Abstract: A steel rolling mill including a Steckel mill is provided with an in-line upstream quench station located downstream of the caster and upstream of the reheat furnace, a shear located downstream of the Steckel mill, and a temperature reduction station downstream of the shear. The upstream quench station has spray nozzles that quench a surface layer of the steel to transform same from an austentitic to a non-austentitic microstructure. The shear provides a precise transverse vertical face on the leading end of the steel. The temperature reduction station applies cooling fluid to the rolled steel so as to obtain a preferred microstructure that may be either bainite or martensite. If bainite, the temperature reduction station includes laminar-flow cooling apparatus; if martensite, the station also includes an initial rapid quench, in which latter case the station is followed by a tempering furnace.

Abstract: A changeable display element is edgewise mounted on an insulating board and carries to rotate through about 180.degree. to show one color face or the other to a viewer. The board provides a similarly colored face for each face to form a pixel. The element carries a permanent magnet and is driven by a switchable magnetic field provided from the board. Soft iron pads on the board cooperate with the magnet on each position to retain the element against incidental displacement between application of the field. The board may support arrays of such elements.

Abstract: A method for removing contaminants from fluids comprises contacting the fluid with an expanded material selected from popped corn, puffed rice and puffed wheat. The preferred expanded material is popped corn. The method is applicable to a wide range of organic and inorganic contaminants. Examples of contaminants include aromatic compounds such as polychlorinated biphenyls (PCBs), polychlorinated dibenzo furans (PCDFs), polychlorinated dibenzo dioxins (PCDDs), carbamates, sulphonamides, dichlorodiphenyltrichloroethane (DDT), 2,4-dichlorophenoxyacetic acid (2,4-D), other compounds such as carbon disulphide, ethylene glycol and pesticides. Other examples include inorganic compounds or organo-metallic compounds, e.g. those containing aluminum, antimony, barium, cadmium, cobalt, chromium, copper, iron, lead, mercury, molybdenum, nickel, silver, tin, titanium, vanadium and zinc.

Abstract: A weld bead chopper is provided, for use in combination with a scarfing tool which is intended to scarf a longitudinal weld bead from a tube. The chopper has a) a chopper blade which is rotatable about an axis which is substantially perpendicular to a longitudinal axis of the tube, and b) a stationary blade which is cooperable with the rotatable blade. The cooperating chopping surfaces of the rotatable and stationary blades are at a short distance from the weld bead, e.g. less than 100 mm, and preferably from 20 to 50 mm. The scarfed weld bead enters an enclosed throat which has walls to guide a scarfed weld bead towards the cooperating chopping surfaces. The throat has a first guide adjacent to the scarfing tool which directs the scarfed weld bead towards a second guide. The second guide faces the scarfing tool, and is adapted to guide the scarfed weld bead towards the cooperating chopping surfaces.

Abstract: Light indication apparatus for baseball includes a first light source for emitting first coherent and intense light rays of a first color in a first direction and a second light source for emitting second coherent and intense light rays of a second color in a second direction. The first and second light rays intersect entirely within a preselected volume. A baseball can be identified by an observer of said first and second light rays as being substantially within said volume when said first and second light rays shine on said object simultaneously.

Abstract: A computational field programable architecture targeted for compute intensive applications. The architecture is hierarchical and includes, for implementation of data path circuits, clusters of programable logic blocks that are designed to provide area-efficient realization of common arithmetic structures such as adders, subtracters and multipliers. The architecture includes a LUTb cluster for implementing the control part of a circuit. The programable logic blocks each include a stack of programable bit-slice logic elements each having 2 data inputs and a single data output, and a 1-bit full adder circuit. The bit slice logic elements allow bit-wise logic operations to be carried out and the programable logic blocks also include comparator logic to enable comparison operations to be performed. The bit slice logic elements each include a DFF at their output, and the DFFs in a programable logic blocks can be combined to form a register.

Abstract: An anti-theft device for securing a computer or office equipment component to a work surface. The device is adjustable for use with different sizes of components, and includes a generally U-shaped base member having an intermediate base frame and first and second parallel arms extending from the base frame and spaced apart to receive the equipment component to be secured therebetween. The base frame includes a base plate having a plurality of securing holes for receiving securing means to secure the base member to the support surface. The device includes a generally U-shaped clamping member having an intermediate clamp plate for engaging the office equipment component and first and second parallel arms extending from the clamp plate. The first and second parallel arms of one member are telescopically engaged with the first and second parallel arms, respectively, of the other member such that the base plate and clamp plate are opposed.

Abstract: A trap for mounting in a catch basin having a wall with a cylindrical opening provided therethrough. The trap, which is designed to impede floating pollutants from leaving the catch basin, includes a front plate member with an outlet opening, a rear plate member with an inlet opening, and a connecting member extending between and connecting the front plate member and the rear plate member. The trap is arranged so that it can be mounted to the wall of the catch basin by inserting it through the cylindrical opening. A further aspect provides a trap having a front plate member with an outlet opening and a rear plate member with an inlet opening, and connecting means for mounting the plate members on the wall of the catch basin. Also provided is a process for constructing a trap in a side wall of a catch basin, comprising steps of boring a cylindrical opening through the side wall with a coring machine and securing a front plate member and a rear plate member to the side wall.

Abstract: A combined enclosure for an industry standard electrical device, such as a switch or power receptacle, and a control device for controlling the electrical device, the control device having both controlled connectors and controlling connectors. The combined enclosure comprises an electrical device enclosure, a control components enclosure, and a dividing/mounting plate. The electrical device enclosure has an opening in the bottom defining two side ledges, and the top has a first mounting element adjacent to the front opening for mounting the electrical device in the electrical device enclosure. The control components enclosure has a top opening with side walls bent over to form flanges along sides of the top opening and fits through the opening in the bottom of the electrical device enclosure so as to hang by the flanges from the side ledges.

Abstract: An arm rest for a chair is disclosed that has an upper portion that swivels horizontally to support a user's forearm or wrist. The arm rest is removably attachable to a wide variety of chair arms. The arm rest includes a pair of parallel plates, one having a transverse opening therein adjacent to a forward end, and the other having a transverse shaft slidably located in the transverse opening for pivoting or swivelling the upper portion of the arm rest into a desired position. One of the plates is formed with a plurality of recesses arranged in a circle about the pivot axis, and the other plate has at least one locking pin extending into a selective recess to lock the upper swivelling arm rest portion in position. The upper arm rest portion is lifted or raised to disengage the locking pin. The swivelling arm rest portion is then rotated or swung into a desired position and released allowing the locking pin to engage another recess, again locking it in position.
