Patent DE-4303573-A1 (DE)
Title: Sealing system with primary and secondary seals
Inventor: BURKAMP WERNER
IPC: E06B5/16
Filed: 1993-02-08
Abstract: In the case of devices for closing off rooms, the gap which usually remains between frame and leaf forms a problem location. This problem location protects, usually to an insignificant extent, a peripheral primary seal, such as a lip seal. It ensures that the door closes softly, often against an abutment step, and insulates against draughts. In the event of flames, this seal is, however, unsatisfactory because it burns immediately, with the result that the gap provides a welcome opening for smoke and flames. The intention is to close off said gap with respect to flames and smoke. For this purpose, the invention proposes a sealing system with fire protection for devices for closing off rooms (1, 2), such as windows, doors, in the case of which sealing system, a primary seal (10; 10a, 10b, 10c) and a secondary sealing (20; 20a, 20b, 20c) are arranged in the frame (1) of the closing-off device (1, 2); the two seals (10; 20) are aligned essentially perpendicularly with respect to one another in order - in the event of a fire - to exert force and provide sealing on the end side and on the region - coming to bear against the frame (1) - of the leaf (2) of the closing-off device (1, 2). <IMAGE>
Patent DE-4306095-A1 (DE)
Title: Spinning and winding installation - has electronic data processing to enable first quality spun yarn to be wound with priority
Inventor: MEYER URS DR
IPC: D01H13/32
Filed: 1993-02-27
Abstract: Control of a spinning installation which has a ring spinning frame and associated machinery is effected by means of a service robot, which is provided with equipment to store data relative to the package being processed on the frame. This information is utilised in the following stages. The appts. is also claimed. The ring spinning frame (RSM) has a series of working positions (1-20), and each has a supply of rovings with a flow control (LK). The cops are transferred after doffing to the cop trays (PT) by the service robot (BDA), which travels along the spinning positions, keeping a record of the time and relevant details during build of the cop. This information is stored as electronic data in semiconductor devices, which is transferred at the headstock (EK1) into a controller (MS) which also serves as the machine control. The cop trays (PT) on a conveyor (PTFS) then proceed to an initial stage (KB) on the yarn winding machine (SPM), where imperfect cops can be seaparated for further treatment. The first quality yarn is delivered directly into the winding units (SS) with empty tubes being returned to the spinning frame in the enclosed system (PTFS). The yarn may require some treatment at the clearers (GR) as it is wound on the reel. This treatment is also recorded electronically in the module (NW2) which works in conjunction with the micro processor (PLR). The winding machine is controlled from these units through a controller (SSP). The feedback of information enables reels of a first quality yarn without broken ends, thick and thin places etc. to be produced. There is also continuing improvement, as the cause of faults is traced back to previous stages. ADVANTAGE - Faults are related to processing stages, which may have caused the fault, and enable causes to be rectified promptly, which leads to overall quality control, and an improved quality of yarn.

Title: Speed-related ignition for two-stroke IC engine of power tool
Inventor: TROST JUERGEN DR ING
IPC: F02B75/02
Filed: 1993-12-16
Abstract: The magnet wheel (1) rotating with the crankshaft has a magnetised sector (2) which induces a voltage (U1) in a fixed induction coil (3) wired in series with a resistor (R1) and capacitor (C1). When the voltage (U2) across the capacitor attains a preset threshold level, a switching circuit (5) generates a spark at the plug (6) in the combustion chamber. The threshold is set by the basic delay of the low-pass series circuit (4). A parallel capacitor chain (C4, C5) switched by a transistor (T2) causes the delay to increase with steepness of induced voltage. At a preset max. speed another transistor (T3) conducts, deactivating the parallel chain.

Title: Method and circuit for improving the short-circuit stability of a bipolar IGBT
Inventor: CHOKHAWALA RAHUL S
IPC: H03K17/082
Filed: 1994-03-29
Abstract: A circuit for improving the short-circuit stability of an IGBT (12) uses a MOSFET (14) which reduces the voltage fed to the gate electrode of the IGBT during a short-circuit state when switching on, as a result of which the short-circuit current flowing through the IGBT (12) is reduced. A Zener diode (13, 15) is connected between the MOSFET (14) and the gate electrode of the IGBT (12), in order to clamp the voltage of the gate electrode of the IGBT at a predetermined voltage when the MOS transistor is switched on during a short-circuit state. The MOSFET is switched on if the voltage at the collector of the IGBT rises during a short-circuit state. If the fault is of transient type, then the circuit resets the normal gate voltage. The circuit draws only a small current from the gate driver and requires no separate DC voltage source, so that the circuit can be inserted into IGBT modules or used as an interface between the gate driver circuit and the gate electrode. <IMAGE>
