Abstract: A paper cutting device provided in a facsimile machine, copier, printer, or the like for cutting paper discharged from a roll at a predetermined length. The paper cutting device includes a stationary cutter (2), a movable cutter (5) and movable carriage (3) to which the movable cutter is secured and which is movable along the stationary cutter (2) so that the stationary cutter in cooperation with the movable cutter cut the paper.      The stationary cutter (2) extends in the lateral direction of the paper which is supplied to the paper cutting device.      The carriage (3) includes a front plow portion (33a) far guiding the paper to a cutting position where the stationary cutter (2) and the movable cutter (5) overlap. When the carriage (3) traverses to cut the paper, the paper is urged toward the cutting position by the front plow portion and is cut. Thereafter, the cut portion of the paper is separated from the carriage 3 at a curved concave portion 33d of the carriage.

Abstract: In general, conventional gabions include metal baskets filled with rocks.  These structures have several drawbacks including the susceptibility to destruction of the baskets under ice exposure conditions.  Other systems include concrete slabs with horizontal tie backs or vertical concrete slabs hinged between poles or columns attached to a basket formed of synthetic material filled with rocks.   The drawbacks of these systems include the requirement for labour intensive earthwork and heavy compacting equipment, and the expensive components.  A simple gabion which avoids the above problems includes a lightweight, polymeric concrete panel and a basket defined by a flexible mesh sheet, at least the ends of which are embedded in and retained by the panel for reinforcing the panel, the sheet extending from the end of the panel and defining a closed loop with the panel for receiving fill, whereby similar baskets can be stacked on each other to form a retaining wall.  The polymeric concrete mixture used in the gabion (and for other uses) includes approximately 16.9 to 24.04 weight percent portland cement, approximately 59.0 to 72.1 weight percent expanded shale or clay, approximately 5.5 to 13.0 weight percent water, approximately 3.3 to 7.4 weight percent polymer, and approximately 0.21 to 0.32 weight percent superplasticizer.

Title: System for the secure transportation of articles
Inventor: CASSIDY GERALD ANTHONY
IPC: G07D11/00
Filed: 1994-07-18
Granted: 1999-08-10
Abstract: A system for the secure transportation of articles such as cheques and bank notes comprises first and second docking stations at different locations, and a secure container which mates with the docking stations. The container has a number of lockable doors into which bank notes are fed by a feeder mechanism at the first docking station. The container has its own microcontroller which monitors the status of the doors and the integrity of the container, and which can respond to external control signals while it is in transit. Once the container has been loaded at one docking station, it is transported to the second docking station at a different location, where it can be unloaded. A one-time code is generated each time the container is loaded, and must be communicated to the second docking station before the container can be unloaded. Any attempt to tamper with the container while it is in transit results in the activation of a dye dispenser, which marks the contents of the container.

Granted: 2005-02-08
Abstract: Flaky pie shells that maintain their structural integrity even when filled with high moisture fillings contain fats bearing short C2 to C4 acid residues and long, saturated C16 to C22 fatty acid residues. One preferred embodiment contains fats beating butyric acid residues and residues of fatty acids derived from fully hydrogenated oils containing at least about 75% stearic acid such as hydrogenated soybean oil or hydrogenated canola. Another preferred embodiment contains fats bearing the same complement of saturated long residues, but the short residues are derived from acetic and propionic acids. These fats are low in calories and low in palmitic acid and trans unsaturated acid residues. Pie shells made with the fats are tender and exhibit improved cohesiveness and mechanical strength daring shipping, handling and storage.

Abstract: Disclosed is a method for making dry coffee aroma gas with improved aroma characteristics, A stream of moisture-containing coffee aroma gas is passed through and allowed to exit a desiccant bed of calcium sulfate granules, wherein said granules initially contain less than about 0.5 % adsorbed moisture by dry weight of said granules. The stream of moisture-containing coffee aroma gas is discontinued after the adsorbed moisture content of the calcium sulfate granules increases from less than about 0.5 % to at least about 4.3 % by dry weight of said granules, but before the moisture content of the stream of desiccant-treated coffee aroma gas exiting the desiccant bed exceeds about 1000 ppm. All of the desiccant-treated coffee aroma gas which exits the desiccant bed is collected and combined until the stream of moisture-containing coffee aroma gas is dicontinued. The desiccant-treated coffee aroma gas contains between about 10 and about 200 ppm of moisture and does not exhibit an unbalanced and excessively musty aroma. The dessicant-treated coffee aroma gas can be used to aromatize food substrates, e.g., instant coffee.
