Title: NC machine tool for furniture manufacture - has upper and lower tool holders which operate simultaneously
IPC: B23Q5/22
Filed: 1980-05-16
Abstract: Wooden furniture is manufactured on a numerically controlled machine tool. The machine tool has a base (1) with uprights (2) which support guide beams (3). The workpiece (13) moves through the machine on a chain or belt conveyor (4) and passes between an upper tool holder (9a) and a lower tool holder (9b). The tool holders are also able to move laterally on guides (7) and longitudinally on guides (8). As the workpiece moves through the machine work is carried out simultaneously on both faces by tools carried by the tool holders. The speed of production is thus increased and the velocity of the workpiece is independent of the dwell time between successive operations. It is also possible for operations involving tool movement in both longitudinal and lateral directions to be performed.

Title: Controlled conveyor for timber boards - moves boards to processing installation and stores them at stop for intervals determined by signals from installation
Inventor: HAIST KARL-JOACHIM DIPL ING
IPC: B65G47/88
Filed: 1980-07-02
Abstract: The appts. separately conveys boards transverse to their lengths to a processing installation where the boards are moved against a stop and are stored there while the conveyor action is maintained. At time intervals determined by a signal from the processing installation the board lying at the front nearest the stop is gripped by an issuing device and conveyed to the processing installation. The front most board in the layer of boards is always moved up to the pick-up area of the issuing device and is held there by the stop. The signal from the processing installation interrupts the conveyor action on the layer of boards and the stop is moved out of the movement track of the boards until the front most board has passed the stop when the latter is moved back into stop position and the conveyor action on the boards is resumed.

Patent DE-3047918-A1 (DE)
Inventor: BAHLE OTTO-GEORG DIPL ING
IPC: H04M1/65
Filed: 1980-12-19
Abstract: For switching over from playback of the owner's announcement text to recording a message from a caller, a pause of defined length is present on the announcement tape between the first and second (or end) parts thereof. This pause is recorded and on every run of the announcement tape through the apparatus the reading, recorded for the length, undergoes comparison with the pause of the announcement tape being transported. When the two values are the same, switch over takes place. In this way, it is possible to make certain of switch over without being dependent on the tape speed, and the circuit system may be made very much less complex.

Title: Device for controlling model railway systems, using the route principle
Inventor: JAKOB FRANZ DIPL ING
IPC: A63H19/24
Filed: 1981-03-03
Abstract: The invention relates to a device for controlling model railway systems, using the route principle. In this way, it is possible to operate a plurality of engines, protected in accordance with a pattern, without the engines having to be switched on and off by remote control. The rail system is split into electrically isolated route sections (o to u in Fig. 1). A common control signal can be used to control the sections, via a relay amplifier (1), and the points and signals, via the amplifiers (2, 3). Each route is characterised by a flipflop (7). Said flipflop can be set and reset by two or three buttons in the rail display (5), which are allocated to said flipflop and are linked by AND gates. Each flipflop output (A to N) can have allocated definitively to it, via a diode matrix, the control inputs (o ...) (W1 ...) (S1 ...) of the amplifier groups (1, 2, 3) which are required to form "its" route. The relay amplifiers are provided with a current flow signalling device which is electrically decoupled from the rail current. The flipflop circuits are constructed such that a simultaneous double allocation of route sections and the integration of occupied sections can be prevented. The modular construction permits any desired combination and hence matching to any system. <IMAGE>

Title: Method and device for indicating the position of a hoisting apparatus, movable and pivotable in a horizontal plane, in particular in a shaft-sinking rig
Inventor: NEUGEBAUER MARIAN
IPC: B66B3/02
Filed: 1981-04-27
Abstract: To detect the respective actual position along the horizontal travelling or pivoting path, proximity switches which can be actuated in a non-contacting manner and are sensitive to iron are arranged in fixed positions at uniform distances apart. The proximity switches are actuated by one or more position transmitters attached to the horizontally movable travelling or pivoting frame of the hoisting apparatus. By means of an audio-frequency transmitter with a transmitter frequency corresponding to the number of proximity switches, the actuating signal is transmitted to an audio-frequency receiver with a corresponding number of receiver frequencies. An arrangement of light emitting diodes, corresponding to the number of possible positions and distributed over the surface, serve to indicate the position. The light emitting diodes are activated by the respectively balanced frequency ranges. In a shaft-sinking rig, the invention enables the position of the shaft grab relative to the passage openings for the bucket passage which are made in the sinking platform to be continuously indicated. Here, the proximity switches are attached in a fixed position opposite the pivotable boom on which the grab winch is located, while the position transmitters are arranged on the boom. By the actuation of the proximity switches on account of the respective pivoted position of the boom of the shaft grab, the respective pivoted position of the shaft grab with regard to the passage openings is indicated to the hoist operator by the illumination of the appropriate light emitting diodes on the position-indicator board, which is located on the control panel of the hoist control platform.
