Title: Fluid Operated Counting Device
IPC: G06M1/12
Filed: 1967-06-16
Abstract: 1,173,945. Counters. VEEDER INDUSTRIES Inc. 16 June, 1967 [17 June, 1966], No. 27932/67. Heading G4D. A counter wheel 60 is stepped by a fluidoperated motor 10. Application of an air pulse at 190 drives a control valve 132 to the right so that pressure air passes through conduits 150, 151 to bore 104, so driving piston 102 to the right whereby pawl 108 engages the next tooth 110 of the wheel 60. The end of the air pulse allows control valve 132 to return under spring pressure so that bore 104 exhausts through conduit 156. Piston 102 then returns under spring pressure to step the wheel 60. Movement of the control valve 132 to the right is normally limited by the periphery of cam 176, but at transfer notch 180 permits valve 132 to move further, so connecting pressure supply 150 to outlet 192 which feeds port 190 of the next higher denomination. A predetermined count may be set up by manually rotating serrated wheels 70 so as to over-ride a spring coupling 84. The wheels 70 step with the numeral wheels 60, attainment of zero aligning ports 200 whereby pressure air is supplied to a control. The counter may be restored to zero by supplying pressure to reset bore 222. Valve 214 moves to the right to cut off transfer port 138 and connect 222 to 192 and so to the next denomination. Air pulses then advance all wheels to 9, after which advance of valves 132 to the right connects all bores 104 to exhaust to complete zeroization. The counter is made up of separate modules for the several denominations.

Title: Improvements in and connected with valves
IPC: F16K1/14
Filed: 1933-04-08
Abstract: 406,404. Manually-controlled valves CLEMENT, R. F., 61, Norway Street, Portslade, Sussex. April 8, 1933, No. 28044/32. [Class 135.] A manually controlled valve with metal to metal closure contact comprises a loose metal ball valve member 7 which is pressed upwards away from its seating 8 by a spring 9 into contact with one side of an imperforate flexible diaphragm 2 which closes and seals the valve chamber 1<a>. The other side of the diaphragm presses against the head of a push pin 10 which is forced against the diaphragm by a spring 16 which is appreciably stronger than the spring 9. The valve 7 is opened by the spring 9 when the operating head 11 is turned to cause the riding of cam-shaped or wedge surfaces 17, 18 over each other to retract the pin 10 and release the pressure of the spring 16 on the diaphragm.

Title: Gas burners
IPC: F23N5/02
Filed: 1973-06-13
Abstract: 1430408 Burner controllers GOSUDARSTVEN N I I PROEKT INST "GIPRONIIGAZ" 13 June 1973 28044/73 Heading F4T Apparatus for controlling operation of spaceheating burners has an electromagnetic fuel gas valve 3, a device 20 to continually generate high voltage pulses at ignition spark gaps 9, a programming relay 10 having normally open contacts 11 in series with normally closed contacts 12 to jointly control valve 3 and device 20, an ambient temperature sensor 2, a step-down transformer 14 having its primary 29 in parallel with valve 3, an electromagnetic relay 15 having normally open contacts 17 in parallel with contacts 12, and a plurality of heat sensors 4 responsive to heat from respective burners and conjointly controlling energization of relay 15 from the secondary 22 of transformer 14. On first connecting the apparatus to an A.C. supply by closing switch 26, a red light 27 is energized via normally closed contacts 18 of relay 15. Upon energization of relay 10, contacts 11 close immediately and after a delay contacts 12 open and contacts 13 close. Thus when sensor 2 senses that heat is required, contacts 11 of relay 10 close to energize device 20, which operates contacts 21 to intermittently energize ignition transformer 5 throughout normal burner operation, and to energize transformer 14 which through normally closed flashback sensors 23 operates an electromagnetic relay 24 to open valve 3 via contact 25. If ignition is achieved within the delay of relay 10, sensors 4 close to operate relay 15 whereby red light 27 goes out and green light 28 comes on, the valve 3 and device 20 are maintained energized via contacts 17 and the circuit to bell 30 is disabled by opening of normally closed contacts 19. If ignition is not obtained within said time delay, contacts 12 open to de-energize valve 3 and ignition transformer 5 and contacts 13 energize bell 30. Sensors 4 have some time delay before opening following a flame-out of the corresponding burner, so that any short-term flame-out does not resultinshutdown, the relevant burner or burners being reignited by ignition transformer 5. A prolonged flame-out results in de-energization of relay 15 causing valve 3 to close, bell 30 to ring, green light 28 to go out and red light 27 to come on. The normally closed flashback sensors 23 have a time response faster than sensors 4 and a flashback results in de-energization of relay 24 and thus opening of contacts 25 and closing of valve 3 so that the opened sensor 23 closes again and valve 3 opens again. Momentary flashbacks thus result in closure of valve 3 followed by reignition whereas persistent flashbacks or other prolonged malfunctions result in sensors 4 opening leading to shut down as above. In an alternative form, Fig. 1, (not shown) sensors 23, relay 24 and contacts 25 are omitted and sensors 4 are arranged to respond also to flashback, short-term flame-out or flashback resulting in re-ignition and long-term flame-out or flashback resulting in shut down as above.

Title: Motor vehicle braking systems
IPC: B60T11/16
Filed: 1966-06-24
Abstract: 1,144,350. Hydraulic braking system. FORD MOTOR CO. Ltd. 24 June, 1966 [2 July. 1965] No. 28274/66. Heading F2F. An hydraulic braking system for a motor vehicle comprises a pedal operated master cylinder and piston 50 assembly and a vacuum servo-operated cylinder and spring-loaded piston 56 assembly. Movement of the pedal over an initial part of its travel causes the vacuum servo to operate and progressively pressurize the system up to a first predetermined line pressure and movement of the pedal over the remainder of its travel causes movement of the master piston to further progressively increase the line pressure of the system solely by the work done by the driver in exerting pressure on the pedal. The outputs of the master cylinder and servooperated cylinder are in parallel and pass through a common outlet 26 to the vehicle brakes. Vacuum is supplied to the servomotor piston 92 from a vacuum source and passes from one chamber of 86 of the motor to the other chamber 88 through a valve 52 which cooperates with the master cylinder piston 50. Actuation of the master cylinder piston 50 causes the valve 52 to engage a seat 122 cutting off the vacuum supply to the chamber 88 and on subsequent movement of the master cylinder piston allowing air to pass through a filter 118 and the valve 52 to the chamber 88 to operate the servo-piston 92. After the servo-operation, a further pressure increase in the braking system is provided by urging the master cylinder piston 50 further into the master cylinder, this further movement causing a valve member 136 to move to cut off communication between the servooperated cylinder and the master cylinder. The system is provided with hydraulic fluid from a reservoir 72 through apertures 102, 104 in the servo-operated cylinder. In a modification (Fig. 7, not shown) the master cylinder and the servo-operated cylinder are made as separate units such that they may be mounted in spaced relationship on the vehicle chassis.

Title: Improvements in or relating to diversity signal receivers
Inventor: EASTER BRIAN
IPC: H04B7/08
Filed: 1947-10-24
Abstract: 644,076. Radio receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 24, 1947,. No. 28513. [Class 40 (v)] In a diversity receiver having three or more signal channels, potentials proportional to the signal strength are derived from the signals in each channel and combined differentially with a potential derived from the signals and proportional to the strongest signal, the resultant signals being used to control a trigger circuit having the same number of stable states as there are channels, and which controls transmission means in each channel so that only the strongest signal channel is used for reception. Radio, intermediate frequency or low frequency signals from each of the channels A, B and C are passed to detector units AD, BD and CD respectively, so that potentials proportional to the peak signal strengths are produced across the rectifier loads AD4, BD4, CD4. Rectifiers AD6, BD6 and CD6 are associated with a common load ABC2, ABC3, across which is developed a potential proportional to the strongest signal. These potentials are combined in opposition, the resulting potential, which is positive, or in the case of the strongest signal, zero, being fed respectively to the control grids of cathode follower valves V4, V5 and V6. The outputs from the cathodes of valves V4, V5 and V6 are applied to the control grids of valves V1, V2 and V3. The grids of each of the valves V1, V2 and V3 is connected to the anodes of the other two valves, so that this arrangement forms a trigger circuit having three states of equilibrium in which two valves are conducting and one is cut-off. The anodes of valves V1, V2, and V3 are connected respectively to gating circuits A3, B3, C3, the arrangement being such that signals are passed to the common output circuit from one channel only, at any one time. The differential potentials, by controlling the operation of the trigger circuit, ensure that the output is taken from the strongest signal channel.

Title: Gas pressure machine
IPC: F04C23/00
Filed: 1964-07-10
Abstract: 1,064,872. Rotary compressors; raising and discharging liquids. UNION TANK CAR CO. July 10, 1964 [Aug. 7, 1963], No.28554/64. Headings F1F and F1R. A reversible rotary sliding vane machine for supplying air to or withdrawing air from a tank (12), Fig. 1 (not shown) through which sewage passes, comprises a rotor (37), Fig. 2 (not shown) concentrically mounted in an elliptical cavity (36) of a housing (31) with a clearance between the rotor and cavity on the minor axis of the ellipse of from about 0À0125 to about 0À0425 inches. This it is stated eliminates breakages of vanes, which are preferably made from self lubricating carboniferous material such as resin treated electro graphite, without any loss of efficiency of the machine. The machine has an even number of vanes (41) arranged so that there is always one vane between one of a pair of diametrically opposed parts (50), (51) and one between a pair of diametrically opposed parts (60), (61) with the parts (50), (51) being staggered axially of the rotor with respect to the parts (60, (61). On starting up the system with the tank (12) empty the machine is run in a direction to withdraw air from the tank. When sewage in the tank reaches a predetermined level a hollow electrode (24) mounted in a nozzle (80) of corrosion resistant electrical insulating material effects reversal of an electric motor 17 drawing the machine whence air from atmosphere is transferred to the tank to build up pressure therein to expel the sewage through a pipe 13 having a non-return valve 15. Should the sewage level fall the motor is automatically reversed to rotate in its previous direction and air, which may contain solid particles of sewage and liquid and cause vane breakage is withdrawn from the tank.
