Abstract: A hardenable insert for use with a reversible track link in an endless track assembly to be interposed between the worn side of a used track link and a track shoe applied thereto. The pad includes a matrix which is formed of a deformable binder or filler material, an uncured resin flowable in its uncured state and rigid when cured. The resin impregnates the pad. The pad also includes a plurality of rupturable capsules dispersed throughout the pad, the capsules containing a curing agent for the resin so that when the pad is interposed between the worn side of a reversible track link and a track shoe, and the track shoe is clamped to the track link, the pad will deform to conform to irregularities at its interface with the track link and the capsules will rupture to cause the curing agent to cure the resin to rigidify the pad and thereby provide a smooth interface to prevent loosening of the track link and the track shoe during subsequent use.

Abstract: A stabilized and extrudable paste or gel dentifrice comprises two dentifrice portions, each of which includes a component which is chemically reactive with the other such component in the other portion, with the portions being maintained separate from each other in a dispensing container from which they are dispensable together through a closable opening therein in response to pressure. One of the reactive components is an alkali metal fluorine-containing salt such as sodium fluoride or sodium monofluorophosphate, used for its effect in hardening tooth enamel, and the other is a water insoluble calcium salt, such as dicalcium phosphate, tricalcium phosphate or calcium carbonate, used as a polishing agent. The dentifrice portions are preferably separated by an extrudable material, such as a polyhydric alcohol-water gel of a gum, such as sodium carboxymethyl cellulose. Also within the invention is a method for the manufacture of the mentioned dentifrice.

Abstract: A high-viscosity liquid is accommodated in a container whose outlet directly communicates with the intake port of a pump. The intake port communicates via a pump chamber with an outlet port of the pump, and an impeller having flexible blades rotates eccentrically in the chamber so that the blades wipe the surface of the wall bounding the chamber and pump liquid through the outlet port into a mixing chamber through which a water nozzle directs a stream of water which traverses the chamber and becomes mixed with the liquid to issue from an outlet of the mixing chamber as a completed beverage.
