Abstract: 966,135. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. Oct. 5, 1960 [Oct. 16, 1959], No. 35163/59. Heading B7K. A vehicle 1 which, in operation, is supported above the surface over which it operates by at least one cushion of pressurized gas, has at least one projection 2 depending below the bottom of the vehicle and bounding a space 3 beneath the vehicle, means, e.g. a motor-driven fan 8, for supplying gas under pressure to at least one supply port 4 situated on one side of the projection 2, at least one recovery port 6 situated on the other side of the curtain through which a flow of gas is induced, the gas flowing beneath the projection forming and containing, with the projection 2, the cushion of pressurized gas, at least part of the gas then flowing into the recovery port, the vertical cross-section of the projection for at least that part of its periphery associated with each recovery port being such that the gas flowing beneath the projection at that part of its periphery is constrained to follow the profile by Coanda effect, the recovered gas recirculating through the means 8 for supplying gas under pressure. The arrangement of Fig. 3, which is a transverse section, is a preferred embodiment but other arrangements are described. Instead of the central air intake shown the intake may be horizontal and forwardly directed so that air enters partly by ram effect. The duct 5 through which the recovered air re-circulates to the fan may carry an adjustable shutter whereby the flow may be regulated and a similar shutter may be placed beneath the port 4. The projection 2 may be mounted for upward pivotal movement or it may be inflatable and supplied with pressure fluid. An arrangement is described in which the fans are located at the periphery of the vehicle for rotation about horizontal shafts located in horizontal supply ports. A still further embodiment discloses the base of the vehicle compartmented by three separate annular recovery ports each surrounding one or more fans and supply ports.

Abstract: 640,305. Sliding doors. WIGELAND, A. R:, DOKKEN, J. N., and ANDERSEN, C. A. Dec. 31, 1947, No. 35387. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 8, 1948.] [Class 20(iii)] A supporting device for a sliding door,. which operates to lower the door, as it closes, onto the floor, consists in one or more wheels from each of which a segment has been removed, the radial extension of the segment corresponding to the required lowering of the door, the periphery of each wheel being greater than the width of the door so that the wheel does not perform a full revolution when the door is moved from one extreme position to the other. A sliding door 1 is supported on two wheels mounted on a frame housed within the bottom rail, each wheel having a segment removed and the position of the wheels being adjusted relative to the position of the door in the doorway so that when the door is closed the flat part 5 of their peripheries engages the floor, the bottom rail of the door consequently fitting closely to the floor. When the door is opened the wheels first tilt to raise it from the floor and then roll on the curved part of their peripheries to carry the door to the open position. The portion 6 of each wheel is removed so that the remaining portion exerts a balancing action which aids the lifting of the door when opening and retards its downward motion when closing. The wheel hubs may be connected by a rack (Fig. 3, not shown) which maintains them in constant relative angular position and a buffer (Fig. 5, not shown) may be provided to smooth the downward motion of the door.

Abstract: 1348931 Grinding NORTON CO 2 Aug 1971 [3 Aug 1970] 36182/71 Heading B3D [Also in Division G4] A machine for automatically grinding a succession of workpieces rotates each workpiece in a headstock W and footstock (not shown) and a rotating grinding wheel 30 is advanced on a slide 20 driven by screw and nut 42, 28, which screw is itself driven via a worm gear 54, 56. The shaft of the worm is driven by an electric stepping motor assisted by an hydraulic motor, although a single electric motor or an electrically controlled stepping hydraulic motor could be used instead. An hydraulically operated piston 36 acts on the screw to move the gear-wheel and slide assembly by a predetermined amount upon initial start up of the machine. Thereafter the wheel is cyclically advanced and retracted by the stopping motor under digital control (see Divisions G4-G6). The advance of the grinding wheel is slowed down when the workpiece nears its final size which is determined by a first set of feeler gauges and eventually reversed when the workpiece does achieve its final size as determined by a second set of feeler gauges, the control system permitting the workpiece to round up after each feeler gauge has operated. Failure of either feeler gauges to operate at their respective expected times causes the digital control system to come into play and slow the motor down and eventually reverse it.
