Abstract: 1489648 Coal drying and coke quenching plant BABCOCK-BSH AG 1 April 1975 [1 April 1974 11 Nov 1974] 13297/75 Heading C5E In a coking plant in which coal is continuously dried and preheated by utilizing the sensible heat of the hot coke, the drying gas circuit includes means for extracting water vapour absorbed by the gas during drying of the coal, these means including condensers situated in the gas circuit downstream of the coal drying and preheating apparatus and before the reheating apparatus. The plant may have separate circuits for the coke quenching gas and the drying gas, the drying gas circuit including the secondary side of a heat exchanger which, on the primary side, is a part of the quenching gas circuit (Fig. 1, not shown). In this embodiment, the plant may include a hot gas generator leading to the primary side of the heat exchanger for use when starting up the plant when no hot quenching gas is available, or to supplement the hot quenching gas (Fig. 3, not shown). In a second embodiment (Fig. 2, not shown), the drying gas and quenching gas are combined in a single circuit which includes an after burner combustion chamber through which the hot gas from the quenching chamber is conducted before contacting the coal. This ensures that any water gas generated by contact of the gas with the hot coke is combusted and no enrichment of the circulating gas occurs. In both the embodiments described, separate dryer and preheater stages are provided, connected in counterflow series arrangement, and the drying gas circuit contains a line connected parallel to the preheater and feeding directly to the dryer an additional portion of gas which has not first passed through the preheater.

Title: Improvements in the manufacture of axial compressor rotors
Inventor: NICHOLS CHARLES ALVIN
IPC: B23P15/00
Filed: 1955-05-09
Abstract: 770,120. Making blade discs for axial compressors; turning. GENERAL MOTORS CORPORATION. May 9, 1955, No. 13328/55. Classes 83 (2), 83 (3) and 83 (4). [Also in Group XXVI] Forging. A blade-wheel of an axial compressor is made by forming an over-size wheel rim 16, Fig. 5, having an internal annular groove 24, locating a disc 14 within the rim with the periphery of the disc aligned with the groove and mechanically contracting the rim on to the disc so that the periphery of the latter is gripped within said groove, Fig. 6 (not shown). The disc 14 is made of a low-alloy steel, preferably from cross-rolled stock, and its side walls are machined to conical form. The disc is then heat-treated and finish-ground. The rim 16 is made of stainless steel rolled into a hoop and welded. The groove 24 is machined therein and the rim is heat-treated and ground. The rim 16 is then located in the conical bore of a die 26 and the disc 14 is positioned therein. A collapsible pressure-block 30 is located on the rim and the latter is then forced through the die to contract the rim by a ram 28. The contraction of the rim will produce a predetermined buckling of the disc 14, Fig. 6 (not shown); this buckling will disappear when the rim and disc are removed from the die. The wheel-assembly is then pressed between a pair of dies 36, 38, Fig. 7, whereby the walls of the groove 24 are swaged round the bead 22 at the periphery of the disc. The wheel is then placed on a rotatable indexing-plate and a series of notches 42, Fig. 10, are stamped into the side of the rim by a punch 44, Fig. 8 (not shown). The contracting, swaging and notching operations are preferably performed cold. Spacers 12 rolled from strip-stock and welded into hoops have their edges notched by broaching or shearing to correspond to the notches 42 in wheel rims 16. Dove-tail slots 46, Fig. 11 (not shown), are formed in the periphery of the rim 16 for receiving the blades, subsequent to the notching operation. A compressor rotor assembly, Fig. 1, comprises a series of wheels 14, 16 with their blades 18 mounted on a tiebolt 8 with intermediate spacers 12 between the wheels. The spacers 12 having notched edges engaging in the notches 42 in the wheel rims, enable the drive to be transmitted directly between the rims of adjacent wheels. The blades 18 are retained in their slots in the rims 16 by pins 20. Turning. The conical side-walls of the disc 14, Fig. 5, are formed by flexing a flat disc against a concave block which is then rotated whilst a cutting tool traverses the disc radially of its axis of rotation. Upon the disc being released from the block it will spring back to its original plane, thus revealing a conical surface, and the operation is repeated on the other side.

Abstract: 109,657. Hadfield, G. H., and Bawtree, A. E. Sept. 21, 1916. Coating processes varnishes.-Surfaces coated with a composition containing Chinese wood oil, linseed oil or other drying oil are treated at temperatures not exceeding 120‹ C. with nitric acid vapour, sulphur dioxide, or an equivalent vapour or gas in order to effect crystallization, coloration, or hardening. The following varnishes are described, viz. : resin, Chinese wood oil, linseed oil and turpentine; Congo gum, Chinese wood oil, and petroleum spirit of 75‹ F. flash point; and Congo gum, Chinese wood oil, and turpentine of 35‹ C. flash point. The surface may be exposed to the action of another vapour, or gas such as air before, during, or after the treatment. Local effects may be obtained by coating parts of the surface with a varnish high in gum and then the whole surface with a similar varnish lower in gum, the vapour treatment then causing the parts which have received the two coats to dry glossy while the remaining parts will dry crystalline. When it is desired to avoid any coloration nitric acid is used cold, and any other gas employed in addition is freed from sulphur dioxide by means of lumps of slaked lime or pieces of pumice containing solution of alkali such as washing soda. Specifications 10361/10 and 26029/11 are referred to.
