Title: Improvements in Artificial Legs.
Inventor: SAUZE EUGENE
IPC: A61F2/60
Filed: 1918-08-06
Abstract: 118,840. Sauze, E. Sept. 4, 1917, [Convention date]. Limbs, artificial.-A leg comprises a stumpsocket a connected to a knee member c by a pivot b and screw bolts d passing through arc-shaped slots e, which allow limited rotation of the parts. Plates fare interposed between the members a, c for adjusting the length of the limb. The lower leg i is pivotally connected by means of straps h and a pivot g mounted in the member c. A rod j is pivoted adjacent to the pivot g and extends down to the foot, where its end rests on a number of washers o arranged in a recess formed in a rubber pad n. Pressure transmitted by the rod j to the rod-pivot k, when weight is rested on the heel in standing, prevents the limb from bending. The compression of the pad n by the lower end of the rod j also straightens the leg after being bent in walking, this action being assisted by a cord m attached to an eye l on the rod j and connected to a harness on the shoulders. A more energetic operation of the cord m will prevent the leg from bending irrespective of pressure on the rod j. The foot p is connected to the leg by a ball q attached to a rod q<1> and received in a socket r connected to the foot by bolts t. A rubber pad v is interposed between the toe and the body of the foot and is covered by a strip x of leather, a leather head y beneath the foot serving as a hinge.
Patent GB-591802-A (GB)
Title: Improvements relating to switching means either for allowing a plurality of cyclically-operative thermionic systems to operate singly in a pre-determined order or for allowing the interrupted operation of only a specific one of them
IPC: G01S13/76
Filed: 1945-05-22
Abstract: 591,802. Radio signalling. FERRANTI, Ltd., TAYLOR, M. K., WILLIAMS, F. C., and CARTER, R. H. A. May 22, 1945, No. 12809. [Class 40 (v)] The invention is described in connection with responder apparatus on aircraft which is responsive to radar signals from long-range early-warning ground stations for the greater part of the time, and for a short time is responsive to short-range gun-laying stations. Once however the aircraft enters a gun-laying area, the apparatus is not switched back to be responsive to early warning signals until the aircraft leaves the gun-laying area. Fig. 2 (Prov.) shows the general arrangement comprising responder means x which responds only to signals from gun-laying stations, and responder y which responds to early-warning stations. Each responder comprises an aerial feeding a tuned circuit a<1>, a<11> the tuning of which is swept through a band of frequencies including the carrier of the desired pulsed exploring wave. When circuits a<1> or all are tuned to the appropriate frequencies the incoming pulses are received in a super-regenerator receiver b<1> or b<11> having a common quench oscillator c. The output from b<1> or b<11> is detected at d<1> or d<11> and amplified at e before being passed to a pulse widening network f<1> or f<11> which supplies an identifying characteristic to the pulses. The widened pulses are then passed to the transmitting valves of responders x or y to re-transmit each, received pulse in a widened, form. The output from e is also, fed through a rectifier g and D.C. amplifier h to a switch mechanism i which causes the alternative operation of receiver b<1> or b<11> and of circuit f<1> or f<11>. The switch mechanism i comprises a multi-pole change-over relay which is under the joint control of a continuously rotating cam and of the current through D.C. amplifier h. As normally a craft is outside the gun-laying areas for the greater part of the time, the cam is made so as to render the apparatus sensitive to the early warning stations for a large part of the time, and sensitive to gun-laying stations for short periods. Also D.C. amplifier h is biassed so as only to pass current on receipt of signals from gun-laying stations. When however the craft enters a gun-laying area, the D.C. amplifier h conducts so that at the next switch over, a hold-on circuit is completed, and the apparatus is not again made sensitive to early warning stations until the craft leaves the gun-laying area. Indicator lamps operated by movement of the change-overrelay, inform the pilot as to which area the craft is in. Specification 585,347 is referred to.

Title: Improvements in or relating to fluid-pressure traversing and locking mechanism for machine tools, more particularly wheel lathes
IPC: B23B5/28
Filed: 1939-04-29
Abstract: 528,166. Actuating machines; turning. URQUHART, LINDSAY & ROBERTSON ORCHAR, Ltd., and BUCHANAN, G. H. April 29, 1939, No. 12858. [Classes 83 (iii) and 83 (iv)] In a fluid-pressure actuated traversing and locking mechanism for movable machine-tool heads such as the loose headstock 1 of a wheel lathe has a double acting cylinder connected to the head locking means carried by the head and a control valve controlling the supply of fluid to the cylinder and locking means. The cylinder 2 is secured to the headstock and has a stationary piston whose rod is anchored at 6 to the bed. The headstock also carries a pump 8 driven by a motor 9 and supplying fluid to a line 16 connected to a valve 13 operated by a handle 14. From the valve, fluid may flow to either end of the cylinder 2 and also the locking means 11 consisting of cylinders 23 which move over stationary pistons 24 and have a flared extension 26 which operates toggles 27 to effect the clamping and unclamping. The valve handle 14 has neutral " traverse in " and " traverse out " positions and is associated with a motor control cam switch 15 which stops the motor when the handle is in " neutral " position. When the movement of the headstock is arrested by a stop, the subsequent pressure rise opens valve 17 and allows pressure fluid to pass to the clamping cylinders. When the clamping is completed, further pressure rise opens valve 18 and moves valve 13 axially so that a torsion spring 13a may return the valve to neutral position, the pump thus being stopped. Similarly when the valve is moved to " traverse out " position, the pressure build up causes first the unclamping of the head and then the return movement is effected. The pump 8 may also supply. pressure fluid to a work hoisting and lowering device. To stop the headstock without clamping a valve 22 may be provided in either or both of the " in " and out " circuits to byepass pressure fluid back to the tank. Lamps 20, 21 may be arranged to indicate operation or non operation of the clamping mechanism.

Title: Garment pressing machine
IPC: D06F71/06
Filed: 1948-05-11
Abstract: 660,264. Ironing-presses. BISHOP CO., G. H. May 11, 1948 [July 26, 1947], No. 12909/48. Class 138 (ii). A garment-pressing machine includes a single movable heated head 18 and at least one buck 19 vertically adjustable to correspond to the stroke of the head, the head being movable toward or away from the buck in a straight line vertical movement by means of a long stroke fluid pressure cylinder 13, and piston 16, automatic return means for raising the head when the pressure in the cylinder is released, and a manual control of the fluid pressure to operate the head in long or short strokes, the head being widely spaced from the buck when in its uppermost position for convenience and safety. The head 18 is urged downwardly against the buck 19 when fluid under pressure is admitted to the cylinder 13 by depressing a foot pedal 39. This pedal may depress a piston-rod 38 in a cylinder 37 containing the pressure fluid or alternatively the pedal may actuate a three-way valve to allow compressed air to be supplied to the cylinder 13 from an external source. Two long coil springs 20 mounted one on each side of and outside the cylinder return the head to its raised position when the fluid pressure is released. This disposition of the springs preserves the head in rotational alignment with the buck. The head may be electrically heated by elements supplied through a coiled cable 24. The fluid under pressure is supplied to the cylinder 13 through a pipe 36 in a hollow standard 10, the top of the pipe 36 being sufficiently bendable to permit slight vertical adjustment of the cylinder 13 in a clamp 14. The head 18 may be slightly dished on top (at 45) or have a peripheral rim to catch any oil or pressure fluid escaping from the cylinder. It may also be provided with a thin metal grid plate, Figs. 6 and 7 (not shown), having fine perforations punched therein close together over its entire surface, and a spring edge making it a snap-on device. The punching protuberances on the inside slightly space the grid from the head. The buck may be adjustably supported on the standard 10 and provided with a table 28. In, a modification (Fig. 4) a plurality of bucks 51, 52, &c. may be mounted on circular table 50 mounted on a sleeve 56 for rotational movement about the standard 10, the bucks themselves being of varying sizes. Proper registration of each buck with the head may be ensured by means of a bearing washer 58 secured to the lower end of the sleeve 56 and provided with appropriately spaced radial V-shaped indentations registering with similar indentations on a fixed washer 59.
