Filed: 1991-01-17
Abstract: VACUUM  FOR COMBINE HARVESTER            ABSTRACT OF THE DISCLOSURE       In the harvesting of a crop there is always a portion of  the  crop  that  is  lost  as  a  result  of  the  combine harvesting process.   The present device is attached to the underside of the combine and is arranged to pick up seeds and short  crop missed by the first sweep of the combine.   The device provides a fan arrangement within a housing carried adjacent the surface of the ground.  The vaccum device picks up the seeds and short crop left behind by the normal pick up action of the combine.  The present invention increases the yield  of  the  crop,  thereby  making  harvesting  more  cost efficient.
Patent CA-2035833-A1 (CA)
Inventor: EVANS ROGER
IPC: A23L29/10
Filed: 1991-02-06
Abstract: A surfactant is produced by extracting oats using ethanol or isopropanol to produce an alcohol extract, extracting the alcohol extract with methanol to produce a methanol extract and evaporating methanol from the methanol extract to produce the surfactant.  In a modification, the methanol extract is extracted with acetone and the acetone-insoluble material is recovered to provide the surfactant.  The surfactant is useful as an emulsifying agent and/or stabilizer in water-in-oil emulsions and oil-in-water emulsions, in bread making, in the manufacture of the margarine or in the formation and stabilization of aqueous foams.  An anti-spattering agent for margarine is obtainable by extracting oats using isopropanol to produce an alcohol extract and then separating an oil from such alcohol extract.

Filed: 1991-05-13
Abstract: ABSTRACT OF THE DISCLOSURE   Basically the present invention in it's most simple form or embodiment is directed to a heat exchanger which provides for at least two heat exchange surfaces and which has the combustion of the fuel, which generates the heat, take place within the heat exchanger rather than the heat of combustion being introduced into the exchanger from an external combustion chamber and wherein the flame is directed into an opening of a truncated cone which cone has a shape approximating the shape of the flame and wherein the tips or ends of the flame "play" on an arcuate surface which is in thermal energy transfer communication with fluid to be heated which is at the unheated or ambient temperature. Additionally, note that the fluid, air in the case of a hot air system, is introduced into the passages where heat exchange will take place, and directed toward the hottest region of the combustion chamber. This is, the coldest air comes into thermal contact with the hottest region providing for maximum heat exchange. The flame is introduced into the combustion chamber in a direction which is essentially parallel to the axis of the cylindrical device. As a consequence the flame does not impinge onto any substantially flat or planar surface. Because of the nature of the construction of the nozzle etc., the flame forms into a cone configuration allowing thorough mixture with the combustion air and thus providing for complete and efficient combustion. The structural details and the pressures that are developed within the combustion chamber and the combustion region, cause the flame to "play along the conically configured walls of the truncated portion defining the combustion chamber and to impinge onto the curved/arcuate surface which conductively transfers heat to the air or fluid entering the first heat exchange volume or space. The heat of the combustion gases is given up to the fluid in basically five (5) heat exchange volumes of the device.

IPC: H01L31/04
Filed: 1991-05-31
Abstract: ABSTRACT OF THE DISCLOSURE         An energy-generating plant including a solar generator, having  solar  cells,  for producing  electrical  energy.    The electrical energy is supplied to a direct current converter, the output power of which may be used to charge an energy storage system, such as batteries.  The input resistance of the direct current converter is adapted, such as by a microcomputer, to the maximum power point (MPP) of the solar generator, the MPP being dependent upon the solar insolation and the temperature of the solar cells.  At start up of the plant, or when there is a change of power at the output of the direct current converter, a search process is carried out to attain the MPP of the solar generator. The energy storage system may be used to energize an electric motor for driving the propeller of a ship.

Title: Tamper evident closure using microcapsules
Inventor: ILER HOWARD D
IPC: B65D25/20
Filed: 1991-07-10
Abstract: This relates to the provision of a vacuum identifying button of a conventional closure for containers with encapsulated microcapsules containing a suitable dye. While the button is in its depressed, concave configuration, a coating surrounding the microcapsules is cured and caused to bond to the microcapsules. When the button everts to project upwardly and have a convex configuration, the coating is tensioned causing the microcapsules to rupture and release the color forming dye materials thereof, if desired, the evidence of button flipping or tampering may merely be in the form of a colored areas, such as a stripe. In a modification, the effected colored areas may be in a design to present a warning or message. For example, a simple message such as "OPENED" may be effected.

Title: Photosensitive printing component with a printing and a covering layer of differing solubility and a process for developing it in one working cycle
Inventor: TELSER THOMAS
IPC: G03C8/36
Filed: 1990-03-14
Abstract: - 46 -          0.2. 0050/40655 Abstract of  the Disclosure:   A novel photosensitive recording element having a dimensionally stable substrate (A), a photopolymerizable relief-forming recording layer (B), which may consist of two or more individual layers (B), and an optically transparent top layer (C) firmly adhering to the surface of (B) is used for the production of  a  flexographic  relief printing plate.   Imagewise exposure of the photopolymerizable relief-forming record-ing  layer  (B)  of  the novel photosensitive recording element to actinic light results in a difference between the solubilities of its exposed and unexposed parts, so that its unexposed parts can be washed out (developed) with a solvent.  On the other hand, the optically tranq-parent top layer (C) of the novel photosensitive record-ing element is insoluble or nonswellable in the relevant solvent.   The imagewise exposed novel photosensitive recording element can nevertheless be developed in one operation with the aid of an emulsion of the water-in-oil or oil-in-water type.   These emulsions are also suitable for developing imagewise exposed photosensitive recording elements whose photopolymerizable relief-forming record-ing layers (B) consist of two or more individual layers (B) having different solubility properties. In this case too, development is effected in one operation.

Title: Method and apparatus for forming migration free glass fiber packages
Inventor: FLAUTT MARTIN C
IPC: D01D5/084
Filed: 1991-08-23
Abstract: ABSTRACT OF THE DISCLOSURE Energy efficient process and apparatus are disclosed for forming glass fiber packages on a collet (24) which are free of migration.  Air from around the fiber forming bushing (12) is passed beneath the bushing whereby it is heated by bushing heat and the heated air is then drawn into a chamber (36) through which the glass fibers (16) pass in heat transfer contact with the heated air.  This heat transfer contact causes the water or solvent in the applied size to be evaporated and results in a migration free package.
