Patent DE-4244049-A1 (DE)
Title: Compensator for gas or water pipes
Inventor: RATTAY HANS
IPC: F16L27/04
Filed: 1992-12-25
Abstract: The compensating bellows (13) acting as an articulated compensator between the two pipe ends is enclosed by a cylindrical housing (8). It contains a further compensating bellows (14) designed as an axial compensator (12) and having a lower spring rate.The housing is divided into housing sections (15,17) which form safety chambers (16,18) covering the compensators (12,13).  The housing section (15) of reduced diameter which is directed to the pipe end (1) can be pushed over a force transmission ring (21) in the larger diameter housing section which covers the axial compensator and is supported by a housing guide (22) on the housing section (15) of smaller diameter.
Patent DE-4244721-A1 (DE)
Inventor: LUTZ DIETER DR ING
IPC: H02K9/00
Filed: 1992-05-25
Abstract: The proposal is for a fluid-cooled power transistor arrangement, the semiconductor component (1) of which is arranged on an especially boardlike insulating substrate (9) via a metal electrode (7). The flat side of the semiconductor component (1) away from the insulating substrate and/or the side of the insulating substrate away from the semiconductor component is in direct heat-exchange contact with a forced flow of cooling fluid in a channel (13). Here, the insulating substrate (9) or the semiconductor component (1) may form wall regions of the coolant channel (13). In order to improve the heat transfer, the wall regions to be cooled and in contact with the cooling fluid may have a surface microstructure which reduces the boundary layer thickness of the coolant flow. The improvement in the cooling action reduces the structural space required so that the electric valves may be fitted in the immediate vicinity of the electric device to be switched. This is of special advantage in electric motors in order to reduce line inductance. The electric motor and the electric valves are advantageously cooled by the same coolant circuit.

Title: Roller of a crushing device
Inventor: KLEIN REINER
IPC: A01D82/00
Filed: 1993-07-01
Abstract: Rollers (40) for crushing devices in forage harvesters have previously consisted of a one-piece jacket tube, in whose circumferential surface an edge profile is milled. The milling and subsequent hardening operation is difficult with the customary length of the rollers (40) and leads to distortion. A roller (40) is proposed, which is composed of a plurality of jacket parts (42) which follow on from one another in the axial direction. The short length of these jacket parts (42) allows processing on simple machine tools and allows the exchange of defective jacket parts (42). Rollers of this type are used in forage harvesters. <IMAGE>

IPC: H04L25/03
Filed: 1994-07-21
Abstract: A process is disclosed for detecting zero crossings of data signals by means of a comparator. In order to detect zero crossings in an accurate manner even when data signals (D) are distorted during transmission through a system with filtering characteristics, an auxiliary voltage (Uh) that corresponds to half the difference between the detected maximum and minimum values of the data signals (D) is generated. By comparing a reference value (Ub) proportional to the auxiliary voltage (Uh) with the momentary value of the data signal (D), an additional voltage (Uz) is formed to which the auxiliary voltage (Uh) is added to form a total voltage (Us). The total voltage (Us) is used to form the reference voltage (Uref5) of the comparator (5).
