Abstract: 1,272,087. Handling sheets. ADDRESSOGRAPH - MULTIGRAPH CORP. 13 May, 1969 [7 June, 1968], No. 24372/69. Heading B8R. [Also in Divisions B6 and G2] A photoconductive sheet 28 is charged at 81, imagewise exposed at 50, has surplus charge removed by lamps 150, and is clamped to a drum 52 which repeatedly rotates past a developing station 56 and a transfer station 58 to produce copies on sheets 34; sheet 28 being ejected when a preselected number of copies has been made, or at the discretion of the operator. Before use, the operator adjusts a mirror 96 and lens 98 according to whether a reduced or same-size copy is required. This adjustment makes one of switches 90 and 92 operable. In use, a sheet 28 is fed by a roll 76, trips a switch 80 to disable roll 76, is fed past charger 81 and trips switches 90 and 92. Switch 90 or 92 energizes xenon lamps 94 for imagewise exposure and also energizes a time delay (321 or 324, Fig. 12, not shown) which operates surplus charge clearing lamps 150 as the trailing edge of the sheet passes the delay being determined by which of switches 90, 92 has been made operable by the adjustment of the optical system. Switch 90 or 92 also energizes a time delay (326) which on timing out de-energizes the charger 81 and sheet feed rolls 72 to 75 and energizes a motor 154. Motor 154 rotates drum 52 so that a follower 198 (Fig. 5) moves away from a cam 202 allowing springs 182 to close a clamp 176 on the edge of the sheet. Motor 154 also starts feeding copy sheets 34. The drum rotates past an electrically biased magnetic brush 56 and a transfer roll 58 comprising a metal shaft having a semi-conduction shell and the developed images are fixed by rolls 268, 270. When a copy counter (44) or manual switch (329) are operated, a cam 206 engages follower 198 to release the sheet 28 which is fed out with a copy sheet to prevent developer offset on to transfer roll 58. A solenoid (258, Figs. 11, 12, not shown) then disables the copy sheet feed and finally motor 154 is deenergized.

Abstract: 1387045 Preventing vibration of centrifuge rotor IVAN SORVALL INC 25 May 1972 [28 June 1971] 24793/72 Heading B2P [Also in Divisions E2 and F2] A centrifuge comprises a frame (12), Fig. 1 (not shown), a vertical rotatable drive shaft 32 supported on the frame, a rotor (71), 73, a rotor shaft 52 having one end portion 51 pivotally connected to the drive shaft and rotated thereby and the other end portion 53 operably pivotally connected to the rotor, and an articulating connection 57, 89 provided between the rotor and the drive shaft and movable in a horizontal plane relative to the vertical axis of the drive shaft when the rotor shaft 52 moves pivotally and the centre of gravity of the spinning rotor moves to become aligned with the axis of rotation of the drive shaft. The drive shaft 32 is mounted in bearings 34 in a housing 16 which is supported by a resilient rubber cushion 21 on a mounting ring 13 bolted to the frame. A power shaft 11 is driven by an electric motor, a turbine, a belt and pulley combination, or gearing, and is connected to the shaft 32 by a resilient coupling 24-28. The upper end of shaft 32 terminates in an enlarged crown 41 having a skirt 42 defining a chamber 43 in which a slide block 57 is horizontally movably mounted on a ball thrust bearing 56 and is retained against undue free movement between the latter and a friction ring 58 by a spring washer 59 engaged below a flange 45 formed on a clamp ring 44 threadably connected to crown 41. Clamp ring 44 may be provided with radially and vertically extending slots (61), Fig. 4 (not shown), within which centrifugal locking levers 62 are pivotally mounted on pins 63 and above a predetermined speed bear upon friction ring 58 to cause the latter to lock sliding-block 57 in an immovable position. The hub 73 of the rotor (71) has a recess 77 which accommodates a bearing block 78 retained by a clamp ring 82 having a flange 84 upon which rests a spring washer 86 which supports a friction ring 87. A universal hollow ball joint 89 slidably engages bearing surfaces 79, 81 on the bearing block and a seat 88 on the ring 87. The ball joint is integrally formed with a tapered sleeve 91 which is secured within a collar 92 on the sliding block 57 by a nut 93. The rotor shaft 52 has square ball ends 51, 53 which are pivotally accommodated in square-shaped apertures in inserts 47, 76 secured in annular recesses 46, 74 in crown 41 and hub 73 respectively. In operation, during the start-up or slowing down period, any imbalance of the rotor causes the geometric centre of the rotor and of the hub 73 to depart from the axis of rotation of the drive shaft 32, this being permitted by the sliding action of the block 57 and the pivoting action of the shaft 52. Consequently, the combined centre of gravity of the rotor and hub is brought into alignment with the axis of rotation of the shaft 32 thereby preventing vibration of the rotor, when the rotor attains a predetermined speed the levers 62 lock the sliding block 57 securely between the friction ring 58 and the bearing 56.
