Patent DE-3817652-A1 (DE)
Title: Electrically operated tractive unit with at least two drive systems
Inventor: STEIMEL ANDREAS DR
IPC: B60L9/30
Filed: 1988-05-25
Abstract: The tractive unit has at least two drive systems which each have at least one four-quadrant actuator (9, 17), an intermediate D.C. voltage circuit with intermediate circuit capacitor (12, 20) and a self-commutated power inverter (13, 21) for supplying at least one drive motor (14, 15, 22, 23) with variable voltage and frequency. The tractive unit is constructed as a multi-system tractive unit and can be operated universally on A.C. voltage or D.C. voltage of various levels, in which case respective regroupings of the individual power components are to be performed with the aid of switching devices (30 to 50). When A.C. voltage is supplied each four-quadrant actuator (9, 17) is connected to its own secondary winding (8, 16) of a transformer (4). When D.C. voltage is fed, each four-quadrant actuator (9, 17) is connected to the contact wire via the corresponding secondary winding (8, 16) of the transformer (4) whilst the corresponding primary winding (3, 5) is short-circuited. If the D.C. voltage is relatively high, the drive systems are connected in series on the input side whilst, in contrast, an input-side parallel connection of the drive systems is provided if a relatively low D.C. voltage is used. The suction circuits (10, 11, 18, 19) which are required for A.C. voltage operation are used as input filters for D.C. voltage operation. <IMAGE>

Title: Electrohydraulic directional control valve
Inventor: SCHUTTENBERG ECKARD
IPC: F15B13/044
Filed: 1988-07-16
Abstract: An electrohydraulic directional control valve (10) in a 4-way/4-position type of construction with a control spool (12) deflected by a single proportional magnet (14) against spring force is proposed in which the delimitation of the control area (25) of the control spool (12) from the fail-safe area (24) is carried out via the magnitude of the magnet current. A power increment (43) at the transition between the areas (25, 24) ensures that, despite the displacements of the characteristic which are caused by component tolerances, the control spool (12) does not leave the control area (25) up to a predetermined limit current value (41). Consequently, a displacement transducer with position feedback can be dispensed with at the directional control valve (12) itself. <IMAGE>
Patent DE-3824801-A1 (DE)
Inventor: BOEGNER KARLHEINZ DIPL ING
IPC: H01H51/06
Filed: 1988-07-21
Abstract: The proposal is for an electromagnetic switch for internal combustion engine starters with a magnetic core (2) and an armature (8) movable against the force of a return spring (17) on which the switching spindle (15) passing through the magnet core is secured, the end of said spindle facing away from the armature bearing a contact plate (22) co-operating with at least two electric terminals (25), in which there is, at the end of the switching spindle (15) facing away from the armature (8), an additional contact bridge (23) co-operating with at least two additional contacts (26, 27). When the switch is actuated, the appropriate starter is supplied via the additional contacts (26, 27) with a voltage ensuring the gradual rotation of the starter. This ensures the engagement of the starter pinion with a suitable toothed wheel, e.g. the flywheel of an internal combustion engine. It is only immediately afterwards that the main electric terminals (25) are electrically connected via the contact plate (22), thus applying the full supply voltage to the starter motor and taking it to maximum revolutions. Unsuccessful starting procedures which lay considerable mechanical stress on both the starter and the internal combustion engine are thus reduced to the minimum.

Patent DE-3832624-A1 (DE)
Title: Quick-clamping device for disc-shaped tools attached to the working shaft of an electric tool
Inventor: KRETSCHMAR PETER DIPL ING
IPC: B24B45/00
Filed: 1988-09-26
Abstract: In the case of a known device of this type, one of the flanges bearing on the tool is relieved of the clamping pressure for the tool by releasing rolling bodies which secure the flange against axial displacement on the working shaft and can move into an alternative space. The loosening torque for the clamping nut is in this case relatively large, as is the overall volume of the device. The new quick-clamping device is to enable a reduction of the loosening torque for the clamping nut and of the overall volume. Connected non-positively to the clamping nut (12) by means of interacting oblique faces are flanges (11, 26) which assume clamping and relieving functions, and the clamping nut (12) can be coupled to at least one of the flanges (11, 26) by means of a wrap spring (18). The latter prevents relative rotational movements, caused by axial forces, of the oblique faces corresponding to one another and held in a defined position relative to one another by means of spring force and can be loaded and unloaded with the aid of an adjusting member (20). <IMAGE>

Title: Self-starting synchronous motor
Inventor: WISTINGHAUSEN WALTER DIPL ING
IPC: H02K7/118
Filed: 1989-02-11
Abstract: The invention relates to a self-starting synchronous motor having a permanent-magnet rotor (7) which is mounted to come out with rotation play on the rotor shaft (10), between two limiting stops of a coupling component (12) which is arranged on the rotor shaft (10) and is to be driven by it. In order to make such synchronous motors suitable for relatively large drive powers as well, the coupling component (12) which is to be driven by the rotor (7) has a spring element (13) which stresses the rotor shaft (10), likewise with the interposition of a moulding (14), and forms the limiting stops, and whose friction torque with respect to the rotor shaft (10) on the one hand ensures the reliable transmission of the motor torque required in the operating mode but on the other hand results in the coupling component (12) sliding through on the rotor shaft (10) in the event of the movement energy occurring during starting of the rotor (7) and while it is being braked. <IMAGE>

Title: Pressure monitoring bolts in die casting machine - to ensure uniform pressure distribution over cross=section of machine
Inventor: HARTMANN BERND
IPC: B29C45/76
Filed: 1989-04-26
Abstract: Measuring device for recording the tensile stresses building up in the column of a pressure die casting machine consists of pressure bolts (24) arranged symmetrically in a base plate (25) fixed to a tension plate (12).  The series of both are symmetrical to the symmetrically located columns (16) and each bolt has a pressure transfer element (57) which conducts the moveable plate (13) when it is moved into a closing position towards the fixed plate (12).  The contact surfaces of the bolt (38) and the back surface are perpendicular to the central axis (18) of the machine. ADVANTAGE - A uniform stress distribution is assured as the electric signals from the pressure bolts are made equal by adjusting the nuts (22,23) at each end of the machine.  This leads to reduced wear on the measuring bolts and a longer work life.

Title: Use of N-(aminoacyl) amino-acids and salts - dopaminergic and prolactin-reducing agent for treating disorders caused by reduced cerebral and peripheral circulation
Inventor: WETH GOSBERT DR MED DR RER NAT
IPC: A61K31/195
Filed: 1990-05-25
Abstract: The use of N-(aminoacyl) amino acids (I) and their salts in dopaminergic and prolactin-reducing medicaments (II) is claimed. (I) is preferably (2R,4R)-2-(2-hydroxyphenyl)-3 -(3-amino-propionyl)-4-thiazolidine carboxylic acid or 1-((2S)-3-amino-2-methyl- propionyl))-2-proline. USE/ADVANTAGE - To treat diseases involving reduced cerebral and peripheral blood circulation (claimed). (I) are known to reduce blood pressure by inhibiting angiotensin II, and so would be expected to reduce levels of noradrenaline and hence of dopamine, but experiment shows that the opposite occurs. In an example, 24 patients with reduced cerebral and peripheral blood supply were treated with anapril hydrogen maleate (Ia), an N-(aminoacyl) amino acid derivative. After 15 minutes, dopamine levels were significantly raised (105 pg/ml initially, 143 pg/ml after 15 minutes) and continued to rise to a maximum of 253 after 1 hour, before falling to 182 after 2 hours. Prolactin levels were 16.2 ng/ml initially and fell to 10.2 ng/ml after 2 hours. (6pp Dwg.No.0/2)
