Title: Improvements in and relating to heat sensitive devices for controlling valves, switches or other members
IPC: G05D23/08
Filed: 1935-10-08
Abstract: 448,316. Thermostats. JUNKERS & CO., GES., 35, Junkersstrasse, Dessau, Anhalt, Germany. Oct. 8, 1935, No. 27761. Convention date, Oct. 9, 1934. [Class 64 (ii)] [See also Group XXIX] A heat - sensitive actuating device comprises two bimetallic strips connected together which expand in opposite directions on heating. In Fig. 1, a gas burner 12 is supplied from a pipe 10 controlled by a valve 13 which is actuated by two bimetallic bows 17, 18 connected end to end as shown. The bow 17 is heated by a byepass flame 23, so that the valve 13 is closed when the byepass is extinguished. When the byepass is lit, the bow 17 operates rapidly to open the valve, its stroke being considerably greater than the valve lift. Heat is transmitted to the bow 18 which opposes the movement of the bow 17 and counteracts the excess of stroke of the bow 17 so that the valve does not exceed its normal lift. If the flame 23 is extinguished, the bow 17 moves to close the valve, but its excess of stroke is counteracted by the bow 18. Only the first part of the stroke of the bow 17 is used for control purposes, and lost motion is avoided. The bow 18 may be surrounded by a casing 42 to delay cooling, and the connection between the two bows may have low heat conductivity. The valve 26 is actuated by pressure-differences in the water pipe 27. In a modification, Fig. 3, the two bimetallic bows 34, 35, are arranged so that the bend in one is inside that of the other. In the Specification as open to inspection under Sect. 91, is shown a modification in which the valve is carried by a rod within a sleeve which has a higher coefficient of linear expansion and is subject to the heat of the pilot burner. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the washing of flue gases from combustion furnaces and the like
IPC: B01D53/50
Filed: 1930-09-20
Abstract: Flue gases containing sulphur dioxide and oxygen are freed from sulphur dioxide by passing them through a chamber in co-current with an aqueous solution containing free ammonia.  Crude ammonia liquor from coal distillation may be employed in the process.  The ammonium sulphite initially formed is wholly or partially oxidized to ammonium sulphate by the oxygen also present.  Preferably, the process is so controlled that the solution leaving the chamber is slightly acid. The duration of the contact between the flue gases and solution may be about one second the solution having a temperature up to 50 DEG C.  The oxidation may if necessary be completed electrolytically, preferably in the presence of a chloride such as ammonium chloride or by treatment with an oxygen containing gas preferably in the presence of catalysts such as manganous salts, cuprous chloride, cobalt salts, iron salts preferably in the ferrous state or other heavy metal salts.  If cobalt salts are employed the solution should have a pH of about 8, but ferrous salts are preferably employed at a pH not exceeding 6.  Ferrous salts may also be present in the ammoniacal solution flowing in co-current with the flue gases and may be introduced by bringing the solution in contact with metallic iron, for example the internal surface of the apparatus.  The process may be carried out in a vertical tower both the flue gases and ammoniacal liquor entering near the top and leaving near the bottom, a fan being provided on the outlet side to draw the flue gases through the tower. The tower may be provided with baffles for example wooden slats and may be formed or coated with acid-resisting alloy steels.  The solution leaving the bottom after replenishment of the ammonia may be recirculated.  The ammonium sulphate is recovered by crystallization either intermittently from the whole body of the liquor or continuously by withdrawing a small proportion of the liquor from the circuit, the liquor removed being replaced by water.  Specifications 9432/99, [Class 1, Acids, alkalies, &c.], 356,283, and 356,757, [Group XXXVI], are referred to.

Abstract: 362,554. Wireless receiving apparatus. SPARKS-WITHINGTON CO., Jackson, Michigan, U.S.A.-(Assignees of Seeley, S.W.; 774, Audubon Avenue, Jackson, Michigan, U.S.A.) Sept. 23, 1930, No. 28430. Convention date, Oct. 5, 1929. [Class 40 (v).] A radio receiver is converted for use as a gramophone amplifier by plugging or switching in of the pick-up which adjusts the bias on the radio detector valve so that it may function as a first-stage amplifier for gramophone reproduction. As shown, the detector valve D is normally biased for plate- Current rectification by means of a resistance R2 in its cathode return lead. When the pick-up plug 24 is inserted in its jack J, a lower resistance R5 is connected in parallel with the resistance R2, the pick-up itself is inserted in series between grid and cathode, and the contacts 18, 19 are opened. The bias, which is due to plate current flowing through the resistances R2, R5, is thus reduced to a value suitable for operating the valve D as an amplifier. The Specification also describes the supply circuits for the radio receiver, the plate current being supplied from the mains through a transformer T5, rectifier RT, and smoothing elements 8 .. 14. The directly-heated output valves take their plate current from a point between the chokes 8, 9, and the high-frequency amplifiers A1 .. A5 are supplied from a point beyond the choke 9 through a circuit which includes the polarizing-coil 16 for the loudspeaker. Additional current for the coil 16 is carried through a resistance R3 shunted by a condenser. Grid bias for the amplifiers A1 .. A5 is provided by a fixed resistance Rc and a variable resistance Rvc in their plate circuits, the latter serving as a volume control. The Specification as open to inspection under Sect. 91 (3) (a) states that the change in grid bias may be effected by the switch which starts up the turntable motor. This subject-matter does not appear in the Specification as accepted.

Filed: 1929-09-19
Abstract: 340,242. Classifying and settling apparatus. ANDREWS, L., 11, Southampton Row, London. Sept. 19, 1929, No. 28434. [Class 82 (ii).] In connection with a classifying tank having one or more settling hoppers an underflow pipe of comparatively small bore is provided, communicating with the lower ends of the hoppers and through which liquid from the same source as that supplied to the classifier is passed at a high velocity. Means are provided for varying the relative proportion of the liquid passing through the classifier and the underflow pipe and for controlling the rate of flow through the outlet end of the underflow pipe, so that liquid may be caused to pass upward through the hoppers to remove finer material mixed with the heavier deposits therein or the heavier deposits may be discharged from the hoppers through the underflow pipe. Mixed material under treatment is received in a supply receptacle i, Fig. 1, and part passes thence through a pipe d and inverted cone d<x> into a classifier a and part through an underflow pipe c connected to the funnel-shaped lower portion of the receptacle i and through valves s with hoppers a<1> of the classifier. A valve d<1> controls the flow through the pipe d and thus the liquid level in the vessel i, and the relative amounts of liquid discharged through the pipes d, c. The outlet end of the pipe c is fitted with a valve c<2> and may be of reduced bore. It is connected to a supplementary classifier o, which may be of the kind described in Specification 340,027. The heavier deposits drawn from the hoppers a<1> separate in the classifier o and are discharged through an outlet o<1>. The finer material is carried by the liquid through a siphon r which discharges into a duct h into which the liquid and finer material from the classifier a is discharged through a pipe g. In modified apparatus shown in Fig. 2 the matter deposited in a supplementary classifier u is withdrawn by a pump 2 operated by an electric motor 10. A trickle of water is supplied to a tank 4 through a pipe 5 and water passes from the tank 4 to the vessel u through a pipe 3. An alteration of density in the vessel u causes the water level in the tank 4 and a float 6 therein to rise or fall, the movement being communicated by levers 7, 8 to a resistance device 9 in the circuit of the motor 10. The working of the pump 2 is thus regulated so as to maintain a constant density around the lower end of the pipe 3. Lighter matter passes from the vessel u through a pipe w to the inlet end of the classifier a.

Abstract: 933,182. Fluid pressure servomotor control systems. UNITED AIRCRAFT CORPORATION. Aug. 24, 1959 [Sept. 2, 1958], No. 28795/59. Class 135. A device for automatic stabilization of a helicopter comprises a rate gyro 90 which feeds a signal in response to rate of change of pitch or roll to a servomotor 94 having an output member 96. A lever 100, pivoted at 99, is connected at one end by a link 84 to a lever 82 while the other end is connected by leaf-springs 104, 106 to a shaft 108 of a rotary damper 114 which carries a lever 116 connected by a link 86 to lever 82. In operation movement of the output member 96 rotates lever 100, which through link 84 rotates lever 82 about a pivot 118, this pivot being held stationary due to the damper 104 which prevents immediate rotation of shaft 108. If the lever 100 remains in its rotated position for a certain length of time, i.e. the error has not been corrected, the shaft 108 will rotate and, through the link 86, cause rotation of lever 82 about the now stationary pivot 103. Movements of the lever 82 act through a link 83 to rotate a lever 79 about a pivot 130 to move a control valve 26, 28 of a moving cylinder servomotor 18 which acts through lever 72 and a link 74 on a swashplate 46 to vary the pitch of rotor blades 14. In a modification, the linkage between gyro 90 and control valve 26, 28 is replaced by an equivalent electrical transmission. A link 75 from the swashplate is connected to a duplicate system giving control in response to pitch and roll. A rod 129 from lever 79 leads to a manual control mechanism.
