Title: Improvements in or relating to temperature or fire alarm systems
IPC: G08B17/06
Filed: 1934-04-26
Abstract: 437,288. Electromagnetic and mercury switches. ETABLISSEMENTS MIGHOM, 29, Rue Celina Dubois, Montrouge, France. April 26, 1934, Nos. 12658, 12659, and 12660. Convention dates, April 28, 1933, Aug. 19, 1933, Feb. 3, 1934. [Class 38 (v)] [See also Group XXXVIII] A self interrupting switch 25 comprises a mercury chamber containing an electromagnetically-operated float 26. When the circuit through the mercury is interrupted the float drops and forces the mercury upwardly to complete the circuit at 28. The solenoid 30 is then energized to lift the float and break the circuit. These operations are repeated to cause intermittent operation. Fig. 5 shows means for ensuring positive engagement between the fixed and movably contacts of a galvanometer relay. The movable contact 91 is adapted when operated to pass between a fixed contact 92 and a spring-controlled pivoted contact 93 which is forced into co-operation with the contact 91 by an electromagnet 95 supplied with intermittent current. Fig. 6 also shows a gravity operated mercury switch 117 which is normally retained by a latch held in position by a pin 127 engaging the glass panel 128 of a fire alarm box. When in the case of fire &c., the panel is broken the latch is withdrawn by the spring 129 to allow the switch to rotate and remove the short-circuit across a resistance 131 included in a signalling circuit. Fig. 7 shows a similar switch adapted to be rotated to open the short-circuit across the resistance 131. When the switch is rotated the mercury falls into the chamber 136 and when released the mercury returns through the throttled channel 137 so as to prevent short-circuiting until after a predetermined delay.

Title: A process and contrivance for the treatment of water for the feeding of steam boilers and the like
IPC: C02F5/02
Filed: 1947-05-24
Abstract: 639,408. Purifying water. KOPECKY, F., and VONDRUSKA, F. May 24, 1947, No. 13998. [Class 46] In the treatment of water for feeding steam boilers and for removing silicic acid therefrom, clear saturated lime-water is prepared from the whole of the water and subsequently is saturated with carbonic acid gas or gas mixtures containing it, whereupon precipitated calcium carbonate is removed by sedimentation or filtration, the process being chiefly characterized in that saturation with carbonic acid gas occurs at 75‹ to 100‹ C., at which temperature the gas is insoluble in water, so that no calcium bicarbonate can form. Crude water entering by the pipe 1 is preheated at 2 and 4 to about 100‹ C., and passes to a vessel 5 where air escapes at 6, and milk of lime is introduced from a vessel 7. The water is then pumped tangentially into a reaction cone 8 having radial baffles 9, and becomes a clear saturated solution of calcium hydroxide, passing via a filter 11 to a saturator 13, where it is finely divided by a distributer 16 and iron shavings on sieves 17. Cleaned smoke gases containing carbon dioxide are introduced at 18, and hot steam at 19, the waste steam escaping at 32 serving to pre-heat the crude water. Calcium carbonate is formed in the saturator 13, and the now-turbid water passes into an equalizing vessel 21, and thence tangentially into a settling tank 23 consisting of two truncated cones 24, 25, the latter having radial baffles 33. The inner cone 24 becomes filled with sludge which acts as a filter, excess sludge flowing into the outer cone and being discharged at 28. The purified water is finally discharged through a filter 30 filled with marble or graphite pieces. Specification 639,460 is referred to.

Title: Improvements in separating crystals from mother liquors containing more than one salt
IPC: B01D9/02
Filed: 1918-08-13
Abstract: Crystals deposited from a solution containing more than one salt are freed from mother liquor in a centrifugal machine, the process being completed by treating the crystals immediately the bulk of the mother liquor has been removed with water in a state of fine subdivision, either as spray or wet steam, so that no dry air can enter the mass until all the mother liquor has been removed.  The crystals are preferably taken from the evaporator and treated at the temperature of their formation, the steam being introduced at a temperature suitable to bring about this result. A centrifugal machine, such as that described in Specification 119,706, which can discharge the crystals without stopping, is preferably used.  The process is described in connexion with freeing crystals of sodium carbonate from a liquid containing common salt.

Filed: 1938-05-04
Abstract: 514,401. Valve amplifying circuits ; television. BAIRD TELEVISION, Ltd., and NUTTALL, T. C. May 4, 1938, No. 13298. [Classes 40 (iii) and 40 (v)] The contrast range of a television or like signal is modified by varying the gain of an amplifier by controlling the negative feed-back so as to depend on the instantaneous value of the signal and to make the feed-back zero for a finite value of applied signal. The Figure shows a linear amplifier 1 the linearity of which may be increased by resistances 10, 12 and serves as a high impedance signal source. The anode circuit of the amplifier 1 is arranged in parallel with the anode circuit of a valve 4 having a non- linear characteristic and its grid fed from the output of the valve 1 in such a manner as to produce negative feed-back. As shown, the signal is amplified by the cathode follower 7 and the D.C. component is inserted by the diode 9 the amplitude of the D.C. component relative to that of the A.C. component being determined by the ratio of resistances 13, 14. Resistance 16 and condenser 3 remove the saw-tooth error in the D.C. component. Numerical data are given in an example and the valve 4 may have a parabolic or an exponential characteristic and give a reduction in contrast particularly when transmission is from a photographic film.

IPC: B64C29/00
Filed: 1961-04-13
Abstract: 943,626. Jet propulsion plant; axial-flow fans. ROLLS-ROYCE Ltd. April 6, 1962 [April 13, 1961], No. 13407/61. Headings F1C and FIJ. In a gas turbine plant fan rotor blades are mounted in a duct and driven by the turbine, thrust control means being provided for preventing the fan rotor blades from doing useful work or for reducing the work done by the blades, the thrust control means comprising movable inlet guide vanes for the fan. A ram 36 is connected by a rod 37 and a bell crank lever 38 (Fig. 2 not shown) to an inlet guide vane and all the vanes are connected together for simultaneous movement. Air bled from the compressor of the gas turbine is led to a valve 40 via a pipe 62, and on starting, the air pressure acting on a valve member 42 is insufficient to overcome a spring 53, so that the latter maintains the member 42 in a position connecting the ports 56, 54, latter port communicating with the atmosphere. A port 57 communicates with the compressed air through a passage 50 and drillings 51 in the member 42 and the air acts on the ram piston 35 to move the inlet guide vanes to a closed position. As the compressor delivery pressure rises, the valve member 42 moves to the position shown and the compressed air passes through a pipe 60 to move the piston 35 so as to open the inlet guide vanes. In the alternative embodiment shown in Fig. 4, there is provision for an additional manual control of the inlet guide vanes 32. When the gas turbine is started, the guide vanes 32 are in the closed position shown in dotted lines. Air from the compressor is led to a cylinder 85 via a pipe 62<SP>1</SP> and as the turbine speed increases it overcomes a spring 87 to move a piston 84. The piston is connected to a valve member 73 which member moves to bring a passage 74 into communication with a high pressure oil or fuel supply in a pipe 77 to act on a stationary piston 67. The vane operating ram 66 then moves to the full line position shown. A rod 92 is connected to an aircraft auto-stabilizer which allows for differential operation of a plurality of gas turbines in response to changes of flight attitude of the aircraft. A rod 93 is connected to a common control for simultaneous operation of the gas turbines. The piston 84 and cylinder 85 may be replaced by a centrifugal mechanism moving the member 73 against the action of a spring, or the mechanism may be directly connected to the vanes 32. The vanes may also be connected to the pilot's fuel throttle lever to overcome any inertia lag when the turbine fuel supply is suddenly altered.
