Title: Ketene-isocyanate addition compounds and process for their manufacture
IPC: C08G73/00
Filed: 1959-11-09
Abstract: Polymers of sulphomalonimides having the general formula <FORM:0939844/IV(a)/1> the polymers containing the recurring unit <FORM:0939844/IV(a)/2> in which R represents chlorine, fluorine, or a substituted or unsubstituted aliphatic or aromatic radical and R1 and R2 which may be the same or different and each represent hydrogen or an alkyl or aryl radical are obtained, admixed with the monomer, by reacting a ketene <FORM:0939844/IV(a)/3> with a sulphocyanate R-SO2-N=C=O in an inert solvent and at a temperature at which the products are stable and the reaction medium remains liquid.  The polymeric material is recovered by crystallizing out the monomeric product and then removing the solvent.  Reaction is generally effected at -70 DEG  to about 25 DEG C. In examples, ketene is reacted with a sulphocyanate in which R is (1) p-toluyl, (2) p-chlorphenyl, (3) chlorine, (4) fluorine or (5) naphthyl, polymeric material being isolated in Examples 1, 2 and 5.  Numerous other reactants are specified including methyl, diethyl, phenyl and methyl phenyl ketenes and methane-, nitro toluene- and chloro methyl naphthalenesulphoisocyanates.  The polymers may be used to treat textiles.ALSO:The invention comprises sulpho-malonimides of the general formula <FORM:0939844/IV(a)/1> in which R represents chlorine, fluorine or a substituted or unsubstituted aliphatic or aromatic radical and R1 and R2 are similar or dissimilar and each represents hydrogen or an alkyl N aryl radical and a process for their manufacture comprising reacting a ketene of the general formula <FORM:0939844/IV(a)/2> with a sulpho-cyanate of the general formula R-SO2-N=C=O in an inert solvent and at a temperature at which the reaction products are stable and the reaction medium remains liquid. Those imides wherein R is fluorine or chlorine decompose at room temperature.  Generally, reaction is effected at about -70 DEG C. to about 25 DEG C. depending on the stability of the products. Polymerised products are formed at the same time. Suitable solvents include chlorinated C1-2 aliphatic hydrocarbons, esters and ethers. Examples describe the preparation of malonimides as above defined wherein R1 and R2 are hydrogen and R is (1) p-toluyl, (2) p-chlorophenyl, (3) chlorine, (4) fluorine and (5) naphthyl, the compounds crystallising out while polymeric material remains in solution.  Numerous other starting materials are specified including methane-, nitro tolueneand chloromethyl naphthalene-sulpho isocyanates and methyl-, diethyl-, phenyl- and methyl phenyl-ketenes.

Abstract: 1,271,964. Coating apparatus. SINCAT SOC INDUSTRIATE CATANESE S.p.A. 30 July, 1969 [1 Aug., 1968], No. 38290/69. Heading B2L. [Also in Division C1]  A method of coating fertilizer granules with a resin comprises the steps of supporting the granules in a frusto-conical fluidised bed 4 supported by a gaseous current having a temperature of at least 20‹C and injecting a foam formed by mixing an aqueous or organic dispersion or solution of one or more resins into the bed, the shape of the bed causing the granules to rise in the axis of the bed and fall near the periphery of the bed the granules receiving coating as they rise and that coating being dried by the supporting air as they fall. The supporting air is blown by a fan 1 through a heater 2 into the bed. Coating medium 5 is introduced by a nozzle 6 and compressed air, to aid dispersion, through a concentric nozzle 8. A cyclone 11 separates accidentally removed granules from the outgoing air stream. Granules are fed in through a pipe 9 and out through an overflow 14 and the process may be continuous or discontinuous. Several examples of coating are described. In one example a ternary fertilizer was coated with a medium of a 50% by weight dispersion of polyvinyl' acetate. The dispersion was foamed in a mixer and fed in to the coating apparatus with an air stream at 70‹C. In a second example fertilizer granules were coated with 10% by weight of polyvinyl acetate from a 20% dispersion of the resin.

Title: An automatic steering system for dirigible craft
IPC: G05D1/02
Filed: 1959-11-18
Abstract: 922,883. Automatic steering control. LICENTIA PATENT - VERWALTUNGS G.m.b.H. Nov. 18, 1959 [Nov. 20, 1958], No. 39112/59. Class 38 (4). In a system for automatically controlling the course of a dirigible craft, a control surface is adjusted, by an electrical controller in dependence on a course deviation signal, and adjustable devices are provided to respectively select (a) the value which the course deviation signal must exceed to cause operation of the control surface, and (b) the point at which control is cut-off prior to the control surface reaching its final position. In Fig. 1, when a ship deviates from a course determined by the setting of a trimming potentiometer 11, adjustment of a potentiometer 1 by the repeater 3 of a gyro-compass (not shown), energizes windings 17, 18 of magnetic amplifiers 4, 5 respectively controlling the energization of D.C. relays 6, 7. If the course deviation exceeds, in either sense, a value determined by the setting of a potentiometer 27 energizing biasing windings 19, 20 of the magnetic amplifiers, the appropriate relay 6 or 7 is actuated so that steering gear (not shown) moves rudder 22 in the appropriate direction to restore the ship to the set course. Follow-up is provided by energizing further magnetic amplier control windings 15, 16 from a potentiometer 14 operated by the rudder. To oppose hunting, the rudder position corresponding to zero follow-up signal is adjusted by switches 25, 26, one or other of which is operated through a slipping clutch by the compass repeater 3 according to the sense in which the ship is turning. When correction is initiated by operation of relay 6 or 7, a switch 31 or 32 opens the circuit to potentiometer 27 whereupon a potentiometer 28 becomes effective to determine the energization of biasing windings 19, 20 so that correction continues until course deviation is reduced to a value suited to the overrun of the steering gear. Sensitivity of the system is adjusted by ganged rheostats 12, 13. Modifications involving the use of alternating current control signals, selsyn or capacitative transmitters instead of potentiometers, and valve or transistor amplifiers instead of magnetic amplifiers are referred to.

Title: Transistor biasting arrangement

Filed: 1974-09-10
Abstract: 1477393 Transistor bias circuits RCA CORPORATION 10 Sept 1974 [21 Sept 1973] 39371/74 Heading H3T A bias supply for a load comprises; a first transistor 13 with its emitter connected to a reference source; a second transistor 12 through which flows a predetermined portion of the base current of transistor 13; and a current amplifier 15 or 30 having an input connected in the path of transistor 12 through which flows the predetermined portion of base current of transistor 13 and an output producing the required bias current. In one embodiment, Fig. 4, a long tailed pair 141, 142 has its "tail" current Ic provided by a circuit which includes transistors 12, 13 interconnected as shown so that the current Ic corresponds to a current Ic/hfe flowing in the collector circuit of transistor 12. This current is applied as the input to a current amplifier 301 ... 304 whose gain is -¢ so that currents of Ic/2hfe appear at the outputs (collector circuits of 303, 304). These currents are applied to the bases of the long tailed pair transistors 141, 142 to provide the required emitter currents. As shown, the gain of + is achieved by the use of the two transistors 301, 302 connected in parallel. In a first alternative, Fig. 5 (not shown), two transistors (12a, 12b) with their base-emitter circuits in parallel are used in place of the single transistor 12. The collector current of one of these is thus Ic/2hfe and is applied a unity gain current amplifier (401, 303, 304). In a second modification, Fig. 6 (not shown), the transistor 13 is also replaced by a pair of transistors (13a, 13b). In a third modification, Fig. 7 (not shown), the base bias for transistor 12 is obtained by coupling its base to the collector of transistor 13. In an alternative embodiment, Fig. 3, the bias circuit is associated with an amplifier 21 to which is connected an input source 25, and which feeds an output to load 24. In this circuit, the collector current of transistor 12, Ic/hfe, is fed to the input of a first current amplifier 15 having a gain m and the collector current, Ic, of the transistor 13 is fed to the input of a second current amplifier 20 also having a gain m. The outputs from the two current amplifiers are applied to the base and collector respectively of the transistor amplifier 21 to provide base and collector currents mIc/hfe and mic respectively.
