Abstract: A seal is particularly suited for closing the ends of an antifriction bearing which is located on a journal where its inner races are captured between wear rings and backing elements having overhangs which are directed back toward the end of the bearings and, as such, encircle the wear rings. Indeed, a seal exists at each end of the bearing for isolating the annular space between the inner and outer races of the bearing. Each seal includes a case that is fitted into the end of the outer race and projects axially from that race as well as radially inwardly toward the wear ring. In addition, it has two elastomeric lips which are presented toward the wear ring, one being configured primarily to retain lubricant in the annular space between the two races of the bearing and the other to exclude contaminants from that space. The seal also has an elastomeric spray shield which is attached to the case and projects radially outwardly from it toward the overhang.

Abstract: A seal assembly for antifriction bearings in which a cone and a cup have raceways for roller bearings, a seal case carried by the cone and by the cup for supporting a seal element on each of the seal cases to provide a space therebetween for retention of a body of lubricant in position to create a barrier for blocking the ingress of contaminants from the exterior. One of the seals is positioned to be exposed to the outside to have a lip operative on one of the seal cases to preclude the ingress of contaminants, and the other one of the seals is exposed to the bearing interior to allow lubricant to pass into the cavity between the seals and also to assure the presence of lubricant to the interior of the bearing assembly.

Abstract: A traction drive unit for transmitting rotary motion about an axis of rotation has an inner sun roller, an outer ring and planet rollers arranged in two circular rows between the sun roller and outer ring. The sun roller takes the form of a double cone having outwardly presented raceways which taper downwardly toward each other and thrust ribs that project radially beyond the large ends of the raceways. The outer ring has two inwardly presented tapered raceways which taper downwardly toward the ends of the ring. The inner planet rollers are tapered rollers which are organized in two circular rows along the raceways of the sun member. The outer planet rollers have crowned peripheral surfaces which contact the tapered raceways of the outer ring and the tapered side surfaces of the inner planet rollers. They are captured axially by reason of the taper of the outer raceways and inner planet rollers. The outer rollers revolve in pairs about axles which are fitted to end disks.

Abstract: A low alcohol reduced calorie beer is produced by a mashing technique wherein a main mash at a temperature below the activity range for beta-amylase is added incrementally to a brewing liquid at a temperature above the deactivation temperature of beta-amylase and below the deactivation temperature of alpha-amylase at a rate such that the added main mash is substantially instantaneously raised to the temperature of the brewing liquid. This mashing technique limits the conversion of starches by beta-amylase and other enzymes without significant loss of alpha-amylase from overheating to produce a wort having a low real degree of fermentation of from about 40% to about 46%. The main mash has a temperature of about 95.degree. F. to 120.degree. F., and the brewing liquid has a temperature of about 169.degree. F. to 174.degree. F. and can be water or a cooker mash that has been boiled and cooled. Beer can be produced having less than 2% alcohol by weight and less than about 118 calories per 12 ounce serving.

Abstract: A rotary hammer grinding mill having the rotary hammer rotor exposed in a housing between a material inlet and a ground material outlet in which the grate assembly on the outlet side of the rotor is composed of a series of spaced cradle ribs curving around the outlet side of the rotor and supporting a series of spaced bars directed transversely to the cradle ribs. The cradle ribs and bar spacing defines a series of openings having short passages offering greatly reduced resistance to the flow of ground material so there is substantially established a down-draft operation of the mill without the need to connect up a suction fan to the mill outlet.

Abstract: A system for disposing of sludge by using the sludge as a primary source of fuel for its disposition by combustion thereof in which a mass of liquified sludge is processed to reduce the solids to a predetermined size for use as the fuel and concurrently separating a substantial portion of the contained liquid, delivering the processed solids and liquids to a combustor for converting the solids to ash and converting the liquids to vapor, introducing ambient air to the combustor to support combustion of the solids while employing a portion of the ambient air to the combustor for removing the vapor at a temperature below the temperature at which the solids are reduced to ash, utilizing a portion of the vapor removed from the combustor to initiate vaporization of the liquid in the mass of liquified sludge being processed initially, using a part of the removed vapor to enter into a heat exchange relationship with the ambient air prior to its being admitted to the combustor, and releasing excess vapor to the ambien

Abstract: A bearing assembly fits over the journal at the end of a shaft and is clamped between a fillet at one end of the journal and an end cap which extends across the opposite end of the journal. The bearing assembly includes a double row tapered roller bearing having a two indirectly mounted cones, a double cup around the cones, and tapered rollers arranged in two rows between the raceways of the cones and cup. The bearing assembly also includes seal rings located against the cones and seals fitted into the end of the cup and cooperating with the seal rings to establish barriers at the ends of the bearings. The outboard seal ring is clamped between the end cap and the outboard cone, whereas the inboard seal ring is clamped between the inboard cone and the backing ring. A slight clearance exists between the inboard seal ring and the journal to prevent fretting beneath that seal ring due to slight flexures in the journal.

Abstract: Dynamic rock stabilization apparatus in the form of an anchor fixture for use with a roof plate in which the fixture has an anchor rod formed with a surface configuration extending from a lead-in end to the opposite headed end for at least a part of the length of the rod, and a hollow body providing a wall of formable and compressible material having a length less than the depth of a bore hole in the rock structure into which it is to be placed between the rod and the surface of the bore hole, the body engaging the surface configuration of the rod to effect a locking engagement with the rod such that when assembled in a bore hole the body wall has a thickness sufficient to be compressed between the rod surface configuration which has a diameter less than the bore hole and the bore hole surface, and to apply dynamic forces through the rock as a result of the compressibility of the body.

Abstract: A control system for the hydraulic operating circuit associated with a vehicle lifting device in which the circuit is provided with pressure fluid control valves and flow sensors which are operative on the vehicle lowering cycle to establish substantial evenness of the lowering mechanism and protection against malfunction of an operating component to arrest the travel of the vehicle lifting device in its lowering cycle.

Abstract: A bearing assembly for supporting a shaft in a housing includes two single row tapered roller bearings mounted in axial alignment, yet in opposition. The first bearing is conventional, having the usual cup, cone and complement of tapered rollers. The second bearing has a conventional cone and complement of rollers which may be the same as their counterparts in the first bearing. However, the cup of the second bearing further has an integral axial extension which projects toward and abuts the back face of the cup for the first bearing. The two cones are separated by a spacer and are clamped between two radial abutments on the shaft, whereas the cup of the second bearing is clamped with respect to the housing such that it is incapable of shifting relative to the housing. This secures the entire bearing assembly in the housing.

Abstract: The apparatus herein comprises a kettle for calcining particulate material and a surrounding furnace having a porous wall to pass heat of combustion into the kettle at one side and to permit evacuation of the products of combustion from an opposite side, and a control system to cycle the combustion and the evacuation of products of combustion between the opposite sides so that the side being evacuated becomes a heat sink to return the heat so retained therein upon the combustion cycle whereby the furnace structure is kept to a desirable level of temperature while the material in the kettle is at a significant higher temperature.

Abstract: A material grinding mill of reversible character having hog-type hammers formed with chisel edges pivotally mounted on supporting discs, and further formed with landing areas positioned to contact the supporting discs so that the chisel edges are prevented from impacting upon or nicking the discs. The pivoting of the hammers allows them to rebound when encountering a body of hardened material so the hammer reverses direction, hence the landing area impacts on the discs and the discs are protected against being nicked by the chisel edges of the hammers.

The leg segments and the clamp member are configured to allow the hinge members to rotatably traverse a greater than 180 degree arcuate path of travel relative to each other.

Abstract: A thrust bearing assembly for a pinless hinge structure having two longitudinally extending hinge members which are rotatory joined to each other and a longitudinally extending clamp member. The thrust bearing assembly includes a thrust bearing member having multiple bearing support surfaces which are longitudinally joined to each other. Each bearing surface is preferably non metallic and extends laterally across adjacent longitudinal edges of the hinge members to inhibit relative longitudinal movement between the hinge members.

Abstract: A pinless hinge structure having two hinge members which are rotatably joined for movement between open and closed positions. The hinge members have longitudinally extending gear segments which intermesh with an interior surface on a clamp member such that each hinge member moves about an axis of rotation which shifts as a function of the position of the hinge members. A thrust bearing assembly inhibits relative longitudinal movement between the hinge members and the clamp member.

Abstract: A container for dispensing thin line, such as tippet material used for fishing, includes a housing having a flat end wall and a cylindrical peripheral wall which together define a cavity for holding several spools of the line. The lines pass from their respective spools through a slit in the peripheral wall. The slit has elastomeric liners along its edges, and these liners serve to grip the line, so that its ends are presented for gripping beyond the container. The housing also has a spindle which projects from the end wall of the housing through the spools, beyond which it has a screw thread. An end plate extends across the cavity where it opens out of the housing, this plate being attached to the housing at the screw threads on the spindle so that it can be turned down to clamp the spools between it and the end wall of this housing. This controls the resistance with which the spools will rotate when dispensing line.
