Filed: 1934-12-12
Abstract: 451,931. Cutting webs of paper. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (International Cellucotton Products Co. ; 180, North Michigan Avenue, Chicago, U.S.A.) Dec. 12, 1934, No. 35690. [Class 31 (i)] [See also Group XVI] In a paper-folding machine a web of paper is severed transversely at longitudinally spaced intervals by severing means which includes a roll having a longitudinally unbroken smooth surface from which the severed sheets are delivered to folding means, the removal of the sheets from the roll being effected by a stripping means which is mounted so as to permit a bevelled edge thereof to follow the surface of the roll under the action of means which yieldingly urge the bevelled edge into engagement with the roll surface. As shown, there are two webs A, B of paper, for example soft flimsy tissue paper such as cleansing tissue, the web A passing through feed-rollers 1, 2, and around a gutter roller 5, and the web B passing between feed-rollers 3, 4 and around a gutter roller 6, the two webs being brought together and caused to pass downwardly between guides 7, 8 to a pair of feed-rollers 9, 10 which feed the sheets cut from the webs to folding means. Cutting-rollers 18, 19 cooperating respectively with the rollers 5, 6 each carry a pair of diametrically oppositely disposed knives 20, the diameter on which the knives are located in one roller being 90‹ out of phase with the diameter on which the knives are located in the other roller. The gutter rollers 5, 6 each have a longitudinally unbroken smooth surface, and are each provided with a pair of grooves 21 to cooperate with the knives 20 on the corresponding cutting-roller. The webs A, B are thus alternately severed so that each of the cuts in the web A will be disposed substantially mid-way between a pair of cuts in the web B. The guides 7, 8 are mounted on shafts 22 and consist of a series of stripping elements 23 and guiding elements 24. Each guiding element 24 is an elongated finger-like member having a head portion bored out to fit the shaft 22 and provided with clamping means, and each stripping element 23 includes a finger-like member 28 arcuately bevelled at 29 to fit the surface of the roller 5 or 6 to strip the sheets therefrom.

Abstract: 411,911. High vacuum apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GALLIZIA, E., c/o General Electric Co., Witton, Birming- ham. Dec. 16, 1932, No. 35696. [Classes 8 (i) and 71.] Apparatus for evacuating a mercury-arc rectifier &c. comprises a high vacuum pump and a backing pump, and a mercury &c. liquid seal which, in the event of failure of the high vacuum pump, separates the backing pump from the evacuated apparatus. Fig. 1 shows a diffusion pump 1 which evacuates a rectifier through a pipe 2 and a main valve ; the outlet of the pump 1 is connected to a rotary backing pump by pipes 6, 7 and a barometric valve 5. A seal in the pipe 2 is provided by mercury in a gutter formed in an enlargement 18, and a cap 20. The mercury reservoir 23 connected with the gutter is subject through the pipe 24 to the pressure in the pipe 7 in which is a leak valve 8. Opening of this valve gives atmospheric pressure in the reservoir 23 and causes the mercury to rise and close the seal. Closure of the main switch 11 starts the pump 4 and the heater of the diffusion pump, and the valve 8 is closed after a time by a time delay mechanism 13 operated by the heater winding 3. If the heater current fails the leak valve is opened and the seal closed. In a modification, closure of the main switch first starts the heater only, the current supply to operate the pump motor and that to close the leak valve being started simultaneously by the time delay means. Fig. 4 shows apparatus in which a reservoir 28 between the diffusion pump 1 and backing pump 4 carries a pressure-actuated contact 29 to close the circuit of the pump motor and leak valve 32 ; a barometric valve 30 is provided between the reservoir and the backing pump, and a like valve 35 is provided in the pipe leading to the mercury reservoir ; a leak valve 37 in this pipe is controlled by a pressureresponse contact 39 in the return pipe of the pump 1. Surplus mercury condensing in the seal or the pipe 2 is caused to return to the diffusion pump by overflow &c. The mercury reservoir 23 and barometric tube 22 may be replaced by a plunger in a reservoir or by a movable reservoir or one having flexible sides to vary the level in the seal, or the cap 20 may be movable by a solenoid. The seal may be controlled by a Pirani gauge or gauges actuated by the high vacuum and the pressure, e.g. in the mercury boiler.
