Title: Starch hydrolysates as sequesterers
Inventor: EASTMAN JAMES E
IPC: A23L27/00
Filed: 1994-02-07
Abstract: A starch hydrolysate composition is particularly suited for use as a sequesterer, i.e. it readily interacts noncovalently with other molecules to form stable inclusion complexes which are useful in a variety of applications. The starch molecules in the compostion which act as sequesterers are in the form of single helical inclusion complexes with starch molecules having a D.P. of about 10 to 200 and a weight-average D.P. of about 10 to 50 as the host molecule holding one or more guest molecules within their internal cavities. These hydrolysates are prepared by first converting amylopectin molecules from the double helix form to the single helix form and then by cleaving chain segments from the molecules. The sequesterers are principally useful in the agrichemical, food and pharmaceutical areas, as powderizers, stabilizers, reducers of volatility and toxicity, bioavailability enhancers and controlled release agents.

Patent CA-2156029-A1 (CA)
Title: Optical Switching Device
Inventor: SMILEY JOHN OMAR
IPC: G02B6/35
Filed: 1995-08-14
Abstract: An optical switch has a stepping motor with a fiber faceplate on which are mounted end portions of output optical fibers terminating in GRIN lenses. The end portions are arranged along a pitch circle. The faceplate is spaced from the stepping motor and the diameter of the pitch circle is smaller than the diameter of the stepping motor, the output fibers diverging from the faceplate towards the motor and beyond in a space-saving arrangement. The stepping motor drives a movable arm with attached end portion of an input optical fiber, also with a GRIN lens, into one of a plurality switching positions. The connection between the fibers and the lenses and also the relative axial arrangement of the paired lenses in the switching positions is offset to reduce or minimize the reflection of light transmitted from the input fiber to the output fiber, back to the input fiber.

Title: Method for controlling reaction temperature
Inventor: HUI CHI-WAI
IPC: C08F2/18
Filed: 1996-01-15
Abstract: A method for controlling reaction temperature for a reaction vessel used for conducting an exothermic reaction is disclosed which comprises employing two or more independent flow channels and feeding two or more coolants having different temperatures to the independent flow channels according to the quantity of heat to be removed.       By use of this method, not only energy-efficient coolant utilization and improved reaction control can be attained, but a high production efficiency and production flexibility can be achieved.       This method also has advantages, over the method for using coolant L throughout a reaction, that since the coolant is used only in the case of necessity, a small refrigerating apparatus is sufficient and a reduction in energy cost is attained.     This method is more effective when applied to a reaction vessel employing a temperature control element having a high efficiency of heat transfer.
