Title: A power braking device
IPC: B60T13/44
Filed: 1965-08-24
Abstract: 1,065,462. Master cylinders. BENDIX CORPORATION. Aug. 24, 1965 [Sept. 15, 1964], No. 36321/65. Headings F2E and F2F. A combined master cylinder and hydraulic pressure control valve has separate outputs 158, 162, for connection to the front and rear wheel brakes, respectively, of a vehicle and is arranged to raise the pedal in the event of a failure of the supply pressure from a pump to make available a longer pedal stroke for manual operation. Normally fluid under pressure supplied by the pump and an accumulator enters at port 32 and enters chamber 120 by way of passage 122. Piston 110 moves, with piston 62, to bring rod 106 leftwards to lower an associated pedal, fluid from chamber 74 passing through passages 66, 88 and 54 to reservoir 46. When the operator depresses the pedal, rod 106 moves to cause plunger 88 to abut and then lift ball 82 from seat 84, pressure fluid then passing check valves 126, 134, through passage 68, seat 84, passage 66 to chamber 74 and discharging to the front brakes through port 158. The pressure on piston 58 causes the latter to pressurize fluid in chamber 160, which fluid passes to the rear brakes through port 162. In the event of power failure valve 126 remains closed, piston 110 acts temporarily as an accumulator piston, fluid from chamber 120 supplying chamber 64 through valve 134 to provide a limited amount of pressure reserve. As this is used up piston 110 is moved rearwardly by spring 112 to raise the pedal. When the operator pushes on the pedal, structure 90 engages " C " washer 94 to carry piston 62 forwardly to pressurize fluid in chamber 74 and consequently in chamber 160 to apply the brakes.

Abstract: 1441040 Mixing apparatus R BADEWIEN 3 Aug 1973 [5 Aug 1972] 36920/73 Heading B1C Apparatus for producing a milk preparation from a milk powder and water, for animals, comprises a milk powder container 1 provided with a stirrer 2, a mixing vessel 5 disposed below the vessel 1 and communicating therewith through a selectively operable valve 4 and provided with a paddle agitator 10, a valve 8 for connection to a vacuum source, and a three-way valve 13 providing for admission of water into, or discharge of milk preparation out of said mixing vessel. A gauge 9 adjacent the valve 8 acts as a milk powder metering device.  In operation, a vacuum determined by the gauge 9 is established in the mixing vessel: milk powder is sucked into the mixing vessel from the powder container, on opening of the valve 4, in dependence on the pressure differential between the powder container and the mixing vessel; water is admitted into the mixing vessel through valve 13; the powder and water is mixed by the agitator 10; and finally the resulting milk preparation is discharged through the valve 13 by excess pressure formed by the water admission. A device 7a signalling excess pressure in the mixing vessel is provided so that said pressure is reduced only to a predetermined residual value so that some milk preparation may be left in the vessel to avoid agglutination. Compressed air from a supply 7b is provided for increasing said excess pressure and for complete emptying and cleaning of the vessel. A nozzle 6 is provided for water cleaning. Milk powder dust in the vacuum line may be cleared by water and compressed air introduced into said line. The stirrer 2 comprises spoked rings 3 covered with wire netting. Upturned air inlet nozzles 12 on the periphery of the powder container provide for air flow parallel to the base of said container to loosen compressed powder. The nozzles 12 may have non-return valves. Several mixing vessels 5, each with a valve 4 may be arranged under a single powder container 1 (Fig. 2, not shown) and may be sequentially operable.

Abstract: 1,023,023. Spraying. BUTTERWORTH SYSTEM Inc. Sept. 27, 1963 [Sept. 28, 1962], No. 36958/62. Heading B2F. In tank-cleaning apparatus in which liquid is supplied by a pipe 3 to a spray head 1, adapted to rotate in a horizontal plane about the axis of pipe 3, and issues through nozzles 9 which rotate about a horizontal axis, the rotations being caused by the pressure of the liquid supply, speed regulation is effected by coupling the nozzles to a driven member 8 adapted to be driven in opposition to the nozzles, by flow of liquid through the by-pass 31, the amount of liquid flowing through the by-pass being varied to maintain the speed constant. The delivery stream may effect the rotation by a motor but as shown rotation is effected by the reaction of jets leaving the nozzles. As shown, the driven member 8 is directly connected to the nozzles but it may be coupled thereto through gearing. The amount of liquid flowing through the by-pass is controlled by a rotary valve 7 which as shown is under manual control but may be automatically controlled either by a governor driven by the nozzles or in accordance with the difference in pressure between the main liquid stream 32 and the by-pass 31.

Abstract: 912,624. Fusible cut-outs. GENERAL ELECTRIC CO. Ltd. Nov. 4, 1960 [Nov. 6, 1959], No. 37713/59. Class 38 (1). A fuse element consists of a flat strip of a high melting-point metal, 1, such as silver, in which a trapezoidal slot, 2, is cut to divide a current into two paths, 3 and 4. A portion of path, 4, is removed and replaced by an insert, 5, of low-melting-point metal such as a tin alloy. Insert, 5, is surrounded by a close-fitting iron ring, 6, and offers a high impedance to a current surge, thereby causing a large current flow through path 3 which fuses, with the subsequent fusing of insert 5. Overload currents cause eddy-current heating of the ring 6, which, together with the direct heating effect of the overload currents, fuses insert 5, causing subsequent fusing of the path 3. Transient overloads will not fuse insert 5, the energy being absorbed in ring 6. Arcing on fusing may be reduced by suitably proportioning the two paths 3 and 4.
