Title: Disc-type aircraft
Inventor: FROST JOHN CARVER MEADOWS
IPC: B64C39/00
Filed: 1955-07-05
Abstract: 893,330. Aircraft. AVRO AIRCRAFT Ltd. July 4, 1956 [July 5, 1955], No. 19459/55. Class 4. [Also in Group XXVI] In an aircraft having a lentiform structure, air is compressed and supplied to ram-jet engines, each located in a radial duct. Air is forced into a plenum chamber 40 by an axialflow compresser 34 driven by an axial-flow turbine 36 with gas collected in a trough 38 after exhaust from three gas turbine engines 26 arranged radially with respect to the aircraft. Air from this chamber 40 is supplied to the gas turbine engines 26 and to ram-jet engines 61, one hundred and forty-four of which are mounted in radial ducts 13 formed by alternate long and short ribs 10 and 12. When the aircraft achieves sufficient air speed, ram air is admitted by flaps 51 and when the pressure of this air exceeds that of the air in the chamber 40, doors 60 close and the ram-jet engines function only on the air forced through the flaps 51. The exhaust gases from the ram-jet engines are vented through seventy-two ports 73, 74 in the upper skin 18 and 144 ports 79, 80 in the lower skin 19 of the aircraft and through seventy-two upper and seventytwo lower rectangular nozzles 91, 92. These ports and nozzles are fitted with louvres to direct the gases and are controlled by moving shutters. For take-off, shutters 75, 76 close the upper ports 73, 74 and lower shutters 81, 82 only open ports 79, 80 having louvres directing the gases downwardly. When the aircraft has risen vertically with the " ground cushion effect " the pilot can assume forward flight by a control which can move gradually to open upper ports 73, 74, to close downwardly ports 79, 80 and to open ports 79, 80 which direct gases rearwardly. During this procedure the aircraft is normally manoeuvred by flow of cold gas from the compresser 34 but for rapid take-off or for a heavily-loaded aircraft the pilot may light the ram-jet engines. Further shutters over port and starboard upper and lower ports give directional control. Flight control is effected by manipulation of a stick 104 linked to the shutters 95, Fig. 5, these being grouped so that six adjacent shutters rotate toegther. A universal mounting having limited movement enables the gyroscopic forces of the large compresser 34 to effect automatic stability through three links 107 connecting the stator ring of the compresser to the control stick 104. In a modification, Fig. 9, four gas turbine engines 200 are employed, with inlets 203 facing outboardly and their exhaust gases driving a radial flow turbine 208 and hence an inward radial flow compresser 202. With this aircraft, all air for the ram-jet engines flows through this compresser. The control is similar, but four arms 226 transmit gyroscopic forces to the control stick. A third arrangement, Fig. 13, includes upward-flow vertical gas turbine engines 300, their exhaust gases driving a turbine 308 and hence a compresser 310. Specification 898,360 is referred to.

Filed: 1926-08-11
Abstract: 279,959. Capon, R. S. Aug. 11, 1926. Races, recording-apparatus for. - An apparatus for ascertaining the speed of an object over a predetermined course comprises a single camera for a lapping course or two cameras where the starting and finishing lines are separate, a film in each camera adapted to be moved across a slot at a uniform speed such that each part is exposed for a suitable exposure period, and means for marking the film at suitable time intervals so that the instant of passing the starting and finishing lines mav be read off. In the form shown the camera o, Fig. 1 has a lens 1, a mask or stop 3 with a vertical slot 4 in front of the focal plane 2, and a film strin 5 in the said plane mounted on spools 7, 8. The strip 5 can be drawn across the slot 4 in one direction or the other by clockwork or other means, the speed being so related to the width of slot and aperture of lens that the time of passing of a point of the film is equal to the normal exposure time of the film. The time graduations on the film may be produced by arranging a spark gap 10 at the lower end of the slot, a spark being sent across the gap every second by clockwork adapted to make and break the primary circuit of a transformer. When two cameras are employed the primary windings 12 of the transformers are connected by a make-andbreak switch 13, Fig. 2, and a master switch 14 at each end may be inserted in series with the primary windings. The master switches may serve to control the driving mechanism for the films one starting and the other stopping both films. The shutters may also be controlled simultaneously with the starting and stopping of the films. Double pole switches are shown, one arm 15 being in series with the primary winding for controlling the spark and the other arm 16 in an independent circuit controlling the film driving and shutter operating circuits 17.

Title: Improvements in box covering machines
IPC: B31B13/34
Filed: 1923-08-10
Abstract: 203,314. Worcester, A. Sept. 1, 1922, [Convention date]. Machines for covering boxes. In a boxcovering machine of the type in which a box body is continuously rotated whilst the cover strip is applied to it the cutter for severing the strip is operated through trip gear so that it can be actuated either by power or manually. The movement of the cutter carrier 13 is taken from a cam 34 with which a push rod 31 engages, the rod 31 actuating a lever 25 which rotates loosely about a shaft 23. In moving from the position shown in Fig. 4 to that shown in Fig. 6, an arm 43 carried by the lever 25 engages a finger piece 28 keyed to the shaft 23, thereby raising the cutter 10 until a pawl 40 also carried by the lever 25 engages a bracket 41 on the bed 4 of the machine and lifts the arm 43 clear of the finger piece 28. During the continued movement of the lever 25 the cutter 10, which is now freed from the power mechanism, is raised to its extreme position by a counterweight 46. The lever 25 on its return stroke engages an overhanging portion of the finger 28 and operates through the medium of levers 21, 19 to lower the cutter 10. The shape of the cam 34 allows the cutter to be accelerated at the end of its downward stroke and since the return movement of the rod 31 is due only to the spring 36 any obstruction between the cutter and the base plates 5 stops the cutter. The former on which the box is rotated is mounted upon an arm which has provision for angular and longitudinal movement relative to the bed 4 of the machine. A three-step pulley belt drive is provided for adjustment of the speed of the cam and former and the position of the cutting blade 10 relative to the base plate 5 can be adjusted by set-screws 15.
