Title: Detecting Edge Pixels In An Image
Inventor: BIRTLES ALAN PETER
IPC: G06F17/30
Filed: 2007-10-31
Abstract: Edge pixels in an image are detected by replicating at least part of a first image to create at least one replicated image which is then spatially transform by a distance of one or more pixels relative to the first image. An edge pixel matrix indicating the presence of edge pixels in the at least part of the first image is then produced wherein the matrix comprises a plurality of matrix elements, each matrix element corresponding to a pixel in the at least part of the first image. A value for each element of the edge pixel matrix is then generated in accordance with a logical exclusive OR (XOR) combination of a same attribute of a pixel in the first image with one corresponding pixel from at least part of the transformed image, wherein said corresponding pixel from the transformed image is of a matching position to the pixel from the first image, the logical combination resulting in a first value only if both the pixels have the same attribute.

Title: Integrated lubrication module for compressors
Inventor: CZECHOWSKI EDWARD S
IPC: F16N29/00
Filed: 2007-02-15
Abstract: In accordance with certain embodiments, the present invention provides a modular approach to a lubrication package. Certain components such as the filter and oooler are directly connected to a block that has connections to accept them and internal porting to establish the proper flow paths for circulation, cooling and filtration of the circulating lubricant. The block can accept one or more coolers and one or more filters. The isolation valving for redundant equipment can also be integrated into the block. Many connections that had been used in past designs for the piping network are integrated into the block. The block can also be close mounted to the reservoir while a submersible pump further saves space and piping connections. Indeed, having the ability to maintain mechanical equipment (e.g., remove and replace filters and coolers) without shutting down, allows for continuous process flow, which eliminates down-town scheduling, loss of product and/or redundant backup, all of which comes at a considerable cost.

Title: Data allocation in OFDM based on detected interference level
Inventor: STRONG PETER
IPC: H04L1/00
Filed: 2007-07-26
Abstract: A wireless broadband communications system that provides increased reliability in environments in which portions of the available operating frequency band are subject to interference. The system determines whether the operating frequency band is being subjected to interference. If so, then the system determines (302) whether such interference is affecting one or more portions of the band. If interference is affecting just portions of the band, then the system reduces (304) the data rate and the number of sub-carriers used to transmit data. Next, the system allocates (306) the data to be transmitted to the sub- carriers currently being subjected to the lowest levels of interference, while allocating no data to the subcarriers currently being subjected to the highest levels of interference. In this way, the system allocates the data to be transmitted to the sub-carriers occupying optimal portions of the operating frequency band, in response to detected changes in the interference environment.

Abstract: 1374984 Making cartons KEYO LOK CO Inc 9 Feb 1972 [24 March 1971 21 April 1971 (2) 9 June 1971] 7709/71 10351/71 10352/71 and 19550/71 Heading B5D [Also in Division B8] A blank is made from a laminate comprising a substrate of paper, cardboard or boxboard delaminably adhered by, e.g. microcrystalline wax to a lining of, e.g. plastics sheeting, and comprises face panels, 5, 9, a side panel 7, a part-side panel 3 connected to a side fin flange 1, and a seaming panel 11 connected to a further side fin flange 13, end closure panels on the blank including a main cover panel 34, side-gusset panels 28, 30 and 36, 38, and a flange closure panel 26, the main closure panel 34 having a flange 43, 50 provided with extensions 41, 47, and the substratum of the flange closure panel 26  being severed from adjacent end panels. To form a side seam the blank is folded as shown in Fig. 2 and carried by pushers 58 beneath a heater 65 which heats the fin flanges 1 and 13 so that when pressed together by rollers 59 the sheeting of these flanges is sealed. Theheating also frees the sheeting from the substrate, enabling a folder 60 to fold the substrate of the panel 3 and the fin flange away from the sealed sheeting. Adhesive is applied to the folded substrate by an applicator 61 and folders 62, 63 then fold the substrate so that the fin flange 1 overlies the fin flange 13. Opposed belts 64 then press the fin flanges together. There is thus formed a tube of sheeting surrounded by a tube of substrate. To form the ends of the tube, the tube is then fed to a pocket 85 in a turret at a station A. Between station A and a station B, the flange closure panel 26 is out-folded by a bar 251. At station B a member 66 forms an outward gusset fold with the panels 28, 30, a member 67 forms an outward gusset with the panels 36, 38, a bar 68 folds the cover panel on to the top of the tube. The tube is then carried beneath a bar 69, which fully folds the end panels, and beneath a heater 70, which delaminates the sheeting from the substrate. A pressure device 71 presses the heated tube end to seal the sheeting at that end. The tube is then transferred to a pocket 86 in a second turret at which a rail 73 folds the panel 26 upwardly and lifts the panel 34, members 75, 76 fold the gusset panels inwardly, a member 70 folds the panel 76 inwardly, and a member 77 and a bar 74 folds the panel 34 to a closed position. An applicator 80 applies an adhesive to the face panel 5 at 48, a device 81 folds the flange 43, 50 against the base panels 5, and pressure rollers 82 compress the flange 43, 50 against the face panel. The box thus formed can then be fitted and the open end of the base closed as above.

Title: Improvements in or relating to methods of preparing aminoketones or their reduction products or salts thereof
IPC: B03C3/51
Filed: 1948-04-14
Abstract: Aminoketones and aminoalcohols, of the general formul <FORM:0640492/IV (b)/1> and <FORM:0640492/IV (b)/2> (wherein R represents hydrogen, acyl, alkyl or aralkyl, and R1 and R2 each represent hydrogen, alkyl or aralkyl or jointly form a ring with the nitrogen atom), and salts thereof, are manufactured by reacting a compound of the formula ROC6H5 with a compound of the formula <FORM:0640492/IV (b)/3> , or a strong inorganic acid salt thereof, in the presence of aluminium chloride and, if desired, hydrochloric acid gas, in a solvent which, apart from the formation of complex compounds, has no interfering reaction with the reacting substances, hydrolysing the product, and, if desired, reducing the resulting aminoketone. The aminoketones may be liberated from their salts by treating a solution thereof with alkali (e.g. ammonia), after adding an alkali metal salt of an aliphatic hydroxycarboxylic acid to keep any aluminium present in solution as a complexion.  When the starting material is an ester or readily decomposable ether of phenol, the ester or ether group may be split during the reaction, whilst if the aminoketones contain unsubstituted or substituted benzyl groups attached to the nitrogen atom or the phenolic atom, these groups may be replaced by hydrogen in the reduction step. In examples: (1) to (4) phenol is reacted with N-methylaminoacetonitrile or its hydrochloride or sulphate in p  nitrobenzene, and 1-(p-hydroxyphenyl)-2-methylaminoethanone is liberated by the action of ammonia in the presence of sodium-potassium tartrate (or an alkali metal lactate or citrate); the tartrate or hydrochloride of the product is hydrogenated in the presence of a nickel or palladium oxide-platinum oxide catalyst to yield the corresponding ethanol; (5) anisole is treated as in (1) to give the same product; (6) phenyl benzoate similarly yields 1 - (p - benzoyloxyphenyl) - 2 - methylaminoethanone (isolated as hydrochloride); (7) aminoacetonitrile hydrochloride is treated as in (1) to produce 1-(p-hydroxyphenyl)-2-aminoethanone and -ethanol; (8) N-isopropylaminoacetonitrile hydrochloride similarly yields 1-(p-hydroxyphenyl) - 2 - isopropylaminoethanone (as hydrochloride); (9) N-methyl-N-benzylaminoacetonitrile similarly yields 1-(p-hydroxyphenyl) - 2 - (N - methylbenzylamino) - ethanone and 1 - (p - hydroxyphenyl) - 2 - methylamino-ethanol.  N - Isopropylaminoacetonitrile is obtainable by reacting isopropylamine hydrochloride with formaldehyde and sodium cyanide in water at 0 DEG C.  N-Methyl-N-benzylaminoacetonitrile is obtainable by reacting methylbenzylamine with formaldehyde-sodium bisulphite and sodium cyanide in cold aqueous solution.
