Title: Improvements in or relating to Telescopic and other Collapsible Towers or like Structures.
Inventor: BROUCKERE LEON GUSTAVE CHARLES
IPC: E04H12/18
Filed: 1916-03-02
Abstract: 104,388. Brouckere, L. G. C. L. de. March 2, 1916. Posts.-Relates to collapsible or telescopic masts, such as are used in wireless telegraphy, observation towers or plyons. Fig. 1 shows the sections formed triangular in section and of braced lattice girders. Each section, except the top one, is provided on each side with a hinged strut 1<a> consisting of bars t joined together at their outer ends, and all the struts in the same vertical plane are united together at their extremities, to the top of the uppermost section, and to the bottom of the lowermost section by ties f. The struts on the same horizontal plane may be connected together by ties h<1>. The outer end of each strut is also connected with the upper part of the section next above by a tie g<2>. With this arrangement, when the mast is fully extended, the ties and struts form trusses which strengthen the structure, and any section of the mast may be lowered without interfering with the rigidity of the part below it. The particular construction of each strut is shown in Figs. 2 and 4. For taking up slack in the ties f<2>, g<2> when the structure is collapsed, each tie is connected to the strut and also by hooks i and cords I to extensible cords or springs X which pass through the tubular bars t of the struts, over pulleys p and are secured with. in tube t<0> arranged parallel with the tubes t, so that when the structure is collapsed, the ties are drawn within the tubes t. The guys G', G<2>, G<3> by which the structure is maintained in a vertical position are so selected that the outer ones G<3> passing to the highest points of the structure axe less yielding than the guys G<2>, and these less yielding than the guys G<1>. The bottom section is mounted upon a universal joint U of any suitable type. The structure may be extended before it is erected or subsequently by means usual in structures of this kind.

Title: Improvements in or relating to furnaces
IPC: F23N3/02
Filed: 1925-02-06
Abstract: 228,924. Roucka, E. Feb. 7, 1924, [Convention date]. Air supply, regulating.-In a steam boiler furrace the air supply for combustion is regulated in accordance with the pressure in the fire-box, and variations in this pressure are utilized for varying the speed of the air supply fan by the operation of a switch arrangement which throws over, to a different voltage, the electromotor driving the fan. As shown, air is supplied to the firebox of the boiler 2 by a fan 8 in the outlet of which are arranged a hand-operated damper 12 and an automatically operated damper 10, the latter being connected through a weighted rope 68 with the piston 64 of a servo-motor 62. The valve gear of this motor is operated, through a rocking-lever 58, by a bell 54 in communication with the fire-box by means of a pipe 52. The piston 64 carries an arm 50 which, by engagement with one or other of the spring-supported stops 46, 48, moves the valve gear 40 of a second servo-motor 38, and consequently the piston 36, into one or other of the end positions. This movement of the piston 36 displaces the arm 32, which is pivoted on the same axis as a weighted lever 30 to which it is connected by a spring 34. The lever 30 is formed with projections 35, 37, each adapted to contact with one arm of a bell-crank 33 attached by a rod 28 to a 6-way switch 26. The latter, in the position shown, connects the stator 20 of the fan motor directly to the line circuit 22, the motor then running on full voltage; when, however, the switch 26 is moved by the piston 36, through the arm 32, lever 30, and bell-crank 33, the lead 22 is connected to a transformer 24 and the stator 20 with tappings 23 from the transformer, the stator being thus switched over to half voltage. More than two speed stages may be provided if desired. In small units reversing of the switch 26 may be directly obtained by means of the piston 64 or rope 68.

Title: Improvements in or relating to signal and like recording systems
IPC: H04N1/034
Filed: 1931-02-04
Abstract: 365,345. Recording sound. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Ranger, R. H. ; 574, Parker Street, Newark, New Jersey, U.S.A.) Feb. 4, 1931, No. 3566. Convention date, Feb. 4, 1930. [Class 40 (ii).] In a recording system for electric signals for the purpose, amongst others, of producing a sound film, a fluid jet which directly or indirectly effects the marking action is intermittently allowed to impinge on the record surface by the movement of an intercepting jet controlled by the signals and normally passing transversely of the recording jet. Alternatively, the recording jet may normally impinge on the record surface, and the intercepting jet may be deflected by the signals to prevent the jet of recording fiuid from reaching the record surface. Direct recording may be effected by a vapour jet of coloured ink, or alternatively, a. jet of hot air may be employed for thermal recording on a heat-sensitive recording surface. A jet of the vapour of a coloured ink is forced by a circulation system 41, 43, 45, 47 through a nozzle 9 in a path 11 through an aperture 91 normally traversed by a water jet 21 from an electrode nozzle 19 associated with a threaded polepiece in the circuit of a transformer, to the primary winding of which are applied the amplified signals. The jet 21 is controlled electrostatically or electromagnetically, and when deflected by the signals allows the jet of ink vapour to impinge on the record surface. In an arrangement, Fig. 4, for the production of a sound film the " blocking" " jet passes between control electrodes 59, 61 connected to the secondary winding of the transformer 27, to the middle point of which is connected a biasing battery 63 in series with the nozzle electrode 19. The ink jet 57 is of rectangular section and passes transversely of the " blocking jet " 21 of which the oscillations effected by the signals are recorded on the moving tape or film by a sinuous white line 65, the remaining parts 67, 69 being coloured by the ink jet. To provide a constant area sound record the " blocking jet " 21 is of rectangular section in the plane of the film 51 and of width equal to that of the recording ink-jet 57, the record being measured relative to either of the edges 69 or 71. Specification 303,809, [Class 40 (iii), Telegraphs, Electric], is referred to.
