Filed:

Jun 14, 1999

Appl. No.:

09/332654

Inventors:

Steven S. Kendall - Howell MI

Assignee:

Genesee Polymers Corporation - Flint MI

International Classification:

B28B 736

US Classification:

264 39, 264 51, 264238, 264338, 106 3822, 10628753, 249115, 427133, 427235, 427236, 427353, 427387, 427421

Abstract:

A process for preparing a mold used for producing, for example, high resilience polyurethane foamed articles, comprises the step of spraying an aqueous release compound on the inner, article-contacting surface of the mold, the release compound including: an aqueous carrier; and a release agent which forms a release film on the article-contacting surface, wherein the release film is formed by evaporating a majority of the aqueous carrier. An aqueous rinse solution is gently sprayed on the inner mold surface after formation of the release film. The rinse solution, now carrying residual water, emulsifier(s) and/or contaminants, is mechanically removed via an air entrainment device before significant evaporation of the rinse solution has taken place.

Abstract:

The invention comprises processes for the production of useful fluid or grease from curable silicone compositions or silicone rubbers, preferably reclaimed or scrap silicone rubber. The processes involve the application of energy in such a manner that a un-curable silicone grease or liquid that contains essentially all of the original material is produced from curable silicone compositions and grease or liquid is produced from silicone rubbers. Suitable energy forms include thermal and mechanical. The fluid or grease produced by the processes are useful as raw materials for the manufacture of silicone products such as: antifoam compounds (defoamers), greases, conformal coatings or rubbers. The materials produced by these processes were unexpectedly found to have exceptional antifoam properties without requiring the addition of other materials or further processing. A second unexpected finding is that finely ground silicone rubber possesses antifoam properties and that grinding and extraction techniques can produce a silicone fluid with significant utility in foam suppression.

US Classification:

222 64

Abstract:

A proportioning system for creating admixture from diluent and concentrate comprises accumulators which are alternatively repetitively recharged so that one is always on-line. Recharging is controlled by a fluid system including a piston assembly for injecting a measured charge of concentrate into an accumulator being recharged. Diluent is introduced by opening and closing a valve from the diluent supply with the recharging being activated and terminated by level sensing switches associated with the accumulators. Electrical control circuitry and a stroke adjustment mechanism for the piston assembly are also disclosed.

Steven Scott Kendall - Howell MI

International Classification:

F41A 1700

US Classification:

42 83

Abstract:

An improved nipple, used with a percussion cap to ignite the propellent of a muzzleloader without significant ejecta from the nipple (back-flash), is disclosed. A check valve, preferably using a spherical actuator that is loosely retained within the valve chamber, is used to preclude back-flash. Use of a check valve and use of a relatively mild percussion cap (compared to primers) revealed a set of new problems that are solved by the disclosed device. Difficulty in removing spent caps, because of the lack of cap removing back-flash, was solved by flash chamber structure within the nipple adjacent to the cap. A tendency for the protective membranes of percussion caps to lodge within a nipple not having back-flash was cured by the use of an actuator retainer that directs the actuator to the side of the valve chamber during ignition. Ignition was improved by the use of a flash jet orifice and by the use of a directing actuator retainer. The disclosed nipple may be constructed so as to be exchanged for existing nipples in side-hammer, and in-line, cap-fired muzzleloaders.
