IPC: F27B1/20
Filed: 1917-08-24
Abstract: 109,264. Steiger, A., and Steiger, W. W. Aug. 26, 1916, [Convention date]. Shaft kilns: charging.-Materials are fed to a lime or cement kiln through a centrally-arranged pipe or shoot 3, and are distributed by a cone 5 which directs the finer portion of the charge to the periphery of the kiln and the larger lumps to the middle. The cone can be adjusted vertically to regulate the feed, by the lever 9, and horizontally to vary the distribution, by screwed rods 13. The material, preferably in the form of blocks, is fed to the shoot bv a conveyer 16 delivering through a spring-controlled door 20, and the operation of the conveyer is governed bv a contact 18, according to the level of material in the shoot. The gases are withdrawn through a pipe 15 centrally arranged in the shoot 3. The head cover 2 is provided with doors 4 giving access to the upper part of the kiln. The upper end of the shoot is closed by a cover 19, and its lower part is formed with perforations 3<a>.

Abstract: 1427280 Retaining ring package and apparatus for the production thereof WALDES KOHINOOR Inc 21 March 1974 [10 July 1973] 12521/74 Heading B8C A retaining ring package comprises a plurality of retaining rings 10 which are arranged in a column and secured together by at least two pressure sensitive adhesive bands 16, 18 each of which extends outwardly from the inner edge of the exposed face of one end ring, along the column, and then inwardly to the inner edge of the other end ring. The bands 16 and 18 are diametrically disposed along the column and a third band may be adhered along the uppermost portions of rings in the column. To produce the packages a long banded column of retaining rings 10 is intermittently advanced along a rail 30a, over a gap 30g and along a horn 30b until it abuts against an adjustable stop plate 32. A vertically reciprocable push member 34 is moved downwardly to strip the rings, bridging the gap 30g, from the adhesive bands. Knives (38, 40), Fig. 12 (not shown), then sever the band portions bridging the gap 30g and pairs of thin flexible plates (42, 44) Fig. 10 (not shown) which are carried by the knives, fold the severed ends of the bands inwardly against the exposed faces of the rings located on each side of the gap 30g. The stop plate 32 is then lifted and the finished package on the horn 30b is discharged.

Abstract: 317,069. Hofmann, J. W., (trading as Hofmann, J. W., [Firm of]). Aug. 10, 1928, [Convention date]. Cable couplings.-Stranded conductors, such as aluminium or steel-aluminium cables, are connected together by clamps that engage the separate layers of wires. The outer layers of the cables d, e are successively removed so that each layer is exposed over a sufficient length to receive a pair of jaws a, b, c with clamping- screws f. The jaws a have adjacent recesses, at one side to fit the external layer of the cable d and at the other side to fit the centre layer of the cable e. The other clamps are correspondingly recessed. If both cables approach from the same direction two recesses of equal size are made in each clamp. Instead of separate clamps a single pair of clamping-plates having tapered recesses may be employed.

Title: Improved method of and apparatus for continuously impressing foils, webs or sheets of synthetic thermoplastic material
IPC: B29C35/08
Filed: 1952-05-23
Abstract: 719,964. Embossing. HIEDEMANN, H. May 23, 1952 [June 13, 1951], No. 13113/52. Class 100 (2). [Also in Groups V and XI] In a method of continuously impressing foils, webs or sheets of synthetic thermoplastic material the foil, web or sheet is hung freely substantially vertically over or below the gap formed by a horizontally disposed pair of impressing rollers and is passed through the gap substantially free of tension, and radiant heat is supplied to one or both sides of the foil, web or sheet, while hanging freely, to render it readily impressed on its passage through the gap. Before the web 1 passes between the impressing rollers 3, 4 it passes vertically upwards below the gap between the rollers and in doing so it passes through heaters 6. The heaters 6 are in a box 5 which may be run out sideways on rails 18, a slot 19 in the side of the box allowing it to pass the web. Each heater comprises a reflector 9 and a heating element 10 and is rockable about a pin 11, whereby the distances of the elements and the direction of the heat rays from them may be varied. Simultaneous rocking of the heaters is effected by levers 12, 13, 14 and a coupling rod 15. The rollers 3, 4 are slidable in a frame 20 and their position may be adjusted by members 21, 22.

Title: Improvements in or relating to the production of black colouring matter
IPC: C09C1/44
Filed: 1920-05-12
Abstract: 143,241. Poncelet, E. A. J. May 12, 1919, [Convention date]. Pigments.-Black colouring matter is prepared from graphitoid schists, such for example as are found in the Lion Mounttains, and which consist of black schists associated with black colloidal clay and iron pyrites by the following process. The mineral, after it has been allowed to react with the atmosphere to eliminate the sulphur it contains, is crushed in a mill and is then transferred to a vertical mixer in which a stream of water entering at the bottom and escaping from the top carries away the lighter black argillaceous matter and leaves the heavy schists, quartz, &c. behind. The suspension is then led to a " selector washing apparatus," which consists mainly in four cylindrical tanks beach fitted with a water supply e, under pressure. The suspended matter entering by pipe g tends to settle, but is met by the upward flowing stream from e, with the result that only the heavier particles fall through the bottomless cone d to the restricted passage c, whence they are carried to a settling tank. The finer particles pass through three other cylinders which are similar to the first but are successively wider and shallower. Leaving the last cylinder the suspension passes to a depositing tank and then to a long channel provided with a sluice valve. Finally the wash water is clarified and used again. The deposits from the last three cylinders b, after drying and grinding yield an impalpable mineral black, when passed through a fan separator. A black ochre is similarly prepared from the sludge deposited in the sluice channel. According to the Specification as open to public inspection under Sect. 91 (3) (a) of the Act, black pigments may be prepared by the above process from any material of similar composition. This subject-matter does not appear in the Specification as accepted.
Patent GB-132584-A (GB)
IPC: F28F13/12
Abstract: 132,584. Munro, H. Aug. 26, 1918. Baffles and partitions in tubes. -The tubes of heat exchangers, for example of boilers, are fitted with baffles which have wings a - - d substantially radial and parallel to the tubes and so connected by anglepieces e - - h or otherwise that compression is necessary to insert them in the tubes c<1>. The wings, during compression, are in contact along their central edges and divide the tube into substantially equal segments. In one modification, the angle-pieces are, flexible, and, in another, pairs of wings of V-section are used, united at intervals along their length, to effect the same purpose. One Provisional Specification describes baffles having hollows on their outer edges leaving a spiral path for the gases, and also slit on their outer edges to effect a better grip of the inner surface of the tube. The other Provisional Specification describes baffles made from a single plate corrugated longitudinally to a star or Z form, the provision of a stop on the baffles to prevent over-insertion, and the construction of radial winged baffles in which U-shaped portions are punched out from a bent strip forming two wings, a third wing being welded to the punchedcut parts. In this last modification, the V-portions may lie in recesses in the third wing to prevent obstruction of the passage of cleaning- tools.
