Abstract: Exemplary power systems for dynamically controlling a dispenser drive motor for dispensing soap, sanitizing or lotion. An exemplary soap, sanitizing or lotion dispenser includes a housing, a receptacle for receiving a container for holding a soap, sanitizing or lotion, a container of soap, sanitizing or lotion and a pump secured to the container. The exemplary soap, sanitizing or lotion dispenser includes a power source, a motor and an actuator that couples the motor to the pump. In addition, the exemplary soap, sanitizing or lotion dispenser includes pulse width modulation circuitry in circuit communication with the power source and the motor. Movement of the actuator one actuation cycle dispenses a dose of soap, sanitizing or lotion. The pulse width modulation circuitry provides a plurality of voltage pulses to the motor to move the actuator one actuation cycle.

Abstract: An improved stiffener reinforced assembly and method. There is a skin member and a stiffener member including a web portion, a flange portion, and a radius region interconnecting the web portion and the flange portion. The flange portion resides on the skin member. A plurality of reinforcing pins are disposed through the radius region of the stiffener member and into the skin member to secure the stiffener member to the skin member.

Abstract: An ultrasonic fastening system wherein an ultrasonic transducer is used to insert a plurality of fasteners supported by a compressible member into two components to be joined or a single composite part to be reinforced.

Abstract: Method for storing foam covers and for installing foam covers on clothes hangers, and apparatus to perform the method. A supply of foam covers are loaded on an insert spindle. The insert spindle is suspendable, and is formed to receive therein the hook of a clothes hanger. The insert spindle may further define a spreader to assist in spreading the slot of a foam cover over the hook of the clothes hanger. After suspending the insert spindle having at least one foam cover installed thereon, the operator inserts the hook of a clothes hanger into a hanger pocket formed at a lower end of the insert spindle. To install the cover onto the hanger the operator, by grasping the foam cover at either end thereof with the thumb and forefinger of each hand, and pulling the cover with a downward and outward motion, will cause the foam cover to slide down the insert spindle over the hook and onto the clothes hanger.

Abstract: An electro-pneumatic circuit is provided for cycling a holding magnet valve located in the brake cylinder exhaust pipe of a rail car brake system. As brake pipe pressure rises to signal full or partial release of the brakes, the holding valve is alternately opened and closed to provide a graduated release. The circuit is particularly adapted for rail cars having an electrical train line for controlling the holding valve to permit such cars to be used with other types of cars having a purely pneumatic control for graduated brake release.
