Abstract: A method for making a time-lapse seismic survey in a marine environment, the method designed to eliminate multiple surface reflections and changes in sea state and conditions. Seismic sources and receivers are positioned at predetermined conditions for a first set of data in which at least two sets of seismic signals are recorded at each receiver, proximate in time, such that there are insignificant changes in the subsurface formation. At a later point in time the seismic source(s) and receiver(s) are positioned at the same place when the first seismic data set was generated. A seismic source emits a sound wave and the seismic receiver receives what will be called a “monitor signal” and the two-way water travel time is again determined. A model is then developed for the first and second seismic data sets in that includes the subsurface signal, changes in the subsurface signal and the effect of multiple reflections.

Abstract: A system and method for balancing loads in a computer system is disclosed. The system and method assess the health of various paths in a computer system by determining the health or status of at least two layers on each path. A health or status of the paths is then determined based on the information of the health of each layer in the path. A load balancing device routes information for processing to the various paths based on the determined health of the paths. To better estimate the health of a path, algorithms which weight the health signals for each layer are used giving greater weight to layers of greater importance. The system and method can also add or remove additional paths if the combined health of the existing paths is determined to be above or below a predetermined value. In addition, the weight of certain layers can be locked in to provide for updating of specific layers.

Abstract: A filter device made of less expensive material than comparable filter devices heretofore has basic filter components plus some unique design aspects and an additional ring component. The ring provides an interface inside the filter which enables the potting compound to adhere to the filter and create a seal between a first and second fluid compartment within the filter. An embedded region of the ring possesses a detailed geometry which helps ensure that a delamination would be localized and unable to propagate from the first to the second compartment, maintaining the structural integrity of the filter device. To ensure that the sealing interface remains intact and free from delamination, the ring is subjected to a surface treatment, which modifies the surface energy of the ring. This modified surface energy of the ring allows the hydrophilic potting compound to more effectively bond to the modified hydrophobic ring.

Abstract: A switchgear assembly in which a number of cells housing electrical switching apparatus such as circuit breakers are vertically stacked in a forward compartment has combined arc shield/wire trays between cells for terminating secondary wiring for easy access through front doors on the switchgear assembly and for protecting the secondary wiring from circuit breaker arc gases. The arc gases are deflected by an upwardly and rearwardly inclined panel forming the back wall of the wire tray. A vertical wall forward of the inclined panel mounts a lower horizontal row of terminal blocks forward of an upper row. A wireway has a vertical section in a forward corner of the cabinet beside the vertically stacked cells which communicates with the wire trays, and a horizontal section extending rearward under the top wall of the cabinet. An inclined gutter provides a transition between the top of the vertical section and the forward end of the horizontal section.

Abstract: A tube squeezing device comprises a rectangular housing having a longitudinal slot formed in its front wall. The housing is pivoted to a backing plate which includes a tube retaining base for receiving and clamping the neck of the tube. A slide is arranged to slide within the housing, with the first and second rollers being mounted to the carriage. Each roller is provided with a slide advancing face and a tube squeezing face which are substantially perpendicular to each other, with a serrated and curved tube gripping face extending therebetween. The slide advancing faces define a nip which is slightly wider than a squeezed portion of the tube, thereby allowing the slide to move to a position in which the gripping faces or each roller abut the tube shoulders at the commencement of the unsqueezed portion of tube. Upon downward actuation of a lever, the rollers counter-rotate towards one another so that material from an adjacent unsqueezed portion of the tube may be squeezed.

Abstract: Main circuit breakers and/or tie circuit breakers are connected by upper and lower disconnects to upper and lower sections, respectively, of split risers in a low voltage switchgear assembly. An upper horizontal bus is connected to the upper sections of the split risers while a lower horizontal bus is connected to the lower sections. However, with the main or tie breaker mounted in the "C" position of a switchgear section, the gap between the upper and lower sections of the split risers is positioned vertically such that one of the phase conductors of the lower horizontal bus is above the gap. A unique connector extends downward from this phase conductor and is connected to the corresponding phase of the lower section of the vertical bus through the lower stab which engages the lower disconnect for the main or tie breaker.

Abstract: The interface conductors, stabs and runbacks, which are engaged at first ends by quick disconnects on electrical apparatus in a switchgear assembly, are fabricated from a stacked pair of elongated, flat conductors secured together at the first ends by elongated fasteners which are compressed into countersunk through apertures in the flat conductors to form a joint with no lateral projections. The interface conductors are supported adjacent the disconnects by a first support having a base member with through openings in which the conductors are snugly supported, and rigid projections with planar surfaces extending from the base member toward the quick disconnects alongside the openings and against which the interface conductors are secured adjacent free ends of the projections. A second support spaced rearward of the first support provides additional support for the runbacks. Interphase supports formed by C-channels are provided for the runbacks between the first and second supports.

Abstract: Hollow risers in switchgear are preferably formed by a confronting pair of spaced apart U-channels. Stab conductors for connecting switching apparatus in the switchgear to the risers have a pair of flat members straddling and secured to the two U-channels by mounts which include backing plates bearing against the inner surfaces of the confronting legs of two U-channels and bolts extending through the stab conductors and U-channel legs and engaging threaded apertures in the backing plates. To accommodate a range of current ratings, the confronting channels can have first and second leg thicknesses t.sub.1 and t.sub.2, which can be different but the outer widths of the channels are all the same. The backing plates have a first surface with a third thickness in one section and a fourth thickness in a second section. This first surface bears against the U-channel legs when the legs are of different thicknesses and t.sub.1 plus t.sub.3 is made equal to t.sub.2 plus t.sub.4.

Abstract: A flexible arrangement for providing secondary terminations, such as for switchgear in electric power distribution systems, includes a plurality of molded blocks each having at least one pair of oppositely directed hooks extending from a rear face. The hooks pass through complimentary notches in a mounting slot in a mounting panel, and engage the mounting panel with the molded blocks displaced along the mounting slot so that the hooks are out of registration with the notches. A locking member blocks the realignment of the hooks with the notches. Molded filler blocks without the terminal members can be substituted for one or more molded terminal blocks when fewer terminations are needed. There filler blocks have hand grips such as preferably a longitudinal rib molded on a front face, for inserting and removing the filler block from the slot.

Abstract: Heat sinks extending rearward from and connected to the risers of a switchgear assembly by the same fasteners which secure the stabs to the risers dissipate the joule heat generated by current flow through the risers and stabs and accommodate for the higher temperature rise permitted in the power circuit breakers engaged by the stabs. The heat sinks are formed by a pair of heat sink members straddling the risers, each of which has an elongated flat body with an extended flat mounting surface on a first face which provides extended surface engagement with a stab. The elongated body projects rearward beyond the stab and a first set of transverse fins project from the first face rearward of the stab toward the first set of fins on the other heat sink member of the pair.
