Patent DE-3037955-A1 (DE)
Title: Mfr. of apertured plate for heat exchanger - involves forming rows of apertures in shape of involute curve in each plate blank
Inventor: FORBES MURRAY KEMBALL
IPC: F28F1/32
Filed: 1980-10-08
Abstract: The method of mating apertured plates for heat exchangers involves forming rows of apertures in each plate. Each row, when considered as commencing on a radial vector extending from the centre, is the locus of a point moving angularly away from an initial position on the vector. The angular distance from the initial position on the vector of each aperture in each row varies as the distance of that aperture from the centre varies. The rows of apertures are formed in the plate blank on respective involute curves generated from the same base circle.

Title: Prime mover with magnetism and lever action - uses number of electromagnet groups to form ring of groups operating on single axis of rotation
Inventor: BECKER OSKAR
IPC: H02K53/00
Filed: 1980-10-14
Abstract: The prime mover and current generator is based on a combination of magnetism and lever action that is specif. achieved by means of, firstly, a large rotary plate or a long lever arm and, secondly, that the externally supplied excitation current taken into the group of electromagnets is interrupted at the time when the discrete magnets of one group of magnets are at the apex of those sliding past one another. Any number of electromagnet groups can be used to form a ring of magnet groups that specif. function in common on one axis of rotation. More specif. any number of rings of electromagnet groups can operate around a single axis of rotation.

Title: Automatic radio clock adjustment
Inventor: HILBERG WOLFGANG DR ING
IPC: G04R60/00
Filed: 1981-01-17
Abstract: Radio clocks must be driven under very variable environmental conditions. The distance from the transmitter, interference signals from the environment, screening and directional effects can assume very large or very small values depending on the installation location. In the known radio clocks, a dimensioning which just fulfils all the necessary conditions in the complete range is chosen as a compromise. It is proposed in the application to configure the circuit such that it automatically itself adjusts the most favourable reception. An essential part of the invention is the proposal to extract the effective signal-to-noise ratio as assessment scale in this case. Such an effective signal-to-noise ratio is produced by comparing the ideal pulse shape with the pulse shape actually received, and can be stored as a number in a microprocessor. It then serves, temporarily delayed, as the basis for improving the receiving setting, and will, as a rule, lead after a few iterations to an optimum receiving setting. Radio clocks which are equipped with such an automatic adjustment can be produced in a uniform fashion and yet always be driven in the optimum receiving range, and this also means, e.g. that the clocks can also be used at a relatively large distance from the transmitter.

Title: Laminated material and use thereof
Inventor: WAHLE HANS-EGGERT
IPC: B32B15/08
Filed: 1981-04-25
Abstract: The invention relates to a novel laminated material with an insert consisting of a metal foil. Such laminated materials are suitable in particular for sealing electrical equipment, electrolyte capacitors, accumulators, batteries etc. To improve the adhesion of the metal foil to the thermoplastics and the other layers, the foils are incipiently etched in a chemical bath.

Title: Vehicle member and holding device with openings, and screw connections, for guiding and for mounting a safety belt fixture with a belt in a vertically adjustable and movable manner
Inventor: WEBER AUGUST
IPC: B62D25/04
Filed: 1981-04-29
Abstract: The invention or innovation serves to improve safety belts and thus safety in motor vehicles in the case of rear-end collisions by enabling a vertical adjustment of the safety belts to the desired or safest and most comfortable height arrangement, to fit the respective body size of the vehicle occupant or occupants, without keys by means of manual actuation quickly and without difficulty. This occurs according to the invention in the following way: the vehicle members (1) have several or one, for example, slot-like opening (2) in which the screw connection (3) with the belt fixture (5) located on it is displaced in terms of height only by means of manual actuation and is held in the respective height position by means of one or more magnets (11). The vertical mounting can also take place, for example, by a, for example, knurled screw (8) being screwed loosely or tightly by means of manual actuation. <IMAGE>

Title: Device for articulating a pivoting wing on an adjacent constructional part
Inventor: GRAP SIEGFRIED
IPC: E05D3/18
Filed: 1981-06-04
Abstract: In a device for articulating a pivoting wing, especially of a door or window, on an adjacent constructional part, having two pins which extend at a distance from and parallel to one another through a connecting member which they pass through and of which one is assigned to the pivoting wing and the other to the adjacent constructional part, it will become possible to connect the pivoting wing to the other constructional part in such a way that it pivots through more than 180 DEG  about one of the hinge pins and at the same time can be held securely in the respective position. This becomes possible in that there is fixed to the pivoting wing an abutment face (31) which is parallel to this and which projects approximately radially from the pivot axes (11) of the latter and which, in the closing position of the pivoting wing (1), bears against an abutment face (28) on the pin (6) of the adjacent constructional part (2), in relation to which its abutment face (38) is relatively movable on its pin (6). At the same time, members or hinge wings (7, 8) having the abutment faces (28, 31) will be assigned to the connecting member (4) which is designed as a block plate with recesses (10, 13) receiving the pins (6, 11). <IMAGE>

IPC: B60B33/06
Filed: 1981-06-16
Abstract: Living furniture with a base, in particular heavy wall units, cupboards, bookcases and the like, could previously only be moved using very great effort or working time. By means of the understructure of the countersinkable underframe for living furniture, this heavy work can be done in minutes without applying force. The underframe is made to extend by means of an air pump. It is now simple to move a heavy item of furniture. When the air has been let off, the underframe disappears in the base. The countersinkable underframe for living furniture can be used in the joinery trade, furniture industry and accessories retail trade.

Patent DE-3200353-A1 (DE)
Title: Method and circuit arrangement, particularly for temperature measurement
Inventor: ARTYMIAK DIETER DR ING
IPC: G01K7/20
Filed: 1982-01-08
Abstract: The invention makes it possible to detect a temperature with high accuracy within a wide range of variations. The aim was to carry out the determination of the measurement values without further calibration effort and largely to avoid the disturbing influences on the measurement value determination. According to the invention, a constant voltage is applied for a short time to a series circuit consisting of a series resistor, an end-value resistor, a sensor at measurement temperature and a sensor at environmental temperature. The part-voltages necessary for determining the measurement value are transferred in numbers of pulses. Measurement value and end value are normalised to one another. After denormalisation at the sensor characteristic normalised to the same end value, the measurement value can be specified. The invention can be used whereever temperatures are to be determined accurately and within a wide range of variations, for example in process measuring technology and in automated process technology. Other industrial/physical quantities can also be detected by measuring techniques after other suitable sensors have been inserted.
