Title: Circuitry for recording re-takes on magnetic medium - whereby corrected section is inserted without gaps or interference signals
Inventor: LEITZ PETER
IPC: G11B27/029
Filed: 1974-02-25
Abstract: The circuit arrangement is designed for use in dubbing films, where it is frequently necessary to replace a short recorded section because of an error by an actor or sound engineer. Problems of synchronisation, interference from switching on ad off and complicated, expensive circuitry are obviated by the invention, where several recording heads and erase heads are used. All the erase heads are connected to the erase current amplifier and all the responsive heads to the pre-magnetising current amplifier switched through a delay section. The switchable amplifiers switch the erase and pre-magnetising currents with an increase or decrease time which is longer than the longest recording period.
Patent DE-2419679-A1 (DE)
Title: Synthetic cellular cushion esp. for bump stops - cell wall thickness increased to give high density cushion
Inventor: SCHWARZ WILHELM DR ING
IPC: F16F1/377
Filed: 1974-04-24
Abstract: The invention provides a cushion made of a closed cell structure synthetic foam which is especially useful for a resilient abutment such as bump stops for cranes, motor vehicle suspensions etc. Known are cellular cushions having a cell wall thickness to cell volume which results in densities in the range 0.3 to 0.7 gms per cubic centimetre. In practise it has been found that such cushions become tired in use so that the graph of resistive compressive force against displacement becomes less steep as time progresses. This can be overcome by increasing the cell wall thickness relative to the cell volume to give a density in the range above 0.75 gm per cubic centimetre and preferably between 0.75 and 0.8. The increase in density also permits a reduction in the dimensions L, d of a given bump stop for the same application.

Title: Pancake coil inductance equalising - uses ferrite powder paste applied to coil conductor to achieve wanted inductance
Inventor: RABL HELMUT DIPL ING
IPC: H01F3/08
Filed: 1974-08-29
Abstract: The equalisation adjustment process is intended for adjusting the inductance of pancake coils and uses a magnetisable paste applied to parts of the coil conductor to alter its inductance in the required direction. The paste contains ferrite powder formed into a paste by adding an organic binding agent that hardens at low temperature, i.e. below 150 deg.C. The ferrite powder may have copper added to it. The advantage of this equalising or adjustment process lies in its being readily automated. It does not affect the coil Q factor and keeps the inductance constant even under changing environmental conditions.
