Title: Pipe plugging machine is hand gun - with alternating right and left rotating drive to cut and insert plugs
Inventor: LIEGMANN KARL-HEINZ ING GRAD
IPC: B25B27/10
Filed: 1980-02-25
Abstract: An apparatus for inseting plugs into the ends of pipes or tubes, esp. plastics plugs, is constructed in the form of a pistol. This contains a rotary drive which can execute right-hand and left-hand movements through an angle of 45 deg. A strand of plug material is fed into the pistol through a guide and is cut at blades as follows; the right-hand angular movement of the drive rotates a horizontal-axis wheel which in turn drives a vertical-axis drive roller thus conveying the strand forwards by one plug length, so that the strand bears against a counter-blade; the drive is then rotating to the left through 45 deg., now driving a horizontal-axis drum contg. chambers spaced at intervals of 45 deg. and each having at its inlet a cutting blade. This rotation therefore cuts the strand between the two blades; further rotation brings the plug in its chamber in the drum opposite to a thrust cylinder, which expels the plug out of its chamber into a guide nozzle which is fitted into or onto the pipe end. Pref. the guide nozzle and the blades are replaceable. Pref. also, the drive has a freewheel in the left direction and the drive wheel has a freewheel in the right direction. In particular, for the insertion of plastics plugs or stoppers into the ends of pipes for shipping and despatch. The apparatus enables the plugs to be inserted mechanically and thus eliminates manual work.

Title: Munition cartridges formed from fibrous slurries - with woven inlay rolled in during felting process
Inventor: OVERSOHL WILHELM DIPL CHEM DR
IPC: F42B5/188
Filed: 1980-03-08
Abstract: A mfr. of munition mouldings, e.g. cartridge casings or charge containers, consists of rolling fabric inlays into the crude felt during the felting operation. The woven fabric inlays may be rolled through the entire thickness of the crude felt or only into the outer skin or inner skin of the felt. The inlay may be rolled into the entire length or parts of the length. By rolling woven fabric inlays into the felt, additional strength is provided; for example, in the case of a cartridge casing this prevents breaking during rough handling. The method is partic. important where casings contain powdered explosive.

Title: Monitoring charging time of kegs - using marks on container ends detected by sensors
Inventor: TILL HEINZ
IPC: G06K7/10
Filed: 1980-08-29
Abstract: An arrangement monitoring the charging time of cylindrical containers, esp. kegs, in the drinks industry, automatically monitors the time at which containers are put into operation with regard to the need to recalibrate them. A container can be rotated about its axis and, if required, moved perpendicular to the axis in a monitoring station. A position mark (PM) on a first circle (K1) on the keg is scanned by a first sensor (AK1). A second sensor (AK2) scans marks (EM,KM,AM) on a second circle (K2) for switch-on, time at which operation starts, and switch-off. These marks have defined positions w.r.t. the position mark (PM). The first sensor activates the second on finding the position mark. The second sensor activates and deactivates a code mark reader on finding the on and off marks respectively.

Title: Gate or door with stabiliser
Inventor: DOERING ERICH
IPC: E06B3/72
Filed: 1981-03-23
Abstract: A gate or a door with a gate leaf or gate covering on a closed or open frame consisting of open U-shaped, Z-shaped, angular or similar profiled bars has at least one stabiliser which is designed as a torsionally rigid tubular profiled bar which is closed on the longitudinal side, and is connected to opposite open profiled frame bars torsionally rigidly, e.g. centrally or at their two ends. In this manner, it is not necessary to put on diagonal struts or to make the entire frame from square or rectangular tubes which are welded to one another to achieve the required torsional rigidity. It would then be disadvantageous that all bores and openings on the finished profiled bar would have to be drilled or milled. <IMAGE>

Title: Cleaning device for electrophotographic copiers
Inventor: HANDWERK KARL-HEINZ
IPC: G03G21/00
Filed: 1981-10-09
Abstract: In a cleaning device for electrophotographic copiers, an elastic cleaning blade (6) which is glued to an exchangeable holder (5) is pressed with its cleaning edge (6a) against the surface of the recording carrier (7). The cleaning blade bends somewhat under the action of the pressure force and in so doing is supported with its rear against an edge (5a) of the holder (5). So that it is impossible for there to form on the edge (5a) any irregular adhesive edge which impairs the uniform bending of the cleaning blade and thus the correct bearing of the cleaning edge against the recording carrier, a catcher groove (5e) for superfluous adhesive is arranged on said edge. <IMAGE>

Patent DE-3145919-A1 (DE)
Inventor: HAUSSMANN WOLFGANG DIPL ING
IPC: H03D3/00
Filed: 1981-11-19
Abstract: Method for demodulating time-discrete frequency-modulated signals. The method includes combining sequential equidistant samples of a signal to be demodulated for deducing the instantaneous frequency of the signal to be demodulated. The improvement includes dividing a first vector sum of samples forming a dividend by a second vector sum of samples forming a divisor. Each sample is a complex number represented by a vector. The vector sum of the dividend has a phase that is offset from the vector sum of the divisor by a phase angle equal to n times pi, wherein n is any integer. The division of the vector sums is advantageously performed by a ROM in which all the division results have been stored and which can be accessed by the divisor and the dividend for quickly obtaining the division result. Delay lines and summing circuits are used for combining the samples into the dividend and the divisor.

Title: Paper container made of heat-sealably coated cardboard
Inventor: CLAUSS GERHARD
IPC: B65D5/64
Filed: 1982-03-10
Abstract: A paper container made of coated cardboard and having a wound container casing and a container bottom connected to this is described. To seal off the open cut edges of the mutually overlapping casing ends, the container casing is double-walled, the two casing blanks being glued or sealed to one another so as to lie on one another in an offset manner, in such a way that in each case one blank projects somewhat relative to the other in the overlap region. The projecting edge is folded round in such a way that the respective open cut edge of the inner container casing rests with a butt edge on the corresponding cut edge of the outer container casing, so that, after the sealing of the container casing, there are no longer any open cut edges. The open cut edges in the region of the container bottom and of the upper mouth roll can also be concealed in a similar way. The invention also describes a plurality of processes for producing double-walled paper cups of this type.

Title: Ski stick holder
Inventor: BEHNCKE BERNHARD H
IPC: A63C11/22
Filed: 1982-05-21
Abstract: The ski stick holder (drawing I) provides the skier with the possibility of attaching the ski sticks to the ski. The holder (1) has a vertical bore (2) which receives the ski stick. In order to attach the holder to the ski, said bore is continued (5) downwards with a smaller diameter. The edge thus resulting gives the attachment screw stability. A projection (3) on the underside of the holder secures the latter against rotation. A cross-bore (4) allows the snow collecting in the ski stick holder (1) to be pressed out laterally. The alternative designs a) - drawing II - and b) - drawing III - are variations of the basic model already described. A further alternative design (without drawing) results from mounting a sleeve on the outside of the front jaw of a ski binding. This solution additionally provides an easily recognisable left/right marking of the skis. <IMAGE>

Title: Vacuum-switch/contact arrangement with a device for generating an axial magnetic field
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1982-07-20
Abstract: An axial homogeneous magnetic field is generated in a vacuum switching container by means of an energising arrangement which is combined with the switch contacts. This takes place in a novel manner in that two axially opposite [lacuna] are provided which can move relative to one another and are provided in approximately shell-shaped bodies on the edges with properties which are equally inclined with respect to the switch contact axes. The notches are made at equal intervals along the circumference of the shell. As a result of the notches, individual current conductors are produced which, in totality, in each case form an energising coil. On their end surfaces there are contact and electrode discs which are compact or are even split into individual elements. The essential feature is the stamped-out continuous radial symmetry of this contact, switching and energising arrangement.
