Patent CA-2300578-A1 (CA)
Inventor: COLEMAN JOHN G A
IPC: B07B1/50
Filed: 2000-03-10
Abstract: An apparatus for separating tobacco stem particles from a mixture containing such particles and tobacco stalk particles obtained in a threshing and separating process employed in a tobacco stemmery includes a hollow drum having a longitudinal axis, the hollow drum being mounted for rotational movement about its axis and the axis being disposed at a slight angle with respect to the horizontal so as to establish a higher inlet end and a lower outlet end of the hollow drum. A mixture handling structure is constructed and arranged with respect to the inlet end of the hollow drum to feed a supply of a mixture containing tobacco stein particles and tobacco stalk particles obtained in the threshing and separating process into the inlet end of the hollow drum.  The hollow drum has a periphery formed of a foraminus structure that includes a plurality of generally axially extending parallel bars spaced apart a distance sufficient to allow the passage of tobacco stem particles therethrough while substantially preventing the passage of tobacco stalk particles therethrough.  A power operated assembly rotates the hollow drum about its axis at a speed sufficient to cause a portion of the mixture entering the inlet end and falling on the lowermost bar which has not passed through the spaces between the bars to be carried through a cycle which includes an upward movement with the movement of the bars and a falling movement downwardly onto the lowermost bars at a position downstream and a repetition of the cycle until the remaining mixture is moved out the lower outlet end of the hollow drum. A tobacco stem handling structure below the hollow drum receives the tobacco stem particles passing through the spaces between the bars as the particles of the mixture are cycled within the rotating hallow drum and moves the tobacco stem particles away. A tobacco stalk particle handling structure at the outlet end of the hollow drum receives the remaining mixture moved out of the lower outlet end of the hollow drum and moves the remaining mixture away.

Title: A distributed stereo system
Inventor: ANDREWS LEONARD COLIN
IPC: H04R5/02
Filed: 1998-08-14
Abstract: This invention concerns a distributed stereo audio system (1). Distributed stereo audio systems are used to provide stereo sound to several rooms or areas from a single source of signal.  The system includes two or more speakers (2, 3) for the broadcast of stereo audio signals; a source of stereo audio signals; a stereo amplifier (4) to amplify stereo audio signals and drive the speakers; and a mains operated electrical power supply (10) to provide power to the amplifier. The amplifier is located in the same room as the speakers, and remote from the signal source and power supply. The amplifier is connected to the signal source and power supply by means of a category 5 four pair twisted cable (11) which provides, in respective twisted pairs, right channel audio signals (12) from the signal source to the amplifier, left channel audio (13) from the signal source to the amplifier, DC  power (14) from the power supply to the amplifier, and control signals (20) from the amplifier to the signal source.

IPC: H04N5/365
Filed: 1998-09-23
Abstract: The invention provides a sensor system (800) for generating a sensor signal (Sout) corresponding to a filtered image of a scene. The system (800) incorporates a multielement array (526) and associated processing circuits for providing element signals in response to images projected onto it and a projecting lens assembly (502) for projecting images onto the array (526). The lens assembly (502) projects differently blurred images of the scene onto the array (526) for generating a measurement signal during a measurement phase and a local spatial average correction signal during a calibration phase. A light-diffusing shutter (522) is used for generating the differently blurred images.  The system (800) substracts the measurement and correction signals of each element from one another to provide a difference signal and uses this signal to generate the sensor signal (Sout) during the measurement phase. The calibration phase is repeated on change of array temperature or incident radiation intensity, thereby reducing fixed pattern noise in the sensor signal (Sout) despite environmental change, and interrupting the measurement phase only infrequently.

Abstract: The invention relates to a regulating system for a gas burner. Regulating systems for gas burners are used for guiding a gas flow and a combustion air flow to the burner. The gas flow can be regulated depending on combustion air pressure. Pressure is measured in known regulating devices with the aid of a membrane, that is pneumatically. Said pneumatic pressure measurement limits the scope of application of known regulating devices. In the inventive regulating device, a sensor (16) is arranged between a first line (10) guiding a gas flow and a second line (12) guiding the combustion air flow, an electric or electronic signal (19) being generated by said sensor that is used to regulate the gas valve (11).

Title: Topical compositions comprising an opioid analgesic and an nmda antagonist
Inventor: KOLESNIKOV YURI
IPC: A61K31/245
Filed: 1999-07-15
Abstract: A topical opioid paradigm was developed to determine analgesic peripheral effects of morphine. Topical morphine as well as peptides such as [D-Ala2,MePhe4,Gly(ol)5]enkephalin (DAMGO) produced a potent, dose-dependent analgesia using the radiant heat tailflick assay.  The topical drugs potentiated systemic agents, similar to the previously established synergy between peripheral and central sites of action.  Local tolerance was rapidly produced by repeated daily topical exposure to morphine. Topical morphine tolerance was effectively blocked by the N-Methyl-D-Aspartate (NMDA) receptors antagonist MK801 and ketamine given either systemically or topically. NMDA receptor antagonists reversed pre-existing morphine tolerance. The activity of topical NMDA antagonists to block local morphine tolerance suggests that peripheral NMDA receptors mediate topical morphine tolerance. Morphine was cross tolerant to [D-Ala2,MePhe4,Gly(ol)5]enkephalin (DAMGO), but not to morphine-6,8-glucuronide, implying different mechanisms of action. These observations have great importance in the design and use of opioids clinically. Topical pharmaceutical compositions comprising an analgesic that functions through an opiate receptor and an NMDA receptor antagonist for producing analgesia without inducing tolerance are described.
