Title: Improvements in Breech Mechanism for Ordnance.
Inventor: ADELMAN ARTHUR
IPC: F41A5/32
Filed: 1916-09-07
Abstract: 109,303. Adelman, A., and Stambaugh, H. J. Sept. 7, 1916. Ordnance breech mechanism.-Relates to semiautomatic breech mechanism of the kind in which the breech-closing spring is energized during recoil by a cam-device and the breech is automatically opened during run-out, the breech-closing spring being locked against action on the breech-operating shaft until the extractors are able to perform their function of locking the breech-block in the openposition. The invention consists of energizing the breech-closing spring during a portion only of the recoil, the spring Leing then locked in the energized condition. Fig. 2 is a plan of the breechend of the gun, showing the barrel A in the firing position, and Fig. 3 is a side elevation showing the gun barrel in its partly recoiled position, the breech closing spring 64, being energized and locked. The vertically sliding breechblock 42 is actuated by an arm 44 carried by a transverse shaft 45, to one end of which is attached a hand-lever G, the other end carrying a crank-arm 83 having a roller 86. Loosely mounted on the gun, co-axially with the shaft 45, is a lever E carrying a roller 61 and connected by a chain 67 and rod 65 to the spring 64. The lever G is held behind a stop 92 on the gun by a latch 74 which is connected to a trip-lever 81. On recoil, the roller 61 on the lever E engages a camsurface 70 and thereby energizes the spring 64, which is then held stressed by the engagement of a projection 50 on the lever with a spring-controlled stop 94 on the gun. During the run-out, the trip-lever 81 engages an incline 82 and releases the lever G, and the roller 86 then engages a cam-surface 88 to lower the breech-blocks gradually, the last part of the movement of the lever G causing the release of the spring-retaining member 94, so that the breech is free to close automatically when the extractor is rocked by the insertic.n of a fresh cartridge. The mechanism may be adapted for hand operation by removing the spring casing 62 and pushing inwards the rollers 86, 61 so as to house them, as shown in Fig. 21. Modifications are described in which (1) a verticallyarranged spring, energized by the closing of the breech, is adapted to open the breech when the lever G is released; and (2) the cams for energizing the clcsing-spring and opening the breech are both arranged on the right-hand side of the gun.

Abstract: 1509611 Electronic timepieces CITIZEN WATCH CO Ltd 26 March 1975 [1 April 1974] 12777/75 Heading G3T [Also in Division H2]  An electronic timepiece with liquid crystal display of hours, minutes, seconds, date, day and AM/PM is provided with a voltage booster circuit 4 Fig. 3 using two-phase signals #, # derived from a frequency divider chain F D1 , a potential level adjuster circuit 3 including a transistor T r1 , R 64  and an MOS-resistor R 64  for matching the output of the frequency divider F D1  to the input of an integrated circuit 6 comprising time counter means, decoders and display drivers and means including a setting switch unit 8 for setting and correcting displayed data. The divider F D1  receives pulses at 32768Hz from a tuning-fork crystal controlled oscillator circuit 1 and produces pulses at 64Hz which are applied via the potential matching circuit 3 to a further frequency divider 11 Fig. 4 in the I.C. chip to produce a 1Hz signal. The 1Hz signal pulses are fed to a seconds counter 12 and from thence via a correction gate circuit 301 to a minutes counter 13. An output of 13 is fed via a correction gate 302 to an hours counter 14 which applies outputs via correction gates 303, 304 to a day of the week counter 16 and a date counter 15. The counts in the minutes and hours counters are decoded in decoders 19, 18 respectively and the counts in the seconds and date counters 12, 15 are decoded in a decoder 17. The outputs of the decoders are applied to drivers 20, 21, 22 respectively and the output of day counter 16 is applied to a driver circuit 23. The drivers activate selected segments of the liquid crystal display devices 7. A flip-flop 24 produces a 32 Hz from the 64Hz output of divider F D1  and a control unit 25' activates the display elements with 32Hz alternating current via the drivers. Setting. For fast correction of the minutes, hours and date displays a 1 second signal is passed to the respective counters by a respective correction gate circuit 301, 302, 304 when respective terminals R 2 , R 3 , R 4  of switch unit 8 are switched to a high potential. The 1 second signal may also be applied to the time of day ring counter 16 via gate 303 by switching a terminal R 5  to high potential. The 64Hz signal is applied via respective gates to reset the counters to zero. A colon-dot display turns ON and OFF each second. The same display devices are used for seconds and date. The voltage booster circuit 4 Fig. 3 is a Schenkel type voltage multiplier having a multiplication factor of four and which has a 2-phase input at 1024Hz from the f-divider F D1  and charges a capacitor C ss  to 5 volts. The power supply may be a solar cell in combination with a chargeable or non-chargeable battery.

Abstract: 615,341. Self-adjusting tappets. WEATHERHEAD CO. April 29, 1946, No. 12823. Convention date, May 3, 1945. [Class 80 (iii)] [Also in Group XXVII] A self-adjusting compression link or tappet for automatically taking up slack in a mechanism and particularly applicable to tappets for the cam-operated valves of internal-combustion engines comprises a hollow cylindrical member 22 with a head 18 co-operating with a cam 17 and a plunger member 23 slidable within the bore of the member 22. A differential piston 26 also operates within the said bore and a smaller bore of the plunger to define chambers 24 and 25 which are filled with hydraulic fluid and are in communication through a restricted passage 31. The piston 26 is urged by a spring 36 to force the fluid from chamber 24 to chamber 25 to take up any slack or clearance developing when the compression forces are removed. When the tappet is actuated to lift the valve 12, fluid in chamber 25 is trapped by the restricted passage 31, which may also be controlled by a non-return valve 45, to act as a solid link to transmit the thrust. No appreciable contraction of the tappet due to leak-back through the passage 31 occurs owing to the normally short operating period. With the addition of a non- return valve as in Fig. 2, a small leak passage 47 is still provided to ensure that the length of the tappet is not maintained too long on expansion of the valve rod so that it prevents the valve seating properly.
