Patent DE-2644580-A1 (DE)
Title: Precision measuring instrument for high voltage - has electron beam accelerated by measured voltage and deflected by control system
Inventor: HEINZERLING JUERGEN DR
IPC: H01J37/248
Filed: 1976-10-02
Abstract: The electron beam continuously strikes a given point of a divided detector electrode to which a sum-and-difference amplifier is connected. This amplifier is used to regulate continuously the electron beam deflection representing a criterion for acceleration voltage. The electron beam can be deflected electrostatically. There can be a magnetic field generated by a deflecting current. The electrostatic deflection can be compensated by an adjustable magnetic field. The deflecting voltage is preset as reference and the high voltage is controlled directly.

When the printing is to be commenced the assembly is swivelled back into position.
Patent DE-2652885-A1 (DE)
Title: Ozone generator air drying system - using quickly exchangeable desiccant container for easy regeneration
Inventor: BACHHOFER BRUNO
IPC: C01B13/10
Filed: 1976-11-20
Abstract: An air dyring system for the ozone generators of water treatment automatics has each generator coupled to an easily detachable container, filled with a desiccant which can be regenerated. When exchanged with a container of regenerated desiccant, the spent desiccant is inserted into a regenerating station. This avoids the costly maintenance of built-in air dryers which also increase the purchase of the plant. In case of trouble, conventional dryers may pass water droplets which cause the glass dielectric discs in the ozone generators to crack; this is also eliminated.
Patent DE-2656103-A1 (DE)
Title: Chemical surface treatment of metals in closed circuit - using evaporator to recover water and chemicals from rinsing tanks
IPC: C23G1/36
Filed: 1976-12-10
Abstract: Metal objects are subjected to chemical surface treatment (I) by spraying or immersion, followed by multi-stage rinsing in which the rinsing water flows in counter-current to the objects. In the novelty, the water from the first rinse is fed to an evaporator, from which the vapour flows via a condenser to the final rinse as pure water, whereas the overflow from the evaporator leads to treatment (I). Chemicals and water corresp. only with the net usage are fed continuously or at intervals to the process. Water from the first rinse may be fed to treatment (I), the latter feeding the evaporator; or the water from the first rinse may be fed to the evaporator and the overflow from the latter fed to a reservoir to which chemicals and water are added and the soln. then fed to treatment (I). The pref. plant consists of a closed circuit including an evaporator and condenser, the evaporator being connected in any of the three ways listed above. Recovery of chemicals and water is obtd., so there use is minimal; no decontamination plant is needed to treat effluents. The process can be used for chromate treatment of Mg objects.

Title: Display for power network or generator synchronisation signals - using signals transmitted from measurement site in three different ways, depending on degree of non-synchronisation
Inventor: LEIBOLD HELMUT ING GRAD
IPC: G01R29/18
Filed: 1977-06-16
Abstract: Signals for the synchronisation and parallel switching of generators or power supply networks are detected at a measurement site and transmitted to the receiving site through a delaying remote control system. voltages and frequencies to be compared are converted at the measurement site into analogue voltage, frequency and phase angle differences and transmitted to the remote control receiver at the reception point. When large, non-synchronisable differences are present, three segment-like represented coarse angle signal ranges are transmitted. When quickly synchronisable differences are present, the coarse angles are transmitted, together with stepped angles. The selected information is transmitted as digital signals, and reconverted in a processing circuit into signals controlling display units.

Title: Telephone system preventing anonymous calling - uses sender transmitting subscriber's number to called extension for display and acknowledgement before handset can be used
Inventor: SCHANTZ HERRMANN
IPC: H04M1/57
Filed: 1977-06-16

Each successive gear train in the series provides a stepwise increase in output speed. A final output defines a gear operably associated with one gear of the last compound planet gear of the last compound gear train of the series. The final output gear is rotatable around the fixed shaft and attachable to an output device.

Title: Pressure mounted mesa thyristor device - has pressure plate arrangement to prevent deformation of cathode layer
Inventor: TSUJI ISAMU
IPC: H01L29/744
Filed: 1977-12-23
Abstract: The Mesa semiconductor device comprises an n-p-n-p structure with side walls protected by a silicon rubber layer. The anode is bonded to a carrier plate (80) which in turn is soldered to a terminal plate or clamping plate (84). This plate is attached to a piston. A flat metal plate is placed over the top faces of the Mesa cathodes (70a-d), the width of the plate being at least that of the distance between the outside edges of the outermost cathodes. Pressure is then applied to the plate so that the central area of the semiconductor is deformed inwards. The pressure applied is between 300 and 450 kg/cm2. However, the cathode layer sections are not deformed by this method of construction and no short-circuit can occur between the cathode and the gate.

Title: Membrane:less aluminium air cell with neutral electrolyte - pref. uses ammonium chloride soln. or sea water contg. citric acid as electrolyte
Inventor: RITSCHEL MANFRED DIPL PHYS
IPC: H01M12/06
Filed: 1978-04-29
Abstract: In an Al-air cell with neutral chloride soln. as electrolyte, the air electrodes are not sepd. from the anode compartment by a membrane. The electrolyte pref. contains 0.5-5 (3-4) mole/l NH4Cl and 1-20(3-10)% citric acid. Sea water or a salt soln. of similar concn. is also suitable. Al with a purity of 99.9% can be used. It is also possible to use highly active Al alloys (Hg, Cd, Zn, In, Ga, Th, alkali etc), in which case the current output is increased by adding salts with oxidising anions, pref. (NH4)2SO4, to the electrolyte. The electrolyte is used in large excess and the cell is open to this vol. The theoretical charge density is higher with a neutral, rather than acid or alkaline, electrolyte and the addn. of a complexing agent (e.g. citric acid) keeps the Al in soln. and allows operation without a membrane. Suggested uses are for emergency current supplies for offshore drilling rigs, ships, rescue boats etc. and current supplies for radio buoys, electric motors etc.
