Abstract: The embodiment of a spinal fixation system 10 including a pair of longitudinal members 11, 12 positionable adjacent the spine, engaging member for engaging longitudinal members to the spine 13, 14, a pair of wedge members 16 each having a bearing surface 38 configured to bear on a longitudinal member 11, 12, and a connector 20 configured to span a distance between the longitudinal members 11, 12. The connector 20 includes a pair of engaging members 25, 26 each having a fixation surface 33 and a connecting surface 30, and a bridge member 21 attached to the connecting surfaces 30. The engaging members 25, 26 each define a thru-hole 35 for receiving one of the wedge members 16. The thru-holes 35 are aligned so that when one of the wedge members 16 is advanced through the thru-hole 35, the bearing surface 38 will bear on a corresponding longitudinal member 11, 12 to force the longitudinal member 11, 12 into contact with the fixation surface 33 and engage the longitudinal member 11, 12 to the connector 20.

Abstract: A noise attenuating system for suppressing noise on circuit board transmission lines is provided. A first ferrous member is attached to a first side of the circuit board and a second ferrous member attached to a second side of the circuit board. The second ferrous member is substantially opposed from the first ferrous member, such that conductive transmission lines are contained between the first ferrous member and the second ferrous member. Transmission line interference is absorbed and suppressed by the first ferrous member and the second ferrous member. In a preferred embodiment, substantially all traces which enter and exit the circuit board on a connector pass between the first ferrous member and the second ferrous member. Apertures in the circuit board allow the ferrous members to adjoin forming a ferrous core.

Abstract: The present invention is directed to methods and compositions for biological control of plant diseases using suppressive avirulent strains of Streptomyces spp. to control disease on a vegetable or other susceptible crop. The method includes applying one or more naturally occurring, suppressive avirulent strains of Streptonmces spp. to the crop to inhibit the growth of Streptomyces scabies or other plant pathogenic organisms that cause scab, wilt, or seedling blight disease. Preferably, at least two suppressive avirulent strains of Streptomyces spp. are applied to reduce the change of resistance from occurring. The suppressive avirulent strains ame compatible and will grow in the presence of one another and, when combined with the pathogenic organism, at least one of the suppressive avirulent strains preferably substantially outgrows the pathogen.

Abstract: A cover includes a side panel having an opening therethrough. A sliding member is connected to the side panel, and is slidable to an opened position in which the opening is at least partially uncovered, and is slidable to a closed position in which the opening is closed. A mounting is tab connected to the side panel and is arranged to be accessible through the opening only when the sliding member is in the opened position. A front panel is also provided, which can be fastened and locked to the side panel using no visible fasteners.

Abstract: An electrical cabinet includes at least one modular enclosure connectable to at least one of a further, substantially identical modular enclosure, and a pedestal enclosure. The modular enclosure has a generally parallelepiped shape, with at least one space therein for the placement of components. A cover is positionable over the exterior sides of the enclosure, and includes a modular rear cover section positionable over the rear side of the modular enclosure to essentially hide the rear side of the modular enclosure from view.

Abstract: One embodiment of a spinal fixation system including a pair of longitudinal members 11, 12 positionable adjacent the spine, means for engaging longitudinal members to the spine 13, 14, a pair of wedge members 241 each having a bearing surface 242 configured to bear on a longitudinal member 11, 12, and a connector 200 configured to span a distance between the longitudinal members 11, 12. The connector 200 includes a pair of engaging members 205, 212 each having a fixation portion 207, 214 and a connecting portion 209, 216, and a bridge members 202 attachable to the connecting portions 209, 216. The engaging members 205, 212 each define a thru-hole 225 for receiving one of the wedge members 241.

Abstract: A direct access storage device (DASD) cage holds a DASD sled which contains an electronic DASD. The sled has a base plate, side walls and a front portion. The cage has side walls and a forward panel. Each side wall of the cage has a groove for receiving an outer edge of the base plate. The front portion interfaces the DASD with a machine connector. The sled has a slidable handle and a pair of pivotable latches which engage the handle. Each latch has an inner finger and an outer finger. Each inner finger engages a slot in the handle while each outer finger moves inward and outward. Stops in the base plate limit the travel of the inner fingers. The handle is pulled rearward to a disengaged position before the sled is installed in the cage. The outer edges of the base plate are placed in the grooves and the sled is pushed forward into the cage. When the sled is half-way into the cage, the latches will partially engage the grooves to stop the movement of the sled.

Abstract: A slot ventilator (100, 500) comprises a slotted backing member (24, 124, 424, 524), an elongate facing strip (26, 126, 426, 526, 626), and a linkage mechanism connecting the backing member and facing strip with one another, the linkage mechanism being arrange to permit generally translational forward and backward movement of the facing strip between a closed position in which the slot is closed and an open position in which the facing strip is spaced in front of the backing member. The linkage mechanism includes a hinge (58, 158, 300) allowing the facing strip to rotate about a longitudinal axis to vary the angular orientation thereof. When installed horizontally in a window frame (14, 588, 588') the facing strip may be moved forwards and backwards to increase and decrease ventilation, and may be rotated about the hinge to divide incoming ventilation favourably between downward and upward directions.

Abstract: A spinal implant system for correcting spinal deformities and abnormalities includes an elongated spinal rod configured to be implanted adjacent the spinal column and spanning across several vertebral levels. A number of fixation elements, such as spinal hooks, are provided for engaging vertebrae at a number of vertebral levels. At least some of the fixation elements includes an elongated stem projecting from a vertebra engaging portion. The stems of each of the fixation elements are connected to the spinal rod by way of a rod connector having a one-piece body defining a rod channel adapted to receive the spinal rod therethrough, a stem bore adapted to receive a stem therethrough, and a threaded bore. The stem bore and rod channel intersect to permit contact between the rod and the stem of a fixation element. The threaded bore intersects either the rod channel or the stem bore so that a set screw threaded into the threaded bore bears against the spinal rod or fixation element stem.

Abstract: A transvenous cardioversion lead system capable of delivering electrical energy to cardiac tissue is provided. Lead system comprises an inner conductor surrounded by an insulative layer which, in turn, is surrounded by a second conductor mounted coaxially with the inner conductor. At least a portion of the second conductor is surrounded by an outer conductive sheath formed from a suitable material having an non-abrasive affect. This prevents damage to cardiac tissue during normal transvenous operating position while at the same time preventing thrombogenesis on the lead surface.
