Abstract: 1,194,497. One-way acting brakes. WESTINGHOUSE ELECTRIC CORP. 2 Oct., 1968 [13 Oct., 1967], No. 47000/68. Heading F2E. [Also in Division D1] In a rotary reciprocating agitator washing machine, a hub 36 secured to the agitator 30 is mounted adjacent and axially aligned with a stationary hub 37 and a helical spring fitting over and in frictional engagement with both hubs so that, when torque is applied in one direction to the agitator, the spring tightens to impede movement of hub 36 whereas torque applied in the other direction loosens the spring, one hub having oil escapement portions 38 as the arrangement is in or near an oil bath. The agitator blades 31, which each comprise an inclined plane portion and a vertical wall portion extending along its outer edge, extend round post 29 from base 35 to the top. The agitator has a screw action lifting the clothes when rotated in one direction and sucking them down when rotated in the other. The tub 2 is secured to a sealed oil-filled housing 4 containing gear frame 16, an input shaft 12 and an output shaft assembly 18 with an oscillator inner drive shaft 21 and a unidirectional rotary outer drive shaft to which the hub of rotary basket 26 is secured. Hub 36 is connected to the lower part of frame 16 and, if the reactive torque applied to frame 16 from the agitator causes the spring 34 to tighten, it will arrest angular movement of the frame 16 and force the agitator to perform a full stroke whereas if the torque causes the spring to loosen, frame 16 will be released and the agitator will be retarded by the action of the clothes. Sleeve 37 is preferably made by a powder-metallurgical process, e.g. sintering, and spring 34 is preferably attached to one hub, e.g. 36. Reference has been directed by the Comptroller to Specifications 1,096,366 qnd 1,035,735.

Abstract: 1437389 Determining steering patterns of vehicles HE DORAN 29 Oct 1974 [1 Nov 1973] 50747/73 Heading G1X Apparatus for determining the steering pattern of a vehicle and to enable its movement to be determined whilst turning at full lock comprises a base 5 and a transparent part 6 pivotally mounted thereon for rotation about pivot axis P which is at the common centre of a concentric outer circle 7 and an inner semicircle 8, the circle 7 being graduuated in degrees from 0 to 90 degrees. The inner semicircle 8 is adjacent an ungraduated half of the outer circle 7 and together represent the radially inner and outer extremities of a vehicle turning at full lock, the vehicle being represented by rectangle 9 or 11. The assumed rear axle position of the representation lies on a line between the zero mark and the pivot axis P. The transparent rotary part 6 has a second vehicle representing rectangle 17, or (16) Fig. 3, (not shown), which exactly coincides with that on the base 5 in one angular position of part 6. A line drawn through the assumed rear axle position of the second rectangle is extended so as to enable the relative angular positions of the first and second rectangles to be ascertained. A pair of rectangles may be provided on both the base 5 and part 6 in order to represent turning in both senses. The theoretical line ahead movement of a vehicle may be indicated by lines 12, 13 and/or 14, 15 which define zones which it is assumed must be kept clear. In the position shown, Fig. 1, part 6 has been turned through 30 degrees indicating that a vehicle must be turned through this angle to effect parking. In this position, however, rectangle 17 falls within the zone defined by lines 14, 15 and the front thereof must be advanced to points 18, 19. The area required for parking may thus be obtained for any parking angle by measuring the various distances on the apparatus. A spacer Fig. 4 (not shown) may be provided to allow the measurement of the dimensions required for the placing of vehicles side by side.
