Abstract: Des articles (11) sont formes par compression a chaud de particules metalliques (12) a des temperature se situant entre la temperature de recristallisation et la temperature de solidification du metal ou du solidus de l'alliage apres un premier prechauffage des particules et de la matrice (14). Les particules sont comprimees a chaud pendant une periode de temps tres courte, generalement inferieure a cinq secondes, a 12 tonnes par pouce carre ou plus pour compacter et souder les particules en un article de metal travaille (11) ayant une resistance a la rupture et une resistance isotrope substantiellement plus grandes que celles d'une piece coulee avec le meme metal ou alliage. En outre, les articles (11) peuvent etre fabriques avec une densite theorique de 99% et plus et sans aucune porosite. Les surfaces de l'article peuvent etre lisses et conformes aux tolerances, avec une bonne uniformite de la durete de surface. Les articles peuvent etre formes en utilisant les presses conventionnelles pour fabriquer des articles de maniere repetee sans que ceux-ci ne se soudent aux parois de la matrice meme lorsqu'il s'agit de particules d'aluminium. De preference, les particules sont plus grandes que les materiaux en poudre conventionnels utilises dans la metallurgie des poudres et elles sont ecrouies pendant leur compression a chaud.

Inventor: CLIFFORD ARTHUR GEOFFREY
IPC: B01D17/02
Filed: 1980-01-25
Abstract: A separation apparatus (10) for handling a mixture with a readily flowable liquid component (29) of slightly greater specific gravity, for example separating a heavy viscous grease from water. A preferred form of apparatus comprises an upright cylindrical tank (11) including a central cylindrical core (14) and an outer wall between which a separation channel is defined. The channel has a spiral ramp (12) defining its base and is swept by an upright skimmer paddle (24) driven for rotation about the axis of the tank (11). Two apertures are provided in the ramp (12), the first aperture (30) having a trap-door (32) which is normally biassed open and which is closed by impact from a mass of the viscous or solid components (28) as it is swept up the ramp. The liquid component (29) tends to precede the solid or viscous liquid component and so has reached the trap-door (32) before it closes and discharges through this first aperture. The trap-door is then closed by the solid or viscous material which then proceeds up the ramp and is discharged to the second aperture (13). The skimmer paddle (24) there drops suddenly into the second aperture (13) and is then rapidly forced upwardly by a cam track (36) to flick the solid or viscous component (28) off the paddle (24). The apparatus is intended particularly for use in separating grease having metal contamination from the treatment water used for wet blasting of components.

Inventor: MCCARTY VINCENT DENNIS
IPC: H01F7/18
Filed: 1980-05-09
Abstract: Le circuit de commande de marteau d'impression est commandé par une tension d'alimentation ayant des variations inhérentes de tension. Le courant de commande est appliqué à l'enroulement (30) du marteau d'impression et le niveau de courant dans l'enroulement détecté à l'aide de la résistance (32). Aprés que le niveau du courant dans l'enroulement ait atteint un niveau maximal prédéterminé, un circuit de chronologie (41) est mis en action pour commander la durée d'application du courant maximal. Les variations de la tension d'alimentation sur la durée et la force de frappe sont réduites de façon importante du fait que la chronologie est basée sur le moment où le niveau de courant de commande prédéterminé est réalisé et n'inclut plus le temps de montée. Les variations d'inductance peuvent aussi être compensées par l'ajustement du circuit de chronologie. Peut être utilisé dans tout type d'imprimante à marteau.

Filed: 1980-08-27
Abstract: This clutch consists of a hub (1) to which pairs of friction discs (3a,3b) are attached and of a housing (2) in which the hub (1) is rotatably supported. The spaces between the discs of the pairs of friction discs (3a,3b) form pressure chambers which are connected to the inlet system and the outlet system of the pressure medium. The outlet system has a greater flow resistance than the inlet system. In order to facilitate automatic disengagement of the clutch in the case of an excessive load without any movable final control elements, at least one friction disc (3a) has a through-flow opening (7). This through-flow opening (7) and an outlet opening (6) in the housing (2) are arranged such that they can overlap. The clutch acts as an overload clutch and, in the event of an overload, triggers a pressure pulse in the pressure medium which can be used in control systems. <IMAGE>

Abstract: Une cellule RAM (de memoire a acces selectif) non remanente/remanente (400) utilise un multi-vibrateur bi-stable avec des condensateurs a seuil modifiable, remanents (407, 408) couples a ses bornes de sortie (A, B) pour prevoir un stockage de donnees de reserve dans le cas d'une coupure de courant. Dans un mode de realisation, les condensateurs remanents possedent chacun d'eux une section non modifiable (A) et une section modifiable (B), la section non modifiable ayant soit un seuil d'appauvrissement soit un seuil d'enrichissement. La cellule RAM remanente/non remanente utilise une paire de transistors a effet de champ (409, 410) du type d'appauvrissement ou d'enrichissement pour coupler les condensateurs remanents aux bornes de sortie. Ces transistors de couplage forment avec les condensateurs remanents une paire de noeuds (CD). Les transistors de couplage sont polarises de telle sorte qu'un signal de tension d'ecriture applique aux portes des condensateurs remanents produisent une tension d'amorcage sur l'une des paires de noeuds qui est isolee effectivement des bornes de sortie de la cellule.

Abstract: A method for the realisation of an elevated floor, the upper floor of which is composed of plates of a particular size. In this connection, it was hitherto necessary to cut the plates forming the edge of the upper floor and adjoining the room wall, on site, to a size which corresponds to the intervening space between the already laid plate composite and the room wall. This need is eliminated when, according to the proposal of the invention, a procedure is adopted such that the intervening space is filled, with the use of a permanent shuttering, with a compound which, after application to the shuttering, spreads to form a horizontal surface and subsequently sets in this state.

Abstract: The oxygen demand of waste water (5) having a partial organic composition is reduced by feeding the waste water (5) into an anaerobic digester (2) near the top thereof so as to flow downwardly through the interior of the digester (2). The digester (2) is at least partially filled with a high surface area media (30) carrying on its surface a microorganism which preferentially produces methane when in contact with the organic material in the waste water (5) and also reduces the oxygen demand of materials therein. Nutrients (18. 19) are added as necessary to promote growth of the microorganisms. Methane released from the waste water is collected (at 53) and selectively recirculated to the bottom of the digester (at 60) to break up the biomass thereon. Waste water (5) and biomass is recirculated from the bottom of the digester (2) to the top thereof, preferably at a rate of five times the flow of the influent to the digester (2).
