Abstract: 1,213,362. Typewriters. INTERNATIONAL BUSINESS MACHINES CORP. 20 May, 1968 [21 June, 1967], No. 23865/68. Heading B6F. In a typewriter in which a single element type head 1 is pivoted for impression by a cam 11 or 15 acting on a follower 17, the cam selected governs the throw of ink ribbon lift vibrator arms 41, 43. For printing in black, cam 11 is selected and on rotation of a shaft 7, to which a sleeve bearing the cams is keyed, the head 1 is pivoted about an axis 21 for impression, and a cam 37 rotates to lift a foot 47a of a slotted flange 47. A pin 55 located in the slot of the flange 47 engages a ribbon lift arm 41 and as the flange is lifted and pivoted about a pivot 49, the ribbon lift arms are lifted to position the upper, black, half of the ribbon between the head 1 and the platen 3. For printing in red, the follower 17 may be moved automatically, by electromagnetically displacing a pulley 31 around which passes a tape 27 connected to the follower, into engagement with cam 15. During such movement, a camming member 23 is also moved, a camming surface thereon effecting counterclockwise rotation of a rod 61 and thereby movement of the pin 55 away from the pivot 49 through links 51, 57. When the shaft is then rotated, the ribbon lift arms 41 are lifted further by the cam 37 to bring the lower, red half of the ribbon into operative position. The cams 11, 15 may have different conformations to apply different impression forces to the type head 1. Further cams may be provided, such as a nolift cam 13, and further cams to vary the impression force. Printing in red can be selected manually by positioning a rod 59 through a detent arrangement 63 to prevent the pin 55 moving to the black printing position.

Abstract: 804,266. Controlling vehicles. DAIMLER-BENZ A. G. Aug. 10, 1956 [Aug. 13, 1955], No. 24622/56. Class 79(5) [Also in Group XXXIV] In a knife-edge bearing mounting for a pedal of a motor vehicle the pedal is held against the knife edge fulcrum by means of two springs which exert oppositely dir ected turning moments on the pedal over a portion of the range of movement when the pedal is depressed. The pedal 10, Fig. 1, having a notch to receive a sheet metal bearing plate 11, is held on a knife edge 12 by two springs 18, 22, the stronger spring 18 aids depression of the pedal 10 since its point of attachment 19 is above the fulcrum 12, the force exerted by spring 22 being increased during depression and returns the pedal to the idle position. The plate 11 has an extension 25 which contacts plate 13 to act as a stop means and has a length, in the direction of the knife edge greater than the width of the pedal in that direction. The linkage 15 of the brake &c. control cylinder 16 is connected to the pedal by a pivot joint 17. In an embodiment, Figs. 2, 3 (not shown), two pedals disposed side by side on a common knife edge, are mounted as in Fig. 1 but the point of attachment 19 of spring 18 is below the fulcrum 12 in the idle position, thus in operation it helps spring 22 to oppose depression of the pedal but after passing through the dead centre position it will oppose spring 22 as in Fig. 1 and aid depression. The pedals may be pendant with a compartment plate as a knife edge or may be upright with the floor plate as a knife edge.
