Abstract: A power tool (10) is provided having a plastic casing (12) and a scraper blade (14). The blade (14) is caused to reciprocate by an internal low power rotary motor (24) which drives a cylinder cam (28) having a sinusoidal cam track (34). A pair of studs (36) ride in the cam track (34), and drive the reciprocal movement of the blade (14). The tool (10) is substantially sealed against liquid ingress by means of an elastomeric membrane within the casing (12), and may be used as a marine growth remover, for defouling boats and the like.

Abstract: A number of cam-operated devices such as power tools (10) are described, the tools having a rotary drive device (24) for rotating a drive shaft (36) having a cylinder cam (42) mounted thereon. A pair of cam followers (54) are located within a cam track (44) provided on the cam member (42), such that rotation of the cam (42) causes axial movement of the cam followers (54), which may be attached to a drive shaft (48) and a tool bit (12). A range of shapes of cam track (44) are described, each of which is non-sinusoidal in shape. Various embodiments of the invention provide non-sinusoidal cam tracks having forward or rearward throw sections which are respectively steeper, shorter, or provide greater acceleration of the cam followers than sinusoidal cam tracks of equivalent wavelength and amplitude. Related piston and cylinder devices and reciprocal drive devices are also described.

A concave shaped substrate has an inside surface and an outside surface, wherein a minimum distance from the inside surface to the outside surface that is generally set by the substrate thickness is substantially constant throughout the substrate. An affixment material secures the first and second ends of the fused portion to the inside surface of the substrate. A thermally conductive housing is in thermal contact with the outside surface of the substrate. In one embodiment the substrate has an L-shaped cross section and the housing is a hollow housing that has a rectangular cross section.

Abstract: Methods and systems for discovering whether a given connection to an InfiniBand port is a standard InfiniBand connection or a non-standard connection (e.g., indicating the presence of a proprietary device) are provided. The discovery may be performed by an end node, such that the end node interoperates with all standard InfiniBand components. Specific actions that are vendor unique, and potentially not compliant with the InfiniBand architecture, may not be done until after the discovery is complete and it has been verified that the noncompliant action will only be directed to entities know to be capable of processing them. These actions may include assuming the configuration responsibilities that would have been performed by the Subnet Manager in a standard InfiniBand network.

Abstract: Methods and other embodiments associated with performing an in-memory triangulation of an arbitrarily large data set are described. One example method for performing in-memory triangulation of an arbitrarily large data set includes striping a data set into multiple stripes, selecting a first stripe to triangulate, and then performing an in-memory triangulation on the stripe. The method may also include removing certain triangles from the triangulated irregular network produced by the triangulation, merging another stripe with the leftover data, and repeating the process until the arbitrarily large data set has been triangulated piece-by-piece, with the triangulations occurring in memory.

Abstract: An actuator includes an electromagnetic coil arrangement that is movable relative to a magnetic field generator between a first position and a second position of the actuator. The actuator is arranged such that when the actuator is in the first position, a pulse of current through the electromagnetic coil arrangement produces a region of magnetic field that repels the magnetic field generator from the first position and attracts the magnetic field generator towards the second position to move the actuator to the second position.

Abstract: An apparatus (10) for use in boring is described, the apparatus including a rotatable drive shaft (12), a cam member (20) and followers (16) for converting rotational motion into reciprocal motion, and a shroud (24) having a cutting edge (26) driven by the cam member and followers. The shroud may be selectively engageable with the cam member and followers, allowing the drive shaft to be removed through the shroud. A fluid circulation arrangement (31), (13) allows air to be injected into loose drilling substrate, so assisting removal of drill cuttings from the boring apparatus. Also described is a drill string incorporating a similar arrangement, allowing the drill string to be reciprocated within a bore. The drill string may further include casing sections, which may have intumescent coatings to allow the sections to be fixed in a wellbore.

Abstract: Hsp110 proteins are shown herein to stabilize nascent ApoB protein. Methods of down-regulating expression of ApoB, and thus down-regulating serum cholesterol levels, are therefore, provided, including, without limitation, inhibition of Hsp110 expression by any method, for example and without limitation, by RNA interference (RNAi). It also has been found that ApoB gene-containing cells are useful in identifying compounds and genes that affect the expression of longer forms of ApoB. Lastly, a firefly luciferase-derived polypeptide is shown herein to bind the peptide binding site of Hsp110, thus serving as a powerful analytical reagent for identifying compounds, such as small molecule compounds, that would interfere with Hsp110-moderated stabilization of ApoB.

Abstract: A lock mechanism has a manually actuable element, a lock lever and an actuator, with the manually actuable element connected to the lock lever via a transmission path. The transmission path includes a rigid link with an end defining an abutment for selectively driving the lock lever.
