Patent DE-3271488-D1 (DE)
Title: Electrical switchgear
Inventor: PARRY JOHN
IPC: H01H33/18
Filed: 1982-01-26
Granted: 1986-07-10
Abstract: A first contact 10 has an end portion 16 which engages a second contact 17, 18 in a contacts closed position of the switchgear and which moves transversely across a pole face of a field coil 23 and inwardly of an axis 24 of the latter during movement of the contacts to an open position. The field coil 23 is electrically connected in series with an arcing electrode 22, and to which the second contact 17,18 is also connected. Upon movement of the contacts from their closed position to their open position, an arc is drawn between the end portion 16 of the first contact and a portion 18 of the second contact. Further movement of the contacts towards their open position causes the arc to transfer its root from the second contact portion 18 to the arcing electrode 22 so that an arcing current then flows through the field coil 23 to generate a magnetic field which causes the arc to rotate and become extinguished. Extinction of the arc is assisted by an electrically insulating fluid surrounding the switchgear. A principal arcing zone is defined by rotation of the arc, and the arc is disposed in this zone when it transfers its root from the second contact to the arcing electrode 22 so that it can rotate immediately under the influence of the magnetic field.

IPC: G02B21/14
Filed: 1983-07-01
Granted: 1986-01-09
Abstract: A transmitted-light illuminating device (FIG. 1) for microscopes consists of a condenser (1), an iris-aperture diaphragm (2) and a turret (3). The turret permits interchangeable mounting of auxiliary lenses (4) or diaphragms (5) by means of which large-object fields can be illuminated, if desired; alternatively, the microscope can be used in phase contrast. Condenser, diaphragm and turret are combined into a unit in which the turret is functionally coupled to the iris diaphragm. For this purpose, the index shaft of the turret (3) is eccentrically mounted to the actuating ring (9) of the diaphragm (2), the ring is configurated for detent engagement to retain the newly indexed turret station in axial register with the optical axis of the condenser. Thus, rotation of the turret first drives the actuating ring (9) against its diaphragm stop to thereby open the diaphragm before there is any indexing movement of the turret, from one to its next indexed position.

Abstract: This electronic cash register system includes a means for storing a master file having reference data for the entirety of a set of items of goods, a transfer means, and a plurality of electronic cash registers. Each of the registers includes a means for storing a sub file having reference data for a subset of the set of items of goods, and a means for consulting the sub file for reference data for a particular item of goods which is to be dealt with and for, if and only if the sub file does not hold the reference data, obtaining the reference data from the master file via the transfer means. The system further includes a means for, according to data of goods dealt with, determining a subset of the set of items of goods the members of which are often dealt with, and a means for updating the sub files kept at the electronic cash registers according to the thus determined subset. Thereby the dealing with items of goods can mostly be accomplished locally. Accordingly, this sytem can increase the speed of transaction processing, and the capacity of each local sub file storage means can be much smaller than the capacity of the master file storing means. If the master file has become inoperative, effective transaction processing can still be provided for most transactions. And, since the sub files are updated by the updating means, the data therein may be kept current.

Date Apr. 23, 1987.A driving method is provided for arrays of liquid crystal elements having a linear response to an applied electric field, and specifically ferroelectric liquid crystals capable of two surface-stabilized states. The presented schemes write simultaneously both states in one scan of the array, recognizing both the threshold as a critical voltage-time area and keeping this integrated averaged area equal to zero for symmetrically responding pixels. The voltage pulse trains are optimized to intrinsically assure stabilizing rms torques without applying separate holding voltages. Improvements in contrast and frame writing speed are achieved by optimizing driving parameters and scan procedures, such as scanning in loops, in combination with impedance switching.
