IPC: A01B63/00
Filed: 1981-07-06
Abstract: A control system for a tractor hydraulical power lift system having an electrohydraulic actuator (22) coupled to a main hydraulic valve (21), wherein the improvement comprises: a feedback electronic control circuit including circuit means for mathematically combining a plurality of transducer generated signals into a command signal. The command signal comprises the output signal of a first differential summing device (32) receiving a first input signal for a control handle transducer (24) from which is substracted a second input signal produced as the output of a signal mixer that combines input signals from a rockshaft transducer (25), a draft selector transducer (26) and a draft load transducer (27). The command signal and a signal from a transducer (28) coupled to the electrohydraulic actuator are fed into a differential summing device (49) that has as its output an error signal representing the actual and desired positions of an implement to be positioned by the power lift system. 
     The control circuit includes a sample-and-hold unit (51) adapted to receive the error signal. A clock logic means transmits the error signal at predetermined times as determined by a sampling frequency clock (52) from the sample-and-hold unit (51) to the electrohydraulic actuator.

Abstract: L'invention concerne un dispositif de refroidissement de secours d'un réacteur nucléaire à eau sous pression, par injection de liquide de refroidissement dans le circuit primaire du réacteur. Il comporte au moins un double circuit d'injection équipé d'un moyen de pompage (36, 37) disposé à l'extérieure de l'enceinte de sécurité (21) du réacteur et un ensemble d'accumulateurs (24, 25) contenant une certaine quantité de liquide de refroidissement sous pression disposés à l'intérieur de l'enceinte (21). Les accumulateurs se répartissent en un premier ensemble (24) à une pression P1 inférieure à la pression du circuit primaire du réacteur et un second ensemble (25) à une pression P2 inférieure à la pression P1. L'injection de liquide de refroidissement par l'un et l'autre ensemble (24, 25) est provoquée par l'ouverture automatique de clapets (27, 31), lorsque la pression du circuit primaire tombe en dessous de P1 et en dessous de P2 respectivement, en cas de fuite sur ce circuit.

Abstract: A seedling growing container is illustrated wherein a number of removable partitions or barriers (B,C) are positioned together in a block. Each of the partitions has interconnected diverging walls forming a series of troughs therebetween open at the top and the bottom so that the partitions (B,C) may be placed in opposing relation as in a tray (A) forming growing compartments from each of the opposing troughs which are in register with each other, suitable for growing a single seedling. Positioning of the plugs is contemplated such that alternate rows of plugs of growing material, each of which is capable of growing a single seedling, are utilized so that each plug will be surrounded for the most part by a partition (B,C) with the remainder being surrounded by an air space for preventing roots from growing from one plug to the other through the process of air pruning. The tray (A) is partially open at the bottom (12), at least to an extent sufficient to provide an opening for heated air to be passed upwardly through the voids formed by the omitted plugs for further encouraging growth of the seedlings. Any suitable means may be utilized for positioning the partition (B,C) together to form a block.

Abstract: Procédé d'élimination d'inclusions gazeuses d'un liquide (10) très visqueux consistant à appliquer au liquide (10) de l'énergie sonore par des klaxons acoustiques (11) ou par d'autres sources acoustiques appropriées, avec une intensité d'énergie suffisante pour induire la migration et la coalescence des inclusions contenues dans le liquide (10), mais inférieure à l'intensité nécessaire pour provoquer une cavitation considérable dans le liquide (10). L'application d'énergie sonore continue jusqu'à ce que la densité de volume des inclusions ait été réduite au niveau souhaité. En général, la fréquence et l'intensité de l'énergie sont sélectionnées et ajustées si nécessaire pour obtenir un mode de fonctionnement tel que le liquide (10) soit soumis à une composante cyclique de tension qui provoque la collision des bulles et leur fusion en plus grandes bulles, et à une composante de tension essentiellement unidirectionnelle, due à des pertes de viscosité et à d'autres phénomènes se produisant dans un champ acoustique (par exemple, pression du rayonnement), qui tend à pousser les bulles en expansion loin de la source (11) de l'énergie sonore, ce qui rend plus aisé leur mouvement vers la surface (13) du liquide (10) et ses environs.
