Abstract: Abstract of the Disclosure A potato handling apparatus includes a roller conveyor for receiving a continuous stream of irre-gularly sized potatoes with an aligning section at the upstream end of the conveyor which includes a series of two parallel flaps for turning and pushing the potatoes lengthwise into the valleys of the roller conveyor.  To eliminate all but one potato from each valley, a singulating section is provided.  The singulating section includes a rod longitudinally disposed adjacent one edge of the roller conveyor and a series of parallel overlapping sprocket-like discs which extend diagonally across the conveyor to a down-stream position which is inwardly spaced from said edge of the conveyor.  Each disc has cogs formed on the periphery thereof which perforate the valleys in succession to a depth which prevents the potatoes from being pinched between the discs and rollers.  The discs sequentially push all but one of the potatoes in a res-pective valley over said edge of the conveyor, while the rod prevents single potatoes not acted upon by the discs from wandering over the outside edge of the conveyor. A resilient rotatable member is pivotally mounted above the passageway by the downstream disc to retain longer potatoes on the conveyor.                             -1a-

Abstract: ADHESIVE FASTENER ARTICLE                  Abstract of the Disclosure This invention relates generally to an adhesive fastening device for securing a secondary workpiece to a primary work surface.  The device includes a plate-like base of ferromagnetic material having a substantially uniform, predetermined cross-sectional thickness and carries a fastening element on the upper surface thereof and a layer of heat activatable adhesive on the undersurface thereof.          A plurality of protuberance means of limited height and limited surface area are formed upwardly from the base with the protuberance means being located in a pair of laterally spaced, parallel lines.  Each line is closely adjacent to the perimeter of the layer of heat activatable adhesive, so that a U-shaped inductor core may be positioned over the base with the end surfaces of the legs of the core abutting the laterally spaced lines of protuberances thereby minimizing the heat loss from the device as the device is heated through the completion of a magnetic flux circuit between the legs of the core with the base of the device.

Abstract: ABSTRACT     Magnetic fields of electrical operating components of electric-traction-motor powered vehicles, especially diesel electric and all-electric railway locomotives, are sensed as the vehicles pass given loca-tions along their respective paths of travel, and the signals so obtained are processed to yield perceptible outputs, such as oscillograph charts or computer printouts, indicative of performance and any maintenance work that must be done for maximum utilization of available energy. In instances in which speed of the vehicle is a significant factor, that infor-mation is ascertained and utilized in the processing of the signals derived from sensing the magnetic fields. The apparatus comprises one or more magnetic field sensors, such as standard relay coils, strategically located with respect to the path of travel of the vehicle, and information processing equipment adapted to receive signals from the sensors and speed information, if significant, and to provide a perceptible output indicative of performance and any maintenance work required.

Abstract: ABSTRACT A power supply and a method for providing in a con-venient and inexpensive way an unlimited range of direct cur-rents with superimposed alternating sinusoidal or non-sinusoidal currents to a single load or to a number of loads in parallel.  The novel power supply is derived from a con-ventional one by purposely unbalancing the AC potentials of the load terminals so that an additional AC voltage drop appears across the load.  Unbalancing of the AC potentials can be ac-complished by directly connecting one of the load terminals to different points along a special unbalancing transformer winding and/or by connecting a capacitor between a load ter-minal and different points of this unbalancing winding.

Abstract: ABSTRACT OF THE DISCLOSURE   A linear row of MIS capacitors as sensor elements are arranged on a doped semiconductor body.  The MIS capacitors are separated in the semicon-ductor body by a potential threshold for the optically generated minority carriers.  The potential threshold, for example, can be generated by means of a field shield electrode.  By means of transfer gates the sensor elements are alternately coupled with CCD shift registers.  An oppositely doped over-flow drain which is contacted with an overflow electrode connects to the nar-row side of each sensor element which is opposite the corresponding transfer gate.  Each overflow drain is separated from the sensor elements by a poten-tial threshold for the minority carriers which is smaller than the potential threshold between the sensor elements themselves.  A varying thickness of the oxide layer, a varying doping and/or parts of the field shield electrode can serve for adjusting the potential threshold.  In this manner, in a sen-sor of high component density for the electronic image gathering, an over-flow arrangement is incorporated without any additional space requirement.

Abstract: Abstract of the Disclosure An improved method for treating calcium phosphate sources such as bone phosphate and phosphate rock with fluorosulfonic acid in the presence of a limited a amount of moisture whereby over 98.00% of the phosphorous is converted to volatile compounds that can be subsequently hydrolyzed.  A substantial excess of fluorosulfonic acid is utilized to contact the phosphate ore as a slurry.  The phosphorous products are primarily phosphorous pentafluoride and phosphorous oxyfluo-ride, and to a limited extent difluorophosphoric acid.  A trace of water apparently catalyzes the reaction.  The pro-duction of phosphorous pentafluoride is favored by up to one part of water to eight parts of ore by weight in the presence of excesses of fluorosulfonic acid. The method includes the hydrolysis of the volatile compounds to phosphoric acid and hydrogen fluoride.  Hydrogen fluoride is then recycled to react with the required sulfur trioxide to make the require-ment of fluorosulfonic acid for the process.  Fluorosulfonic acid not consumed in the process is recovered for reuse in the process.  Dependent on the form of silica impurities in the ore, a net production of hydrogen fluoride may be ob-tained from the fluoride content of the rock.  The process is relatively self-sustaining as far as hydrogen fluoride used for making fluorosulfonic acid requirements is concerned.          Sulfur trioxide is essentially the net reagent required to treat the ore to produce the volatile phosphorous interme-diates for subsequent conversion to phosphoric acid and hydrogen fluoride.
