Title: Improvements in gas-cushion vehicles
Inventor: PAGE REGINALD BANNERMAN
IPC: B60V1/00
Filed: 1964-12-16
Abstract: 1,075,745. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. Dec. 10, 1965 [Dec. 16, 1964], No. 51149/64. Heading B7K. An air cushion vehicle is provided with means for reducing dynamic variations in cushion pressure, said means comprising a gas-flow connection between a space occupied by cushion gas and a region of gas at datum pressure and means for directing a curtain of moving gas into said connection so as to control gas flow along the path provided by the connection. A vehicle 1 is supported on a cushion 3 enclosed by a flexible skirt 13 forming a plenum chamber, air being delivered to the plenum chamber through a duct 12 which is formed with a branch duct 19 which connects with a duct 4 leading from the plenum chamber to atmosphere. The duct 19 is formed with a valve mechanism 5 under the control of the pilot whereby the strength of an air curtain (6, Fig. 2, not shown) issuing from duct 19 into duct 4 may be varied to adjust the flow of cushion air to atmosphere through duct 4 in response to dynamic variations in cushion pressure. The duct 4 may exhaust rearwardly to achieve a propulsion effect. In a further embodiment (Fig. 4, not shown) the duct 19 supplies air to an apertured plate (36) which forms an annular air curtain (39) directed around an aperture in the top surface of the plenum chamber, the plate being axially movable whereby the curtain may control the amount of air flowing from the cushion through the aperture. In a further embodiment (Fig. 5, not shown) the cushion is contained by an inflatable skirt (52) which discharges a peripheral air curtain (53) and the cushion pressure control valve comprises a gated device of movable plates (63). In a still further embodiment (Fig. 7, not shown) the cushion is contained only by a peripheral air curtain (82) and the control valve comprises an axially movable bullet (91) within a circular duct (89) which in turn co-operates with a bell-mouth axiallymovable duct (88) extending into the cushion space.

Title: Electronic timepieces
IPC: G04C3/14
Filed: 1975-12-15
Abstract: 1515400 Electronic timepieces DAINI SEIKOSHA KK 15 Dec 1975 [25 Dec 1974] 51266/75 Heading G3T In an electronic timepiece, pending battery failure is indicated by a deliberately excited abnormal advance with time of the seconds indicator. In Fig. 1 embodiment, under normal conditions a stepping motor in a unit 4 receives a 1Hz pulse train from an AND gate 3 via an AND gate 24 and OR gate 27, and advances a seconds hand by 1 sec. every second. However when a detector 28 senses that the output voltage of a battery 5 is below a predetermined value, it blocks gate 24 and opens an AND gate 25 to pass a higher frequency pulse train from an AND gate 22 through OR gate 27 to the motor unit 1. Thereby the seconds hand is caused to advance by five seconds during each successive fifth second, and remain stationary during each intervening period of four seconds. The timepiece includes a crystal controlled oscillator 1 followed by a frequency divider 2. The 1 Hz control signal of pulse width 7.8 m.sec. for the normal motor drive, is derived by summating in the AND gate 3, outputs from the 9th to 15th stages of the divider i.e. at 64, 32, 16, 8, 4, 2, and 1 Hz respectively. To produce the abnormal seconds advance signal, a control pulse generator circuit 11 receives the 1 Hz signal output of divider 2 and produces an output signal (waveform T) Fig. 3 (not shown) having a pulse width of 1 sec. and a repetition period of 5 secs. A gate circuit 6 summates various outputs of the divider 2 and produces from AND gate 10 five pulses of width 7À8 m. sec (waveform J, Fig. 2 (not shown) during the first half of each second (or alternatively may be arranged to occur during each second half second). Each control pulse from 11 of pulse width 1 sec., opens AND gate 22 to pass the pulse train from 6, thus providing a signal (waveform U) Fig. 3 (not shown) comprising five pulses in the first half of each fifth second and no pulses in the intervening four seconds. Alternatively the seconds indication may be advanced by 10 secs. every tenth second. instead of an analogue display (by a seconds hand) a digital electro-optical display, eg liquid crystal, may be employed, the seconds digit thereof being advanced abnormally to indicate battery condition.

Abstract: 1,152,479. Internal shoe-drum brakes. FORD MOTOR CO. Ltd. 22 Nov., 1966 [14 Dec., 1965], No. 52135/66. Heading F2E. In an internal shoe-drum brake the brake shoes 28 and 26 are adapted to be actuated by means of an hydraulic actuator 44 or by a parking brake lever 60 pivoted to the brake shoe 28 at 66 and adapted to actuate the other shoe 26 by means of a link 54, the two shoes being provided with a floating pivot arrangement 36 and a linkage 68 to operate the parking brake lever 60 such that rotation of the parking brake lever 60 with the brake shoes does not cause substantially any movement of the linkage 68 in the direction of the applied force. Fig. 4 shows the arrangement of the linkage which takes the form of a bell-crank lever 68 fulcrumed at 74 on the brake back-plate 14 and provided with a claw-shaped contact surface 80 that engages a contact surface on the edge 82 of the parking brake lever 60. When the vehicle is moved either forward or in reverse the rotational tendency of the drum 18 rotates the shoes 26 and 28 in the same direction to abut whichever shoe is serving as the reaction member against the anchor pin 30 fastened to the brake back-plate 14. The circumferential movement of the parking brake lever 60 means that its contact surface 82 moves circumferentially and causes substantially no change in the radial distance of the contact surface 80 from the axis of rotation of the drum 18. An automatic adjustment mechanism is provided such that, when the brake linings 46 and 48 wear, an adjusting lever 50 is pulled upwardly out of engagement with the teeth of the adjusting screw ratchet wheel 52 and its return movement against the ratchet teeth of the adjusting screw by the spring 53, when the brakes have released, rotates the screw and spreads the adjuster 36 apart to compensate for wear of the brake linings.

Abstract: 1,107,908. Pneumatic sensing. SPERRY RAND CORPORATION. 16 Dec., 1965 [29 Dec., 1964], No. 53449/65. Heading G4M. [Also in Division H1] The operation of pressure switches 22 is controlled by a perforated encoded paper tape 11, which may be of the Chadless type, passing under a pneumatic device comprising a body 14 of V-section provided with a chamber 15 connecting via a pipe 16 to a fluid source, and a plurality of ducts such as 17a, one for each row of perforations (a-f, Fig. 1), each communicating with a pressure switch 22 by a duct 23 provided with a vent 28. Each duct such as 17a has a set-screw such as 18a for varying its resistance to fluid flow. When the duct 17a is blocked by the paper tape 11 pressure in ducts 17a, 23 and a duct (38, Fig. 4, in the switch) connecting to duct 23, causes a diaphragm (37, Fig. 4) in the switch to move a cantilever spring contact (46, Fig. 4) to engage a fixed contact (41). When a perforation passes under duct 17a, the pressure in ducts 17a, 23 (38) is reduced to atmospheric and the diaphragm (37) relaxes and the spring contact (46) moves away from the fixed contact (41) under its spring bias. In an alternative arrangement, the cantilever spring contact (46) may be biased to engage the fixed contact (41). An inert gas may be contained in the part of the switch having the contacts.
