Title: Apparatus for and method of treating plastic film
IPC: B41M1/30
Filed: 1953-01-27
Abstract: 722,875. Printing processes. VISKING CORPORATION. Jan. 27, 1953 [Feb. 9, 1952], No. 2305/53. Class 100 (2). A method of treating plastic film to improve the adhesion of ink impressions imprinted thereon comprises subjecting the opposite surfaces of the plastic film simultaneously to the action of high voltage stress accompanied by corona discharge. As shown, a web 10 is unwound from a supply reel 12 and after passing over rollers 16, 18 passes between electrodes 24, 26 one of which is earthed and the other of which has a high voltage applied thereto by means of a high-voltage transformer 60. The web then passes over rollers 20, 22 on to a take-up roll 14. Alternatively the web may be fed directly to a printing machine. The ground electrode 24 is carried on posts 30 and is provided with notches, Fig. 3 (not shown), on each longitudinal edge so that a glass cord may be threaded therethrough and held in position, thus acting as a spacing member for the web. The high voltage electrode 26 is secured in a recess formed in the inner periphery of a frame 40 formed of insulating material and a solid dielectric 42 is disposed on the upper surface of the electrode. The electrode 26 is supported on posts 50, and a glass cord 46, for spacing purposes, is wound on pins .44 extending from the frame 40. In alternative arrangements the glass cords may be wound spirally around the electrodes, Fig. 4 (not shown), or a fabric may be disposed over each electrode, Fig. 5 (not shown), or both methods employed. The voltage on the high voltage electrode 26 is preferably between 10,000 and 20,000 v., and the electrode may be made of stainless steel.

Patent GB-413740-A (GB)
Title: Improvements in or relating to paper-perforating and fastening devices
IPC: B26F1/36
Filed: 1934-01-23
Abstract: 413,740. Paper perforating and fastening devices. ROEDER, F., and ROEDER, C., (trading as ROEDER, S.), 123, Ritterstrasse, Berlin. Jan. 23, 1934, No. 2333. Convention date, Jan. 23, 1933. [Class 31 (ii).] A device for connecting sheets of paper by means of punched-out paper tongues is convertible from a connecting device into a per. forating device and vice-versa by means of a slide 35, mounted in a hollow base 1 and having two sets of holes, one set 39 being large enough to allow U-shaped punches 20 and means for connecting the sheets to pass, and the other set 40 allowing only the closed end portion 21 of the punches to pass for perforating, and retaining the connecting means. The punches 20 are guided in lugs 16, 19 of brackets 5 and are joined by a stay 10 which engages a handle 7 provided with return springs 9. A bar 13, whose ends 15 engage under lugs 16, carries slotted members 14 which limit the upward movement of bar 10 and handle 7, and the ends 15 are pressed onto the paper by a bow spring 12 when the device is operated. When fastening sheets together, the member 24 is diverted by the engagement of a finger 25 with a lug 48 on the bar 31 so that a second finger 26 pushes the tongue cut by punch 20 through an opening in a knife 28 and through a slit in the paper cut by the same. Each knife 28, guided by an extension 19<1> of lug 19, is pressed down by a spring 32 attached to the punch 20, and is limited in movement by a slot 31 and projection 30 in the punches. The slide 35 is locked in either position by the interaction of a cam 41<1> and spring 42.
Patent GB-575862-A (GB)
Title: Improvement in fuel injection apparatus
IPC: F02M57/02
Filed: 1944-02-08
Abstract: 575,862. Fuel injectors. BENDIX AVIATION CORPORATION. Feb. 8, 1944, No. 2349. Convention date, Nov. 13, 1942. [Class 7 (iii)] In fuel injection apparatus in which the flow of fuel from a pump into the engine cylinder is controlled by a valve responsive to fuel pressure and a second valve responsive to higher pressure only provides a byepass from the pump to the supply line, the two valves and the pump are arranged in axial alignment with one another. The second valve presents a smaller area to the fuel pressure than the first valve and is responsive to a predetermined maximum pressure only. Fuel, circulating continuously between passages 38 and through an annular chamber 37 surrounding a pump cylinder 18 to serve as a coolant, enters the cylinder through ports 36 and is forced downwards until it can escape through axial and radial passages 41, 42 in the plunger 35 when a helical groove 40 therein uncovers a spill port 39 in the cylinder, manual rotation of the plunger in known manner determining when this occurs. The pump forces fuel through passages 17b in a disc 17, 33 in the body 13 of a nozzle holder and 28 in a valve guide 24 to a chamber 27 where its pressure operating against a shoulder 29 on a delivery valve 25 lifts the valve to permit discharge of the fuel through a passage 21b and orifices 21c. The valve 25 is normally held seated by a spindle 30 engaged by a spring 62 on a support 58 into which the spindle is screwed to a depth determined by a number of shims disposed between the end of the spindle and the screwed socket in the support to adjust the pressure of the spring. The spring 62 also seats a valve 60 closing an escape passage 61 from the pump cylinder, the effective area of the passage being less than that of the shoulder 29 on the delivery valve 25 to ensure that the escape passage will not be opened unless pressure builds up due to failure of the delivery valve 25 to open. The escaping fuel returns to the chamber 37 through passages 63-66. To adapt the pump to deliver only a limited quantity of fuel should the delivery valve 25 fail to close, the cam 57 actuating the pump, is formed with a long circular portion a-b which holds the plunger 35 with its end just closing the inlet ports 36. Near the time for injection, the cam follower 56 rides down a slope b-c on the cam permitting the pump spring 50 to complete the suction stroke of the plunger 35 whereupon the crest d-e of the cam effects the delivery stroke. A simple cam may replace the cam 57 if an outwardly opening spring pressed valve is disposed between the pump chamber and the relief valve 60 so that fuel is only delivered through the passages 17b, 33 and 28 to the delivery valve 25 when the fuel pressure is sufficient to open the valve.
Patent GB-1585892-A (GB)
Title: Tdm switching networks
IPC: H04Q11/04
Filed: 1977-01-21
Abstract: A switching matrix design is to be found which can be applied uniformly for all switching matrix sizes and allows a switching matrix to be expanded in small steps. Having regard to the fact that the switching matrix units effecting the switching-through should be integrable, in addition, only a small number of line connections should be required for these. This is achieved by the fact that the time-division multiplex lines (1Zan to nZab and 1San to nSab) are arranged in the manner of a matrix and can be connected at their points of intersection by switching matrix units (KE) which exhibit a smaller traffic handling capacity than can be fully achieved. The larger the switching matrix, the smaller the traffic handling capacity of these switching matrix units. The switching matrix units (KE) are suitably constructed in the form of shift register rings. <IMAGE>

Title: Improvements in or relating to clutches
IPC: F16D41/02
Filed: 1958-01-24
Abstract: 833,941. Friction clutches; gearing for stopping and starting machinery. TELEPRINTER CORPORATION. Jan. 24, 1958 [Jan. 30, 1957], No. 2522/58. Class 80 (2). A clutch for use in a teleprinter comprises a driving shaft 62 adapted to be engaged by rollers 30 in notches 28, Fig. 4, in a cage disc 26 having at least one housing disc 36 to one side formed with wedging slots 38 for the rollers 30, in the form shown two housing discs 36 on opposite sides of the cage disc being connected by rivets 58 passing through tangential slots 32, 34 in the cage disc and springs 64 biasing the cage disc 26 in such a direction as to wedge the rollers 30 against the driving shaft 62. The clutch is disengaged by introducing a brake finger into the path of teeth 110 on the cage disc, which is accordingly held stationary so that the rollers 30 become unwedged and the driving shaft rotates freely within them. A driven member 56, which may be a cam or gear, is secured to the housing disc 36 by the rivets 58. In one form, clutch disengagement is effected by a brake finger 116, Fig. 10, pivoting at 118 and movable into the path of teeth 114 on the cage disc. The brake finger is connected by a tension spring 122 to a pivoted rebound arm 166 which, when the brake finger is moved to disengage the clutch, is simultaneously moved into the path of teeth 164 on one of the housing discs. The arrangement is such that the cage disc and the housing disc are held so turned relatively to each other that the rollers 30 are completely free of the driving shaft 62. The brake finger 116 and the rebound arm 166 form part of a teleprinter and are controlled by energization of a solenoid 182 acting upon a flipper 180 in combination with a sequence control cam 186. In a modification, the brake member is shown as an arm having a hooked end engaging over teeth on the cage disc, so that it acts in tension rather than in compression. According to the number of teeth provided on the cage periphery, the clutch can be arranged to disengage after one, or a half, &c., revolutions. As another modification, the clutch driving member may be hollow. In Fig. 1 (not shown), a number of clutches according to the invention are arranged side-by-side on a common driving shaft for use in a teleprinter, one of the clutches carrying both a driven cam and a driven gear and the rest of the clutches carrying driven cams only. Two such shafts may be connected coaxially by a coupling (not further described). Specifications 799,956 and 833,942 are referred to.
