Title: Improvements in aircraft
IPC: B64C27/625
Filed: 1944-06-23
Abstract: 580,231. Helicopters. DEHN, F. B. (Bell Aircraft Corporation)..June 23, 1944, No: 11988. [Class 4] The rotor 3 of a helicopter is pivoted on a mast 1 carried by the fuselage 2, and a rotating flywheel 4 is also mounted on the mast to which it is inclinable as shown so that in general the plane of the fly-wheel is maintained in its relation to the horizontal. The lift of the rotor 3 acts along the line OL at an inclination to the mast and being above the centre of gravity W will tend to pull the mast to a vertical position. If the fly-wheel is adjusted by. the pilot so that its plane is inclined to the horizontal the reactions between the rotor and fly-wheel tend to bring the rotor parallel to the fly-wheel so that forward flight, for example, may be obtained by giving a suitable forward inclination to the fly-wheel. As shown in Fig. 6, the fly-wheel 34 is universally jointed to a rotating shaft 44 inside the mast 31, on which is mounted in bearings a rotating sleeve 33 ; a shaft 46 of a motor in the fuselage drives the two rotating parts, a greater speed being given to the flywheel. The rotor blades 60, 61 are mounted in a ring 59 universally jointed to a boss 33a on the sleeve 33 as shown in horizontal section, Fig. 7. Control of the feathering of the blades is exerted by the fly-wheel 34 through a rod 68 pivoted at its upper end to a control plate 63 connected through bearings 62 to the flywheel, the lower end of the rod being pivoted to the ring 59. Inclination of the fly-wheel is accompanied by a similar inclination of the control plate 63 which produces an inclination of the ring 59 to determine the feathering of the rotor blades. The pilot's control of the flywheel is exerted through an arm 75 connected by a bearing to an inclinable plate 71 which is connected by three vertical rods 72 to the control plate 63. A plate 73 with slots'for receiving rods 68 and 72 is rigidly mounted on the upper end of rotating sleeve 33 and drives the control plate 63 and the plate 71 through the rods, the plates 63 and 71 being maintained parallel by rods 72. In a modified construction, a pair of weighted inertia bars is combined with the rotor blade system for purposes of control.

Title: Improvements in or relating to the art of drawing sheet glass
IPC: C03B15/18
Filed: 1922-04-28
Abstract: 199,881. Jackson, W. J. Mellersh-, (Libbey-Owens Sheet Glass Co.). April 28, 1922. Drawing.-Relates to a process of drawing sheet glass in which the lateral parts of the sheet are guided, on leaving the mass of glass, in such a manner as to maintain the edges in a predetermined direction, and consists in arranging for the sheet of glass itself to drive the width-maintaining mechanism. The device consists of a series of sliding grippers which continuously hold out the edges of the sheet and stretch it laterally during the forming period, and they also act as as a drag on the edge of the sheet. The glass sheet 3, Fig. 1, is drawn upwards from a receptacle and passes over a bending-roll 4, as described in Specification 114,977. Edge-forming rolls 5 are arranged at or near the source of each edge of the sheet, and above these are arranged water-cooled guides 9, 11 on which grippers 6, Fig. 5, are free to slide. The guides 9, 11 are pivoted on vertical shafts 16 carried by frames 17, and can be moved away from the sheet by handles 22. The frames are closed by springs to bring them against the sheet. In operation, the frames are closed on the sheet and press the grippers 6 against the sheet edges. The grippers are carried upwards by contact with the sheet and thus prevent it from becoming narrower during the period in which it is formed. The grippers slide over the upper parts of the guide and are returned to the lower ends by gravity. Gear wheels 32, Fig. 3, mounted close against the lower loops of the guides 9, 11 and driven from a shaft 43, engage the grippers and feed them into contact with the sheets. The frames 17 are mounted on sliding carriages 26, and they may also be tilted to enable the lateral tension on the sheet to be adjusted. In a modification, the grippers move up and down vertical guides which are arranged in pairs on each side of the sheet. The guides of each pair are alternately moved away from the sheet by cams for a sufficient time to allow the grippers, which have moved up the guide, to slide down to their initial position.

Title: A planographic printing process using greasy or fatty ink
IPC: G03F7/14
Filed: 1957-04-12
Abstract: 830,623. Planographic printing processes. AGFA A.G. April 12, 1957 [April 18, 1956], No. 12091/57. Class 98(2) Images are produced by. the silversalt diffusion process in an ink-repellent layer that is chemically inert with respect to ferricyanides and ferrocyanides and are treated with an aqueous solution of a ferricyanide in the presence of a soluble metal salt, the metal ion of which is capable of forming a water-insoluble ferrocyanide or ferricyanide, which solution may also contain a complex former to prevent immediate precipitation of the metal ferricyanide, and such treated images are inked up for planographic printing. In Example 1 a silver image as from a line or half-tone original so produced on an anodically treated aluminium plate which may have been dipped beforehand into an aqueous colloidal silver sulphide nuclei solution is introduced after rinsing into a solution containing potassium ferricyanide, cobaltous nitrate, citric acid and sodium citrate, to give the image a violet appearance due to entrained cobalt ferricyanide, and the plate is again rinsed, dried, treated with aqueous ethanolic stearylamine containing sodium carbonate as surface active agent, and after evaporation of the ethanol the plate is rubbed with greasy ink, the latter is dried with talcum and the ink cleared off image-free areas with 4% phosphoric acid, when the plate may be gummed for protection if not to be used immediately for printing. The other six examples are generally similar, differing chiefly by (2) producing the silver image on surfacesaponified acetyl cellulose foil; (3) and (4) using nickelous and uranyl nitrates respectively instead of the cobaltous nitrate of Example 1; (5) producing the silver image on a nuclei containing gelatine layer of a paper foil; (6) using oxalic anions instead of the citric Example 1; and (7) including barium sulphate in the gelatine layer of Example 5 and zinc sulphate instead of cobaltous nitrate. Other soluble ferricyanides and other metal salts for treating the silver image formed in the ink-repellent layer are described.

Filed: 1922-05-01
Abstract: 203,018. Wepplo, I. W. May 1, 1922. Boring-bar machines; boring-bars. - In a machine for reboring the cylinders of internalcombustion engines of the type comprising a frame bolted to the cylinder casting and having an automatic stop-feed, the frame is attached to the .cylinder adjacent the one being bored and the boring-bar overhangs into the latter. The frame 1 is bolted to the cylinder casting by straps 8 and carries an electric motor 20 driving the boring-bar 2 through gearing 13, 16. A pinion 25 on the bar drives, through a lay shaft 27, a pinion 29 loose on the feed-screw 30 which screws into the bar. A flange 37, secured to the feed-screw, carries a spring-pressed plunger 34 which normally engages one of a number of sockets in the pinion 29 so that the screw is driven slightly faster than the bar for feeding. On contact of a collar 50, secured to the bar, with the bearing 9, end movement of the bar is arrested and the screw is lifted out of engagement with the pinion 29, a helical spring preventing the latter from rising. To retract the bar, the plunger is kept out of engagement with the pinion by a finger-piece 33 and the feed-screw is rotated by a handle 36. A spring 39 produces an end thrust on the screw which is sufficient for feeding. The tools 4, 5 are adjustable and are carried by a head 3, which is provided with a shoulder on which fits accurately a gauge 60 for setting the tools. The gauge carries a plunger 62 against which the cutting edges of the tools are se@ and having a micrometer head 63 which reads the diameter cut by the tools directly in inches, sixteenths and thousandths, the latter indicating the amount to be removed by the tools.
