The liquid flow-path comprises a passage 33 connected to the nozzle and opening into a bore 32 connected to the recess 24, the flow-path being obturated, as shown, by a valve pin 34 fitted with one or two seals 36. The pin 34 is connected to an actuator plate 40 pressed downwards by a spring 43 fitted to a cover 41. The compressed-air flow-path comprises passage 12b and bore 37 which is connected with the space 23 when member 20 is pushed towards body 10, an opening 37a and a gap between an outside wall of the member 19 and an inside wall 20a of the member 20 providing the connection when a gasket 21 fixed to member 20 passes the opening 37a. A passage 44 from the nozzle allows compressedair to pass to an annular space 39a beneath plate 40 and thus to lift the plate against spring 43 and open the liquid flow passage to the nozzle. When member 20 abuts shoulder 10b of body 10 compressed-air pressure drops and valve pin 34 seals the liquid flow passage; the pressure of compressed-air remaining serving to clear the nozzle of liquid. Movable member 20 is moved away from body 10 and further air enters through flap 28, the dispenser being thus made ready for further use. In another embodiment the liquid flow control valve is actuated by compressed-air pressure on a flexibly-mounted plate. The movable member may be made as a solid piston which fits inside the fixed member.

Abstract: 1,114, 823. Generating combustion products under pressure. M. PIANKO. Oct.28, 1965 [Dec.23, 1964], No.45726/65. Heading F1L. A combustion chamber utilizing air under pressure as the combustion-supporting medium, is formed with a slot or slots having end portions thereof disposed in overlapping spaced relation, there being deflectors which co-operate with the overlapping portions of the slot or slots and formed so as to change the direction of air inflowing between the overlapping portions. Fins are disposed downstream of the deflectors and are formed to give a rotational movement to the flow of air. A direction-reversing region is thus created in the region of the position of the air issuing from the slot in which the speed of the air is locally zero thus serving to stabilize the flame at a plurality of zones. The combustion chamber shown in Fig. 1 is of tubular form and comprises an end dome 2 and cylindrical sections 3, 4, 5 which overlap to provide annular air inlets each of which is provided with a U-section deflector 7 so that air flowing exteriorly of the combustion chamber in the direction of the arrow f1 reverses in direction to enter the combustion chamber. The air-flow again reverses in direction within the combustion chamber to flow in the direction of the arrows f3, the planes of reversal indicated at 15 constituting flame stabilizing zones. Swirl vanes 8 are disposed in the air inlet passages as shown. The embodiment of Fig.3 is similar except that the combustion chamber is of annular form, annular scoops 7 of U-section being provided. In Fig.4 the air-inlet 6' is of helical form, a U-shaped deflector 7 also of helical form and swirl vanes 8 being associated with the inlet. The embodiment of Fig. 5, (not shown) is similar to Fig.4 but the combustion chamber is of annular form. In Fig.6 the combustion chamber is formed with longitudinal slots 16, the edges of the slots being spaced apart to form longitudinal air-inlet openings. V-section members are disposed in the openings the first limb 7a acting to deflect air and the second limb 8a acting to give a rotational movement to the inflowing air.

IPC: C04B35/48
Filed: 1962-12-06
Abstract: Zircon grain is prepared by blending 20-95 parts granular zircon (at least 80% of the particles being larger than 0.074 mm.), 5-80 parts milled zircon (at least 90% of the particles being smaller than 0.074 mm.), 0.3-5.0 parts binder, 0.3-5.0 parts bonding material, and sufficient water to impart workability, e.g. 4-10 parts (all parts by weight); forming into green aggregates, and firing.  Granular zircon may be ore or mineral sand, and may be used to give milled zircon by crushing. The binder may be a starch (e.g. corn or potato starch or a dextrin), gum (e.g. gum tragacanth, alginates, carraghenates or carboxymethyl cellulose) resin (e.g. polyvinyl alcohol, chloride or acetate, or ureaformaldehyde resin), wax (e.g. paraffin wax) or paste (e.g. wheat paste); and is lost in firing. The bonding material, which imparts cohesive strength may be fire clay, bentonite, lime, sodium silicate, fluorspar, sodium silicofluoride, or sodium or aluminium phosphates; and 0.15-1.0 parts remain after firing.  The green aggregates, being angular particles 3-6 mm. in size, are formed by (a) extruding through an opening and slicing, (b) tumbling the dry constituents in a rotating drum while spraying with water, then tumbling under vacuum; or (c) casting in cavities; and may be cut smaller before or after drying.  This material may be dried at 90-120 DEG C., e.g. by upward passage of air through a packed or agitated bed, until the water content is 0-2%; and then fired above 800 DEG C., e.g. at 1200 DEG  C., by passing through a tubular kiln, until no water remains.  The density of the grains may be from 2.4-3.7 g./c.c. Ceramic articles may be made by blending 10-75 parts of the zircon grain with 65-130 parts ceramic slip (containing 50-90 parts of 0.018-0.07 mm. zircon, 15-40 parts water and possibly 0-15 parts clay, 0.05-1.0 parts Na silicate), pouring into casts and leaving at 20-30 DEG  C. for e.g. 2 hours and firing in a muffle furnace at 1100-1700 DEG  C. for 12-72 hours.
