Title: Improvements in or relating to automatic stopping mechanism for wire weaving looms
IPC: D03D41/00
Filed: 1928-07-07
Abstract: 294,645. Vereinigte Stahlwerke Akt.- Ges., (Assignees of Merse, W.). July 29, 1927, [Convention date]. Stop-motions, warp and weft.-In a wireweaving loom, relays wider than the control of the warp and weft are energized in such a manner that if either the warp or the weft breaks, one of them effects stoppage of the loom by mechanical means. The weft normally makes contact with pairs of stretched insulated wires g, while the warps are normally free from insulated contact bars p. A disc a on the crankshaft has slip contacts h adapted, just before or after the beat-up, to complete an electric circuit comprising the wires g, a battery b, a coil I, the framework s of the loom, and the weft, an armature i thereby being attracted. A little later a further contact completes a circuit through a coil II which fails to attract the armature already attracted to the coil I. If, however, the weft is broken, the coil I is not energized and the armature i is attracted to the coil II, whereby a circuit is completed through an electromagnet r by a contact k to stop the loom. When a warp wire breaks it makes contact with one of the bars p to complete a circuit through the electromagnet r, the armature o of which effects the stoppage of the loom through mechanical devices. The battery b or a separate battery l may be employed for energizing the magnet r.

Title: Improvements relating to electrolytic removal of metal
Inventor: WILKINSON BERNARD HALL
IPC: B23H3/04
Filed: 1960-06-03
Abstract: 937,286. Electrolytic machining. ROLLSROYCE Ltd. May 31, 1961 [June 3, 1960 (2)], No. 19828/60 (Divided out of 937,287) and 19575/60. Class 41. Metal is removed from a workpiece, electrolytically, by disposing a solid or hollow electrode cathode adjacent the anode workpiece leaving a gap of 0.005 to 0.04 inch, and feeding electrolyte through the gap at the rate of about 2 gallons per minute per sq. inch of workpiece surface. The metal is removed entirely by electrolytic action, and the gap is maintained constant. The voltage applied is about 12 v., and C.D. is in the range 30 to 150 A.S.I., preferably about 40, which with the high flow rate of electrolyte gives a fine finish on turbine blades. A workpiece 12, Fig. 1, is clamped on a frame 11 mounted within a tank 11 and spaced below a hollow electrode 15 fed with electrolyte through a shoot 16. The electrode is mounted on a rod 18 which is raised or lowered by gearing 20, 21, motor 22 connected to a servo control unit 31 which maintains the gap constant. The electrolyte e.g. salt solution, is fed by a pump 24 to the hollow electrode, and flows out from the tank 10 through a filter 26. To form a concave surface a cylindrical electrode 15, Fig. 2, is used with a shaped electrolyte delivery shoot 16. In another form for shaping turbine blades, a hollow electrode, Fig. 6, is provided on the surface with slots having therein metal plates inserted between plates of plastic leaving the edges of the metal plates 35 exposed to act as electrodes. The electrolyte enters at 34 and flows out between the metal plates, which are vibrated to etch the total surfaces. Electrolyte delivery tubes of other shapes are also illustrated.

Abstract: 1,069,360. Windscreen wipers. GENERAL MOTORS CORPORATION. May 5, 1966 [May 6, 1965], No. 19847/66: Heading A4F. [Also in Division H2] A windscreen wiper spindle 26 (Fig. 3, not shown) is driven through a reduction gearing (38) and bevel gears (40, 42) by a reversible direct current motor (36) controlled by a reversing switch 48 (Fig. 2, not shown) actuated by a pin 54 extending from the gear (40) through superposed arcuate slots 84, 86 in cam members 56, 58. During operation of the wiper the members 56, 58 are latched together by a spring latch 70 carrying a magnetic element 74 and held in its latching position by an electromagnet (44, 46). Towards the end of a wiper stroke the pin 54 normally engages an end of the slot 86, which is shorter than the slot 84, and rotates both members 56, 58 so that an arm 60 or 62 on the member 56 actuates a member 64 or 66 to operate the reversing switch. When the wiper motor control switch (130) is moved to its "off" position, however, the electromagnet (44, 46) is deenergized to release the latch 70 so that the pin 54 moves the member 58 relatively to the member 56 to align the ends 94, 88 of the slots 84, 86 before moving the member 56 to actuate the reversing switch. The wiper stroke is thereby extended so that the wiper blade is parked in a posiion beyond the normal wiping arc. The motor armature is short-circuited to brake and stop the motor when the reversing switch is so actuated. The wiper may be mounted to clean the rear window 14 (Fig. 1, not show) of a motor vehicle.

Title: Air compressor oil control system
Inventor: CLARK RICHARD BLAIR
IPC: F04C29/02
Filed: 1968-05-01
Abstract: 1,207,207. Lubricating. CATERPILLAR TRACTOR CO. 1 May, 1968, No. 20566/68. Heading F2A. A lubricant control system effects the supply of lubricant at selective rates to an enginedriven compressor so that the rate of lubricant supplied corresponds to the speed of the compressor. In an embodiment, an engine 11 drives a compressor 13 which supplies compressed air to a receiver 17, via an outlet 16, a check valve 19 and a pipe 18. Compressed air is supplied from the receiver 17 to a point of application (not shown) via a Venturi 28 and an outlet 21. Lubricant is circulated by means of a pump 22 and is delivered to an inlet 24 in the compressor 13. The lubricant circuit comprises flow regulator means 63, a cooler 64 and a junction 54; the latter communicating with lubricant collected in the receiver 17 or with lubricant collected in a sump 51 in a by-pass 39, according to the position of solenoid-actuated valves 43 and 61. In use, when compressed air is withdrawn from the outlet 21, the compressor is operating at compressing speed, and increased air pressure in a manifold 12 of the engine 11 acts against a diaphragm 48 so as to activate a switch 44. The valve 43 is closed so that lubricant cannot circulate through the by-pass 39 and the lubricant circuit is completed through the junction 54 and the receiver 27. Increased air pressure in the manifold 12 also actuates control means 33, 34 and 63 to allow an increased flow of lubricant to the compressor. When compressedair withdrawal from the outlet 20 ceases, the switch 44 closes, the solenoid valves 43, 61 are returned so as to close the lubricant circuit and re-open the by-pass 39, and the control means 33, 34 and 64 reduce the flow of lubricant to the compressor which is now driven at idling speed. The speed of the engine 11 may be regulated by means of pressure-actuated control means 29 which is connected to the Venturi 28 by means of a pipe 27 and to a governor 26 by means of a member 32.
