Title: Improvements in or relating to the manufacture of water gas
IPC: C10J3/00
Filed: 1926-01-06
Abstract: 269,234. Nielsen, H., and Laing, B. Jan. 6, 1926. Coking processes; producers.-In a continuous process of making water gas, the temperature of the reaction is maintained by the addition to the steam of an inert gas, or an inert gas mixed with carbon - dioxide, heated to a temperature above that at which the reaction takes place, a suitable temperature bein? 1000‹ to 1200‹ C. The steam may also be superheated and the sensible heat of the resultant hot gases may be utilized by passing them through a retort to distil carbonaceous materials therein. The mixed retort gases and water gas may, after removal of the condensates, be used as the inert gas of the process. The mixed retort and water gas may be re-circulated through the retort. One of two chambers 6 containing chequer brickwork used alternately is heated by combustion gases entering it at inlet 8 and leaving by outlet 9. Steam and the inert gas is then admitted by pipe 11, is heated in the chamber 6 and enters chamber 1 by passage 10. Semi-coke is charged into chamber 1 and rests in superimposed shelves 2 when the reaction takes place in the space between the shelves, the residue falling into an ash pit 1<a>. The superheated steam passes by channels 5 through the charge and the gases and vapours cooled pass to an outlet 12. The steam may instead be admitted through an inlet adjacent to the passage 10.

Patent GB-741567-A (GB)
Title: A method of making high-grade steel
IPC: C21C7/10
Filed: 1953-01-08
Abstract: Molten steel is treated with a gas containing at least 75 per cent of oxygen and then subjected under a strongly deoxidizing slag, to a low absolute pressure.  The slag should be free from heavy metal oxides and components having a low vapour pressure at the working temperature.  The pressure may be reduced to 3 to 20 mms. and the space above the bath may be heated, e.g. by an electric arc.  Both oxygen and sulphur are stated to be removed by the process.

Title: Gear pump
IPC: F04C15/00
Filed: 1970-01-06
Abstract: 1291381 Rotary positive-displacement pumps CHANDLER EVANS INC 6 Jan 1970 [3 March 1969] 630/70 Heading F1F In a gear pump pressure-loaded check-plates 35, 36 abut the end faces of gears 6, 7 and a movable element 17 comprising an outlet 18 for the working fluid and surfaces 53, 56 that are wiped by the tips of the gear teeth. To keep said surfaces in contact with the gears wedgemembers 20, 21 are pressed outwardly by spring and pressure-loaded pistons 26, 27. The angle of inclination of surfaces 24, 25 engaged by the members 20, 21 is rendered small so that owing to friction the thrust acting on the element 17 due to the pistons is substantially just sufficient to balance the thrust due to fluid in the tooth spaces adjacent the surfaces 53, 56, the radial load applied to each tooth abutting the element being thus substantially nil. The loads carried by bearings for the gears are thereby minimized. Pressure-loading chambers 43, 46, 49, 50 for the check-plates are formed in housing end-plates 3, 4. The members 20, 21 may be replaced by rollers, Fig. 5 (not shown).

Patent GB-737410-A (GB)
Title: Improvements in electro-optical scanning systems
IPC: H04N1/40
Filed: 1953-01-09
Abstract: 737,410. Copying by scanning. EASTMAN KODAK CO. Jan. 9, 1953 [Aug. 28, 1952], No. 757/53. Class 40 (3). In a photo-electric scanning system in which a photo-electric cell receives a variable intensity light signal from a scanned subject during scanning intervals and a reference intensity light signal during non-scanning intervals the magnitude of the output signal from the cell during the latter intervals is employed to control the operation of the system such as to maintain constant the factor of proportionality between variations of the light signal and corresponding variations of the cell output signal during a subsequent scanning interval. As shown in the drawing electrical signals, generated in a photo-electric cell 25 by scanning a subject, e.g. a transparency 11, modulate a carrier wave from source 31 in valve 27, the modulated carrier being fed, via an amplifier 46, to utilization apparatus 48 comprising e.g. amplification, gamma control, and marking circuits and a recording device. A second valve 34, having an anode load resistance 39 in common with valve 27, is supplied with carrier from source 31 in phase opposition to the carrier supplied to valve 27 so that in the absence of a modulating signal from cell 25 zero (carrier) output is developed across resistance 39. If, due to variations which upset the balance of the circuit including the valves 27, 34 a (spurious) variation (modulation) of the carrier is produced (in the absence of a modulating signal from cell 25) the resultant signal developed across resistance 39 is effective, after amplification in valve 46, to render one or other of two gas-discharge valves 52, 53 conductive and to develop in the load circuits of diodes 61 or 62 a control voltage which is fed over line 66 to vary the voltage on the control grid of valve 34 so as to restore the balance. The polarity of the control voltage depends on which of the valves 52, 63 conduct and this depends on the relative phases of the voltage supplied to the grids 49, 51 from valve 46 and the voltage supplied to the anodes from the carrier source 31. The correcting effect is developed (momentarily) once per revolution of the drum 12 by means of a cam-operated switch 57 in the circuit between source 31 and valves 51, 52 and during this interval a predetermined intensity of light is arranged to be incident on the cell 25, e.g. by providing an opaque portion 73 between the ends of the transparency being scanned.

Title: Machine for bending metal bars and the like
IPC: B21D11/12
Filed: 1920-01-12
Abstract: 137,822. Runback, K. G. M. Jan. 11, 1919, [Convention date]. Angular bending.-In a machine for bending metal rods and bars for concrete reinforcements &c., of the type in which the bar is passed between two stops round one of which it is bent by a pin on a disk which is driven so as to give a periodic oscillatory movement with an interval after every period, the disk is driven by a rope secured to a crank. In the form shown in Fig. 1, the bar 7 is placed between two fixed stops 1, 4 and is bent by a pin 6 on a grooved disk 5 recessed into the table 2 to which is secured a rope 11 connected to a crank-pin 12 and passing over a roller 13 on a screw-adjusted slide 14, so as to vary the length of the interval and thus the angle of the bend. A scale may be provided along the guides. The stop 1 passes through a slot 3 in the disk 5, which, when the crank reaches its farthest dead point, is returned to its initial position by a weight attached to a cord passing round a pulley on the spindle 4. The stop 1 is longer than stops 4 and 6 to prevent the bar if it slides upwards from coming out of engagement with the stop 1 while it is still engaged by the stops 4 and 6. The crank 17 is covered by a disk 18 to prevent the rope from fouling the crank. In a modification, the stop 1 is replaced by a stop 21, Fig. 3, secured outside the disk 25, and in a further modification, Fig. 4, the disk 27 is mounted beneath the surface of the table, the pin 29 passing through a curved slot 31 in the table and through a hole in a dust-excluding disk 32, through which also the shaft 30 passes. In curving a bar to a large radius, the machine is adjusted for a small angle of bend, and the bar fed forward between each operation.
