Abstract: ABSTRACT OF THE DISCLOSURE      A disposable package for dispensing liquids with a controlled rate of flow is described, such as for syrup for use with a post-mix soft drink dispenser.  The disposable package includes a thin walled plastic or glass container with a closed end and an open end defining a discharge opening with a flow rate control tube positioned in said container in a predetermined position.  The flow rate control tube has a closed rupturable, openable or fran-gible sealed end, which extends through the closed end of the container, and an open end, which is disposed at a predetermined distance within the container from the position of the discharge opening.  The discharge or open end of the container is sealed by a removable cap and a rupturable membrane.  In use with a post-mix dispensing device, the cap is removed and the container inverter or placed with its open end down for insertion into the dispensing device.  The dispensing device is provided with a piercing device which ruptures the membrane across the open end of the container to permit fluid flow from the container into the dispenser.  Once the container is inserted within the dispenser, the openable end of the flow rate control tube is opened by rupture or by removal of a seal and, thereafter, the flow rate control tube will effec-tively control the rate of flow of liquid from the container into the dispenser.  The sealed end of the flow rate control tube may be contained within a recessed portion of the container adjacent the closed end thereof to protect the sealed end from rupture during shipping of the disposable package.  A check valve may be placed at the open end of the flow control tube to preclude spillage in operable condition when the package temperature is elevated and the trapped head-space expands exerting back-pressure.

Abstract: Abstract:      The layout of an open pit mine for tar sands ore facilitates the handling of the ore by employing two or more cuts that diverge from each other while extending away from a common dump adjacent a processing (extraction) plant. Successive parallel and adjacent strips of overburden and ore are removed, whereby each cut is widened and deepened. As a result, each adjacent pair of cuts open to a common track.  Initially, this takes place in the vicinity of the dump, but, as mining proceeds a track (or ramp) is formed that is common to the two cuts while leading from each cut to the dump.  This provision of a common track shortens the haulage routes involved.  The ore is mined with large power shovels and loaded into large trucks, this equipment working down on the ore body.  For stability, a firm surface (roadway) is formed on the ore to support the shovels and trucks.  A major advantage of the system is flexibility of movement between pits and lack of restriction in mining depth and much improved ability to separate ore and reject.  The handling of tailings is also substantially facilitated, and the over-all capital cost of a large scale installation, as well as the operating and maintenance costs, can be expected to be hundreds of millions of dollars cheaper than an installation of the same capacity constructed in the conventional manner.

Abstract: ABSTRACT         In a document handling apparatus (10) for moving successive individual document sheets (23) on the imaging surface (37) of a movable vacuum belt (12) (60) into a copier imaging station (24), the vacuum belt (38)(67) has all its vacuum apertures (40)(70) limited to minor areas (38)(67) of the belt underlying the smallest document to be copied to avoid being exposed, but these apertures are pneumatically connected to a pattern of elongated airflow restrictive vacuum grooves (36)(76,77) which grooves extend unapertured under and beyond the document edge over a much greater area of the belt surface than the apertured areas.  These grooves provide document vacuum retention in the unaper-tured but grooved belt areas from vacuum apertures which open recessed in selected minor areas of the grooves, and with reduced airflow requirements.  The grooves have gently sloped walls (36a) and are otherwise designed to avoid reproducible shadows.  The grooves (36) are preferably pneumatically isolated from one another by ungrooved areas, and preferably extend across the belt transverse the direction of belt motion, to provide independent vacuum holding areas for capturing the lead edge areas of the document.  Preferably the aperture airflow area in each groove is several times the groove cross-sectional area so that the air pressure drop is along the groove under a document rather than in the apertures.  Preferably only defined minor areas ((38)(67, 68, 69) of the belt corresponding to the areas of overlying documents are grooved, which grooved areas are spaced along the belt between ungrooved (39) and the documents are registered over those grooved areas.  The vacuum manifold (18) surface (47) underly-ing the belt may also be grooved (48) for improved optical and pneumatic characteristics.

Abstract: ABSTRACT            Distortions during printing and laminating are minimized by printing the design on a stable base,  prefer-ably release paper, and then transferring the printed design to a hot plastic web made continuously by an extruder.  A stress relieved hot plastic film is then laminated to the printed web to provide a protective wear coat.  To emboss in register with the printed design the laminated product is first aligned by means of regis-tration marks that are printed along with the design. Embossing is then made using a conventional engraved roll having raised sections which are images of the printed design.  After embossing  the web is partially cooled and annealed.  It is then aligned with a die cutter using the same registration marks as used for alignment during embossing.  As a result, individual tiles can be cut automatically in register to the printed and embossed pattern.
