Title: Space coordinate determination - has scanning head moving over varistor capacitor matrix and sawtooth waveform generator
Inventor: KLEINSCHMIDT PETER DIPL PHYS
IPC: G06F3/033
Filed: 1974-09-27
Abstract: Space coordinates in one or two dimensions can be measured by a matrix of capacitors and varistors. A substrate receives discrete T-shaped metallized areas made of a varistor material on one side and a counter-metallized area is applied to the other side. The distances between the T-bars represents the varistors and the legs of the Tees with the counter metallized area represent the capacitors. A scanning head is used to detect the change in the magnetic field. In a one-dimensional scheme, a sawtooth voltage waveform (204) is applied to a line of varistors (1-4) and capacitors (5-9). The currents into the capacitors, when the breakdown voltage of a varistor is reached, is sensed by the scanning head (202) which is a coil with a ring core, separated by an air gap. The sawtooth voltage is produced by the generator (200). A control unit (201) reverses the sense of the sawtooth voltage generator when the current steps have reached it.

Title: Through flow water heater outlet control - has cold water volume regulator responding to temp controlled meter
Inventor: KURZ ROLF ING GRAD
IPC: F24D17/00
Filed: 1974-10-26
Abstract: A process for maintaining the exit-temperature of hot water, especially in the case of electrically heated flow-heaters, is based on comparing the temperature of the hot water, which is adjusted, continuously or intermittently by means of a rated-value meter, with the actual value of the temperature of the exit water. This yields an adjustment-value, which is passed, by way of a regulator-line, to a volume regulator, which increases or decreases the quantity of cold water flowing into the flow-heater, so as to maintain the temperature fixed on the rated-value meter.
Patent DE-2452260-A1 (DE)
Title: Fluorescent lamp synchronous ignition device - is for lamps with initial cathode heating and with ignition by sudden current interruption
Inventor: LANZ OTTO
IPC: H05B41/04
Filed: 1974-11-04
Abstract: The ignition process is initiated by current interruption in a circuit containing the cathode filaments and an inductance. A relay is provided, which carries no current when the mains voltage is switched on. It holds by its contact (S) the circuit between cathode filaments closed, and allows the heating current to flow. A synchronised pulse generator (ST) generates pulses synchronous with the mains voltage, with specified amplitude and width. They charge a capacitor (C) whose voltage is compared in (K) with a reference voltage (Vr), and when this voltage is reached, comparator (K) delivers a signal which opens a gate (T) in series with the relay (R) winding, which operates and opens the contact (S), so that current flowing through the inductance (VD) is interrupted at a specified instant corresponding to the mains voltage zero crossing.

Title: Distinguishing and separating various media - using two or more measurements of physical properties evaluated in electronic controller
Inventor: MUENNICH-DEBUS HERMANN
IPC: B01D17/02
Filed: 1975-05-02
Abstract: System for distinguishing and separating different media involves the measurement simultaneously or in quick succession of two or more physical properties in two media closely associated. These values are calculated in an electronic device and compared with standard values. By this means an exact distinction of two or more media is possible and consequently control instructions can be executed. By the fixing of one or more limiting values, a definite limit is set on the acceptable degree of mixing of two media and this can be determined as above. The system can be used to control the separation of a mixture of two media. Of use for monitoring water streams where the possibility of environmental pollution by oil etc. is a problem. The use of one criterion alone is not satisfactory (e.g. electric or mechanical evaporation, dielectric onstands, density, refractive index, elasticity, viscosity, pH value) to ensure complete definition of the media. However with only small additional outlay it is possible to achieve much closer control by monitoring several properties.

Title: Control circuit for storage heater - reduces power by isolating one phases heating element from others
Inventor: SIMONIS KARL ING GRAD
IPC: H05B1/02
Filed: 1975-08-02
Abstract: The control circuit controls a storage heater that has 3 heating elements one for each phase of the supply coupled together in a full or partial star-configuration and connected to the a.c. supply. The circuit allows either full or half heating power with few components. The first contacts of a control switch or relay are located in one phase line between the supply and that line's heating element. The second contacts of this relay disconnect the neutral line from the neutral point of the star by disconnecting the other end of the heating element. This element is therefore isolated, and the remaining two connected together is series between the remaining two phases.
