Patent DE-3827830-A1 (DE)
Title: Kinetic energy projectile
Inventor: REUSCH RUDOLF
IPC: F42B10/12
Filed: 1988-08-02
Abstract: A kinetic energy projectile comprises a sub-calibre penetrator and a discarding sabot which surrounds it concentrically. In order to manufacture the projectile more cost-effectively, the discarding sabot (11) which concentrically surrounds the penetrator (10) is constructed integrally. The penetrator (10) is mounted in the discarding sabot (11) such that it can be displaced axially. Thrust is applied to both from the rear, by means of clamping jaw segments (26). After the end of the thrust process, the discarding sabot (11) and the clamping jaw segments (26), which are forced outwards in this case, are stripped off to the rear. The fin surfaces (15) which are necessary for stabilisation are mounted at the front in the discarding sabot (11) and are taken with the said discarding sabot (11) when it leaves the penetrator (10). In contrast to conventional discarding sabots consisting of several parts, disadvantageous influences on the trajectory (flight path) of the penetrator are thus at the same time avoided during the process of releasing the discarding sabot from the penetrator. The risk of fracture from threaded grooves has been limited, since reductions in cross-section are located only in the rear region. The manufacture of this projectile is considerably easier and cheaper. <IMAGE>

Patent DE-3902343-A1 (DE)
Inventor: BECK ERNST GEORG DIPL BIOL
IPC: H04R1/22
Filed: 1989-01-27
Abstract: A loudspeaker enclosure (1) operates in accordance with the acoustical band-pass principle and exhibits an external housing (2) in which an internal baffle board is provided with preferably two loudspeaker chassis attached thereto. The two loudspeakers (4, 4a) enclose a coupling volume between themselves and are located in chambers (5, 5a) which are sealed against one another. These chambers are connected to the external area via reflex openings (7, 7a). The loudspeaker chassis are acoustically connected in series and operate in phase acoustically. Having the same frequency response compared with a reference loudspeaker enclosure with one loudspeaker, this results in an approximate halving of the housing volume. In addition, distortions of the individual loudspeaker chassis are largely compensated for. The load-carrying capability of the loudspeaker enclosure is increased in accordance with the number of loudspeaker chassis, the use of two loudspeaker chassis resulting in approximately a doubling of the load-carrying capability. More than two loudspeaker chassis can also be arranged acoustically in series and operating in phase. <IMAGE>

Title: Lock cylinder with device preventing removal
Inventor: LAURENZ LOTHAR
IPC: E05B9/08
Filed: 1989-02-15
Abstract: The invention relates to a lock cylinder (1) with a device preventing removal which is arranged on the cylinder housing and which has a retention surface (18) projecting beyond the cylinder housing and formed by a bolt (8) which is spring-loaded in the outward direction, the said surface (18) being assigned an abutment bevel (19) coming into action in the push-in fitting of the lock cylinder (1). In order to facilitate the incorporation of the lock cylinder and to achieve high retention forces, the invention proposes that the cylinder housing of the locking cylinder (1), designed as a profile cylinder, has a transverse channel (5) running through it at the level of the flange area (3). At the end of the channel (5) there is an inwardly directed edge (20), and a rotationally secured telescopic bolt (8) consisting of two resiliently spread bolt parts (9, 10) is mounted in the channel (5), the two end sections of the said bolt (8) forming the abutment bevels (19) adjoining the retention surfaces (18). <IMAGE>
Patent DE-3908850-A1 (DE)
Title: Dental instrument
Inventor: AXELSSON PER AXEL TORBJOERN
IPC: A61C17/18
Filed: 1989-03-17
Abstract: Dental instrument for cleaning and smoothing the surfaces of dental roots, comprising a conical or flattened working member from which one or more counter-sunk grooves are cut out. Opposite lateral surfaces of these grooves form a sharp, essentially right-angled cutting edge, part of the working member being arranged on each side of the groove. Once the deposits on the tooth have been removed and the dental surface has been smoothed, these regions form pressure-relieving surfaces which rest against the dental surface and prevent the cutting edge from coming into contact with the dental material and from removing further, undamaged dental material in an undesirable manner.
Patent DE-3909631-A1 (DE)
Title: Device for sucking off coating material, such as, for example, lacquers, out of the applicator nip between two applicator rollers
Inventor: FRICK ANDREAS
IPC: H05K3/00
Filed: 1989-03-23
Abstract: A device for sucking off coating material, such as, for example, lacquers, out of the applicator nip between two applicator rollers provides two suction pipes which are arranged horizontally displaceably and which are connected on the outlet side to an appliance for generating a negative pressure and to an appliance for intercepting the sucked-off coating material. Particularly when a photosensitive resist is being applied to the plate-shaped basic material during the production of printed circuit boards, accumulations of the coating material in the edge region of the plates running through can be avoided, without the applicator rollers being subjected to mechanical stress. By means of the negative-pressure appliance, the quantity of coating material occurring when the plates to be coated run through can be sucked off continuously and supplied again via the intercepting trough to the coating material to be processed.
Patent DE-3911496-A1 (DE)
Title: Actuating device for an inlet and exhaust valve of an internal combustion engine
Inventor: MUELLER ANDREAS
IPC: F01L9/20
Filed: 1989-04-08
Abstract: Holding devices and spring elements are provided in the two dead centre positions of an internal combustion engine valve. Under the influence of the preloaded spring elements, phase-shifted release or closure of the holding devices causes the valve to perform an oscillating movement. According to the invention, the position of the holding device defining the open position of the valve can be adjusted. Likewise the preloading force of the associated spring element can be adjusted. This allows the maximum valve lift, the valve closing speed and the opening period to be influenced. The holding devices are preferably designed as solenoids.

If the pressure of the infused liq. rises unduly, it shuts the valve against the force of magnetic repulsion. ADVANTAGE - Offers a reliable protection against undue pressure rises and needs no extraneous control or energy.
