Title: Improvements relating to the annealing of wire and material of similar form
IPC: C21D9/54
Filed: 1922-06-01
Abstract: 202,443. Woodall, Duckham, & Jones (1920), Ltd., and Duckham, Sir A. M. June 1, 1922. Annealing metals; annealing-boxes.-Wire and like material is annealed by placing it in drums which are then rolled through a tunnel kiln out of contact with the floor thereof, the drums being provided at both ends with distance pieces which keep the drums from coming into contact with each other and ensure them rolling instead of sliding through the kiln. The wire in the form of coils is placed on the fixed mandrels of drums l which are rolled through a tunnel b, the latter being closed at each end by doors i and supplied through a port b<1> with heating gases from a producer g. Bosses n on the drums l roll on rails k, the drums being connected in pairs 'by distance pieces m which project beyond the drums and form buffers. When the wire is to be annealed in a neutral or reducing atmosphere the mandrels of the drums are perforated and filled with a reducing agent such as charcoal. The heating gases pass into a flue e whence they travel up a chimney f controlled by a damper f<1>; all or part of the heating gases may pass through an adjacent tunnel d containing a drying muffle c and pass away up a dampercontrolled chimney h. The muffle c is used for drying the coils after they have been pickled and washed, and contains guides o for the upper run of two endless chains which pass over sprocket wheels p, p<1> driven by suitable gearing.

Title: Temperature regulating circuits for soldering irons
IPC: B23K3/03
Filed: 1971-05-18
Abstract: 1401268 Automatic control of temperature WELLER ELECTRIC Ltd 23 May 1972 [18 May 1971] 15605/71 Heading G3R In a soldering iron temperature control arrangement the temperature of the soldering tip is sensed by a thermal switch 34 in the gate circuit of a controllable rectifier 17 in series with a heating element 30 of the iron. In operation, with the tip cold the switch 34 is open and current flows through the element 30 via R28, R20, R29. A control current is therefore available to gate SCR 17 ON during alternate half cycles when line 16 is positive with respect to line 24 so that the heater current will increase. When the tip temperature rises to a predetermined value the switch 34 will close reducing gate current of SCR 17 so that it will no longer be triggered ON. A reduced current therefore flows through the heating element 30 via the switch 34 and R28 so that the tip will cool. The cycle repeats and the tip will be maintained substantially at the predetermined temperature.

Title: Improvement in confection coating machines
IPC: A23G3/20
Filed: 1927-06-13
Abstract: 284,921. Marks, E. C. R., (National Equipment Co.). June 13, 1927. Coating bakers' and confectioners' goods. - Relates to a machine for applying a coating of finely divided solids, e.g. cocoanut, to confections to which viscous coatings have previously been applied, e.g., to biscuits having a marshmallow deposit therein and a coating of chocolate. The cocoanut is laid in a layer or blanket on an impervious belt 10, the biscuits are delivered on to the layer by the discharge conveyer h of a chocolate coating machine E, the tops of the biscuits are coated by a stream of cocoanut f from a hopper 46, surplus cocoanut falls on to a conveyer 13 and is spread into a uniform layer by a plough 15, the layer being transferred to the belt 10 by training the conveyer 13 around the roller 14 of the belt 10. The conveyer 13 leaves the belt 10 as the latter slopes upward to the point where the biscuits are received and a scraper 16 ensures that all the cocoanut is removed from the belt 13. The biscuits pass from the coating conveyer 10 to a pervious conveyer 11 which is agitated as described in Specification 203,915, and has a lower course, returning in a shoot 12 inclined downwardly towards the plough 15. The cocoanut shaken from the biscuits is moved down the shoot 12 by the belt 11 and is deposited on to the belt 13. The plough 15 is supported by links 59 and bell cranks 60, 62 engaged by a screwed rod 63 which is revoluble to adjust the level of the plough and consequently the thickness of the layer. The belt 13 is supported adjacent to the plough by a platform 57 carried on cross rods 58. The plough is vibrated bv crank means. The cocoanut which is pushed over the sides of the belt 13 by the plough falls through a shoot 72 on to a surface which is traversed by scoops 79 mounted on endless chains, the scoops passing over the hopper 46 which is thereby replenished. A corrugated roller 49 revolves in the outlet of the hopper 46 and is scraped by a member 50. An adjustable pivoted gate 51 regulates the quantity of cocoanut discharged. The biscuits are deposited by the conveyer 11 on to trays, comprising frames t and screens s, placed by hand on a conveyer 100 disposed partly beneath the lower course of the conveyer 11. The apparatus is driven from the coating-machine E through connecting shafts and worm, sprocket and other gearing. Belt-tensioning means are provided, the belt 10 being tensioned by a roller 26 on a frame 27 pivoted at 28 and adjusted by a screw 29. A drip pan p underlies a part of the belt h to prevent the chocolate from dripping on to the cocoanut layer. The apparatus is preferably portable and is thus mounted on a wheeled frame 18, and the conveyer 100 is adjustable in inclination, being pivoted at one end on the shaft 96 and adjustable at the other end by the strut 102.

Title: Method of and apparatus for melting refractory material
IPC: B01J6/00
Filed: 1952-06-24
Abstract: 716,266. Melting-furnaces.' BABCOCK & WILCOX CO. June 24, 1952 [July 17, 1951], No. 15900/52. Class 51 (2). [Also in Groups V, XI and XXXVII] In an apparatus for making refractory materials (see Group V) there is provided a heating chamber, fuel burning heating means arranged to heat the chamber, a conveyer arranged to feed the refractory mixture into the chamber where the temperature is elevated to a value approaching its melting temperature but below its sticking temperature, an electric arc furnace (see Group XI) and means operable to discharge the thus heated mixture from the chamber into the furnace for melting. As shown the starting materials e.g. raw bauxite and raw kaolin are fed from a storage bin 10 into a dry mix conveyer 11, and then to a mixer 12 where water is added and the mixture is then discharged into an auger 13. which extrudes a column of material-which is fed to a conveyer 14 and cut into cubes which are fed to an elevator 15, from the upper end of. which the cubes arc discharged into a spout 16 leading to a spout 17 feeding a fuel fired rotary kiln 20 having a stationary burner hood 21 at the material exit end provided with a fuel burner 22 for combustion of gas oil in the presence of air supplied by a blower 23. The cubes are continuously fed to and through the kiln 20 in intimate admixture with the high temperature products of combustion from the burner flowing through the kiln 20 to the exit of stack 24, a separating chamber 25 being interposed in the gas flow path for recovery of any entrained material which may be periodically discharged for re-use from a hopper 26. The highly heated material is continuouslydischarged from the burner and kiln 20 into a storage hopper 30 suitably insulated to hold the material at or near the temperature reached in kiln 20 and lined with firebrick or other refractory 32 and through a swing- ing door 35 at the bottom of hopper 30 into the electric rocking furnace 50 or through a byepass chute 40 controlled by a gate 34 if electric heating is not required. The rocking furnace 50, Fig. 3, is lined with cooling tubes 66 arranged in two separate sections and during operation is rocked through an arc equal to 360 degrees less the arcuate extent of a charging door 63 and adjacent discharge spout 64. The cooling tubes 66 are initially covered with a lining 70 of the material to be melted, the thickness of which is maintained by freezing of the molten charge as the furnace is rocked. Variations in thickness of the lining are detected by an integrating meter receiving measurements of the rate of coolant flow through the tubes 66, and of the inlet and outlet temperatures of the said coolant. In the furnace 50 the temperature of each batch of material is raised from approximately 2800‹ F. to 3400-3450‹ F. to melt the material when it is discharged into suitable moulds to form solidified pigs of mullite. Specification 716,265, [Group V], is referred to.
