Title: Sighting and Aiming Device for use upon Cannon or other Pieces of Ordnance.
Inventor: LAZARTE ENRIQUE
IPC: F41G3/00
Filed: 1916-05-04
Abstract: 124,838. Lazarte, E. May 4, 1916. Sights and methods of sighting.-Relates to anti-aircraft gun sights of the kind in which range and angle of sight corrections are effected by means of a transparent plate in the field of sight having a series of range curves for different angles of sight plotted thereon, such plate being adjustable relatively to a fixed vertical line so that the points of intersection of the curves with the fixed line, form sighting-marks, and vary as the movable plate is adjusted by hand according to the angle of sight. According to the invention, the sighting- device is in the form of a camera obscura, and the adjustments are effected automatically as the gun is elevated. The casing 1 carries a lens 6 in an adjustable mounting 7, a fixed transparent plate 8, and a rotatably adjustable ground-glass or like image-receiving plate 11 arranged in the focal plane of the lens. The casing 1 is secured to the gun carriage 3 by bars or legs 2 straddling the gun barrel, one pair of legs 2 preferably being adjustable to maintain parallelism between the axis of the lens and that of the gun barrel. The image plate 11 and the fixed plate 8 are provided with sighting-marks, indicating corrected lines of sights for various ranges at different angles of site. For this purpose, a single radial line 10 is marked upon the plate 8 having its inner end coincident with the optical centre or lens axis. Upon the image-receiving plate 11 is drawn a series of curves 25 corresponding to various ranges, and determined by plotting, so that, the plate 11 being rotated according to the angle of site, the intersection of any of the range curves with the radial line 10 indicates the corrected line of sight for that range. The plate 11 is mounted in a holder 12 externally toothed and geared by a pinion 14, shaft 13, and bevel-gearing 17 to a stationary toothed sector 19 on the gun carriage, so that rotation of the plate 11 is effected automatically as the gun is elevated, the angle of elevation of the gun being indicated by a scale 21 on the fixed sector 19, over which a pointer 20 moves. The image may be viewed directly or by reflexion in a mirror 26. The mirror-holder 27 is pivoted to the casing 1 and held by adjustable connexions 28, a hood 29, and view-opening 30 being preferably provided. The range may be estimated from the size of the image on the plate 11. To facilitate night sighting, a series of differently-coloured spots 25 may be associated with the various sighting-curves 23.

Title: Method of decorating objects and decorated objects obtained by means of these methods
IPC: B44F1/14
Filed: 1933-03-04
Abstract: 416,350. Embossing processes; embossing-surfaces. DUFAY, L., 123, Grande Rue, Besancon, Doubs, France. March 4, 1933, No. 6612. Convention date, March 31, 1932. [Class 100 (ii).] Iridescent and stereoscopic effects are produced by means of an embossing-member, such as a celluloid sheet 1, Figs. 1 and 2, having a grid-like surface comprising a series of straight, curved, or zig-zag grooves formed by sharp ridges 2 and polished faces 4, 5; the member being placed on the object to be decorated, such as a sheet of cardboard 7, Fig. 6, and pressure being applied locally mechanically or by means of a pointed burnisher to form complementary grooves 14 in part of the sheet, such as a triangle 10, after which the member 1 is rotated relatively to the sheet 7 and pressure is applied to form grooves 15 inclined to the grooves 14 and is subsequently turned into new positions to form grooves 16, 17 in areas 12, 13 respectively. The grooves are invisible to the naked eye and must therefore be very closely spaced where the object is to be viewed at ordinary reading distance but may be a centimetre apart or more in the case of advertisements. Instead of using a single member 1 to emboss the areas, a series may be used, e.g. one for each area, and where crossed grooves are required, the same area may be impressed twice or the member 1 may have crossed grooves. To provide increased decorative effects, the various areas may be differently coloured, e.g. with vitrifiable enamels, or the surface may be covered with reflecting material such as metal foil. Also, the embossed article may be reproduced by galvano-plastic methods or may be used as an embossing-die or to produce a matrix from which a die may be made. Fig. 10 shows a circle divided into areas by latitude and longitude lines 23, 22, the areas being embossed to provide grid lines 24-28 varying progressively in inclination from the central area of each band to the outer areas to produce a spherical effect. Fig. 10<a> (not shown) represents an opened hollow sphere with a cap. The embossing-member shown in Fig. 11 consists of a disc 30 set in an annular mount 31 which is provided with an operating knob 32 and a pointer 33 and is rotatably mounted in a graduated frame 34.

Title: Gas turbine power plant
IPC: F02C9/32
Filed: 1972-02-14
Abstract: 1361344 Controlling prime movers GENERAL ELECTRIC CO 14 Feb 1972 [26 March 1971] 6754/72 Heading G3R Fuel-flow to a combustion chamber of a gas turbine power plant is servo-controlled by the lowest signal from a number of control loops responsive to different parameters. A further control signal is produced by an additional loop responsive to the lower of two signals representing the load speed and a predetermined power setting in order to limit the output torque. In the arrangement shown, a ship's propeller 8 is driven by turbines 4, 5 associated with a shaft 6, compressor 2 and combustion chamber 3. A pump 15 supplies fuel to the chamber 3 at a rate determined by a servo unit 16, the input to which is the lowest of signals representing average exhaust gas temperature 20, shaft speed 21, acceleration 22, and start-up conditions 23. In addition, line 19 carries a further control signal which may be produced by an amplifier 40 in response to a power setting and actual fuel flow. In a first mode of operation, Docking D, amplifier 40 receives a predetermined minimum power signal 45 and a pump speed signal 41, so that simple governor action is used. Propulsion control levers 34, 35 independently set the propeller pitch through an amplifier 56 and servo unit 54. No torque-limiting takes place. In a second mode, Manoeuvring M, the amplifier 40 additionally receives either a signal from a cubic function generator 39 representing the ship speed and derived from the power setting of the levers 34, 35, or a shaft speed dependent signal from an amplifier 80, whichever is the lower. In this way, the maximum torque is limited when shaft speed drops or the power setting is increased, by reducing the fuel supply appropriately. In this mode, the signal on line 41 includes an actual fuel-flow feedback component from line 19. In the third mode, Sea S, the torque-limiting arrangement of mode M is still employed, but operates only as a standby system for a second propeller pitch control arrangement comprising amplifier 65 and responsive to the sensed speed of shaft 6 which is kept constant at a predetermined power setting by varying the pitch. The amplifier 56 is disconnected in this mode.

Abstract: 1502653 Twisting OKI DENSEN KK 19 Feb 1975 [26 Feb 1974 30 Sept 1974] 7057/75 Heading D1T [Also in Divisions B3 and H1] A method of twisting a wire uses a pair of skew rolls 11a and 11b to transmit and to twist the wire 16. In a preferred embodiment of apparatus for twisting a wire according to said method first 8a, 8b and second 9a, 9b sets of skew rolls twist the wire while a revolving frame stretches the wire beyond its elastic limit to fix the twist. A pair of pinch rollers 4c, 4d, or a set of one movable roll and two fixed rolls (4a, 4b) are intermittently operated to stop the wire untwisting and thus a wire is taken up on the reel 5 which wire is alternately twisted in one and then the opposite direction. Other apparatus for twisting a single wire omits the skew rolls 8a, 8b and/or the revolving frame 3 and a tension between the feed roll 1 and the rolls 9a, 9b is used to fix the twist, possibly by passing the wire over a pin, or through a vibrator. Alternatively an apparatus comprising two sets of skew rolls may replace the revolving frame and the pinch rolls if the orientations of the axes of those rolls are intermittently reversable. An extruding device may be employed before the reel 5 to apply insulation to the conductor. To twist a plurality of wires apparatus is described employing a rotating die and infrared welding of the conductors insulation (Figs. 10-12 not shown).
