Title: Transportation device for unbelted ammunition
Inventor: KOINE RICHARD
IPC: F41A9/16
Filed: 1987-11-13
Abstract: Known transportation devices for transporting unbelted ammunition from an elevation-independent hand-over point into an elevation-dependent ramming position in the region of the breech of an automatic weapon with a barrel require such a large amount of space that they can be integrated only with difficulty, especially in relatively small gun turrets. According to the invention, a transportation device for unbelted ammunition is proposed which is distinguished by a construction which is simple in terms of the drive and mechanically and which can even be installed in small tank turrets or light armoured vehicles, because of its small space requirement. The transportation device (5) according to the invention, which is advantageously designed as a jointed drive, consists of a compensating element (15) having a cartridge chamber (16), of a crank (22), a coupling element (22) and a rocker arm (34). In order to transport a cartridge into its ramming position such that the elevation is compensated for, the compensating element (15) is pivoted about the trunnion axis (14) by displacing the crank (22), which is hinged on the compensating element (15), in a guide slot (26) in the coupling element (28), in synchronism with the breech movement. As a result of the simple, advantageous construction of the transportation device (5) according to the invention, its width is essentially still limited to the size of the cartridge diameter, it being possible additionally to move over a large elevation range of the weapon with a barrel. <IMAGE>

Title: Device for squeezing out wet cloths
Inventor: RITTER GEORG DIPL ING
IPC: A47L13/59
Filed: 1988-02-06
Abstract: With this innovation, wet cleaning cloths, for example, are effortlessly and safely wrung out - to be more precise squeezed out - without them having to be touched or held by the scrubbing brush. The squeezing channel 8', suspended freely above the upper edge 11 of the bucket, with the loosely inserted cleaning cloth is pushed downwards with little effort a few cm and thus reduces its width 8. During this process, a considerable pressure is exerted on the cleaning cloth as a result of lever actions of the device. The device according to the invention is also extremely well suited, however, to the drying of wet washing, wet chamois leather, wet paper, to the squeezing out of fruit and the like, as it guarantees an excellent drying result while requiring little effort and being convenient to use. <IMAGE>

Title: Method of applying a colour decoration in the form of unevenly distributed flecks of different colour intensity (variegation) onto and into the facing layer of a two-layered panel
Inventor: HENKE WILHELM
IPC: B28B7/38
Filed: 1988-04-23
Abstract: The invention relates to a method according to the precharacterising clause of Claim 1. The object of the invention is to provide a method of applying a colour decoration in the form of unevenly distributed flecks of different colour intensity (variegation) onto and into the facing layer of a two-layered panel, after which the colour decoration is fully retained even if there is abrasion on the visible surface of the facing layer. This object is achieved according to the invention by the colour or a colour medium being applied in a way corresponding to the decoration to the bottom ply before introducing the facing material, by subsequently pouring the facing material onto a plate, which has unevenly distributed slot-shaped clearances of various shapes and is surrounded by a frame, before introduction into the moulding box, and by the plate being shaken during the pouring-on operation transversely to the direction of pouring in such a way that the facing material is distributed unevenly on the bottom ply.

Patent DE-3815492-A1 (DE)
Title: Connecting system for a cylindrical, metallic pipe
Inventor: SCHWALM DIETER
IPC: F16L13/14
Filed: 1988-05-06
Abstract: The connecting system serves for the pressure-tight connection of a cylindrical, metallic pipe (1 and 2) to a connecting sleeve (3) into which the respective pipe end can be pushed in a positively locking manner. The connection effected with the aid of a tubular, metallic clamping ring (10 and 11, respectively), the internal diameter of which is smaller than the initial external diameter of the connecting sleeve (3), the clamping ring exhibiting an inner, conical inlet portion (12), and it being possible to press it onto the connecting sleeve (3), as far as the connecting position, by axial force. By virtue of the radial forces which come into effect in this case, the connecting sleeve (3) and pipe end are deformed in the contact region. In order considerably to increase the connection resistance against torsion as well as axially acting forces, the connecting sleeve (3) contains a plurality of wall bores (8 and 9) which follow one after another at the same spacing in the circumferential direction. As a result of the relatively low degree of deformation in the region of each individual wall bore (8 and 9), convex bulges are formed here, these causing additional mechanical locking between pipe (1 and 2) and connecting sleeve (3). <IMAGE>

Title: Apparatus for separating irregular pieces using vibration conveyors
Inventor: SCZIMAROWSKI KLAUS PROF DIPL I
IPC: B65G47/14
Filed: 1989-01-04
Abstract: Owing to the different and irregular shapes of the pieces, for example of scrap items, belt feeds and vibration grooves have not proved to be expedient. The items become entangled and stay together above and next to one another. However, to record measured values for subsequent sorting, separation - a line of pieces lying one after the other - is essential. This object is achieved by apparatuses consisting of sliding track segments which are combined to form sequences of sliding tracks of different shapes and inclinations and which can be controlled by variable oscillation parameters so that a specific sequence of rectification and accumulation stages leads to a line of pieces lying one after the other. The apparatuses are used as a preliminary stage for specific sorting tasks, e.g. for the alloy sorting of scrap items.
Patent DE-3904346-A1 (DE)
Title: Device for disinfecting liquids and gases by means of ultraviolet radiation using the counter-current principle
Inventor: UEBERALL PETER
IPC: A61L9/20
Filed: 1989-02-14
Abstract: When designing UV disinfecting units it is not always easy to permit the entire volume of the disinfecting chambers to be completely filled by the streamlines of the medium flowing through them, so that the throughput and the container volume are an exact measure for calculating the irradiation time. As technically adequate approximation to said condition, the invention proposes flow through the UV disinfecting chamber by the counter-current method such that inflow and outflow of the medium are located at the same side of the chamber, the medium is axially sprayed in through a nozzle and passes as a jet through the medium present in the chamber until it impinges on the opposite side of the container wall, distributes on the sides and returns, in a swirled state and so as to fill the cross-section not reached by the jet, to the outflow on the inflow side. This guidance of the stream permits, for example, use of small compact UV disinfecting units whose shape and size can be adapted to suit the commercially available domestic water filters and can be connected downstream from these.

Patent DE-3924872-A1 (DE)
Inventor: BAYER FRANZ
IPC: E06B3/673
Filed: 1989-07-27
Abstract: To provide perforations on the webs (4) of spacer frames (1) formed from hollow sections (2), the said webs facing the pane interspace (5) of an insulated glazing unit, the region of perforation is first of all deep drawn in the direction of the inside of the section (2) and a hole is then punched in the deepest point of the deformation (7a) thereby obtained. This deep-drawn region is then rolled in such a way that the depth of this deep drawing is somewhat reduced and the perforation (6a) is thereby pressed to in a dust-tight manner. This can be achieved in a simple manner with a roll (9) having a circumferential groove (10), giving rise overall to a spacer frame (1) which has pressed-to openings (6) at the deepest - or highest - point of knob-shaped depressions (7) on its webs (4) facing the pane interspace (5), with the result that pulverised or crushed desiccant dust is prevented from falling out not only by the reduction in the cross-section of the openings (6) when pressed to, but also by their raised position relative to the upper horizontal web (4) of the hollow section (2).
