Polyoxyalkylene surfactants for cellular foams can be prepared by reacting by free radical addition polymerization a polyoxyalkylene adduct, a cyclic nitrogenous vinyl monomer and an esterified unsaturated dibasic acid, obtaining a reaction product usable as a surfactant in the formation of phenolic foams, said reaction product comprising a major component useful for said phenolic foams and a mino...

Polyoxyalkylene surfactants for cellular foams can be prepared by reacting under free radical polymerization conditions a polyoxyalkylene adduct, a cyclic nitrogenous vinyl monomer and an esterified unsaturated dibasic acid in the presence of an organic or inorganic per-compound and a metal catalyst.

A wristwatch strap of leather or the like has a continuous non-porous barrier layer on the surfaces of the strap that contact the wrist of the wearer. The barrier layer consists of metal particles such as aluminum, noble metal or silver, having a particle size of 150 to 500 microns, preferably 200 to 350 microns, embedded in a matrix which consists of a synthetic resin. The barrier layer is effect...

In a parapet portion of a curtain wall, indoor side and outdoor side members of each panel unit mounted at the top of the curtain wall are connected via a connector made of heat-insulating material, and a damp-proofing sheet is mounted so as to extend between the indoor side member and a building body to form a heat-insulating damp-proofing layer, whereby the disadvantages that heat received by a ...

A pneumatic tire and a method of constructing a tire bead for the same, in which the tire has a bead portion which is reinforced by a bead core of wire running around the bead portion and the wire is housed in a circular elastomeric support which forms a cradle in which the wire is located. The bead can be made by winding wire around the preformed elastomeric cradle.

The tension arm position of a tape recorder is sensed and any change in position is added as a correction factor to the capstan tach or tape timer tach count generated during a reel tach period. To this end, the tension arm position signal is clamped to ground at the start of the capstan count. At the end of the capstan count, the tension arm position is sensed to provides a value that is proporti...

A rear ski-binding element comprises a heel-holding member carried by a plate pivoted about an axis at right angles to the top ski face. Lateral flanges formed on the pivotal plate are each adapted to carry a lateral packing member. Each packing member has a resilient inner wall which is capable of outward elastic deformation under the action of engagement of a ski boot. The rear ski-binding eleme...

The present invention relates to one component polyurethane foam compositions which comprise mixtures of prepolymers of a polyol and an excess of isocyanate; the usual adjuvants for polyurethane foams, an expanding gas under pressure and a polysiloxane compound with antifoam activity stored in a valved pressure vessel.

A dual microprocessor computing system is used to control an engine in a motor vehicle. Each system contains a Personality Programmable Read Only Memory (PPROM) containing system calibration data that is transferred from the PPROM to the read-write memories in the microprocessors. In order to identify each PPROM a byte of memory contains a check sum and a byte of the microprocessor memory contains...

An electrosurgical generating system including an electrosurgical generator; a handpiece (12) including an active electrode (14) connected to the generator for applying electrosurgical current from the generator to a patient; and an initialising device or circuit for making an initial determination as to whether the handpiece includes power changing switches (32, 34) for changing the level of the ...

A process of reclaiming clear PET resin from bottles and other containers is disclosed. PET resin contaminated with a hot melt type polyethylene copolmer based glue is treated with a chlorinated solvent and optionally subjected to azeotropic drying.

A combined brake cylinder/air reservoir device in which a relatively small, tubular-shaped piston in a positioning chamber is connected to a larger power piston having an application chamber on one side and a release chamber on the other side in which air is stored in place of separate reservoirs. A replaceable cylinder liner is provided to receive different-sized power pistons. During a brake app...

An electromechanically reciprocable load has a driving spring tending to displace it from a retracted position into a working position upon the release of a locking brake. The spring force is opposed by the countervailing force of an electric motor which, during the working stroke, is progressively reduced in keeping with the diminishing force of the relaxing spring. When the load includes a calip...

A movable disc for a friction type electromagnetic clutch/brake is designed for preventing the production of grating sounds from the movable disc. The movable disc includes a rotary armature being movable in a predetermined direction by the application of electromagnetic force, a friction material stuck onto one side surface of the rotary armature, an elastic member supported on one side surface o...

An electro-optical device for reading an information disc comprises an optical system which is movable relative to the disc by at least one electro-magnetic actuator. The optical system is supported by elongated members whose length is great relative to their thickness and which are pretensioned in the longitudinal direction by magnets which cooperate with each other via an air gap, enabling the u...

Silicone elastomeric films of 1 to 500 microns can be made by coating an addition-curable or dehydrocondensation-curable silicone elastomer composition on a coated paper which has a peeling resistance of no more than 50 g/cm, curing the composition, and then peeling the film from the coated paper. These thin silicone elastomeric films can be used for gas separation.
