  • Patent number: 6941628
    Abstract: The invention comprises tools for forming beads on one or more filaments using a malleable material for the bead. The tools exert bead-forming forces radially inward toward the filament and axially along the filament toward the center of the bead. The tools comprise pliers with jaws which meet flush with each other over at least a portion of the jaw face. Aligned cavities are formed in each jaw face wherein each cavity's dimension across the jaw face is less than the width of the jaw face. Grooves, aligned generally transverse to the width of the jaw face provide a filament-receiving channel between the cavity and the edge of the jaw face. Malleable material encompassing the filament is aligned between the aligned cavities and the jaws are closed. The radial force of the cavity walls on the malleable material deforms the malleable material radially and the walls of the cavity exert a force axially to form a bead.

Replacement of the flexible (rubber) impeller has proven to be difficult, particularly for larger pumps located in the confines of an engine compartment of a boat and for impellers encrusted with salt, sand or otherwise stuck to the pump shaft. To aid in extracting impellers, an end piece on the impeller has been added such that a tool having flanges can be inserted into a space between the end piece and the impeller. The end piece on the impeller can also be used as an end plate to engage a threaded shaft for jacking the impeller onto a pump shaft. An alignment cone can be added to the pump housing for aligning the impeller with the pump shaft and pump housing bore.

  • Patent number: 6378191
    Abstract: The present invention relates to a door jack formed of a lever arm having a first end formed as a foot pedal and a second end connected by a hinge or universal joint to a doorholder. In between the two ends of the lever arm a pivotal piece acting is located on the underside of the lever arm. When a workperson places his foot on the foot pedal and thus presses down the door holder in which the door 14 is contained lifts upward causing the door to be lifted vertically to any desired height. By moving the pedal in the horizontal plane, e.g. parallel to the floor the door will move in the horizontal plane in the opposite direction of the direction of the foot pedal due to the articulating member, e.g. the hinge or the universal joint. This causes the door to aligned in place.

  • Patent number: 6336264
    Abstract: A connection bolt arrangement typically used for connecting two structural members to each other, for example in aircraft construction, includes a conically tapered connection bolt that is force-locked or frictionally engaged in an expansion sleeve so as to cause a radial outward expansion of the sleeve and thereby tightly hold the structural components. An apparatus for releasing such a connection bolt arrangement includes two levers that are pivotably connected to each other, a stamping actuator arranged between respective first ends of the two levers, a pulling extraction device mounted at the second end of the first lever, and a pushing block mounted at the second end of the second lever. The actuating force applied by the actuator is transmitted through the levers and applied to the connection bolt and to the expansion sleeve in opposite directions so as to tend to push the bolt out of the sleeve.

  • Patent number: 6220169
    Abstract: The invention relates to a method of placing, positioning and fastening railroad sections on railroad rail sections (1) on a number of mutually adjacent and mutually spaced, loose railroad sleepers (2a, 2b), with the aid of a pulling vehicle (7) which functions to pull a rail section (1) from a first railroad wagon (4) into abutment with said sleepers, via a second railroad wagon (5). Rail sections (1) pulled from the wagon by said vehicle (7) are moved linearly at a distance (a) above the sleepers (2a, 2b) with the aid of a number of devices (10, 10a, 10b). This linear movement is adapted so that the trailing end-surface (1′) of the pulled rail section will be positioned adjacent a leading end-surface (1″) of an earlier laid rail section. In this position of the rail section, one or more of said devices (10, 10a, 10b) is/are activated to lower the rail section (1) onto rail-adapted, sleeper-associated fastener elements (81-84).

  • Patent number: 6216339
    Abstract: A tool-actuated ejector for extracting electronic modular components. The ejector, which functions as a levered cam, has a body with a first end, a second end and a pivot located intermediate the first and second ends. A tool-receiving socket mounts at the second end. A tool, such as a screwdriver with a blade that matches the shape of the socket, actuates the ejector by applying a force to the socket. A cam, located at the first end, engages the electronic modular component. To provide a mechanical advantage, the distance between the tool-receiving socket and the pivot, which constitutes one lever arm, is greater than the distance between the cam and the pivot, which constitutes a second lever arm. In addition, a shock absorber mounts on the body and gliders extend below the body to provide stability and balance to the ejector. The ejector mounts in a casing having a tool passage that communicates with the tool-receiving socket and the exterior of the casing.
