Abstract: 583,324. Printing-machines. JENNINGS, H. W. K. (Addressograph-Multigraph Corporation). Oct. 17, 1944, No. 20089. [Classes 100 (i) and 100 (ii)] Addressing and like machines; sheet registering devices. In a printing-machine in which printing-devices are fed in succession to printing position, sheets to be printed are fed along a guideway to a printing position at which they are brought to rest in succession, and a secondary or proof sheet is fed step-by-step across the printing position and above the path of the primary sheets by means disposed at one side of the guideway, simultaneous impressions being printed on the primary and secondary sheets by means of carbon or like material interposed between the two sheets. Fig. 2 shows a plan of a machine in which address-plates D are fed from a magazine M to printing position beneath an impression head P, pre-printed sheets 42, such as cheques 'are fed from a hopper 50 along a guideway G to printing position and then to a receiver 80, and a list-strip 44 is fed at right angles to the path of the sheets 42. The latter are separated by a device 51 and are fed by an endless belt 54. Each time the separator releases a sheet, a bar 66 reciprocated therefrom turns a ratchet which rocks a cam on a shaft 60 adopted to raise and lower a stop 68, Fig. 3, working in a guide 69 in a table top T. The list-sheet normally lies above the sheet-guide and is pressed down on to the sheet by the impression mechanism. A linkage 78, 76, 72 by which the shaft 60 operates the stop 68 is so arranged as to allow a wide list-sheet to be used. A side member 62<1>, Fig. 2, of the sheet-feed device is cut away at 91 to allow the list-feed device to lie close to the machine table. The sheet-feed device is driven by a separate motor which is cut out when a predetermined number of impressions has been printed. The machine may print other variable matter, such as a number or signature, on the cheques and list-sheet. Specifications 341,339, 409,779, 489,390, 558,793, 560,597 and 583,323 are referred to.

Title: Improvements in or relating to printing telegraph exchange systems
IPC: H04L12/00
Filed: 1939-07-11
Abstract: 531,902. Telegraph exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (Clemens, P. J.). July 11, 1939, No. 20210. [Class 40 (iii)] In a teleprinter exchange system, the repeaters are provided in the manual or automatic connecting circuit and are automatically modified in accordance with the character of the calling or called line with which connection is made. Fig. 1 shows lines T1, T3 arranged for single-current operation and lines T2, T4 for double-current operation; the lines being connected differently to the contacts of the finders LF and selectors S. Where connection is made with a single-current line T1, relay AR is energized over its left-hand winding which overcomes the right-hand winding in circuit with a compensating resistance BN1. Interruptions in the line circuit at T1 are repeated at ar1 to line T3, say. When connection is made with a double-current line T2, relay CR is energized and its contacts cr1, cr2, cr3 alter the circuits in such a way that the transmitting leg is connected over brush a to relay AR, and the receiving leg over brush b to the armature of repeating relay BR. Similarly if connection is made to a double-current line T4, relay DR is energized and makes similar changes in the circuits. In a manual system (Fig. 2, not shown) the relays corresponding to CR, DR are energized over the sleeves of the jacks of doublecurrent lines only. In modified automatic systems, (1) the compensating resistance is in a circuit individual to the line instead of in the connecting circuit (Fig. 3, not shown), (2) the relay corresponding to DR is energized over a circuit of the register-controller (Fig., 4, not shown), and (3) a different form of repeater is used (Fig. 5, not shown). Specification 510,306 is referred to.

Title: Method of forming fibrous aggregates
IPC: B01J2/00
Filed: 1968-04-29
Abstract: 1,235,487. Agitating fibrous suspensions. SOC. D'EXPLOITATION DES BREVETS GRANOFIBRE-SEBREG. 29 April, 1968 [27 April, 1967; 13 Nov., 1967], No. 20280/68. Heading B1C. [Also in Divisions Dl and D2] Fibres are formed into generally spherical aggregates by placing them in suspension in a liquid, subjecting the suspension to a rotational movement so that the fibres circulate and tumble and tend to cling to one another, and also subjecting the suspension to a pulsatory movement to produce ebb and flow waves in the suspension. Preferably the two movements are in the same direction, and the frequency of the pulsatory movement is equal to or a multiple of that of the rotational movement. As shown the vessel 1 has a partcylindrical lower surface 5, and a cylindrical but eccentrically mounted rotor within it. Rotation of the rotor imparts rotational shear and also a pulsatory movement to the suspension 4. If spaces are left between the ends of the rotor and the ends of the vessel (fig. 2, not shown) there is also a circulatory movement along the vessel. The suspension enters at 17 and leaves at 16 at the crest of each pulsation. A series of these vessels may be placed in cascade. In other embodiments, the rotor is frusto conical, elliptical or curvilinearly triangular, or vertically mounted in a cylindrical vessel. In others: (figs. 3 and 4, not shown) a hollow cylinder is mounted inside and fast to the rotor, and adjustable ports (27, 28) are provided to admit suspension from the vessel into the hollow cylinder and to lead it away from the other end of the hollow cylinder, agitators in the form of eccentric cylinders (45, 46) being also provided; (figs. 5-7, not shown) two vessels as in fig. 3 are mounted side by side, the wall between them being low enough to allow the suspension from one to pass into the other at the crest of its pulsation (the pulsations in the two vessels may be in or out of phase or in quadrature), the suspension is led first into the inside of the first hollow cylinder, then through the first and second vessels to the inside of the second hollow cylinder and out; (fig. 8, not shown) a similar apparatus is arranged so that the suspension enters the two vessels and passes from them into the two hollow cylinders and out; (figs. 9 and 10, not shown) three vessels with three rotors are mounted side by side with low walls between them, all three have rotors, the first and last of which have hollow cylinders in them, but the middle one has not, the suspension is admitted to the inside of the first cylinder, passes through the three vessels in succession, and leaves through the last cylinder; and (fig. 11, not shown) fibres from a fibre-forming apparatus are fed to a mixing vessel for the suspension, then either to a cascade of single vessels of the type shown or of fig. 3 (not shown), or to at least one apparatus of the two- or three-vessel type, then to a separating and grading apparatus, a draining apparatus and a drying apparatus.

They may be obtained by coupling simultaneously or successively 2 mols. of the same or different aromatic diazo compounds of which at least one contains at least one group of the formula <FORM:1103513/C4-C5/2> or <FORM:1103513/C4-C5/3> wherein Y is a halogen atom, the radical of a polybasic inorganic acid or an -OH group, with coupling components of the general formula <FORM:1103513/C4-C5/4> wherein Ar represents a benzene or naphthalene radical containing at least one -SO3H group, R1 represents an H atom or an acyl group and, when using coupling components in which R1 is an acyl group, the second mole of diazo compound is not coupled until the acyl radical has been split off by saponification, whereupon, in the disazo dyes obtained which contain a hydroxyl group in Formula (1), the hydroxy group is treated with polybasic inorganic acids, their monoamides or monochlorides to esterify the alcoholic OH group; and, if desired, the dyestuffs are treated obtained with agents yielding metal. Monoazo dyes may be metallized, coupled to form disazo dyes and which may then be treated with another agent yielding metal to give disazo dyes containing different complex-bound metals. A second hydroxy group which is in o1-position to an o-hydroxyazo group may be introduced by oxydative coppering. Examples are given for the production of the dyes. The dyes are useful for dyeing or printing natural or regenerated cellulosic materials, wool, silk, or polyamide fibres.ALSO:1 - Hydroxy - 8 - acetoacetylamino - naphthalene -3:6-disulphonic acid is prepared by neutralizing 1 - hydroxy - 8 - aminonaphthalene-3:6-disulphonic acid with anhydrous sodium carbonate, and then adding diketene until a free amino group can no longer be detected. The compound is useful as a coupling component in the preparation of dyestuffs (see Division C4).
