A contour skirt for mattress pads or covers and the like is provided with a high friction inner surface to hold the pad or sheet firmly in place on a mattress. Foam material such as polyurethane may be stitched to the inner surface of the skirt in a pattern that produces "puffs" of foam that act as "treads" to grip the mattress. Alternatively, high friction polymeric material such as latex or neop...

The material has a density of 0.1...

A high temp. coating for esp. porous ceramic substrates comprises (a) a (prim.) barrier layer of compsn. (by wt.) 90-99.9% quartz glass and 0.1-10% silicon tetraboride (contg. more than 96 wt.% SiB4); and (b) a (final) emissive enamel layer of compsn. (by wt.) 95-98.5% high silica content glass and 1.5-5% silicon tetraboride (contg. more than 96 wt.% SiB4). Also claimed is a process for providing ...

Fluoride glass optical fibres are fabricated by minimizing the number of high-temperature operations. A tube comprising an external layer of a first fluoride glass of composition suitable to form the cladding of the fibre and an internal layer of a second fluoride glass of composition suitable to form the core of the fibre is prepared from a melt by a conventional rotational casting technique. The...

This invention provides the following resin composition, method for producing the composition, resin slide material, organic solvent resist material and glass fiber reinforced composition obtained therefrom. A polycarbonate/polyolefin based resin composition exhibiting an improved polycarbonate/polyolefin compatibility prepared by melt kneadin (A) a polycarbonate resin; (B) a polyolefin resin; (C)...

This relates to a non-human transgenic mammal characterized in that all its germinal and somatic cells contain the nucleotide sequence coding for human interleukin-6 (hIL-6) - under the control of a liver- specific promoter - introduced into the said mammal or into a foetus of the said mammal at an early embryo stage in its development. Very satisfactory results have been obtained when the liver-s...

An elastic metal clamp for joining two coaxial tubes is described which provides a secure tightening and is characterized by a strip (1) which has two indentations (8,12) through which tightening is achieved by using a tool, a further identation (11) which, latching by means of a tongue (5) formed in the strip (1) achieves, when tightened, the fixing of the clamp onto the two coaxial tubes.

A description is given of a fast-locking metal wire clamp for securing gaskets, particularly suitable for washing machines. This clamp is extremely simple to make and fit and is absolutely reliable.

A metal case is described for metal screw clamps used for joining coaxial pipes. This case is obtained by shearing sheet metal and is formed by simple bending of its mating parts.

A method and equipment have been developed for reproducing on an edible medium 10, with dyes for food use, an image printed on an inedible medium 1 such as a paper medium or the like. Suitable edible media are rice paper and sheets made from pastes similar to those used for the production of wafers and the like. (Fig. 1)

In a plant for the continuous treatment of metal strip in a bath, the strip N passes through a series of successive tanks V while it is made to pass tensioned along and around a series of rollers arranged in alternate manner outside the tanks (rollers RS) and inside them (rollers 24) immersed in the treatment bath. According to the invention, the residence time of the strip in the bath is varied b...

This invention concerns a mechanical transmission for drive wheels, of self-propelled machine tools in particular.

A gas tank evacuator (10) comprises an evacuator housing (12) into which a neck (80) of a gas tank (82) can be screwed and an elongated valve-removal rod (14) for slidably passing through the evacuator housing and engaging and unscrewing a stem-actuated valve (88) of the gas tank. An elongated valve actuator pin (18) slidably passes through the valve-removal rod to extend from lower and upper ends...

A child restraint is used with a chair having a seat and rear legs. The restraint has a base strap that is connected to the rear legs of the chair using loops at either end of the base strap and buckles for closing and adjusting the length of the loops. Two shoulder straps extend upwardly from the base strap, at the back of the chair and over the shoulders of the child to be restrained. The should...

Adjustment of S concn. in a sulphate pulp mill by removing it from the chemical recovery loop comprises removal from black liquor in the form of sulphurous odour gases. The latter are passed into a power boiler to be burned. CaO produced in a lime kiln is added in an amt. such that the 5 cpds. generated from the odour gases and CaO react forming CaSO3 and CaSO4. They are removed from the flue gase...

Cellulose pulp is treated by (a) treating a pH 2-7 (the acid stage) for at least 10 sec. so that the fibres reach pH 2-7; (b) washing or pressing the pulp; and (c) bleaching the pulp in a multistage sequence at 80-120 deg C in each stage, including at least one peroxide bleaching stage after step (b).
