A flexible polyurethane foam article with regions of different hardness is made by introducing into a mould a foam formulation giving a foam of a given hardness and then introducing a foam formulation giving a foam of different hardness directly into the first foam formulation at a time corresponding to a volume expansion in the range 100% to 2300%.

PURPOSE:To efficiently recover, from magnetic tape scrap, highly pure base plastic and magnetic powder, by treating the scrap of the magnetic tape that has previously been cut with an apparatus alkaline solution, and then stirring the scrap at a high speed. CONSTITUTION:After the magnetic tape scrap that has been cut by a tape scrap cutting machine 1 into pieces having a length of about 1-5cm and ...

Adhesive tape useful in supporting an array of parallel optical fibers in an optical transmission cable comprising an adhesive-covered biaxially oriented polyethylene terephthalate film having defined ranges for the proportion of gauche and trans conformations of the ethylene glycol linkages of the polyethylene terephthalate molecule, as measured by infrared spectroscopy, whereby extreme dimension...

The method of the invention comprises the following steps: - a strip of raw rubber, intended for building up tyres, is taken. - A layer of white or metallised paint-adhesive, compatible with the rubber, is deposited on this strip at selected locations, - glass balls are showered onto the layer of paint-adhesive, - the balls on the paint-adhesive are crushed and then the non-bonded balls are ...

In the case of a safety ski binding, the release spring is accommodated in a housing provided with an oblique guide. Interacting with this oblique guide is a sole plate which can be swivelled to a limited extent about a vertical axis and about a transverse axis and can be displaced to a limited extent in the longitudinal direction of the ski, the ski boot being held in the travelling position at l...

The invention relates to a safety ski binding toe mechanism comprising a skid plate underlying the forward end of the ski boot sole. According to the invention, the skid plate, or the pivotable and longitudinally shiftable sole retainer, respectively, is provided with keying means preventing the skid plate from twisting relative to the ski boot sole at least within the elastic yield limits of the ...

A pneumatic tire having, between two vulcanized elastomeric partitions, a layer of a sealing mixture arranged on the inner wall of the cavity of the tire, at least below the crown and from one shoulder to the other, is improved due to the fact that the layer of sealing mixture has a base of at least one vulcanizable elastomer of low molecular weight, preferably less than 30,000, contains at least ...

A pneumatic tire whose inner wall is provided beneath the crown with a lining which extends at least from one shoulder to the other of the tread and comprises a layer of a sealing mixture capable of flowing into a puncture hole, the layer being covered radially inward by a vulcanized elastomeric partition, is improved due to the fact that the layer of sealing mixture has a base of at least one ela...

The purpose of the invention is to enable, by means of a spring, both engagement and disengagement of a front drive dog clutch to be preselected. A hand-operated preselector 1 acting on a compression spring 8 affecting via a transmission mechanism a displaceable shifting sleeve 14 has both a stop 2 protruding into a recess of a fixed gate 4 and a recessed member 17 in its bottom part to receive th...

In a process for the thermal after-treatment of paste-forming homo- or copolymers of vinyl chloride, obtained by aqueous emulsion polymerization, followed by spray-drying to produce a spray-dried powder, an improvement is provided wherein 20 to 60 percent by weight of the spray-dried powder is warmed for 1 second to 30 minutes to a treating temperature of 75 DEG -110 DEG C., and then is recombine...

This invention relates to equipment which is installed in oil wells and more particularly to a tool control apparatus for a tool placed in the production string of a well. This apparatus is lowered into the well at the end of a cable (116). It comprises a first mechanism (134-148-152-154) for transforming a longitudinal reciprocating movement into an alternating rotary movement, the longitudinal m...
