Abstract: 1,192,671. Printing mechanism. MATH BAUERLE G.m.b.H. 16 Feb., 1968 [17 Feb., 1967], No. 7848/68. Heading B6C. [Also in Division F2] The actions of starting an offset printing machine are carried out in order by mechanisms actuated by cams 7, 25, 26, 17, 10, 13 and 30 or eccentric pins or elements 18, 23 on click-stopped shaft 2 as knob 1 turns it stepwise through increments of 45 degrees. Knob 1 is axially movable on shaft 2, and cam 7, which is fixed to knob 1, may be turned while out of engagement with pin 8 of motor switch 5. By axial movement of knob 1, and with it cam 7, motor switch 5 can, therefore, be disengaged with shaft 2 in any angular position. As shaft 2 is rotated from an off position through seven angularlyspaced positions the following actions are initiated: 0-1. Switch 5 starts the drive motor. 1-3. Inking and clamping apparatus is brought into its operative position. 3-6. An etching roller is brought against a paper plate or a plate cylinder 37 or a dry metal plate or plastics material plate is premoistened. 4-6. An ink application roller 36 is brought into contact with the plate cylinder 37 and the plate cylinder 37 is brought into contact with a blanket cylinder. 6-7. A paper feed mechanism is released. A washing device may be brought into operation to clean the blanket as these operations are reversed in switching off.

Title: Improvements in and relating to electrical relay systems
Inventor: PADDISON ERIC
IPC: H02H3/093
Filed: 1957-03-11
Abstract: 882,436. Protective cut-out arrangements. ENGLISH ELECTRIC CO. Ltd. March. 7, 1958 [March 11, 1957], No. 7918/57. Class 38 (5). [Also in Group XL (c)] A time-lag relay system comprises a timeconstant network consisting of resistance and capacitance in series, means to apply to the network a variable voltage input signal, a biased amplifier providing the relay output and receiving as input the voltage developed across the capacitance and means to inject in series in the amplifier input a voltage varying proportionally with the input signal so that the time of response of the system may decrease more or less rapidly than the reciprocal of the input signal to provide a " more-than-inverse " or " less-than-inverse " characteristic. In an alternative system the time constant network may comprise resistance and inductance in series. In the less-than-inverse time delay overcurrent system of Fig. 1, the input signal is derived from a current transformer 11, a transactor 12 and a rectifier 13 and applied to a potentiometer R2 and the series combination of resistor R1 and capacitor C1 - The resultant signal produced between the potentiometer tapping and the junction between the resistor R1 and capacitor C1 is the voltage developed across the capacitor and in opposition the voltage across the lower part of the potentiometer, the latter voltage being proportional to the input signal. The resultant signal is applied to the base-emitter circuit of a transistor amplifier 15 which becomes conductive when the resultant signal goes positive by an amount approximately equal to the bias provided by the potential drop across a resistor 16 in the emitter circuit of the transistor. The output of the amplifier is obtained from a resistor 19 in the collector circuit and operates a trigger system 20 to cause the tripping of a circuit-breaker 21. In the modification shown in Fig. 2 the voltage developed across the lower part r of the potentiometer R is added to the voltage developed across the capacitor C so that with this modification incorporated in Fig. 1 the relay system would have a more-thaninverse characteristic. A switch may be provided to enable the desired circuit connections to be selected.

Abstract: 307,838. I. G., Farbenindustrie Akt.- Ges. March 14, 1928, [Convention date]. Anthraquoinone vat dyes. - Fast reddish-brown to brownish-black vat dyes are obtained by treating an alpha-amino-1 : 1<1>-anthrimidocarbazole or a derivative thereof with a halogenanthraquinone or derivative thereof. The process is advantageously carried out in a high-boiling organic solvent, such as naphthalene, trichlorbenzene or ethylcarbazole, and in the presence of an acidfixing agent and a catalyst, such as copper or a salt thereof. The dyestuffs separate out during the reaction and can be isolated by direct filtration of the melt, or after previous dilution with pyridine, toluene, an alcohol or the like. Inorganic substances are removed by boiling with dilute nitric acid, and the dyestuffs may be purified, if necessary, by boiling with nitrobenzene or quinoline. In examples, (1) 5 : 5'- diamino-1 : 1<1>-anthrimidocarbazole, obtainable by saponifying the corresponding dibenzoyl compound with sulphuric acid, is heated in naphthalene with 1-p-tolylazimido-3-bromanthraquinone. in the presence of anhydrous potassium acetate, magnesia, and copper; the product dyes cotton in fast, red shades from the vat; (2) 4 : 4<1>-diamino- 1 : 1<1>-anthrimidocarbazole (obtained by heating 4 : 4<1>-dibenzoyldiamino-1 : 1<1>-anthrimidocarbazole with concentrated sulphuric acid to 100-120‹ C.) is heated with 2-chloranthraquinone in nitrobenzene, in the presence of calcined sodium carbonate and copper bronze; the product dyes cotton in corinth shades; and (3) 5-amino-41- benzoylanimo-1 : 1<1>-anthrimidocarbazole. obtainable by partial saponification with sulphuric acid of 5: 4'-dibenzoylamino - 1 : 1<1>-anthrimidocarbazole (Specification 307,306), is heated in naphthalene with 1-benzoylamino-4-chloranthraquinone, in the presence of anhydrous potassium acetate, magnesia and copper powder; the product dyes cotton in blackish-brown shades.

Filed: 1941-07-10
Abstract: 548,841. Sparking plugs. AC-SPHINX SPARKING PLUG CO., Ltd., and BARRING- TON, R. R. July 10, 1941, Nos. 8692 and 8693. [Class 7 (iv)] [Also in Groups XXXVI and V] A resistance element is made by mixing finely divided conductive refractory material, such as silicon carbide, with a finely divided metallic conductor and a glassy bonding element, the percentage of the metallic conductor being sufficient to prevent a gradual increase of resistance and insufficient to cause increase in conductivity. The preferred metallic conductor is copper and forms from 5-10 per cent. of the whole mixture. In an example 18 per cent. of very finely divided copper is mixed with 18 per cent. of equally finely divided dehydrated boric acid. These are ground together and then mixed with 64 per cent. of finely divided silicon carbide. The mass is compacted to the desired shape and heated to about 800‹C., the mixture being sealed from the atmosphere to prevent oxidation of the metal. Metal contacts may be provided on the container or in the sealing materials. The resistance may be incorporated in a spark plug as shown.' Within the outer shell a is the insulator c having a bore which contains at its lower end an electrode d. On top of this is a small pellet of ground mixture e of copper (55 per cent.) and a borosilicate glass (45 per cent.) bonded with dextrine. A small copper disc f is then pressed down on to the pellet and on top of that is placed a mixture g of powdered silicon carbide (64 per cent.) powdered copper (18 per cent.) and dehydrated boric acid (18 per cent.). A further copper disc h is then pressed on to the resistance mixture and covered by a further pellet i of a ground mixture of equal parts of copper powder and a glass of low melting point. The whole mass is then compressed by the screwed centre conductor j  and heated to 900‹C. Alternatively the resistance element may be preformed and sealed, and more than one such element may be combined serially with several glass seals. Other carbides such as those of boron and tungsten may be used instead of silicon carbide.

Abstract: 228,743. Foster, J. Y., Foster, J. H., Foster, F., Hornby, J. S., and Wilkinson, M. L. April 7, 1924. Printing-surfaces. - Relates to devices for clamping stereotype plates on cylinders wherein each clamping-jaw is slidably mounted on a spindle having lugs thereon over which the jaw normally can slide but which, when the spindle is rotated through a right-angle, prevent endwise movement of the jaw, and, when the spindle is subsequently moved axially, cause the jaw to be moved with it to clamp the plate, and consists of an arrangement whereby the spindle is given the desired turning and axial movements by a single device. The clamping-member 11 is of ring form having a bevelled face to engage the plate edge and provided with guide blocks 12 slidable on rotatable spindles 13 mounted in recesses 14 in the cylinder end. Each block 12 has a hole 20 and each spindle has lugs 19 similarly shaped so that while normally the block can slide along the spindle, by turning the spindle through a right-angle, the lugs prevent movement of the block relative to the spindle. A toothed wheel 15, journaled in a plate 16 spaced from the cylinder end, has a screwed bore with which engages the threaded end of the spindle 13. A coil spring 18 extends between the wheel 15 and a collar 17 on the spindle 13, and serves as a friction coupling between the wheel and spindle when the wheel is turned, until further rotation of the spindle is prevented by stops 17<a> on the collar 17. In this position of the spindle 13 the lugs 19 are in position to hold the member 11 against the printing-plate. Further turning of the wheel 15 causes the clamping-member and spindle to move bodily to complete the clamping action. Instead of the clamping-member being of ring form, separate clamping-dogs may be used, the spindles of which may 'be operable independently or be geared together.
