Patent DE-4343873-A1 (DE)
Title: Marking the thread end on filled spools
Inventor: HUTTER HANS-GERHARD
IPC: B65H63/00
Filed: 1993-12-22
Abstract: A method for marking a thread end after a spool winding process entails winding off a limited length of thread. A marking strip is placed on the spool surface and, after rewinding begins, is partly covered by the thread end. This is achieved here by a peg (7) revolving about the spool axis (33), parallel to it and interposed between spool surface and thread suction take-off (6). The peg is revolved several times in contra-direction to the spool rotation (12) to form a multi-winding thread layer. After the marker tape is laid on the spool surface, the peg is revolved in reverse.  Also claimed is an appts. having a pin (2) to take the spool (3) and a winding wheel (8) consisting of at least one or several winding pegs (7) distributed on the circumference at a radial distance from the spool surface and parallel to the spool outline. Wheel and spool are on coaxial bearings. In textile spooling. For smaller spools a previous soln. of marking and overwinding by withdrawal of the thread from the suction take-off has been successful but, for spools from 500 mm dia., a length of some metres has to be retrieved, sometimes leading to severe entanglement. The present soln. eliminates this disadvantage.

Patent DE-4412962-A1 (DE)
Title: Image-producing apparatus (device)
Inventor: MAKIURA TAKASHI
IPC: B41J29/00
Filed: 1994-04-14
Abstract: The invention serves the purpose of preventing silicone gas produced in a fixing unit (42) from flowing into a charging device (34). When a charging device (34) produces a corona discharge, a so-called corona wind rises, and air is thereby sucked into an outer air inlet (52). The air flows through an air duct (54) and an air inlet (53) to the charging device, and it flows out as a stream of air through a front opening (45). Silicone gas is separated by the stream of air, and this prevents said gas from penetrating into the charging device.   <IMAGE>

Patent DE-4418328-A1 (DE)
Title: Vehicle flasher indicator light resetting device
Inventor: ENGELHARDT MARTIN
IPC: B60Q1/42
Filed: 1994-05-26
Abstract: The invention concerns a reset device for a blinker switch. Prior art blinker switches of this kind are usually fitted with a pivoting resetter with two lateral arms acted on by opposed springs which extend through the switch housing from one side to the other. These springs not only bias the resetter (9) towards the steering-wheel shaft but also produce a torque which tends to bring the resetter back to its central position. To eliminate the known tension springs, the invention calls for a single compression spring which acts on the resetter and which provides both a force in the direction of the longitudinal axis of the resetter and the required reset moment.

Patent DE-4422820-A1 (DE)
Title: Electrical discharge machining unit
Inventor: MAGARA TAKUJI
IPC: B23H7/04
Filed: 1994-06-29
Abstract: An electrical discharge machining unit for machining a workpiece by applying a voltage to a working gap which is formed between an electrode and the tool has a direct-current power supply for delivering a working current and a current limiter which is connected in series with the direct-current power supply in order to limit the working current. A switching device is connected in series with the direct-current power supply as well as with the current limiter and can be operated in such a way that it makes a voltage available to the working gap and forms a direct-current pulse. A series circuit consisting of an inductance and a capacitor is connected in parallel with the working gap. The purpose of the series circuit is either to suppress the interruption in a direct-current-pulse current component which follows a capacitor-discharge current component, as a result of which a pulsed-current phenomenon is prevented from occurring, or to suppress the continuation of a direct-current-pulse current component, in particular of pulses, which follows a capacitor-discharge current component. Irrespective of whether the final machining is to have a mirror quality, values for the capacitance and inductance for the series circuit can be selected within specified ranges.

Title: Picture frame
Inventor: KOEHLER HINRICH DIPL ING
IPC: A47G1/06
Filed: 1994-10-18
Abstract: Easels have served hitherto merely for setting the height and fixing of the painting ground by clamping the same in relation to the working position of the artist. The new easel permits, over and above this fixed adjustment of the working height of the painting ground, a high degree of mobility, i.e. variability of the position of the painting ground in relation to that of the artist. Moreover, individual easels of this type can be used to build up, in a modular construction, large-size easels in principle of the same type. This new type of easel constitutes a universal working framework in respect of its extendibility and mobility. By providing a plate with nubs in accordance with a specific pattern, a surface is produced onto which in particular wedge frames in the commercially available side widths can be clamped. The height positioning of the painting ground is achieved by simply inserting the clamped-on wedge frame in a different position. The same effects are achieved by providing the surface of the plate with at least triangular holes and corresponding clamping-on aids; magnetisable plate surfaces forming a unit with appropriate clamping-on aids are also suitable; plates provided with needles serve the same purpose. The plate is mounted centrically on a stationary background; at the same time, it remains freely movable about its own axis. By means of bores at a radial distance from this centric guide in the ...
