Title: Manufacture of 1-alkylamino-4-arylaminoanthraquinones
IPC: D01H1/00
Filed: 1933-12-11
Abstract: 1 - Alkylamino - 4 - arylaminoanthraquinones are prepared by reacting in a single operation a 1 . 4 - dioxyanthraquinone in presence of its leuco derivative or in the form of its leuco-derivative or in the presence of a reducing agent, with or without a condensing agent, with an aliphatic and an aromatic amine, such as p-phenylenediamine or p-aminophenol.  Specified alkylamines are methylamine, ethylamine, oxyethylamine, oxypropylamine, and other specified aromatic amines are aniline and p-toluidine.  In some cases to obtain dyes suitable for dyeing acetate artificial silk it is advantageous to use a mixture of two or more aromatic amines or two or more alkylamines. In examples: (1) a mixture of leuco quinizarin and quinizarin is condensed in ethanol with b -oxyethylamine and p-phenylenediamine (acetate artificial silk green shades); a mixture of b -oxyethylamine, methylamine and p-phenylenediamine may be used or the b -oxyethylamine may be wholly replaced by methylamine in the foregoing operation to give green dyes for acetate artificial silk; leuco quinizarin alone may also be reacted with b -oxyethylamine and p-phenylenediamine in ethanol and the product oxidized; (2) a mixture of quinizarin and leuco quinizarin is condensed with b -oxyethylamine in ethanol after which p-aminophenol, hydrosulphite and boric acid are added and condensation continued; the product dyes acetate artificial silk green-blue shades.  The Specification as open to inspection under Sect. 91 comprises also the following examples: (3) leuco quinizarin is condensed with p-phenylenediamine and methylamine in presence of sodium chlorate and boric acid in ethanol; p-phenylenediamine may be replaced by p-aminophenol or p-toluenediamine and methylamine by ethylamine or propylamine; (4) leuco quinizarin is condensed in methanol with p-phenylenediamine, b -oxyethylamine, sodium chlorate and boric acid are added and condensation continued. This subject-matter does not appear in the Specification as accepted.

Patent GB-355204-A (GB)
Abstract: 355,204. Ticket punching and printing apparatus. ALLGEMEINE ELEKTRICITATS-GES., 2, Friedrich Karl-Ufer, Berlin. Feb. 15, 1930, No. 5165. Convention date, Feb. 15, 1929. Void [Published under Sect. 91 of the Acts], [Class 106 (iii).] Ticket punching and printing apparatus comprises means which ensure that printing mechanism is only released for printing after punching and registering have taken place. The term punching covers such operations as making a marking, a perforation, a point, a differently coloured or im, pressed mark or a mark produced by passage of an electric current. Keys 6 actuate through levers 7 punches 8 and simultaneously operate through pawls 9, counters 10. The punches are divided into groups each connected by a locking pawl 11 with the printing roller 4. The tooth 12 of a punch 8, spring-returned after perforating the ticket strip, engages the pawl 15 and lifts the pawl 11 clear of the printing roller 4 which can then be rotated by means of a hand crank. Near the completion of a revolution of the printing roller a pin 20 on it engages the arm 18 pivoted at 19 and moves the pawl 11 to the left simultaneously moving the pawl 15 out of engagement with the tooth 12 so that when the pin 20 has passed the arm 18 the pawl 11 is moved to the right by the spring 17 and can re-engage with the printing roller. The ticket strip 1 is fed over the guide roller 2, under the punches 8 and between the printing roller 4 and the counter-pressure roller 5, and is torn off at the blade 14, and it will be seen that each ticket is half printed at the issue of the previous ticket, the punching taking place on the unprinted portion and before that portion is printed.

Title: Improvements in or relating to multipliers
IPC: G06F7/52
Filed: 1961-10-04
Abstract: 945,527. Binary multipliers. STANDARD TELEPHONES & CABLES Ltd. Oct. 4,1961 [Dec. 29, 1960], No. 35735/61. Heading G4A. In an electrical binary multiplication circuit, successive pairs of the multiplier digits control entries of the multiplicand, the pair of digits "11" (i.e. decimal 3) causing addition of four times the multiplicand and subtraction of once time the multiplicand. The mathematical theory of the multiplication method employed is discussed in detail in the Specification. The circuit described employs a multiplier/product register 102, a multiplicand register 101 and a partial product register 103. The registers 101-103 comprise bi-stable flip-flop circuits. Commencing with the lowest pair, successive pairs of multiplier digits are supplied from flip-flops a,b of the register 102 to a logical circuit 104, a circuit including a delay 106 being arranged to increase by one unit the value of the pair if the previous pair was "11". Outputs 12-0 to 12-3 of the circuit 104 are applied to a transfer block 105 to control an appropriate transfer from the multiplicand register 101 to the partial product register 103. The multiplicand 101 is supplied in direct or complement form from a transfer circuit 111 unchanged or via circuit 112 or doubled via a circuit 113 to a mixer circuit 114 coupled to the partial product register 103. According as the multiplier digits are "01", "10", "11", the multiplicand is transferred directly via circuit 112, directly via circuit 113, and in complement form via circuit 112 together with a direct transfer via circuit 112 in the next step. Numbers stored in the partial product register 103 includes a sign digit #. Under certain circumstances, a round carry from the sign digit flip-flop via a line 17 and "and" gate 110 controlled by the lowest digits a, # in the register 103 is applied to the lowest order α. When a transfer step has been completed, the two lowest digits α, # in the register 103 are applied together with the sign digit # to a logical circuit 107, whose output supplies the related pair of digits f, g, in positive form for the product, to the register 102.

Title: Improvements in or relating to tube cleaning apparatus for boilers and the like
IPC: F28G3/16
Filed: 1933-12-20
Abstract: 429,365. Boiler cleaners. HANDOLL, P. G., 340, Brownhill Road, Catford, and DIAMOND BLOWER CO., Ltd., 91, Bishopsgate, both in London. Dec. 20, 1933, No. 35823. [Class 99 (ii)] A cleaner for marine fire-tube boilers of the kind in which a steam jet is directed onto the tubes to be cleaned from a rotatable nozzle 17, which is located within a tubular housing 16 mounted in the wall 11, 12, 13 of the boiler furnace and is slidable axially between the two extreme positions shown by full and dotted lines in Fig. 1, is provided with a snapover device to ensure rapid movement of the nozzle from its operative to its inoperative position. The nozzle is formed with an enlargement 19 adapted to coact with a seating 18 on the inside of the housing 16, and is mounted on the end of a spindle 29 which is provided at its outer end with a chain pulley 31 and intermediate its ends with a piston 34, of smaller diameter than the nozzle, and also a valve 35 having a plain cylindrical portion 36, of smaller diameter than the piston, and a conical seating 37. The piston 34 is located within a cylindrical extension 33 of the cover plate 30 of the wall casting 14 carrying the housing 16, and the valve seating 13 is adapted to coact with a ring 40 located on arms 38 projecting from the casting extension 33, cleaning steam being admitted from a supply passage 41 to the space between the casting 14 and the extension 33 and arms 38. The cleaner is completed by a lever 45 having a forked arm 46 engaging a groove 47 in the hub 48 of the pulley 31, and a spring 49 adapted normally to retain the nozzle in its inoperative or retracted position. In operation, and with the nozzle retracted, the lever 45 is drawn forward to shift the spindle 29 axially, thus advancing the nozzle into its operative position with the enlargement 19 engaging the seating 18 and opening the valve 35, the movement of the nozzle being assisted when the valve is opened by the differential steam pressure on the said nozzle. The nozzle is then rotated, and finally retracted by pushing back the lever 45. The retraction of the nozzle is at first resisted by the steam pressure, but immediately the cylindrical portion 36 of the valve enters the seating 40 the differential steam pressure on the piston 34 will effect rapid movement of the nozzle to its initial position. Condensate in the casting 14 is removed by a drain passage 50 which is connected to a blow-off pipe 51 and is provided with an ejector jet 52 communicating with the steam supply. The nozzle is preferably provided with a nozzle cap 21 having several orifices, e.g. three, inclined in various directions as described in Specification 429,366. Fig. 5 shows a modification for a locomotive boiler in which the casting 14 is mounted directly upon the front plate 73 of the firebox by studs 74 and the nozzle has a shorter stroke and is both moved axially and rotated by a single handle 71.
