Patent DE-3707383-A1 (DE)
Title: Self-starting synchronous motor having a reversal prevention device
Inventor: MERSCHROTH BERNHARD DIPL ING
IPC: H02K7/118
Filed: 1987-03-07
Abstract: In the case of a self-starting synchronous motor having a reversal prevention device, it is proposed to support the magnet rotor (2), such that it can itself rotate, on the rotor shaft (1) (which is supported such that it can rotate in a housing) and to connect the reversal prevention device permanently to the rotor shaft, likewise coaxially, within the motor housing, coaxially with respect to both, and to arrange on this rotor shaft a locking element which can pivot radially inwards and outwards. The radial movement of the locking element is produced by axial driver projections on the rotor which, in the one contact direction, press the locking element into a wedge-shaped recess which is fixed to the housing, thus blocking the rotational movement of the synchronous motor, while in the other, relevant contact position, which is suitable for rotational movement of the at least one driver projection of the rotor, the locking element is pressed inwards out of the cutout which is fixed to the housing and in consequence drives the rotor shaft, which is permanently connected thereto, during further running. <IMAGE>

Patent DE-3711913-A1 (DE)
Inventor: RUNGE WOLFGANG DR ING
IPC: F16H59/50
Filed: 1987-04-08
Abstract: The gear-shift of an automatic transmission is influenced as a function of a slip signal in such a way that spinning of the drive wheels is prevented. A higher gear is stepwise or steplessly engaged when a slip signal appears to thereby reduce the torque. Torque is increased again later by a lower gear being engaged stepwise or steplessly. The slip signal may also initiate other action before the higher gear is engaged, e.g. it may displace the ignition angle or activate an accelerator pedal control to reduce engine power or it may actuate the braking system. <IMAGE>

Title: Device for filling limitation
IPC: B67D7/36
Filed: 1987-11-21
Abstract: A device for limiting the filling of tank vehicles contains a filling valve which is designed, in particular, as a bottom valve. The device is intended to prevent overfilling of or even damage to the tank with a high functional reliability and without auxiliary energy. It is proposed that a valve 22 is installed in a line 24 connected to the filling valve, the flap 26 of which valve 22 is operatively connected to a float which, during filling, firstly initiates a movement of the flap in the direction of the closed position. When it has reached a given position 34, the flap 26 is moved into the closed position by the flow pressure conditions prevailing in the line 24, the float 10 being raised above the liquid. <IMAGE>
Patent DE-3800246-A1 (DE)
Inventor: STEGER CHARLES BRASHEARS
IPC: B60G17/015
Filed: 1988-01-07
Abstract: An hydraulic actuator (10) for use in an active suspension for vehicles comprises concentric tubes (12, 14) between which sealingly slides an annular working piston (26). The tubular piston rod (22, 24) of the piston (26) extends through an end cap (28, 102) and is provided with passages for the selective pressurisation of contract and extend working chambers (44, 80) extending outside and inside of the piston rod, respectively. A trapped air volume (46) separate from the oil chambers (44, 80) forms an air spring below the moving piston (26). By controlling the air supply a spring of approximately the correct load and rate for the vehicle can be obtained. This removes the static load from the hydraulic cylinder thereby reducing power consumption, and providing a "limp-home"capability in the event that the hydraulic system becomes damaged. <IMAGE>

Title: Gas-liquid heat engine
Inventor: FETTE PETER DIPL ING
IPC: H02K35/00
Filed: 1988-05-05
Abstract: In the known Stirling engines, three essential problem regions exist which are better solved by means of the new engine:   a) An adjustable compression ratio in order to be able to adapt the engine to the power of the respective heat source. b) The energy transfer from the heat source through a wall of the cylinder to the working gas. There is a geometrical limitation of the heat-exchanger surface here, which results in a higher terminal temperature difference in the heat transfer.   c) The use of low-grade heat. The new machine makes possible hermetic sealing of the working gas, better energy transfer to the working gas, and an adjustable compression ratio so that the use of low-grade heat is also possible together with minimal frictional losses in the liquid flow. Two cylinders standing vertically, which are connected at the bottom by means of a tube filled with liquid function in a push-pull manner. Claims 1, 2 and 3. The working gas in the cylinder heads expands and contracts against the surface of the liquid. In this arrangement, the liquid acts both to seal the gas and also as a force-transfer medium. The energy transfer takes place by continuous sprinkling of the gas with hot or cold working liquid which is previously guided over a heater or over a cooler. The conversion of the vibrational energy of the liquid into electrical energy takes place:     a) by means of a ...   Original abstract incomplete.

Title: Device for changing over a portable electric drilling machine from drilling operation to percussion drilling operation
Inventor: NICKE WOLFGANG DIPL ING
IPC: B25D16/00
Filed: 1988-10-08
Abstract: Device for changing over a portable electric drilling machine from drilling operation to percussion drilling operation and vice versa. In a known change-over device of this type, the rounded, motor-side end of the drilling spindle bears during drilling operation against an actuator designed as a slide. The friction ratios quickly become so unfavourable here that adjacent plastic parts can melt away. This disadvantage is removed with the novel device. The spherical end face of the drilling spindle (10) is realised by a ball (15) which is supported on the base (12) of a recess (11) made centrally in the drilling-spindle end on the motor side and is protected against falling out by means of an elastic component (14, 25) which can be combined with the drilling spindle (10). <IMAGE>

Title: Method for transmitting optical signals according to the heterodyne principle
Inventor: PORT MICHAEL DIPL PHYS
IPC: H04B10/25
Filed: 1989-01-04
Abstract: A method is indicated for the bidirectional transmission of optical signals via an optical waveguide (1) according to the heterodyne principle. The two laser waves, a local wave and a signal wave, required for heterodyning are in each case generated by a common laser (2, 5). On both ends of the optical waveguide (1), a laser (2, 5), a modulator (4, 7) and a photodiode (3, 6) are in each case connected via optical couplers (8, 10, 12, 15) on separate paths to said optical waveguide. Two lasers (2, 5) are used which operate at different frequencies, the relative spacing between them being at least 100 GHz. Each of the two modulators (4, 7) in each case modulates the signal wave of the laser (2, 5) located at the opposite end of the optical waveguide (1). The local waves of the lasers (2, 5) are fed directly to photodiodes (3, 6) via couplers (10, 15). The intermediate frequencies are retained as electric signals. <IMAGE>

Title: Producing printing matrix with corrected raster dot sizes - correcting separate partial surfaces w.r.t. standard dependent on their tone value
IPC: G03F3/00
Filed: 1989-08-02
Abstract: Printed dots of the desired tone value and non-printed points are produced within the ink-conveying subject. The variables of the printed dots for the separate partial surfaces assigned to the print matrix carrier are corrected w.r.t. a standard dependent on their tone values. A correction value for deviation of the dot size from the normal standard is formed from the expected tone value sizes in at least one area of the assigned partial surface. The correction value will generally lead to smaller size of raster dot. This can be realised by control of exposure time during copying of exposed printing matrix carriers. The original copies can be presented as useful sized films (7) for scanning (8). Information from the scanner is integrated by a computer (10) for calculation of the correction values delivered to the copier machine (2,2'). USE/ADVANTAGE - Highest possible fidelity to original tone values over while of printed image achieved at the print matrix forming stage.
