Title: Magnetic clutch coolant control
IPC: H02P29/00
Filed: 1964-02-12
Abstract: 1,004,819. Correspondence control. LOUIS ALLIS CO. Feb. 12,1964 [Feb. 21,1963], No. 5853/64. Heading G1N. Fluid cooling of a magnetic clutch is controlled by varying the rate of flow of coolant in dependence upon an electrical signal indicative of the instantaneous rate of heat generation in the clutch. The horse power loss in the clutch is indicative of the rate of heat generation. Inductor drum 20 of the clutch is driven by induction motor 11, and clutch rotor 21 drives load 12. The current supplied to field coil 25 on rotor 21 controls the output speed and torque of the clutch. A voltage indicative of this current is derived at 55 and applied to multiplier 60, e.g. a Hall device. A tachogenerator 41 on the clutch output shaft 13 provides a signal indicative of the output speed and from this signal, after rectification, is subtracted a reference voltage representative of the speed of induction motor 11. The difference represents the slip in the clutch and is also applied to multiplier 60. The product is stated to be proportional to the rate of heat generation. This signal is balanced against a reference value from battery 66 and the difference actuates either relay 68 or 69, depending on the polarity. As a result a motor 36 is driven to open or close a valve 35 controlling the flow of coolant to jacket 30 surrounding the clutch. In a modification a signal proportional to the horse power input to the clutch is supplied to the multiplier, instead of the clutch field current. A transformer is inserted in one of the input lines to induction motor 11 and the rectified secondary current is supplied to the multiplier. It is stated that the resultant product is also proportional to the horse power loss in the clutch. Instead of tachogenerator 41 a slip generator may be mounted on the output shaft of the clutch. This consists of a three phase rotor and a twelve phase stator, the stator windings being connected through rectifiers to a common positive output terminal, while the other ends of the windings are commonly connected to a negative terminal. The terminals are interconnected by a smoothing capacitor. The rotor is energized from the same source as driving motor 11 and is mounted so that it rotates in the opposite direction to the rotating field which it generates. At non- synchronous speeds an output is produced which is indicative of the continued slip of induction motor 11 and the clutch. A voltage representative of the slip of the induction motor is subtracted. Where wide variation in the rate of heat generation is likely, valve operating motor 36 may also drive the slider of potentiometer 67.

Title: Improvements relating to the recovery of sulphur from iron sulphide containing material
IPC: C01B17/06
Filed: 1931-02-27
Abstract: In the recovery of sulphur from iron sulphide containing material, which may also contain sulphides of other metals such as nickel and copper and be given a preliminary blast furnace treatment, the material is subjected to the action of gaseous hydrogen chloride in the presence of an agent, e.g. air, oxygen, carbon monoxide or dioxide, or flue gases whereby metallic chlorides and gaseous sulphur compounds, e.g. sulphur dioxide, sulphuretted hydrogen and carbon oxysulphide, are produced from which elementary sulphur is obtained. When air is used with the hydrogen chloride, temperatures of 400-800 DEG  C. may be employed, 600 DEG  C. being preferred; with carbon monoxide or dioxide, over 700 DEG  C. is maintained.  The carbon oxysulphide may be passed through water to convert it to sulphuretted hydrogen or burned with oxygen to sulphur dioxide.  The sulphur dioxide and sulphuretted hydrogen are caused to react in correct proportions in the presence of a catalyst, e.g. silica gel or bauxite, at normal or higher temperatures, e.g. 400-800 DEG  C.  To produce the correct amounts of the two gases, two operations are conducted simultaneously, one being operated under constant conditions as regards temperature and amounts of ore and gases introduced, the conditions of the other being varied according to the composition of the gases delivered by the first; the products are afterwards mingled to give a gas mixture of constant composition. The operations are conducted in two similar rotary reaction chambers maintained at 700 DEG  C. at the charging end and 300-400 DEG  C. at the discharging end where the hydrogen chloride and flue gases are introduced, the process being conducted continuously.  The reaction products are carbon oxysulphide, sulphuretted hydrogen, sulphur dioxide, and ferrous, copper, and nickel chlorides with a little sulphur vapour.  The gases are mixed, cooled to condense the sulphur vapour and passed into contact with water whereby any excess of hydrogen chloride is dissolved, the carbon oxysulphide is hydrolized and the sulphur dioxide and sulphuretted hydrogen caused to react to form sulphur.  Hydrogen chloride may be recovered from the hot residues.  Prior to treatment with hydrogen chloride, pyrites may be fused with coke and a flux, such as lime, in a blast furnace, the air supply being controlled so that the coke is burned to form carbon monoxide.  Sulphur is removed from the gases by condensation and carbon oxysulphide is hydrolized to sulphuretted hydrogen or oxidized to sulphur dioxide.  Ferrous and other sulphides are separated from slag by treatment in a settling apparatus and may be granulated by being sprayed into a shot tower communicating with the hydrogen chloride reaction chamber.

Abstract: 953,475. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 14, 1963 [Feb. 20, 1962], No. 6502/62. Heading G6C. A spacer ring 5, e.g. of alumina, interposed between the oblique faces of two tubular fuel elements 3, 4 comprises two similar semi-circular parts 5a, 5b engaging by lug and groove connections 6 and having projections 7a-7d extending in both axial directions. The projections are part spherical in contour where they abut the wall of the surrounding coolant channel 2. The grooves of the connections 6 are formed oversize to provide clearances 6a in order to accommodate expansion of the ring 5 in operation, whilst the faces 6b closely engage each other. The projections 7a, 7b on the upper part 5a of the ring 5 extend radially to the channel wall and downwardly so as to overlap the edge of the lower fuel tube 4 while the projections 7c, 7d on the lower part 5b similarly extend to the channel wall but also upwardly to overlap the edge of the upper fuel tube 3. The peripheral portion of the ring 5 between the projections 7c, 7d subtends an angle at the channel axis whose bisector lies along the line of the radial component of the axial force to which the fuel tubes are subjected set up by virtue of the inclined planes of contact between the fuel tubes 3, 4 and the ring 5. This radial component serves to hold the fuel tubes 3, 4 steadily in a central position within the channel 2. Dimensional changes in the fuel tubes 3, 4 and the ring 5 can be accommodated under operating conditions by sliding in the inclined planes of contact between them.

Title: Improvements in machine for spot welding, making spark plugs and other objects wholly or partly of metal by applying heat and pressure by means of a pair of electrodes
IPC: B23K11/11
Filed: 1930-02-28
Abstract: 349,610. Heating by electricity. A.C. SPARK PLUG CO., Flint, Michigan, U.S.A. Feb. 28, 1930, No. 6755. Convention date, Sept. 26, 1929. [Class 39 (iii).] A machine for applying heat and pressure by means of a pair of electrodes to an object wholly or partly of metal has means to cut off the source of heat upon a predetermined collapse of the metal. Fig. 1 shows a machine, for applying heat and pressure to spark-plugs of the kind having a thin wall-portion, between upper and lower gaskets, adapted to be softened and deformed to make the gaskets tight. A plug is inserted in a work holder 7, which is lowered by an eccentric 9 and then raised to press the plug into a holder 27 carried by a piston 19 normally held up by a spring 21. A hand-lever 38 is moved in a counterclockwise direction to open a valve 31, admitting compressed air above the piston 19, and close a switch 45 which energizes solenoids 115, 107 to advance a latch 53 against a spring 57, lock the lever 38, and close a double pole-switch 103 which causes a transformer 101 to supply heating current to the holders 7, 27. The advance of the latch 53 also rotates an eccentric 60 to lock a slide 61, carrying an electric contact 79, to the frame. As the plug expands by the heat the holder 27 is moved up and with it spring- mounted contacts 81, 89 carried by an arm 64. A spring-mounted bar 67 also moves up but it only compresses a spring 77. When the plug softens and yields the arm 64 moves down, thus closing the contacts 81, 79 to energize solenoid 105, thus opening switches g and 103 and cutting off the heat. Further movement of the arm 64, due to cooling, closes contacts 81, 89 to energize solenoid 113, open switch k and de-energize solenoid 115, thus allowing spring 57, 47, 21, 73, 77, to return the latch 53, lever 38, piston 19 and slide 61 to their original position. The amount of deformation and duration of subsequent pressure may be regulated by adjusting contacts 79, 89 by nuts 71, 93. For spot-welding the work 26, Fig. 2, is clamped on a fixed electrode 4 by an electrode 6 moved down by a pedal 22 which closes a switch 28 thereby energizing solenoids 380, 52, to clamp a slide 32 in a bracket 30 on the electrode 6 and to close switches 152 and start heating current through leads 56. When the work softens the electrode 6 moves down, by reason of a spring 16 and a feeler 40, which engages the unsoftened work and remains stationary, closes contacts 44, 46 to energize a solenoid 580, controlling a switch 158, thus stopping heating current and releasing the slide 32.
