Patent DE-3122702-A1 (DE)
Inventor: VOLLMAYR NORBERT DIPL ING
IPC: G01R29/02
Filed: 1981-06-06
Abstract: A method and apparatus for determining the phase angle between two periodic square wave signals is disclosed in which the two square wave signals are applied to respective inputs of an exclusive OR gate, the output signal of which is applied to a first input of a digital selection circuit. The output signal generated by this digital selection circuit is passed through a low pass filter to form a time integral, arithmetic mean value which is digitized by an analog to digital converter and supplied as a numerical value to a digital computer. The digital computer applies logical signals to two additional inputs of the digital selection circuit. The computer is programmed to sequentially set these control signals such that the digital signal presented to the computer sequentially represents the mean value, an upper signal level value, and a lower signal level value of the square wave signal output by the selection circuit. The computer is programmed to use these three variables to calculate a corrected value of the phase angle and to display this calculated value on a display unit.

IPC: H01M4/52
Filed: 1981-07-24
Abstract: A preparation process, which does not use washing water, for nickel(II) hydroxide as a positive-electrode material in button cells bypasses the conventional precipitation from Ni salt solutions, filtration and drying of the hydroxide precipitate, by reacting NiSO4 or Ni(NO3)2 in solid form or from a highly concentrated solution with a small amount of NaOH to give Ni(OH)2. The reaction (1), cf. figure, is repeated in further process stages (3, 5, 7) to completeness, the aqueous sodium hydroxide, which is passed through the process stages in the opposite direction with respect to the progress of the reaction, being polluted least in stage (7) and most heavily in stage (1) with the by-products of the reaction (Na2SO4). In each of the process stages (2, 4, 6, 8) a separation of the Ni(OH)2 from the lye takes place by expressing (pressing out). The pure end product can be processed into electrode pellets while still moist with lye. <IMAGE>

Title: X-ray examination device
Inventor: SCHMIDT ARTHUR
IPC: G21K1/02
Filed: 1981-09-29
Abstract: The invention relates to an X-ray examination device for the preparation of X-ray recordings in accordance with the slotted diaphragm recording process (Slot technique). In such X-ray examination devices, the X-ray film is protected against scattered radiation by a slotted diaphragm which is close to the film and travels therewith. In order to achieve protection against radiation in any position of the slotted diaphragm, the slotted diaphragm must have twice the width of the maximum film format; this leads to recording devices whose width is of undesired magnitude. To this end, the invention provides that a radiation-impermeable blind (22, 23) is secured in the adjustment direction on both sides without any gap to the slotted diaphragm (21) close to the film. In addition, a respective separate blind (22, 23) can be secured at both sides of the slotted diaphragm (21) close to the film, and the two ends of the two blinds can be connected to one another on the rear surface of the image base (18) with interposition of tension springs (29). An X-ray examination device according to the invention is especially suitable for application in X-ray diagnoses. <IMAGE>

Title: Garage for motor vehicles
Inventor: GENZOW F CHRISTIAN DR
IPC: E04H6/06
Filed: 1981-12-17
Abstract: Garages for motor vehicles are normally built at the side of a dwelling house on level ground. In many cases, the erection of a garage at the side of the dwelling house is undesirable or not possible, for example because access to the land lying behind is thereby prevented or made difficult, or because windows of the dwelling house would thereby be covered, or for other reasons. To create a garage which is not normally visible to the outside, it is proposed to provide in the ground a completely embedded pit, the dimensions of which correspond to a conventional garage and in which a platform receiving the motor vehicle is arranged in such a way that it can be lifted and lowered between the bottom of the pit and the surface of the earth by means of a lifting apparatus, and which is covered by a closing plate in the lowermost position of the lifting apparatus.
