Title: PCM time multiplex data transmission system - uses synchronisation system with shift register and equaliser with AND=gates and OR=gate
Inventor: ZEMANEK JOSEF DIPL ING
IPC: H04L7/08
Filed: 1979-05-22
Abstract: The synchronising system between transmitting and receiving positions in a P.C.M. time multiplex data transmission system uses a signal block consisting of a two-bit synchronising word, a six-bit signal word and two signal words consisting of eight bits. The first bit of the two-bit word has more than two transmission periods for its binary value. The second bit alters after a number of transmission periods. A receiving shift register equalises the number of bits inside a block. An equalisier, after one or more transmission stages equalises the content of a selected bit stage with a bit memory and relates ti to further bit stage, and passes the output to an AND-gate system followed by an OR gate.

Title: Monomode multicore optical fibre-cable - has core spacing and cladding dimensions designed to give two propagation wavelengths
Inventor: HUBER HANS-PETER DIPL PHYS
IPC: G02B6/10
Filed: 1979-07-28
Abstract: Monomode multicore optical fibre has two transmission cores of higher refractive index contained in one cladding of lower refractive index. The differences between the refractive indices of core and cladding and the dimensions and spacings are chosen so that above a certain cut-off wavelength only two orthogonal propagation modes are possible. The modes are of different propagation speeds and there is no cross-coupling between them so if one is used in a fibre the other is prohibited. The multicore design enables one mode in one core and the other in the second core without danger of interraction. A graded index fibre is also available.

Title: Rotary regenerative heat exchanger - has rotor with circular disc surfaces parallel to flow directions of media
Inventor: WEINERT BERND DIPL ING
IPC: F28D19/04
Filed: 1979-08-07
Abstract: The regenerative heat exchanger has a rotor with a circular body driven about an axis in a housing, with portions of its periphery permanently protruding into adjacent parallel passages for first and second media flowing in opposite directions, and separated by a partition at the level of the rotor axis forming a sealed passage for the rotor. The rotor (2) comprises one or more closed circular discs (12), its axis of rotation (3) being at right angles to the flow directions of the two media (6,7), while the disc surfaces are parallel to these directions. Its direction of rotation is such that in each passage it moves against the flow direction, and its mean peripheral speed at the surfaces passing through the media is such that heat transfer is virtually solely determined by the heat transfer to these surfaces.

Title: Silicon oxide insulation for integrated semiconductor circuits - is produced by selective grooving of substrate of dimensions safeguarding continuous oxide film on heat treatment
Inventor: HIROBE KADOU
IPC: H01L21/316
Filed: 1979-12-07
Abstract: The formation of a thick silicon oxide layer is intended primarily for integrated circuit of metal-oxide-semiconductor (MOS) and bipolar type. The layer is to be produced in a given region of a suitable semiconductor substrate, whose production is the first step of the process. Then the material of the substrate is selectively removed and parallel grooves are formed in the given region. Ridges are similarly formed between adjacent grooves. The depth and width of the grooves and the geometry of their side walls are selected so as to provide a continuity of silicon oxide films, formed during heat treatment of the silicon substrate. The width of a ridge between two adjacent grooves also permits the formation of a silicon oxide film during heat treatment, which is carried out in an oxidising atmosphere which converts the ridges into silicon oxide and fills the grooves with this oxide. Pref. the width of the ridges is smaller than that of the grooves.

Each of the rectangles thus obtained is coordinated with three sliders which lie next to each other and are vertically adjustable. Their actuation through the keys and the levers produces the indication of the figure selected.

Title: Detection of impurities in hard rolled aluminium foil - for use in electrolytic capacitors, by examining formed sample with scanning electron microscope
Inventor: BECHTLER ALBERT DIPL PHYS DR
IPC: G01N23/04
Filed: 1980-08-26
Abstract: Foil will be etched and then used to mfr. electrolytic capacitors, so it is first inspected for impurities by subjecting an unetched sample to a forming operation of the type used in capacitor mfr. The formed foil sample is examined and assessed with the aid of a scanning electron microscope. From an earlier patent, 1614274, it is known that the etching of hard rolled foils produces a rough surface which is very desirable, but no impurities should be present on the foil's surface because they impair the quality of the dielectric coating and produce capacitors with poor electrical properties, e.g. a high leakage current. Foils of e.g. 1 kilometer in length are made, and the present invention ensures that their suitability for capacitor mfr. can be assessed at the earliest possible moment, i.e. before etching.

Title: Composite piston for IC engine - comprises hollow aluminium profile with copper sheet bent round one end to form crown
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N1/08
Filed: 1980-10-22
Abstract: The piston is made from a hollow aluminium profile and at least part of the crown is made of copper. The piston is made by using heat and pressure to deform a copper sheet so the latter makes a piston crown, with a short rim ending in a lip which is pressed by friction into the periphery of an aluminium profile. Instead of a continuous ring lip, the copper sheet can be provided with a conical tongue pressed into the aluminium profile. The good thermal conductivity of copper means that heat is rapidly conducted away from the crown of the piston.

Title: Non-slip coating for carpet backing esp. in automobiles - contains synthetic carboxylated and natural latex chalk and rubber granules

Title: Cable guide for electric lawn-mower - holds cable on runner travelling laterally along horizontal rail attached to mower handle
Inventor: MOELDERS VICTOR
IPC: A01D34/82
Filed: 1980-04-03
Abstract: The guide consists of two long parallel rails (16,18) joined by two short parallel bars (20) at their ends to form a rectangle. The upper rail is attached via clamps (12) to the handle of the mower. The guide can slide laterally through these clamps so as to project from one side or the other of the mower. The lower rail has a runner (24) to which the cable (30) is attached. The runner can travel along the lower rail. The arrangement allows the cable to be pushed to one side clear of the user. The clamps can be adjusted vertically on the handle so as to vary the height of the guide above the ground. The upper rail may have adjustable end-stops (32) to limit the lateral movement of the guide. Alternatively, a U-shaped guide may be employed instead of a rectangular one. In this case the ends of the U locate in the clamps on the handle and it cannot slide laterally. The long horizontal spine of the U carries the runner that holds the cable.

Title: Drive device for the needle-bar frame or the feed-dog carrier of a sewing machine
Inventor: VOGEL PETER
IPC: D05B19/00
Filed: 1981-01-03
Abstract: The drive movement (S11) for the needle-bar frame or the feed-dog carrier of a sewing machine, especially a high-speed industrial sewing machine, is generated by the superposition of a basic sinusoidal movement (S7), the frequency of which corresponds to half the stitch frequency, and a sinusoidal over-movement (S10), the frequency of which amounts to three times that of the basic sinusoidal movement. The amplitude of the basic sinusoidal movement is in the ratio of approximately 6:1 to that of the sinusoidal over-movement. Very quiet running, without appreciable mass forces, wear and noise generation, is achieved even at high speeds or stitch frequencies. <IMAGE>
