Title: Method for operating a pulse-pattern generator
Inventor: PRENZEL WERNER DIPL ING
IPC: H02M7/527
Filed: 1985-11-09
Abstract: In the case of a method for operating a pulse-pattern generator (PMG) which controls the valves of a converter using the undershooting method and produces pulses by interface comparison of a sinusoidal voltage with a synchronised triangular-waveform voltage, it is intended to prevent discontinuities occurring in the fundamental of the output voltage at the converter when there are no interfaces to the triangular-waveform voltage at a relatively high drive level of the sinusoidal voltage. For this purpose, when a pulse must be produced on comparison of the sinusoidal voltage with the triangular-waveform voltage, which pulse is equal to or shorter than the minimum switching time to be maintained in the case of the valves, this pulse is marked out and its voltage/time integral is added to the remaining pulses. <IMAGE>

Title: Device for generating currents for electotherapeutic treatment
Inventor: STEFFEN HARTWIG DIPL ING
IPC: A61N1/32
Filed: 1985-11-21
Abstract: A device for generating currents for electotherapeutic treatment is described, in which the amplified output currents of two mutually detuned medium-frequency oscillators are introduced into a tissue on current paths which cross one another in a treatment zone, so that currents having a beat frequency are produced in the treatment zone. The aim with such a device is to exclude the influences of ageing, temperature and component tolerances. This is achieved by an automatic, periodic recalibration by means of a crystal oscillator (1) and a phase-locked loop. The phase-locked loop can be interrupted, the control voltage occurring in the phase-locked loop being stored by a sample-and-hold circuit (9), and applied to the oscillator (12). A voltage for detuning the oscillator (12) can then be superimposed via a control unit (18). A differential frequency control circuit (17, 16, 15, 14) controls the differential frequency via the control unit (18) and the superimposed voltage (U3). <IMAGE>

IPC: H04N1/48
Filed: 1985-12-04
Abstract: A colour image reader for inputting data via a colour image into an electronic file or the like for the electrical processing of image information is specified. The image is read photoelectrically in order to obtain a number of analogue colour component signals which are then subjected to analogue processing and are finally converted into digital signals. This results in fast accurate reading of colour images, in which dark currents have no effect in the digital reading, whilst retaining a simple design.

Title: Process for producing a welded joint between plastic pipes, means for carrying out this process and pipe joint
Inventor: MEYER HANS-H
IPC: B29C70/00
Filed: 1986-01-07
Abstract: A welded joint between two plastic pipes (15) made of polyethylene is produced by inserting, into that end of the plastic pipe (15) designed as a socket part, an electrical coil (20) whose individual conductors are embedded in the material of the plastic pipe in the direct vicinity of its inner surface. The ends of the mutually opposite plastic pipes, in particular the parts which can be plugged one into the other, are designed to be complementary to one another and conical. As mould for introducing the coil (20) into the socket part, a longitudinally slit and frustoconically designed coil form (19) is used, which is made of hard polyvinyl chloride and has to have a higher melting point than the polyethylene of the plastic pipe (15). Into this socket part provided with a coil (20), the spigot part of a plastic pipe is inserted, a weld being achieved along the entire lengths of the plastic pipes plugged one inside the other by subsequent connection of the terminals (22) of the coil (20) to an electrical energy source. In this welding process, a large surface-area, high mechanical strength, reliably sealing connection is thus produced between the end regions of two plastic pipes (15) made of the same material. <IMAGE>

Title: Method for installing a vehicle door
Inventor: KAETHNER HANS-JUERGEN
IPC: B62D65/06
Filed: 1986-03-22
Abstract: When completing a door shell, which can be pivoted about a vertical hinge axis and is already aligned, in a vehicle this shell tends to sag in the lock region owing to the dead weight which is then higher. In order to compensate for this sag it is proposed to use a two-stage hinge bolt (13), the thinner pin (13c) of which protrudes during the preassembly of the door with a defined play at one end into the hinge opening (11a) of the hinge leaf (11) on the door side while the hinge leaf (12) on the vehicle-body side is welded to the vehicle body. The hinge bolt (13) is then completely knocked in which results in a raising of the door (2) in the lock region which is cancelled by the subsequent completion of the door and the higher weight connected therewith. <IMAGE>

Title: Foil roller blind
Inventor: PAAR DIETER
IPC: E06B9/24
Filed: 1986-10-02
Abstract: The invention relates to a roller blind, the function and handling of which are identical to those of the conventional roller blind. The essential feature of the invention is the design of the roller shutter which, in this case, comprises a plurality of foils. In the let-down state, the foils are arranged at a distance from one another, with the result that air cushions are located therebetween. A plurality of air cushions separated by foils together produce the roller-blind thickness and heat insulation in the same way as in laminated glazing. In order to improve the heat insulation still further, the foils have, in the direction of the air layer, surfaces with a metallic lustre, e.g. aluminium foils. Consequently, the proportion of radiation in the heat through-passage is reduced to a minimum. The foils are held at uniform distances on the borders of the roller blind by guide rails. In the lower guide rail there are located, between the foils, holes through which the air for the air cushions can enter and escape. When the roller blind is let down, the holes are closed in order to eliminate any possible air circulation. The two outer foils, which constitute the bordering of the roller blind, are reinforced in order to offer better protection against weathering influences such as hail, wind and the like. If the roller blind is pulled up, with the result that the foils are rolled up in the roller-blind casing, then the air of the air cushions has flowed out through the holes in the lower guide rail, with the result that the ...

Patent DE-3701337-A1 (DE)
Title: Pluggable pinhole diaphragm for macrophotolenses of miniature reflex cameras (35mm), size 24mm x 36mm, for extending the depth of field
Inventor: KOPP ROBERT
IPC: G03B9/02
Filed: 1987-01-19
Abstract: Heretofore, pinhole diaphragms were used only in conjunction with an expensive, additional third-party lens focusing system ("adjusting worm") which does not belong to or fit the camera equipment, as well as adapters for extending the depth of field. These third-party adapter elements could not use the automatic exposure control of reflex cameras. The novel, cost-advantageous, pluggable pinhole diaphragm makes it possible to extend the depth of field of the macrolens(es) forming part of the camera in conjunction with unlimited use of the automatic exposure control of the camera, without adapter elements and adapters. As a result of the pluggable embodiment of the pinhole diaphragm (quick-change system), the full image brightness of the finder eyepiece of the camera is available for adjusting the sharpness of the foreground and for determining the image section with the pinhole diaphragm removed. The pinhole diaphragm (1; Fig. 1) has a self-clamping holding (2; Fig. 1) which is plugged onto the outer diameter of the thread mount of the lens. The outside of the pinhole diaphragm (3; Fig. 1) is seated directly on the surface of the front lens (6; Fig. 2) of the macrolens (5; Fig. 2-simplified illustration). The hole diameter of the pinhole diaphragm (4; Fig. 1 and 2) corresponds to the required aperture for extending the depth of field. <IMAGE>

Title: Therapeutic explosion-pressure surge device
Inventor: SCHUBERT WERNER DR MED
IPC: A61B90/00
Filed: 1987-02-11
Abstract: Explosion-pressure surges have already been employed for crushing concrements in the urether and in the bile ducts. It would represent a supplementation of other, already known physical therapies if metered doses of explosion-pressure surges could be used for the acute, high-energy therapy of, for example, tumours, that is to say malignant growths, such as cancer of the mammary glands which is still difficult to treat. This requires suitable carriers as instruments in order to deposit the explosive substance required for generation of the pressure surge in the tissue in the region of the focus and detonate it at the correct site for a therapeutic effect.

Inventor: DAPPERHELD STEFFEN DR
IPC: C25B3/25
Filed: 1987-02-17
Abstract: The existing processes for the preparation of halogenoacrylic acids and deuterated derivatives thereof have to be carried out using chemicals which are in some cases very toxic or very expensive. Electrochemical reduction, however, makes it possible to eliminate one or more halogen atoms selectively from halogenoacrylic and halogenomethacrylic acids and derivatives thereof, and to replace these by hydrogen or deuterium atoms. This is effected by electrolyzing the acids or derivatives thereof in a solution containing water or deuterium oxide at a temperature from -10 DEG  C. up to the boiling point of the electrolysis liquid.

Title: Biofeedback insole
Inventor: ROBBINS STEVEN E
IPC: A61F13/06
Filed: 1987-07-16
Abstract: The sole of the human foot possesses many mechanoreceptors and nerve receptors which supply information to the nervous system to respond with the appropriate behaviour in order to protect in particular the lower extremities against injuries. The currently available insoles with irregular surfaces are intended to cause pleasant sensations by massage or the like. The insole remains uniformly compressed when loaded. In order to reduce the risk of injuries by overstraining the sole of the foot on excessive loading, a multiplicity of local foot sole deformations is generated. The biofeedback insole is for this purpose subdivided by a foam-like plastic into regions 38 in which particles 40 are displaced with every step. The stimulation of the sole of the foot produced by their distribution each time can elicit protective behavioural reactions. The biofeedback insole is preferably suitable for use in sports shoes. <IMAGE>
