Title: Improvements in or relating to the conditioning of gases, particularly air
IPC: F24F3/12
Filed: 1939-02-02
Abstract: 512,229. Conditioning air. LODGE-COTTRELL, Ltd., (Research Corporation of New York.). Feb. 2, 1939, No. 3571. [Class 137] Air is conditioned by adjustment of its temperature and humidity and by removal of suspended particles of dust or mist, the air being brought into contact with an extended surface of hygroscopic liquid maintained at a constant temperature and then subjected to the action of a high tension electrical field. The air enters a casing 10 by an inlet 11 and passes up tubes 20 in each of which is a discharge electrode member 14, each tube providing a complementaryextended surface electrode for the collection of particles precipitated from the air. A solution of calcium chloride is circulated by a pump 25 from a sump 13 to a reservoir 22 and overflows over the inner surfaces of the tubes 20. Cooling water from a pipe 27 flows through a cooling jacket 26 and through the space surrounding the tubes 20 thus maintaining the hygroscopic liquid at a predetermined temperature. The concentration of the hygroscopic liquid is maintained constant by suitable control means. In modifications the electrostatic dust precipitator is separate from the humidity control as in Fig. 3, in which the gas first passes through staggered baffles 41 on to which is delivered the hygroscopic liquid from sprays 40. The entrained liquid carried by the air is precipitated on the inner surfaces of tubes 42.

In the arrangement described, the part of the series passing across the outlet from the casing is energized and moves upwards after passing through the bath. The other flight is disconnected from the source of voltage and functions as a preliminary mechanical filter. A pre-ionizing element may be mounted in the casing between the two flights of plates, and comprises a series of vertical flat bars 26 connected to earth, and intermediate thin wires 27 connected by brackets 28 and cross-bars 29 to a frame 30 and to a source of high potential.

Title: Tapered tube making device and method therefor
IPC: B21C37/18
Filed: 1967-01-02
Abstract: 1,139,283. Making tapered tubes; bending. V. BOBROWSKI. 27 Jan., 1967, No. 4174/67. Headings B3A and B3E. A tapered tube is formed from a planer blank by passing the blank through a succession of forming stages each including a plurality of rolls which move apart as the blank passes through to accommodate the increasing dimensions of the blank. A tapered blank 34 is fed by roller means 44 between guide plates 68 to a first forming stage comprising upper rollers 53, Fig. 10, and lower rollers 57 which co-operate to form a flange 38, Fig. 3, in the blank. As the blank passes between the rolls the rolls 53 are moved apart from one another by the rotation of their threaded shafts 51 and the rolls 57 by their shafts 55. After the blank has passed through, the rolls are returned to their initial position by opposite rotation of their shafts. The shaft drive is controlled by micro-switches engaged by the blank. Further flanges 39, 40, Fig. 5, are formed in two succeeding forming stages, the central planer section 73 of the blank being guided between stages 1 and 2 and stages 2 and 3 by rolls 74. The final bend 41, Fig. 6, in the centre of planer section 73, is initially formed by rollers of an intermediate stage 83. The blank then passes between inclined rollers 91, moved apart as the blank passes therethrough to rollers 103, 104, 106, Figs. 14, 18, moved apart vertically as the blank passes therethrough. The blank then passes between horizontal rollers 113, 115, vertical rollers 118, horizontal rollers 157, 158 and diagonal rollers 171, the tube being supported internally by an anvil 109. The rollers are suitably moved apart during passage of the blank and the seam is welded by means 170. The tube is finished by passage between lower rolls 187 and upper rolls 188, Fig. 22, suitably moved apart as the tube passes therethrough. The tube then passes between upper and lower driven rollers.
