Title: Temp.-measuring method based on barrier layer, semiconductor component - deriving temp. from differential inner resistance of component initiated by biassing voltage
Inventor: RIGAUER REINHOLD ING GRAD
IPC: G01K7/01
Filed: 1979-08-31
Abstract: The temp. measuring procedure depends upon a barrier layer, semiconductor component initiated by a biassing voltage as the temp. sensor. This sensor can be exchanged to avoid fresh calibrations of the null point and the scale factor. It is esp. useful in chemical thermometers since a separate sensor can be used for each patient. The temp. is derived from the differential inner resistance of the semiconductor component. An a.c. can be applied to the latter and the resulting voltage drop evaluated to find the temp. The semiconductor component can be a diode. The working point of the component can be adjusted so that it operates in a quasi-linear characteristic section. The component can be embedded in a glass, plastic or ceramic sleeve and provided with a plug-in arrangement.

Title: Dust control in surface blasting, esp. quarrying - by placing hygroscopic salt in borehole over explosive charge
Inventor: LEWER HANS
IPC: F42D1/24
Filed: 1979-09-15
Abstract: Dust control involves the use of a charge of finely- divided hygroscopic salts, pref CaC12 and/or MgC12.

Patent DE-3017715-A1 (DE)
Title: Warp knitter control - has comparator and gate circuits to control warp beam advance
Inventor: SAKAMOTO MASAAKI
IPC: D04B27/22
Filed: 1980-05-09
Abstract: The control mechanism for the warp feed to a warp knitter, where there are impulses to register the fabric worked for impulses to move the warp beam accordingly, incorporates a gate to pass impulses to an impulse counter. The other impulse counter has a number of decade counters where the first counter is linked to a comparator circuit, while the others are linked to a cut-off for the warp knitter through an OR circuit. The mechanism to advance the warp beam, for warp feed, is controlled by two AND elements where the one output of a flip-flop is connected to both AND elements and the one and zero outputs of another flip-flop are connected to the two AND elements. A second comparator circuit is connected to the output of an intermediate counter, fed by a separate impulse generator, to interrupt the flow of impulses to the intermediate counter and to return the first flip-flop when the count is agreed within a preset tolerance. The system allows a fault to be assessed, to determine whether fault correction is required, or whether the warp knitter should be stopped.
Patent DE-3020888-A1 (DE)
Title: Workpiece holder jig for hardening plant - where bore of spider hubs has axial grooves through which quenching liq. can flow to minimise thermal shock
Inventor: KLEFISCH RUDOLF
IPC: C21D1/63
Filed: 1980-06-02
Abstract: The jig consists of an axial rod employed to hold a vertical row of carrier arms or spiders. Each spider consists of a central hub with arms arranged like the points of a star. In the bore of the hub is a circular row of axial grooves; and the base of each groove is semicircular in shape. The axial rod is pref. provided with at least one axial rib with a semicircular tip entering a groove in the bore of the spider hub. The rib prevents the spiders from rotating on the axial rod. When the jig is immersed in a quenching liq., the latter can flow through the grooves so all parts of the jig are cooled uniformly and thermal stresses are reduced. The result is that the working life of the jig is increased, as the hubs are less inclined to fracture.

Title: Brake control for railway traffic - has oscillation receivers near mechanical retarders transmitting signal for short duration brake release on prohibited noise direction
Inventor: SCHMALL JUERGEN DIPL ING
IPC: B61K7/02
Filed: 1980-07-14
Abstract: The brake control is applicable both to the rails and to the rolling stock. It contains retarding mechanisms which, in effective position, reduce the vehicle speed by mechanical braking, at least partly. Near the retarding mechanisms (B) are mounted oscillation receivers (SA) which transmit a signal for short duration reduction of the braking force of the retarding mechanisms, on appearance of unpermissible braking noise in the effective region of the retarders. Acoustic receivers are pref. used for the signal transmission and they may be in acoustic connection with the retarding mechanism. If the receivers are in the form of acoustic transducers, they may be fitted separately from the retarders, but may have a receiver characteristic with directioning towards the retarders. To the receivers may be allocated filters (F), tuned to the frequencies of the unacceptable brake noises.
