Abstract: 1,213,871. Fluidic divider. BERTIN & CIE. 14 Feb., 1968 [14 Feb., 1967], No. 7287/68. Heading G4P. A fluidic divider comprises a first bi-stable circuit having channels 3, 6, 7 and a second bi-stable circuit 10, 11, 12. Permanent flow of fluid is directed to channel 6 by control pressures at 4 or 5, Fig. 1, or by the channel configuration, Fig. 4 (not shown). The fluid circulates in the direction of arrow 21 in vortex chamber 8, and sets up flow in the direction shown in channels 10, 11. When a fluid pulse is applied at 20 it acts through channel 10 to form a vortex in chamber 8, and the back pressure in channel 6 becomes great enough to switch the permanent flow to channel 7. As a result a pulse passes to outputs 16 or 18, and the vortex is stopped. When the pulse at 20 ceases fluid circulates in 10, 11, and 8 in the direction opposite to arrows 23, 22, and 21. The next pulse acts through channel 11 and returns the flow to the directions shown and gives no output at 16, 18. Output 18 may be connected to the pulse input 20 of a similar divider stage.

Title: Improvements relating to firearms
IPC: F41A3/32
Filed: 1946-03-11
Abstract: 609,281. Smallarms. REISING, E. G. March 11, 1946, No. 7518. [Class 119] The breech-bolt 16 of a firearm is moved to its open and closed positions by an action bar 28 into the path of which projects a lever 34 for locking the action bar and breech-bolt in the breech closing position as in Fig. 2, release being effected by a spring 46 which is moved by the hammer 70 and itself then moves the lever 34 on firing. If, however, the round does not fire even though the hammer has moved to the firing position, the absence of a jolt to the firearm permits the frictional contact between the action bar and lever 34 to maintain the lever in its locked position. In the construction shown, the action bar is moved by a hand grip 26, the front end of which engages, when the breech is closed, with a spring which urges the action bar into its frictional contact with the lever 34. The action bar consists of two rods having lugs 52 which by engaging in inclined slots 54 in the breech-bolt urge the latter upwards into locking engagement with a notch 60 in the receiver 12. When the trigger 80 is pulled, a rod 88 connected to an offset portion thereof moves forwards to release a sear from engagement with the hammer 70. The hammer then moves to the firing position under the action of a leaf spring 66, and as the spring rises during this action it enables the spring 46, which lies underneath it, to lift. This lifting of spring 46 causes the lever 34 to pivot against the action of its spring 40 to release the action bar, provided that a shot is fired. The lever 34 may be moved by a finger piece 38 when desired. As shown in Fig. 6, the breech-bolt carries a plunger 96 whose lower end is bifurcated to straddle a reduced part 100 of the firing pin 64. When the plunger is moved upwards by its spring 104 its lower ends engage a shoulder 106 on the firing pin to prevent the latter from moving, but when the bolt is closed the plunger is depressed by the upper wall of the receiver (see Fig. 2) to bring a recess 102 into line with the firing pin, thus allowing the latter to move forwards to fire a shot.
