Patent DE-2736373-A1 (DE)
Title: Load cell with protected transducer - has force divided into main flux transmitted via steel springs and secondary flux via springs and transducers
Inventor: FABIAN WOLFGANG DIPL ING
IPC: G01L1/26
Filed: 1977-08-12
Abstract: The load cell comprises a transducer in which the main force flux is divided into a primary and a number of secondary force fluxes. The main fluxes are transmitted via components having as high a modulus of elasticity as possible, for instance, steel (3, 4, 5). The secondary force fluxes are conducted by spring components (6, 7) and load transducers (8, 9). All the components are placed between an upper and a lower support plate (6, 7). The spring components are constructed from a material having a low elastic modulus. The strain paths in the main and secondary force fluxes are the same, but there is a lower specific strain force in the secondary force flux and thus less loading of the cells. This form of construction means that shock or non-uniform distribution of force on the surface of the transducer will not damage it.

Title: Remote control circuit for switching first stage load - uses second stage load current which operates relay through several components, which connect first stage load
Inventor: BAUDER GERHARD DIPL ING
IPC: H02P5/74
Filed: 1977-08-19
Abstract: The switching-on is performed by the current consumed by a second stage load plugged into the first load. The circuit consists of load resistors (RL) across which a voltage drops when the second stage load (M2) is started and of a voltage comparator (OP1) the oscillating rectangular voltage of which is rectified by a diode (D3) and smoothed by a capacitor (C3). There is a series resistor (R2) through which the smoothed voltage excites a transistor (Tr1), which applies current to the first stage load (M1) through a make contact.

Patent DE-2819192-A1 (DE)
Title: Induction heating of metal workpieces without scaling - in furnace contg. gas filled tunnel, and suitable for heating steel pieces prior to forging
Inventor: STANGL ERNST
IPC: C21D1/74
Filed: 1978-05-02
Abstract: A conveyor is used to drive the workpieces through a gas filled tunnel in an induction furnace. The tunnel slopes upwards towards its outlet end, from which the hot workpieces are removed, and the angle (gamma) of slope of the tunnel is adjusted, to create a chimney effect compensating by the increasing temp. of the workpieces in the tunnel. The pref. induction furnace is fitted with feet of adjustable height on its outlet end, and pref. also a hood restricting the rapid exit of gas from the tunnel. The arrangement prevents a drop in the pressure of the protective gas near the outlet of the tunnel, and therefore decreases the amt. of scale formed, e.g. on steel billets being heated prior to entering a forging press.

Title: Recording damage on moving film or bands - using infrared scanning and pen recorders or warning devices
Inventor: SIROWATKA KARL
IPC: G01N21/89
Filed: 1978-05-19
Abstract: A device determining, recording and counting mechanical damage on moving bands or films involves contactles scanning by infra-red light. The damage is recorded both in its vertical position and horizontal extent. This is achieved more quickly than with conventional methods. Neither the photographic content of the film being tested nor the ambient light intensity affect the measurement results. The scanning device can be connected to a counter or warning device. Continuous monitoring may be achieved using a multiple channel recorder. A single channel recorder can be used with a switching unit.

Title: Automatic hand towel dispenser incorporating laundry system - has extra deflectors ensuring smooth crease free passage of towel lengths
Inventor: BEITECKE BERND
IPC: A47K10/30
Filed: 1978-06-21
Abstract: The hand towel dispenser has a built in washing system. The supply chamber (8) containing the used towel lengths and the supply container (9) containing the freshly laundered towel lengths each has a deflector (26, 27). These project into the path of movement of the drawn-out length of towel (4). This deflector ensures that when the towel moves, i.e. a fresh length is drawn out, the used length is returned to the housing, and follows a curve so that no folds can occur. Shaft-like passages (28, 23) can follow on from the deflectors as a further measure.

Patent DE-2911417-A1 (DE)
Title: Detachable load assembly for truck - has spindle operated locking claws on chassis
Inventor: PAUL JOSEF
IPC: B60P7/13
Filed: 1979-03-23
Abstract: A truck with detachable loads has the underside of the load gripped by two sets of claws on the chassis, with the claw operation controlled by a spindle drive operated by a crank wheel outside the vehicle. The spindle alters the relative spacing of the two sets of claws and thereby opens and closes them over the locking pins under the load. The system is simple and effective. It provides a secure hold for the load on the chassis, with the claws moving to lock onto the load, without requiring accurate positioning of the load. The load is raised from the chassis using integral lifting struts.

Title: Medical monitor raster display smoothing circuit - has sampling circuit and requires max width equal to twice separation between parallel paths
Inventor: ADLEMAN GEORGE LEONARD
IPC: G09G1/16
Filed: 1979-10-03
Abstract: The raster lines of the cathode ray tube are the paths along which the patterns are formed, the signals of the first set that successively increase the width of the contrast pattern and the signals of the second set that successively decrease the width of the contrast pattern must occur in sequence as the beam is scanning along the raster line or path, but when the raster lines intersect the path, the signals in the two sets of signals occur a line scanning interval apart. The signal for any intersection is the same in either case, but the time of occurrence differs. In either case, a signal calling for a particular width at a particular point along a path must be available to control the spot size of the electron beam when it arrives at that point, whether it is scanning along the path or transverse to it.

Title: Kineto-diode-direct conversion of thermal to electric energy - using screening, braking and relays preventing electrodes
Inventor: GIESE PETER DIPL ING
IPC: H01J45/00
Filed: 1979-12-10
Abstract: Thermal energy is converted directly into electrical energy by a kineto-diode-direct converter. The kinetic energy, transferred from a hot ribbed well to monoatomic positive ions is braked in an electric field and transformed to potential energy. The ion displacement between two capacitive field electrodes effects a capacitance change and an inversely proportional voltage change. The braking electric field is produced by the phase shift between the ion flow and the lagging charge compensation by the electron flow. Collecting electrodes ensure the retention of arrested ions for the rest of the containment time. The calculated efficiency of the new conversion system is 80-90% compared with 12-15% for thermo-ionic and thermo-electric conversion.

The structure gives a material with good liq. absorbence, but which can be squeezed dry easily, with long life through high mechanical stability.
