Title: Spray-washer handling workpiece prior to varnish or coating routines
Inventor: HESTERMANN GERHARD
IPC: F04D15/00
Filed: 1996-03-13
Abstract: The collecting channel acting as chamber base has separate outlets at the same level for the several fluids as linked via pipe to the respective collecting container closed off by individually controlled plate valves (1.42,1.51,1.61). A suction chest (4.0) above the container or its fluid level has a suction orifice in each case linked via immersed suction line (4.3) to the respective fluid container (5.1-5.3) and closed off by individually controlled plate valves. The intake side of a pump unit above fluid level is connected by means of a gradient suction line (3.2) joined to the suction chest above the lid level. A pressure line (2.4) connects the pump to the sprays ringing the workpieces (2.1,2.2). Between a pressure line valve (2.3) and the pump delivery side is a pipe connection with adjacent controlled valve (6.0) linked by line (6.1) to the vacuum container (6.2). This fills the idling pump with the first fluid to be sprayed out, with line (2.4) valve (2.3) open and vacuum line valve (6.0) accordingly closed.

Title: High speed thread spool winder, used in winding of cross wound spools
Inventor: DAMMANN PETER
IPC: B65H54/28
Filed: 1996-03-29
Abstract: An appts. for winding thread has a thread guide (4) which undergoes movement along a traversing stroke and a parallel rotating grooved roller (1) which follows the guide as the thread runs and which has a thread-guiding groove (2) in the end regions of the traversing stroke. The roller rotation speed is so synchronised with the guide traversing movement that the thread (8) running from the guide consistently runs in the guide grooves.  The grooved roller has two end regions, each (1a, 1b) with a guide groove and each being able to be displaced axially w.r.t the other (1b, 1a) to produce an alteration of the traverse stroke length within the limits of a max. and a min. stroke.  Also claimed is a method producing wound spools from thread via double traverse implemented by the appts.  Pref. the stroke of the thread guide is adjusted synchronously with the axial adjustment of the end regions. The thread guide at the stroke end and the guiding groove are in a plane normal to the grooved roller or the groove can be offset from the normal plane at stroke reversal. The end parts are cylindrical tubes which are located securely against rotation on a common roller on which they can be axially adjusted, or each part has fingers parallel to the axis facing towards the other and interlocking tightly with those of the part opposite.

Patent DE-19636753-A1 (DE)
Title: Semiconductor drive circuit for control of load e.g. motor
Inventor: FUKUNAGA MASANORI
IPC: H03K17/06
Filed: 1996-09-10
Abstract: The drive circuit (1000) includes a control circuit (HD10) connected to a current source (16), an impulse generator (1), and a pair of power transistors (17,18). The transistors e.g. IGBTs, are arranged in a bridge (19) coupled totem pole fashion between main voltage supplies (VDD,GND). The potential of node points (N1) of the two transistors act as a reference to control one power transistor (17), this transistor being in a conducting or non-conducting state depending on ON or OFF signals from the impulse generator.  A level shifting circuit (2-9) shift the ON-OFF signals from the impulse generator to the potential sides of the node point. Provided with the shifting circuit are two HNMOS transistors (2,3), for level shifting, which have breakdown characteristics greater than voltage difference between the two main voltage supplies. The control circuit has a control signal output circuit (10A), e.g. an SR flip-flop, and a protection circuit (27). The protection circuit, e.g. a logic circuit, continuously provides a predetermined control signal to the output circuit so that the last signal is provided continuously if the two level shift signals are applied simultaneously.
