Patent GB-1072622-A (GB)
Title: Method of controlling the operation of a blast furnace
IPC: C21B7/24
Filed: 1964-06-24
Abstract: In the operation of a blast furnace the optimum blast pressure and top gas condition (as determined generally by its temperature but alternatively by its composition) for any given charge and operating practice are first determined, and are thereafter maintained by controlling the blast rate and the moisture content increased, when blast pressure and/or top gas temperature are above optimum.  The amount by which the controllable factors are increased or decreased may be proportional to the deviation of blast pressure or top gas temperature from the optimum, but when blast pressure is high the resultant reduction in blast rate should be double that for a similar variation of pressure below the optimum.

Filed: 1972-06-06
Abstract: 1361320 Boots CENTRE TECHNIQUE DU CUIR 6 June 1972 [18 June 1971] 26234/72 Heading A3B  In order to produce a range of styles of lasts using turning techniques a last 2 (Fig. 4) consists of a basic standard heel element 2b (whose shape does not change with changing fashion) and an interchangeable toe element 2a whose shape is dependent upon fashion, the two elements 2a, 2b having the intersection points of the turning axis 3 marked on their ends 23, 25 and on their abutting faces, these marks being used to locate the means for interconnecting and positioning of the two elements 2a, 2b. As described the two elements 2a, 2b are provided with bores 11, 12 respectively which are co-axial with the turning axis 3, and each element is also provided with a cross bore 14, 15. The two elements are joined by means of a stud 13 having cross bores 18, 19 and two cross pins 16, 17, the pin 16 passing through bores 14, 18 and the pin 17 passing through bores 15, 19. Since the heel element 2b does not change with fashion, these elements can be mass produced in the range of sizes required. The toe element 2a depends on the fashion required and is produced as follows. Initially a prototype or pattern of the required last 2 is made (e.g. by hand) and this pattern is cut into two elements in the apparatus shown in Fig. 6. The pattern 2 is rotatably mounted by spindles 38, 39 which can be moved in direction of arrow 44 so that saw 27 cuts the pattern. A stop 43 prevents the saw 27 from cutting completely through the pattern so that the two parts are joined by a bridge. This bridge is then cut through using a thinner saw blade so that two cylindrical bosses 8, 9 (Fig. 3) are formed on the faces 6, 7 of the pattern elements 2a, 2b. The toe portion 2a of the pattern is then placed in jig as shown in Fig. 7, the boss 8 engaging in a socket 46 in the jig to accurately position the pattern element 2a. The jig is used to hold the pattern element 2a while drills 47 and 57 form the bores 11 and 14. The heel portion 2b is then formed with the bores 12, 15 in the jig and the pattern is reassembled as shown in Fig. 4. The pattern is then used as a model in a copying lathe to shape a blank 20 to form the toe element 2a. The blank 20 is mounted in the lathe using a substitute component 10 (Fig. 5) whose length is adjustable to that of the missing heel element 2b. The single pattern is used to produce the range of sizes of the toe element 2a, and these elements 2a are then assembled with the mass produced heel elements 2b to form the lasts.

Abstract: 160,150. Peerless Baking Equipment Co., (Assignees of Denison, N. B.). March 12, 1920, [Convention date]. Combinations of interdependent valves. - In gas-burner apparatus, the gas-valve for the main burner is interconnected with a lift-valve for controlling the gas-supply to a pilot burner, the arrangement being such that when the main-valve is opened, the pilot valve is actuated to cause the pilot flame to be momentarily enlarged for igniting the main burner. The main valve 7 controlling the supply of gas from the pipe 10 to the burner 3 has a plug 8 with a slot therethrough and is operated by a rotatable spindle 9 which carries a sprocket-wheel 31. The sprocket-wheel 31 is connected by a chain 30 to a sprocket-wheel 29 carried on a spindle 20 which is provided with a suitable operating-handle. On the spindle 20 is mounted a cam 28 which operates the pilot valve 17, which controls the gas-supply from a pipe 15 to a pilot burner 13 situated so as to project its flame across the gas issuing from the main burner 3. The valve 17 comprises a tapered-plug normally resting on a conical seating, but is provided with a hole 19 which allows sufficient gas to pass to keep the pilot flame alight. When the spindle 20 is rotated to open the main valve through the chain 30, the cam 20 is rotated and momentarily lifts the pilot valve 17, causing the pilot flame to shoot out and ignite the main burner 3. In a modification, the sprocket-wheels 29, 31 and the chain 30 are replaced by bellcrank levers and a connecting-rod respectively.

Filed: 1974-06-14
Abstract: 1448044 Lamp failure alarms WELWYN ELECTRIC Ltd 14 June 1974 26498/74 Heading G4N An alarm device for detecting the failure of a lamp 5 in its energized or un-energized state comprises a magnetic former 1, a first winding 2 in circuit with the lamp 5, a second winding 3 supplying current pulses and a third winding 4 for detecting the amplitude of a voltage or current induced in it as a result of a change in amplitude of the flux density caused by the lamp failure. In the un-energized state of the lamp, pulses are induced in the loop including winding 2, lamp 5 and a capacitor 27. With a faulty lamp, the amplitude of variations sensed by the winding 4 is large as either the former 1 is no longer magnetically saturated or that the pulses provided by winding 3 are no longer opposed by those induced in 2 and this change is sensed by a pulse amplitude discriminator 9 for activating a warning lamp or a buzzer 10. As an alternative to using two formers for a pair of lamps, in the embodiment of Fig. 3 (not shown), the lamps are connected to a pair of windings having a common connection connected to the energizing source.
