  • Patent number: 5163311
    Abstract: A progressive rollformer machine is readily adjustable, without removal of rolls or use of spacers, to produce sheet metal workpiece margin flanges of variable depth. The machine includes a gear train housing having perpendicularly extending spindle shafts and idler gear shafts, and two forming roll housing sections, with their rolls mounted outboard. One of these, conventionally fixed relative to the gear train housing, provides one reference line of forming. The other forming roll housing section provides a second reference line of forming--it may be positioned at a variable distance from the gear train housing, at a spacing adjustable by a screw drive. Tracking throughout all roll stations is made possible by using the adjustable-position forming roll housing first in line of flow, with supplemental tracking rolls mounted onto the ends of the spindle shafts.

  • Patent number: 5112423
    Abstract: Plastic lettering material having a polyvinyl chloride display layer fused with greater adherence onto a release sheet. Including partially carboxylated polyvinyl chloride in the display layer provides substantially increased adhesion, as does a heat-stabilized polyester release sheet. A layer of non-encapsulating thermoplastic adhesive capable of substantially permanent adherence to a smooth substrate is adhered to the display layer surface opposite the release sheet. Outlines of individual lettering elements which together form a sign content are cut through the adhesive and display layers while the release sheet remains substantially uncut, and that portion of the display and adhesive layers not included in the outlines is stripped away. This leaves the lettering elements firmly adhered to the release sheet, maintaining them in alignment during positioning on and heat bonding to a permanent substrate.

  • Patent number: 5064440
    Abstract: The effect of chlorine concentration in laundry solutions on the life of the laundered fabrics is signalled by a chlorine concentration indicator swatch, in which contrastingly hued dyes, including one whose chlorine resistance is measurably stronger than the other, are combined to dye fabric test swatches an initial color. Including such fabric test swatches in chlorine-containing laundry solutions causes visually discernable changes in the hues of the swatches as the bleaching action progressively subtracts those dyes of lesser resistance. Chlorine concentration which, if excessive, seriously impairs laundered fabrics, may be determined by visually inspecting the swatches.

  • Patent number: 5042614
    Abstract: Interactive component parts for assembling an ATV-mounted hunting stand of either the "A"-frame type or tree-leaning type, or alternatively as a ground-standing tree-leaning hunting stand. It includes a leveling seat platform, ladder elements, quick-grasping base connector assemblies, and a ground support. The seat platform has angularly-adjustable sockets so sized as to fit onto the upper ends of ladder elements, whose lower ends may have sleeves to allow these ladder elements to be mounted atop other ladder elements. Base connector sleeve assemblies allow ladder elements to be quickly and easily mounted on and demounted from rods attached to an ATV; they are free to pivot about these rods. When such ladder elements are so mounted on an ATV as an A-frame hunting stand, changing the angularity of the seat sockets effects seat leveling. For ground-standing ladder use, a broad ground support may be inserted into the lowest ladder element.

  • Patent number: 4954095
    Abstract: The present invention consists of a cable especially suited to the transmission of audio-frequency signals, cable in which one or more of the conductors is tubular. The conductors are constructed and spaced so that the assembly approaches theoretical and empirical ideals of electrical signal transmission. Further, the cable's terminations are designed to enhance transmission by bringing the conductors into direct contact with the connectors on the devices with which the cable is used.

  • Patent number: 4948705
    Abstract: A highlight mask, especially suited for printing from positive color transparencies, is made of photochromic glass which, like Corning PHOTOGRAY EXTRA sunglass lens material, darkens not only under ultraviolet radiation but also under visible radiation in the blue range. The mask is made by mounting, onto its upper surface, a photo transparency and exposing it to flashes of intense light strong in the blue range. Such radiation penetrates the thin or highlight areas of a photo transparency, regardless of their color tint, and creates a negtive highlight-masking image in the glass. While it does not effect general contrast reduction over the entire film area, the highlight masking image requires no further development, remains in registration with the transparency for photoprinting, and fades in time or when heated, so that the glass may be reused.

  • Patent number: 4946355
    Abstract: A positive displacement pump is particularly adapted for corrosive, abrasive and viscous liquids. It employs a combination of orbital and nodding movements provided by a unique mechanism. A rotor member, mounted eccentrically on a drive shaft, fits closely within a pumping chamber which it drives in an orbital path along an inclined plate having fluid inlet and outlet ports. The resultant cyclic increase and decrease in volume of the chamber beneath the rotor member draws in fluid and discharges it under pressure. For fluids of greater viscosity (or where reduced flow rate is desired) the angle of tilt is reduced, without lessening the power afforded for pumping.

  • Patent number: 4924848
    Abstract: A furnace utilizing, in the upper portion of its cabinet, a blower acting downward through a separator opening to circulate room air past a combustion chamber whose gases flow upward through a sideward-positioned board radiator member which reaches up to the flue. A substantial increase in efficiency results from drawing the combustion gases out of the combustion chamber at the side opposite to the lower end of the broad radiator member, and interposing therebetween, directly beneath the separator opening, a plurality of tubes which serve as an intermediate heat exchanger. A still greater increase in efficiency is achieved by utilizing, instead, a finned tube heat exchanger across and beneath said separator opening; its heat transfer may be so great as to result in condensation of water vapor in the combustion gas. To purge this, a motorized inducer-blower is used in the inlet air system, driving the condensate through the finned tube heat exchanger to an appropriate drain.

  • Patent number: 4865013
    Abstract: A self-adjusting, telescoping concentric flue assembly provides non-separating, substantial flexibility between the telescoping sections of both the flue and the air supply ducts. The lower flue and air supply ducts may move radially independently of each other sufficiently to permit installation even on a furnace having somewhat non-concentric flue and air inlet connections. Attachment of the lower air supply duct to the furnace insures that the lower flue is likewise attached, yet the lower air supply duct can be raised independently of the lower flue to check the connection of the latter with the furnace flue connection.

  • Patent number: 4834358
    Abstract: A modular fixturing system is provided, whose typical use is holding each of a series of similar workpieces, such as rough castings, during machining. It is conventional to support such workpieces during machining on permanent fixtures, specially designed for each type and size of workpiece, each such fixture utilizing two or more locating pins through parallel bores in the workpiece. In the present invention, locating pins are not part of any permanent fixture; instead, using a fixturing plate drilled with bores at modular intervals, the present adaptors are secured at any required spacing, and locating pins of desired diameter are mounted in them. One of the adaptors, referred to as "fixed", is mounted directly to one of the modular bores of the fixturing plate. The other adaptor to be used will be one whose position is slidably adjustable along linearly aligned slots in its base.

  • Patent number: 4835043
    Abstract: Adding sodium sulfite in the slurry of the iron oxide slurry process for scavenging hydrogen sulfide described in U.S. Pat. No. 4,246,244, eliminates excessive foaming on start-up, stabilizes the suspension of the oxide particles in the slurry, lessens clogging of reacted particles, which otherwise interferes with cleaning out the reactor vessel, and so materially buffers the slurry as to minimize corrosion of the reactor vessel and piping. Further, adding small amounts of oxygen to the gas stream, which would be expected to cause corrosion, does not do so; instead it prolongs the usefulness of the reactant oxide particles and affords increased acid-stability to the reaction products.

  • Patent number: 4832325
    Abstract: An adjustable adapter, expecially useful for modular fixturing has provisions for mounting a variety of types and sizes of spring stop buttons and spring locating pins. These are secured in linear alignment with a slot in the adaptor base. When used to press a workpiece against stops, the reaction of their applied spring force is directed precisely along the line of this base slot. A single bolt in the slot thus suffices to secure the adaptor to a base plate, because this reaction causes no twisting moment about the point of bolting. Since only one bolt is required in the slot, the adaptor is compact and well suited for use with a modular fixturing plate; the slot length need be no longer than half the modular spacing of the plate bores.
