Title: Polarised electromagnetic relays
IPC: H01H51/12
Filed: 1961-12-18
Abstract: 1,002,574. Electromagnetic relays. AMERICAN MACHINE & FOUNDRY CO. Dec. 18, 1961 [Dec. 28, 1960], No. 45355/61. Heading H2B. In a polarized electromagnetic relay having two windings on parallel magnetic cores with a parallel permanent magnet between them, an armature pivoted at one end of the permanent magnet is arranged to be normally biased to only one of the cores. As shown in Fig. 1, the cores 3, 4 and longitudinally polarized permanent magnet 9 are mounted on a magnetic return member 8 and the permanent magnet retains the armature 13 on its knife-edge 11. Fig. 1 shows the armature attracted to the core 3 and engaging a non-magnetic spacer 6 when the coil 1, 2 are energized to assist the permanent magnet flux in core 3 and oppose that in core 4. On de-energization the contact spring 24 moves the armature clockwise to a position where it engages the core 4 which does not project so far from the member 8 as does the core 3 with its spacer 6. The armature is retained in this position by the permanent magnet which then has its face 10 closer to the armature 13 than its face 10 is as shown. The core 4 may be of equal length to the core 3 with its spacer 6 (Fig. 5, not shown) and with this arrangement the knife edge is offset as shown in Fig. 7 to provide the magnetic bias. In Fig. 8 (not shown) the magnet top is flat and the armature pivots on a pin above the flat magnet end. Fig. 9 shows an armature 42 pivoted at 41 and biased by a magnet pole 45 which projects toward one of the cores 44. The non- magnetic spacer 43 is shown mounted on the other core end but in all the arrangements described the spacer can be mounted on the armature end instead of on the core 3.

Abstract: 1,153,569. Evaporators, multiple-effect type. GENERAL ELECTRIC CO. 12 Oct., 1966 [21 Dec, 1965], No. 45647/66. Heading B1B. Liquid to be distilled is pumped in parallel through heaters 19 disposed within three evaporator stages I, II, III, maintained at successively lower pressures, and the heated liquid is ejected onto, and flows in film-form down, vertical heat conductive surfaces 20, that of stage I being heated by steam source 21. Some of the liquid evaporates from each downflowing film, and the vapours condense on the opposite surface 23 of the stage or, in the case of the last stage, on coil 25 which is supplied with cooling water. Steam-condensate 22a is directed onto the outer surface of heater 19 in the right-hand compartment of stage I, where some of the condensate flashevaporates and subsequently condenses on heater 19, thereby heating feed-liquid flowing within. The films of liquid flowing down surfaces 20 in stages II and III are heated by the condensation on the surfaces 23 of vapours evolved from the liquid-films flowing down surfaces 20 in stages I and II, respectively. The liquid flowing from the surface of heater 19 in the right-hand compartment of stage I mixes with the condensate flowing down surface 23 in that stage; and the combined liquid 22b is directed over the heater 19 in the righthand compartment of stage II. The heater in the right-hand compartment of stage III is similarly heated by the flash evaporation and condensation of the liquid withdrawn from the right-hand compartment of stage II. Unevaporated liquid 24 withdrawn from the lefthand compartments of stages I and II is directed onto the outer surfaces of heaters 19 in the left-hand compartments of stages II and III, respectively. The condensate from the surface of coil 25, together with liquid flowing off heater 19 in the right-hand compartment of stage III, is withdrawn from the system by pump 26. Unevaporated liquid is withdrawn from the left-hand compartment of stage III by pump 27. There is also described a threestage multiple-effect evaporator of similar type in which the feed liquid flows in series through the heaters in stages III, II and I, and is then ejected onto the vertical evaporation surface of stage I. The unevaporated liquid collected at the foot of this surface being then ejected onto the vertical evaporation surface of stage II.

Title: Fuel blending system
IPC: C10L1/06
Filed: 1963-11-22
Abstract: In a system for blending at least two fuel substances, a signal, representing the difference between measured octane number of the blend and a desired octane number is utilised to control the addition of one of the substances and thereby reduce the difference to zero automatically.  As described, a blended petrol is produced by supplying several different constituents from separate tanks to a mixing tank from which the mixture is withdrawn and returned by a circulating pump to effect mixing. Signals corresponding to measurements of octane number of the mixture, the quantity of mixture, and the quantity of anti-knock agent supplied to the mixture are fed to an electrical computer which controls the addition of anti-knock agent intermittently until a mixture having a desired octane number is produced ready for shipment.  After each addition of anti-knock agent, which is computed so that it is slight less than the required to bring the blend to the desired octane number, the blend is mixed and the next addition delayed until the octane number has been substantially constant for a predetermined interval.  A signal is given if anti-knock agent concentration exceeds an allowable maximum.  The computer comprises potentiometers, memories and multivibrator circuits.

Abstract: 1,236,387. Electronic counters. E.M.I. Ltd. 17 Oct., 1968 [17 Oct., 1967], No. 47213/67. Heading G4A. [Also in Division H3] Each stage of a chain circuit comprises a pair of transistors of complementary type, both of which conduct or not according to whether the stage is set or not, a shift pulse causing a set stage to apply a setting pulse to the base of one of the transistors of the next stage, said base being connected to the other transistor of its pair through a uni-laterally conducting device which is rendered non-conducting by the setting pulse. A ring counter comprising such stages has a control circuit which ensures that at all times one and only one stage is set. Transistor 31 in the control circuit provides a constant voltage on conductor 16 feeding all the stages 1, 2, 3, . . while transistor 36 draws constant current from conductor 10. Positivegoing input pulses at 21 bottom transistor 28 to stop momentarily the flow of current in conductor 10. Assuming that stage 1 is set with transistors 6, 7 conducting then cessation of current in conductor 10 cuts off 6, 7 so as to apply a + ve going pulse to terminal 12. Resumption of current in conductor 10 leaves stage 1 at cut-off and stage 2 conducting. A diode 19 between the base of transistor 6 and the collector of transistor 7 becomes non- conducting during the setting pulse and enhances the effect of this pulse on transistor 6. Faulty operation.-If no stage or more than one stage is set then the potential on conductor 10 is more negative than normal and draws current through diode 39, so turning on transistor 38. The collector of 38 is connected directly to the collector of transistor 6 in stage 1 so that transistors 7, 6 turn on in succession. Modification.-The collector of 7 may be connected by resistor and diode in series to the output 12. The on stage charges the capacitor 11 of the next stage to a potential intremediate the off and on states. Read-out may be effected from terminals 40, 41, 42....

Abstract: The invention comprises compounds of the formula <FORM:0980104/C3/1> where a and n are each 1 or 0.  They are prepared by the reaction of tetraphenyldisiloxane diol-1,3 or hexaphenyltrisiloxane diol-1,5 with the appropriate diorgano dihalosilane, in the presence of a hydrogen halide acceptor, e.g. a tertiary amine, particularly pyridine. The reagents are dissolved in an inert solvent, e.g. THF, n-hexane, ether, and toluene.  The hydrohalide precipitate is removed, then the solvent, and the product is recrystallized. Polymers containing recurrent units:- <FORM:0980104/C3/2> where a and n are as above, are prepared from the compounds (I) by heating them alone at 250-350 DEG C., or, preferably, with a catalyst in the minimum of an inert solvent at 110-170 DEG  C. A suitable catalyst is a 0.01-1% dispersion of KOH in octamethylcyclotetrasiloxane, amounting to 10-100 p.p.m. of KOH in monomer.  The polymers have MW's of 10,000 to 5,000,000 and are soluble in benzene and toluene.  Copolymers may be made in a similar manner from the compounds (I) with themselves or other cyclic polysiloxanes, such as those of Specifications 980,101, 980,102, 980,103, 980,105, 980,106, 980,107, 980,108 and 980,109. The homopolymers with units (II) cannot be cured, but copolymers containing vinyl or adjacent methyl groups can be cross-linked by conventional free radical (e.g. peroxide) curing agents, or by irradiation with e.g. 50,000 to 20,000,000 eV electrons.
