Title: Continuous Process for Simultaneously Producing Coke and Carbon Black.
IPC: C09C1/50
Filed: 1968-07-12
Abstract: 1,172,636. Making coke and carbon black. PEABODY COAL CO. 12 July, 1968 [11 Dec., 1967], No. 33493/68. Heading C5E. [Also in Division C1] Coke and carbon black are produced simultaneously by continuously feeding a flat coal bed through a carbonizer for partial combustion with air to produce partial coking, reaction of the air with part of the hydrocarbons, and cracking of unreacted hydrocarbons, to form carbon black which is carried by the combustion gases via 64 to a filter 68 where it is recovered. Coking is completed in a shaft furnace. The pressure in the carbonizer must be controlled by a damper 70 so that it never falls below 0 inches of water, thus preventing the ingress of air and burning of carbon black. A pressure of 0À05 to 0À1 inch of water may be maintained. Air for combustion is preheated at 36 by gases from 32, 34 which pass to the cooler 28 via 38, 42. The heated air is delivered to separate zones in the carbonizer (see Fig. 2, not shown).

Illumination, changing advertisements by controlling. - A series of figures 4 on a background 2 are made visible in turn bv the successive illumination of lamps 6 located one above each figure. The figures and background are continuously illuminated bv lamps 8 emitting light of such a colour that the figures are indistinguishable from the background, while the lamps 6 are of a colour which causes the figures to be seen clearly. The lamps 6 may be shielded by reflectors and are lit by a rotary switch 17 engaging contacts 15 which may vary in length to determine the period of lighting of each figure. A sign 5, in colours which allow it to be seen when illuminated by either lamps 6 or 8, may be arranged below the figures 4. The device may give a kinematographic effect, or may be applied to the spelling of a word letter by letter and the, subsequent illumination of the whole word. In a modification the figures are formed as transparent portions in coloured translucent panes which cover the front of compartments arranged side, by side and each illuminated by an internal and an external lamp of different colours. Specifications 313,457 and 313,458 are referred to.

Title: Eccentric mechanism for vibratory apparatus
IPC: B06B1/18
Filed: 1972-07-18
Abstract: 1351432 Road and like rollers A-T-O Inc 18 July 1972 [13 Aug 1971] 33579/72 Heading B7H [Also in Division F2] An eccentric system for a vibratory apparatus for use in an earth compacting roller comprises a tube 28 having end closures, not shown, supported in bearings for rotation about its axis, and an eccentric bar 36 extending longitudinally and spaced radially inwardly from the tube 28, the eccentric bar 36 having ends coaxial with the tube 28 and carried by the end closures of the tube. The tube 28, its end closures and the eccentric bar 36 constitute an eccentric shaft which, together with its bearings, is enclosed by an outer housing 20. The housing 20 is disposed coaxially within the roller 10, and is rigidly connected at its ends to the roller headers 12 and stub shafts 14. Impellers at the ends of and rotatable with the eccentric shaft circulate a lubricant, such as oil, between the interior of the tube 28 and the outer housing 20 by way of the bearings, thereby lubricating and cooling the bearings continuously. Air in the structure is also circulated through the bearings by the impellers for cooling purposes. In addition to the oil flowing through vents 52 provided with ports 54 in the tube 28, some oil enters a longitudinal tube 51 through central inlets and flows to small metering outlet ports in the end plugs of the tube 51 via filtering material such as stainless steel wool. Solid contaminants in the oil are normally held against the tube 28 by centrifugal force, but any that do enter the tube 51 are filtered out before reaching the metering outlet ports. The roller 10 may be filled with water ballast to increase its weight. If complete filling of the roller is not required, a water cooling effect can be achieved by means of scoops (Fig. 4, not shown) secured to the inner surface of the roller, adjacent ones of which face in opposite directions. With this construction, the roller may contain a small amount of water which the scoops pick up and drop onto the housing 20 for either direction of roller rotation. The shaft 26 formed by the combination of the tube 28 and the eccentric bar 36 is driven by a coaxial drive shaft (not shown) having a splined connection to one of the end closures 30 of the tube 28. The drive shaft is suitably rotatably mounted within the corresponding roller stub shafts 14, and is equipped at its outer end with a drive sheave.

Abstract: 637,841. Shearing. UNITED ENGINEERING & FOUNDRY CO. Dec. 22, 1947, No. 33788. Convention date, Nov. 9, 1940. [Class 83 (iv)] Straightening.-In a reciprocating blade flying shear, the upper blade 6 is carried on a frame 5 reciprocated by an eccentric 3 on a drive-shaft 15. The lower blade 9 is mounted on a carrier 8 guided in the frame 5 and reciprocated by a cranked portion 1 of the shaft 15. The frames are swung about the shaft 15 by rods 22 oscillated by cranks 24 on a shaft 25. To allow for variation of stroke of the frame to provide non-cutting strokes an eccentric 36 rotated from a shaft 44 is interposed between the frame 5 and the crank 1. When the shafts 15, 44 are rotated with the eccentric 36 in the setting shown in Fig. 1, cutting takes place with the cutters moving in closed paths. When the eccentric 36 is rotated the throw of the crank 1 is periodically reduced to prevent shearing. The mechanism is driven by an electromotor 16 through change-speed gearing. The sheets are fed from a roller leveller R and on guide 12 and are fed away by a belt 28. U.S.A. Specification 1,973,515 is referred to.

Abstract: 1,094,202. Hollow articles by injection/blowmoulding. E. I. VALYI. Aug. 10, 1965, No. 34234/65. Heading B5A. In an injection/blow-moulding process, hollow articles of organic plastics material having a neck opening are made by injection-moulding a parison, with one open end and a neck portion at the other, removing the parison to a blowmould, and blow-moulding it while confining the neck portion to retain fluid-pressure and then removing the confining-means from the neckportion. The confining means may be a neckring and may be internally threaded so as to form a thread on the exterior surface of the neck-portion from which it may therefore be unscrewed. The parison may be formed on a blow-core, e.g. by passing the plastics material through the neck ring into the parison die cavity, which may transfer it and the confining-means, the latter at least partly magnetically from the parison die to the blow-mould. The confining means may be removed after blowing, cooled, and is preferably returned to the parisonmoulding die. The neck may be punched through to form the neck opening. Two neck rings may be used, one disposed in the parison die while the other is in the transfer position.
