Title: Methods of and apparatus for reconfiguring optical fiber connector components and products produced thereby
Inventor: KOVALCHICK JOSEPH S
IPC: G02B6/38
Filed: 1986-10-30
Granted: 1991-07-02
Abstract: METHODS OF AND APPARATUS FOR RECONFIGURING OPTICAL FIBER    CONNECTOR COMPONENTS AND PRODUCTS PRODUCED THEREBY     Abstract A biconic connector includes two plugs each of which terminates a single fiber optical cable and each of which includes a conically shaped end portion.  The connector also includes an alignment sleeve having back-to-back conically shaped cavities each of which is adapted to receive an end portion of a plug.  In order to minimize loss through a connection, it becomes important for the axis of the end portion of the core of the optical fiber in the conically shaped end portion of the plug to be coincident with the axis of revolution of the conically shaped end portion.  This is accomplished by holding the plug in a fixture such that its conically shaped end portion is exposed and the fixture adapted to be turned about an axis of rotation.  Images of light launched into the optical fiber are acquired in two planes at a plurality of positions spaced apart along a reference axis.  The center of rotation of the turntable and the relative angle of the light emitted from the end portion of the plug are resolved from these images.  A device is positioned over an end of the conically shaped portion of the plug and used to determine the angle between the axis of revolution of the plug and the axis of rotation of the fixture.  The direction of the axis of the fiber core is then determined and the fixture is oriented to cause the axis of the fiber core to be parallel to the axis of rotation.  Adjustments are then made to cause the center of the images and the center of the fiber core to be coincident with the axis of rotation.  Subsequently, the end portion of the plug is reconfigured such as by grinding to cause the axis of revolution of the reconfigured end portion and the axis of the optical fiber core to be substantially coincident.

Granted: 1992-06-23
Abstract: HYBRIDIZATION PROCESS UTILIZING A  COMBINATION OF CYTOPLASMIC MALE STERILITY AND HERBICIDE TOLERANCE ATTRIBUTABLE SOLELY TO NUCLEAR GENES          Abstract of the Disclosure The present invention provides a convenient route for producing a predetermined hybrid variety of a crop which is capable of undergoing both self-pollination and cross-pollination.  Cytoplasmic male sterile plant  which also exhibit herbicide tolerance attributable solely to nuclear genes are the key plants for use in the present process.          Economical bulk planting of the key plants with either maintainer or restorer plants is made possible.  Following cross-pollination from a pollen source which lacks the herbicide tolerance unneeded plants effectively are eliminated by use of a herbicide. For instance, unwanted plants may be effectively eliminated immediately after pollination or prior to pollination in the succeeding generation (provided the requisite genes for herbicide tolerance are present therein) to make possible the existence in an unharmed state of a substantially homogeneous stand of the desired plants.  In a preferred embodiment cytoplasmic male sterile plants, plants resulting from the self-pollination of a maintainer, and restorer plants are planted in a substantially random population prior to the application of two different herbicides (as defined) at the appropriate times.  The process of the present invention is applicable to grain crops, forage crops, seed-propa-gated fruits, seed-propagated ornamentals, and industrial species.  In a particularly preferred embodiment a predetermined variety of Brassica napus (i.e., rape or improved forms thereof known as canola) is formed which is the product of cross-pollination.

Title: Method for measuring the properties of a composition consisting of a liquid and solid particles and apparatus used in the method
Inventor: KARAILA ILKKA
IPC: G01N15/00
Filed: 1987-02-24
Granted: 1991-07-30
Abstract: Abstract The invention relates to a method for measuring the properties, especially dry matter content of a com-position consisting of a liquid and solid particles. According to the method, the composition is supplied (E, 3, 9, 45) with electromagnetic radiation, whose wavelength is selected to be smaller than the small-est dimension of particles contained in a composition to be measured.  The size of a zone to be radiated is maintained substantially constant and the composition and the zone to be radiated are set in motion relat-ive to each other.  A measuring means (6, 12, 9, D) is used to measure the intensity of radiation reflect-ing or scattering back from an electromagnetically radiated zone.  The variations of intensity, caused by particles (P) travelling into, within and out of a zone to he radiated, is used to identify the configur-ations of particles and to produce, on the basis of these configurations, signals which represent the particles.  These are processed into a message pro-portional to the properties, especially dry matter con-tent of a composition.

Abstract: ABSTRACT OF THE DISCLOSURE               An   apparatus   and   method   for   the   electronic decomposition  of water  into its component free radical parts and free  electrons.   In  a  cell  containing  an  aqueous  fluid,  an electromotive force  is applied to a positive charge storage core, insulated with semi-conductive material,  and a conducting cathodic connector having a limited electrolysis bridge there-between thereby inducing the formation of an aqueous condenser, the anodic section of which consists of the positive charge storage core insulated with the  semi-conductive  material.   The  formed  aqueous  condenser  is subjected  to  overpotentials  at  which  the  dielectric breakdown of water  occurs.   The  free  radicals  produced  by  such  dielectric decomposition   serve   to   treat   most   dissolved,   suspended  or precipitate   substances   in   solution   by   oxidation/reduction reactions.   The  in-situ  treatment  process  employs  relatively  low voltages and very low current intensities and is applicable in the treatment of varous aqueous fluid such as raw sewage, without the use of chemical additives.

IPC: G06F17/30
Filed: 1988-08-16
Granted: 1991-10-29
Abstract: ABSTRACT         A method of operating a computer system to store and retrieve information in a database uses a signature file of the database that is divided into subsets.  A word signature is mapped to a particular subset during creation of the file and the same mapping information is used to retrieve the information in response to a query keyword.  Each word signature is a logical word signature and has two components a physical word signature and a subset designation field.  In this way, when information is retrieved from the database, only that subset containing the relevant word signature is scanned.  A scanner has an input section, an output section, a control, a memory with address lines and a FIFO buffer.  The control reviews information received from the data storage means and if a match occurs between a physical word signature for a query keyword and a particular physical word signature arriving from the input section, the control sends the physical word signature to the FIFO buffer together with the document identifier located subsequent to the matched physical word signature.  The control then moves on to process the next physical word signature received from the data storage means.  If there is no match, the control ignores the physical word signature and moves on to process the next physical word signature received from the data storage means.  The control is effectively capable of processing several query keywords in parallel.
