Title: Serial transmission to computer - has microcomputer controlled storage of data followed by transfer to main computer
Inventor: KINNE JOACHIM DIPL ING
IPC: H03M9/00
Filed: 1980-07-08
Abstract: The character transmission system is for serial data converted into parallel form and is designed for fast processing rates coupled with a capability for transmission to a wide range of units. Character data is generated by a processor (1) and is transmitted by a serial link (2) to a serial to parallel converter (3).

Title: Mfg. structured surface on coating of paper or foil - by two successive coatings of different thickness and polymer concn.
Inventor: BROERKEN HERBERT ING GRAD
IPC: D06N7/04
Filed: 1980-10-04
Abstract: Structured surface is produced on a sheet of paper or foil by multiple coating. Firstly a solvent mixt. contg. dissolved polymer is applied as a thin coating onto the (moving) paper or foil and at least partly dried. This is followed (immediately) by a second, thicker coating of a liq. which may be the same as the first but pref. has a greater concn. of polymer in the solvent, after which a first drying phase (5) is applied for both the coatings in which the rate of drying is regulated by the flow rate of air and its temp. so that the upper, second layer (3) achieves the desired surface structure (6) without a too rapid increase in the concn. of the polymer and without too much formation of skin. Pref. a first solvent and at least one other solvent are mixed in proportions by which the steepness of the flanks of the minute cells of the structured surface can be regulated (according to the relevant proportions) and thus the roughness can be regulated. Used for the prodn. of a semi-matt or similar surface on paper or similar foil, with the attendant advantages of insensitivity to scratching, lack of reflection, etc. The method enables the following three parameters to be independently regulated. The total thickness of the dry coating; the roughness depth of the surface; and the dia. of the minute surface cells.

Patent DE-3043634-A1 (DE)
Inventor: MEUSBURGER GUENTHER DIPL ING
IPC: H02P8/02
Filed: 1980-11-19
Abstract: A CMOS pole-reversing driver circuit (1) with an external transistor connection (8) and a cyclically active short-circuit arrangement (21) to activate a stepping motor (2) is intended to allow higher output current via the bridge diagonals without significantly increasing the space requirement and is intended to require no externally connected capacitors for regenerative braking and only the two circuit terminals (5) for the external connection (8) which are required in any case in a driver circuit (1) of this type to activate the stepping motor. For this purpose, the half-bridge (7.14), whose bridge elements are space-saving n-channel field-effect transistors (14), is implemented within the integrated circuit (6); the second half-bridge (7.15) is implemented as an external connection (8) in the form of a component (18), with two bipolar pnp-power transistors (15), which is connected in parallel with the stepping motor (2). The short-circuit arrangement (21) contains two integrated, small-area p-channel potential connections (19) which supplement the integrated first half-bridge (7.14) to make the complete driver circuit (1) if high power is not required in the bridge diagonals and the external connection component (18) can therefore be left out. <IMAGE>

Title: Process for producing and/or renewing a marginal strip of a road and marginal-strip finisher for carrying out the process
Inventor: SCHLICKSBIER JOSEF ING GRAD
IPC: E01C19/48
Filed: 1981-01-16
Abstract: The invention relates to a process for producing and/or renewing a marginal strip of a road. The process is characterised in that the marginal-strip material is first worked in from a supply container, by means of at least one working-in device, to a level which is higher than the level (desired level) of the finished marginal strip, and in that the marginal-strip material is then milled off or stripped off to the desired level by means of a trailed milling cutter, and the excess material is fed to the supply container again.   <IMAGE>

Title: Motor vehicle headlamp
Inventor: BERMPOHL HORST
IPC: F21V29/15
Filed: 1981-02-19
Abstract: The dippable motor vehicle headlamp has a parabolic reflector which is produced from thermoformable plastic. When the dipped beam is switched on, a portion of the reflecting surface is screened with respect to the coil producing the dipped beam. Integrally formed on the rear of the reflector are reinforcing ribs which extend parallel to the central plane, which is vertical and points in the direction of the optical axis, and extend over the largest portion of the reflector region screened with respect to the dipping coil as far as the reflector region responsible for illuminating the section immediately below the bright/dark boundary. Such an arrangement of the reinforcing ribs lends the reflector high strength and rigidity.

Title: Process and apparatus for relieving the tensile force on SZ-stranding machines
Inventor: MUELLER BERND DIPL ING
IPC: H01B13/02
Filed: 1981-03-30
Abstract: The invention relates to a process and apparatus for relieving the tensile force on SZ-stranding machines. The aim of the invention is to produce a uniform stranded structure of appropriate quality by means of SZ-stranding machines. The object according to the invention is, therefore, to reduce to a minimum the tensile-force load on the individual stranding elements before entry into the SZ-stranding machine and to achieve a synchronism of the stranding elements with one another. This object is achieved in that the individual stranding elements (wires) coming from run-off stands or other stores are fed to a guide and thereafter are laid around in an ordered manner, at a looping angle  phi , over a driven draw-off disc arranged just in front of the stranding apparatus, the circumferential speed V1 of the draw-off disc being a small amount higher than the draw-off speed of the main draw-off or the stranding speed Vs of the stranding apparatus, and the stranding elements being guided from the draw-off disc by way of the perforated disc to the stranding apparatus with a greatly reduced tensile-force load. <IMAGE>

Title: Luffing crane
Inventor: PROBST WALTER DIPL ING
IPC: B66C23/66
Filed: 1981-04-27
Abstract: The luffing crane is constructed according to the double-link principle and has a compression link (2), a tension link (3) and a head jib (4) linked to their ends. To improve the stability of its four-bar mechanism (1-4), an additional jib (10) is attached to the front end of the head jib (4). The end of the jib (10) opposite the load is connected to one of the links (2, 3), preferably the compression link (2), by a link bar (11). In the position of maximum working radius of the head jib (4), its reach is extended by the additional jib (10). In the position of minimum working radius, the additional jib (10) is swung back so that the slewing angle of the head jib (4) need not be so large. The head jib (4) cannot therefore move into a position in one line with the compression link (2), which position would be unstable.

Title: Switching and mixing chamber, preferably for flexographic and intaglio printing machines
Inventor: KOEWENER GUENTER
IPC: B41F23/04
Filed: 1981-05-25
Abstract: A switching and mixing chamber, preferably for flexographic and intaglio printing machines, is provided with four connectors in the cylindrical outer surface of the chamber, which is closed at the sides by circular disc-shaped walls, for the supply and discharge of hot air and the supply of fresh air and discharge of fresh air or circulation air or a mixture of fresh air and circulation air. Inside the chamber, an adjusting device is fastened on a shaft mounted centrally in the circular disc-shaped chamber walls, which adjusting device in each case connects an input nozzle to an output nozzle or mixes circulation air with fresh air in intermediate positions. In order to improve a low-resistance guiding of the air and the possibility of connecting opposite nozzles to one another, the adjusting device consists of two guide plates (13, 14) which are curved in the manner of an arc and with their side edges touch or almost touch the circular disc-shaped end walls (2, 3) and with their end edges touch or almost touch the cylindrical outer surface (1) of the chamber. The guide plates bound a channel between them and lie in each case with their end edges in the region of the outer edges of the interconnected nozzles facing the channel bounded by the guide plates (13, 14). <IMAGE>
