Title: Pressure cooker safety valve adjustable load member - is controlled according to pressure inside vessel preventing too sudden release
Inventor: KRAUSPE WILHELM
IPC: A47J27/092
Filed: 1977-05-14
Abstract: The safety valve mechanism is designed as a locking device which can be controlled by the pressure of the medium which is monitored by the safety valve (8). It locks the actuating member (6) of the load mechanism (7), the resetting movement of the load device being coupled to the pressure-controlled resetting movement of the locking device. The load device for the safety valve can thus be easily set to a higher value before or even during use and as the pressure increases, the locking device is moved towards its end position, each position corresponding to the pressure prevailing at that time. It the maximum pressure set has still not been reached, the load device can be set back until the actual and theoretical values of the pressure coincide. Resetting the load device can only be undertaken in dependence on the pressure prevailing. The element of danger is avoided because the safety valve cannot be released too quick'y which could lead to a spurt of very hot liquid.

Title: Low-loss switching circuit for clocked power supply - has transistors coupled in parallel without negative feedback and driven into saturation
Inventor: NOESKE DETLEV
IPC: H02M3/00
Filed: 1978-12-06
Abstract: The switching circuit consists of several low-power transistors connected in parallel and always driven into saturation. The transistors are not specially selected for the job, operate without a negative feedback, and are located in a shared housing. The switching circuit can handle currents up to 100 amps., and switching frequencies of between 20 and 100 kHz, whilst having a low collector/emitter voltage drop and high current gain (e.g. 40). The power loss is thereby limited to roughly 0.1 watt per ampere of collector current. Heat sinks can be omitted, as can be emitter and base resistors preventing a thermal runaway. Circuits handling different currents can be realised simply by altering the number of transistors coupled in parallel.

Title: Imitation wood furniture parts etc. - by casting polyurethane foam into a mould lined with a pigmented reversal coating
Inventor: LOHOFF GEB FREITAG MARIANNE
IPC: B44C3/04
Filed: 1979-02-08
Abstract: Imitation wood parts for furniture and panelling are made by casting a polyurethane foam compsn. into a mould lined with a thin layer of a reversal coating and allowing the moulding to cure. Mould lining is such that on removal from the mould, the moulding has an integral surface layer having the colour and structure of wood. Mould is e.g. of metal, or a silicone rubber casting made from a piece of wood. Reversal coating is comprised e.g. of colour pigments, an organic polymer or precursor (esp. with active H atoms to react with the hardening polyurethane) and an organic solvent. Process allows excellent imitations of natural wood parts to be made. In contrast to previous processes in which a sepn. wax was applied to moulds before making the moulding, no sepn. wax is used in the present process, so that this does not have to be removed before further processing of the parts (e.g. by lacquering). Imitation wood parts are esp. useful for interior fittings in caravans.
