Abstract: 1,110,068. Air cushion vehicles. BRITISH HOVERCRAFT CORPORATION Ltd. 23 Sept., 1966 [24 Sept., 1965], No. 40888/65. Heading B7K. An air-cushion vehicle comprises a rigid structure 1 and at least one depending inflatable structure 16 which comprises upper and lower bulbous portions 2. 3, integrally formed by tension members 17, which are extended by tensioning members 5, 6 to restrain lateral movement of the structure 16, and a flexible skirting member 4 which in the embodiment is inflatable (though it need not be) through a conduit 8, 8a. The portions 2, 3 are inflated through a conduit 7 and extension under inflation is resisted by a spring device comprising a fluid spring 10 connected by a tension member 11 to a cable and pulley arrangement 12, 13 whereby the structure may be inflated to a predetermined extension and may deflect under impact as a whole or locally, as over waves when the vehicle is operating as an air cushion vehicle. For operation as a displacement vessel the skirting member 4 is deflated and the portions 2, 3 inflated to a pressure higher than that needed for operation in the cushion mode.

Title: Cameras
IPC: G03B7/081
Filed: 1976-10-07
Abstract: 1530969 Camera exposure control and indication FRANKE & HEIDECKE GmbH [Trading as ROLLEI-WERKE FRANKE & HEIDECKE] 7 Oct 1976 [18 Oct 1975] 41700/76 Heading G2A A camera has a photodiode 3 and integrating capacitor 4 connected to the input of an FET 2 and a circuit 1 connected to the output of the FET 2 and switchable between exposure control and exposure indicating modes. The circuit 1 includes means 18 for charging the capacitor 4 during the indicating mode with a pulsed current opposed to the photoelectric current. The FET 2 has a high input impedance necessary for use with the low currents produced by the photo-diode 3 and a low output impedance enabling conventional switches to be used in the circuit 1. Exposure control mode. Switch 19 is left open. Upon shutter release: (a) a switch 17 closes to charge capacitor 4 according to the setting of a film speed resistor 16. (b) as the shutter starts to open, switch 17 reopens and the photo-electric current charges capacitor 4 to the opposite polarity. (c) eventually, capacitor 4 is charged to a voltage which triggers a switching circuit 27 to deenergize a shutter closing electromagnet 12 and energize an LED indicator 14. Exposure indicating mode. Switch 17 is left open and switch 19 is closed to turn on an oscillator 18. This provides squarewaves which are differentiated by RC member 16, 20 to provide pulses which charge capacitor 4 in the opposite direction to the photo-electric current. Eventually, capacitor 4 reaches an equilibrium voltage. If illumination is too low for a hand held exposure, switching circuit 27 is not triggered by capacitor 4 so transistor 13 stays off and LED 14 is flashed by oscillator 18 via diode 21. If illumination is acceptable, capacitor 4 triggers circuit 27 to turn on transistor 13 and illuminate LED 14 continuously.

Title: Adjusting device for regulating the elevation of vehicle headlamps
IPC: B60Q1/105
Filed: 1974-10-02
Abstract: 1492800 Regulating vehicle headlamps ROBERT BOSCH GmbH 2 Oot 1974 [3 Oct 1973] 42683/74 Heading, F4R [Also in Division G3] The light-range of vehicle headlamps 24, Fig. 1, is automatically adjusted in response to relative movement of the vehicle chassis with respect to its axles by a servomotor 50 connected to the lamps and having valves operated in response to movement of a piston 43 which compares pressure signals from modulators 9, 10 on the front and rear axles. Positive pressure is supplied to the modulators from a source 3 and valves 62, 63 and 66, 67 are closed when equal signals are applied by the modulators to opposite sides of the piston 43, the servomotor being at rest. When axle movement causes a pressure difference and upward movement of the piston 43, and valve 66, 67 opens and air flows from chamber 39 into a chamber 53 to raise the servomotor 50 and pivot the headlamps through a pivoted link 77 and a spring-loaded cable 22. Downward movement of the piston 43 in response to a reversal of the pressure difference opens the valve 62, 63 to allow air to escape from the chamber 53 to atmosphere through a filter 90 and a port 91. The space (153) Fig. 3 (not shown) above the piston (150) may be at positive pressure and the space (154) beneath it connected to atmosphere through a filter (190), the valves (165, 167 and 166, 168) controlling communication between the spaces and between the space (153) and the source of positive pressure having a modified constuction. A construction similar to that of Fig. 3 may be vacuum operated, but with the space above the servomotor (250) Fig. 5 (not shown) connected to atmosphere through a filter so that if either of the lines between the modulators and the piston (238) breaks the headlamps pivot downwardly. A similar result is produced with positive pressure operation by providing a spring-loaded valve 142, Fig. 4, which is normally held open by the pressure in line 15; failure of this pressure causes the valve to connect the space 153 above the servomotor to atmosphere through passages 192, 196 and pivot the headlamps downwardly. Fig. 6 illustrates a vacuum operated embodiment in which the piston 338 responsive to pressure signals from the modulator is firmly secured to a tube 358 arranged to separate from a valve disc 365 on upward movement of the piston and to separate the disc from a bore 356 on downward movement of the piston. The valve disc may be arranged to co-operate with a seat (467) Fig. 7 (not shown) in the servomotor piston (450). Reference has been directed by the Comptroller to Specification 1,333,509.
