An electrosurgical generator, having particular utility in surgical procedures on human joints, is provided with an output impedance in the range of 600 to 2,500 Ohms in order to efficiently transfer energy to the high impedance joint. The relatively high output impedance permits much lower power settings to be empolyed than are required by conventional electrosurgical generators so that little or...

A flexible plastic sealing cover has a container cover area and pull-tab area. In one embodiment, an upper layer of plastic film is substantially impervious to moisture and bacteria. An orientated plastic film layer is bonded to the upper layer with a layer of adhesive, such that the orientated plastic layer promotes tearing when the cover is removed with the pull-tab. An adhesive material is bond...

A heel binding for ski boots cooperates with a boot heel plate for use in either alpine or cross-country skiing and includes a pivot member displaceable between locked and unlocked positions. In the locked position, during alpine skiing a forward shoulder on the pivot member engages the heel plate and resists upward thrust of the boot heel according to a selective biasing force as provided by a yi...

An absorbent floor cleaning composition is disclosed comprising shreds of a hydrophilic, open-celled, solids-loaded polyurethane foam having an aqueous phase releasably absorbed therein. The composition is particularly effective to clean flooring fouled with oily or greasy soils.

A molded polyurethane foamed shape has finely ground dry fire-retardant particles containing a volatile active fire-retardant component which releases fire-retardant gas when exposed to fire and distributed throughout the shape and encapsulated by the polyurethane so as to protect the component against evaporation until exposed by initial burning of the shape.

The process for the liquid-phase hydration of a vicinal alkylene oxide(s) to the corresponding alkylene glycol(s) comprising carrying out such hydration in the presence of a vanadate salt wherein the pH of the liquid phase is between about 5 and 12.

PURPOSE:To detect an address decoding error within a memory IC without increasing the hardware quantity by using effectively an idle area of the memory IC. CONSTITUTION:The 4-bit address signals A0, A1, A2 and A3 and parity signals P corresponding to signals A0-A3 are used to supply an access to a memory IC1. Such addresses where said address and parity signals are equal to odd parities are effect...

A device is disclosed which may be used by a person in the performance of a variety of exercises. The device includes in a preferred embodiment a substantially rectangular member pivotally joined together with an elongated member at respective ends thereof. The rectangular member is designed to be placed under a mattress so as to be retained thereunder by frictional forces as well as by the weight...

A tintable coating is applied to a transparent substrate such as a polycarbonate lens. The coating is made from a coating solution of (1) a further curable organopolysiloxane preferably made by hydrolyzing methacryloxytrimethoxy silane and vinyl triethoxy silane with phenylphosphonic acid, and an (2) organic solvent for the organopolysiloxane. The coating is cured, and azo dye applied to the cured...

A method of treating the surfaces of elastomeric unvulcanized molded objects or semi-finished products for use in further manufacturing; the surfaces are neutralized with a separating material in the form of unvulcanized powdery rubber. This produces a good neutralization and an improved product quality, especially with objects which are produced by vulcanization.

Cellulose acetate is formed into porous, spherical particles, having an acetylation degree of 49 to 60%, a particle diameter of 0.05 to 10 mm, a sphericity of 0.7 or larger, a pore volume of 0.4 cc/g or larger and a collapsing strength of 9 kg or higher.

Rubber compositions and metal-reinforced rubber ply members have improved metal adhesion and metal adhesion retention to brass and brass-plated metallic reinforcement. The improvement comprises admixing from about 0.5 to about 10.0 parts per hundred rubber (phr) of nickel molybdate, cobalt molybdate or a mixture thereof with a vulcanizable rubber composition prior to embedding the metallic reinfor...

Compounds of the formula wherein n is 0 or 1; A is methylene, vinylene or ethylene optionally substituted by lower alkyl; B is alkylene; R1 is an optionally substituted alkyl, phenyl or naphthyl group, or a cycloalkyl or pyridyl group; and R2 is hydrogen or acyl; and non-toxic, pharmacologically acceptable acid addition salts thereof. The compounds as well as their salts are useful as ...

A process for making a film of butene-1 homopolymer and copolymers of improved strength and clarity and the film made thereby. Such a film is produced by quenching an extruded poly(butene-1) homopolymer or copolymer while in the amorphous state, preferably at temperatures below 0 DEG C., and biaxially stretching the quenched film before substantial crystallization occurs. Subsequent heat setting ...

A weighing system for computing the prices of articles purchased by customers includes cards (4) containing codes for discriminating the customers. The card (4) is inserted in a card reader (16) attached to an electronic scale (1), and the prices of articles weighed by the electronic scale (1) are totaled for each of the codes of the cards (4).

A system for determining the stuck point of pipe in a borehole includes a wireline tool having an exciter coil and a detector coil axially spaced from one another. The exciter coil 61 is driven by an oscillator 81 at a preselected low frequency, and the resulting voltage induced into the receiver coil 63 is related to the magnetic permeability of a pipe 60 through which the tool is run. A detector...
