Patent DE-3730814-A1 (DE)
Title: Cementlessly implanted, self-tensioning hip joint stem
Inventor: FELMET GERNOT DR MED
IPC: A61F2/36
Filed: 1987-09-14
Abstract: The hip joint stem which is usually implanted cementlessly is only insufficiently adapted to the shape of the medullary space because it has to be manufactured in a specific number of sizes. Due to vibrations in the proximal stem area, loosening, is to be noticed, in particular in long-stem prostheses. It is the object of the invention to stop this loosening mechanism by providing individual support on the lateral cortical substance or in the greater trochanter of the femur. The invention can be implemented on any conceivable prosthetic stem. According to the invention, a spreading plate (2) projecting beyond a spring leaf mechanism (3) is attached to a prosthetic stem (1) for bearing against the lateral cortical substance in such a manner that it spreads away from the prosthetic stem (1) with pretensioning of the spring leaf mechanism (3) and widening of the cross-section, in order to support the stem against the lateral cortical substance. The maximum spreading and hence the maximum widening of the cross-section of the stem are chosen such that the spreading plate (2) can be repositioned by the pre-load of the spring leaf mechanism (3)if there is a tendancy to loosening. The spring leaf mechanism (3) can ideally be produced from one piece. The mechanism can be replaced by a joint-like connection and a spring force in the gap (5). A cross strut (4) is used as spacer on increasing spreading of the spreading plate (2). <IMAGE>

Title: Parlour game, "selecting numbers for betting games", by means of magnetic keys, manually
Inventor: SCHIFFERS HILDE
IPC: A63F3/08
Filed: 1987-12-14
Abstract: The game is a fascinating one for young people and adults. The magnetic force is utilised, in a playing box of lasting value which is proof against rust, having a stainless steel covering plate, principally standing upright (like a cupboard) and a manual magnetic key. The technical balance and machining of the magnetic partner is made possible by a stainless steel disc of about 130 mm times 130 mm with the genuine parchment surface fixed thereto, measuring about 120 mm times 125 mm, into which the numbers from one to fifty inclusive are irregularly introduced together with partial colouring, suspended freely by means of a magnetic key directly below the cover of the metal surface of the box into the built-in postage stamp magnifying glass, diameter 0 40 mm, projecting three-dimensionally to 20 mm, to make visible, specifically at 17 mm, and to retain, with the magnetic key, which is held and guided by a handle, above the rust-proof stainless metal covering plate, into which a cavalry scene is permanently dot-printed in a slightly recessed manner. The game can be employed usefully and commercially for betting games which need the numbers from one to fifty inclusive. Guessing games are also possible.
Patent DE-3806257-A1 (DE)
Title: Method of painting motor-vehicle bodies or components thereof
Inventor: FAIX ZDENEK DIPL CHEM
IPC: B05D7/16
Filed: 1988-02-27
Abstract: The present invention relates to a method for painting motor-vehicle bodies or components thereof with at least two or more coats of paint. In the prior art with so-called "wet-in-wet" painting there have time and again been problems involving the risk of a plurality of layers of paint applied in series slipping. The previously known painting methods have therefore also operated with relatively long vehicle-body standing times between the separate stages of the paint application. The invention provides a remedy for this by virtue of the fact that drying by means of IR radiation is carried out between the coats of paint. The method according to the invention thus ensures that a further layer of paint for decorative purposes or a protective layer may be applied, even in very thick layers with an abrasion-resistant finish, without shearing forces causing the first layer to slip. At the same time, it is ensured that the operation can be carried out continuously without prolonged standing times for the vehicle body.

Title: Valve-block unit
Inventor: HAYN HOLGER VON
IPC: B60T15/02
Filed: 1988-03-30
Abstract: A description is given of a valve-block unit, particularly for an anti-lock system, which comprises a plurality of solenoid valves. The coils (29) of the solenoid valves and the cover (16) project beyond the reduced-weight valve-holding body (13). The invention proposes to compensate for the outside dimensions of the valve-holding body (13), on the one hand, and of the cover (16), on the other hand, by attaching a frame (23) composed of plastic and designed as a profiled body. The frame (23) is clamped to the valve-holding body (13) by a strap retainer (27). The cover of the valve-block unit is secured on the frame and hence on the valve-holding body by means of a snap connection (24). The invention provides a simple, leak-tight and secure connection between a valve-holding body of reduced weight and the cover. <IMAGE>

Title: Tactile sensor
Inventor: FRITZ HARALD DIPL ING
IPC: G06F3/045
Filed: 1988-09-29
Abstract: The invention relates to a tactile sensor having at least two sensor electrodes (3, 5; 2, 4) on a sensor surface which are arranged opposite one another and enclose the sensor surface. The sensor surface is a conductive mat whose conductivity can be varied by pressure. In order in addition to the information on the centroid of an object bearing against the sensor surface to obtain information on the extent of said object, a constant current source (10) is connected between two opposite sensor surfaces (3, 5; 2, 4), and the extent of the object can be derived from the variation in the voltage (US) applied to these sensor electrodes (3, 5; 2, 4). The invention can be applied chiefly in the case of sensors in gripper arms of industrial robots. <IMAGE>

Abstract: It is provided that a transport device 4 for aqueous sludge transports this through a transport pipe 1 to a filter press 3, that a metering apparatus 24 for floculating agent is connected to the transport pipe 1 and that a flock measurement apparatus 11 is assigned to the conditioned sludge upstream of the filter press 3. It is desired in this case that a change in the floculating agent addition improving the conditioning influence the rate of the floculating agent to be added as insignificantly as possible. This is achieved by the transport device 4 for sludge and the metering apparatus 24 for floculating agent being controlled 13 with respect to a constant ratio of the rate of floculating agent to the rate of the unconditioned sludge, by a tank 31 for floculating agent stock solution and a tank 28 for make up water each being connected via a feed tube 32, 29 to a mixer device 24 which is assigned to the metering apparatus 24 and by a metering device 35 being provided in the feed tube 32 for stock solution, which metering device 35 is connected to the measurement apparatus 11. Since the improvement in sludge conditioning is only induced by the rate of the stock solution introduced, the control only acts on the rate of the introduced stock solution. <IMAGE>

Inventor: BORRMANN LOTHAR DR ING
IPC: G06F12/1072
Filed: 1989-07-07
Abstract: The physical memories of the computers in a parallel-computer system form a virtual memory which constitutes a virtual address space. The virtual address space is subdivided into segments which in turn are subdivided into pages. The physical pages are stored in the physical memories of the computers. When the computers in the parallel-computer system carry out a process, this virtual address space is allocated to them. During processing, the virtual addresses are converted to physical addresses and at the same time a check is carried out to determine whether the memory cell in the memory which is allocated to a physical address is stored in the memory of the accessing computer or in the memory of another computer. When the corresponding physical memory page is stored in the memory of another computer, a copy of this page is made and transmitted to the accessing computer which can then access this copy as a local page. Changes on the local page can also be made on the original page. Copies of this page present in other computers are also updated. Updating can be carried out synchronously when certain events occur during the execution of a process.
