Title: Variable speed constant power fluid transmission
IPC: F16D31/06
Filed: 1959-12-07
Abstract: 890,545. Hydraulic transmission of power. WAGNER, E. E. Dec. 7, 1959, No. 41505/59. Class 69 (2). [Also in Group XXII] A variable-speed constant-power fluid transmission comprises a balanced vane-type unit having an independently-rotatable housing 20, Fig. 3, which encloses a rotor 15 to provide pumping chambers, is formed with inlet and outlet passages 22, 22a, 23, 23a, and connected to an output shaft 35, a stationary body 27 cooperating with the end to form a rotary valve having inlet and outlet ports, and a variabledelivery reversible unit 54, Fig. 10a, having a fixed housing which encloses a rotor 69 to form pumping chambers and is provided with inlet and outlet passages 63, 64 connected to the inlet and outlet ports of the balanced vane-type unit for transferring the speed-regulating fluid volume between the units, the rotors of the balanced vane-type unit and the variabledisplacement unit being coupled to an input shaft 55 mounting a driving means. The balanced vane-type unit has a fixed displacement and consists of an input-shaft 10, Fig. 3, which is splined to the rotor 15 having vanes 18, Fig. 7, extending into chambers 38, 38a formed in a cylinder 19 of the housing 20. Passageways 22, 22a and 23, 23a are provided in the housing and co-operate with an inlet port 28 and outlet port 29, respectively, in turn connected to inlets 30, 30a and outlets 31, 31a, Fig. 5, in a valve body 27 held against rotation by springs 75, 76 abutting a casing 34. A member 39 permits the fluid expelled from the valve to act against a surface 43 in the casing to balance the force of fluid passing through the outlet 31. The fixed-displacement vane-type unit is incorporated in the transmission shown in Figs. 10a and 10b and has its rotor 70 driven by an input shaft 55 which is connected to the rotor 69 of the variable-delivery reversible unit 54 and is driven by an electric motor 58 or other driving means. The output shaft 50 of the transmission may drive the spindle of a machine-tool. The unit 54 controls the flow of fluid passing through the fixed-displacement unit 51 and has ports 63, 64 connected to the ports 61, 62 of the unit 51. When the adjusting-ring 71 of the unit 54 is in its central position, flow through the units 51, 54 is stopped and the output shaft 50 rotates at substantially the same speed as the input shaft 55. Movement of the adjusting- ring 71 in one direction causes fluid from the unit 51 to be pumped through the unit 54 which in this case acts as a motor and drives the input shaft 55 so that the output shaft is driven at reduced speed but with increased torque. When the ring is moved in the opposite direction, the unit 54 acts as a pump and the output shaft is driven at increased speed but with less torque. The displacement of the unit 54 may be such as to reduce the direction of rotation of the output shaft. Temperature-limiting controls, relief valves, shuttle valves and flushing valves may be incorporated in the transmission.

Title: Automatic gearbox
IPC: F16H63/02
Filed: 1964-10-12
Abstract: 1,065,359. Change-speed control. HANS GLAS G.m.b.H., ISARIA-MASCHINENFABRIK. Oct. 12, 1964 [Oct. 15, 1963], No. 41553/64. Heading F2D. An automatic change-speed gear is arranged to prevent the engine dropping below idling speed in the event of the accelerator pedal being released during gear shift, in order to ensure clutch re-engagement. The system shown is identical with that of Fig. 1 of Specification 1,065,358-see Abridgment thereof- and comprises a throttle valve operating lever 25 connected by a spring 28 to follow the movements of a pedal-operated lever 27. A pump 1 is connected to a valve unit incorporating a pressureregulating valve 12, a solenoid-operated exhaust valve 8, and control valve 16 connected to the clutch-operating lever 18. Upon initiation of a gear shift the solenoid 6 is energized to close exhaust valve 8, the pressure in the system then rising to cause valve 16 to operate lever 18 for clutch disengagement. At the same time pressure liquid passes through an aperture 14a to a pipe-line 20 to project a pair of piston-rods 23a, 24a from a cylinder housing, whereby in the event of the pedal being released the lever 25 is rotated by spring 28 to engage the end of rod 24a and is thus held in a position for a low engine speed above idling. Upon completion of a gear change the solenoid 6 is de-energized to open exhaust valve 8, but a restriction 14b operates to prevent retraction of rod 24a until the pressures created by pistons 16, 24 are equal when the clutch is on the point of re-engagement. This ensures that the clutch is moved towards engagement before the throttle valve can be opened, and this feature forms the subject of Specification 1,065,360.

Title: Processes for producing polychlorinated ethanes and polychloro ethylenes
IPC: C07C21/04
Filed: 1968-08-30
Abstract: 1,237,752. Chloroethylenes and chloroethanes. CENTRAL GLASS CO. Ltd. 30 Aug., 1968 [30 Aug., 1967; 16 Dec., 1967; 2 Feb., 1968; 3 Feb., 1968], No. 41621/68. Heading C2C. Polychlorinated ethanes having at least three chlorine atoms in their molecules are produced by the liquid phase chlorination of a mixture of CH 2 Cl-CH 2 Cl and at least one mono- or dichloroethylene, chlorine being passed through the mixture in excess of the amount required to add to the chloroethylene. The chloroethylene may be contacted with a gas containing molecular oxygen before being introduced to the chlorination reaction system. The polychlorinated ethanes may be pyrolysed to di- and polychloroethylenes, optionally after the removal of dichloroethane. The pyrolysis may be carried out in the presence of a catalyst, e.g. BaCl 2  on active carbon, and accelerators such as O 2 , Cl 2 , Br 2 , CCl 4  or C 2 Cl 6  may also be added. Cis- and trans-1,2-dichloroethylenes may be separated from the pyrolysis product and recycled to the chlorination step. If desired, some or all of the 1,1-dichloroethylene in the pyrolysis product may also be recycled to the chlorination step. Alternatively, the pyrolysis product is reacted with hydrogen chloride, which may include that evolved during the pyrolysis, in the liquid phase to convert selectively the 1,1-dichloroethylene to 1,1,1-trichloroethane. This reaction may be conducted in the presence of a Friedel-Crafts catalyst, e.g. FeCl 3  or AlCl 3 . Trichloroethylene and tetrachloroethylene may be obtained as products by separation from the pyrolysis product prior to the hydrochlorination reaction or from the hydrochlorination reaction product. Cis- and trans-1,2-dichloroethylenes may be separated from the hydrochlorination reaction product and recycled to the chlorination reaction. Specified products of the chlorination reaction are CH 2 Cl-CHCl 2 , CHCl 2 ,-CHCl 2 , CH 2 Cl- CCl 3  and CHCl 2 -CCl 3 . Specified products of the pyrolysis reaction are CHCl=CHCl, CH 2  = CCl 2 , CHCl=CCl 2  and CCl 2 = CCl 2 .

Title: Improvements in or relating to movable stop devices for calculating machines
IPC: G06C7/10
Filed: 1960-12-06
Abstract: 943,645. Calculating machines, stop devices. PAILLARD S.A. Dec. 6, 1960 [Dec. 7, 1959], No. 41974/60. Heading G4B. A movable stop-device for a single-bank calculating machine is characterized in that the escapement device comprises an actuating part disposed opposite the control members (keys) and a denominational row of stops so as to be moved by that of the stops which is lowered in such a manner as to permit a complete escapement cycle of the carriage. The carriage, consisting of horizontal plates 2, 3 secured to lateral arms 4, 5, carries rows of twelve movable stops 10 and is slidable under the action of a spring 11 in the direction indicated by arrow F. On depression of one of the twelve control keys 26 a spring 32 attached to the bottom of the stem pushes an aligned stop 10 from its rest position to a lowered position, where it is retained by a spring 33 in a notch 34. The lower part of the stop, in turn, pushes a plate 17, Fig. 5, pivoting about a spindle 14, which presses down a peg 18 on a pawl 13 causing this to pivot at the same time as plate 17 and to withdraw its beak from a hole 15 in the plate 3 so that the carriage is released. On movement of the carriage from one row to the next the pressure on plate 17 is released and hence permits the pawl 13 to engage with the following hole 15. Further keys can thus be depressed before the preceding one has been released. The stops are reset during the return movement of the carriage by an inclined edge 37 of plate 17 automatically positioned by a stop 20.

Title: A Programming Valve Operable by Applied Pressure Pulses
Inventor: LOVELESS STANLEY MARTIN
IPC: F15B11/20
Filed: 1967-09-19
Abstract: 1,197,307. Multi-stable state valve. GENERAL GAS LIGHT CO. 19 Sept., 1967, No. 42661/67. Heading G4P. [Also in Divisions F2 and G3] A valve 10 connected between a pulsating fluid source S and a load L, e.g. a pressure fluid cylinder, or a fluid actuated valve, comprises a valve member 76 actuated at the end of the stroke of a piston 71 which is moved by a predetermined number of pulses of the source S determined by segments 107 co-operating successively with stops 63. The cycle of operation of the valve starts with the piston 71 abutting the leftward end of a chamber 12. A pulse of fluid at the inlet 23 acts to close the valve member 76 on to a seat 101 and move the piston to the right. Fluid also passes through a restricted orifice 112, into an annular chamber formed by a seal 113 to act on the segments 107 and move them beyond the periphery of the piston to abut a stop surface 63. When the pressure in the chamber 17 drops below that required to overcome an annular spring 118, marking the end of the first pressure pulse, the segments 107 are retracted, allowing them to clear a flange 64 on the next stop 63, and the piston is ready to be acted upon by the next pulse. The piston can be acted upon by any number of pulses, determined by the number of stops 63, until the valve member 76 abuts an end 43 of an outlet conduit 31, whereupon the valve is opened and fluid is allowed to flow to the load L. At the end of the last pressure pulse, the pressure in the inlet chamber 17 drops below that at the outlet end, so that the piston is moved backwards until the valve member 76 abuts a rod 21, and is moved to its open position. The cycle of the valve can then be repeated upon an occurrence of another series of pulses. The number of pulses needed to open the valve can also be adjusted by axially moving the conduit 31 and setting it in another position by means of a set screw 41 locating in a selected annular groove 39. The segments 107 may be replaced by diametrically opposed pistons (131) connected together by springs (136), Fig. 5 (not shown). An annular elastomeric ring (151), Fig. 6 (not shown), may function as a combined seal and stop member. Two valves 10 may be connected in series, Fig. 12 (not shown), so that a load is actuated after a number of pulses determined by the product of their stop surfaces. In Figs. 8 to 11 (not shown), the piston (71B) has a bore (201) and is axially movable on a stem (166) having a bore (168) therethrough. Fluid from the source S passes through the bore (168) to actuate a valve (76B), and past a regulating valve (173) into the leftward end of bore (17B). A relief valve (176) acts during the return stroke of the piston (71B). In this embodiment the stop segments are of outwardly opening V-shaped cross-section

Abstract: 1443881 Valves F R SAUTER AG 2 Oct 1974 [31 Oct 1973] 42781/74 Heading F2V [Also in Division G3] A valve assembly for use in a pneumatic or hydraulic amplifier, Fig. 2 (not shown), comprises a tiltable plate 10 contacted on one side by a pivot 13 and an actuator 24 and on the other side by an inlet valve element 11, an outlet valve element 15 and a compensator 9 resiliently and, optionally, pressure biased to apply a closing force to the valve elements 11, 15. Downward movement of the actuator 24 due to increase in signal pressure applied above an actuating membrane (32) of the amplifier causes the plate to tilt about an axis (26), Fig. 5 (not shown), passing through the pivot 13 and valve element 15, whereby the inlet valve element 11 is opened by incoming fluid which then increases the pressure of fluid in chamber 8 and in an output line 20 leading to a control member (34). The inlet valve element re-closes when the output pressure, communicated through a feed-back line (31) to the underside of the membrane, reaches a value sufficient to return the membrane to its neutral position. Upward movement of the actuator due to a decrease in the signal pressure permits a spring 21 to force the plate upwardly and tilt it about an axis (27) passing through the pivot 13 and the valve element 11, whereby the outlet valve element 15 is opened by adjustable spring 16 to reduce the pressure in output line 20, whereafter the outlet valve element re-closes. The housing parts 1, 2 may be formed as a single part (29), Figs. 6 and 7 (not shown).
