Title: Improvements in or relating to power-operated booster apparatus for brakes, clutches and the like
IPC: B60T13/58
Filed: 1944-10-19
Abstract: 628,945. Fluid-pressure servo motor-control system; reducing-valves. PESCO PRODUCTS CO. Oct. 19, 1944, No. 20250. Convention date, Oct. 20, 1943. [Class 135] [Also in Groups XXVI and XXXIV] The force with which a hydraulic brake or clutch is applied is intensified by a booster operated by vacuum from the engine intake manifold, and a valve 79, Fig. 7, maintains constant the vacuum available to the booster irrespective of variations in the vacuum reservoir The pipe 77 connects the reservoir and the pipe 111 to the booster. A rod 86 is slidable in an air-vent hole 82 in a diaphragm cover 81, and in an adjusting-screw 104 which regulates the spring 107 and consequently the maximum vacuum supplied to the booster. The spring 107 and air-pressure on a diaphragm 100 tend to open the valve 92, 93, whilst air-pressure on one side of the diaphragm 84 and the vacuum on the other side tend to close the valve, so that as the vacuum in the pipe 111, and consequently on the peripheral parts of the diaphragm, increases the tendency for the valve 92 to close is increased. The booster 33 comprises a casing 152, 153 containing a diaphragm 147 secured to a plate 146 to which a lever 160 shaped to encircle a powerplunger 195 is pivoted at 165. The lever is pressed by springs 173 into contact with the piston 124 in the cylinder 126, and is pivoted to the stem 172 of the vacuum and air valve assembly. This comprises a vacuum valve 175 on the stem, a valve seat 178 on a sleeve 179 screwed to a sleeve 184 carrying the air valve 186, the seat 187 being on the plate 146. The sleeves 179, 184 are carried by a diaphragm 180 secured to the plate 146, and a spring 188 tends to keep the air-valve shut. When the brakes are " off ", the vacuum and air-valves of the unit 33 are closed and vacuum is on both sides of the diaphragm, but the hydraulic output of the unit 33 may be supplied as an input to another similar booster in which the hydraulic pressure is further intensified, and in the second booster stronger springs 173 are used, so that the vacuum valve is initially open and the airvalve closed. The head of the piston 124 houses a spring-loaded valve 119 which is kept open, in the fully-retracted position of the piston, by contact with the end plug 114. The initially generated pressure in the pedaloperated master cylinder passes through the open valve 119, ports 131, space 126, ports 132, space 218 around the power-actuated piston 195, and through the port 34 to the brakes, or to the second booster. When the pedalapplied pressure reaches about 20 lbs. per square inch, the piston 124 moves forward and the valve 119 closes, the air-valve 186 opens and the diaphragm 147 pulls the piston 195 forward. The diaphragm movement again closes the airvalve until the piston 124 is further advanced' by the pedal. The approach of the piston 124 to the plate 146 is limited by a collar 159 on a guiding pin 144, and strain on the lever assembly is thereby prevented. Specification 592,419, [Group XXXIV], is referred to.

Filed: 1922-07-26
Abstract: 183,836. Erban, R., and MadlÚ, A. July 26, 1921, [Convention date,]. Drawings to Specification. Suppltying current to moving and rotating conductoTs.- Devices employing liquid conductors, for example. mercury or amalgams comprise a pump and traps and discharge passages of comparatnvely large cross-section for liquid thrown or flowing out from the contact space which is maintained filled by the action of the pump. The traps may consist of grooves bounding the contact space and scrapers may be provided to prevent the formation of a rotating liquid ring in the groove by deflecting the liquid into the discharge passages. The trap grooves may be completely amalgamated the surfaces opposed thereto being unamalgamated or faced with insulating material. Tangential. instead of radial discharge passages may be used and the trap grooves may be of graduated depth around the circumference of the contact ring. A single groove may be replaced by a number of parallel grooves giving the same total section. To prevent the pump drawing in air the discharge passages may lead to a reservoir from which the pump delivers to an elevated reservoir with an overflow pipe thus equalizing the head of fluid supplied to the contact space. A needle valve may be used to control the supply to the contact space and the latter may be kept reliably filled by enlarging the bore of the supply tube beneath the needle valve to permit sufficient liquid to accumulate to compensate for variation in .the relative speeds of the contact surfaces. One or both contact surfaces may be provided with ribs or grooves designed to distribute the liquid uniformly over the contact space.

Abstract: 950,210. Controlling burners. ELCONTROL Ltd. Aug. 22, 1962 [June 7, 1961; June 13, 1961; July 4, 1961], Nos. 20637/61, 21232/61 and 24058/61. Heading F4T. [Also in Divisions G4 and H4] An ultrasonic flame detector comprises a transmitter consisting of an ultrasonic generator 1, transducer 2 and emitter tube 3 and a tuned receiver 9 the output of which is filtered and amplified to operate an alarm or recorder. The output from tube 3 is reflected by the flame and transmitted to the receiver, should the flame disappear, there will be no receiver input and relay 12 will be de-energized to operate an alarm and/or shut off the fuel valve. Only one tube 3 or 5 need be used in a system, the same tube also detecting any reflected signal. The flickering of the flame will modulate the carrier and the receiver may include a demodulator to avoid a false alarm due to spurious signals. In another embodiment (Fig. 2) the ultrasonic signals are transmitted through the flame, the mean flame envelope F normally masking the receiver tube. A " fail-safe " system can be provided by using tuned transducers 2, 9 (e.g. magneto-strictive piezo-electric) and feeding back from amplifier 11 to transducer 2 so that the circuit resonates only in the absence of flame; the rise of current being very sharp at this point and actuating the relay 12. The common axis 7, 8 of the receiver and transmitter tubes are offset from the flame axis so that a dangerously low flame is also detected. The system can be applied to a multi-burner installation (Fig. 3, not shown).
