Patent DE-4224359-C1 (DE)
IPC: B62D11/18
Filed: 1992-07-23
Granted: 1993-05-27
Abstract: The invention concerns a control device for a vehicle propulsion drive comprising two hydrostatic transmissions (3, 4) with adjustable reduction ratios, each transmission comprising a hydraulic pump (12, 13) and a hydraulic motor (14, 15). The transmissions are connected up to drive two vehicle-track assemblies (18, 19). Each transmission has an adjustment device (30, 24; 31, 25) controlled by control signals (vl, vr) to adjust the reduction ratio, with a control section including target-value setting (5) and signal-processing (42, 43) facilities. The target-value setting facility sets reduction-ratio target values for each hydrostatic transmission, using for each a movable control lever (36, 37), and generates target-value signals (sl, sr) while the signal-processing facility (42, 43) processes the target-value signals to give control signals and outputs these control signals. In order to avoid spurious changes in vehicle speed, the signal-processing facility is designed to generate a min./max. window from the target-value signals (sl, sr) in accordance with the relationships: min. = minimum (sl, sr) and max. = maximum (sl, sr), and to determine the control signals (vl, vr) to be output in accordance with the equations: vl = vm + (sl + sr) and vr = vm + (sr - sl) when the means value vm = (vl + vr)/2 of the control signals (vl, vr) determined in a preceding signal-processing step lies within the min./max. window, or to correct the control signals (vl, vr) determined in a preceding signal-processing step in order to determine the control signals (vl, vr) to be output in accordance with the equations: vm<min.: vl = vl + (min.-vm), vr = vr + (min.-vm), vm = min.; vm>max.: vl = vl - (vm - max.), vr = vr - (vm - max.), vm - max., when the mean value (vm) of the control signals (vl, vr) determined in the preceding signal-processing step lies outside the min./max. window.

Title: Increasing tear resistance in heat shrinkable plastic film - extruding strip, partially cross-linking, stretching at temp. below crystalline m.pt. and finally cross-linking during shrinkage.
Inventor: NICOLAI NORBERT DR
IPC: B29C55/02
Filed: 1993-04-22
Granted: 1994-05-05
Abstract: The method involves extruding a plastic strip at a temp. below a peroxide reaction temp. and initiating partial crosslinking. The strip is stretched at a temp. below the crystalline m.pt of the plastic. The strip is fully crosslinked during the heat shrinking stage. Pref. initial cross-linking involves using a mixture of peroxides, with different reaction temps. and times and can be initiated by irradiation, peroxide and/or silane. The degree of crosslinking can be varied by passing the plastic strip through a salt bath or steam and altering the passage time or temp.. The partially crosslinked strip is heated to a temp. below the crystalline m.pt. by passing through oil or heating with microwaves before stretching. Final crosslinking is achieved by heating the peroxide with microwaves and simultaneously cooling the surface. USE/ADVANTAGE - Producing heat shrinkable product, esp. for cable connectors or branches. Increased tear resistance and eased opening of shrink-wrapped component.

Title: Method for determining a wear-dependent braking force distribution
Inventor: TOEPFER BERNHARD DR ING
IPC: B60T13/66
Filed: 1993-08-05
Granted: 1994-12-01
Abstract: The invention relates to a method for wear-dependent braking force distribution. On the basis of the determination of the wear of the brake linings, it is known to carry out a distribution of the braking forces which compensates for this wear. Known devices are limited to regions of the lowest braking pressures, since otherwise adhesion problems occur. The present invention prevents adhesion problems without having to be limited, in the process, to the "lowest" braking pressures. Only in the case of braking above, for example, 0.3 g, occurring very seldom in operation, or in the case of a "learned" adhesion threshold, which is in practice limited to really critical braking situations, is the wear control not used. Moreover, according to the invention, the control interventions are carried out with the aim of bringing about compensated wear in the long term only; instead of only one wear compensation, the aim is parallel wear.

Title: Method and appts. for cooling, esp. for quenching workpieces by gases
Inventor: MELBER ALBRECHT DR ING
IPC: C21D1/613

Granted: 1995-08-24
Abstract: Cooling (esp. quenching) of workpieces by gases takes place in a heat treatment furnace (1) in which the circulating gases are cooled down on cooling surfaces (12) of at least one heat exchanger (11) located in the furnace and joined by piping (13a,13b) to an external heat extraction unit (17) with a liquid cooling medium. The storage volume (20) for a hydrous cooling medium in this unit is kept under a reduced pressure so that at least a part of the hydrous phase of the volume (20) is evaporated for extraction of heat from the heat exchanger (11). The tank (18) for the storage volume is connected to a vacuum pump (24).
