Abstract: 551,560. Reciprocating pumps. SCINTILLA, Ltd. Aug. 27, 1941, No. 10943. Convention date, Aug. 27, 1940. [Class 102 (i)] [Also in Group XXIV] A driving shaft 2 has formed integrally therewith an eccentric 7 the centre of the eccentric surface being at 9. On this eccentric is rotatably mounted a second eccentric 10 the centre of which is at 12, the eccentricies e<SP>1</SP>, e<SP>2</SP> being equal to one another. The outer eccentric is held against axial movement by a collar 13 fast on eccentric 7 and a sleeve 14 between said eccentric and the bearing 4, the sleeve having a flange 15 with its centre at 9 and secured to the shaft 2 by a pin 16 and slot 17. The outer eccentric has a strap 18 connected to a pump plunger 21, and a pin 19 engaging a straight guide slot 20 in the casing 6. On the shaft 2 are respectively keyed and rotatably mounted identical bevel gears 25, 27 which mesh with a gear 29 keyed on a shaft 30 which may drive auxiliary apparatus, e.g. a feeding pump for forcing liquid into the suction chamber of the main pump. The bevel gear 27 is coupled to the outer eccentric 10 by a disc 33, projections 34, slot 36 on opposite sides of which and at right-angles to one another engage a groove 35, and projection 37 respectively on the gear 27 and eccentric 10. The eccentrics are thus rotated at equal angular speeds in opposite directions with the result that the centres 1, 9, 12 of the shaft, the eccentric 7 and the eccentric 10 are maintained always in the same vertical line, the stroke of the plunger 21 being equal to four times the eccentricity of one of the eccentrics. On a modification, the outer eccentric 10 carries two pins 42, Figs. 10, 15 upon each of which is rotatably mounted a lever 43, Fig. 11, the levers having toothed sector portions 44 which inter-engage. The other arms of the levers are of equal length and are pinned at 45 to links 46 also of equal length and pivoted at 47 to the gear wheel 27 described above. The pivots 47 are diametrically opposite one another, their distance apart is approximately equal to the mean distance between the pins 45.

Title: Improvements in or relating to register control systems for moving webs
IPC: B65H23/188
Filed: 1965-03-17
Abstract: 1,034,994. Automatic registration control. BOBST-CHAMPLAIN S.A. March 17, 1965 [March 31,1964], No. 11247/65. Heading G3R. In a control system for a moving web, errors in registration are automatically corrected through a silicon-controlled rectifier between an A.C. supply and a register correcting motor operating intermittently. In Fig 1 (not shown), a web 32, preprinted with a repeating pattern, Is drawn from a reel 34 by rolls 36, 38 and over-printed, cut or otherwise operated on by a rotary member 42 the drive to which is derived from the drive to rolls 36,38 through a variable speed gear 44 and a differential gear 50. To ensure correct registration between rotary member 42 and the pattern on the web a generator 58 driven with rotary member 42 is arranged to produce a pair of adjacent pulses at each revolution and the timing of these is compared with a narrow pulse produced at each repetition of the web pattern by a photo-electric transistorized scanner 56 of adjustable sensitivity and suitable for light or dark background materials. The pulses are produced through Schmitt-trigger circuits and, if registration is correct, the scanner pulse occurs in the interval between the two other pulses. Coincidence of the scanner pulse with one or other of the other pulses is however detected by coincidence circuits and indicates deviation from correct registration in one sense or the other to operate a corresponding one-shot multivibrator and apply a voltage at double mains frequency for a predetermined period to render a corresponding pair of reversely connected silicon-controlled rectifiers conductive to energize a reversible twophase motor 52 so that it runs in the appropriate direction to correct the register by driving the other input to differential gear 50 for the period. A digital counter associated with generator 58 may be preset so that the registration test is made once every one, two, four, eight or sixteen revolutions to allow sufficient time for any correction to be effective and avoid hunting. One further digital counter is preset to select groups of four, five, six or seven consecutive registration tests and others add up the numbers of errors in each sense. If there are four or more consecutive errors in the same sense in any group, indicating an error trend, a motor 90 is operated by a silicon-controlled rectifier arrangement similar to that for motor 52 so that an incremental adjustment of variable speed gear 50 is made to eliminate the trend. In a modification motor 52 adjusts the length of a loop in the web instead of a differential gear to provide the register correction. Application to intermittently fed webs is referred to.

Title: Electric welding apparatus
IPC: B23K11/24
Filed: 1920-04-26
Abstract: 142,804. Murray, T. E. May 2, 1919, [Convention date]. Heating by electricity.-In an electric welding apparatus having two co-operating electrodes, the current traversing the joint is controlled so as to heat one or more predetermined localized fractional areas of the joint. The current distribution at the joint, which tends to become irregular consequent on increase of area or change of shape of the welded surfaces, or changes in the physical characters of the metal, or non-uniformity of thickness or diameter of or deformation of the objects, is thus controlled to obtain either a uniform distribution of the heating effect throughout the joint, or to enable sections of the joint to be heated more than other sections or to be heated in succession. In the form shown for welding the longitudinal half sections C, C' of a tube of uniform diameter and thickness and of homogeneous metal, the lower electrode B is placed across the centre portions L of the secondaries E, F, G, H, I, J, K of a series of transformers, the primaries of which are connected in parallel by switches T with the welding current leads R, S. Each secondary consists of a pillar L and two arms M which are connected by wires U, V to the movable electrode A and contains a pair of primaries 0 carried by cores P, Q, which may be turned towards one another at the ends, and preferably meet. Any transformer or group thereof may be cut out by its switch or a number of the turns of a given primary may be cut out according to the effect desired. To prevent cooling by the air of the ends of elongated objects, the two end transformers are energized even if a sufficient distribution of heating effect is obtainable with a number of the intermediate transformers. Reference has been directed by the Comptroller to Specifications 12747/87 and 18625/90.
