Patent DE-3732543-A1 (DE)
Title: Shift register basic adder circuit
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1987-09-26
Abstract: The shift register basic adder circuit according to the subject of the invention is a special shift register adder circuit, the main circuit of which consists only of simple flipflops, which are triggered by such short clock pulses that the content of the flipflops is displaced further to the right by only one flipflop at each cycle. The pattern circuit which is shown can add, at maximum, only the number 4 to the number 4. In the normal case (when there is a summand at the A inputs and the B inputs), circuit (80) is effective, so that the flipflops which are triggered with high potential form a closed column. The addition is complete when the negating circuit (29) has low potential at its output. <IMAGE>
Patent DE-3732997-A1 (DE)
Inventor: KURZ ARTHUR
IPC: H03F1/30
Filed: 1987-09-30
Abstract: Apparatus for the reproduction of data which can be read contactlessly from a recording medium by means of an optical scanning device. Such apparatuses are equipped with a focus control circuit, in order to focus the light beam scanning the data onto the recording medium, and with a track control circuit, in order to be able to guide the light beam on the data tracks. However, the control amplifier (FR) of the focus control circuit is affected by an off-set voltage, which varies with the temperature and ageing of the control amplifier. In order to compensate automatically for the off-set voltage of the control amplifier (FR) of the focus control circuit, an input of the control amplifier (FR) is fed an off-set compensation voltage, which is varied until the high-frequency components of the focus error signal (FE) assume a minimum, since in this case the off-set voltage is optimally compensated. CD players, video-disc players, draw-disc players, magneto-optical equipment. <IMAGE>

Patent DE-3743717-A1 (DE)
Title: Optoelectronic measuring apparatus for the automatic measurement of the position of the tool cutting edge using commercially available tool-presetting equipment
Inventor: SPITZLEY ALFRED DIPL ING
IPC: G05B19/401
Filed: 1987-12-23
Abstract: The invention relates to an "optoelectronic measuring device" for the fully automatic determination of edge position, for use in all types of commercially available presetting equipment in which the position of the tool cutting edge is measured with respect to a fixedly defined point by touching using mechanical sensors or by optical means, and for use in CNC machine tools and manufacturing centres. To measure the exact cutting edge position, an electronic measuring camera (1) takes a picture of the cutting edge. The imaging of the edge is effected by a high-quality measuring objective (2) of fixed focal distance and invariant imaging behaviour. An image processing system (3) stores the image data of this edge image digitally. At the same time, these data are displayed true-to-side on a video monitor (4). The computer in the image processing system then evaluates the image data with respect to the edge information and computes the exact position of the cutting edge in the image field. The local coordinates of the edge position are then normalised in relation to a defined fixed point in the image field, and differential values are determined. The measuring electronics of the tool-presetting equipment receives these data and uses them to compute the absolute position coordinates, which are used for tool presetting. <IMAGE>

Patent DE-3830943-A1 (DE)
Title: Arrow for sport, and a safety arrow for play
Inventor: BRUNSCH KURT
IPC: F42B6/04
Filed: 1988-09-12
Abstract: The arrow, as a weapon and sporting appliance has scarcely changed over the centuries. This fact appears to show that no basic improvement appears possible. If, however, the solid shaft is replaced by a cylindrical tube whose hole is expanded in the form of a nozzle at its end, that it is possible to dispense with guide surfaces of any shape if the incident-flow cross-section of the annular profiled tab is smaller than the outlet cross-section of the nozzle opening. This is because the air in the nozzle part is accelerated by expansion, as a result of which a reduced pressure is produced with respect to the ambient pressure, which exerts a stabilising effect on the shaft end. In order to make archery safer for young people as well, an elastic profiled ring is mounted at the front by means of struts instead of an arrow head, which profiled ring has a soft profiled nose, as a result of which the risk of injury is greatly reduced. Longitudinal rolled-out regions produce guide surfaces at the shaft end, two opposite surfaces being transformed into a grooved gripping plate in that the other guide surfaces are cut out from the end. The end of the gripping plate is thus provided with a notch, running on the longitudinal side, for the cord.
Patent DE-3833833-A1 (DE)
Title: Pump
Inventor: MATELA KAREL
IPC: F04B43/14
Filed: 1988-10-05
Abstract: The pump is equipped with a diaphragm (1) arranged inside a housing (2). Lamellae, for example comprising expandable rings (30), which are actuable transversely to the pump delivery direction and are arranged axially successively inside the diaphragm (1) deform the latter progressively in the manner of a wave. During this process, peristaltic annular delivery chambers (5) progressing from a pump inlet side to a pump discharge side are formed between one side of the diaphragm (1) and one inner side of the housing (2). These chambers are tightly closed by transverse wave crests (6) of the diaphragm (1), in that the respectively expanded rings (30) press corresponding parts of the diaphragm (1) tightly against the inner wall of the housing (2). The delivery chambers (5) can thus be closed more tightly in contrast to those inside a hose of a conventional peristaltic pump, the delivery chambers of which are to be sealed off merely by linear closures, since the closures have the form of circular transverse waves, with the result that a considerably higher underpressure can be obtained with a pump of this type. <IMAGE>

Title: Process and apparatus for loosening dust and dirt particles in filter units
Inventor: SINAMBARI GHOLAM-REZA DR ING
IPC: B01D46/00
Filed: 1988-11-04
Abstract: To detach dust or dirt particles it is proposed that the filter elements of a filter unit are excited to vibrate with the aid of a controllable vibrator built into the filter unit. The excitation frequency used is the natural frequency of the filter elements which is matched to the type and size of the dust or dirt particles to be separated off. The vibrations of the filter elements are measured and evaluated and rated with the aid of an analysis and control unit and used for open- and closed-loop control of the vibrator. As a result it is possible to change the amplitude and frequency of the vibrations of the filter elements in such a way that an optimal separation is achieved. The specific excitation of the filter elements makes it possible for a relatively high degree of separation to be achieved by a low expenditure of energy. Since measures are taken to avoid exciting other components of the filter unit to vibrate, and owing to specific decoupling of vibrations of the filter elements, noise pollution of the filter unit is also considerably decreased.

Title: Short vertical antenna having a maximised radiating area
Inventor: HILLE KARL H
IPC: H01Q9/36
Filed: 1988-11-28
Abstract: Vertical antennas with or without an electrical extension at the upper end are used for omnidirectional radiation in radio-frequency technology. A vertical antenna with a height of 0.64 wavelengths provides a maximum field strength in the horizontal direction. By using an extension according to the invention (which is folded twice and is essentially non-radiating as a result of compensation of opposing currents) on the head of the antenna, this short vertical antenna produces virtually the same field strength in the horizontal direction as the antenna having a height of 0.64 wavelengths, but is only 0.39 wavelengths high, which means a considerable saving in structural height and structural costs. <IMAGE>

Title: Silicon semiconductor component
Inventor: BENEKING HEINZ PROF DR RER NAT
IPC: H01L23/532
Filed: 1989-03-13
Abstract: In order to reduce the contact resistance, there is arranged, in semiconductor components, between the semiconductor layer to be made contact with, and the contact metallisation of the component, an additional contacting layer made of a material which has a lower energy gap, but a lattice constant which is virtually identical to that of the semiconductor layer to be made contact with. For silicon semiconductor components provision is made, according to the invention, for the contacting layer to consist of germanium and to be arranged in a hole in the insulating layer which covers the surface of the semiconductor layer to be made contact with. The contacting layer composed of germanium is deposited (laid down) in the process by means of the low-pressure vapour phase epitaxy process (low-pressure chemical vapour deposition = LPCVD) selectively in the holes of the insulating layer, without the insulating layer itself being covered.
Patent DE-3910366-A1 (DE)
Title: Apparatus for microbial reduction in swimming pools by means of ultraviolet rays incorporating a part-stream with an added disinfectant, such as chlorine
Inventor: UEBERALL PETER
IPC: C02F1/32
Filed: 1989-03-31
Abstract: Apparatus for the disinfection of swimming pools by means of ultraviolet rays including a chlorinated part-stream, which part-stream is only introduced into stagnant pool zones in which experience has shown there is no regular periodic exchange of water via the swimming pool filters within the calculated circulation time.   The invention indicates a way to very considerably decrease the use of chlorine in swimming pools as a result of which the known risks and pollution associated with chlorine are avoided. Since this is only possible with chemical-free sterilisation methods, the reduction of the chlorine can only be economically achieved via an ultraviolet sterilising apparatus. UV rays sterilise directly without further subsequent action in the water. Therefore, when they are used, on each purification circulation all of the water must actually be included which is not hydraulically possible. The invention indicates another way for the reliable use of UV sterilisation in swimming pools and thus avoids this difficulty. According to the teaching of the invention, up to 90% of the active chlorine used in swimming pools in a conventional manner can be dispensed with. The known annoyances such as chlorine odour and reddening of the eyes are also avoided. In addition, the risks due to transport, storage and use of this commercial poison are substantially eliminated and less chlorine passes into the environment.
