Abstract: 873,599. Mixer-settler liquid contacting. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 21, 1958 [Sept. 2, 1957], No. 27629/57. Class 46. In the partition of liquids between two phases, the mixersettler apparatus, with mixer compartments 10 and settler compartments 11, has interconnecting ports 13, 14 and 15, for mixed phase, aqueous phase and solvent phase, respectively anti-swirl baffles 16 and inlets and outlets 25 to 28, for the aqueous and solvent phases. The mixed phase ports 13 are shown in the form of rectangular slots and are each covered by a rectangular member 17, Fig. 2, with a rectangular hole 18 smaller than the associated port 13, but exposing part of it. The members 17 are movable in grooves 19, Fig. 1, so that the position of the hole 18 relative to the post 13 may be varied because the height of the hole 18 determines the ratio of flow rates through and at which the mixer-settler will remain in stable operation with the interface between the solvent and aqueous phase below the level of the hole 18. The ports 14 are shown as part annular and are covered by circular members 20 having a hole in line with the crescent shaped port 14. The circular member 20 is fixed to the settler compartment by a bolt 23 and also carries a bent tube 24 covering the hole and pivotting about axis X-X. This arrangement provides an adjustable underflow weir, the height of the weir being adjusted by rotating the member 20.

Title: Improvements in or relating to course-indicating apparatus
Inventor: CUTLER ALBERT ERNEST
IPC: G01C21/00
Filed: 1953-10-01
Abstract: 777,425. Electric correspondence control systems. COMMUNICATIONS PATENTS, Ltd. Sept. 24, 1954 [Oct. 1, 1953], No. 27664/54. Divided out of 777,424. Class 40 (1). [Also in Groups XIX and XX] A recorded course is marked at selected intervals of time by giving the recording element a small periodic transverse displacement and at longer intervals of time by giving the recording element a different displacement. The course recorder proper is described in Specification 777,424. The recording head follows the course of an aircraft and this course 35 is recorded by pen 22. A second track 38 represents the height of the aircraft with respect to another aircraft as described in the above-mentioned application. The time scale comprising short marks 36 and long marks 34 at longer intervals is produced on track 35 by the mechanism 23. This mechanism comprises two solenoids 27, 28 (Fig. 4) with a common armature 29, which is supported by springs 30 and carries the recording pen 22. The solenoids are connected in the timing circuit shown in Fig. 8. This comprises a rotary stepping switch 39 which has 64 contacts traversed at one revolution per minute by a wiper 40, and a single contact 47 and an unconnected arc 46 traversed in the same time by a second wiper 48. The 64 contacts are connected to a selector switch 41 as shown, and this selects the time interval for the shorter marks at 1/64 (top contact of switch 41), 1/32, 1/16, 1/8, 1/4, 1/2 or 1 minute (bottom contact of switch). The switch 41 has a movable arc 42 which connects all contacts corresponding to a longer time interval than that selected. A source of potential is applied to wiper 40, and thus relay 44 is caused to operate at the frequency selected by switch 41. The relay 44 has a contact 45 and this energizes solenoid 27 at the selected frequency. Each time solenoid 27 is energized one end of the armature 29 is pulled down and the pen makes a transverse mark 36 on the record track. Larger marks 34 are made at minute intervals by wiper 48 engaging contact 47 on rotary switch 39, which then supplies current also to solenoid 28 causing both ends of the armature 29 to be drawn down and the pen to make a larger mark.

[Class 38 (iv)] In an internal-combustion engine starting system in which the starter motor switch 4 is operated electromagnetically and is automatically opened when the engine becomes self-operative, means, e.g. a resistance 13, are provided whereby the energization of the electromagnetic switch may be limited to a holding value. The circuit of the winding 7 operating the starter circuit switch 4 is closed through a resistance 13 which may be short circuited manually or by a diaphragm switch 16 sensitive to engine suction which is provided with a time delay in the form of a screw 25 in the connection 24 to the engine manifold. The resistance 13 is of such value as to allow the coil 7 to hold the switch 4 closed but not to operate. it when it is open. The switch member 4 may also operate the starter pinion to engage the engine fly-wheel. The connection of the winding 7 to the battery is completed through the engine driven generator G so that when the engine becomes self operative the coil 7 is de-energized. Reference has been directed by the Comptroller to Specification 396,076.

Abstract: 1,187,093. Valves. CHANTIERS NAVALS DE LA CIOTAT, J. P. FILIPPI, and M. E. ZUCCA. 16 June, 1967 [21 June, 1966], No. 27919/67. Heading F2V. A time-lag device formed by restriction 11 and capacity 12 is combined with a fluid relay 1 which has a chamber 2 with an outlet c, a vent port e and a port d connected to a source of supply pressure 13. A closure member 5 hinged to a wall 4 is actuated by a diaphragm 8 between chambers 6, 7 to alternately open and close the ports d, e. Supply pressure is connected to chamber 7 at port b and acts together with spring 9 to bias diaphragm 8 and closure 5 to position shown. Pressure in line 10 delayed by the time-lag device acts on diaphragm 8 via port a of the chamber 6 to start the closure member 5 moving to open port d. As soon as the port d is partially open chamber 7 is vented to atmosphere through port e and so the diaphragm quickly moves upwardly to open port d completely and close port e. The supply pressure is thus connected to outlet port c. Spring 9 can be placed in the chamber 6. Ports b and c may be interconnected in which case the supply pressure is connected to port e. The outlet pressure from one valve can be used to control a second valve.

Abstract: 1466585 Winching wire KOBE STEEL Ltd 24 June 1974 [23 June 1973] 27929/74 Heading B3E [Also in Division B8] In winding a wire helically on a core, e.g. an annular core, by moving the core along a path and rotating a wire supply about that path, the leading end of the wire is prevented from rotating about the path by engagement with a guide extending alongside the path. Fig. 1 shows a part 3 of such a guide over which the bent end 2a of the wire is engaged. The guide may be a strip or rod or be of channel section. Instead of bending the leading end of the wire, a suitable shaped end piece may be attached to the wire. Fig. 6 shows a gap in the guide between parts 8, 9, through which the portion 2d of the wire which is being wound on to the core 1 can pass in the course of rotation of the supply as shown by arrow X. The leading edge 2a of the wire passes off part 9 on to part 8 as the core revolves. Alternative configurations of part 8 designed to receive end 2a and lead it on to the main part of the guide are described. The guides parts either side of the gap may be adjustable to ensure that the wire portions 2a, 2d do not foul each other.
