Splicing head operated by a compressed gas for use in an automatic splicing device for producing by splicing a thread connection without knots, having a splicing head with at least two openings to admit the compressed gas, which accepts the two threads which are to be joined together, and has the capability to effect the mutual tangling, interwining, mixing and/or winding around of the fibers of t...

A cotton candy making apparatus includes a hollow rotary member to be rotated, the rotary member being provided with a supply port for supplying sugar to the interior thereof and path for delivering molten sugar to a peripheral edge of the rotary member, a heating device located below the rotary member to heat the rotary member and hence heat and melt sugar in the rotary member, a fan for producin...

A specific elastomeric composition is formed by melt blending two particular elastomers, each composed of hard and soft segments made from poly(tetra-methylene ether) glycol, 1,4-butane diol and a phenylene dicarboxylic acid or a derivative thereof. The blend exhibits a melting endotherm that extends from no lower than 120 DEG C. to no higher than 215 DEG C. with a melting peak in the range of 15...

An illumination system for video inspection of transparent and translucent bodies to be inspected sequentially while moving along a conveying path has a light source and light-transmitting block partly enclosing over the end of the bodies moving on the path. A light source, especially one or more strobe lamps is located along the conveying path, and light from the source is directed inwardly by th...

An electronic apparatus such as a pocket computer is of the type in which a detachable memory module can be operatively coupled. Just upon interruption of power, the apparatus generates indefinite information such as random number, time information, or the serial number, so that the indefinite information is written into both the memory module and a memory of the body of the computer. Just upon ap...

A data processing system includes a cathode ray tube (CRT) display. Apparatus associated with the CRT tests and verifies the vertical and horizontal synchronization and the logic associated with the character generator by counting the various signal occurrences and comparing them with predetermined values.

POLYURETHANE FOAMS HAVING LOW SCORCH DISCOLORATION Polyurethane foams prepared with halogenated phosphoric acid flame retardant have low scorch and surface discoloration when prepared in the presence of a composition containing phenothiazine, 4,4'-thio-bis-(6-tertiary butyl meta cresol), and organophosphite.

This invention describes novel molded flexible polyurethane foam surfactants which can be used in foam having high concentrations of reinforcing graft copolymer solids. The invention also describes an improved process for making these foams using the novel surfactants.

A soft intraocular lens suitable for placement in the anterior or posterior chamber and either in or out of the capsular bag. The lens has a fenestrated haptic defined by an arcuate member including a tissue contact portion, beam portions and support portions which acting together keep the lens in contact with the eye during distortion and tend to cause the lens to vault posteriorly when compresse...

A differential limiting device is provided for use in a differential mechanism adapted to divide and transmit a torque from an input shaft to two output shafts. The device includes an oil pump driven by the difference in revolution speed between two shafts selected from the input shaft and output shafts, a wet clutch equipped with two types of disks and adapted to connect said selected two shafts ...

Thermosetting fluorodiepoxide polymer foams are made by mixing fluid form thermosetting fluorodiepoxide polymer components having a substantial fluorine content, placing the mixture in a pressure tight chamber, filling the chamber with a gas, at relatively low pressure, that is unreactive with the fluorodiepoxide polymer components, allowing the mixture to gel, removing the gelled fluorodiepoxide ...

Polyvinyl alcohol films are provided which are gelled, non-tacky, bubble-free and resistant to water at ambient temperatures. The polyvinyl alcohol film is obtained by plasticizing (fluxing) and melting granules of pure polyvinyl alcohol containing from 25 to 35% by weight of water at a temperature at least 100 DEG C. above the equilibrium melting point of the granules and less than or equal to 2...
