Patent CA-2169008-A1 (CA)
Title: Seed coating apparatus
Inventor: MEMORY RUSSELL J
IPC: A01C1/06
Filed: 1996-02-07
Abstract: A seed treating device is mounted on a seeding implement to treat untreated seeds carried by the implement with inoculants or other treating material before the seeds are planted into the ground. The implement conveys seeds in a flow of air carried by conduits to entrain the seeds within the air flow. The seed treating unit is placed on the implement remote from the storage tank for the seeds to receive airborne seeds from an inlet tube, treat the seeds with a coating material, and discharge the seeds through an outlet tube to planting mechanisms. The seed treating unit includes a conical mixing chamber to induce the air/seed flow into a whirling motion where the coating material is introduced for an even coating of the individual seed particles. The inlet line is oriented generally tangential to the circular mixing chamber, while the outlet line is generally perpendicular to the inlet line and is centrally connected to the main axis of the mixing chamber.

Patent CA-2176452-A1 (CA)
Inventor: ZHONG QIMING
IPC: C01B32/00
Filed: 1996-05-13
Abstract: The surface area of carbonaceous powders can be reduced by mixing a small amount of petroleum or coal tar pitch with the carbonaceous powder and pyrolyzing the mixture. The carbonaceous powder becomes coated with decomposition products of the pitch and the coating can have substantially lower surface area than the original carbonaceous powder. Small amounts of pyrolyzed pitch are involved and the bulk properties of the carbonaceous powder remain virtually unaffected. The method is particularly suitable for reducing the surface area of carbonaceous anode powders for use in non-aqueous rechargeable lithium ion batteries and thereby improves the safety of the batteries.

Abstract: An amorphous carbon material, especially for an electrode of a lithium ion secondary battery, is characterized by an interlayer spacing d(002), obtained from the X-ray diffraction line assigned to the (002) plane of the carbon, of 0.345 nm to 0.365 nm, a ratio (Ps) os the number of carbon atoms involved in the layer structure to the total number of carbon atoms of from 0.54 to 0.85, and a ratio of the total nitrogen:total carbon atoms in the amorphous carbon of 0.005;1 to 0.055:1. The amorphous carbon material is prepared by applying a heat treatment to an amorphous carbon under under vacuum or inert gas atmosphere for at least 30 minutes to provide the desired crystalline structure. The carbon material may take the form of carbon fiber material, especially short carbon fibers obtained by pulverising larger carbon fibers.  A lithium ion secondary battery containing an electrode comprising such an amorphous carbon material has a large discharge capacity and high charge-discharge cycle characteristics.

IPC: E01C5/08
Filed: 1996-08-09
Abstract: The existing pavements - the flexible structures which carry all traffic dynamicand static loads, are in direct contact and are directly supported by the flexible subgrade and depend of its quality and performance, follow its deflections and differential settlements due to directly transferred traffic loads,crack and deteriorate, allowing the water penetration through the cracks into the subgrade layer. In winter/spring season the frost and thaw action form the ice lenses below the pavement surface and, by thawing action increase their volume lifting up the pavement, increase the cracks and form the potholes, having as a result ,the very costly yearly repairs . My invention is a New Construction for Highways, Roads and Streets, made of structural concrete elements interlocked into a solide, monolithic tunnel type frame unit. The pavement is now a structural concrete element, separated from the subgrade by an airspace of at least ten (10) inches ,to prevent any contact between them and is designed to support all traffic static and dynamic loads and transfers them through its lateral supports-reinforced concrete walls and their foundation to the supporting soil below the frost penetration line as uniformly distributed load.

Title: Dry ice expanded tobacco
Inventor: CUMNER CLIVE STEWART
IPC: A24B3/18
Filed: 1995-01-19
Abstract: In a process for expanding tobacco, an equilibrium pressure within a process vessel (1) containing a mixture of gaseous carbon dioxide and liquid carbon dioxide is selected before charging a sample volume of tobacco from a batch of tobacco into a sealable impregnator vessel (2). Liquid carbon dioxide is then transferred at the selected equilibrium pressure from the process vessel (1) into the impregnator vessel (2) where it is maintained sufficiently long to permit liquefied carbon dioxide to penetrate the cells of the tobacco. Liquid carbon dioxide is subsequently transferred from the impregnator vessel (2) into a drain vessel (3) and the pressure within the impregnator vessel (2) is reduced sufficiently to cause the solidification of liquid carbon dioxide contained within the cells of the tobacco. Finally, the tobacco is heated sufficiently to vaporise the carbon dioxide in the tobacco cells thereby expanding the tobacco. The degree of tobacco expansion obtained is determined and the equilibrium pressure within the process vessel (1) is re-selected to control the amount of solid carbon dioxide formed during the de-pressurisation step of a subsequent impregnation cycle or cycles to optimise the degree of expansion of tobacco for the remainder of the batch.
Patent CA-2181822-A1 (CA)
Title: Rechargeable positive electrode
Inventor: CHU MAY-YING
IPC: H01M4/62
Filed: 1995-10-03
Abstract: Disclosed are methods of making solid-phase active-sulfur based composite electrodes. The method begins with a step of combining the electrode components (including an electrochemically active material, an electronic conductor, and an ionic conductor) in a slurry. Next the slurry is homogenized such that the electrode components are well mixed and free of agglomerates. Very soon thereafter, before the electrode components have settled or separated to any significant degree, the slurry is coated on a substrate to form a thin film. Finally, the coated film is dried to form the electrode in such a manner that the electrode components do not significantly redistribute.

IPC: G01M3/04
Filed: 1995-04-06
Abstract: A method of introducing a leak detection additive (48) into a closed refrigeration system (10) by a substrate containing the additive (48). A  predetermined amount of the additive (48) is implanted on and absorbed into a host swatch (52) of substrate material which is capable of absorbing and releasing the leak detection additive (48), but which does not react with refrigerant or system lubricant. The swatch (52) is installed in a desiccant bag (40), which is then installed in a dehydrator (30) of the refrigeration system (10). The refrigeration system (10) is assembled, charged and operated, by which the refrigerant and system lubricant flowing through the desiccant bag (40) mixes the additive (48) with the refrigerant and system lubricant. In alternative embodiments, the substrate is constructed to be used as a filter in various components of the refrigeration system.
