged through a gas valve J when a synchronizing signal is received on its grid.. This signal is derived from a moving part of the engine, or, as shown, from one of the sparking-plugs C<1>, which is connected through a high resistance G to the primary of a transformer H' having its divided secondary connected to two diode rectifiers in the valve H. The voltage across the load resistance of the diodes is applied to the grid of the triode section of the valve H, the anode of which supplies a triggering voltage to the gas valve J. Reduction of the resistance E reduces the intensity of the sparking-plug impulses and enables incipient faults to be detected. Ignition may be by magnets instead of coil, and a series gap may be interposed between the spark gap C<1> and the connection to the resistance G. The Specification includes a series of traces showing the effects of various defects in the plugs and associated circuits. Supply voltages are taken from A.C. mains, or from a D.C. source through a vibrator interrupter M, switches being provided for selecting the desired supply source. Specifications 495,478 and 495,547 are referred to.

Title: Improvements in or relating to the production of refractory vessels
Inventor: BEST PETER
IPC: C04B26/02
Filed: 1956-01-25
Abstract: A method of preparing a sintered refractory vessel comprises forming a porous vessel of a crude sinterable refractory compound, applying a coating of the pure refractory compound within the porous vessel and sintering to form a unitary body.  The porous vessel may be formed by subjecting a mixture of the crude compound with an organic binder, e.g. polymethyl methacrylate, to compression in a die or by the use of hydraulic pressure applied to a flexible container surrounding such a mixture and presintering.  The coating may be applied by casting a slip of the pure refractory compound in the porous vessel and allowing it to dry, after which the vessel is sintered. Alternatively, application of the coating containing an organic binder, e.g. polymethyl methacrylate, may be made by hydraulic pressure. Presintering is then unnecessary.  In the examples given the compounds are calcium fluoride, alumina or zirconia.ALSO:In a method of preparing a sintered refractory vessel comprising forming a porous vessel of crude sinterable refractory compound, applying a coating of the pure refractory compound within the porous vessel and sintering to form a unitary body.

Title: Improvements in Air Brakes.
Inventor: HENRY PIEPER
IPC: B60T13/66
Filed: 1916-09-04
Abstract: 113,449. Pieper, H. Sept. 4, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Addition to 101,153. Fluid-pressure.-Relates to the brake system described in the parent Specification, in which the pressure air is returned from the brake cylinder 3 to the reservoir 4 after an application, by a solenoid 6 or motor acting directly upon the brake piston 1, and consists in the provision of an electrically controlled valve or valves which is adapted to permit only a restricted supply of pressure air to the brake cylinder when the current is interrupted so that automatic applications of the brakes in the event of interruption of the line current or breakage of a coupling are effected without shock. As shown in Fig. 1, two valves 11, 14 control the supply of air from the reservoir 4 to the brake cylinder 3. The valve 11 allows only a restricted flow and is seated by magnet 12 which is normally energized. The larger valve 14 is seated by a spring and is opened by a magnet 15 normally de-energized. Only the valve 11, therefore, is opened by an interruption of the current. Application of the drive can be effected by first opening the valve 11 and then, if necessary, the valve 14 or by opening only the valve 14. As shown in Fig. 2, both automatic and manual applications are obtained by a single valve controlled by two electro-magnets 50, 60 actuating an armature 40. The magnet 50 is normally energized and then holds the valve closed; it is opened to a limited extent when this magnet is de-energized, by the spring 17 acting against a second spring 20 on the air pressure and may be opened more fully by energizing the magnet 60.
