Title: An improved apparatus for making calculations relating to gunnery
IPC: G06G1/00
Filed: 1943-08-04
Abstract: 579,282. Gunnery calculators. KENNEDY, W. D. Aug. 4, 1943, No. 12616. [Class 106 (i)] An apparatus for determining the corrections in respect of wind allowance to be applied to observed data when ranging on a target,' particularly for use when firing rocket projectiles, comprises a crank or eccentric adjustable in respect of the direction and velocity of the wind, an associated linkage, and a pointer or pointers to obtain the bearing correction, the quadrant elevation (Q.E.) correction, or both corrections in accordance with the sinusoidal variation. The apparatus shown in Fig. 1 is used on a plotting table and the changing positions of the target are transmitted to the range-arm 10 through an extension 12. On the axis 11 of the arm 10 is mounted a bush 14 carrying an eccentric pivot pin 15, the distance of which from the axis represents the velocity of the wind. A series of bushes with pivot pins are provided for various wind velocities and different projectile characteristics. The outer end of the arm 10 is formed with a quadrant 16 and carries a pin 17 on which is pivoted a link 18, Figs. 1 and' 2, slotted to engage the pivot pin 15. A pin 21 on the link 18 forms a pivot for a pointer 22 that cooperates with a scale 13 to indicate the true bearing and bearing correction. A slot 23 in the pointer 23 engages a fulcrum pin 44. The correction for elevation is effected by the linkage shown in Figs. 1 and 3. The true elevation is set by a pointer 24 on a scale 23 on the quadrant 16 and the correction is shown on a second scale 26 carried by a rod 28 mounted in suitable guides on the range arm 10 and adjustable by the engagement of its slotted end 29 with the pivot pin 15. The additional adjustment for correction of the bearing with elevation is effected by imparting a movement to the fulcrum pin 44. The pin 44, Fig. 4, is mounted on a sleeve 32 slidable on the rod 28 which carries a transverse slotted plate 33 in which engages a pin 35 on the pointer 24. The Specification sets forth other forms of linkage that may be used to give the corrections required. In order to determine the true Q.E., the range arm 10 is calibrated to represent ground range of target and carries a scale representing height of target at right angles to the range scale and adjustable along it. The Q.E. indicator also has a plate-like extension 60, Fig. 8, with trajectory lines 61 corresponding to different values of elevation, fuzesetting lines 62 and time interval lines 63 in order to determine the fuze-setting and time of night.

A vehicle comprises a hopper a, Fig. 1, a shoot b for delivering material into a sack' c which is suspended from a weighbeam e, and when the' correct weight has been delivered into the sack the weighbeam closes an electric circuit which releases a catch allowing the winch h to be operated to raise' the' sack to' shoulder height, during which time a counting device j is operated, the catch being reset when the winch is reversed. When the sack has received the correct weight, an electromagnet u, Figs. 4, 5, is' energized to attract an arm 8 uniting with lever s which pivots about t removing an arm s1 from the position across the end m1 of the shaft m; an operator can thus press handle k, Fig. 3, inwards to engage teeth n and thus rotate sleeve o carrying gear teeth q and rachet teeth r; a pawl w engages rachet teeth r to prevent reverse motion; rotation of handle k thus winds the rope on drum 4, and lifts the sack, the attachment i, Fig. 2, on the rope anchoring the counter j. When the sack has been lifted, a handle x, Fig. 4, is moved to release the pawl w, which through spring-loaded rod z presses lever s to engage shaft m and decouple the handle k and sleeve o. A permanent magnet v may retain the lever s in the position in which it disengages the shaft m. A leaf spring 6 acts on rod 7 to maintain lever s in engagement with the shaft in until electromagnet u is energized. Specifications 649,109, [Group IX], and 656,520 are referred to'.

Abstract: 653,372. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 28, 1945, No. 13274. Convention date, May 27, 1944. [Class 39 (i)] A cathode-ray tube for use in the detection of angle-modulated, including frequency- and phase-modulated, carrier waves has a composite target including a pair of spaced anodes which occupy a substantial part of the target area and a fluorescent screen which occupies a substantial and continuous part of the target area, and means for deflecting the beam in two directions under the control of a pair of voltage waves, whereby the beam can be caused to trace a Lessajous figure on said target, the anodes and screen being so arranged that approximately one half of said figure is traced on said screen and approximately the other half on said anodes. In the construction shown in Fig. 1 the target comprises a semi-circular fluorescent screen 19 and a pair of spaced anodes 20, 21 in the form of circular quadrants. The electron beam 17 is projected from the gun 9 between two pairs of equidistantly-spaced deflection plates 13-11 and 12-10, one pair of which may be closer to the gun than the other. Electrodes may be located in the tube for focusing the beam on the target. In the construction shown in Fig. 2 the anodes 20, 21 are spaced from the end wall 18 of the tube. The anode 21 may be in the same plane as the anode 20 or in a different plane with the edges of the anodes overlapping.

Patent GB-133361-A (GB)
IPC: F22B1/30
Abstract: 133,361. Revel, F., and Boldorini, A. June 19, 1918. Generating by electricity; feedwater, controlling. -The electrodes in the water of an electrically - heated steam - boiler are separated by insulating - diaphragms having longitudinal openings, thus ensuring that the area for the passage of current between the electrodes varies with the height of the water. The diaphragms also serve, when the boiler is used on locomotives &c., to prevent oscillations of the water-level. The electrode E, Figs. 1 and 2, immersed in the water of a boiler, is surrounded by two concentric cylindrical partitions d, d' made of sandstone, porcelain, quartz, or other insulating-material, the partitions being arranged so that their openings f face in opposite directions. The current passes between the electrode and the boiler walls. The two boilers shown are connected by steam and water conduits. In a modification, Fig. 3, the diaphragm is in the form of an outer cylinder or prism e with inner walls e<1> arranged triangularly. Excess feed-water is discharged, when the boiler pressure rises, through a lift valve normally pressed on its seat by a spring. Boiler water may be discharged through an automatic blow-off valve, the blown-off water being used to heat the feed-water. To prevent the water from rising above the top of the electrodes, the feedpump or feed-valve is so controlled electrically that the feed-supply is stopped when the water rises around an electric contact fixed in the boiler walls.

Abstract: 1,033,334. Sewing. SEWPRIMA Ltd. April 26, 1965 [May 1, 1964], No. 13371/64. Heading D1G. A sewing machine comprises first means connecting the main shaft to a motor for allowing drive to be imparted to the shaft in one sense and also independent rotation of the shaft in the same sense, and second means connecting the shaft to a remote driving mechanism for allowing drive to be imparted in one sense and also independent rotation of the shaft in said one sense. As shown, a pulley 4, driven by a motor via a belt 5, is connected to a sewing machine main shaft 1 by ratchet and pawl means allowing rotation of shaft 1 when pulley 4 is stationary. A pawl housing 18, rigid with shaft 1, co-operates with a ratchet wheel which is journalled on shaft 1 and which may be driven via gearing 17, 21 and a flexible shaft 8 by a friction roller 23 incorporated in a treadle 22 controlling the driving motor. The arrangement is thereby such that when pulley 4 is stationary, roller 23 may be actuated by the operators' foot for rotating shaft 1 to raise or lower the needle. A friction brake is incorporated to prevent overrun of shaft 1 when the drive ceases.
