Abstract: A filter (21) for removing flux from a hot heat transfer liquid-flux mixture. The heat transfers liquid-flux mixture is directed into a chamber (41) having a plurality of spaced, hollow members (64--64) through which a coolant passes. Upon being cooled the flux deposits on the surface of the members (64--64). The liquid, with substantial portions of the flux removed therefrom, then leaves the filter (21).

Abstract: The use of certain organic materials having non-aromatic carbon-carbon unsaturation is described in connection with photopolymerizable compositions containing aromatic sulfonium complex salt photoinitiators in order to minimize or eliminate the odor of organosulfur reaction by-products.

Abstract: A high pressure and velocity water drive pipe is provided having inlet and outlet ends. The outlet end of the drive pipe extends and is secured horizontally through one side of a generally cylindrical tank and terminates between 2 and 31/2 inches from the inner surface of the opposite side of the tank. The tank includes a lower gravity outlet having an effective cross-sectional area appreciably more than the effective cross-sectional area of the drive pipe outlet end and the drive pipe includes structure defining a venturi zone therein into which the outlet end of a seafood meat supply line opens.

Abstract: Motor oil compositions formulated for use as crankcase lubricants in internal combustion engines are improved by including in said motor oil a small amount of at least one C.sub.8 -C.sub.24 aliphatic monocarboxylic acid amide, resulting in reduced fuel consumption of said internal combustion engines operated with said motor oil.

Abstract: Compositions are provided comprising complex salts dissolved in liquid organic esters in amounts of at least 10% by weight. The compositions provide a concentrated liquid form of complex salt for use as photoinitiator in polymerization reactions.

Abstract: Liquid compositions are described which comprise certain sulfonium complex salts dissolved in oxyethylene-containing organic material. The compositions are dilutable with, for example, epoxides to form photocopolymerizable compositions.

Abstract: A portable traction device incorporating a simple and quickly-attachable frame adapted to be positioned on the frame of a patient transport cot for the application of traction force to a patient during transport. The traction device includes a base frame or U-shaped bracket member which fits around the frame of a cot and includes flanges thereon to mount the bracket member on either end of a transport cot. The bracket member has suitable guide sleeves therein and a U-shaped pulley bar is adjustably positioned in the guide sleeves of the bracket member. Adjustably positioned pulleys are mounted on the pulley bar such that through the use of appropriate slings, traction force may be directed to the limbs, pelvis or cervical neck regions of the patient being transported to provide a traction force to the patient during transport.

Abstract: The shell of a mollusk is caused to open as the mollusk is being conveyed through a heated rotary tube. The conveyor in the tube and spaced radially inwardly from the inner periphery of the tube moves the mollusk along the tube while enabling the mollusk to be subjected to steam created in the tube by vaporization of water.

Abstract: A self-tensioning wire reel comprises two flanges threaded together such that, when a brake shoe applies a braking force to one flange, the other flange is free to continue rotating. This rotation on the threaded hubs brings the flanges closer together, exerting a lateral force on the wire coil therebetween and thus keeping the coil sufficiently tight to prevent binding during the unreeling operation. The brake shoe is a resilient cylindrical disk applied to the outer rim of one flange when tension is relieved on the wire. The tightness of fit between the disk brake and the shaft upon which it rotates controls the frictional braking force.

Abstract: An edger blade uniquely designed to cut into the surface of the ground thus loosening a portion of the dirt, lifting the loosened dirt from the ground, and throwing the dirt to one side. The blade is adaptable for mounting on most home garden edgers powered by internal combustion engines. The blade has a central hub portion provided with a shaft hole adapted to permit the blade to be mounted on the edger shaft. Two arms extend from opposite sides of the central hub portion to form hoe portions that perform the hoeing operations of the invention.

Abstract: A radial piston pump comprises a housing having a drive shaft rotatably mounted therein and a pair of longitudinally spaced pumps each having a rotor thereof operatively connected to the shaft for rotation therewith. Each pump further comprises a pintle valve mounted in the housing and having a respective rotor rotatably mounted thereon for communicating fluid from an inlet of the housing to an outlet thereof. Each pump further comprises a plurality of circumferentially spaced and radially extending pistons secured thereon with each of the pistons having a cylinder reciprocally mounted on an end thereof for pumping fluid from the inlet to the outlet upon rotation of the rotor which is mounted in eccentric relationship relative to a chamber formed in the housing.

Abstract: The specification relates to a thickening composition containing a silicate, an ether or ester and a cellulose. The specification relates also to a process for thickening an aqueous organic system with this composition.

Abstract: Chain-extendible, sulfonated isocyanate-terminated polyurethane-type prepolymers are obtained by treating the prepolymers with a strong sulfonating agent selected from H.sub.2 SO.sub.4, SO.sub.3, CISO.sub.3 H, and mixtures thereof.

Abstract: Self-emulsified polyurethane or polyurethane-polyurea or polyurea latices formed by reacting an aromatic polyisocyanate such as a polyurethane prepolymer with a strong sulfonating agent selected from H.sub.2 SO.sub.4, SO.sub.3, ClSO.sub.3 H, and mixtures thereof, converting the sulfonated polyisocyanate to a sulfonic acid salt by reaction with a base, and mixing the polyisocyanate in water to obtain chain extension and self-emulsification thereof.
