Title: Preservative composition
Inventor: WATKINS JOHN B
IPC: A01N25/04
Filed: 1986-12-17
Granted: 1992-08-25
Abstract: PRESERVATIVE COMPOSITION         Abstract The present invention concerns stable emulsions particularly useful for preserving timber, and for the treatment of other substances. Stable emulsions are produced by simultaneously bringing together and emulsifying water and oil phases under conditions of ultra high shear, wherein the emulsion also contains at least one cationic, non-ionic and/or amphoteric emulsifying agent, which emulsifies said emulsions without a chemically antagonistic reaction occurring. The invention also relates to an apparatus for producing the emulsions of the present invention wherein the apparatus facilitates the emulsification process by providing an inlet enabling the hydrophobic and hydrophilic phases the minimum possible residence time in contact with one another prior to emulsification. The invention also encompasses a process for producing the emulsion and methods of preserving cellulosic substances and applying toxicants.            GSA/66626-86CA.doc

Title: Raster correction circuit
Inventor: HAFERL PETER E
IPC: H04N3/233
Filed: 1987-02-27
Granted: 1991-01-15
Abstract: ABSTRACT In a deflection apparatus which corrects for inside pincushion distortion, a deflection winding and a retrace capacitance form a retrace resonance circuit during a retrace interval.  A trace capacitance forms a trace resonant circuit with the deflection winding during the trace interval.  A circuit branch, that includes a second capacitance and an inductance, is coupled to the trace capacitance during the trace interval to form a second resonant circuit with the trace capacitance having a resonance frequency that is substantially higher during the trace interval than that of the trace resonant circuit.  A current in the circuit branch, that is modulated in accordance with the modulated voltage, modulates the trace parabolic voltage across the trace capacitance in a manner to reduce inside pincushion distortion.  The trace capacitance acts as a bypass capacitor around the inductance during retrace to prevent the inductance from affecting the retrace voltage.

Title: System for detachably mounting semi-conductors on conductor substrates
Inventor: LEE JAMES C K
IPC: H01L23/14
Filed: 1987-05-06
Granted: 1991-12-10
Abstract: SYSTEM FOR DETACHABLY MOUNTING SEMICONDUCTORS ON CONDUCTOR SUBSTRATE      ABSTRACT OF THE DISCLOSURE A semiconductor mounting system is provided for the detachable surface mounting of one or more semiconductor dies on a conductor substrate, such as a ceramic substrate or printed circuit board.  The system employs a resilient, anisotropic conductor pad which is interposed between the semiconductor die and the conductor substrate.  The conductor pad is capable of conducting electric signals in one direction only, and insulates in the other two orthogonal directions. Thus, by compressing the semiconductor die and resil-ient conductor pad against the conductor substrate, electrical contact is established between contacts on the semiconductor die and corresponding contacts on the conductor substrate.  In the preferred embodiment, additional conductor pads are placed over the semicon-ductor dies, and a heat sink placed over the second conductor pads.  In this way, the semiconductor dies are mounted in a resilient structure for protection, while heat dissipation is enhanced by the metallic elements in the second conductor pad.

Abstract: SELF-LEVELING DROPPED WHEEL-LINE IRRIGATION APPARATUS     ABSTRACT OF THE DISCLOSURE    Wheel line irrigation apparatus provided with a plurality of rotary, impact-type, high volume sprinklers, mounted on trunk lines each of which are self leveling.  The pipeline is axially affixed to laterally spaced wheels; the pipeline including a main line, having a substantially horizontal longitudinal axis, and a plurality of dropped line portions defining cradle-like structures.  A series of trunk lines, in fluid communication with the pipeline and rotatably connected to the pipeline by support bearings, are nestled within the cradles.  Each of the trunk lines is provided with a sprinkler, rotatable about a vertical axis.          The sprinklers are maintained in the upright position, even when the pipeline is on uneven ground, as the trunklines pivot within the cradles because of the low center of gravity.  The inlet port of each nozzle is located at or below the longitudinal axis of the main line to hold oscillations to a minimum.  Each of the dropped pipeline sections may be provided with a downwardly depending pedestal, with foot for engaging the ground, once the pipeline is filled with irrigation water, to support the pipeline and to dissipate the energy of the impact arm to ground to prevent oscillation of the pipeline.

Abstract: ABSTRACT     In a method of controlling speed range shifting, an input-output speed ratio (= output speed/input speed) in a shifting means by which a power transmitting route for the pre-shift speed range is selected is detected when a shift signal to shift from a speed range in which engine brake is available to another speed range in which engine brake is also available is transmitted. An intermediate power transmitting route in which engine brake is not: available is selected after the transmission of a shift signal as long as the change of the speed ratio is within a specified range. Then, a power transmitting route for the post-shift speed range is selected based on the shift signal when the change in the speed ratio becomes bigger than the specified range.
