Title: Transistorised signal switching circuit - for amplification of square wave signals uses transistor networks and tank circuit
Inventor: KANBERG HORST DIPL ING
IPC: H03K5/02
Filed: 1973-08-01
Abstract: A low amplitude square wave signal may be given to this circuit, and the resultant output will be a signal of similar shape, but smooth and amplified. The input signal is presented to the base of a transistor, whilst the collector of the transistor is fed to a tank circuit, which provides the required output. Thus, the transistor is switched to its 'ON' and 'OFF' states under the influence of the input signal. The output however is arranged, by the tank circuit, to respond to only those changes of a square wave nature and hence a smooth output signal is obtained.
Patent DE-2342805-A1 (DE)
Title: Mains socket with interlocked switch - uses slotted shift-locking plate of socket and interlocking disk to disable switch
IPC: H01R13/707
Filed: 1973-08-24
Abstract: In the mains socket the switch is locked if the plug is not inserted but becomes released after insertion of the plug. By plug insertion a shift interlock is pushed against the force of a return spring and releases the switch action. Operating the switch protects the socket also against being pulled out. This is achieved by means of a locking bolt pressed against a protection catch of the socket. The locking plate carries a guide slot for the shift interlock and a guide slot for the locking cam. An interlock ring pivots on the interlocking plate and has a drive notch for the shift interlock and offset, against this drive notch, a cam penetrating the guide slot for the locking cam. The interlock ring disk is manipulated by the switch. The arrangement works without play resulting in clear locking with acceptable manufacturing tolerances.

Title: Pressure testing system for engine cylinder heads - ensures precise measurement regardless of amount of air leakage
Inventor: SCHLEMMINGER HORST
IPC: G01M3/26
Filed: 1974-05-04
Abstract: Each cylinder head is coupled to a finely regulated air supply and after it has been filled with air to the test pressure it is switched over to the measuring tube of a differential pressure convertor to operate a pressure gauge. During direct filling of the cylinder head, air at test pressure flows through the measuring tube via a separate throttled outlet, whereby the convertor applies an effective pressure corresponding to the air passing through the outlet to the first accumulator of a subtracting relay to drive the gauge. The direct connection between cylinder head and air supply is then broken, and with the first accumulator isolated from the convertor outlet, a second relay accumulator is connected to the latter outlet and the gauge is connected to the relay outlet for the duration of the test.

Title: Vehicle external deceleration indicator - warns following vehicles of braking action violence so that they can keep their distance
Inventor: TIEDT UWE ING GRAD
IPC: G01P15/02
Filed: 1974-12-11
Abstract: The simple indicator is for attachment to the exterior rear of vehicles, which indicates to following drivers the deceleration when the vehicle brakes. This should allow the vehicles behind to maintain a proper distance. The device consists of a mass (7) mounted in a cylindrical chassis by means of a spring (9) in such a way that when a deceleration occurs the mass moves forward in the chassis (1) compressing the spring. As it does so it turns a shaft (6) which is mounted through the centre of the mass and spring. This shaft carries an indicating disc (2) which then turns by an amount dependent on the deceleration and reveals a coloured segment of proportional size to the following driver. The arrangement is lit by a small lamp (14) which directs light at the disc. A mounting arrangement (16) is also provided.
