Title: Determining the centre of radar targets
Inventor: MUELLER MANFRED ING GRAD
IPC: G01S7/292
Filed: 1981-03-11
Abstract: To determine the centre of distributed radar targets in real time, target messages newly arriving between the detection of target start and target end of a target, together with target messages already present, are investigated for their association with the same distributor target and, if so, the current target position data are compared with earlier stored position data. The maximum and minimum position data in range and azimuth direction, resulting from this comparison, are stored and used for determining the centre of the distributed target by arithmetic averaging after the detection of the target end. Both the position data of all hit messages and the part-targets determined in accordance with the moving-gate or signal-maximum detection method can be used for the comparison of position data. A combination of the moving-gate target detection method and the signal-maximum detection method is found to be particularly advantageous.

Title: Process and apparatus for producing multi-colour designs or decorations on textile fabric
Inventor: SCHOLZ HARTMUT
IPC: D06B11/00
Filed: 1981-04-24
Abstract: The invention relates to a process for producing multi-colour designs or decorations on single-colour textile fabric. In a known handicraft method, coloured yarn corresponding to the particular design is looped onto a prepared semi-finished woven fabric (canvas) via individual weaves of the fabric by means of an appropriate needle. For this purpose, the appropriate quantity of correspondingly coloured yarn pieces of appropriate length must be added to the canvas. The materials required for carrying out the known process are costly and the work is highly time-consuming. According to the invention, the new process provides the user with a fabric having knobs, a single-colour yarn being used and the surface features of this fabric corresponding to those of a ready hand-embroidered canvas. The fabric knobs analogous to a master are loaded individually in succession with a selected dye. In the process according to the invention, no coloured yarns are required, on the contrary the single-colour yarn of the initial material is coloured with a textile dye at the appropriate points in spots or in delimited regions. Preferably, the individual knobs are provided with the respective associated dye by means of a stamping apparatus, that is to say the yarn is saturated with the dye at the corresponding point. The invention also embraces apparatuses (stamping apparatuses) for applying the textile dye to the selected knobs.

Title: Pressure-decrease valve and its use on a gas piston compressor
Inventor: WANNER HANS
IPC: F16K17/02
Filed: 1981-05-08
Abstract: A pressure-decrease valve has, as actuating member, a diaphragm (8) which is connected to an approximately cylindrical valve tappet (10). In the event of subatmospheric pressure in a line (24) on the subatmospheric-pressure side (11), the end side (20) of the valve tappet is pressed against the valve seat (9). The connection between subatmospheric-pressure side (11) and diaphragm (8) is produced via a bore (17) starting from the end side. A particularly advantageous use of the pressure-decrease valve is obtained with gas piston compressors which exhibit a fluid circuit for sealing off and cooling the sealing portion on the drive shaft. The pressure-decrease valve prevents fluid from being able to pass into the compressor housing via a pressure-compensation line in the event of a subatmospheric pressure arising in said compressor housing. <IMAGE>

Title: Measuring diaphragm for countering diffusion of pressure media
Inventor: NEUBECK KURT DIPL PHYS DR
IPC: G01L7/08
Filed: 1981-06-02
Abstract: A measuring diaphragm for pressure and differential pressure measuring arrangements for use with pressure media which can diffuse through metallic diaphragms consists of an accommodating member (2) for the measuring diaphragm which has a turned diaphragm bed (3) in a concentric, sinusoidal corrugation, and two metal diaphragms (4, 7) between which a filter diaphragm (6) is located. A pressure medium diffusing through the first metal diaphragm (7) can pass radially outwards through the filter diaphragm (6) into a ventilation groove (5) and from there to the external atmosphere via a ventilation bore (10). The pressure medium is prevented from pressing further forwards into the second metal diaphragm (4), which separates off the liquid (15) of the pressure medium. Consequent damage to the overall measuring arrangement cannot therefore occur. <IMAGE>

Title: Device for covering to provide protection against electric shocks and for the insertion and withdrawal of fuse cartridges
Inventor: LANGMATZ HANS
IPC: H01H85/02
Filed: 1981-07-08
Abstract: A device for covering to provide protection against electric shocks and for the insertion and withdrawal of low-voltage, high-power fuse cartridges (NH fuse cartridges) into and respectively out of their contact terminals has a covering cap which surrounds the fuse cartridge at the top and on the sides, with a handle which can pivot, on whose underneath pins (pegs) are provided which project into curved grooves on sliding elements which can be displaced in box-shaped depressions. The grooves in the sliding elements are preferably constructed such that the pivoting of the handle from the vertical in one direction causes the sliding elements to be displaced, but in the other direction remains ineffective. Pins which project from the lower surface of the sliding elements engage in holes in bars, so that these bars are displaced together with the sliding elements, guide bolts which project from the lower surface of the bars engaging in guide grooves which are located in the base surface of the box-shaped depressions and, in conjunction with the displacement movement caused by the sliding elements, making the bolts open and close like pliers around tongues of the fuse cartridges. The handle can be protected against inadvertent pivoting by means of a block and slots into which projections engage, for which purpose lower parts can be guided in the hollow limbs in the upper part of the handle and can be displaced against the influence of springs.

Patent DE-3130360-A1 (DE)
Inventor: HUSSMANN PETER DR
IPC: B01D29/00
Filed: 1981-07-31
Abstract: According to the method for extracting substances, particularly from aroma rich materials, a plurality of amounts of removal solvents of different concentrations are mixed successively step by step, at each cycle, with the very finely ground extraction substance, which is renewed after each cycle. The method starts with the solvent having the highest concentration (I) and ends with the solvent having the lowest concentration (XIII). After the formation of each mixture (2), a solvent enriched with extracts is again (3) separated from the mixture, the solvent having the highest concentration (0) being discharged and replaced by fresh solvent, and the other separated solvents are stored for the following cycle. With each cycle, the extraction substance is mixed(5, 6) at least once and intensively with an amount of solvent, said mixture being obtained in an intensive agitator or in a ball-mill, thereby increasing the yield. The temperature of the method corresponds to room temperature and the device for implementing such method comprises an extractor having a flat filter bed (2) wherein there is provided a device for cleaning the filtering material (3). The cleaning device comprises, below the filtering material, a rotary nozzle wherefrom a high pressure purifying product is ejected and traverses the filtering material from bottom to top. By cleaning the filtering material, an increase in the separation rate in the extractor is obtained.

Title: PCM device
Inventor: KELLNER BERND
IPC: F28D20/02
Filed: 1981-08-18
Abstract: The PCM device, in which the transfer of heat into and from the PCM storage medium (4) is performed via oil droplets which emerge from nozzles (10) in the lower region of the PCM storage medium, has a porous coating, preferably as a part (12) made from foam (expanded, cellular plastic), for the exit nozzles, which prevents the nozzles from being stopped up by solid PCM storage medium. The oil droplets obtain their heat, which is to be dissipated to the PCM storage medium, from worm(screw)-type heat exchangers (6) arranged in horizontal layers, and the outward dissipation of the heat absorbed by the oil droplets from the PCM storage medium is likewise performed via such worm-type heat exchangers (6, 7), which simultaneously form a support grid for PCM storage medium crystallising out. <IMAGE>
Patent DE-3133175-A1 (DE)
Title: Phase locked loop
Inventor: VERHOFSTAD FRANK
IPC: G11B20/14
Filed: 1981-08-21
Abstract: The phase locked loop serves to synchronise input signals (E) with reference signals (B) which are obtained from clock pulses (TA) with a variable repetition frequency which are generated in a clock generator (TG). The input signals (E) and the clock pulses (TA) are fed, with the intermediate connection of frequency dividers (Z1, Z2), to a phase detector (PD) which generates control signals (ST) via a filter (F) for the clock generator (TG) with which the repetition frequency of the clock pulses (TA) is modified. A switching stage (SS) disposed between the frequency dividers (Z1, Z2) and the phase detector (PD) ensures reliable phase-locking of the loop even when the repetition frequency of the clock pulses (TA) exceeds an upper limit. The switching stage (SS) checks the pulse period of signals allocated to the input signals (E) and extends them to a pre-defined value if required. <IMAGE>

Title: Device for the correction of stuffing (padding) errors in a digital signal multiplex apparatus
Inventor: POSPISCHIL REGINHARD DR ING
IPC: H04J3/07
Filed: 1981-09-15
Abstract: Such a device has a clock matching element in the receiving section behind each demultiplexer output. This clock matching element contains a buffer store (2) in the transmission path of the useful signal, and a phase discriminator (3) is located between its read-in clock input and its read-out clock input and controls an oscillator (5), which can track, for producing the read-out clock. According to the invention, a monitoring device (6) is connected downstream of the buffer store (2) in order to ensure occurrence at the correct time or displacement by + one bit of the frame tag word of the subsystem. In the case of both such displacements, the monitoring device (6) emits a correction signal to the buffer store (2), which correction signal causes the buffer store (2) to carry out clock matching. A bit slippage caused by brush noise (disturbances, interference) or brief interruptions is in this way eliminated as early as the next frame and has no influence on subsequent demultiplexing. <IMAGE>
