Title: Improvements in or relating to the stabilisation and refining of cracked hydrocarbon distillates
IPC: C10L1/10
Filed: 1935-07-18
Abstract: Cracked hydrocarbon distillates having an initial boiling point below 65 DEG  C., preferably about 25--55 DEG  C., a boiling range of at least 100 DEG  C., and an end boiling point up to 225 DEG  C., are fractionated to remove the light ends which evaporate under atmospheric storage conditions, and a gum-inhibitor is added.  In an example, the induction period of a gasoline containing 0,02 per cent of tri-cresol as inhibitor was increased from 120 to 300--400 minutes by the preliminary fractionation.  Inhibitors specified are cresols, a -naphthol, guaiacol, pyrocatechol, pyrogallol, phenol ethers, amino compounds, fractions of coal tars and of wood tars.  The cracked gasolines contain di- and triolefines which form gums, and the light ends which are removed have a greater affinity for oxygen than has the inhibitor and adversely affect its action, possibly owing to the presence of butadiene and other low-boiling olefines which may form peroxides and start chain reactions.  The inhibitor is preferably added immediately after the light-end fractionation.

Title: Improvements in the production and treatment of artificial filaments, yarns and similar materials containing organic derivatives of cellulose
IPC: D01F2/28
Filed: 1936-01-24
Abstract: Artificial filaments, foils, films, and similar materials made of organic derivatives of cellulose and containing plasticizers are subjected to stretching in wet steam or hot water at a temperature above 100 DEG  C.  Preferably, the plasticizers used are compatible with the cellulose derivatives in a proportion of at least 50 per cent.  The filaments or foils may be of cellulose acetate, formate, propionate, butyrate, or nitro-acetate, or methyl, ethyl, or butyl cellulose, or ethyl or oxyethyl cellulose acetate.  The plasticizer may be butyl or amyl phthalate, butyl citrate, glyceryl tri-benzoate, tri-phenyl or cresyl phosphate, but is preferably dibutyl or amyl tartrate, dimethyl or ethyl phthalate, di-(methyl or ethyl glycol) phthalate, triethyl citrate, cresyl glyceryl diacetate, methyl cyclohexanyl oxalate, benzyl benzoate, benzyl alcohol, triacetin, triphenyl acetin, or an aromatic sulphonamide.  The plasticizer may be incorporated in a spinning solution or it may be incorporated in the filaments after they have been formed.  Hanks or bobbins may be immersed in aqueous or organic solutions or emulsions of the plasticizer. Stretching may be carried out on hanks or while the materials are travelling, e.g. from the spinning cell to the winding device, and there may be one or more stages of stretching.  The plasticizer may be removed during or after the stretching operation. Water, or aqueous solutions of alcohols, or organic solvents such as benzene toluene, dichlorethylene, carbon tetrachloride, alcohols, or ethers may be used for removing the plasticizer.  In an example, cellulose acetate filaments are formed from a solution containing p-toluene sulphonamide as plasticizer, and passed through a chamber containing wet steam at a temperature above 100 DEG  C., and are simultaneously stretched.  In other examples, diethyl phthalate and triacetin are used as plasticizer.  In another example, cellulose acetate foil containing diethyl phthalate and tri-phenyl phosphate is stretched in wet steam at 105 DEG  C. Specifications 438,584, 438,585, 438,586, 438,587, 438,655, 438,656, 443,707, and 443,773 are referred to.

Title: Screw thread cold-rolling machine
IPC: B21H3/04
Filed: 1960-06-10
Abstract: 893,925. Rolling screw-threads. SOC. INDUSTRIELLE DE DELLE. June 10, 1960 [June 18, 1959; Nov. 17, 1959], No. 20578/60. Class 83 (4). In a machine for cold-rolling screw-threads comprising two threaded rolls mounted on parallel spindles rotating in the same direction at different tangential speeds, at least one of the rolls is mounted on a spindle so as to be capable of slight angular oscillation relative to a plane perpendicular to the spindle and is associated with elastically-yieldable biasing means for returning the roll to a mean position and means are provided for feeding the blanks between the rolls by gravity. To attain the differential tangential speed for moving the blank through the pass, the rolls may differ in diameter or have differing angular speeds of rotation or may have both differing diameters and angular speeds. One of the rolls is adjustable in the plane of the spindles to vary the pass. When a blank enters the pass, under the influence of its own weight, for example, the blank is rolled immediately if the rolls happen to be in phase. If, however, the rolls are not in phase the roll A impresses shallow furrows in the blank, while the roll B tends to slide over the smooth surface of the blank due to insufficient feed pressure until such time as the rolls come into phase at which point the crests of the thread on the roll B enter the furrows formed by the roll A and rolling proper commences. The rolls A, B may be fixed relative to their axes of rotation or if precise screw threads are required provision is made for slight angular movement of one or both of the rolls relative to a plane perpendicular to the spindles. The maximum movement at the periphery corresponds to one pitch of the thread if only one roll is movably mounted; the amount of movement may be halved if both rolls are so mounted. Figs. 7 and 8 show different methods of mounting the rolls A and B for angular movement relative to the plane of rotation. In Fig. 7, spherical seatings 40, 41 attached to the roll-body permit angular movement under the restraint of rubber washers 47, 48 which return the roll to a mean position. Clearances J1-J4 permit the movement. The roll is driven through a pin 39. In Fig. 8, the arrangement is similar but the seatings 40, 41 are replaced by a swivel rollerbearing 56. The rolls are cleaned by brushes 11 and jets of lubricating and cooling oil are directed on to the rolls. Metal screws, wood screws, self-tapping screws, coach screws and worms may be threaded with single or multiple start.

Filed: 1971-04-19
Abstract: 1333672 Colour television WESTERN ELECTRIC CO Inc 19 April 1971 [2 Feb 1970 (2)] 20722/71 Heading H4F A colour television camera having one pickup tube 30, Fig. 3, has a pair of filters 11, 15, Fig. 1, placed in front of the tube. The filter 11 has alternate transparent stripes 12 and opaque-tored stripes 13 and the filter 15 has alternate transparent stripes 16 and opaque-to-blue stripes 17, the breadth of the stripes 13 and 17 in the direction of the line scan of the tube being equal. The output signal of the pick-up tube comprises a baseband portion and a chrominance band comprising red and blue signals each modulated on a carrier, the two carriers having the same frequency but due to the relative angular displacement of the filters 11, 15, the sidebands being interleaved, those of the red signal occurring at multiples of the carrier frequency, and those of the blue signal at odd multiples of half the carrier frequency. The resulting signals are passed to filters 31, 32, Fig. 3. The chrominance signal is separated by comb filters 33, 34, the resulting red and blue signals being subtracted from the baseband portion to give the green signal. In an alternative embodiment, Fig. 4, a vertically striped transparent/opaque-to-red filter is used having opaque-to-blue filters 44 superimposed over alternate stripes in each line scan, the opaque-to-blue filters 44 being displaced by one stripe width in adjacent line scans. Alternatively two identically-dimensioned striped filters, one transparent/opaqueto-red and the other transparent opaqueto-blue may be used, tilted by equal and opposite angles to the direction at right angles to the direction of line scan. In this case a third striped filter, transparent/opaque-to-green may be included, the stripes being at right angles to the direction of line scan and the stripe width being equal to the width in the direction of line scan of the stripes of the other two filters. The camera may be used for independent black and white scenes, the light from which are passed through separate filters of alternately high and low transmission, the resulting images being superimposed on the pick-up tube target. The comb filters 33, 34 comprise two subtractors, a one-line delay line, and two delay lines each of which delays the signal applied to it for the time taken to scan along a line the distance from a point on stripe 17 of Fig. 1, to the point vertically above the corresponding point on the next line scan. For the case of three filters the signals due to three succeeding lines in the filed may be used to derive the red, green, and blue signals or with interlaced scanning two succeeding lines in one field may be used with the interlaced line of the preceding or succeeding field.

Heading G4A. A magnetic drum binary computer stores n words in each drum track, where n is the number of bits in a machine word so that in a multiplication operation n partial products can be formed in a track, each being either the multiplicand or zero, for subsequent accumulation to obtain the final product. The formation of the partial products is effected by the following steps: (1) the test digit (i.e. the least significant digit of the multiplier which has been placed in the accumulator) is copied into all bit positions of the first sector (word). The accumulator is shifted right, and the next digit copied into the second sector, and so on. (So-called group instructions enable this to be done for all multiplier bits with a single instruction), (2) the multiplicand is transferred to the accumulator, and zeros from the multiplicand are copied into the corresponding positions of all partial products (this is in effect a logical AND operation or conjunction between the multiplicand and the words of all 1's or all 0's obtained in (1)). A group instruction is again used to thus complete the formation of the partial products. (3) The accumulator is cleared and the partial products added into it with shift between each addition. The figure shows schematically the main elements of a single-address computer including a drum 1 with 128 storage tracks selected by unit 4 from seven of the address bits, the remaining five bits in 5 controlling the selection of a sector. 16 represents the arithmetic unit and 11-13 the accumulator register, the one-bit stores 12 and 13 being bypassable to allow left or right shift. 15 represents the instruction counter and the normal instruction step involves four phases: (I) Instruction number in 11 incremented by one and sent to address register 5. (II) The instruction is obtained from the drum and the nine function bits are sent to function register 7, the remainder to 15. (III) The address of the operand is transferred from 15 to 5, modified where necessary, where it selects the operand. (IV) Execution of the instruction. The Specification gives the order code of the machine.

Abstract: 410,990. Furnace grates. STEINMULLER, C., and STEINMULLER, L., (trading as STEINMULLER, L. & C.), Gummersbach, Rhineland, Germany. July 26, 1933, No. 21058. Convention date, Dec. 31, 1932. [Class 51 (i).] A furnace grate comprises a number of units which are each composed of a transversely extending stationary damming wall and an associated reciprocable feeder rammer and are separated by transversely extending troughs which are of a considerable size and not varied to any substantial extent by the movements of the feeder rammers, the troughs being adapted to be filled with fuel, during the passage of the fuel over the grate and the feeder rammers b, b<1> adapted to expel the fuel from the troughs along and over the damming walls a, a<1> into the layer of fuel passing above. Only the upper part of the grate, comprising the two uppermost troughs, is shown in Fig. 1. The soles of the troughs c, c<1> are formed by stationary bars e, e<1> and the front walls by movable driving rammers f, f<1>. Smaller auxiliary rammers d, d<1> may be provided between the stationary bars e, e<1> and the feeder rammers. The upper trough is flatter and provided with a closure plate g, the greater depth of the other troughs being obtained partly by the provision of another stationary bar h<1>. The feeder rammers of adjacent troughs are arranged to move in opposite directions. In any one trough the driving rammer moves forwardly as the feeder rammer b moves downwardly. The latter is formed with an inclined top surface ending in a rib i so that as the rammer moves downwardly fuel is crushed between the rib i and the forward face of the driving rammer and forced upwardly as shown by the arrow k. This action is assisted by the auxiliary rammer d which moves forwardly during the last part of the forward movement of the driving rammer. On its upward stroke the feeder rammer thrusts the fuel upwardly into the burning layer above and over the damming wall into the next trough.
