Patent DE-3821547-A1 (DE)
Title: Pressure measuring device
Inventor: SCHULZ WINFRIED DR ING
IPC: G01L9/00
Filed: 1988-06-23
Abstract: The invention relates to a pressure measuring device with an inductive pick-off system (1), which consists of at least one electromagnetic coil (5, 6) and an armature (4), which can be displaced relative to the coil and is carried by a connecting part (12). Because of the different thermal expansion coefficients of the materials used for the components, measuring errors and fatigue of the joint between armature (4) and connecting part (12) can arise during temperature changes. These measuring errors brought about by temperature changes and the loading of the joint can be avoided in that the expansion coefficient of the material used for the armature (4) corresponds to the expansion coefficient of the material used for the connecting part (12). Pressure measurement and differential pressure measurement. <IMAGE>

Patent DE-3842866-A1 (DE)
Title: Dispenser
Inventor: VOELKER GUENTER
IPC: G07F11/26
Filed: 1988-12-20
Abstract: The invention relates to an apparatus for the presentation and automatic dispensing of bottle and can products, the apparatus comprising a toothed belt which is clamped between toothed-belt pulleys, with the result that a closed conveyor band is obtained. The toothed belt is equipped with bosses on its conveying surface, in such a way that the bottles or cans are clamped between the bosses. Ejection of a bottle takes place in the region of deflection of the toothed belt as a result of the spreading of the bosses in this region, the said spreading proceeding automatically during the rotation of the toothed belt. In this apparatus, the further transport and the ejection take place simultaneously, without the use of complicated blocking or ejecting mechanisms.

Title: Transloading point for containers - from and onto railway trucks, consists of platforms, rails and conveyors in form of lifts and ramps
Inventor: HIMMELHEBER MAX DIPL ING
IPC: B65G63/00
Filed: 1989-05-30
Abstract: The contents of the container (24,12) are unloaded onto railway trucks (3), or vice versa, from platforms (5,15,25) next to parallel rails (20).  A conveyor (10) enables the containers (4') crosswise to the direction of the rails to be transported in an underpass (9) from one platform to another (5,15,25). The conveyor between the platforms (5,15,25) and the underpass (9) is in the form of lifts (21,22) for the containers (4',12,24), or ramps. The  platforms (5,15,25) are more than twice as wide as the containers. USE/ADVANTAGE - Containers are more quickly transloaded to and from trains in a way which does not require the containers to be separated from each other.
Patent DE-3917759-A1 (DE)
Inventor: BUSSELL MITCHELL L
IPC: F16C19/48
Filed: 1989-05-31
Abstract: A bearing assembly comprises an inner ring (20) and a cage-and-roller subassembly (30).

Title: Soil consolidation - by injection of organo-mineral resin contg. isocyanate and modified water glass
Inventor: GRDES KNUD DR
IPC: C09K17/46
Filed: 1989-07-04
Abstract: Loose ground including water bearing soil is stabilised by the injection of organo-mineral resin which also seals it. The two components of the mixt. react with each other and join/solidify the grains. The pref. mixture consists of isocyanate and modified water glass, mixed in a ratio of 1:1. An area between the sole (2) and the wall (3) of a building trench (1) has been sealed and solidified by inserting a tube (4) in loose ground (10) and infusing a two-component mixture to produce the cyanate shell (8) around the injected material. The foam factor is set as up to 1:30. ADVANTAGE - This creates a stabilising and sealing procedure for loose ground which is compatible with ground water and results in a uniformly defined injection area.

Title: Delamination of laminated punching plates - immersion in incompressible fluid and application of ultrasonic waves ensures free sepn. of steel plates from laminated facings
Inventor: MEURER BERND-CLAUS
IPC: B08B3/12
Filed: 1989-09-05
Abstract: Delamination of laminated structures (A) whose individual layers are adhesively bonded together can be achieved by immersion in an incompressible liquid, typically water or caustic soda soln. at 60-95 deg C then subjecting it to ultrasonic sound waves at 15000-50000 Hz. USE/ADVANTAGE - (A) is necessary in eg the mfr of cartons where male and female punching tools are used. The female is formed of a steel plate to which an upper layer is laminated. The latter is subjected to high stresses by the male punch.  When the upper layer of plastic, cardboard or similar is worn, recovery of the expensive steel plate is necessary for reuse. Changes in tool design also require removal of the upper layer. Easier removal of the upper layer is achieved without mechanical aid, thereby avoiding damage.

Title: Lid-adjusting method on frame esp. car hatchback - uses hinging adjusting member thrusting lid before tightening hinge screws fully
Inventor: BAUER ANDREAS ING GRAD
IPC: E05D11/00
Filed: 1990-03-03
Abstract: The method adjusts the position of a lid on a frame containing an opening, particularly a car hatchback, there being screws securing the hinges and a lock to the frame. The screws (3,4) are  first partly tightened to allow transverse movement of the lid (1) and of the part (2) of the lock on it only by application of an additional force, and to a degree limited by clearance holes (7,8) through which the screws pass. When the lock halves (2,5) engage together, an adjusting member (13) swings about a boss (17) on the frame half (5) of the lock or a hinge half on the frame, being brought by a lug (12) eccentric to the boss into engagement with stops (10,11) at right angles to it. This thrusts the lid into the desired position, after which the screws are tightened right down. ADVANTAGE - Accurate positioning by thrusting the lid in defined directions.
