Title: Method and circuit arrangement for selecting printing elements in matrix printers
Inventor: GUESS KURT
IPC: G06K15/10
Filed: 1982-03-22
Abstract: To reduce loading on the processor and to improve the utilisation of the storage capacity of the character generator (ZG) in matrix printing devices whilst simultaneously improving the typeface, especially when printing characters with descenders, the word width (n bits) of the information required for selecting m printing elements (DE) is reduced (n < m); a selection byte (BT) comprising n = 8 bits contains, in addition to the printing information (BI) at least one identification information item (K), the evaluation of which in the selection circuit of the printing elements (DE) results in a selection of the printing elements (DE) displaced for all or for individual columns (S1 to S12) of the character set in the line direction of the character raster (ZR) or in a selection of a further printing element (DE) (underlining). <IMAGE>

Patent DE-3237627-A1 (DE)
Title: Clamping ring
Inventor: LINNEMANN FRIEDRICH
IPC: F16L23/06
Filed: 1982-10-11
Abstract: The present rapid clamping ring is used for coupling two flanges, especially a small flange vacuum-pipe connection. In this case, a fixed-dimension coupling plate is provided on a lever closure of two half-shell-shaped clamping pieces, which plate is located opposite a connecting plate of the clamping pieces running tangentially on the hinge side. The connecting plate is hinged via hinge pins on both sides of a dividing plane, at end parts of the clamping pieces. The fixed-dimension coupling plate is likewise attached to a hinge bolt on one side of the dividing plane on a head part of the clamping piece. An operating lever with a pivoting bolt is hinged on the other side of the dividing plane, on the end region of the fixed-dimension coupling plate. In the coupling state, the fixed-dimension coupling plate of the lever closure and the connecting plate of the opposite hinge run parallel to one another. Both plates are located in slot-shaped recesses in the clamping pieces. In addition, both plates are designed to be non-adjustable, so that the two clamping pieces are always held at a permanently constant fixed distance from one another, to prevent gaping apart, even when coupling is repeated frequently.

Patent DE-3309939-A1 (DE)
Title: Logging device
Inventor: POLLI CLAUDIO DR ING
IPC: G07C1/26
Filed: 1983-03-19
Abstract: In a logging device, such as, for example, in a carrier-pigeon meter, a plurality of containers which are covered by a cover having an orifice are contained in a magazine. A further orifice in an indexing wheel is brought into coincidence with this orifice, so that a container can be filled with an object, for example with a foot ring. During a rotation of the indexing wheel, the filled container is transported further and a new container is brought under the orifice of the cover. To prevent an object projecting above a container just filled from being jammed between the container and cover, the edge of the orifice of the cover, under which the filled container travels past during its transport, is designed as a pawl, against which the projecting part of the object runs, with the result that the pawl pivots and engages with the indexing wheel.
Patent DE-3314686-A1 (DE)
Title: Device for measuring the area of the projection of a specimen onto a plane
Inventor: KUHN ALFRED
IPC: G01B11/28
Filed: 1983-04-22
Abstract: The invention relates to a device for measuring the area of the projection of a specimen onto a plane. In this arrangement, a light beam projector is traversed line by line over the specimen at right angles to the projection direction, the traversing device being continuously capable of fixing to the position of the light beam in terms of coordinates. It is established with the aid of a sensor whether the light beam passes the specimen and arrives in the sensor or whether the light beam is interrupted by the specimen. In order to be able to save an additional traversing device for the sensor, the sensor is arranged laterally offset with respect to the projector on the same traversing device and is moved along with the latter. Only a matt projection wall on which the light beam passing by the specimen generates a light spot is arranged on the opposite side. The sensor has a telescopic optical system which is aligned precisely on this light spot and is focused onto it. A plurality of sensors can be arranged around the projector in order for the light spot to be perceptible by at least one of the sensors. Such devices are required in order to determine the drag coefficients of bodies enveloped in a flow such as, e.g., vehicle chassis.

Title: Method for optically determining the nature of the surface of solid bodies
Inventor: RIEDER PETER
IPC: G01B11/30
Filed: 1984-03-31
Abstract: In this method, the illuminating light is directed perpendicularly onto the surface to be investigated. The intensity of the light backscattered from the illuminated surface is measured in at least two prescribed directions. The difference of these measured values is used to derive a measure of the inclination of the scattered light curve in the prescribed angular range, which measure is, in turn, characteristic of the overall shape of this curve, which latter is determined by the roughness of the surface. The intensity of the light reflected back in the direction of the illuminating light is used as a measure of the thermal emission. <IMAGE>
