Patent DE-2623395-A1 (DE)
Title: Float switch for liquid level control - has shaft with diametrically opposite magnets and rotary motion producing polarity change
Inventor: LUEHN OKAR
IPC: H01H36/02
Filed: 1976-05-25
Abstract: A float switch which is used for level control or a similar function. It consists of a shaft with two diametrically opposite magnets. They are mounted opposite the switching armature, with magnets. The pivoting motion of the magnets is produced by a magnet fitted to the float. The effect of the rotary motion of the magnets compared to the armature magnet produces a change in polarity thereby causing the switch armature to produce a contact changeover. The polarity of the magnets mounted diametrically opposite on the shaft are the same and will determine the position of the switching armature.

Title: Implanted heart pacemaker control pulse transmitter - has control signal converted for serial transmission without external interference
Inventor: TEICHERT WERNER DIPL ING
IPC: A61N1/372
Filed: 1978-01-27
Abstract: The control signal transmission system for an implanted heart pacemaker, uses a transmitter outside the patient's body. This supplies a digitally coded control signal representing a required operating mode, which is transmitted in serial form. The transmitter has a signal converting circuit, receiving the digital control signal and providing a signal such that in a reference signal sequence, each reference signal is followed by a further signal with a variable time lag after it, this time lag representing part of the information contained in the digital control signal. Each further signal can have one or two possible time lags, each corresponding to one bit of the control signal. The serial transmission of the control signal prevents inadvertent actuation of the switch etc. controlling the pacemaker operating mode.

Inventor: BESSON RENE
IPC: G04G9/00
Filed: 1978-02-15
Abstract: A method for the display of information by means of a multi-element passive display device, the elements being separately activated, matrixially arranged and at least two elements required to be activated for display of information. The type of display involves use of a liquid crystal cell formed of electrodes and counter-electrodes carried by two glass plates respectively and the said elements are parts of said electrodes and counter-electrodes. The method comprises the election for activation of elements which are adjacent in any direction, that is, either those superposed, or side by side or diagonally arranged. This method enables use of conventionally shaped characters of greater individual size than heretofore available and is useful for display of dates and/or days of the week on electro-optic watches.
