Title: Improvements in or relating to lithographic printing machines
Inventor: MCDONALD ANGUS ALEXANDRA
IPC: B41F7/26
Filed: 1961-11-30
Abstract: 957,533. Printing apparatus. METAL BOX CO. Ltd. Aug. 17, 1962 [Nov. 30, 1961], No. 42947/61. Heading B6C. A lithographic plate on the printing cylinder 37, Fig. 2, of a rotary machine is dampened by wetting liquid exuding from the absorbent cover 35 of a rotating hollow damping cylinder 1 which has a porous peripheral wall and is mounted on a partially hollow rotating shaft 3, Fig. 1, to which the wetting liquid is supplied from a reservoir 12 through a feed line 13. Liquid issuing from the axial bore 7 of the shaft 3 is distributed throughout the interior of the cylinder 1 by a perforated tube 9 axially coincident with the shaft. The reservoir 12 comprises compartments 14 and 15, the former containing the wetting liquid and having a stoppered and filtered liquid filling opening 17, whilst the latter is associated with a spring- loaded air-pressure control valve 26. The liquid from the compartment 14 is forced into the cylinder 1, and from thence through the peripheral wall and the covering, by increasing the air pressure in the reservoir through pumping air into the compartment 15 from a pump 25 via a reducing valve 28, feed line 27 and a two-way and " off " valve 34. The liquid may be withdrawn from the plate and cylinder by a suction pump 30 which is connected to the compartment 15 through a reducing valve 32, a feed line 31 and the valve 34. These suction means may be used to control the rate of liquid flow from the cylinder 1 on to the printing plate, appropriate actuation of the valve 34 cutting off the air supply from the pump 25 whilst connecting the compartment 15 to the pump 30. By manually holding the valve 26 in a closed position the air pressure in the reservoir may be rapidly built up when the apparatus is started. If the compartment 11 is filled with a cleaning liquid the printing plate and the cylinder 1 and its wall and covering may be cleaned, the pump 25 being used to apply the liquid throughout the apparatus to the plate whilst the pump 30 is used to withdraw the contaminated liquid. Alternatively, the compartment 15 may be emptied, the plate and cylinder being cleaned by placing a tray of water under the cylinder 37 and then applying subatmospheric pressure to the reservoir through the pump 30. The liquid flow rate to the cylinder 1 is controlled by the reducing valve 28 usually within the range 0-5 lb. per square inch. The peripheral wall of the cylinder may be of porous ceramic material, carborundum or a polyvinyl copolymer. In use, excess liquid and/or ink is removed from the cylinder 1 by a scavenger roller 38 and the liquid may be indirectly applied to the plates on the printing cylinder, one or more fabric-covered dampener rollers being placed between the latter and the cylinder 1.

Title: Improvements in or relating to colour couplers and to their production and use in colour photography
Inventor: GREENHALGH COLIN WILLIAM
IPC: C07D207/416
Filed: 1959-12-23
Abstract: The invention comprises compounds of the general formula: <FORM:0944838/C2/1> wherein A is a trivalent radical derived from 1,2-phenylene, 2,3-naphthylene or di- or trimethylene, B is a colour coupler residue, Y is -CO-, -CONH-, -COCH2- or -COCH2S- and R is a hydrocarbon group which may be substituted. The residue B is such that BNH2 will react with the oxidation products of N,N-diethyl-p-phenylenediamine, formed during the development of a silver salt image with that compound, to yield a quinoneimine or azamethine dyestuff. Such compounds are prepared by reacting with BNH2 a compound of formula Z-A(CO)2N-R wherein Z is -COX, -CH2COX, -NCO, -NHCOOC6H5 or -SCH2COX and X is halogen. In examples, R is a 4, 6, 8, 10, 12, 14, 16 or 18C alkyl group, or 4-dodecylphenyl, benzyl or cyclohexyl and B is 5-keto-1-phenylpyrazol-3-yl, 4 - (4 - methoxybenzoylacetamido) - 3 - methoxyphenyl, b -(1-hydroxy-2-naphthamido) ethyl, 4-cyanoacetylphenyl or 4-(3, 5-dimethoxycarbonylphenyl) carbamylacetylphenyl.  Starting materials. (1) Trimellitic anhydride reacted with octadecylamine to give 4-carboxy-N-octadecylphthalimide which gave the 4-chlorocarbonyl compound with thionyl chloride. Other N-alkyl-4-chlorocarbonyl-phthalimides were similarly obtained. (2) Octadecylamine reacted with 4-nitrophthalic anhydride to give 4-nitro-N-octadecylphthalimide which was reduced with Raney Ni to the 4-amino compound; reaction of the latter with phosgene gave 4-isocyanato-N-octadecylphthalimide. (3) Tricarballylic anhydride (from the acid and acetyl chloride) reacted with 4-dodecylaniline giving N(4-dodecylphenyl) succinimidoacetic acid from which the acid chloride was obtained using thionyl chloride; N-octadecylsuccinimidoacetic acid was similarly obtained.  (4) Carboxymethylmercaptosuccinic acid reacted with 4-dodecylaniline giving N(4-dodecylphenyl) succinimidomercaptoacetic acid which afforded the acid chloride with thionyl chloride.  The compounds are used as colour couplers (see Division G2) either directly or in dilute alkali, in which case the imide ring is opened. Specific alkaline hydrolysis products isolated-(Examples 26 and 27) are 41-methoxybenzoylacet-2-methoxy-5 (3- or 4-cyclohexylaminocarbonyl-4-or 3-carboxybenzoylamino) anilide and its analogue in which benzyl replaces cyclohexyl.

Abstract: 1402388 Balancing by machining HOFMANN GmbH Gebr [trading as HOFMANN KG Gebr] 19 Sept 1973 [4 Dec 1972] 43924/73 Heading B3B In a method of balancing a workpiece by drilling or milling the workpiece, the depth of cut is sensed by a transducer 12 and a voltage signal is fed to a circuit 13, which latter takes into account the taper at the tip of the drill 7. A voltage signal is also supplied by the transducer 12 through a relay contact 16 to a differential amplifier 18, the output 19 of which provides a voltage proportional to the drilling depth, this output being connected to the second terminal of amplifier 18 and also to a terminal of a differential amplifier 20. Voltage is applied to the other input terminal of amplifier 20 by transducer 12 via a resistor 21. Amplifier 20 subtracts the voltage at its second input from that at its first input so that whilst contact 16 is closed the voltage at terminal 25 is zero. If the drill point passes through the workpiece 1, the pressure on a sensing pin 6 causes the latter to be depressed and a switch 34 is opened. This causes relay 35 to be released and contact 16 is opened. The drill passing through the workpiece increases the voltage at transducer 12 and therefore at the output terminal 25 of amplifier 20, and this voltage is applied to a circuit 26, the output 27 of which is subtracted in a differential amplifier 28 from the voltage at terminal 15, so that the voltage which is proportional to the amount of material removed is produced at terminal 33 which is connected to a display.

Abstract: 1435724 Pulse thresholding GENERAL ELECTRIC CO 19 Sept 1973 [6 March 1973] 43935/73 Heading H3T [Also in Division H2] A thresholding circuit for providing an output signal at a predetermined phase angle with respect to an A.C. input voltage 10 comprises transistors 40, 44 having identical electrical characteristics, a first current I 1 , proportional to the average value of the positive half-cycle of the input voltage, being applied to the collector-emitter circuit of the transistor 40 and a second current I 2 , proportional to the instantaneous value of the input voltage, being applied to the collector-emitter circuit of the transistor 44 at the collector of which the output signal is provided. The current I 2  is derived from a full wave rectifier 24, 26 whilst the current I 1  is derived from a full wave rectifier 20, 22 and a filter network 28, 30, 32. Whilst the current I 2  is less than I 1  the transistor 44 is saturated and the output voltage on line 50 is zero. At the instant I 2  equals I 1  the transistor 44 is no longer saturated and its increased collector voltage causes a pulse generator 52 to generate an output. By adjusting a resistor 48 and/or a resistor 38 the instant in the half-cycle of the input voltage at which the output signal is generated may be varied. Since both currents I 1 , I 2  are derived from the same source, variations of the input voltage do not alter the instant of generation of the output signal. The transistors are formed on the same integrated circuit chip and the application of the circuit to the firing of thyristors is mentioned.
