Title: Improvements in thermally-operated electric switches
IPC: H01H37/66
Filed: 1934-05-26
Abstract: 437,826. Thermal and magnetic switches. SANDERS, H. C., Somerton Works, Newport, Monmouthshire. May 26, 1934, No. 15718. [Class 38 (v)] A thermally. operated switch has a plurality of switch members which have armatures mounted on the ends of flexible contact-carrying members, a plural. ity of magnets for returning the armatures to close the circuits and an adjustable member which is set in relation to the flexible contact-carrying members to regulate the temperatures at which said switch members cutout. Asshown in Figs. 1 and 2 a rod 5 and sleeve 4 having different coefficients of expansion is adapted to operate two flexible switch arms 7, 8 the anchored ends 9, 10 of which are connected to a common terminal 11. The free ends of the arms 7, 8 are provided with armatures 13, 14 disposed below the poles of permanent magnets 17, 18 contacts 15, 16 on the armatures being adapted to project, as shown in Fig. 4, upwardly between the poles of the permanent magnets into engagement with adjustable fixed contacts 21, 22, carried by bent-over arms 19, 20. Where the flexible switch arms are engaged by the flanged edge of an insulating washer 24 on the rod 5 they are kinked as at 25. The position of this operating projection may be adjusted by a screwed thimble 23 working on the threaded'upper portion of the rod 5, which thus forms a common adjusting means to regulate the temperatures at which the two switch members cut out, each member being also independently adjustable by movement of its relatively fixed contact 21 or 22. The magnets and their co-operating armatures ensure a rapid breaking action of the switch arms. The two contact arms may thus be arranged to control the different circuits at different operating temperatures.

Abstract: 806,293. Ion-trapping in cathode ray tubes. STANDARD TELEPHONES & CABLES Ltd. May 25, 1956 [May 26, 1955], No. 16254/56 Class 39(1). In a cathode ray tube with an ion trap gun the ion trapping magnetic field is produced by one or more permanent magnets arranged in or behind the plane of the cathode and within the tube. In one form, Fig. 1, two permanent magnets 5 of Al-Ni or Al-Ni Co (preferably sintered in vacuum) are held by clips 4 at least partly of ferromagnetic material, e.g. Ni or Fe, welded to the control electrode 2. A transverse electric field is generated by known means to deflect the total beam and the magnet redirects the electrons on to the axis. The permanent magnets are preferably held in notches in clips 4 and the magnet poles of the two permanent magnets point in the same direction. Alternatively a permanent ring magnet magnetised in the plane of the ring, can be used. In the preferred form, Fig. 2, a single permanent magnet 5 is arranged closely behind the cathode. The magnetic field encountered by the electrons is thus short.

Filed: 1926-06-29
Abstract: 272,693. Highfield, J. S., and Highfield, W. E. June 29, 1926. Feedwater, suppl.ying and control. ling.-Relates to apparatus for providing feedwater for steam boiler plants, and to the storing of a de-aerated supply of feedwater therein. According to the invention a closed storage tank 39 for de-aerated hot water is maintained at such a pressure that when the supply of water is in excess of the load requirement the excess goes to the tank but when deficient the tank augments the supply. Steam from the boilers is supplied to a turbine 1 and exhausts to a condenser 2, in which the vacuum is maintained by ejectors 3, 4. The de-aerated concentrate passes by the non-return valve 7 to an exchanger 8 of the surface condenser type. Feed water is supplied to the boilers by a pump 11 from the exchanger 8. The vacuum in the exchanger is regulated through a reducing valve 15. A raw water tank 16 is connected to the evaporator 19. Steam from the ejectors 3, 4 is supplied to the coil 20 in the tank 16 and the cohdensate is led to a tank 22 having an air vent 23. The coil 24 is supplied from the feed pump 11 and discharges into the exchanger 8 while the coil 26 is fed with low pressure steam from the turbine 1 and also discharges into the exchanger. Regulating valves 31, 32 control the supply of steam or water to the perforated pipe 12 in the exchanger. The drain tank 22 receives the discharge from all the steam traps &c., and the hot water is led back to the pipe 12, when sufficient has collected to operate the ball valve 35. The pipe 12 is heated by vapour from the evaporator 19 and the water therein is projected in spray through perforations 13 whence it falls over the pipes 9 and is deaerated. The condensate collects in a well 36 and is pumped to the storage tank 39. The tank 89 is maintained at a constant pressure by steam from the pipe 41 which passes a reducing valve 42 at about 10 lbs. per sq. inch. The upper part of the tank 39 is reduced in area to minimize condensation. Two float valves 46, 47 are provided in the pipe 17 leading from the raw water tank 16, the valve 46 cutting off the supply when the water in the tank 39 reaches a predetermined level while the valve 47 only opens when the water sinks to another predetermined level, to admit raw water when the level is dangerously low. The feed pump 11 pumps the feed water to the boilers through the pipe 49 and two further heating coils 51, 53 may be included in this pipe line. Modifications in which the means for maintaining the vacuum in the exchanger 8 and in which the condensate from the well 36 is discharged into the suction side of the pump 6 are shown and described.

Abstract: 831,785. Counting and sizing particles. RANK CINTEL Ltd. May 27, 1957 [May 28, 1956], No. 16425/56. Class 40 (3). In an apparatus for counting and sizing particles in a sample by line-by-line scanning the total number of particles is recorded by a counter 6 which receives a signal when a particle is intercepted for the first time, and the numbers of particles in different size groups are recorded by counters 61, 62, 63, &c. which receive signals when particles are intercepted for the last time at different numbers of lines from the first interceptions. Signals from a scanner 1 are passed direct and through a oneline delay system 2 to a trigger circuit 3 and thence through a delay circuit 4 to a gate 5 which is opened to allow a signal from the delay system 2 which has been differentiated and applied to a polarity-conscious circuit to pass through to the counter 6. The counter 61 is provided with an anti-coincidence gate 51 to which signals are applied from the trigger circuit 3 through a one-line delay 21 and from the scanner 1 through a trigger circuit 31, oneline delay systems 22 and delay circuit 41. If both signals are present, the anti-coincidence gate 51 remains closed, but if the second signal is absent due to the last interception of the particle having been reached, the gate is opened to allow a differentiated signal from the gate 5 to pass through to the counter 61. Similar circuit arrangements are provided for the counters 62, 63, &c.
