Title: Improvements in or relating to devices for the brake operation of trailer vehicles or the like
IPC: B60T15/02
Filed: 1943-10-04
Abstract: 578,314. Fluid-pressure brakes. CLAYTON DEWANDRE CO., Ltd., and RODWAY, J. Oct. 4, 1943, No. 16263. [Class 103 (i)] Brake control means comprise a lever pivotally mounted upon a second lever and connected to the pedal and to the control valve of a brake cylinder, the second lever being mounted on a fixed pivot and being connected to a brake operating rod. The brake cylinder may be that of a trailer vehicle and the brake rod may be connected to the tractor vehicle brakes, the arrangement being such that the cylinder pressure or vacuum reacts on the pedal and that the pedal pressure is transmitted through the rod to the tractor brakes. The control valve shown comprises a casing 15 connected at 16, 17 respectively to a vacuum source and the trailer brake cylinder. A disc valve 19 in a chamber 23 formed in a piston 13 is normally seated on the end of passage 16 and the brake cylinder is then connected to atmosphere through recesses at 30 around the valve passage 27 and chamber 14<1>. When the piston 13 is moved to the right the valve 19 seats on a flange 25 of the piston and leaves the passage 16 so that the brake cylinder is cut off from the atmosphere and connected to the vacuum source, the vacuum reacting on the piston and tending to return it. The piston is connected by a link 11 and a bush 10 to a lever 3 which is connected by a bush 4 to the forked end 2 of a rod 1 connected to the pedal. The lever 3 is mounted by a pivot 7 on a pair of levers 8 which are mounted on the fixed pivot 9 and are connected by pivot 5 to the forked end of a rod 6 connected to the brakes of the tractor vehicle. The bushes 4, 10 surround with clearance the pivots 5, 9 respectively. Upon operation of the pedal, the lever 3 at first swings about the pivot 7, the clearance at the pivots 5, 9 being taken up and the valve piston 13 being moved to connect the trailer brake cylinder to the vacuum source. The vacuum in this cylinder reacts through the piston 13 and lever 3 on the pedal and through the pivot 7 and lever 8 on the rod 6 so that force is applied to the tractor brakes equal to the reaction transmitted to the rod 1 and the pedal. If the vacuum fails the levers 3, 8 turn. as one about the pivot 9 when the lost motion has been taken up, so that the tractor brakes may still be applied. The mechanism may be modified for use with fluid under pressure. The rods 1, 6 may be arranged to extend in the same direction.

Abstract: 1465198 Vacuum cleaners HOOVER Ltd 11 April 1974 [17 April 1973] 16266/74 Heading A4P A vacuum cleaner comprises a casing within which is mounted a motor driven main fan which produces, in use, a suction air-flow for cleaning purposes, the air-flow being directed through the motor for cooling purposes and after leaving the main fan, passes to one or more apertures in the casing. Means, for example, auxiliary fan means produces an auxiliary air-flow which mixes with the suction air-flow between the main fan and the aperture(s). As described, the main fan may comprise centrifugal fans 38, 42, although one face 75 of fan 42 may provide a "viscous" fan for inducing the auxiliary air-flow. A further fan 64 in the form of a paddle wheel having radial vanes may be provided to enhance the auxiliary air-flow which enters the casing at intake louvres 24. The two air-flows meet in the volume between baffle 44 and the outer periphery of fan 42, the flows further mixing in passageway 48, chamber 74 and channels 76 before exiting at louvres 22. The fans 38, 42, 64 are preferably mounted in tandem on shaft 72 driven by the motor 28.

Abstract: 278,419. Hutchinson, G. V. V. July 3, 1925. Railway locomotives, internalcombustion and compressed air; driving-gear of crank-type.- Comprises a locomotive propelled by one or more internalcombustion engines which drive an air compressor and are disconnectibly coupled to the driving-wheels, the compressed air being delivered to driving-cylinders permanently coupled to the driving-wheels; these cylinders may be associated with or may be those of an internal-combustion engine or engines permanently coupled to the wheels. In the construction shown in Fig. 1 a combustion engine 2 driving a rocking beam 5 is directly coupled by rods 10 to air-compressing cylinders 7 and by rods 11, friction clutches 13, rods 22, 23, a crank-shaft 18, and rods 24 to the driving-wheels. The compressed air is delivered by the compressor 7 to a reservoir (not shown), find from there to cylinders 32 permanently coupled by rods 36 to the driving-wheels. The rocking. arms 31 are fixed on a rod 30 carrying beams 29 which can be rocked when required by internal-combustion cylinders 27. To start the locomotive the friction clutches 13 are disconnected, the engine operates the compressor 7, and the compressed air is used in the cylinders 32. When the locomotive attains sufficient speed the internal-combustion engine 27 is supplied with fuel, the air cylinders 32 are shut off, the clutches 13 are engaged and the engine 2 and 27 drive the wheels. At the same time the reservoir is re-charged by the engine 2 and when this has taken place the cylinders 7 are automatically prevented from doing any work. If the engine works on a two-stroke cycle the cylinders 32 may be used for scavenging and charging, but if the cycle is a four-stroke one the cylinders 27 may be used both as air cylinders at starting and afterwards as internal - combustion cylinders. Specification 231,604 is referred to in the Provisional Specification.

Two metal members separated by an insulating material deformable by heat are resistance - welded by applying heat to or generating heat in the region of the desired weld, displacing the heated insulating material from the region to permit the establishment of a conductive path between the members through which current is passed. In an embodiment two metal foil sheets 10, 11 coated with, e.g., polythene layers 12, 13, are connected at 16, e.g. by a conductive clamp and electrodes 14, 15, preferably spring-pressed, are applied so that current flows to locally heat the sheets 10, 11 and layers 12, 13. Electrode pressure displaces the layers 12, 13 and welding is effected between the sheets 10, 11. The layers 12, 13 may be fused adjacent the weld. In printed circuit manufacture a polythenecoated metal foil 32 is folded over a baketized paper base 30 and welding as above is effected in an aperture 33 with the foil 31 itself forming the connection 16. Unwanted foil is afterwards removed. As an alternative to passing current through the sheets for local heating the electrodes may be heated. According to the Provisional Specification copper foil polythene coated sheets may be welded by 50-cycle alternating current.
