Patent EP-0305152-A1 (EP)
Inventor: SHEENAN PATRICK GERRARD
IPC: B65G53/26
Filed: 1988-08-24
Abstract: In a system for discharging particulate material 2 from a reactor 4, the material is conveyed pneumatically from a drain zone of the reactor via a first vacuum line to a gas/solids separator 12 and solids we fed from the separator to a receiving vessel 16 via a gas-tight line 15 and an inlet port provided on a cover member sealingly engaged with the top of the vessel. The majority of the gas is re-cycled from the separator 12 to the drain zone via a main vacuum return line and the remainder of gas is drawn from the separator to the receiving vessel via a further vacuum line and a gas inlet provided on the cover member. Gas is passed from the receiving vessel to the main vacuum return line via an outlet port provided on the cover member and an auxiliary vacuum return line. The cover member is mounted for movement towards and away from the receiving vessel so that successive receiving vessels can be covered by the cover member and filled with separated solids.

Abstract: A process is described for forming a composite cast article comprising an aluminum-silicon alloy matrix containing a modifying amount of strontium and a preform of bonded-together reinforcing fibres incorporated in the matrix, in which the preform of reinforcing fibres is infiltrated under pressure by a melt of the alloy and the composite article thus formed is allowed to solidify by cooling. According to the novel feature, the fibres of the preform are coated with strontium, preferably in the form of Sr0, before being infiltrated by the alloy melt. The strontium on the fibres is free to react with the Al-Si melt and thus modify the structure in the region of the preform such that an excess of silicon particles adjacent the fibres is avoided.

Abstract: The invention relates to secateurs/pruning scissors which are provided with a cutting jaw at a distance above a geared-down mechanism and which can be positioned with great ease at a variable distance, even through thick stems. It consists of a general support (1) which has at one end a hook-blade and at the other end an element for attaching a handle. An articulated blade (2) which is secured on the base receives directly the movement by a connecting rod (3) which is connected to an inter-support lever (4) centered on the general support and controlled manually by means of a string. A spring (5) actuates the lever (4) in such a way as to command the opening of the tool. The lever, the connecting rod and the spring are retracted along the general support and beneath the articulated blade. The invention may be used for pruning back trees, fruit trees, decorative plants, and, generally, pruning trees with dense foliage. <IMAGE>

Abstract: The expanding cone (1d) of an expanding dowel, consisting of an anchor bolt (1) and an expanding sleeve (2), has a cone angle (alpha) which is larger than the cone angle (beta) of the hole (2d) (which enlarges towards the front end (2a)) of the expanding sleeve (2). The expanding sleeve (2) is provided with a circumferential annular bead (2e) in the expanding region. The wall thickness of the expanding sleeve (2) reduces in the expanding region in the circumferential direction to the longitudinal slots (2c). As a result of these measures, it is achieved that the expanding sleeve (2) is expanded very sharply at the start of the expansion process and the annular bead (2e) is pressed into the wall of the hole. The positively locking connection, produced in this way, of the expanding sleeve (2) to the supporting material permits the use of the expanding dowel even in tension zones of a building where there is a risk of cracking.

Abstract: A speed controller wherein feedback data necessary for controlling the speed of a servo-motor are received from a pulse coder in a discrete data form and are digitally processed by a microprocessor to form a predetermined control command. In sampling the data at a predetermined sampling period so as to cope with the processing by the microprocessor, the lag element at a moment when the data is received by the processor as a speed data makes the control of servo motor inacurrate. Therefore, a detecting signal forming unit (5) processes the discrete count data as the sum of the count data that are divided by an integer of a sampling period in synchronism with the sampling period, and sends to a speed processing block (3b) the speed data as the latest speed data necessary for processing at a predetermined sampling period, whereby the effect of the lag element is minimized, thus enabling the microprocessor to fully exhibit its ability to accurately control the speed.

Abstract: Procédé de fabrication de dispositifs de circuit CMOS sur un substrat (26) isolant, dans lequel un procédé d'épitaxie en phase solide est appliqué à des îlots (28, 30), pour les dispositifs indivuduels dans la même étape que les implants (8, 10) dopants de canaux. Une espèce d'ions (12), de préférence du silicium pour un îlot de silicium, est implantée dans chaque îlot (28, 30) à une énergie et un dosage suffisants pour rendre amorphe une couche noyée de l'îlot à proximité d'un substrat (26) isolé sous-jacent; on emploie de préférence du silicium-sur-saphir (SOS). Les couches noyées sont ensuite recristallisées, en utilisant des parties non amorphes de l'îlot semi-conducteur comme graines de cristallisation. Des îlots de matériau semi-conducteur de haute qualité généralement uniforme sont ainsi obtenus, lesquels utilisent plus efficacement des implants dopants, et évitent les transistors parasites de l'art antérieur et les courants de fuites. En implantant l'espèce d'ions à une profondeur plus grande que l'épaisseur d'îlot nominal pour des dispositifs de canaux n, et à une profondeur inférieure à l'épaisseur d'îlot nominal pour des dispositifs de canaux p, la fuite de courant du canal arrière est réduite alors que l'auto-dopage indésirable de l'aluminium est évité pour les dispositifs de canaux p.

Abstract: Un conduit (11) à parois minces est fixé, dans l'enveloppe (13) refroidie au liquide, par des vis (16) réparties autour de la circonférence du conduit (11), dans le plan d'une section transversale. Des taquets (17) de réception des vis (16) agencés dans la paroi du conduit (11) présentent un filetage interne correspondant aux vis (16). Dans la position de montage, un écart radial en moins est présent au niveau de chaque taquet (17) entre le conduit (11) et l'enveloppe (13), cet écart étant supprimé lorsque les vis (16) sont serrées. A cet effet, le conduit (11) est déformé dans le plan de la section transversale où se situent les vis (16), dans les sections entre les taquets (17). L'importance de la déformation dépend de la dilatation thermique attendue du conduit (11) lors de son utilisation. On élimine ainsi dans le conduit (11) chauffé pendant son utilisation les forces de liaison résultant d'une dilatation thermique entravée.

Abstract: The invention is related to a submarine vehicle for the deep ocean research. This vehicle is composed of a penetrator (1) and of a support structure (2 to 7). The vehicle descends by gravity due to a ballast disposed in the lower part (11) of the penetrator. Apart from this ballast, the vehicle can be recovered due to a discoupling of the ballast by an explosive bolt (13). After discoupling, the float clusters (8) located in the upper part of said support structure supply the mount­ing thrust necessary for transferring the vehicle up to the ocean surface. If this thrust is insufficient, a pyrotechnical device (15) can be provided, which inflates a bag and thus creates an additional thrust directed to the upside. 
     The invention is particularly useful in the investigation at the deep ocean sea-bottom.

Abstract: A method of, and apparatus for, leak testing a package, in which the package (6) is placed in a sheet-like, gas-tight envelope. A pressure differential is generated between the outside and the inside, as a result of which the package is closely enveloped by the envelope. This pressure differential is so large that it decreases the volume of the package and increases the internal pressure in the non-filled portion thereof. In the space (16) ("measuring space") between the package and the envelope pressed against it, a pressure is used which is lower than the increased pressure in the package. In the sealed measuring space, the change in pressure is measured for a pre-determined measuring period.
