Patent DE-4015305-A1 (DE)
Title: Wear-resistant reducing roller for e.g. pipe or rod mill - is made by spray-coating individual carbon roller elements with metal alloy while clamped on axial bolt
Inventor: KROLL LEO DIPL ING
IPC: C23C4/18
Filed: 1990-05-12
Abstract: Prodn. of a reducing roller with a wear-resistant surface for stretch rolling mill comprises clamping at least two annular-shaped rounded and circumferentially grooved carbon steel  bodies (1) coaxially together by an axial bolt (3) to form a base element (6,6a) with the bodies being sepd. by spacing disks (2,2a). The base element is then spray-covered with a wear-resistant layer. After cooling, the coated base element (7) is dismembered into the individual roller elements which are then finished to form the required reducing rollers. More specifically the roller elements are heated and recompressed before the finishing process. USE/ADVANTAGE - The rollers can be used for the prodn. of e.g.  not only pipes but also rod steel and wire. Service life of the rollers is improved due to the use of softer base bodies. The prodn. process is facilitated by reducing the number of necessary finishing stages, hence prodn. costs are also reduced.
Patent DE-4030574-A1 (DE)
Title: Load current monitoring circuitry - uses keying ratio monitoring circuit registering actual current supplied by voltage via control or regulating circuit
Inventor: SCHMITT HANS-WALTER DIPL ING
IPC: G01R29/027
Filed: 1990-09-27
Abstract: The monitoring circuit (5) registers the actual current (I) by measuring the actual keying ratio (t) of a voltage (U) across the load (2) presenting an impedance. The actual (t) is compared with a predetermined stipulated keying ratio (Signal S) to derive currfent deviations. The monitoring circuit generates a correction value for the relationship between the keying ratio of the voltage (U) and the current (I) value affected by interference values (St). The latter can be delivered by at least a temp. sensor and a potentiometer. Sensors can monitor the temp. (T) of the load and/or the working voltage (UB). USE/ADVANTAGE - The load can be a pressure regulator. Requires no elaborate analogue amplifying circuits.

Title: Hydraulic pressure point between connecting rod and ram in press - has two telescopic piston-cylinder assemblies tensioned relative to each other against spring
Inventor: SCHROBBACH HENRY
IPC: B30B15/00
Filed: 1991-06-06
Abstract: The hydraulic pressure point with chamber is located between connecting rod and ram of a press, for cutting, deep drawing, or stamping. It also has a hydraulic circuit to generate an initial tension in the chamber. Two telescopic piston-cylinder assemblies (3, 5; 7, 4) are located in the power circuit.

Title: Laser transit-time anemometer detecting very small particles -  uses photoreceiver(s) to detect reduction in power caused by light dispersion when particle passes focus point of laser diode
Inventor: KRAMER RAINER DR
IPC: G01P5/20
Filed: 1991-09-13
Abstract: Quasi-dot-shaped registration of flow characteristic values in optically transparent media is achieved by measuring the transit time of individual particles optically detectable in the stream. At least two beam paths (4,5) are used to produce neighbouring focus points (7,8) at a known distance apart. The focusable light source (1) is pref. provided by a laser diode. If a particle passes through a point of focus it disperses light, reducing the power of the associated beam path. This is detected by at least one photoreceiver (10) intercepting the beam paths. This serves as a start or stop signal for the transit time measurer (13). ADVANTAGE - Allows light intensity at points of focus for detection of small particles to be reduced.

Abstract: In cash registers, it is necessary to safeguard the cash cassette, connected releasably to the cash register and closed by a cover by means of a locking device, both in association with the cash register and in an individual arrangement of the cassette, against unauthorised opening as a result of the actuation of the cassette keypad or the use of a duplicate key. The release pawl 4 for the cover-blocking device is provided with a lever arm 4a which is connected operatively to a blocking slide 5 via a nose 5a. By means of a further nose 5b formed on the blocking slide 5, the movement of the blocking slide 5 and therefore also of the release pawl 4 is blocked in the closed position by the mortice-lock bolt 1a of a mortice lock 1 used additionally. Moreover, the blocking slide 5 actuates a microswitch for the electromagnetic release of the release pawl 4. <IMAGE>
