Title: Automated tape splicing system
Inventor: CAIRNS JOHN
IPC: B65H19/18
Filed: 1998-01-21
Abstract: A multi-roll automatic tape splicing device includes a platen which is rotatablymounted on a support frame via a shaft. Two or more tape mandrels are rotatably disposed on the platen at a substantially equal distance from the shaft, and substantially equally spaced from each other, each mandrel being capable of receiving a respective roll of tape. An index drive is operatively coupled to the platen, for selectively rotating the platen so as to successively move each mandrel into a predetermined operating position at which a web of tape can be drawn from a respective roll of tape disposed on the mandrel, and for moving a mandrel out of the operating position when the respective roll of tape is depleted. A first sensor is operatively mounted on the support frame and capable of detecting a depleted condition of a roll of tape mounted on a respective mandrel in the operating position. A second sensor is operatively mounted on the support frame and capable of detecting rotation of a mandrel in the operating position. A cutting unit is disposed on the frame and capable of severing a web of tape being drawn from a depleted roll of tape. A control unit is responsive to the first and second sensors such that when the first sensor detects a depleted condition of a roll of tape, the control unit controls the index drive to rotate the platen and thereby move the next successive mandrel into the operation position. A tab formed on the end of a fresh roll of tape mounted on the successive mandrel adheres to the web of tape being drawn from the depleted roll, thereby causing a web of tape to be drawn from the fresh roll. Thereafter, the control unit controls the cutting unit to cut the web of tape being drawn from the depleted roll, when the second sensor detects rotation of the mandrel in the operation position. 12

Patent CA-2229493-A1 (CA)
Inventor: MCNABB ANDREW J
IPC: C09K3/22
Filed: 1998-03-13
Abstract: Disclosed is a substantially dust free solid like ammonium sulfate that is treated with a blend of water or solvents and distillation bottoms. The distillation bottoms are liquid at about 60°C or less and are obtained from production of an alcohol having the formula:     wherein R1 is substituted or unsubstituted, branched, straight chain, or cyclic C4 to C12 and R2 is OH or H.          The application of such distillation bottoms to the solid hinders the tendency of this solid to generate dust.          Thus the resulting solid materials are substantially dust-free, which make them particularly useful in the solids handling industry, especially in the granular fertilizer field.          Aslo disclosed are treated solids that are in the form of unpaved thoroughfares such as gravel parking lots and dirt roads.

Title: Fuel cell with improved water-removal system
Inventor: MERGEL JUERGEN
IPC: H01M8/04119
Filed: 1996-08-22
Abstract: The aim of the invention is to provide a fuel cell from which the water produced can be easily removed and for which external wetting is not necessary. The water or water-containing vapour originating in the fuel cell is passed into a water separator where it is condensed. The water separator (2) has a control device in the form of a valve (6) which automatically empties it. A commercially available water separator can be used, with a float valve which opens as soon as enough condensate water is present. Also fitted is a control device designed to control the water or water-vapour outlet. This device is located either in front of or behind the water separator. An inexpensive needle valve has been found to be suitable for use as this device, which can be automated and gives a controlled output flow of water or watervapour/gas mixture. Oxygen losses can thus be minimized to the extent that they become negligible.

Abstract: A heat exchange catalytic process and reactor of the shell-and-tube type having a plurality of tubes extending longitudinally through the shell from a tube fluid inlet region to a tube fluid outlet region and baffles extending transversely across the shell dividing the shell between said inlet and outlet regions into at least three heat exchange zones through which each tube passes in sequence in heat exchange with that zone. A shell fluid is passed through the heat exchange zones in heat exchange with the tube fluid passing through the tubes. Transfer passages are provided connencting the heat exchange zones and are disposed so that the shell fluid passes through the second zone before or after it has passed through both the first and third zones. A particulate catalyst is disposed in either the shell heat exchange zones or, preferably, the tubes. The process utilises a heat exchange medium, particularly water, that does not change state under the prevailing conditions and is preferably fed to the shell heat exchange zones while the reactant stream passes through the catalyst disposed in the tubes. The process is particularly applicable to the selective hydrogenation of acetylenes in the presence of olefins.
