Abstract: A chemical calculator providing rapid and convenient ways to retrieve information and perform calculations of chemical elements and chemical formulas obtained by direct entry from a periodic table keypad. Chemical element data, such as atomic number and mass, or calculated data (e.g. bond distance) of element pairs are displayed on an LCD or CRT screen when element keys are selected. Chemical formulas can be written when element, numerical or formulaic keys are pressed. The "Enter" command results in the display of the chemical formula's condensed formula, formula weight and percentage composition. Other function modes permit additional transformations, reaction yields and limiting reactants and empirical formula determinations.

Abstract: A disposable sterilizer mechanical air removal test pack comprising an outer container in the form of a box having a definite shape and being formed of a relatively air and steam permeable material coated with a form-stabilizing layer of a relatively air and steam impermeable material, and a body of relatively air and steam permeable material enclosed in the box. An indicator means is arranged in the body of material for indicating when contact with steam has taken place. The box includes a plurality of closure flaps which provide interruptions which control and direct the flow of steam into and air out of the interior of the body of material with the flow of steam and air occurring predominantly in a lateral direction through the body of material.

Abstract: The disclosed invention is directed to a method of restoring a tooth with a light cured composite which comprises utilizing a light transparent impression or matrix which constitutes a negative reproduction of the occlusal surface of the tooth. The matrix is made by contacting the tooth surface with a polymeric impression material which when cured is light transparent and flexible. The polymeric impression material is allowed to set and then is stripped away from the tooth surface. A cavity preparation is then made in the tooth surface and treated in the usual manner. A light cured composite is then injected into the cavity preparation. The previously formed matrix is then placed over the light cured composite and pressure applied to the matrix. The composite is then cured by exposure to photopolymerizing light which passes through the transparent matrix. Following light curing, the matrix is stripped away from the tooth surface leaving a restored tooth with the original occlusal anatomy reproduced.

Abstract: Monosodium phosphate is highly soluble in water and can be used as an ingredient for a low pH liquid buffer in a concentration of about 13-40 percent by weight. Tri potassium phosphate has good solubility in water and is a suitable ingredient for a high pH liquid buffer in a concentration of about 20-50 percent by weight. By a combination of these two ingredients, a system has been developed for using liquid buffer mixes in place of solid phosphate buffers, especially for use as a direct textile bath additive.

Abstract: An elastomeric dental impression catalyst composition for mouth temperature curing of liquid polythiopolymercaptan polymers comprised of propionic acid-treated, submicron zinc oxide and purified benzothiazyl disulfide (2,2.sup.1 -dithiobis-(benzothiazole)) is disclosed. The composition contains at least 20 parts by weight of the propionic acid-treated, submicron zinc oxide and less than 20 parts by weight of substantially pure benzothiazyl disulfide, with the amount of each of the zinc oxide and the benzothiazyl disulfide being based upon 100 parts by weight of the polymer. The final cured composition is also disclosed.

Abstract: Steel alloys having improved mechanical properties and improved ambient and low temperature toughness following the repeated thermal exposures necessary to fuse and bond ceramic or glass coatings thereto have been prepared. Phase transformation temperatures are controlled by a critical combination of manganese, silicon, and optionally, nickel, in a steel alloy of silicon, carbon, aluminum, titanium and/or niobium, phosphorus, sulfur and iron. The resulting steel alloys have good glassability, and even after glassing demonstrate excellent yield strength, ultimate tensile strength and impact strength at both ambient and low temperatures (-20.degree. F.).

Abstract: This invention discloses an improved dental pulp capping and cavity lining composition which is successful in capping and preserving the vitality of moderately inflammed, as well as normal, healthy dental pulps and also serves as an acid resistant, protective cavity liner. This composition is prepared by reacting suitable phenolic derivatives with formaldehyde or its polymer, under carefully controlled conditions, to form a low molecular weight polymer condensate, which is first purified and then compounded into a two-paste composition of optimized utility. In use, one paste portion, containing the condensate, reacts with the other paste portion, containing calcium hydroxide, to yield after mixing a solid protective layer of set material, which facilitates healing of the pulp and formation of secondary dentin.

Abstract: A method of platinizing and heat treating tantalum metal is described. The platinizing of tantalum is accomplished by placing a piece of conductive corrosion resistant metal and a tantalum workpiece as electrodes in a platinizing solution. The electrodes are connected to a source of DC power supply and when the current is passed, platinum black is deposited on the tantalum workpiece. The platinized tantalum workpiece is then placed in a furnace maintained at a temperature of about 1050.degree. to 1150.degree. C. for a time sufficient to diffuse the coated platinum into the surface of the tantalum core. The method of using the electrode for the detection of faults in a glass lined apparatus is also disclosed.
