Abstract: 487,623. Measuring fabrics &c. MENSCHNER, J. April 17, 1937, No. 11044. Addition to 431,888. [Class 42 (ii)] [Also in Group XVI] In a machine for measuring running webs according to the parent Specification in which a feed roller is positioned between a pre-tensioning device and a draw roller appropriate to the measuring operation, which feed roller feeds the web faster than the draw roller can receive it and in which a feeler roller connected with the drive of the feed is disposed on the web, the lever carrying the feeler roller is under an automatically variable load, e.g. a spring pressure, corresponding to the displacement of the roller and is so connected by suitable means with the feed roller that the turning movement of the latter is regulated by the of the feeler roller, which is independently varied according to the flexibility of the web. The web passes over pre-tensioning bars 2, Fig. 1, feed roller 3, feeler roller 15 and draw roller 4. The feeler roller is carried by a lever 22, pivoted at 48 and counter-weighted adjustably at 46, and movable against the increasing pressure of a spring 49. The lever is connected by a spring 51 to a bellcrank lever 52, which tensions a braise-strap in contact with a drum 31. A gear 60, Fig. 2, is secured to the drum 31, and a driven gear 55 engages the gear 60 through a, pair of gears 58, 57 secured, to a pin carried by an arm fast on the shaft 20 of the rolller 3. The displacement of the roller 15 thus controls the drive of the roller 3 and the increasing pressure of the spring 49 enables the roller 15 to take up a different equilibrium position for webs of different flexibilities, so that all are measured in the desired stress-free condition.

Abstract: 1414229 Photo-electric registration control J BOBST & FILS SA 7 March 1973 [13 March 1972] 11157/73 Heading G1A [Also in Division B6] Apparatus for obtaining a reading window pulse for assisting in the control of registration of material in a printing press comprises a pulse generator adapted to generate a starting pulse for each revolution of a printing cylinder, means for producing a control signal representative of the speed of travel of the material being printed by said press, and a timing device connected to receive said starting pulse and said control signal for producing a window pulse in response to said starting pulse, said window pulse having a duration which is a function of the speed of travel of the material being printed and which is independent of the diameter of said cylinder. In the described embodiment a cam 2 and transducer 5 is employed to produce a predetermined pulse during each cycle of the cylinder. This pulse transmits on line 16 to timing devices T1, T2 which generate at their outputs A, B waveforms A, B of Fig. 4. Timing device period of Tl is twice as long as T2 so that the pulse produced by the latter has a trailing edge at the midpoint of pulse produced by T1. A monostable device M is connected to T2 to produce on line C a short pulse coincident with the trailing edge of the pulse produced by T2. This occurs in the midpoint of pulse produced by T1. The pulse of T1 is equivalent to the window pulse 8 of Fig. 2 while the pulse produced by device M is equivalent with the reference pulse 9 of Fig. 2. A line 17 is connected to Tl and T2 and functions to regulate the time interval produced by T1 and T2 in accordance with the speed of operation of the press. A manually adjustable potentiometer P1 is connected via a line 18 to units Tl and T2 and serves to render the length of the pulses produced thereby manually adjustable as desired. Fig. 5 (not shown) illustrates a diagram of the apparatus shown in block form in Fig. 3.
