Title: Pneumatic control mechanism for steering road vehicles
IPC: B62D5/08
Filed: 1944-11-14
Abstract: 591,545. Fluid-pressure servomotor-control systems. BENDIX-WESTINGHOUSE AUTOMOTIVE BRAKE CO. Nov. 14. 1944, No. 22484. Convention date, Oct. 21, 1943. [Class 135] In pneumatic steering gear in which a manually operable member controls the admission of pressure fluid to an actuator for the steering gear, means is interposed between the source of pressure fluid and the actuator control means for varying the, actuating. pressure automatically in accordance with displacements of the steering gear from an intermediate position. A shaft 4 connected to the manually operable member carries a lever 6 to which is pivoted at 7 a lever 8 pivoted at 10 to a further lever 11, the upper ends of both levers 8, 11, being pivoted on shaft 4 but the upper end of lever 8 having a slight play thereon. Lever 11 is connected to the steering wheels through a drag line 5 and also by a link 28 to the servo.piston 20, the latter carrying a sleeve 21 which slides through a seal in the end face of a cylinder 19. Actuation of the shaft 4 rotates lever 6 which causes lever 8 to rotate about pivot 10, and the upper end of the latter lever to which a rod 61 is connected moves slightly to actuate the control valves 27. The subsequent movement of servo-piston 20 will rotate lever 11 to actuate the steering wheels and also to rotate lever 8 about its lower end 7 and so reset the control valves 27. The latter comprise two sets of self-lapping valves connected in the conduits 25, 26 leading to the two ends of the servo-cylinder. Actuation of rod 61 tilts a see-saw lever 57 and depresses one of the stems 49 to close exhaust valve 40 and then open inlet valve 38. Pressure fluid entering at 32 flows into chamber 34 and out to the servocylinder through port 47, at the same time pressure will build up in chamber 34 until it can push up a piston 36 to allow the inter-connected valves 38, 40 to rise under the action of loading spring 39 to shut off both valves. The pressure built up in chamber 34 will be transmitted to the operator as " feel." On reverse actuation of lever 57, piston 36 will be pushed up by its loading spring, and the outlet valve will open to allow pressure fluid to flow from the servocylinder through passages 41, 43 in the piston and out through exhaust port 45. A further valve 68 ensures that the pressure of the fluid. supplied to valves 27 is adjusted so that it increases progressively as the turn it is desired to make is increased, the valve being actuated by a cam 90 on the hub of lever 6 which engages an adjustable follower 89 to increase the spring loading of a diaphragm 80. The latter carries a tube 83 which actuates spring loaded selflapping, interconnected inlet and exhaust valves 76, 78. Pressure-fluid from a reservoir 65 enters a chamber 71 and flows past the inlet valve to a chamber 72 connected with the valve 27. The pressure in chamber 72 is communicated to a chamber 73 in contact with the diaphragm through a port 81.

Title: Injector using exhaust steam
IPC: F04F5/46
Filed: 1939-08-08
Abstract: 531,941. Injectors. TROFIMOV, I. Aug. 8, 1939, No. 22916. [Class 71] In an exhaust steam injector, which is started by means of live steam, the exhaust steam chamber is divided into two parts, one of which can be put out of action by means of a valve, when the pressure of the exhaust steam falls, live steam being then supplied, so that the injector works on a mixture of exhaust and live steam. The two parts C, I of the exhaust steam chamber are separated by a partition K, and steam is supplied to the part C from a main inlet D under the control of a valve 10, and to the part I by a branch-pipe E controlled by a valve 11. To start the injector, a valve 14 is slightly raised, to admit live steam to the nozzles from a chamber A. When water from a chamber F enters the injector, the valve 14 is raised farther, and live steam passes by a passage B into the exhaust steam chamber C. When the ejector has begun to pump water, exhaust steam is turned on by rotation of an eccentric 20, which opens the valve 10 and closes a valve 21, which cuts off the live steam from the chamber C. When the exhaust steam pressure is sufficient, the valve 11 is opened and the valve 14 is closed, so that the ejector works on exhaust steam alone.

Abstract: 1477502 Counters; zeroizirig mechanism H BUD 13 May 1975 [22 May 1974] 22946/74 Heading G4D In a counter of the kind in which transfer pinions 31 are withdrawn from engagement with number wheels 29 while fingers 61 act on heartshaped cams 27 to reset the number wheels to zero, the transfer pinions are shifted by a cam 81 which rotates about the shaft 19 of the number wheels during the initial movement of a resetting button 67 to shift the shaft 33 carrying the transfer pinions; further movement of the button 67 brings the fingers 61 to engage the resetting cams 27 and final movement of the fingers 61 causes an abutment 93 rigid with the fingers to restore the cam 81 to release shaft 33 and allow the transfer pinions to reengage the number wheels while the fingers still engage the resetting cams. Cam 81 is rotated by a flexible pawl 75 formed integrally with the resetting button 67 and which acts on a piece 77 attached to the cam 81; after the initial movement pawl 75 slips clear and thereafter offers no resistance to the push button. The fingers 61 pivot about a shaft 39 when a bar 63 is depressed by the push button 67 after the pawl 75 has slipped. The abutment 93 brings cam 81 back to the point at which shaft 33 is on the brink of the notch 83; a spring biasing the pinions towards the number wheels completes the movement. When the transfer pinions are withdrawn, square extensions 53 on each of them engage with blade springs 99 to correctly align them; as the resetting fingers are moved a surface 60 on them flexes the respective blades 99 so that they remain in engagement with the square sections until the pinions are engaged with the number wheels. Reference is made to Specification 1,477,501.

Abstract: 1317452 Extruding into moving mould means JTAGA 14 May 1970 [14 May 1969] 23427/70 Heading B5A In a process wherein molten thermoplastics; e.g. polyolefins or polyamides or foamed thermoplastics, are extruded through an orifice defined between a stationary die 1 and a moving chain of moulds 2 which define a ridged surface 2, 2<SP>1</SP>, leakage of thermoplastics rearwardly of the die is prevented by one or more die barrier members 5 which are movable to maintain contact or close proximity with the mould surface. In the Fig. 5 embodiment, the member 5 is biased into contact by a spring 6, and in the Fig. 6 embodiment (not printed) the member is pivotally mounted on the underside of the die and contact is maintained by the extrusion pressure. The contact may alternatively be effected by reciprocation of the member by a cam track, either running along the side of the moulds, or located independently of the moulds. The thermoplastics flow from the front underside of the die 1 may also be regulated by one or more freely rotatable or driven cooled pressure rollers, 12a, 12b, Fig. 9, the temperatures of which are independently adjusted by internally circulated cooled or warm water, or alternatively, or in addition, by an endless belt passing over the cooled rollers, Fig. 10. The cooled rollers or belt also act to avoid moulded article deforming stresses, by effecting cooling of the contacting thermoplastics surface under the same conditions as the opposite surface cooled by the moulds, and similarly act to effect the formation of a skin layer with expanded plastics when the rolls or belt provide a gradually widening space between the moulds in which foam expansion is effected. The roll 12a, Fig. 9, may be recessed as at j to pattern the extrusion, or may be a printing roll to effect anastatic, intaglio, or lithoprinting. A printed paper c, Fig. 10, may be laminated to the extrusion, or may alternatively be applied by an endless belt located subsequent to an initial cooling roller.

Abstract: 1,058,744. Frequency demodulator. DATACONTROL SYSTEMS Inc. June 5, 1964 [June 6, 1963], No. 23488/64. Heading H3A. The response of a phase locked loop comprising phase comparator 12, loop filter 14 and voltage controlled oscillator 13, acting as a frequency demodulator is linearized by the addition of a low-pass filter 15 and amplifier 16, whereby overshoot and ringing in the output signal when a step change in frequency of the input signal occurs is minimized. The transfer function of the phase locked loop is a complex fraction having a numerator with a single real root termed a zero and a denominator with one real root and two complex roots termed poles. The amplifier is designed to have a transfer function with a real pole and a real zero which substantially equal and cancel the real zero and real pole, respectively, of the loop and the transfer function of the low-pass filter is arranged to include an even number, at least four, complex poles distributed such that with the two poles of the loop a gaussian distribution for the six poles is obtained. By arranging the relative values of the six complex poles their effect on the overall phase transfer function may be made substantially linear.

Title: Improvements in or relating to the manufacture of lead chromate and substances containing lead chromate
IPC: C09C1/20
Filed: 1933-08-24
Abstract: Lead chromate is produced by adding chromic acid to an aqueous suspension of lead oxide, carbonate or basic carbonate containing a small amount of hydrofluoric, fluoboric, or fluosilicic acid, or a compound providing the same anions as any of these acids, for example, lead fluoborate.  The amount of the catalytic agent does not usually exceed 5 per cent and is preferably present in \ba1/2\be to 3 per cent of the amount which can theoretically react with the lead compound.  A preferred form of lead oxide is litharge.  The chromic acid should not be added at a rate greater than that at which it enters into reaction.  Periods of from a few minutes to three hours are specified.  The temperature at which reaction is effected varies from below atmospheric to above 100 DEG  C.  Basic lead chromate of dark orange colour is obtained by using less than the molecular equivalent of chromic acid.  A pigment of lighter colour consisting of lead chromate and sulphate is produced by replacing the chromic acid by a mixture of chromic and sulphuric acids.  The Specification as open to inspection under Sect. 91 comprises also the use, as catalysts, of acids such as acetic, nitric, hydrochloric, perchloric and formic acids, of alkalies such as caustic soda or potash, or ammonia, of lead salts such as lead acetate, or of other salts, such as sodium chloride, ammonium nitrate and aluminium acetate or nitrate, having a tendency to dissolve the lead compound.  This subject-matter does not appear in the Specification as accepted.
