Abstract: A exercise device includes: a u-shaped frame; first and second arms pivotally coupled to ends of the frame; a first pair of bands that resist pivotal movement between the u-shaped frame and each of the first and second arms; and an arm bar. The arm bar is releasably coupled proximate to the free end of each of the first and second arms. As configured the device is usable for a first set of exercises. A first end of each of a second pair of resistance bands is respectively secured in proximity to first and second ends of the arm bar. The second ends of the second pair of resistance bands have loops fixedly secured thereto. When the arm bar is not releasably secured to the first and second arms, it is usable in combination with those bands and loops for a second set of exercises, providing a full body workout.

Abstract: The apparatus comprises a plate cylinder 15, a blanket cylinder 16 and an impression cylinder 17. A web W passes between the blanket and impression cylinder to enable print to be applied to the web by the blanket cylinder. The plate and blanket cylinders 15,16 are provided as a one piece cartridge movable axially to a position offset from the web. The impression cylinder 17 is also movable independently of the other cylinders to a position offset from the web to enable the impression cylinder to be changed without breaking the web or removing the web from the apparatus.

Abstract: The apparatus comprises a printing cylinder for printing an element such as a paper web and feed and take-up rollers for the web. Sensors are provided for sensing the relative positioning of the web and the print which is applied to the web and the signals from the sensors are fed to a micro-processor. The micro-processor controls the feed and take up rollers so that if the relative positioning of the web is incorrect, the feed and take-up rollers are controlled simultaneously to move the web relative to the printing cylinder substantially without varying any tension in the web between the feed roller and the take-up roller.

Abstract: A method is disclosed for the reactive plating of substrates to produce transparent conducting films and photoactive coatings. Reactive gases at low pressures are introduced into a vacuum chamber having a partial vacuum therein. A substrate located in the vacuum chamber is subjected to a glow discharge in the partial vacuum. A coating material, such as zinc or silicon is vaporized in the vacuum chamber to react with the gases, with the resulting compound being deposited on the substrate by the effect of the glow discharge. The power in the glow discharge and the partial pressures of the vaporized coating material and gases introduced into the vacuum chamber can all be controlled separately to vary the stoichiometric ratios and the properties of the coatings. The electrode geometry is arranged and the operation maintained such that the power density distribution in the discharge is fixed and controlled.

Abstract: The invention relates to the handling of particulate materials such as foundry molding sand requiring cooling. The operating vessel has an inlet, through which material is charged to flow-downwardly in the vessel against an upward flow of pressurized fluid, usually air, there being provided sensing and signalling probes to sense the height of the fluidized material in the vessel at a pedetermined maximum level in the vessel and at a predetermined minimum level. These sensing and signalling probes control the outlet of cooled sand from the bottom of the vessel, stopping it when the minimum level is sensed and re-commencing discharge when the maximum level is reached.

Abstract: During scribing of a ceramic plate with a laser beam, ceramic particles rise from the workpiece in a direction of motion that is generally the same as that of the workpiece. The lens on a laser scriber is protected from abrasive contact with such particulates in the atmosphere by slipping the base of a housing over the circumference of the lens mount and forming a generally airtight seal between them. The housing is shaped like a frustum of a right circular cone, with the apex end thereof truncated and essentially rolled over to form an orifice through which the lens axis and laser beam pass. A plurality of streams of pressurized air are introduced into the housing near the midpoint of the frustum and the lens surface. The air streams are introduced tangent to the inner surface of the housing and angled downward for producing a vortex of air that is exhausted to the atmosphere through the orifice at a velocity and vorticity that inhibits particulates outside of the cover entering the orifice.

Abstract: An anode assembly for use in a system for the cathodic protection of a submerged, or partly submerged elongate metallic member the assembly being adapted to be fixed to and to encircle a length of said member. The assembly includes a plurality of generally flat, elongate electrically insulating panels of which at least one accommodates a metallic element which will constitute an anode in the aforesaid system, and a cable for providing electrical connection to the metallic element, the panels being adapted to be interconnected, in use of the assembly, and circumferentially disposed around the elongate member with part of the surface of the metallic element exposed outwardly of the elongate member. When so interconnected, the panels form a space between the assembly and the elongate member, and the assembly is apertured to permit electrical current to flow into this space to the elongate member from the metallic element when operating as an anode in the system.

Abstract: Rectangularly shaped snapstrates are separated into substrates along kerfs that are parallel to edges thereof by belt and roller flexure forces produced by two belts that are caused to be contiguous over the suspended length of the upper belt by a pressure roller forcing the two belts together at an intermediate point between roller supports for the belts. This produces oppositely facing curvatures in the belts at spaced apart transverse lines thereon which flex snapstrates in opposite directions with a flexure force which is sufficient to separate snapstrates on the lower belt with kerfs facing in the right direction and which is not sufficient to separate snapstrates there with kerfs facing in the wrong direction. In an alternate embodiment, the peripheries of rollers are tapered in vertical sections for separating snapstrates along kerfs oriented at right angles. In a further embodiment, only a single belt with a pressure roller pressing down on it is employed to separate snapstrates.

Abstract: This invention is a splash and spray control shield for the wheels of large vehicles, such as trucks and trailers, and is designed to control the wet weather splash and spray generated by the centrifugal force of the forward rotation of the wheels of such a vehicle traveling over wet road surfaces. This shield consists of a unit with sidewalls that covers the uppermost forward part, over the top of and the uppermost rearward part of the wheel or dual wheels, or wheels of adjacent axles. The uppermost forward section of this shield consists of an air collector known as a "scoop"--which is aerodynamically designed to collect and direct the flow of air caused by the forward movement of the vehicle, across the top of, backwardly and downward, behind the wheel or wheels or most rearward wheels of a set of adjacent axles, directly to the road surface.

Abstract: A vibratory feeder for conveying particulate material from one level to a higher level comprising an inclined, article-supporting surface, means for vibrating said surface, a plurality of baffles disposed in spaced apart relationship and spaced from the inclined surface with the baffles lying at an angle to the article-supporting surface.

Abstract: A substrate grader accepts or rejects a substrate depending upon the degree of warp and then sorts the accepted substrates according to a dimension thereof. The grader comprises a first plate which is U-shaped and inclined at an acute angle with respect to the horizontal, the two arms of the first plate extending above the base thereof. A first elongated member (or lower guide) that is attached to the front of the base has a straight side which is adjacent to and spaced a short distance away from the opening in the first plate. A second elongated member, that is attached to the back of the free ends of the arms, supports a second plate (or upper guide) thereon which extends between the arms, which has a top surface in a plane containing the top surfaces of the arms and base, and which has a stepped edge in the opening.

Abstract: Printed circuit boards are moved in a conveyor with the underside of flat boards spaced a prescribed distance above the top surface of a rotating cutting disk. In order to protect the circuit patterns on the underside of the board and the board itself, a V-shaped wheel is loosely rotatably supported on a shaft with the wheel being in front of and orthogonal to the cutting disk. The height of the wheel is adjusted such that the uppermost point on the circumference thereof is in the line of travel of the boards. Movement of a board that is bowed downward in the direction of the disk causes the wheel to roll on the underside of the board and to raise the board above the top of the cutting disk. In this manner, the underside of warped circuit boards is maintained at least a prescribed distance above the top surface of the cutting disk as the board moves over the leading - cutting edge of the latter and component leads are trimmed thereby.
