Patent DE-2710261-A1 (DE)
Title: Adaptor plate for junction box - consists of plastics moulding with system for snap fitting onto support rail
Inventor: MUENSTERER HELMUT
IPC: H02B1/052
Filed: 1977-03-09
Abstract: The adaptor plate (12) is typically a plastics moulding with elastic properties in the part which fits over the support rail (14) for the box assemblies. In this way the plate grips the rail, once it has been snapped into position, in order to locate the boy (14). The box is attached to the plate (12) by means of screws. Typically the plate has predrilled holes (15) matching the tapped holes in the base of the box. The hole pattern is usefully such that the box can be mounted along or across the rails (14). The form of construction only necessitates clamping the plate to the box, the less accessible operation of clamping it to the rail being replaced by the snap on feature.

Title: Suction hood for heavy duty cleaning purposes - has air cyclone produced by tangential inlet and outlet pipes
IPC: B08B15/02
Filed: 1977-07-16
Abstract: The air inlet pipe (13) to the suction hood (1) is mounted tangentially in one direction whilst the suction pipe (12) is mounted tangentially in the other direction to produce an axial air vortex inside the hood. The cylindrical suction hood can be placed on the axial stump (10) of a brake unit (11) to be cleaned by means of a sleeve (6) which is axially mounted in the centre of the hood and can be displaced by axial force. Centering of the hood thus takes place automatically whereupon the hood is then moved back so that the unit to be cleaned sealingly adjoins from the inside the sealing lamellae (4) which are centrally mounted round the front opening of the hood. The compressed air used for cleaning together with the dust is drawn off through the outlet pipe with the air cyclone. The suction hood can be fitted onto a mobile chassis which provides the link with the vacuum cleaner.

Title: Diagnostic and therapeutic stimulating appts. for paralysed muscles - has pulse generating circuit with changeover switch, generating periodical pulse trains of opposite sign with DC zero compensation
Inventor: EICHHORN KARL-FR DR ING
IPC: A61N1/36
Filed: 1979-03-03
Abstract: The appts. is also used for generating controlled movements of disabled musles. It has several electrodes, applicable to the patient's skin, possibly over an intermediate layer of suitable substance. The electrodes are supplied by a circuit generating suitable pulses of stimulating current. The circuit has a change-over switch (5) of such an arrangement that, after a preset train of unipolar stimulating pulses and a preset interval a train of identically long stimulating pulses can be generated, however, with opposite sign. The arrangement is such that the d.c. mean value of the stimulating pulses, supplied to the patient, is compensated to zero. Pref. after each stimulating pulse of a given polarity, a pulse of opposite polarity follows after adjustable interval with current-time compensation. These ambipolar stimulating pulses may be modulated with a medium frequency carried signal by multiplication in such a manner that alternating pulse blocks, corresponding to the ambipolar wave form are generated.
