Divided out of 428,793. [Class 106 (i)] A record-card-controlled multiplying-machine comprises a card-reading means, selecting means operable under the control of a class indication on the record card to select, from a plurality of available factors on the card, one factor in accordance with the class indication, and multiplying-mechanism operable to multiply the selected factor by another factor. The invention is described as applied to a machine of the type disclosed in Specification 405,031; the card has a multiplicand section, two multiplier sections, and a classification section. The presence or absence of a hole in the classification section determines which of the multiplier sections will be selected for entry into the multiplier register. The card is fed from a supply stack 105, Fig. 1, between feed rollers 82 and over a conducting plate 107 to a contact roller 87. In the first card feed cycle the leading edge of the card reaches the reading brushes 109 and a brush 106 rests on the classification hole position. If a hole is present a circuit is completed through the plate 107 and a relay T, Fig. 2, is energized to throw contacts 418 to the position opposite to that shown in the Figure. The sockets 419 of chis set of contacts are connected to sockets 423 associated with the counter magnets 390 MP of the conventional totalizing register while the sockets 420, 421 are connected to sockets 424 associated with the brushes reading the two multiplier sections of the card. The sockets 422 of the multiplicand register 390 MC are connected to the sockets 424 reading the multiplicand section. During the second card feed cycle the selected multiplier and the multiplicand are read and entered in the respective registers and the card is fed by rollers 95 on to a tray 118 in the card punching section. The card feeding operation is suspended while the machine automatically performs the multiplying operation and punches the product on the card in the known manner. The machine can be adjusted to select the multiplicand instead of the multiplier by rearranging the plug connections. Factor selecting can be dispensed with by opening a switch 417. Specification 422,421 also is referred to.

Abstract: 355,501. Treating dough. UHL, J., (trading as UHL'S SÍHNE, J.), 17, Schagunag, Sibiu, Hermannstadt, Roumania. Aug. 14, 1930, No. 24350. Convention date, Aug. 14, 1929. [Class 28 (i).] Pieces of dougb, e.g. macaroni, are hung on pegs 25 on a rake 24 and are trailed by the rake over a board 4 and deposited thereon in parallel rows, the board then being traversed to carry the projecting end of the doughpieces past rotary cutters M which cut the pieces to uniform length. The board then carries the dough to a drying apparatus. The rakes drop into hooks 21 having stub spindles which seat in recesses 18 on a pair of discs 17 and remain stationary during the loading operation. Chains 11 carry a cross-bar 12 which, on movement of the chains, acts on arms 19a to turn the discs, thereby carrying the rake to a position where the hooks are caught by a second cross-bar 13 on the chain. The rake then trails the dough pieces till the hooks are tilted by a fixed stop A thereby releasing the dough-pieces from the rake. When the hook reaches arms 15 it is caught by a crossbar 15a carried by the arms, the arms 15 being rotated by the bar 13 coacting with springs 15b. The hooks are thus deposited in the recesses 18 and are released from the bar by cams operating on lugs N on the hooks.

Title: Carbon black
Inventor: BALKA WILLIAM HERMAN
IPC: C09C1/50
Filed: 1961-07-07
Abstract: <PICT:0977622/C1/1> <PICT:0977622/C1/2> <PICT:0977622/C1/3> Carbon black is produced by introducing hydrocarbons and air into the lower end of a furnace having an upper end provided with a restricted opening, partially combusting the hydrocarbons in a combustion zone in said furnace so that the resultant gases pass upwards from said combustion zone through a cracking zone, to and through a hood in said furnace and adjusting the height of the hood so as to vary the volume of the cracking zone according to the desired carbon black particle size, withdrawing the combustion gases through the restricted opening and separating the carbon black from the gases. The temperature of the combustion zone may be 1800-2400 DEG  F., of the cracking zone 2200 DEG -2600 DEG  F. and in the hood 2600-3000 DEG  F.  The furnace 10 (see Fig. 2) has a burner 100 having a semi-cylindrical upper section 101 provided with a plurality of spaced parts 125, a semi-cylindrical lower section 102 and conduits extending into the burner through the lower section for introducing gases. The upper section 101 which has a greater radius of curvature than the lower has spaced parts 125 distributed over the whole surface except along the longitudinal side edge portions extending upwardly 5 degrees from the edges.  Each of the parts has a straight bore portion 126 (see Fig. 5), whose diameter is preferably 8/10 th the thickness of the plates forming the upper section and whose length is 2/10 th the thickness. The upper flared portion 127 of each bore preferably has a radius of curvature which is 6/10 th the thickness of the plate. The hood is adjusted by winches 91 which are driven by an electric motor 90.  A scraper blade 130 is mounted in the burner to remove any deposited carbon black. Liquid hydrocarbons, e.g. oil may be introduced through spray heads 175 supplied by inlets 176.  In use the furnace is first preheated to 1800-2400 DEG  F. by natural gas.  Usually the ratio of air to gas is between 4 to 1 and 8 to 1. As the hood is raised, the size of the particles of carbon black increases. The mixture of carbon black and gases from the furnace 10 (see Fig. 1) is cooled in primary cooler 13 and then moved by fans 14 and 15 to cyclones 16 and secondary cooler 18.  The carbon is separated and collected in bins 20 and 24 and the gases exhausted to the atmosphere. The carbon may be pulverized and pelletized and then conveyed to a sizing shaker screen 30, rejected pellets being moved by the blower 32 back to pelletizer 28.

Title: Production of water-insoluble, highly basic anion exchange resins from epihalohydrins and alkylenepolyamines
IPC: B01J41/12
Filed: 1957-08-02
Abstract: Anion exchange resins are prepared by reacting 1 mol of an epihalohydrin with at least 1 mol of an alkylenepolyamine having at least one tertiary amino group and at least one primary amino group and/or at least one secondary amino group, until a gel is obtained which is dried and granulated.  If desired part of the alkylenepolyamine may be replaced by a polyalkylenepolyamine having only primary and secondary amine groups.  Preferably the product is quaternized with alkylhalides, e.g. methyl chloride, dialkyl sulphates, epihalohydrin or alkyl esters of aryl sulphonates, e.g. methyltoluene or -benzene sulphonate.  Amines containing tertiary amino groups specified are N, N-dimethylpropylenediamine; N, N-diethylpropylene diamine; N-morpholinopropylamine; dimethylaminoethylamine; diethylamino ethylamine; N, N-dimethyl-N1-methylpropylenediamine; N, N-dimethyl- N1- methylethylenediamine.  Polyalkylene polyamines having only primary and secondary amino groups may be employed or a polypropylpolyamine, e.g. iminobispropylamine.  The condensation may be performed in the presence of solvents, e.g. water, methanol or ethanol.  A surface active agent tending to prevent the fusion of the globules of condensate is preferably added.  Water formed during the reaction is removed azeotropically.  In Examples (1) a mixture of water and dimethylaminopropylamine is cooled to 30 DEG C. and epichlorhydrin added dropwise in molar ratio of 1,5 : 1 to the amine.  The condensate was poured into a flask containing orthodichlorobenzene containing 1% chlorinated rubber.  The mixture was heated to 105 DEG C. and an azeotropic mixture of water and dichlorbenzene distilled off until a well-defined resin bead was obtained which was filtered off and separated from residual dichlorobenzene by distillation and suspended in water containing lime.  The bead on regeneration had a basicity value of 18,5 Kgr per cubic ft.; (2) the beads were quaternized by treatment with gaseous methyl chloride and regenerated with HCl.  In Example (4) a mixture of dimethylaminopropylamine and iminobispropylamine was used; (6) epibromhydrin was used instead of epichlorhydrin; (7) the reactans were epichlorhydrin, iminobispropylamine and N-dimethylaminopropyl-N1-diethylethylenediamine.  U.S.A. Specifications 2,469,683, 2,469,692 and 2,543,666 are referred to.

Abstract: 1,153,285. Shift registers. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 3 June, 1966 [5 June, 1965], No. 24762/66. Heading G4C. [Also in Division H3] A shift register comprises a number of thyristor bi-stable circuits as in Fig. 1, with a common control circuit as in Fig. 2, the whole interconnected as in Fig. 3 (not shown). Positive timing pulses at 26 are differential at 24, 25 to cutoff transistor 23 so that terminal 2 temporarily assumes the potential of -E, which is more negative than the cathode of thyristor 1 which is returned to ground. The change in collector voltage of 23 is delayed by an integrating circuit 30, 31, and when capacitor 31 has discharged sufficiently to allow Zener diode 29 to conduct, transistor 28 is also cut-off, allowing terminal 9<SP>1</SP> to assume the potential of +E. If a positive data pulse is present at 8<SP>1</SP>, the AND gate comprising diodes 8, 9 allows the potential of +E to reach the gate of the thyristor through resistors 10 and 6. The thyristor then conducts and an output is obtained at 5. In the absence of a data pulse the + E potential is shorted by diode 8 and the thyristor is held off by the -E potential applied to its gate through resistor 7. Transistor 23 conducts again when the differential signal at its base has decayed, and after a delay transistor 28 also conducts and drops the potential at 9<SP>1</SP> to -E through resistor 32. The thyristor anode potential is restored by conduction of transistor 23, awaiting a further coincidence of positive signals at 81 and 91. Diode 11 facilitates the blocking of the thyristor. The thyristor output can be taken from its cathode and/or its anode.

Abstract: 243,683. British Thomson-Houston Co.. Ltd., (Assignees of Carter, E. F.). Nov. 25, 1924, [Convention date.]. Thermionic amplifiers, generators, and modulating systems; combined transmitting and receiving arrangements; coupling aerial and detector circuits; wired wireless systems.-In a combined transmitting and receiving set the oscillations of the transmitter are inhibited, when not required, by a high impedance inserted in the high tension supply to the oscillator, this impedance comprising a valve with negative grid. In the oscillator 2 the filament is connected through a resistance a to the grid and plate, the plate being in series with a rejector circuit b one point c of which is connected to the filament. High tension is supplied to the plate over a circuit comprising the filament, the choke d (which prevents the control valve from modulating the output of the oscillator 2), the plate-filament path of the control valve 7, the high-tension commutator @ of the generator 8, and the choke f. Normally this high-tension supply circuit is interrupted owing to the negative grid bias of the valve 7, which is provided by the battery 9 : but when voice currents from the microphone 6, amplified by the valve 5, act on the grid G7 through the transformer secondary 10, the impedance of the valve 7 is lowered and the valve 2 is consequently enabled to oscillate. The plate of the latter valve is connected through the condenser 12 and resistance g to the grid of the power amplifier 3 whose plate is choke coupled to the modulator 4. The output coil 13 is coupled to the tuned link circuit 14 and so through condensers 15 to the power line or other antenna 1. The receiver 16, tuned to the same frequency as the transmitter, is connected to the link circuit 14 by a further link circuit 18, but the latter is bridged by a diode 20 whose plate is somewhat negative with respect to its filament. This diode shunts the strong transmitter signals. but has no effect on the weak received signals.
