Granted: 2009-03-10
Abstract: A process is disclosed for recovering raw materials, in particular heavy metals such as chromium, by separation from waste and residues, wherein a liquid or viscous starting mixture and/or a starting mixture composed of crushed or ground components is first prepared. The invention is characterised in that the raw materials are separated by a thermochemical treatment. The liquid, viscous and/or solid starting mixture is first mixed with additives, depending on its composition, then subjected to a thermal treatment in an oven The atmosphere in the oven flows through the starting mixture and the suspended materials thus generated as flakes or dust are conveyed out of the oven through a filter installation with several stages in which they are separated from t he waste gas. The first filter is designed as a hot filter, after which the waste gas is cooled and after flowing through at least a second filter, pre-heated and then burnt at a high temperature.

Abstract: A method for producing a chewing gum, as well as the chewing gum so produced, incorporates a physiological cooling agent, such as acyclic carboxamide, or combinations of physiological cooling agents. In another embodiment a combination of physiological cooling agents is made in a modified release structure. The modified release/cooling agents combination is preferably obtained by physically modifying the properties of the combination of cooling agents by coating and drying. When incorporated into gum, these particles are adapted to enhance the shelf stability of the flavor and/or produce a modified release when the gum is chewed. In another embodiment, the physiological cooling agent is present with menthol and menthone. In another embodiment, coated chewing gum has a coating that comprises a physiological cooling agent. The preferred inventive chewing gum provides a high flavor impact in which the harsh notes normally associated with such a high flavor impact have been reduced or eliminated. In addition, the preferred inventive gum provides a clean, high-quality, cooling chewing gum coating with xylitol or other polyols where xylitol has been reduced in concentration or eliminated.
Patent CA-2307240-C (CA)
Inventor: MA STANELY JEH-CHUN
IPC: G01R19/155
Filed: 2000-05-01
Granted: 2011-04-12
Abstract: A matchline sense circuit for detecting a rising voltage on a matchline of a CAM array is disclosed. The circuit initially precharges a matchline to ground before turning on a current source to supply current to the matchline and raise the voltage of the matchline. A reference matchline sense circuit generates a self-timed control signal to keep the current supply turned on for a predetermined duration of time. Sensed data on the matchlines are latched after the current source is turned off and the matchlines are precharged to ground. Because the matchline sense circuit of the present invention precharges the matchlines to ground instead of the supply voltage, VDD, less power is consumed. By sensing the rise of the matchline voltage to an n-channel transistor threshold potential, the matchline sensing operation speed is increased.

Granted: 2008-10-28
Abstract: An interbody osteogenic fusion device (10) is provided that includes opposite end pieces (11, 12) with an integral central element (13). The end pieces (11, 12) are sized to maintain the height of an intervertebral disc space (S). The central element (13) has a much smaller diameter (D2) so that the osteogenic fusion device (10) forms an annular pocket (24) around the central element (13). An osteogenic material (30) is disposed within the annular pocket (24) between the opposite end pieces (11, 12). In one embodiment, the osteogenic material (30) constitutes a coIlagen sheet (30) soaked in a solution containing a bone morphogenetic protein (BMP). The osteogenic fusion device (10) is configured so that the osteogenic material (30) is in direct contact with the adjacent vertebral bone (V1, V2). In addition to the enhanced area of contact between the vertebral bone (V1, V2) and the fusion material (30), the inventive osteogenic fusion device (10) reduces stress-shielding and minimizes the radiopacity of the implant so that growth of the fusion mass can be continuously assessed. In yet another embodiment, the osteogenic fusion device (10) includes at least one end piece (12) with a truncated surface (21). The osteogenic fusion devices of the present invention may be combined with other fusion devices to form an implant system. The implant system (140) includes at least one load bearing member (110) having a truncated surface (116) configured to nest within another load bearing member, preferably the load bearing, osteogenic fusion device (10) of the present invention. The invention also provides implant systems (210) comprising adjacent load bearing members (211, 212) connected to one another to resist lateral separation. Methods of promoting fusion bone growth in the space (S) between adjacent vertebrae (V1, V2) utilizing devices and systems of the invention are also described.
