Title: Improvements in cartridge feeding-mechanism for automatic or semi-automatic firearms
IPC: F41A9/76
Filed: 1919-01-07
Abstract: 141,128. Fairfax, H. W. Gabbett-. fan 7, 1919. Machine guns; cartridge belts, hoppers, and the like. - Relates to cartridge-feed mechanism for automatic and semi-automatic guns, and consists in the combination with a magazine enclosing an endless chain of carriers mounted to rotate on drums, driven by the reciprocating breech mechanism, of a device for feeding cartridges thereinto from a belt as this is drawn through said device, the action being independent of the number or spacing of any cartridges already in the magazine. In the form shown in Figs. 1 and 3, a magazine of metal, leather, celluloid, or other material encloses a chain A, B of carriers rotatable on drums C, D, the drum C having a rearward extension carrying a drum G formed with a series of cam-slots H engaged by a projection X on the breech-bolt, so that as this reciprocates the carrier A, B is driven to aline the cartridges successively with the barrel. Rotatably mounted on brackets L pivoted externally at M, Fig. 5, on the end-walls of the magazine is a feed-drum J round which a belt of cartridges is adapted to be pulled. Normally, the brackets L are swung down so that this feed device rests in a housing U<1> closed by a flap U. When turned up, an idle wheel P mounted on the rear bracket L and driven by a wheel 0 on the spindle K of the drum J engages a wheel F on the spindle of the drum C, and a tooth Q on the bracket depresses a rod R and opens the cover S of the feed-opening against the action of a spring T. If now the belt be pulled over the drum J in the direction of the arrow, the carrier AB will be rotated, and the cartridges will be lifted from the belt and fed in succession to the carrier by the action of a spring- actuated comb V turning on pivots mounted in the end-walls of the magazine. When a cartridge already in the carrier A, B strikes the heel V<1> of the comb, this is displaced away from the belt so that the corresponding cartridge in the belt is not fed into the magazine. A modification of the external feed device is described having two belt drums, one rotatably mounted on a fixed bracket and the other rotatable relatively thereto, the movement of the latter into its operative position being adapted to uncover the feed aperture of the magazine. A comb is provided for the feed operation, but the drive 0, P is replaced by a ratchetmechanism adapted to be driven by a spring-controlled pivoted arm which is rotated intermittently by the cartridges in the belt as they approach the feed aperture. Specification 128,354 is referred to.

Abstract: 545,062. Controlling electric motors. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 13, 1941. No. 475. Convention date, Jan. 12, 1940. [Class 38 (iii)] In a system for obtaining rapid continuous automatic reversals of a motor 21 driving, for example, a planing machine under the control of tappet switches 19, 20, the motor is supplied by a generator 22 which has a controlled field 24, Ward-Leonard fashion; in the interval between reversals of the field (effected by the forward and reverse contactors 23a, 27a) it is connected across the portion of the series control resistance 29 which was in circuit during the immediately-preceding stroke. In this way, the two different discharge circuits provided ensure the most' rapid decay of the generator field after both forward and reverse drive. These drives are made at different speeds, each depending on the initial setting of the two points 29a, 29b on the field control resistance. The forward running resistance is controlled by the selective relay 30 and contactor 23a; relay 30 has an operating winding 30b and a winding 30a across the generator adequate only to hold the relay closed. Relay 31 provides for reverse running and is similar. Relay 34 ensures that neither relay 30 nor 31 will operate if the generator voltage is below a fixed value. The relays 30 and 31 are under the control of the inter-locked relays 27 and 23 which, in turn, are controlled by the press-button starting switches 35, 36 from which the automatic control is taken over by the limit switches 19, 20.

Patent JP-S5697880-A (JP)
Title: Frequency measuring device
Inventor: NIKI NAOHARU
IPC: H02H3/46
Filed: 1980-01-07
Abstract: PURPOSE: To take accurate measurement even if the frequency of an input signal varies by making it possible to invert the frequency sweep direction of a local oscillator, and by determining a higher harmonic degree by measuring an intermediate frequency and local oscillation frequency twice respectively in sweeps in two forward and backward directions.  
     CONSTITUTION: During the unidirectional sweep of local oscillator 13, intermediate frequency measuring means 17 and local oscillation frequency measuring means 18 take measurements twice simultaneously at an interval of time respectively. Then, the sweep direction of local oscillator 13 is inverted and measurements are taken twice similarly. From measured frequencies F i1  and F i2  obtained by intermediate  frequency measuring means 17 during the unidirectional sweep, and measured  frequencies F l1  and F l2  by local oscillation frequency measuring means 18, higher  harmonic degree (n) is found by using expression I. Next, measurement results  after the sweep direction is inverted are similarly obtained, and the mean value of  the both are calculated to determine higher harmonic degree N. In this constitution,  the higher harmonic degree is determined by averaging two measurement results, so  that even if the frequency of an input signal varies, the accurate frequency can be  measured.
