The method for manufacturing YBa2Cu3O7-d system tape comprises; (1) preparing the mixed powders of Y2O3 and BaCO3 in planetary mill and drying them; (2) calcinating the dried powders at 900 deg.C for 10 hours in an air and crushing them to 3-0.5 μm particle size, (3) coating the calcinated powders on the Cu-plated Ag substrate to about 30 μm thickness by diping process, and (4) sinte...

This invention is directed to a method for cleaning a humor replacing circuit, in its entirety, by simply switching valves of joints connected to end portions of ducts which interconnect medical instruments (such as, a membrane type plasma separator, a selective plasma component absorber or a membrane filter); a joint which can be readily replaced and connected to the medical instruments; and a me...

A cleaning machine operating with granules having a pump for ejecting liquid optionally with or without granules which are heavier than the liquid, through nozzles against the goods to be cleaned in a treatment space (10) connected to the suction side of the pump via a bottom outlet (11). A granule valve having a socket (38) open at each end thereof is associated with the bottom outlet, said socke...

Electrostatic coating methods and apparatus are used to coat the exterior surface of glassware and preclude deposition on the interior surface and mouth of the glassware. A preferred stearic acid coating electrostatically applied over glassware with a hot end coating provides a more durable coating, improves scratch resistance and can reduce the amount of hot end coating for improved scratch resis...

The hydrolysis of carbonyl sulfide is substantially improved by utilizing titanium dioxide particles as a catalyst. It is especially favorable, if the titanium dioxide particle are sintered and treated with sodium hydroxide or sodium aluminate. Through such a treatment, the catalyst can be regenerated and reutilized.

A particulate resin mixture for the manufacture of grinding wheels, clutch and brake linings, moulding compositions, as well as for use as reactive hot-melting adhesive for connection points which are subjected to high thermal and mechanical stress, comprise a particulate resin wherein at least a proportion of the particles comprise a cure accelerator for the system. The resin may be a phenolic no...

A method of producing cartons of packets of cigarettes, whereby a blank, folded in a U about a respective group of packets so as to leave three exposed surfaces from each of which at least two tabs of the blank project outwards, is finish-folded, over at least one of the exposed surfaces, by a respective single folding head having a folding device for each tab, and which provides for folding the t...

The device can be connected to a telephone line, present in the area being contacted, via a socket 1 which, via the line 2, brings the signal to an interface 3 able to receive and transmit data in the network. Via line 4, the signal arrives at a programmable counter 5 to count a particular number of rings. Upon reaching this number, the device goes into an alert state ready to carry out three func...

In a device for activating the rotation of a step (1) for vehicles such as, for example, camper vans, caravans, etc., comprising an upper step (2) secured to guides (3) in which a lower step (4) is engaged slidingly, the guides (3) are connected so that they can rotate to a shaft (5) rotationally driven by motorised means (6) which are fixed to a support (7) secured to the vehicle. Wedged onto the...

A uniform layer of "Plastisol", or the soft paste obtained by mixing PVC with known additives and other components is transported at constant speed on a belt of silicone-treated cellulose paper or other suitable material which is transparent to microwaves through a tunnel stove with combined heating (hot air and microwaves) which is equipped above to generate a continuous flow of hot air in counte...

An armchair or the like having arms (4) made integral in cantilever with front legs (1a) through means (3) of articulation equipped with means (7) of adjustment of the relative friction, the opposite free end of such arms supporting back (8) through means (13, 9a, 11) with adjustable friction, such articulating (7) and hinged (13, 9a, 11) means being capable of allowing the suspension of arms (4) ...

Cross-linkable fluid compositions capable of providing glasses having a high refractive index derived from reaction mixtures which comprise norbornene derivatives of the type (A) in which R and Re, which are the same or different, are H or the CH3 group, X is an atom of O or S, and polymercaptan compounds of general formula C(R3)(n- n1-CH?-OOC-(CH2)?-SH3n (B) in which n lies between 2 and 4 and m...

Polymeric compositions based on copolyamides, having high impact strength, in particular at low temperatures, and high fluidity in the molten state, comprising: (C1) a copolyether amide (C2) an at least partially functionalized olefinic and/or diolefinic polymer, and (C3) possibly, a non-functionalized olefinic and/or diolefinic polymer. i
