Abstract: In a method for simultaneous transmission of two heterochronous binary signals in the form of a single binary signal on a common physical medium, the second binary signal is timed by a bit clock whose period is greater than the minimal duration allowed for a bit of the first signal. For constituting the single binary signal transmitted there is provision for inserting between transitions of the first binary input signal a brief binary level inverting pulse for each bit of the second input signal which corresponds to the same one of the two possible binary levels of the second signal. Each temporary polarity inversion pulse due to the second signal is placed outside a guard area on either side of transitions of the first signal.

Abstract: A method and a machine for automatically handling a flat rectangular sheet, located in a bin, which ultimately grasps two adjacent corners, allowing the rest of the sheet to hang freely, making the sheets ready to be dried, pressed and folded. First, the sheet is grasped in an arbitrary location and dragged until the farthest corner is found. Second, this corner is grasped by a gripper, which is attached to a rail, allowing the sheet to be dragged and shaken until the diagonal corner is located. Third, this diagonal corner is grasped by a second gripper. Fourth, the two remaining corners are separated through the use of a separation guide. Fifth, one of these remaining corners is grasped by a third gripper. Sixth, the first gripper is released. Finally, the sheet is moved, through the use of the second and third gripper attached to independent rails which finally become parallel, to a location where the sheet can hang freely from the two grippers attached to adjacent corners.

Abstract: A detector logic circuit restores the value 0 or .+-.1 of a ternary symbol converted into a signal on five levels 0, .+-.1 and .+-.2 as a result of class 1, type n=2 partial response transmission. Employing only binary logic circuits, it is connected to the output of a comparator which has four thresholds and which delivers a value representing the receive level by four binary signals. Two of these signals indicate positive overshooting of extreme and intermediate positive thresholds. The other two indicate negative overshooting of negative extreme and intermediate thresholds. The circuit delivers the values of the ternary symbols detected in the form of two binary components which are available at the output and stored for the duration of a symbol by two flip-flops. Both are generated by combinational logic devices of similar design utilizing OR and NOR gates.
