Title: Improvements relating to hydraulic transmissions
IPC: F16H61/46
Filed: 1969-05-16
Abstract: 1,206,256. Hydrostatic transmission. INTERNATIONAL HARVESTER CO. 16 May, 1969 [23 May, 1968 (2)], No. 25088/69. Heading F2D. In a vehicle hydrostatic transmission having by-pass valve means preventing excessive pressures during over-running to prevent overspeeding of the pump and engine, an anti-coast valve 146 prevents complete by-pass of fluid during such pressure relief to maintain engine braking effective. The transmission comprises a pump 15A and a motor 15B of the variablestroke swash-plate type having by-pass valves 19, 19a between their pressure and return lines. The valves have spring-loaded spools 38, 38a subject to the pressure in a line 18a, 18 acting via a line 20, 20a respectively and connected to a respective transmission line. Passages having restricted orifices 48, 47 and 48a, 47a are provided in the valves and lead via lines 46, 46a to chambers between relief valves 82, 84 and 82a, 84a which are connected by the anticoast valve 146 and a line 50 to a manuallycontrolled spring-loaded relief valve 52. Valves 84, 84a are selectably unseated, according to the direction in which motor 15B is to be driven, by a slidable cam 136 acting through push-rods 130, 130a and positioned by a forwardneutral-reverse lever 140. The relief valve 84, 84a which is unseated is that which has its associated chamber open to the transmission line which is the low pressure line while the pump is driving the motor. If the motor overruns the pump, the pressure in the normally low pressure line rises and lifts the spool 148 of valve 146 to block line 50. The rising pressure is also exerted, by way of the unseated valve 84 or 84a and a passage 162, on the underside of the seated valve 84a or 84 to open that valve, thus reducing the pressure acting on the rear of spool 38a or 38 which is thereby shifted against its spring loading by the pressure on its front face to interconnect the lines 18, 18a. The spool 148 of valve 146 is normally held down by high pressure acting on its top via whichever valve 82 or 82A is connected to the high pressure transmission line. The high pressure is thus normally delivered via line 50 to the valve 52 where excess pressure may automatically be vented to a line 53 or, by depressing pedal 76, the spring loading of valve 52 is reduced to open the by-pass valve under high pressure to neutralize the transmission during emergency stops. The pedal may also be used to provide smooth drive take-ups.

Title: Improvements in or relating to radio navigation
Inventor: EARP CHARLES WILLIAM
IPC: G01S3/54
Filed: 1951-10-29
Abstract: 694,549. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. Oct. 29, 1951, No. 25225/51. Class 40 (vii). Relates to direction-finders or phase beacon systems of the type in which the received signal is amplitude modulated due to the rotation of a directive reception or radiation pattern, the phase of the modulation being compared with that of a reference signal synchronized with the rotation to indicate the bearing of the transmitter from the receiver or vice-versa. In such systems a multi-lobe pattern may be employed to give an accurate but ambiguous indication and according to the present invention the ambiguity is avoided by utilizing a single lobe pattern, e.g. a cardioid, Fig. 4, and a multi-lobe, e.g. eight-lobe, pattern, Fig. 5, which are rotated synchronously at 50 c/s. to give at the receiver a 50 c/s. signal whose phase depends only on a particular one of the multi-lobes. As described, the 50 c/s. and 400 c/s. bearing-dependent signals 57 and 58, Fig. 6, are converted to pulse trains 59, 60 which are applied to a gate circuit to give a 50 c/s. pulse train 61 which is converted to a 50 c/s. sine wave 62 by a filter and applied to a phasemeter together with the 50 c/s. reference wave 56; alternatively the reference signal may comprise a 50 c/s. pulse train which is compared with pulse train 61. In order to compensate for any misalignment of the radiation patterns, the bearing dependent signal 57 is applied to its pulsing circuit through a phase shifter. - Phase beacon system, Figs. 1 and 2 (not shown). In this system the carrier frequencies of the two directive patterns are F+3 and F+4 kc/s. respectively and the 50 c/s. reference signal is frequency modulated on to a 5 kc/s. sub-carrier which is amplitude modulated on to a carrier F kc/s. which is transmitted from a non-directional aerial. The cardioid pattern is produced by applying the F+3 carrier to three linearly spaced aerials with relative phases of 0, 90 and 180 degrees and the eight lobe pattern is produced by applying the F+4 carrier to a circular array of eight aerials, alternate aerials being fed co-phasally and the intervening aerials being fed in reversed phase. The patterns are rotated by rotating the arrays or by feeding stationary aways through rotating goniometers. Direction-finder, Fig. 3 (not shown). In this case the signals received by the two directive aways are applied to separate detectors and the reference signal is generated at the receiver.

Filed: 1939-09-11
Abstract: 534,642. Treating textiles with liquids. BRITISH CELANESE, Ltd. Sept. 11, 1939, No. 25555. Convention date, Sept. 10, 1938. [Class 15 (ii)] [Also in Group IX] Filaments, yarns, or threads of an organic derivative of cellulose containing a resin are highly twisted to form crape threads and during insertion of the crape twist the filaments or threads are subjected to the action of a hot aqueous liquid or vapour. The resin may be applied to the filaments in the form of an aqueous emulsion or it may be dissolved in the spinning solution used for forming the filaments. The cellulose derivative may be cellulose acetate or other cellulose ester or ether. The resin, which is preferably water-insoluble, may be a polymerized ester of a substituted acrylic acid, e.g. methyl methacrylate. The resin may be applied to the filaments or yarns while they are travelling by passing them in contact with rollers, rods, or pads moistened with the resin solution or dispersion, e.g. a dispersion in water containing a sulphated fatty alcohol. Twisting may be effected in the presence of steam or hot water. The yarn may be drawn off over the head of a rotating package through a guide fixed in line with the axis of rotation and then passed through a hot aqueous fluid on its way from the guide to a bobbin. A single steam chamber may be provided for several twisting devices. The yarns may be wet with water before passing through the steam chamber. The steam, may be at a raised pressure. When twisting is carried out in presence of hot water this may be used at a raised pressure. Twisting may be effected in one or more stages. A sixth to one-quarter of the total crape twist may be effected without the hot aqueous fluid treatment, and then the crape twist is completed while treating with hot aqueous fluid. The twisting may be such that the threads are smooth and cylindrical in appearance and the threads may have an apparent density of more than 85 per cent. of the actual density of the filaments. The crape threads may be used for the weft or warp of fabrics. Threads of low twist may be used for the warp and both right- and left-hand twist crape threads may be used for the weft The cellulose derivative crape threads may be associated in the fabric with low or high twist threads of other materials, e.g. natural silk or regenerated cellulose. Crape effects are produced in fabrics containing the high twist threads bv treatment with hot aqueous liquids. The delustring effect of these liquids may be minimized by incorporating salts or sugars. Specifications 348,589 ; 437,019, 438,590, 438,591, [all in Group IX], are referred to.
