Abstract: 1468865 Controlling laminated paperboard manufacture HARRIS CORP 14 Aug 1974 [26 Dec 1973] 35856/74 Heading B5N [Also in Division G3] In the production of corrugated paperboard by feeding single-face board from a single-facer to a bridge and withdrawing board from the bridge to a double-facer, the speed of the singlefacer is controlled so that a unit length of board remains on the bridge for a predetermined time regardless of the speed of the double facer. This may be done by generating signals indicative of the amounts of board fed to and from the bridge, comparing them to yield a differential signal indicative of the amount of board on the bridge, comparing this differential signal with a control signal indicative of the desired residence time for a unit length of board, generating an output signal as a result of the comparison and using it to control the speed of the single facer. In the arrangement shown, sensors 64, 66 determine the amounts of board 36 fed to and removed from bridge 38, e.g. by counting flutes or spaced marks by means which generate pulses, and pass signals to an "up-and-down" counter 70. The control signal is given by an attenuator 74 which receives a signal from a tachometer connected to the double-facer. Counter 70 may be replaced by an analogue integrator, in which case converters 84, 86 are unnecessary.

Abstract: 897,460. Stuffing-box substitutes. MIXING EQUIPMENT CO. Inc. Oct. 25, 1960 [Oct. 27, 1959], No. 36557/60. Class 122 (5). The rotatable shaft 34 of a mixing or other machine is detachably connected to a driveshaft 32 and sealed where it passes through a closure member 38 for an opening in the machine casing 22 and means are provided to hold the shaft 34 against axial movement whilst the shafts 32 and 34 are disconnected from each other to permit removal and replacement of the sealing means 62. The drive shaft 32 is driven through gearing from a prime mover and is connected to the shaft 34 by a flanged coupling 88, the flange 90 on shaft 34 consisting of a body portion 100 and a sleeve portion 102. The closure member 38 is formed by an intermediate portion 50 welded to an outer portion 42 and in threaded engagement with an inner portion 56 having a bore 58 through which the shaft 34 passes and a counterbore 60 housing the sealing means 62 which is shown as a mechanical seal comprising a rotatable ring 82 fixed to the shaft by a screw 84 and a stationary ring 80. The portion 56 has a flange 68 overlapping the portion 50 and normally sealed thereto by a gasket 70. Leakage between portions 50 and 56 is further prevented by 0-rings 74. A collar 112 is fixed to the shaft 34 adjacent flange 68 and bolts 116 threaded in the portion 50 and sealed thereto by 0-rings 119 have heads 118 which underlie the collar 112. To remove the seal 62, the shaft 34 is first held axially by rotating the portion 56 and the bolts 116 until they engage opposite sides of the collar 112, as in Fig. 3, the flange 90 is then removed and the seal is then slid over the end of the shaft 34 and a replacement fitted. During this time leakage between the shaft and the bore 58 is prevented by a gasket 122 on collar 112. The efficiency of gasket 122 may be tested by removing plugs 126 from test passages 124. If the shaft 34 enters the casing 22 from the top, as shown, and the pressure in the casing is insufficient to raise the shaft, engagement of the collar 112 by the bolts 116 only is sufficient to hold the shaft 34 during replacement of the seal. In the modification, shown in Fig. 3, the shaft cannot be held against axial movement in both directions at once. A collar 154 on the shaft 34 is straddled by flanges 152 and 158 on the inner portion 146 threaded in the portion 138. To hold the shaft axially whilst replacing the seal 62 the portion 146 is rotated by handles 150 in the appropriate direction until either gasket 156 on flange 152 or gasket 160 on flange 158 is in fluid-tight contact with the collar 154. Specification 856,150 is referred to.
