摘要:
A modeling dough comprising gelled poly(vinyl alcohol), water and a filler provides a dough resistant to flaking, cracking, and crumbling. In the disclosed invention, the poly(vinyl alcohol) resin is gelled, thereby providing a water-based resin system that is not sticky yet very ductile. Prior to drying, the dough also exhibits the properties of bounceability and the ability to pick up newsprint. After the dough is air-dried, the poly(vinyl alcohol) resin serves to bind the components into a solid, durable product. The filler accounts for a large portion of the volume of the dough, so the overall volume is not greatly affected by water loss upon drying. The dough is water-based and easy to wash from skin, carpets, and other surfaces. Dyes and pigments can be easily incorporated into the formula. The dried product is sandable, carveable and paintable.

A game ball for playing baseball or softball, and the method for making the ball. The ball is formed of a hollow plastic shell filled with an expanded plastic material, and a cover completes the ball. The weight of the ball is provided by the weight of the shell, the expanded plastic filling the shell, and the cover. The COR, sound, and feel off the bat are provided almost entirely by the plastic shell. The material of the shell is an ionomer or a polyolefin, and the preferred material is an ethylene acid copolymer, the material for the shell being selected to have a hardness in the range of Shore D 30 to 65. The expanded plastic filling the shell may be any self-initiating material. The method for forming the ball is to mold two hemispheres, place a liquid mix for forming the expanded plastic into the lower hemisphere, weld the upper hemisphere to the lower hemisphere, the upper hemisphere having a vent hole at the top, and let the shell rest while the material expands to fill the shell. The cover is then placed over the shell to complete the ball.

A game ball and method for making the ball. The game ball is for use as a conventional, standard baseball or softball having the desired size, rebound and sound when hit. The ball includes a conventional preformed core of cork or the like, and a plastic shell covering the preformed core in lieu of the conventional windings. The conventional leather cover is received over the shell to complete the ball. The shell may be molded of 100% ionomer resin, or ethylene vinyl acetate may be added up to 25% to reduce the rebound, the ionomer resin and EVA being mixed together before molding the shell. The thickness of the shell is at least one-sixteenth inch to provide the desired rebound, and the shell is spherical with a diameter such that the covered ball will have the standard diameter. A liquid anti-bonding agent may cover the preformed core between the core and the shell, the anti-bonding agent being sodium oleate, silicone or urethane.

A vehicle protector utilizes a plurality of plastic sheets each having one surface thereof covered with a soft resilient material. The soft side of the sheets are disposed covering the outermost surface of the front fenders, the front door panels and the remaining side panels of a motor vehicle. The sheets are cut so as to have their marginal edges substantially conform to the marginal edges of the portions of the vehicle which they are adapted to cover. A pair of elastic bands straddle the front grille portion of the vehicle and are secured to the leading marginal edges of the pair of sheets covering the front fenders. Another pair of elastic members join the pair of sheets covering the front fenders, residing on the hood of the vehicle. Snap fasteners secure the trailing edge of the front fender cover sheets to the body of the vehicle adjacent the leading edge of the front doors. Another pair of sheets cover the front doors and are adapted with openings accommodating door handles and sideview mirrors. The cover sheets for the doors utilize snap fasteners to secure to the leading edge of the front doors and hook-like plastic members to secure the remaining marginal edges of the door cover sheets by capturing portions of the marginal edges of the front doors. A third pair of sheets cover the remaining side panels of the vehicle utilizing plastic hook-like members to capture portions of the marginal edges of the remaining side panels and a third pair of elastic bands, joining to each of the third pair of cover sheets straddling the rear portion of the vehicle.
摘要:
In accordance with the present invention, methods have been developed for the reduction of the chloride content of epoxy compound starting materials. Invention methods comprise fractionating an epoxy compound starting material into portions (e.g., fractions or cuts) having different chloride content relative to the epoxy compound starting material. Certain of these collected portions (i.e., the portions fractionated and collected after collection of the forecut and before discontinuation of the fractionation) contain substantially reduced chloride levels relative to the epoxy compound starting material.

A steering shaft lock for heavy-duty trucks having a steering shaft and accessible universal joint. The steering shaft lock has an elongated member and a flexible member attached to one end of the elongated member. The elongated member is steel bar-like member and the flexible member is a link-chain type member having one or more apertures or links. The elongated member is adapted to engage a spaced defined in the universal joint and protrude therefrom. The flexible member is adapted to lockingly engage the outer perimeter of the elongated member (at the point of its protrusion) with a locking device, such as a padlock. The steering shaft is locked by moving the flexible member toward the protrusion of the elongated member and placing the shackle of a locking device through one aperture of the flexible member and over the outer perimeter of the elongated member. Another method of locking is by moving the flexible member toward the protrusion of the elongated member, wrapping the flexible member around the elongated member near to its point of protrusion, and placing the shackle of a locking device through at least two adjacent apertures of the flexible member in a pinching relationship around the elongated member.
摘要:
A washable dry erase coloring composition comprising an acid dye or polymeric dye colorant, a dye vehicle, a release agent, and a dyeblocker additive. The dyeblocker additive is either a sulfonated naphthalene condensation product or a sulfonated phenol-formaldehyde condensation product. The dry erase coloring composition is suitable for use in marking on a whiteboard and enhances fugitivity from skin and fabrics. The dry erase coloring composition may optionally contain a film forming resin. More specifically, the invention is, in one preferred embodiment, a washable erasable whiteboard marker ink comprising an acid dye or polymeric dye, water, a film forming resin, a release agent and a sulfonated phenol-formaldehyde condensation product. In addition, the invention also includes a method of transferring an image from a whiteboard or non-porous surface to paper. This method comprises the steps of: (a) drawing an image on a whiteboard or non-porous surface with a washable coloring composition containing a dyeblocker; (b) applying a moistened paper to the image; (c) rubbing the moistened paper to transfer the image from the whiteboard to the paper; and (d) removing the paper.

Pan paints and associated color-changing systems are disclosed. In a first embodiment, the color-changing system comprises an undercolor pan paint coloring composition comprising an undercolor dye whose coloring ability is destroyed in the presence of a pH of about 10 or greater and/or in the presence of a reducing agent; and an overcolor composition comprising a colorant capable of maintaining its characteristic color in the presence of a pH of about 10 or greater and/or in the presence of a reducing agent, and a base such that the pH of the overcolor composition is about 10 or greater and/or a reducing agent. In a second embodiment, the color-changing system comprises an undercolor coloring composition comprising an undercolor dye whose coloring ability is destroyed in the presence of a pH of about 4 or less; and an overcolor coloring composition comprising a colorant capable of maintaining its characteristic color in the presence of a pH of about 4 or less and an acid such that the pH of the overcolor coloring composition is about 4 or less; wherein one or both of the coloring compositions is a pan paint.
