    Abstract: 1,055,313. Fluid-operated counters. INTER. NATIONAL BUSINESS MACHINES CORPORATION. Feb. 6, 1964 [Feb. 20, 1963], No. 6846/63. Heading G4P. A counting or display device comprises a ring of cavities interconnected with one another through constricted passages, one or all but one of said cavities being filled by a globule of mercury or other high surface-tension fluid, and includes electric or fluid means for indexing the liquid globule round the ring. As shown in Fig. 2 a steady fluid pressure is applied on a line or duct 12 and counting or indexing pulses are received on a line 14. The pulses on the lines 140, 141, 142 etc., which pass into cavities such as 0, 2 which do not at that time contain a mercury globule, pass directly to an outlet 150, 152 etc., to switch the corresponding jets of fluid issuing from the lines 120, 122 etc. from a direction in which they pass down lines 170, 172 etc. into the corresponding cavity 0, 2 etc. to vent outputs 160, 162 etc. The pulse on line 14, is interrupted by the presence of the globule 11 and thus does not pass to the outlet 15, thus the jet from the line 121 continues to pass down line 171 to cavity 1 and thus the mercury globule is indexed to the next cavity. In a modification (Fig. 4, not shown) all but

    Abstract: 1,055,314. Mercury switches. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 5, 1964 [Feb. 20, 1963], No. 6847/63. Heading H2B. [Also in Division G4] An indicator or storage device (see Division G4) comprises two liquid reservoirs interconnected through a constricted passage, one of the reservoirs containing a globule of mercury or the like which can be transferred between the reservoirs A and B by gas pressure. In one embodiment, Fig. 6b (not shown), the devices are arranged in a matrix, and the presence of a globule in one reservoir connects a pair of conductors such as A1 and S1 in a manner similar to that of a crossbar switch.

    Abstract: 1,037,074. Valves. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 5, 1964 [Feb. 20, 1963], No. 6848/63. Heading F2V. [Also in Division G3] A one-way valve, i.e. a valve which permits gas flow in one direction with no substantial pressure drop and prevents or severely restricts reverse flow, consists of a tapered-cylindrical cavity 11, Fig. 1, with the wider end 12 of hemispherical shape but extended by a meniscus-shaped space 13; the end 12 is connected to the opposite or narrow end via a by-pass 21 whilst ducts 15, 16 open into the opposite ends of the cavity 11. A globule of liquid, e.g. mercury, which is disposed in the cavity has such a volume that it assumes a stable spherical-shape under surface tension and occupies the entire cross-section of the wider end 12 of the cavity. If the globule is displaced to the right it is distorted and the forces of surface tension tend to restore the globule to its initial position and shape and so act as loading means. When fluid pressure is admitted to duct 15 it displaces the globule to uncover the by-pass port 23 so that fluid flows to the duct 16. Reversal of flow causes the globule to seal the port 23; if the pressure is very high the globule is forced into the duct 15. The cavity may be of rectangular section and the by-pass duct may be formed by ducts in the cavity wall. The cavity may be restricted beyond the rest position of the globule. In a modification, the by-pass is formed by a tapered-porous plug, the device consisting of two porous elements A, B (Fig. 4, not shown), with a tapering cavity therebetween which houses a further porous member C forming a guide for a globule, the member C having a larger pore size than that of the other two elements which are of the same material and have the same pore size. The globule moves readily in the member C but requires the application of high pressure to be conducted in either of elements B, C. The member C enables liquids of low surface tension to be used; if the element C is omitted then liquid with high surface-tension may be employed.

    Abstract: 1,055,315. Regulating fluid flow. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 21, 1964 [Aug. 21, 1963], No.33622/63. Heading G3H. [Also in Divisions G1 and G4] A bistable device comprises first and second bounded regions separated by a third region containing porous material, a non-wetting globule of liquid, and means for moving the globule between the first and second regions through the third region. A liquid globule is contained within a cylindrical cavity 11 having two zones 12, 13 filled with a first porous material and separated by an intermediate zone 14 filled with a second porous material. Tubes 15, 16 and 19 communicate with the cavity 11 as shown and are closed by porous plugs. The mean cell diameter of these plugs is less than that of the intermediate material which in turn is less than that of the material in the zones 12 and 13. A fluid pressure pulse applied along the tube 15 will force the liquid into the zone 13. For speed of operation the pressure pulse is maintained until the globule has been completely transferred from one zone into the other, but once movement has been started surface tension of the liquid will assist the movement. The position of the liquid globule can be detected by applying pulse to the tubes 15 or 16 and detecting it in the tube 19. This pulse is of considerably less amplitude than the driving pulse. Alternatively the sensing pulse may be applied through the tube 19. A matrix of non-intersecting X and Y pressure ducts may be formed with similar memory devices at the crossing points. In a second embodiment for use as an electro-kinetic transducer the tube 19 and the porous material in the zones 12, 13 may be omitted and metal grids placed at the edges of the intermediate zone. If the liquid is a polar liquid a potential difference will be generated between the grids as the liquid is forced through, the size of the potential difference depending on the speed of movement of the liquid. It is also stated that the intermediate zone may be formed by treating the surfaces of contacting regions of a porous material to give a lower pore size at the contacting surface.

    Abstract: 1,055,312. Electromagnetic switches. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 5, 1964 [Feb. 20, 1963], No. 6845/63. Heading H2B. [Also in Division G4] Switching means serving as an indicator or storage device comprises two or more liquid cavities interconnected serially through constricted passages, a globule of an electrically conducting liquid, e.g. mercury or molten metal, in one of the cavities, at least two electrodes in each cavity between which electrodes a current path can be established through the globule if it is in that cavity so that the current through the globule in the presence of an external magnetic field causes the globule to transfer to the next cavity. A two-cavity device, Fig. 1, having a cross-section as shown in Fig. 2 includes a ball of mercury in a cavity A which is transferred to the cavity B on the occurrence of a current or pulse I through electrodes 21, and returned by a current or pulse I 2 between electrodes 22. Small channels 17 in the walls of the cavities allow an inert gas enclosed with the mercury to pass freely. Alternatively the device may be evacuated.

Three intersecting fluid ducts 18, 19, 22a have wall portions 31, 32 so shaped that fluid entering from the duct 18 tends to adhere to the portion 32 and discharge to the duct 19, and fluid entering from the duct 22a tends to adhere to the portion 31 to discharge to the duct 18. The arrangement is suitable for use in a fluid counter as described in Specification 1, 055, 313.
