Filed: 1988-03-21
Abstract: A device for taking up play and restoring play between coupling bolt and coupling ring of a trailer coupling comprises a bolt which is movable in a cylinder and an abutment body which is acted upon by this cylinder and during driving keeps the coupling parts in mutual abutment under the effect of the hydraulic compression means which is inhibited from flowing away and rests against the piston, it being possible to drive the piston in the direction of the take up of play and to refill the high-pressure cylinder space, which increases when play is taken up, from an hydraulic compression means supply and it being possible to empty the high-pressure cylinder space in order to release the abutment body. In this case, the piston can be driven in the direction of the take up of play by applying pressure from the compression means supply. <IMAGE>

Title: Rolling pedestal for containers, e.g. beer crates, water crates and other containers (crates, cardboard boxes, canisters)
Inventor: OSTERMANN DIETER
IPC: B62B5/00
Filed: 1988-11-04
Abstract: The transport movement of containers under racks, cabinets and the like requires relatively large forces, wears the ground (concrete, jointless floor, floor covering) and damages the container and, under certain circumstances, the back wall against which the containers are pushed. This can lead, in certain circumstances, e.g. in the case of liquid containers, to their destruction. The novel rolling pedestal is to serve to facilitate the transport movement of containers of all types under racks, cabinets and the like and to prevent abrasion, damage to the container and damage to the rear wall, and to prevent the container from sliding off the rolling pedestal. For this purpose, the rolling pedestal is equipped with three to four wheels for "sliding", one or two wall stop buffers for protecting the wall, and with 2 limit rails for preventing the container from sliding off.

Title: Railway train with special carriages - can be coupled or uncoupled to receive or set down passengers without stopping train
Inventor: CHRISTOPH BERTRAM
IPC: B61B1/00
Filed: 1989-04-10
Abstract: The track and carriage system can increase the speed of railway passenger traffic. Passengers wishing to leave train enter a special carriage before reaching their destination. This special carriage stops at the required station whilst the remaining part of the train goes through the station without stopping. Passengers wishing to board the train board a second special carriage which leaves the station ahead of the train. The train catches up with this carriage which is then coupled to the train. The coupling and uncoupling of the special carriage is facilitated by auxiliary axles (1) with wheels (2,3) set at a wider gauge which are attached to the carriage and can retracted or lowered to run on auxiliary rails (4,5). USE - Passenger railways.
Patent DE-3912294-A1 (DE)
Title: Ground (floor) gully
Inventor: WEILER WALTER DIPL ING
IPC: E03C1/23
Filed: 1989-04-14
Abstract: Ground gully in wet rooms or sanitary blocks are used only very infrequently for the discharge of water. The rest of the time they remain open and collect dirt very quickly. The odour seal can dry out. The solution of these problems is derived from the idea that it is more expedient to open the gully only in the presence of water and to keep it closed for the rest of the time. The ground gully according to the invention thus has a cover which can be opened and also closed again by a preferably remote-controlled device.

Title: Antilocking hydraulic braking system for motor vehicle - includes throttle valves inserted in respective brake lines supplied by pump between main and respective wheel brake cylinders
Inventor: BURGDORF JOCHEN DIPL ING
IPC: B60T8/44
Filed: 1989-06-17
Abstract: The return lines (10) communicate with a pressure medium reservoir (4). Solenoid operated outlet valves (11) are respectively arranged in the return lines and in their rest position block them. The throttle valves (8) respectively arranged in the brake lines (6) have a first unthrottled and a second throttled position for the communication existing between the respective wheel brake and the main braking cylinder. A sensor detects the angular speed of the wheel to be braked and the sensor signal is evaluated by an electronic evaluation unit, and produces a signal for the pump drive (12, 13) and the solenoid valves (11). Each throttle valve (8) is closed by means of a control line (19) at the output of the pump (12, 13), so that the pressure at the pump output moves the throttle valve from the unthrottled to the throttled position. The pumps (12, 13) are driven by a common motor and sensors establish tendency of wheels to lock, so that the braking system can be switched to anti-locking or regulation mode. ADVANTAGE - Reduces number of valves and gives esp. rapid pressure redn..

IPC: C07K16/20
Filed: 1989-10-13
Abstract: Qualitative and quantitative determination of circulating Toxoplasma antigen (zTgA) and of endo- and cysto-zoites of T.gondii uses the monoclonal antibodies (MAb) MAM-1B2, -4F6 or -5B10 as immune reagents. Pref MAb are immobilised on microtitre plates, foils or spherical objects, eg beads or rods of polystyrene, PVC, etc.  Alternatively, they are adsorbed on or covalently bound to a latex, bentonite, erythrocytes or carrier materials for immuno-affinity chromatography. USE/ADVANTAGE m using MAb have high specificity, sensitivity and reproducibility and can be standardised (contrast conventional methods using antisera). Detection of zTgA is used to diagnose infections in new-born babies, pregnant women, AIDS patients and subjects undergoing immunosuppressive treatments. MAb also provide very specific detection of endo- and cysto-zoites in tissues in routine histological diagnosis. When coupled to chromatographic carriers, MAb are used to recover antigenic fractions from crude T.gondii antigens.
