Title: Improvements in or relating to carburetters
IPC: F02M1/02
Filed: 1941-12-02
Abstract: 553,796. Carburetters. BENDIX AVIATION CORPORATION. Dec. 2, 1941, No. 15538. Convention date, April 4. [Class 7 (iii)] An unbalanced choke valve 16, arranged to be opened by the flow of air against the action of a closing-spring 60, may also be actuated manually by a lever 54 through a catch 72, which is arranged to be released from its driving engagement with the valve when the latter is moved to its closed position, thereby leaving the valve free to the action of the spring and the air flow. The valve 16 is carried by a shaft 20 connected by a collar 32 and pins 36 to a sleeve 40, with a notch 70 in which the spring-pressed catch 72 engages, the catch being slidably mounted in a spindle 56 carrying the lever 54. When the valve is actuated manually clockwise from the open position shown in Fig. 6 to the closed position, the area 92 of the lever 54 approaches a stop 86, and further movement of the valve and sleeve 40 are prevented by contact of the edge of the valve with the conduit. Further manual actuation of the lever 54 in the same direction then moves the catch 72 out of the notch 70 to the right of the edge 93 of a gap in the sleeve 40, and the valve is then free for spring control under the action of the air flow. When the engine has warmed up, the valve can be manually opened by operation of the lever 54 in the opposite direction, the catch 72 bearing on the shoulder 93 until, when the valve is fully open, the other end 51 of the gap in the sleeve contacts with a stop pin 50, Fig. 6, whereupon the catch 72 is again moved into the notch 70.

Abstract: 529,261. Automatic firearms. LUNDBERG, B. O., and SCHWARZLOSE, W. A. E. May 25, 1939, No. 15587. [Class 119] The breech-block 1 of an automatic firearm is locked and unlocked by a striker-post 8 carrying a striker 9 and working in a helical slot in the breech-block, the striker-post being operated by a gas-operated driving-rod 5, through a buffer-spring 6. The pressure of the buffer-spring is transmitted to the striker-post through a sleeve 15 which, near the end of the rearward movement of the striker-post, strikes a fixed abutment 20 at the end of the receiver 16, thereby compressing the buffer-spring and effecting rapid reversal of the motion of the breech mechanism. The return of the breech mechanism is effected by a spring 19 which is disposed within the buffer-spring and the driving-rod in order to shorten the breech-block operating mechanism.

Title: Improvements in and relating to the handling and removal of furnace residues and other solid materials
IPC: F23J1/00
Filed: 1929-05-18
Abstract: 329,840. Ash Co. (London), Ltd., (Allen, F. B.). May 18, 1929. Ashpits. - In a disposed system for furnace residues and other solids in which the solids are accumulated under water, sufficient water is run off to leave the residue in a non-flowing condition to be controllably washed out by water discharged from mechanically oscillated nozzles. Water enters the hopper A through nozzles 25 and is kept at constant level by an overflow means 27 communicating with a sluiceway 9 by a conduit 26. Before removing the accumulated solids the supply of water to the nozzles 25 is stopped and the water is run off by means of one or more conduits 29 having a plurality of inlet openings 30 permitting water to flow upwardly from the hopper into the conduits, each of which is provided with a liquid-tight closure 31 operated by a piston. On opening the piston-controlled closures 5, the solids, now in a non-flowing condition, are washed from the sloping floor 4 of the hopper by water from nozzles 23 oscillated by motors 16, through a sizing grid 13 into the sluiceway 9 flushed away by water discharged from nozzles 10 and 11. To exclude air from the hopper when the closure 5 is open, a housing 14 with access door 15 is provided about each grid 13.

Abstract: 585,476. Pressure-regulating valves. EVERED & CO., Ltd., and PINKESS, L. H. Aug. 17, 1944, No. 15689. [Class 135] In a diaphragm-actuated pressure-regulating valve having an annular valve seat removable through the aperture in the valve casing normally closed by the diaphragm, the valve seat is held in place against an annular ledge in the valve casing by an annulus or short tubular member of wire gauze which also forms a filter for the fluid passing through the valve. As shown in Fig. 1, a diaphragm 7 which carries a valve spindle 5 has marginal stiffening washers 7a which are clamped against a shoulder 6a in the valve casing by a cover 10a. The washers 7a overhang the aperture 6b in the casing so as to form a seat for a metallic ring 14 of angle section furnished at the upper end of the wire gauze member 9. The lower end of the latter is soldered or otherwise secured to an annular seat 8 pressed against a ledge 6c in the valve casing. The ring 14 extends above the shoulder 6a when unstressed. In a modification with differential diaphragms, the gauze member 9 is retained by the marginal part of the smaller and inner diaphragm. In this case, both diaphragms are secured at their edges by means of rings and screwed pins.

Abstract: 799,943. Refining iron. BRITISH OXYGEN CO., Ltd. May 22, 1957 [May 22, 1956], No. 15788/56. Class 72 [Also in Group XII] A process for the treatment of molten ferrous metal in the presence of a flux includes the step of making additions of fluxing material during the treatment by feeding the powdered fluxing material through a flame into the molten metal or molten flux already present on the surface thereof. As shown, molten metal flowing from a cupola 14 through a lander 15 into a ladle 16 has a flame containiing a flux played on to it from a nozzle 17. In a modification, Fig. 1 (not shown) the flame may be directed against a stream of molten metal as it flows from one ladle to another. By making the flame oxidizing in character it may serve to oxidize impurities from the metal.

Patent GB-934663-A (GB)
Title: Dyeing of fabrics
IPC: C03C25/10
Filed: 1961-05-02
Abstract: A process for dyeing fabrics having relatively tight and loosely constructed surface areas to obtain different tone effects involves the application of a dispersion of anionically charged pigment particles which contains an organic cationic flocculating agent of the type of deacetylated chitin (preferred); polyakylpolyamines; polyalkyl-polyamine fatty acid reaction products; amino aldehyde condensate dye fixatives; methyl chloride quaternary ammonium salt of the stearic acid amide of 1-(2-aminoethyl)-2-heptadecenyl-2-imidazoline; fluid oil-inwater type emulsions of low molecular weight polyethylene chemically stabilized with a cationic amine acetate derivative of a long chain fatty compound; dicyandiamide formaldehyde dye fixatives; colloidal cationic thermosetting resinous reaction products of straight chain poly-functional amines and an aldehyde; or a mixture of such agents, in an amount to effect flocculation of at least a portion of the anionically charged pigment at a pH of 5-10,5 along with a resin binder and heating the so treated fabric to fix the pigment on the loosely constructed areas. The dyebaths may also contain non-slip and delustering agents, e.g. when dyeing glass fibres, colloidal silica and abrasion resistance agents, e.g. polytetrafluorethylene as well as non-agglomerated pigment particles which will colour the tightly constructed surface areas to produce, if desired, multi-colour effects.  Glass fibres may also be given a water-repellant treatment with stearatochromyl chloride or other Werner complex in which the acid groups coordinated with the chromium atom has more than 10 carbon atoms.  The fabric may be made from any cellulosic fibre, wool, silk, acrylic, aromatic polyester, polyamide, polyvinyl, polyvinylidene, polyethylene, polypropylene and especially glass fibres particularly of lime-alumina-borosilicate or blends of any of the above.  Suitable fabrics are woven from textured, rubbed, loop, knot, slub, bulked, boucl<\>ae, taslan or filament-type yarns to produce loosely and tightly woven areas or have napped or flocked areas.  The pigments used may be inorganic, chiefly the oxides, sulphites and sulphates of Co, Cr, Al, Fe, Zn, Cd, Mn and Se and organic pigments of the phthalolyanine, anthraquinone, thioindizoid, indanthrene vat and azo coupling series, Hansa yellow and carbon black.  A number of resin binders are specified. The preferred medium is water but methanol, ethanol, isopropanol and acetone may also be used.  Curing may be effected at 200 DEG -400 DEG F.  Examples of dyeing glass fibre and spun rayon fabrics are given.
