A stocking cart conveyance may include three tiers, wherein the lower and middle tiers are substantially full length and the upper tier is substantially shorter to improve user sight lines, cart maneuverability, and/or accessibility to items in the middle tier. The upper tier in illustrative embodiments may be approximately 70-80% of the length of the full length tier(s) so as to maintain significant storage volume while still providing improved access, maneuverability, or sight lines. The upper tier may optionally be hinged so as to further improve user accessibility to items placed on the second tier. In illustrative embodiments the carts may longitudinally nest into one another to reduce the space needed to store the carts, and in certain embodiments the carts may be configured to nest when the upper tiers are in an upright position.

A registration device is used to couple an identification superstructure of a surgical navigation system to the spinal column. The registration device includes a pair of vertebral engaging members positionable in a spinal disc space. At least one of the vertebrae engaging members moves outwardly from a collapsed position to engage the registration device to the endplates of the adjacent vertebrae.

A bottom-loading multi-axial bone anchor apparatus is disclosed. The apparatus includes a receiver member, a crown member, a bone anchor and a retaining member. The receiver member defines an upper opening and a lower opening, which may form part of the same opening, a channel, and a groove. The crown member and bone anchor are loaded into the lower opening of the receiver member, and the retaining member fits around the bone anchor and into the groove in the receiver member. The bone anchor is capable of multi-axial positioning with respect to the receiver member. An elongated member is placed in the channel of the receiver member, contacting the crown member, and a compression member is applied via the upper opening. The compression member presses down on the elongated member, which presses down on the crown member and locks the bone anchor between the crown member and the retaining member.

A peck feed drill incorporates a motor gear quill and a feed control assembly together on a moving race track shaped piston. External construction of the housing permits mounting of an indexing adaptor plug for attachment of drill bushings. Internal construction of the housing provides for passage of air to the various components to which control tool operation. Valves within the air logic circuitry are multi-functional to minimize the number of parts.

A double wall, light-weight tank construction for the storage of flammable liquids is formed from two conventional steel tanks having flame proof, curable cementitious insulative material between the walls. Spacers preformed preferably of the same cementitious material are glued about the exterior surface of a conventional inner tank having ports. An exterior tank is formed with one end cover being detachable. Apertures are cut in the exterior tank to align with the ports of the inner tank when it is in its final nested position within the exterior tank. Stoppers and vents are placed in a sidewall of the exterior tank. Both tanks are oriented vertically, and the interior tank is then lowered into the exterior tank with concentric alignment provided by the spacers. Nipples are then attached to the ports, and rings are placed over the nipples and welded to the nipples and the exterior tank. The detached end cover is welded to the exterior tank. The assembled tanks are placed horizontally or may remain vertically aligned. Mixed cementitious insulating material in plastic-phase is then pumped upwardly via the sidewall or the bottom stopper to fill the space between the tanks in a single application. The cementitious material is then cured, excess moisture is drained away, and the stoppers and vents are sealed to complete the tank construction.

The present invention provides a strap for securing a garment or article (e.g. swimming goggles) to a wearer's/user's body. The strap comprises a first portion (1) having a tensioner end (2), the tensioner end including and terminating at a tensioner (3). The strap further comprises a second portion (4) comprising a clip end (5), the clip end including and terminating at a clip (6). In use, the second portion passes through the tensioner and the clip is releasably securable onto the second portion.
摘要:
A process for locationally sorting and filtering mobile applications at a geographical level, utilizing location-specific information is disclosed. The ability to filter categories among location-specific displayed application results in an interface creates much greater additional value to consumers, as they can quickly and easily screen applications pertaining to “Dating,” “Transportation” or other categories near them, where both location and underlying functionality are equally important. Additionally, browsing is encouraged under this system, as users do not have to continually enter new terms and hit search to generate new application search results.

Anti-extrusion devices, packer elements, and inflatable packers include shape memory polymer (SMP) materials to enhance the operation of a packer, a bridge plug, or other downhole isolation tool. Seal system use seals of various material including SMP materials as booster for the seal produced. Tool for flow shut-off and sliding sleeve applications use SMP materials to open or close off flow through a tool.
