Title: Circuit arrangement for overcurrent limiting in an invertor having power semiconductors, for example GTO thyristors, which can be turned off
Inventor: TADROS YEHIA DR ING
IPC: H02H7/122
Filed: 1985-12-12
Abstract: In the case of an invertor, the series circuit of two GTO thyristors (T1, T2) with a circuitry inductor (LS) is located between the two DC voltage potentials of said invertor and the AC voltage connection is arranged in the connection of the two GTO thyristors (T1, T2). The series circuit of a circuitry capacitor (CS) with a first circuitry diode (DS1) is connected in parallel with the one GTO thyristor (T1). A device which absorbs the excess circuitry energy is connected in series with a storage capacitor (C0) between the DC voltage potentials of the invertor. In this case, the one pole of the storage capacitor (C0) is connected via a second circuitry diode (DS2) to the connection between the circuitry capacitor (CS) and the first circuitry diode (DS1). It is intended to prevent an overcurrent occurring in the event of erroneous, simultaneous triggering of the two GTO thyristors (T1, T2). For this purpose, the storage capacitor (C0) is decoupled from the DC voltage potential by a third circuitry diode (DS3) and a protective tuned circuit, consisting of a protection thyristor (TK1) which can be triggered immediately in the event of overcurrent, an inductor coil (LK2) and a precharged capacitor (CK), is connected in parallel with the invertor input. <IMAGE>

Title: Connecting rod for reciprocating piston machines with spherical segment-shaped guidance in the cylinder
Inventor: SCHIEBER GERHARD
IPC: F02F3/00
Filed: 1986-01-20
Abstract: The essential feature of the invention is that the connecting rod is guided in the region of the small eye itself in the axial direction in the cylinder. The piston then only has to assume the function of sealing and transmitting the force of the gas via the connecting rod to the reciprocating pin of the crank shaft. The guidance of the connecting rod in the cylinder is achieved according to the invention by spherical running face segments being connected in the oscillating plane of the connecting rod to the small connecting rod eye securely in the region of the said connecting rod eye so as to be concentric with respect to the bore of the connecting rod and have a small degree of play with respect to the cylinder bore.

Title: Combustion method
Inventor: SWOBODA WALTER
IPC: F23D11/40
Filed: 1986-06-05
Abstract: Combustion method and burner head for implementing the method for generating a stable flame which burns soot-free even in the case of the smallest oil quantities in the region of 1 kg/h with the slightest air excess extensively independently of the combustion space conditions, the primary air being supplied by means of a baffle plate of approximately 200-300 mm<2> free cross-section. The baffle plate is extended to form a mixing chamber which, together with a stationary part, forms a regulating device for the tangentially inflowing secondary air which flows in with a [lacuna] which is the same as or greater than that of the primary air. The secondary air forms a stabilising whirl which draws in the oil/secondary air mixture, brings about gasification and combusts in the flame pipe which follows. For further shortening of the flame, a deflector plate can be arranged in the flame pipe.

Patent DE-3632400-A1 (DE)
Title: Method and device for characterising condensable impurities on a surface
Inventor: NIESSNER REINHARD
IPC: G01N21/94
Filed: 1986-09-24
Abstract: A method is described for the detection of particulate impurities or impurities incorporated in the surface. The method is based on the role of the impurities as condensation nuclei for a supersaturation of a vaporisable substance, said supersaturation being generated by adiabatic expansion. A spectrum which is dependent on the size of the impurities can be recorded by program-controlled pressure build-up and, consequently, variably producible supersaturations. The nucleation centres which have grown to drop size can therefore be counted, for example, optically. Only certain particles capable of interaction with the substance are activated as condensation nuclei for a given supersaturation by selecting the physico-chemical properties of the condensable substance.
Patent DE-3634368-A1 (DE)
Title: Shape-imparting casting device for the continuous casting of flat stock from metal
Inventor: GROTHE HORST
IPC: B22D11/04
Filed: 1986-10-09
Abstract: To influence the shape of continuously cast flat stock by means of the shape-imparting casting device, e.g. a continuous casting mould 3 or a cooled pair of rolls or guide rollers, the opposing shape-imparting surfaces 10a, 11a of side walls 10, 11 are made adjustable in opposite directions transversely to the casting direction and provided with a slight S-shaped contour over their entire length such that the contours of the shape-imparting surfaces complement one another only in a certain neutral relative position of the surfaces in which, although the casting cross-section is slightly S-shaped, the thickness is uniform across the width. Changes in the contour of the surfaces of the strand produced which occur subsequently in the course of secondary cooling, caused for instance by differing solidification processes, are however avoided by moving the shape-imparting surfaces or the side walls on which they are supported out of the neutral relative position so that the casting cross-section is narrowed either in the centre or at the edges in a presetting operation. <IMAGE>

Title: Commutator-less DC machine control-drive - using control-regulation unit to generate square-wave current blocks position amplitude and duration and set-point signals
Inventor: HUSSELS PETER DR ING
IPC: H02P25/024
Filed: 1987-07-29
Abstract: The control-drive for commutatorless d.c. machine is based on impressing square-wave current on the phase windings of the d.c. machine. The position, amplitude and length (duration) of the blocks of square-wave current are generated in the control-and-regulation unit (S) as set-point signals, which are then used to form the signals (Z) for controlling (driving) the inverter (W) switch. The machine torque is adjusted by means of positional adjustment of the current blocks length. The converter is released at partial load and idling only for short time periods (e.g. current block length Ti), phase-synchronously relative to the rotor movement. USE/ADVANTAGE - For inverter driven commutator-less d.c. machines. Fast rise time for current blocks achieved.

Title: Rotary slide valve for hydraulic power-assisted steering systems
Inventor: ELSER DIETER
IPC: B62D6/02
Filed: 1987-11-25
Abstract: In the case of known rotary slide valves the reaction devices require a relatively large amount of axial structural space, and the reaction pressure can only be varied within narrow limits. In the novel arrangement the intention is to integrate the reaction device in the rotary slide valve in a simple manner and for it to be possible for the reaction pressure to be varied within a wide range. The intention is furthermore for the reaction device to respond in a precise manner. The reaction pistons (36) are guided in radial holes (34) in the rotary slide valve (12) and are supported via rolling elements (40), under loading by centring springs (35), on roof-shaped sloping surfaces (38) of the valve sleeve (13). The radial holes (34) which contain the reaction pistons (36) are connected to a high-pressure pump via a feed hole (42) and an annular groove (55). A concentric axial hole (43) contains a piston (50) which can be actuated by an electromagnet (52) and which can change the reaction pressure. The piston (50) also contains a cut-off valve (44A) for limiting the reaction pressure. The rotary slide valve (12, 13) is accommodated in a separate valve casing (11) and is suitable for mounting on a steering-system casing. <IMAGE>
