Title: Improvements in or relating to a method for the production of rubber thread consisting of three or more united filaments
IPC: B29D99/00
Filed: 1937-07-16
Abstract: Rubber thread consisting of three or more filaments integrally united in a compact group, is made by extruding latex through a series of nozzles into coagulant at a common speed, and drawing the filaments over two suitably spaced rollers, the filaments being momentarily pressed and twisted by hand or other means during their passage between the rollers.  The twisting produces helices of opposite direction between the hand and the two rollers respectively.  That adjacent the second roller passes over, leaving the filaments twisted in one direction only between the rollers.  This twist passes over the second roller as the work proceeds, until about one and a half turns is left between the rollers, when a condition of equilibrium is reached, and the thread leaves the roller without twist.  The twist originally imparted should not exceed 5 or 6 turns.  The second roller is preferably driven at a surface speed greater than that of the first.  The degree of adhesion of the filaments may be regulated by the amount of drying prior to twisting them together. Specifications 219,635 and 290,313 are referred to.

Title: Improvements in or relating to fluid flow-control valves
IPC: F16K11/044
Filed: 1958-06-20
Abstract: 833,172. Vehicle power steering. ROSS GEAR & TOOL CO. Inc. June 20, 1958 [Sept. 23, 1957], No. 19924/58. Class 79(5) [Also in Group XXIX] A fluid-pressure servomotor system for use, for example, in vehicle power-steering, includes a double-acting piston and cylinder 10, 11, the piston rod 12 of which carries a control valve 13 comprising a valve spool 14 with lands 30, 31 between which is located an axially-displaceable ring member 24. In the neutral position shown pressure liquid from a pump 17 enters via a pipeline 18 and ports 33, 34 in the valve casing 13 and the ring 24, respectively, and passes via chambers 25, 26 and pipelines 15, 16 to opposite ends of the power cylinder 10, and also via a passage 37 in the spool 14 and a line 20 to a sump 19. Upon moving the spool 14 to the right, for example, the variation in the respective flow passage areas results in an increased pressure in chamber 26 moving the ring 24 to the left, so that when land 31 abuts against a shoulder 23 in the casing 13 the ring 24 is held against land 30, thus cutting off communication between lines 15, 18, the pressure liquid from line 18 passing via chamber 26 and line 16 to the power cylinder to move piston 11 to the right. Such movement displaces the valve casing 13 in the same direction, thus returning the valve to its neutral position. The pressure acting on the end surface of ring 24 produces feel. In a modification, Fig. 5 (not shown), the spool 14 is provided with three lands and two axially movable rings, while in further constructions, Figs. 8 and 9 (not shown), the valve lands are not formed integrally with the spool, and are arranged to permit limited rocking movement of the latter in operation.

Patent GB-1578554-A (GB)
Title: Methods of and arrangements for inserting digital signals into a digital-multiplex-signal
IPC: H04J3/08
Filed: 1977-05-16
Abstract: In transmission of digital time division multiplex signals, there is a requirement to mask out individual signals from the transmitted TDM signal (D1) in individual intermediate stations, and replace them by new signals which are at least almost synchronous, or else to assign free time slots of the TDM signal (D1). This new addition should be possible even if the transmitted TDM signals are badly distorted or not received at all. For this purpose, a second frame clock signal, which controls the addition of the digital signals arriving at the terminals (F22an), is generated in the transmission part (ST1) from the bit cycle signal (T1) (which is generated by the receiving part (ET1)) of the received TDM signal (D1). This second frame clock signal is controlled by the synchronisation pulses derived from the frame clock signal (TC) of the received TDM signal (D1) only in interference-free operation. <IMAGE>
