Title: Device for pushing rods into a drawing die
Inventor: BUELTMANN RUDOLF
IPC: B21C5/00
Filed: 1981-03-27
Abstract: The pushing-in device has two wedge-shaped jaws (5) which can be displaced with respect to insertion parts (6), acting as control parts, by means of a piston (12) or the like, for adjustment of the aperture size to the different rod cross-section sizes and for clamping the rods (2) and which jaws (5) are arranged so as to taper towards the front, pointing in the direction of the drawing die (3). This jaw arrangement ensures that the free buckling length (X) between the jaws (5) and the drawing die (3) is kept relatively small, so that the danger of bending while the rods are being pushed in is eliminated as far as possible. The thinner the rods (2) which are taken hold of, the wider apart the jaws (5) are, which reduces the free buckling length (X) even further. <IMAGE>

For this purpose, the invention provides for control by two electronic switches, on the one hand by positive pulses and on the other hand by negative pulses, positive and negative pulses following one another in time being provided in pairs. The electronic switches are connected to a resistance network which is connected to reference potential via a first capacitor and to the coaxial cable via a second capacitor. The pulse stage can be advantageously used for transmitting phase-modulated pulses via coaxial cables. <IMAGE>
Patent DE-3114046-A1 (DE)
Title: Regulating device
Inventor: OEHLUND ALF
IPC: B08B15/04
Filed: 1981-04-07
Abstract: In electric welding with covered electrodes, a device is previously known for automatic regulation of the slide of a spot exhauster provided for smoke extraction. The device is provided with a control cylinder for the slide. It is desirable to be able also to automatically regulate the slide of a spot exhauster in connection with gas welding or gas cutting. This is achieved with the present invention owing to the fact that the control cylinder, designed as a pneumatic single-acting cylinder with spring return, is connected to the pressure side of a gas tank in a welding or cutting unit and with its piston is under the effect of the gas pressure, so that the slide is held in its closed position against the action of the restoring spring as long as the welding or cutting operation is running, and opens or closes the slide as a function of the pressure change occurring at the start or end of a welding or cutting operation.

Title: Emergency call device for the roof car of an external lift
Inventor: GUENTHER HANS
IPC: B66B5/00
Filed: 1981-05-12
Abstract: The invention relates to an emergency call device for the roof car of an external lift, in which a 4- pin or 5- pin socket installation, which originates from a mains connecting switch and is laid on the building roof, is provided for the 3-phase AC supply of the roof car, which car is connected via a line to one of the sockets and has the devices required for the operating movements, including the electrical switches, upstream of which a main contactor is connected. In order to avoid having to provide more conductors for such an emergency call device that are necessary for the power supply to the roof car, it is proposed that a capacitor (C1) be connected as a reactive current source upstream from the main contactor (KO) between the conductors (L1 and L2), via an opening contact of the main contactor (KO), and that, to detect the currents, a differential current measurement relay (F2) be connected into the conductors (L1 and L3) between the mains connecting switch (F0, F1, Q0) and the socket installation (SA) and a voltage measurement relay (F4) be placed between one of the conductors (L1-L3) and the neutral conductor (N), the relays (F2 and F3) closing the emergency call device circuit (ZLT) in the case of a current difference in the 3-phase network, which is loaded symmetrically during operation, and the relay (F4) closing the emergency call device circuit (ZLT) in the case of a voltage drop, while correspondingly linking the individual relay contacts. <IMAGE>

The forging tools (2, 3) execute a circular motion and advance the forged stock (1) in steps for as long as they are in contact with the latter, i.e. along part of their circular path. <IMAGE>
Patent DE-3126118-A1 (DE)
Title: Price-tag
Inventor: KRAUSE HANS-JUERGEN
IPC: G09F3/00
Filed: 1981-07-02
Abstract: The invention aims to further develop a price-tag, such as is required in food shops, butchers', snack bars inter alia for the sale of salads, goods containing vinegar or the like from open storage vessels. There is a requirement for each storage vessel to be allocated a tag indicating the price. However, this proves problematical, since frequently the necessary space to place the tag is absent and, in addition, price-tags of this type easily slip from their intended position and thus lose their clear assignment and function. To solve this problem the invention proposes that the price-tag form a unit with the handle (3) of a scoop (2), while, at the same time, preserving the external shape of the scoop. These are scoops which, in any case, have to be made available for selling goods in this way. The price-tags can be designed in many different ways, in particular as a printed self-adhesive film (1) inter alia. With the proposed solution, indicating the price in a space-saving and checkable manner is possible. <IMAGE>

Title: Tape drive system for recording and replaying video signals in both directions of tape movement in accordance with the helical track method
Inventor: MANGOLD HANS DIPL ING
IPC: G11B15/665
Filed: 1981-08-14
Abstract: A simple but accurate transportation of the video tape in both directions of movement without position changes and a simplified manufacturing process of the tape drive system is achieved in accordance with Figure 1 by the fact that the two capstan shafts (8, 18) driving the magnetic tape (27) in the forward or reverse direction of movement are connected with variable direction of rotation by at least one common belt (26). Each direction of tape movement is associated with different tape guide elements (3, 4, 11; 19, 22/6, 13; 15, 17, 23) and tape sensing elements (9; 20/10; 21) which are arranged on in each case one of two associated planes (A, B), which are inclined relative to one another, of an assembly plate whilst the head drum (25) is arranged on a third plane (C) inclined relative to the first (A) and second (B) plane. The invention results in an extension of the recording time of a reversible cassette and keeps down the component expenditure in the equipment, particularly due to the fact that the second drive shaft is not driven by an additional drive motor but by the first drive shaft via a common belt drive. <IMAGE>

Patent DE-3144260-A1 (DE)
Title: Electrical beam balance
Inventor: STADLER EBERHARD DIPL PHYS
IPC: G01G21/24
Filed: 1981-11-07
Abstract: In high-definition electrical balances, for example on the principle of electromagnet force compensation, there is often the wish to have the possibility of checking and readjusting the sensitivity of the balance by means of an incorporated calibration facility. Instead of using an incorporated connectable weight for this, the invention proposes, where beam balances are concerned, to make direct use of the transmission beam. This transmission beam is of asymmetric design and normally counterbalances the empty load pan and the load receiver (Figure 1). By use of a special design of the coupling member between the load receiver and transmission beam, the transmission beam can be separated from the load receiver in a calibration position and, as a result of its asymmetry, exerts on the force-compensation system a specific force which is used for calibration. <IMAGE>
