The invention relates to low density cellular, rigid polyurethanes which employ the dimethyl esters of adipic, glutaric and succinic acids and mixtures thereof in conjunction with nonylphenol as cell-opening agents. The use of this ester phenol mixture obviates the need of other surfactants, particularly silicone surfactants which reduce the adhesion of the urethanes to fabrics in pour-behind-fabr...

O.Z. 0050/43120 Thin regenerated polyglucan films useful as, for example, membranes are prepared by reaction of polyglucan with a silylating agent, film formation by the Langmuir-Blodgett technique or by spin coating, and desilylation by means of a gaseous mineral or organic acid.

Disclosed is a method of removing synthetic and natural resins from an artic le containing an epoxy resin without damag- ing the epoxy resin. The article is contacted with a solvent having formula (I) where n is 1 or 2, which dissolves the synthetic and natural resins and forms a solution. The solution is then separated from the article. The solvent can be recovered from the solu- tion.; 2130354 9...

An improved method of controlling catalyst inventory in the reactor of an ebullated bed process has been discovered. Pressure differentials are measured to calculate a catalyst inventory characterization factor. This factor is calculated by means of a new algorithm. Aged catalyst is withdrawn and fresh catalyst added in an amount to reestablish the value of the factor. The catalyst to oil ratio i...

JJM-28 14 BIOABSORBABLE WOUND IMPLANT MATERIALS Heteromorphic sponges are described which have matrix structures with oriented substructures added to facilitate cellular invasion. A sponge may be used as a wound implant by cutting it to the shape of a wound bed and placing therein. The matrix structure provides conduits which assist invasion of the sponge by cells which degrade the sponge and lay ...

A covered pressure-sensitive, self-adhesive carrier in which the carrier is covered by an embossed material, such as a film, on the surface of the carrier which is pressure-sensitive and self-adhesive resulting in a covered carrier wherein the adhesion between the cover and the adhesive can be modified depending on desired need. The cover layer can be removed and recycled.

A vascular stent (8) for reducing hemodynamic disturbances caused by angioplasty. In one aspect, the stent is formed from a single, continuous filament (11) having a series of U-shaped bends (1-7'). The filament (11) is wrapped around a mandril (31), in a circular fashion, to align the curved portions of each bend (1-7') which are then connected. In another aspect of the vascular stent, the filame...

PATENTS 60SI-1517 : A diorganopolysiloxane polymer, an M-stopped fluid, a silica filler, a calcium carbonate filler, and gammaaminopropyl triethoxysilane cures at room temperature in the presence of a tin catalyst and a cross-linking agent to form an RTV elastomer having good adhesion and retainable tensile strength in the presence of hot engine oil.

PROCEDE DE NETTOYAGE D'UNE INSTALLATION DE SEPARATION DES COMPOSES DE SILICIUM CONTENUS DANS UN BAIN DE DECAPAGE CHLORHYDRIQUE DE PRODUITS EN ACIER ET DISPOSITIF POUR SA MISE EN OEUVRE L'invention concerne un procédé de nettoyage d'une installation de séparation des composés de silicium contenus dans un bain de décapage chlorhydrique de produits en acier, dans laquelle le bain usé est recyclé aprè...

A physical form of n-[4-[5-(cyclopentyloxycarbonyl)-amino-1-methyl-indol-3-ylmethyl]-3-methoxybenzoyl]-2-methylbenzene-sulphonamide substantially free of other physical forms, which form is crystalline, has an x-ray powder diffraction pattern with specifi

A communications network includes satellites, which serve as switching nodes and move in orbits about the earth. The network additionally includes stationary switching offices. Mobile communication units communicate with the network through the satellites using TDMA data packets and network control messages. The switching offices couple to PSTNs. Each mobile unit is managed by a nearby switching ...

A wireless, dynamically reconfigurable link layered communications network and method are disclosed. A destination transceiver such as, a central transceiver, has a unique, permanent identification with a predetermined numerical link layer level n. A plurality of remote transceivers each having a unique, permanent identification and a variable, stored numerical link layer x where x > n and x and n...

A welding management apparatus for use with a tube production machine. A workpiece (1) fed from a roll of metal strip is formed in a tubular formation having side surfaces (1b,1c) opposite to each other. An upsetting pressure is applied to joint the opposite side surfaces of the workpiece at a jointing point. A high frequency power is supplied to the workpiece (1) to weld the opposite side surface...

The device allows detecting of the formation of ice on the external structures of aircraft and naval or land equipment on which it is installed. The sensor is composed of a certain number of metal plates, separated from plates of dielectric substance, which have the same shape as the metal plates, but slightly smaller external dimensions, figure 1. The alternate metal plates are electrically joine...

The machine comprises a heater in a side arm and a steam engine above the latter. This is located between the gas burner and the bowl. The steam produced by the heater moving towards the arm drives the motor at the end of the connecting rod on which a spoon is positioned in various locations along the radius. The work of the machine does not cost anything because it makes use of the same energy wh...
