Title: Improvements in or relating to the manufacture of printing inks
IPC: C09D11/02
Filed: 1924-03-13
Abstract: 236,614. Shuck, Maclean & Co., Ltd., and Price, W. P. March 13, 1924. Ink.-In order to avoid the necessity for the use of damping-apparatus in lithographic and like printing-processes, printing-ink is mixed with an emulsion of the water-in-oil type formed with an aqueous solution of a salt or salts which are capable, either alone or with the aid of an emulsifying-agent, of forming such an emulsion, which are deliquescent, and which have no deleterious action on the pigments. The emulsion is preferably first formed with the solution and lithographic varnish and is subsequently incorporated with the ink. Suitable emulsions are formed from stated proportions of calcium chloride solution, varnish, petroleum jelly, and ammonium chloride or borax. The ammonium chloride or borax is dissolved in the calcium chloride solution and emulsified with the other constituents, different amounts, varying according to the consistency of the ink, being added to the ink. Alternatively, the solution may be emulsified with the ink, oil being added during the process if necessary. Materials to impart or counteract acidity or alkalinity may be added.

Filed: 1968-02-10
Abstract: 1,199,662. Knitting - machines. ELITEXZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI. 10 Feb., 1968, No. 6699/68. Heading D1C. Needle selection is achieved on a circular machine by pivoting jacks outwardly under the influence of a controlled electromagnet so as to cause the jack butts to engage the associated cam and thereby be raised to cause projection of the corresponding needles. The gap in the camway at the point of selection is of a width such that only one jack can be moved outwardly under the influence of the electromagnet at any one time, Fig. 4. The butts may engage the camway in either direction of movement in which case the gap may have edges sloping in either direction Fig. 5. Alternatively the jacks may be pivoted such that an upper butt is withdrawn from engagement with a camway leaving a lower butt uninfluenced to continue in a path in which it is subsequently elevated to raise the corresponding needle.

Title: Improvements in and relating to systems controlling the sequential actuation of electrically operated soot blowers
IPC: F28G15/00
Filed: 1937-03-08
Abstract: 491,915. Control of several motors. BRITISH THOMSON-HOUSTON CO., Ltd., BOURNE, S. N., and JEFFERSON, H. F. March 8, 1937, No. 6825. [Class 38 (iii)] Travelling to predetermined limits.-In an electrically operated soot blower the sequential actuation of the several blower heads is controlled by a sequence switch including a movable contact operated by a relay, the control circuits including switches controlled by the respective blower heads and effective to maintain the energizing connections at the commencement of the operation of a blower head, and for disconnecting the energized circuit and establishing energizing connections for the next blower head at the completion of the operation. With hand switches 30, 31, in the position shown operation of a starter button 34 energizes a self-maintaining relay 35 to energize a contactor 37 and start a motor operating the first head 24. The initial movement of the head closes a switch 38. A relay 39 closes and a coil 40 is energized to operate a pawl reciprocated by a motor 41 into engagement with a ratchet wheel on a spindle of a sequence switch whereby this switch moves from contacts 24a associated with the first head to contacts 25a associated with the next head 25. As the contacts 24a are left, the relay 39 is de-energized and the motion of the sequence switch is stopped. Additional manually-operated switches 72 may be provided in case of the relays 39 sticking. A centrifugal switch 42 controls a lamp 43 and an audible alarm 46, to give indications if the operation of the motor stops. A switch 47 is operated to reverse the motor between limits of travel and at each reciprocation a ratchet 50 is operated, and after a predetermined number of reciprocations, a switch 49 is opened to stop the operation of the first head. The relay 35 is de-energized to open the contactor 37, and contacts on the relay 35 effect closure of a relay 56 to initiate a similar operation of the next head. Similar control is then effected for each of the remaining heads. In the case of heads 27, 28 and 29, which are of the type not inserted and retracted for operation, the control is effected by a contactor 59, and a switch 61 closed when the head commences to operate, and opened after a predetermined number of revolutions. The switch 61 is opened by means of a star-wheel 65, stepped by rotation of the motor. Further contacts 67, 68, 69 are provided on the sequence switch connected together and acting as blank contacts for use when additional heads are to be controlled. The operation of any particular head may be omitted by moving a corresponding switch 31 to its closed position, and to operate any individual head, a switch 71 is operated after movement of the switch 30 to its hand position. Further description is given with reference to simplified diagrams, Figs. 1 and 2 (not shown). Specification 491,916, [Group XXVIII], is referred to.
Patent GB-374134-A (GB)
Title: New manufacture of cyclic ethers
Filed: 1931-03-05
Abstract: Cyclic ethers are obtained by reacting di- or polyhalogenated ethers, having at least one halogen atom in each radicle, with metallic oxides.  b b <1>-dichlordialkyl ethers such as b b <1>-dichlordiethyl ether or b b <1>-dichlordipropyl ether are preferably used as starting materials, but other halogenated ethers, including bromo-or iodo- or mixed derivatives, polyhalogenated ethers, and a a <1>- or a b <1>-derivatives, for example, a a <1>-dibromdimethyl ether, a a <1>-dichlordimethyl ether, or chlormethyl-b -chlorethyl ether, may also be employed.  Suitable metallic oxides are those with a relatively low affinity for oxygen, for example, litharge, mercuric, cupric, or silver oxides. Carriers such as pumice or asbestos may be used.  The oxide may be employed in solid form, or dissolved or dispersed in a suitable medium.  The ether may constitute the solvent liquid, or may itself be dissolved in solvents such as benzene, toluene, xylene, benzine, chloroform, or carbon tetrachloride, or may be dispersed in a non-solvent liquid.  The product of the reaction may be soluble in the liquid medium employed, as in the production of dioxane by reacting b b <1>-dichlordiethyl ethers with finely divided copper oxide or lead oxide in the presence of a solvent for dioxane, such as any of the above solvents or suitable mixtures thereof.  The reaction may be carried out in the absence of water or other hydrolysing media, for example, in the presence of inert or non-polar liquids.  The reaction may also be effected without the addition of a liquid medium, when treating the metallic oxide with the halogenated ether either in the liquid or vapour state.  The process may or may not be continuous.  The reaction temperatures and pressures depend on the product sought, for example, in the production of dioxane temperatures between 100 and 170 DEG  C. under atmospheric pressure may be employed.  Examples are given.

Filed: 1969-02-11
Abstract: 1,224,431. Selective signalling. RELIANCE ELECTRIC & ENG. CO. 11 Feb., 1969 [26 Feb., 1968], No. 7429/69. Heading G4H. A computing weighing scale includes a circuit for checking that the unit price entered into the system corresponds with the positions of the unit price print wheels set by the computer when it has multiplied the unit price by one. The unit price is either entered manually on switches in decimal form or automatically from a commodity identity printing plate having binary coded apertures representing the unit price. The printing plates have interlock apertures which prevent a manual imput being effective when a coded price printing plate has been inserted. The computer multiplier is almost identical to that of Specification 1,081,538. An additional interlock consists in interrupting the computation and transferring the unit price input to manual control if the lamp illuminating a coded printing plate fails. The computer provides commands for followup print wheel positioning systems for the cost and unit price digits, the feedback commutator in the unit price systems providing outputs for comparison with the manual or automatic unit price inputs.

Title: Method and apparatus for indicating and controlling the rate of heating of a travelling strip
IPC: G05D23/19
Filed: 1957-03-06
Abstract: 853,484. Electric correspondence control systems. UNITED STATES STEEL CORPORATION. March 6, 1957 [Nov. 15, 1956], No. 7433/57. Class 40 (1). [Also in Group XXXV] Apparatus for indicating the rate at which a travelling metal strip S is electrically heated comprises a wattmeter 26 for measuring the heating power, the position of whose pointer 36 is repeated by a balanced potentiometric system, the voltage across the transmitting potentiometer 32 being modified in accordance with the width of the strip by a potentiometer 40, and the voltage across the receiving potentiometer 48 being the output of a tacho-generator 58 modified by a potentiometer 54 in accordance with the thickness of the strip. A scale 52 is associated with potentiometer 48 so that the position of the slider 50 indicates the watts consumed per pound of strip. The heating current supplied between rolls 6, 10 is obtained from transformer 14 and controlled by a saturable reactor 16 in series with the primary winding, the control current through winding 18 being obtained from a generator 20 whose field current is controlled by rheostat 22, either manually or automatically. To control the heating rate automatically at a -given value limit switches 66, 68 are adjusted on either side of the given value on scale 52, and slider 50 carries a moving contact 70 to close the energization circuit for a motor 24 when one of the limit switches is operated, thus altering the value of rheostat 22 until the desired heating rate is attained, and slide 50 is located between contacts 66, 68. The apparatus is used for measuring and controlling the heating of a tin-coated steel strip to melt the tin and improve the surface properties. The heating rate is said to be indicative of the approximate tin-iron alloy layer thickness. Specifications 596,854 and 596,856 are referred to.

Title: Improvements in or relating to ammonia separation process
IPC: C10K1/10
Filed: 1955-03-15
Abstract: <PICT:0791437/III/1> Ammonia is separated from an ammonia-containing gas by scrubbing with an aqueous solution of an amine complex salt of nickel, cobalt, copper, zinc, or cadmium containing less than 4 co-ordinated ammonia groups for each metal atom and having an equimolar proportion of ammonia as an ammonium salt of a strong inorganic acid dissolved therein, and heating the resulting ammonia-enriched solution to recover ammonia gas.  The gas passes into first absorber 10, and on to second absorber 11, and ammonia-free gases are withdrawn at 14.  The metal diamine salt solution is passed into the second absorber 11 at a temperature to maintain an equilibrium temperature of 70 DEG  C. at the exit for the countercurrent of gas at 14.  The solution passes through heater 16 to first packed absorber tower 10 at a temperature to maintain an equilibrium temperature of 97 DEG  C. at the base of the tower. The metal tetramine salt solution formed is passed from 18 to stripper 12, where the diamine is regenerated with steam, and the resulting solution returned through cooler 13 to second absorber. The metal and ammonium salts may be halides, or nitrates, but the preferred solutions contain metal sulphate in concentration 30-125 grms. of metal/l., and ammonium sulphate in amount 1-2 mols./l.  The absorbing solution may be heated beyond the diamine stage with precipitation of metal hydroxide, basic metal salt, or metal ammonium double salt, which permits increased absorption, when recycled as a slurry, or dispersion in the amine solution. When a single absorber is used the solution should be recycled through the absorber until exhausted. The process is particularly suitable for separating ammonia from carbon dioxide.

Filed: 1940-04-29
Abstract: 540,798. Forming yarns containing staple fibre from continuous filaments. BRITISH CELANESE, Ltd. April 29, 1940, No. 7621. Convention date, April 27, 1939. [Classes 120 (ii) and 120 (iii)] Apparatus for forming yarns containing staple fibre from continuous filaments comprises a twisting device, means for taking-up the yarn above the twisting device a movable severing roller over which the yarn passes to the take-up means, a roller for pressing the filaments continuously against the surface of the severing roller and means for breaking the yarn at a point below the severing roller when it breaks at at a point above the severing roller. As shown the continuous filament yarn 2 from an up-twisting device 3 passes through a guide 6, over the positivelydriven spirally fluted, severing roller 8 on to which it is pressed by a spirally-fluted roller 9 slidably mounted in grooves 13 in brackets 14, to the takeup device 23 where the staple-fibre yarn is laid on the rotating bobbin 21 by a traversing-guide 18. Before passing to the guide 18 the yarn passes over a hinged bail 15 having a hooked portion 25 engaging a loop 26 in a pivoted finger 27 so that if the yarn should break above the severing roller, the bail falls and moves the finger 27 into the path of the balloon 29 of the yarn and breaks the supply to the severing roller. The severing roller moves with a peripheral speed less than that of the take-up device.
