IPC: A21B1/24
Filed: 1996-04-11
Abstract: This procedure is for the automatic treatment and handling of goods to be refrigerated, cooked goods and baked wares, i.e. bread, cakes and/or pastries.  After any necessary treatment, in this original method, the food is exposed intentionally to a hot or cold airstream. The cold/hot flow enters a refrigeration/cooking chamber (I) to flow directly around the wares to be refrigerated/cooked and/or the baking wares.  The flow of residual cold/heat leaves the refrigeration/cooking space, is filtered and returned to the refrigerating- (III)/heating chamber (II). Also claimed is the equipment for the procedure, consisting of a cooking/refrigeration chamber with grids (I.1), inlet- and outlet channels (I.3, I.4) for hot/cold flow and cooking/refrigeration space (I), with isolating inserts (I.3) separating off the chamber treatments.

Patent DE-19626305-A1 (DE)
Inventor: VOGEL GUENTHER
IPC: F15B1/033
Filed: 1996-07-01
Abstract: This invention proposes to provide a hydraulic brake system with a device for active braking with a diaphragm damper (8) which is optimally configured with regard to its overall dimensions. The diaphragm (9) of the diaphragm damper of the invention is not constructed in planar form, as is common in prior art, but in a pot shape. This simplifies installation in a valve block, which is difficult with a diaphragm damper (8) of great surface area, because the bores of such a valve block are located in close proximity to each other. The edge (11) of the diaphragm (9) of the diaphragm damper (8) can also serve as the housing gasket, so that any additional gasket is unnecessary. The diaphragm damper (8) can be advantageously placed in a location in which it replaces a bore seal otherwise required.

Patent DE-19636816-A1 (DE)
Title: Cable arrangement for motor vehicle electrics
Inventor: BUECHNER OLAF DIPL ING
IPC: H03H1/00
Filed: 1996-09-11
Abstract: The arrangement includes circuits placed at several points between the cabling and the metal vehicle body, to terminate the cables with at least approximately their characteristic high frequency (HF) impedances.  Reactive terminating resistances are weighted with real impedances, for HF matching to the reactive impedances, so that the real resistance has essentially the same value as the characteristic impedance in the HF noise region. A cable section is enclosed by a conducting sleeve whose characteristic impedance is terminated, so as to be matched to the metal vehicle body. Ferrite chokes in the cable loom, or individual cables, have a higher HF resistance than the characteristic impedance. Ferrite components in common lines for several terminals transform the line impedance approximately to the characteristic HF impedance.

Title: Central node converter for coupling to terminal of house network
Inventor: COUTINHO ROY S
IPC: H04H20/76
Filed: 1997-01-23
Abstract: The central node converter includes a filter (212) which removes frequency components below a prespecified minimum value, from external signals. The filter passes frequency components within a fixed band, to the output, to which is coupled an internal line (205). A modulator (222A) is coupled to the transmitter (206A), shifting the internal signal to one with frequency components such that the frequency cannot be received by the receiver (208A). A low pass filter (226A) passes the shifted signal to a block converter (210) for converting the signal into a frequency outside of the fixed band, but compatible with the receiver. An amplifier (214) treats the converted signal and externally transmitted data for reception.
Patent DE-19702417-A1 (DE)
Inventor: TORKLER HEINZ
IPC: B63B27/14
Filed: 1997-01-24
Abstract: To adjust the incline of a ramp and to create a bending-resistant connection for a ramp (3) pivotably connected to a bridge support (1), a differential cylinder (10) is mounted in the area of the pivot point (2). The piston surfaces of the differential cylinder (10) are impinged upon with pressure that is adjusted in accordance with the prevailing load (11). The pressure in the cylinder chamber (10s) on the side of the rod is a measure of the bending moment in the connecting area between the ramp (3) and bridge support (1). A pressure limiting valve (13) serving as safety valve limits the bending moment. The pressure limiting valve (13) is arranged inside a line (12) directly connecting the two cylinder chambers (10s, 10b) to each other. When the pressure limiting valve (13) is actuated, hydraulic fluid is displaced from the cylinder chamber (10s) facing the rod and fed to the cylinder chamber (10b) facing the floor. To the low-pressure side of the pressure limiting valve (13) is connected a volume control container (15) which equalizes the volume between the hydraulic fluid displaced from the cylinder chamber (10s) facing the rod and the hydraulic fluid needed by the cylinder chamber (10b) facing the floor, and which, when the load on the ramp (3) is reduced, absorbs from the cylinder chamber (10b) facing the floor hydraulic fluid not required by the cylinder chamber (10s) facing the rod.

IPC: H04B7/08
Filed: 1997-04-10
Abstract: The method involves selecting a signal for the radio receiver by switching-on one of several receiver aerials, with the selection based on the signal measured quality.  In addition the signal quality for a preset, future time interval is determined, according to the measured signal quality.  Preferably the signal quality is preset for a time interval smaller, with respect to a typical fading duration. The radio system signals are typically of the digital TDM type, formed from the pulse bundles of certain time intervals of sequential frames, divided in time intervals.  The signal quality of the bundle is measured.
