Abstract: 1395846 Shearing fabrics RIGGS & LOMBARD Inc 23 July 1973 35066/73 Heading DIS  A seam detector 10 for a running fabric web 14, e.g. for use with a shearing machine 12, comprises a relatively fixed first member 44 engaging one side of the fabric 14, a relatively fixed sensor 52 spaced from the member 44 and engaging the other side of the fabric, a second member 40 opposite the member 44 and engaging the other side of the web, a third member 42 opposite the sensor 52 and engaging the one side of the fabric, and means 32 connecting the members 40, 42 for mutual movement towards and away from the member 44 and the sensor 52 according to the thickness of the fabric 14. As shown, a shearing machine 12 comprises a shearing revolver 20 having helical cutting elements 22 thereon and which is mounted parallel to a rest 16 and a coacting ledger knife 18. The revolver 20 and the knife 18 are mounted on a bracket 24 movable about a pivot 26 to allow passage of a thickened seam 28. The detector 10 comprises a bracket 32 pivotable about the axis of a shaft 34 and carrying rollers 40, 42. Idler rollers 44, 46 are mounted between fixed plates 30. A seam sensor 52 is mounted between the plates 30 by a cross-bar 50 and comprises a roller 54, Fig. 3, which is mounted on a yoke 56 and which, on passage of the seam 28, is moved back so that a stem 58 on the yoke 56 depresses a spring-loaded actuator 60 of a microswitch 62 so that a pneumatic or hydraulic cylinder 64, operated by a solenoid actuated valve 68 connected to an adjustable time delay 72, pivots the bracket 24 to lift the revolver 20 and the knife 18 to allow the seam to pass. A number of sensors 52 may be mounted across the fabric to detect skewed, bowed or other irregular seams. A tension device 74, having an adjustable spring, acts on the bracket 32 to cause the rollers 40, 42 to engage the fabric. Any thicker fabric passing through the machine causes the roller 40 to bias the bracket 32 about the shaft 34 so that the roller 42 is moved a corresponding distance from the sensor 52.

Abstract: 912,548. Typewriters. GAUNT, J. G. (Pacific Industries Inc.). Oct. 22, 1959, No. 36886/59. Class 100 (4). In a mechanism for controlling a typewriter a member 20, Fig. 1, normally in its extreme left-hand position as shown, is permitted to move a distance to the right corresponding to the particular combination of four solenoids 40a, 40b, 40c and 40d that are energized to correspondingly position a typewheel 24. Printing is then accomplished by the downward movement of a rubber cylinder 30 on to paper and ink ribbons 26 and 28 respectively. The four solenoids 40a, 40b, 40c and 40d when energized permit displacements of 1, 2, 3 and 4 increments respectively and these are summed to give the resulting displacement of the member 20. The solenoid 40c, for example, when energized pivots a lever 88 about its end 90 to thereby raise a locking projection 82 on a link 45 from a recess 85 on a link 46, and this permits the link 46 to move two increments with respect to link 45. Link 45 and two other links 47 and 48 are similarly permitted limited relative displacements by the other solenoids, and these displacements are summed when the member 20 is pulled as far to the right as it will go.
