Abstract: A conveyor apparatus and method for a continuous haulage system and continuous conveyor belt are disclosed for carrying coal or ore. A middle roller and side sliders are connected with substantially flexible linkages on a roller-slider support piece supporting the continuous conveyor belt. Three apertures are positioned on the holding frame to adjust and control the tracking angle at which the support piece receives the continuous conveyor belt. In one aspect, the holding frame is provided by a plurality of floor-supported frame members held in position by belt tension, the holding frame being capable of rapid and efficient extendable, retractable construction in the mine, and wherein substantially flexible connecting linkages are positioned to connect the middle roller and the side slider and to connect the side slider to a holding frame for holding the roller-slider support piece. Rails connecting and hold adjacent frame members in position by press-fit attachment of the rails to the frame members.

Abstract: A gas-air flexible tubing assembly for use for interconnecting a supply of gas, such as bottled gas, to the burner of a cooking grill, the flexible tubing formed of helical coiled wire, and coated with a flexible and expandable polymer, interconnects with, at one end, and air-gas intake tube, by means of a threaded connection, and connects, at its opposite end, by means of a threaded connection with the downward extension of an adapter, for securement of the assembly to the underface of the burner element of a gas grill.

Abstract: A form-fit, disposable liner for a reusable plastic five gallon paint bucket. The liner is a thin, structurally rigid, single piece plastic liner formed by a suitable plastic molding process. The liner includes a cylindrically shaped side wall and a semi-circularly shaped bottom wall that conform to the side wall and bottom wall of the paint bucket. An integral roller landing extends down from a semi-circular shaped top wall at an angle thereto, into a vertically extending planar side wall. The roller landing includes a series of integrally molded ridges that allow a coating product stored in the liner to be loaded into a paint roller. A domed lid is provided that engages with a rim of the liner in a snap-fit engagement to allow the paint product in the liner to be sealed.

Abstract: An extensible conveyor apparatus and method for a continuous haulage system and continuous conveyor belt are disclosed for carrying coal or ore discharged from a continuous miner. A top roller combination supports the coal-carrying or ore-carrying continuous conveyor belt. A holding frame for the top roller and a bottom belt return is provided by a plurality of floor-supported frame members held and secured in position by belt tension. The holding frame is capable of rapid and nimble extendable, retractable construction in the mine. Rails connect and hold adjacent frame members in position by press-fit attachment of the rails to the frame members. The rails preferably are quickly rotatable to change the top wearing surface. A top roller for supporting the mined-material-carrying belt includes a combination of rollers formed into a roller combination insert which is quickly replaceable in an underground mine.
