Title: Improvements relating to textile flyer frames
Inventor: FRANCE JOSEPH
IPC: D01H1/00
Filed: 1959-03-09
Abstract: 879,179. Clutch control stopping in predetermined positions. T.M.M. (RESEARCH) Ltd. March 8, 1960 [March 9, 1959], No. 8067/59. Class 80 (2). [Also in Group IX] A push-button control for the clutch CL of a textile flyer frame has automatic inching means for bringing the flyer to rest in predetermined positions which comprises an intermittently acting relay TA which, when the machine is stopped by opening a push-button controlled switch CLR, provides pulses to the clutch CL to inch the flyer frame to the predetermined position. With the switch CLR closed and the machine operating a switch S1 on the flyer spindle is closed for one-eighth of each revolution during which a relay TB is energized and a condenser C1 charged, the latter maintaining the relay energized whilst the switch S1 is open. Energization of the relay TB trips a switch TB1 to energize a relay TC and.charge a condenser C2. which relay closes a switch TC1. When the machine stops with the switch S 1 open, the relay TB is de-energized and the switch TB1 changes to the position shown whilst the condenser C2 maintains the relay TC energized and switch TC1 closed for a predetermined time (e.g. 20 seconds). The relay TA is energized through switches TB1, TC1, TA1 which trips the latter and closes a switch TA2 to complete a circuit to the clutch CL and restart the machine. The relay TA is deenergized after a time lag determined by the values of a condenser C3 and a parallel variable resistor R5 and the switches TA2, TA1 are opened and reset respectively, whereupon the relay TA is re-energized after a further time lag dependent upon the values of the condenser C3 and resistor R3, and the machine consequently restarted. The intermittent action of the machine is maintained until the flyer shaft reaches its predetermined position and closes the switch S1 to energize the relay TB which opens a switch TB2 in the clutch circuit. If the switch S 1 is still open after 20 seconds, the relay TC is de-energized and opens the switch TC1 to stop the intermittent action of the relay TA. The intermittent action may be overridden by opening a switch S2. More than one predetermined stopping position may be provided by additional switches S1. In the Figure accompanying the Complete Specification (not shown) the relay TC is connected across the clutch winding and energized therefrom and the intermittently acting relay is replaced by two such relays, one controlling the length of the clutch energizing pulses whilst the other controls the time between the pulses.

[Class 39 (i).] A tube, particularly a lamp having a filling of difficultly vaporizable metal and a rare gas, is composed of three interconnected limbs the axes of which lie along the edges of a prism and which are spaced by distances less than twice their diameter. Each limb contains an incandescent electrode. In one form, Fig. 2, the interconnected limbs 1, 2, 3 are such that their axes lie on an equiangular prism. The tube is surrounded by a double walled evacuated vessel 6. The diameter of each limb may be 20 mms. and the limbs are then spaced a few mms. apart. The filling may consist of sodium, lithium, potassium, rubidium, magnesium, zinc or cadmium, and is preferably of a metal the visible radiations of which consist partly of resonance rays, in order that the limb through which no discharge current is passing at any time may be excited to radiation by the radiation from the other limbs.

Title: Improvements in or relating to shock absorbing suspension devices for vehicles
IPC: F16F9/06
Filed: 1941-07-14
Abstract: 548,959. Shock absorbers. RIBBESFORD CO., Ltd., AUTOMOTIVE PRODUCTS CO., Ltd., and THORNHILL, P. W. July 14, 1941, No. 8885. Addition to 542,142. [Class 108 (iii)] The hydraulic shock absorbing and pneumatic suspension device for a vehicle according to the parent Specification is provided with a damping valve of smaller area than its control piston which is controlled by fluctuations of internal pressure so as to limit the valve opening during recoil occuring after either extension or compression. The upper of the two telescopic cylinders 14, 10 carries a throttle valve 20 and a control piston 32. The valve consists of a disc 26 movable relatively to the annular member 21 so as to control flow of liquid between the working cylinder 42 and the pressure chamber 40 which contains both liquid and gas. The disc 26 is approximately half the area of the member 21. The control piston 32 is movable under the control of springs 36, 37 between a collar 30 on the stem 25 of the disc 26 and a collar 35 slidable on stem 25 and abutting against the stem 24 of annular member 21. The movement of the assembly is limited by the end valve spindle 25 abutting the end of cylinder 14 and by annular member 21 engaging lugs 23 on cylinder 14. When stationary, the air in the upper chamber 39, the air and liquid in the pressure chamber 40 and the liquid in the working chamber 42 are under sufficient pressure to maintain the weight to be supported. Under compression, the annular member 21 is raised allowing free flow of liquid from working chamber 42 into pressure chamber 40. Control piston 32 rises until it abuts collar 30 but the rise of pressure in upper chamber 39 is small. As soon as the pressure in chambers 40 and 42 is equalised, annular member 21 is forced down by spring 37 until it engages lugs 23. On the recoil, the downward movement of disc 26 is retained by the pressure on the underside of control piston 32 so that the disc 26 does not open until the pressure in chamber 42 is substantially less than that in chamber 40 whereby recoil is checked. A similar action takes place during the recoil after extension.

Title: Improvements in or relating to methods of forming insulating films

Filed: 1945-04-10
Abstract: 590,039. Coating by electrophoresis. CINEMA-TELEVISION, Ltd., and HEAD, R. B. April 10, 1945, No. 8888. [Class 41] An insulating film is formed on a conductive support, e.g. a wire gauze or plate for use as the signal electrode in a television storage camera, by electrophoretic deposition from a suspension in an organic liquid, such as alcohol or acetone, of the inorganic combustion product of an organo-compound of silicon. In an example ethyl silicate alone or with a small amount of alcohol is burnt in a heated vessel through which air is drawn and the air carrying a smoke of silica grains is bubbled through the organic liquid until a suspension of up to 1 per cent by weight of silica has been formed. The article is connected as anode in the suspension to a voltage of 300. The electrophoretic action is preferably stopped before the whole of the insulating material is deposited. Alternatively, the silica may be precipitated from the smoke on a flat sheet and then scraped off and mixed with the organic liquid to form the suspension. Other alkyl silicates may be employed.
