Title: Method of removal of printed sheets from printer - has suction belt which guides sheets into cassettes
IPC: B65H31/30
Filed: 1991-11-29
Abstract: The printed sheets (1) are removed from a printing machine by grippers attached to an endless chain (3) which is guided by chainwheels mounted in an overhanging arm (4). The sheets are removed from the chain by a suction belt (5) which directs the sheets into a guide (7) which deposits the sheets in cassettes (8).

Patent DE-4143326-A1 (DE)
Inventor: GARROD ADRIAN GEORGE
IPC: G01S7/02
Filed: 1991-09-11
Abstract: Pulses are transmitted using orthogonal polarisations. In the receiver, there is provided a polarisation splitter operative to separate received echo signal returns into two signals having orthogonally related polarisation characteristics 6, 7. The amplitude and relative phase of the two signals are measured, computing means 9 responsive to the amplitude and relative phase of the two signals for each of two successive radar echo signal returns having orthogonally related characteristics being provided for computing co-polar nulls appertaining to a radar target. Storage means contain data appertaining to co-polar nulls for specified targets. Comparator means responsive to the stored data and to the computed co-polar nulls provide an output signal indicative of target identity when correspondence obtains between a stored and a computed co-polar null.   <IMAGE>

Title: Heat shrink sheath e.g. for telephone cable splice - consists of crosslinked polymer with gas and water vapour barrier plastics film not impeding shrinking
Inventor: MARX KARL-HEINZ
IPC: C09J7/29
Filed: 1992-01-08
Abstract: Heat-shrink sheath for substrates, e.g. telephone cable splices, consists of a first layer of crosslinked polymer (I) and a second layer of gas- and vapour-impermeable material (II). The novel features are that (a) (II) consists of a plastically or elastically deformable plastics film with a wall thickness of 10-250, pref. 25-100 microns; and (b) the sheath has a water vapour permeability (WVP) of max. 0.03 g/m2 day. The sheath has a hot melt adhesive layer (III) on one surface and (II) is between (I) and (III). (II) consists of PVA, EVA, polyacrylonitrile, PVDC or PVDF; and (I) of polyethylene with embedded flakes of polyamide. ADVANTAGE - The water vapour barrier does not impede shrinkage and the sheath can be made economically. In an example, (I) was made from a mixt. of 50 pts. polyethylene, 40 pts. EVA and 10 pts. C black, which was treated with 1% vinylmethoxysilane and extruded to a tape with ca. 4 mm wall thickness. The tape was covered with a PVA film (ca. 200 microns thick) and crosslinked in steam at ca. 95 deg.C, avoiding the use of harmful radiation. The crosslinked prod. was drawn by 300-500% at 150-180 deg.C and cooled in the drawn state. The wall thickness was then just over 1 mm. After applying (III), the prod. was ready for use. The PVA film reduced the WVP considerably.

Patent DE-4215561-A1 (DE)
Inventor: FRANKE JOERG DIPL ING
IPC: B23K26/142
Filed: 1992-05-12
Abstract: A method is disclosed for removing material from moving metal workpieces (10), in particular for cutting sheet metal. It entails preheating, without melting, the surface (11) of the workpiece (10) to a temperature at which ignition is triggered by a combustible gas (12) directed onto the preheated section (13) as a jet under pressure, while burnt material from the workpiece (10) is blown away from the cut recess (14) thus produced. In order to achieve smooth edges on large-gauge workpieces with a relatively high feed-rate, a laser beam (15) is also directed onto the cutting front (16) in the cut recess.
