Patent DE-3901935-A1 (DE)
Title: Metering mechanism for fluid or pasty media
Inventor: BINDLER UWE
IPC: A23G9/28
Filed: 1989-01-24
Abstract: The invention relates to a metering mechanism for fluid or pasty media which makes possible the metering of small quantities, successively or in parallel. For this purpose, a metering piston 12 designed as a ring piston and a valve rotor 14 designed as the core of the ring piston are mounted concentrically to each other in a housing 1 and positioned so as to be mutually rotatable. The metering piston 12, designed as a ring piston, has a recess designed as a ring-segment-like filling space 13, which can be subdivided into chambers by ring-segment-like discs 12a, 12b, 12c carried by the metering piston. By rotating the valve rotor 14, the filling space 13 or respectively its chambers can be connected to one or more discharge openings 6, 7, 8, 9, so that the medium contained in the filling space 13 is conveyed out by rotating the metering piston 12. In another rotary position of the valve rotor 14, on the other hand, the suction opening 11 is connected to the filling space 13, so that the filling space 13 can be filled by rotating the metering piston in the opposite direction. <IMAGE>

Inventor: STUTZ ERHARD
IPC: B65G33/06
Filed: 1989-04-22
Abstract: Process and device for transporting and stacking essentially flat objects, in particular flat bags. The spaced flat objects or bags arrive one behind the other along an axis passing through the centre of the surface of the objects, are transported over several conveying sections to a stacking station and placed in a stack of predetermined size. Before the objects or bags are stacked, the individual objects or bags are introduced laterally into the thread of a screw conveyor or a spiral conveyor, separated one behind the other by the thread and transported to the stacking station in a position essentially parallel to the surface of the thread.

Title: Removing distn. residues from container - by stirrer arms rotating in spring-loaded edge contact with inclined floor
Inventor: FUEHRING HEINRICH DIPL ING
IPC: B01D3/00
Filed: 1989-04-29
Abstract: Residues collecting in a distn. vessel are forced out from an aperturee at the container base.  Discharge propulsion force derives from the rotating car or arms of the motor-driven stirrer with an axial drive shaft; the  motor shaft itself is externally mounted. The floor over which the rotating radical arms move is somewhat inclined down towards the discharge aperture side.  The vessel is cylindrical and the stirrer arms, pref. of flattened S-shape, are resiliently held against the inclined floor by a spring mounted on the stirrer shaft.  Container inernal conditions are observed from a spy-glass in the cover. USE - For treating contaminated solvent slurry from dry cleaning plant.  Removal of solids is simple and automatic.
Patent DE-3919560-A1 (DE)
Title: Clamping device with two clamping jaws arranged for centred clamping on a guide bed
Inventor: SPENGLER ERNST
IPC: B25B1/06
Filed: 1989-06-15
Abstract: In one clamping jaw there is arranged a source of power, e.g. a hydraulically driven booster, which via its pressing piston exerts the action force on said clamping jaw. The reaction force is transmitted by the pressure cylinder of the booster, via the rod and the clamping screw, to the second clamping jaw. The synchronising device, situated in the bed of the clamping device, consists of a synchronising shaft which is arranged centrally in the bed of the clamping device and on which the synchronising centre piece is pivotably mounted. From the latter, in each case one lug, pivotably arranged on the pin, guides the movement via the bolts to the holders onto the clamping jaws which thus perform a precisely matching counter movement.

Title: Maintaining data consistency in multiprocessor system - controlling working memory via buffer memory to store data to be transmitted in intermediate stage
Inventor: DAHLEM KARL-JOSEF DR
IPC: G06F12/0811
Filed: 1990-02-20
Abstract: In the selection of the operational storage device (ASP), via a pre-switched buffer (SIC) for interim storage of data to be transferred between the operational storage device and the private cache stores (STCo to STCm) operating on the store-through principle, content identifiers individually assigned to the private cache stores are stored for each entry in the buffer.  These show in which of the private cache stores data of the same address can be available. In the access control procedure (MAC) of the operational storage device, copies (TK) of control data are directed from the individual cache stores.  When write requests are made, the cache stores-identified through the contents identifiers- are first selected (viz. signals STRO-BEx) and checked in the access control procedure through these copies to see if data of the same address are present and are to be declared as invalid. The appts. can segment the operational storage device into separately selectable modules (ASPo to ASPi) with individual buffers (SICo to SICi), which can be modelled as chache stores operating on the  store-in principle. ADVANTAGE - Improves up-dating of copies in cache memories.

Title: Ventilation of shooting gallery - involves air inlet in ceiling from which air flows horizontally to target end of gallery
Inventor: FITZNER KLAUS DR ING
IPC: B08B5/02
Filed: 1990-03-28
Abstract: The ventilation system for a shooting gallery (1) has an air inlet in the ceiling at the end of the gallery (7) from which the shots are fired.  The air flow is controlled to produce a laminar flow (12) which flows downwards and is then deflected in the horizontal direction towards the target end of the gallery. This horizontal flow of the ventilating air takes away all smoke, fumes, etc. produced by the firing of the guns and maintains a supply of fresh air to the persons firing the guns. USE - Ventilation of shooting galleries.

Title: Creating pressure for conveying material - involves introducing gas through holes in container base by impulses
Inventor: FASSBINDER HANS-GEORG DR RER N
IPC: B65G53/12
Filed: 1990-10-09
Abstract: The method of creating high pressure in pneumatic containers consists of introducing the gas used for creating the pressure through one or more holes in the bottom or base of the pressurised container. The amount of the impulses is controlled by the gas pressure reached and is roughly proportional to the absolute gas pressure. The time between the impulses is kept constant. The impulse duration with a constant flow speed is regulated so that it is proportional to the pressure in the container. USE/ADVANTAGE - The method is particularly for pneumatically conveying fine granular material.
Patent DE-4034436-A1 (DE)
Inventor: BRAUN MARTIN
IPC: B21B31/10
Filed: 1990-10-29
Abstract: The invention relates to an apparatus by means of which, to change the rolls, the chocks of the upper working roll can be supported on those of the lower working roll in such a way that the rolls rest freely one above the other and their shells do not touch. According to the invention, the chocks of one of the rolls are equipped with swivellable supporting levers which, in their normal position, engage around flanks of the opposite chocks and, during adjustments of the stand, are capable of sliding on the said flanks. To change the rolls, however, the upper working roll is raised together with its chocks in such a way that the spring-loaded supporting levers can swivel inwards and engage in grooves in the opposite chock and, during the lowering of the upper working roll, are supported against the base of these grooves. During the installation of a set of rolls, the upper working roll is likewise lifted and the supporting levers are then spread apart, for example by means of a drive or locking devices, so that, as the upper working roll is lowered, they slide past the groove supporting them and can come to rest against the flanks of the opposite chock.
