Title: Automatic parking and safety brake for vehicle - with shut-off valve to isolate wheel cylinders under pressure
Inventor: WELTER HELMUT
IPC: B60T17/18
Filed: 1973-05-09
Abstract: An electromagnetic control valve is positioned between the master brake cylinder and the wheel brakes and is open with no current in its coils. When connected to the electric supply it allows fluid to flow to the wheel cylinders but not back to the master brake cylinder, so that the wheel cylinders lock when the pedal is pushed. The valve is connected to an electronic control circuit which incorporates a centrifugal switch, driven by the engine/transmission. This enables the driver to secure the vehicle at traffic lights and road junctions without having to pull up the bandbrake and without having to keep his foot on the brake pedal. The brake is connected to an anti-theft switch so that it locks the wheels if the doors/bonnet/boot lid are opened, with a hidden immobilising switch. For busses it can be connected to the door mechanism to secure the bus at bus stops.

Title: Radar type speed and distance measuring appts. - uses synchronous demodulation of signals between vehicles
Inventor: REITBERGER PETER DIPL-ING
IPC: H04B11/00
Filed: 1973-07-13
Abstract: A radar type position and speed detection system between vehicles using synchronous demodulation, employs a combined receiver and transmitter in each vehicle, and the acoustic signal from the first vehicle is varied, then is reflected back from the second vehicle after further variation. Thus the first signal may be modulated by a factor of e.g. 4/3, then the received signal may be modulated by the reciprocal of the first factor then transmitted back tot he first vehicle, thereby reducing feedback between transmitter and receiver. The system may employ microphones, making use of the phase difference of their received signals.

Title: Rotating cutting tool for formation of soil cores - by pull operation - has central shaft for holding cutter and enclosing concentric shell
Inventor: ATKINS STANLEY GORDON
IPC: E21B7/26
Filed: 1973-08-01
Abstract: The cutter is used especially in soils which exert markedly strong suction effect on the soil column to be excavated and in soils which are relatively loose or porous. The cutter has means for compacting the cut soil in order to reduce the suction effect and for facilitating the removal of the material. The boring tool has a central spindle whose both ends, are threaded. This cutter unit can be connected to an excavating machine. A hollow tapering sheet is held by radial ribs on the shaft. The f ront end of the cutter is narrower than the rear end. The front end of the radial ribs has a number of cutting teeth. Cutting teeth are also arranged around the air open edge of the shell at the narrower end. The core is cut by the circumferential teeth and the core formed is cut up by the teeth at the end of the radial rib. The suction effect in the borehole is reduced by the cutting edge at the wider rear end of the shell.

Title: Spring-assisted handbrake for vehicles - has tension spring in handle acting on double lever with roller following cam surface
Inventor: SCHROETER HANS O
IPC: B60T7/10
Filed: 1974-01-23
Abstract: The tension spring housed in the hollow brake handle is anchored at one end in the handle, at the other end on the extreme point of a two-armed lever with a pivoting point on the extended lower part of the brake handle. The other extreme point of the two-armed lever carries a roller, which, under the influence of the spring tension follows closely the curve of a cam surface shaped in such a way that at the relaxed brake position the spring tension is strongest. When the brake handle is pulled backwards in order to put on the hand brake, the two-armed lever under the influence of the spring tension in conjunction with the shape of the cam produces brake handle.
