This invention is a method of making a battery plate grid from a continuous sheet of expanded metal with a central unexpanded reservation 11 with slitted and expanded metal in portions of the grid 12 and 13 on either side of it. Transverse cuts are made at 14 so that the unexpanded reservation projects as a lug at one side of the grid and defines a notch at the opposite side. The grid can then be ...

A process for simultaneously disposing of refuse and producing a useful fuel or synthesis gas and an inert inorganic residue by feeding shredded refuse, from which ferrous metal has preferably been magnetically separated, and which has been compacted into hard pellets, into an oxygen fed pyrolizing, slagging shaft furnace.

Oxymethylene polymers (POM) are obtained in granular form by cooling a POM solution or dispersion having a temperature above the sintering temperature of the POM in two stages to a temperature just below the said sintering temperature. The solvent or dispersion agent used is a mixture of methanol and water and the cooling agent is a methanol/water mixture which may contain POM suspended therein. T...

PURPOSE:A process for preparing beadlike gels of a water-insoluble eta-1,3-glucan, used for carriers of fixed enzymes or in affinity chromatographies, gel permeations and ion exchanges.

By providing in a carcass saw an enclosure including at least one exhaustible receptacle for bone dust and other waste generated in the course of sectioning a carcass in a slaughter house, contamination of succeeding carcasses by such waste is eliminated.

The cylinder (10) is vented outwardly in the interior of the diaphragm cylinder by a vent (29) which allows the intrusion of dirt and moisture. The diaphragm cylinder interior is isolated from the guide tube interim (12) by an annular sealing ring or spaced rings (31) seated between the guide tube (12) and the piston rod (14) and sealing the annular chamber (9). The ring is rigidly seated either o...

A brake or clutch having two relatively rotatable members and a hollow fluid-distensible resilient annular tube frictionally engaging one of the members. The tube is split and the ends butted together. And at the butt ends of the tube means are provided for increasing the durability and life of the tube.

A vehicle differential mechanism having a rotatable input member (16) for connection with a drive means and a pair of rotatable output members (17, 18) one on each side of the input member for connection with components such as wheel-driving shafts (13, 14) to be driven by the mechanism. A pair of rotatable clutch members (19, 20) are located one on each side of the input member (16) between the i...

The subsurface position of a blowing well with respect to an adjacent relief well is determined by detecting at a plurality of axially and tangentially spaced locations in the relief well acoustic waves emanating from a subsurface location of the blowing well. The distance between the wells is calculated on the basis of the difference in times of arrival of the waves at said axially spaced locatio...

A method of preparing a polyvinyl chloride dry blend from solid vinyl chloride polymer dry blend grade resin particles, solid filler particles and liquid plasticizer in which separation of filler particles during processing is reduced by adding together with the plasticizer at least 0.2 part per 100 parts by weight of resin of a liquid cationic, nonionic or amphoteric surfactant.

This invention discloses an instrument package 20 for a drilling a unit which gathers the information from a pitch sensing device 52, a roll sensing device 53, and a 3-position magnetometer 51 along with a gamma counter 50, and converts the information to a multiplexed signal which is subsequently used to frequency modulate a pulse train. The pulse train is then transmitted down a long cable to a ...
