Title: Signalling device for delivery of messages - has timing circuit and counter controlling AND=circuits to which information signals from pick=ups are applied
Inventor: WUNDERLE HELMUT STEFAN KASPAR
IPC: G08B25/01
Filed: 1977-02-16
Abstract: The device is a monitor, position signaller or position indicator, and delivers messages depending on presence or absence of information signals at the outputs of several signal pickups. Messages are stored on a recording medium consecutively, separated by pauses. They correspond to different information signals. Output of a reproduction head (30) is connected through a switch contact to a transmission line, and also through a timing circuit (1) to the clock input (28) of a counter (3) with several outputs (A1-An). The latter, controlled by clock pulses deliver consecutively a counter signal. After the end of each reproduced messages the timing circuit (1) produces a pause no longer than the pause between messages on the tape, and then delivers a clock signal to the counter (3) input (28). Each counter output (A1-An) and each output of information pickups (I1-Un) is connected to a first input of an AND circuit (U1-Un), whose outputs are connected to a device operating the switch contact (a).

Patent DE-2713994-A1 (DE)
Inventor: FISCHER HERMANN
IPC: B41F21/10
Filed: 1977-03-30
Abstract: A number of sheet grippers is fixed on two gripper support elements extending parallel to the leading edge of the sheet over the width of the printing machine, of which gripper support elements a gripper support shaft bears the gripper fingers and a gripper rest rail (19, 21) bears the gripper rests for the gripper fingers and is capable of slightly deforming the printing sheet (77) at its leading edge by moving at least one of the two gripper support elements in a direction running approximately perpendicular to the plane of the printing sheet. The device is intended to allow satisfactory processing even of very soft types of paper which are flexible perpendicular to the plane of the sheet and in which deformations of the sheet which radiate from the grippers customarily occur, which have a corresponding effect on the printing pattern and can lead to the formation of radiating folds. According to the invention this is achieved in that, at least in the central region of the two gripper support elements, their spacing can be enlarged by a predetermined amount, the sheet grippers can then be moved from the central region by a given distance towards the respective printing machine wheel, and the spacing of the two gripper support elements can finally be reduced again by the predetermined amount. <IMAGE>
