The thread splicing device in which the two overlapping and in line ends and combined pneumatically, holds the tips of the thread ends freely and uses two air jets to interweave them. Before splicing, the ends of both threads are reverse twisted, being clamped at positions spaced away for the thread tips, the two jets being spaced apart to produce the rotation. The thread splicing member (101) has...

PURPOSE:To prevent carbonization and sticking of a film and to cut efficiently a material having the film by cutting a synthetic resin film of the material having the film by laser light of weak energy then cutting the base metal by laser light of strong energy. CONSTITUTION:Only the film 8 consisting of a synthetic resin is first melt-cut by laser light L of weak energy in a method for cutting a ...

PURPOSE:To permit the shift operation only through the operation of a speed- change lever by setting the transmission side edge part of the outer wire of a push-pull wire into free state and connecting a clutch lever for connecting and disconnecting a main clutch onto the above-described edge part. CONSTITUTION:If the gear parts are not meshed when a speed-change shifter tends to move a slidable s...

The electrode stacks, formed of zig-zag packages of strip electrodes with interposed separator, are inserted through side openings into the cells, and the block casing is closed by welding on a side wall.

A simplified and economically constructed electrical solenoid or coil assembly that can be used in elevated temperature environments comprises a coil wound on a hollow bobbin (20) of thermoset plastics material received in a housing (12, 14) of similar material. The bobbin flange has a terminal attachment portion (25) carrying a pair of terminals (16, 18) encased in the housing and interlocked wit...

A rechargeable portable lead-acid battery for use in providing electrical power to portable devices such as lanterns and the like, the battery particularly including an improved container and cover, an improved battery post construction and an improved electrical assembly.

A process for making the surface of glass non-thrombogenic, by modifying the surface of the glass through chemical grafting, by means of molecular bridges, of polyamide-amino chains capable of forming a complex with heparin. The glass surfaces modified chemically in this manner are then treated with a heparin solution.

Poly(aryloxyphosphazene) copolymers are prepared having randomly repeating units represented by the formula: wherein R and R<1> may be the same or different and are selected from the group consisting of monovalent aryl radicals and substituted aryl radicals having the structure: wherein X is a substituent selected from the group consisting of alkyl, alkoxy, aryl, aryloxy, amino a...

A method for continuously producing needled, non-woven tubing by winding a web on a stationary mandrel, multi-needling overlying turns and frictionally driving the formed tube about the periphery of the mandrel. The mandrel is tapered to accomodate shrinkage of the tube and to assist ejection of the formed tube without application of longitudinal tension on the formed tube. The mandrel preferabl...

PURPOSE:To increase the braking force and suppress wear of a brake shoe and suppress heating of a solenoid by forming the brake shoe of a spindle motor into the same shape as the peripheral face of a rotor part and making the applied voltage to the solenoid lower at an attracting time than a holding time. CONSTITUTION:The contacting face of a brake shoe 34 is formed into the same shape as the peri...

A Nylon/ethylene vinyl alcohol copolymer (EVAL) blend for film extrusion as single layer film or in combination with other layers as laminates. The Nylon is the homopolymer of the lactam of epsilon -aminocaproic acid or a copolymer thereof with other polyamid-forming monomers. The Nylon has to contain less than 0,5% (wt) methanol soluble extract and preferably less than 0,05% (wt) methanol solubl...

PURPOSE:To obtain stabilized orientation and superior flatness, by a method wherein a film is oriented laterally while the temperature of the film is being risen gradually by specifying a thickness profile of the film to be offered to a lateral orientation process and a widening angle of a tenter clip at the initial stage of the lateral orientation process. CONSTITUTION:An amorphous film is orient...

An electromagnetic friction brake whose components are held in assembled relationship by pins which are received with a press fit within holes in an electromagnet and an end plate and which are received with a loose fit within holes in an armature. By virtue of the pins, an assembly gage may be used to automatically establish an air gap of desired width between the armature and the electromagnet w...

A coating composition for polyolefinic products, especially polypropylene films, consisting of a solution of a dry three-component polymer system comprising: a) a vinyl or vinylidene chloride copolymer; b) a polymer of (meth) acrylic ester(s); and c) a phenolic resin, terpenephenolic resin or mixtures thereof. The coated products are useful as packaging films having e.g. improved thermoseala...

In an aircraft multiple disc brake assembly, an excessive total brake torque can be experienced during favorable, dry, conditions. To limit the brake torque to a predetermined maximum, the plurality of conventional brake piston assemblies are modified to provide a pressure responsive surface area which is in an opposing relationship to the braking force. When a predetermined amount of braking torq...

Oxymethylene polymers (POM) are obtained in a granular form, by cooling a POM solution or dispersion, whose temperature is above the sintering temperature of the POM, to a temperature slightly below the sintering temperature of the POM, and extracting from the suspension obtained only those POM particles which show a grain diameter of more than 70 mu m. As solvent or dispersing agent as well as p...

For manufacturing molded and impregnated parts from epoxy resin compositions, a reactive epoxy resin is employed which hardens more slowly at higher temperatures (120 DEG to 180 DEG C.) than at lower temperatures (80 DEG to 110 DEG C.). The reactive epoxy resin composition is applied at the higher temperature and subsequently hardened at the lower temperature. According to the method of the in...
