Patent GB-591097-A (GB)
Title: Improvements in or relating to alarm systems
IPC: G08B17/06
Filed: 1941-12-09
Abstract: 591,097. Fire alarm systems. NEWTON, E. P. (Telefonaktiebolaget L. M. Ericsson). Dec. 9, 1941, No. 15892. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 27, 1942] [Class 40 (i)] [Also in Group XXXVI] In a system in which one or more protective circuits are connected to a central station over a telephone line D.C. which normally flows in the line is replaced, on the occurrence of a complete break, by A.C. (or vice versa) to enable the central station apparatus to distinguish between breaks in the protective circuit and breaks in the line. Relays R1, R2 and R3 normally receive current over the protective loop and R2 and R3 attract their armatures. If the line becomes shortcircuited, the line current is increased sufficiently to energize R3 which lights lamps KL, SFL. If one wire of the portion AS2 of the protective loop breaks, R2 falls back and lights ASL, LL. If the line wire CL breaks, or if both wires of the portion AS2, or the single wire of the portion AS1 of the protective circuit break R1, R2 both fall, SR is energized to start the A.C. generators and a new bridge is made involving relays R4, R5 and the A.C. source O1. If the line is intact, R5 respond to the alternating current and energizes R6 and alarm lamps AL, ATL are lit and bell AK is sounded. If, however, the line is broken, R5 is not energized and R7 pulls up and KCL, CLL as well as LL, SFL are lit. When the faults have been cleared, the apparatus is re-set by actuating key A. When a fault is cleared after a complete breakdown, R4 is operated to re-connect R1, R2, R3 and R1 operates and locks itself releasing R4, R5, SR. R6 or R7 however remains locked up. After a short-circuit is cleared, R3 is able to hold in spite of the reduced current. R2 is unable to re-operate over the resistances of the protective circuit and has to be energized over key A or contacts of relay R4. Earth faults cause operation of JR1 and illumination of JF1. If the fault is on the upper wire, R3 also is energized and lights KL. Clearing the fault puts out JF, but leaves KL alight. Since JR1 is common to all the lines, the cumulative effect of several leaks may produce a signal, although no single line is seriously earthy. To guard against this, key BO may be used to connect up a less sensitive relay JR2, which only pulls up to a direct earth. To guard against the possibility that the protective circuit may be broken and remade again in very rapid succession, the resistance r2 may be replaced by a cut-out, which breaks the circuit permanently on the shortest possible interruption. In alternative arrangements, the normal supervisory current is alternating, direct current being used to distinguish between line faults and breaks in the protective circuit.

Filed: 1962-04-27
Abstract: To obtain resinous products which may be used without a binder to form the photoconductive layers of electro-photographic materials various organic photo-conductors are reacted with isocyanate and/or epoxy components.  In one embodiment (Example 5) the bisglycidyl ether of ethylene glycol is reacted with 4-[N-ethyl-N-(b -hydroxy ethyl) amino]-benzophenone at 170 DEG  C. under nitrogen and the unreacted ether removed under vacuum.  The residue is dissolved in cyclohexanone and reacted for a short time at 100% with a modified tri-isocyanate.  In another embodiment (Example 8) 3 - amino - a  - (41 - dimethylaminocinnamal) -acetophenone is added to an ethyl amyl ketone solution of a partly condensed epoxy resin obtained from diphenol propane and epichlorhydrin, and is reacted under reflux at 100 DEG  C.  To form a photoconductive layer the reaction mixture is diluted with methyl isobutyl ketone and methyl ethyl ketone and a small quantity of a modified tri-isocyanate added with sensitizing dyes-the mixture is coated on to a support and the solvents allowed to evaporate.  In a further embodiment (Example 4) a cyclohexanone solution of 2-hydroxy-4-diethylamino - 21 - carboxy - benzophenone (containing a small amount of Rhodamine B) is mixed with a concentrated solution in ethyl acetate of a modified triisocyanate obtained by reacting 1 mol of tri-methylol propane and 3 mol of toluylene-2: 4 and/or 2: 6-diisocyanate.  Condensation is effected at 151 DEG  C. and the product thrown out of solution by the addition of acetone.  In a further embodiment (Example 7) 2 - hydroxy - 4 - dimethylamino - a  - [4 - (methylb -hydroxyethy - amino) - cinnamal] - acetophenone and a concentrated ethyl acetate solution of a modified triisocyanate are dissolved in cyclohexanone and reacted at 150 DEG  C. The reaction mixture is diluted with methyl ethyl ketone and ethyl amyl ketone to form the coating composition.  In another embodiment (Example 9) an isocyanate component is made by the reaction at 148 DEG  C. of 2-ethyl-2-butylpropan-1 : 3-diol with toluylene-2: 4-(or 2: 6)-diisocyanate. The purified product is dissolved in cyclohexanone with 4-dimethylamino-phenyl-31-hydroxy-naphthyl-(21)-ketone and condensed at 135 DEG  C. to obtain a solution of the photo-conductive product. In another embodiment (Example 17) a concentrated ethyl acetate solution of a modified tri-isocyanate is dissolved in cyclohexanone with 2: 4-di-hydroxybenzophenone, and initially reacted under reflux at 150 DEG  C.  The temperature is then mixed to 200 DEG  C.-the cyclohexanone distills off.  The resin left is dissolved in mixed solvents to obtain the coating composition.ALSO:<FORM:1008633/C2/1> <FORM:1008633/C2/2> <FORM:1008633/C2/3> In Examples (6), (12) and (16), the trisiso-cyanate obtained from trimethylolpropane (1 mol.) and tolylene diisocyanate (3 mols.) is reacted with the compounds of the formulae given in Figs. 8, 23 and 21 respectively.

Title: Improvements in turbines, particularly internal combustion turbines
IPC: F02C5/06
Filed: 1944-08-30
Abstract: 586,056. Rotary engines. LINCOLN, J. H. Aug. 30, 1944,. No. 16458. [Class 110 (ii)] [Also in Group XXVIII] In a rotary internal combustion engine comprising rotors 11a, 11b secured to a shaft 25 and rotating in close face proximity to a stator 10, spring-urged vanes 14 carried by the rotors co-operate with tapered recesses 13 in the stator. Each vane springs first into the deep end of a recess and is gradually pressed back by the inclined base of the recess. Gas derived from combustion chambers 16 is led through passages 17 and slide valves 18 to impinge upon the forward faces 19<1> of rotor recesses 19, subsequently entering the deep ends of the stator recesses 13 as. rotation proceeds. A spring-pressed gasket 20 preferably surrounds each recess 19. Exhaust takes place through ports 60 and passages 61, 62. Each slide valve 18 is operated by a cam 21 which is stepped round by means of a star wheel 22 which is operated by pins 23 on the adjacent rotor. Combustion air is supplied by com-- pressors 24 in which pistons 26 are operated by rollers 33 carried by shafts 31 and co-operating with cam tracks 34 carried by the rotors. Air is drawn in through ball valves 28 (and through slots 32 as each piston approaches the bottom of its stroke) and is then compressed into the combustion chambers 16. Fuel is injected into the combustion chambers by pumps 36 operated by a cam 37 carried by one of the rotors, and is ignited by the temperature of the compressed air. A non-return valve 30 isolates each combustion chamber from its compressor during combustion. Variation of the quantity of fuel injected can be effected by moving a lever 40 axially by means of a hand control 43, thereby altering the stroke of the fuel pump plunger 39.' The fuel atomizer 29 is provided with an inner cylinder 47 having holes 48 which register with jet holes 45 provided in the main body 46 when the requisite oil pressure is reached. This registration is effected by the rotation of the cylinder 47 by an arcuate piston which is attached to it and which is urged round by the oil pressure against the action of a spring. Oil leakage is collected in an annulus 49 and drained off at 51. To relieve the pressure in the atomizer or to stop the engine, a cap 59 is screwed down to force a ball 67 off its seat, thereby putting the interior of the cylinder 47 into communication with the annulus 49 by way of relief holes 63. The compressor may be of the centrifugal type. Spark ignition may be employed.
