  • Publication number: 20190274487
    Abstract: An dispenser includes a housing, a container disposed in the housing for holding a liquid, a nozzle, and a pump. The pump is disposed between the container and the nozzle. The pump includes a pump inlet, a pump outlet, a pump chamber, a first check valve, and a second check valve. The pump inlet is in fluid communication with the container and the pump chamber, and the pump outlet is in fluid communication with the pump chamber and the nozzle. The pump chamber is movable between an expanded position and a compressed position. The first check valve is disposed between the container and the pump, and the first check valve has a first cracking pressure. The second check valve is disposed between the first check valve and the pump, and the second check valve has a second cracking pressure. The first cracking pressure of the first check valve is greater than the second cracking pressure of the second check valve.

  • Publication number: 20190133384
    Abstract: Exemplary soap, sanitizer and lotion dispensers are disclosed herein. An exemplary dispenser includes a housing; a receptacle for receiving a container; a container of fluid comprising soap, sanitizer or lotion; a pump in fluid communication with the container; a power source; a pump coupled to a motor and pulse width modulation circuitry in circuit communication with the power source and the motor. The pulse width modulation circuitry is initially set to cause a selected dose of fluid to be dispensed at a base speed. A sensor for detecting a parameter indicative of an actual speed of a dispense of the fluid is also included. When the actual speed of the dispense of fluid is less than the base speed or greater than the base speed, the pulse width modulation circuitry adjusts the pulse width to cause the speed of a following dispense of fluid to be closer to the base speed.

  • Patent number: 8533921
    Abstract: An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty. The tool includes a first member operably associated with the first component and defines a first member longitudinal axis thereof. A second member is operably associated with the second component and defines a second member longitudinal axis thereof. A washer system is coupled to the second member. A drive mechanism is coupled to washer system, such that as the drive mechanism is activated, the washer system rotates about the second member longitudinal axis and expands along the second member longitudinal axis, wherein such movement further causes the second member to move relative to the first member along the second member longitudinal axis.

  • Publication number: 20110039014
    Abstract: An implantable prosthetic bearing is constructed of a composite material having a first layer and second layer. The first layer has an articulating surface defined therein, whereas the second layer has a engaging surface defined therein for engaging either another prosthetic component or the bone itself. The first layer of the implantable prosthetic bearing is constructed of crosslinked polymer such as Ultra-High Molecular Weight Polyethylene, whereas the second layer of the implantable prosthetic bearing is constructed of polymer such as Ultra-High Molecular Weight Polyethylene that is either non-crosslinked or crosslinked to a lesser degree than the first layer. In such a manner, the first layer possesses mechanical properties which are advantageous in regard to the articulating surface (e.g., enhanced wear and oxidation resistance), whereas the second layer possesses mechanical properties which are advantageous in regard to the engaging surface (e.g., high ductility, toughness, and creep resistance).

  • Patent number: 7186364
    Abstract: An implantable prosthetic bearing is constructed of a composite material having a first layer and second layer. The first layer has an articulating surface defined therein, whereas the second layer has a engaging surface defined therein for engaging either another prosthetic component or the bone itself. The first layer of the implantable prosthetic bearing is constructed of a polymer such as polyethylene or UHMWPE, whereas the second layer is constructed of a copolymer of ethylene and an acrylate. The ethylene portion of the copolymer provides for adhesion to the polymer of the first layer, whereas the acrylate portion of the copolymer provides for adhesion to commonly utilized bone cements. A method of making a prosthetic bearing is also disclosed.

  • Patent number: 6818172
    Abstract: A process for forming an oriented orthopaedic implant prosthesis bearing, net-shape bearing, or near net-shape bearing includes the step of placing an irradiated UHMWPE preform or puck of a volume sufficient to accommodate the bearing in a compression mold and compression molding the irradiated preform. The molding is accomplished by applying heat and pressure to form the preform into a desired shape. The compression molding induces biaxial orientation in the formed bearing.

  • Patent number: 6692679
    Abstract: A method is provided for forming a plastic prosthesis bearing, net-shape bearing, near net-shape bearing or plastic stock from which such a bearing can be formed. The method includes the steps of providing plastic resin in powdered form, subjecting the powdered resin to irradiation to cross-link the resin, and molding the irradiated powder. The irradiated powder is molded by applying heat and pressure to form the powder into a desired solid plastic shape, the heating being sufficient to melt the powder.
