Abstract: 1,165,359. Supporting vapour generators; tube walls. COMBUSTION ENG. Inc. 7 Dec., 1966 [20 Dec., 1965], No. 54872/66. Headings F4A and F4B. A once through or forced recirculation supercritical vapour generator has its furnace walls lined with tangent or finned tubes 40, backed by furnace insulation 42 and horizontally extending stiffener members 44 all supported by the furnace tubes. A cage of vertically extending I beams 50 supported independently of the furnace walls from structural steel work 46, surrounds the furnace walls in sliding contact with the stiffener members 44, which I-beams 50 are inter-connected at several horizontal levels by buckstays, such as 58, 60, 62, 64 extending along the furnace walls and welded to the vertical I beams 50. Opposed buckstays e.g. 58 and 60, or 62 and 64 are inter-connected at their ends by fluid carrying members 80 and 82, or 76 and 78, which pass through holes in the vertical I beams 50, in such a way as to allow for expansion and contraction on heating and cooling of the furnace walls. Thus each buckstay e.g. 58 is secured to its respective fluid carrying member e.g. 80 by a pair of rods 84 which pass through openings 85 in the buckstay, and openings in a collar 86 secured to the fluid carrying member. Rockers 88 and nuts 90 are then threaded on to the ends of the rods 84. The fluid carrying members 76, 78, 80 and 82 form part of downcomer circuit, in parallel with main downcomer 22 extending between the upper outlet headers of the tubes of a furnace division wall 20, and lower inlet headers of the furnace wall tubes 40. In this way the expansion of the fluid carrying members on heating is kept at the same order as that of the tube walls.

Title: A control system comprising a low-pass filter for variable frequency fluid signals
IPC: F15C1/02
Filed: 1964-07-06
Abstract: 1,078,533. Fluid regulation. BOWLES ENGINEERING CORPORATION. July 6, 1964 [July 5, 1963], No. 55766/66. Divided out of 1, 078, 531. Heading G3H. [Also in Division F1] A fluid control system includes a low pass filter comprising two parallel tapered passages 31, 32, Fig. 1 (not shown) connected by a series of narrow cross-over passages (33) in the form of a ladder. The parallel passages taper to a size equal to the cross-over passages and the wider end constitute the inlet and outlet of the filter. A pulsed fluid flow is fed through the filter and at low frequencies the pressure drop in the cross-over passages is small and the flow is passed through the filter. At high frequencies the cross-over passage effect a large pressure drop and then the high frequency signals are greatly attenuated. The tapering of the inlet passage minimizes reflections of the high frequencies. This RL ladder arrangement also acts as a sonic filter in that a single narrow passage while filtering the high frequency pressure signals rings at frequencies above the tuned frequency and the cross-over channels are effective to break up the wave front as the signal passes between the tapered passages. The filter may also include a capacitance thus forming an RLC filter. The filter is used in the control system described in Specification 1, 078, 531.
Patent GB-557776-A (GB)
Abstract: 557,776. Totalisators. SMITH, A. M. Oct. 31, 1941,.No. 14036. Convention date, Nov. 1, 1940, [Class 40 (i)] [Also in Group XL] The adding apparatus in an electric totalisator is provided with two pairs of thermionic valves each of which transmits one impulse for every two received, the whole arrangement sending one impulse to the recording apparatus for every four received. Valve circuit.-As shown in Fig. 1 a pair of gas-filled tubes 1, 2 have their grids energized in parallel and their anodes fed through separate resistances 6, 9. The circuit is prepared by temporarily removing the bias from the grid of tube 2 which thereupon passes current. When now an impulse is received, both grids are raised in potential beyond the point necessary to initiate a discharge and tube 1 thus becomes conducting. Owing to the resulting sudden reduction in the voltage of point 10, an impulse is given via condenser 7 in such a direction as to stop the discharge in 2. The resulting rise in voltage at the anode of 2 causes a discharge in a neon indicator lamp 8. The next impulse in a similar way restarts the discharge in 2 and stops it in 1 and an impulse is thus given to the upper tube 3 of a similar pair which thereupon breaks down and stops a previously existing discharge in the lower tube 4 causing a lamp 12 to glow. The third impulse operates in the same way as the first and the fourth operates on the first pair in the same way as the second. In the second pair. however, the discharge in 3 is stopped and that in 4 is restarted extinguishing 12 and operating a relay 13. When the 10/- machine 16, Fig. 3, is connected up, a ticket is issued and a circuit is made over a "Win" and "Place" switch 36, for (say) the "Win" adding unit ofhorse No. 1 and the "Win" grand total unit 39. When the horse unit has had four impulses it energizes 41 which sends an impulse timed by 48 with the help of a condenser 50 to units magnet 24. Similarly relays 48b, 48a co-operate to control the grand total "Win" counter. ú1 machines receive two impulses from the distributor and relays 54, 56 controlling the tens counters are operated directly via ú5 machines such as 66. When a units recorder has made ten steps it energizes 70 to operate the tens magnet 30. To avoid interference between this circuit and that controlled by the ú5 machines, operation of one circuit opens the other, any intervening signal being held by condensers 63, 65. Counting apparatus.-The units drum, Figs. 4 and 5 is controlled by an escapement activated by a magnet 24 and any particular digit appears several times in one rotation. The tens and higher value drums give one step at each rotation to the next drum by means of a two step cam 74 on the drum of lower value which reciprocates a slide 76 carrying driving and check pawls 77, 78.

[Also in Division H4] In a system for identifying moving objects e.g. railway wagons or other vehicles, the interrogation transmitter radiates two frequencies and the transponder carried by the moving object includes a non-linear element and a circuit tuned to the difference of the two frequencies, the difference frequency being reradiated to a receiver. As shown in Fig 1 transmitters 1, 2 radiate frequencies f1, f2 via radiators 5, 6, provided with reflectors 7, 8, the radiated beams 9, 10 being arranged to converge at 12 on a slotted waveguide 16 carried by the movable object. The slots provide a code identification signal as the object moves past the transmitter. A non-linear element 19, e.g. an ordinary rectifier diode, a varactor, an avalanche diode, a tunnel diode or a ferromagnetic element causes the frequencies to beat, and the difference frequency f1-f2 is selected by a tuned circuit 20 and re-transmitted via an aerial 21 to a receiver 23. Instead of using a pair of radiators 5, 6, the transmitters 1, 2 may feed a single radiator via a hybrid circuit. Alternatively a wave of frequency f1 may be modulated by a low frequency corresponding to f1-f2, the low frequency being detected by the element 19 and re-radiated. If the object is fixed, deflection means may be provided to scan the beam across the object, Fig. 6 (not shown). In a further embodiment, Fig. 7, the transponder consists of a plurality of spaced receivers, each consisting of an aerial 72 &c., coil 71a &c. and a non-linear element 79a &c., with co-operating tuned circuits 70a &c. feeding the transmitting aerial 21.
