Making rolls.-In manufacturing a roll, such as described in Specification 591,541, the roll is first turned to the shape shown in Fig. 7. The shape of the grooves is then modified by a further turning or grinding operation to the shape shown in Fig. 10. The cutter is then fed to cut a groove, is withdrawn, the roll is indexed, and so on until all the transverse grooves have been cut in one circumferential groove. The roll is then traversed to bring the next groove into position. Two cutters may be mounted to out adjacent'grooves simultaneously. If the-grooves are staggered in adjacent pairs, two cutters may be spaced apart to cut alternate grooves simultaneously. The procedure may be modified by cutting the grooves before superimposing the outline of Fig. 10, to produce the finished form, Fig. 11. Milling-cutters.-The cutter has carbide teeth which may be integral with the hub and is joined to the shaft 18 by silver solder or by a tongue-and-groove connection. The teeth are backed-off radially 5 degrees and also axially of the shaft 18.

Abstract: 451,207. Valve amplifying circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Feb. 13, 1936, No. 4434. Convention date, April 15, 1935. [Class 40 (v)] Volume expansion is effected in a low frequency amplifier 1, 3 by rectifying a portion of the output, derived from a potential divider 11, by a diode 8 and using the rectified voltage produced in resistance 9 to control the anode current of an auxiliary valve 2. This variable anode current passes through the anode resistance 4 of the amplifier 1 and operates to increase the anode voltage thereof when the signal amplitude increases. The anode current of valve 2 also passes through a pre-set portion of the cathode resistance 5 of valve 1 so that when the anode voltage of the latter rises its grid bias also becomes less negative. The cathode of valve 1 is connected to a tapping 18 on the resistance 5 so that the intensity of the contrast may be adjusted. A filter 17 may be provided to remove from the control energy high frequencies and in some cases high and low frequencies. In amplifiers having separate channels for different frequency bands, the control energy may be derived from one or more of said channels and applied to a plurality of rectifiers whose outputs are combined.

Title: Improvements in and relating to resistance regulators
IPC: H02P9/22
Filed: 1945-02-23
Abstract: 630,366. Automatic regulators. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Feb. 23, 1945, No. 4565. [Class 38 (iv)] [Also in Group XXXVI] A carbon pile type regulator in which movement of an armature towards or away from the poles of an electromagnet varies the pressure on the pile, and thus its resistance, is characterized in that the co-operating faces of the armature and poles are of stepped formation. In the carbon pile shown, Fig. 7, the adjacent faces of the armature 36 and the pole-pieces 7 of the U-shaped electromagnet 4 are notched or stepped in such manner that as the vertical air-gap decreases to a minimum with horizontal air-gaps present between the vertical surfaces of 7 and 36 the pull of the magnet is diminished since greater flux is present in the narrow horizontal air-gaps than in the wider vertical air-gaps. In Fig. 7, two ribbed cylinders 3 are shown and each of these encloses a rheostat pile made up of a stack of carbon discs 16 interleaved with metal springs 17, Fig. 5, which latter act as cooling fins and permit metal inserts 22, Fig. 6, to make contact and thus short-circuit the pile when full pressure is applied. The frame 32, Fig. 7, carrying the armature 7, is pivoted at 33, 34 so that movement of the armature 7 one way or the other results in opposite movement of a spring 37 and cross-piece 28 to increase or relieve the pressure on each pile; the cross-piece 28 connects the two rheostats in series. The lever 38, Fig. 4, which may be moved to effect adjustment of the spring tension and thus the setting of the regulator is a bimetallic strip designed to provide automatic adjustment of the spring tension to compensate for change in resistance of the electromagnet windings and alteration in dimensions of the various parts with variation in temperature. The former effect is additionally compensated by a temperature-variable resistor mounted within the regulator, Fig. 2 (not shown) and in series with the parallel connected electromagnet windings, Fig. 9 (not shown). Copper rings 45 encircling each limb of the electromagnet 4, Fig. 7, provide inherent opposition to change of flux. The regulator includes as components a pair of capacitors, Fig. 1 (not shown), stated to form part of an anti-hunting circuit not described. A plug-in arrangement, Fig. 2 (not shown), connects the regulator, for example, to maintain constant the terminal voltage of a D.C. generator (Fig. 9, not shown).

Title: Improvements in or relating to the method of and mechanism for opening sheets in sheet-handling machines
IPC: B42B2/02
Filed: 1931-02-14
Abstract: 372,427. Opening out folded sheets. POLLAK, J. E., 20, Holborn, London.- (Brehmer Geb. ; Plagwitz, Leipsic, Germany.) Feb. 14, 1931, No. 4778. [Classes 89 (iii) and 112.] In a mechanism for opening out folded sheets or sections and feeding them to the swinging sheet carrier of a sheet-handling machine, the sheet-opening device is caused, during each of its operative periods, to move with the sheet carrier throughout some part of the travel of the latter. By this arrangement, the opening device is allowed a longer period for placing the sheet on the carrier. As shown, folded sheets S supplied by tapes 19, 19a are opened out by inversely-rotating suction rolls 24, 25, and deposited upon the swinging sheet carrier 17 which carries them to the stitcher head 13. The roll 25 is journalled in brackets carried by a bar 26 slidable in oblique guides 27. The roll 24 is journalled in members 29 slidable in guides 28 carried by the bar 26. The bar 26 is operated by linkage 42, 41 and a cam 43 to move the rolls 24, 25 towards and away from the stitcher head in timed relation with the movements of the sheet carrier 17. The conveyer belts are mounted to move with the rolls 24, 25. The latter are oscillated, to perform their opening out functions, by gearing 30.. 33 and a toothed segment 34 adjustably driven from a cam 39 through a link 37 and slotted arm 36. The rolls 24, 25 are arranged to move apart, at the moment a folded sheet is fed to them, to allow the sheet to be lined up by registering stops 14. To this end, the members 29 are moved, at the appropriate times, by cams 51 operated from a cam 57 through linkage 54, 55. The stops 44 are controlled from the same linkage through links 46, 48, 58, 59, so that the stops move to inoperative position as the roll 24 returns to grip and feed the sheet. In operation, the suction rolls begin to open out a sheet while the sheet carrier is making its idle return movement. The rolls follow the carrier in its movements, and complete the delivery of an opened-out sheet upon the carrier in the course of the operative movement of the latter ,o stitching position. In a modification, Fig. 8, the suction roll 24 is given an arcuate motion about the axis of the roll 25, in addition to its operative rotational motion. The rolls are positioned midway above the path of movement of the carrier 17, and receive a sheet while the carrier is at stitching position. While the carrier is making its idle return stroke, the roll 24 is given its arcuate movement, so that it follows the carrier. The latter, in its next operative stroke, moves into the partly opened sheet, which is then released by the return movement of the roll 24 along its arcuate path.
