IPC: C07C67/03
Filed: 2002-11-22
Abstract: The invention relates to a method for obtaining a 5-bromolaevulinic acid methyl ester (or a 5-chlorolaevulinic acid methyl ester) from a bromination mixture (or a chlorination mixture) containing a 5-bromolaevulinic acid methyl ester (or a 5-chlorolaevulinic acid methyl ester) and produced by means of bromination (or chlorination) of laevulinic acid or a laevulinic acid methyl ester. The inventive method comprises the following steps: a) said bromination mixture (or chlorination mixture) is dissolved in an organic solvent or solvent mixture; b) the solution is cooled to a low temperature, preferably to a temperature which is lower than -20 ~C, especially in the temperature range between -20 ~C to -40 ~C; c) the 5-bromolaevulinic acid methyl ester (or 5-chlorolaevulinic acid methyl ester) is crystallised out of the solution; and d) the crystalline 5-bromolaevulinic acid methyl ester (or 5-chlorolaevulinic acid methyl ester) is isolated by draining off the solution with the remaining bromination mixture (or chlorination mixture).

Patent CA-2488353-A1 (CA)
Title: Self-braking ball clutch (sbbc) and ball feeding drive
Inventor: VEINBERG LEONID S
IPC: B21D43/00
Filed: 2004-11-25
Abstract: SBBC is a device that allows to move/feed a rod ONLY in one direction. This one directional feed is made possible by the balls housed between the conical base surface of the housing, that has a reverse angle smaller than the braking angle, and a rod surface. With this design, the balls do not restrict the rod movement in the angle opening direction. However, if the rod were to be moved in the opposite direction, the balls would be wedged between the conical base surface of the housing and the rod surface, thus completely restricting the rod movement. The principle of the self-braking lock is the basic idea for the ball feeding type designs, ball catchers in safety systems, lifting and transportation mechanisms, as well as for easy length adjustable link.

Title: Fuel system for premix burner of a direct-fired steam generator
Inventor: HARDEN PHILIP ALAN
IPC: F23N5/20
Filed: 2005-04-25
Abstract: A direct-fired, propane powered steam generator is provided with a carburetor, which receives vaporized propane from a converter arrangement which converts liquid propane to vapor, receives pressurized air and feeds a mixture of vaporized propane and air into the combustion chamber of the steam generator.  The amount of air delivered to the carburetor is variable, with the amount of vaporized propane entering the carburetor being determined by the position of a metering valve which varies in accordance with the amount of air passing through the carburetor. The converter arrangement receives liquid propane and is coupled to process water heated in the water jackets of the combustion chamber and adjacent structure, the converter arrangement being designed so that heat from the water is transferred for effecting vaporization of the liquid propane. The flow of liquid propane for combustion in a pilot burner and for combustion in the main combustion chamber may be controlled using various arrangements of solenoid-operated lock off valves and/or vacuum-operated fuel lock off filters and/or air pressure balance control valves.
