Title: Improvements relating to the Destructive Distillation of Carbonaceous Materials.
Inventor: PERKIN FREDERICK MOLLWO
IPC: C10B1/04
Filed: 1917-06-11
Abstract: 114,937. Perkin, F. M., and West, J. June 11. 1917. Retorts, methods of working.-In order to obtain a higher yield of coal tar and of low-boiling aromatic hydrocarbons in the destructive distillation of coal &c., the distillation process is carried out in the presence of an inert gas such as coal gas or producer gas which has been stripped of aromatic hydrocarbons. The gas is introduced through pipes a, b into the coking-chamber c, and travels upwards through the red-hot coke in the lower portion of the retorts, whereby it becomes highly heated. It then passes through the partially coked mass from which it carries off the volatile matter, and finally through the coal which is receiving its first heat, the rate of travel of the gas being sufficient to prevent appreciable condensation of the volatile matter. The gas and distillates are then withdrawn through pipes d, e without meeting the coal in the feeding hopper.

Title: Improvements in or relating to the preparation of combustible materials
IPC: G01N25/22
Filed: 1923-03-26
Abstract: 219,059. Holmes, G. E., and Gas Light & Coke Co. March 26, 1923. Gas-mixing appliances.-The calorific yalue of gaseous fuel is controlled by burning a measured quantity in a calorimeter and automatically varying the composition of the fuel so as to maintain either a constant value or a predetermined alteration thereof. A mixture of coal gas and water gas from a main 10 is corrected for pressure and density before reaching a burner 25 at the base of a jacketed casing 28 containing baffle-plates 38 and a calorimeter capsule 35. The latter actuates a rod 36 attached to one arm 37 of a lever pivoted at 39 and carrying a recording-pen 42. The other arm 44 is connected to a bell 46 floating in liquid in a tank 48 and carrying a slide valve 23. The burner supply pipe 32 leads from the interior of the bell which receives the gas supplied from the main 10 after passing pressure regulators 57, 58. The bell having one surface exposed to the gas, and another surface exposed to the air, is sensitive to variations in the density of the gas. The composition of the gas is controlled by a valve 14 situated in the water gas main 13 and carried by a floating bell 15. The movements of the bell 15 depend upcn the admission or withdrawal of gas through a pipe 21 which connects the interior of the bell with the casing 22 of the slide valve 23; the casing also receives a pipe 62 connected to the main 10, and a waste pipe 61. The valve has a through-way to connect the opposed ends of the pipes 21, 62, and in the position shown the gas passes from the pipe 62 to the interior of the bell 15. The valve has also a cutaway part to connect, during downward movement, the pipes 21 and 61 and thereby allow the bell 15 to fall and vary the amount of water gas passing from the main 13 to the coal gas main 10. One or more auxiliary burners 60 may be supplied by the pipe 59, so that fluctuations in the heating value will more quickly produce an effect upon the capsule. In a modification, a throttle valve in the main 13 is coupled to one arm of a balance, the other arm of which carries a bell 15; and the bell may be operated by increasing or decreasing the amount of liquid in the tank. Specification 13292/15. [Class 55 (ii), Gas manufacture &c.], is referred to. Reference has been directed by the Comptroller to Specifications 13495/04, [Class 7, Air and gas engines], and 26961/04, [Class 55, Gas Manufacture].

Abstract: 814,501. Making girders and reinforcements; coiling. FRANTZ, R. March 18, 1957, No. 8788/57. Classes 83 (2) and 83 (4). [Also in Group X] A method of making a girder, or a reinforcement for concrete, of polygonal cross-section comprises unwinding rod or strip, passing it through straightening means, winding it over a polygonal-sectioned mandrel which rotates coaxially inside and relative to a cylindrical sleeve formed-with an internal helical groove, the groove guiding the rod in a helix on the mandrel, and then cutting the helix into sections to which longitudinal members are secured. Circular sectioned rod 1 passes from a spool A, through straightening means B through an opening 2 in a stationary sleeve F and around a triangularsectioned mandrel M, comprising three parallel rods, rotated in the sleeve F. An hydraulic head may be provided at the input end of the sleeve F to urge the rod 1 against the angles of the mandrel M. The sleeve F is formed with an internal helical groove which guides the rod 1 in a helix around the mandrel M as the latter rotates. A stop D controls shears C for cutting the wound rod T into lengths. Longitudinal members H are welded to the rod helix T by spot welding means operated in conjunction with a jig G moved in the direction f. The mandrel M may alternatively be stationary and the sleeve F and spool A and straightening means B rotated therearound. In this case the longitudinal members H can be welded to the helix T at the output end of the sleeve F as the helix issues therefrom. A triangular sectioned helix welded to two longitudinal rods and to a longitudinal U-sectioned member, Fig. 2, may be used as a flooring girder to be embedded in concrete. A beam, Fig. 3 (not shown), comprises a triangular-section helix welded to two angle bars and a rod. A helix of square cross-section is welded to angle bars, Fig. 4, to form a girder, or to rods, Fig. 5 (not shown), to form a reinforcement for concrete.

Filed: 1972-02-28
Abstract: 1376672 Closure applying machines ALUMINIUM CO OF AMERICA 28 Feb 1972 [1 March 1971] 9009/72 Heading B8T A capping machine includes a rotating turret assembly 10 with a frame 16 comprising peripheral vertical bars defining outwardly open vertical slots which receive a set of either roll-on 12 or swage-on 13, closure-affixing spindles, Fig. 8, which are interchangeable by removing gib plates (32), Figs. 4 and 7 (not shown), and changing the spindle in each slot. A roll-on process involves rotation around, and vertical motion relative to, the closure by the spindle, e.g. in applying a closure 42 and forming threads on it, and a swage-on process involves vertical motion only, e.g. in applying a crown closure 80. Verticle spindle movement is governed by two stationary cams 28, 18. Cam 28 controls the lowering of the spindle on to the container applying a downward pressure. Cam follower 52 is secured to the top of a yoke 46 resiliently mounted on roll-on spindle shaft 12. In the swage-on operation a section of the cam track is replaced so that the downward pressure is only applied for the shorter period required. Only roll-on spindle 12 has a cam-follower 64 for cam 18, the cam follower 64 being attached to the upper end of a slide 62 which has a downwardly tapered conical surface 69 at its lower end. As surface 69 moves vertically to follow cam track 19 rollers 63, 65 on headset 60 are pivoted in and out relative to the axis of the spindle, in order to deform the skirt of closure 42. This pivoting action is controlled by the rollers 67 at the upper end of the shafts 66 bearing against surface 69 as the headset rotates. The swage-on headset may include a pressure head and stripping means. Both types of spindles are free to move vertically being slidably mounted by means of ribs disposed in guide grooves in the edges of the bars in the turret frame 16. The drive means comprises a stationary gear 20 which drives a ring gear 24 via planetary gears 22 as they rotate with the turret frame 16 about centre support column 14. Ring gear 24 engages gears 59 providing the clockwise rotation of roll-on spindles 12, but does not engage the swage-on spindles 13. The roll-on spindles may be of the type which apply screw-on closures with pre-formed threads.
