Patent CA-2492179-A1 (CA)
Inventor: MAIER GERHARD
IPC: B29C67/00
Filed: 2003-06-27
Abstract: The invention relates to combinations of a material and a bath fluid for a method for directly printing visual-aid models or components, especially for using in the office or at home. The invention also relates to the polymers obtained from the reaction of the material and the bath fluid, and the components or models produced from the inventive combinations. The use of the inventive combinations in rapid prototyping methods enables the production of components with varying mechanical properties. Coloured components can be obtained by adding dyes. The components consisting of the inventive materials have mechanical properties and thermostability and are produced with precision, thus rendering them suitable as visual-aid models and discussion models for design, architectural, constructional and other blueprints. The surface quality, the rigidity and the hardness of the components can be improved by post-treatment.

IPC: H02H1/00
Filed: 2005-01-12
Abstract: A shorting system, which eliminates persistent arcing faults in power distribution equipment, includes a first shorting switch having separable contacts, an actuation input and a fuse electrically connected in series with those contacts. A second shorting switch includes an actuation input and separable contacts, which are electrically connected in parallel with the series combination of the fuse and the first shorting switch contacts. A detection circuit includes one or more arcing light sensors and an actuation circuit. The light sensors detect arcing fault light and the actuation circuit responsively outputs a first trigger signal to the first shorting switch actuation input to close its contacts. For a persistent arcing fault, which is not eliminated by the first shorting switch, a predetermined time after the first trigger signal, the actuation circuit responsively outputs a second trigger signal to the second shorting switch actuation input to close its contacts.

Title: Preparation for fixing to a natural piece of tooth or to a tooth and corresponding fixing method
Inventor: TORRIANI LAURENT
IPC: A61K6/884
Filed: 2003-08-15
Abstract: A preparation for being fixed to a natural tooth part has surface regions consisting of a material with thermoplastic properties. The preparation has oscillation properties with damping losses that are so small that local stress concentrations are required for liquefying the material by oscillation, the preparation being designed such that the stress concentrations only occur in the region of the preparation surface. The preparation is positioned on a suitably prepared natural tooth part such that the material with the thermoplastic properties is in contact or may be brought into contact with the dentin surface and/or enamel surface. The preparation is then made to mechanically oscillate and is simultaneously pressed against the natural tooth part, whereby the material with the thermoplastic properties is at least partly liquefied and brought into intimate contact with the dentin or enamel surface such that, after solidification, it forms a positive fit and/or material fit connection.

Title: Telecommunications interface
Inventor: HENDERSON RICHARD E
IPC: H04Q11/04
Filed: 2003-09-12
Abstract: A Digital Subscriber Line (DSL) transport can be extended economically by a retrofit cabinet (132) which can replace a standard telephone cross~connect cabinet or by placement of a new cross-connect cabinet. The retrofit cabinet (132) or new cabinet incorporates within it a Digital Subscriber Line Access Multiplexer (DSLAM)(174). The inclusion of the DSLAM (174) in the same cabin et with the cross-connect blocks avoids problems associated with real estate acquisition and approvals, avoids problems resulting from crosstalk, and avoids the necessity of replacing older feeder cabling that is incapable of carrying DSL signals. With pre-wired connections between the cross-connect blocks and the DSLAM electronics, it is possible to provide DSL transport to a subscriber by cross-connecting readily accessible terminals within the cabin et (132). The retrofit cabinet may also have additional feeder (158,160) and distribution (162,164) connection blocks for expansion of telephone service as well as DSL transports to new subscribers.

Title: Heart rate monitor for controlling entertainment devices
Inventor: VOLPE JOSEPH C JR
IPC: A63B69/00
Filed: 2003-04-23
Abstract: Described is a motivational fitness device, which controls volume and power on a television or stereo component in response to the heart rate. The user mus t exercise in their specific heart rate target training range to keep their entertainment device turned on at an enjoyable volume. A heart rate sensing device relays heart rate to a remote control unit. The control unit receives and compares the user~s heart rate to the specified target range and sends infrared remote control signals (or not) to the entertainment device. If the user~s heart rate drops below the target range, the volume of their entertainment device will gradually decrease and ultimately switch off until the user reacquires their target. Conversely, if the user is exercising too vigorously, the volume will increase, motivating the user to reacquire their target heart rate range. This device requires no exercise equipment, yet any type may be used with it.

Title: Apparatus for producing seedlings and method of producing seedlings
Inventor: OKABE KATSUYOSHI
IPC: A01G7/04
Filed: 2004-06-14
Abstract: It is intended to provide an apparatus for nursing seedlings and a method therefor whereby, in nursing grafted fruit vegetable seedlings, a process from breeding of nursery plants (stocks and scions) to post-grafting care can be consistently carried out at a low cost. Stocks and scions are nursed on a plural number of nursing shelves 3 located in a closed construct surrounded by light-shielding and heat-insulating walls. Then these stocks and scions are bonded to each other to give grafted seedlings 8. Next, these grafted seedlings 8 are placed on a plate 3a of the nursing shelves and coated with a light-permeable cover 9 having vent holes 15. Then the grafted seedlings 8 are irradiated with a fluorescent lamp 5 at a definite light intensity through the light-permeable cover for post-grafting care. Immediately after the grafting, the relative humidity in the light-permeable cover is elevated due to water evaporation from the stocks and scions and thus the take of the scions to the stocks is promoted. When the plants vigorously carry out photosynthesis, gas exchange arises between the carbon dioxide gas-containing atmosphere in the closed construct and the atmosphere within the light-permeable cover through the vent holes, thereby replenishing carbon dioxide gas inside the light-permeable cover.
