Filed: 1996-02-02
Abstract: The present invention relates to a method of producing an impregnated wooden product from a wooden article. The article is pressed isostatically with a pressure exceeding 1,000 bars in a first method step. The wooden article is then placed in a bath containing a liquid-impregnating agent in a second method step and allowed to swell so that at least a part of the impregnating agent is absorbed by the article. The method may optionally be supplemented with a third method step in which the article is pressed isostatically with a pressure exceeding 1,000 bars, so as to form a hard element. The third method step may alternatively be applied to a conventionally pressure-impregnated article.

Patent CA-2232219-A1 (CA)
Inventor: ANDERSON JOHN ERLING
IPC: C21C5/46
Filed: 1998-03-16
Abstract: A method for effectively providing main gas into a pool of molten metal, which is particularly useful for use in an electric arc furnace. The method employs combustion of secondary oxygen with fuel to form a flame envelope around a main gas stream which protects the main gas from entrainment of ambient gases as it passes through the headspace of the furnace. This enables the gas to retain to a substantial degree its original force upon injection into the headspace and thus may be injected into the furnace at a safe distance from the molten metal surface while still achieving substantially complete penetration into the molten metal.

Inventor: HUMPLEMAN RICHARD
IPC: H04M3/00
Filed: 1996-11-21
Abstract: A home network architecture has an internal digital network interconnecting devices in the home. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to the internal network. The network interface units are selectively directly connected by a direct circuit crossbar to set-top electronics so that video data, for example, may be directly provided from a network interface unit to the set-top electronics without jitter. A passive hub, which does not have packet routing capability, is then used to provide signal regeneration and re-transmission of other data over the network.

IPC: B65G61/00
Filed: 1998-06-03
Abstract: A method for removing and transporting ophthalmic lens fabricating mold sections from a molding device to an inert chamber in a predetermined time, controlled by a central processor, is disclosed.      The method includes starting a timer upon opening the molding device and exposing the mold sections; actuating a robotic arm to transport the mold sections from the molding device to an intermediate position using a compound movement; actuating a cam-controlled arm to transport the mold sections from the intermediate position to a palled held on a conveyor belt at a cam-arm pre-part release location; and releasing the pallet to move.on the conveyor belt to the inert chamber for continued transport of mold containing pallets to a treatment or processing facility for producing and/or packaging of the contact lenses. The method also includes raising a nest to receive the mold sections at the intermediate position; and lowering the nest, after transfer thereon of the molded sections from the robotic arm, for transferring the molded sections to the cam-controlled arm. In a racetrack mode, the pallets continue moving into the inert chamber, while the molded sections are discarded.

Filed: 1996-09-10
Abstract: This invention is an improved tongue depressor (10) that has a flat elongated blade (12) having a first end (14) and a second end (16). To the first end (14) is integrally attached a first tongue contact section (34), and to the second end (16) is integrally attached a second tongue contact section (70).  Each of the tongue contact sections has a lower surface (42) that includes sequentially a downward slope (44, 80), a flat horizontal surface (48, 84), and an upper slope (52, 88). The downward slope and the flat horizontal surface interface with the tongue and preferably have a non-slip surface (60).  At the center, and lower horizontal surface (20) of the elongated blade (12) is located a reinforcing protrusion (28) that prevents the tongue depressor from bending or breaking in the middle. Because the size of an adult mouth is generally larger than a child's mouth, one of the tongue contact sections is made with a smaller width.
