IPC: A61M25/00
Filed: 1973-10-18
Abstract: 1451465 Surgical drainage device H DUR- AND 18 Oct 1973 48684/73 Heading A5R [Also in Division F2] An injection or drainage device comprises a hollow needle 2 for insertion into flesh. located on one end of a flexible tube 1 by deforming the needle in the region of said one end and using a rigid core 4 in the tube during said deformation. The needle 2 comprises a metallic tube having a tapered end which produces a sharp point at the end opposite to that fixed to the flexible tube 1. The said metallic tube has such a rigidity that it can be repeatedly deformed, thus producing a needle whose curvature can be altered. The flexible plastics tube 1 form the drain of the device and includes a plurality of holes in its sides. The rigid core 4 permits the needle to be .tightly fitted onto the tube, one end of the tube 1 fitting snugly between the inner wall of the needle 2 and the core 4. Thus the outer diameter of the whole apparatus is fairly constant along its length up to the tapered needle portion. The core 4 is either solid or hollow, made of, e.g., polythene, polyamide, p.v.c. or aluminium etc. In an alternative embodiment the needle point is produced by firmly inserting a solid point, e.g. of a metal or hard plastics into the tapered metal tube. Once the needle is inserted into flesh the tube is connected to a syringe or perfusion device for injecting liquids, or a suction device for drainage.

Abstract: 962, 200. Electronic counters; electric selective signalling systems. ADAGE Inc. Dec. 27, 1962, No. 48720/62. Headings G4A and G4H. The output terminals of a cascade counter are connected to read-out terminals through a diode matrix, the pulses to be counted being applied to the counter through an input terminal of said diode matrix. Each stage comprises a bistable device of the type in which a pulse applied to the set or restore side, 16 or 18, respectively, sets or restores the stage, respectively. If pulses are applied to both sides simultaneously the stage reverses. Resetting. A pulse on terminal 10 is applied over vertical bus 32 and diodes such as 70 to restore all stages to normal. Counting. The first pulse at terminal 12 passes through diode 84 and horizontal bus 16 to set stage I. Read out is now effective over vertical bus 34 and lead 87. The next pulse combines with the potential on lead 87 to operate AND gate 88 and pulse vertical bus 36 which adjusts the stages of the counter I-IV to the new setting immediately. The process continues with odd pulses setting stage I and even pulses using logic circuits to adjust the stages according to a desired code (Fig. 2, not shown). The code may be changed by altering the diode connections in the matrix. Reverse count is applied to terminal 14, alternate pulses restoring stage I and using logic circuits to step from one even bus to the next lower odd bus. Terminal 11 is used for setting to 9 capacitors such as 58 provide delay so that a pulse is not counted twice.

Title: Improvements in belt feed mechanisms for automatic firearms
IPC: F41A9/31
Filed: 1963-12-13
Abstract: 995,215. Belt-feed mechanisms. BREVETS AERO-MECANIQUES S.A. Dec. 13, 1963 [Dec. 21, 1962], No. 49344/63. Heading F3C. A belt feed mechanism for an automatic firearm comprises a first rotary element 13 rotated by every recoil of the firearm through an angle corresponding to the pitch of a toothed rotor 14 which is coaxial with the first element. Angular play corresponding to a portion of the complete pitch is provided between the elements 13, 14 which is maintained by a prestressed torsional resilient system such that if during a given power impulse the rotor does not turn through a sufficient angle under the effect of the resilient system the rotor is torsionally urged until the play being eliminated, the first element imperatively drives the rotor by abutment against it. The resilient system is constituted by two torsion bars 15, 16, one inside the other, and connected together at end 18, whilst they are connected at their other ends to the first element 13 and the rotor 14. As shown, the firearm comprises a breech block 3 urged forward by a spring 4 and controlled by a gas tap 5. The whole firearm is mounted on a fixed support 6 on which is mounted the feed mechanism 9. Recoil of the whole firearm with respect to the support 6 actuates the feed mechanism through a finger 4 which acts as a cam between fixed roller 25 and movable roller 26 to move the latter upwardly and so rotate the first rotary member 13 via push-piece 31, pivoted lever 27 and interengaging teeth on the lever 27 and the element 13. The latter is connected through an undirectional clutch to a driving piece 17 which is connected with the above-mentioned play to the sleeve 38 of the rotor via dogs 39 and is also connected to the sleeve 38 via the bars 15, 16 having splined connections with the driving piece 17 and the sleeve 38, respectively. The driving piece 17 is prevented from rotating in the reverse direction by a pawl-and-ratchet device 41, 40. The passage of the last cartridge of the belt past a portion of the rotor permits a spring-loaded lever to be released to actuate means to stop firing. At least two cartridges remain in the mechanism after the firing is stopped. Specification 712,867 is referred to.
