Title: Atomizing burner for liquid fuel
IPC: F23D11/10
Filed: 1948-01-23
Abstract: 654,303. Liquid-fuel burners. N A A M - LOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Jan. 23, 1948, No. 2094. Convention date, Jan. 24, 1947. [Class 75(i)] A liquid-fuel burner 1 axially slidable relatively to the circular mouth 3 of a furnace combustion chamber is automatically adjusted in position so that the spray cone 4<SP>1</SP> (the angle of which varies as the fuel supply rate is varied) is always tangential to the mouth 3 of the furnace combustion chamber; the movement is effected by a pressure determined by the rate of fuel supply. The arrangement ensures that all the combustion air passes through the spray. An increase in fuel pressure with an increase in burner load decreases the angle of spray to 4, Fig. 1, the burner nozzle being automatically drawn back to position 1 where the spray cone again makes contact with the edge of the combustion chamber mouth 3. The axial movement of the burner nozzle may be effected by the pressure variation in the spill return line of the fuel or by the supply pressure. Thus the fuel returning by pipe 6 acts on a piston 8, Fig. 2, connected to a rack 9 constrained by springs 10 to rotate a pinion 11 to which is secured a pin 17 whose free end operates in a helical groove 15 in a bush 12 fixed on the burner tube 1. Rotation of the burner tube 1 is prevented by a pin 16 secured to the air register and operating in an axial groove 14 in bush 12. A servomotor may be used to vary the burner position, and may be operated by the fuel supply pressure Figs. 4-6 (not shown), or by a Venturi pressure derived from the quantity flow of atomizing air or steam. The supply of combustion air through the air register may also be controlled by the same mechanism.

Title: Injectable oil compositions
IPC: A61K49/04
Filed: 1965-01-18
Abstract: Injectable non-aqueous oil compositions for intravenous, intra-arterial or intra-lymphatic administration comprise a sterile mixture of one or more metabolizable, optionally brominated, or iodinated natural or synthetic esters of C11 to C24 fatty acids, being liquid at 37 DEG C., with 0.5 to 5% by weight of the composition of at least one non-toxic surface active agent having a solubility in said ester of at least 0.5% by weight at 37 DEG C.  By non-toxic is meant that the toxicity (L.D. 50) of the surface active agent in the mouse is greater than 10 gms./kg. orally and 1 gm./kg. by intraperitoneal injection; such agents are usually non-ionic, and may be partial esters of fatty acids with sorbitan, or polyoxyethylene ethers thereof, or castor oil-polyoxyethylene ethers, e.g. "Span", "Tween" (registered Trade Marks), or Emulsov, respectively.  Preferred surface active agents are polyethylene glycol monopalmitate, cotton seed oil monoglyceride-tartaric acid ester, e.g. "Drewmulse" (registered Trade Mark), and mixtures thereof.  Oils used may be olive, peanut, poppy seed, cotton seed, walnut, wheat, cod-liver, chaulmoogra, or the products of the alcoholysis of such oils by lower alcohols, e.g. ethyl oleate, and their brominated or iodinated derivatives such as Ultra-Fluid Lipiodol.  The oils may themselves form the therapeutic agent of the compositions, e.g. for X-ray contrast or intravenous feeding purposes, or may be carriers for liposoluble drugs, such as camphor, antimitotic agents, or vitamins A, D, E, F, or K.  Examples are given for an X-ray contrast medium, a nutrient injectable composition, and a composition of a radio-active iodine labelled oil.

Title: Improvements in the preparation and reproduction of drawings
IPC: G03C5/10
Filed: 1942-02-19
Abstract: 556,144. Luminescent materials. KODAK, Ltd., COPPIN, F. W., and MURRAY, A. Feb. 19, 1942, No. 2206. [Class 39 (i)] To obtain reproduction of some of the details of a map, plan or drawing independently of the remainder of the map &c. two or more inks are used having different fluorescent material, which will fluoresce at differing wave bands when illuminated by the same fluoroactivating light. If it is desired to see these differences visually the inks may be coloured differently. When three inks are used they are coloured blue, magenta and green containing respectively, as fluorescent materials chrysene, chrysene plus 1 per cent naphthacene (as described in Specification 542,006) and zinc cadmium sulphide dispersed in gum arabic solution. The reproduction may be effected by excluding white light and using suitable filters with a fluoractivating light such as U.V. light; or a white light source may be used and only the U.V. used by exclusion with filters. If a fourth set of details are to be sorted out these may be drawn in black ink and photographed by infra-red rays. Suitable emulsions are used in all cases to obtain the copies ; types of filters are given for the different colours. Specification 544,132 also is referred to.
Patent GB-289517-A (GB)
Title: Improvements in or relating to the wings or supporting planes of aircraft
IPC: B64C9/22
Filed: 1927-01-25
Abstract: 289,517. Wood, R. M. Jan. 25, 1927. Steering, balancing, and regulating altitude. -A pilot plane 1 is freely pivoted in advance of a main plane 4, so that at small incidences it sets itself as in Fig. 4 in the air stream, adding little to the drag, while at large incidences it rises as in Fig. 3 against a stop 6 to form a slot, which tends to maintain steady air flow over the upper surface. The pilot plane may extend only along the tip of the wing, and the stop 6 may be linked to the aileron. As shown in Fig. 7, downward movement of the aileron 12 from its neutral position lowers the upward limit of the pilot plane in a small degree, while upward movement of the aileron raises the limit in a greater degree. The link control may act in the opposite sense, as shown in Fig. 5. The stop 6 may be linked as in Fig 9 to a freely pivoted rear-flap 20, the movement of which is limited by check-wires 24, 25 or by stops. The flap 20 may be linked to the pilot plane itself, as in Fig. 14, so that as the pilot plane rises the flap is depressed; a slot may thus be opened between the main plane and flap, or the slot may be open in all positions of the flap. Automatic control of the camber of the wing, as in Fig. 14, may be combined with lateral control by enabling the pilot to superimpose a differential movement on the flap 20 of the two wings. Wires 16, 17 Fig. 15, from differentially geared pulleys are connected to the two flaps in such manner that these can only move up or down together while the control column 44 is held stationary, but movement of the column 44 superimposes an upward movement on one flap and a downward movement on the other. The same effect may be obtained by a lever 52, Fig. 17, pivoted on the control column 54 and connected by links to the flaps 33, 34. A pilot plane may be mounted in advance of a symmetrical aerofoil, such as a rudder, in which case it is pivoted one fifth of its chord behind its leading edge and a stop is provided on each side.
