Patent EP-0308554-A1 (EP)
Inventor: KELSEY CHRISTOPHER GEORGE
IPC: F16K13/00
Filed: 1987-09-24
Abstract: A fluid control valve has two cylinders arranged parallel to each other with their surfaces in contact. At least one of the cylinders has a groove formed in its surface extending partially around the circumference and varying in depth along its extent to define an aperture for fluid to flow through. This aperture can be varied in size by rotating the cylinders thereby controlling the flow rate of fluid through the valve. The cylinders are rotated in the same direction such that their contact surfaces move in opposite directions. This arrangement provides a wiping action to reduce the likelihood of jamming when the valve is operated. The cylinders are rotated by three interengaging pinion gears driven by suitable drive means.

Abstract: A system for coupling to a swivel plough (3, 4) of an agricultural appliance to be towed (6) which comprises a frame (7) to which is attached a coupling bar (10), itself attached to the appliance to be towed (6). In order, in particular, to allow the centering of the latter on the ploughed soil and the reversals of the plough, the attachment point of the frame (7) is located on the soil-turning side and substantially in a mid-plane in relation to the two series of ploughing bodies, and the attachment devices (9, 11) make it possible for the appliance to be towed to have a direction of movement (13) different from that of the tractor and movements of the frame attachment point in which it can be both raised and lowered and be overturned. The invention is used particularly for an appliance for the additional preparation of the ground after ploughing. <IMAGE>

Abstract: Selon un procédé de compensation de la tension offset d'un amplificateur de réglage (RV), la sortie de l'amplificateur de réglage (RV) est séparée de l'organe final (SG) du circuit de réglage. La valeur de la tension mesurée de compensation de l'offset est mémorisée. Une fois que la tension de compensation de l'offset a été mesurée et enregistrée, la sortie de l'amplificateur de réglage (RV) est à nouveau connectée à l'organe final (SG) du circuit de réglage. La tension mémorisée de compensation de l'offset est appliquée à l'entrée de l'amplificateur de réglage (RV). Ce procédé est utilisé par exemple dans le circuit de réglage de la focalisation d'un tourne-disques à disques compacts. A chaque fois que le tourne-disques est débranché puis branché à nouveau, la tension de compensation de l'offset est de nouveau mesurée, mémorisée et réappliquée à l'entrée de l'amplificateur de réglage (RV).

Abstract: Dans le procédé de compactage de matériaux pulvérulents, le processus de compactage suivant est déclenché par un choc: un choc D1 agit au moment t1 sur la surface de matériau pulvérulent et simultanément on fait agir un choc D2 au moment t2 sur une région de la masse pulvérulente qui est distante de ladite surface et du modèle de façon que l'air amené dans la masse pulvérulente par le choc D2 ait le temps de s'échapper avant que le choc D1 n'atteigne la plaque-modèle. A cet effet, des ouvertures (9) sont prévues dans la plaque-modèle (2). Ces ouvertures sont disposées le long de toute la paroi (3) du moule et leurs grandeurs et nombre varient en fonction de la distance entre la paroi (3) et le modèle (2) ou en fonction de la forme du modèle. L'avantage de ce procédé est que des espaces réduits entre la paroi du moule et le modèle peuvent être compactés de façon efficace, ce qui a pour résultat un meilleur remplissage du moule. Ainsi, les avantages économiques du procédé sont évidents.

Abstract: The invention provides a cutoff control system having a capture range equal to the length of the image (signature) which is highly tolerant of spurious transitions, such as lateral shifting and instantaneous interruptions of the web. A highly pipelined hardware correlation unit, cooperating with several high speed RAM devices having independent address generators, is used to cross-correlate new patterns with a reference pattern. An illustrated system for relating a cyclical machine operation to the position of images on a web includes position adjustment means (24,30,84) responsive to control signals for varying the effective position of the machine operation along the moving web, means (34,40,50) for generating image signatures indicative of the image at respective sampling intervals during the matching operation cycle for respective machine cycles, means (56,58,68,72) for selectively generating reference pattern indicia from a first image signature and for selectively generating comparative indicia from a successive image signature, means (71) for generating correlation cooeficients in accordance with the differences between the reference pattern and shifted versions of the comparative indicia, means (68,69,70) for processing the correlation coefficients to determine which of the comparative indicia produced the largest correlation coeficient and generating an indicating signal in response thereto, and means (80) for generating the control signals to the position adjustment means in accordance with the indicating signal.

Abstract: The use is avoided of loading pumps for feeding bit lines when programming memory cells (2) connected to a bit line (11) by carrying out (19) a pre-loading of this bit line simultaneously with the neutralisation (17) of the selection of this bit line. Subsequently, the pre-loading potential is decoupled (19) and the effects of neutralisation are stopped (17). It is shown that by doing this the collapse is avoided of a single programming potential generator (VPP) employed to feed all the bit lines. This results in a space saving on installing circuits for controlling the memory cells of the memory plane. This method can be implemented in particular in page-mode programming of memories whose memory cells comprise floating-gate transistors of the EEPROM type.
