  • Patent number: RE30521
    Abstract: .[.Prior art high temperature electric furnaces of the type using two or more, usually three, primary electrodes positioned around an electrically conducting central outlet brought the electrodes in through a side or bottom wall of the furnace at points below the melt line causing many problems. The present invention provides a primary electrode arrangement for such melting furnaces wherein the primary electrodes do not pass through the wall or bottom of the furnace below the melt line, but instead enter the furnace over the top of the melt line and then protrude through the top surface of the melt. The primary electrodes of the present invention are provided with means for preventing wear and deterioration at the interface between the top surface of the melt and the unmelted batch and/or the oxidizing air atmosphere surrounding the top of the furnace. The improved furnace of the present invention does not require the use of a purging neutral or reducing atmosphere to protect the primary electrodes..]. .Iadd.

  • Patent number: RE30522
    Abstract: A rotor is provided for use in a wheel speed sensor assembly for sensing angular velocity of a wheel about a wheel support. The rotor is adapted to be mounted to a wheel for rotation therewith about an axis of rotation. The rotor includes a wall portion which extends in an axial direction coaxially about the axis of rotation and terminates in an annular edge portion. The rotor face has ripples or undulations formed therein which define an annular array of lands and recesses for providing wheel speed information to a sensor during wheel rotation. Also, the undulations provide a rotor face structure exhibiting a high degree of stiffness to resist deflection by forces applied to the rotor face. The wall portion also serves as an oil slinger to route oil or grease derived from a wheel hub or the like away from proximately located brake shoes. The rotor may be mounted to a wheel, such as to the brake drum mounting flange, by means of an annular flange which extends radially outward from the wall portion.

Medial and lateral pad members are positioned on the strap to engage the knee, extending rearwardly over medial and lateral sides thereof from the patella cover member. The posterior surface of the knee is covered by a flexure pad member. The several independent members allow flexion and extension of the leg while providing both support and protective padding for the knee joint.

  • Patent number: 4250582
    Abstract: By the method of the invention, textiles are disposed in a treatment chamber and compressed. While compressed, the fluid agent is uniformly dispersed under pressure in portions of the interior of the body of the compressed yarn and in a proportion just sufficient to effect the desired treatment. The apparatus and method of the invention are more efficient than prior art methods and apparatus, reduce water requirements and reduce the potentially undesirable impact of a textile treating process on the environment.

  • Patent number: 4250584
    Abstract: A collapsable swim fin includes a frame, a nonrigid blade or propulsion web, and tension members pivotally connected to the frame. The frame includes two slender, semirigid members extending forwardly from a swimmer's foot. The tensioning members include a pair of tension bars, each of which connect at one end to an opposite side of the frame members. The bars are pivotally interconnected at their other end, allowing movement of the bar members in a plane parallel with the blade. The blade or propulsion web is made of a collapsable material. Rotating the bars toward each other moves the frame members together and collapses the blade. Positioning the bars slightly past a colinear disposition to an overcenter orientation pushes the frame members apart, which tensions the blade material. The overcenter orientation causes the resilience of the propulsion webbing, in conjunction with a locking pin arrangement on the bars, to maintain the bars in a position to tension the propulsion webbing.

  • Patent number: 4250586
    Abstract: A paint applicator is disclosed for evenly spreading paint over a work surface, particularly an uneven work surface. A multi-cellular pad or sponge held by a pad holder is secured for vibratory movement to a manifold to which paint is delivered under pressure. Paint flows from the manifold and saturates the cellular pad. The arm of an electric vibrator or oscillator contacts the pad and imparts a vibratory or oscillatory motion to the pad. The vibrator or oscillator is supported in the housing secured to the manifold. The outer configuration of the housing may be shaped for gripping with the hand for paint application by an operator. Paint is delivered to the applicator from a pressurized container with the amount controlled by a flow control valve.
