Abstract: A showerhead is connected to a length of flexible weighed hose which is run through the shower wall. The showerhead may be pulled away from the wall and the hose extended out from the wall accordingly. When showerhead is replaced in a bracket against the wall the hose retracts back inside the wall.
Abstract: A magnetic filter removes magnetic particles from fluid communicated through the filter. The filter includes elongated, circumferentially spaced magnetic elements which capture magnetic particles entrained in the turbulent passing fluid. The magnetic elements must be cleaned periodically to remove the particles from the elements by moving a scraper plate from one end of the housing to the other. At the end of travel of the scraper plate, the particles are scraped upon non-magnetic end portions (which may contain residual magnetism) of the magnetic elements, from which they are flushed by fluid communicated through the inlet port out through other ports provided on the housing.
Abstract: A light fixture with a light is electrically controlled by a magnetic switch positioned about the juncture between a door or movable cap and the frame such that the light may be switched on when the door or cap is away from the frame and the light may be switched off when the door or cap is closed next to the frame.
Abstract: An improved method and apparatus for heat sealing bags having a mandrel with protruding needles for holding the bag material when the material is wrapped around the mandrel. The mandrel has a ridge for allowing easy penetration of an upwardly angled hot blade between the two overlapping ends of the bag. An apparatus composed of three hot blades of which the two outside blades enter the bottom of the bag and expand outward contacting an inner perimeter of the bag when the middle blade moves forward. The blades then retract and the bag is then fused together by pressure bars and cut by heat trimmers.
Abstract: Shot peening coverage is confirmed by mounting a test strip having surface irregularities of graduated depth on a surface of a component undergoing peening for which peening coverage is to be confirmed. The component, with the test strip attached thereto, is exposed to the shot stream under production conditions. The strip, which is selected according to a procedure described herein such that some, but not all, of the surface irregularities are removed when proper peening coverage is attained, is then removed and examined.
Abstract: An orthopedic device of a therapeutic nature which includes an air bladder and an overlying gel bladder. The air and gel bladders are joined and are secured within a retainer which is adapted to be placed about a body part of a patient with the air or gel bladder being positioned next to the body part.

Abstract: A slide-out room for recreational vehicles, sleeper cabs of trucks, and similar mobile living quarters is supported for movement through an aperture in the side wall of the mobile living quarters by a set of four linkages, two of which are mounted between each side of the slide-out room in the corresponding side of the aperture of the side wall of the unit. When the slide-out room is fully retracted within the mobile living quarters, one of the linkages on each side of the slide-out room is fully extended and the other is fully collapsed. As the slide-out room is moved toward the fully-extended position, the other linkage gradually expands and the one linkage collapses, so in the fully extended, as well as the fully retracted position, the slide-out room is supported and aligned for movement through the aperture in the vehicle slide-out room, and the slide-out room is continuously supported as it travels between the extended and retracted positions.
Abstract: A wheel assembly which includes a wheel having a central bore and an attached hubcap. An axle is fitted into the central bore of the wheel assembly and interlocks with the hubcap, serving to secure the wheel assembly to the axle while permitting movement of the wheel relative to the axle.

Abstract: An adjustable gauge having special attention to measuring the dimensions of a fillet weld. The gauge includes a first plate that is rectangular in shape and terminates in an edge which transverses one corner, and a second plate that is circular in shape. The front face of the first plate has a recess therein sized to accommodate the second plate, wherein the plates are rotatably mounted about an axis of rotation and juxtaposed to one another. The gauge also indicates a linear member slidably mounted along the same axis of rotation as the first and second plates upon the second plate. The linear member is extendible in relation to the second plate so as to measure the dimension of the weld.
Abstract: A holder for mounting a test strip for measuring the intensity of shot peening in internal cavities includes a receptacle receiving any of multiple inserts configured to form a segment of an internal cavity of a component to be peened. The test strip defines the remainder of the cavity. The shot stream to be measured is introduce into the cavity, after which the test strip is removed and measured in the conventional manner. Accordingly, the intensity of peening in internal cavities may be measured with relative accuracy. By providing multiple inserts, intensity of peening in cavities of varying sizes may be measured by simply changing the insert.
Abstract: A hand brake for a rail car which is adapted to be connected to the actuator which forms a part of the brake system of the car. A chain wheel about which the actuator chain is wrapped is rotated through a hydraulic cylinder causing the chain to actuate the brake system.
Abstract: An instrument bracket, primarily for holding medical instrumentation, having a clip part which is mountable to a plate and a holder part. The plate may form a part of a sterilization tray or similar container. The clip part is of an inverted U-shaped configuration having spaced upwardly projecting legs. The clip part fits about the holder part which is flexible and shape retaining and which includes a recess to accommodate the instrumentation. The clip part compresses and retains the holder part and is secured to the plate.
Abstract: A carry-on case having a base and a connected lid. A handle is pivotally carried by the lid and is shiftable between a lowered position overlying the lid and a raised position extending upwardly from the lid. The handle is extendable between a collapsed position in which the grip of the handle is next to the lid and an extended position in which the grip is substantially spaced from the lid. Wheels are carried by the base. The handle includes releasable lock pins which extend upwardly and downwardly from a cross brace forming a part of the handle and which serve to secure the handle in either of its extended or collapsed positions. When the handle is in its collapsed position, the upwardly extending lock pins are enclosed by the handle leaving the lower extending lock pins available to release the handle for its extendable movement.
