Title: Improvements in or relating to submarine signalling cables
IPC: H01B7/14
Filed: 1930-03-03
Abstract: 349,642. Cables. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Wentz, J. F. ; 425, Bedford Avenue, Mount Vernon, New York, U.S.A.) March 3, 1930, No. 6959. Convention date, April 18, 1929. [Class 36.] In order to protect the guttapercha core of submarine signalling cables from the attacks of teredos and other submarine borers with a material which will offer great resistance to the passage of eddy currents, the guttapercha core is wound with fabric or rubber tapes impregnated with fine particles of metals, alloys or minerals incorrodible by seawater. A cotton tape impregnated with copper particles and some binder such as shellac or lacquer may be used, or tapes may be impregnated with fine particles of quartz. A thin metallic layer may be sprayed or deposited directly on the guttapercha core, or metallic or other particles may be mixed with guttapercha and extruded directly on the outer layer of the guttapercha core. In the embodiment, a guttapercha core 12 enclosing a signalling cable 10, 11 is helically wound with overlapping turns with a fabric or rubber tape 13 which is impregnated with a mixture of copper powder in shellac. Armouring 14 is laid on a filler 15 over the tape 13.

Title: Manufacture of emetine
Inventor: OPPENSHAW HARRY TACON
IPC: C07D455/08
Filed: 1959-11-24
Abstract: Emetine is prepared by condensing 3-ethyl-1,2,3,4,6,7 - hexahydro - 9,10 - dimethoxy - 2 -oxo - 11bH - benzo(a)-quinolizine with a (lower alkoxymethylene)-triaryl phosphorane to give 2 - (lower alkoxymethylene) - 3 - ethyl - 1,2,3,4,6,7-hexahydro - 9,10 - dimethoxy - 11bH - benzo(a)-quinolizine, catalytically hydrogenating the latter, preferably under acid conditions, to give 2 - (lower alkoxy carbonyl methyl) - 3 - ethyl -1,2,3,4,6,7, - hexahydro - 9,10 - dimethoxy - 11bH -benzo(a)quinolizine, converting the product into the homoveratrylamide, cyclizing the latter to give O-methyl psychotrine, and reducing this compound to emetine.  (-) Emetine is thus prepared starting from (-) 3-ethyl-1,2,3,4,6,7,-hexahydro - 9,10 - dimethoxy - 2 - oxo - 11bH -benzo(a)quinolizine, which is obtained by treating the racemic ketone with one equivalent of (-)-camphor 10-sulphonic acid in a solvent from which the (-) camphor-10-sulphonade may be separated, after which the other enantiomer is racemized by mild heating to give further amounts of the desired optical isomer.  The 3 - ethyl - 1,2,3,4,6,7 - hexahydro - 9,10 - dimethoxy - 2 - oxo - 11bH - benzo(a)quinolizine is itself prepared by treating 1,2,3,4-tetrahydro-6,7-dimethoxy-isoquinoline with an N-halogenating agent, then heating with alkali, and treating the resulting 3,4-dihydro - 6,7 - dimethoxyisoquinoline with an acid addition or quaternary salt of a Mannich base derived from a secondary amine, formaldehyde and from pentan-2-one or 2-ethyl-3-oxobutyric acid.  Isoemetine, obtained as a by-product during the reduction of O-methylpsychotrine is recycled by reconversion to O-methylpsychotrine isolated as the dihydrogen oxalate salt by treatment with an N-halogenating agent and alkali. The process is illustrated by detailed examples. 1,2,3,4-Tetrahydro-6,7-dimethoxyisoquinolin is prepared from 3,4-dimethoxyphenylethylamine and paraformaldehyde. The corresponding carbonate salt is also mentioned.  The oxime of 3-ethyl-1,2,3,4,6,7-hexahydro - 9,10 - dimethoxy - 2 - oxo - 11bH -benzo(a)quinolizine is prepared from the parent oxo compound. Specifications 828,999, 999,092, 999,093, 999,094 and 999,095 also are referred to.

Filed: 1941-06-19
Abstract: 548,572. Aircraft wings. ELLIOTT, A. June 19, 1941, No. 7746. [Class 4] [Also in Group XXII] The metal coverings of the wings, tail planes, flaps and like parts of aircraft, or other framed structures covered with sheet metal, are stiffened where necessary by means of channels, depressed therein, which are completely closed at the surface of the covering or have gaps which are small compared with the crosssectional dimensions of the channels, at least one of the channels being of a different length of metal in cross section, at one part of its length than at another in order to shape the covering. A wing is described in which the covering is formed with parallel longitudinal channels pressed in from the surface and of open rectangular or dovetail form or of the shapes shown in Figs. 5, 6, and 7. The channels may hold nuts or tapped strips for use in securing the covering to the ribs, or the channels may be filled with plastic and the gap closed before the plastic has set. Where the covering crosses a spar, the channel may be bent over and flattened or the metal may be slit at those places so as to form a flat lap joint when the channels at opposite ends of the slit are formed. Fig. 11 shows a tool for forming a rectangular channel, the metal sheet 30 being moved by lower and upper blocks 28, 29 against a former 31, lateral movement of the blocks being effected by links 34 and sloped surfaces 33. To form a closed channel, undercut grooves are formed in the upper blocks 29 and the former 31 is removed before the blocks are completely pressed together laterally.

Title: Centrifugal fuel pumps
IPC: F04D9/00
Filed: 1956-03-13
Abstract: 786,705. Centrifugal pumps. NASH ENGINEERING CO. March 13, 1956 [March 29, 1955], No. 7875/56. Class 110 (1). A self-priming centrifugal fuel pump comprises two contiguous merging pumping chambers in which the opposite halves of a doublesuction impeller are respectively contained, widely spaced inlets to the respective chambers at opposite sides of the impeller, vacuum pumping means connected separately to the chambers for removing air and vapour from each chamber independently of the other chamber, a common discharge port for the two chambers, and a spring-loaded valve which closes the discharge port when the delivery pressure falls below a predetermined value so as to retain a sealing ring of spinning liquid at the junction of the chambers on failure of the supply of liquid at the inlets of both chambers. An electrically driven pump mounted within an aircraft fuel tank comprises a centrifugal impeller 24 having a partition 37 which divides the pump into an upper chamber 28 and a lower chamber 30 discharging to a common volute 32. Chamber 28 is connected to an intake 34a near the top of the tank and chamber 30 is connected to an intake 36a near the bottom of the tank. The lobe 42 of a liquidring priming pump 26 is connected by a duct 40 to an annular groove 38 in the chamber 28, and the other lobe 42a is connected by ducts 50, 48, 46 to an annular groove 44 in the chamber 30, so as to remove air and vapour independently from the two chambers. If both inlets 34a, 36a are, as shown, temporarily uncovered by fuel during abnormal flight conditions, the resultant fall in discharge pressure causes a spring-loaded discharge valve 70 to close, so that a ring 90 of revolving liquid is maintained in the chambers 28, 30 to keep the chambers sealed off from one another. If one of the inlets becomes covered again, the corresponding half of the impeller resumes pumping and the valve 70 opens; the ring 90 is maintained in the inoperative half and preserves the seal between the chambers 28, 30. If both inlets 34a, 36a remain uncovered long enough to permit dissipation of the ring 90 and the liquid ring of the priming pump 26, mere covering of an inlet 34a or 36a does not restore pumping, and it is then necessary for an inlet to be submerged sufficiently to allow the liquid level to just reach the lower tips of the impeller blades. A portion of the first liquid to reach the blades is then thrown outward to re-establish the ring 90, and another portion is impelled into the priming pump 26 to re-establish the liquid ring. The pump may be mounted at an angle or horizontally, and the inlets can be directed to different parts of the tank. If the pump is used as a booster pump with its discharge 58 connected to the suction of a main pump, a bypass valve 82 is provided to permit the main pump to draw directly from the tank if the booster pump fails and to prevent the main pump from sucking the valve 70 into the open positior. Specification 724,652 is referred to.

The top of the vessel is closed by a cover 3 and suction or compressed air supplied through a pipe 2 causes the oil to pass out through the filter and pipe 7. The filter element may be cleaned by a scraper embracing the contact of the element and rotated by means of a handle outside the vessel.
