Title: Viscous fluid metering control valve with rotary stepping motor - is adjusted according to outlet pressure and inlet temp. controlling flow into pneumatically variable suction chamber
Inventor: HOEHN HANS GEORG
IPC: F16K31/50
Filed: 1992-05-29
Abstract: The passage between the inlet (3) and the outlet (5) is controlled by a tapered needle (8) and seating (4). The needle is moved axially between fully closed and wide-open positions by a stepping motor (23) driving a threaded spindle (12) on which a nut (11) converts the rotation into a linear movement. The motor is controlled by signals from a pressure transducer (28) in the outlet and a thermistor (29) in the inlet. The amt. of fluid dispensed depends on the vol. of a reverse suction chamber (32) varied by a piston (34) in a single-acting pneumatic cylinder (31). USE/ADVANTAGE - Can be part of industrial robot. For fluids with high or strongly temp.-dependent viscosity, e.g. for forming adhesive connections. Very rapid and precise metering even under high pressure is possible with simple and compact valve.

Patent DE-4230832-A1 (DE)
Title: Suction tube, i.e. diffuser, for hydro-electric power station - has constant interior convex curve at narrowest place near turbine wheel, connects wheel to underwater junction and reduces drive water flow speed.
Inventor: VALENTIN FRANZ PROF DR
IPC: F03B13/08
Filed: 1992-09-15
Abstract: The suction tube connects a turbine wheel to an underwater junction, and slows down drive water emanating form the turbine. The turbine wheel has a current-linkage-jet ring gap (11), that is not rotary symmetrical, arranged around its outer circumference. This causes a strong Coanda-deviation or a Coanda-divergence. The current in the vicinity of the Coanda-deflection conforms to the top of the upper exit wall of the suction tube. The tangential components of the ring-jet occuring outside the optimal operation of the turbine, on application of the current, occur at the top of the tube. USE/ADVANTAGE - For overpressure turbines. Free from previous technical restrictions, e.g. long length, opening degree less than 8 degrees. Better uniform current, thus lower losses.
Patent DE-4231635-A1 (DE)
Inventor: REICHMANN HANS HELMUT
IPC: B67D1/08
Filed: 1992-09-22
Abstract: A container (1) for storing and transporting pourable media, preferably liquids, has an undeformable outer container (2) and an inner container (3) removably set therein designed as a flexible but substantially non-stretchable bag, sack or the like. The folded or collapsed bag, sack or the like may be brought into or out of the stiff container (2) through a tube (4). The inner container (3) has also a tube (5) which can be removably set into the tube (4) of the undeformable outer container (3). A flow path (6) is kept free between both tubes (4 and 5) which corresponds to the space (7) between the outer (2) and inner (3) containers. The essential characteristic is that two separate flow paths (18 and 28) are provided or designed in the tube (5) of the inner container (3). The flow path (18) leads directly into the inner container (3) and the other flow path (28) leads into the inner container (3) through a submerged tube (21) or hose. A common self-closing locking member (26) is associated to both flow paths (18 and 28) inside the tube (5) of the inner container (3). A closure cap (31) for both pipes (4 and 5) and the common locking member (26) or a filling and/or emptying fitting (38) may be selectively coupled to the tube (4) of the outer container (3); said fittings correspond to all three flow paths (6, 18 and 28).

Patent DE-4303031-A1 (DE)
Title: Limit switch operation for control of IC card reading
Inventor: DOERR MARTIN
IPC: G06K7/00
Filed: 1993-02-03
Abstract: A chip card reader has the card inserted into a carrier (3) that is then displaced linearly within the housing until a latched position is reached and a switch operated. The limit switch is mounted at the seat of the access slot and is open as long as the card carrier is in the fully inserted position. In this position the carrier is latched by a projecting pin (27) that engages a slot (25) on a bar (26). The bar is spring supported and deflects downwards as the pin rides onto the top surface when the carrier is removed. This causes actuation of the limit switch.

Inventor: STIPPLER KURT DIPL ING DR
IPC: C12C7/16
Filed: 1993-07-19
Abstract: The invention relates to a process and device for controlling the wort flow from a lauter tub. To shorten the run-off time, according to the invention, a second, increased outflow quantity is determined during the overall cycle of a brew (pre-mash, after-mash) based on a predetermined outflow quantity of the wort which is to be attained within a given time. The increase in the outflow quantity per unit time (increase value) needed to reach the second outflow quantity is found from these figures and this increase value is used as a reference to control an outflow regulator.

Patent DE-4331789-A1 (DE)
Title: Ball-type sliding bearing with oil lubrication
Inventor: SEIBOLD MARTIN
IPC: F16C33/10
Filed: 1993-09-18
Abstract: Known sliding bearings make use of plastic and this has a disadvantageous effect as regards length of service life. Other sliding bearings have multi-part sliding surfaces and this leads to high production costs. The new ball-type sliding bearing is intended to eliminate these disadvantages. To produce an inexpensive ball-type sliding bearing with a long life, a one-piece inner ring (1b) is surrounded over a large area by an outer ring (3a pipe section made of brass), leaving an oil gap (2) of about 0.03 mm. This sliding bearing can be fixed in the head of a rod by means of brazing solder (5). The ball-type sliding bearing with oil lubrication operates very smoothly and precisely and, by virtue of the large-area surround (3a), has a long life and is inexpensive to manufacture. The properties of the ball-type sliding bearing make it suitable for various tasks associated with mechanical force/power transmission in models, machines and musical instruments. <IMAGE>

Title: Compressed-air reservoir in commercial vehicles
Inventor: BERNHARD WOLFGANG DIPL ING
IPC: B60R16/08
Filed: 1994-03-03
Abstract: The invention relates to a compressed-air reservoir (1) of a commercial vehicle, in particular a lorry or a bus, the outer wall (2) of which is provided with an anti-corrosive layer on its inside. This anti-corrosive layer normally consists of enamelling which can flake off on account of stress caused during operation, which can lead to the failure of the entire pressure and control system of the compressed-air unit. The object of the invention is therefore to design the outer wall (2) of a compressed-air reservoir (1) in such a way that the flaking-off of parts of its inner layer serving as corrosion protection can be avoided under all conditions of use of the vehicle and it can be produced in a simple and efficient manner. This object is achieved according to the invention in that the outer wall (2) of the compressed-air reservoir (1) is produced from a double-layer composite material, the two layers (3, 4) of which are undetachably connected to one another, the outer layer (3), which ensures the compressive strength of the compressed-air reservoir (1), being made of a steel material and the inner layer (4) being made of an anti-corrosive material. <IMAGE>
