Foams having aspartase-producing microorganisms bound to the foam are made from polyurethane prepolymers which are capped with polyisocyanates, including diisocyanates, derived from methylene-bis (phenyl isocyanate) which is commonly known as MDI. These MDI based foams are hydrolysis resistant as compared to the previously used TDI based foams. The foams can be used to produce L-aspartic acid unde...

Polyurethane foams with excellent physical properties are obtained by using a catalyst composition of a tertiary amine and 2-ethylhexanoic acid.

Polyurethane moldings having an inhomogeneously colored surface with color contrasts in fiber-like distribution are made by incorporating colored fibers of a specified type in a polyurethane forming reactionmixture. The colored fibers must have a staple length of from 0.1 to 6 mm, a denier of from 0.1 to 25 dtex, and a coloring agent that does not migrate or dissolve in the polyurethane-forming ma...

An inexpensive power supply for an electconic control system or the like which is capable of converting a wide range of applied AC voltages into a regulated output voltage. A thyristor is coupled in series with an input terminal and a threshold device, such as a Zener diode, placed across the input terminals and paralleled by an RC circuit coupled to the thyrisor gate. Another capacitor is coupled...

A method and apparatus for use at the stage of a radial tire building process at which a tread and breaker, and sidewall rubbers, are added to the expanded carcass. A tread assembly is built, comprising tread rubber breaker and sidewall rubbers and is then located around the carcass which is then expanded into the tread assembly. A tread assembly former has a central portion expansible to bring si...

The present invention relates to apparatus for cutting carcasses, especially hogs. The apparatus comprises a knife to which is imparted an oscillating motion in the vertical direction. This is suitably accomplished by a ramming device arranged at one end of the knife with the knife being pivotably supported by a frame on its opposite end.

A pressure measurement sonde of the type comprising two piezoelectric detectors, one being used for pressure measurements and the other being used as a reference detector. The latter is used to compensate at least partly, the effects due to temperature variations. This sonde includes means for favoring the heat exchanges of said detectors with the surrounding medium and for substantially balancing...

An hydraulic brake actuator comprises opposed pistons which work in bore portions in a housing and fluid pressure in a pressure chamber urges the pistons in opposite directions to separate adjacent ends of a pair of brake shoes. A pressure proportioning valve controls communication between pressure spaces constituted by the pressure chamber. The valve is normally open to equalize the pressure in t...

The invention provides a novel method for the preparation of a foamed body of a vinyl chloride-based resin composition having a very fine and uniform cellular structure in a continuous process with outstandingly low costs. The method utilizes a binary volatilizable blowing agent composed of (i) a first volatilizable organic compound which is a halogenated or unhalogenated aliphatic hydrocarbon boi...
