Abstract: 1,179,779. Container traffic vehicle. HAZLEMERE MOTOR CO. (WALTHAM ABBEY) Ltd. 2 Oct., 1968 [26 Oct., 1967], No. 48741/67. Heading B8E. A detachable container body 6 has a downwardly open guide channel 14, a vertical cheek member 18, forwardly projecting forks 12 and a rear locating bracket 24. The body is detachably seourable to a vehicle chassis having crossmembers 5. To detach the body ground engaging struts 37 having wheels 45 have their spigots 39 introduced into a chassis underframe cross-member 28. After screw clamps 29 holding the container on the chassis are released a drive shaft 41, which is connected by dog clutches 42 36 to the strut on the other side of the vehicle, is turned to raise the container from the chassis to allow the vehicle to be driven away. To replace a body the container is supported in an elevated position on its struts 37 and the vehicle having an upstanding guide roller 26 is backed under it being guided by the cheek 18 and guide 14 until the roller is positioned in the rear bracket 24 and projections on the chassis enter the forks 12. The chassis cross-members 5 are now positioned over gaps in the guide 14 and on lowering the struts the container is located to a rest position on the cross-members by pins and holes 7, 8. Screw clamps 29 are then introduced into forked brackets 9 to secure the container in transport position.

Abstract: 1404495 Hydraulic accumulators ROBERT BOSCH GmbH 2 Nov 1973 [4 Nov 1972] 51077/73 Heading F1D In an accumulator in which a gas chamber 5, Fig. 1, is separated from a liquid chamber 6 by a diaphragm 4, all the liquid which flows from an inlet duct 14 to an outlet duct 15 passes through the accumulator chamber 6. As shown in Fig. 2 the liquid flows through a bore 26 into the accumulator and out through a duct 27 except when a resilient valve 29 is pressed over inlet 30 and outlet 31 by the expansion of the diaphragm 4'. When this happens the liquid passes from duct 21 to duct 22 by unseating a ball valve 25. Fig. 3 shows an embodiment in which liquid flows through the accumulator except when a slide valve 37 is depressed by the diaphragm. When this happens liquid passes from inlet 34 into a chamber 36 and out to duct 35. Fig. 4 (not shown), illustrates an embodiment in which a pair of slide valves, operated by the diaphragm, are provided. In the embodiment shown in Fig. 5 liquid flows from an inlet 64, along the inside of a slide valve 68 and into the accumulator through holes 73. From there it passes out through an annular chamber 70 and duct 71. When the slide valve 68 is depressed by the diaphragm, liquid passes directly from the holes 73 into the chamber 70 and out through the duct 71.
