Patent GB-706723-A (GB)
Title: Process for the production of carboxylic acid amides or thioamides
Filed: 1951-10-09
Abstract: Carboxylic acid amides or thioamides are manufactured by heating a 1-nitro-olefine-1 with an ammonium polysulphide solution or with sulphur and anhydrous ammonia or a primary or secondary amine, advantageously in the presence of an organic solvent.  When using an ammonium polysulphide solution or sulphur and anhydrous ammonia, the reaction should be effected at elevated pressure. The nitro-olefine, which advantageously contains not more than six carbon atoms in the molecule, may be first prepared by condensing nitromethane with an aldehyde, which is thus converted to an amide or thioamide containing one more carbon atom in the molecule.  In examples: (1) 1-nitropentene-1 (obtainable from nitromethane and n-butyraldehyde) is heated in a sealed tube with ammonium polysulphide solution and pyridine to produce pentanamide; (2) b -nitrostyrene (obtainable from nitromethane and benzaldehyde) similarly yields phenylacetamide; (3) b -nitrostyrene is refluxed with sulphur and morpholine to produce phenylthioacetomorpholide, which is hydrolysed with dilute sulphuric acid to phenylacetic acid.  Specification 607,765 is referred to.
Patent GB-322805-A (GB)
Title: Improvements in radio direction indicators
IPC: G01S1/02
Filed: 1928-08-16
Abstract: 322,805. Antranikian, H. Aug. 16, 1928. Directive signalling; controlling signalling- apparatus.-In directive reception the windings of two fixed loop aerials 1, 2, preferably set at right-angles, and connected in series and tuned by the same condenser 3, are periodically reversed by means of a rotating switch 8 so that one or other of the frames is alternatively effective. A coupling-transformer in the output of the amplifier A comprises primary windings 9, 10 set at right angles, and rotatable secondary windings 11, 12 set parallel to each other. The primary windings-may be connected in series or in parallel, and the connections are reversed by a switch 8<a> simultaneously with those of the loop aerials. The direction of a transmitting station is then indicated by the position of the windngs 11, 12 whch gives equal strength of signal on both sides of the reversing switch. This indication may be given by a telephone or by an electromagnetic relay 17 mounted in a Wheatstone bridge and set across a third reversing-switch 8b. For automatic operation, the relay 17, Fig. 4, is polarized so that one or other of the contacts are closed according as the signal strength is greater for one setting than the other as the reversing switch changes over. This in turn energizes through an amplifier 18 a second relay 19 which controls the direction of rotation of a motor 20. The latter rotates the movable windings 11, 12 until the relay comes to rest, thereby indicating the direction of the incoming signals. The apparatus may be used to guide an aeroplane at a constant angle relatively to a transmitting station. In order to avoid positions of zero pick-up in one or other setting of the reversing switch, both the loop aerials 1, 2 and the coupling transformer 9 - - 12 may be rotated electrically through an angle of 45‹, without bodily movement, by a. system of multiple loops or windings and suitable switches. Correction for quadrantal error may be applied automatically by means of a suitably-shaped cam 24, Fig. 7, driven from the shaft 22 carrying the movable windings 11, 12 and engaging one end of the indicator needle, as shown.
Patent GB-461895-A (GB)
Title: The manufacture of compounds of the cyclopentano polyhydro phenanthrene series
Filed: 1935-08-22
Abstract: Keto - cyclopentanodimethyldodecahydrophenanthrol is prepared from an unsaturated pregnanolone by treatment with a metal organic compound according to Grignard followed by dehydration and oxidation of the product, the double bond in ring 2 and the hydroxyl group in ring 1 being intermediately protected during the oxidation.  The preferred method of protection of the nuclear double bond is by halogenation, which may be done either before or after the Grignard reaction.  If the doubly unsaturated alcohol formed by the dehydration of the Grignard reaction product is halogenated, the halogen only adds on to the nuclear double bond, and not to the double bond in the side chain, which thus remains free for the subsequent attack of the oxidizing agent which is preferably ozone.  As agents for the protection of the hydroxyl group there may be used esterifying, etherifying or halogenating agents.  After the oxidation, the splitting of the ozonide, and the removal of halogen with re-establishment of the nuclear double bond is preferably effected in one operation, for example by zinc dust and glacial acetic acid. Specification 449,326 is referred to.  A sample has been furnished under Sect. 2 (5) of the acetate of keto-cyclopentanodimethyldodecahydrophenanthrol prepared from pregnenol-(3)-one-(20) thus: methyl magnesium iodide is allowed to react with pregnenol-(3)-one-(20), and the product heated with glacial acetic acid for 5 hours.  The doubly unsaturated alcohol thus obtained is acetylated on position 3 by heating with sodium acetate and acetic anhydride, and oxidized with ozone after bromination of the nuclear double bond.  The ozonide is split, and halogen simultaneously eliminated from the nucleus by treatment with zinc dust and glacial acetic acid to give the required product, which may, if desired, be saponified to the corresponding keto-alcohol.

Title: Curved extrusion process and apparatus
IPC: B29C53/12
Filed: 1953-08-27
Abstract: 732,091. Making curved channel members from thermoplastic material. FISCH, R. A. Aug. 27, 1953, No. 23731/53. Class 87 (2). Curved strip of thermoplastic material channel-shaped in cross-section, is produced by extruding the material R downwards through a die 20 with a channelforming orifice, rotating a supporting member 30 having a flange 31 adapted to fit snugly into the channel of the extruded strip, cooling the strip along the path followed by the periphery of the supporting member and withdrawing the cooled, set and curved strip before it has completed more than three-quarters of a revolution on the supporting member. The strip leaves the die in a downward direction to minimize the tendency for the soft flanges of the channels to become disturbed by gravitational forces. The die is preferably heated, a suitable temperature being 250‹-300‹ F. The member 30 is mounted to rotate freely, and the strip is pulled round by a pair of rollers 41, 42 with peripheries which fit into one or more grooves in the strip. To retain the curvature the peripheral speed of the outer roller 42 must be slightly higher than that of the inner roller 41, either by rotating it faster or giving it a larger diameter. A suitable speed is one which draws off the strip at about 35 feet per minute. The channel in the extended strip is forced to straddle the rotating flange 31 by a jig 40, which may be stationary or may be a rotating wheel. The cooling is effected by passing the strip through water or other cooling liquid 65, with a thermostat heater to keep it at a constant temperature, suitably 110‹ F. Alternatively, jets of cooling gas may be used. The temperature of the material is such that any liquid on the flange 31 would vaporize and distort the product, and the level of the liquid must therefore be below the point where the strip meets the rotating flange and any liquid carried round by the flange must be removed, which may be done by forcing dry air through a jet 67. The configuration of the rotating member 30 may be other than circular, e.g. elliptical. The strip leaving the rollers 41, 42 may be led into a container which is rotated so that the strip is deposited in it in the form of a helix. The product finds use as a rim insulating shield in a cathode ray tube.

Abstract: 1,236,689. Semi-conductor devices. NIPPON ELECTRIC CO. Ltd. 9 May, 1969 [16 May, 1968], No. 23853/69. Heading H1K. In a Gunn-effect device destructive heat development adjacent the anode is prevented by providing a greater cross-section of semiconductor material adjacent the anode than elsewhere in the active region of the device. In Fig. 3 this is achieved by etching a groove in a N-type GaAs layer 13 on a semi-insulating GaAs substrate 12 between the two Au/Ce/Ni electrodes 14, 15. In Fig. 4 the same effect is obtained by etching an N-type GaAs layer of uniform thickness to leave a T-shaped portion 17 between the electrodes 18, 19. The increased cross-section may be provided adjacent both electrodes. A prior art arrangement is described in which N+ + GaAs regions (8, 9), Fig. 2 (not shown), are selectively grown by liquid phase regrowth at each end of an N-type region (6) covered with a SiO 2  layer (7). Metal electrodes (10, 11) are then positioned on the N+ + regions (8, 9).

Title: Four course beacons for radio navigation
IPC: G01S1/02
Filed: 1939-08-18
Abstract: 532,173. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd. Aug 18, 1939, No. 23881. Convention date, Sept. 30, 1938. [Class 40 (v)] A four-way navigational course is radiated from three dipoles set at the apices of an isosceles triangle, the centre dipole being constantly energized, whilst the other two are alternately controlled by a keying device which is located outside the field of the carrier current and shortcircuits the appropriate feed-line. Means are also provided to avoid the production of " key-clicks " when the beacon is in operation. As shown in Fig. 1, the centre dipole 2 is constantly energized from a feed-line 4, and is also coupled to the dipoles 1, 3 by feed-lines 6, 5. The latter are alternately short-circuited by a common keying- device 9 in A-N rhythm, one line being broken before the other is made. The junction points A, B are each a quarter-wave distant from the dipole 2, the feed-lines 5, 6 are each a half-wave long, and the keying-lines 7, 8 are a quarterwave long. Thus when the line 7 is short-circuited its impedance is infinite, and energy is transmitted from the dipole 2 along the feeder 5 to the dipole 3, which then radiates in phase-opposition to the dipole 2, giving the dash-dot figureof-eight field shown in Fig. 2. Meanwhile the line 8 is open-circuited, and its impedance is zero, so that no energy reaches the dipole 1 from the line 6. Similarly when the line 8 is shortcircuited, the radiation pattern is the solid-line, figure-of-eight curve shown in Fig. 2. Between the keying periods, the dipole 2 radiates a uniform field in all directions, as shown by the dotted-line circle, the field intensity being equal to that along either of the four course-lines. In a modified arrangement, the feed lines 5, 6 are " crossed," the radiation pattern then being similar to that shown in Fig. 2 but differently phased. The course-lines may be radiated at different angles and at varying strengths.

Abstract: 837,500. Liquid fuel burners. CLEAVERBROOKS CO. July 29, 1957, No. 23956/57. Class 75(1) In a method of purging an oil nozzle and supply line on shutting down of the burner, air is introduced into the supply line at a pressure sufficient to maintain continuous oil flow in the supply line and continuous burning of the oil and the flow of air is continued until the nozzle is scoured. The air is introduced at a pressure equal to the pressure of oil in the supply line immediately before shut-down. Oil from a bulk source passes via a strainer 17 to a pump 18, thence through a preheater 20 to a metering valve 27 from which it passes by a short stump line 28 and a solenoid controlled main valve 29 to the supply line 12 to the nozzle 10. Air passes from an intake 35 by way of a compressor 37, air receiver and lubricating oil strainer 39 and a line 15 to the housing 11 of the nozzle The receiver 39 is also connected via a line 42 having a restricted orifice 43, a control valve 41 and check valve 44 to the oil supply line 14 connecting the valve 29 with the line 12. When the valve 29 is closed, the valve 41 is opened causing a brief surge of air whereafter the air pressure falls to the same pressure as that at which the oil was flowing just before shut-down and continues for a short period. Where the burner is used for steam generating, the preheater 20 may be initially heated by electrical means under the control of a thermostat and after sufficient steam pressure is built up, steam admitted by a solenoid valve 23 may be substituted for the electrical means.
