Title: Control and prediction of course of spark erosion process on spark erosion machine
Inventor: BEHRENS ARNO
IPC: B23H1/02
Filed: 1995-04-05
Abstract: An oscillation decay process - which is superimposed on the gap voltage and is the result of an oscillatory system comprising an energy source, leading to the work gap and the work gap itself - is evaluated by double differentiation and is made available in the form of logic signals so that characterisation of the present and prediction of the future course of the spark erosion process are possible.  The boundary frequencies of the two differentiation stages stand in a fixed ratio to one another, with the frequency of the second stage being higher than that of the first stage.

Patent DE-19530872-A1 (DE)
Title: Mfr. of sand mould in vibration-free manner
Inventor: IBURG JOHANNES
IPC: B22C15/14
Filed: 1995-08-22
Abstract: The moulding machine for compacting moulding sand in a mould box (FK) and for introduction of a pattern (MP) is characterised by the fact that all vertical motions involved in the compaction process, in particular the compacting thrust, are introduced and carried out from above, while the pattern plate lies stationarily on a foundation-near table (MPT). The compaction unit (2; 2a-2e; PR) with the attached frame package (FK, KFR, GPR) is moved downwards relative to the stationary pattern plate. This downward motion is resisted by a spring force which, at the end of the pressing process, lifts the package from the pattern plate without shock or vibration.  The machine foundation intended for taking up the forces during the pressing process is free from cylinder units moving press columns or rams. The upward motion of the frame package (FK, KFR, GPR) is achieved by means of hydraulic springs. At least one of the elements (GPR) is movable relative to another element (FK, KFR) or relative to the stationary pattern plate. The pattern plate with pattern (MP) is held to the stationary table (MPT) by vacuum. The pattern may be provided with nozzles producing an upward air stream against the sand mould to ensure vibration-free separation of the pattern and the mould.

Patent DE-19536582-A1 (DE)
Inventor: KNOBLACH WALTER DR ING
IPC: F17D5/04
Filed: 1995-09-29
Abstract: The invention pertains to a process and device for feeding a predetermined quantity of a test substance (H2) into a monitoring line (2) filled with a test medium (such as air) and used for determining concentration profiles along a given path. In order to move a column of the test medium through the monitoring line (2), the pressure (p) in the monitoring line (2) is raised by actuating a pressure pump or, for the same purpose in an alternative embodiment, lowered by actuating a suction pump (12). A predetermined metered quantity of the test substance (H2) is released automatically when the pressure (p) in the monitoring line (2) passes a predetermined threshold value. Release of the predetermined metered quantity of the test substance (H2), once the latter has been carried by the test medium column, results in a test-peak in a sensor (11) which reacts to the test substance (H2) and is connected to the monitoring line (2). Application: pneumatically controlled test-peak generator.

Also claimed is a device to carry out the process above to find the filter life, having a hollow body (1) with a suction pump (8) at one end and an interchangeable gas filter (2) at the opposite end.  There is a test chamber (3) following this with an outlet (4) to a sampling device (5).  Before the pump there is a valve device linking to the surrounding air and controllable by a computer (18) according to specific characteristic breathing lines and the flow rate in the hollow body measured by a flow sensor (21).

Patent DE-19628980-A1 (DE)
Inventor: BATISTIC IVICA
IPC: B60T8/1755
Filed: 1996-07-18
Abstract: The invention concerns a method of improving ABS control behaviour on cornering. According to the invention, during a cornering-detection process, instead of the standard control mode, a special or cornering-control mode is activated which reduces the braking pressure on the front wheel and/or rear wheel on the inside of the bend. When, in the partial braking range, a threshold value (th) of a wheel speed difference - representing the difference between the totals on each side formed from the speeds of the two wheels on one side of the vehicle - is exceeded, the braking pressure on the front wheel and/or rear wheel on the inside of the bend is reduced until this pressure is below the threshold valve (th, thH) and additionally a hysteresis band (H) again.

Title: Winding electric tape onto large coil e.g. for current generators or transformers
Inventor: JUNIUS HANS-TONI DR ING
IPC: H01F27/25
Filed: 1996-07-18
Abstract: The method provides a deformation free winding of electric tape to a large coil. The electric tape (2) is fed from a tape feed device (5) and is wound onto a rotating coil core (1). The core is a multiple of the width of the tape (2). The tape feeder (5) and the core (1) are movable relative to each other parallel to the core axis. The rotation rate of the core (1) and the relative axial speed between the core (1) and the feeder (5) are computer controlled to be tuned to each other such that the tape (2) is wound in oscillations into successive closely wound layers. At the ends of the large coil the direction of the axial relative movement between the core (1) and the tape feeder (5) is reversed. At least during the last rotation of the core (1) before initiating the direction change at the ends of the large coil, the axial relative speed between the core (1) and the feeder (5) is accelerated for a short time.
