  • Patent number: 3997958
    Abstract: An improved speedometer cable housing release and removal tool for disconnecting a speedometer cable housing from the speedometer head of an automobile or the like. The tool has an elongated curved body portion or handle with a linear portion at one end of the handle and extends to form a combination fulcrum-guide that is disposed generally in a plane perpendicular to the handle. The combination fulcrum-guide has a bending radius along a cable housing receiving groove permitting the tool to straddle the speedometer cable housing, thereby permitting the speedometer cable housing to serve as a finder for the tool. A depressing arm is connected to and proceeds from the combination fulcrum-guide generally parallel to an axis extensive through the linear portion of the handle. The depressing arm is of adequate length to reach a release trigger which is attached to the speedometer cable housing.

  • Patent number: 3979828
    Abstract: An improved prosthetic dentistry method and an improved dental prosthetic device wherein the prosthetic device includes an implant disposable in a fresh extraction site or a surgically produced extraction site as the patient conditions dictate, and a crown removably attachable to the implant. The implant has a configuration shaped to encourage hard tissue and bone ingrowth into and through portions of the implant for increasing the mechanical interlock between the implant and the existing alveolar bone. In practice, the implant is inserted into the socket opening formed at the extraction site and, after a healing period sufficient to assure the required mechanical interlock, the crown is secured to the implant, thereby providing a free-standing dental prosthetic device which does not require the adjacent teeth for support purposes. The crown would preferably be attached immediately in those instances involving the replacement of anterior teeth.

  • Patent number: 3969043
    Abstract: A submersible pump having a volume chamber with a volute wall integrally formed with and extending internally to a hermetically sealed housing. A fixed bearing is pressed in the interior wall of the volume chamber and is so established to determine the axial alignment of a drive shaft passing therethrough. The drive shaft is also supported by a self-aligning bearing disposed within the housing. An impeller, disposed within the volume chamber, is connected to the drive shaft. A drive motor enclosed in the housing rotates the drive shaft and the impeller, the motor being surrounded by a coolant fluid therein. Inlet and outlet ports are provided to complete the pump. As the impeller is rotated to pump a process fluid, the coolant fluid in the housing serves to lubricate the bearings and to effect heat transfer from the motor and bearings through the walls of the volume chamber to the process fluid.

  • Patent number: 3958063
    Abstract: A particle having superior bonding properties comprising crystalline portions connected together by a bonding material. The bonding material is relieved at the surface of the particle to provide capillaries extending into the particle between adjacent crystals. This results in the fusing material having a terminal surface recessed from the surface of the particle. The particle, when added to an elastomeric material, achieves superior mechanical, chemical and vacumatic bond strength as the elastomeric material is anchored to the particles by occupation of the capillaries, achieving increased bonding area.

  • Patent number: 3955661
    Abstract: An improved apparatus for opening and closing door members and the like such as elevator doors and garage doors, for example, wherein the driver rotatingly drives a driver shaft coupled to a driven shaft via a ball drive assembly, the ball drive assembly not only coupling the driver and the driven shafts so the driven shaft is rotated at a reduced rate of speed, but also cooperating to provide a portion of a torque control for sensing obstructions in the door member path of travel and automatically stopping or reversing the opening or the closing of the door member. The ball drive assembly has a relatively low moment of inertia, which facilitates faster stopping of the door member travel, and the internal friction of the ball drive assembly is greater than a pulley-belt type of coupling, for example, thereby increasing the amount of force required to move the door member from a stopped position.

  • Patent number: 3955399
    Abstract: The present invention relates to an improved uni-directional meter prover apparatus which includes a prover barrel having first and second ends, a piston disposed within the barrel which is propelled through the barrel by the flow of liquid therethrough, means for detecting the passage of the piston and comparing the volume of liquid displaced thereby with the volume of liquid measured by a meter being proved and means for transferring the piston from the second end of the prover barrel to the first end thereof. By the present invention, the first end of the prover barrel is positioned below the second end thereof and a piston transfer conduit is connected between the first and second ends of the prover barrel. First and second valve means are disposed within the transfer conduit for preventing liquid communication between the first and second ends of the prover barrel and for selectively retaining the piston therein.
