Title: Improvements in or relating to exploring devices for use in television, photo-telegraphic or like systems
IPC: H04N3/04
Filed: 1930-02-17
Abstract: 345,770. Television. WILSON, R. G., Solheimar, Shackleford, Godalming, Surrey, and WATERS, A. A., 16, Selbourne Road, Luton. Feb. 17, 1930, No. 5248. [Class 40 (iii).] An exploring device embodies a pair of similar cylinders or rollers 1, 2 of equal diameter, eccentrically mounted on spindles 3, 4 and separated by a small gap 5, which, during the rotation of the cylinders at equal velocities in the same direction by gearing 6, 7, 8, describes an oscillatory motion in the plane of the axes 3, 4. The exploration is effected by a beam of light from a source 9 in conjunction with the gap 5, and straight or curved slits 11 in a disc 10 rotated at any desired speed relative to the cylinders 1, 2. The disc 10 may be replaced by a second pair of eccentrically mounted cylinders with their spindles perpendicular to the spindles 3, 4, but lying in a plane parallel to that containing the spindles of the first pair. The second pair of cylinders, when rotated, produce a gap whose oscillation is perpendicular to that of the gap 5. The cylinders are dynamically balanced for rotation about their axes 3, 4. Between the exploring device and the object scanned or the viewing screen, an optical system with a convex cylindrical lens having different focal lengths in two planes at right-angles may be employed.

Title: Improved electrical process for breaking emulsions
IPC: C10G33/02
Filed: 1950-03-02
Abstract: <PICT:0680244/III/1> A process for breaking an emulsion comprises subjecting a stream of the emulsion to an electrical field in an initial zone and passing it to a secondary settling zone wherein demulsified constituents are separated, any unbroken emulsion being also separated and returned to the initial zone.  Hydrocarbon oils containing salt may be desalted by forming an aqueous emulsion, which is then broken as above to separate the aqueous phase containing the salt.  In Fig. 1 a hydrocarbon oil containing salt is introduced into the apparatus by line 1 and water by line 2, and the mixture is heated to 200 DEG F at 25 lbs. sq. in. pressure.  The pressure is reduced to about atmospheric by passing through valve 3, and an emulsion is thus formed; this is passed into zone 10 between electrodes 4.  The oil phase formed is passed by line 5 to the top of settling zone 20, and the water phase by line 6 to the bottom of this zone, and both streams flow longitudinally through the zone between baffle elements 7 which are sloped slightly upwardly to permit the aqueous phase to flow back to the bottom of the zone from where it is removed by line 12.  The desalted oil is removed by line 11 and an emulsion phase withdrawn from the middle of the zone by line 13 is recycled to line 1 for further treatment in zone 10.  In a modification, the separation zone is integral with the electrical zone and is positioned so that any unbroken emulsion tends to circulate back to the electrical zone.  The oil and water mixture may be heated to 150 DEG -350 DEG F and maintained at a pressure of 25-200 lbs./sq. in. Demulsification agents such as surface active agents or electrolytes such as sodium hydroxide may be used to assist the breaking of the emulsion, and the voltage employed may be 5,000-35,000 volts.

Title: Multiplex switching means
IPC: H04J3/04
Filed: 1954-02-26
Abstract: 753,870. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Feb. 26, 1954 [March 12, 1953], No. 5731/64. Class 40 (4). In a multiplex switching system in which a number of paths may be gated to a common path at different instants in a cycle, cross-points of a cross-bar switch are operated to record the identities of the individual paths and therefore of the position of the corresponding instants in the cycle, and for feeding pulses at said instants to wires controlling the appropriate gates. As shown, the common path R1 may be connected at different instants to any of one hundred paths, of which four, 11, 12, 21, 22 are shown, over gate circuits P1l P12, P21, P22. Each gate circuit is opened only if potential on two control leads (one tens and one units lead), e.g. T1 and U1 for P11 is lowered simultaneously. Each pulse source V5 provides a negative-going pulse having a different position in the cycle and is associated with one of the hold magnets CM1 . . . CM20. Thus if the outlet 11 is to be associated with the common path R1 in the time position of the pulse source associated with CM1 the select magnets TM1, UM1 are operated and also the hold magnet CM1, the magnets TM1, UM1 then being released. The pulse source V5 is thus connected over decoupling rectifiers RES, RE6 to the control leads T1, U1 for gate P11 which is thus opened in the required position in the cycle. Instead of using two groups of ten control leads, more groups may be used, e.g. three groups of 5, 5 and 4 leads may be used. Alternatively each tens digit may be represented by a combination of 2 out of 5 control leads, each lead then containing a decoupling rectifier. As a further alternative the gates may be controlled by three wires taken in different combinations from a set of ten wires. Construction of switch. Since only one contact needs to be made at each cross-point the operating bars themselves are made to carry the current. As shown, Fig. 2, a select bar 1 capable of moving vertically is provided with a frusto-conical projection 2; and a hold bar 3 capable of moving perpendicular to the paper is provided with a resiliently mounted rod 4. The select bar 1 is first operated to move the projection 2 up to the level of the line 5 and the hold bar is then moved into the paper so that the rod 4 rides up over the conical part of the projection. When the select, bar is restored the rod 4 is deflected downwards and maintains contact with the projection 2, so maintaining the electrical connection between the bars 1 and 3 until the hold bar 3 is restored. The hold bar 3 may consist of a number of insulated segments, e.g. two such segments if required for the embodiment of Fig. 1. Specifications 681,330, [Group XL (b)], and 705,839 are referred to.
