Abstract: A cellular drainage structure is formed of a predetermined volume of a settable, water permeable, cellular concrete product. A concrete mix is formed of a uniformly graded aggregate in the size range from 1/16 inch to two inches and in a quantity corresponding to the predetermined volume; a cementitious component in the quantity range from 141 to 658 pounds per cubic yard of product; water in quantity sufficient to create a water-to-cement ratio in the approximate range from 0.30 to 0.55 and sufficient to wet the aggregate, establishing a cementitious-component-and-water matrix of determinable volume; a pre-formed surfactant foam, generated from an aqueous surfactant mixture at a dilution of from approximately 3 to 25 grams per liter of surfactant in water, wherein the pre-formed foam is in the density range of from 2.0 to 3.0 pcf, and the foam is added in the quantity range of 5% to 30% of the volume of the cementitious-component-and-water matrix.

Abstract: A central turret rotates continuously on a central axis and carries a plurality of planetary turrets that rotate on their own axes. An index drive intermittently moves each planetary turret through a cycle consisting of both a period of rotation through a fraction of a revolution on the planetary turret axis and a period of dwell at an indexed position. The planetary turrets each carry a plurality of tool heads, and during successive periods of dwell, a successive one of the tool heads is presented to a workstation. A workpiece carrier supports a workpiece in proximity to the workstation. Rams operatively engage the workpiece and tool head as the successive tool heads dwell at the workstation. In this way, a workpiece is processed by a plurality of tool heads during a single revolution around the central axis.

Abstract: A die (104) for forming a blank (14) into a container body (26) having an open end provides an annular undulated shaping surface (106) of substantially uniform radius. The container body (26) is formed by moving the blank through the shaping die (104), with the result that the undulations (106) laterally redistribute metal in the sidewall of the container body, as well as iron the sidewall during the forming process. The die enables the use of a blank (14) of noncircular geometric shape, such as a hexagon, by redistributing metal from the points of the hexagon to the area of the flats in order to produce an end product without excessive earing.

Abstract: A split tipped catheter for cavitary entrance has a conical distal tip with a bore sized to receive an introducer needle. The conical tip wall is split on one side, permitting the wall to be opened by a spreading tool to clip the tip over the introducer. A fascial knife carries a blade with its tip protruding from the distal end of a backing plate, and a clip on the backing plate also engages the introducer needle for precisely incising the fascia in advance of the catheter.

Abstract: The addition of urease negative bacteria to sodium smectite clay minerals in pet litter inhibits growth of urease positive bacteria for a period of several days, thereby retarding formation of ammonia and other obnoxious odors. Approximately fifty percent sodium bentonite in the litter causes the litter to clump upon wetting, maintaining the urea in contact with the treated clay and also serving as a buffer to favor growth of the urease negative bacteria.

Abstract: In this process for the treatment of waste products, the waste products are separated in a first and a second group with respective pH-value of maximum 7 or higher than 7. The waste products of the first group are made increasingly acid whereas those of the second group are basified. This is done by adding an acid to the first group and a base to the second group in order to obtain a pH-value of maximum 5 for the first group and a pH-value of minimum 8 for the second group. An oxidant and metallic precipitating reagents are added to the first group of waste products. The thus treated waste products are combined in an alkaline mixture that is absorbed in a polymeric matrix by adding reaction components for the formation of a polymeric matrix.

Abstract: A container body is produced from a blank, by first forming the blank from sheet stock in hexagonal shape, thereby eliminating scrap from the blanking process. A die ring is configured to laterally redistribute material from the point areas of the hexagon into intermediate areas during the draw-and-iron can forming process, usefully incorporating this material instead of trimming it.

Abstract: An anticaking agent which reduces the stickiness of the chunked, diced, or shredded cheese and improves the functionality of cheese is formulated of fine mesh vegetable flour, bentonite, cellulose, and antimycotic agents or bacterial cultures. This anticaking agent also will reduce the yeast and mold growth. This discovery is also extended to include various flavors, colors, enzymes and other supplements into the anticaking agent, to ultimately add to the cheese.

Abstract: In a multi-section conveyor, a conveyor section provides a belt tension adjusting mechanism employing extension arms on an expanding tensioner. The extension arms carry the end belt roller and apply increased tension to the belt as the arms extend. The opposed end rollers of adjacent sections are joined to coaxial end gears, and an intermediate idler gear interconnects the end gears when the sections are joined. When sections are assembled, the extension arms mate into the neighboring section and are contoured to permit angular variation in the mating. A latching mechanism on one section locks the end roller of the next section in engagement slots and boxes the gears for safety.

Abstract: A concrete form mold unit formed of a lightweight, insulative material defines at least two rows of vertical core spaces, offset from each other. Concrete and reinforcing rods fill the core spaces, defining post structures. The top of the form mold unit is troughed and is filled with horizontal reinforcing rods and concrete, defining beam structures. The form mold units are laid in courses and stacked as required to build walls, with vertical cores and horizontal troughs aligned, producing an efficient utilization of concrete in the posts and beams. Each course is filled with concrete before the next course is added. The form mold unit is retained as an insulative part of the building structure, with a low dead load. Vertical attaching plates are placed on the surface of the wall, with penetrating fasteners passing into an underlying concrete post or beam. Surface finish materials are joined to the attaching plates.

Abstract: A shoe hoop, adapted for use in combination with a sewing machine, provides a rigid frame mountable in a fixed position with respect to an associated sewing machine. A sole plate carried within the frame has spring-loaded clamps that hold a shoe firmly to the plate. Pivot mechanisms position the sole plate at various angular dispositions within the frame and permit depth adjustment of the sole plate.

Abstract: A bulk container of pressure dispensable product receives a supply of gas from a plurality of containers arranged in operative series and, optionally, nested. Gas pressure is supplied by mixing at least two components of a multiple component gas generating chemical system, in which the containers in series initially house alternating ones of the gas generating chemicals. Delivery tubes connect the containers, define the series, and supply chemical from one container to the next to generate gas and regulate pressure. Pressure generation is initiated by adding the appropriate chemical or pressurized gas to at least one container, such as the container operatively furthest from the bulk container.

Abstract: A weather resistant soil cement with an open pore structure for resisting freeze-thaw damage is formed of cement, fly ash, Free aggregates, water, and an aqueous foamed surfactant, and other application specific additives. The material is uniquely suited for using indigenous soils, mill tailings, or granular waste products as the aggregate component of the mixture, although commercially produced aggregates may be used depending on economics and availability. Due to its low density and flowable nature, it can be pumped or placed by gravity and without compaction. The resulting product is a low density material with construction and mining applications, that is suited for use as a fill or mad base. Specific product formulations are easily designed to permit removal at local sites with conventional excavating equipment.

Abstract: A collapsible snowshoe is constructed of an elongated frame having right and left side bars and front and rear end bars. A web extends between the end bars of the frame. A shoe binding is attached to the frame above the web and between the right and left side bars for pivotal motion along a transverse pivot axis. A resilient member urges relative pivotal motion between the shoe binding and the frame along the transverse pivot axis, causing the front of the frame to be urged upwardly with respect to the shoe binding.

Abstract: A weapon sling having a weapon release run and a weapon carrying run has a fastener with an L-shaped pivoting lever mounted near the stock end of weapon release ran. A rectangular lock ring is attached to the stock end of the weapon carrying run. The lock ring is engageable over the L-shaped lever, which can pivot over the ring to deposit the ring against an inclined surface of the fastener that retains the ring against accidental loss under tension applied to the sling.

Abstract: A rack for storing and displaying apparel belts provides an elongated slot bounded by parallel edges for receiving a coiled belt, which is retained between the edges by friction from the compression of the expansive coil. The rack is provided with mounting mechanisms that permit combination of multiple racks, mounting of the rack to a vertical or horizontal surface, or suspension from a closet rod.

Abstract: A trigger (18), containing one component (28) of a two component gas generating system and having a headspace (37), is closed by a pressure rupturable membrane (36) and located in an expandable pouch (10), in a reservoir of the other component (19) of the gas generating system, with the membrane (36) facing down. The pouch (10) is inserted into a dispensing container (44) for flowable product, and the container is sealed. Thereafter, the trigger (18) is activated by externally pressurizing the container by back flow of fluid through a dispensing valve (46), either by adding a gas or by adding flowable product, causing the membrane (36) to rupture and the trigger (18) to discharge its contents into the reservoir of the other gas generating chemical (19).
