Title: Improvements in and relating to fuel burners
IPC: F23D11/00
Filed: 1954-05-25
Abstract: 800,621. Burners. MILNE, O., and PEABODY, Ltd. May 25, 1955 [May 25, 1954], No. 15408/54. Class 75(1) [Also in Group XII] In a liquid fuel burner combustion air mixes with fuel from the tip 21 in the throat after passing through an annular channel 30 in the throat masonry. The throat comprises refractory segmental tiles 26 lining an opening 25 in the furnace wall 13, the annular channel being divided by the rim 32 of a cup-shaped member 31 attached to the burner tube 22. The space between the burner mounting wall 16 and the wall 13 forms a plenum chamber, air passing therefrom to the channel 30 through a resgister 14 having adjustable air-whirling doors 20. The tiles have ribs and a radial wall 29 such that a thorough mixing of the fuel-air mixture ensues in the throat Each tile may have a wall dividing its channel so that a continuous channel 30 is not formed. In a throat comprising tiles each having a dividing wall 36, Fig. 5, the wall opening 25 forms the outer surface of a non-continuous channel 30, whilst the tiles form the inner and rearward throat surfaces. In divided channel throat constructions the cup wall 32, Fig. 6, is slotted to provide tongues to fit against the side faces and forward ends of the dividing walls. Such walls may be radial to the throat axis or helical so that the air will rotate about said axis in the divided parts of the channel 30 and discharge into the cup 31 in helical streams. Instead of tiles, the throat may be formed from a refractory material as a single integral unit. Specification 701,354 is referred to.

Abstract: 636,531. Tanks. SELF-PRIMING PUMP & ENGINEERING CO., Ltd., MEREDEW, G. C., and HIGGINS, D. G. May 21, 1946, No. 15412. [Class 69 (i)] [Also in Group XXVII] In an aircraft fuel system a sleeve 3, guided by rollers 4 on pillars 5, is connected by levers 8, pivoted at 9, to an annular weight 6 fitted with rollers 7 sliding on the casing 2 of a pump unit preferably of the type described in Speci. fication 558,040, [Group XXVI], immersed in the fuel tank and constituting the outlet therefrom. Under normal flight conditions the weight 6 rests on springs 15 and keeps the sleeve 3 raised so that the pump draws fuel under the bottom of the sleeve, but when negative " g " raises the weight 6, the levers 8 force the sleeve 3 down to make sealing engagement with a resilient ring 22 and the pump draws its fuel from the level of the top of the sleeve. The whole unit may be fitted within a sub-section of the fuel tank, flap-valves in the top of the section preventing fuel flowing out of it under negative " g " conditions. In a modification, the sleeve 3 is fixed and a movable ring connected thereto by a flexible bellows is actuated by the weight 6 through racks and pinions to close the fuel entry at the bottom of the sleeve under negative " g " conditions.

Abstract: 312,180. Kutter, L. May 18, 1928, [Convention date]. Self - filling, nib-retracting, reservoir pens; penwipers.-In a fountain pen, a tubular member 21 carrying the nib 9, feedbar 28, and reservoir 8 is slidable in a second tubular member 2') provided with a closure flap 27 for the aperture for the nib, the movement of the members 20, 21 being guided and limited by a pin and groove inaccessible from outside. The arrangement is such that filling can be effected when the nib has been projected to writing-position. The member 21 encloses a sleeve or sheet metal tube 25, having an apertured rear end in which is slidable a plug 10 connected to a spring 22 adapted to be buckled for causing deflation of the reservoir 8 for self-filling purposes. The inner end of the spring 22 is provided with a flanged head 23 engaging a slot 24 in the tube 25, the slot tapering towards the nib end of the pen so that the head 23 is prevented from disengagement. The head 23 enters a groove in the tubular member 20 to limit the telescoping movement of the members 20, 21. The closure 27 is acted on by a spring tending to keep it closed, but is opened by the nib when the nib is moved to writing- position, damage to the nib being prevented by covering the inner face with soft material which serves also as a penwiper. A pocket-clip 30 is provided,

Abstract: <PICT:0945735/C3/1> Semi-conductor materials are etched selectively by coating with a photo-sensitive masking material which is then exposed to light through a stencil of the desired pattern, which is then developed removing areas of masking material, this is then etched mounting a positive electrode 23 in parallel alignment with the prepared surface of the semi-conductor 10 as shown in Fig. 5.  By this means "under-cutting" at the edges of the mask is prevented, and the edges of the etched area are sharp.  Preferably a germanium material is etched with 20% H3PO4 solution, and silicon with 20 to 40% H2SO4 containing a little ammonium bifluoride.  Before the etching step the coated material may be washed and baked at 150  DEG C. to harden the patterned coating.  The transistor produced has highly defined etch detail and may be used in the miniature net-works described in Specification 945,734.
