Title: Improvements in and relating to aircraft with rotary-wings
IPC: B64C27/54
Filed: 1946-07-30
Abstract: 615,156. Swash-plate mechanism. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and WATSON, K. July 30, 1946, No. 22640. [Class 80 (iii)] [Also in Group XXXIII] The invention relates to a mechanism of the type employing Z-cranks for inclining a swash plate or spider to vary cyclically the pitch of the rotor blades of a rotating wing aircraft. According to the invention the cyclic pitch control mechanism comprises a gimbal mounting for the non-rotary element of the swash plate 18 of which the inner and outer gimbal rings 14, 16 are respectively connected to one and the other of rings 22, 26 carried by two independently rotatable Z-cranks 22, 25 on coaxial sleeves 11, 12 by linkages (one of which-28, 29, 30-is shown in Fig. 4) such that the interlinked points of each ring and the corresponding gimbal ring are in a plane containing the rotor axis and perpendicular to the axis of the trunnions on which the gimbal ring is mounted. Thus on rotating the Z-cranks 22, 25 by means of cables passing over pulleys 36, 37 the inclination of the rings 23, 26, and consequently of the swash plate 18 is altered to alter the cyclical pitch change. In a modification of the construction shown a further coaxial sleeve encloses the sleeve 12 and has a Z-crank which carries a loose ring held against rotation and having a laterally extending arm restrained from axial move ment so that rotation of the third sleeve by a further operating pulley raises and lowers the third sleeve to raise and lower the swash plate 18.

Abstract: 1307565 Starting HUSQVARNA VAPENFABRIKS AB 11 May 1970 [12 May 1969 24 Nov 1969] 22706/70 Heading F1K In a method of starting an internal-combustion engine 1 by means of gas under high-pressure which is used in at least one of the engine cylinders 3 for driving the engine during starting, the gas pressure is reduced below that of the source and supplied at such reduced pressure to the cylinder at intervals when the piston in the cylinder is in the proximity of the top dead centre position between the compression and expansion stroke. When the valve 9 is opened gas flows to the chamber 7. The valve 8 is opened and gas then flows to the pressure reducing valve 11. A valve 12 situated in the conduit 6 is operated by cam or other member (not shown) driven by the engine and controls the supply of gas to the engine cylinder. In a modification the compressed gas passes to the engine combustion chamber through a passage in the piston. In another modification a spring is tensioned and stores energy expended manually in turning a handle. When a centre member has turned through approximately 90 degrees a latching tooth is moved out of engagement with a toothed sector and a further member is rotated by the spring and an operating movement is transmitted to the valve causing the same to open.

Title: Improvements in accelerometer and inclinometer apparatus for investigating the motion of road vehicles
IPC: G01P15/03
Filed: 1927-09-01
Abstract: 301,774. Girling, A. H. G. Sept. 1, 1927. Accelerometers and retardometers. - An instrument for indicating acceleration and retardation forces affecting the speed of vehicles, and also for indicating the slope of a gradient comprises a movable mass free to travel along a straight track arranged with its axis in a vertical plane parallel to the line of motion of the vehicle and inclined to a horizontal line in that plane, the moving mass itself by its position or the character of its movement giving the indication. The inclined tube may be nearly filled with liquid, the indication being given by the air within. Fig. 1 shows a tube A mounted at a fixed angle in which a ball B is adapted to move up the incline if the percentage value of the weight of the vehicle and its load constituting the retarding force is not less than the tangent of the angle " x‹ " multiplied by 100. A level L is provided to assist setting the instrument. The tube is sloped in the opposite direction to measure an acceleration force. In another form two continuous tracks are mounted at different angles to give two limits for the forces, or one track may be bent to two different angles. To avoid the mass retarding when it travels quickly to the end of the track, buffer means may be fitted at the ends. In the form shown in Figs. 6, 8 the track A is set at the required angle by a hand-wheel F through a reduction gearing I, J. Mounted upon the spindle G of the hand-wheel is an index drum H. Spring keys P engage a spiral groove on the inside of the drum so that the latter moves axially whilst rotating. The index figures are arranged spirally on the outside of the drum and appear at the window R in the casing E. In another form an index dial is made to face the driver and the tube is inclined through movement of a spiral gear by moving a pointer over the dial which gives the inclination. In a further modification the mass engages one arm of a pivoted bent lever, the other arm of which is formed as a pointer to indicate the position of the mass. The track or tracks may be mounted in a support adapted to fit the radiator caps of the vehicle or to incorporate a radiator thermometer and may be combined with a mascot. If the vehicle is stationary on a gradient and the tube be moved until the ball rests somewhere between the ends the reading will give the incline of the gradient.

Title: Improvements in or relating to herbal smoking mixtures
IPC: A24B15/16
Filed: 1949-09-05
Abstract: 676,646. Herbal smoking mixtures. ARNOLD, M. A. Sept. 5, 1950 [Sept. 5, 1949], No. 22972/49. Class 130. A herbal smoking mixture comprises the leaves of coltsfoot (Tussilago farfara), alone or with those of other herbs, which have been impregnated and/or fermented, together with shredded fruit peels if desired, in a liquid flavouring or other medium, shredded, and only partially dried out. In one method of manufacture, the leaves are gathered and preserved whole or in as large portions as possible, and treated, after a limited degree of drying, with a solution of any one or more of the following: -fruit juices (concentrated or natural), sugar preparations, potassium nitrate, acids, alkalies, glycerine, an adhesive mucilage, colouring materials, flavourings such as liquorice and coumarin, and pulverised materials affecting the taste of the ultimate smoke. The leaves, together with the fruit peels if used, are laid in layers in tanks and each layer treated, the resultant mass being then compressed to produce a coherent block which is cut up into strips of suitable width which may, if desired, be rubbed out. Controlled drying is then effected as in a convection oven or by infrared lamps, so as to leave the resultant product slightly damp. Instead of treating the leaves and peel as they are being stacked, the liquid medium may be sprayed thereon whilst they are agitated in a vessel. Compression of the treated leaves and peel may be omitted in either case.

Title: Internal combustion engines
IPC: F01C1/063
Filed: 1935-08-16
Abstract: 466,199. Rotary internal combustion engines. JANSEN, O. Aug. 16, 1935, No. 23085. Void. Convention date, Sept. 7, 1934. [Class 110 (ii)] A rotary engine of the gearedvane type comprises a compression chamber 3, a storage chamber 27, a combustion chamber 2, and a working chamber 5. A casing 23 connects chambers 3, 5, which contain vanes alternatively fixed to the chamber walls, or fixed to a hollow rotating shaft 1. The chamber 5 is twice the length, and capacity, of the chamber 3, and the vanes in each have an alternating lead and lag of 22.5‹, or a total movement of 45‹ during a working stroke. A driven shaft 17 is coupled to the shaft 1 by elliptical gears 7<111>, 7<1111>, and to the casing 3 by elliptical gears 7<1>, 7<11>. Air from the atmosphere is drawn through slots 31 and compressed and delivered through further slots 32 into the storage chamber 27. Compressed air then passes a fuel nozzle 9 into a mixing chamber 25, the mixture passing through wire sieves 24, and burns and impinges on a disc 10 which distributes the gases radially. The fuel pipe 20, nozzle and disc rotate with an internal control shaft 11, 11<1>. The main supply of compressed air passes from the chamber 27 to the combustion chamber 2 through an annular disc valve 21. Compressed air passes by way of a pipe 22 to the fuel storage tank to force fuel up a pipe to the nozzle in the mixing chamber 25. Working fluid passes to the chamber 5 through slots 34, and is exhausted by way of further slots 35, beyond a partition 16 in the hollow shaft 11<1>. To control the size of slots 34 an axially slidable piston*13 can be moved through a rod 14 connected to an external hand lever through a spring. In the event of a sudden rise in pressure on the engine inlet side, the piston 13 may yield and compress its holding spring. The combustion chamber and working chamber are insulated against heat loss, but the compression chamber is air cooled. When heavy fuel is used, it is pre-heated by lamps or electrically. Heating coils 8 of the fuel supply pipe may be placed in the combustion chamber. The shaft 17 may be cranked to start the engine. The compression is adiabatic, and during the supply of heat in the combustion chamber, the pressure remains constant.
