Title: Preparation of carbon black
IPC: C09C1/54
Filed: 1961-11-17
Abstract: Carbon black is prepared by thermally decomposing a hydrocarbon fluid (e.g. methane, butane, pentane, gas oils, kerosene, gasoline boiling range hydrocarbons, heavy or light naphthas, or residual or recycle oils) in the presence of finely divided coal coke or charcoal, whereby the carbon black thus produced has a rubber property of modulus lower than that of a carbon black produced in the absence of the finely divided material.  The hydrocarbon fuel may be natural gas or one of the above fluids, and the combustion supporting gas may be air, oxygen-enriched air, or oxygen.  The solid material may have a particle size of 100% minus 200 mesh U.S. Sieve Series, and may be injected separately into the reactor or introduced with one or more of the reactant streams. In Examples 1 to 5, five hydrocarbon feedstocks of specified analysis are reacted to form carbon black, several runs being conducted for each feedstock and one being a blank conducted in the absence of solid material.  The solid material used is powdered bituminous coal of specified analysis of 200-300 mesh U.S. Sieve Series and is suspended in the feed stock. The blacks produced are compounded with styrenebutadiene rubber and customary ingredients, and a table showing modulus, tensile strength at break, elongation at break, and oil factor is given. In Example 6, anthracite or charcoal introduced with the air is employed. In Example 7, another bituminous coal is used, and the blacks produced are compounded with natural rubber, pine tar and customary ingredients, tensile data being given.  In Example 8, petroleum coke or coal coke are used, while in Examples 9 and 10 varying amounts of bituminous coal are employed.  In Example 11, bituminous coal or lignite are used.ALSO:The modules of carbon black-containing natural and synthetic rubber vulcanizates is lowered by using therein carbon blacks obtained by thermally decomposing a fluid hydrocarbon feedstock in the presence of finely divided coal, coke or charcoal (see Division C1). The examples describe the use of such carbon blacks in otherwise conventional recipes for the vulcanization of a butadiene-styrene rubber and natural rubber.

Title: Mark detection apparatus
IPC: H05K3/00
Filed: 1974-10-04
Abstract: 1518093 Detecting marks MULLARD Ltd 30 July 1974 [4 Oct 1974] 43136/74 Heading G1A The presence of a mark within a field of view is detected by photo-electrically analyzing the field by dividing it into regularly spaced rows 10 and columns 11, of notional picture elements, selecting any one of these elements as a test centre element 9, comparing its brightness with that of selected picture elements in the eight straight lines of picture elements lying along the row and column and the diagonals intersecting at the centre element, the number of selected picture elements being the same in each line, and means for producing a mark detection signal if at least one selected picture element in each of the lines meets the condition that it differs in brightness from that of the centre element by at least a predetermined threshold amount of the same sign for each line. The mark may be on a workpiece and is located to effect alignment thereof with a tool. Alternatively it may be a flaw in sheet material or a positional reference mark on a sheet. The picture elements may be derived from a television camera. Rows 10 of the matrix are derived from regularly spaced samples of video output along the lines of the T.V. raster and columns 11 from corresponding samples in successive lines. The square of picture elements of Fig. 1 cannot respond to a three picture-element mark, if another mark is too close and thus covers one of the other picture elements 1-8 Fig. 4 (not shown). In this case an extended arrangement of operative picture elements is used, of the general form of Fig. 5 (not shown), and in particular with 16 elements surrounding the central operative element, Fig. 6 (not shown). For certain shapes of marks, the lines of picture elements radiating from the central operative element may have the first one or first two inoperative. Also the response signal may only be generated if the intensity at more than one operative element in each radial line differs by the required threshold. The intensity levels at the picture elements may be digitized into 5-bit binary codes defining 32 levels, for the purpose of utilizing an operative pattern as illustrated in Fig. 1. In the arrangement of Fig. 9, the picture is scanned in 64 vertical columns each of 64 picture elements, each element being digitized in this way and supplied on 5 parallel lines to shift register sequence 31-36. In this way after a five column scan, the bottom five stages of the five registers store the intensity values corresponding to a five-by-five array of picture elements in the top left hand corner of the picture. The values for operative element values 1-8 can be read out and compared by subtraction circuits 50-57 with that of the central element 1, to determine if the required condition has been satisfied to indicate the presence of a mark.
