Patent DE-3232575-A1 (DE)
Title: Electric motor-driven knife
Inventor: KRAH KLAUS
IPC: B26B7/00
Filed: 1982-09-02
Abstract: Electric motor-driven knife, in particular for cutting foodstuffs, having a housing which possesses a handle and is intended for accommodating the drive motor and holding devices for at least one knife blade, and having a switching member for opening and closing the circuit for the drive motor. To prevent unintentional actuation of the switching member, the switching member is mounted moveably in the housing in such a way that, in a first partial movement, it can be conveyed only into a position of readiness, from which, in a second partial movement, it is conveyed into the end position closing the circuit of the drive motor. The switching member can be mounted in the housing of the electric motor such that the user can perform successive partial movements of the switching member, these partial movements having opposite directions of rotation.

Title: Gritting device for installation in a motor vehicle
Inventor: MEYER WILHELM
IPC: B60B39/10
Filed: 1982-11-06
Abstract: The invention relates to a device for reducing the risk of skidding, i.e. for preventing the wheels of a motor vehicle blocking on smooth or iced-up carriageways. For this purpose, an electromechanical gritting device which can be actuated via a switch arranged in the region of the driver's seat, preferably by means of an operational switch and a switch coupled to the foot brake of the motor vehicle is arranged at least in front of the front wheels of the motor vehicle. When the switch is actuated, sand, preferably dry, fine quartz sand, which is located in a container in the gritting device is scattered in front of the wheels, even small amounts of the gritting material being sufficient to prevent the vehicle leaving the carriageway when the carriageway is covered in ice or smooth. In addition, in front of the outlet opening in the container a chamber can be provided having a chamber opening which is directed towards the container and with an opening directed towards the outlet opening, in which chamber at least two chamber containers which can be rotated about an axis are arranged.

Title: Method and device for piecing a thread in an open-end spinning apparatus
Inventor: LOVAS KURT
IPC: D01H4/48
Filed: 1982-12-18
Abstract: In the piecing of a thread (3) in an open-end spinning apparatus, the thread (3) is returned to the open-end spinning apparatus as a result of the reverse rotation of a bobbin (33) and of a pair of auxiliary rollers (21). After the completion of the return, the thread (3) is released from the pair of auxiliary rollers (21) and, until the normal spinning draw-off commences, is subjected to an auxiliary draw-off at a greater distance from the open-end spinning apparatus than this spinning draw-off. This auxiliary draw-off can take place solely by means of the bobbin (33) or also independently of this. The generation of this pulling force is effected by an auxiliary draw-off device (33) which is arranged at a greater distance from the open-end spinning apparatus than the pair of draw-off rollers (13). <IMAGE>

IPC: F27B15/08
Filed: 1982-12-29

Title: Process for the preparation of a lustrous carbon former for foundry applications
Inventor: GAROT MAURICE ING GRAD
IPC: B22C1/02
Filed: 1983-02-17
Abstract: A process for the preparation of a lustrous carbon former for foundry applications, based on polystyrene, is described. The polystyrene is homogeneously melted at temperatures of 200-280 DEG C with at least one other lustrous carbon former from the group comprising the pitches, bitumins, oils, natural resins and synthetic resins. The material thus obtained can be cooled and coarsely comminuted and then milled in conventional milling units to a particle size below 0.7 mm, which is not possible with an untreated polystyrene. Moreover, the material remains free-flowing even at relatively high temperatures (for example up to 60 DEG C) even if large amounts of another lustrous carbon former having a low softening point are used. In the case of other lustrous carbon formers from the group comprising the pitches, bitumins, natural resins and synthetic resins, their total amount is 10-90% by weight, preferably 20-40% by weight, relative to the finished product. Other lustrous carbon formers from the group comprising the oils are used in an amount of up to 40% by weight, preferably up to 25% by weight, advantageously as a mixture with a lustrous carbon former from the group comprising the pitches, bitumins, natural resins and synthetic resins.

Patent DE-3322152-A1 (DE)
Title: Method and circuit arrangement for operating terminals of a digital subscriber line
Inventor: KRAUTKRAEMER WILLFRIED DIPL IN
IPC: H04L12/10
Filed: 1983-06-21
Abstract: If a plurality of terminals which are fed by a power supply device is connected to a digital subscriber interface at the subscriber end, the transmission of the data and the power feeding occurring via a multi-wire dataline and an additional power feed being provided from the exchange via the subscriber line which is sufficient for supplying only a single terminal, the polarity of the power feeding voltage is reversed and dropped to a lower value by the subscriber-end subscriber interface when the power supply device fails. The polarity reversal is used for signalling emergency operation and the lower voltage value indicates the idle position. As soon as a terminal is involved in an outgoing or incoming connection, the power feeding voltage is raised to the normal value in order to prevent the remaining terminals from establishing a connection in this manner. This ensures that only one device is always involved at the same time in an outgoing or incoming connection since the line feed from the exchange is only sufficient for supplying one single terminal.

Title: Circuit for the East-West pincushion correction in a colour television receiver
Inventor: KRAUS HEINZ DIPL ING
IPC: H04N3/27
Filed: 1983-09-01
Abstract: In the case of a colour television receiver having horizontal and vertical generators which can be switched over to various horizontal and vertical frequencies and having a circuit for the East-West pincushion correction, in which a vertical-frequency sawtooth voltage is fed after integration in an integrator to an amplifier which emits a vertical-frequency, parabolic correction voltage, modulating the amplitude of the line deflecting current, the East-West correction circuit is intended to be switchable in dependence on the respective horizontal and vertical deflecting frequencies. According to the invention, the a.c. voltage amplification of the amplifier for altering the correction amplitude and its operating point for altering the line amplitude is set optimally to the higher-frequency operating mode of the colour television receiver. If the same a.c. voltage amplification is retained with the lower-frequency operating mode, the vertical-frequency sawtooth voltage picked off from the vertical generator is lowered by such a factor that the amplitude of the parabolic correction voltages is of the same magnitude in both operating modes.

Title: Measuring device for an adjustable tool of a numerically controlled machine tool
Inventor: BECK HANS-WERNER
IPC: G05B19/401
Filed: 1984-03-07
Abstract: A measuring device of an automatic adjusting device for a tool of a numerically controlled machine tool is described. Two sensors designed as electric transducers are provided, of which the first detects the position of the tool and the second detects the position of a reference surface. If the distance measured by the two sensors deviates from a predetermined desired difference, an analysing circuit transmits a signal to the adjusting device in order to move the tool into the desired position. However, even when the tool is in its desired position, the machined surface of the workpiece can deviate from the desired size. A third sensor is therefore provided which senses the position of the machined surface of the workpiece and as a function of this accordingly adjusts the "zero balance position" of the other two sensors, i.e. re-establishes the desired difference (Figure 1). <IMAGE>
