Title: Apparatus for Regulating the Tension of a Strip between Roll Stands in a Continuous Rolling Mill
Inventor: DEMCHENKO ANATOLY TARASOVICH
IPC: B21B37/50
Filed: 1968-03-06
Abstract: 1,165,475. Rolling. INSTITUT CHERNOI METALLURGII. 6 March, 1968, No. 10858/68. Heading B3M. The tension of a strip being continuously rolled is regulated between successive stands by hydraulically operated looper arms 17. The force exerted by the arms decreases progressively as the strip is rolled between subsequent stands. A common accumulator 1 supplies all the looper cylinders 2 through a pressure main 3, the accumulator being supplied with hydraulic fluid from a pump 6, and with nitrogen from cylinders 15. In the operating position of each arm 17, as shown, the differential area of the piston 20 produces a force urging the arm upwardly. By varying the differential areas of subsequent pistons (by changing the piston rod diameters) the ratio of forces produced by the arms is determined. The position of the arms 17 can be used to control the pressure in the accumulator. Operation of solenoids 18 or 19 causes lowering or raising of each arm during, for example, a strip threading operation.

Abstract: 982,925. Removing lint and dust from looms. GRINNELL CORPORATION. March 25, 1963, No. 11655/63. Heading F4X. An apparatus for collecting lint and dust on looms comprises a movable screen shown as a continuous belt 10, disposed under the lintproducing parts of the warp and weft in the loom, and carrying the deposited lint to a manifold 20 wherein a vacuum is maintained for removing the lint and dust from the screen, the manifold 20 being dis posed at the edge of the screen. Each loom requires two such apparatus, at the back and front of the loom, respectively. In one embodiment described and as shown, for use at the back of the loom, the belt 10 passes over the loom whip roll (not shown), and about a roller 16, and the belt is moved by the movement of the warp threads over the whip roll. Placed under the roller 16 is the manifold 20, the opening 20b of which is largely blocked by the roller 16, leaving a narrow entry 22. The manifold is connected by flexible conduits (not shown) to a suction pump, and lint is collected from the belt 10, as it passes over the roller 16, by the air sucked through the slot 22, any lint remaining being scraped off by the lip 20e, with which the belt is in sliding contact. In one embodiment described (Figs. 7 and 8, not shown) for use in the front of the loom, the belt is positioned to rotate in a direction transverse to the loom. Methods are also given of slack adjusting arrangements for the belt.

Title: Record perforator
IPC: H04L17/20
Filed: 1962-03-27
Abstract: 930,953. Selective punching machines. BURROUGHS CORPORATION. March 27, 1962 [April 3, 1961], No. 11685/62. Class 31 (2). The subject-matter of this Specification is contained in Specification 930,952 but the claims are directed to a control circuit by means of which the main drive-shaft can be constantly rotated or intermittently driven. The control circuit, Fig. 2, is supplied with current by means of a circuit, Fig. 2A, which provides a D.C. potential between output terminal 136 and ground terminal 137. The main drive-shaft is coupled to motor 131. In the circuit of Fig. 2, the closing of switch 140 initiates a tape feed operation in which each of the solenoids 21, 27 controlling the punch interposers will be energized as well as one, the other, or both of the solenoids 97, 107 controlling the feed pawl which are mounted on the same shafts as the tape feed sprocket-wheels. The closing of switch 140 applies the positive potential of terminal 136 to relay 161 which closes contacts 161A. The potential of terminal 136 is thereby applied to a first set of contacts 143. When cam 145 secured to the main drive-shaft closes the contacts 143, relay 146 will be energized. Contacts 146A provide a holding circuit for relay 146. Contacts 146B are connected with a second set of contacts 147 controlled by a cam 148 secured to the main drive-shaft. When the contacts 147 are closed, the positive potential will be applied to a common bus 149. Potential from bus 149 will be applied across diodes 150 to common terminal strips 151 to which the solenoids 21 are connected. As a result, the punch interposers will be released to enable a bail operable by cams secured to the main shaft to move the punches through one or both tapes. Switches 153, 154 can be manually set so that one, the other, or both of the solenoids 97, 107 will be energized in response to the potential applied to bus 149. The perforator can be controlled by an accounting machine having a read-out and encoding mechanism 169. For this purpose, switch 170 is closed. As a result, contacts 170A complete the circuit from bus 149 to the accounting machine, contacts 170B are closed and contacts 170C are opened. The switches 153, 154 are controlled by separate keys on the accounting machine. The control circuit is also adapted for use with a typewriter having read-out switches 180. A manual switch 181 is closed to render the typewriter operable for controlling the perforator and such operation of switch not only connects bus 149 to the switches 180 but also closes contacts 181A. Thereafter, the operation of a key on the typewriter will cause contacts 182 to be closed.
