Title: Improvements in the desulphurisation and concentration of sulphide iron ores
IPC: C22B1/11
Filed: 1924-03-07
Abstract: Sulphide ores of iron, e.g. iron pyrites or pyrrhotite are desulphurized by treatment with sulphur dioxide at a gradually increasing temperature which does not exceed 950 DEG  C.  The hot gases containing sulphur dioxide first liberate the more mobile portion of the sulphur and the resulting ferrous sulphide reacts with the sulphur dioxide in the hottest part of the furnace or in a separate furnace to give porous magnetic oxide of iron and free sulphur.  The latter is passed to condensation chambers and the iron oxide is subjected to the usual electromagnetic separation process in order to concentrate it, when it may be briquetted. The sulphur dioxide may be obtained by burning sulphur or pyrites in air in burners of the usual type, but the resulting hot gases should not contain more than one per cent of oxygen.  The reaction is facilitated by the regulated admission of steam.
Patent GB-1298763-A (GB)
Title: Fuel injection system for an internal combustion engine
IPC: F02M45/04
Filed: 1970-02-06
Abstract: 1298763 Fuel injection control PHYSICS INTERNATIONAL CO 6 Feb 1970 [6 Feb 1969] 5917/70 Heading G1N In a diesel engine fuel injection control system, a small quantity of fuel is injected into each cylinder a variable period, determined by engine speed, before the main injection of fuel into each cylinder, the main injection occurring at a fixed crank angle. As shown, the engine rotates a cam 30 which operates three switches 32, 34, 35. Upon closure of switch 32, a ramp generator 42 generates a voltage V 1  which maintains a value V 2  when the main switch 34 is closed, the voltage V 2  being held by a circuit 50 after a delay. Closure of the switch 34 also applies a pulse through a starter switch 66 to an amplifier 68, an electronic switch 102, and a main pulse width control 104. Operation of switch 102 allows a main injection power supply 100, adjusted by an operator's control 109 and a control and governer circuit 108, Fig.3 (not shown), to energize an electro-expansive pump 82 for a cylinder for a duration determined by the main pulse width control 104. Circuits are reset by the switch 35 and on the next cycle closure of switch 32 again starts generators 42 and 44. The voltage V 2  held in 50 during the previous cycle has subtracted from it a voltage V 3  representative of engine parameters, e.g. temperature, octane number, to provide a voltage V 4  which is compared at 62 with the voltage V 5  of the generator 44. When the voltages V 4  and V 5  become equal a pulse is produced which is applied, via a switch 90, to an electronic switch 92 and a pilot pulse width control 94. Operation of the switch 92 allows a pilot power supply 84 to energize the electroexpansive pump 82 for a duration set by the control 94. Main injection then follows when switch 34 is closed. The pilot power supply 84 may be adjusted by engine parameters. During starting the switch 90 is opened to prevent pilot injection, and the switch 66 is operated to delay the main injection for a period depending on engine temperature. One such system described is provided for each engine cylinder. In a modification for a four cylinder engine, Fig.4 (not shown), four main switches 34a-34d and four main pulse shaping circuits 46a-46d are provided, one for each cylinder, each switch forming the start and reset switch for a succeeding and preceding main switch respectively. In a further modification for a four cylinder engine, Fig.5 (not shown), again four main switches and four main pulse shaping circuits are provided, the outputs of the pulse shaping circuits (146a-146d) being applied both to the main injector control and to an OR gate (149) which is connected to a ramp generator (152) and sample and hold circuit (150) for providing the voltage V 2 . The switches are connected to respective AND gates (148a-148d), the other inputs of the AND gate being connected to the output of the comparator of the voltages V 4  and V 5 . The output of each AND gate is connected to a respective pilot control.

Title: Improvements in and relating to coin-freed amusement devices
IPC: G07F17/34
Filed: 1937-03-01
Abstract: 493,137. Coin-freed amusement apparatus. TRIGGS, W. W., and HEIDTMANN, H. (Momm. E., [in part]) March 1, 1937, No. 6109. [Class 27] [Also in Group XV] In an amusement apparatus in which a ball runs down an inclined spiral track and enters one of a number of scoring apertures in a central rotating member, coin-freed means are provided to set the apparatus in an operative condition. As shown, the coin-freed means enables the ball to be released by the player on to the spiral track at a moment selected bv him. The ball normally lies in an inclined channel 23 against a stop plunger 21, the plunger being withdrawn by a spring 22, when released by an electromagnetically-actuated latch 16 upon insertion of a coin, the ball then entering the opening in which the plunger works. Upon actuation of a now extended push-rod 17, the plunger is relatched in extended position, and the ball discharged on to a spiral runway 25 formed in a dished annular element 27. At the centre of this element is a receiver 28, rotated by an electric motor 29 and provided with a number of radial ball receiving passages 34 of differing widths and having discharge apertures 36 towards their inner ends communicating at an aperture in a fixed plate 37 with a series of semicircular channels 39 carried on a series of counterweighted rocking beams 40. The ball consequently enters one of passages 34, a corresponding channel 39 on a beam 40 which it rocks, and is finally discharged to a worm conveyer 61 which returns it to channel 23. Except in the case of the widest passage 34, the rocking of a beam 40 closes a respective contact 43 which energizes a latching relay 44 and illuminates a corresponding signal lamp 47. Relay 44 prepares at contacts 46 a circuit for releasing any one door 6 of one of a number of groups of prize-article compartments, there being a separate group of compartments to each scoring channel 39 and size of target passage 34 except the widest. The illumination of a signal lamp 47 indicates to the player that he is entitled to a prize from one group of compartments. He thereupon turns a knob 49 corresponding to that group to the selected compartment and then depresses it. This completes the circuit through one of contacts 48 to a solenoid 51 which releases the latch 55 holding the door of the compartment closed. Simultaneously, contacts 56 are closed which energizes a relay 57 to release relay 44 and restore the circuits to normal. A switch 62 inaccessible to the player is provided to enable the compartments to be opened for filling. Coin-action, weight.-An inserted coin passes down a channel 8 and rocks a pivoted flap 10 which momentarily closes contacts 12 to energize the magnet 15 of latch 16.
