Title: Vehicle washing apparatus
Inventor: KAMIYA NOBUYOSHI
IPC: B60S3/06
Filed: 1970-02-11
Abstract: 1299293 Vehicle washing apparatus TOYA ENTERPRISE KK 11 Feb 1970 6571/70 Heading B7J [Also in Division G3] A vehicle washing apparatus includes a travelling frame 14, a substantially horizontal brush 1 carried between two arms 2 and rotated by an electric motor M 1  mounted on one of the arms, means M 2 , 6, 7 for moving the brush towards or away from a vehicle being washed in response to the load on the motor M 1 , and a pair of carriers 5 which support the brush 1 and arms 2 and move vertically relative to the frame. The arms 2 carrying the brush 1 are rigidly secured to a rod 3, the ends of the rod being pivotally mounted in the carriers 5. The movement of the carriers up or down the side wall 4 of the frame is effected by a reversible motor M 2 , chains 6 and sprockets 7. The motor M 2  is controlled as follows: if, as the brush moves towards the vehicle surface, the load on the motor M 1  exceeds a predetermined value the voltage across a resistor 9 is detected by a circuit SC comprising a variable resistor 10 and an amplifier 11, and a signal is fed to a relay 12. This causes switches C 1 , C 2 , which can assume two positions engaging contacts a, a 1  or b, b 1  and which connect the field coil 13 of the motor M 2  to its D.C. power source, to switch over, thus reversing the polarity of the current supplied to, and hence the direction of rotation of, the motor M 2  and resulting in the brush moving away from the vehicle surface. This causes the load on motor M 1  to fall below the predetermined value, detection by the circuit SC ceases and the contacts return to their original position, thus the brush executes an oscillating movement. In an alternative embodiment the relay 12 is controlled in response to the voltage across the terminals of the motor M 1 ,

Title: Improvements in clamping devices
Inventor: ARNOLD FRANZ
IPC: B25B1/10
Filed: 1968-02-09
Abstract: 1,155,804. Workpiece vice. F. ARNOLD. 9 Feb., 1968 [9 Feb., 1967], No. 6620/68. Heading B3B. A workpiece vice has its movable jaw moved to clamp a workpiece by means of a hollow spindle 5 which is threaded into a screwthreaded bore in a stationary portion of the body of the vice, and an axially movable thrust rod 11 which extends from the free end of the spindle 5 to engage the movable jaw. The movement of the thrust rod 11 to clamp a workpiece is achieved by operating means that include a torque override clutch and a thrust multiplier so that initial clamping of the movable jaw is caused by rotation of the hollow spindle 5 in the said screw-threaded bore, until the clutch slips, whereupon a direct thrust upon the thrust rod 11, via the thrust multiplier, finally clamps the workpiece. The vice is operated by a handle 18 rotating a screw-threaded spindle 13 which drives, through clutch 22, 12 the hollow spindle 5 via sleeves 5a, 5b. When resistance to tightening reaches a certain value the movable clutch member 22 slides axially against spring 25 to disengage inclined dog teeth carried by the clutch member 22. Further rotation of the handle 18 and spindle 13 screws the spindle 13 axially through the fixed clutch part 12 to push a primary pressure member 26 to operate, via a hydraulic thrust multiplier 28, a secondary pressure member 27, which urges the thrust rod 11 on to the movable vice jaw. On rotation of the handle 18 in a reverse direction to release a clamped workpiece, friction between the hollow spindle 5 and the said screw-threaded bore prevents the hollow spindle 5 from rotating while the parts of the clutch rotate relatively to re-engage. The hydraulic thrust multiplier may be replaced by a toggle linkage thrust multiplier (38), (39), (Fig. 6, not shown) operated by a cone or wedge (26a).

Title: Improvements in or Relating to Rotary Piston Machines
Inventor: FELLER FRITZ
IPC: F01C19/04
Filed: 1968-02-13
Abstract: 1,182,097. Rotary piston machines. ROLLSROYCE Ltd. Feb.13, 1968, No.7019/68. Heading F1F. In a rotary piston machine having a piston 10 that revolves in a planetary manner within a housing upon an eccentric carried by a rotatable shaft, at least one axially extending groove 26 is provided in the piston, the or each groove containing a sealing strip 28 that is pressed against the inner peripheral surface 17 of the housing by a leaf-spring 30 and the pressure of the working fluid communicated to a space 31 from either a working chamber A or a working chamber B. The or each strip is at liberty to rock about an axis substantially parallel to its longitudinal axis and is furnished with a plurality of slots 46 to give the working fluid in the chamber A access to the space 31 when due to friction at the surface 17 and the pressure in the chamber B being less than a predetermined value the strip occupies a first position as shown in Fig. 2, direct communication between the chamber A and the chamber B being prevented by contact between the strip and a step 56. When the pressure in the chamber B becomes greater than that in the chamber A and sufficient to overcome the friction aforesaid, the strip assumes a second position as shown in Fig. 3 so that the working fluid in the chamber B has access to the space 31 while being prevented from entering the chamber A due to contact between the strip and the wall 50 of the groove. The size of the portion 58 of the strip above the step 56 determines the pressure in chamber B at which the strip is moved to the second position. In one modification, Fig. 7 (not shown), the step is formed in the strip in instead of the wall 52 of the groove. In another modification, Fig. 8 (not shown), the step is extended to intersect the periphery of the piston adjacent the chamber B. In yet another modification, Fig. 9 (not shown), a portion of the strip overlaps the step so that the pressure of the working fluid in the chamber B urges the portion of the strip above the step radially outwards. The machine may be a pump, compressor or internal combustion engine and be of the trochoidal n and n + 1 lobe type with a three sided piston wherein one of the before mentioned sealing strips is lodged at each apex, Fig. 1 (not shown).
