Abstract: 1330321 Lithographic plates EASTMAN KODAK CO 13 Oct 1970 [13 Oct 1969] 48580/70 Heading B6C A lithographic master is prepared on material such as a grained aluminium plate by an electrophotographic method in which a developed image is transferred to thea luminium plate by process steps involving the application of ten successive electrical potentials the second being the reverse polarity of the first. The first electrical potential is for polarity opposite to that holding the image such that the image is repelled from the aluminium plate. This allows the plate and the surface supporting the image to be properly adjusted without any possibility of image transfer. The second potential of reversal polarity has the effect of transferring the image. The repelling potential may be between 50 and 250 volts whilst the transfer potential may be between 400 and 600 volts. The imaged plate may be rendered oleophobic in the non-image areas by treatment with an aqueous gum arabiephosphoric acid solution. The surface supporting the developed image may be transparent such that a flooding exposure is given through the surface prior to or during application of the transfer potential.

Abstract: 1354948 Pulse modulation circuits; semiconductor oscillators MOTOROLA Inc 21 Oct 1971 [9 Nov 1970] 48913/71 Headings H4L and H3T The frequency of an astable multivibrator Fig. 3 varies linearly with the current I which flows through a part of the circuit and which is made to vary linearly with a control voltage, whereby the frequency varies linearly with the control voltage, and the total amount through the multivibrator is constant. The multivibrator transistors 20, 21 are cross-coupled either directly (Fig. 6, not shown) or through emitter followers 22, 23, and their emitters are joined by the frequency determining capacitor 26. If T20 is on and T21 off, a current I flows to source 31 and a further current I flows to C26 and thence to source 33, so that 21 flows in T20 until the plate of C26 connected to T21 emitter falls low enough to turn on T21. Reciprocal coupling then turns off T20, and T21 carries 21. One transistor of an emitter-coupled pair 24, 25 is arranged to conduct when that one of T20, T21 conducts to which its base and collector are respectively connected; and the current source 32 for T24, T25 is made to vary inversely to the sources 31, 33 so that the current in the load resistor 27 or 28, being the sum of the currents in T20 and T24, or T21 and T25, is kept constant. The resulting constant voltage across whichever of R27, R28 is conducting renders the frequency of the output linearly proportional to the current I. The sources 31, 32, 33 are transistors (51, 53, 52, Fig. 5, not shown), having a common emitter resistor (R2), the source 32 having its transistor (53) emitter directly connected to the resistor (R2) and its base at a reference potential to define the total current IT in the resistor (R2); and the other transistors (51, 52) having further resistors (R1) between their emitters and the common resistor (R2), and receiving the frequency control voltage at their bases, whereby each supplies the current I.

Abstract: 1,246,185. Polyester fibres of improved dyeability. TORAY INDUSTRIES Inc. 15 Oct., 1969 [15 Oct., 1968 (2)], No. 50591/69. Heading B5B. [Also in Division C3]  A polyester fibre contains from 0À5 to 10% by weight (based on the weight of the fibre) of a melamine derivative or an isomelamine derivative. The melamine derivative has the general formula wherein X, Y and Z represent identical or different groups and each stands for a group or -N(CH 2 ) n , in which R 1  and R 2  represents identical or different groups, or atoms, each represents a hydrogen atom, an alkyl group, an aralkyl group or a cycloalkyl group and n stands for an integer of from 2 to 10. The isomelamine derivative has the general formula wherein X<SP>1</SP>, Y<SP>1</SP> and Z<SP>1</SP> represent identical or different groups and each represents an alkyl group, an aralkyl group or a cycloalkyl group. One or both of the symbols R 1  and R 2  may represent an alkyl group containing from one to twenty carbon atoms. One or more of the symbols X<SP>1</SP>, Y<SP>1</SP> and Z<SP>1</SP> may represent an alkyl group containing from one to twenty carbon atoms. The polyester may be polyethylene terephthalate (or a copolymer thereof), poly-1, 4-cyclohexanedimethylene terephthalate (or a copolymer thereof) or a condensate of paraoxyethoxybenzoic acid. The melamine derivative may be N,N<SP>1</SP>,N<SP>11</SP>-tribenzylmelamine. The isomelamine derivative may be N,N<SP>1</SP>,N<SP>11</SP>-tribenzylisomelamine. The polyester fibre may be made by melt spinning a mixture of the polyester and the melamine derivative or the isomelamine derivative and drawing the spun filaments to form a yarn. The mixture may be made by adding the additive to the polyester before or during its polymerization or to chips of the polyester in the spinning apparatus. The melamine or isomelaminecontaining polyester fibres may be made by melt spinning the polyester, drawing the filaments thereby formed to convert them into a yarn and subsequently treating the yarn with a solution or dispersion containing the melamine or isomelamine additive, thereby causing the additive to diffuse into the polyester filaments of the yarn. The drawn polyester yarn may be subjected to heating and shrinking after it has been drawn and before it is passed through the solution or dispersion of the additive and may thereafter be redrawn. Alternatively, a solution or dispersion of the additive may be caused to adhere to the yarn after the yarn has been drawn and shrunk, and the yarn may thereafter be conducted through warm water or a heated zone to cause the additive to diffuse into the yarn. The yarn is subsequently redrawn. The yarn may be heated and shrunk after the spinning and drawing steps by immersing it in a hot high-boiling point solvent that has a swelling effect on the yarn filaments but does not react chemically with them. The organic solvent used in the above process may be dioxan, tetrahydrofuran, dimethyl sulphoxide, dimethyl formamide, dimethyl acetamide, or N-methyl-2-pyrrolidone.
