Abstract: A firing circuit for two antiparallel-connected power thyristors. Each of the power thyristors has a gate terminal; the gate terminals being connected by a series combination of auxiliary thyristors. Each of the auxiliary thyristors is of the type which can withstand firing resulting from excessive anode cathode potential; the sum total of the anode cathode potentials of the series-connected auxiliary thyristors being less than the anode-cathode breakdown voltages of the power thyristors. This, while a power thyristor is in a nonconductive state, an anode-cathode voltage is impressed thereacross in the forward conduction direction. At an anode-cathode voltage which is less than the breakdown voltage of the power thyristor, the auxiliary thyristors are fired so as to form a conductive path which includes the cathode-gate path of the other power thyristor, the auxiliary thyristors, and the gate-cathode path of the protected thyristor. Normal firing of the power thyristor is achieved via the auxiliary thyristors, which may be fired by light pulses or current pulses. Thus, the auxiliary thyristors perform protective and normal firing operations.

Abstract: A magnetic article surveillance system marker is adapted, when armed, to resonate at preselected frequencies provided by an incident magnetic field applied within an interrogation zone. The marker is a pluraliry of elongated ductile strips of magnetostrictive ferromagnetic material each of the strips being disposed adjacent to a ferromagnetic element which, upon being magnetized, magnetically biases the strips and arms them to resonate at the preselected frequencies. A substantial change in effective magnetic permeability of the marker at the preselected frequencies provides the marker with signal identity.

Abstract: The lift landing door frame arrangement contains horizontally adjustable lateral caulking or sealing elements arranged at uprights of the door frame and a vertically adjustable top caulking or sealing element associated with the topside of the door frame. To avoid retouching due to the caulking elements at the time of placement of the lift landing door frame arrangement and to avoid the formation of gaps in the door frame after placement, each lateral caulking element comprises a rectangular sheet metal panel of a length which exceeds the height of the door frame. Each lateral caulking element engages with and is fixed to the interior of the related upright. Each lateral caulking element is also guided for simultaneous vertical and horizontal adjustment at a guide plate carried by the related upright. The vertically adjustable top caulking element is constituted by a U-shaped sheet metal strap which is disposed astride the front parts of the door frame and is laterally guided thereat. This lift landing door frame arrangement is particularly suitable in cases in which the lift or elevator shaft does not include lateral masonry returns at the landing openings.

Abstract: During operation of a rolling mill the roll gap and roll shape change, because of the influence of heat, bending of the working rolls or the roll mounting, wear and the like, and must be compensated and/or balanced to make a planar product, particularly a planar rolled sheet or strip. To compensate for these undesirable disadvantageous influences on the operation of the rolling mill frequent axial sliding of the rolls with respect to each other and/or positioning of the working rolls transverse to the plane of the rolled material is required. These undesirable influences are prevented in a particularly simple way and/or are compensated when the contours of the rolls in the initial state and/or unloaded state of the rolling mill are such that the sum of the roll body diameters at each relative axial position of the rolls varies axially from a constant value.
