Title: Manual rolling device for suitcases
Inventor: HUEBNER WILHELM
IPC: A45C5/14
Filed: 1981-07-29
Abstract: A manual rolling device on a suitcase only provides real relief and pleasant independence for the traveller if the rollers are not located as previously at or in the rear corner of the suitcase, but below the bottom of the suitcase where they bear the entire load of the suitcase so that the traveller only needs to guide the rolling suitcase slightly. Such a rolling suitcase can be guided through the city on uneven streets and, with the very simple steering of the suitcase, through crowds. Even in rail cars, it facilitates transportation since, with the rolling suitcase, the traveller can not only walk beside it but also in the same track so that other travellers can easily pass by in the narrow corridors. Another great facilitation with the rolling suitcase is that the previously time-consuming transfers occurring at the suitcase check-in, when ordering "from house to house" and even, for example, at the customs check before and after travelling are dispensed with. The rolling suitcase thus provides a novel, happy travelling feeling.

Title: Sliding transfer device for a cigarette packaging machine
Inventor: OBERDORF MANFRED
IPC: B65B19/24
Filed: 1981-10-24
Abstract: The invention relates to a sliding transfer device for a cigarette packaging machine, a bottom-folding packer for slidingly transferring a pack, which is still open at the top and contains a cigarette block, from a hollow mandrel into a cell of a top-closing device, with a pusher acting on the cigarettes during the sliding transfer, towards the closed bottom of the pack, and a collector which is reciprocally movable relative to the cell. In order to design the device in a simple manner, and nevertheless to ensure that the pack bottom remains closed during the sliding transfer as a consequence of the force exerted thereon by the cigarettes, provision is made for the collector, which at the start of the sliding transfer is at a distance from the bottom of the pack, to possess air nozzles which are directed towards the bottom of the pack and, during the sliding transfer, are connected to a compressed-air source until the pack has reached the collector.

Title: Uniformly lying web connection with rolls rotatable about a point
Inventor: JENDRUSCH PAUL ING GRAD
IPC: B65H19/18
Filed: 1981-11-11
Abstract: A device for unwinding rolls and for the overlapped uniform web connection, particularly suitable for connection to paper-processing machines, in which the web is cut into sheets and an imbricated sheet path is subsequently formed, the imbrication operation not being influenced by the web connection. During the pasting operation, the expiring roll (26) is decelerated and the web of the decelerated roll (26) is pressed by means of the pressing-on beam (32) against the beginning of the web lying on the retaining device (38). In this case, this web is placed around the pressing-on beam (32) and cut by the knife (33) directly adjacent to the two-sided adhesive connecting strip. During this operation, the web required for the operation is removed from the magazine (51). The supply roll (25) is received without axles by two bearing arms (23+24). These bearing arms are mounted on the cross-beams (20+21) so as to be laterally adjustable in such a way that the supply roll (25) projects a long way in between the cross-beams (20, 21). As a result, the device can be kept small and, in spite of this, rolls with a large diameter can be processed. <IMAGE>

Title: Automatic power supply installation for isolated networks
Inventor: KNIRSCH HERMANN DIPL ING
IPC: H02J3/46
Filed: 1981-12-30
Abstract: The invention relates to an automatic power supply installation for isolated networks having a plurality of generators running in parallel, which is provided with the necessary monitoring, regulation and measurement devices. In order to prevent a mains failure as a result of a faulty generator, the reactive power outputs (Qi) of two or more generators are continuously compared with one another and the power differences ( DELTA  Pi) between the calculated nominal real power values (Pnom i) and the measured power values (Pact i) are compared, related to the averaged power differences of all the sets running, and, in addition, a continuous comparison ( DELTA  Pa i) is carried out between the sum of the time integrals of the actuating commands ( DELTA  Pnom i) and the change in the measured real power ( DELTA  Pact i) within a predetermined time ( DELTA  t). If the differences in the reactive power ( DELTA  Qi) components exceed a limit value (+/- Qlimit) an excitation fault is present, and if the power differences ( DELTA  Pi) exceed a limit value (+/- DELTA Plimit 1) and/or ( DELTA  Pa i) exceeds a limit value (+/- DELTA Plimit2) a diesel defect is present. The safety circuit, which disconnects unimportant loads, responds whenever a limit value is exceeded. One or more sets are started and connected so that the faulty set is detected and disconnected in accordance with this network support in the case of three or more supplying sets.

Title: Type-carrier cassette for a typewriter or similar office machine
Inventor: GERKEN HEINER ING GRAD
IPC: B41J1/24
Filed: 1982-02-27
Abstract: In the frequent change-over to foreign languages having different characters, to other kinds of script or also to special formula symbols, an easy change of the type wheel in printing units of typewriters or similar office machines is necessary. For this purpose, it is known to mount the type wheel in a cassette and to change it together with the latter. The object on which the invention is based is to make the design and handling of these type-wheel cassettes (21) even simpler, the aim being to mount the type wheel (31) in the cassette (21) so as always to be protected and to allow a secure coupling with the wheel receptacle (68) of the machine. For this purpose, the type wheel (31) on the one hand is mounted rotatably in the cassette (21) on one side, whilst on the other hand it can be supported on supporting collars (70, 71, 72) in the cassette, in such a way that the types (35) of the type wheel (31) are always protected from damage. Moreover, the outer faces of the cassettes (21) are so designed that a plurality of cassettes (21) can be stacked securely on one another. Furthermore, centring means arranged on the cassette (21) allow an alignment of the cassettes (21) in the receiving device of the machine in such a way that a secure coupling of the type wheel (31) in the cassette (21) to the wheel receptacle (68) in the machine is always guaranteed. <IMAGE>

Title: Method and apparatus for improving the operating characteristics of a wind energy converter and of working machine(s) connected thereto
Inventor: FRITZSCHE ALBERT DR ING
IPC: F03D9/28
Filed: 1982-04-27
Abstract: The method relates to the improvement of the operating characteristics of a wind energy converter (1) and of working machine(s) connected thereto. In this arrangement, the start-up moment is reduced by the selection of a small number (z) of veins on the rotor (4) of the wind energy converter (1). The energy transmission and optimum adaptation of the characteristic curves of the wind energy converter (1) and of the working machine(s) is accomplished hydraulically, a bypass or main circuit (14 and 12, 20 respectively) being held open in the start-up phase of the wind energy converter (1) and closed, with a time lag, in the advanced start-up phase, so that the wind energy converter (1) and the working machine(s) (3, 69, 70) are coupled to each other and adjusted, stepwise or continuously, relative to each other. <IMAGE>

Title: Quick-acting closure for containers with a lid
Inventor: SCHAUMANN DIETRICH
IPC: F16B2/06
Filed: 1982-05-26
Abstract: An eccentric closure for containers with a lid has an eccentric cam (4), through which a head bolt or hook bolt passes, with in each case two support surfaces (12, 13 or 14, 15) which are aligned parallel to one another and are offset relative to one another by approximately 90 DEG  with different spacing in pairs for the closed and the open position. In the closed position, the support surfaces (12, 13) with the larger spacing (a) come into contact in a fixing and securing manner on the one hand with the container (6) and on the other hand with the hook bolt. After turning, for example by means of turning tools which can be fitted on, about an axis of rotation transversely to the axis of the bolt and overcoming a dead centre position, the closure is released due to the smaller spacing of the other two support surfaces (11, 14). The support surfaces (12, 13, 14, 15) can be connected by curved surfaces (17, 19) with a maximum spacing which is larger than the closed position spacing (a). Guiding on the support strap of the container can be achieved by means of collars (9) perpendicular to the support surfaces (12-14). <IMAGE>

Title: Serial tetrad adder/subtractor mechanism in BCD 8421 code
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1982-06-28
Abstract: The subject-matter of the invention is a serial electronic tetrad adder/subtractor mechanism in BCD 8421 code, which can be switched from addition to subtraction and from subtraction to addition and has a tetrad adder/subtractor (1) which consists of five full adders/subtractors and two half adders/subtractors. According to the invention, constructing a BCD tetrad adder/subtractor as tetrad adder/subtractor mechanism is made possible by the fact that the tetrad adder/subtractor (1) is preceded in one of the two quadruple inputs by a recoding circuit (2) which recodes BCD numbers into BCD- plus-6 numbers, and that this tetrad adder/subtractor (1) is followed by a further recoding circuit (3) which recodes BCD-plus-6 numbers into BCD numbers. However, the recoding circuits (2 and 3) are only required for addition. For this reason, appropriate bypass lines are arranged for subtraction. <IMAGE>

Title: Insulating element for thermal insulation of building structures
IPC: E04B1/78
Filed: 1982-07-30
Abstract: An elongate, board-like insulating element made of thermoplastic for thermal insulation preferably of the outer walls of building structures has in cross section approximately the form of a flat trough, in the depression of which a thermally insulating and air permeable layer, e.g. of mineral fibres or the like, is disposed. With this design of the insulating element a relatively wide depression occurs on its reverse side, which is filled with a thermally insulating but air permeable layer. A loss of the heat transfer resistance which may occur in this area as a result of reduced material thickness of the insulation element itself is compensated by this, the air circulation, however, being only insignificantly restricted. <IMAGE>

Title: Method and device for producing a cable harness
Inventor: REISENBUECHLER WILLI HORST
IPC: H01B13/012
Filed: 1983-03-16
Abstract: In order to produce a cable harness, in which a plurality of leads of different length are combined to form a loom from which said leads branch out at various points, a method is proposed according to which the lead branches are led out from the loom along an envelope line of said loom, an elastic strip is used as cladding which is formed in such a manner that its longitudinal edges lie in the said envelope line, and in such a manner that these longitudinal edges are then connected to one another, for example by bonding, welding or by hooking on of attachment elements which are arranged on the longitudinal edges. In order to carry out the method, a device is used which has a funnel-shaped guide tube for the lead loom and the strip forming the cladding, which tube has a longitudinal slot for the lead branches to be passed out and is produced such that the strip is laid around the lead loom when said lead loom is passed through, its longitudinal edges lying in the plane of the longitudinal slot. In addition, the device has a means for connecting the longitudinal edges of the strips. Using the proposed method, the loom can be sheathed in one-piece cladding and it is possible to attach all the plugs to the leads at the start.
