Title: Optimization of gathering systems
IPC: G06G7/122
Filed: 1965-07-26
Abstract: 1,088,716. Computers. MOBIL OIL CORPORATION. July 26, 1965 [Juy 28, 1964], No. 31773/65. Heading G4A. To calculate the most economical gathering point for a plurality of wells, a computer is programmed to first generate a variable function representative of possible positions of the gathering point, then generate a total length function representing the length of pipe required to connect the wells to the gathering point, this function being differentiated so that, as the function representing the position of the gathering point is varied, the position at which a minimum amount of piping is required may be computed. In the form shown, in which more than one gathering point may be used and in which the size of the piping (and hence the cost) varies with the distance of a well from its associated gathering point, difference circuits 903, 904, 906, 907, 909, 910, and root sum square circuits 905, 908, 911, compute the distance of each well from each gathering point, switches αij being closed if the well at the position represented by co-ordinates (x ir , y ir ) is connected to the gathering point (X jp , y jp ). The computed distances are added and, after differentiation, connected to a null circuit to calculate the position which makes the distances minimal. Each distance is multiplied by the appropriate cost function, the costs being added at 920. If, when the gathering points are found, one of the wells is connected to other than its nearest gathering point, the appropriate switches α ij  are adjusted and the above process repeated. This procedure is carried out first with only one gathering point and repeated with the addition of a gathering point at each stage until the number of gathering points giving the lowest cost is calculated. The process may also be carried out with a variable number of processing batteries to which the gathering points are connected, the cost of the interconnecting piping being concurrently computed so that the most economical number of batteries may be determined.

Title: Photographic camera
IPC: G03D9/02
Filed: 1973-07-05
Abstract: 1433601 Self-processing cameras and film units EASTMAN KODAK CO 5 July 1973 [5 July 1972] 32052/73 Headings G2A and G2X A self-processing camera separates, after exposure, the image-recording portion of the selfprocessing film unit from the remaining supporting element which carries the container of processing material by guide means which engage laterally extending lugs on the film unit at its leading end. As shown in Fig. 1, the carrier sheet 16 has a transverse metal stiffening bar 42 whose ends 44 extend laterally beyond the side edges of the sheet 16, and which constitute lugs. A slidable feeder plate 110 has fingers 138 at each end, seen more clearly in Fig. 4 (not shown), and as it slides forward the fingers engage behind the lugs 44 and feed the stiffening bar 42, and hence the film unit, forward into the nip between pressure rollers 112,114. As the container 14 of processing material passes between the rollers, it is ruptured, and the material spread between the sheets of the film unit in known manner. The inherent stiffness of the imagerecording sheet 12 causes it to pass forward after leaving the rollers and out of the camera through an exit slot 134. A pair of guide shoes 144 are mounted on the camera housing adjacent the ends of the rollers, the shoes having arcuate guide surfaces 152. As the film unit passes out from between the rollers, the lugs 44 engage against these guide surfaces, and thus bar 42 is diverted partially round roller 112, as shown in Fig. 8. Bar 42, and hence the carrier sheet 16, which is now waste material, is guided downwards and backwards by guiding surfaces 163 of ramp members 98 into an internal storage compartment 96.

Title: Improvements relating to vertical automatic turning and like machine tools
IPC: B23B9/08
Filed: 1923-12-21
Abstract: 230,569. Ryder & Son, Ltd., T., and Ryder, F. E. Dec. 21, 1923. Boring and turning mills.-A vertical automatic turning or like machine tool comprises an intermitently-rotatable table a carrying a number of chucks e' inclined into positions suitable for the operation of tools fixed in slides supported upon a central column d, in combination with radially-disposed tool-carrying slides 15 supported independently of the column. The movement of the table a is obtained from a belt pulley f fixed to a spindle h h carrying a worm i and a bevel pinion. The worm i engages a worm wheel k having a one-way clutch connection with a boss l keyed to a shaft m. The bevel pinion engages a bevel wheel n to rotate, through gear wheels o and q, a rotatably-mounted wheel p adapted to be engaged by a clutch member r keyed on the shaft m. This shaft carrier a worm s adapted to engage a worm wheel forming part of a cam drum u which is keved to a shaft v. The clutch member r is adapted to slide into and out of engagement with the wheel p by means of a spring-pressed lever 5 provided with an extension 8 engaged by a projection 7 on the cam drum u for disengagement of the clutch r from the wheel p. The clutch is kept disengaged by means of a spring-actuated trip-lever 9 which engages a stop 10 on the extension 8. During this time the cam drum rotates, through the medium of the boss l, at a slow speed until the projection 7 engages with the trip-lever 9. The drum then begins to rotate at a quick speed and gives a partial rotation to the table a through the medium of a cam w on the drum, a rack x, a pinion y, a one-way clutch z, a vertical shaft 1, a spur pinion 2, and an annulus 3 fixed to the table. The table is correctly indexed by means of a tapered plug which is reciprocated by means of a cam on the drum u and engages recesses formed by bushes in the support c and table a. The tool-slides on the column d are actuated by a shaft 34 bevel geared to the shaft v, which carries a drum u<1> in addition to the drum u, each drum being provided with a cam 18 adapted by means of a lever 17, to reciprocate one of the horizontal tool-slides 15. The pulley g through gearing rotates a worm, a worm wheel 12, an annulus 13 and pinions 14, the latter communicating rotation to the work-holding chucks e<1> through clutch members 19, 20. The member 19. has frictional contact with the pinion 14 and the member 20 positive engagement therewith. Each chuck spindle, as it arrives at the loading and unloading position, is stopped by means of a pair of fixed cams 23, 24 which engage a flange on the member 20.

Title: Improvements in or relating to the production of gas mixtures containing carbon monoxide and hydrogen
IPC: C10J3/46
Filed: 1949-12-14
Abstract: In a process for the gasification of solid carbonaceous materials with steam, a fluidized mass is partially gasified with steam in a reaction zone 5 to form coke of high surface area which is withdrawn through the line 11 passing to an impregnating unit 12 where it is impregnated with a catalyst, and is then subjected to a further gasification reaction in a zone 17.  Water <PICT:0672307/III/1> gas is withdrawn from both zones through the line 21 and catalyst containing ash from the zone 17 is rejected through the line 24 or recycled to zones 5 and 17 via lines 23 and 22.  The catalyst may be an alkali or alkaline earth carbonate, preferably sodium or potassium carbonate or zinc chloride and may be applied by spraying the coke with a solution of the catalyst or by condensing on it the volatilized catalyst such that the coke contains 0.1 to 3 per cent by weight of the catalyst.  Temperatures of 1500-2000 DEG F. in zone 5 and 1300-1800 DEG F. in zone 17 are maintained by partial combustion and pressures up to 400 lbs. p.s.i. may be employed.  In a modification the zone 17 is omitted and the impregnated coke is returned to the zone 5.  In a further modification a solution of the catalyst is sprayed directly on the coke in the zone 5.

Filed: 1928-11-05
Abstract: 328,911. British Celanese, Ltd., Dickie, W. A., and Sowter, P. F. C. Nov. 5, 1928. Cellulose esters and ethers, processes for making filaments and films from.-Filaments, threads, ribbons, films, and other products consisting of or containing cellulose derivatives and containing water-soluble salts, e.g. products prepared by the method of Specification 177,868 or 179,234 and containing thiocyanate or zinc chloride, are freed from the soluble salts without loss of lustre by effecting the treatment of the products with aqueous media, e.g. washing, bleaching, or dyeing media, in the presence of lustre-preserving or relustring agents (cf. Specifications 246,879, 259,265 and 259,266). Such agents may be salts, sugars, and solvents or swelling agents for the cellulose derivatives, e.g. sodium chloride or acetate, pctassium or ammonium chloride or sulphate. diacetone alcohol, diethyl tartrate, ethyl lactate and the acetins. Washing with a salt solution is preferably followed by washing with water or with a solution containing a solvent for the cellulose derivative, but washing with a solution containing a solvent or latent solvent for the derivative need not be followed by washing with water. According to the examples, (1) a cellulose acetate thread spun in an aqueous ammonium thiocyanate bath is carried directly into a washing bath comprising an aqueous sodium chloride solution kept in continuous flow, and is then wound in a centrifugal box in which it is washed by a slow stream or a succession of drops of water; (2) a thread spun as in example 1 is wound on perforated bobbins and washed with an aqueous ammonium sulphate solution, the concentration of which is gradually reduced; (3) a thread spun as in example 1 is hanked or wound cm bobbins and immersed until free from thiocyanate in an aqueous solution of diacetone alcohol, the excess of which is afterwards removed. Reference is made also to the treatment of products consisting of or maintaining cellulose formate, propionate, or butyrate, or methyl, ethyl, or benzyl cellulose.
