Title: Improvements in or relating to electro-magnetic control arrangements
IPC: H01H47/00
Filed: 1920-01-30
Abstract: 138,867. Maier, C. Feb. 8, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Electric operation. - Relates to electro - magnetic actuation of electric switches, railway points, or other apparatus. For this purpose, two electro-magnets are employed with a control switch connected to one terminal of each magnet winding, the other terminals being connected direct to the mains. Fig. 1 shows one arrange. ment. The electric switch or other apparatus to be actuated, which is not shown, is moved by a lever 2, attached to cores 3, 4 of solenoids B, C. The upper terminals of the solenoids are respectively connected to the mains G, H. The lower terminals are connected through auxiliary switches D, E, of which one is necessarily closed and the other open, to a wire J leading to the control switch F. This is shown diagrammatically as consisting of a movable bridging-contact 11 and two pairs of stationary contacts 12, 13, 14, 15 adapted to be bridged alternately. Pivoted detents 5, 6 keep the auxiliary switch member 9 in position until the descending solenoid has nearly completed its movement, when the switch member is released and rapidly thrown over by springs 7, 8. In a modified arrangement shown in Fig. 2, an additional control switch L actuated from a distant point by means of an electro-magnet K supersedes the hand control switch F whenever required. Signal lamps W, R indicate whether the main switch is on or off. In a further modification, the indicating lamps are connected so that they light up only when the position of the main switch does not agree with the position of the control switch F.

In a first embodiment the hinge between each stick section comprises two parts 5, 6 formed to receive an end of respective stick sections, the part 5 being provided with a lug 7 having a hook 10 which when the stick sections are aligned engages under a hook 12 carried by a wall member connecting a pair of lateral lugs 11 of the hinge part 6. The lug 7 is formed with an elongate slot 8 which receives a pin 13 extending between the lugs 11, a spring 9 acting between the pin and one end of the slot and serving to bias the hooks 10 and 12 into engagement when the stick sections are aligned. The hinge is such that when the stick is collapsed as shown in Fig. 8 a space to receive part of the frame is provided between the stick sections. In a further embodiment, Figs. 9 and 10, the hinge comprises circular members 16, 17 connected by a pivot pin 18 and each provided with a socket 14, 15 respectively to receive a stick section. A spring 19 on pin 18 biases the members 16, 17 together and member 17 is formed with diametrically opposed apertures 21 which receive studs 20 carried-by member 16 in the collapsed condition shown and in the aligned position of the stick sections.

Damage arising from excessive pressure applied to the diaphragm 9 Fig. 1, of a pressure transducer consisting of an inductive sensor 1, 2, 3 in a casing 4 with a non-ferromagnetic end portion 5, is prevented by a dish-shaped surface on the side of the casing portion 5 facing the diaphragm 9. The dish-shape has the same contour as is assumed by the diaphragm under a predetermined maximum stress, so that it supports the diaphragm when pressures in excess of the maximum are applied. The sensor comprises a coil 2 on a former 3 with an axial bundle of wires 1 constituting the case, the ends of the wires being bent back over the outside of the former 3 so that both sets of wire ends are coplanar adjacent the casing portion 5. The portion 5 of the casing may be detachable (4a), Fig. 2, (not shown). The sensor is fixed in place by an adhesive; and the diaphragm (21), or at least that portion 5 of the casing which may constitute the diaphragm, is of stainless steel aluminium, brass, copper, or other non-ferromagnetic metal, or of plastics or other insulating material. The space between the diaphragm 9 and the portion 5 may be evacuated to give an absolute pressure transducer.

Filed: 1931-01-31
Abstract: 371,943. Tea withering. MAIN, J. A., Clydesdale Ironworks, Possilpark, Glasgow. Jan. 31, 1931, No. 3162. [Class 34 (ii).] In a controlled tea-withering process, air is passed through the enclosure containing the leaf racks and periodically over heat-exchanging means in order to maintain it within the limits of temperature and humidity demanded by the condition of the leaf. Withering is carried out at a temperature of about 60-80‹ F. As shown in Figs. 1 and 2, apparatus for carrying out the process comprises a chamber with trays or shelves 2 facing the airtight doors 3. The shelves 2 may be pivoted to a partition disposed longitudinally in the centre of the chamber and may be withdrawn or tilted when the doors are opened or removed. Air enters through a duct 5 and strikes the first set of transverse heating or - cooling coils 6 and after passing over a tray containing tea passes in contact with another set of coils. The'air thus passes alternately in contact with the heat-exchanging devices and with a section of the leaf racks. If a reversible air current is to be employed, a set of heating or cooling coils is placed adjacent to the outlet duct 7. As shown in Fig. 4, the leaf racks 8 are enclosed in a number of chambers connected in series by ducts 10 in which the heating or cooling coils 11 are placed.

Abstract: 683,359. High-frequency transmission lines. STANDARD TELEPHONES & CABLES, Ltd. Feb. 9, 1951 [April 1, 1950], No. 3195/51. Class 40 (viii). In a micro-wave transmission system in which energy is propagated by waves closely surrounding a single insulated conductor 1, the latter is held in position by dielectric means extending from a support for a sufficient distance to maintain the latter outside the concentrated magnetic field around the conductor 1. The construction in Fig. 1 shows an end support 2 and an intermediate support 3 for conductor 1. The support 2 has a flared end 4 and a matching stub 5 at the other end and has an input or output wave-guide 12 coupled thereto. Dielectric means 8 support the conductor 1 within the horn. The tapering of the ends of means 8 and the flaring of end 4 prevent undue perturbation of the wave energy passing the support. The middle support 3 is flared at each end and contains tapered dielectric means 20. In an alternative construction the passage through the dielectric means may be flared out at the ends to produce a similar effect to the tapering. In a modification, the dielectric means comprise threads 45 looped around conductor 1 and secured to a support-ring 43 surrounding the conductor. Further a channel may be formed for conductor 1 in a dielectric slab 59 which is provided with an aperture so that it can be hung on a hook. In the construction shown the channel is curved.
