Title: Breech for firearms, especially for drop-barrel weapons
Inventor: REPA OTTO
IPC: F41A3/58
Filed: 1984-07-17
Abstract: When the breech is in the closed and locked state, the barrel of a drop-barrel weapon is pressed by means of a locking surface of the barrel lug against a corresponding locking surface of the stationary breech part. In order to obtain a defined and precisely fitting orientation of the barrel with respect to the stationary breech part, the locking surface is formed by an intermediate piece which is arranged on the barrel lug and/or on the stationary breech part such that it can be replaced. For accurately fitting assembly of the breech parts in mass production, a plurality of intermediate pieces of different thickness are inserted successively during assembly until the defined orientation of the barrel with respect to the stationary breech part is achieved. In order to compensate for manufacturing tolerances, one or more shims of the same or different thickness can also be used, which can be inserted between the respective breech part and the intermediate piece.

Patent DE-3438160-A1 (DE)
Title: Centrifugal drive
Inventor: SOEDER RUDOLF
IPC: F16H33/00
Filed: 1984-10-18
Abstract: To eliminate the speed limitation for space missiles, brought about by the use of jet-propulsion drives, centrifugal forces are used as driving forces. The centrifugal forces are generated in a running ring as a result of the oppositely directed movement of two running elements and are controlled by its simultaneous rotation in a respective main direction. A linear effect of the driving forces is achieved by connecting a plurality of running rings, at least two, or by combining the cycles of movement of one running ring, to form a track loop. The efficiency is improved by a multi-stage design of the drives and the use of connected running rings or track loops in place of single running elements.

Title: Safety belt fastener with holder
Inventor: GRASSMUCK JUERGEN DIPL ING
IPC: B60R22/22
Filed: 1985-05-22
Abstract: In a fastener for safety belts, in particular in motor vehicles, having a holder for attaching the fastener to a vehicle-mounted part, the fastener having a channel-type frame for insertion of a lock tongue with a lock plate, and the mainly rigid, bar-shaped holder being connected pivotably to the fastener, the problem consists in the fact that the forces acting in the event of an accident are to be introduced solely into the lock plate. To solve this problem, it is proposed that the holder (12) engages through the lock plate (10) in a cutout (13) with a bent portion (14) constructed at its front end region, and that a bolt (16), which fixes the holder (12) and the lock plate (10) relative to each other and has at least one contact surface (18), is arranged to limit the pivoting path. <IMAGE>

Title: Apparatus for removal of viscous liquids stored in medium to large containers
Inventor: ZIRNBAUER JOSEF
IPC: B67D7/60
Filed: 1985-07-11
Abstract: To make it much easier to transfer glue from primarily commercial 30 or 35 kg drums or containers into smaller vessels for further processing in joiners' workshops and similar enterprises, a device (1) for removing viscous liquids, especially glue, stored in the containers is mounted on the screw closure or lid of the container. In this process, a submersible tube (2) is lowered into the container via the container opening. A conveying worm situated in the submersible tube (2) is driven by means of a hand crank (27, 28) and conveys a desired quantity of glue through an outlet pipe (6). The outlet pipe (6), which is initially bent upwards, prevents any unwanted backflow of the glue. A sealing cap (12) on the outflow opening (11) of the outflow pipe (6) prevents the ingress of air and therefore the drying-out of the glue. A reduced version of the device (1) can also be used for commercial 10 kg containers. <IMAGE>
Patent DE-3525777-A1 (DE)
Title: Process for the preparation of a binder for offset printing inks, and a binder prepared by the process
Inventor: KUEPPERS GERHARD DIPL ING
IPC: C09D11/02
Filed: 1985-07-19
Abstract: The binder used in printing inks for offset printing is a linseed oil varnish. The printing ink consistency necessary for the printing operation is established through the viscosity of the binder. However, the decals printed using this binder for ceramic colour printing have crucial disadvantages since the polymerisation of the binder continues during storage of the decals, so that the decals become brittle and can only be applied to the ceramic articles with great difficulty. Further disadvantages occur on firing of the decal.   These disadvantages are avoided according to the invention by mixing the oil in unpolymerized form with a polyacrylic resin or a polymethacrylic resin at temperatures above 150 DEG C until a binder solution is formed. The requisite consistency of the printing ink is established through the viscosity and amount of acrylate resin. The unpolymerised oil has good firing properties. Embrittlement of the decal does not occur even on extended storage.

Title: Circuit arrangement for switching over winding taps, in a contact-free manner, in the case of transformers
Inventor: LASCH WERNER
IPC: H02P13/06
Filed: 1985-09-26
Abstract: The invention can be used in the case of processes for voltage setting and voltage regulation. The object of the invention is to create a circuit arrangement by means of which the interruption-free changeover from one winding tap to another is possible without the interposition of a lower voltage, irrespective of the switching direction, under conditions where no short-circuit occurs between the winding taps and the phase angle between the current and voltage still has no effect. A number of windings are arranged on a common iron core, which number corresponds to the number of winding taps, each winding being connected in series with in each case one winding tap of the transformer and a semiconductor switch. The winding sense of the windings which are arranged on the common iron core is in each case in the opposite direction for adjacent windings. The semiconductor switches are driven such that one or two adjacent semiconductor switches are always switched on.

Patent DE-3614366-A1 (DE)
Title: Arrangement for avoiding undesired solder links on printed circuits
Inventor: AMANNN GUENTER JOHANN
IPC: H05K3/34
Filed: 1986-04-28
Abstract: The invention relates to an arrangement for avoiding undesired solder links during soldering of electrical components on to printed circuit boards by means of soldering machines. The risk of short circuits being formed by solder during wave soldering, with the solder bridging conductors or solder points inadvertently, increases more and more as a result of the miniaturisation in electronics. Particularly at risk are points or regions on the printed circuit board which are located in the transition region from good to poor main contact of the solder wave with the printed circuit board. In order to avoid such links being formed, the invention provides, in addition to the actual conductor pattern, solder lands (1) without any electrical function, at a distance from the conductors in the direction in which the soldering takes place, behind the solder lands (2) or conductor tracks which are followed by a region which cannot be soldered, either on the printed circuit board (3) or on the solder receptacle.
