Deforming of a workpiece wherein a workpiece is clamped between high friction and low friction surfaces and frictional forces are utilized to transport the workpiece over the low friction surface and into engagement with a die surface. Further, the forming of a projection, in particular a flange, on a plastically deformable member by flaring a portion of the member and by building up hydrostatic pressure in the member, including the flared portion, sufficiently high to place the member in a plas...

A rotatable turntable having a plurality of workholders spaced about the periphery thereof is indexed to advance each of the workholders successively through each of a plurality of work stations positioned adjacent the periphery of the turntable to assemble electrical components. A first part positioned in one of the workholders has the leading end of an insulated wire extending from a supply of wire welded thereto, after which the first part is indexed to another work station without severing t...

The sandal is made of a foam rubber or a foam plastic sole within which a central portion of a single-piece fastening strip of a non-moldable material is embedded. The sole is manufactured in a mold having lateral recesses for insertion of the fastening strip prior to the molding process.

Compositions and methods used to inhibit scale formation and/or the formation of solid scale forming salts comprises adding to water small amounts of a synergistic combination of nitrilotriacetic acid and a specific organophosphate.

A method for the homopolymerization of conjugated diene hydrocarbons or for the copolymerization of different dienes either with one another or with styrene-type monomers in order to prepare polymers or copolymers having a pre-set molecular weight, which comprises carrying out the homopolymerization or copolymerization of said hydrocarbons in the presence of an alkali metal catalyst, such as lithium, and a modifier obtained by reacting an alkali metal with a conjugated hydrocarbon and an organoa...

The present invention relates to anesthetic compositions containing 1,1,2-trifluoro-2-chloro-2-bromoethyl difluoromethyl ether and 1,1,2-trifluoro-2-bromoethyl difluorochloromethyl ether, and to the method of anesthetizing warm blooded air breathing mammals by administering an effective amount of each anesthetic composition.

Methods involve holding an array of semiconductor devices on a substrate by means of a polyester mesh screen and photoresist material. After the array of devices have been formed by photoresist and etch techniques from a slice waxed to the substrate, the photoresist material is removed from the array but not from the substrate surrounding the array. The polyester mesh screen is placed over and forced against the array and photoresist material while the wax is removed with a solvent. The solvent ...

The invention relates to machines and methods for use in forming attaching loops in generally longitudinal orientation at or from end portions of coil springs. A spring is supported by support means of a machine with an end portion to be looped projecting therefrom. The projecting portion is operated upon by means or tools to bend it away from the remainder of the spring as to form a loop and then impart a permanent set to a portion of the wire of the spring whereby to retain the loop in a desir...

A respiration assembly and methods, the assembly comprising only a few nebulizing and exhalation valve components, force-fit together and disposable after short usage. Air is delivered during the inspiration phase of the respiration cycle from a conventional respirator to the assembly in the form of a low pressure main stream flow and a high pressure nebulizing flow, the exhalation valve being closed by distending an expandable bladder under pressure. Nebulization occurs by discharging the high ...

An improved construction is disclosed which utilizes a frozen surface as a support means. The improvement comprises a thermal barrier interposed between the base portion of the construction and the frozen surface. The thermal barrier functions to stabilize the frozen surface by prevention of its thawing, thus maintaining support capacity. The thermal barrier can be of rigid plastic foam materials, such as polyurethane foam or a composite of said rigid plastic foams with other thermal insulating ...
