Abstract: A self-drilling fastener for use in a friable material with or without an underlying member at the point of use comprises an elongated body, a threaded exterior, an enlarged head with torque transmitting surfaces, proximal, intermediate, and distal portions, and a drilling tip generally opposite enlarged head. Proximal portion has an axial length, a threaded exterior having root and crest diameters and a thread height, where the crest diameter is about twice the root diameter. Intermediate portion has an axial length, a threaded exterior having a root, a crest diameter substantially smaller than proximal portion crest diameter and a thread height substantially smaller than proximal portion thread height. Distal portion has an axial length, a threaded exterior with a root that tapers toward the drilling tip, a crest diameter substantially smaller than the proximal portion crest diameter, and a thread height substantially smaller than the proximal portion thread height portion.

Abstract: A self-drilling anchor for use in a friable material comprises a body having an axis, a flanged rear end, a drilling front end and a generally cylindrical portion therebetween having an outer surface with a thread disposed thereon, wherein the body forks, beginning at a predetermined distance from the flanged rear end, into a first leg and a second leg, the first leg extending forwardly into a drilling tip, wherein the first leg may have a generally rearward facing shoulder angled obtusely outwardly with respect to the axis, wherein the body has an axial bore for receiving an elongate fastener, the axial bore extending substantially through the flanged end and leading to the generally rearward facing shoulder, wherein the anchor is adapted so that the first leg pivots apart from the second leg when the elongate fastener deflects the generally rearward facing shoulder and the predetermined distance is selected to increase pullout strength when the first leg is pivoted apart from the second leg and the anchor i

Abstract: An interlocking tile system comprises tiles that has a body, interlocking cap structure with a first surface and a second surface; a first curved portion connecting the first surface with a radius of R1 to the second engaging surface with a radius of R2, wherein R1>R2; and a stem supporting the cap structure. The cap is a mushroom-like shape. Such configuration of the connector aids in installation by lessening instances of binding and align and guide the caps into their corresponding receiving areas. The tiles are preferably square, and are connected along all four sides.

Abstract: A storage crate has a side access doorway, which is preferably closable by a hinged door. Preferred crates are also collapsible in some manner, most preferably using pivots disposed between the floor and two of the sides, and horizontally along in about the middle of those two sides. Depending on the configuration, collapsing can advantageously reduce the height of the crate by at least 50%, 75% or more. Preferred crates are also stackable, most preferably by virtue of at least two of the sides have sufficient wall strength such that one could safely stack of at least three of the crates when unfolded to an operating configuration, and when each of the crates are loaded with at least 10 kilograms of stored material.

Abstract: A floor or wall covering has blocks with mating strips having multiple ridges and multiple grooves in both mating members. Ridges and grooves can have different sizes and cross-sectional shapes from one another, and can mate in a manner that provides expansion gaps. Male/female positioning pairs can advantageously be included to facilitate alignment of the blocks during installation and use. Preferred floor blocks comprise a ribbed support portion that supports a working surface, and the ribbed support portion defines a plurality of cells that collectively reduce the weight of the block by a factor of at least 20% relative to corresponding block without such cells.

Abstract: A system and process for dispensing a liquid agrochemical such as ammonia into a field is disclosed. The ammonia is placed in a vessel under sufficient pressure to maintain a substantial portion of the ammonia in a liquid form. From the pressurized vessel, the ammonia is fed to a distribution manifold where it is ultimately injected into a soil through a plurality of dispensing tubes. A constant pressure flow rate control device is placed at each dispensing tube for metering the amount of ammonia fed to the soil. Furthermore, the outlet flow of each constant pressure rate control device is made to vaporize nearby the inlet flow path to create a heat exchange effect thereby cooling the inlet flow. In particular, the flow control devices allow ammonia to be dispensed from the system while maintaining sufficient back pressure and temperature within the distribution manifold to maintain the ammonia in a liquid form.

Abstract: A blow-molded or other plastic table has an internal frame. The internal frame preferably includes at least first and second support beams disposed lengthwise in the top, and more preferably also has both lateral and medial support beams, and a cross member that couples the lateral and medial support beams. The lateral and medial support beams need not extend the length of the table, and indeed in some embodiments they extend less than half the length of the table. Such a configuration allows the top to be manufactured, shipped, and stored in halves or other pieces. The lateral support beams can also be disposed to overlap, with or without touching one another. The top is preferably blow molded, and includes a core having a first plurality of baffles. Such baffles can be disposed in any suitable manner, including longwise and cross-wise.

Abstract: A storage system comprises a rack of multiple platforms connectable to one another in a first direction, where each of the platforms has segments that connect to one another along a direction other than the first direction, via a user-operable coupling. The platforms are preferably rectangular, and are connected at their long ends. The segments of each platform are also preferably rectangular, but they are connected along their long sides. In such embodiments, the connection between platforms is perpendicular to the length of the rack, while the connection between segments is parallel to the length of the rack. The segments of individual platforms are preferably coupled together with snap fit connections, and supported from their undersides by transverse supports, and the transverse supports are supported from their undersides by longitudinal supports. The transverse supports are preferably perpendicular to the longitudinal supports.

Abstract: A self-drilling anchor for use in a friable material comprises a body having an axis, a flanged rear end, a drilling front end and a generally cylindrical portion therebetween having an outer surface with a thread disposed thereon, wherein the body forks, beginning at a predetermined distance from the flanged rear end, into a first leg and a second leg, the first leg extending forwardly into a drilling tip and having a generally rearward facing shoulder angled obtusely outwardly with respect to the axis, wherein the body has an axial bore for receiving an elongate fastener, the axial bore extending substantially through the flanged end and the generally cylindrical portion and leading to the generally rearward facing shoulder, wherein the anchor has a drilling mode wherein the second leg nests behind the generally rearward facing shoulder of the first leg, and an anchoring mode wherein the legs are pivoted apart from one another.

Abstract: A formulation preparation device is provided herein which contains a valve assembly, transfer spikes, syringe port and tube, these components being interconnected so as to provide for controlled fluid flow between the spikes and port, through the assembly, in specific directions only. The device has an enclosed, sterilizable, gripable housing and can be used to mix combine fluids in reproducible and predetermined proportions. Combination is accomplished aseptically, avoiding contact between the device's operator and the fluids and the substances combined. Biologically active compounds can be combined with one or more fluids, including such aqueous liposome suspensions, using the device. A formulation preparation kit containing, in addition to the device, the fluids and compounds to be formulated is thus also provided herein; methods of using the device to prepare such formulations are further provided herein.
