Title: Improvements in or relating to aircraft drift sights
IPC: G01C21/20
Filed: 1945-09-03
Abstract: 598,419. Drift sights ; optical systems. WILSON, E., and LEE, R. W. Sept. 3, 1945, No. 22600. [Classes 97 (i) and 97 (ii)] The drift angle P, Figs. 1 and 3, of an aircraft is measured by following, by means of a sighting element 10, the path KX along which a ground object appears to move in the observing plane HJKL, and determining the point X at which the path KX intersects the horizon line HJ. The element 10 consists of the follower element of a pantograph and moves radially of, and rotationally around, a point C<1>, Fig. 3, preferably corresponding in the projecting plane HJKL to the point C vertically below the aircraft. As shown in Fig. 6, the image of the ground is transmitted by prism 12 and optical system 13 to an observing plane viewed by the eye-piece 14. The sighting element 10 is the optical image of an originating member 10x and is introduced into the observing plane by an optical pantograph 18-22. The pivot point 27 of the member 10x may be adjusted along rails 29, also pivoted at 31, to represent the point of impact on the ground of a dropped object of known trail angle. This adjustment is effected by a screw device according to the trail angle and angular adjustment of the rails is effected through a coupling (not shown in Fig. 6) by the rotation of the prism or mirror 20. The prisms 20 and 12 are linked so as to turn simultaneously, the prism 20 being adjusted to such an angle as will keep the sighting element pointing along the path of the object it is made to follow. The corresponding turning of the prism 12 displaces the observing field to one side or the other to increase the range of the instrument. The mirror 18 has two positions. In one, the sighting member 10x is blocked out and a rotatable, parallel-line graticule 23 is substituted. In taking vertical sights, the prism 12 is tilted to the appropriate angle and the graticule is superimposed on the ground image and is turned until parallel with paths of objects thereon. The apparatus is housed in a casing having an eye-piece at the top. The casing is secured to the aircraft by a shock-absorbing mounting with the sighting prism assembly projecting through the skin of the aircraft.

Filed: 1937-08-18
Abstract: 505,971. Roasting coffee &c. JALMA, M. M., and COUTINHO, H. Aug. 18, 1937, No. 22692. [Class 58] [Also in Group VI] Gases given off from the roasting of vegetable materials, e.g. coffee, cocoa beans, peanuts, cereals, and nuts, which gases contain organic compounds of high molecular weight and no substantial quantity of oxygen, are purified by heating to a high temperature to crack the organic compounds to compounds of a lower molecular weight, adding oxygen to the cracked gases, and then oxidizing the organic compounds in the gases. The invention is particularly described with reference to the treatment of the gases obtained on roasting coffee beans at 300-425‹ C. The roasting gases, may be in admixture with fuel gases, pass through a chaff separator, and then to a cracking chamber at 400‹ C. or above and containing refractory material such as kaolin, clay, pumice, kieselguhr, crushed brick, &c. which may be coated and/or impregnated with ,cracking catalysts and, if desired, reducing catalysts. The gases, mixed with preferably preheated oxygen are then passed through a chamber at, say, 300-400‹ C. and containing an oxidation catalyst, e.g. copper oxide, sulplate or chloride, or pumice coated and/or impregnated with finely divided platinum, zinc oxide, magnesium oxide, &c. The purification unit preferably comprises two concentric cylinders, the annular space so formed containing refractory material, and the inner cylinder the oxidation catalyst. The means for heating the inner and outer cylinders are independent. Oxygen or oxygen-containing gas is supplied to the inner cylinder through a pipe heated by radiation from the outer cylinder. A single purification unit may be used in combination with a number of coffee roasting chambers. The purified gases may be scrubbed to remove water and carbon dioxide, and may be returned wholly or in part to the roasting chamber.
