Title: Composite mould for integral-foam mouldings prodn. - has tightly-joined mould-part edges and control elements for predetermined mould-part gaps
Inventor: SENDLER KARL-HEINZ
IPC: B29C44/58
Filed: 1976-03-06
Abstract: Mould for prodn. of mouldings of integral foam comprises several mould components whose edges are tightly pressed together. The contact faces of the gaps are held as narrow as is practically possible. Elements for controlling the pre-determined gap spacing are associated with the gaps. The construction eliminates or minimises "flash" formation on the mouldings so that post-machining and/or de-flashing is unnecessary. Close control of the spacing between mould parts ensures complete filling of the mould when being charged with foamable material. This results in efficient venting of the mould during foaming so that prodn. of mouldings with undesirable voids is prevented.

Title: Remote indication of switch position - using transducer polarity change to alter bistable circuit state
Inventor: WILZECK MANFRED ING GRAD
IPC: H02J13/00
Filed: 1976-09-11
Abstract: The remote indication or switch position is achieved by means of a transducer whose primary winding is connected across the switch contacts through limiting resistors, and whose secondary winding is connected across a capacitor and an amplifier. The amplifier in turn operates a bistable circuit. If the switch changes state then, depending on the polarity induced in the secondary winding, the capacitor voltage is changed in a specific direction. this change is amplified and causes the bistable element to take up a new position which can then be indicated as a change in switch position. The amplifiers and bistable units associated with the various main circuit switches can also be used to fulfill control functions, for example to decide switching sequences.

Title: Electric soap dispenser with automatic soap delivery - utilises change in electric or acoustic field caused by approach of hands
Inventor: TIEFENAU HELMUT DR
IPC: A47K5/12
Filed: 1976-09-30
Abstract: The switch mechanism works on the basis of one electrode being stored in the apparatus whilst the other electrode is formed by the hand located at earth potential. As the hand approaches the sensitive part of an oscillation circuit the timer is started which actuates the soap pump for a preset time. The start of the timer also starts a second timer which as the timer is switched off prevents a restart for several seconds. This avoids any undue delivery of soap or misuse. The switch mechanism only responds to the rapid movement of a hand in an electric or acoustic field and not to very slow movements such as condensation.
