Patent DE-3110347-A1 (DE)
Title: Method for effective frequency spectrum utilisation in mobile radio systems
Inventor: REUDINK DOUGLAS OTTO
IPC: H04W16/24
Filed: 1981-03-17
Abstract: The invention relates to a method for effective frequency spectrum utilisation in mobile radio systems which are divided into a multiplicity of geometrically shaped cells. Mobile stations in each cell are served by at least one fixed station which has a directional antenna with a beam width which corresponds to the total area of the allocated cell. Each fixed station communicates with mobile stations in the allocated cell using separate primary channels in a first part of the frequency spectrum of the system if a mobile station is not exposed to any interference above a pre-defined interference level. A mobile station is switched over to a separate secondary channel within a selected segment of a second part of the frequency spectrum of the system if the interference in the mobile station exceeds the pre-defined interference level. Each selected segment which is used in neighbouring parts of adjacent cells lies within a different frequency sub-band of the second part of the frequency spectrum.

Inventor: VEY RICHARD AUGUST
IPC: B25C5/16
Filed: 1981-05-13
Abstract: A surgical stapling mechanism particularly suited for suturing skin and fascia and adapted to be mounted on or formed as part of an instrument having rectilinear thrust capabilities. The mechanism basically comprises a staple-housing portion which is adapted to store a plurality of surgical staples (30) in a linear array. The staple-housing portion contains a guide track (32) for orienting the surgical staples (30) so that the crowns (34) of the staples (30) lie in substantially the same plane. A spring arrangement (36) constantly urges the staple array in a forward direction. An exit aperture (37) provides a means by which the surgical staples may exit. Integral with the exit aperture is an anvil (40) which is used to form the staples (30) as they exit, one at a time. A delivery channel (42) provides a passageway through which the staples (30) move, one at a time, on their way toward the anvil (40). The delivery channel (42) defines a plane spaced from and substantially parallel to a plane defined by the crowns (34) of the staples (30) as they are stored in the staple-housing portion. A connecting channel (44) between the storage track (32) and the delivery channel (42) provides a path from the staple-housing portion to the delivery channel (42) for the passage of the surgical staples (30). Mounted for rectilinear movement is a pusher (50) which responds to a force supplied by the stapling instrument to advance a staple (30) through the delivery channel (42) and out of the exit aperture (37) for formation about the anvil (40).

Title: Method and device for converting the energy generated by oscillation of a mass into a continuously rotating drive force, especially for the operation of a motor vehicle
Inventor: BOEHNLEIN HORST
IPC: B60K25/10
Filed: 1981-10-15
Abstract: For converting the energy generated by oscillation of a mass into a continuously rotating drive force, especially for the operation of a motor vehicle or for generating electrical current etc. the kinetic energy of an oscillating mass essentially reciprocating in a straight line in one plane is used. This oscillation energy is transmitted by way of a drive connected to the oscillating mass and by way of a rotatable shaft, it being possible to insert a hydraulic arrangement (32, 33) or a worm gearing in order to obtain a very high operating pressure. In this case the drive is a drive pinion (4), connected to the oscillating mass, which pinion engages with a gear (5), rotatable in one direction. The gear (5) is connected at one end to a drive shaft (12), which can be extended in order to increase the stored energy (see 120). A driving gear (14), which is turned by the drive shaft (12), is firmly seated on the other end (13) of the shaft (12). This rotation is transmitted by way of a back gear or intermediate gear (15) to a flywheel (16) generating a continuous drive force (P). This drive force (P) can be taken off from the flywheel by way of a clutch (17) or employed for further use, for example to drive the wheels of a motor vehicle. <IMAGE>

Title: Method and device for closing one end of a folded tubular cover made of plastic and folded tubular cover made of plastic and closed at one end
Inventor: KUBO SEIJI
IPC: A22C13/00
Filed: 1981-10-21
Abstract: A folded tubular cover made of plastic is described which is closed at one end. One end region of the folded tubular cover is unfolded in order to form a container end region. The container end region is twisted at one point in order to form an inner portion of the container end region, a twisted closure region and an outer portion of the container end region. The outer portion of the container end region covers at least one part of the inner portion of the container end region, its inside being turned to the outside. In a preferred embodiment, the container end region is twisted at a point whose spacing from the free end of the container end region corresponds to once or twice the diameter thereof. The container end region is preferably inserted in the folded tubular cover. In another embodiment, the folded tubular cover is produced from regenerated cellulose and an opening is formed in the folded end region. A method and a device for producing such a folded tubular cover made of plastic and closed at one end are also described. No additional means are required for closing the tubular cover according to the invention, but only one end region thereof is used, as a result of which the entire region of the folded tubular cover is utilised. Since the outer portion of the container end region covers the inner portion thereof, the twisted closure region can withstand relatively large pressures despite its simple construction. <IMAGE>

Title: Device for cleaning an electric charge image carrier in copiers
Inventor: ELLINGER EBERHARD
IPC: G03G21/00
Filed: 1982-01-20
Abstract: The invention relates to a device for cleaning an electric, reusable charge image carrier in copiers, which after transfer to a suitable transfer material is cleaned from the remaining magnetic one-component developer. The aim of the invention is to use simple structural means to clean an electric charge image carrier from magnetic one-component developer that has not been completely transferred without the photoconductor being subjected to strong mechanical stress. The object of the invention is to employ a magnetic brush roller to produce a build-up of magnetic one-component developer between the surface of the cleaning sleeve and the photoconductor surface in such a way that the photoconductor is effectively cleaned, the build-up which grows continuously by virtue of the developer brushed off is simultaneously removed, and the excess developer is transported into a cleaning container. According to the invention, there is located below the magnetic brush and bearing against the developer that has built up a removal plate which forms with a front edge a narrow gap to the photoconductor surface and extends in a falling direction towards the cleaning container. <IMAGE>

Title: Method for detecting the conductors of a cable, in particular with the aid of an optoelectronic detection system
Inventor: EDINGER EGON
IPC: H01B7/36
Filed: 1982-02-25
Abstract: It is necessary in the preparation of equipment cables for the arbitrary sequence of juxtaposed equipment cable conductors to be determined and input into an appropriate control system. It is proposed in the prior application DE-PS 3,112,205 to use an optoelectronic colour detection system for the automatic detection of conductors. Such systems are very expensive. This expense can be substantially reduced according to the invention by providing the insulation (2) of the conductor (1) or conductors of the cable that are to be detected with a brightener that converts optical UV-light (5) into visible light (6), and by irradiating the conductor (1) or conductors thus treated in a darkroom using UV-light (5), which UV-light can be detected for example with the aid of a colour-sensitive photo diode (7). <IMAGE>
