Title: Improvements in or relating to screens for the air intakes of aircraft engines
IPC: F02C7/055
Filed: 1959-04-27
Abstract: 853,646. Gas-turbine plant. WESTING- HOUSE ELECTRIC CORPORATION. April 27, 1959 [April 29, 1958], No. 14223/59. Class 110 (3). A debris guard 27 at the annular air intake opening of an aircraft gas-turbine engine is formed of a readily deformable or flexible foraminous material, such as woven wire mesh, preferably supported by ribs 29, and is pivotally supported on the inner cylindrical wall 16 of the air intake passage by means of hinges 30. In the extended position shown, the guard 27 is of substantially frusto-conical shape so that intercepted debris is funnelled inwardly into a debris trap 32, thereby avoiding clogging of the wire mesh. The debris remains in the trap 32 until it is removed during routine engine inspection or servicing. To bring the debris guard 27 into its inoperative position clear of the air intake passage, the debris trap 32 is moved rearwardly by means of an actuator 39 and acts through links 36 to pivot the ribs 29 about the hinges 30 so that the guard 27 is closed to substantially cylindrical shape. A hollow fairing 21 is then moved rearwardly into abutment with the wall 16 by means of an actuator 24, thereby enclosing the debris guard 27.

Abstract: 937,800. Hop-picking machines. AGROSTROJ PROSTEJOV, NARODNI PODNIK. April 13, 1962, No. 14456/62. Class 6(3). A hop-picking machine comprises two vertically-spaced endless conveyers 3, 7, the upper conveyer being equipped with hooks anc the lower conveyer being equipped with transversely-extending abutments 9 over which the bines 5 are gradually drawn, as they are stripped, by the upper conveyer, which travels in the same direction but more rapidly, there being a picking mechanism disposed below the two conveyers and comprising two sets oj picking members 12, 13, the lower set being offset relatively to the upper. The bines are attached to the hooks so that they dangle through the picking members, being gradually drawn into a horizontal position by the differential speed of the two conveyers. The upper conveyer travels through a closed path and is provided with pendant guiding members 10 which assist in maintaining the bines horizontal during the later portions of their path. The stripped bines are discharged at 17, Fig. 3, and the hops fall on to an inclined conveyer 2. The abutments 9 comprise rodlike members projecting horizontally from the conveyer 7, the outer ends of the abutments being supported along the straight portions of their paths. The spacing of the hooks on the upper conveyer is in the same relation to that of the abutments on the lower conveyer as the ratio of their relative speeds.

Abstract: 563,046. Gaseous fuels. STEIN SCHLAEGER, M. Oct. 23, 1942, No. 14932. [Class 55 (ii)] In the production of gaseous fuels of high calorific value and especially those containing methane, ethane and propane, producer gas is burnt and at least a part.of the sensible heat of the combustion products is used to heat a regenerator which is then used to superheat steam or gases, the sensible heat of which is used for the cracking of oils, tars or hydrocarbon gases to produce the gaseous fuels. When only a part of the sensible heat of the combustion products is used to heat the regenerator, the remainder is employed for the cracking of the oils &c. The gases used for heating the regenerator may subsequently be used for cracking oils. The gaseous fuels may be used in an internal-combustion engine or gas turbine, and the exhaust used to preheat gases or superheat steam for the production of further gaseous fuels.
