Abstract: 212,698. Armstrong, Whitworth, & Co., Ltd., Sir W. G., Hadcock, Sir A. G., and Forster, G. Jan. 26, 1923. Ordnance breech mechanism.-Relates to breech mechanism actuated by a piston and cylinder arranged longitudinally alongside the gun. According to the invention, the piston 13, Fig. 1, is connected by a universal joint 17 to a bracket 18 on the gun, and the cylinder 14 is connected by another universal joint to a crank 15 on a shaft 16 on the breech-block carrier 12. The cylinder is connected to supply and exhaust through passages 130, 131 in the piston rod. The first part of the action of the piston and cylinder is to rotate the shaft 16 to unscrew the breech-block, after which the continued action of the piston and cylinder swings the carrier 12 out about its hinges 120, the universal joints allowing for the swing of the piston and cylinder in the two directions required by these operations. The shaft may rotate the breech-block by means of a bevel pinion 160, Fig. 6, and may be provided with a finger 162 for locking the breechblock in the locked position. In a modification, Figs. 9 and 11, the cylinder 14 is connected to a bell-crank lever 32 mounted on the breech-block carrier and jointed' to the breech-block by a link 34, a slide 35, and another link 351. The breech mechanism may also be worked by hand. In Fig. 1, a hand wheel 23 is connected through suitable gearing 230 and a link 231 to lugs 121 on the carrier 12. In Fig. 5, a hand-wheel 28 operates a continuous chain 27 connected by a link 25 to the cylinder 14. In Fig. 9, a handwheel 38 is connected through gearing and a clutch 42 to a rack 37 linked to the bell crank 32 by a connecting rod 370. When fluid pressure is supplied to the piston and cylinder for power operation, it is also supplied to a ram 44, which acts on a bell-crank lever 43 and throws the clutch 42 out of action. Where space is limited, as in the case of the central gun in a triple gun mounting, the hand mechanism comprises a lever 450, Fig. 12, containing a sliding key rod 45 adapted to engage successively in two notches 46 in a boss 47 on the fulcrum of the bell-crank lever 32, the rocking of the bell-crank lever being performed by two successive throws of the lever 450 with the key 45 engaged in the successive notches respectivly; the first stage unscrews the breech-block and the second stage swings it open. The fluid pressure valves are operated by a handle 48.

Abstract: 915,205. Radar; aerials. NORTH AMERICAN AVIATION Inc. Jan. 22, 1959, No. 2490/59. Class 40 (7). [Also in Group XL (b)] A centre-feed bridge for a pulse radar antenna has four channels and means for comparing the phase and amplitude of signals received in those channels. Four channels 9, 10, 11, 12 project from a reflector and turn round as at 16 to illumine the reflector through apertures B, A, D, C respectively. The amplitude difference between signals in A and D or B and C gives the elevation error, the phase difference between signals in A and B or D and C gives the azimuth error, and the in-phase component of the signals gives the range. The radiation pattern has a central lobe surrounded by four lobes in the form of a horizontal wedge. In the region 20 of the bridge, channel 10 contains a - 90 degree and 12 a +90 degree phase shifter; in 21 there are top wall couplers between channels 9 and 10 and between 11 and 12; in 22 there is a +90 degree phase shifter in channel 10 and one of - 90 degrees in 11; in 23 there are side slot couplers between channels 9 and 12 and between 10 and 11, and an adjusting screw. The range signal appears in channel 9, the elevation error in 12, and the azimuth error in 11. Alternative arrangements of the phase shifters are described. The apertures A, B, C, D are located near the focal point of a reflector, Fig. 3 (not shown).

Abstract: 347,287. Printing-machines. RANGER, A. W., 86, Hatton Garden, London. Jan. 27, 1930, No. 2810. [Classes 100 (i) and 100 (ii).] Platen presses; gripper mechanism ; sheetregistering devices.-In a platen press in which the sheets are fed to the platen 4 and delivered therefrom by means of grippers 5, 6, Fig. 5, on intermittently rotated arms 1, Figs. 1 and 4, the grippers are operated to release the sheets momentarily while on the platen 4, and the sheets are thereupon registered just prior to the printing operation by means of one or more lays 34, 35, which are moved to engage the sheet and set it in a predetermined position for the printing operation, after which the grippers again seize the sheet and carry it to the delivery position, the lays being moved out of the path of the sheet as it is removed by the grippers. The gripper members 5 are carried by hinge pins 20 which are operated by lever-and-link mechanism 27, 23, 22, 21 from a cam 10 freely mounted on a shaft 3, the cam 10 being oscillated in known manner by lever-and-link mechanism from a spring- controlled lever 13 actuated by a cam 11 on a shaft 12. To open the grippers during the printing operation to permit of the sheet registration, additional rises 33, 32 are formed in the cams 11, 10, and the rise 32 may be constructed in such a manner that it can be put out of operation when the press is used for printing several sheets simultaneously or for work which does not require accurate registration. The lays 34, 35 are mounted on shafts 36, 45 which are connected to bevel gears 50, 51 for simultaneous operation. This operation is effected by a cam 58 on the shaft 12, and a spring-controlled lever 54 fitted at ibs end with a cam plate 88 which engages a roller 53 on a crank arm 52 fitted on the shaft 45. Springs 43, 48 tend to move the lays towards the edges of the platen, and the cam 58 moves the lays away from the platen. The shafts 36, 45 are mounted in brackets 41, 39, 48 fixed to the platen. The movements of the lays may be controlled by stops 44, or by finely threaded screws, and the lays may be fitted with light springs 49 supported by stronger springs 96, the sheets being engaged by the springs 49. The shafts 36, 45 may be operated independently by separate cam plates on the lever 54. Yielding spring blades may be fitted on the bottom lays 35 to prevent sagging of the sheet due to its extension over the bottom edge of the platen.
