  • Patent number: 10569920
    Abstract: This disclosure provides compositions, films, labels, structures and methods that may include a substrate having a first side and a second side, wherein the first side comprises a skin layer comprising at least 50 wt. % of high-density polyethylene. Further, the compositions may include a coating on the skin layer, wherein the coating comprises a topcoat and a primer, wherein the topcoat consists of: (i) at least 50 wt. % high-density polyethylene and one or more polyethylene polymers in water; (ii) wax, silicone or combination thereof; and (iii) optionally additives, whereupon imaging the composition by a thermal print head at a temperature of 300° C. or less results in no or negligible solvent-penetrability beneath the skin layer.

  • Patent number: 9592429
    Abstract: A tennis court ball retainer having a horizontally extending ball gutter along the tennis court back wall which has an upwardly facing channel dimensioned to receive and retain tennis balls. An upright flexible upper backdrop curtain coextends directly above and along the ball gutter for engaging tennis balls striking the upper curtain, thereby dampening the tennis ball impact and directing the engaged tennis balls to fall into the ball gutter for retention. A tennis court floor surface ball retainer is also provided and coextends with and under the ball gutter. The ball gutter extends a uniform distance above the tennis court floor surface and includes an upright flexible lower backdrop curtain coextending below and along the ball gutter for engaging and trapping tennis balls striking this lower curtain by rolling or skidding on the tennis court floor surface.

  • Patent number: 4602438
    Abstract: A method and apparatus for drying low-rank coals, such as lignite, where the coal is passed through a sealed vessel in a plurality of heated fluidized beds, with fluidization effected by superheated steam flowing countercurrent to the coal flow. A composite steam is exhausted from the sealed vessel and passed to a vessel where water is sprayed therein to cool the same and remove occluded solids. A first portion of the steam is then reheated and returned to the sealed vessel as fluidizing steam, while a second portion of the steam is heated and passed through heat exchange tubes in the sealed vessel to heat the fluidizing coal, with the second portion, after passage through the heat exchange tubes discharged from the system.

  • Patent number: 4601115
    Abstract: Low-rank coals, such as lignite, are dried by evaporating interstitial water therefrom in a superheated steam flow countercurrently passed through a sealed rotary cylindrical vessel. A composite steam discharged from the vessel is partially condensed to remove an amount of water therefrom substantially equal to the amount of water removed from the coal, with a resultant flow of residual steam reheated and returned to the cylindrical vessel for further drying of low-rank coal.

  • Patent number: 4601113
    Abstract: A method and apparatus for drying of low-rank coals, such as lignite, where the coal is passed through a sealed vessel in a plurality of heated fluidized beds with fluidization effected by superheated steam flowing counter-current to the flow of coal. A composite steam is exhausted from the sealed vessel, partially condensed, to remove an amount of water about equal to that removed from the coal, and the steam reheated and recycled to the sealed vessel. The heating of the fluidized beds is by means of heat exchange tubes passing through the beds, with a fluid, such as methanol, heated for flow through the tubes, collected and in a cooled state used in the partial condenser, and then compressed to reheat the same for reuse in the heat exchange tubes.

  • Patent number: 4479419
    Abstract: A multi-cylinder compressor 10 particularly useful in connection with northern climate heat pumps and in which different capacities are available in accordance with reversing motor 16 rotation is provided with an eccentric cam 38 on a crank pin 34 under a fraction of the connecting rods, and arranged for rotation upon the crank pin between opposite positions 180.degree. apart so that with cam rotation on the crank pin such that the crank throw is at its normal maximum value all pistons pump at full capacity, and with rotation of the crank shaft in the opposite direction the cam moves to a circumferential position on the crank pin such that the overall crank throw is zero. Pistons 24 whose connecting rods 30 ride on a crank pin 36 without a cam pump their normal rate with either crank rotational direction. Thus a small clearance volume is provided for any piston that moves when in either capacity mode of operation.

  • Patent number: 4391158
    Abstract: A manual shift transmission having multiple input and output portions is provided with a control having input and output shift rails. A laterally movable control shaft extends axially through cutouts in respective shift rails and carries cams adapted to cooperate with cam follower surfaces on corresponding cutouts to effect rectilinear movement of the shift rails upon rotation of the control shaft. The cams are arranged on the shaft so that the shaft may be positioned to place respective cams in register with the input and output shift rails while all other cams are out of register with the rail cutouts. The shift movement of respective output and input shift rails is overlapped during the rotation of the control shaft to decrease the throw of the shift lever. The control shaft is spring biased to provide variable resistance in response to movement of a control lever to enable the operator to determine his position in the shift pattern of the transmission.
