Abstract: A needle assembly has an elongate hollow handle with a proximal end with provisions for attaching a fluid handling device and a distal end with an opening. The assembly has a needle with a distal point, a proximal end and an open passageway. The assembly also has an elongate substantially transparent needle hub with a distal end portion that has the needle fixedly attached. The needle hub is disposed for coaxial slidable movement within the hollow handle from a first position wherein the needle projects outwardly from the handle. The needle hub includes an elongate flashback chamber inside that is fluidly connected to the needle for viewing flashback. The needle hub is operatively biased for axial movement from the first position to a proximal rest position within the handle. When the needle hub is in the proximal position, the needle is substantially contained within the handle. The hollow handle has a latch thatreleasably retains the needle hub in the first position and an operative trigger to release the latch so that the operatively biased hub moves axially. The assemblyhas a hollow flexible tube inside the hollow handle extending from the proximal end of the hub to the attachment for the fluid handling device. When the hub is in the first position, the tube connects the flashback chamber to the attachmentfor the fluid handling device. When the latch is released and the needle hub moves to the proximal rest position, the flexible tube substantially collapses.

Title: Placing and cementing casing in horizontal wells
Inventor: WEBB EARL D
IPC: E21B33/16
Filed: 1997-11-06
Abstract: Improved methods and apparatus for placing and cementing a casing string in a horizontal well bore section are provided.          A float shoe is attached to the end of the casing string and a float collar is connected in the casing string for trapping air in a first portion of the casing string thereby causing it to be buoyed up during placement by drilling fluid contained in the well bore.  A selectively openable and releasable closed baffle assembly is connected within the casing string for trapping air or a low density fluid in a second portion of the casing string thereby causing it to also be buoyed up by drilling fluid in the well  bore.   The buoying up  of  the  casing  string reduces placement drag and consequent compressive loading on the casing string.  After placement, the closed baffle means is opened to allow fluid circulation and conditioning of the annulus.   A bottom cementing plug is then landed on the baffle assembly and the baffle assembly is released and moved to the float collar. A cement slurry is thereafter placed in the annulus and allowed to set therein.

Abstract: A device for interconnecting the bare ends of two or more optical fibers (18, 20) uses a common receptacle (12) having a fiber clamping element (66) therein and camming surfaces (70, 72) for actuating the element (66), and at least one plug having a camming finger (74, 76) for engaging one of the camming surfaces (70, 72). The camming surfaces (70, 72) are located such that, when only one of the camming surfaces (70, 72) is actuated, the clamping element (66) rocks to a side of the pocket opposite the one camming surface (70, 72) and remains in the open state, but when both of the camming surfaces (70, 72) are actuated, the clamping element (66) is forced to the closed state. The plug includes a fiber protector (22) free to slide within the plug housing (14, 16), substantially enclosing the bare end of the fiber (18, 20) when the plug housing (14, 16) is removed from the receptacle (12), but retracting when the plug housing (14, 16) is inserted into the receptacle (12) to direct the bare end of the fiber (18, 20) toward said guide tube (64). A fiber collet (26) biases the terminal end of the fiber (18, 20) toward the forward end of the plug to place a preload condition on the bare end of the fiber (18, 20). The connector (10) is particularly suited for cleave-and-bevel installations. The receptacle (12) preferably uses a novel clamping element (90) having two plate members (92, 94) with fiber-contacting surfaces, at least one of said fiber-contacting surfaces having a fiber-receiving groove (108). Edges (96, 98) of the plates (92, 94) are aligned and held together with a split tube spring (112). At least one of the plate members (92, 94) is provided with a wire-receiving groove (100, 102) and a wire (114) therein which acts as a fulcrum to allow the plates (92, 94) to pivot along an axis defined by the wire (114).  The split tube spring (112) provides a precisely controlled load along the edges (96, 98) of the plates (92, 94) allowing the opposite ends to be clamped together (within the guide tube (64)) by a force sufficient to overcome the controlled load of the split tube spring (112).

Title: Container and condiment cup for refridgerated dough or like products
Inventor: CAHILL GLENDA
IPC: A23L27/00
Filed: 1998-04-27
Abstract: A container for refrigerated dough or other expandable products and a condiment cup therein for containing icing and the like includes the following construction. The container has an elongate cylindrical body with an interior wall of a predetermined diameter and end closures. The condiment cup is of a flexible plastic generally cup-shaped construction having a generally cylindrical side wall closed at one end by a dome-shaped convex end and open at the other end. The cylindrical side wall has an outside diameter only slightly less than the diameter of the container interior wall so as to provide a loose friction fit when the condiment cup is positioned within the container cylindrical body portion. The condiment cup is filled with condiment and positioned within the container at one end of the cylindrical body portion with the open end of the cup facing the end closure at the one end. The container is filled with refrigerated dough or other expandable product, so that, as the product expands within the container, the product will push against the dome-shaped convex end of the condiment cup for flexing the cup end inwardly to cause flexing of the cup side wall outwardly to provide a tighter friction fit with the container interior wall to seal the condiments in the cup from the product in the container.

Title: Improved 10si alternator housing to accommodate larger heavy duty 17si rectifier
Inventor: KARAM RAYMOND N
IPC: H02K11/04
Filed: 1998-07-06
Abstract: Briefly, high output "popular" small frame alternators have a high rate of failure due to higher heat temperatures typically caused by; 1) continuous higher rate charging, 2) lack of heat dissipation through rectifier heat sinks & diodes, 3) insufficient cooling (air exchange/air flow) through alternator and components, 4) the "plugging up" of alternator by foreign matter such as chaff, dust etc...as is common in agricultural, mining and industrial applications and therefore limiting cooling causing "burn out". The invention consists of an improved alternator CE housing to allow for a larger rectifier with larger heat sinks (and thus its exposed surface area) and 9 50amp diodes vs. the original 6 25amp diodes (and thus increasing its current carrying capability) as well as an improved more open design in the housing and rectifier to allow for more air flow and a cooler running, more durable alternator.
