Patent CA-2045624-A1 (CA)
Inventor: ROSENBLATT AARON A
IPC: C01B11/10
Filed: 1990-09-17
Abstract: A method and apparatus for the generation use, and disposal of chlorine dioxide is disclosed. A solid sodium chlorite composition having impurities, at least one of which is sodium hydroxide, is contacted with an agent to consume essentially all of the sodium hydroxide. Chlorine dioxide gas is then generated by contacting t he resultant composition with chlorine in a humidified inert carrier gas. The resultant chlorine dioxide gas mixture may then be treated to remove chlorine gas present therein by contacting the same with soda-lime in particulate form. After using the chlorine dioxide gas mixture in the desired manner, chlorine dioxide present in the spent effluent gas may be substantially removed via t he introduction of the effluent gas into an aqueous solution of sodium thiosulfate having a sufficient amount of an inorganic ba se to maintain the alkalinity of the solution during consumption of thiosulfate by chlorine dioxide.

Title: Method of producing thermoplastic elastomers having alternate crystalline structure such as polyoxetane aba or star block copolymers by a block linking process
Inventor: WARDLE ROBERT B
IPC: C08G18/28
Filed: 1991-08-12
Abstract: A method of preparing a thermoplastic elastomer having A blocks and at least one B block, wherein said A blocks are crystalline at temperatures below about 60°C and said B block is amorphous at temperatures above about -20°C, said A blocks each being polyethers derived from monomers of oxetane and its derivatives and/or tetrahydrofuran and its derivatives, the method comprising: providing monofunctional hydroxyl terminated A blocks which are crystalline at temperatures below about 60°C and separately providing di-, tri- or tetrafunctional hydroxyl terminated B blocks which are amorphous at temperatures above about -20°C, end-capping said A blocks by separately reacting said A blocks with a difunctional diisocyanate in which one isocyanate moiety is at least about five times as reactive with the terminal hydroxyl group of the A blocks as the other isocyanate moiety, whereby the more reactive isocyanate moiety tends to react with the terminal hydroxyl group of the A blocks, leaving the less reactive isocyanate moiety free and unreacted, and adding di-, tri- or tetrafunctional B block to the end-capped A blocks at approximately the stoichiometric ratios that they are intended to be present in the thermoplastic elastomer such that the free and unreacted isocyanate moiety on the end-capped A block reacts with a functional moiety of the B block to produce ABA or AnB thermoplastic elastomers.

Inventor: TRAVIS ROBERT L JR
IPC: G06F9/54
Filed: 1991-08-13
Abstract: A method and apparatus providing for the interaction of processes in an object-oriented manner by which a system manages "classes" of data instances and applications rather than managing the data itself.  The names of classes may be stored in a data base which also contains other information about the classes, such as certain common attributes of applications or instances which are supported by the classes.  Applications can remotely invoke other applications by sending messages with parameters.  Using the message names, as well as information about the classes of certain parameters and certain preference information, a reference to a specific method is selected from the data base.  That method will perform the operation specified in the message.  Other information in the data base is then used to locate and execute the actual code to implement the referenced method.

Abstract: A light source device that converts a beam of light radiated from an optical fiber-type second-harmonic generating element to a parallel beam of light filled with a bundle of rays up to a central portion of the parallel beam by causing a portion of the beam of light to pass through an apex of a conical surface.  The light source device is unlikely to be affected by the spherical aberrations of members constituting an optical system such as lenses, which makes it unnecessary to make the component members of the optical system special, thereby simplifying the  optical system.

IPC: H01S5/062
Filed: 1991-09-20
Abstract: The operating point is stabilized at the MAX or the MIN of its optical frequency discriminating characteristic.  Under the stabilized operating point, the detected difference between the average of the light intensity and a set value is fed back to a data modulator so that the average value converges on a set value then a predetermined optical frequency deviation is produced. The operating point is also stabilized at the MED of said characteristic. Under the stabilized operating point, a low-frequency signal component is extracted from an electric signal output by means of synchronous detection.   The operating point is stabilized at the MAX or the MIN of said characteristic.  Under the stabilized operating point, a low-frequency signal component is twice in frequency by means of synchronous detection.  In the fourth and fifth aspects, means such as synchronous detection is not required for the stabilization control of an operating point.

Title: Prevention of birth defects and childhood cancer
Inventor: GROGAN JACK R JR
IPC: A61K33/16
Filed: 1992-06-16
Abstract: ABSTRACT        PREVENTION OF BIRTH DEFECTS AND CHILDHOOD     CANCER     The method of the current invention to prevent birth defects and cancer is to administer low daily doses of fluoride to a mother-to-be, for the first two months of pregnancy.     In methods of preventing birth defects the general idea of the current invention - using a nutrient early in pregnancy before the defect occurs - is a well established medical practice. The one new feature of the current invention is that of using fluoride as the nutrient. This is not entirely new, as bone meal, which contains fluoride, has been used for this purpose in animal diets. Folic acid is the most well known nutrient used to prevent birth defects in humans.     In methods of preventing cancer, there are methods that teach lifestyle modifications for us humans. In animal tests there are experimental programs which are quite close to the current invention.          These experiments were on preventing a predisposition to cancer, early in pregnancy, using a nutrient (selenium), and the model is very similar to the basis of current invention. The truly unique feature of the current invention is using the nutrient fluoride.

Title: Supporting frame for a continuous transport device
Inventor: WOLF JACQUES M E
IPC: F26B15/08
Filed: 1990-12-14
Abstract: The invention relates to a support, particularly a profiled or wire frame of a continuous transport device for transporting thin and bendable objects, panels or sheets through a drying tunnel or through a tunnel for thermal treatment or the like.      This support is characterized by the shape of its surface which receives the objects to be transported. The purpose of this shape is to prebend the panels to be transported when they are received approximately horizontally so as to prevent them from bending in vertical direction under their own weight as soon as they are lifted into a quasi-vertical position for or during transport. During this second-mentioned deformation, contact points which are very detrimental to the quality of the dried products are established between the panel and the preceding wire frame.
