Title: Rotatable assembly including two vaned wheels mounted on a common shaft
IPC: F02B37/00
Filed: 1973-04-06
Abstract: 1430864 Shaft couplings W E WOOLLENWEBER 6 April 1973 16520/73 Heading F2U [Also in Division F1] The invention relates to a rotatable assembly comprising two vaned wheels mounted on a common shaft and is described with reference to a turbine compressor assembly such as a turbo-charger for an I.C. engine which comprises a turbine wheel 14 and a compressor wheel 18 mounted on a common shaft 22. The shaft 22 is formed integrally with the turbine wheel 14, the other end of the shaft having a threaded portion 56 which engages a threaded core in the hub of the compressor wheel. A sleeve 66 is disposed around the shaft between the two wheels whereby the shaft is placed in tension by the screwed connection. The shaft is provided also with an unthreaded extension 60 which engages in an unthreaded extension of the bore in the hub of the compressor wheel for location purposes. A further sleeve 68 is disposed round the sleeve 66 and forms the inner race of a pair of ball-bearings. The shaft 22 is formed with a portion 64 of reduced diameter so as to reduce heat conduction along the shaft.

Title: An improved articulated peg leg
IPC: A61F2/60
Filed: 1919-07-02
Abstract: 144,887. Purchase, W. July 2, 1919. No Patent granted (Sealing fee not paid). Limbs, artificial.-In appliances of the type in which the relative longitudinal movement of the two parts of a leg locks the knee-joint when the weight of the wearer is placed on the leg, the locking is effected by a convex part f at the bottom of the thigh piece a coming in contact with a rubber pad o at the top of a peg portion b. A sleeve is connected by arms g to the end of the knee bolt h. Screws l pass through the sleeve e into opposite grooves j, m in the portion b, and can abut against a spring n or rubber block k which serve to cushion the longitudinal movement which is limited by screws c moving in slots d. Rotary movement of the portion b is limited by a shoulder i on the portion a abutting against the arms g. The leg may be held in an extended condition or given a limited movement, by means of a thong p secured at one end to the thigh portion a and passing thence through a hole r in the portion b, back through a hole s to a cleat r, which serves to engage one of the knots u<1>, u<2>, u<3> as desired. 'An elastic strap v connected at its upper end to the upper ends of a pair of leather straps x is used to attach the limb to the body.

Filed: 1960-05-10
Abstract: 985,312. Inverting. TEXAS INSTRUMENTS Ltd. May 10, 1961 [May 10, 1960], No. 16526/60. Heading H2F. [Also in Division H3] An inverter or amplifier comprises a pair of silicon controlled rectifiers SCR1,: SCR2 (or combinations of transistors which operate analogously to silicon controlled rectifiers) having anode resistors R1, R2 and connected in series between positive and negative D.C. terminals P, N, the junction A being connected to earth O through a load S and the two rectifiers being controlled to be conductive alternately so that A.C. flows in the load. The control circuit includes transistors VT1, VT2, connected in series with resistors R8, R10, between terminals P and N, and rendered conductive by a square wave signal applied to a transformer T1. On the positive half cycle transistor VT2 and rectifier SCR1 are conducting. On the next negative half cycle transistor VT2 is switched off and VT1 is switched on. The potential at point B rises to the level P and this is transferred through capacitor C5 to the point A switching off SCR1 whose anode potential rises providing, through a delay circuit R3, C2, a firing signal for SCR2. The operation is reversed for the next half cycle. The load may be inductive, e.g. a motor winding, or resistive when the arrangement may be used as a linear amplifier. The silicon controlled rectifiers may be replaced by pairs of complementary PNP,NPN transistors.

Title: A typewriter adapted to write ligatures
IPC: B41J3/01
Filed: 1952-07-03
Abstract: 728,149. Typewriters. OLYMPIA WERKE WEST GES. July 3, 1952 [July 3, 1951; Sept. 29, 1951], No. 16743/52. Class 100 (4). Back-spacing mechanism; ; stroke adjustment.-A typewriter is provided with a device in addition to the conventional back-spacing key so that ligatures may be printed; the device comprises an additional key 4 pivotally mounted on the back-spacing key and effects a shorter back-spacing step. The amount of back-spacing may be controlled by a screw on an eccentric disc mounted on the key 4 or to coact therewith. To avoid a subsequent letter being typed too close to the ligature, the ligature key is coupled to the space-bar 12 so that when printing of the ligature is completed a letter-space is automatically effected. In machines where two different letter-spaces can be effected it is coupled to the larger. As shown in Fig. 5, the ligature key 4 when depressed causes a turnedout lug 10 thereon to engage a lever 13 that rotates a space-bar shaft 11 which through an intermediate lever 14 and link 15 engages the rocker 16 of the escapement mechanism which only when released effects the letter-spacing. The lever 13 is locked in the downward position by a notch 24 on a latch 20 and is not released until the end of the return movement of the ligature key when the end 23 thereof engages the upper end 22 of the latch pivoting it clockwise and releasing the lever 13 from the notch 24. The release of the lever 13 permits a letter-spacing movement.

Abstract: 680,048. Straightening; winding. NATIONAL MACHINERY CO. July 5, 1950 [July 9, 1949], No. 16777/50. Class 83 (iv). In an apparatus for straightening the end portion of coiled stock for feeding to a metal working machine the end of the stock is clamped to a hinged anvil and the coil moved to unwind a portion of stock and the anvil is tilted to straighten the stock. The coil is then swung into alignment with clamps which position the stock for entry into a metal-working machine. The coil W is carried on a drum 27 with collapsable arms 23 on a shaft 22 mounted on a turntable 20 on a carriage 18 traversed by a hydraulic cylinder 13. A clamping device 31 comprises an anvil member 32, slidable along a shaft 34 for alignment purposes, carrying a clamping jaw 42 operated by a hydraulic cylinder 36 and toggle mechanism to secure the stock to the anvil. After the stock is secured the carriage 18 is moved to the left, Fig. 1, to unwind a portion of stock and the anvil is tilted by cylinder 37 to straighten the stock. The clamp 42 is then released and the turntable swung 180 degrees by releasing a pin 28 to align the straight end of the stock with a clamp. This clamp, Fig. 2 (not shown), is actuated by a jack powered by a foot pump to secure the end of the stock and is adjusted for height by a screw and transversely on a horizontal pin by worm gearing to align the stock with the metal-working machine. The hydraulic cylinders may be controlled from a valve panel.

Abstract: 792,910. Turbines. DE HAVILLAND ENGINE CO., Ltd. May 19, 1954 [June 19, 1953], No. 17119/53. Class 110 (3). A reaction turbine comprises a hollow rotor, means for supplying to the rotor at or near its axis of rotation a liquid which can be decomposed catalytically to produce gaseous decomposition products, pervious catalytic material within the hollow interior of the rotor for decomposing the liquid, and discharge nozzles at or near the periphery of the rotor directed substantially tangentially and through which the gaseous decomposition products are discharged to impart a driving torque to the rotor. In Fig. 1 the rotor comprises a flange 14 formed on one end of a shaft 11 and a disc 15 bolted to this flange and provided with perforated annular projections 16, 17. The space between projections 16, 17 is filled with catalyst material 18, e.g. silver gauze, capable of decomposing concentrated hydrogen peroxide. A rod 22, axially movable within a supply pipe 20, is provided with a metering land 23 which co-operates with a port 24 to control the supply of hydrogen peroxide to the interior of the rotor. In operation hydrogen peroxide is supplied to end chamber 21 and passes through pipe 20 and port 24 to the interior of the rotor where it is decomposed by the catalyst 18 into steam and oxygen which produces a reaction on the nozzles 28 tending to rotate the rotor. Control of the turbine speed is exercised by adjusting the metering rod 22 and thus controlling the supply of hydrogen peroxide; this may be effected by a governor driven by the turbine controlling the pressure of a fluid contained in a bellows 29. The exhaust from the turbine may be allowed to escape, or when the turbine forms part of a rocket motor the exhaust may be collected in a discharge duct and fed into the combustion chamber of the rocket motor where its oxygen content can be used for the combustion of some of the fuel.
