Title: Coil transporting apparatus particularly for use with coil forming, compacting and tying machinery
IPC: B21C47/24
Filed: 1967-06-09
Abstract: 1,147,097. Coil forming and binding apparatus; reciprocating conveyers. MORGAN CONSTRUCTION CO. 9 June, 1967 [22 June, 1966], No. 26807/67. Headings B8A and B8C. [Also in Division B3] Apparatus for transporting coils, e.g. of metal rod, from a forming station to a compacting and binding station includes a mandrel raisable through a slotted floor to support the coil during formation and to transport the coil along the floor towards the binding machine, the mandrel then withdrawing beneath the floor to return to the coil forming station. In one arrangement, a pair of mandrels 56, 78 are vertically reciprocable on carriages 40, 70 respectively, the carriages moving on a track 36. The carriage 70 also carries a pusher 112 which may be elevated through the slot in the floor 14 by linkage and piston and cylinder means 114a, 114b, 115. The carriage 40 oscillates between a coil forming station A and an intermediate station B, and the carriage 70 between the station B and a binding station C. As the carriage 70 moves to station C, the pusher 112 moves the bound coil at the station to an intermediate position D. A retractable arm 120 on a carriage 117 draws this coil on to a conveyer at station E. Coil forming and binding.-Coils are initially formed on a plate 26 when the latter is in its advanced position 26a within an open, fronted guide 18. When the mandrel 56 rises within the guide, the plate withdraws allowing the coils to drop over the mandrel and continue to build up round it. The plate returns when the coil is complete and may include shear means to separate the coil from the supply. At station C two bands are applied at 180 degrees. The mandrel 78 remains within the coil during binding and includes side grooves to receive portions 104b of guide tracks 106 on elements 92, 94. These descend to embrace the coil after the latter has been compressed, having first pivoted from the dotted inoperative positions shown in Fig. 4. Compression is produced by plates 96a, 96b which descend on either side of the mandrel. The tracks have hinged portions 107 which close to complete the circuits when binding is carried out by known means (not detailed). Alternative arrangement.-In order that the coils should be formed to a greater extent on the mandrel 56, the latter may be duplicated, each such mandrel being mounted on a separate carriage on either side of the machine centre line, Figs. 11, 12 (not shown). These mandrels are capable of passing each other and while one is feeding forward a coil to station B, the other is returning to station A.

Title: Thermal processing apparatus
IPC: C10G9/20
Filed: 1947-10-08
Abstract: A furnace for the controlled thermal-treatment of fluids, particularly the pyrolysis of hydrocarbons, wherein there is countercurrent flow between the fluid and hot combustion gases, comprises a bank of convection-heating tubes disposed in the flue gas passageway, the fluid inlet being connected to said convection tubes, a bank of tubes arranged on the walls of the combustion chamber, and an arch in the combustion chamber having a refractory, radiant-heat emission surface on to which the flames from adjustable burners are directed; the curvature of the surface being such that the first tubes in the combustion chamber to be traversed by the fluid, are subjected to solid-body radiation. The radiant tube bank may pass into a wholly or partially shielded tube bank where the rate of heat absorbtion is reduced but the conversion temperature is maintained. The combustion gases may be reduced in temperature before they pass over the convection-heating tubes.  The pyrolysis of light hydrocarbons to olefins is referred to.  The furnace shown has a combustion chamber 10 longitudinally divided into two sections by hollow arch 12 which is faced with refractory material.  Each face of the arch is exposed to flames from a row of burners 25 which are supplied with fuel and primary air through mountings 26 and are adjustable as to flame length and direction.  Secondary air admitted through inlets 15 and 16, Figs. 2 and 3, is heated inside the arch and then passes through opening 20 and ducts 21 into burner-openings 23.  A bank of horizontal tubes 30 joined by headers 31 is disposed along each of the side walls 5 and 6 which converge at their upper ends to connect with flue gas passageway 9. Convection tubes in two sections 34, 35 are disposed in passageway 9, and are supplied by feed-lines 36, 37.  The outlets of tube-sections 34 and 35 are connected to the right and left-hand radiant tube-banks respectively. The faces of the arch 12 are curved in such a way that a high heat input is given to the fluid while it is in the upper and middle tubes of each bank of radiant tubes 30, and thermal conversion of the fluid takes place therein.  The lower tubes of each bank are shielded from direct radiation by walls 33, and are provided to complete the conversion.  The pyrolysed products are dis <PICT:0654670/III/1> <PICT:0654670/III/2> <PICT:0654670/III/3> charged through lines 40, 41.  A bank of tubes 45 supplied with steam through pipe 46, is disposed at the outlet of the combustion chamber, and reduces the temperature of the flue gases before they pass over the convection tubes.  The superheated steam leaving tubes 45 through pipe 47 may be supplied with the process-fluid to feed-lines 36, 37.  The tube headers 31, Fig. 2, are disposed in boxes 50 having doors 51, there being circumferential spacing between each tube 30 and the wall 52 of each box.  In a modified arch (not shown), air is supplied to the interior of the arch through a duct extending upwardly through the setting to a substantial height within the arch.

The upper and lower punches 20, 21 of each pair co-operate with moulds 22 through a stationary upper cam track 23, Fig. 2, and compressing roller 25 and a lower track 24 and roller 26. In the cycle of operations, the punch 21 on leaving cam 24 is lowered to open the mould and the powder fills in, the punch rising again on meeting a weight-adjusting cam 40 which removes excess of powder, next both punches strike rollers 25, 26 and the powder is compressed to a tablet, the tablet is then raised out of the mould and leaves by a discharge shoot 37. The feeding grid 27 receives powder from a hopper 29, and is subdivided by walls 127, Fig. 3, having staggered apertures 128, the material being moved back and forth over the moulds above which a surplus is always maintained, the surplus in the mould and excess powder placed in the grid being removed by a scraper 129 attached to the grid and pressed on to the mould table by a spring 130. The grid 27 is supported slightly above table 30 by adjustable bolts 32, the space between being varied according to the nature of the material being compressed. To enable the grid 27 to be readily adjusted and removed, each bolt 32 screws into a cap 25 which is externally threaded to screw into a support 36 on fixed table 13. Thread 32<a> on bolt 32 is of the same or finer pitch than, and is cut the same hand as the thread 35a on the exterior of cap 35. The bolt 32 is secured in a lug 33 on the grid by a lock-nut 34. This supporting means enables the grid to be removed from position and replaced without altering its adjusted position relatively to the moulds. Dust from table 30 and from a flange 81a of the bearing 81 for the lower punches, which underlies and is less in diameter than table 30, falls on an inclined portion 82 of a housing surrounding the machine, and is removed. Specification 461,854 is referred to.
