Abstract: A user wearable wrist support formed of low temperature moldable, formable plastic, normally closed-cell foam laminated between surface sheets of fabric. The wrist support comprises a curvate clasp having a generally self-supporting C shaped cross section, with the clasp encircling the wrist of the wearer. The clasp is secured in position by a strap. A palmar stay extends transverse of the clasp onto a palmar pad integrally extending from a side of the clasp. In one embodiment the clasp is provided with outwardly extending wrist support rests alongside the stay for supporting the clasp on a planar surface. In another embodiment the support comprises two sheets of plastic material of different densities and hardness sandwiching and embedding a stay therebetween. The device is fabricated by first creating a sheet of foam laminated with at least one surface fabric sheet. Blanks for forming the clasp are cut from the foam sheet and subjected to selective compression, heat, and molding to form the support.

Abstract: An improved method and apparatus for increasing the productivity of a direct reduction process in which iron oxide is reduced to metallized iron by contact with hot reducing gas; comprising the steps of: a) providing a first hot reducing gas consisting essentially of CO and H2; b) providing additional reducing gas by reaction of a gaseous or liquid hydrocarbon fuel with oxygen; c) mixing the first hot reducing gas with the additional reducing gas to form a reducing gas mixture; d) enriching the reducing gas mixture by the addition of a gaseous or liquid hydrocarbon; e) injecting oxygen or oxygen-enriched air into the enriched mixture; and f) introducing the enriched mixture into an associated direct reduction furnace as reducing gas.

Abstract: The invention relates to a swivel adapter-coupler that is to be positioned between a conventional fixed drop elbow on the end of a hose of a tanker truck for an underground storage tank. The other end of the swivel adapter-coupler attaches to the pipe adapter (either the fill pipe or the vapor pipe) of the underground storage tank, in the conventional quick-connect type connection. The swivel adapter-coupler permits loops and kinks in the hose to be removed by rotating the swivel adapter-coupler in the proper direction. Likewise, the invention relates to a rotatable drop elbow to replace the conventional fixed drop elbow at the end of a hose on a tanker truck. The rotatable drop elbow eliminates loops and kinks in the hose by merely rotating the drop elbow in the proper direction.

Abstract: A head and neck restraint device, worn by a driver when operating a high performance vehicle, which controls the driver's head from snapping forward and maintains the driver's head, neck and spine in general alignment in the event of a frontal crash. The device includes a pair of anchor straps that are worn along the back of the driver and have first end which connects to the driver's helmet by use of hooks and tethers, and second ends which extends between the driver's legs for connection to a seat belt assembly. A chest strap and a waist strap are attached to the anchor straps for keeping the anchor straps separated at a predetermined distance. When exiting the vehicle, the driver unlatches a standard vehicle seat belt assembly and the restraint device is simultaneously released from the vehicle. Since the restraint is neither rigid nor bulky, the driver can quickly exit the vehicle unrestricted by the device.

Abstract: A flow sensor component consists of a diaphragm of monocrystalline silicon, the diaphragm having arranged therein filled slots which are filled with a thermally insulating material and which penetrate the diaphragm from a first main surface to a second main surface thereof. The filled slots defining at least one heating area of the diaphragm provided with at least one heating element and at least one detection area of the diaphragm provided with at least one temperature detection element, the filled slots thermally insulating the heating area and the detection area from one another and surrounding the heating area and the detection area completely.

Abstract: An improved method and apparatus for charging, preheating and refining steel. The charging apparatus has a skirted charging section for introducing charge materials, a dynamic gas seal adjacent the charging section and a preheater, the preheater for preheating the charged materials, a connector adjacent the preheater and removably insertable into an electric arc furnace for feeding charged materials into a furnace bath for melting and refining metallic charge therein, and a vibrating conveyor which extends throughout the charging apparatus. The charging apparatus is positioned on rails to be movable by a hydraulic cylinder between a charging position wherein the connector is fully inserted into the furnace, a retracted position where the connector is partially inserted into the furnace and a disconnected position where the connector is fully removed from the furnace.

Abstract: A method and apparatus for simultaneously cutting and directing fluid into the stem of a tabacco plant, the apparatus including having a liquid delivery blade, a source of fluid communicating with to the underside of the blade, an associated power source for rotating the liquid delivery blade at a sufficiently high speed “top” tobacco plants.

Abstract: In accordance with the present invention there is provided an upper body support characterized by a dorsal member, having a lower portion which extends substantially rearwardly of a wearer, and at least one flexibly resilient element operatively interconnected with the lower portion of the dorsal member so that when the wearer bends at the waist, the dorsal member operates on the or each flexible resilient element in such a manner that the weight of the upper body of the wearer is borne at least partly therethrough.

Abstract: An apparatus and method for processing liquid slag and baghouse dust from a steelmaking furnace such as an EAF to recover valuable metals from the slag and dust includes a treatment vessel having a movable lower shell portion for receiving liquid slag and an upper shell portion that couples with the movable lower shell portion during heat activation of the treatment vessel. The slag is combined with silicon dioxide, a reducing agent, baghouse dust, and an inert gas before being heated to between approximately 1400° C. and 3000° C. The heat treatment results in a molten reduced iron and manganese metallic material, a treated slag layer, and an off-gas containing lead, zinc, and carbon monoxide. The off-gas is combusted, cooled, and solidified, resulting in lead oxide and zinc oxide. The slag layer is tapped, cooled, and solidified. The metallic layer is tapped for recycle in the steel making process.

Abstract: A volume sensor-free microdosing device comprises a pressure chamber which is at least partly delimited by a displacer, an actuating device for actuating the displacer, the volume of the pressure chamber being adapted to the changed by actuating the displacer, a media reservoir which is in fluid communication with the pressure chamber, an outlet opening which is in fluid communication with the pressure chamber, and a control mechanism.

Abstract: The present invention is an apparatus and method for the direct reduction of iron oxide utilizing a rotary hearth furnace to form a high purity carbon-containing iron metal button. The hearth layer may be a refractory or a vitreous hearth layer of iron oxide, carbon, and silica compounds. Additionally, coating materials may be introduced onto the refractory or vitreous hearth layer before iron oxide ore and carbon materials are added, with the coating materials preventing attack of the molten iron on the hearth layer. The coating materials may include compounds of carbon, iron oxide, silicon oxide, magnesium oxide, and/or aluminum oxide. The coating materials may be placed as a solid or a slurry on the hearth layer and heated, which provides a protective layer onto which the iron oxide ores and carbon materials are placed. The iron oxide is reduced and forms molten globules of high purity iron and residual carbon, which remain separate from the hearth layer.
