Abstract: A method for controlling car body roll in high capacity railraod freight cars, in accordance with which a hydro-pneumatic roll control unit is incorporated in the car truck spring groups that support the respective truck bolsters. The roll control unit comprises a base housing defining a lower or outer cylinder having an upstanding piston rod structure equipped with a piston head that reciprocably mounts a tubular ram having a ram head that operates in the outer cylinder and defines an upper or inner cylinder in which the base housing piston head operates. An annular rolling seal is received in circumambient relation about and connected to both cylinders invaginating leak free relation thereto, which defines an annular reservoir about said cylinders with which both cylinders have communication.

Abstract: A snap-on slide bearing for application to U-section formed sheet metal type guide lugs of unit brake beams for mounting the unit brake beams equipped with such guide lugs in the railroad car truck side frame unit brake beam guide brackets, preferably in place of the conventional spring steel wear plate now generally in use, comprising a one piece U-shaped clip member formed from spring steel and defining spaced apart superposed congruently related parallel arms integrally joined at like ends by abridging web, with the arms at their other ends being angled toward each other to define for each such arm a locating stop spaced from the clip member web approximately the length of the the guide lugs, and with the clip member arms each having affixed to the outer surfacing of same a strip that is preferably formed from a polymeric material, such as UHMW polyethylene, which strip is rectilinear and planar in outline, which strips are shaped and proportioned for substantially complemental but slidable seating in the

Abstract: A three-part telescoping uncoupling lever assembly is disclosed for railroad cars which are equipped with standard draft gear cushioning. The assembly includes a plastic sleeve formed from ultrahigh molecular weight polyethylene (U.H.M.W.) and a pair of unitary extension bars in sliding engagement within the sleeve. One end of each extension bar is bent to form a lock lifter hook or a handle for performing the uncoupling function. Each extension bar includes a shaft and an integral bent retainer, the bent retainers being positioned within the sleeve. The retainers are maintained in parallel sliding arrangement within juxtaposed channels extruded in the U.H.M.W. polyethylene sleeve. The hook and the handle are located on opposite ends of the assembly, the total length of which can be varied automatically between maximum and minimum lengths, dependent upon the corresponding distance between the coupler and sill bracket as that distance changes due to coupler impact and side swing.

Abstract: The invention comprises a blood lancet device for puncturing the fleshy part on the inner side of a finger tip, or an ear lobe, in order to draw blood for a hemoglobin test, or other type of blood test and which is completely sanitary to avoid any possibility of contamination of the blood drawn for testing. The device includes a finger grip element to be held by a user, with a surface adapted to be engaged with the fleshy finger tip pad, or ear lobe, and a hinged striker element pivotally mounted on the device and spring actuated to drive a sharp puncturing element secured on the striker, into such pad, with a thumb piece on the striker for drawing it back to a cocked position and having a twist-off or tear away protective element for maintaining the sanitary condition of the puncturing element until it is to be used.

Abstract: An agricultural row marker assembly is provided which includes a three-piece articulated arm and which is hydraulically actuated. The assembly has a base which is connectable to an agricultural tool bar. A second arm is pivotally mounted to the first arm and a telescopingly extendable third arm is pivotally connected to the second arm. A marker disc is located at the distal end of the third arm. The arm is hydraulically actuated with the hydraulic cylinder acting on the first arm through a link member. A second link runs from the base to the second arm and a cable runs between the second link and the third arm so that extension of the hydraulic cylinders extendable rod urges all three arms in the substantially linear alignment.

Abstract: An assembly for modular-type furniture is disclosed, including a vertical support post of rectangular cross-section, a panel and a horizontal structural member. At least one corner of the post has a pair of narrowly spaced-apart vertically extending flanges defining a slot for the end edge of the panel such that the panel and one contiguous surface of the post are in a nearly common plane. The panel is thinner than the width of the post and thinner than the structural member.

This basic casing member may take a number of specific forms for specific applications. For doorways, the sides or jambs and head of the doorway may be framed with two such members for each end of the doorway, and two similar casing members may be employed for the doorway head.

Abstract: An automatic power reduction circuit having a single silicon controlled rectifier in one leg of a bridge rectifier which is gated off when a capacitor reaches a predetermined voltage level so as to switch automatically the bridge output from a full-wave rectifier to a half-wave rectifier. An auxiliary silicon controlled rectifier is also provided to facilitate the quick discharge of the capacitor so as to reset the circuit to its initial state, thereby allowing fast, repeated operations and preventing malfunctioning upon a loss of power.
