Abstract: 1,251,164. Pure fluid switches. INTERNATIONAL BUSINESS MACHINES CORP. 24 June, 1970 [1 July, 1969], No. 30734/70. Heading G4P. A bi-stable fluidic switch has its power jet supplied with air at such a rate that the fluid flow is maintained out of one or other of the output ducts but can be selectively increased. In a first embodiment, Fig. 1, the switch 11 is supplied with air from reservoir 40 via throttled duct 43. If the jet is currently directed to output 14 the flow is insufficient to expand bellows 20, the air venting at 22. When a valve 45 is opened the power jet flow is increased, the bellows now expanding to close electrical contacts 24. As applied to a parallel-serial converter, Fig. 2 (not shown), the parallel-bit output of a tape reader (90) is fed to the control inputs of a corresponding number of fluid switches (51) whose outputs are coupled to a single bellows (61) operating electrical contacts (63). Air is supplied continuously to the power jets at a low flow rate and when the data is to be serialized a further supply of power jet air is connected to each switch (51) in turn via a rotary distributer (73). In a modification, Fig. 3, the switch is asymmetric. The power jet air flow is increased by rapidly closing bellows 108. Subsequent rapid opening of the bellows reduces the air supply to the jet sufficiently to ensure that the jet is directed to output 101 after the bellows have come to rest.

Abstract: 1,253,249. Testing hydraulic brakes. V. L. GOLDSMITH. 8 Jan., 1969, No. 45177/68. Headings F2E and F2F. [Also in Division F1] In an apparatus for bleeding hydraulic systems, a pressure vessel 11 is charged with the volume of hydraulic fluid, a compressed air flexible line 15 is adapted to be connected to the pressure vessel from a source of compressed air (for example the spare wheel 16 of a vehicle) and a liquid pressure line 20 connects the pressure vessel 11 with a master cylinder 1 of the hydraulic system to be serviced. In operation, when a valve 18, associated with the spare wheel connector 17, is opened the hydraulic fluid in the pressure vessel 11 is forced through the liquid pressure line 20 to a cap 21 which is adapted to be screwed on to a master cylinder reservoir 1 of an hydraulic braking system when the normal screwed cover 3 is removed. The hydraulic fluid then passes through a supply line 4 leading to an hydraulic wheel brake cylinder 5 to be bled through a bleed screw valve 9. When the hydraulic circuit is free of air bubbles the bleed screw valve 9 is closed and the valve connector 17 is removed. The whole operation may be conducted by a single operator using the above apparatus.

Abstract: 1,258,170. Differential gas lift systems. BAKER OIL TOOLS, Inc. Sept. 10, 1969 [Nov. 25, 1968; Dec. 2, 1968], No. 44706/69. Heading F1R. Apparatus for gas lifting liquid from a deep well comprises a pilot valve S set to operate at normal (high) pressure difference between the interior of the tubing string T and the casing (W), and a main valve R, set to operate at a lower pressure difference, both valves being attached to the outside of the tubing string. The valves may be separate or, as shown in Fig. 7, incorporated in one housing 24, attached to the outside of the tubing string T. The combined valve comprises orifices or chokes 30, 69 and 65, an outlet 22, a main valve member 29 moving in a housing 24, between a position closing passage 27 and engaging stop 36, the main valve member 29 acting as a housing for pilot valve 60 which moves between a position closing passage 61 and engaging stop 71, the housing 24 having a check-valve seat 81 to prevent liquid flow from outlet to inlets when the valve element, 80, is engaged in the seat. The valve 29 holds element 80 off its seat when closed and has a groove to permit pressure in the tubing string to act on the valve. The areas of the valves 29, 60 exposed to pressure in the tubing string, the areas subjected directly to pressure in the casing and the areas indirectly subjected to pressure in the casing, through chokes 30, 69 and 65, and the pressure of spring 38, are so arranged that the pilot valve S opens at high differential pressure followed by the main valve R. When a slug is discharged the pressure in the tubing string falls and the velocity of flow through the chokes 30, 65 and 69 increases, so decreasing the effective pressure, whereby reliable closing of the valves R, S is ensured.

The method is commenced by passing the liquid down the tower at a rate sufficient to ensure that the height of the crest of the liquid phase on each baffle where the liquid phase overflows the edge of each baffle is stable and the crest is of substantially uniform height and is continuous along the said edge, so that the liquid phase overflows the edge of each baffle in a respective continuous curtain immediately adjacent said edge, and supplying the gas or vapour phase upwardly through the tower. The conditions of the process are chosen such that the liquid phase overflowing the baffle edges is dispersed into discrete droplets or froth by high velocity gas phase in the vertical spaces between adjacent adjacent baffles, and a decreased gas phase velocity is obtained in the open areas of the baffles permitting the major part of the liquid droplets as froth entrained in the ascending gas phase to coalesce and separate under gravity from the ascending gas phase. Examples relate to the steam stripping of gases from solutions. Examples also relate to stripping ethyl alcohol from sulphate and sulphite waste liquors with steam.

Abstract: 1315958 Counting fibres IMPERIAL CHEMCAL INDUSTRIES Ltd 7 Oct 1970 [14 Oct 1969] 50472/69 Heading DIF Apparatus for detecting and counting overlength fibres in a longitudinally oriented fibre assembly, e.g. sliver, roving or top, comprises means for gripping the assembly at a predetermined distance from its leading end and withdrawing gripped fibres from the assembly, means for straightening the gripped fibres and means for counting the straightened fibres at one or more predetermined distances from the gripping means. In operation, the fibre assembly is intermittently forwarded between aprons 1, 2 towards the gripping means 5. The gripping means 5, comprising fixed upper jaw 6 and movable lower jaw 7, is advanced towards the aprons 1, 2 by a pnuematic piston and cylinder or a linear motor 9. The jaws 6, 7 close to grip the fibres and the gripping means 5 is retracted to withdraw fibres from the assembly. The gripped fibres are sucked into a slit 14 between a pair of transparent, e.g. glass, plates 12, 13 by means of suction applied to a container 10 or duct 11. The gripped fibres are thus straightened and are counted by means of a scanning photoeleectric cell and associated light source placed on opposite sides of the plates 12, 13. The impulses of the photoelectric cell are transmitted to a digital cumulative counter 18. The gripped fibres are then released and conveyed to the container 10 via the duct 11. The process is repeated. A plurality of photoelectric devices can be used to count fibres of different lengths in the gripped sample. The collected fibres can be weighed to correlate the fibres of a predetermined length to the total weight of fibres withdrawn. A clearing device such as a knife may be operated when the fibres are released to ensure that all fibres are released from the jaws 6, 7 and also that any overlength fibres not withdrawn from between the aprons are severed. Alternatively or in addition, the photo-electric device can perform a scanning operation on release of the fibres, any impulse due to a remaining fibre or impurity activating an alarm or stopping the apparatus.
