Patent DE-3824572-A1 (DE)
Title: Universal machine
Inventor: KREHER PETER-JUERGEN DR ING
IPC: B23P19/04
Filed: 1988-07-19
Abstract: The invention relates to a universal machine which can contain both machining and assembling units. In contrast to a conventional machine tool in which the work-carrying unit sits, for example, in a movable manner on a longitudinal guide on which the tool-carrying units are possibly also arranged in a fixed or movable manner, the present machine has two parallel guides lying in a common horizontal plane, the tool-carrying or manipulating units being located mainly on the one guide and the work-carrying units being located on the other guide. The construction units mounted on these guides in turn have further guides, by means of which tools, manipulating devices or workpieces can also be moved in the other coordinate directions. In this arrangement, the guides in all coordinate directions are to have the same form and dimensions in order to enable a subassembly provided with guides to be put onto any available guide, no matter which coordinate direction. This universal machine can thereby be completely dismantled and reconstructed after the respective job order, a limitation to a maximum of five degrees of freedom on the tool side and one degree of freedom on the workpiece side, compared with the requisite expenditure, offering the optimum combination.

Title: Fuel injection system for internal combustion engines
Inventor: KAMPICHLER GUENTER DIPL ING
IPC: F02M45/04
Filed: 1988-10-04
Abstract: The invention relates to a fuel injection system for internal combustion engines with at least one injection pump and assigned injection nozzle, which are line-connected by way of a pressure line. The object of the invention is to be able, as necessary, to configure a system without preinjection as a system with preinjection or to convert it into one. This object is achieved in that a self-contained preinjection unit, which comprises a preinjection piston and a pressure step piston is insertable into the pressure line, both pistons at one end being exposed to the fuel coming from the injection pump in an upstream pressure line section, whilst the preinjection piston with its other end is movable over a predetermined stroke in a working chamber, which is constantly open to the downstream pressure line section leading to the injection nozzle, so that the quantity of fuel from the downstream pressure line section intended for preinjection is delivered to the injection nozzle from the said working chamber by the preinjection piston. <IMAGE>

Title: Search method for a data memory, and device to execute the method
Inventor: GEBELEIN UDO DIPL ING
IPC: G06F17/30
Filed: 1989-03-16
Abstract: In an n-dimensional (n = 1, 2, 3, 4, ...) co-ordinate system, a finite management space, a search space within the management space and search objects are specified. The search objects which intersect the search space are to be identified. In the Cartesian co-ordinate system, the search space is defined by an orthogonal grid, so that for each corner of the search space there is a corresponding grid point. The search objects are described by orthogonal rectangles or cuboids, which may degenerate to points. Using the grid, the management space is divided in each dimension into maximum strips, so that no corner is within a strip, but every strip is delimited by corners. The search space is processed and stored in such a way that the time cost for an overlapping test, if data processing systems with sufficient word width are used, is independent of the complexity of the search space. For this purpose, for each search object, a test is done of whether at least one intersection space of n strips, which intersect the search object, and are all assigned to different dimensions, is within the search space.

Title: Tube weapon having a liquid propellant as the propulsion means
Inventor: POLITZER ANTON
IPC: F41A1/04
Filed: 1989-04-07
Abstract: In the case of a tube weapon, channels (26) in a piston (22) open into a combustion space for burning a liquid fuel.

Title: Hydrocephalus relief valve - has excessive cerebrospinal fluid passed via valve into pressure cylinder containing spring-loaded piston
Inventor: SPIEGELBERG ANDREAS DR
IPC: A61M27/00
Filed: 1990-08-18
Abstract: The cerebrospinal fluid is passed under cerebral pressure by a 2/2 way valve (5) into a pressure cylinder (4) when this pressure is greater than that formed by the cylinder piston (2)  under spring-loading.  This occurs in a first position of the valve, and in a second valve position the fluid flows out of the cylinder under the pressure of the spring. A time generator (7) switches the valve (5) into action on a cyclic basis, and an excess pressure valve (6) is connected in parallel to the 2/2 way valve, permitting fluid above its operating pressure to flow away.  A check valve (8) prevents back flow.  In an alternative version, the spring-loaded piston can be replaced by a bellows which is also spring (1)-loaded. USE - To conduct away excessive cerebrospinal fluid.
Patent DE-4027610-A1 (DE)
Inventor: FRIES JAN RICHARD DE
IPC: F15B13/04
Filed: 1990-08-31
Abstract: The invention relates to a valve having a valve housing (1) in which a slide holder (6) is constructed. The latter contains a valve slide (7), which can move to and fro between indexing positions and is able to connect the valve channels (11), constructed in the valve housing (1), to one another individually in fluid terms. To this end, it has window-like laterally running perforations through which the fluid can flow when transferring between two valve channels (10). With a low flow resistance, this valve design permits the implementation of large flow cross-sections.

Title: Screen construction - utilising knitted fabric with periodical slits for stay supports and to close gap between sections
Inventor: BANNING H ED M VAN
IPC: E04H17/04
Filed: 1990-10-15
Abstract: Partitions, covers and screens constructed with flexible flat material, are arranged to have at least three adjoining sections of material from the roll. The edges of the sections are joined leaving regularly spaced gaps for stay supports or similar. The three sections from the roll of flexible flat material may pref. be produced on a knitting machine. This may be warp knitting with Raschel facilites, in which case it can be arranged for periodical slits to be left near the edges of the material, aligned to coincide in the three sections. The posts (32) would then be pushed through the slits to hold the screen material. To reinforce the slits, the knitted material may be made from a thermo-plastic synthetic, and these can be heat set in the manner of buttonholes. Insertion of fibrillated plastic as extra warp at the region of the slits may be necessary to provide the thermo setting. This may be carried out with the three separate sections being produced at the same time on a Raschel warp knitting machine. It is also feasible to stitch buttonholes in knitted material of any form, to to cross stitch by zig-zag stitch along the adjacent edges of the cloth sections. In this case, there are regularly spaced gaps in the stitching, and on vertically suspended screens, a stay support to intertwined, or bands or cords may be dropped from the top stretcher.

Title: Machine for filling bottles with liquid containing gas - has rotating table which operates valves in required sequence
Inventor: BALDAUF MANFRED
IPC: B67C3/10
Filed: 1990-11-26
Abstract: A machine for filling bottles with a liquid, with a gaseous content, has a rotating table which receives the empty bottles.  As the table rotates it brings each bottle in turn under the filler head (8) and at the same time it opens and closes valves by means of sensors which move over stationary cams. The vacuum valve (17) is first opened and then closed, followed by the opening and closing of the pressurising valve (13) and finally the opening and closing of the valve (11).  This allows the liquid (4) from the tank (3) to flow into the bottle. USE - Filling bottles with beverages containing carbon dioxide.
