  • Patent number: 6527251
    Abstract: A scissor jack assembly with double-lead Acme threaded screw. Through use of urethane or similar material as a braking means, the jack assembly is operable with a self locking action over a wider range of loads and especially at lower loads where an Acme loading phenomenon that results in said self locking action has previously been unattainable. Faster and smoother jack operation is made possible by employing a thrust bearing, including a plurality of roller or ball bearings, with the jack assembly.

  • Patent number: 6362241
    Abstract: The invention relates to processes and apparatus for the production of a virgin polymer substitute from cured scrap rubber, such as automobile tires, which does not involve the use of solvents or other chemicals and which substantially maintains the physical properties of the virgin material in the substitute. The process and apparatus may perform an initial analysis of the scrap material to be treated and determination of the process parameters for that particular material. Actual treatment of the material comprises grinding of the scrap rubber and preconditioning the ground material by subjecting it to warm dry air prior to subsequent treatment in a high temperature and pressure environment. The high temperature and pressure environment is created by means of a pressure vessel into which the preconditioned material is introduced, thereafter exposing the material to a variable high pressure and temperature environment which is controlled to optimize devulcanization of the material.

  • Patent number: 6336537
    Abstract: An integrated wheel end assembly for a vehicle including a wheel hub, a stub shaft, a torque flange and a bi-directional overrunning clutch member is configured such that the clutch automatically acts as a hub lock. The wheel hub is drivingly engaged to a drive flange mounted at an inboard end thereof. An outer circumference of the drive flange has a plurality of external teeth spaced evenly therearound. An outboard end of the stub shaft is rotatingly supported in the wheel hub and an inboard end thereof defines a housing for a CV joint. This CV housing and the drive flange are positioned axially adjacent to each other. The bi-directional overrunning clutch member comprises two clutch plates, one drivingly connected to the CV housing and the other drivingly connected to the drive flange. In a first configuration the clutch plates are disengaged such that the rotating CV housing causes only the corresponding clutch plate to rotate and no drive torque is transferred from the half shaft to the wheel hub.

  • Patent number: 6305246
    Abstract: A lubrication port is placed in the yoke of a pneumatic powered ratchet wrench or the head of a hand powered ratchet wrench. The lubrication port is placed so that it intersects with the teeth formed on the circumference of the bore formed in the yoke or the ratchet head which come in contact with the teeth formed on the outer ends of the pawl(s) of a ratchet mechanism. This allows for the application of lubricants, preferably grease, to the area of engagement between the teeth formed on the circumference of the bore of the yoke, ratchet head or ratchet mechanism and the teeth formed on the outer ends of the pawl(s) of a ratchet mechanism. Application of lubricants through the lubrication port of the present invention also allows for lubrication of the moving components of the ratchet assembly. Moreover, in a pneumatic powered ratchet wrench the lubrication port allows for application of lubricants to the drive bushing and crank of the wrench.

  • Patent number: 6302336
    Abstract: A watering container with a rotatable nozzle having a plurality of water delivery patterns. In particular, a rotatable nozzle having a plurality of water delivery patterns is rotationally attached to a water spout on a watering container. A user can turn the rotatable nozzle to select the desired water delivery pattern. In a preferred embodiment of the watering container, the user may select either a steady stream water pattern or a dispersed rosette water spray pattern. The watering container includes an internal fluid reservoir which can vary in volume based on the needs of the user. Water exits the internal fluid reservoir and flows through the water spout and then through the water delivery pattern selected by the user on the rotatable nozzle when the watering container is properly tilted. An integral elongated handle on the watering container enables the user to reduce stress on their hand and wrist during the tilting process.

  • Patent number: 6300394
    Abstract: A modified coal tar useful in roofing applications, containing coal tar, a nitrile butadiene rubber, and in some instances an effective amount of a plasticizer is prepared by heating the coal tar to a molten temperature, adding the rubber in powder form and agitating the material in a suitable high shear mixing apparatus until adequate phase inversion occurs between the polymer and the coal tar phase. After preparation, the material is cooled in containers until use, at which time it is heated to a flowable temperature and applied using a roofing mop or squeegee. Effective plasticizers include the alkyl esters of di-functional carboxylic acids, such as di-octyl adipate and di-octyl phthalate.

  • Patent number: 6293889
    Abstract: Limited slip motor vehicle differential assemblies having a suitable high-shear strength, non-hardening, material which selectively resists slip or differentiation between the axle shafts and the differential housing, between the differential side gears and the differential housing, and/or between the differential side gears and the differential pinion gears when slip or differentiation occurs between two motor vehicle wheels mounted on the same axle. Such an arrangement provides some level of torque to each motor vehicle wheel at all times. The amount of resistance to slip or differentiation between the two motor vehicle wheels can be adjusted as desired by selecting an appropriate high-shear strength, non-hardening, material to provide the desired level of resistance to slip or differentiation between the two motor vehicle wheels in the motor vehicle differential assembly.

  • Patent number: 6289106
    Abstract: The present invention consists of an improved distortion reduction cap and center pole speaker assembly and an improved method of coupling the cap to a speaker center pole. The cap includes an axial flare which is stretched over and pressed into a corresponding axial gripping surface to provide a permanent coupling of the cap to a speaker center pole that does not vibrate or come loose and that eliminates air gaps between the cap and the center pole. The method of coupling the cap to the speaker center pole consists of forming the caps through known die cut stamping and forming a slightly raised corresponding axial gripping surface on the center pole of a speaker pole yoke assembly. The cap is placed over the center pole and then forced into a molding applicator tool.
