Inventor: BEKOOIJ JOHAN PIETER

Abstract: The invention relates to a method for compensating, in a coherent optical communication system with heterodyne detection, at the receiving side phase noise of the transmitting and of the local laser. Characteristic of the present method is that the phase-noise compensation takes place in the LF domain. The two MF heterodyne signals (Imf and Pmf) are first demodulated into LF signals (in which there is still noise), which are subsequently substracted from one another, due to which the respective noise components cancel out each other. Preferably a local laser signal which is, qua frequency, between the two other HF signals is chosen. This offers the advantage that the two MF heterodyne signals can be modulated by one and the same demodulator; because for the compensation of phase noise the demodulated MF signals (Ilf respectively Plf) which are, qua phase noise, in opposite phase with regard to each other are then added to one another. The advantage of the method according to the invention is that the bandwidth for which the receiver has to be suitable is relatively small.

Abstract: A hydraulic continuously variable speed transmission (T) with a direct clutch valve (DC) comprises a hydraulic pump (P), a hydraulic motor (M), a hydraulic closed circuit (La,Lb) for hydraulically connecting the two (P,M), a direct clutch valve (DC) placed in the closed circuit (La,Lb), a speed reduction ratio control actuator (30), and a direct clutch valve controlling device (40) for controlling operations of said direct clutch valve (DC) to block the closed circuit (La) when the speed reduction ratio becomes substantially "1". The direct clutch valve controlling device (40) maintains direct connecting state when an actual engine (E) speed is higher than a direct clutch (DC) disconnecting reference engine speed at the speed reduction ratio of approximately "1". Then, the direct clutch valve control device (40) releases the blocking of the closed circuit (LA) by the direct valve (DC) when a drop of the actual engine speed from the direct clutch (DC) disconnecting reference engine speed exceeds a predetermined amount corresponding to the vehicle speed.

Abstract: An edible plastified dispersion having a continuous fat phase and a dispersed aqueous phase, in particular low-calorie spread, is prepared by a process that includes (i) cooling a constituted emulsion having a continuous aqueous phase and a dispersed fat phase and comprising essentially no solid fat, by passing it through a static heat exchanger to cause partial crystallization of fat, the emulsion leaving the heat exchanger as a dispersion having a continuous aqueous phase and containing crystallized fat, and (ii) feeding the dispersion from step (i) directly to means for imparting kinetic energy so as to invert the dispersion into a dispersion having a continuous fat phase and a dispersed aqueous phase. The use of scraped-surface heat exchangers can be dispensed with, without adverse effects on the product properties. Apparatus for carrying out said process is provided also.

Abstract: The shed formed by the warp threads in a loom is changeable by a shed drive that may either be an eccentric drive or a shaft drive. In order to rapidly exchange one shed drive (2) by another shed drive (3) these shed drives are mounted individually in a respective carriage (4). The carriage is constructed for docking in an exchange position next to the loom. An empty first carriage can take up a shed drive currently cooperating with the loom to remove the shed drive from the loom. A second carriage carrying another shed drive can then dock in the exchange position after the second carriage has been removed. The carriage is positionable either manually or automatically in response to distance signals.

Abstract: This arrangement enables high-resolution screens (HB) with a single pixel selection to be used and avoids the derivation of a check code from the serial picture data stream which is problematic at very high frame buffer read-out frequencies. To form the check code, the picture data, which are entered into the frame refresh buffer (BW1), are entered in parallel to another similar buffer (BW2) which is not followed by a screen and are immediately subsequently read out of the further buffer to a check code generator (P). A check code generated by the check code generator is compared with a previously stored reference code and checked for correspondence in a control processor (SR) requesting the signalling frame display. An error is indicated if there is no correspondence. <IMAGE>
