Abstract: A rail anchor assembly is provided with particularly-configured shoulder fittings welded to a base plate component in a manner which eliminates the necessity of weld grinding in order to assure non-interference between the shoulder fitting rail abutment end weld and a cooperating rail positioned upon the base plate component in proximity to the weld. The shoulder fitting rail abutment end includes an undercut which extends with increasing depth from the shoulder fitting rail abutment end vertical rail abutment face toward the rail retainer spring clip opening portion of the shoulder fitting to thereby form one side of a weld bevel groove accessible from within the shoulder fitting spring clip opening portion.

Abstract: An externally threaded fitting for use in coupling a fluid-conducting tube to a fluid-processing system threaded entrance opening is provided with a tapered-bottom groove immediately above and adjacent the fitting external thread, and with a doubly-tapered, polytetrafluoroethylene material seal element contained in the tapered-bottom groove. Upon proper installation in the system threaded entrance opening, the doubly-tapered seal element is fully isostatically compressed with total concealment of fitting external threads.

Abstract: An interlock panel has a plurality of laterally spaced teeth which define tooth slots and pairs of spaced lugs which define interlock slots. Each tooth slot is aligned with an interlock slot to receive one of the top and bottom area of a panel to provide a double interlock when a pair of panels are joined.

Abstract: A manually-operable railroad switch stand for causing movement of railroad switch points between two extreme operating positions is provided with a crank assembly that is connected to the switch stand input shaft for joint rotation and that has a pair of parallel and substantially laterally spaced-apart handle pull-push segments which are each of sufficient length to alternatively accommodate an operator's hand or an operator's foot and which each may be selectively hand-grasped or foot-engaged by the switch stand operator without having to significantly bend his/her spinal column at the waist when manually causing movement of the switch points between the switch extreme operating positions thus avoiding possible costly operator spinal injury.

Abstract: A liquid-dispensing container for repeatedly dispensing a predetermined volume of liquid when repeatedly inverted is provided with a container housing element, and with a collapsible partition element attached in a gas-and liquid-tight manner to the bottom of the housing element to thus form a variable bladder volume which is continuously vented to the atmosphere and which defines the predetermined volume of liquid to be dispensed.

Abstract: A novel brake friction pad assembly is provided with a backing plate element, and with one or more integrally joined different friction-generating pad, noise-damping pad, and backing pad elements carried by the backing plate element, such friction-generating pad, noise-damping pad, and backing pad elements being molded using specified particulate mixture molding compositions and preferred molding method steps.

Abstract: A noise abating brake shoe assembly having a metal brake shoe and a friction material brake block with an elastomeric sound damping material added as a constituent to the brake block or interposed between the brake block and the brake shoe.

Abstract: A method for moving with at least three degrees of freedom, particularly in theatre area on or below a stage, a complex three-dimensional structure, which is borne by several lifting machines or the like to be driven independently, is described. Three virtual parallel reference axes are installed in the space on which, as a function of one positioning signal in each case per point of application up or down movements are made. A virtual surface is drawn by these points of application. Several independent lifting machines or the like are installed above or below this surface. A weighting is determined for each lifting machine as a function of their position compared to each reference axis, which weighting is a measure of the amount by which the running of the relevant machine is influenced by the movement of the points of application on the reference axes. The movement and speed of movement of the points of application on the reference axes are predefined as positioning signals.

Abstract: A closure valve assembly for the discharge outlet line of a garbage disposal has a resilient deformable housing which defines a fluid passage and a rigid valve element pivotal in said housing and having an outer circumferential surface with a greater diameter than that of the inside surface of said housing.

Abstract: A therapeutic pillow assembly set is provided with interchangeable resilient neck-support components of different sizes, interchangeable resilient side-support components of different sizes, interchangeable resilient shoulder-support components of different sizes, and interchangeable resilient height-adjustment components of different sizes all of which are each selectively and detachably secured to a resilient base component by detachable-type fastener means.

Abstract: A farm tractor field stone collection implement is provided with a forward dragbox section having open forward and aft ends, a perforated bottom, multiple spaced-apart teeth projected forwardly and downwardly from the section leading edge, and hitch points for coupling to a farm tractor implement hitch accessory, with an aft dragbox section having a forward open end aligned with the forward dragbox section open aft end, a perforated bottom, and an aft end from which collected field stone may be dumped, with a vibrator mounted on the forward dragbox section, and with fasteners joining the forward and aft dragbox sections in an articulated manner relative to each other.

Abstract: A race sulky is provided with wheel guards that are each comprised of a pair of spaced-apart and opposed side shield surfaces, a nose shield surface that extends forward of the sulky wheel and joins the side shield surfaces into a U-shaped plan configuration, and fastener components that secure the joined side shield surfaces to the sulky wheel axle and sulky wheel fork.

Abstract: A system for use in winterizing/dewinterizing a watercraft marine engine is provided with a closed coolant storage tank having a cooperating pump, with an open coolant recovery tank having a separate cooperating pump, with coolant fluid transfer lines connecting the storage tank pump outlet to the recovery tank and connecting the recovery tank pump outlet to the storage tank, and a control for operating the storage tank pump and the recovery tank pump independently of each other.

Abstract: A medical needle and needle sheath assembly is provided with a sub-assembly of sheath elements that may be actuated from a retracted nested condition to an extended non-nested condition to both surround and extend beyond the medical needle element to provide protection to the medical practitioner using the assembly. A blocker element contained within the sheath sub-assembly provides additional protection against inadvertent injury to the medical practitioner when the sheath sub-assembly is in its extended condition, and further provides an obvious indication of the sheath sub-assembly retracted and extended states.

Abstract: A mower shield is provided for rear engine driven riding lawn mowers which shield includes a top panel having a rear portion, a central portion, and a front portion, and is positionable to overhang the leading edge of the deck by connection to at least one supporting element. More specifically, the supporting element suspends a section of the top panel over the deck such that its rear portion generally extends across the deck substantially in contact therewith, while a section of the top panel and the front portion are suspended beyond the leading edge of the deck. The air currents established by this mower shield cause such grass clippings as are expelled forwardly from beneath the deck to enter the chamber defined by the mower shield and be redirected downwardly, away from the operator. Flexible rear and front portions of the top panel permit clearing of debris, while transparent central and front portions of the top panel permit inspection and increase visibility of the cutting path.
