Title: Veneer heating apparatus
Inventor: HONDA NORIYUKI
IPC: F26B7/00
Filed: 1997-04-16
Abstract: A veneer drying apparatus comprises a pair of upper and lower hot plates connected to a heating unit and a plurality of steam escape grooves formed in the opposing press surfaces of the upper and lower hot plates. The apparatus further comprises intermittently driven endless belts and driving and driven rollers on the unloading and loading ends, respectively, of the lower hot plate. The endless belts are trained over the driving and driven rollers for transferring veneer P over the upper surface of the lower hot plate. Each endless belt has numerous apertures formed in the entire surface thereof in a regular pattern. The driving rollers have numerous protrusions formed on the periphery thereof for engaging in the apertures formed in the endless belts. The endless belts are smoothly driven by rotation of the driving rollers due to the protrusion-aperture engagement.      Not driven by friction, the endless belts can be relatively thin, so that the entire apparatus can be simplified and made smaller while achieving improved transfer of heat from the belt to veneer P and permitting easy belt replacement.

Title: Convection rethermalization system
Inventor: WESTBROOKS JOHN W JR
IPC: A47J39/00
Filed: 1997-06-11
Abstract: An integrated refrigeration and rethermalization system includes a wall unit having a refrigeration system for producing refrigerated air and a convection heating system for producing heated air.  A cart having hot and cold compartments for storing food items on trays is docked with the wall unit to receive refrigerated and heated air.  A thermal barrier isolated the hot and cold compartments of the cart.  The thermal barrier includes a plurality of thermal dividers filled with an insulating foam material.  Each tray contains both hot and cold items and is positioned in the cart so that hot food items are located within the hot compartment and cold food items are located within the cold compartment.  Movable damper doors within the wall unit control the flow of refrigerated and heated air from the wall unit to the cart.  When the cart is docked with  the wall unit, foods within both compartments are initially stored in a refrigerated state.  At a desired serving time, the damper doors are moved to enable air to flow from the wall unit into the hot compartment while refrigerated air flow is maintained in the cold compartment.  If needed, the rethermalization cycle can be extended by a manually activated boost cycle.  After rethermalization is completed, the cart is undocked and transported to a food service area where the meals are served.

Patent CA-2219342-A1 (CA)
Inventor: RAAD ISSAM
IPC: A61F2/06
Filed: 1996-04-22
Abstract: A non-metallic antimicrobial impregnated medical implant, such as a catheter, and a method for impregnating a non-metallic medical implant with an antimicrobial agent is provided. The method for making the impregnated implant comprises the steps of forming an antimicrobial composition of an effective concentration to inhibit the growth of organisms, such as staphylococci, other gram-positive bacteria, gram-negative bacilli and Candida and applying the antimicrobial composition to at least a portion of the medical implant under conditions where the antimicrobial composition permeates the material of the medical implant. The antimicrobial composition is formed by dissolving an antimicrobial agent in an organic solvent, adding a penetrating agent to the composition, and adding an alkalinizing agent to the composition. The antimicrobial composition is preferably heated to a temperature between about 30 ~C and 70 ~C prior to applying the composition to the medical implant to enhance the adherence of the antimicrobial agent to the medical implant material. After the impregnated implant is removed from the antimicrobial solution, the impregnated implant is allowed to dry, then rinsed with a liquid and milked to remove excess granular deposits and ensure uniform color of the impregnated implant.

Patent CA-2233788-A1 (CA)
Inventor: WANG SHAOYING
IPC: A01G27/06
Filed: 1998-06-02
Abstract: Hand watering of plants and spray irrigation systems (tube watering, spray tube watering, and perimeter watering systems) commonly used in greenhouses not only lead to enormous water waste, fertiliser leaching and unnecessary new growth through over watering, but may also cause flower wilt through under watering. The watering time and amount are not decided by the requirements of plant growth and therefore may not be suited to plant growth. Many scientific experiments on the water requirements of plants do not produce significant results due to difficulties in controlling the water content of the soil. It is important to invent an apparatus to solve this problem. In order to supply an optimal amount of water to flowers and plants at proper times, according to their needs, three elements are essential. First, an indicator is needed which can reflect the water content (soil suction: equivalent to negative pressure) in soil that produces optimal plant growth. Second, an available and controllable water storage source is required. Third, a water transfer system is needed to connect the soil and water storage source. The WSP is comprised of a double walled pot that is used for water storage source. A porous ceramic column is used as an indicator to reflect soil suction (negative pressure) related to plant water requirements and to control water transfer to the soil. Porous ceramic cups are used as a water passage and pressure transfer system that connects the water storage compartment and the soil. The WSP supplies water to the soil through the porous ceramic cups under control of the indicator. Water is supplied when the plant requires water. The supplied water is equal to the amount demanded for optimal plant growth. Therefore, water waste and fertiliser leaching does not occur. This product has great time saving potential for greenhouse work and in the home. Furthermore, it can be used for research activities related to transpiration and drought tolerance of plants at different soil water levels.

Abstract: Dans un réseau de télécommunications par satellite, des ensembles locaux de voies disponibles sont attribués à chaque station terrestre au sol GES par une station de gestion de canaux de réseau NCMS, qui enregistre un ensemble de voies non attribuées. Si le nombre de voies inutilisées dans un ensemble local passe en dessous d'un niveau prédéterminé, des voies supplémentaires, extraites d'un ensemble régional dans la station de gestion de canaux de réseau NCMS, sont attribuées. Si le nombre de voies dans un ensemble local est supérieur à un niveau prédéterminé, les voies en surplus sont placées dans l'ensemble régional, ce qui fait qu'elles peuvent être attribuées à des ensembles locaux dans d'autres stations terrestres au sol GES.
