Abstract: A lubricated bearing has a rotatable structure which includes a housing with an opening at one end, a bearing cup and a retaining member. The retaining member grips the exterior of the bearing cup and the interior of the housing to secure the bearing cup within the housing with its mouth towards the opening and with lubricant spaces between the housing and bearing cup both above and below its rim. A stationary member has a spherical part which fits within the bearing cup to provide relatively rotatable bearing surfaces and a shaft which extends out of the housing through the opening.

Abstract: An apparatus for transferring tubulars between the floor of a drilling rig and a pipe rack including an elongated main support frame adapted to be positioned in proximity to the pipe rack, a lift trough positioned longitudinally of the support frame and having one end pivotally coupled to the main support frame, whereby the lift trough can be pivoted upwardly to an inclined position, a power member connected to the lift trough for pivoting the lift trough upwardly to an inclined position relative to the main support frame and toward the drilling rig and downwardly to a generally horizontal position, and a carriage including a movable holding tray operatively connected to the lift trough for moving tubulars positioned in the lift trough along its length. An adjustable fixed trough supported on a drilling rig floor, sloping towards the lift trough and connectable with it when it is in the inclined position for transferring tubulars to the rig floor.

Abstract: A workpiece gripping mechanism for an industrial robot is described. A support member having a first jaw member mounted on it for pivotal movement about a first axis is provided. The support assembly and the first jaw assembly define a first rotary fluid-actuated motor operable to pivotally displace a jaw member in the first jaw assembly relative to the support member about the first axis. A second jaw assembly is also mounted on the support member for pivotal movement about the first axis. The support member and the second jaw assembly define a second rotary fluid-actuated motor operable to pivotally displace a jaw member in the second jaw assembly relative to the support member about the first axis whereby the first and second fluid-actuated motors may be operated independently to pivotally displace the jaw members relative to each other for gripping and releasing a workpiece and to displace the jaw members relative to the support member.

Abstract: An apparatus for producing particulate material from compact masses of materials such as that used for insulation and then pneumatically dispensing the material in a uniform flow and with a preselected and consistent density. The apparatus includes a hopper for receiving the compact masses, an outlet positioned in the bottom of the hopper and a shredding zone located within the upper portion of the hopper for shredding large compact masses into smaller masses or nodules. An auger is positioned below the shredding zone and above the outlet for moving the material along the hopper. Below the auger is a tearing and separating zone that receives the material from the outlet and operates to tear and separate any of the nodules of the material into particulate material. The particulate material is then received and dispensed by a pneumatic transport means. The transport means includes a rotating air lock having an inlet at one end and an end plate at the other or exhaust end of the air lock.

Abstract: A diaper incorporating quick release means in the form of strips of Velcro (trademark) tape. A body encircling edge of the diaper is provided with strips of the tape on both sides while the opposite edge is provided with complemental strips fixed directly to the diaper and on a flexible element. In use of the invention the strips of tape permit rapid location of the diaper on an infant's body and the diaper may thereafter be adjusted. The flexible element serves to reinforce the attachment.

Abstract: A method of making a connecting rod for an internal combustion engine having a one-piece crankshaft construction generally consisting of positioning a first crankpin bushing segment having a connecting rod shank consisting of a reinforced resinous material mounted thereon, on a crankpin of the crankshaft, positioning a second crankpin bushing segment on the crankpin, and applying a reinforcing material and a resinous material about a periphery of the connecting rod shank and the second crankpin bushing segment to form an integral unit consisting of the crankpin bushing segments embedded in the connecting rod shank, attached to the crankpin.

Abstract: As new semi-synthetic antibiotic derivative are provided N-methanesulfonic acid derivatives of istamycin A or B which are lower toxic than the parent antibiotic and retain usefully high antibacterial activity. They are produced by N-sulfomethylation in such way that istamycin A or B is reacted with an aldehyde such as paraformaldehyde and sulfurous acid or sulfite reagent.

Abstract: A low profile, flexible tying device for holding or retaining shoelaces in place. The device includes a base portion having a slot and a tongue portion for insertion into the slot. A portion of the tongue portion is serrated to engage surfaces defining the slot to lock the device about a shoe lace knot. Dimples are provided on the tongue portion for gripping the shoelace material.

Abstract: A plantain impregnated with fruit juice, particularly orange juice, having a unique taste and texture. Plantains are selected with ripeness such that the sugar content is derived from at least 70% conversion of the starch to sugar, peeling the plantains and then apply a high vacuum to the plantains. The plantains are then immersed in a solution of fruit juice. When the vacuum is released, the plantains are held immersed in the fruit juice for a sufficient dwell time. The impregnated fruit is then removed and it is frozen. The fruit prior to impregnation is desirably preserved from fungus attack by ripening the plantains in a low humidity of about a maximum of 40% relative humidity and/or contacting the plantains with a fungicide, such as that containing chlorine.

Abstract: An ethylene gas generating liquid composition for catalytic conversion to ethylene. Ethanol is the primary ingredient of the liquid composition but there is also present 1.0% to 15% methanol, 0.1% to 10% of an ester such as amyl acetate and 0.1% to 15% of an aliphatic alcohol such as isopropanol. This liquid composition has been found to maintain a high conversion efficiency for the catalyst and minimizes the production of by-products.

Abstract: A fire fighting composition and method for spraying a low volume liquid stream without foam onto a fire that conserves the volume of fluid used and yet more quickly snuffs out the fire. The fire fighting composition is formed from a concentrate comprising one or more nonionic surfactants having a combined cloud point of 68.degree. F.-212.degree. F. and sufficient water to form a concentrate solution of not greater than 30% by weight of the surfactant. The ultimate fire fighting composition is formed from the concentrate and passed through a conventional pump. A fire fighting solution is formed having not greater than 0.2% by volume of the surfactant that does not cause undesirable foaming or cavitation of the pump due to the low concentration of the surfactant. The fire fighting solution in this form is sprayed onto fires to form an effective means for combatting fires while achieving high versatility for conventional fire fighting pumping apparatus.

Abstract: A tree shearing apparatus including a main frame mountable on support arms of a machine, a pair of pivot pins mounted on the main frame, a blade support arm mounted on each of the pivot pins for pivotal movement about the axis of that pivot pin, a cutting blade having a leading cutting edge mounted on each of the blade support arms, an element mounted on the main frame that pivots the blade support arm thereby moving the leading cutting edges toward and away from each other, causing the leading cutting edges to sever a tree trunk or the like positioned between them, and an element mounted on the main frame and operatively connected to at least one of the pivot pins that adjusts the attitude of the pivot pin and correspondingly adjusts the inter-relationship of the positions of the leading cutting edges of the blades.
