Abstract: This invention relates to building materials and methods. A building assembly for constructing a building includes load bearing structural panels joined and finished with a non-load bearing panels. The load bearing panels comprise a structural concrete insulating panel (SCIP) comprising a pair of wire mesh members sandwiching a middle member comprising polystyrene, wherein each of said wire mesh members defines two outwardly projecting screed ridges. The non-load bearing panels comprise a pair of fiber cement boards sandwiching a polystyrene core. The load bearing SCIP panel is placed in position and then the non-load bearing panel is positioned in a desirous location abutting the SCIP. The SCIP then receives a layer of cementitious material that is cut flat using the screed ridges. The assembled SCIP and non-load bearing composite is then finished with a final finishing layer so that the entire assembly has the same outer appearance.

Abstract: A vertical grilling apparatus employs food cartridges on rails to slideably insert the food cartridge into the housing of the grilling apparatus between two thermal elements for cooking the food items. The rails correspond to a vertical slot, or opening, in the housing for engaging the food cartridge. The food cartridge is sized to correspond to a top and bottom rail and to the vertical slot. The food cartridges have hinged sides which close or clamp to an opposed position for engaging and securing the food items in a food specific insert on the hinged sides sized to accommodate the food item. The horizontally disposed food cartridge is rotated to a vertical orientation after closing and securing the food items for insertion into the vertical slot. The insertion disposes the food cartridge equidistant between the opposed thermal elements for thermal communication with the thermal elements for cooking the food.

Abstract: A nephelometer for detecting the concentration of particulates in a sample aerosol is provided with a branched flow path with a sample aerosol input, a clean gas input and an output leading to an optical sensor unit. At least one of the inputs has periodic variable flow so that a concentration-modulated gas stream is supplied to the optical sensor unit. The detector output of the sensor unit is processed in synchrony with the concentration modulation to filter out DC components, such as 1/f noise and parasitic instrument noise.

Abstract: A convective accelerometer capable of measuring linear or angular acceleration, velocity, or angle of inclination is provided. The accelerometer comprises sensing elements that are sensitive to convection located inside a sealed housing containing a liquid agent. Applied external acceleration causes forced convection of the liquid agent, which produces variations in an electric current produced by the sensing elements that are proportional to the applied acceleration or angle of inclination. The accelerometer has a small size, extremely wide frequency and dynamic ranges, high sensitivity, simple design and is suitable for mass production. The device has a wide range of application, such as stabilization and control systems, homeland security, and oil exploration.

Abstract: A duct reinforcing rod and fabrication apparatus for use with a conduit and a threaded element dimensioned to fit within the conduit includes a positioning device to position the conduit at an insertion position and an insertion device for inserting the threaded element a predetermined distance into the conduit. A deformation device is also employed to deform the conduit such that the deformation occurs at two locations on the conduit, the two locations being longitudinally spaced from one another along a length of the conduit.

Abstract: A seam for ductwork has a male end portion integrally formed at a distal end of a duct wall and a female end portion integrally formed at another distal end of the duct wall. The female end portion includes a first fold and a second fold, which define a female groove for accommodating the male portion. A distal end of the second fold is bent transverse to the female groove prior to the male portion being inserted into the female groove.

Abstract: An expansion shell assembly for mine roof bolts includes an expansion member threaded onto an associated mine roof bolt. A support device is annularly disposed around the associated roof bolt. An expansion shell is annularly disposed around the associated roof bolt between the expansion member and the support device. The expansion shell has a base ring for engaging the support device and fingers for engaging a peripheral edge of the expansion member. The engagement between the base ring and the support device permits axial traverse movement of the support device relative to the expansion shell for tensioning the roof bolt.

Abstract: An apparatus and process for recovering metals from aqueous solutions by passing an aqueous solution, which contains dissolved metals, into a space between two elongated electrodes of a treatment chamber. A very high voltage electric field is created in the treatment chamber and is accompanied by a very small trickle current charge to enhance adsorption, polarization, ion exchange or to otherwise agglomerate the dissolved metal, which is then recovered by filtering, adsorbing, exchanging or otherwise separating the metal from the water.

Abstract: The invention provides a separating vessel (10) suitable for use in the treatment of a mineral sample wherein a molten slag (11) is separated from a molten collector material (12) comprising a container defining an interior cavity (13) for receiving the molten materials (11, 12), an outlet aperture (14) leading from the interior cavity to the exterior of the container, and a separating surface (15) associated with the outlet aperture (14) which is shaped to cause droplets of flux (11a) to be carried along such surface, while droplets of collector material (12a) drip off such surface by the force of gravity.

Abstract: A security module for use with a ventilation grating comprising a body, a base with a planar surface for attachment to the grating, and an outer wall extending from the base. The body has inner passageways extending from the base to the outer wall, the first portion of which extends from the base in a direction perpendicular to the base, and the second portion of which extends from the outer wall to intersect perpendicularly with the first portion within the body. The security module, when attached to a ventilation grating, prevents threading a rope-like material, through the grating, and using the make-shift rope to commit suicide by hanging, and is therefore particularly suitable for use in penal institutions, hospitals and mental health facilities.

Abstract: A semi-automatic gift or package wrapping method and apparatus is disclosed. The apparatus includes a machine frame that provides a work surface with measuring and wrapping sections. A sheet feed and cutting mechanism feeds paper from a role in two steps with a time pause in between for enabling a user or operator to partially wrap the package with part of the first section of dispensed paper web. Thereafter, the second section of paper web is dispensed and the web cut transversely at a trailing edge. Multiple selectable supply rolls are optionally provided, or a single roll machine can be used. Longitudinal cutters trim the sides of the paper to obtain a custom desired width for the full cut sheet. A user interface display controls machine functions such as start, continue and sheeter. In the sheeter mode, a selected number of sheets of a selected size can be dispensed and cut for use at another workstation to warp other boxes of known uniform size (i.e. shirt boxes at a department store).
