Title: Method for manufacture of neutron  absorbing articles
Inventor: OWENS DEAN P
IPC: G21F1/10
Filed: 1978-10-04
Granted: 1981-12-08
Abstract: ABSTRACT OF THE DISCLOSURE:             Neutron absorbing articles, such as those in plate form suitable for use in a storage rack for spent nuclear fuel and having such properties as to make them useful in such application for long periods of time, are made by an improved one-step curing method in which a mixture of boron carbide particles, powdered phenolic resin and a minor proportion of a liquid medium which boils at a tempera-ture below 200°C., preferably water, is compacted to desired article form and is cured at an elevated temperature, without simultaneous imposition of pressure in compacting or pressing means, so as to cause bonding of the irreversibly cured phenolic polymer resulting to the boron carbide particles and production of the neutron absorber in desired form.  In preferred aspects of the invention the proportions of boron carbide particles, resin and water are respectively,60 to 80, 20 to 40 and 2 to 8, the resin is a phenol formaldehyde two-stage resin containing hexamethyienetetramine in sufficient quantity to provide formaldehyde to cure it, the resin is of a molecular weight in the range of 1,200 to 10,000, e.g., 6,500, the resin and the irreversibly cured polymer resulting are substantially free of halogens, lead, mercury, sulfur, filler, plasticizer and solvent and the boron carbide particles contain no more than 2% of iron and no more than 0.5% of B2O3.  The described method is also employable when a proportion of the boron carbide particles, e.g., 1/10 to 9/10, is replaced by a diluent compound, such as silicon carbide, alumina, silica graphite, amorphous carbon or  mixtures thereof.

Title: Method and apparatus for tallying food items selected  on menus
Inventor: LUM JACKSON
IPC: G06K15/00
Filed: 1978-11-21
Granted: 1980-12-02
Abstract: ABSTRACT OF THE DISCLOSURE     A system which processes menus on which food items have been selected.  The menu is encoded to have a plurality of detecting paths, with a first transverse row of preassigned markings in selected areas of the paths.  Additionally, there are provided uniform indicated spaces arranged in a subsequent transverse row on the menu.  Each indicating space is associated with a respective food item.  The user selectively places marks in the indicating spaces indicating desired food items.  The system detects the preassigned markings in the first row and in reponse thereto initializes circuitry to register information identifying the menu, specifically the menu diet and meal.  The system then detects the additional markings placed in the indi-cating spaces, and a recording circuit responds to these additional markings to record a count for each food item selected for that particular identified menu diet.  The system then tallies the total count for each food item of all the different types of menus.

Abstract: Abstract Capacitive phase shift circuitry for supplying current to the two coils of a synchronous motor at a desired voltage and phase relation, without the need for a voltage drop resistor.  The absence of any substantial resistance in the phase shift network reduces electrical power dissipation (and resulting heat) and makes possible a physically compact circuit.          Switch means may be used to enable reverse motor  rotation.

Abstract: ABSTRACT OF THE DISCLOSURE   A process is provided for preparing hydrophobic silicon dioxide. The process includes treating silicon dioxide having a surface area of at least 50 m2/g with an organosilicon compound containing from 2 to 4 silicon atoms per molecule, in which at least 2 hydrocarbon radicals are bonded to each silicon in atom, and in which any silicon valences which are not satisfied by hydrocarbon radicals are satisfied by siloxane oxygen atoms, and at least one tin compound containing Sn-bonded halogen and/or organic radicals.  The in-herent dangers   of corrosion caused by the use of an acid is avoided by the process of this invention, to provide a silicon dioxide exhibiting a higher degree of hydrophobicity that that produced by prior art processes.  These products may be used as fillers for thermoplasties, as opacifiers in varnishes, as components for fire control, and for thermal insulation.

Digital filter for filtering non-uniformly quantised pulse code-modulated signals formed by a sequence of code words each comprising a segment number s(i) and a mantissa number m(i). This digital filter com-prises a modifying device to which the mantissa numbers m(i) are applied for generating modified mantissa numbers E(i). The numbers E(i) are each multiplied by the magnitude of a filter coefficient, for generating first product numbers z1(i). Thereafter those numbers z1(i) are each multiplied by a number 2B(i), B(i) being either equal to s(i) or equal to s(i)-1, so that second product numbers z2(i) are obtained which are applied to an accumulator.

Title: Process for increasing oleoresin synthesis  in pinus species
Inventor: PETERS WILLIAM J
IPC: A01N43/40
Filed: 1979-01-15
Granted: 1982-05-11
Abstract: ABSTRACT OF THE DISCLOSURE       Stimulation of oleoresin production associated with living cells can be chemically induced with dilute systemic application of ethylene or ethylene-releasing compounds.  One such ethylene-releasing compound is 2-chloroethyl-phosphonic acid, sold under the trademark Ethrel.  A further increase in oleoresin production can be accomplished by using ethylene-releasing chemicals in combination with the bipyridilium salts, diquat (1,1'ethylene-2,2'-dipyridilium salt)or paraquat (1,1'-dimethyl-4,4'-dipyridilium salt Through the application of ethylene-releasing chemical in combi-nation with a bipyridilium salt, the effect of lightwood inducing chemicals is expanded over a larger portion of the treated tree, and more oleoresin is produced.  Oleoresins are extracted from the trees by known methods, and the naval stores products are recovered therefrom.

Abstract: SPECIFICATION                     Abstract of the Disclosure The distillative freezing process disclosed is useful in separating a mixture containing at least two volatile components, denoted respec-tively as A-component and B-component, by simultaneously vaporizing the two components from the mixture under a sufficiently reduced pressure to simultaneously crystallize B-component.  The vapor mixture obtained is brought to a condensed state either by a simple condensation operation or a condensation-desublimation operation without being substantially pressurized.  The process may be conducted to completely eliminate the liquid phase and bring the mixture into the two phase solid-vapor region.           Then, the solid phase in no longer contaminated by the adhering liquid phase and gives a high purity B-component on melting.  The process is particularly useful in separating mixtures containing close boiling components, such as styrene-ethyl benzene mixtures, p-xylene-m-xylene mixtures and ethylene-ethane mixtures.  The process can therefore be used in producing high purity monomers for the plastic industries and high purity chemicals for other industries.

Abstract: ABSTRACT OF THE DISCLOSURE A fluid fuel burner system for minimum production of NOX under vary-ing rates of fuel firing and varying rates of combustion air or oxidant supply, which comprises a fuel burner including means for burning liquid and gaseous fuels.  Liquid fuels are burned in an axial burner tube, and the gaseous fuels are burned in a plurality of gas burner tubes located in a circle coaxial with the liquid burner.  A first air or oxidant plenum supplies primary-plus-secondary air or oxidant, the primary air or oxidant going to the liquid burner and the secondary air or oxidant going to the gas burner. The total of primary plus secondary is less than stoichiometric flow so that the combustion of the fuel in a first combustion chamber provides a reducing atmosphere to preclude the formation of NOX.  Means are provided for independ-ently controlling the primary air or oxidant flow compared to the secondary air or oxidant flow, or vice versa.  A second air or oxidant plenum provides tertiary air or oxidant to a second combustion space downstream of the first combustion chamber.  Control means provide independent control of the primary-plus-secondary air or oxidant flow to the first plenum as a selected ratio to the tertiary air or oxidant, that flows to the second plenum.
