Title: Improved process for the heat treatment of carbonaceous and other materials
IPC: C10B7/00
Filed: 1929-07-30
Abstract: 338,939. Salerni, E. M., and E. M. S. Industrial Processes, Ltd. July 30, 1929. Charges, agitating and conveying.-In the heat treatment of solid carbonaceous and other materials, such as by evaporating liquids or solutions of salts, the materials during their continuous passage through a chamber or retort in one direction are subjected to a secondary movement in a direction opposed to or at variance with the general flow of the material " en masse " through the apparatus. The means employed to effect this movement are wholly submerged in the material. In an apparatus comprising a number of juxtaposed troughs 6, the material is fed from the inlet hopper 2 and discharged from an outlet 3, and paddles 7 rotated in an anti-clockwise direction propel the material against the general flow sufficiently to pile it up but not sufficiently to overcome the gradual passage through the apparatus. Specifications 224,568 and 273,528 are referred to.

Filed: 1953-08-27
Abstract: 743,037. Motor power plant. BAGGERUD, O. J. Aug. 27, 1953, No. 23646/53. Class 110(3) In a marine steam power plant comprising a reciprocating engine having low and high pressure stages and auxiliary equipment driven by boiler steam, a multi-stage or mixed pressure 'turbine is provided, with means 'for connecting the turbine directly to the boiler, the low pressure cylinder of the engine and excess auxiliary exhaust, so as to be capable of taking steam at three different points. In the marine power plant shown, steam from one or more boilers 1 is supplied through pipe 28 to a reciprocating engine 2 and through pipe 27 to auxiliaries 3. At full power, a mixed pressure turbine 12 re- 'ceives live steam at inlet 13 through pipe 29 and exhaust steam from the auxiliaries 3 and engine 2 at intermediate inlets 13a and 14 respectively. The turbine exhausts to a condenser 15. Valves 16, 21, 22 allow the exhaust from the engine 2 and auxiliaries 3 to be directed to the condenser 15 instead of to the turbine 12. Some cf the exhaust from the auxiliaries, 3 may be used, as shown, in a preheater H for the boiler feed water. The propeller shaft 5 is directly driven by the engine 2 through a coupling having two wedges 4 which can be removed to disconnect the drive. The shaft 5 is also driven by the turbine 12 through gearing 10, 7, 6 and a hydraulic coupling 9. At intermediate power, the supply of live steam to turbine 12 is cut off. At low power and for manoeuvring, the turbine 12 is disconnected from the shaft 5 by emptying the coupling 9 and may be kept running so as to continue driving a generator 25; additionally, when the vessel is in port, the engine 2 is shut down. In the embodiment shown, the turbine inlet 13 and the engine 2 are supplied with superheated steam and the auxiliaries 3 are supplied with unsuperheated steam. In a modification, the engine 2 is supplied through a mixing valve with a mixture of superheated and unsuperheated steam. In a further modification, the superheater has a high temperature section which supplies the turbine inlet 13 and a medium temperature section which supplies the engine 2.

Filed: 1926-06-16
Abstract: 267,328. Igranic Electric Co., Ltd., and Spaink, J. H. Abbink-. June 16, 1926. Retarding and time-limit devices; electricmotor actuation; switches, actuating.-In a timing apparatus which is driven through an electromagnetic clutch and after performing its function is released by the clutch and permitted to return to a normal position, the clutch has a field winding which rotates with one of the clutch elements and is energized through slip-rings carried by said elements. In the arrangement shown in Fig. 1, the electric switch 1 when closed causes operation of a relay 3 which connects the motor and electromagnetic clutch 5 across the supply lines. The rotation of the motor after a predetermined time causes a projection 12 carried by the clutch armature to close a switch 13 so energizing a relay 2 which completes its own maintaining circuit and also de-energizes the motor and clutch 5 permitting the member 12 to be returned by a spring to its initial position. The controlled circuit 15, 16 may be subsequently opened by the opening of switch 4 and consequent de-energization of the relay 2. The clutch shown in Figs. 2, and 4 has the ends of the winding 5a of the electromagnet 5<b>, which is secured on the shaft 17, brought to slip-rings 7, 8 on which bear fixed brushes 6, 9. The plate armature 5<c> is loosely mounted on the shaft 17 and the arm 12 is normally held in its starting position by a helical spring 11 connected between the plate 5<c> and a fixed post. To vary the initial position of the arm 12 it is carried by a peripheral band 28 adjustable in a groove surrounding the plate 5<c>. The electromagnet energizing coil is protected by a shield 27 bolted to the face of the electromagnet 5b on which the attracted plate 5<c> is adapted to bear. A number of such clutches may be driven by a common motor for producing operations after different or similar time intervals.

Abstract: 355,011. Variable speed gearing. VIEWING, F. G. P., 19, Fulford Road, West Ewell, Surrey. Aug. 8, 1930, No. 23742. [Classes 80 (ii) and 80 (iii).] A variable-speed ratchet or like gear comprises an automatically-variable driving- crank g and a reversible one-way driving- device comprising toothed pinions m, m<1> constantly in mesh with a driven spur wheel k and adapted to lock and unlock as the stroke changes direction. The crank pin g, Fig. 2, is carried by a centrifugal arm c pivoted eccentrically at d to a disc b fast on a power shaft. The pin g is biassed towards a central no-drive position by an adjustable spring e with an abutment e<1> fixed to the disc b. An automatically variable drive is set up by a balance between centrifugal force on the arm c and the thrust of spring e. The one-way pinions m, m<1> are supported in arcuate slots n in carrier arms h, i oscillating loosely on the driven shaft j to which wheel k is secured. When arm i moves to the left of Fig. 3, loose pinion m rolls into locking engagement with pinion m<1>, and there is drive to wheel h. Pinion m<1> is held at the right end of slot n by a swell y on slider v. On the return stroke, pinion m drops back to free position, unlocking the drive. To reverse the drive, sliders v are moved radially so that swells y move clear of pinions m<1> and swells w obstruct the movement of pinions m. This is effected by a cone q, Fig. 4, which engages bowls s on the sliders moving them against springs u.
