Title: Improvements in apparatus for grinding and/or polishing glass, marble and like materials
IPC: B24B7/24
Filed: 1933-02-02
Abstract: 408,775. Grinding and polishing glass &c. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT, 75, Boulevard Haussmann, Paris. Feb. 2, 1933, No. 3207. Convention date, Feb. 3,1932. [Class 60.] In apparatus for grinding and polishing glass, marble &c. by means of rotary tools, means are provided for lifting and lowering the tools and for adjusting the pressure of the tools on the glass &c. A grinding head 1 acts on the glass v and is carried by a shaft 3 slidable in and rotated by a guide 5, and the shaft has at its upper end a ball &c. thrust 6 in a thrust box 7 having racks 7<a> on its opposite sides. The racks are engaged by pinions 8 fast with meshing gears 9, and on the spindle of one of the gears is a sprocket wheel 11, another and similar sprocket wheel 12 being mounted in bearings 16 and rotated, through worm gearing 13, 14 by a handwheel 15 or by power. Chains 18<a>, 18b pass round the wheels 11, 12 and have their ends connected respectively to a cylinder 19<a> and a rod 20<a>, and to a cylinder 19<b> and rod 20b, and between discs on the rods and the cylinder ends are springs 21, 22. By operation of the wheel 15 the wheel 12 may be revolved in either direction, thereby raising or lowering the shaft 3 ; when the tool 1 contacts with the glass, further operation of the wheel 12 compresses the spring 22 and applies additional load to the tool. This load may be indicated by a pointer geared to the spindle of wheel 11 and moving over a. dial geared to the spindle of wheel 12. In order to compensate for loss of pressure due to the wear of the tool, the spindle of one of the pinions 8 has thereon a sector 31, Fig. 7, carrying, by a cable 33, a weight 32, the sector being so shaped that as it moves due to the wear of the tool the lateral displacement of the weight balances the loss due to the wear. In a modification, the lifting and lowering and adjustment of pressure are effected by an electric motor, which drives a pinion meshing with one of the gears 9 through a torsion spring, the displacement of the ends of which is used to indicate the pressure applied to the tool. In a further modification, the lifting and lowering is effected by a screw connected to the thrust box and two sets of springs are employed, whereby the pressure on the shaft of the tool is obtained, the screw being moved by a nut rotated by worm gearing and driving other screwed spindles operating on one of the sets of springs, which is carried on the thrust box. In this modification, an indicating device also may be employed.

Title: Improvements in and relating to steam generators
Inventor: BELL ALAN
IPC: F22B1/08
Filed: 1961-01-30
Abstract: 929,682. Vertical steam boilers; superheaters. FOSTER WHEELER Ltd. Jan. 24, 1962 [Jan. 30, 1961], No. 3545/61. Classes 123 (2) and 123 (3). In a steam generator comprising a heatexchanger having a vertical cylindrical shell containing for the circulation of the heating fluid a vertical bundle of U-tubes connected to a pair of headers or a tube plate, the tube bundle is made up of two sections serving for the generators of steam and laying to either side of a central section which serves to superheat the steam and wherein the superheating section is isolated from the other sections and the walls of the shell by a trunking which defines a passage for the steam to be superheated. In the form shown the steam generator has a vertical cylindrical shell 10 having a water inlet 12 and a steam outlet 14. Within the shell there is a vertical handle 16 of U- tubes which are connected to a pair of inlet and outlet headers 18, 20 having connections 22, 24 passing through the shell and through which is circulated the heating fluid which may be the primary coolant from a nuclear reactor. The tube bundle 16 is in three sections, viz. two outer sections 34, 38 and a central section 36. The outer sections serve for the generation of steam and the central section for the superheating of this steam, the latter section being isolated by a trunking 40 which conforms with the shape of the U-tubes and provides a passage extending from the header 18 to the header 20. The tube bundle 16 and trunking 40 is surrounded by a baffle 26 which stops short of the bottom of the shell thus forming a downcomer 28 and a riser 30. The steam-water mixture generated within the shell is led by the baffle to steam-water separators 32 from which the separated water flows to the downcomer. Above the separators 32 steam driers 42 are arranged to discharge dry steam into a space 44 which is connected by a pipe 46 to the trunking 40. The steam then flows through the superheater in a counter-current direction to the heating fluid and leaves the superheater and shell through a pipe 14. The steam inlet end outlet pipes 46, 14 may lay inwardly of the baffle 26 as shown, or they may lay between the said baffle and the shell wall. The shell is protected from local overheating by the fact that the superheater tubes which are at a much higher temperature than the shell are completely isolated from the shell.
