Title: A content recommendation system and method
Inventor: GAUDE NICOLAS
IPC: G06F17/30
Filed: 2009-11-04
Abstract: A content recommendation method and system including providing a plurality of content items, a number of items including the plurality of content items is designated as N. The content items are listed in a content catalog, and assigned a uniform resource identifier (URI). Each of the content items are represented as a unique point on a two dimensional plane having x and y coordinates. Each point is associated with an initial weighting of zero which is incremented each time a content item is accessed. The x and y coordinates of each unique point are changed based on a plurality of user requests for other content items. The distance between the unique point and a multiplicity of other points is determined and recommending content associated with a point that is closer to the unique point than any of the other points. In use this method may be implemented by defining an NxN matrix IM(n,m) which includes a total number of requests for a content item assigned to a URI m from a user who last requested a content item assigned to a URI n. The transpose of IM is determined and added to IM resulting in a matrix sIM. A column of sIM corresponds to an item currently being viewed and is sorted to provide recommendations of further content of interest.

Abstract: Resinous copolymers of the polyamide type are obtained by heating in the liquid phase a mixture of an anhydride of an N-carboxyl alpha-amino acid and an o -amino acid having at least 6 carbon atoms in the molecule.  The N-carboxyl anhydrides have the formula <FORM:0670721/IV (a)/1> where R is hydrogen or a monovalent alkyl, aryl, or alkylaryl radical which may contain a carboxy or amino group if that group is protected by esterification.  Examples of the acids from which the anhydrides are derived are glycine, alanine, leucine, norleucine, phenylalanine, tyrosine, diiodotyrosine, thyroxine, tryptophane, aspartic acid, glutamic acid, arginine and lysine. Examples of suitable amino acids are 11-amino undecanoic or undecylic acid, 10-amino decanoic or decylic acid, 10-amino decanoic or decylic acid.  In examples: (1) 100 parts 11-amino undecylic acid and 80 parts e -N-carbobenzoxy-a -carboxyl lysine anhydride are mixed and melted in an oil bath kept at 210 DEG  C.  A viscous mass was obtained which was purified by solution in benzyl alcohol and precipitation with methanol.  50 parts of the copolymer were dispersed in 200 parts glacial acetic acid and hydrogen bubbled therethrough, 100 parts phosphonium iodide were added and the reduction continued for two hours.  The semi-solid obtained after purification was soluble in glacial acetic acid; (2) 33 parts N-carboxyl phenylalanine anhydride and 67 parts 11-amino undecanoic acid were heated for 1 hour at 200 DEG  C.; (3) 11-amino undecanoic acid and N-carboxyl-glycine anhydride were similarly reacted.  The Specification as open to inspection under Sect. 91 states that the N-carboxyl amino acids themselves or their derivatives may be used instead of their anhydrides.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,016,288. Fluid pressure servomotor control systems. ROBERTSHAW-FULTON CONTROLS CO. March 15, 1963 [March 16, 1962], No.10432/63. Heading G3P. A pneumatic relay comprises a body having two interconnected compartments 42, 44 each divided by a diaphragm 46, 50 into two compartments 48, 52 on the outer sides of the diaphragms, the space between the diaphragms being connected to atmosphere through a port 56. The diaphragms are connected by a member 72, a nut 82 and a valve actuating member 80, the member 80 being hollow with ports 90 and an end portion which cooperates with a valve 66 to control the flow from chamber 52 to atmosphere. The valve member 66 also carries a flange 68 which controls flow from an inlet 25 to the chamber 52. A signal pressure outlet port is connected to the chamber 52 by a passageway 98 and a passage 102 connects as second inlet port to chamber 48. In operation two variable pressures are fed to the inlet 25 and the chamber 48. When the pressure in chamber 48 exceeds the pressure in chamber 52, the valve 68 is opened and fluid flows from the inlet 25 to the chamber 52 and to the outlet. When the pressure in chamber 48 is below that in chamber 52 the valve member 80 lifts to connect chamber 52 to the atmosphere. The output pressure is thus the lower pressure fed to chamber 48 or inlet 25.

Title: Cable joint structure
IPC: H02G15/18
Filed: 1926-03-22
Abstract: 273,225. Simons, D. M., and Barbour, F. D. March 22, 1926. Cable joints; sleeve couplings.-A cable joint comprices two cable ends with cut-away envelopes of machine-laid insulation and united conductors, and a wrapped-on web of insulation surrounding the union being of the full width of the space between the cut-away ends of machine-laid insulation, and in a single convolution (i.e. not progressing longitudinally) filling all the interval. In its simplest form, Figs. 1 and 2, the invention comprises cutting away the sheath 1 and the envelopes 2 of insulation and exposing the conductors 3, which are connected by, for example, a. sweated-on metal sleeve 4. The insulation is, as shown, cut away in steps and the sleeve and conductor are covered with insulation up to the first step so as to form a surface for wrapping on the insulation 6. This insulation is of proper length and width to fill the space between the successive steps and may be an integral strip or comprise a. succession of pieces, the ends 7 being adapted for filling the spaces between the sleeve 4 and insulation 2. The material used may be paper or muslin and is ordinarily impregnated with oil or varnish. The strip or strips are applied to the cable as shown by the relative positions in the drawing, and a machine with knives may be used for cutting one strip to shape out of a roll of maximum width, as explained in Specification 272,626. The casing 5 may be filled with insulation, but preferably the strip is continued to form a body 9, as in Fig. 5, the edges of the strip carrying metal strips forming extensions 10 of the sheath, so as suitably to confinethe electric field. In the form shown in Fig. 6, the lowest steps have re-entrant recess 20, which are filled by the sleeves 4 so as to present a surface 41 flush with that 21 of the lowest steps. The sleeve 4 may be of low-fusion metal, cast into place, or it may be performed and sweated into place. The insulation may end flush with the insulation 2 or may be extended to form the body 9, as in Fig. 5. The ends of the insulation 2 may be tapered instead of stepped, and the applied insulating strip will be correspondingly tapered in form. The insulation may be anchored to the conductors 3 by cementing, in which case any impregnating material will be dissolved out in ether and the tip of the strip so prepared will be tapered bv cutting to a point. Alternatively, the sleeve 4 will be longitudinally slotted to receive the end of the strip and afford enough anchorage. For filling the casing with liquid insulation an expansible reservoir 50 is attached to the casing and sealed.

Title: Process of preparing water-soluble phosphates
IPC: C05B7/00
Filed: 1965-03-15
Abstract: Water-soluble calcium phosphate is prepared by decomposing phosphate rock with excess HNO3 of e.g. 45-65% concn., extracting this decomposition liquor with a polar organic solvent which is poorly immiscible with H2O to remove most of the acids and part of the Ca(NO3)2, extracting this extractor soln. with a polar organic solvent poorly immiscible with H2O which preferentially dissolves HNO3, such that Ca(NO3)2 and H3PO4 remaining in the solution are converted to Ca(H2PO4)2 MH2PO4, where M is alkalimetal or NH4, may be prepared by adding M2SO4 to the aqueous extractor solution as above, separating the pptd. gypsum, and extracting the HNO3 as above.  The decomposition liquor may be extracted by an ether or ketone but preferably by an aliphatic alcohol having 4-6 carbon atoms in the molecule.  The HNO3 may be extracted by an aliphatic ketone or ether. Some Ca(NO3)2 may be removed from the decomposition liquor by partial crystallization before extraction.  The process may be carried out in a continuous manner by recycling the organic solvent from the first extraction stage after washing with H2O; crystallizing the phosphate from the aqueous extractor soln. after removal of HNO3 therefrom, and recycling the phosphate mother liquor to the HNO3-extraction stage, and neutralizing the HNO3-containing solvent, e.g. with aq. NH3, and recycling this solvent after removal of the nitrate produced.  A flow-diagram for such a continuous process is described.
