Abstract: 1,171,962. Film fibrillation. IMPERIAL CHEMICAL INDUSTRIES Ltd. 13 May, 1968 [9 June, 1967], No. 26790/67. Heading B5B. [Also in Division D1] Twisted fibrous articles such as yarns, strands, cords, twines and ropes are made from fibrillated polyethylene - 1: 2 - diphenoxyethane - 4: 4<SP>1</SP>-  dicarboxylate. Fibrillation is effected by drawing an extruded film or tape of the latter substance at least three times its original length in the longitudinal direction, heating the film or tape while under tension to a temperature of from 85‹ to 240‹ C. and twisting it about its longitudinal axis, the time of heating being such that the article is fibrillated. Heat treatment may be applied either before or after the twisting, or the heating and twisting operations may be carried out simultaneously. In the twisting operation the film to be twisted is restrained at a fixed point from the wind-up bobbin and is led on to the bobbin by a "traveller or "flyer" device. The fixed point may comprise nip rollers or a set of anchor rollers or it may be a compression die, e.g. of circular cross-section, through which the film is drawn.

Title: An improved method of and apparatus for the selective remote control of operations
IPC: G04C11/00
Filed: 1937-10-12
Abstract: 496,422. Electric signalling systems. LANDIS & GYR AKT.-GES. Oct. 12, 1937, No. 27649. Convention date, Dec. 24, 1936. [Class 40 (i)] Selective control is effected in accordance with the duration of the period between two interruptions in an alternating current, the first of which occurs when synchronous selectors at the transmitter and receiver are in their initial positions. The Specification describes a transmitter for use with the receiver described in Specification 494,792. The transmitter shown is provided with three push buttons D1-D3 for effecting operations at receivers E1-E3 respectively. When a button, say D3, is pressed, relay Z3 pulls up, locks and operates relay V over transmitting selector K<1> in the normal position. Motor S2 thereupon drives a timing switch K<2> which has alternate contacts connected together in two groups, and relay Y operates over group e<1> to open the control circuit to conductor B1 of the receivers whereby the receivers are started up on re-closure of the circuit by the release of Y when switch K<2> leaves an e<1> contact. When K<2> reaches an e<2> contact, X pulls up to disconnect all the push buttons, and S<1> is energized to drive the selector K<1>, the circuit of S<1> being maintained over off normal contacts f<1>. Relay V falls back and timing device S2, K<2> stops, but when selector K<1> reaches position 3, V pulls up again so that the circuit to the receivers is again interrupted by Y under the control of the timing device. The selector K<1> moves on until shortly before reaching normal relay W operates over contacts f<2> and releases Z3, and in the normal position, contacts f<1> open to stop motor S<1>.

Title: Measuring and distributing device for fluids, especially lubricants
IPC: F16N27/00
Filed: 1945-10-23
Abstract: 601,279. Force feed lubricating. FIORETTI, D. Oct. 23, 1945, No. 27884. Convention date, May 28, 1943. [Class 12 (iii)] Fluid such as lubricant is fed to points of use in regulated quantity from a pressure line, the pressure in which is intermittently relaxed, by a device comprising two communicating cylinders of different size arranged one above the other with pistons slidable therein, the lower piston 4 which can act as a valve to allow passage of lubricant in one direction only having also a closure pad 6 to close a transfer passage 8 between the upper and lower faces of the upper piston 9 ; the upper piston 9 is urged downwardly by a spring 7. The quantity discharged is regulated by the piston stroke through the descent of the pistons being limited by an adjustable stop plug 5. Accordingly with the main supply pipe pressure admitted to the space below the lower and smaller piston 4, the pistons will rise, the transfer passage 8 in the upper piston 9 being closed by the pad 6, and lubricant will flow past the cup leather of the lower piston 4 to the inter-piston space 10 which is expanding by reason of the difference in the piston areas. Meanwhile, lubricant previously at the upper face of the upper piston 9 is forced to the point of use. When the pressure in the main supply pipe is relaxed the pistons descend under the action of the spring 7 so that the inter-piston space 10 contracts with the' lubricant therein passing by the passage 8 to the upper side of the upper piston, it being noted that the lower and smaller piston must, by reason of the incompressibility of the lubricant, separate sufficiently to open the passage 8. The above cycle is repeated at each application and relaxation of pressure in the main supply line. An arrangement in which the lower piston is of larger area so that the inter-piston space contracts on the pressure stroke to discharge to the upper face of the upper piston and so to the point of use is also described Figs. 5-7 (not shown), the interpiston space being re-charged when it is expanded on the spring-return stroke.

Title: Improvements in or relating to phase comparison apparatus
Inventor: ROBERTS GRAHAM ESTYN
IPC: H03M1/00
Filed: 1962-07-19
Abstract: 1,016,982. Selective signalling systems. DECCA Ltd. Oct. 18, 1963 [July 19, 1962; Aug. 31, 1962], Nos. 27902/62 and 33598/62. Heading G4H. In a system for measuring the phase difference between A.C. signals on leads 10, 11, Fig. 1, the output from one stage of a counter 21 which is continuously driven by an oscillator 22 is mixed with the signal on lead 11, and the resulting sum or difference frequency is in turn mixed with the reference signal on lead 10. The output of mixer 25 is of the same frequency as the output from counter 21 but has a phase corresponding to the phase of the signal on lead 11. Pulse shaper 26 produces a square pulse to open gates 27 at a time in each cycle of counter 21 which represents the phase difference to be measured, and a digital representation of this phase difference is transferred from counter 21 to a register 28. Filter 23 converts the square-wave output of counter 21 to a sinusoidal signal. The signal on lead 11 may represent the angular position of the rotor of a synchro 16. The mixer 24 may be a singlesideband modulator or a phase shifter driven by a synchronous motor. A number of such phase measurements may be made simultaneously by a circuit which includes a common mixer supplied with reference A.C. and the output of counter 21, this mixer providing the second input to individual mixers receiving the respective variable phase signals. The outputs of the individual mixers are used to gate the contents of the counter 21 to respective stores. A similar circuit, Fig. 4, may be used to produce a signal the phase of which corresponds to a digital input from a register 67. Counter 60 is driven continuously by oscillator 61 and comparator 66 produces an output, the phase of which depends on the input from register 67. The output of mixer 65 is of the same frequency as the reference signal on lead 64 but carries the phase information and may be used to drive a synchro.
