Patent number: 4966619Abstract: An apertured dead plate insert fabricated of a contact material, preferably graphite, and a correspondingly apertured dead plate subplate together constitute a dead plate assembly which is used in the hot end process area of glass bottle manufacture. The assembly can be easily repaired by replacement of the contact material insert. Use of the dead plate assembly reduces damage to hot formed glass bottles and results in increased production rates. The dead plate subplate is a rigid plate with a planar depression having an area corresponding to the area of the insert defined on one face by mounting lugs and an area of increased height on the other face corresponding to the area of the depression so as to provide a heat sink for the subplate in order to keep the insert at a relatively constant temperature variant during passage of air therethrough.Type: GrantFiled: May 31, 1989Date of Patent: October 30, 1990Assignee: Union Oil Company of CaliforniaInventor: Shelby M.

Patent number: 4477373Abstract: The products of a molten salt combustion of hazardous wastes are converted into a cooled gas, which can be filtered to remove hazardous particulate material, and a dry flowable mixture of salts, which can be recycled for use in the molten salt combustion, by means of gas/liquid contact between the gaseous products of combustion of the hazardous waste and a solution produced by quenching the spent melt from such molten salt combustion.The process results in maximizing the proportion of useful materials recovered from the molten salt combustion and minimizing the volume of material which must be discarded. In a preferred embodiment a spray dryer treatment is used to achieve the desired gas/liquid contact.Type: GrantFiled: June 4, 1982Date of Patent: October 16, 1984Assignee: Rockwell International CorporationInventors: LeRoy F.

Patent number: 4437980Abstract: A carbonaceous material is subjected to a hydrotreating process in which it is desulfurized, deasphalted and demetallized by reaction with hydrogen in a molten medium in the presence of potassium hydroxide and water. The water is present in an amount sufficient to minimize the formation of gaseous hydrocarbonaceous products but insufficient to significantly reduce the effectiveness of potassium hydroxide as the hydrotreating agent. The process is characterized by producing a very small amount of gaseous hydrocarbonaceous products, desulfurizing the carbonaceous feed to the extent of at least about 80%, deasphalting the feed to the extent of at least about 60%, and demetallizing the feed to the extent of at least about 90%. In a preferred embodiment, spent potassium hydroxide is regenerated and recycled to the molten medium.Type: GrantFiled: July 30, 1982Date of Patent: March 20, 1984Assignee: Rockwell International CorporationInventors: Laszlo A. Heredy, Raymund P. Skowronski

Patent number: 4382393Abstract: An overdrive assembly is adapted to be retrofitted into an automobile between the engine and the automatic transmission. The overdrive can be retrofitted to most domestic cars and light trucks equipped with automatic transmissions. The overdrive can be retrofitted without modifying the automobile chassis and without introducing any additional controls into the automobile.The overdrive assembly includes a housing rotatable at the speed of the engine. This is accomplished by coupling the housing of the overdrive assembly to the engine. A gear assembly converts the rotation of the housing to a rotation of a gear in the assembly at a speed greater than the speed of the housing. The gear assembly may include a stationary sun gear, a planetary gear rotatable with the housing and a ring gear rotatable at a speed greater than the speed of the housing to provide the overdrive. The ring gear drives an impeller. A turbine is hydraulically coupled to the impeller to rotate at the speed of the impeller.Type: GrantFiled: April 21, 1980Date of Patent: May 10, 1983Assignee: Trans Auto Specialties, Inc.Inventor: Thomas C. Bowen

Patent number: 4314557Abstract: Drug dispensers comprising a flat body composed of a drug solute phase dispersed in a continuous polymer matrix phase in which the release rate of drug from the body is substantially constant and is controlled by the rate at which the drug solute phase dissolves in the continuous polymer matrix phase. Such control and constancy are realized by establishing specific correlations between the diffusion coefficient, dissolution rate constant, and thickness of the body.Type: GrantFiled: May 19, 1980Date of Patent: February 9, 1982Assignee: ALZA CorporationInventor: Santosh K. Chandrasekaran

Patent number: 4201466Abstract: In an elongate exposure assembly in a copying machine, an illumination cylinder is nested in an array of elongate rolls which cooperate with endless elastic belts to drive the cylinder and feed the originals and copy sheets around the same. The rolls are of minimum stiffness, but are nevertheless capable of acting to feed the sheets correctly by reason of one or more self-locating spreader plates arranged at appropriate positions along their lengths to hold the rolls locally in the proper relationship to each other. Each such plate is provided with a throat opening into the cylinder receiving opening to provide access for the sheets to be exposed.Type: GrantFiled: February 5, 1979Date of Patent: May 6, 1980Assignee: AM International, Inc.Inventor: Terry G. Seelenbinder

Patent number: 4181078Abstract: There is provided an improved automatic recirculating duplicator adapted for duplicating from a master or plate selectively onto one or both sides of paper sheets. It is characterized by a single printing couple. Sheets are fed from a paper table to a printing nip between a printing cylinder and an impression cylinder for printing on the first side and, through operation of a controlled gripping and stripping apparatus, the sheets are turned about the impression cylinder for collection with the printed sides down on a paper tray. The paper tray is then shifted to the feeding location normally occupied by the paper table, and the gripping and stripping apparatus is reset for feeding the sheets, now printed on both sides, directly to an exterior receiver.Type: GrantFiled: December 8, 1977Date of Patent: January 1, 1980Assignee: AM International, Inc.Inventor: William A.
