Title: Bolt lock
Inventor: EUDENBACH WILHELM
IPC: E05C19/14
Filed: 1982-11-29
Abstract: A bolt lock for locking swing-down tailboards of heavy goods vehicles and trailers consists of a shell-shaped housing shell (10) which is embedded in a tailboard and in which a hand lever (12) is mounted pivotably for moving a bolt hook (11) between its locking position and its open position. The hand lever (12) is connected to a bolt hook (14) by means of connecting links (13). The free ends of the connecting links are mounted movably about bearing pins (27). The bearing pins extend from an articulated piece (30), arranged loosely on the bolt hook (11), transversely to the direction of movement of the bolt hook (11) into longitudinal guides (28) provided in the housing shell (10). Furthermore, a setting piece (31) located at a specific distance from the articulated piece (31) is arranged on the bolt hook (11), a compression spring (34) being supported under prestress between the articulated piece (31) and the setting piece (30). For a stable mounting and guidance of the bolt hook (11) in the housing shell (10), in the region of the threaded shank (15) there is a tunnel-like guidance (52), into which projects the end of the threaded shank (15) located on the housing. Since the bolt hook (11) pivots out of its locking plane in its open position, the exit orifice of the tunnel-like guidance (52) located on the same side as the hook is widened in a funnel-shaped manner, so that the hook is not impeded in its vertical pivoting movement <IMAGE>

Title: Data transmission device
Inventor: LEOPOLD GERHARD
IPC: H04L7/033
Filed: 1982-11-30
Abstract: In order to transmit serial data streams comprising a plurality of words containing a high number of bits via limited-bandwidth transmission channels, the serial data stream is converted by means of a multiplexer (3) into two data sub-streams with half the transmission speed which are transmitted separately from one another via dedicated channels and which are recombined at the receiving end by means of a multiplexer (12) to form the original data stream. In order to identify and allow for transit time differences between the two channels (5, 8), a modulator (2), connected to the data source (1), is provided on the source side, a demodulator (13), connected to the data sink (14), is provided on the sink side, and a bit string converter (15, 16) is provided on both the source side and the sink side whose output is connected to one input of the modulator (2) or the demodulator (13) and whose input is connected to the output of the modulator (2) or the multiplexer (12). A testing device (17) which serves to identify the transit time differences between the two transmission paths is connected to the output of the demodulator (13), with which testing device a transit time component (11) is controlled which is disposed in one of the two transmission paths. <IMAGE>

IPC: H02G11/02
Filed: 1982-12-17
Abstract: The device for winding up a cable consists of a housing (10) having at least two inlet and outlet guides (16, 18) for the cable (20). A cable drum (22) is supported such that it can rotate in the housing, on which drum (22) the cable can be fixed at a central point. Since there is no relative movement between this fixed point of the cable and the cable drum during rotation of the latter, it is provided that contacts for the connection of the cable to an electrical device (32) which is connected to the cable drum, or at least a further cable which can be wound up on the cable drum, are arranged on the cable drum. In this way, for example, a foot switch of a standard lamp can be combined with a cable winding-up device. The electrical device (32) in the cable drum (22) also does not prevent detachable mounting of the latter, which is advantageous anyway, a hook which is constructed on the inner end of a spiral spring that acts on the cable drum being detachably engaged with a hook on a central journal.   <IMAGE>

Patent DE-3310619-A1 (DE)
Title: Control device for target positioning in machine tools with a spindle
Inventor: BERGMANN LUTZ DIPL ING
IPC: G05B19/23
Filed: 1983-03-24
Abstract: In this control device for target positioning in machine tools, a spindle (1), for a tool exchange, is to be brought into a predetermined target position. During a first mode of operation, "speed control", the spindle speed is in this connection lowered to such a low initial value that the stopping of the spindle in the target position during the subsequent second mode of operation, "positional control", is possible within a single spindle rotation. To detect the position of the spindle (1), a pulse generator (5) is provided on the spindle centre line, which delivers generator pulses (P) and a reset pulse per rotation to a pulse counter (7). In order to make possible an adaptation of the counter control to the pulse generator (5) with optional increment number (N) per rotation, the counter (7), in the "speed control" mode of operation after reaching the counter state zero, is not set to its maximum value but to a value corresponding to the increment number (N) of the pulse generator (5) and counts down subsequently. The target position is defined as the increment difference (Z) between the zero mark of the pulse generator (5) and the target in such a manner that, on the appearance of the zero pulse, the increment difference (Z) is in the counter (7) and the counter content is exactly zero on reaching the target position. <IMAGE>
Patent DE-3312128-A1 (DE)
Inventor: HOELL ROLAND DIPL ING
IPC: B41F23/08
Filed: 1983-04-02
Abstract: In response to a stop command such as a printing disturbance signal, the transfer of varnish to the varnish applicator roller is shut off but the feeding of sheets through the varnishing unit is not immediately shut off; rather, a few remaining sheets are thereafter fed through the varnishing unit before the varnish applicator roller is thrown off from the cooperating cylinder and the machine drive is shut off. The few remaining sheets remove the residual varnish from the varnish applicator roller so that when printing is resumed the newly printed sheets do not stick to the varnish applicator roller or the cooperating cylinder. In a preferred embodiment a preselection counter, clocked by sheet feed cycles, determines the number of remaining sheets.
Patent DE-3318002-A1 (DE)
Title: Flying vehicle having a lifting-body configuration
Inventor: PAHLING WALTER DIPL ING
IPC: B64C39/10
Filed: 1983-05-18
Abstract: The subject-matter of the invention is a flying vehicle having a "lifting-body" configuration. This allows the use of dynamic and static lift if the enclosed volume is filled with helium or hot gas. The exhaust gas of the aircraft motor, for example, can be used as the hot gas. The above-mentioned configuration is intended to be implemented by means of a very light supporting structure consisting of CFC tubes and film stretched between them. The proposed flying vehicle offers enormous safety advantages (in addition to low production costs) over conventional (ultra-light) sport aircraft as a result of:     - extremely short take off and slow flying characteristics, - maintenance of the flying capability and control ability even if one type of lift is lost, and - protection of the pilot against injuries in the event of a crash, as a result of the air-cushion effect.   A car is adequate as transportation means, because of the dismantling capability.

Title: Line protection circuit breaker having an arc starting aid
IPC: H01H73/18
Filed: 1983-09-27
Abstract: In a line protection circuit breaker having two arc track rails (14, 28) which lead to an arc chamber (32), the one track rail (14) supports the stationary switching contact (16), and the other track rail (28) extends up to a point close to the moving switching contact (18) in its open position. One of the supply lines (12, 24) leading to the switching contacts (16, 28) has a line section (42) which is led along directly in front of the arc chamber (32) and conducts the current in the same direction as in the arc (50). According to the invention, this line section (42) is part of a conductor loop (38-46) which leads to the moving contact (18) and which (at 48) is conductively connected to the second arc track rail (28) in front of the said line section (42). This results in the said line section (42) attracting the arc (50) only until it jumps over onto the second arc track rail (28) and then having no current flowing through it, so that the arc can run further into the arc chamber without hindrance.

Patent DE-3402126-A1 (DE)
Title: Device for the protection of multiphase electrical machines
Inventor: MAIER FRANZ DIPL ING DR
IPC: H02H7/06
Filed: 1984-01-23
Abstract: This device is provided for the protection of multiphase electrical machines having winding phases (LR, LY, LB) in a star circuit against fault currents. It has a first relay (R1) which responds to a fault of one of the winding phases in the region of the faulty winding phase (for example LR) remote from the star point, and a second relay (R3) which responds to a fault of one of the winding phases in the region of the faulty winding phase (LR) close to the star point. In the event of a fault, this arrangement is intended to detect, in a simple manner, both the winding phase (for example LR) having an earth short and the location of this earth short in this winding phase. This is achieved in that each phase (for example R) has allocated to it a first differential current transformer (for example WR) and each combination of two of the phases (for example R,Y) has allocated to it a second differential current transformer (for example WRY). In this case, the primary windings of the second differential current transformers (for example WRY) are formed by fault current measurement circuits (for example ZR, ZY) which are arranged in the opposite sense and in which the secondary windings of the first differential current transformers (for example WR, WY) of the associated phases (for example R,Y) are connected. <IMAGE>

Title: Free-running flyback-converter switched-mode power supply
Inventor: PERUTH GUENTHER DIPL ING
IPC: H02M3/335
Filed: 1984-02-17
Abstract: The invention is based on a refinement of a flyback converter switched-mode power supply as is described in DE-OS 3,032,034. The object is to increase the starting speed of the flyback converter. According to the invention, the known flyback-converter switched-mode power supply is accordingly modified in such a manner that the two half cycles supplied by the full-wave rectifier to which the AC supply network is applied are made use of for the switching-on supply of the control circuit of the switched-mode power supply. In the case of the known refinements, only the one half cycle is used. Furthermore, as a comparison between Fig. 1 (prior art) and Fig. 2 (preferred refinement of the invention) shows, the invention can be implemented without any additional cost in terms of switching means. <IMAGE>
