Title: Improvements in and relating to hollow beams for use in furnaces
IPC: F23M5/06
Filed: 1930-06-06
Abstract: 354,907. Furnace linings &c. KARRENBERG, G., 51, Machabõestrasse, Cologne, and RÍMER, H., 19, Engerstrasse, Dusseldorf, both in Germany. June 6, 1930, No. 17578. [Class 51 (i).] Linings; roofs; grates; steam-generator furnaces ; stoking.-Relates to the protection by refractory coverings of air or watercooled beams or tubes which are either wholly or in part exposed to high temperatures and consists in providing carriers embracing the beam and each holding a number of separate bricks. The invention is particularly applicable to a peat-burning furnace, Fig. 22, in which relatively long beams 44, 45 etc. have to be carried right across the width of the furnace without intermediate support, the beams 44, 45, 46, 47, 52, 53 defining the lower part of the fuel supply shaft and the beams 65, 11 serving respectively as scraper for the travelling grate and combustion-gas baffle. In one form of which Figs. 1, 2, and 3 are examples, the beam consisting of two U-section members 1 is surrounded by the metal carrier 2 in two parts united at a top by a dovetail plate 3. The carrier has inwardly bent flanges 4, except at the top, where they are vertical, Fig. 3, and in use bricks 5 with undercut heads are slid in first and finally a closure brick 6 dropped in at the top between the vertical flanges. In a second form, Fig. 5, for a unitary beam 1, the carrier comprises a flat-topped part 8 with inwardly bent flanges from which hangs the remaining part, made in two members 2 hooked together at the bottom. In this construction the closure bricks 6 are also of dovetail form and are slid into place laterally. A rib 7 prevents lateral displacement. For beams of circular section constructions somewhat similar to that last described may be adapted ; or that shown in Fig. 8 in which the carriers are relatively thin rings widely spread, In a further modification, of which Fig. 14 shows an example, the carrier 33 only partly surrounds the beam 32 but in addition extends to a wall-plate 34 thus enclosing a hollow air passage. The carrier is supported from a U-beam 36 either bya bolt connecting its ends, or, as shown, by hook members 35, 39. In a similar modification, applicable to beams such as 44 &c., Figs. 18 and 22, the circular beam, U-shaped brick carrier and the supporting girder, such as 36, are connected together by a diametral bolt 48 and tube, &c. Somewhat similar constructions are adapted to the beams 52, 65, the latter in a modification comprising two circular beams adjustably connected together and supported in adjustable position over the grate by a horizontal water-cooled tubular stay (not shown) in conjunction with a hanging link 71 adjustable vertically from outside the boiler by motor-driven screw-and-nut gearing. The water supply to the hollow beams may be boiler feed water.

Abstract: 462,098. Gun mountings. CESKOSLOVENSKA ZBROJOVKA AKCIOVA SPOLECNOST BRNO. June 24, 1936, No. 17587. Convention date, June 24, 1935. [Class 92 (i)] [Also in Group XXIV] Means for driving the elevating and traversing mechanisms of guns consists of two driving friction wheels 6, 7, driven by a motor 1 and two driven friction rollers 10, 11, which are displaceable diametrically over the faces of the driving wheels and are drivably connected with the traversing and elevating mechanisms, respectively, the speed and direction of such movements being controlled simultaneously but independently by a common controlling device. In the construction shown, the friction wheels consist of two spring-pressed plates 15, 16, mounted on two meshing bevel wheels 3, 4, and the rollers 10, 11 are axially slidable on shafts 20, 21, to which they are keyed by splines. Axial adjustment of the roller 10 is effected by a lever 39 which is journalled on a tube 25 connected to an exterior casing 26, and which engages at its forked end 30 in a groove in the extended hub 31 of the roller. The upper end of the lever is also forked and embraces the lower arm 38<1> of the control lever 38 which is pivoted thereto at 32. The arm 38<1> carries a toothed segment 35 which meshes with circumferential teeth formed on the hub 37 of the roller 11. The lever 38 can thus control the movements of both friction rollers, the shafts of which carry toothed wheels for transmitting movements to the traversing and elevating mechanisms. Means may be provided for depressing the plates 15, 16, so that the shafts may be rotated by hand. The control levers may be operated from a distant observation station.

Abstract: 790,480. Grinding. BRITISH CAST IRON RESEARCH ASSOCIATION, and CONSOLIDATED PNEUMATIC TOOL CO., Ltd. Oct. 18, 1955 [July 18, 1954], No. 18042/54. Class 60. [Also in Group XXVIII] In a grinder the grinding wheel 1 is porous and is mounted on a shaft 2 having a longitudinal bore 6 which communicates at one end, through a radial port, with the interior of the wheel hub and at the other end, through another radial port, with a cavity 17 in a housing, the cavity 17 constituting or communicating with a source of supply of coolant liquid for the wheel to suppress dust. The grinder is portable, the shaft 2 being driven from a built-in air or electric motor or through a flexible shaft from a fixed power input ; the shaft 2 rims in a sleeve 3 which provides a hand grip and which is supported from the frame of the machine, the latter carrying a cowl normally enclosing about one-half of the wheel. A two-part housing 11a, 11b surrounds as a good running fit, a bush 12 secured, as a snug fit, on the shaft 2 ; the housing part 11b is screwed into the end of the sleeve 3. The rear end of the bush 12 abuts the inner race of a ball bearing 13 housed in the end of sleeve 3, seepage from the housing 11a, 11b along bush 12 into bearing 13 being prevented by a helical groove 14 in the bush. The housing parts 11a, 11b are connected by screw-thread 16 leaving an annular cavity 17 which is enlarged around the bush 12 by recesses 18, 19 containing resilient gland washers 20, 21. An inlet port 24 in the outer annular wall of the housing part 11a communicates with a connector 25 for a water pressure line. The shaft 2 and bush 12 have a radial duct 22 and a port 23 in register, the duct 22 opening into the bore 6. A radial duct 27 in the shaft 2 registers with a port 28 in the bush 29 of the wheel 1, the latter having its central bushed hole enlarged at 30 to form an annular cavity in which the water collects prior to passing outwards to the working face of the wheel through the pores. By reducing the head of water at the input to a very low value the flow can be made dependent on the rotation of the wheel so that liquid is flowing when the wheel is rotating and not flowing when the wheel is not rotating.

Abstract: 500,187. Preserving rubber. WING- FOOT CORPORATION. June 29, 1937, No. 18050. Convention date, Nov. 5, 1936. [Class 70] [Also in Groups IV and III] The deterioration of rubber and the similar deteriorable organic materials balata, guttapercha, synthetic rubber, 'reclaimed rubber, and latex, is retarded by the addition of the reaction product of a hydrogenated aryl naphthalene and a ketone. The reaction product is a complex mixture which may be used as such or which may be subjected to an acid treatment before use. It is found-that the acid treated materials possess superior antioxidant properties. The treatment preferably consists of a washing with hydrochloric or another mineral acid. The acid treatment usually changes the viscous liquid reaction product into a thick tar. Suitable hydrogenated aryl naphthylamines mentioned include phenyl AR tetrahydro-alpha-, and beta-naphthylamines, AC tetrahydro-alphanaphthylamines, and beta naphthyl-AR-tetrahydroalpha-naphthylamine. Suitable ketones mentioned include acetone, methyl ethyl ketone, mesityl oxide, diacetone alcohol, acetophenone, benzophenone. and dibutyl ketone. In examples, (1) AR - Tetrahydro - beta - naphthylamine and acetone are heated for 14 hours at 195-210‹ C. in an autoclave in the presence of a small amount of hydriodic acid. The product is distilled at 115‹ C. under 13 mms. of mercury, and the residue forms the anti-ager. (2) The material obtained according to example (1) is treated with hydrochloric acid, and the thick tar which results is washed with dilute caustic soda and then with water. (3) Phenyl- AR - tetrahydro - beta - naphthylamine and acetone are reacted and worked up as in example (1), and then acid treated as in example (2). Tables are given to show the efficiency of the anti-oxidants of the present invention when incorporated in a standard rubber mix. The anti-oxidants mav be used either alone or in conjunction with vulcanizing agents, accelerators, pigments, and fillers.
