Patent DE-3277826-D1 (DE)
Title: Solenoid operated clutch engagement
Inventor: MCCARTHY JAMES
IPC: F16D48/02
Filed: 1982-08-04
Granted: 1988-01-21
Abstract: The transmission includes a solenoid, a valve operated by the solenoid, a check valve, a pilot valve, a low pressure regulator valve, a positive displacement pump, a reservoir or sump, and a clutch. The pump is designed to deliver more fluid than is required by the transmission, with the excess recirculated by the pressure regulator system. The low pressure source of hydraulic fluid communicates with the clutch cylinder through check valve and pilot valve until pressure in the cylinder attains a level at which the check valve closes. The piston will have brought the several clutch discs into mutual abutting engagement, or the brake band into engagement with the brake drum. The solenoid valve operates to quickly fill the clutch cylinder at relatively low hydraulic pressure during initial clutch engagement, and to quickly vent high pressure fluid from the cylinder during the early stages of disengagement.

Patent DE-3372022-D1 (DE)
Title: Method and device for controlling a step motor
Inventor: GUERIN YVES
IPC: G04C3/14
Filed: 1983-10-05
Granted: 1987-07-16
Abstract: The rotor of a stepping motor may remain blocked in an intermediate position different from a rest position if its control circuit adjusts the electric energy of the driving pulses to the minimum corresponding to the actual mechanical load of the motor determined by a measuring circuit. To remove this risk, the method consists in producing with the aid of a generator and applying to the motor, pulses which allow release of the rotor when it has remained blocked in an intermediate position in response to a driving pulse. The release pulses are distinct from any correction pulses which are applied in known manner to make up a lost step. The release pulses precede the correction pulses and are preferably of such polarity as to return the rotor to its starting position to ensure correct action of the ensuing correction pulses. This method applies in particular to the control of the stepping motor of an electronic timepiece.

Patent DE-3382774-D1 (DE)
Inventor: LOPEZ DE ROMANA EDUARDO AGUSTI
IPC: G11B7/12
Filed: 1983-08-04
Granted: 1995-02-02
Abstract: The present invention relates to a method and means for monitoring the focussing condition of the writing light beam impinging the writing surface of a recording medium. Systems for monitoring the focus condition of a light beam used in reproducing prerecorded information from a videodisc by a videodisc player operate by splitting off reflected light from the incident light beam path in a region where the incident beam is diverging. In this manner, the reflected beam entering the polarizing cube, placed in the diverging portion of the incident beam, produces a converging light beam diverted to the photodetector. Because of numerous problems in attempting to apply player concepts to writing machine, it has been common practice in the prior art of recording laser discs to periodically determine optimum focussing position for the various optical elements affecting focus by producing a series of test discs and playing back each disc or portion thereof corresponding to a particular combination of settings for the various optical parameters such as power and focus involved. The empirically derived conditions necessary to produce acceptable focussing conditions, however, are extremely costly due to the labor time involved in setting up and determining the optimum focus conditions as well as in the loss of videodisc production due to down time of the mastering machine. The present invention operates on the recognition of the fact that, although for all practical purposes a light beam from a laser device is collimated, it, in fact, is very slightly divergent as it emerges from the laser resulting from diffraction of the Gaussian intensity profile plane wave that exists between the laser resonator mirrors at the beam waist and from refraction as the output light traverses the thickness of the output mirror. Accordingly, since the beam exiting the laser tube is slightly divergent, the reflected light from the videodisc, even though a small in intensity, is conversely (provided the system is in focus) convergent as it passes in reverse direction through the diverging lens and on toward the output of the laser device and beyond to the conjugate point where it forms a real image of the source plane wave, thus eliminating the need for a relay lens. The present invention makes use of this slight divergence and convergence of the incident and reflected beams, respectively, at the exit end of the modulator to effect monitoring of the focus condition of the writing beam.

Title: Arrangement for path selection in a communications network
Inventor: KATZEFF KURT
IPC: H04L69/14
Filed: 1984-10-23
Granted: 1988-03-03
Abstract: The communication network is integrated for data, telephony, text and/or picture handling, and incorporates terminals (T1-T4) and computers (P1-P4). Each terminal can be connected to a required computer which carries out a work process as needed by the terminal. For activation purposes, the terminals can be connected to a path selector (RI,RS,RD,RE) for transmission to it a definition of the type work which it requires. On receipt of this definition, the path selector defines to the terminal the traffic path it should use for contacting the computer capable of executing the desired work. Once this information is received by the terminal, the connection between it and the path selector is terminated. The path selector is controlled by means of a monitoring unit in the network  which governs its directional function.

Title: Method and device for preventing slipping and/or skidding between driveable and breakable wheels and the supporting surface in vehicle traction systems
Inventor: SJUNNESSON LARS
IPC: B60T8/175
Filed: 1984-05-09
Granted: 1988-09-15
Abstract: Comparators (K1,K2) compare rotary speeds of the wheels on a respective axle (W1,W2) derived from a respective pick-up and output signals to logic AND and OR circuits (C,D). Similarly, further comparators (K3-K6) indicate, on the basis of acceleration-representative signals, which wheel or axle is exhibiting excessive acceleration or deceleration relative to the other wheels or axles. A digital signal processor determines whether vehicle acceleration or deceleration is to be expected, on the basis of signals. The signals are output by switching devices (S1,S2), by a transducer sensing the control parameter e.g. hydrostatic power transmission system pressure or traction system current, and by a vehicle travel direction detector. The processor determines whether wheel-slipping or skidding is to be expected and forms an electric expectation output signal.
