Abstract: The photochromatic indicator is a dry film comprised of microencapsulated chemistry which reacts to the degradation of the dry film components when irradiated by UVA and UVB in the frequency spectral range of 290 nm (low end of the UVB spectrum) to 365 nm (high end of the UVA spectrum). This degradation produces free hydrogen and chorine radicals which combine to form acidic byproducts of hydrogen chloride gas or hydrochloric acid.The initial microencapsulation has an interior molecular grouping of acid sensitive dye and UVA and UVB absorbing chemistry surrounded by, and bonded to, a chlorinated rubber compound. This interior is then also microencapsulated by bonding a coating of polyvinylchloride (pvc) to the chlorinated rubber by using epoxide agents which, in turn, retard the degradation of both the pvc and the chlorinated rubber.By varying the amount of epoxides in the bonding phase, the time for the dye to complete its full color change can be adjusted.

Abstract: This invention discloses a process for making a refractory filter for liquid ferrous and non-ferrous metal with improved priming action. A carbonaceous resin onto the surfaces of a hard-fired ceramic or refractory cloth filter for liquid metal which protects the filter against abrasion and the absorption of water and also holds and protects particulate additives in place on the surface of the filter where they can later react with the liquid metal. When the liquid metal approaches and then touches the surface of the filter, the resinous coating chars. The resulting porous layer of mechanically strong carbon retards heat transfer from the hot liquid metal to the otherwise unheated filter, aiding the priming of the filter and also controlling the rate of dissolution of the particulate additives into the liquid metal. The preferred resin has a high char-forming tendency and a mechanically strong porous carbon coating on the filter when the filter is exposed to the hot, liquid metal.

Abstract: A filter for molten metal with a particulate coating for simultaneously metallurgically treating and filtering is disclosed. A layer of particulates such as ferroalloy, deoxidizer, grain refiner, inoculant or master alloy is placed on the surface of a hard-fired ceramic or refractory cloth filter for treating liquid metal. The particles are held in place by a coating of carbonaceous resin which is applied to the surface of the filter and which also protects the filter and particles against abrasion and moisture. The placement of the particulate additives on the filter allows the molten metal to be metallurgically treated and filtered simultaneously.

Abstract: A sliced food article such as an onion, is quickly diced into a number of rectangular shaped pieces by forcing it through an upper and lower rack of parallel spaced blades such that the upper racks is at right angles to the lower rack forming a rectangular grid. The article, such as an onion, is forced through the rectangular spaces between the two racks of blades by a rectangular array of circular fingers depending from a plunger. The plunger slides along a pair of vertical guides towards and away from the blade. When the plunger is fully engaged with the blades, the free end of the fingers extend completely through the lower rack of blades. The base has four legs to give the device a steady foundation.

Abstract: A rounded food article, such as an onion, is quickly sliced into a number of slices by a manual device with a plurality of racks of parallel spaced tensioned blades mounted to the base at an acute angle. A transversing carrier assembly slides along guide rods in the base and is actuated by a pusher handle pivotally mounted to the base and pusher bar pivotally mounted to the pusher handle and the carrier assembly. The carrier assembly has a carrier plate and carrier fingers which are a parallel array of planor segments mounted above and parallel with the carrier plate and intermesh with the plurality of racks of blades. The food article is placed on the carrier plate and forced through the racks of blades by the carrier fingers, thereby slicing the onion into a number of slices. A guard mounted on the base shields the sharp edges of the blades.

Abstract: A rounded food article, such as a tomato is quickly sliced into a number of slices by a manual device with a rack of parallel spaced tensioned blades mounted to the base at an acute angle. A transversing carrier assembly slides along guide rods in the base. The carrier assembly has a carrier plate and carrier fingers which are a parallel array of planor segments mounted above and parallel with the carrier plate and intermesh with the blade rack. The food article is placed on the carrier plate and carried through the blade rack by the movement of the carrier plate and fingers, thereby slicing the tomato into a number of slices. A guard mounted on the base shields the sharp edge of the blades. With the carrier in the open position the rack of blades in combination with the carrier fingers and guard creates a vertical cavity in which the food article to be sliced is inserted.

Abstract: A rounded food article, such as a tomato or potato, is quickly divided into a number of radial sections by forcing it through a conical cup of radial blades within which it is impaled on a central spike to which the central ends of the blades are joined. The article is forced through the wedge-shaped spaces between the blades by an annular array of fingers depending from a plunger to which a handle is attached. The plunger assembly slides over a pair of vertical guides towards the blade assembly engaged within a recess in the base. The fingers extend completely through the blades when the plunger is fully engaged within the blades. The plunger includes obstructing tabs in the event both vertical rods are not properly engaged in the plunger, such that the plunger is angularly displaced and the fingers strike the base rather than the blades or spike. Four legs give the device a steady foundation and raise the base sufficiently from the table to allow the long food sections to be freely discharged onto it.
