IPC: A61F2/58
Filed: 1930-02-03
Abstract: 347,325. Artificial limb joints. BLATCHFORD, C. D. W. and BLATCHFORD, W. A. D., 90, Clapham Road, Stockwell, London. Feb. 3, 1930, No. 3663. [Class 81 (i).] An elbow or knee joint for artificial limbs of the type in which the lower arm or leg member is movable into various adjusted positions in a vertical plane and locked or released therefrom, comprises upper and lower limb members connected by a transverse shaft divided into two portions adapted to telescope one within the other, means associated with one portion for rotating the shaft and moving one limb part relative to the other, and locking means comprising a bolt or pin, to releasably lock said limb part. As applied to an elbow joint, the ring member 1, rotatably mounted in or on the upper arm bucket 2 are adapted to be locked in any desired position, has lugs 3, 4 provided with bearings 5, 6 for the shaft 7, on the angular or squared ends 8 of which straps 9, carrying the forearm, are mounted. The shaft is divided into two portions 15, 16, connected by a cross-pin 20, the portion 16 being formed with a quadrant or disc 17 having apertures to receive a locking-bolt or the like 19. A pin or extension 21, provided on an enlarged portion of the shaft 7, engages a rubber or other stop 22 on the lug 3 and limits the forearm movement. The lug 4 is extended to form a casing 23. A tubular bearing 24 for the bolt or pin 19 is provided in this casing. The grooved sector or quadrant 25 provided on the sector 17 is connected to an appendage 26, passing over a roller 27, by which the shaft 7 can be rotated.. A closure screw or cap 28 for the casing 23 provides an abutment for the spring 29 which bears against the base of a recess 30 in the bolt 19. A cam 34, secured on a rotatable shaft 35, engages a lug 31 on the bolt as described in copending application 344,429, and on the other end of the shaft 35 is rotatably mounted the casing of a free-wheel clutch or the like of the type described in copending application 344,430, in which a pair of spring-pressed balls or the like contact with the shaft, and are arranged to clutch the same when the casing is moved by means of an appendage against the action of a coiled spring, secured at its ends to the free-wheel casing and to the casing 23 respectively, and to declutch when the appendage is released. The arrangement is such that the locking bolt 19 is only moved out of locking position when the cam moves through substantially 90‹, and returns to its locked position if the rotation is less. A casing 41 detachably secured to the lugs 3, 4 may be fitted.

Title: Improvements in and relating to textile yarn twisting machines
Inventor: HILL MOORE
IPC: D01H1/10
Filed: 1963-01-29
Abstract: A two-for-one outflow twisting machine has a non-rotating carrier for the let-off means and two flyers which are mounted on parallel axes at opposite ends of the carrier and which are positively driven at equal speeds; the let-off means comprises two or more bobbin spindles, the axes of which are offset from each other and at right angles to the axes of the flyers, while separate means are associated with each bobbin to tension the material drawn off each bobbin.  In Fig. 1 not shown, flyers (2, 4) are carried by spindles (20, 32) rotated by toothed pulleys (26, 38) driven by toothed belts (42, 44). The carrier (18) is rotatably mounted on the flyer spindles which are parallel but not coaxial to keep the carrier stationary.  The bobbins are on spindles (46, 48) which are perpendicular to the flyer-spindles for easy removal of the bobbins.  Yarns which may be single-or multi-ends, are pulled off sideways by haul pulleys, not shown, taking the path shown through the flyer-spindles which have radial passages (52, 54).  The yarns are kept at constant tension by drag-members (64) each comprising two inclined plates bearing on the package and pivoted part way along an arm (58 Fig. 2 not shown) which is pivoted at one end and carries a weight at the other.  In Fig. 3 (not shown), the flyers are mounted horizontally and coaxially, and the bobbins vertically; the carrier (84) is rotatably mounted on one, (86), of the flyer spindles which is suitably elongated, and is prevented from rotating by its weight and that of the bobbins, their combined centre of gravity being offset from the axis (86).  The tension of the yarn is maintained by a brake beneath each bobbin comprising p  plates (116, 112) fixed respectively to the carriage and the base of the bobbin with friction pads (118) between them.  As the yarn is drawn off the bobbin rotates and one plate rotates relatively to the other overcoming the friction of the pads; the weight of the bobbin decreases and so does the friction but the yarn unwinds from a decreasing diameter so maintaining the tension constant. The working-tension may be adjusted by varying the load on the plates or the composition of the pads.  The flyers may be discs or tubes.

Title: Improvements in and relating to systems of regulation for electric circuits
IPC: H02P9/24
Filed: 1920-02-06
Abstract: 162,118. British Thomson - Houston Co., Ltd., (General Electric Co.). Feb. 6, 1920. Regulation, automatic systems and apparatus for.-Circuits are automatically regulated by means of a rotary converter having its direct current side connected to the circuit to be regulated and its alternating current side connected to devices for imposing variable reactance. The invention is described in application to the field of a generator for the purpose of maintaining constant voltage and with the employment of reactance coils, the reactance of which is controlled by direct current magnetizing windings. Fig. 1 is a diagram of one arrangement for regulating the voltage of a direct current generator 2 having a shunt field 4, by means of a rotary converter 7, a variable reactance device 10, and a vibratory variable resistance device 22. By means of the device 22, voltage variations affect the amount of current flowing through direct current magnetizing coils 14, 14<1> of the device 10, and thus impose a variable reactance upon alternating current coils 13, 13<1> connected to one side of the rotary converter 7, the other side of which is connected to the shunt field circuit of the generator. The current flowing through the shunt field is thus increased or diminished, and accordingly the voltage of the generator rises or falls to compensate for variations on the mains. In a modification for regulating the voltage of an alternating current generator, the arrangement of Fig. 1 is applied to the direct current exciter machine. In addition the vibratory resistance controller is furnished with an anti-hunting winding and a differential winding adapted to keep out the resistance in proportion to the strength of current in the exciter field. In a further modification for regulating a number of alternating current generators connected to exciter bus-bars fed by one or more exciter machines, the arrangement described above is applied to the exciter machines in common, and the responsive vibratory device, instead of acting on a resistance directly, acts as a, relay to bring a resistance controlling vibrator into and out of action.

Abstract: 702,674. Sawtooth generating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Jan. 31, 1952 [Feb. 16, 1951], No. 3761/51. Class 40 (6). [Also in Group XXXV] A scanning oscillator for television and like purposes comprises a valve 7 back-coupled at 8 to operate as a blocking oscillator, a saw-tooth wave (s) being generated across the condenser 5 by charging it through a resistor 6 and discharging it through the valve during its short conductive intervals. During the discharge a condenser 13 connected between cathode and earth is charged rapidly and discharges through a shunt resistor 12 and a shunt circuit comprising resistors 14, 15, and condenser 16. The shunt circuit 14 ... 16 operates as an integrator and contributes a parabolic component to the wave (a), thus steepening the upper part of the short flanks of that wave. The modified periodic waveform (a) is taken off from the junction 14, 15 and is led to the grid of a control valve 4 where it is superposed on the incoming sync pulses 1 of constant amplitude, to produce resultant pulses (b). Amplified pulses at the anode of the valve are smoothed by condenser 21 and network 22, 23 and the smoothed voltage is applied to the grid of the blocking oscillator 7 to correct its frequency. In a modified circuit the valves 4, 7 have a common earthed cathode, and the junction of the elements 12, 13, 14 is connected to a point in the scanning circuit from which current pulses are received. The potential-divider 17, 18 is connected to a negative potential source, and the junction, instead of being connected to the control valve cathode, is connected by a large resistance to the lower end of the resistance 3.

Abstract: 1276292 Gas cushion vehicles HOVERCRAFT DEVELOPMENT Ltd 27 May 1969 [26 Feb., 1968] 4194/68 Heading B7K In a gas cushion vehicle the gas-cushion is divided into compartments 3a, 3b so that initially the vehicle is supported by cushion gas which is supplied by the fan units 5, 6 and when the vehicle has passed "hump" speed the fan unit 5 is shut down, the compartment 3a now being at atmospheric pressure, and the fan units 6 are speeded up to support the vehicle by just the outer compartments 3b. The front and rear of the compartments 3a, 3b are bounded by flexible skirts (not shown). The rear skirts may be made retractable so that air can escape beneath the skirts in addition to flowing through the ducts associated with the fans 5, 6 should the waves produce a "piston" action within the compartments 3a, 3b. In another embodiment Fig. 2, the fan units 25 supply both the compartments 23a, 23b. The cushion space is bounded except for the portion between the rear ends of the wall structures 24, by a flexible skirt 22 of inflatable form with its lower end comprised of flexible wall members 39 of the form disclosed in Specification 1,043,351. Tie cords 41 connect the inner ends 40 to the vehicle body 38. The rear end of the compartment 23a is bounded by a skirt 2, Fig. 3 (not shown), of the form disclosed in Specification 1,056,267, and is inflated by way of a duct (27). After "hump" speed has been reached the skirt 26 is deflated allowing cushion air to escape from the central compartment 23a thus causing the vehicle to sink. The wall structures 24 dip into the water and isolate the outer compartments 23b on which the vehicle is supported at a higher pressure. Since cushion pressure is related to the area of the cushion, pressure changes may be moderated by lateral deflection of the flexible skirt 22, Fig. 6 (not shown). The cushion of the vehicle may be divided into more than three compartments, as well as only two compartments, provided in this case that one surrounded the other to provide a symmetrical distribution about the centre of gravity. Also the reverse arrangement to venting the compartments may be employed.
