Title: Capacitor plastics cover cap - receives sealingly capacitor contact rags and has cable bushing for moisture-proof connection
Inventor: KUNERT WERNER
IPC: H01G2/10
Filed: 1974-01-30
Abstract: The plastics cover cap for capacitors is intended to provide protection against creep currents caused by humidity condensation.

This provides airtight welding of the current terminals and prevents removing of the cap from the capacitor. In order to facilitate mounting the cover cap in semi-finished state may have slits in one or several planes.
Patent DE-2413500-A1 (DE)
Title: AM broadcasting system with (de) coder - uses single sideband modulation, compatible with double sideband receivers
Inventor: DAVIES JACK L
IPC: H04H1/00
Filed: 1974-03-20
Abstract: Two different programmes can be transmitted over the two amplitude modulated sidebands. The coding at the sender consists of modulation of the two independent sidebands with the same amplitude and phase of a first programme signal component and also with the same amplitude, but opposite phases of the other programme signal components. The signals are decoded in a single sideband receiver after separate demodulation of sidebands, so that signal components of one programme are derived by adding the demodulation signals of both sidebands. In order to derive signal components of the other programme, one of the sidebands is inverted and added to the second sideband demodulation signal.

Title: Built-in cooker unit for fitted kitchens - has lift-up work top cover which also acts as fume extractor hood
Inventor: BILLIAN HERBERT
IPC: A47B77/08
Filed: 1974-03-28

The hob is designed to the adjustable in height and thus drops down when out of use so that the work top lies flush with the adjoining work tops. The work top-vapour extractor hood can be designed to fold back at an incline or to be raised vertically. The hob can be mounted above the oven in which case the extractor work top can remain in the cover position above the hob but still act as the extractor.
Patent DE-2416864-A1 (DE)
Title: Pelletizing pan support - has adjustable angle on triangular tiltable structure pivoted near pan discharge end
Inventor: BERG ROLF DIETER
IPC: C22B1/24
Filed: 1974-04-06
Abstract: A pelletizing pan with an adjustable angle of inclination is supported in a base frame with a pivot close to the discharge end of the pelletizing pan. The structure carrying the pan bearing consists of an inclined member, fixed to the base frame end near the pivot, and of an inclined strut, fixed to the other base frame end where lifting, lowering and indexing devices are provided. This creates a pelletizing pan which is easy to adjust in angle of inclination. The lifting devices are relieved of load once the angle has been chosen. The stresses in the structure are a minimum and changes in angle of inclination do not vary the height of drop of the discharged pellets.
Patent DE-2418907-A1 (DE)
Title: Current supervision of relay circuit in telephone installations - involves diode which bridges inductor and rapidly establishes current
Inventor: NIEDERGESAESS DIETER
IPC: H02H3/12
Filed: 1974-04-19
Abstract: Electronic fast acting supervision of the current flow in the inductive circuit is performed by measuring the voltage drop across a series resistor. When the circuit is closed the current cannot be immediately established in the inductor, for example a relay coil, and the electronic supervision would interpret this as a fault condition. A diode, typically a zener diode or specially selected silicon diodes, is connected across the relay coil. On closure of the circuit the applied voltage immediately establishes normal current through the diode circuit whilst the current in the inductor climbs to its rated value at a rate determined by the circuit time constant. The zener or diode forward voltage is slightly higher than the volt drop across the relay coil at rated current.
