Patent DE-2940918-A1 (DE)
Inventor: SIGG HANS
IPC: G01B7/00
Filed: 1979-10-09
Abstract: A measurement head (6) is fastened to the bed (5) where the components (4) are located and measures the position of the lower active surface of the rotating grinding wheel (1) with respect to the bed, providing a measurement with respect to the same reference where the components are located. The measurement feeler (601) of the head (6) directly feels, with sufficient force, the visible surface of the rotating grinding wheel (1). The contact surface of the feeler is made from a hard material, and the head comprises a means capable of damping out vibrations in the measurement feeler, it being possible for this means to be a hydraulic damper, a dry friction damper whose frictional force is either less than or greater than the measurement force, or a mechanism with irreversible effect. The measurement circuit comprises a memory device (8) storing the signal corresponding to the lower positions reached by the feeler. <IMAGE>

Title: Prepd. background for later painting esp. by amateurs - uses printing ink with affinity for chalk pencil paints or dyes
Inventor: RICKERS CARL
IPC: B41M3/00
Filed: 1980-09-19
Abstract: A prepd. background for painting, decorating, hobby painting and the like is produced by printing a design, using as ink a substance which has a different retention capability for later applied colours from that of the uncoated zones. Specifically for dry pigments such as coloured chalks, pencils, carbon etc., a slurry of granular material and binding agent is used, which when dried provides a rougher surface than the uncoated areas. Used in particular for preparing a background for the later application of dry pigments, such as coloured pencils, chalks, pastels, carbon and the like; for this purpose a bonding agent is used, a powder being applied just before the painting or chalking is carried out to increase the roughness of the background. The method is simple for the prepn. of the background and results in less work and skill being required of the final user.

Title: Refining steel with lightweight volatile scavenging agents - in form of compressed body having controlled dissolution rate to reduce smoking
Inventor: DUNN JUN EDWARD JEROME DR ING
IPC: C21C7/064
Filed: 1980-11-11
Abstract: Steel is refined by immersing in the melt a refractory covered vertical rod having a consumable body on its end formed of a pressed mixt. of an active substance having limited solubility in the steel e.g. Ca source, and an inactive material e.g. Fe, Al or alloying elements. The rate of dissolution of the body is controlled by appropriate choice of compsn. and shape so that active substance is released at a rate which does not exceed its solubility limit. The active material may be Ca or an alloy thereof e.g. CaSi, CaMnSi, CaSiBa, CaSiBaAl, CaC2, CaCl or Mg. The inactive material may be Fe, Al or elements which will alloy with the steel. The smoke normally associated with such methods is reduced or eliminated.

Patent DE-3101539-A1 (DE)
Title: Microwave cavity module of sandwich design
Inventor: KLIR VILEM
IPC: H01P7/06
Filed: 1981-01-20
Abstract: Microwave cavity modules (transmitter modules, receiver modules and transmitter/receiver modules) are at the moment produced using the following manufacturing methods:     1) die-casting method,   2) assembly from rectangular waveguide(s)   3) module which is split once. These methods are either very labour-intensive or are associated with high initial costs (such as the die-casting method). These problems are overcome according to the invention in that the microwave module is of sandwich construction. As Figures 1 and 2 show, the microwave module is constructed such that the outer plates (1 and 3) also represent the holders (sockets) for the microwave diodes, and the centre plate (2) has one waveguide resonator in each case for the transmitter section and the receiver section. In consequence, this module can be produced very economically, for example in the case of a 24 GHz module, by stamping from a 3 or 4 mm thick aluminium profile or by profile milling. Even relatively small batches can be produced very cost-effectively with this construction. In addition, it is highly flexible: a change in the operating frequency requires only that the centre plate, which represents the microwave circuit, be changed. <IMAGE>
Patent DE-3106510-A1 (DE)
Title: Mechanical open-ended spanner
Inventor: KLOECKNER ARNOLD
IPC: B25B13/46
Filed: 1981-02-21
Abstract: The mechanical open-ended spanner is used for releasing or tightening polygonal screws or nuts. It remains on the screw during the entire screwing operation and undergoes a type of idling when pulled back against the screwing direction. Hooks (A) which can only tilt forwards (+x) are made in the inner sides of the spanner head (see Fig. 1) of half-round shape. These hooks are kept constantly upright or are pressed (-x) against the screw by springs (B). If pressure is exerted in screwing direction (+y), the screw is squeezed from several sides between the hooks so that it sticks in the mechanism and turns with it. If the spanner is moved against the screwing direction (-y), the hooks tilt away forwards (+x) and slip over the screw. The main possible use is in all technical areas where nuts or screws have to be tightened or released. The invention is used in particular in the case of screws which are difficult to reach and are provided with a long threaded part or are damaged ("turned half-round"), since these labour-intensive screwing operations are considerably reduced. <IMAGE>

Title: Circuit arrangement for an electromechanical taximeter which can be set to a number of tariffs
Inventor: JAUCH GUENTHER
IPC: G07B13/08
Filed: 1981-07-11
Abstract: This taximeter involves the addition, controllable via the tariff selection means, of different time-dependent units for calculating a fare from time and/or distance units. For providing time units for calculating fare units, frequency-determining elements (38, 58) with different pulse frequences available at the output are in each case provided for the different tariffs (T1 to T4). The selection and allocation of a frequency for driving a stepping motor (31) is effected via a logic (53), the inputs of which are acted upon, on the one hand, by the state of the positions, controlled by a tariff selection means, of the switches (S1 to S4) and, on the other hand, the frequencies provided at the output of the frequency-determining elements (38, 58). At the output of the logic (53), finally, the clock frequency for the time units, allocated to the selected tariff (T1 to T4) is available. Application: the circuit arrangement is used for generating, selecting and feeding tariff-dependently different time units via a stepping motor into the fare-indicating mechanism of a mechanical taximeter. <IMAGE>
