Title: Improvements in or relating to flying boats or ships
IPC: B64C3/38
Filed: 1929-09-14
Abstract: 339,687. Lewis, J. N. Sept. 14, 1929. Aeroplanes; planes, connecting to machine; fuselages; propelling; controlling.-A flying boat hull has a central longitudinal truss b, Fig. 2, extending substantially from nose to stern and carrying means extending both sides of it for detachably securing to inner rods of wings k, k<1>. Fig. 3. The hull a which is wholly enclosed comprises a sheet metal envelope with or without a wood covering. The centre truss b is braced at intervals by cross trusses i. Pairs. of wings, k, k<1> have square bosses l, Fig. 4, adapted to turn in bearings m to change their angle of incidence. This is effected by means of a cylinder n, carried by the, centre truss, into the ends of which the bosses l are spigoted and secured by bolts s. The cylinders are rotated by worms p and worm wheels o, the worms p being on a common shaft. Alternatively hand wheel and cable may be employed but in either case the controls are carried in a forward glazed cabin z, Fig. 3. After removal of bolts s the wings may be jettisoned by the action of plungers r which when fluid under pressure is admitted to the space, between their heads drive, out the bosses l, entering the holes through which the bosses passed and sealing them. Alternatively, mechanical means may be employed. Airscrews e, Fig. 2, are driven from an engine, or engines within the hull. A water propeller t and water rudder v are fitted, also a centre board x which may serve, as a stabilizing fin being lowered or retracted during flight.

Filed: 1924-11-24
Abstract: 230,757. Galland, J. Oct. 21, 1924, [Convention date]. Hand-trucks.-A truck for lifting the fuselage of an aircraft to enable it to be manoeuvred on the ground comprises a pair of wheels 1 connected by a cranked axle 2 carrying a framing 3, a trough 6 carried by a shaft 5 adapted to slide in guides 4 pivoted to the axle 2 to raise the fuselage after its support has been engaged by the trough 6, and means for raising the trough. The raising means comprises cables 10 wound upon drums 11 on the framing 3 and connected to chains 7 which pass over pulleys 9 and around the guides, their ends being secured at 8. The drums 11 are actuated through worm gearing 14 by a hand-wheel 13 the shaft of which is pivoted at 16 to the framing 3 to permit the wheel to be disconnected from the drums.

Title: 11ª‡-hydroxy-11:19-cyclo-steroids and 19-oxygenated steroids and process for their manufacture
IPC: C07J75/00
Filed: 1962-07-20
Abstract: The invention comprises (1) a process for the preparation of 19-oxygenated steroids wherein a 19-unsubstituted 11-oxo-steroid that contains a free oxo group only in position 11 is irradiated with ultra-violet light in a solvent, an 11a -hydroxy-11,19-cyclo-steroid formed is treated in an inert solvent with an oxidizing heavy metal acylate, in any resulting 11-oxo-19-acyloxy-steroid obtained the cyloxy group is hydrolysed and, if desired, an 11-oxo-19-hydroxy-steroid formed is oxidized to an 11,19-dioxo-steroid or an 11-oxo-steroid-19-acid; and (2) as new compounds, the 11a -hydroxy-11,19-cyclo-steroids which are intermediates in this process, and their esters.  Suitable acylates for use in the process are lead tetra-acylates, and in most cases the 11-oxo-19-acyloxy-steroids formed undergo hydrolysis even on chromatography on alumina, but they can also be hydrolysed with bases, e.g. with an alcoholic alkali metal hydroxide.  Oxidation of the 11-oxo-19-hydroxy steroids with chromium trioxide in basic solution yields 11, 19-dioxo-compounds while in acid solution the 11-oxo-steroid-19-acids are obtained. The steroids used in the present process may be of the androstane, pregnane, cholane, cholestane, spirostane or cardanolide series and may contain as substituents ketalized oxo groups or oxo groups converted into enol derivatives, free, esterified or etherified hydroxyl groups, alkyl, alkenyl or alkynyl groups of halogen atoms in one or several of positions 1, 2, 3, 4, 5, 6, 7, 8, 9, 12, 14, 15, 16, 17, 18, 20, 21, 22 and 23.  They may also contain double bonds, for example in positions 5, 6, 13 and 16, or oxido groups. Ketalized oxo groups may subsequently be released.  Examples are given.

Title: Improvements in or relating to amplifiers with negative feedback
IPC: H03G5/08
Filed: 1946-09-20
Abstract: 634,096. Valve amplifying circuits. PHILIPS LAMPS, Ltd. Sept. 20, 1946, No. 28253. Convention date, March 4, 1943. [Class 40 (vi)] In a negative feedback amplifier the feedback circuit includes a network having a frequency-variable transmission factor # to vary the gain with frequency, and the output circuit of the amplifier valve includes a network such that the amplification factor #1 of the valve and the output network satisfies the condition ##1 is real and constant. As shown, an amplifier valve 1 is coupled to a further amplifier stage 3 through an impedance Z1, small relative to the internal resistance of valve 1. A negative feedback network comprising impedances Z2, Z3 is connected between the output and the cathode of valve 1, the feedback voltage being taken across Z3 only. The condition ##1 real and constant is satisfied if Z1, Z3 and Z2+Z3 are both constant. The second condition may be fulfilled by forming the impedances Z2, Z3 of impedances Z2<1>, Z3<1> respectively, each shunted by a resistance R, where Z2<1>, Z3<1>=R<2>. The impedance Z2 may be formed of a resistance large compared to Z3, and the resistance R shunting Z3<1> omitted.

Title: An improved method of purifying commercial benzene
IPC: C07C7/148
Filed: 1924-11-27
Abstract: Commercial benzene is purified and render stable to light and air by heating to 100-250 DEG  C. under a pressure below 100 atmospheres of air or other gas or at 250-500 DEG  C. without pressure.  The process polymerizes the unsaturated constituents and destroys carbon disulphide and hydrocyanic acid, but leaves the thiophenes. Catalysts such as water, acids, alkalies, metals, or metallic oxides or other compounds may be used to vary the nature of the polymerization residues, a part of which may be obtained in the liquid form by distillation, leaving neutral pitch as a final residue.  Lighter coloured residues are obtained by lining the apparatus with lead, tin, or copper, or by adding these metals or their oxides to the oil.  In an example crude benzene with a washing loss of 4.65 per cent is heated for 2 hours to 150 DEG  C. under a pressure of 20 atmospheres, and the product distilled up to 120 DEG C.  The 97.5 per cent passing over has a washing loss of 2.2 per cent.  The residue is mostly thiophene.  The Specification as open to inspection under Sect. 91 (3) (a) comprises the treatment of crude benzenes by heating for a short time to a high temperature, e.g. 150-400 DEG  C., with or without pressure, e.g. 25-75 atmospheres, and with or without a catalyst to vary the nature of the polymerization residues.  This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Specifications 123,806 and 223,066.ALSO:Commercial benzene is purified and rendered stable to light and air by heating to 100-250 DEG  C. under a pressure below 100 atmospheres of air or other gas, or at 250-500 DEG  C. without pressure.
