IPC: F23C99/00
Filed: 1925-01-19
Abstract: 228,161. Grillet, L. Jan. 21, 1924, [Convention date]. Spray burners; liquid fuel supply.-In a liquid fuel burner apparatus, a mixture of fuel and air formed in a chamber 12 is conveyed by a pipe 18 to a pulverizing device 19 consisting of a chamber 22 which is formed with a plane surface opposite, the end of the pipe and contains a fixed or rotatable member 24 having a helically grooved outer surface. The member 24 consists of two truncated cones connected at their small bases, and may be formed with lateral projections or mounted on ball bearings to retain it in position in the chamber 22. The atomized fuel issues from an orifice 23 in the chamber 22 at such a velocity that combustion commences at a distance. of from 5 to 8 cm. from the orifice. The device 19 is carried by a support 26 which is secured by a screw 27 to the burner nozzle 25. The secondary air supply is regulated by means of an adjustable deflector 28. The liquid fuel is supplied to the chamber 12 from a reservoir 1 which is maintained under pressure by an electrically driven compressor 6, the fuel being heated by passage through a coil 14 arranged in the compressor casing. The compressed air in the reservoir 1 issues through an adjustable safety valve 8 to an expansion chamber 10 from which it passes to the chamber 12. The fuel and air supply pipes 15, 11 are fitted with control cocks 16, 17 respectively. The cocks 16, 17 may be thermostatically operated. The Specification as open to inspection under Sect. 91 (3) (a) states that the member 24 may be of cylindrical form. This subject-matter does not appear in the Specification as accepted.

Filed: 1945-01-19
Abstract: 591,637. Aerials. ROSS, W. :Jan: 19, 1945, No. 1622. Drawings to Specification.` [Class 40 (v)] In order to avoid polarization and other errors the Adcock aerials of a radio direction finder. have their horizontal feeders protected by a flat horizontal conductive screen spaced above the ground occupied by and surrounding, the system, and means are provided at -the perimeter of the screen to. avoid the effects; of standing waves. Preferably the screen, 11 consists of wire mesh with good; electrical connections at all intersections and is circular in shape and supported on posts. If of the order of five wavelengths in diameter it is, not essential that it should be earthed, but .;to . avoid standing waves on screens of practical size it is necessary to provide either effective, earth connections round the outside, and preferably also at Àother points, or radial conductors extending outwards from the periphery a few degrees apart. The latter arrangement is particularly suitable where the ground conductivity is fairly low. The radial conductors are most effective when an odd number of quarter wavelengths long and, to provide good conditions over a wide waveband, may be arranged in groups of several different lengths. The horizontal aerial connections may be the central conductors of concentric cables laid over the surface of the screen and having the outer conductors bonded thereto.

[Class 115.] Luffing davits 4 are pivoted at 5 to a deck standard 2 to which the chocks 15 also pivoted at 13 to the davit are connected by a link 8 the connection between the chock and the link permitting some lost motion. The boat falls 24 are passed over pulleys 23 at the davit head and pulleys 25, 26 to the winch which is of usual construction. In operation the release of a counterbalanced locking-dog 28 and of the winch brake allows the davits to luff under gravity the chock at the same time falling away from beneath the supported boat 19. In the extreme outboard position, the chock acts as a stay for the davit. In a modification, a single davit is employed for handling a boat and comprises a standard with T-head to the ends of which the falls are led..

The apparatus has a mounting plate 15 supported by springs 14 on a base-plate 10 having elastomeric feet 11. At one end the plate is connected by elastomeric buttons 21 and bolts 22 to a curved bar 20 extending above an electromagnet 23, 24 secured to the plate 15. The other end of the bar is connected by a bolt 33 and elastomeric grommet 34 to a compression spring 30 and an adjustable tension spring 31, in turn, connected to the plate 15. The end of the plate is also secured by the bolt 33 to an arm 40a of a support 40 for the container 50, the support also being connected by a bracket 41 and elastomeric insulator 43 to an end of the plate 15. The container 50 has a cover 51 and is of moulded vinyl having a substantially horizontal cylindrical shape with flat end walls 52. The outer surface of the container has a protective clip 54 formed with an ear 55 engageable by a latch 45. A moulded housing 60 encloses the apparatus and has an opening 61 for the container. The electromagnet is energized through a switch and half-wave rectifying diode and rheostat so as to be intermittently energized to rock the bar 20 about an axis A so that an axis B has a resultant reciprocatory movement in the direction of arrow R to impart such movement to one side of the container. The other side of the container has an axis F which is restrained by the bracket 41 to reciprocate in the horizontal direction L. The theoretical centre CO of a portion (below the line EE) of the path of the mass of material and abrasive  medium, which may be wet or dry, is above and to one side of the centre of gravity CG of the mass so that compaction occurs below a line EE and separation occurs above the line.
