Title: Improvements in water-borne gas-cushion vehicles
Inventor: COCKERELL CHRISTOPHER SYDNEY
IPC: B60V1/00
Filed: 1965-04-06
Abstract: 1,135,768. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 5 April, 1966 [6 April, 1965], No. 14615/65. Headings B7A and B7K. The cushion of a waterborne air cushion vehicle is formed of steam generated by evaporating some of the water over which the vehicle travels. The water may be heated by radiant heat, for example from a series of parabolic reflectors 6, e.g. of stainless steel one behind another forming plenum chambers, with a heating element 13 at the focus of each reflector, the heat being supplied by liquid sodium-potassium from a nuclear reactor 8. In a modification (Fig. 3, not shown), there are two rows of reflectors (21), and the adjacent parts of side-by-side pairs are joined to form single surfaces. At least the rearmost plenum chamber communicates with rearwardly directed pipes 16 for forward propulsion, the thrust being controlled by valves. The vehicle may have flexible skirts (24, Fig. 4, not shown) different parts of which can be raised and lowered for manoeuvring by hydraulic actuators (25). The heating elements may be shielded by, for example quartz to prevent the build up of salt on them. Instead of heating elements, lasers (55, Fig. 7, not shown) may be arranged to direct their beams at the water through holes in the vehicle bottom. The frequency of the emission is arranged so that only the surface is heated, and the electrical power is supplied by an M.H.D. generator or by a nuclear powered turbo-generator (58, 57). The water may alternatively be heated by conduction, either by scooping water (76, Fig. 8, not shown) on to heating elements (65) during forward motion, or by pumps (80) directing water on to the elements, or by immersing the heating elements, either as part of a hydrofoil (120, Fig. 9, not shown), or (at 35, Fig. 5, not shown) in sidewalls (34). The sidewall vehicles (Figs. 5 and 8, not shown) have a rear opening through which the steam escapes to propel the vehicle; this opening can be closed to facilitate starting by a shutter (33 or 63) operated by hydraulic actuators (46, 66) and steam is drawn from the plenum chamber by a compressor (42 or 72) to a slot (49, Fig. 6, not shown) in front wall (33) which may be raised and lowered by an actuator like the rear shutter (33). In the embodiment where water is scooped on to the heat exchangers (Fig. 8, not shown), starting is facilitated by generating the cushion initially from a compressed air reservoir (77) and by driving the vehicle by marine screw propellers. In another embodiment steam is raised in a steam generator heated by nuclear reactor coolant, and the steam is discharged into the plenum chamber through an ejector to entrain ambient air. In another embodiment water is sprayed in atomized form towards a heating element, and evaporates before contact with the element.

Title: Interrogation of remote stations
IPC: G08C19/00
Filed: 1971-05-13
Abstract: 1402986 Selective signalling KENT METERS Ltd 4 May 1972 [13 May 1971] 14638/71 Divided out of 1402987 Heading G4H [Also in Division H4] In a remote reading system a computer coupled to a telephone system is arranged to dial out to a remote substation, to transmit a selected code characteristic of a particular response required from that substation and upon reception of that response to transmit a further code to that substation or to dial a further substation and transmit a code thereto. In the preferred embodiment described a plurality of computers or interrogators located in public exchange systems communicate with a central data processor at a supply office and with remote readers located at the substations of consumers and arranged to minotor meters for oil, water, electricity and gas. The communication links between the interrogators and the central processor may be telephone links or direct lines. The interrogators set up connections to the substations by automatic impulse diallers. The code transmitted to the substations may be sent in serial or parallel form using frequency shift or multi-frequency techniques. Various forms of the interrogators and remote readers employing integrated circuit techniques are described. According to the Specification ringing tone is suppressed and the substations do not loop the line. Throughout a connection to a sub-station a first tone characteristic of the meter to be read is continuously transmitted by the interrogator and a tone detector in the substation turns on the power (derived from the telephone line) to the substation equipment. In some embodiments this tone is divided in frequency at the substation to provide an answer tone, these embodiments transmitting one element of a binary coded meter reading in respons to an interrogation tone controlled by timing circuit in the interrogator. In other embodiments each substation equipment includes an oscillator which provdes both the answer tone and stepping of the answer read-out equipment. In all embodiments the answer is transmitted at least twice for security. The substations also transmit the subscribers account number derived from a strapping field. The equipment may be fabricated from large scale integrated circuits. Conventional speech calls using a substation are given priority over the remote reading connections, each substation equipment monitoring its line voltage and releasing a remote reading connection whenever the voltage drops below a given level, e.g. due to the substation looping the line.

Title: Improvements in and relating to servo braking apparatus
IPC: B60T13/06
Filed: 1930-05-13
Abstract: 348,380. Brakes. DORMOY, J. M. J., 23, Rue d'Athenes, Paris. May 13, 1930, No. 14718. Convention date, May 14, 1929. [Class 103 (i).] Actuated by running axle ; actuated by speed regulators.-In brakes operated by a driving member of the vehicle by means of a clutch or coupling member operated by the brake pedal, the operation of the clutch is regulated automatically in accordance with the braking force developed by the driving or driven member independently of the movement of the rigging 13 connected to the braking elements. The brake pedal 16 is connected to a floating lever 9, one end 15 of which operates the clutch 6 through a link and lever mechanism 18, the other end 10 of which is connected by a chain 8 to a pulley or toothed wheel 7 driven by the disc clutch 6. The lever 9 is pivoted on a lever 11 mounted on a fixed pivot 12 and connected to the brake rigging 13. Effort on the brake pedal is transmitted partly directly to the brake rigging through levers 9, 11 and partly to operate the clutch. The pull produced by the clutch on the chain 8 and the end of the lever 9 assists the application of the brake and also tends to rotate the lever 9 in a clockwise direction and thus diminishes the pressure between the clutchplates and regulates the braking force produced by the driving member and produce a regulating couple to minimize the effects due to variation of the coefficient of friction between the discs of the clutch. Lengthening of the arm 10, 14 of the lever 9 reduces the amplification of the braking effort of the discs but increases the stability of the braking action. Springs may be interposed in the connection between the pedal and the clutch. In a modification applied to the change-speed box of a motor vehicle a lever 18 pivoted on the clutch shaft has rollers 19 engaging a face cam 21 concentric with the clutch shaft. This cam on brake operation displaces the lever which causes through the intermediary of a ball bearing 22 the clutch discs 1 to engage. The cam may be rotated to adjust the distance apart of the clutch discs, and the idle stroke of the pedal. The pedal may be connected by hydraulic transmission to the mechanism. Centrifugal masses may be associated with the clutch, which nullify the action of the clutch when the mechanism to be braked becomes stationary. These masses may be located in the disc 1.
