Abstract: 1356177 Assembly form fits ODESSKY ZAVOD PRESSOV 7 Aug 1971 37218/71 Heading B3U Wheels 9 are forced on to an axle 8 by the alternate reciprocation of pistons 11 of a pair of coaxial hydraulic cylinders 10, each cylinder having a feeler rod 13 which is mechanically interlinked with the respective piston and which interacts both with the axle to ascertain the axle length and with a corrector device 22, the latter interacting with the wheel being forced on to the axle to determine the effective length of stroke of the piston to suit the length of the axle. In operation the axle has the wheels preliminarily fitted on to the guide cones of the axle and the assembly is then placed on a carriage 6. The left hand piston is then actuated and moves to the right to centre the left hand wheel on the guide cone, after which the piston causes the carriage 6 to move to the right until the right hand end of the axle rests against the end of a thrust sleeve 12 of the right hand cylinder. Simultaneously a bracket 17 mounted on the left hand piston 11 moves a sleeve 16 along a rod 15. The sleeve acts upon a stop 20, via a spring 19, and moves the rod 15 and feeler rod 13 to the right. The rod 15. pivots a lever 23 of the corrector device 22 to the right thus moving to the right a spindle 25 of a slide block 26 together with a sensor 27. This movement continues until the end of the left hand feeler rod 13 rests against the axle. Simultaneously the sensor 27 stops in such a position that ensures the equivalent distance l from the inner faces of the wheels 9 to the ends of the axle on both sides of the wheel pair. Further movement of the sensor ceases and the left hand wheel is forced on to the axles until its inner face contacts a stop 28 which moves to the right until it contacts sensor 27 whereupon the left hand hydraulic cylinder is deactivated. The process is then repeated for the right hand wheel.

[Also in Division G3] A water mixing valve has identical hot and cold water inlet valves 22, 22a, Fig. 1, each loaded to the closed position, shown, by a spring and the supply pressure; each valve communicates on its downstream side with a mixing chamber 26 leading to an outlet 28 via a restriction in a washer 30. A control chamber is associated with each inlet valve and is divided by a diaphragm 46 into upper and lower chambers 42, 44, the former being permanently open to atmosphere through an orifice 48 whilst the latter is connectible to a vacuum source 54 or atmosphere under the control of a valve 56 which may be manually or automatically actuated; the diaphragm 46 is connected to its associated inlet valve by a rocker 60. Thus, depending upon whether either one or both inlet valves are opened, water is supplied to the outlet 28 at any one of three different temperatures. The upper wall of the diaphragm chamber may be dispensed with. In a modification, the inlet valves are each actuated by a pair of diaphragms 124, 126 Fig. 3, interconnected by a lost-motion means 154, 156 whereby any one of five different temperatures of the outlet water may be obtained. The upper chamber 118 is open to atmosphere whilst the intermediate and lower chambers are connected to a vacuum source 136 or atmosphere by valves 134, 142. By reducing the amount of lost-motion to less than one-half of the complete range of movement of the upper diaphragm 124, as well as providing a stop 200 for the lower diaphragm 126, each valve has two further intermediate positions whereby a range of nine outlet water temperatures is available. The diaphragm or diaphragms may be replaced by bellows of polypropylene plastic. The filter and a flow limiter 48a are provided upstream of each inlet valve. The housing may be formed from a thermoplastic material and the diaphragm means may be secured thereto by spring clips; the lower fixed wall of the diaphragm chamber may be formed by moulding polycarbonate acetal resin, acrylonitrile butadiene styrene, polyvinyl chloride, or cellulose acetate butyrate. A flow-limiting means may be provided in the outlet, the means comprising a flexible member 138, Fig. 16, supported above the outlet pipe 132<SP>1</SP> by a transverse element 134<SP>1</SP> having two pins 136<SP>1</SP> that co-operate with slots 137<SP>1</SP> in the member 138<SP>1</SP>; the latter is held on the element 134<SP>1</SP> by a rod 139<SP>1</SP>. As the flow of water increases the member 138<SP>1</SP> flexes downwardly to progressively restrict the amount of water passing to the outlet. The valves may control the programmed cyclic operation of a washing machine.
