Title: Improvements in relay apparatus for detecting current changes in railway track circuits
IPC: B61L1/18
Filed: 1935-01-24
Abstract: 431,556. Track relay apparatus. GENERAL RAILWAY SIGNAL CO., Rochester, New York, U.S.A.-(Assignees of Field, O. S. ; 473, Seneca Parkway, Rochester, New York, U.S.A.) Jan. 24, 1935, No. 2433. Convention date, Feb. 15, 1934. [Class 105] [See also Group XXXVII] A relay combination to obtain substantially the same pick-up and fall-away values of current for a track relay apparatus and a longer pick-up time than fall-away time comprises a primary relay P of the tractive type connected to the track circuit and energizing over front contact 10 a secondary relay S to reduce the magneto-motive force of the primary relay, the secondary relay being made slower to pick up than to fall away, for example, by saturable magnetic laminae 13 joining the legs thereof and so serving to divert the flux from the armature 7 until the flux reaches a certain value, the building up of the flux being retarded by copper slug rings 12. The reduction of the magneto-motive force of the primary relay P is effected by the front contact 7 of the secondary relay S causing only a part 5 of the winding of the primary relay P to be in circuit and by inserting a resistance 6. The contact 7 is a make-before-break contact. Specification 344,214, [Group XXXVII], is referred to.

Abstract: 1,124,301. Fuel injection pumps. C.A.V. Ltd. Jan.5, 1966 [Jan. 20, 1965], No. 2439/65. Heading F1A. In a rotary cylinder distributer type fuel injection pump radial inlet bores 23 (not shown) in the distributer communicate successively at equal intervals with an inlet port 24 connected through a throttle to the outlet of a feed pump 12. At other times when outlet bore 21 is in communication with one of the delivery ports 22 the bores 23 successively communicate with a port 26 connected to a cylinder housing a shuttle 27. Grooves 30 alternate with the bores 23 and connect the port 26 through a throttle valve 33, variable in accordance with the feed pump outlet pressure, to the inlet of the feed pump. The shuttle 27 has an adjustable stop 29 and is biased inwardly by a spring or as shown by feed pump pressure from passage 28. During each discharge stroke of the pistons 17 a volume of liquid flows into the cylinder 25 and is subsequently discharged to the feed pump inlet by the return movement of the shuttle 27, which movement is regulated by the valve 33. A stop valve in passage 28 or 31 prevents movement of the shuttle 27 and hence provides excess fuel for starting.

Title: Improvement in colloidally dispersed material and method of making the same
IPC: C09D17/00
Filed: 1926-02-01
Abstract: 246,874. Cabot, S. Jan. 31, 1925, [Convention date]. Incorporating paint ingredients.-Colloidal dispersions of solids in non-solvent media are made by kneading the solid with a gel substance which is used in such a small proportion as merely to suffice to film coat the ultimate particles of the solid, the kneading being carried out to yield a stiff plastic sticky paste. A quantity of the dispersing medium just sufficient to convert the colloid from a hard to a soft gel condition may be used in the kneading operation. The invention is particularly applicable to the dispersion of inorganic pigments, in organic liquids, and may be employed in the preparation of paints. In an example, one part of linseed oil jelly (containing about 30 per cent of turpentine) is kneaded with three parts of a pigment, such as a combination of titanium oxide and barium sulphate, and the resulting sticky plastic mass is mixed with one part of linseed oil and sufficient turpentine and drier to make a workable paint. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use with liquid hydrocarbons and animal and vegetable oils as dispersing media, of drying or semi-drying oils, which have been polymerized by heat treatment or oxidized by blowing, rubber, or fossil gums, as protective colloids; and for an alcoholic medium, Manilla gum or cellulose nitrates or acetates may be used. The invention is also stated to be applicable to stains, varnishes, &c. This subjectmatter does not appear in the Specification as accepted.

Title: Process for preparing d-ribose
Inventor: SUGASAWA SHIGEHIKO
IPC: C25B3/25
Filed: 1964-01-23
Abstract: D-ribose is prepared by electrolysis of D-ribonolactone, held in a catholyte including an ammonium salt of an inorganic acid, and which is separated from the anolyte by a porous membrane, the cathode consisting of mercury. The anolyte consisting of a dilute solution of H2SO4, HCl, or H3PO4 is contained in a cup e.g. of unglazed porcelain or alundum, which permits H ions to flow to the catholyte but not the diffusion of the catholyte liquid. The anode is of lead, platinum, graphite, or a PbO2 coating on lead.  Ammonium halides, sulphate, or phosphate may be used in the catholyte to form a 5% solution, and small amounts of an inorganic acid are added to it from time to time to maintain the pH value at 3-4. The reaction is cooled to maintain temperature below 20  DEG C. The catholyte is neutralized, concentrated at reduced pressure, and below 40  DEG C., and the syrup produced seeded with D-ribose to induce crystallization.

Filed: 1943-02-23
Abstract: 564,517. Injectors &c. NEWCOMBE, C. K. Feb. 23, 1943, No. 2988. [Classes 8 (i) and 71] [Also in Group XXVI] The plant comprises a primary air compressor supplying a combustion chamber wherein fuel is burnt, the products being used in a jet-type air compressor to entrain further air and exhaust gas from a gas turbine or engine and the resulting mixture fed to the gas turbine or other engine. Exhaust gases from the turbine may be used to generate steam for a second jet compressor which supplies the compressor before the combustion chamber. The steam may be condensedin the last-mentioned compressor and the water returned to the steam generator. Fig. 1 shows an opposed piston two-stroke diesel engine 5 coupled by beams 6 to an air compressor 7 which supplies a combustion chamber 9. The products of combustion issue from a nozzle 11 and entrain air, or exhaust gas, from a pipe 14, and the whole led to a gas turbine 18. Some of the exhaust gas from 18 may be led to the pipe 14. Both of the compressors 7 and 11 may be multi-stage. Some of the motive gas may be used to drive a jet vacuum pump to draw off the boundary layer from the walls of a diffuser 15. In Fig. 2, a highly-supercharged two-stroke diesel engine 20 has a scavenge blower 51 and a turbosupercharger 22, both of which may be operated by exhaust gases from the engine and from steam generated in a boiler 23. The engine drives a multi-stage air compressor 21 which discharges at three different compressor pressures at 24, 25, 26 to separate combustion chambers 27, 28, 29 respectively. The products of combustion are passed to a multi-stage jet compressor 30 which entrains air, and maybe some exhaust gas, and the products led to a turbine 32. Fig. 3 shows a third arrangement in which is a turbine-driven air compressor 40 supplying a combustion chamber 41, the products of combustion being passed to a jet compressor 42. The gases are then led to a turbine 44 whose exhaust gases are used in a steam generator 45. The steam is fed to a jet compressor 46 supplying the main compressor 40. The steam is then condensed and separated out centrifugally and the water returned to the generator.

Anti-coincidence valve 108, Fig. 4, biased beyond cut-off by source 100 receives on its control grid waveform, Fig. 2C, and on its suppressor grid waveform, Fig. 2E, produced by capacitor 118 in the integrator circuit of valve 107 also biased beyond cut-off. The output signal, Fig. 3B, at the anode of valve 108 is applied to the control grid of one half of valve 109 whose other control grid input waveform is Fig. 3C. When valve 109 has no signal on either grid both sections conduct and when waveform, Fig. 3C, is alone applied there is negligible effect on total conduction as decreased conduction in the first half of the valve is counteracted by increased conduction in the second half; when pulses arrive simultaneously at both grids the first half of the valve acts as an independent cathode follower and the waveform of Fig. 3D results at the input of transformer 121.
