Title: Electrical data-indicating apparatus
IPC: H03K21/08
Filed: 1950-12-11
Abstract: 682,229. Electric selective signalling systems. NATIONAL CASH REGISTER CO. Dec. 11, 1950 [Dec. 17, 1949], No. 30201/50. Class 40 (i) [Also in Group XIX] Apparatus for indicating an item of data registered in a circuit network by the application of a distinctive potential to a corresponding one of a plurality of data representing points in the circuit comprises a device responsive to the distinctive potential to operate an indicator to show the corresponding item of data, and compensating means controlled by the supply potential to regulate the indicator-operating device in accordance with the supply potential to prevent faulty operation due to variations in the supply potential. The anodes of the four double-triode trigger pairs A, B, C, and D of a coded-decimal accumulator, such as that described in Specification 682,221, [Group XIX], are resistance-coupled to ten leads 435 in various combinations so that the lead 435 corresponding with the digit registered is at a predetermined potential lower than that of any of the other leads. The leads 435 are connected to the contacts of a rotary switch, the arm of which is connected to the grid of a triode 421 and is rotated by a friction drive. When the arm contacts the line having the lowest potential, the triode 421 is rendered non-conducting and an electro-magnet 420 in its anode circuit is de-energized. A pawl 415 is thus released into engagement with a notched wheel 413 on the shaft of the arm, which is thus held against further rotation. A drum 411 on this shaft indicates the corresponding digit. In order to compensate for supply-voltage fluctuations, a second triode 430 has its cathode connected to the cathode of the triode 421 and its grid connected to a potentiometer 433 across which the main voltage supply is connected. If the supply voltage decreases, the potential of the two cathodes decreases, due to the decrease in current flow in the triode 430, and the potential difference between the grid and cathode of the triode 421 is maintained substantially constant.

The salts are useful as rubber tackifiers and for rubber-base adhesives.
Patent GB-956145-A (GB)
Title: Improvements relating to the stacking of sheets
IPC: B65H43/04
Filed: 1959-09-08
Abstract: 956,145. Cutting apparatus. PORTALS Ltd., A. J. TOOTH, and D. WALMSLEY. Aug. 17, 1960 [Sept. 8, 1959], No. 30669/59. Heading B4B. [Also in Division B6] Stacked sheets, which may have been cut from a web, are each formed in one edge with a notch. If one sheet, e.g. sheet 11, be wrongly orientated in the stack, it will interrupt a photo-electric beam to operate a warning device 14 or prevent operation of a guillotine for subdividing the sheets. A water-marked web is notched, cut into sheets and these, after various operations involving stacking and unstacking, are printed in register with the watermarks. Alternatively a web may be printed and cut transversely into sheets each of which is also notched at the same time and then the sheets are subjected to stacking and unstacking operations prior to guillotining in register with the printing. Cutting webs transversely (Fig. 3).-The web 23 is forwarded from a supply roll over guide rolls 21, 22 to a cutter by driven rolls 24, 25, the nip pressure of which is adjustable. The cutter comprises a fixed knife 33 and a revolving knife 32 carried on a driven drum 36. To vary the length of sheet drum 36 is driven through a variable-speed drive. Notching the edge of sheets or webs (Fig. 4).-In the case of sheets, the notching device is synchronized with the sheet feed. In the case of webs, the notching device is located between the guide rolls 21, 22 (Fig. 3), and is driven in synchronism with the transverse cutting knife 32. The web passes between discs 41, 56 rotating with shaft 42 in synchronism with cutter 32. The edge of web 59 overlies a U-shaped radiallyadjustable cutter 43 on disc 41, with which cooperates a cutter 45 pivoted about an axis 47 and normally held in raised inoperative position by a stationary cam 51. When the discs have rotated to bring the knives to the correct position, the cam 51 allows knife 45 to drop through an aperture in disc 56 under the influence of springs 50 to cut a notch, the waste falling into collector tube 55. The effective circular path of the knives equals the sheet length so that the speeds of the knives and paper during cutting are equal. To vary the position of the notch along the sheet edge, the shaft 42 and the shaft of knife drum 36 are in axial alignment and terminate in flanges which are bolted together; the flanges can be unbolted and bolted up again in a different relative position thus changing the position of the notch relative to the transverse cut.
