Filed: 1988-04-08
Abstract: In a pressure-reducing arrangement with a pressure-reducing valve (16) and a pressure-indicating device (18) for indicating the outlet pressure, the pressure-indicating device (18) contains a spring-loaded piston (156) acted upon by the outlet pressure of the pressure-reducing arrangement, an indicating member (166) rotatable about the axis of the piston (156), and a coarse-threaded guide (172, 174) by means of which a linear motion of the piston (156) can be converted into a rotary motion of the indicating member (166). The indicating member (166) is a rotatably mounted disc (168) with a central shaft (170). The pressure-reducing arrangement contains a pipe connection piece (10). On one side, the pipe connection piece (10) has a collar (54) into which is inserted a filter cup (12), a collar (62) which is coaxial with the collar (54) and which holds a screen (14) centred, and an opening (68), which is arranged coaxially within the collar (62) and is connected to the outlet connection piece (22). The pressure-reducing valve (16) is arranged coaxially within the screen or filter (14) and its valve-seat body (70) is held in sealing fashion in the opening (68) of the pipe connection piece (10). A cylinder (150), in which the piston (156) of the pressure-indicating device (18) is guided, is formed integrally on the pipe connection piece (10). <IMAGE>

Title: Method and arrangement for determining the blood group
Inventor: HOEKSTEIN KLAAS NUTTERT DIPL I
IPC: G01N33/487
Filed: 1988-04-21
Abstract: To determine the blood group of a blood sample with the aid of an antigen-antibody reaction leading to haemagglutination, the blood sample is mixed with the specific antiserum, and the change  DELTA Z in the impedance of the blood sample mixed with the antiserum is measured within a preset time interval T. The change in impedance is compared with a limit and is a criterion for a positive reaction when it is larger than the limit and is a criterion for a negative reaction when it is smaller than the limit. <IMAGE>

Patent DE-3823018-A1 (DE)
Inventor: SCHLEUPEN RICHARD DIPL ING
IPC: H04B15/04
Filed: 1988-07-07
Abstract: A process and device for suppressing interferences by microprocessor circuits reduce the amplitude of the interference signals emitted by the processor circuit. When such microprocessor circuits are used in motor vehicles, radio reception is affected by interference signals from the microprocessor circuit. For example, the PLL stops during automatic tuning of transmitting stations at frequencies where there are no radio stations. According to the invention, disturbances are avoided by subjecting the oscillator frequency of the processor circuit to frequency-modulation. For that purpose, the oscillator (2) of a voltage control circuit (C, R) is tuned off by an associated variable capacitance diode (3). The frequency of the oscillator (2) decreases as the capacitance of the variable capacitance diode increases, and the capacitance of the diode changes with the output signal of the voltage control circuit: it increases as the voltage of the control signal decreases. In this way, the interference signal level is efficiently reduced without the need for arranging the processor circuit within a shielded housing.

Title: Method and device for the contactless determination of the cross-sectional dimensions of elongated objects
Inventor: MOND MATHIAS DIPL ING
IPC: G01B11/245
Filed: 1988-08-29
Abstract: In a method for the contactless determination of the cross-sectional dimensions of elongated objects moving in their longitudinal direction and having an at least approximately convexly rounded cross-section, optical scanning devices which detect said cross-section and are arranged round the track of travel of the object are used to measure the position of the edges of the object which are visible to the respective scanning device, and from this the cross-sectional values are calculated by means of an evaluation device. In order to be able to eliminate discontinuities in the variation in the profile between successive measurements in the case of objects of irregular cross-section, area-measuring scanning devices are used respectively to detect length sections of the object which overlap in the longitudinal direction. By comparing successive measurements in the overlap region, it is possible to eliminate discontinuities caused by the shaking (rocking) of an object, and to determine the exact variation in the profile of the object.

Title: Schmitt trigger for binary count values
Inventor: STEINBACH GEORG DIPL ING
IPC: G06F7/02
Filed: 1989-03-17
Abstract: The intention is to give a circuit arrangement for a Schmitt trigger, which compares time-dependent binary count values to several constants. A digital memory (Sp), to the address lines of which (A0, A1, ... Ak, Ak+1) the binary count value is serially applied, is used for this purpose. The data output (Q) of the memory (Sp) is fed back to the highest value address line (Ak). The memory bits of the memory (Sp) are set to "0" in the least significant half, from the least significant address (A0) to a set point (S), in the direction of ascending significance of the address lines (A0, A1, ... Ak, Ak+1), corresponding to a specified constant, and then to "1" to the end of the least significant half. The memory bits of the most significant half are also set to "0", to a reset point (nR), corresponding to another specified constant, and then to "1" to the end of the more significant half. <IMAGE>

Title: Three-part, foldable shower-partition door
Inventor: DUDEK GABRIELE
IPC: A47K3/36
Filed: 1989-04-01
Abstract: Three-part folding doors have until now always projected by about one third of their total width into the shower area, which often led to collisions with fittings and practical usage was thus not guaranteed.   In the case of the door described hereinbelow, despite the division into three parts, only about one quarter of the door width projects into the shower area, which has the result that the abovementioned problem is hardly likely to occur. In addition, the usability of a pivotable mirror and the good cleaning possibility from outside afford interesting advantages.

Patent DE-3918235-A1 (DE)
Title: Transfer line system for machining and forming - has long operation stations offset from main transfer line with to=and=fro transfer of work
IPC: B23Q7/14
Filed: 1989-06-05
Abstract: Transfer line systems have a cycle time governed by the time required for the longest operations. Usually the transfer line is divided at long operations so that two or more identical machines can work onn alternate workpieces and thus enable the desired line cycle time to be maintained. Waste of space is avoided in the new system by having the two identical stations (24,2B) for the long operation offset in a plane (A') parallel to the principal transfer plane (A).  Workpieces are picked off the transfer line (A) into the  plane (A') by suitable gripped arms, machined, and then returned to the transfer line (A) for the remaining operations. The system can be designed for linear or circular transfer systems. USE/ADVANTAGE - Transfer line with reduced space and better control over work flow.

Title: Spinning spindle - has the sleeve in the spindle base suspended from a spring bracket
Inventor: FORTKORT BERNHARD ING GRAD
IPC: D01H7/04
Filed: 1990-02-27
Abstract: Sleeve on the interior of a fixed spinning spindle housing is suspended from a spring bracket, and supported by a base spring in the housing. Connection between the neck and base bearing is rigid, and extends to the whorl beneath the spring bracket. The whorl is smaller in dia. than the neck bearing. Point (10) of a spinning spindle (1) pref. protrudes through the ring (11). Spindle rail (6) is pref. rigid, with the housing (13), and this extends to a spring clip (8) held at the top by screws (14,15) to the interior sleeve (4,5,12). This is further supported by a spring arrangement (7) under the base bearing (2).  Neck bearing (3) is pref. rigidly sepd., and surrounded by a suppression spring. Whorl (9) on the spindle shaft, is above the neck bearing, and is of smaller dia..  Spring clip (8) is adjustable in position, and then locked by the screws (15) in order to centre the spindle. ADVANTAGE - Spring suspension, with a suppression arrangement in the spindle base, eradicates spindle tilt, with corresp. redn. in wear of the ring and traveller. Small whorl gives high speed with lower belt speed. Variation in speed has no effect on the central position of the spindle.
