Filed: 1920-04-29
Abstract: 142,489. Ritchie & Co., W. C., (Assignees of Milmoe, M. J.). Jan. 9, 1915, [Convention date]. Sheet-separators; pile supports.-In a. machine for making paper covered boxes, a rectangular box blank with cut-away corners is fed from the bottom of a magazine 48, Fig. 6, by means of a pair of horizontally-reciprocating bars 85 with shouldered front ends 88 provided with downwardly-inclined guiding-fingers 87. The bars 85 advance about half way under the magazine, recede slightly, and then advance fully, thus enabling them to take hold of the blank again if they lose their hold during the first advance. After dropping from the fingers 87, the blank slides down guides until it rests in a vertical position upon a stop 144, this downward movement being assisted, if necessary, by a pair of swinging fingers 150. Upon movement to the right of a pusher 122, the stop 144 is withdrawn and the blank falls squarely in front of the pusher. A previously glued covering-strip 37, Fig. 13, is fed to the machine by a slide 247 carrying a spring-pressed arm 253, which holds the paper down, and a pair of spring-pressed dogs 254 arranged to prevent retraction of the paper strip. The paper, which projects beyond the sides of the box, is cut by shears 257, 258.

Abstract: 1417041 Coated alumina and silica particles RICOH KK and MIZUSAWA KAGAKU KOGYO KK 13 March 1973 [14 March 1972] 12017/73 Heading C1A [Also in Division G2] Particles of alumina or silica or a mixture thereof having a diameter between 0À1 and 2 mm. and a mean pore radius between 25 and 300 Š are impregnated with a non-volatile amine or basic, nitrogen-containing heterocyclic compound, e.g. morpholine, are used as photographic developers (see Division G2). The particles may be produced, e.g. by mixing sodium silicate with a basic aluminium sulphate sol of molar ratio of SO 3  to Al 2 O 3  between 0À8 and 1À6 and adding 40% sulphuric acid and water. The resulting liquid is sprayed into a column having a layer of spindle oil floating on water at 85‹ C. to produce a hydrogel of diameter 0À3-6 mm. The hydrogel was washed, treated with ammonia or caustic soda and washed again to remove sulphate ions and dried to give particles of diameter 0À1 to 2 mm. and a mean pore radius of 53 Š. Sodium silicate may be omitted to produce alumina particles. Alternatively commercial aluminium hydroxide may be mixed with an acid clay and water and the mixture moulded through a 0À7 mm. diameter nozzle. The mouldings were shaped into spheres, dried and calcined to give a gel of diameter 0À5-2 mm. and mean pore radius of 45 Š. In this embodiment the aluminium hydroxide may be admixed with the alumina/silica hydrogel made as above before kneading. The particles may be coated with an alkali metal or alkaline earth metal oxide (e.g. Na 2 O, MgO or CaO), especially if not subjected to alkaline treatment, before impregnation. Specified amines are mono-, di-, and tri-ethanolamine, hexyl- or benzyl-amine and cyclohexyl- and cyclobutyl-amine.

Title: Improvements in liquid fuel supply systems for gas turbine engines
IPC: F02C7/22
Filed: 1953-05-05
Abstract: 750,909. Gas turbine plant. DOWTY FUEL SYSTEMS, Ltd., and CAREY, F. H. June 23, 1954 [May 5, 1953], No. 12504/53. Class 110(3) '[Also in Group XXVIII] The invention relates to a gas turbine fuel system in which an engine-driven fuel pump 15 draws fuel through a feed line 17 from a tank 18 and delivers it through a delivery line 13 to spill type burners 11, the spill from which is returned to the' feed line 17 through a servo-operated valve 21. According to the invention, a non-return valve 29 is arranged in the feed line 17, an auxiliary engine-driven pump 22 of less delivery rate under normal engine conditions than the pump 15 is arranged to draw fuel from the feed line before the non-return valve and return it to the feed line after the non- return valve through a delivery conduit 27, a branch conduit 30 is arranged to connect the delivery conduit 27 to the delivery line 13 and a change-over valve 32, biased to assume a normal position in which the conduit 27 is connected to the feed line 17 and the connection to the conduit 30 shut off is arranged at the junction of the conduits 27, 30. The arrangement is such that in normal operation, the entire output of the pump 22 passes through the pump 15 together with some make up from the tank 18. The pressure at the discharge of the pump 22 is therefore low. If the pump 15 fails, the pressure in the conduit 27 will rise and cause the valve 32 to move against the action of spring 35 and connect the conduits 27, 30 and thus maintain the fuel supply. The valve 32 at the same time shuts off the connection between the conduits 27 and feed line 17. A filter 36 may be arranged in the feed line 17 and a check valve in conduit 30. The pumps 15, 22 are of the positive displacement type.
