Patent EP-0312279-A1 (EP)
Inventor: STROUCKEN KLAUS
IPC: B04B11/06
Filed: 1988-10-11
Abstract: The invention is related to a liquid separator having a centrifuge rotor (1) with a set of conical separation discs (21) arranged coaxially in the separation chamber (13). The inlet of the separation chamber is formed as inlet passages (20) which extend radially outwards from a central inlet chamber (16) in the rotor along the end wall of the separation chamber towards which the separation discs turn their apex ends. The inlet passages (20) are formed between said end wall and partition member (18, 19) situated between the rotor end wall and the separation discs (21). 
     The outlet of the separation chamber (13) for separated liquid is formed by a number of channels (22) through said partition member (18,19) and aligned channels through tubular members (23) bridging said inlet passages (20). The channels through the tubular members (23) thus cross the inlet passages (20) and communicate with the channels (24) in the above said rotor end wall, which channels (24) also constitute parts of the outlet from the separation chamber (13) for separated liquid.

Abstract: The method involves projecting a beam of coherent light on to an element of the textile surface (7) to be checked and optically processing the transmitted or reflected light so as to obtain the diffraction spectrum of the said element (7). This spectrum is superimposed on the recorded hologram (6) of an element (called the reference element and belonging to the same textile surface) in the front focal plane of a Fourier lens (9). As a result of this, the cross-correlation function of the surface to be checked (7) and of the reference recorded on the hologram (6) is produced, and use is made of the data from the cross-correlation function. The data are used in particular for comparing the intensity of the central peak of the auto-correlation function with the data from the cross-correlation function in the frequency zone corresponding to the said peak. <IMAGE>

Abstract: The electromagnet coil (L) associated with each print needle or hammer is wound on a core to which an armature is held when the coil is de-energised. The current is limited in intensity by a diode (D4) and resistance (R1) in a transistor circuit (V1) for the duration of the initial pulse. This is succeeded by an interval in which an energy recovery capacitor (C) is charged from the coil (L), via another diode (D2), to a voltage limited by a Zener (D1). Finally the capacitor (C) is discharged through another transistor (V2) and an adjustable resistance (R3) into the coil (L).

Abstract: A device is disclosed for scanning a record carrier (1) provided with substantially parallel tracks, which device comprises a closed-loop position control system with position and velocity feedback for controlling the scanning point (P) towards the centre of a specific track. For this purpose the position control system comprises a positioning system (15) for moving the scanning point in a direction transverse to the tracks, a measuring system (4, 6, 9, 10, 11, 12, 13) for generating a velocity signal (RS) which is indicative of the velocity with which the scanning point (P) is moved across the tracks, and for generating a first error signal (RE) whose magnitude, within a predetermined limited range to either side of said specific track, is proportional to the deviation between track centre and the scanning point (P). The position control system further comprises a control circuit (3) for controlling the positioning system depending on the first error signal (RE) and the velocity signal (RS). 
     The control circuit (3) comprises means for generating at least one substitute error signal (PE′, UC′) which within a second range, outside the first range, has a sign which is indicative of the direction of the deviation, the control circuit (3) being adapted to control the positioning system (15) in response to the first error signal (RE) or a substitute error signal (UC′, PE′) depending on whether the deviation is situated in the first range or the second range respectively, in such a way that the error signal employed for position feedback depends on the magnitude of the deviation, and the velocity signal (RS) used for velocity feedback is independent of the magnitude of the deviation.

Abstract: Wheel cradles (140) for a wheel lift towing system are quickly and easily coupled to or uncoupled from opposing ends of a cross arm assembly (120) associated with a towing vehicle (100). The cradles (140) are coupled to the cross arm (120) by sliding the cradles (140) laterally in a substantially horizontal plane from outside the ends of the cross arm (120). Such lateral insertion facilitates coupling of the wheel cradles (140) to the cross arm (120) in situations of difficult access to the towed vehicle's wheels, for example, when the towed vehicle is positioned with two of its wheels abutting a curb. An arrangement for coupling a back-up safety line, such as a safety chain (910), between the towing and towed vehicles provides additional protection against accidental dislodgement of the towed vehicle from the towing vehicle.

Abstract: A transfer differential gear lock controller in accordance with the present invention interlocks a switching operation of a transmission device between a low speed range (LSP) and to a high speed range (HSP) with a differential gear lock operation, controls a center differential gear lock mechanism (4) to a lock state by detecting the operation state of the transmission device in the low speed range (LSP) and makes it possible for a driver to complete his operation with only one shift operation to the low speed range (LSP). The controller makes it also possible to select between the lock state (DLP) and free state (FP) for the center differential gear lock mechanism (4) in response to the detection of the operation state of the transmission device in the high speed range (HSP) through the driver's operation. For, those vehicles which are directed primarily to off-road driving are generally of low and high two-speed type, but in the case of four-wheel drive vehicles equipped with the center differential gear, the center differential gear lock mechanism (4) must be locked under the road surface condition where driving must be made in the low speed range (LSP).

The increase in the spring force which takes place when the compression springs (10) are loaded, is compensated for in the direction of the main oscillation axis (A) by the angle (B) increasing and thus by the force component which acts in the direction (A) becoming smaller, which leads to the force which acts in the direction of the main oscillation axis (A) remaining constant.
