IPC: G06K9/00
Filed: 1958-03-18
Abstract: 912,916. Automatic character reading. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 18, 1959 [March 18, 1958], No. 8600/58. Class 106 (1). Character recognition apparatus comprises a source of sync. pulses and a normally inoperative counter, the counter being caused to count the sync. pulses and produce sampling pulses in response to a signal corresponding to the beginning of the scan of a character being received. As described, character bearing records are moved past a single photo-multiplier sensing tube 9, Fig. 2, by a drum 1 which also produces synchronizing pulses. The characters are scanned column-by-column, Fig. 1 (a), the photo-multiplier tube producing a " 1 " (pulse) if the amount of black exceeds 50% or an " 0 " (not pulse) if the amount of black is less than 50%, and each character is so shaped that the first column scanned produces a " 1 ". This " 1 " pulse turns on a flip-flop 13, Fig. 2, allowing the sync. pulses, of which there are eight per column, to pass to a counter 16, which, every time it reaches " 4 " applies a shaft pulse to a register 17. Thus the bits from the photomultiplier tube are shifted into register 17, approximately as the centre of each column is being scanned, and when the first " 1 " from the character has been advanced to the last stage of register 17, flip.flop 13 is reset off and the counter 16 and register 17 are both cleared.

Title: Preparation of 17-formyl steroids
IPC: C07J3/00
Filed: 1954-03-30
Abstract: 3a  - Hydroxy - 17 - formyl - D 9(11),16-androstadiene and -D 9(11)-androstene are prepared by heating the dialdehyde of formula <FORM:0746988/IV(a)/1> in an organic solvent, preferably an aromatic hydrocarbon, with a carboxylic acid salt of an organic nitrogen base, e.g. piperidine acetate; and thereafter, if desired, selectively hydrogenating the 16 : 17 double bond of the androstadiene to produce the D 9(11)-androstene derivative.  The intermediate dialdehyde is prepared from 3-keto-16 : 17-dihydroxy-D 4,9(11)-D-homoandrostadiene acetonide by selective hydrogenation and then reduction of the resulting 3-keto-D 9(11) compound to 3 : 16 : 17-trihydroxy - D 9(11) - D - homoandrostene acetonide, which is then oxidized with periodic acid.  In an example: 3-keto-16 : 17-dihydroxy-D 4,9(11) - D - homoandrostadiene acetonide in methanol containing sodium hydroxide is hydrogenated using palladium black or palladium on strontium carbonate as catalyst, and the resulting 3-keto-16 : 17-dihydroxy-D 9(11)-D-homoandrostene acetonide reduced with lithium aluminium hydride in ether to 3a  : 16 : 17-trihydroxy - D 9(11) - D - homoandrostene acetonide.  Oxidation with periodic acid in aqueous dioxan gives the hydroxy-dialdehyde, I, which is then cyclized in benzene with a mixture of acetic acid, piperidine and anhydrous sodium sulphate, yielding 3a  - hydroxy - 17 - formyl - D 9(11),16-androstadiene, which is then hydrogenated in benzene using a palladium-strontium carbonate catalyst to give 3a -hydroxy-17-formyl - D 9(11) - androstene.  The conversion of 3a  - hydroxy - 17 - formyl - D 9(11) - androstene to 3 : 20-pregnane-dione and D 9(11)-pregnen-3 : 20-dione is also described.  Treatment of the androstene with ethereal methyl magnesium bromide yields D 9(11)-pregnen-3a  : 20-diol (mixture of C20 epimers) which is then oxidized with chromic acid to the corresponding dione, or hydrogenated using a platinum oxide catalyst to 3a  : 20-pregnane-diol and then oxidized to 3:20 - pregnane - dione. Specifications 712,550, 719,529 and 746,427 are referred to.

Title: A regulator for an electro-erosion electrode tool

Filed: 1966-03-03
Abstract: 1,140,044. Electro-erosion. B. G. GUTKIN and G. A. KURGANSKY. 3 March, 1966, No. 9391/66. Heading B3V. [Also in Division G3] An apparatus for feeding a reciprocating electro-erosive tool 5 to the surface of a machined component 6 comprises a shunt wound motor 1, the armature current of which is controlled by a semi-conductor amplifier 3 which derives its input from a memory device 4 and which varies the average armature current in dependence upon the minimum voltage across the spark gap between the tool and the component in any one reciprocation of the tool. The voltage at the spark gap is measured using a bridge 32 comprising a resistor 34 across which is developed a voltage dependent on the voltage at the spark gap, and a voltage divider 35 which produces a constant voltage with which the voltage across resistor 34 is compared. A reduction of voltage at the spark gap causes an increase in the signal voltage supplied to the memory device 4, and causes a capacitor 24 to be charged via a diode 23 to a signal voltage dependent on the minimum voltage at the spark gap during any reciprocation of the tool. The signal voltage is passed from the memory device 4 via resistors 25, 26 and is combined with the output of a pulse generator 7 and applied to the input of the amplifier 3 which is operated in the switching mode at the pulse frequency of 100 c.p.s. When the signal is zero or a small value, a transistor 11 is continuously closed. When the signal voltage increases the transistor 11 is opened for part or all of each pulse causing its emitter potential to become more negative, opening a bi-stable trigger circuit comprising transistors 12 and 13 which was previously closed by positive voltage supplied through a resistor 14. During the open part of each pulse current is supplied to the armature 2 of the motor 1, and during the closed part no current is supplied to the armature, causing the bias at the base of a transistor 9 to drop to zero so that it opens, short circuiting the armature and braking the motor. As the armature current is switched at the pulse frequency of 100 c.p.s. the motor runs at an average speed which is dependent upon the minimum voltage at the spark gap. In order to protect the amplifier input circuit, a voltage limiting stabilizer 27 is provided at the output of the memory device.
