Title: Brick drying with opposed variable air flows
Inventor: BEHRENS HEINZ
IPC: F26B21/02
Filed: 1969-09-16

Title: Automatic melt level controlling device
Inventor: VIESSMANN KLAUS DIPL-ING
IPC: B22D11/18
Filed: 1970-01-10
Abstract: Automatic stepwise regulation of the flow of molten metal from a bottom pouring ladle or similar into a continuous casting mould, so as to obtain a constant ferrostatic head in the mould, is based on the measurement of the height of the melt level in the mould and its deflection above or below a preset value.

Patent DE-2265090-A1 (DE)
Title: Injection mould closure cylinder - is pressure regulated as function of mould opening movement under injection pressure
IPC: B29C45/80
Filed: 1972-07-31
Abstract: A device for measuring the magnitude of the mould opening movement in an injection moulding machine comprises an electrical, mechanical, electromechanical, hydraulic or pneumatic movement meter connected by an instrumentation line to a regulator. This regulator operates an adjustment mechanism (pressure-limiting valve) if the measurement falls below or exceeds the limits of a tolerance range for the distance between the half moulds. The adjustment mechanism modifies the mould closure force e.g. for the next injection cycle. Pref. a measuring rod attached to the moving mould support plate cooperated with a measuring head. As the mould is injected the distance between the moving mould support plate and the measuring head increases fractionally. If the increase exceeds a permissible value the measuring rod and head transmit a signal to the regulator and the pressure limiting valve is opened slightly. This increases the hydraulic pressure in the mould closure cylinders for the next cycle.

Title: Low-resistance, solderable noble metal coatings - for piezoelectric or ferromagnetic ceramics using layers of gold with top layer of silver
Inventor: BASTIUS STEFAN DIPL-CHEM
IPC: H01L41/29
Filed: 1973-07-10
Abstract: The process of coating piezoelectric or ferromagnetic ceramics consists of the following steps: (a) application of the Au paste or prepn. to the ceramic; (b) firing at 500-600 degrees C.; (c) repetition of (a) and (b) until the requires surface resistance is obtd.; (d) application of a silver prepn. on the final gold layer to form a solderable top layer; (e) firing the Ag layer at 500-600 degrees C. The existing methods of vapour deposition or application of gold prepns. only gives a thin layer with the danger that Ag ions from the top coat of Ag may diffuse into the ceramic; ths danger is obviated by the present process.
Patent DE-2344752-A1 (DE)
Title: Counterflow cooling system for power cable - returns coolant in counterflow tube inside forward flow tube of power cable
Inventor: FALKE HENNING DR RER NAT
IPC: H01B7/42
Filed: 1973-09-01
Abstract: In the cooling system of power cables the cooling agent circulates in a closed circuit via heat exchangers. The cooling agent is returned in counterflow through a cooling tube contained inside the power cable. The counterflow tube may be of synthetic material, aluminium, or copper. The advantages are that the max. temp. in a cooling section is lower than the temp. prevailing in a system with separate outside return flow. The highest temp. in a counterflow cooling section lies not at the ends of the section but in between.
