Title: Improvements in the rotor and stator construction of gas turbine engines
IPC: F01D25/22
Filed: 1958-10-24
Abstract: 867,600. Turbine disc couplings. GENERAL ELECTRIC CO. Oct. 24, 1958 [Nov. 13, 1957], No. 34074/58. Class 80 (2). [Also in Groups XXVI and XXXIV] In a rotor and stator construction for a gas turbine engine, a rotor comprises a plurality of axially aligned and axially spaced wheels which are interconnected by a flexible torque transmitting means, and the rotor is supported by air bearings. In Fig. 1, wheel discs 14 are flexibly connected by transmitting members 21 and 22 which are fastened on opposite sides of each wheel disc. Circumferentially spaced spokes 23 on one of the members 21, 22 engage in axial slots provided in the other member. This construction permits each wheel to adjust itself relative to an adjacent wheel during operating conditions. Each rotor wheel is supported around its shroud 28 by air bearings 25 in the stator casing 18. These air bearings each comprise annular recesses 26 provided with pressurized air through line 27 from a source such as the compressor itself. Axial thrust is counteracted due to the extension of the shroud 28 into the recess 26 providing a side air bearing 29 which acts as a thrust bearing for each wheel. Fig. 3 illustrates a modification wherein air bearings are arranged at the inner ends of the stator vanes. An extension 31 near the periphery of each wheel disc 14 has a load-supporting peripheral surface 32 co-operating with an annular recess 33 at the inner ends of stator vanes 34 the recess being pressurized by air as before. When the gas turbine engine is started from rest an auxiliary air supply or self-lubricating bearings is provided.

Title: Improvements in or relating to the production of phenanthridine derivatives
Filed: 1946-11-21
Abstract: Phenanthridine derivatives believed to have the formula <FORM:0620732/IV (b)/1> where R1 is phenyl, R2 is alkyl or aralkyl and R3 is a primary n-butyl or n-amyl group are obtained by reacting with primary n-butyl or primary n-amyl alcohol the product obtained by treating a quaternary salt of 2 : 7-diamino-9-phenyl phenanthridine with an excess of aqueous alkali.  Preferably the butyl or amyl alcohol is added to the phenanthridinium salt before the addition of the aqueous alkali. The products are crystalline materials which are readily converted into phenanthridinium salts of increased purity with liberation of amyl or butyl alcohol, by warming with an appropriate acid or salt of an acid with a weak volatile base, e.g. an ammonium salt.  In examples: (1) 2 : 7-dinitro-9-phenyl-10-methyl phenanthridinium chloride is reduced to the diamino compound and treated with aqueous caustic soda and amyl alcohol to give an amyl oxide which on boiling with aqueous ammonium bromide gives 2 : 7-diamino-9-phenyl-10-methyl phenanthridinium bromide; (2) 2 : 7-dinitro-9-phenyl-10-methyl phenanthridinium methosulphate is reduced to the diamino compound and treated with n-butanol and aqueous caustic soda giving a butoxide which is boiled with aqueous hydrobromic acid to give the product of (1); (3) a solution of 2 : 7-dinitro-9-phenyl-10-methyl phenanthridinium salts is reduced to the diamino derivatives and treated with aqueous sodium hydroxide and butanol to give 2 : 7-diamino-9-butoxy-9-phenyl-10-methyl-9 : 10-dihydrophenanthridine which is treated with aqueous hydrobromic acid to give 2 : 7-diamino-9 - phenyl phenanthridine - 10 - methobromide monohydrate; and (4) the butoxide obtained in (3) is heated with aqueous hydrochloric acid to give 2 : 7-diamino-9-phenyl-10-methyl phenanthridinium chloride which is crystallised by the addition of a large volume of acetone.  Specification 611,745 is referred to.

Title: Improvements in apparatus embodying electric discharge lamps
IPC: H05B41/39
Filed: 1929-08-26
Abstract: 330,196. Gramophone Co., Ltd., and Browne, C. Aug. 26, 1929. Thermionic-valve circuits.-In apparatus in which the illumination of an electric glow- or arcdischarge lamp is varied according to electric variations, for example, in photographic soundrecording, a current-limiting device separate from the devices used to amplify the electric variations is included in the circuit and comes into operation only when the amplitude of the electric variation exceeds a predetermined value and then operates to prevent, or minimize the risk of, the voltage across the lamp falling below the cut-off voltage. Abnormally loud sounds are thus prevented from temporarily extinguishing the lamp. Current variations from a microphone and amplifier are applied to the lamp 5 through a transformer 14 in series with a thermionic diode 16 and a battery 17 of such voltage that, on the receipt of an abnormally loud sound, the diode commences to rectify, i.e. ceases to conduct at the negative peaks of the incoming voltage variations. Steady illumination is produced by a battery 7 in series with a stabilizing resistance 6 and a choke 18 preventing the incoming variations from passing through the battery 7. A resistance 15 assists in maintaining a linear relation between the current and voltage in the diode 16.

Title: Improvements in or relating to time division communication systems
IPC: H04J3/20
Filed: 1959-10-16
Abstract: 921,385. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. Oct. 16, 1959 [Oct. 23, 1958], No. 35065/59. Class 40 (4). In a system, like that of Specification 921,384, in which communication between an automatic satellite (non-exchange) and the main exchange is by time division multiplexing, the subscriber lines 10 are connected to a common communication link 12 between the satellite and the exchange by means of individual two-way line gates 21 which are enabled cyclically by enabling pulses, the lines being grounded between enabling pulses by the common circuit 24. As shown each line 10 is connected by way of a repeat coil 23 to a low-pass filter 22, a resonant transfer inductance 31 permitting lossless transfer of the information stored in the shunt capacitor 32, terminating the filter 22, through the line gate 21 to the link 12. A free time slot having been allocated to the line shown, an enabling pulse is applied in that time slot to the base of transistor 34 in its line gate 21, whereupon the gate is opened and transfer occurs between capacitor 32 and the corresponding capacitor of the called line circuit. The common gate 24 being blocked at this time, the enabling pulse does not appear on the line 10, but passes via resistor 25 to ground. At the end of the enabling pulse the line gate 21 returns to its high-impedance state and a pulse simultaneously applied to the base of transistor 35 enables the gate 24 thus effectively grounding the lower plate of capacitor 32 in all the line circuits to render them unbalanced preparatory to the storage of new information on the capacitors 32. The gate 24 may be replaced by the passive network shown in Fig. 4 which effectively grounds the lower plates of capacitors 32 except during the line gate enabling pulses.

Title: Improvements in rubber or like spring devices
IPC: F16F1/393
Filed: 1936-12-21
Abstract: 489,369. Resilient mountings. PIRON, E. H. Dec. 21, 1936, No. 35067. [Class 108 (iii)] A spring device comprises concentric loadimposing and load-receiving members, e.g. a shaft 1 and base 4 having alternate concentric metal cylinders 3 ... 3d and rubber cylinders 2 .. 2c therebetween, stop means being provided for limiting progressively the shear deflection axially of the device when loaded. As shown in Fig. 1, flanges 6 on the metal cylinders successively contact during increasing load with the stepped portions 14 .. 14c of a stop-plate 8 fixed to the shaft 1 thus successively rendering inoperative the corresponding rubber cylinders. The cylinders are formed in two parts, Fig. 2, the rubber segments being moulded or otherwise surface bonded to the metal segments, the edges of co-operating pairs of which are separated by the rubber. Each rubber cylinder decreases in height from its inner to its outer surface and the mean height of the cylinders decreases outwardly of the spring. To vary the characteristics of the spring, caps may be scrawthreaded on the flanges 6 or the flanges may be fitted with plain or flanged shims. Alternatively each stepped portion of the plate 8 may be adjustable by screws 11, Fig. 5, and moreover the position of the plate 8 may be altered by central adjusting means 12. In a modification the rubber cylinders are cut-away at their under surfaces.

Title: Process and apparatus for removal of water during hydrocarbon oxidation
IPC: C07C29/52
Filed: 1962-09-14
Abstract: A process for removing water during the oxidation of hydrocarbons with a molecular oxygen containing gas in an oxidation zone, preferably in the presence of a boron compound, e.g. meta boric acid, comprises withdrawing a gaseous effluent containing unreacted hydrocarbon and water from the oxidation zone; intimately contacting the gaseous effluent with a relatively cool liquid stream of the hydrocarbon; a portion of the unreacted hydrocarbon from the gaseous effluent being condensed in the liquid stream; introducing the condensed hydrocarbon and the liquid hydrocarbon into the oxidation zone; condensing the remaining uncondensed hydrocarbon and water in the gaseous effluent; phase separating the condensed water and hydrocarbon; and recycling the last-mentioned condensed hydrocarbon as the aforesaid relatively cool liquid stream.  In an example, to a batch oxidation reactor 1, charged with meta boric acid and cyclohexane, and maintained at a temperature of about 330 DEG  F. and a pressure of 120 p.s.i.g. air is introduced through line 5 and about 77 parts of O2 absorbed.  About 8% of the cyclohexane reacts and the liquid reaction mixture is withdrawn through line 6, and treated to recover the hydrocarbon oxidation product (largely cyclohexanol). Heat is supplied to the reactor through means 7 and a high boil-up is maintained and the vapours removed from the reactor through line 8 contain cyclohexane, water and nitrogen, which are passed to a contacting tower 2 where the hot vapours are brought into direct contact with cold recycle liquid cyclohexane containing phased water introduced into the contacting tower 2 through line 9 at a temperature of about 100 DEG  F.  The contact of the two streams results in (1) the condensation of cyclohexane and the cooling of the remaining vapours which leave the top of the contacting tower 2 through line 13, and pass to condenser 3 wherein essentially all of the cyclohexane and water are condensed. Non-condensible gases, e.g. nitrogen, are removed via line 14.  This stream contains cyclohexane vapour which may be recovered in a subsequent scrubbing operation; (2) the heating of the cyclohexane liquid to about 310 DEG  F., which is withdrawn from the contacting tower 2 through line 10 and contains essentially water-free cyclohexane which is passed back to the oxidation reactor 1 wherein it may undergo further reaction, and (3) the stripping out of the phased water from the liquid recycle stream, by passing the cyclohexane water condensate to phase separator 4. Specification 996,791 is referred to.

Abstract: 988,417. Yarn packages. ALGEMENE KUNSTZIJDE UNIE N.V. Sept. 5, 1963 [Sept. 20, 1962], No. 35188/63. Heading D1D. [Also in Division B8] A yarn package 4 is wound on a bobbin 3 and two distinct bundles 8, 11 are wound one at either end of the bobbin, the lower bundle 8 serving to secure a transfer tail wound under the bundle and the upper bundle 11 including the starting end of the thread which is secured against the bobbin by a removable clamping device. With the bobbin 3 mounted on a spindle 1 in a draw-twisting machine and with a ring traveller in the position a an initial waste portion 6 of yarn is wound on the spindle 1. The ring is raised to position b forming a loop 7 which passes over the transfer rim 2 and further turns 8 are wound at the lower end of the bobbin before the ring is raised to the position c leaving about three spaced turns 9 wound about the bobbin. The ring is traversed in the normal manner between positions c and d to build a package 4 and then raised to position e to form the upper bundle 11. The cycle of operations is complete by lowering the ring to the position a thereby forming a steeply inclined turn 12. The turn 12 is cut at the point where it crosses an annular groove 13, the tail end 15 placed in the bore of the bobbin and a removable clamping device (Figs. 3, 4, and 5 not shown) placed on the end of the bobbin to hold the end 15. The wound bobbin is next doffed, in the course of which the loop of yarn 7 catches in a notch 14 in the transfer rim and becomes severed thereby, leaving a short tail of yarn extending from under the bundle 8. Axial grooves 19 in the lower end of the bobbin facilitate cutting through the bundle 8 to leave the turns 9 available for piecing to another package.
