Abstract: A conveyor sled assembly is utilized to supply proppant in support of oilfield hydraulic fracturing operations. The conveyor sled assembly includes precisely positioned components where tolerances between components are so small as to prevent significant spillage at component junction boundaries. This manner of fitting proppant pods onto the conveyor sled assembly increases predictability of which pods will discharge their proppant load first. This enhances reliability of the overall proppant delivery system.

Abstract: A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. A metering conveyor is positioned between a blender tub and a proppant motive mechanism, such as a conveyor or wash system that receives discharge direct from proppant containers of the type normally used to transport sand in support of a hydraulic fracturing operation. The metering conveyor is fitted with equipment including an intermediate surge hopper with a vibration system and a knife-edge gate that may be used to facilitate the operational movement of sand.

Abstract: A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The proppant container is part of an overall system that is used to move sand for use as proppant, and is fitted with a vibration system that facilitates the discharge of sand from the container.

Abstract: An implant has a soft tissue attachment structure, and a surface defining a trough. An ingrowth plate spans a portion of the trough and defines a suture tunnel between the ingrowth plate and the trough for receiving suture. The ingrowth plate bows convexly away from the surface and is perforated to facilitate long-term ingrowth and biologic fixation of soft tissue to the implant.

Abstract: A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The proppant container is provided with a system for dislodging the wet sand for subsequent use. This may be done by use of a vibrator or an umbrella valve. In another aspect, the proppant container may be used in combination with a rack having a wash system that slurries the proppant for delivery to a blender tub without necessarily resorting to use of a conveyor belt.

Abstract: The present disclosure relates to systems and methods for generating orthotic device models using simulated patient anatomy. In one implementation, a method comprises receiving images of a body part of a patient; deriving physical measurements from the images; generating anatomy model data of the body part using the physical measurements; and generating orthotic model data based on the anatomy model data, the orthotic model data being representative of an orthotic device.

Abstract: A container or pod is specially constructed for hauling proppant in support of oilfield hydraulic fracturing operations. Dimensions are provided that comport with common dimensions in use for transportation of intermodal containers, with the containers being sized so as not to require special permitting from a regulatory standpoint when two such containers are loaded on a single trailer. A method of filling the containers is also provided, which include inverting the container to fill from a bottom gate that also serves as the discharge opening when the filled container is rotated back into an upright position.

Abstract: An insert to be used with footwear is provided. In one implementation, the insert includes a structural member that has a first surface and a second surface opposite the first surface. The first surface is shaped to correspond with contours of a user foot. The second surface is adapted to rest on substantially planar surface. The insert includes a recessed cavity defining an opening from the first surface to the second surface of the structural member. The recessed cavity is shaped to stabilize a region of the user foot placed within the opening. An intermediate layer is attached to the structural member in a mating relationship with respect to the first surface. This foam layer is adapted to distribute a determined amount of foot pressure from the user foot with respect to the structural member.

Abstract: A method and system of performing secure credit card purchases in the context of a remote commercial transaction, such as over the telephone, wherein only the customer, once generally deciding upon a product or service to be purchased, communicates with a custodial authorizing entity, such as a credit card company or issuing bank wherein such entity has previous knowledge of the credit card number as well as custodial control of other account parameters such as interest rate, payment history, available credit limit etc. The customer supplies the custodial authorizing entity with the account identification data such as the credit card number and a requested one of a possible plurality of predetermined payment categories which define the dollar amount for the purchase and specific, predetermined time parameters within which authorization by the custodial authorizing entity will remain in effect.

Abstract: A tilt or rake adjustable steering column having a first or tilt lever locking mechanism and a second locking mechanism separate from the first locking mechanism. The second locking mechanism has a pivotable eccentric cam or locking wedge that engages a fixed member to hold the adjustable steering column in the event the first locking mechanisms fails. The tilt lever locking mechanism is linked by a spring to the second locking mechanism so that movement of the tilt lever locking mechanism from a locked position to an unlocked position moves the pivotable eccentric cam from an engaged position to a non-engaged position.
