Delivery, stopping; roller heads. - T h e thread passes through the guide o between gripping-jaws d<2>, d<3>, between the rollers A A', B, B', over the detector k<2> to the flyer C. The gripping-jaw d<3> is fixed and the jaw d<2> is carried by a rod d' controlled by a spring d<4>. The detector k<2> is pivoted in a bracket h carried by the roller brackets f. The end k<1> of the lever k is connected to a rod w having at its upper end transverse pins m<1>. The presser roller A<1> is mounted in weighted brackets b pivoted on knife edges c, and normally an extension b<3> on the bracket b engages a catch d' on the movable gripping-jaw d<2> and holds the jaws apart, When a thread breaks, the detector k<2> rises, the rod m falls carrying the pins m<1> between the rollers A, A<1>. The rotation of the rollers carries the pins further between them and they are thereby forced apart and the projection b<3> removed from the catch d<7>. The gripping-jaw d<2> is released and the thread held between the grooved and ridged jaws d<2>, d<3>. The lever k carrying the detector k<2> is controlled by a spring n so that the detector may spring forward into the full-line position on breakage of the thread or be forced back into the dottedline position to facilitate the repairing of the broken thread. To allow the gripping-jaws to be operated irrespective of the breaking of the thread, a handle b<6> is provided on the bracket b. A finger-piece s is provided on the movable jaw d<2> The catch b<3> may be on a pivoted part not integral with the bracket b, but controlled by the movement of the bracket.

Abstract: 925,230. Duplicating-machines; damping and inking apparatus. ROTAPRINT Ltd., and C. G. KING. Feb. 2, 1961 [Feb. 4, 1960], No. 4059/60. Class 100 (2). A duplicating machine having means for applying ink repellant to a master sheet mounted on the plate cylinder 1 comprises a pivotally mounted reservoir 10 for ink repellant, an absorbent pad 12 adapted to absorb ink repellant from the reservoir, means for pivoting the reservoir between an inoperative position wherein the pad is spaced from the master sheet and an operative position wherein the pad is in contact with the master sheet to apply ink repellant thereto, an inking roller carried in a swingable frame 3 between an inking position for inking the master sheet and an inoperative position spaced therefrom and means connected with said inking roller operates to move the pad into inoperative position as the roller is moved into inking position and prevent the movement of the pad into operative position until the inking roller is withdrawn from inking position. The reservoir 10 and pad 12 are mounted in a frame 9 supported on a rotatable rod 6 which is biased by a spring 6a to the operative position of the pad. Rotation of the rod is effected by a slide member 13 pivotally connected at its lower end by a link 21 to an arm 7 forming part of the frame 9. This slide member, which is guided through the interengagement of a pin 15 fixed to the machine frame with a slot 14 in the member, carries a pivoted actuating lever 16 and a flanged upper end for engagement with a stop member 3a depending from the inking roller frame 3. The lever 16 is spring-loaded upwardly such that a pin 17 thereon abuts an edge of the member 13 and the inner end of the lever is formed with a nose which catches beneath a stop member 20 secured to the machine frame when the lever 16 is depressed such that the slide member 13 moves downwardly allowing the inking roller frame to drop and thus bring the roller into contact with a master sheet on the plate cylinder.' This downward movement of the member 13 swings the pad and reservoir away from the cylinder against the action of the spring 6a, the pad &c. being held in this position by the engaged lever nose and stop 20. Further depression of the lever such that it pivots on the member 13 disengages the nose and stop such that the spring 6a causes the member 13 to move upwardly thereby simultaneously pushing the inking roller away from, and applying the pad &c. to the cylinder 1. During a printing run moistening liquid will be supplied to the master sheet by one of the inking rollers as is well known.

Title: Improvements in or relating to a method of treating products with electro-magnetic energy
IPC: A23L3/28
Filed: 1948-02-18
Abstract: In the irradiation of products such as foods and therapeutic substances to destroy bacteria or virus therein, radiation of a frequency exceeding 107 cycles per second is applied with an intensity which if continued would produce detrimental heat effects, the radiation being however applied in pulses so short that detrimental heating does not occur.  The pulses are preferably flat-topped; in the case of infrared and ultra-violet rays they may be produced by a revolving shutter and in the case of radio waves and X-rays by known modulating devices.  Preferably the period of treatment exceeds the duration of the life-cycle of the organisms to be killed and the interval between pulses is shorter than that part of the cycle in which the organism is most sensitive.  In an example blood serum is irradiated by a mercury vapour lamp fed with a current having a pulse length of 200 microseconds and a pulse recurrence frequency of 1,000 per second, whereby the temperature of the serum does not rise above 30 DEG C. Specification 538,361 is referred to.
