Patent EP-0056525-A1 (EP)
Inventor: TAGUE STEVEN A
IPC: G06F7/496
Filed: 1981-12-22
Abstract: A commercial instruction processor executes a decimal divide instruction by counting the number of subtractions by the divisor resulting in a positive remainder to develop the quotient. If a subtraction results in a negative partial remainder, a restoring addition follows the restore the partial remainder to a positive value. The most significant decimal digit of the divisor is compared with the most significant decimal digit of the remainder after each subtraction pass to predict if the next subtraction pass would result in a negative remainder. If so, a quotient decimal digit is stored in a memory, the divisor is shifted one decimal digit position to the right, and a series of subtraction passes are made to develop the next quotient decimal digit.

Abstract: The invention provides an aerator device for dispensing liquid in a gas phase by producing an upwardly-directed spray of the liquid from a tank. The device, which is intended to be submerged in a tank, comprises a motor-pump unit in the vicinity of the tank floor and a primary flared tube and a secondary flared tube coaxial therewith. The secondary flared tube is connected to a delivery nozzle by an intermediate duct, and the delivery nozzle is surmounted by an adjustable needle. The buoyancy of the whole assembly is ensured by a set of variably ballasted buoys which pivot at the end of support arms, and by an upper buoy concentric with the nozzle.

Abstract: Dispositifs d'orifices d'event pour des enceintes de haut-parleurs bass-reflex et plus particulierement dispositifs permettant d'etendre la reproduction de sons jusqu'a des frequences plus basses tout en assurant l'attenuation et l'amortissement, et permettant la reduction des dimensions requises de l'enceinte pour obtenir une reproduction sonore de haute qualite. De nombreux efforts ont ete realises dans le but d'obtenir une enceinte de haut-parleur reproduisant efficacement des sons au niveau de la partie extreme de basse frequence du spectre sonore sans l'introduction de 'booms' et autres effets resonnants. Les dispositifs d'orifices d'event obtenus (22, 27, 30, 34, 38) sont montes dans des enceintes de haut-parleurs bass-reflex (10) derriere des ouvertures d'event (21, 21a-21d). Chaque dispositif possede une ouverture d'une embouchure exterieure au niveau de l'ouverture d'event du haut-parleur et une ouverture de gorge interieure (25, 39, 32, 37, 41) de surface plus petite, approximativement egale aux deux cinquiemes de la surface de l'ouverture de l'embouchure. Les formes des dispositifs comprennent des formes ayant des sections tubulaires cylindriques ou polygonales combinees a des sections de parois extremes planes interieures, une forme en escalier avec une section supplementaire tubulaire interieure, plus petite, et des formes avec des parois hemispheriques et coniques tronquees. Les rapports de surface gorge-embouchure et les rapports des volumes des dispositifs et des enceintes sont tels qu'ils permettent d'etendre et d'augmenter la reponse basse frequence sans produire d'effets de 'booms'.

Abstract: Cet instrument peut fonctionner indépendamment comme support d'aiguille chirurgical pour des opérations de suture et comme dispositif coupant chirurgical pour couper le fil de suture. L'instrument de la présente invention peut être utilisé comme support d'aiguille conventionnel et, dans ce but, il possède une paire de mâchoires (10a, 12a) entre lesquelles une aiguille de suture (A) peut être retenue fermement pour l'opération de suture, et possède également un mécanisme conventionnel de serrage (10b, 12b) permettant de verrouiller les mâchoires en position fermée. Conformément au concept de l'invention, toutefois, un des bras de l'instrument est divisé en deux sections allongées parallèles (12, 16), les deux étant articulées au point de pivot (14) de l'instrument. L'extrémité distale de la première section a la forme d'une des mâchoires de l'instrument (10a), et ce bras fonctionne avec l'autre bras de l'instrument (12a) pour exécuter la fonction conventionnelle de support d'aiguille. La deuxième section du bras fendu possède une lame de ciseau formant une seule pièce avec son extrémité distale (16a) et cette lame de ciseau agit de concert avec une lame formée sur la mâchoire adjacente (12a) pour exécuter la fonction de coupe. La première section est couplée à l'autre bras de l'instrument par le mécanisme de serrage (12b), de manière à pouvoir serrer l'aiguille de suture entre les mâchoires de l'instrument pendant que les lames de ciseau sont actionnées indépendamment pour couper le fil de suture.

A feed part 11 and a doctor part 12 are fastened under this carrier 10 releasably, preferably so that they can be pushed in and out and therefore exchanged. The feed part 11 and doctor part 12 constitute a unit and can be laid elastically against the application surface. The feed part 11 and doctor part 12 can be of varying design. The feed part 11 is preferably made tubular and is supplied with the application medium via feed tubes. It is closed at the end. The feed part 11 can be connected to a rolling doctor, spreading doctor or slotting doctor. Above or next to the preferably tubular feed part is an elastic element 15, for example a pressure pad and diaphragm, a spring arrangement or the like. This elastic element 15 allows the movement of the unit consisting of the feed part 11 and doctor part 12.

Abstract: Apparatus for measuring the time delay between pulse signals, particularly in conjunction with electro-optical range finders. A coarse measurement counter counts the output of a reference oscillator, while a fine measurement interpolator determines the residual time at the start and finish of a measuring interval. Both residual times are successively determined by the same fine measurement interpolator. A delay circuit only supplies the pulse transmitter with the trigger signal when the interpolation for the start signal in the interpolator is ended. An adjustable series of test pulses is produces by a clock generator, in order to form the average value from such a series of measurements in a logic circuit. Preferably, the clock generator is synchronized with the reference oscillator, which ensures the formation of a mean value with a narrow range of errors.

Abstract: The level of released formaldehyde in a durable press treated fabric is significantly reduced or eliminated altogether by an oxidative aftertreatment process in which the fabric (10), after treatment with a formaldehyde-based durable press finishing agent (13) and curing to impart durable press properties, is contacted with an oxidizing agent to destroy formaldehyde-releasing moieties present in the fabric. Preferably, the treatment of the durable press fabric with the oxidizing agent is carried out by impregnating the fabric with a solution (16) containing the oxidizing agent and then providing the fabric (10) a residence time in contact with the oxidizing agent to allow for reaction of the oxidizing agent with the formaldehyde-releasing moieties.

Abstract: A stacked metal-oxide-semiconductor (MOS) device has a lower source (18), drain (20) and channel (34) formed in a silicon substrate (12) and an upper source (30), drain (32) and channel (36) formed in a deposited polysilicon layer (28) which is recrystallized by laser annealing. Instead of the conventional method of depositing aluminum interconnects between the device upper terminals and bonding pads, interconnect parts (29) are formed in the recrystallized polysilicon layer (28) itself. This has the advantages of preventing junction distortion by undesired aluminum penetration into the silicon. Also contact windows do not have to be opened directly to the source and drain terminals thereby easing desing constraints.
