Title: Machines for broadcasting granular materials such as seeds and manure
IPC: A01C7/02
Filed: 1952-02-19
Abstract: 699,004. Distributing granular material. PETIT, A. Feb. 19, 1952 [Feb. 22, 1951; March 31, 1951; Feb. 5, 1952], No. 4340/52. Class 18 Relates to machines for broadcasting granular material, such as seeds or manure, having a container 1 for the material opening at its lower part into a transverse distributing shoot 21 swept by a paddle wheel 7. According to the invention, the wheel enters merely with the lower portions of its lower paddle arms into a shoot of U-shaped cross-section open at its lateral ends and at its top. The machine shown is carried by the operator who rotates a side handle 9 to drive a shaft chain-geared at 13 to wheel 7. A crank 16 on the driven shaft operates through a connecting rod 17 an agitator 20, Fig. 2, near the outlet 3 of the container the outlet being controlled by the operator through rod 6 upstanding from a sliding plate 5. The sides of the shoot are provided with resilient lining 22 to lessen the clearance for the paddle arms.

Title: Improvements in bistable circuits employing negative resistance devices
Inventor: ALEKSANDER IGOR
IPC: H03K3/315
Filed: 1961-02-06
Abstract: 920,229. Tunnel diode bi-stable circuits. STANDARD TELEPHONES & CABLES Ltd. Feb. 6, 1961, No. 4379/61. Class 40 (6). [Also in Group XIX] A bi-stable circuit comprises a two-terminal negative resistance device having each terminal connected through a resistance to a source of potential and also through a rectifying diode to a source of pulses of the same polarity so that successive pulses switch the circuit from one stable state to another. The Figure shows a tunnel diode TD connected through rectifiers D1, D2, to a source of input pulses of positive plurality. Assuming the tunnel diode to be in a highly conducting state, rectifier D1 is biased to be almost conducting and D2 to be biased well beyond cut-off so that the first positive pulse will pass through diode D1 (but not D2) causing the tunnel diode to switch to its low current condition. Diode D2 is now biased to be almost conducting while D1 is biased well beyond cutoff so the next positive pulse passes through D2 to switch the tunnel diode back to its high current condition. Oppositely phased output pulses may be obtained from the output terminals, differentiating capacitors being provided in the output circuits if required so that output pulses are obtained only at the instants of change-over. In an alternative embodiment (Fig. 4, not shown) an inductor is included in series with resistor R2 so as to assist the change of state and to compensate for capacitative effects and the biasing potentials are obtained from potentiometers connected to a common source. The diodes may be of the gold-bonded or backward type. A plurality of the circuits may be connected together to form a counting-chain.

Title: Improved breech-closing and locking mechanism for gas-operated automatic guns
IPC: F22G3/00
Filed: 1922-02-20
Abstract: 177,497. Sutter, C. March 25, 1921, [Convention date]. Machine guns- Relates to gas-operated guns in which the motor piston J is cennected with the breech - block K by toggle-links D. k<9>, the member k<o> of which forms a locking-dog for the block, and consists in preventing strain on the Jinks by operating the breechblock, in a manner known per se, by a tenon j' on the motor piston engaging with lost motion a recess k<11> in the breech - block. On firing, the initial movement of the piston relatively to the breech - block lowers the dog k' through the link D and the block is then moved rearwards by the projection j<5>, the dog k<9> sliding beneath a rib e<5> on the receiver E. As the breech-block moves to closed position, the locking-dog is pressed upward against an abutment e' on the receiver by a cam i' on the motor piston. The Specification as open to inspection under Sect. 91 (3) (a) also describes (1) the cartridge-feed mechanism which forms the subject-matter of Specification 182,809, (2) the firing-mechanism which forms the subject-matter of Specification 182.127, (3) the muzzle-support which forms the subject-matter of Specification 182,126, [Class 119, Small-arms], (4) a gas-regulating plug valve, Fig. 24 (Cancelled), which has ducts c<12>, c<13>, c<14>, of varying size so that by turning the plug the gas action on the piston may be varied at will. The plug is forced against the wall of its casing by a screw c<8> to prevent leakage of gas. (5). A rear leaf sight H. Fig. 6 (Cancelled) the slide h<6> of which is cylindrical in form, the sight being detachably fixed to the lid G by a projection h<1> and by the feed-lever pin p<9> which is pressed down by the sight leaf spring h<7>. This spring also serves to keep the leaf trunnions h<5> in place; and (6) means whereby the parts of the gun can be readily disassembled. The barrel A is screwed to the receiver E which slidably supports a stock-carrier I fastened by a pin i<3> which is retained by the catch g' of the top cover. The hand guard U is supported in a recess in the front of the receiver and carries a projection u<2> to lock the barrel to the receiver. The receiver is slotted to permit passage of the stud on the cocking piece which is normally retained in forward position by a spring, the stud engaging a recess in the motor piston when the cocking piece is moved to the rear. The firing-mechanism is carried in a casing R detachably engaging the stock carrier I at r and retained by the trigger pin q<2> which is turned by a lever on the outside of the casing R. The stock N is fitted with a pistol grip n<2> and is fixed to the stock carrier by a tube n<5> and bolt n'. The return spring n<9> is held within the stock-carrier by a spring pin n<7>. This subject-matter does not appear in the Specification as accepted.
