Abstract: A composition is disclosed which cleans baked-on, carbonized sludges and varnish deposits from the internal surfaces of automobile, motorcycle and truck engines. The product comprises a mutually synergistic solution of selected cyclic compounds, aliphatic amines and water, preferably dissolved in a hydrocarbon or hydrocarbon and aliphatic lower alcohol fuel base. The solution or base product may be placed in a pressure resistant (aerosol) dispenser, and pressurized. When injected into an engine over a period of time, significant removal of deposited contaminants occurs, resulting in smooth and efficient engine operation and lower levels of unburned hydrocarbon fuel, carbon monoxide, and other air pollutants.

Abstract: An apparatus for inking or printing on the surface of an item, such as a badge or emblem, is described. The apparatus incorporates a number of sub-systems including: an apparatus for holding and positioning blank screen material; a laser ablation system for producing the desired hole pattern in the blank screen material to form screens; a print/ink station; a table assembly for supporting a plurality of labels or emblems and moving such labels or emblems sequentially to the print station; and an apparatus for moving the screens to the print/ink station. The apparatus also includes heater for drying the ink after the printing/inking step is completed. The apparatus for producing the patterns includes a laser, mirrors for moving the beam in the x and y directions, and optics for focusing the beam on the blank screen material. The inking station includes an ink tray, a reciprocating squeegee and blades for wiping ink from the leading edges of the squeegee after the squeegee passes over the pattern.

Abstract: Cardiomyoplasty can be performed without significant incisions by using muscle segments as patches to reinforce the defective myocardium. This method involves the use of a dilator to form an opening within the diaphragm to provide an opening through which to pass the greater omentum. The greater omentum is partitioned and brought to the myocardium via the opening in the diaphragm to serve as an extra blood supply. Muscle segments are then used as patches on the defective myocardium by implacing them between the greater omentum and the myocardium. This method is accomplished through the use of a needle shaped myoplasty instrument for obtaining the muscle segments and a specially constructed dilator for forming an opening in the diaphragm.

Abstract: An emulsion coater apparatus for filling a screen with emulsion is described. A head delivers pressurized emulsion onto and through holes in a screen. Squeegees located on either side of the screen are then drawn across the screen's surface so as to remove excess emulsion and fill any holes not filled by the high pressure head. The emulsion coater apparatus coats a screen in a single pass, thus making the coating process more efficient. Moreover, dispersing emulsion under pressure alleviates the need to degrease the screen, saving costs and minimizing environmental damage.

Abstract: Articles of play for use with the game of catch include a ball covered with a hook and loop fastening material and a multi-layer catcher's mitt with a front layer also covered in a mating material. The multi-layer mitt includes a rigid rear layer, a flexible layer, and front layer of a hook and loop fastening material.

Abstract: Granite-like plastics useful in all forms of molding and thermoforming are disclosed. The granite-like plastics include a multiplicity of particulates formed of a thermoplastic and thermoset plastic combination which are suspended within a clear or translucent matrix of the same thermoplastic material as the particulates. The particulates are maintained in suspension due to their isopynic density with the matrix. Of particular importance are granite-like acrylics that can be used in place of standard acrylics.

Abstract: An apparatus and method for irradiating PTFE particles to cause them to disintegrate into a powder includes a chamber into which the particles are fed continuously. The particles are simultaneously agitated using only air, irradiated with a beam of electrons and pulverized. The powder produced thereby is extracted using an air classifier.

Abstract: An infant pacifier with a diaphragm melody generator in which only when the infant holds the pacifier in the mouth and sucks or mumbles, a diaphragm switch of the melody generator is operated in order to permit the generator to generate melody. The present pacifier comprises a nipple part for being held by the infant mouth, a handle part for permitting the pacifier to be handled and a melody generator. The melody generator comprises a diaphragm switch for turning on/off the melody generator in accordance with the holding force and an electronic circuit board for generating the melody in cooperation with the diaphragm switch when the infant holds the nipple part of the pacifier in the mouth. The diaphragm switch is applied with conductive ink at its center and easily expanded and contracted by the holding force.

Abstract: Far infra-red ray radiating materials in which organic metal compounds or organic silicon compounds are used as radiating materials are disclosed. Examples of organic metal compounds which may be used in this invention are alkyl metal ester, alkyl metal chelate, alkyl metal acylate, metal chelated ester, metal alcoholate, and zirconium tetraacetylacetonate. Examples of organic silicon compounds which may be used in this invention are dimethyl dispoxy silan, and methyl triethoxy silan. The far infra-red radiating material manufactured by using the above compounds make it possible to express transparent color and have increased surface brightness, adhesive strength, and heat resistance, without lowering its standard of radiation rate in comparison with known radiating materials manufactured by using inorganic compounds.

Abstract: An improved water turbine which has a first rotatable cylinder having a water inlet hole and a plurality of nozzles, and a second rotatable cylinder having a plurality of rotating blades on the inner surface is disclosed. Water dropped from an altitude enters the first rotatable cylinder through the water inlet hole, where it is injected to the outside of the first rotatable cylinder causing the first rotatable cylinder to rotate. Water passing through the nozzles then strikes the rotating blades to rotate the second rotatable cylinder.

Abstract: An undergravel wet/dry trickle system utilizing mechanical, biological and chemical filtration is described. This system provides the advantage of compact size coupled with efficient purification and saturation level oxygenation of the water returned to the aquarium. Moreover, this invention relies on a simple manufacture which is less costly than any wet/dry trickle system previously known.

Abstract: A far infrared ray radiating transparent resin composition is disclosed. The composition is composed of a transparent resin and a far infrared ray radiating ceramic material. The ceramic material which is added to the resin in the amount of 1-30 weight parts, has an SiO.sub.2 purity of over 96.0%, and an average particle diameter of 0.1-15 .mu.m. The resin composition according to the present invention not only radiates far infrared rays, but also maintains transparency at an acceptable level. Therefore it can be applied to various products where the both transparency and extended freshness of food are required.

Abstract: The subject invention is a new type of silica gel and process for producing the same. The silica gel is the product of gelling alkali metal silicate with excess acid in aqueous medium containing a minute amount a polymerization modifier. The modifier and salts from the resulting gel are then leached with water before substantial drying effects have ensued. Spray-dried gel particles do not require the additional steps of aging or ammonia treating to achieve the desired result of high surface area and high pore volume. The gel can be produced to have various useful and unusual characteristics including the combination of high surface area, high pore volume, and a large average pore diameter.

Abstract: Compositions useful in forming intumescent coatings are provided. These compositions are based on a reaction between phosphoric acid, melamine and monoammonium phosphate, which renders the monoammonium phosphate substantially less soluble while retaining its low dissolution temperature. Intumescent coatings utilizing the above-technology are disclosed as is a method of manufacturing these coatings.
