A tool-operated latch has a body which is mountable on the back side of a door panel adjacent an elongate opening and a hole formed through the door panel. An elongate latch lever is pivotally carried by the body and is movable between a latched position wherein the latch lever is nested with respect to the elongate door opening, and an unlatched position wherein the latch lever is extended with r...

A dual deadman timer circuit functions to reset a dual mode microprocessor in the event of loss of program control. The microprocessor has high and low power requirements corresponding to its two operating modes, and the deadman timer circuit also adjusts the output power level of an associated two-level power supply to ensure that sufficient power is available for the full operation of the microp...

An electronic up-down counter system including a directional discriminator for accepting input pulses and for generating sequences of pulses which represent up-count and down-count signals. The count signals are applied to a reversible up-down counter having separate inputs for up-count pulses and down-count pulses. The directional discriminator is embodied in a read-only memory (ROM), which accep...

PURPOSE:To detect a fault of an interface, by storing the standard specifications of the interface, detecting the operation of the interface corresponding to said standard specifications to perform a collation and discontinuing the writing of the latest information to a recording part in case a different operation is detected. CONSTITUTION:The standard specifications of an interface are stored in ...

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...

The shell is removed from a crustacean by creating a pressure difference across the shell. Initially the crustacean is heated until body liquid adjacent the shell is just below boiling point. The pressure on the crustacean is then suddenly lowered to induce the liquid to boil and thereby create the pressure difference across the shell. After pressure treatment, the crustaceans are projected into a...

An electronic control system for a motor vehicle friction clutch and which has an engine speed sensor, a reference signal generator, and a clutch actuator responsive to an error signal E derived from engine speed and reference signals V1 and VR respectively. The error signal E is fed into an integrator having two operation modes, dependent upon whether a capacitor in the integrator circuit bypasse...

A hydraulic cement mortar comprising uniformly dispersed reinforcing fibrillated plastic filaments having microfibrillated structure and elements manufactured therefrom have improved mechanical isotropic properties, such as enhanced performance regarding their semi-elastic limit and impact loading characteristics. It is disclosed also the process for manufacturing said elements.

Additives for cementitious materials are formed from mixtures of (1) salts of naphthalene or lower alkyl substituted naphthalene sulfonic acid formaldehyde condensates and (2) water-soluble resins selected from the group consisting of resorcinol- formaldehyde and catechol-formaldehyde resins. Addition of these mixtures to cementitious materials results in improved slump and compressive strength.

A polymer composition is disclosed and consists essentially of 100 parts by weight of an ethylene-alkyl acrylate copolymer and about 1 to 5 parts by weight of a polymer of a higher alkyl ester of acrylic or methacrylic acid. The polymer compositions have a lower heat seal strength than the ethylene-alkyl acrylate copolymer contained therein.

A method and apparatus for regulating the intensity of the catalytic conversion of hydrocarbons in a conversion system employing a transfer line reactor are disclosed.

Discontinuous cellulose fibers are treated to improve their dispersability into a matrix comprising plasticized vinyl chloride polymer. The treatment includes contacting the fibers with a mixture of an aqueous dispersion of a vinyl chloride polymer and a plasticizer so as to coat the fibers, and drying the fibers. The non-aqueous portion of the mixture is usually present in an amount of at least 2...

Resins are prepared from polysulfone and polyethersulfone polymers that bear functional groups derived from compounds that are condensation products of amino-phenols and acid anhydrides. The polymers are prepared by coreacting aromatic compounds holding two hydroxyl groups, aromatic compounds holding two active halogen groups, and the condensation product of amino-phenol and acid anhydride, the co...

Removal of ambient oxygen from aqueous liquids is effectively catalyzed by enzymatic deoxygenation systems comprising alcohol oxidase in the presence of alcohol optionally with catalase. Suitable deoxygenation systems described can be used to alleviate corrosion and oxidative degradation in areas such as oil field fluids, circulating water systems, water storage tanks, alcoholic beverages and food...

An aqueous petroleum resin emulsion is realized by the slow addition of part of the water with vigorous agitation to a resin blended with up to 10 weight percent resinplast and in the presence from 3 to 10 weight percent of an emulsifier until inversion and thereafter adding the balance of the water at low agitation and thereafter cooling said emulsion to a temperature at least about 20 DEG C. be...
