Abstract: HARVESTER HEADER WITH TRANSVERSELY  INCLINED, OVERLAPPING CONVEYORS                   Abstract of the Disclosure A multirow harvester header comprising a plurality of pairs of crop conveyors.  Each conveyor pair corresponds to a single row of crop and is used to converge and convey a single row from a standing position in the field into the crop receiving throat of the harvester attached to the rear of the header.  A first and second pair of the conveyors is inclined transversely and down-wardly in a direction toward a third and fourth pair of the conveyors.  The third and fourth pair of conveyors are inclined transversely and downwardly om the direction of the first and second pair of conveyors.  The second and third pair of conveyors are vertically spaced above and in overlapping relationship respectively with the first and fourth pair of conveyors.  The transverse inclination and overlapping relationship of the convey-ors enables the rear drive shafts of each pair of conveyors to be closely spaced together in front of the crop receiving throat of the harvester.  The transverse inclination also enables the forward ends of the conveyors and associated crop cutters to be positioned at an equal distance above the ground and in a trans-verse vertical plane at the forward end of the header.  Additional space adjacent the harvester throat is saved by driving two of the conveyors of the first and second pair of conveyors from a common rear drive shaft and by driving two of the conveyors of the third and fourth pair of conveyors from a common drive shaft.  Sealed gear cases are provided for the conveyor drive means.

Abstract: Abstract:    The invention provides a process for determining the soundness, and the soundness-dependent germinative ability, of sowing seeds.  The process is based on detecting the characteristic difference between the acoustic excitation response functions of sound and damaged seeds.  The seeds are excited by an acoustic signal and by examining the response functions a comparison is performed to decide whether the seeds are right or damaged.  Apparatus for carrying out the process is also provided and includes a feed tank, a seed feeding mechanism, a sensing chamber and a vibration sensor for detecting acoustic signals within the chamber, the output of the vibration sensor being connected to a signal processing unit.

Abstract: ABSTRACT  OF  THE  DISCLOSURE       In the formation of a paper web from stock fed to a Foudrinier wire, the Zeta Potential is an important parameter. A measure of Zeta potential is made by measuring the streaming potential developed in a vertically-arranged cell having a horizontal mesh therein on the underside of which a pad of fibres and fines is formed by pumping stock into the lower part of the cell. Electrodes located in the cell above and below the pad are used to obtain a measure of streaming potential at a given pressure differential across the pad.   A pressure transducer is mounted in the lower part of the cell.   Corrections are made for temperature and conductivity by sensors in the stock feed path to the cell.   A microprocessor control and measuring circuit is disclosed which sequences valves for controlling the flow of stock and flushing fluid to the cell and which measures the relevant parameters.

Abstract: ABSTRACT        A process for producing a stable glass-ceramic product useful for storing radioactive nuclear waste products for extraordinarily long periods of time without danger to the environment, in which liquid wastes having high level radioactivity are passed through an ion exchange medium, such as a titanate to deposit the highly radioactive materials thereon and produce a low level radioactive liquid waste which can be safely disposed of in a less rigorous manner than high level wastes is described.  The ion exchange medium carrying the highly radioactive materials is heated, with any additional glass forming materials which may be necessary, to form a melt having a composition in the range:                      where M is selected from Na, K; M1 is selected from Ca, Ba, Sr; M11 is selected from Al, B, Fe, Cr; M111  is selected from Zr, Sn, Zn and M1V  is selected from P, Ta, Nb.  This glassy composition is cooled and then reheated to a selected temperature, dependent on the composition, in the range 950°C - 1050°C to effect devitrification into a glass-ceramic product comprising crystalline sphene in a glassy matrix.          Preferably most of the radioactive material will report in the crystalline sphene phase.

Abstract: Abstract of the invention A whey protein concentrate product suitable for formulation with other ingredients to provide infant food formulas that remain stable after being heat sterilized. The whey protein content is derived from the retentate fraction produced by ultrafiltering cheese whey. The produce also has a lactose content which is preferably obtained by the ultrafiltration of cheese whey and the controlled partial demineralization of the resulting lactose rich permeate as by electrodialysis. The process comprises subjecting a cheese whey having its protein content in undenatured form to membrane fractionation, to thereby produce a protein rich retentate fraction and a lactose rich fraction. The permeate fraction is subjected to electrodialysis to reduce its mineral salt or ash content to a predetermined value. The electrodialyzed permeate fraction may then be blended with the retentate fraction to form a product suitable for use as an infant formula ingredient.

IPC: C05C1/00
Filed: 1984-01-13
Granted: 1988-04-12
Abstract: MANUFACTURING AND USING NITROGEN FERTILIZER SOLUTIONS ON A FARM To make non-pressure nitrogeneous fertilizer solutions, nitrogen oxides are prepared in a continuous process by burning ammonia in contact with a cobalt oxide catalyst started by an electric arc without preheating the gases. This burning forms nitrogen oxides which are reacted under negative pressure in a twostage system. Nitric acid is formed in the first stage from a portion of the oxides by oxidizing them to nitrogen dioxide and reacting the nitrogen dioxide with water. In the second stage, the remaining nitrogen oxides are reacted at a pH between 8.0 and 8.4 in a gas-liquid contacting apparatus with an ammonium hydroxide reaction liquid, formed by mixing ammonia and water. The ammonium nitrite solution formed in the second stage is mixed with the nitric acid at a pH below 0.2, resulting in a solution of acidic ammonium nitrate to be flowed to the fields with irrigation water.
