Title: Measurement of small leakage quantities - using variations of column height in connecting vessel with cyclically opened outlet valve
Inventor: STURM DIETER
IPC: G01M3/32
Filed: 1987-04-04
Abstract: The height of the liquid column in a collecting vessel (2) is tested at regular time intervals. The effective leakage quantity is derived from variations in the column height taking into account the relevant boundary conditions. The vessel is cyclically emptied to a defined leakage value via a controllable outlet valve (7). When a predefined leakage quantity is exceeded only certain level heights are indicated and the outlet valve is held open. The leakage quantity not flowing out through the valve (7) is fed via an upper overflow device (6) to the outflow line. The valve is controlled by a microcomputer fed by an electrical level probe (4). USE/ADVANTAGE - E.g. for nuclear reactor, chem. industry. For small leakage quantities flowing not under pressure into collecting container. Direct indication of leakage using minimal number of moving parts.

Title: Apparatus for producing plastic bags
Inventor: HETTLER ALBERT
IPC: B31B70/00
Filed: 1988-03-05
Abstract: For producing plastic bags with tubular guides (5) moulded onto the free flap ends for drawing cords (6, 7), edge clearances (8) are punched in before drawing in the cords and, in a transverse mid-plane (10) or separating-welding plane (18), the cords are drawn out and tied by two opposing knotters (19, 191). During this operation, force-loaded tongues (28) hold the cords (6, 7) in a retarding manner on bearing strips (34). If the lift (22) is moved into the upper end position, shown by broken lines, the cords are drawn out of the tubular guides against this retarding force and are divided up by the middle shears (25). The cord ends are assigned to opposing sides of the two knotters (19, 191) by means of counter-movable feeding elements. After cutting off excess lengths by the knot shears (29), the knot pullers (30) detach the cords (6, 7) from the knotters, so that after lowering the lift element (22) underneath the bearing surface and relieving the tongues (28), the bags (11) can be further conveyed in a cyclical manner. Since the cords are under prestress the whole time during the working cycle, the individual operations can be carried out at a high cycle rate quickly and one immediately after the other. <IMAGE>

Inventor: HESSMERT ULRICH DIPL ING
IPC: F02D45/00
Filed: 1988-06-28
Abstract: A drive-slip regulating system prevents control errors due to wheel vibrations. For this purpose, the quotient Q of the engine speed and the measured speed of the driven wheels is derived and compared with predetermined speed-dependent reference quotients. An artificial wheel speed is derived from the nearest reference quotients and the engine speed and, when wheel vibrations are detected (i.e., when the quotient deviates from the nearest reference quotients by a given value), is either used in the system as a wheel speed or its increase is used to limit the increase in the actual wheel speeds.

Title: CNC apparatus of modular construction and usable in a mobile or stationary manner for the working of surfaces of any size with interchangeable effectors in accordance with the requirements
IPC: B05B12/00
Filed: 1989-01-05
Abstract: CNC apparatus which is of modular construction, can be used in a mobile and/or stationary manner and is flexibly adaptable to the working of surfaces of any size with interchangeable effectors in accordance with the requirements. The invention concerns an apparatus and a method which permits through the use of a computer the transfer of computer-aided designs (e.g. CAD) to surfaces which hitherto could only be worked manually. In this way, error-free progress from the design stage to completion is obtained. This enables, for example, house facades and large billboards to be automatically fashioned in a short time. The increase in quality obtainable by the invention guarantees an exactly definable coating thickness of the paint application provided and high reproducibility, which is manually unobtainable. The scaffolding required, for example, during manual execution is dispensed with. This avoids the expenditure on services which do not help to increase the value of the building.
