Patent WO-03088516-A1 (WO)
Inventor: DENK ROBERT
IPC: H04B1/707
Filed: 2003-03-24
Abstract: The invention relates to an end state of a shift register arrangement which is obtained from an initial state by N-fold iteration with an iteration rule predetermined by a characteristic polynomial f(x) in the n-th order.  In order to determine the end state, a characteristic tap mask for N' shift register operations is calculated.  N' shift register operations are carried out using the tap mask.  The n bits of an N-fold interated state of the shift register arrangement are also obtained.  If optionally, the necessary remaining N-N' iterations are carried out in another manner.

Abstract: Two individual monolithic semiconductor bodies are so mounted in a power transistor package with a heat conductive sole plate, that they form a four terminal hybrid assembly. The chip forming the power transistor stage is soldered directly to the sole late to which one terminal pin is also connected. Three other terminal pins pass through glass-metal insulating seals. From one of these a second connection is made to the above mentioned chip and also a connection as one electrode of the second chip which is soldered to a bent tag connected between the third pin and the remaining electrode of the first chip. Finally the fourth pin is connected as the third electrode of the second chip.

Title: Purifying water which contains gases
Inventor: HENRY BROWN MELVIN
IPC: C02F1/04
Filed: 1969-03-20
Abstract: Purifying water which contains gases Method comprises evaporating the water at sub-atmos. pressure to form a gaseous mixture containing steam and a gaseous component. A considerable part of the steam is condensed whilst simultaneously and/or subsequently particles of the uncondensed part of the gaseous component are continuously encapsulated in liquid. This encapsulation takes place in the upper part of an oblong chamber with a mainly vertical component. The formed particles move downward continuously and are compressed in the chamber by similar encapsulation of further particles of the gaseous components from the lower ends of the chamber are freed.

Patent DE-2007378-A1 (DE)
Title: Helical seam-welded tube prodn
IPC: B21C37/12
Filed: 1970-02-11
Abstract: Lengths of helical seam-welded tubing from metal sheets are produced on a multiroll bending machine followed by passage of the formed material through sets of rolls supporting the circumference, during which the seam is welded. The completed tube is then slit symmetrically into two at right angles to its axis and welded together again along the two previous end sections having tongue projections. This prevents the wastage of sheet resulting from trimming the ends of the welded tube straight.

Title: Continuous production of mesh filter elements - from 2 continuous bands of mesh which are joined and cut to form element on former
Inventor: COLE RODNEY DAVID
IPC: B01D29/00
Filed: 1972-09-07
Abstract: Mesh filter element from thermoplastic material such as nylon or polypropylene is made around circular former. Two rolls of mesh are joined and tensioned to form taught cover around the former. This then moves forward, taking the mesh with it, into a welding head where a second join is made behind the former, thus forming a circular element from two semicircular portions of sheet. the former then moves forward again into a cutting head where the weld is cut through the centre, leaving the element intact but also leaving the two bands of mesh joined. These then spring back on to the next former, since they are continuously tensioned, and the cycle repeated.

Patent DE-2333341-A1 (DE)
Title: Grid electrode for high-power electron tube - has starting assembly suitable for axial spark erosion forming thin, elongate strips
Inventor: MANZKE KLAUS DIETER
IPC: H01J19/38
Filed: 1973-06-30
Abstract: The starting blank for production of the grid strips is suitable for axial spark erosion and is formed by a dispersion hardened copper or copper alloy foil. The grid strips formed by the spark erosion are formed by thin long strips with intermediate thicker long strips, distributed over the electrode circumference. For stabilisation the long strips are interconnected by transverse ones. Thus the grid electrode transverse strip permit unobstructed guiding of the erosion tool in axial direction and simultaneously the formation of all longitudinal slits in the circumferential direction, but outside the erosion plane. The transverse strips may be arranged on the outer jacket surface of the blank and thus on the longitudinal strips of the grid electrode.

Abstract: A cutting machine for making holes in plastics discs, e.g. sealing discs for telecommunications cables, comprises a holding base for the disc and a bridge spanning across it; the bridge can be slid, rotated and locked relative to the base to give a variable centre of rotation for the cutter. The cutter is mounted pivotally on a spindle and driven by a hand crank to penetrate progressively into the disc. Pref. the spindle is journalled in a threaded sleeved in the middle of the bridge; the threads of the sleeve ad spindle are of fine pitch, thus giving a slow, progressive feed into the disc. Machine is for cutting flat or pot-shaped sealing washers for cables, e.g. from polyethylene, on site. Varying diameters and centres of rotation can be easily obtd.

A reversing arrangement responds to disengagement of the card from the first actuating element during the inward card movement for reversing the drive mechanism to move the card outward of the channel. A second actuating element responds to being disengaged from the outward moving card by actuating a printing mechanism which produces an imprint on a portion of the card in the guide channel. The actuating elements are microswitches.

Title: Machine for delivering hot bitumen to road surface - has inflatable body in storage tank for pumping purposes
Inventor: BENNINGHOVEN ERICH
IPC: F04B43/10
Filed: 1974-03-11
Abstract: The machine delivers hot molten bitumen from a tank and through a delivery line to the point of application. The molten bitumen is displaced from the tank by an inflatable bag which is fitted on the underside of the bitumen tank cover plate. The lower end of the inflatable bag is fastened to a point near the tank outlet at the bottom. This displacing bag eliminates the use of peristaltic pumps with flexible hoses which come periodically into contact with actuating rollers and slides and these hoses are hence subject to rapid wear. The bitumen is displaced from the tank by inflating the anchored bag. Inflating medium is blown into the bag through a valve on top of the cover plate.
Patent DE-2424424-A1 (DE)
Title: Safety fuse resistor - with ceramic rod carrying resistor layer with spiral turns at one end only
Inventor: NOEGEL OTTO DIPL PHYS
IPC: H01C7/20
Filed: 1974-05-20
Abstract: A safety fuse resistor for TV receivers is made from a rod-like carrier which supports a spiral resistance layer made of carbon, metal or metal oxide. The spiral shape of the layer is merely concentrated near one end of the rod. The resistos has a normal behaviour at nominal loads and normal lacquer can be applied without fear of overheating. Overloads cause a concentrated hot spot at the spiral end which evaporates and interrupts the circuit without producing an arc or red hot ceramics, to reduce possibility of fires.
