Title: Improvements in or relating to remote control systems
IPC: H04L7/00
Filed: 1937-07-10
Abstract: 492,705. Synchronous movements. STEVENS, A. H. (International Business Machines Corporation) July 10, 1937, No. 19211. [Class 40 (iii)] Timed single impulses of definite periodicity release a controlled element 13 from a definite phase position 3, and thereafter actuate means 36 for correcting the phase of the controlled element. To start sending the signals a switch 190 is moved to the S position to energize a release relay 15 and a multiple switch relay 160, which are subsequently held by a current through a resistance 163. When released by the armature 16, the brush arm 13 is rotated through a friction drive from a motor 99 and transmits a signal each time it passes a segment 1. Owing to the artificial line AL the signals are balanced out in the receiving transformer 32. At the receiver, the signals in the secondary 34 trip an electronic relay 132 which operates the release relay 15 and is then cut off by a relay 170. Delays in the release relay and the clutch mechanism neutralize the lead of the receiving brush arm. Succeeding signals therefore arrive when the brush is on the segment 1 and energize the correcting magnet 36. If synchronism fails, the brush is stopped on the rest segment 3. The magnet 36 has two poles, and a magnetic bar on a correcting arm of the distributer passes between, or close to, the poles, Figs. 5-12 (not shown). The distributer is driven through a clutch which comprises two adjacent coaxial rolls one on the shaft of the distributer and one on a driven shaft. Except in the position of rest they are both engaged by a double cam on a parallel shaft, Figs. 13-15 (not shown). The speed of the motor is controlled by a resistance shunted by a temperature-compensated centrifugal contact. Minor changes in speed are produced by altering the resistance, Figs. 18-21 (not shown). Type-printing telegraphs. When a key 156 is depressed, it trips a local typewriter, is latched by a universal bar key latch 151 and pushes a rod 150 to operate the associated key switch 157. This connects the key switch bus-bar 138 to the appropriate segment 5, and a strong signal flows through the output transformer 27, when the brush arm contacts with this segment. Received signals trip the electronic relay 132 which energizes the appropriate key magnet 158 through the receiving brush arm. At perfect synchronism the circuit is broken by the cut-off relay 170 before the end of the signal, thus minimizing sparking at the distributer.

Convention date, July 31, 1929. [Class 56.] Rolling.-Relates to the manufacture, in continuous sheets, of patterned, ribbed, or hammermarked glass by rolling. According to the invention, an engraved roller which impresses the pattern on the glass forms the upper one of a pair of sheet-forming rollers, and it can be put in place or interchanged without stopping the rolling machine or the flow of glass from the tank furnace. For this purpose, a movable gate is used to reduce the thickness of the stream of glass flowing from the tank so that a strip of glass continues to pass over the lower roller while the engraved roller is being replaced. The time required for changing can be reduced by using two engraved rollers mounted in a frame in such a manner that they oan be interchanged by a simple movement of translation or rotation.
