Title: Layered material or layered workpiece and process for the production thereof
Inventor: HODES ERICH DIPL CHEM DR
IPC: C23C14/32
Filed: 1987-02-12
Abstract: An improved layered material or layered workpiece, in particular for the production of slide elements or frictional elements, can be produced by applying the functional layer by means of ion plating, the functional layer being built up from particles of a vapour phase and/or microparticle phase and said particles being accelerated to such a high kinetic energy by means of an electrical gas discharge or by means of an ion beam that, when they impinge on the substrate surface or the continuously forming functional layer surface, they cause intense movements in the particles present there and as a result influence the adhesion strength and the structure of the layer forming. This results in the tight packing together of the forming layer up to the density of a corresponding solid material and a diffusion-like incorporation of material particles into the substrate surface and transfer of substrate particles into the lowermost region of the functional layer.

Title: Reference electrode for ion-activity measurement, in particular for pH measurement
Inventor: RUSSEL THIMOTY H
IPC: G01N27/30
Filed: 1987-02-14
Abstract: A reference electrode, in particular for a pH-measuring cell, for connecting to an electrical instrument with a measuring amplifier inserted in between, an additional measuring electrode being connected to the measuring amplifier. Known electrodes of this type are usually sensitive to contaminants and not resistant to elevated temperatures and pressures or to acidic and alkaline solutions. In the case of the reference electrode according to the invention, resistance to high pressure and high temperatures and to the abovementioned solutions is achieved by providing a glass tube whose lower end is sealed by a stopper composed of porous ceramic. The glass tube is filled with an electrolyte and contains a chlorinated silver wire which is immersed in the electrolyte and connected to a connecting cable. The glass tube is surrounded by a sheath composed of a conducting plastic. The material proposed for the sheath is a cured vinyl ester or polyethylene saturated with crystalline potassium chloride, polyvinyl chloride or epoxy resin, a conducting additive being added in each case.
Patent DE-3721693-A1 (DE)
Title: Electrohydraulic actuator
Inventor: WILLENBROCK WALTER
IPC: F15B9/12
Filed: 1987-07-01
Abstract: The electrohydraulic actuator has a valve device (16) with which a hydraulic motor (30) can be reversed. The valve device (16) is moved by a control part (15) which is a component of a compensation mechanism (14). A displacement movement preset by a stepping motor (10) is imparted to the presetting part (13) which adjusts the control part (15). The output of the hydraulic motor (30) is coupled to an answer part (28) which cancels the adjustment of the control part (15) as soon as the desired position is reached. An actuator of this type has the disadvantage that, if the hydraulic supply fails or is cut off, an adjusting command not yet performed remains stored by the position of the control part (15) and is still performed after the hydraulic system is switched on again. To achieve a defined initial position when the hydraulic system is switched on, the control part (15) is coupled to a sensor device (35) which controls the stepping motor (10) in a preparation phase via a microprocessor (11) in such a way that the control part (15) is put into the neutral position. The sensor device (35) also performs the function of the limit switches. Its sensors are checked for serviceability in the preparation phase. <IMAGE>

Patent DE-3730768-A1 (DE)
Title: Packaging container, in particular for receiving bars of chocolate
Inventor: SCHULZ JOERG-PETER DIPL ING
IPC: B65D5/00
Filed: 1987-09-12
Abstract: The packaging containers used previously for packaging bars of chocolate have the disadvantage that packaging the same number of bars of different thickness requires either packaging containers of different dimensions or additional packaging elements for filling in hollow spaces. Additionally, the secure stacking of such packaging containers often poses difficulties. The novel packaging container is to be dimensionally stable, stackable and, with a manner of production which is simple and uses little material, provide the possibility of adapting the usable depth of the container interior without the use of additional packaging elements. In order to increase the dimensional stability of such a packaging container, corner flaps (30) are arranged in the corner regions of the bottom part (10) of the packaging container in addition to the inner flaps (24) bonded on the inside, which corner flaps allow externally overlapping bonding of the front wall (15) or the rear wall (14) to the side walls (13). The angular projections in the corner regions of the bottom part which protrude beyond the plane of the lid part (11) provide a partial positive-locking engagement of the packaging containers stacked one above the other and thus reliable stacking. Arranged on the rear wall (14) of the packaging container are variable spacers (36) which are part of the blank (20) of the bottom part (10). Packaging of individual articles. <IMAGE>

Patent DE-3838133-A1 (DE)
Title: Gear machine (pump or motor)
Inventor: NONNENMACHER GERHARD DIPL ING
IPC: F04C2/08
Filed: 1988-11-10
Abstract: The gear machine (pump or motor) has two gears (14, 15) which mesh with outer engagement and against the lateral surfaces of which sealing plates (19, 20) are pressed in order to keep the leakage losses between the high-pressure and the lower-pressure side low. the sealing plates have bores (21, 22) through which the shaft journals of the gears penetrate. In order to ensure the tightness along the sealing plates in the case of gears having large tooth heights and a relatively small root diameter, the bores (21, 22) are offset eccentrically towards the low-pressure side. By this means, a sufficiently large sealing region remains on the high-pressure side despite the small root diameter. <IMAGE>

Title: Electric fence device
Inventor: WEINREICH WILHELM DIPL ING
IPC: H05C1/04
Filed: 1989-02-18
Abstract: An electric fence device 20 contains two complete capacitor discharge circuits A and B, each to be closed and opened independently, each of which is formed with at least one individual energy storage capacitor C1 or C2, respectively, and a primary winding W11 or W12, respectively, of a common pulse transformer (converter) Tr or two pulse transformers Tr1 and Tr2. Each of these discharge circuits A and B contains its own electrical switch S1 and S2 which can temporally control the current transmission state. For these two electrical switches S1 and S2, a common pulse timer provided for them, having two outputs a and b, is controlled by means of a mode control unit 34 in such a way that, during normal or wet weather or ground conditions, pulse trigger signals appear only on the output a, so that, in such circumstances, the pulse generator is operated only with the one discharge circuit A. Provision may furthermore be made for pulse trigger signals to appear on the one output a of the pulse timer T in the usual time frequency of, for example, 1s, whereas an additional pulse trigger signal appears on the second output b as a second pulse trigger signal only at every nth trigger signal of the output a, the temporal arrangement of which second pulse trigger signal with respect to the first pulse trigger signal appearing on the output a being fixed in the pulse timer T or adjustable on the pulse timer T. <IMAGE>

Title: Method for producing or inspecting microstructures on large-area substrates
Inventor: WIJNAENDTS-VAN-RESANDT ROLOEF
IPC: G02F1/13
Filed: 1989-03-28
Abstract: The invention relates to a method for producing microstructures on large-area substrates, in particular liquid-crystal displays, structures at least of one mask being transferred by optical means onto a substrate. These optical means contain lens and/or mirror systems which become large and unwieldy as the size of the display increases, and require considerable outlay in terms of construction. It is based on the object of proposing a method, by means of which large-area displays which have edges of at least 10 cm length, can be produced in a reliable manner even in large numbers. It is proposed that the structures are continuously scanned from the mask in small areas and transferred onto the substrate by means of an optical transfer system. The transfer system and the mask as well as the substrate can be positioned with respect to each other. <IMAGE>

Patent DE-3917247-A1 (DE)
Inventor: SAWAGATA KIYOSHI
IPC: H04N5/7826
Filed: 1989-05-26
Abstract: A video signal reproducing apparatus in a system for fast locking a reproduced image obtained from a recording medium where a time code signal is recorded for each video signal frame, the apparatus including memory means 14 for storing plural frames of the video signal, a time code comparator 12 for generating a control signal SDF by comparing the time code signal obtained from the recording medium with an external reference time code signal E.TM, and a reading controller 15 for controlling the memory means 14 and selectively reading one frame of the video signal therefrom in accordance with the control signal SDF so that the time code signal corresponding to the video signal selectively read by the reading controller 15 coincides with the reference time code signal E.TM. The video signal reproduced by the apparatus placed in a standby state upstream of an edit point can be raised to a stable normal reproduction state within a relatively short time. The video signals retained in synchronism are sequentially stored in frame memories 14-1 to 14-i of the memory means 14 and, after being delayed per frame, the video signal coincident with the reference time code signal E.TM is selected, whereby the lock-in operation can be completed rapidly thereby reducing the amount of preroll of the medium necessary to achieve full speed at the edit point. <IMAGE>
