Title: Artificial limb
IPC: A61F2/64
Filed: 1939-11-06
Abstract: 535,320. Artificial legs. WOODALL, C. Nov. 6, 1939, No. 29463. [Class 81 (ii)] [Also in Group XXV] An artificial knee joint comprises a member 12 hinged to a thigh socket 11 and a shank member 14 by means of pintles 25, 32. Straps 36 lined with friction material 40 press against the pintles and their friction may be varied by adjusting screws 42. A wedge 85 is provided for rotation into a position between a shoulder 57 of the knee-member and an abutment 59. The leg is thus not able to be straightened completely, the weight of the body being taken on the toe for running, climbing or dancing.

Title: Automatic control system
IPC: G05B13/02
Filed: 1971-06-23
Abstract: 1358590 Automatic control systems ADAPTRONICS Inc 23 June 1971 [25 June 1970] 29513/71 Heading G3R The gain of an automatic control system is adjusted according to a factor derived from an error signal. The error signal e is applied to a device F 4  (e) in which the error and its first or higher order derivatives are obtained and the square root of the sum of their squares is derived, the result r being used to control the gain by which a signal u' is amplified. The signal u' is obtained by adding ep, which is equal to e plus its first derivative e or e<SP>2</SP>, to f 2 , which is a function of associated variables Y such as actuator positions and rates, and detecting the sign of the sum in F 3  (ep'). This latter device also contains a limiter, to prevent strain on the system when the sign changes. Thus u' is unity with the appropriate sign. The product GU' is added to its integral to produce the controlling signal u, Gu' being limited at F 5  Gu' before integration. The device G (r) for varying the gain in response to r may also have a limiting action and/or it may produce a minimum G when r is zero.

Title: An improved cementing process and apparatus therefore
IPC: A43D25/06
Filed: 1936-10-30
Abstract: <PICT:0483832/IV/1> <PICT:0483832/IV/2> In joining parts by means of an adhesive which is thermoplastic and may be dissolved in volatile solvents, the adhesive used has higher hysteresis characteristics than the materials of the parts to be joined, and is softened by heating by means of an electric field of frequency at least 100,000 cycles per second, the parts to be joined being forced together under pressure.  The adhesive may be a natural or synthetic resin, or a cellulose derivative, or mixtures thereof, with or without plasticizers or volatile solvents, and conducting substances such as metal filings, carbon, or acids or salts may be included.  The electric field may be applied by means of an electric or magnetic coil, but preferably by means of metal condenser plates connected to a source of high-frequency current.  The process may be applied to the making of shoes, heavy leather belting, safety glass, plywood, and wall-board having a wood vencer on a cement-asbestos base.  The invention also comprises apparatus comprising a yielding bed, an electrical conductor embedded in the surface thereof, a firm body having a similar conductor, means for pressing the conductors against the opposite sides of the parts to be joined, and means for supplying high-frequency current to the conductors.  In the form shown, a shoe last 1 carries a shoe upper having a welt 4 to which a sole 6 is to be united by films of adhesive 5.  The shoe and upper are held together by members 2 and a pressure bag 9, and conductors 10 connect condenser plates 7 and 8 to a source of high-frequency current.  The adhesive used may be a toluene solution of the reaction product of dichlorodiethyl ether and diphenylol-3.5-dimethylcyclohexane, or a natural or another synthetic resin or a cellulose derivative, or mixtures thereof, with softeners and solvents.  The hysteresis values of the adhesive may be increased by incorporating therein metal filings, carbon, or small amounts of electrolytes, e.g. acids and salts.
Patent GB-750255-A (GB)
Title: Improvements in or relating to record card controlled machines
Inventor: HOLDSWORTH ALAN SYDNEY
Filed: 1953-10-26
Abstract: 750,255. Record-controlled printing-machines. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. Oct. 4, 1954 [Oct. 26, 1953], No. 29571/53. Class 100 (4). [Also in Group VIII] A printing stamp for printing indications on a series of intermittently-fed instruction cards IC, which are also perforated at the same time under the control of pattern cards (see Group VIII), comprises a number of manually - settable printing- wheels 71 in a frame 70 which is supported from the ends of a pair of arms 75, 76 pivoted at 77 to the outer end of an arm 78 secured to a sleeve 79 on a shaft 80. A pin 81 connecting the two arms 75, 76 is urged by springs 82 into contact with the upper edge of the arm 78. The frame 70 has an upstanding screw-threaded stud 72 which passes through a bar 88 for limiting the upward movement of the frame and is engaged by a nut 73 having spindles 74 located in slots in the arms 75, 76. Rocking of the sleeve 79 and arm 78 to raise the frame is effected by a cam 87 rotating with a drive-shaft 20 and operative through an arm 85, link 84 and arm 83 secured to the sleeve; the arms 75, 76 are then raised until the frame 70 is stopped by the bar 88, whereupon the springs 82 yield and become loaded by the continued movement of the arm 78. The arms are then held in this position, despite the continued rotation of the cam 87, by a spring-pressed lever 91 which engages under the outer end of the arm 83 until a second cam 99 on the shaft 20 operating through an arm 87 and slidable link 95 rocks the lever 91 to release the arm 83 and permit the stamp to descend, the loading applied to the springs 82 ensuring the continued descent of the stamp for printing; the springs then recover to permit the feed of the next card into position. To render the printing device inoperative, the stop-bar 88 is carried by end arms 100 which can swing about spindles 101 coaxial with the pins 74. Normally the bar is locked in printing position by a latch 102 co-operating with an arm 100, but on release of this latch (by a manually-operable slide 106 acting through a bell-crank 104), the bar and stamp can be swung about the axes of the spindles 74, 101. Alternatively, the device may be disabled by hand-operated mechanism acting upon the spindle of the arms 75, 76 to restrain them and the stamp in raised position. The instruction cards, which are separable from each other along weakened lines, are fed from a roll to the printing position by a pair of pin-wheels 39 engaging marginal holes in the cards and driven by a shaft 40 which is rotated in steps by ratchet gearing from a gear 44 rotatable on the shaft and meshing with a sector 45. The sector is rocked intermittently from a cam 50 on the shaft 20 through an arm 47 and link 46; a pin 52 on a spring-supported lever 53 engages a detent wheel 51 on the shaft 40 to prevent reverse movement of the latter.

A washing and drying-machine includes a drum 17 at the bottom of which are two impellers 16, and the drum is provided with a hollow bottom containing gears 14 and 15 which connect a shaft 9 driven by an electric motor 6 to the impellers. A bushing connected to the bottom of the drum may be caused to grip shaft 9 by spring pressure. Under these conditions the drum 17 is caused to rotate and the impellers do not move relatively to the drum. A substantial part of the water in drum 17 is then discharged by centrifugal force through the perforations in its wall. The bottom of the drum is provided with a raised portion 29 to facilitate circulation.

Abstract: The invention comprises 1,2,4-oxadiazoles of formula: <FORM:0942883/C2/1> in which R is vinyl or isopropenyl and R1 is hydrogen or a C1-C4 alkyl group.  The new compounds may be formed by heating a corresponding 3-acyloxyalkyl-1,2,4-oxadiazole.  The 3-acyloxyalkyl-1,2,4-oxadiazoles may be obtained by reacting a 2-hydroxy alkaneamidoxime or a 3-hydroxyalkaneamidoxime with a cyclising agent to form a 3-hydroxyalkyl-1,2,4 oxadiazole which is acylated.  These latter steps may be carried out in a single operation by using a monocarboxylic acid anhydride as the cyclisation reagent.  Alternatively formamide or s-triazine is used as cyclising agent and the resulting hydroxy compound acylated. 2-0Hydroxyisobutyramidoxime and 3-hydroxy propionamidoxine used as standing materials are prepared by reacting acetone cyanhydrin and ethylene cyanohydrin respectively with hydroxylamines.ALSO:1,2,4-Oxadiazoles of formula: <FORM:0942883/C3/1> in which R is vinyl or isopropenyl and R1 is hydrogen or a C1-C4 alkyl group are polymerized, e.g. in the presence of azobisisobutyronitrile.
