Patent EP-0147889-A1 (EP)
Inventor: CANDIDO CASILLI JOSEPH
IPC: F01L23/00
Filed: 1984-12-12
Abstract: A diaphragm pump pumping arrangement includes two diaphragm pumps which are arranged and operate in tandem. Each of the diaphragm pumps includes a housing and a movable wall that includes a flexible diaphragm and subdivides the interior of the respective pump housing into a pumping chamber and an actuating chamber. An air distributing control arrangement interposed between and connected to the pump housings includes a spool valve movable in a bore of an aluminum casing of the control arrangement between two end positions in which it alternatingly achieves the admission of the compressed air into one, and discharge of the air from the other, actuating chamber. The spool valve is displaced due to the action of the respective limiting valves accommodated in individual bores of the control arrangement and displaced by the respective movable walls from their rest positions in which they admit the ambient pressure to the associated end faces to their active positions in which they admit the compressed air to the associated end faces of the spool valve. The spool valve carries sealing rings of a material that needs no lubrication, and is made, at least at its peripheral surface, of a material that also needs no lubrication, and the surface bounding the bore for the spool valve is hard-anodized, so that no external lubrication of the control arrangement, by lubricant entrained in the compressed air or otherwise, is needed.

Abstract: Aspring element (12) comprises a strip of fibre-reinforced plastics material formed as a zig-zag consisting of a plurality of limbs lying in substantially the same plane and joined at their ends by reflex portions (14). The strip includes at least a proportion of fibres aligned in its generally longitudinal sense, sufficient to spread stress concentrations away from the reflex portions, in use. The ratio of the limb length to the radius of the reflex portions is desirably in the range 0.2 to 200, preferably 0.5 to 30, and this leads to an extremely compact spring. Several elements (12) can be assembled together, possibly in different planes (eg Fig 6) to produce a spring assembly whose spring rates in different modes of deflection are easily controlled. The spring elements (12) may include elastomer either as blocks (17) in the relex portions (14) or as layers interleaved with fibre reinforced plastics layers (eg Fig 7). The elastomer and plastics materials can be cured in mutual contact, to provide cross-linking between them.

Abstract: On traite ou manufacture à l'intérieur d'une chambre (1) un ou plusieurs objets à une pression inférieure à la pression entourant la chambre. Les types de traitement prévus comprennent un traitement dans lequel un matériau est pulvérisé contre un moule ou un article semi-fini. Un dispositif destiné à l'établissement d'une différence de pression (17), appartenant à la chambre ou compris dans celle-ci, est disposé de manière à évacuer l'air de la chambre après la fermeture de celle-ci. A l'intérieur de la chambre est disposé un dispositif de traitement ou de manufacture, et la chambre présente au moins une porte (8) pouvant être ouverte et fermée. La chambre se compose d'un certain nombre d'éléments auto-portants (2) s'appuyant les uns contre les autres et ayant un faible poids. Les éléments respectifs possèdent une longueur (l) qui représente uniquement une partie limitée de l'étendue correspondante (L) de la chambre. La chambre comprend également des composants de rives ou des composants d'extrémités disposés ou pouvant être disposés de manière à former une jonction avec les deux éléments auto-portants extérieurs (2', 2''). Des organes étanches à la pression sont disposés contre ces éléments et contre les éléments de rives ou d'extrémités (8, 9). Les éléments, les composants et les organes étanches à la pression sont disposés de telle sorte que, malgré la structure légère des éléments, ils peuvent supporter une différence de pression entre l'intérieur et l'extérieur de la chambre, différence produite par le dispositif d'établissement de différence de pression (17).

Abstract: Un appareil de refroidissement d'une électrode à fil métallique pour une machine à décharge électrique de découpage par fil métallique refroidit une électrode à fil (P) en introduisant un fluide de travail à l'intérieur d'un organe de guidage (11) qui guide l'électrode à fil (P). Le fluide de travail est introduit à l'intérieur de l'organe de guidage (11) par l'intermédiaire d'une soupape d'ajustement de débit (17). L'ouverture de la soupape (17) est ajustée en fonction de la pression du fluide de travail qui change selon la vitesse d'usinage. Ainsi, il est possible de maintenir correctement la pression du fluide de travail dans une zone d'usinage et d'effectuer l'usinage tant à de faibles vitesses qu'à des vitesses élevées. De plus, le débit du fluide de travail introduit à l'intérieur de l'organe de guidage (11) est ajusté de manière appropriée, ce qui empêche la déconnexion de l'électrode à fil (P).

Abstract: A valve-seat insert for internal combustion engines comprises a double-layered, sintered alloy composed of a valve-seat layer on which a valve is seated, and a base layer integrated with the valve-seat layer and adapted to be seated in a cylinder head of an engine. The valve-seat layer is composed of a sintered alloy of a high heat resistance and a high wear resistance having a composition comprising, by weight, 4 to 8% Co, 0.6 to 1.6% Cr, 4 to 8% Mo, 1 to 3% Ni, 0.3 to 1.5% C, 0.2 to 0.6% Ca, and the balance of Fe and inevitable impurities, the additives, Co, Cr and Mo being present mainly in a form of a Co-Cr-Mo hard alloy and a hard Fe-Mo alloy dispersed in the Fe matrix. The base layer is composed of a sintered alloy of a higher heat resistance and a higher wear resistance than those of the valve-seat layer and having a composition comprising, by weight, 11 to 15% Cr, 0.4 to 2.0% Mo, 0.05 to 0.3% C, and the balance of Fe and inevitable impurities.

Abstract: The actuator for pivoting one or more supporting arms (11) for transducer heads (19) of record players has an annular flat coil (29) which is arranged with the ring plane transverse to the pivoting axis of the supporting arm (11) in the air gap (35a, 35b) of the circuit of a permanent magnet. The air gap is divided into two, its two parts (35a, 35b) being arranged one behind the other with respect to the magnetic flux (36) of the permanent magnet. Each part (35a, 35b) of the air gap is provided for an electrodynamically active section (29a, 29b) of the flat coil (29), so that a force effect (F) occurs at each of these sections (29a, 29b) when a current is made to flow through the flat coil (29). Since the circuit of the permanent magnet is otherwise closed by way of iron paths (20, 21), extremely weak stray fields are produced and there is optimum distribution of the magnetic resistances in the permanent magnet circuit. The electrodynamically inactive sections (29c, 29d) of the flat coil (29) lie outside the iron area of the permanent magnet circuit, so that they have no neighbouring iron parts which could take up eddy currents. A frame-like structure of the permanent magnet circuit serves for screening against stray fields. <IMAGE>

Abstract: Hoses (52) are tensioned between an input manifold (38) and an output manifold (28), passing round a rotor (34) comprising four sleeved rods (60, 64) which provide the peristaltic pumping action. The input manifold (38) is movably supported by pivotally mounted arms (40) for adjusting the hose tension. The input manifold (38) is pivotally mounted in the arms (40) and the output manifold (28) is pivotally mounted in the front frame so that the manifolds can rock about the axis parallel to the rotor axis and thereby accommodate tilting of the ends of the hoses (52) as the rotor rotates. This reduces hose fatigue. Hose tension is established by a compression spring tightened between a knob (156) screwed onto the end of a fixed rod (142) and a sliding bar (130) acting on the support arms (40) by way of links (116 and 120). A given tightening of the knob (156) towards the bars (130) corresponds to a given hose tension. A stop structure prevents the knob (156) being tightened beyond a setting corresponding to a predetermined maximum hose tension.
