Abstract: 1300064 Boots &c SHOE & ALLIED TRADES RESEARCH ASSOCIATION 19 April 1971 [20 Nov 1969] 56882/69 Heading A3B [Also in Division B5] In a method of cutting out shoe uppers by heating blanks along the line to be cut, a material more susceptible to heating by high frequency energy than the material of the blank adjacent where the cut is to be made, is provided on or in the blank along the line to be cut, and the blank is subjected to high frequency energy to heat the more susceptible material sufficiently to effect the cut. The blank is positioned between electrodes for radio frequency dielectric heating, placed in a waveguide for micrawave heating, or heated inductively. As described, shoe uppers are cut from homogeneous, poromeric, stretchable, thermoplastic sheet material, which is transparent to high frequency energy, using carbon as the material more susceptible to radio frequency heating; alternative more susceptible materials are nitrocellulose, or iron filings with a binder. A single, or a pattern of cutting lines may be parked by impregnating into, or printing on, the blank, which may be nylon. In a continuous process, roll material passes through a printing or marking machine and then through the high frequency heating device.

A process for producing a textured fibre assembly comprises drawing an extruded foamed thermoplastic material and subjecting the drawn material to forcers e.g. rubbing, rolling, beating, twisting or shaking, to break down the foam walls and produce a threedimensional structure of fibre elements as described in Specification No. 1,114,151, the structure thus obtained is then treated so that a proportion of fibre elements adopt an inclined attitude, i.e. inclined to the direction of drawing when the assembly has been tensioned and allowed to relax on a horizontal surface. The treatment may comprise crimping, shrinking or swelling, the fibre elements preferably being composed of thermoplastic polymers which react differently to the treatment. The fibre assembly may be in the form of a non-woven fabric or preferably in the form of a yarn. In the case of the treatment being a crimping treatment, this may be effected by compression, false-twist, knit-de-knit, techniques or by means of knurled wheels.

Title: Improvements relating to the correction of stored data
IPC: G06V10/30
Filed: 1969-12-05
Abstract: 1,243,978. Pattern correcting. C.I.T.- COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 5 Dec., 1969 [12 Dec., 1968], No. 59440/69. Heading G4R. An arrangement for correcting line-pattern data stored as a matrix array of logic signals detects sequences of the same logic signal value by passing the stored data successively through detection windows each constituted by a group of matrix positions and defining a direction on the pattern, selects one of the directions in accordance with the sequences detected, passes the stored data through a correction window constituted by a group of matrix positions and having the selected direction, and applies correction signals to the data passing through the correction window to compensate deviations of the pattern direction from the selected direction. A fingerprint or other pattern is stored in a matrix having a shift register as each row, the matrix being shifted downwards slowly and each register being shifted in a loop relatively quickly, during which logic circuits detect horizontal, vertical, right diagonal and left diagonal sequences of black or white bits (with single lateral deviations at an end permitted). These sequences are roughly centred on a common bit position. Further logic circuits detect a horizontal sequence of black or white bits (with single lateral deviations at an end permitted) further down the matrix. Five counters, reset at the end of the rapid horizontal shifting of the matrix, count detections of the above five categories of sequences respectively (no distinction being made between black and white sequences). Each counter exceeding a threshold selects a correction window with the corresponding direction(the horizontal window will only be selected if both the respective counters exceed their thresholds). Alternatively, the counter with the highest count could be taken. The correction windows involve logic circuits which sense sequences of bit positions (some broken) in the respective directions, all roughly centred on a common bit position, to deduce the correct value for that position. The selected correction window or windows control two leads causing resetting of the bit position to 1 or 0. If both leads carry a signal (due to two or more windows being selected and giving contradictory orders) no correction is made.

Abstract: 1,207,256. Hydrogenating hydrocarbon oils. CITIES SERVICE RESEARCH & DEVELOPMENT CO. 16 Dec., 1968 [19 Dec., 1967], No. 59628/68. Heading C5E. In a process for hydrogenating heavy hydrocarbon oil under high pressure and temperature to produce a gas stream and a high boiling liquid hydrocarbon stream at high pressure and temperature containing polymerizable constituents, polymerization is reduced by reducing the pressure of the liquid stream to a pressure of up to about 200 p.s.i.g., and before, during or immediately after the reduction of pressure, contacting the stream with a cool liquid hydrocarbon stream to reduce the temperature of the hot stream to not more than about 650‹ F., and preferably about 550‹ F. The cool stream may be a light cycle oil condensed from the gas stream, and may be divided into two streams, either or both of which may be delivered to the hot stream, one of the cool streams being first used to preheat the feedstock. The mixed hot and cool streams, after further cooling, may be mixed with the condensed effluent stream from the hydrogenation zone.

Abstract: 1338612 Cracking and reforming naphtha UNIVERSAL OIL PRODUCTS CO 16 Dec 1970 [17 Dec 1969] 59689/70 Heading C5E An aromatic gasoline and saturated and unsaturated hydrocarbons having three or four carbon atoms in the molecule are made from a feedstock comprising both alkanes and naphthenes boiling in the range 82 to 204 C. by first reforming the feed under conditions to convert more than 80% of the naphthenes but less than 40% of the alkanes to aromatics, then separating the product into an aromatic gasoline stream and a saturated hydrocarbon stream by solvent extraction and finally cracking the saturated stream in a fluidized bed of catalyst without added hydrogen. The hydrocarbons of three or four carbon atoms may be used to make alkylate gasoline, or hydrolysed to alcohols or converted to amines, esters, ethers or ketones, all of which can be used as gasoline components. Suitable feedstocks are straight-run gasoline, natural gasolines, and thermally or catalytically cracked gasolines, and may be of full boiling range, or higher-boiling fractions only. Catalysts for the reforming step comprise carriers such as alumina, faujasite, mordenite or combinations of these and a reactive metal component such as Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, Pt or Re and may also contain a combined halogen. The catalyst may be fluidized or otherwise moving, but is preferably in a fixed bed. Catalysts for the cracking step are silica-alumina, silica-magnesia, silica-zirconia and zeolites, natural or synthetic, and may be compounded by ion-exchange or impregnation with alkali metals, alkaline-earth metals, rare-earth metals or metals of Group VIII. As shown, feed in line 20 and hydrogen in line 21 pass to reforming at 15. The reformate is fractionated at 16 to give a hydrogen-rich gas stream 23, a stream 24 of hydrocarbons up to C 4 , a stream 25 of C 5  and C 6  hydrocarbons and a stream 26 of heavier hydrocarbons. Stream 26 is or streams 25 and 26 are extracted by a solvent at 17, and the aromatic extract taken off at 28. The raffinate in line 27 is cracked at 18 and fractionated at 19 to give cracked gasoline 31 and light hydrocarbons (C 3  and C 4 ) 30. The cracked gasoline can be recycled by line 33.
