Abstract: 695,197. Photomechanical printing surfaces. KODAK, Ltd. Nov. 3,1949 [Nov. 3,1948], No. 28185/49. Class 98 (ii). Printing-plates having a relief image are made by coating a support with a layer of a polymeric soluble cinnamic acid (including a ring substituted derivative thereof) or furylacrylic acid ester of a polyvinyl alcohol or cellulose, exposing to a light image to insolubilize the ester in the exposed areas thereof and washing away the unexposed areas with a solvent for the ester. Polyvinyl cinnamate is the preferred ester and instructions for making this from cinnamoyl chloride and polyvinyl alcohol are provided; similar esters made from o-chloro- or m-nitro-cinnamic acid chlorides or furacrylyl chloride, or the corresponding cellulose esters, may be used. The esters are applied to plates as by whirling or machine coating methods, polyvinyl cinnamate in a mixture of xylene, toluene, n-butyl alcohol and isopropyl alcohol, polyvinyl m-nitro-cinnamate in nitrobenzene and cellulose cinnamate in 1 : 4. dioxane, the coatings being dried at room or elevated temperature in subdued light. The coated plates, which have a speed of the order of bichromated gelatine, are exposed as under a line or half-tone image and developed by washing with a hydrocarbon such as benzene or with one of the above-mentioned solvents. Particular types of plates provided with an insolubilized polyvinyl cinnamate relief image in this way are described in examples: (1) A zinc plate is etched through the relief image and the latter rubbed off as with the aid of benzene or acetone to form a relief plate. (2) A copper plate is chromium-plated under the usual conditions to produce a lithographic plate. Baking and swabbing the plate can be dispensed with. (3) A degreased copper plate is etched through the relief image with ferric chloride, burning in and scrubbing during etching unnecessary. (4) The support is cellulose ester, parts not protected by the relief image are de-esterified as with sodium methylate to repel greasy ink in these parts. (5) The relief image is produced on grained zinc or aluminium plates, which may then be used directly on a lithographic press. (6) Zineated or anodized aluminium plates are provided with the relief image or the latter may be formed on a glass plate and etching carried out with hydrofluoric acid. Example 7 describes the use of cellulose cinnamate for forming a lithographic plate. Specification 695,262, [Group IV (a)], is referred to.

Patent GB-861689-A (GB)
Title: Improvements in and relating to spark ignition systems for internal combustion engines
Filed: 1959-08-25
Abstract: 861,689. Ignition systems. GENERAL MOTORS CORPORATION. Aug. 25, 1959 [Sept. 12, 1958], No. 29024/59. Class 7(4). [Also in Group XXXV] in an ignition system a condenser and the primary winding of an ignition transformer are connected in series across a charging circuit to which a relaxation oscillator circuit is connected so as to control the charging and discharging of the condenser, the charging circuit being supplied by a power supply circuit including a transistor oscillator. As shown the transistor oscillator 24 comprises a pair of transistors 42, 44 which become conductive alternately. The oscillator operates as a self-excited generator of alternating current which may have a frequency in the neighbourhood of 20,000 cycles per second. Assuming that the engine is running the voltage appearing between the centre tap 33 of the secondary winding and the lead 97 as applied to a voltage doubler circuit that includes diodes 30 and 32 and condensers 90 and 92. The p-n junction diodes 30, 32 rectify the AC voltage. The DC voltage appearing between junctions 91 and 94 is used to fire the spark plug 10. When the breaker points 100 are closed the condenser 120 is charged through the silicon diode 112 and inductance 114. At the same time the condenser 140 is charged through the resistor 141. When the voltage on the capacitor 140 is great enough the thyratron tube 124 is ionized. Ionization of the tube causes the main condenser 120 to discharge through the primary winding 22 of the high frequency ignition transformer 20. When all of the energy of condenser 140 has been used up the ionization potential on the grid of the tube 124 disappears and the thyratron tube becomes non- conducting. At this time the condenser 140 proceeds to become charged again from the power source of the voltage divider 85 through its charging resistor 141. In this way the resistor 141, the condenser 140 and the grid cathode elements of the thyratron tube 124 constitute a relaxation oscillator circuit. Thus timed pulses of grid excitation continues as long as the breaker contacts 100 are closed. The tube 126 drains off the residual charge that is accumulated by the condenser 120. When it is desired to start the engine the switches 60 and 70 are closed. Contacts 64, 65 and 66 are short circuited together and a circuit is completed for the starting motor 72. In addition the armatures 76 and 77 will be moved to engage the contacts 81 and 83 respectively. The voltage that is lost during the cranking by the starter motor is thus compensated for. A conventional distributer (not shown) may be employed. Specification 861,690 is referred to.
