Abstract: A modular engine enclosure comprised of a hood and baffle is provided to channel cooling air along passages formed between their adjacent surfaces to the radiator of a water cooled engine. The passages provide acoustic air barriers and along with selected enclosure surfaces covered with sound absorbing foam, serve to contain engine sounds within the enclosure. The passages receive air from a generally upright inlet opening and direct it evenly over the top surface of the horizontally oriented radiator.  After being drawn through the radiator, the air is exhausted generally horizontally out the back of the engine compartment. The modular construction of the enclosure allows it to be easily raised and/or removed so that maintenance and service activities can be performed on the engine and its components.

Abstract: A process for recycling colored polyamide material comprises the steps of (a) contacting solid colored polyamide material with an organic solvent composition at a temperature effective to dissolve the polyamide, thereby forming a solution containing colorant and dissolved polyamide; and (b) separating colorant from the polyamide. The process can optionally further comprise the step of recovering the colorant, recovering the polyamide, or recovering both the polymer and colorant. The organic solvent composition preferably is selected from the group consisting of aliphatic and aromatic ketones, aliphatic and aromatic alcohols, diols, water, and combinations thereof. Solvent compositions comprising at least one alcohol selected from the group consisting of butanediol, butanol, ethanol, and benzyl alcohol are preferred, such as aqueous solutions of 1-butanol or ethanol.

Granted: 2003-04-15
Abstract: A device and a process for charging of rechargeable NiCd, Ni-metal hydride or lithium batteries (12) of implants by transcutaneous transmission of electric power from an external power transmission part (11) to a power receiving part (10) which forms a part of the implant. The charging device is provided with a charging current detector (27, 32, 34) which, in a first charging phase (T1), allows a relatively high charging current (I L) to flow and which, after the cell voltage (U2) of the battery has reached a predetermined limiting charging voltage (U G), in a second charging phase (T2), reduces the charging current as compared to the charging current which flows at the end of the first charging phase. The charging current detector is made such that, during the second charging phase, it sets the charging current to a value causing the cell voltage during the second charging phase to be kept at least approximately at a predetermined constant voltage value (U G).

Abstract: A method to prevent graft rejection of transplanted cells, tissues or organs without general immunosuppression is described. The method employs a newly discovered protein, LAG-3. When allogeneic or xenogeneic cells are engineered to express LAG-3 on their surface and transplanted, immune destruction of the implanted cell, tissue o r organ is prevented, while the host's immune system remains functional. A particular application of this method allows the preparation o f a universal gene therapy host cell expressing LAG-3 on its surface for protection from graft rejection by a host's immune system.</SDOA B>

Abstract: A permanent magnet D.C. torque motor has the stator mounted in cantilever from a base and nested in a cup-shaped rotor journalled for rotation on the base.  The permanent magnets are disposed about the inner periphery of the rotor. The stator core has a plurality of radially outwardly directed webs with coils therearound and may be formed integrally as one-piece or laminated. The pole segments may be integrally formed with the web or attached as separate members. The pole segments have truncated cylindrical pole shoe surfaces forming radial air gaps with the rotor magnets.  The pole segments extend axially and transversely beyond the webs. The axial pole segment extensions provide increased total flux for a given motor volume without an increase in ampere turns of electrical energization. The motor of the present invention is particularly suitable as an engine air throttle actuator.

Abstract: A damper valve for a hydraulic power steering device is disposed in a hydraulic oil circuit connecting an oil passage changing-over valve in a gear box and left and right oil chambers of a power cylinder. It is provided with a piston valve which is opened by through-flow of hydraulic oil returned back to the oil passage changing-over valve from either one of the left and right chambers of the power cylinder, and a check valve which is disposed in a valve body of the piston valve and which allows only hydraulic ail supplied from the oil passage changing-over valve to either one of the left and right chambers of the power cylinder to flow through the check valve. The piston valve is structured such that a throttle oil passage is formed by through flow of the returned hydraulic oil having an oil pressure of a predetermined value or less, and a fully opened oil passage is formed by through flow of the returned hydraulic oil having an oil pressure of more than the predetermined value. Oil passages for the returned-back hydraulic oil are formed in the valve body of the piston valve.

Abstract: A respective support is arranged at each side at the underside of an escalator step, wherein a first fastening is provided at the upper support end for a transport chain and a second fastening (6) is provided at the lower support end for a guide roller. The second fastening (6) consists of a cantilever arm (7) and a bearing pin (8) with a bore (9), which are integrated components of the escalator step, wherein escalator step, cantilever arm (7), bearing pin (8) and bore (9) are produced in one casting.

In order to save the working process of thread-cutting, a countersunk self--tapping screw (13) is used for fixing the bearing (11). The countersunk self-tapping screw (13) plastically forms an exact internal thread in the bore (9). On tightening of the screw (13), a washer (14) lying under the screw (13) presses on an inner ring (12) of the bearing (11), whereby the bearing (11) is exactly positioned against a shoulder (10) and held by the washer (14).

Granted: 2006-06-06
Abstract: L'invention concerne un système de reproduction sonore permettant de convertir en signaux destinés à plusieurs canaux de sortie, les signaux stéréo de deux canaux d'entrée (92, 94), le codage et la corrélation de l'une des composantes du signal au moins étant directionnels et le codage de l'une des composantes du signal au moins étant non directionnel et non corrélé. Ledit système comprend un décodeur (90) destiné à renforcer la composante de corrélation des signaux d'entrée dans le sens voulu et à réduire la puissance de tels signaux dans les canaux qui ne sont pas associés au sens de codage. Toutefois, on préserve la séparation entre les canaux de sortie respectivement gauche et droit (172, 176) et l'énergie totale de la composante non corrélée des canaux d'entrée dans chacun des canaux de sortie. Il en résulte que les instruments enregistrés sur le canal d'entrée droit restent du côté droit des canaux de sortie et que les instruments enregistrés sur le canal d'entrée gauche restent du côté gauche, et que la sonie apparente de tous les instruments de tous les canaux de sortie ne change pas quel que soit le sens de la composante des signaux d'entrée à codage directionnel. Le système comprend également des organes de codage destinés à coder cinq canaux d'entrée, si bien que ces derniers feront le codage en respectant les conditions de sens et de niveau dans les décodeurs de l'invention, ainsi que dans les décodeurs conformes aux standards de film courants.

Title: Biocompatible polymer film
Inventor: DEPPISCH REINHOLD
IPC: C08G81/00
Filed: 1999-10-08
Granted: 2009-05-19
Abstract: The present invention includes a co-polymer film which can be applied over a surface of an article to form a continuous surface that is more biocompatible and has a smoother surface morphology than an untreate d article. In general the co-polymer film of the invention can be formed by providing a hydrophobic polymer block, such as polydimethylsiloxane (PDMS) with functional -OH end groups and reacting the -OH ends with a conventional monomer or prepolymer of a film- forming polymer capable of reacting with -OH groups. Such reactions am exemplified, using as reactive PDMS a triblock copolymer of the polylactone-polysiloxane-polylactone (PL-PDMS-PL) type, or silicone polyesters. The -OH groups of the polylactone blocks can react with any of a variety of isocyanates in a suitable solvent to form a polymer having PDMS incorporated with its structure. The film can be applied to the surface of an article by any convenient means of coating the article with the reaction mixture in solvent, and allowing th e solvent to evaporate.
