Abstract: ABSTRACT OF THE DISCLOSURE    A process of preparing a shredded wheat product.  The process includes cooking whole wheat berries with water to at least partially gelatinize the wheat starch.  The bran layer of the whole wheat berries is intact and does not have any penetrations therein before the cooking begins.  The cooked wheat berries are treated with an isoamylase.  The treated, cooked wheat berries are tempered for a sufficient period of time to retrograde a substantial portion of the starch in the berries.  The process allows the use of a tempering time which is much less than the tempering period in the conventional or commercial process of preparing shredded wheat.  The tempered wheat berries are formed into a shredded form and then baked or toasted.

Title: Pipeline packer improvements
Inventor: CAMPBELL DOUGLAS C
IPC: E21B33/12
Filed: 1990-05-24
Abstract: ABSTRACT          The pipeline packer described herein typically includes a main body adapted for propulsion through the pipeline in an axial direction.  A brake shoe support assembly is located on the main body and a plurality of circumferentially spaced brake shoes capable of gripping the interior wall of the pipeline are mounted to the support assembly.  Fluid pressure activated means are associated with the brake shoe support assembly for urging the brake shoes radially outwardly into gripping engagement with the pipeline to secure the main body in a desired location in the pipeline against the pipeline pressure forces acting thereon.  A pair of annular wedging means are also mounted to the main body for axial movement toward each other as the fluid pressure activated means acts on the brake shoe support assembly to urge the brake shoes into gripping engagement.  An annular sealing member of elastomeric material is located between the annular wedging means and is adapted to co-operate with same so as to expand radially outwardly as the annular wedging members move toward each other.  The packer also includes fluid pressure supply and control means connected to the fluid pressure activated means so that on demand the brake shoes are urged into gripping relationship with the pipeline while at the same time the annular sealing member is expanded into sealing engagement with the pipeline wall.

Patent CA-2024205-A1 (CA)
Inventor: SCHWEITZER EDMUND O JR
IPC: G01R31/02
Filed: 1990-08-29
Abstract: A fault indicator for indicating the occurrence of a fault current in a monitored electrical conductor of an AC power distribution system utilizes a liquid crystal display having independent "F" and "N" display elements.  A rectifier circuit capacitively coupled to the conductor charges a first capacitor in the presence of voltage on the conductor.  A second capacitor is connected to the first capacitor by a first reed switch in magnetic communication with the conductor.  Upon occurrence of a fault current the reed switch closes and a portion of the charge on the first capacitor is transferred to the second capacitor, which is connected to the "F" display segment electrodes of the liquid crystal display to cause an "F" to be displayed.  The fault indication can be reset either by the slow discharge of the second capacitor, or by discharging the second capacitor through a second reed switch manually actuated by a magnetic reset tool from outside the fault indicator housing.  The "N" display segment electrodes are capacitively coupled to the monitored conductor and system ground to provide an "N" display indicating that voltage is present on the conductor.                              .

Title: Optical branching waveguide
Inventor: KOREN UZIEL
IPC: G02B6/125
Filed: 1991-04-29
Abstract: An optical branching waveguide having low radiative loss and low back-reflectivity is described.  By employing between the branches a region having a gradual decrease in effective refractive index along the direction of optical propagation, the deleterious effect of wedge tip truncation can be reduced.

Abstract: A facsimile apparatus capable of informing an operator of data such as operable time of the facsimile apparatus, the number of documents transmittable and receivable based on the quantity of electric charges remaining in the battery comprises a clock for generating time data and a monitor for monitoring the quantity of electric charges remaining in the battery.  The monitor calculates the charging time of the battery based on the time data.  The charged quantity of the battery from the time when the battery started to be charged to the cur-rent time is determined from the charging time.  The operation time of the facsimile apparatus driven by the battery in each of the operation modes is calculated based on the time data.  The consumed quantity of elec-tric charges in the battery is measured from the opera-tion time.  The quantity of electric charges remaining in the battery is calculated from the charged quantity and consumed charge quantity.  The operable time of the facsimile apparatus, the number of documents transmitta-ble and receivable for each of the operation modes are displayed based on the current quantity of electric charges in the battery.  A detector is provided which detects fall in the quantity of electric charges remain-ing in the battery below a predetermined value in a normal reception mode.  The operation mode of the facsim-ile apparatus is switched from the normal reception mode to a memory reception mode based on the output from the detector.
