Title: Improvements in a localising control device in machines for continuously feeding sheet material
IPC: B26D5/34
Filed: 1934-06-08
Abstract: 439,510. Feeding and registering webs. WEBER, H. G., 434, Bell Avenue, Sheboygan, Wisconsin, U.S.A. June 8, 1934, No. 17087. [Class 100 (i)] In a machine for continuously feeding sheet material, such as a paper bag machine, printed matter or designs on a travelling web of paper are localized with respect to rotary cutting means by a device which includes a variable speed mechanism in which the main drive is applied through a gear 41, spider 42 and pinion 43 to drive the draw roll shaft 45 through a gear 44 thereon. A worm wheel 47 capable of being driven in opposite directions at adjustable speeds is selectively operated to accelerate or retard the draw roll shaft in accordance with the sense of the deviation of the printed matter from the desired location in reference to the cutting means. The cutting-cylinder shaft 71 carries cams 68, 69 arranged to close switches 72, 76 once each revolution. These switches are mounted on an arm 85 which may be angularly adjusted by a shaft 87 and worm 88. The switches co-operate with means to be described in energizing alternatively relays 91, 101 controlling contactors 96, 106 which effect the drive of the worm-wheel 47 in a direction appropriate to maintain correct localization of the printed matter. The worm-wheel is driven by a worm 48 driven by one or other of two electric motors 59, 61 which operate jointly in a flexible band 56 operating through gearing 53 the worm shaft 49. These motors are arranged when energized to drive in opposite directions, their speeds being jointly adjustable by means indicated at 64. The contactors 96, 106 respectively energize the motors 59, 61. The web is provided, according to one arrangement, with characteristics which pass below a photo-electric cell 33 illuminated by light from a lamp 25, reflected from the web. The resulting changes in the resistance of the cell effect the energization of motor 59 or 61 according as the cam actuated switch 72 or 76 is closed when they occur, i.e. according to whether the web is advanced or retarded in regard to the cutting mechanism. In a modification, perforations in the web cooperate with contact arms adapted to contact with the roll to cause selective energization of the motors.

Abstract: 1,010,663. Heating air by exhaust gases. J. PRAT. May 4, 1962 [May 5, 1961], No. 17187/62. Headings F4K and F4S. The exhaust gases emerging intermittently from a converter or arc furnace are cooled to a temperature suitable for removing the dust therefrom in filters, e.g. cloth filters by connecting the outlet from the furnace to a heat exchanger 1 comprising vertical, straight fireresistant tubes 6 through which the exhaust gases are passed downwardly during a blowing period at a speed of more than 14 metres per sec., the heat exchanger being maintained in a condition to cool the exhaust gases to the required temperature by passing cooling air in the opposite direction to the exhaust gases. In Fig. 1, cooling air supplied by a blower 11 passes through a connecting pipe 13 into an annular chamber 13 whence slots 14 lead to a conduit of grate-like cross-section surrounding the tubes 6. The outlet from the latter conduit is through slots 17 into a further annular chamber 18 whence a connecting pipe 20 leads the heated air to a point of use. The heat exchanger is maintained at a uniform temperature by a thermostatically controlled valve 21. The exhaust gases are led off through a connecting pipe 9 to a cloth filter and dust collects in a bunker 7. In a modification valves are provided in the pipes leading the air and exhaust gases away from the heat exchanger and also in a further pipe connecting these pipes and the valves are controlled so that between blowing periods cooling air is passed upwardly through the tubes 6 by reversing a suction fan at the outlet of the connecting pipe 20. In Fig. 4 the dust bunker 7 has gates 28 and acts as a mixing chamber for exhaust gases which have passed down the tubes 6 and cooling air admitted at one side of the dust bunker. Between blowing periods valves 21, 27 at the bottom of the heat exchanger are controlled so that cooling air passes upwardly through the tubes 6 and out through a then open crest valve 30 to a point of use.
