Title: Improvements in and relating to the use of pulverized coal or liquid fuel as fuel for steam generators and the like
IPC: F23C99/00
Filed: 1927-08-11
Abstract: 302,255. Musker, A. Aug. 11, 1927. Gaseous and pulverulent fuel furnaces; ashpits; casings; cooling. - In an apparatus for burning powdered or gaseous fuel comprising a vertical combustion chamber 1 having a burner 12 at the upper end and a lateral outlet 2 for the combustion products at a lower level, the wall of the chamber is jacketed by a metal air heating casing 4, from which air is led by a connection 16 to the burners, and is also introduced into the chamber at a number of points through nozzles 20. Air is supplied to the casing by a fan 13, and in the powdered fuel apparatus shown a part of the heated air is delivered through ports 23 to the ashpit 7 and is deflected by a plate 25 into contact with the walls, which are thereby protected from erosion by falling ash. The lower part of the furnace is formed with an overhanging ledge 6. which deflects the ascending air currents inwards. The lateral outlet 2 is also jacketted and may have end air delivery ports 26. The ports 20 and 26 may be directed obliquely to impart a whirling motion to the gases. Fuel mixed with air is delivered by the pipe 11 to an annular conduit 18 surrounding the central duct 17 for hot air from the casing 4, and below the delivery orifices of these passages is a vertically adjustable cone 32, which may be perforated or may have flutings on its upper surface to give a whirling motion to the mixture of fuel and air. The combustion chamber may have two or more outlets supplying a corresponding number of flues in the steam generator. Specification 289.502 is referred to in the first Provisional Specification.

Title: Improvements in apparatus for grinding and polishing precious stones
IPC: B24B9/16
Filed: 1920-07-14
Abstract: 174,098. Marks, E. C. R., (New Diamond Polishing Tool Co. of America, Inc.), July 14, 1920. Gems, treating.-A precious stone is mounted, for grinding and polishing, in a conical dop 16 having thereon a gear 15, the teeth of which are adapted to be engaged by the tooth 14 of a spring- pressed latch, whereby different angular settings of the dop in the dop-holder 3 may be obtained. In order that the dop may be turned through an angular distance corresponding to a fraction of a tooth space, when dealing with stones of irregular form, the tooth 14 is carried by a stem 13 having a threaded part rotatably mounted in a bearing 11 pivoted to the dop-holder. Rotation of the stem moves this axially, and thus causes a slight rotation of the dop. The stem is pressed by a spring 17, which normally holds the tooth 14 in engagement with the gear, while allowing of disengagement for turning the dop through one or more tooth spaces of the gear. For varying the angle of inclination of the stone with respect to the rotating lap 4, an arc-shaped slide 6 on the dop-holder 3, a corresponding guideway 5 in the supporting-member 2, a pinion 8 meshing with the slide 6, and a binding-member 9 with nut 10 are provided. Specification 25482/13 is referred to.

Title: Improvements relating to electronic trigger circuits
Inventor: LONSDALE KEITH
IPC: H03K3/12
Filed: 1950-08-29
Abstract: 696,824. Valve multi-stable state circuits. FERRANTI, Ltd. Oct. 26, 1951 [Aug. 29, 1950], No. 21276/50. Class 40 (vi). In a trigger circuit comprising a cross-connected pair of valves voltages are derived from points in the circuit and applied to the control grids of the valves to oppose the application of the negative triggering pulse to that valve of the pair which is then in the non-conductive state. Fig. 2 shows a trigger pair in which valves 10 and 11 are cross-connected between anodes and suppressor grids. Capacitors 34, 44 are charged from the anode potentials of valves 10 and 11 respectively so that if the associated valve is cut-off the relatively high anode potential charges the capacitor to such a level that the negative trigger pulse applied from terminal 27 is substantially ineffective at the control grid of that valve. In modifications, Figs. 4 and 5 (not shown), the potential applied to the control grid to oppose the triggering voltage is derived from the screen-grid of the other valve of the pair. Fig. 3 shows a further modification in which the screen grid potentials of the trigger pair valves 10, 11 are applied to charge the capacitors 44, 34 in the control grid circuits of the other valve of the pair via the cathode follower stages 50, 51 respectively.

Patent GB-217398-A (GB)
Abstract: 217,398. Cordt, H., and Lindstrom Akt.-Ges., C. May 12, 1923. Type-wheel machines; aligning for impression. - In a multiple bank, key-set and crank-operated adding-machine having a differential mechanism of the Thomas type, the levers 3 pivoted at 6 and differentially moved by the keys to position the pinions 4 along the stepped barrels, carry also arms 7 supporting stepped segments 8 for co-operation with pins 9 on type-setting sectors 10. When the crank handle 15 is pulled forward, a universal bail 13 is swung to the right by means of a cam-controlled link 18 to allow the sectors 10, connected to the bail by springs 20, to move in the same direction until arrested by contact of the pins 9 with the set segments. The sectors gear with type-wheels 21 mounted in a frame pivoted at 25, and after the wheels have taken up their setting a cam on the crank shaft 14, acting through a lever 28, a spring, and a link 26, swings the frame to impress the type against a platen roll 30. The type-wheels are aligned by means of a comb 31 pivoted on shaft 25 and having its lines formed as detents. Normally, the type-wheels are free, but when the frame is rocked for impression a cam 32 rigidly secured to the link 26 forces the detents into engagement with the type-wheel pinions. To control the printing of zeros, a cross-bar 33 supported by levers 35 pivoted on a shaft 34 is raised at each operation of the machine and carries a number of slidable brackets 38, Fig. 6, interconnected by pins and slots and each controlled by a spring 40. The brackets have an upstanding arm 37 adapted in one position to lie beneath a corresponding lever 3 so that when the cross-bar is subsequently raised this lever is also moved to position the sector 8 and control the sector 10 to set the type-wheel with its zero in the printing line. When the link 18 is moved, a cam edge on the link, causes the brackets 38 to shift to the right to put their arms 37 out of the plane of the levers 3 or their extensions 7. If, however, a lever 3 has been moved by depression of a key, it rises alongside a forwardly projecting arm 41 of the corresponding bracket 38 and so prevents this and all brackets to the right from moving. Consequently, when the cross-bar 33 rises, all these brackets raise their levers 3 to effect the zero-printing.
