Title: Improvements relating to the treatment of flue dust
IPC: F23J3/02
Filed: 1935-11-09
Abstract: 443,948. Treating furnace flue dust. LAURIE, D. NORTHALL-, 41, Lyncroft Gardens, Kilburn, London. Nov. 9, 1935, No. 31086. [Class 51 (i)] In a process for treating the dust obtained from the combustion of coal in boiler and other furnaces in order to avoid stickiness in the dust and to prevent its adhering to surfaces over which it passes, such as the surfaces of heat exchange apparatus, a certain amount of dry lime or other alkali in a finely divided state is introduced into the dust and at the same time the amount of moisture in the flue gases carrying the dust is controlled within certain limits. The degree of humidity of the flue gases is maintained at between 1.5 and 2 grammes per cubic foot measured at N.T.P., by analyzing the gas at intervals and accordingly regulating the amount of water added to the coal immediately before it is fed on to the grate. Within these limits of humidity, the amount of finely divided lime required is about one-tenth of the weight of sulphur in the coal. The alkali is fed in measured quantities from a hopper a by means of an adjustable measuring slide b reciprocated by a crank f and falls into a chamber g from which it is blown into a pipe h opening into the top of the furnace k and mixes with the flue gases passing over a wall n and down the flue o containing heat-exchange apparatus p.

IPC: A21C15/00
Filed: 1925-12-10
Abstract: 264,981. Stephenson, J. E. Dec. 10, 1925. Lever-actuated pumps; stroke, varying; mountings; pipes.-In a machine for filling pies &c. with gravy &c., a pump of known kind is carried by a bracket b, slidable on a pillar A between abutments a, a', and descends -bodily without relative movement of the plunger until the pie crust is penetrated by the nozzle, the bodily descent then ceasing whilst the plunger continues to descend and ejects the gravy. This is effected by connecting the operating lever E, which is returned by a spring G, to the bracket b by a two part rod J, the parts being hinged together at j and retained as a substantially rigid whole by a leaf spring J<1>. When the bracket b abuts against the lower stop a<1>, the rod J' breaks at its joint j' and continued depression of the lever E depresses the plunger C<1>. In order to regulate the quantity delivered to the pie, the lever E moves between the bifurcations of a bracket W having holes w for the insertion of a pin to limit the motion of the lever E according to the quantity to be delivered.

Title: Improvements in or relating to devices for maintaining mechanical oscillations
IPC: G04C3/06
Filed: 1955-11-03
Abstract: 800,341 Reciprocating electric motors; electric motors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 3, 1955 [Nov. 6, 1954], No. 31479/55. Class 35. [Also in Group XVIII] The oscillations of a mechanical vibrator are maintained by a maintaining circuit including a transistor, a pick-up coil and a driving coil. In the first embodiment a balance unit 1, Fig. 1, is maintained in oscillation by a maintaining circuit comprising a pick-up coil 8, a class B amplifier transistor 9 and a driving coil 10. The coil 8 co-operates with a magnetic disc 5 and the coil 10 with a rod 6 of permeable material carried by the balance staff. The maintaining pulse from the coil 10 occurs slightly before the mid-position of the balance unit. A small auxiliary permanent magnet 15 is located between the limbs 13 of the coil 8 so that as the disc 5 approaches the mid-position it receives a braking impulse from the magnet 15 and as the disc 5 moves away from the mid-position it receives a driving impulse from the magnet 15. The combined effect of the coil 10 and the permanent magnet 15 is that the maintaining impulse imparted to the balance unit is substantially symmetrical about the mid-position. The polarity of the disc 5 may be such that the driving impulse imparted thereto from the coil 10 occurs just after the balance unit has passed the mid-position and in this case the polarity of the permanent magnet 15 is reversed. To the same effect the winding direction of the coils 8, 10 may be reversed and a permanent magnet may be disposed between the limbs 14 of the coil 10. The lower limb 13 and the upper limb 14 may be integral. In another embodiment, Fig. 5, the two coils 8, 10 have a common core 18 having an auxiliary permanent magnet 19. In another example, Fig. 6, two transistors 22, 23 are provided so that a double pulse is transmitted to the driving coil 10. The two transistors are connected (respectively) to coils 25, 26 which effect step-by-step rotation of a polarized disc 27. In another embodiment, Fig. 7, the coils 8, 10 have a common core 32 and the disc 5<SP>1</SP> is magnetized as shown in Fig. 8. In this case the balance amplitude is less than 180 degrees. The auxiliary magnet 15 may be replaced by a magnet 15<SP>1</SP>. In a further example, Fig. 15, the disc 5 co-operates with two pairs of coils 8, 10 and 8<SP>1</SP>, 10<SP>1</SP>. In this case if the disc 5 swings over 180 degrees disturbing impulses are introduced but these can be obviated by magnetizing disc 5 as shown in Fig. 10 with a gradually decreasing polar strength. In a final example the disc 5<SP>111</SP> is magnetized as shown in Fig. 14, one pick-up coil 8, Fig. 12, and two driving coils 10<SP>1</SP>, 10<SP>11</SP> being provided. The balance is impulsed in one direction of movement only. Specifications 746,465, 763,427 and 800,340 are referred to.

Filed: 1934-11-05
Abstract: 449,900. Spray-producers. AKT.-GES. BROWN, BOVERI, & CIE, Baden, Switzerland. Nov. 5, 1934, No. 31784. Convention date, Nov. 4, 1933. [Class 69 (iii)] [See also Group XI] A spray burner for liquid-fuel burning furnaces comprises at least two concentrically arranged atomizing nozzles, the discharges from which may be regulated in steps and the whirl imparting body of the inner nozzle acting as the control piston for regulating the discharge from the next larger nozzle. Fig. 2 shows one construction of burner in which the displacement of a piston 4 uncovers successively passages 2, 21 admitting the fuel tangentially to a cylindrical chamber 1 for discharge from a nozzle aperture 3. When all the passages leading to the chamber 1 have been uncovered an abutment 9 on the piston 4 engages a flange 35 on a spring-pressed block 10 in which the chamber 1 and nozzle aperture 3 are formed so that a further upward movement of the piston 4 raises the block 10 and uncovers successively bores 7, 7<1>, 7<11> leading to a nozzle aperture 5. The burner is preferably so dimensioned that the fuel entering through the first bore 7 is approximately the same as when all the passages 2, 2<1> leading to the chamber 1 are uncovered. Fig. 3 shows a modification in which a cylinder 15 containing the whirl chamber for the nozzle 3 is formed with a cylindrical extension 16 slidable in a skirt 24 to which fuel is admitted through a groove 19 in the control piston 20 to assist the pressure of a spring 17. When the piston 20 has been raised sufficiently for the groove 19 to be covered by the edge 21 of the casing an outlet passage 22 in the member 20 is uncovered. The piston is then raised by the fuel pressure in the space 23 to uncover the bores 7, 7<1> leading to the nozzle 5. In a further modification shown in Fig. 5, a metal bellows 26 is substituted for the parts 16, 24 and the fuel escapes from the bellows through holes 31, 32 in the piston 20 when a spring-loaded sleeve 29 engages an abutment 28.
