Inventor: HEATH HERBERT HENRY
IPC: F23D11/10
Filed: 1950-10-09
Abstract: 702,215. Spray-producers. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Oct. 1, 1951 [Oct. 9, 1950], No. 24640/50. Class 69 (3). [Also in Group XI] A liquid fuel burner, particularly for viscous fuel, wherein the fuel is atomized by a stream of air, steam, or other gaseous fuel, comprises a body 1, Fig. 1, formed with an internal longitudinal bore 4 terminating in an orifice 5 in an end face of the body 1, a casing 2 surrounding the body 1 and including a wall extending across and spaced from said end face and having an orifice 6 aligned with the bore 4 to form together an atomizing gas blast passage, said end face and wall defining a transversely extending annular gap around the gas blast passage for leading fuel thereinto to be atomized, and the body 1 and casing 2 being formed with transversely extending locating faces facing and in fixed relationship to each other whereby the width of the gap 11 is positively determined. The locating faces may comprise as shown an end surface of the casing 2 and a surface of an end flange on the body 1, and spacing shims 20 may be introduced therebetween. The atomizing fluid is swirled within the bore 4 by a swirl plug 9 which has a perforated head for the passage of atomizing fluid, supplied through a union 8 screwed into the body 1, and is held against a shoulder within the latter by a spring 10. The casing 2 has a fuel inlet 12. In an alternative construction the swirl plug 9 is replaced by a thin pintle mounted similarly to the plug and having a conical diverging head extending beyond the discharge outlet so as to assist in forming a conical spray. Either construction may be modified by providing the orifice 11 between two parallel conical surfaces so that the fuel flows obliquely downstream into the atomizing fluid blast. Alternatively the end of the body 1 may have a slightly conical recess and the inner surface of the casing 2 a corresponding raised cone formation. The orifice 11 may also be convergent. In another construction the body 1 is not screwed into the casing 2 but is retained in position by a lock-nut, whilst the swirler 9 is held in position by means of sleeves within the body 1. The outlet end of the body is conically tapered and the casing 2 recessed to a lesser extent to form an inwardly tapering fuel passage, the width of which is adjustable by the interposition of a ring and, if necessary, of shims between a perforated flange on the tube and a shoulder at the end of the casing 2. In a further construction the body 1 is formed with external radial ribs which locate it within the casing 2, the swirler 9 being screwed into the body 1. According to the Provisional Specification either the fuel stream or the atomizing jet or both may be swirled.

Title: Improvements in or relating to diagnostic x-ray apparatus
IPC: H05G1/38
Filed: 1960-07-15
Abstract: 931,720. Control circuits for X-ray apparatus. SIEMENS-REINIGER-WERKE A.G. July 15, 1960 [July 17, 1959], No. 24770/60. Class 38 (4). X-ray diagnostic apparatus is arranged to be controlled so that the exposure is terminated either by an exposure device or by means which are responsive to the product of the current taken by the X-ray tube and the time for which this current flows. An X-ray tube 1 is supplied by way of a tapped transformer 6 and a high-tension transformer 2a, 2b together with a filament heating transformer 3. A control knob 4 moves a tapping 5 to adjust the H.T. voltage and at the same time causes a control device 9 to adjust the X-ray tube current to ensure that the tube loading does not exceed a permissible limit. The device 9 is also operative to reduce the X-ray tube current in stepwise manner from the set value during the subsequent exposure. A second control knob 13 controls a variable resistor 27 whereby the time quantity of a product of time and X-ray tube current is varied and also controls a change-over switch 16 which assumes the position shown when the knob 13 is moved to place the pointer 14 at the end of a scale 15. Exposure is initiated by a control device 10 which energizes a relay 12 to close contact 11. With the change-over switch 16 in the position shown the exposure is ascertained by an exposure device 19, after a sufficient exposure, closes contact 22 whereby relay 23 is energized to open contact 24 to remove the supply. Movement of the control knob 13 to alter the position of the pointer 14 causes switch 16 to change over and moves the setting of the variable resistor 27 to give a desired time-tube current product. The exposure is initiated as before by closing contact 11 which simultaneously begins charging of a capacitor 26, until it acquires a certain charge when gas-filled valve 28 ignites thus energizing relay 29 to close contact 30 whereby relay 23 is energized to remove the supply as before. An indicator lamp 17 indicates whether the apparatus is set up to be controlled by the exposure device 19 or the time-tube current product device 26, 27.

Title: Bandwidth control
IPC: H04B10/29
Filed: 1974-06-06
Abstract: 1465329 Optical communications system POST OFFICE 6 June 1974 25166/74 Heading G1A The bandwidth of an optical communications system is controlled by means of a section of liquid filled dielectric optical waveguide 8, silicon tube filled with carbon tetrachloride, disposed in a temperature maintaining device 9. The temperature of the waveguide determines the number of transmission modes allowed. The temperature is retro-actively controlled with respect to a comparison between the ratio of two pre-selected modes on the received bandwidth and a predetermined reference signal. The optical communications signal uses an optical carrier signal into which an analogue signal having a bandwidth to be controlled, is modulated. In a repeater circuit, Fig. 2, the light signal enters the system via the optical waveguide 7, passes via a section 8 of a liquid cored dielectric optical waveguide and is received by a photodiode detector. The detectors output is amplified and is passed to two tuned circuits 13, 14 which are tuned to a frequency W 2  corresponding to the half power point of the cut-off edge of the required bandwidth and a frequency w 1  corresponding to the flat response region of the desired bandwidth. The levels L 1 , L 2  of the frequencies W 1 , W 2  are measured by level detectors 15 and 16 and the results are passed to a divider 17 which produces a signal representative of L 1 /L 2  that is fed to an analogue comparator 18. There it is compared with  a reference signal, corresponding to the desired ratio value. The resulting error signal from the comparator 18 is used to reset the temperature of the oven 9 via a temperature reset unit 20 and a servo temperature controller 21. The repeater circuit also comprises a driver circuit 22, connected as shown, which powers and modulates a laser source 23 which is optically connected to an output dielectric waveguide 26. The number of modes excluded by this arrangement is determined by a second oven 25, operating at a pre-set temperature, enclosing a section of liquid cored dielectric waveguide. An arrangement involving a series of repeater circuits is also disclosed.

Title: Temperature or pressure control apparatus
IPC: G05D23/275
Filed: 1933-09-14
Abstract: 428,854. Thermal switches for boilers and refrigerators. HALL, W., 53, Shirehall Park, Hendon, London. Sept. 14, 1933, No. 25451. [Class 38 (v)] Apparatus for controlling temperature or pressure in a number of separate boilers or refrigerators comprises a common device such as a mercury switch f governing the temperature or pressure changing means for all the compartments and a number of temperature- or pressure-sensitive elements each in contact with a separate boiler or refrigerator and each capable of independently actuating the switch. The invention is shown applied to the temperature control of a battery of boilers, and into each boiler space extends a bulb b which communicates by a tube a with a diaphragm chamber (not shown). The bulbs contain a medium such as ether and each diaphragm is adapted to raise a rod d a projection a on which engages a common rod e mounted on ears q, pivoted to brackets r. The rod e carries a strip m which is connected to a rod n which actuates the switch f which controls a circuit of a fan, supplying air to the furnaces. Each rod d is guided in a sleeve g on a common plate h, the central sleeve g having screw-threaded engagement with the plate so that rotation of the sleeve raises or lowers the plate, and springs l are arranged between the plate and adjustable collars k on each rod d. The springs oppose the upward movement of the diaphragms, and their strength may therefore be adjusted individually or in common by adjustment of the collars k or plate h.
