Phenolic foam products are fabricated from phenol-aldehyde resol; a blowing agent; a condensation catalyst; a cell control agent; and an allyl ether of methylol-substituted phenol wherein the said allyl ether is present in a range from 0.5 to 25 percent by weight of the phenol-aldehyde resol. The function of the allyl ether is to overcome the extreme friability of the phenolic foam system.

A method for generating prime powder from a material having a high melting point and apparatus for generating the powder is taught. The apparatus includes a melt delivery tube. The melt of the high melting material is introduced into the tube and exits from the tube into an atomization zone. Gas is delivered to the zone at high pressure as a stream to atomize the melt. Pursuant to the present inve...

An apparatus for atomization of high temperature melts to from very finely divided powder. The apparatus has a ceramic central melt delivery tube. Melt is introduced at the top and exits at the bottom. At the exit surface a high velocity gas impinges on the melt to atomize the melt into fine particles. The bottom portion of the melt delivery tube has an internal shape to expand the external config...

In atomizing a body of molten material having elevated melting point by directing the molten body as a stream into an atomization zone and directing a stream of atomizing gas into said stream to atomize and disperse it, the orifice from which the gas is delivered is positioned closely proximate the surface of the stream to be atomized, e.g. less than 0.45 inches way. A large percentage of fine par...

The method of producing fine powder molten metal comprising providing a source of the molten metal to be atomized, delivering molten metal from said body to an atomization zone through a melt delivery tube, the portion of said delivery tube which is exposed to said atomization zone consisting essentially of boron nitride, directing a stream of atomizing gas against said stream in said zone to atom...

A heat-curable adhesive composition comprising a mixture of substantially solid particles of a first reactive component with separate substantially solid particles of at least a second reactive component, the first and second reactive components being capable of reacting together to effect curing when the composition is heated to the curing temperature and the particles having a size distributuion...

Curable fiber resin matrix composites comprising epoxide prepolymers and organic polyamines modified with a heat- and moisture-resistant resin to control flow and tack are disclosed. The cured fiber resin matrix composites exhibit high toughness combined with excellent hot/wet strength.

Improved fiber resin matrix prepreg fabrics are disclosed which are comprised of a first layer of reinforcing fabric coated with an epoxy resin composition and a discrete second layer of an epoxy resin modified with an elastomeric polymer. The discrete second layer is provided with a support comprising a gauze-like, lightweight fibrous mat or carrier of light-weight fibers that preserves the secon...

The disclosure relates to a brake actuating mechanism in which a brake applying member is urged to apply a brake by a heavy coil spring. To release the brake a pivoted lever acts on the brake applying member and is moved in a brake releasing direction by an electric motor driven lead screw on which there is a ball-screw nut acting on the lever. The ball-screw nut causes the lead screw to spin unde...

What is disclosed is a foamable polymer composition comprising (A) a copolymer of 20-99.99 percent by weight of a member selected from the group consisting of acrylic acid and methacrylic acid, 0-79.99 percent by weight of a further ethylenically unsaturated monomer copolymerizable therewith, and 0.01-5 percent by weight of a member selected from the group consisting of metal salts of acrylic acid...

A microprocessor based sequence controller is for a soup and beverage vending machine 10. The microprocessor has two storage sections, one of which is not alterable and contains the basic program for the vending machine. The other section is alterable and contains modifications of the basic program entered from a separate service module, which is not normally connected with the controller during n...

Measurement taking is carried out by the detection of a chosen parameter at an appropriate depth in a borehole, and includes the step of the transmitting to the surface, via a suitable channel of a valuable succession of measurements, each of which has two characteristics, the first being an indication of the value of the parameter, whilst the second is independent of the parameter, in a technique...

Its hollow drive gear 9 meshes with the internal teeth 8 of a tubular wheel 4 whose external teeth 10 engage with the internal teeth of a ring gear keyed on the secondary shaft 13 of the reduction gear. The said tubular wheel 4 is guided by at least one internal roller 19 mounted to rotate freely on a spindle 20 carried by the casing 1 and by two external rollers 18, 19 which roll on a peripheral ...

A hazardous ammonium jarosite based sludge is solidified by the addition of cement and fly ash under mildly basic conditions, pH 10+/-1.5. The ammonia does not have to be driven off prior to solidification.

A process for the production of foamed films of polyethylene or ethylene vinyl acetate copolymers using metal salts of aliphatic fatty acids as additives.

An apparatus for dressing and adjusting a dished or plate-shaped grinding wheel at a tooth flank-grinding machine for a gear has an adjustable grinding wheel support at which there is mounted the grinding wheel, and a dressing carriage which is adjustable radially with respect to the grinding wheel. Arranged at the dressing carriage diametrically opposite the work location at which there is effect...

Compensation points are provided both on the encapsulation and on the inner conductor on identical region sections of the connecting cable. A length compensation point (1) is provided on the one hand and a jointed section (2) having two bending points.
