Title: Improvements in and relating to the automatic control of concentration of solutions
IPC: C10K1/10
Filed: 1943-02-16
Abstract: 567,261. Controlling concentration of ammonia liquid. HOLMES & CO., Ltd., W. C., and COOPER, C. Feb. 16, 1943, No. 2523. [Class 55 (ii)] [Also in Group II] The concentration of an aqueous solution is regulated by balancing a column of the solution against a column of another liquid of constant or approximately constant composition and then causing variations in the difference in height of the columns to vary the supply of water to such aqueous solution. The concentration of ammonia in the gases leaving a gas washer by adjusting the concentration of ammonia liquor in the washer by varying the amount of water fed to the washer in accordance with the difference in density between the liquor and a constant comparison liquid, e.g. water or oils. As shown, a small pipe 1 is threaded into a larger vertical pipe 2 of height from 6-10 feet, the inner pipe being fed with clean water and the outer with ammonia liquor and the two pipes being in communication at the foot 3. Ammonia liquor from the washer 8 is slowly fed through pipe 19 into funnel 20, whence it passes to the foot 3 of the column. Fresh water is supplied by pipe 22 to the funnel 23 terminating pipe 1, pipe 2 being terminated by funnel 24, which is surrounded by the funnel 4 carrying the surplus from the balancing device via pipe 18 to the tank 7. The main water supply is carried via pipe 31 and float valve 5 to tank 6 containing two siphons 10 and 11, the first being always submerged when the water in tank 6 is at its maximum level and continuously siphoning out at a comparatively small rate. Siphon 10 is connected via pipe 14 with the openmouthed tube 15 placed very close to the level of the water in pipe 1 and via pipe 13 with the vertex of the large siphon 11. When tube 15 becomes submerged, the suction created by .siphon 10 draws water into the main siphon 11 which quickly empties tank 6 into tank 7 whence the water passes via pipe 9 to the washer 8 and the action is repeated until the ammonia liquor reaches the desired concentration and the water level in pipe 1 falls to unseal pipe 15 and interrupt the flow. The outlet ends of the siphons are sealed by the small tank 17 in tank 7. A hand-control water feed 16 is also provided. In a modification a central tube charged with oil is provided within the tube 1. In a further modification, to provide for large rates of water admission the discharge from siphon 11 is led into a small vessel riding on the ball of a ball valve controlling the supply of water to tank 7 and hence to washer 8. Siphon 11 is provided with a seal on its length. Temperature changes may be allowed for by arranging the height of the column so that the change of density of the solution due to temperature just balances the change in level due to expansion. The rise and fall in the water level in pipe 1 may be used to tilt a mercury switch and turn on or off a water supply by electrical means. Specifications 162,166, 331,592, 331,818, [all in Class 55 (ii)], and 357,712 are referred to.

Abstract: 216,552. Miles, W., Thomas, W., and Hallowes, W. B. Jan. 29, 1923. Angular bending; rolling.-A machine for use in connection with rolling mills for doubling steel &c. sheets in the manufacture of tin plates, terne plates and black plates &c. comprises a bed-plate above which is arranged a former round which . the sheet is doubled by arms or levers which are adapted to penetrate, slots in the bed-plate. The sheet is placed against a segmental guide d<1>, and an angle iron n on the bed-plate a and is bent round a former e by a number of curved arms l<2> connected by a cross-bar and mounted on a shaft b, which is rotated by a pinion and spur wheel c operated by an hydraulic ram z through a weighted lever k secured to the wheel c. The bending arms pass through slots in the bed-plate. The former e is arranged to slide into and out of operative position in a bracket o, being provided with a lug b<1> guided in a. slotted angle plate d<3>. A rope a<1> is secured to the lug b<1>, one end of the rope being secured to a sliding weight k<1> and passing over guide pulleys j<1>, g<1> to the lug and the other end of the rope being secured to the under side of a slide c<1> and passing under a pulley d<2> and over two more guide pulleys to the lug. On depressing a pedal y<2> a weighted pedal lever v<2> is raised so as to operate a cranked lever t<2> which trips a slotted lever o<1> carried by the slide c' off the lever k and so allows the weight k<1> and slide c' to drop and thus bring forward the former e over the sheet as the pedal continues its downward strode the lever v<2> raises a rod c<3> and operates a valve x<2> to admit fluid to the cylinder r. The cam is thus operated to push down the lever k and thus rotate the bending arms. The end of the lever k presses the lever o<1> against a spring and when it enters the slot in the lever o' the spring pushes back the lever o<1>. On releasing the pedal the valve x<2> is operated to open the cylinder to exhaust and the weight w raises the lever k which carries with it the slide c<1> into its initial position and thus withdraws the former e. The right hand end of the bed plate is gapped so that the sheet may be gripped by tongs. According to the Provisional Specification the gearing is driven by a lever operated by a crank-pin fixed in a wheel on the mill-shafting or by a separate electric motor.

Title: Improvements in or relating to remote-control electric circuits
IPC: H01B7/00
Filed: 1952-02-01
Abstract: 716,516. Protective cut-out arrangements. ETABLISSEMENTS MERLIN & GERIN. Feb, 1, 1952 [March 6, 1951], No. 2708/52. Class 38(5). [Also in Group XXXVI] A cable 11 supplying apparatus 10 and comprising power conductors a, b, c. one or more pilot wires 1, each provided with an insulating sheath and embedded in a body 5 of conductive rubber associated with a metallic conductor 2, in the form of a sheath or sheaths coaxially about the insulation of the pilot wire or wires, is provided with a protective cut-out arrangement. A transformer 19 is energized when switch 8 is closed. and supplies alternating current to a rectifying circuit 24. Direct current flows in conductor 23 and potentiometer 25. The grids of an electron tube 27 are biased so that the direct current supplied by circuit 24 flows permanently in the circuit 26<SP>1</SP>, 26<SP>2</SP>, as long as the insulation,in the apparatus 10 and cable 11 is satisfactory, thus closing the contact 21 of relay 20. The circuit including the relay 13 is thus closed, and a small pulsating current permanently carried by the pilot conductor 1 thus flows through it, but is too small to close the contacts of relay 13. To energize the apparatus 10, a push button 15 is depressed, short-circuiting resistance 18. This creates a strong pulsating current which closes relay 13. Coil 12 is thus energized and contactors 9 closed. On releasing push button 15 the pulsating current falls to its initial value, which is sufficient to keep the relay 13 closed. In the event of an insulation fault in the apparatus 10, current flows through the supply line, point 29, circuit 33. resistance 44 and potentiometer 25 to earth. This causes a negative bias on grid G1  with respect to the cathode and thus interrupts the circuit through relay 20, opening contactor 21 and relay 13. Coil 12 is de-energized and contactors 9 open. An insulation fault in the cable 11 causes current to flow through the conductive sheath 5, conductor 2, circuit 28, resistance 46 and potentiometer 25 to earth. The grid 63 is biased negatively with respect to the cathode, interrupting the circuits through the relays and opening the contactors 9 as above. Specification 702,097 is referred to.

Filed: 1916-02-24
Abstract: 101,306. Carroll, L. D., (Chrisman, C. S.). Feb. 24, 1916. Retort furnaces; charging and discharging; cooling discharged materials.-Apparatus for making coal gas comprises a number of vertical retorts in one furnace or retort chamber, one or some of which retorts communicate directly with one or more producers supplying the gas to heat all the retorts, pressure-adjusting means being provided at the base of the retorts communicating with the producers so as to exclude producer gas therefrom. The apparatus shown comprises retorts 3 for making coal - gas and coke, and one or more retorts 4 which open at their lower end into a producer 5 supplied with air at 6. Air supplied at 21 is heated in passing over the lower ends of the retorts 3, which may be of castiron and provided with cooling-rings, and enters the combustion chamber 8 for the producer gas through passages 7. The burnt gases pass through an opening 10 in part around a baffle 11, and in part around a baffle 12 and through side flues 13, to an off-take 14 with dampers 16, 17. Steam supplied through connexions 23 to the bottom of the retorts assists the cooling of the coke. Entry of producer gas into the retort 4, and of coal gas into the producer, is prevented by adjusting the pressure at the base of the retort, two arrangements which may be used separately or in combination being described. The first comprises a coal-gas jet 26, which is arranged in the outlet from the retort, and the supply to which is regulated bv a valve 28 automatically controlled bv an inverted bell 30 dipping into liquid and subjected on its underside to the pressure obtaining at the throat 24, which is communicated by a pipe 29. The second arrangement comprises a steam jet 32 which discharges at or near the throat and may be similarly automatically regulated. Fuel is fed to the retorts by an elevator 34, hopper 35, and conveyer 33. lf the conveyer becomes jammed with fuel, the lower end of the lever 41 is displaced and the clutch 39 disconnected from the driving-wheel 38. Coke is removed from the retorts by a screw conveyer 44 fed by arms 46, Fig. 5, which are vibrated by links 49 connected by radially adjustable pins to an oscillating disk 50.

Filed: 1966-01-21
Abstract: 1,111,397. Refrigerators. WESTINGHOUSE ELECTRIC CORPORATION. 21 Jan., 1966 [8 Feb., 1965 (3)], No. 2785/66. Heading F4H. In a refrigerator having an evaporator compartment 13 communicating through valve controlled openings 16 and 18 with a freezer compartment 11 and through valve controlled openings 17 and 19 with an above-freezing compartment 12, means are provided to control the refrigeration circuit and to allow circulation of air either between the evaporator 14 and the freezer compartment or between the evaporator and the above-freezing compartment according to the temperature in the evaporator compartment 13. As illustrated openings 16, 17, 18 and 19 are controlled by pivoted flaps 21, 23, 26 and 28 operated through links 31 and 32 and a rod 33 by longitudinal movement of a rod 38. Rods 33 and 38 are connected through springs 36 and 37, so that rod 38 may be moved beyond the closing position of the flap valves to ensure adequate sealing. The rod 38 is moved by a crank 42 mounted on the shaft 43 of a motor 44 which also rotates a cam 69 operating a double pole switch 68. In the condition illustrated a fan 46 circulates air between the evaporator 14 and the above-freezing compartment and the compressor 67 of the refrigeration system is inoperative. When the air temperature sensed by a bulb 59 rises to a given value a thermostat 61 closes a switch 62 to energize the compressor 67 and to rotate the motor shaft 43 through 180 degrees when the switch 68 stops the motor 44 and the flap valves are in a position to circulate air through the freezer compartment. When the temperature sensed by the bulb 59 falls to a given value the switch 62 opens to de-energize the compressor and rotate the shaft 43 through a further 180 degrees to reinstate the former condition of operation. During circulation of air through the abovefreezing compartment any frost on the evaporator melts and is carried away by any suitable means. In a modification. Fig. 4 (not shown), two flap valves (47 and 48) control the air flow and are operated by longitudinally movable rods (52 and 53) and links (49 and 51), the connection between the links and flaps being provided by spring members (57), Fig. 5 (not shown), to allow a sealing force to be applied to the flaps. In a further modification, Fig. 6 (not shown), the apparatus is designed to operate at high ambient temperatures and includes a bulb (66) in the evaporator compartment 13, a thermostat (64) and a switch (63) so arranged that when thermostat 61 starts the compressor 67, circulation of air through the freezer compartment is delayed until the above-freezing compartment temperature has fallen to a given value.
