Patent DE-3730649-A1 (DE)
Title: Circuit arrangement having at least one series circuit of two transistors
Inventor: ZORN RUDOLF DIPL ING
IPC: H03K17/687
Filed: 1987-09-11
Abstract: Circuit arrangement having at least one series circuit of the switching junction of a first transistor (11) in an emitter or source circuit, and a second transistor (8) in an emitter-follower or source-follower circuit. The aim of using the transistors (8, 11) is optionally to connect an output present at the tie point of the switching junctions to one of two feed inputs (2, 6). In order to prevent the two transistors (8, 11) from becoming conductive simultaneously, a third transistor (10) is provided which is driven together with the first transistor (11) and which applies a blocking potential in the turned-on state to the second transistor (8). The circuit arrangement can be used with particular advantage to control motors. <IMAGE>

Patent DE-3822910-A1 (DE)
Inventor: HERZL PETER J
IPC: G01F1/84
Filed: 1988-07-06
Abstract: In a mass flowmeter of the Coriolis type the fluid to be metered is conducted through a pipe which is coiled to form a double loop 10,11. The pipe is anchored at its inlet and outlet ends and also at its center C which is the junction of the two loops to define a tuning fork in which the identical loops on either side of the anchored center function as tines that are free to vibrate as well as to twist. An electromagnetic driver 16 mounted at the vertex of the double loop is electrically energized to cause the loops to vibrate in phase opposition at the natural frequency of the tuning fork. The fluid passing through the double loop is subjected to Coriolis forces, thereby causing the vibrating loops 10,11 to torsionally oscillate in accordance with the mass flow of the fluid. Capacitance sensors 18,19 are symmetrically mounted on the respective loops to yield signals having a difference in magnitude and phase that depends on the amplitude of the torsional oscillations, these signals being applied to a differential amplifier 22 whose output is proportional to the mass flow of the fluid. <IMAGE>

Abstract: To reduce the pollutants (NOx and CO) in the exhaust gases from combustion, a method for burning liquid or gaseous fuels in which a mixture consisting of fuel and primary air and secondary air are supplied for the combustion process, a proportion of the exhaust gases formed during combustion is mixed in with the primary air and a proportion of the fuel is mixed in with the secondary air. A device for carrying out this method comprises an exhaust branch line (13) which branches off from the exhaust duct and opens into the burner chamber (3) of the burner (1) together with the primary air duct and the fuel supply line (10) and a fuel branch line (15) which branches off from the fuel supply line (10) and opens into the secondary air stream (12). In the case of a fan-operated burner (17), the fuel supply line (10) can emerge in the primary air duct (11), which, in a central region (18), carries the mixture consisting of primary air and exhaust gas and, in its peripheral region (19), carries a mixture consisting of secondary air and fuel. <IMAGE>

Title: Beaming machine for the selective assembling and warping of textile thread groups
Inventor: ALDER GUENTER
IPC: D02H5/00
Filed: 1989-01-10
Abstract: Beaming machines serving for the selective assembling and warping of textile thread groups are provided with a winding beam drivable at an adjustable rotational speed, with a transport mechanism preceding the latter and consisting of a drivable transport roller (6) and a top roller (5) capable of being lifted off from this and with a regulating roller (4) arranged between the transport mechanism and the winding beam on a pivoting arm (9) and to be pressed against the thread group to be assembled which runs past. So that the mechanical outlay can be reduced and higher warping speeds achieved, for warping to be performed the drive (8) of the transport mechanism is to be stopped and the top roller (5) is to be brought into a warping position which is sufficiently remote from the transport and regulating rollers (6 and 4) and makes it possible to guide the thread group (7a) to be warped directly to the winding beam (3a) and in which it cooperates as a measuring roller with a regulating device (17, 20, 21) controlling the winding-beam drive (2). <IMAGE>

Title: Method for manufacturing flat components
Inventor: KUHN RAINER DIPL ING
IPC: B21D26/02
Filed: 1989-03-04
Abstract: The method specified in Patent Application P 3840939.9-14 is to be improved according to the invention such that not all of the projections, especially narrow radii and sharp-edged profiles, are realised exclusively by a fluid-shaping method. The solution according to the invention consists in superimposing a mechanical deformation on the fluid-shaping method. The advantages obtained by the invention consist, in particular, in that even complicated shaped parts made of sheet metal can be produced in the final form in one working operation, i.e. even when, for example, narrow radii exist, subsequent shaping - in a further working station - is not necessary. Furthermore, an improvement in the product is to be noted, since all of the deformations occurring, whether in wide arcs or in narrow radii or in sharp-edged portions, can be optimally produced; all of the deformations are realised in one working step, each deformation being assigned the working method suitable for it. The less problematical deformations are formed by means of the fluid-shaping method, while narrow radii and the like are realised by additional, superimposed mechanical deformation. By proceeding in this way according to the invention, the deformation pressure for the fluid-shaping method can be reduced, which entails great advantages for the water hydraulics. In addition, the water pressure of the fluid-shaping process can perform a retaining function, which the ... Original abstract incomplete.

Abstract: The system is for generating electricity in space without release of water. A hydrogen-and-oxygen-burning gas generator 12, having a porous wall (36) (Fig.2) through which water may pass from a space 40, produces a steam exhaust. A turbogenerator 14, 16 is driven by hydrogen conveyed via lines 50a, 50c, 52, 50d, 58 to its turbine 16. The hydrogen is heated in a heat exchanger 20 by the gas generator's steam exhaust 60a which is subsequently condensed to water 60c in the heat exchanger 20 and a further condenser 22. The condensed water passes via a line 60c to a heat exchanger 23 to impart heat to liquid oxygen supplied via line 48a. The heated oxygen then passes via line 48b to the gas generator 12. A portion of the condensed water is passed via lines 60d, 60e and turbopump 24 to the gas generator which is cooled by injecting such water into the combustion region thereof. Any remaining (unused) water is passed via lines, 60f, 60g and a pressure regulator valve 26, to a tank 28. <IMAGE>
