Patent DE-3624232-A1 (DE)
Inventor: MANSCHITZ ERWIN
IPC: B23B31/12
Filed: 1986-07-18
Abstract: A chuck for receiving and holding the shank of a drilling tool includes a chuck member with a central bore. An anvil for transmitting axially directed percussive force extends into a rear end of the central bore. Clamping jaws are movable in guide channels formed in the chuck member extending into the central bore ahead of the anvil for frictionally locking the shank. In the region of the chuck member into which the anvil is located, there is a radially extending passageway through the chuck member extending between the central bore and a guide channel. A retaining member is radially displaceable through the passageway and has a dimension so that it can project outwardly or inwardly from the passageway. When the remaining member extends radially inwardly from the passageway, it can seat within an annular groove in the anvil and hold the anvil in a position so that it does not transmit percussive force. If the retaining member extends radially outwardly from the passageway, it can seat within a groove in a clamping jaw and secure the clamping jaw out of frictional contact with the shank.

Title: Support element for shifting supports
Inventor: KAUP OTMAR
IPC: B66F9/14
Filed: 1987-03-11
Abstract: For supporting a body on another by means of a support element which permits sidewards shifting under load, a configuration of the support element is sought that allows it to be manufactured inexpensively. To solve this problem, the support element has a metal part 45 consisting of a sheet-metal part whose edge is bent over to form a claw part 6, with the element permitting shifting under load being a plastic plate 8 which encloses the metal part 5 at two opposite sides lying in the direction of movement. With only two components, namely the metal part 5 and the plastic plate 8, a support that can be shifted under load is thus made possible, with both parts being easy to manufacture. The support element is used preferably for the parts that can shift sideways under load of a side loader on the front attachment of a fork-lift truck. <IMAGE>

Patent DE-3716060-A1 (DE)
Title: Modulator for generating a frequency-shift-keyed RF signal
Inventor: LOGEMANN JOERG DIPL ING
IPC: H04L27/12
Filed: 1987-05-14
Abstract: To generate a frequency-shift-keyed RF signal (F1 modulation) with a narrow spectrum, a numerically controlled oscillator is controlled by a bivalent modulation signal with the intermediate connection of a counter and a read-only memory. When the modulation signal is shift-keyed, the counter runs up or down through its counting range and stops at the counter reading until the next shift keying. The counter output signal addresses the read-only memory which reads out from a stored table an oscillator control value assigned to the address value with which it controls the oscillator. The spectral width can be significantly reduced through non-linear allocation of the control value to the address value. A plurality of different selectable tables are preferably stored in the read-only memory.

Patent DE-3717921-A1 (DE)
Inventor: BUTZHEINEN KARL-HEINZ DIPL ING
IPC: D02G/
Filed: 1987-05-27
Abstract: In the case of yarns consisting of at least two basic yarns bounded together by a hot-melt adhesive yarn, it is difficult to achieve satisfactory bonding while maintaining the required yarn properties. In particular, this type of yarn requires very strong twisting. To overcome these drawbacks, it is proposed that the basic yarns consisting of multiple thread filament yarns are swirled with at least one multiple thread adhesive yarn, so that as a result of the formation of loops and curves along the yarn cross-section during swirling, strong bonding is obtained together with other excellent yarn properties.

Title: Device for detecting mis-shunts in railway shunting systems
Inventor: JUNG MARTIN ING GRAD
IPC: B61L25/02
Filed: 1988-05-02
Abstract: As vehicle axles enter or leave the zone of operation (WZ2) of a distribution railway switch (W2) it is tested whether the actual position of the railway switch corresponds to the set position. This set position results from the group code which is allocated to the section of train passing through the railway switch, if deviation is detected between the set position and actual position of the railway switch, the section of train is a mis-shunt. A mis-shunt is allocated a mis-shunt detection (L) which is passed on to the controls of the subsequent distribution railway switches and to the sorting siding into which the mis-shunt is running. The mis-shunt detector causes the track sections and the sorting siding which is respectively occupied by the mis-shunt to light up and thus permits the mis-shunt to be followed and located in an optimum way. <IMAGE>

Title: System for exposing the lower half of the face to fresh air as a stimulus for keeping the vehicle driver alert
Inventor: BROSIG EGBERT
IPC: B60R22/00
Filed: 1988-07-09
Abstract: The invention relates to a ventilation system for the interior of a car, which comprises fresh-air nozzles or blowers and with which the driver especially is intended to be, and can be, kept alert and awake. The particular feature is that nozzles or blowers are fitted in a sliding manner on the seat belt over the chest of the driver and blow in the direction of the lower half of the face (chin, mouth and nose) where experience shows that this stimulus for keeping the driver alert has the greatest effect. In order further to increase the stimulating effect of the flow of fresh air, a small scent container can be connected to the air supply or to the nozzles/blowers and this (for example when pressed with the hand) gives off a small amount of scent into the flow of air.
