Patent GB-679364-A (GB)
Title: Improvements in or relating to thermally operated devices
IPC: G09F19/00
Filed: 1948-07-05
Abstract: 679,364. Thermal motors. TIGRETT, J. B. July 5, 1948, No. 18007/48. Class 69 (i). A thermally operated device comprises a bracket, a housing pivotally mounted on the bracket, a hollow member containing some volatile liquid in relative hot and cold connected chambers in the housing, a heating element to heat the hot chamber which is located lower than the cold chamber, and one or more sounding members pivotally mounted within the housing engaging with the housing wall when the housing pivots due to some of the liquid on being heated moving from the hot chamber into the cold chamber. As shown a housing 12 is pivotally supported on a bracket 20 and contains a member 14 which is secured to the housing by a bracket 16 and a projection 18. A pair of sounding members 24 swing freely on the bracket 16. The member 14 contains two chambers 26, 28 which are connected by a tube 30 which extends nearly to the bottom of the lower chamber 28. A lamp 34 mounted on the bracket 20 heats a volatile fluid in the lower chamber 28 and the resulting vapour pressure causes some of the fluid to migrate to chamber 26 which eventually overbalances together with the housing 12 until the lower end of the pipe 30 is clear of the remaining fluid in chamber 28 ; this allows the vapour to flow to the upper chamber to equalize the pressure and to become condensed in the relatively cool upper chamber. Fluid in the upper chamber can also then return to the lower chamber and so restore the housing to its initial position. During the pivoting of the housing the sounding members strike the housing or smaller bells within it. The interior of the housing may have a light reflecting surface and openings in its upper portion.

Abstract: 375,544. Loose-leaf binders. WELLS, G. N. and WELLS & CO., Ltd., G., 42, Southwark Street, London. June 22, 1931, No. 18046. [Class 146 (i).] In loose-leaf binders of the type having filing-posts terminating in a rotatable transverse abutment for locking engagement in apertured parts, the abutments are permanently attached to the posts so that the post and its abutment form a single unit, for co-operation with an apertured plate. The metal post 1, Fig. 1, is provided with a substantially T- shaped head 7 adapted to be inserted in an apertured plate 8 which is secured to the cover 4 of the binder. The cover 4 is folded to provide two folded parts 10, 10a which are stitched or riveted at 11. The baseplate 2 of each post is held between the fold of the part 10, and the apertured plate 8 is provided with prongs 12 which are passed through one or both parts of the fold 10a and bent over. The baseplate 2 may be integral with the post 1, or may be riveted to a reduced-diameter extension of the post, and may be formed with an arcuate or channel sectioned periphery in order to avoid exposed sharp edges and provide rigidity. The baseplate 2 may be formed with prongs to secure it to the fold 10a and in this case the post 1 is rotatable relatively to it. In a modification the head 7, Fig. 7, is rotatable relatively to the post 1, and the post is formed of rubber, leather, flexible tube, elastic, or a length of coiled wire similar to a length of Bowden wire outer casing. The head 7 is formed with a reduced-diameter portion which passes through and is riveted to a metal cap 17 fixed to the top of the post by means such as punched depressions 19. The lower end of the post is fitted with a similar cap 18 having a head 20 which is secured to the baseplate 2. If desired, the head 7 may be fixed to the post 1 and the head 20 arranged to rotate in the baseplate 2. Instead of employing one apertured plate 8 for each post, a metal &c. strip having apertures for all the posts may be provided ; also the baseplates 2 of the posts may be replaced by a single metal strip.'

Abstract: 700,531. Heating liquids by direct contact with steam. FAIRLEY, T. May 21, 1952 [July 31, 1951], No, 18106/51. Class 64(1) A steamheated immersion heater for water and other liquids comprises a chamber 1 provided with an inlet 5 for steam under pressure, means for directing cooling water i n t o contact with the steam in the chamber 1, and a steam outlet remote from the inlet and consisting of a plurality of small apertures 14. The volume of the chamber is such as to allow the steam to expand and so become superheated, and the amount 'of cooling water reaching the steam is such as to reduce or eliminate the superheat, so that the steam entering the liquid to be heated is saturated steam. Steam from a constricted inlet 5 flows through a cylindrical chamber 1 projecting into a tank containing the liquid to be heated, and draws liquid through openings 13 near the top of a central pipe 11 open at the bottom to the liquid in the tank. The steam passes from the chamber 1 into the main body of liquid through slots 14 in the corrugated lower part of the cylindrical wall of the chamber 1. When the liquid has reached a temperature of say 140‹F, liquid is supplied under manual or thermostatic control from an external source through a pipe 10 and an annular recess in the cover plate 4. In a modification the lower part of the cylindrical wall instead of being corrugated is provided on the inside with vertical channels closed at the top and open at the bottom to liquid in the tank.

Abstract: 421,652. Valve modulating circuits ; thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and LADNER, A. W., Goonhilly, Danbury, Essex. June 28, 1933, No. 18427. [Classes 39 (i) and 40 (v)] Modulation of a magnetron oscillator is effected by simultaneous control of the anode voltage and the magnetization field. As shown in Fig. 2, the split anodes 2, 3 are connected to opposite sides of a tuned circuit which has its mid-point connected through a high-tension source 7, 8 to the cathode 11. The anode circuit also includes the field coil 6a, and a modulating-choke 6b, and the modulating- voltage 10 is applied to the grid of a triode 9 which has its plate connected to a point between the coils 6a, 6b. The coil 6a may be omitted, and the choke 6b utilized as the field coil ; or the choke 6b may be transformer coupled to the field coil. In Fig. 5, series modulation is employed, and, the field coil 6d is in series with the discharge paths both of the magnetron 1 and of modulating triode 9 ; or the field coil may be energized by the secondary of a transformer, the primary of which is in series with the elements 1, 9. In another arrangement, the modulating voltage is applied to a primary coil, and the secondary coil constitutes the field coil of the magnetron. A polarizing field coil 12 separate from the modulating coil is preferably employed. The field magnet may have an open rectangular core 13, Fig. 3, with inwardly-projecting poles 15, 16 between which the magnetron 1 is placed. The polarizing coil 12 and modulating coil 6a surround the respective poles. In the magnetron shown in Fig. 8, the glass envelope 16 is sealed to knife-edge extensions on end-caps 17, 18 of magnetic material preferably nickel-iron between which the filament 19 is supported. The leads to the anodes 20 are taken through the sides of the glass envelope. The end-caps may be recessed as shown to correspond to the shape of the pole-pieces 21, 22 of the magnet. Alternatively, the end-caps and the polepieces may be flat and separated by insulation (Fig. 7 not shown). In another modification, an envelope having the usual re-entrant foot may be used, and two blocks of magnetic material may be supported inside the valve close to the walls with the filament stretched between them. The blocks thus form extensions of the polepieces of the external magnet. Specifications 397,036 and 399,579 are referred to.
