Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed an improved unitary sealing ring that is used on the shafts of rotating elements.  The ring has first and second axial faces.  The second face has a recess forming a flange therein.  At least one annular groove extends along the inwardly radially extending surface.  A first longitudinally extending groove communicates between the annular groove or grooves and the axial face.          A second longitudinally extending groove extends from the first face to the second face on the outer surface of said ring.  The annular groove or grooves function as an oil groove or grooves and the longitudinally extending grooves are designed to accumulate foreign particles that may be incursive with respect to the journalling means of a driving or driven device.  These foreign particles are then expelled to the second longitudinally extending groove due to the centrifugal force when the device is being operated.

Abstract: ABSTRACT OF THE DISCLOSURE:            A continuous process of converting non-ferrous metal sulfide concentrates to form a liquid phase which is rich in non-ferrous metal and a slag phase in an elongated horizontal reactor under a gas atmosphere which comprises S02-containing zones, in which concentrates of sulfides of copper, nickel, antimony, cobalt or lead or mixtures thereof and admixtures are charged onto a molten bath, oxidizing and reducing gases are blown into the molten bath, a phase having a high non-ferrous metal content and a phase having a low non-ferrous metal content are discharged at opposite ends of the reactor, the phases are caused to flow countercurrently in the form of substantially continuous layers to the respective outlet ends of the reactor, at least part of the oxygen is blown into the molten bath from below through nozzles spaced apart along the oxidizing zone of the reactor, the solids are charged into the reactor through a plurality of feeders, which are disposed at separate locations spaced apart along a considerable length of the reactor and are controlled independently of each other the locations and the rate at which oxygen and solids are fed are selected so that the oxygen activity in the molten bath has a maximum at the outlet end where the phase is discharged which has a high non-ferrous metal content and a low iron content, in order to promote the production of said phase, and decreases progressively in the reducing zone to a minimum at the outlet end where the slag phase is discharged which has a low non-ferrous metal content, in order to promote the production of said slag phase, gaseous and or liquid protective media are blown into the molten bath at controlled rates together with the oxygen in order to protect the nozzles and the lining which surrounds the nozzles and to assist the control of the processing temperature, and the rates at which gas is blown into the molten bath are controlled so that an agitation which is sufficient for an effective mass transfer is created in the bath whereas the layers formed by the flowing phases and the gradient of oxygen activity are substantially maintained.  The process of the invention is characterized in that the gas atmosphere in the reactor is caused to flow countercurrently to the slag phase and the exhaust gas is withdrawn from the reactor at the same end as the phase which has a high non-ferrous metal content.  The invention enables one to decrease the metal content of the slag phase, to improve  the utilization of heat in the reactor and to permit additional heating.

Abstract: ABSTRACT OF THE DISCLOSURE               The variety of technologies that have been applied in the development of a bonded grid cathode are described.  These include chemical vapor deposition of tungsten, molybdenum, iridium BN, and Si3N4 on both sides of a sintered tungsten cathode disk. Zirconium and titanium getters have been used to eliminate nitrogen evolution problems.  The getter plates are also used as heat shields for the bonded heater.  Films of Si3N4 have been added to the insulation to prevent calcium and barium diffusion into the layer and maintain adequate resistivity and breakdown strength. Plasma etching was introduced as a method of removing Si3N4 from the cathode pores.         A new method, erosion lithography, is used for making the fine-detail grid structure, combining air erosion and litho-graphic techniques.

Granted: 1981-05-12
Abstract: A B S T R A C T             A directional heat loss anemometer transducer for sens-ing both the speed and direction of motion of a fluid, liquid or gas in which the transducer is immersed.  The transducer is constructed of fine long cylindrical resistive conductors which are axially dis-posed about a supporting body wherein at least two conductors serve as a direction sensing pair which can also be used to determine im-pinging fluid speed.  For flow in opposite directions across the trans-ducer a third conductor can be used to independently sense speed when it is mounted so as to function as a freely supported fine cylin-der.  The direction sensing conductors are joined to the supporting body by an adhesive connecting means thereby preventing independent flow between the individual conductors of the conductor pair.  The electrical conductors can be metallic or resistive films which are deposited on a cylindrical supporting body, or they may be individ-ual wires of circular cross-section.  Each conductor which is act-ively used is made of a material which exhibits a change in its electrical resistance as a function of temperature.  Electrical con-nections are provided at each end of each conductor to permit each conductor to be separately excited by an electrical current.  Typi-cally, the transducer is operated in air so as to provide a non-moving parts means for measuring a particular component of wind speed, and a pair of othogonally mounted similar transducers can be used to determine sine and cosine components of wind speed.

Abstract: Abstract The present invention relates to the field of roof coverings, specifically laminated roof shingles formed of mineral granule covered, asphalt saturated felt material.  The disclosed shingle when combined with other shingles on a roof deck simulates a tile covered roof. This simulation is accomplished by making a generally rectangular laminated shingle having a headlap portion and an exposed butt portion made up of a regular uniform series of substantially identically shaped tabs with spaces therebetween defining exposed portions of an underlay member attached to the lower surface of the tabs.  The lower edges of these tabs and spaces define a butt edge having a generally continuously curving sinuous contour.  The tabs have generally straight sides which taper from this butt edge to the lower edge of the headlap portion.  A plurality of such shingles are placed on a roof deck such that the tabs are aligned vertically up the roof deck and the spaces between these tabs are also vertically aligned.  This simulation is emphasized by random color shading provided by the mineral granule covering.  The disclosed shingle is used to cover roof decks where aesthetic decisions dictate the desirability of having a tile covered roof.
