Title: Gas-blast circuit breaker
Inventor: KIRCHESCH PETER DIPL PHYS DR
IPC: H01H33/98
Filed: 1988-10-03
Abstract: The gas-blast circuit breaker contains a stationary (2) switching element and a moving (1) switching element, each of which has a rated-current contact (4, 5) and a consumable contact (6, 7). Provided on the moving switching element (1) are a pressure space (10) (which stores an extinguishing gas which compresses the switching arc during switching off and whose volume is independent of the switching stroke) and an insulating nozzle (8), whose nozzle constriction (9) is sealed in the high-current phase of the switching arc (24) during switching off, from (by) the consumable contact (7) of the stationary switching element (2). In this switch, the insulating nozzle (8) is intended to be subjected to comparatively low thermal loads in order to increase the extinguishing gas pressure in the pressure space (10). This is achieved by rotation of the switching arc (24) in the high-current phase in that, specifically, on the one hand, the consumable contact (6) of the moving switching element (1) is mounted in an electrically insulated manner on a contact support (15) of the moving switching element (1) and, on the other hand, is electrically conductively connected, via a coil (19) which surrounds it coaxially, to a current connection of the moving switching element (1). <IMAGE>

Title: Optical transmission device
Inventor: WEDDING BERTHOLD DR RER NAT
IPC: H04B10/032
Filed: 1988-12-24
Abstract: Devices exist for transmitting light for optical communications which contain a single-mode semiconductor laser (1), an arrangement for modulating the light which is to be transmitted and an optical transmission medium, e.g. optical waveguides. Only one of the two front sides (11, 12) of the semiconductor laser (1) is used to generate transmission light. According to the invention, light beams (L1, L2) from both front surfaces (11, 12) are combined in a light-combining element - e.g. in the case of optical waveguides (41, 42) in an optical coupler (3). Depending on how the light to be transmitted from one output (33) of the optical coupler (3) is intended to be modulated, the arrangement for modulation can be implemented in different ways, for example, by designing the optical coupler (3) simultaneously as an arrangement for modulation. <IMAGE>

Title: Method on a multi-colour printing machine operating by the halftone process to achieve a preselected printing result
Inventor: BRUNNER FELIX
IPC: B41F33/00
Filed: 1989-02-14
Abstract: The invention relates to a method on a multi-colour printing machine operating by the halftone process to achieve a preselected printing result on a printing carrier. Measurement values in the form of full-tone densities and/or halftone densities are gained from measurement zones printed on the printing carrier and deviations of momentary printing results from the preselected printing result are determined from the measurment values. In order to adapt the momentary printing result to the preselected printing result as quickly as possible, if required, the supply of the printing inks at least to selected inking zones of the printing carrier is firstly changed for a limited period to a greater extent than corresponds to the deviations determined and only after this period is set to correspond to the deviations.

Title: Tool case, in particular for motor vehicles
Inventor: SCHAFSTEIN FRANK
IPC: B25G1/04
Filed: 1989-02-15
Abstract: In a tool case, use is made of two case shells which are joined together by a film hinge and have, on their inner face, depressions for holding the tools and on their shell edge remote from the hinge a moulded-on handle. In order to obtain a tool case which is as stable as possible and provides a compact arrangement of the tools, it is proposed to give the case shells a semicircular outline, the semicircle diagonal forming the narrow side of the case with the hinge and serving as standing face of the case. The segments of a circle which are located opposite the hinge form the two longitudinal halves of a handle of the tool case.
Patent DE-3905016-A1 (DE)
Title: Drill for making drill holes in masonry
Inventor: FISCHER ARTUR PROF DR
IPC: B23B51/10
Filed: 1989-02-18
Abstract: To make drill holes in masonry, rock drills are known which, when used in gas concrete, produce drill holes whose diameter often clearly exceeds the desired nominal diameter. The inserted wall plugs then often do not have adequate retaining values. A drill is proposed, the front shank part of which has a reduced diameter. Moreover, additional cutting edges are formed at the transition from the reduced drill-shank diameter to the larger drill-shank diameter. A reduced drill hole can thereby be made in masonry in one operation, a drill hole of nominal diameter being made in a fastening object.

Patent DE-3907429-A1 (DE)
Title: Ioniser for the effective generation of ozone
Inventor: KOSSACK CHRISTIAN
IPC: C01B13/11
Filed: 1989-03-08
Abstract: The invention relates to a process for the effective generation of ozone for use in fields in which its use was hitherto not possible, in particular uneconomical, because of the size of conventional apparatus and the costs of the production process. The invention uses the already customary technique of ionisation as starting point. The novelty is, on the one hand, that a semiconductor or nonconductor, which is capable of forming micropores or already possesses such pores without pretreatment, is used as a coating of the part of the apparatus functioning as ioniser or else is arranged separately from the ioniser in the form of a film or plate. By means of the coating used serving as current limiter and silent discharges "breaking through" it because of the presence of micropores, the striking (ignition) of an undesired and damaging electric arc is prevented. As a result, the spacing of the conducting plates can be reduced and a yield of ozone generated increasing exponentially therewith can be achieved. On the other hand, it is novel that the shape of the ioniser can be made like that of a ribbon (flat strip) cable.
Patent DE-3920756-A1 (DE)
Title: Tightened threaded plastic component - has cut=out on thread to contain pivoting strip whose threads align with others when tightened and which lock to prevent loosening
Inventor: SCHEWE HERMANN
IPC: F16B39/32
Filed: 1989-06-24
Abstract: A threaded plastic component with a screwed piece has a recess in part of its fixed thread, where a threaded area can move between two side positions and can pivot about an axis which is approx.  radial to the centre line of the threaded part; it pivots from one position taken up when it is screwed up tightly and in which the crests of the thread are projections of  the adjacent crests of the thread on the fixed part. In its other position, taken when unscrewed, its thread crests lie at an acute angle to the adjacent crests, so that the thread of the screwed piece is locked by that of the moving part; in this assembly the moving part is elastic and can be moved from its starting position into either direction of pivoting. The screwed piece is preferably also plastic material. ADVANTAGE - The threaded assembly is a safe one and will not become loose with time i.e. unlike screwed plastic components hitherto it remains tightly screwed.
