Abstract: The method of measuring viscosity of a glass body, such as an optical preform related to at least its softening temperature, exploits the scattering effects the body introduces into a substantially monochromatic radiation passing through it; more particularly, the width of the spectral line due to Brillouin scattering is measured. The temperature of the body can also be determined by measuring the width of the line generated by Rayleigh scattering. The method is of particular interest for measurements on glasses.

Abstract: Flexible, soft objects such as ostomy pouches, wound dressings, bandages, diapers, etc. can be flushed down a conventional toilet by covering the article with a sheet of material which rapidly becomes slimy or exudes a slimy material on contact with the water in a toilet bowl or by adding such materials directly to the bowl.

Abstract: Polymerization of methyl methacrylate with initiator of perester salt of maleic acid is faster and better by providing bisulfite activator in water-in-oil emulsion form.

Abstract: The distributed temperature sensor employs an optical fiber as sensing element located in an ambient or near a body of which the temperature is to be monitored or measured. A source of light pulses sends into the fiber, pulses of predetermined duration. The backscattered radiation is collected for each pulse and the frequency spectrum variations in the backscattered radiation with respect to the incident radiation are analyzed. A computer obtains the temperature from said variations. The source and the spectrum variation analyzer are part of an optical time domain reflectometer which allows the temperature information to be associated with the information on the position of the backscattering point along the fiber.

Abstract: A composite film that is particularly useful in protective garments comprises a film layer of polyvinyl or polyvinylidine fluoride or copolymers thereof bonded to a film of polyvinyl alcohol polymer or copolymers thereof.

Abstract: An ostomy device for releasably connecting an ostomy bag to an adhesive backed label including a mounting member for connecting one of two coupling parts to the label. The mounting member comprises an expandable portion for facilitating displacement of the connected coupling part between a normal position and an expanded position. The expanded portion comprises a pair of accordion-like folds including an inner fold and a smaller outer fold. The connected coupling part comprises a rib portion having a deflectible sealing strip extending therefrom. The rib portion is connected to the mounting member adjacent the outer folds such that the sealing strip is positioned intermediate the inner and outer folds when the coupling part is in the normal position. The inner fold guides discharge from the stoma into the bag and away from the interengaged coupling parts. In an alternate embodiment, the mounting member is affixed to the label.

Abstract: A holder for receiving cards with electronically stored data or printed circuit boards. The holder has guide means to receive the card. The holder is provided with a connector with contact springs for contacting connection strips located on the card. One end of each contact spring is clamped while the other is free to move and make contact with the connection strips. The contact springs include the parts formed by bending and shaped so as to minimize pressure and friction against the connection strips of the card.

Abstract: An improvement process for the preparation of copper-containing methanol dissociation catalysts by precipitation of a copper-containing catalyst precursor, calcination, and reduction of the precursor, the improvement comprising conducting the calcination of the precursor in an atmosphere of CO.sub.2.

Abstract: Polyethylene terephthalate scrap material containing on its surface a chlorine-containing polymer such as, for example, polyvinylidene chloride or polyvinyl chloride, can be recovered and reused by melt-blending it with a polymer from a defined class of ethylene copolymers containing an epoxy group, and melt processing the blend in the same manner as virgin polyethylene terephthalate. The recovered and reprocessed polymer material has good physical properties and barrier properties.

Abstract: This invention relates to a hand held, totally integrated dispenser for mixing and dispensing two viscous components. The dispenser includes a hollow plunger within a generally cylindrical outer chamber. The hollow plunger has an open ended container attached to its proximal end. The hollow plunger is used to mix the two viscous components and as a dispensing nozzle.
