Abstract: 1350687 Electrolytic coulometers SANYO ELECTRIC CO Ltd 19 April 1971 [4 Feb 1970 16 April 1970 14 Dec 1970] 21079/71 Heading G1Q The electrodes 2/3 of an electrolytic coulometer are disposed in recesses in a solid electrolyte 1. The coulometer is formed by moulding powdered materials, and is of the type whose terminal voltage rises suddenly when an active material which had previously been transferred from one electrode to the other has been completely transferred back. In one embodiment, Fig. 3, the electrolyte is Ag3SI and each electrode comprises a layer 3 of carbon and a layer 2 of Ag, Ag-Hg amalgam or a mixture of Ag-Hg amalgam and the electrolyte material. In another embodiment, Fig. 4, (not shown), the electrolyte is Ag3 SI. HgI2, one electrode is Au and the other is a mixture of Ag or Ag amalgam, the electrolyte material and Te or Se. The presence of the Te or Se causes the coulometer to behave partly like a -0.2v battery, so that in use its voltage is negative during both the initial transfer and the transfer back of the active material, only becoming positive when the sudden rise occurs.

Title: Improvements relating to the winding of elastic yarns
Inventor: MELDRUM JOHN IRVING
IPC: B65H54/42
Filed: 1962-06-01
Abstract: 1,048,126. Winding yarns; reducing tension. COURTAULDS Ltd. Aug. 29, 1963 [June 1, 1962], No. 21159/62. Headings DID and D1J.  Tension in an elastic yarn is relaxed as the yarn is being wound on to a package. Yarn 8 is drawn by a belt having a series of transverse ridges 4 and wound on a package 6 driven by frictional contact with the belt. The yarn 8 contacts the belt as it passes round a pulley 3 and leaves the belt and is wound on the package 6 at the commencement of the upper straight run. Since the spacing of the ridges 4 is greater as the belt passes round the pulley 3 than on the straight upper run the tension is reduced or even completely relaxed as it is wound on the package. The degree of reduction in tension depends on the height of the ridges and on the radius of the pulley. A traverse guide 9 distributes the yarn over the length of the package 6. In an alternative embodiment, the belt has no ridges but is extensible and is driven at a greater speed in the initial yarn contacting region than in the region of the package.

Title: Airborne communications and information transfer system
IPC: H04B7/185
Filed: 1973-05-04
Abstract: 1431485 Radio repeater systems; aerials R S CESARO 4 May 1973 21254/73 Headings H4L and H4A Three or more independent antennae 76, 94, 118, Fig. 4B, mounted on coaxial, independently rotatable tubes 50, 52, 54, Fig. 4A, serve separate functions in an airborne radio relay station (10, Fig. 1, not shown). The antenna assembly hangs from a ball-and-socket joint 34; the tubes are rotated by gears 68 &c. from motors 66 etc.; and slip rings 132 &c. connect the antennae to the relay circuitry. The antennae 76 are spiral (Fig. 5, not shown) and communicate with a ground control station (22) to which the balloon (10) is tethered, to provide orientation control for all the antennae 76, 94, 118 as well as communications information. The antennae 94 (Fig. 6, not shown) are dishshaped and communicate with all "local" ground stations 24 in the service area (A) of the balloon 10, for information transmission and reception. The antennae 118 (Fig. 7, not shown) are parabolic-cylindrical and communicate with the next airborne relay station in a chain (Fig. 2, not shown) thereof. The transmit-receive circuits associated with the three antennae are generally similar, but with certain differences. The ground transmitters change the signal frequency through a UHF intermediate frequency to an X-band for transmission (Fig. 8, not shown); the ground receivers have an extra intermediate (S-band) frequency (Fig. 9, not shown). The air-to-air transmitter-receivers (Figs. 12, 11, not shown) omit the signal frequency stage, dropping only to UHF, and the receiver uses an L-Band stage instead of S-Band. The airborne transmitreceive communication with the control station (Fig. 13, not shown) is similar to the air-to-air circuitry but includes telemetry and monitor circuits. The ground receiver (Fig. 9, not shown) includes selectable local oscillators (171, 198) which enable the signal frequency mixer (232-1, 232-2 &c) to correct inversion of the received signal in cases where this matters, such as the relaying of "spread spectrum signals" which must not be inverted by an odd number of hops.

Abstract: 974,211. Removing detergents from waste-waters. GENERAL MILLS Inc. May 29, 1963 [June 8, 1962], No. 21498/63. Heading C1C. An aqueous liquid containing an anionic waste, particularly a detergent, is treated with an acidic treatment solution of trioctylamine in vegetable oils, kerosine or fuel oil. The separation of the two phases is aided by aeration, which also may biologically degrade the detergent. The treatment liquid is regenerated by reaction with an alkaline saline solution and the detergent and any sludge is discharged being now more easily disposal sewage. An aqueous liquid containing a detergent is introduced at predetermined velocity, to injection mixer 12 by inlet 11. Treatment liquid from tank 14 and available-quantity control tank 18 is injected by inlet 21 and an acid from tank 23 is also sucked in by way of line 28 to give a treating liquid of predetermined composition. The mixture of aqueous and treating liquids is conducted to spray device 34 to be discharged into treating tank 36 at the beginning of a tortuous flow path and with the added effect of gas supplied through spargers 52 separates into purified aqueous phase discharged at 54 and organic amine/detergent phase discharged to mixer 62 via pipe 61 under the control of float 66. Caustic solution from tank 63 is drawn into the mixer and the mixture separates into the regenerated organic phase stored in tank 71 and waste discharged via weir 73. Any sludge is removed by tap 83, screw-type skimmer 84 and screw-conveyer 87. The mixer and slude removers described may be replaced by other types. In Fig. 2 (not shown) the apparatus is modified in respect of the mixer 62, the spray device 34, the aerators 52, the baffles 37 and the weir 73.
