Title: Information transmission arrangement
Inventor: VOGGENBERGER FRANZ DIPL ING
IPC: G08C25/02
Filed: 1982-10-28
Abstract: In an information transmission arrangement with two transmission paths having opposite transmission directions, where an instruction or signalling pulse telegram containing information in connection with acknowledgement signals can be transmitted in at least one transmission direction and an acknowledgement telegram can be transmitted in the other direction, in order to minimise waiting times in which no information can be transmitted and to reduce blocking of the telegram transmitter, the telegram transmitter (3) has transmission memories (5, 6, 7) in which the information to be transmitted is stored at least until the arrival of the acknowledgement telegram selectively allocated to each instruction or signalling pulse telegram. The transmission memories (5, 6, 7) are connected to a telegram acknowledgement coder (15) in order to allocate an acknowledgement signal to the instruction or signalling pulse telegram to be transmitted. To release the transmission memories (5, 6, 7) on arrival of the selective acknowledgement telegram, a release circuit (9, 10, 11, 12, 13, 14) is provided for every transmission memory (5, 6, 7), which release circuit is connected to a telegram acknowledgement decoder (18) at the receiving end which initiates the transmission of an acknowledgement telegram when an instruction or signalling pulse telegram is received. If the acknowledgement telegram is not received, the instruction or signalling pulse telegram is retransmitted. <IMAGE>

Patent DE-3304948-A1 (DE)
Title: Insulation wall for heat-treatment chambers
Inventor: BOESCH ALFRED
IPC: F27D1/06
Filed: 1983-02-12
Abstract: An insulation wall for heat-treatment chambers is assembled from plate-like parts in such a manner that two layers of plates are provided, the plates of one layer being laterally offset in relation to the plates of the other layer to such an extent that the gaps formed between adjacent plates in one layer are covered by the plates of the other layer. The plates themselves consist of a frame which is covered on one side by a sheet and filled with insulating material. A pair of rails, which passes through from one frame side to the other frame side in the plates, forms a corresponding gap which is covered by the sheet but free of insulating material and which overlaps the gap in the other plate layer. In both layers, the plates are laid on one another, with interposition of insulating strips on the frame and rail parts, in such a manner that the covering sheets are arranged on plate sides which face away from one another. In the gaps lying on one another, holding means for connecting the two plate layers are arranged.

Title: Rail-bound conveying vehicle with coding device
Inventor: SCHLECKER HELMUT DIPL ING
IPC: B61L23/00
Filed: 1983-02-26
Abstract: In order to achieve fully automatic setting of the coding elements regardless of the initial position of the coding elements and regardless of the travelling movement of the conveying vehicle in a rail-bound conveying vehicle with a coding device for setting of a destination coding, which device comprises at least a rotatable coding element, the varying angular position of which can be determined by reading devices arranged near the rails, it is proposed that for adjusting the coding element a drive which can be rotatably connected to the coding element should be arranged near the rail, that a reading device which determines the position of the coding element and a control device should be assigned to the drive and that the control device should include a comparator circuit which compares the signal of the reading device with a desired signal which can be input into the control device, and generates, in dependence on the difference between these two signals, a signal which makes the drive engage with the coding element and a signal which actuates the drive until the desired position of the coding element has been reached.

Patent DE-3332715-A1 (DE)
Title: Method and device for applying end sheets to sheet sections
Inventor: KLINGELHOEFER HANNSGEORG
IPC: B42C11/02
Filed: 1983-09-10
Abstract: Top and bottom sheets (12, 13) are applied to sheet sections (14), said top and bottom sheets being cut from large sheets (24) by a transverse cutter (26) arranged between the feeder (22) and the application point (33). As a result, reliable adherence to a colour sequence and the same colours of the bottom and top sheet can be maintained in the products because either the top and bottom sheet (12, 13) are cut from the same large sheet (24) or, in a variant, the successive colours are on one large sheet in each case, such that the sequence and identical colour of the bottom and top sheet can also be maintained in two application devices. <IMAGE>
Patent DE-3333623-A1 (DE)
Title: Corner joint
Inventor: BERGLER OTTO
IPC: B27C5/02
Filed: 1983-09-17
Abstract: A partly mitred corner joint has projections and recesses on each mitre surface of the workpieces to be joined, which projections and recesses are orientated perpendicularly to the mitre surface. A corner joint of this type is positive-locking and self-retaining so that a frame provided with the covering corner joint need not be inserted into a press device after the glueing. Clamping elements are also dispensed with. The projections and recesses can be made, for example, as dowels and corresponding bores. But it is also convenient to design them as projecting edges and corresponding grooves. In this case, in particular if they extend over the entire width of the mitre surface, they can be machined in a very simple manner with a profile router or a profile plane, it also being possible to simultaneously cut or plane the two workpieces to be joined, so that only a single operation is necessary for producing the corner joint.

Patent DE-3402944-A1 (DE)
Title: Arrangement of two racks on two upright supports
Inventor: EBERLEIN HERBERT DIPL ING
IPC: B62B3/18
Filed: 1984-01-28
Abstract: In transport trucks or sales stands, it often happens that loading the lower loading surface with relatively high objects leads to difficulties if there is a further rack above the lower loading surface. The novel arrangement (1) of two racks (3, 4) on two upright supports (2) allows the upper rack (4) to be pivoted away upwards. In this case, the lower rack (3) of the racks (3, 4) arranged at different heights is preferably attached rigidly to the supports (2) and the upper rack (4), in contrast, is attached to the supports (2) so as to be pivotable upwards about a horizontal axis (10), the rear wall (13) of the lower rack (3) being extended upwards to the extent that it also forms the rear wall (13) of the upper rack (4). Thus, due to its lack of rear wall, the upper rack (4) does not conceal the access opening to the lower rack (3) when it has been pivoted up. <IMAGE>

Patent DE-3415032-A1 (DE)
Title: Method for interference-resistant radio transmission
Inventor: HEROLD ANDRIES
IPC: H04B1/713
Filed: 1984-04-19
Abstract: In communications via radio paths, transmission quality is impaired not only by atmospheric interference but also by signals which desirably or undesirably make use of the same or of an immediately adjacent frequency. To achieve greater resistance in such cases to interference from signals of this type, it is known for a frequency jumping method to be used in the signal transmission in which the radio carrier frequency is modified in jumps at short intervals according to a pseudo-random pattern within a pre-defined frequency range. Practical experience has shown that here too the noise power produced by signals within the frequency band used by the jump frequencies can still be relatively high. It is proposed for further improvement of resistance to interference to monitor the jump frequencies for possible interference and to prevent their further use if an interference frequency occurs which can no longer be tolerated. <IMAGE>
