Set-off, preventing. - In sheet - delivery mechanism for printing-machines comprising a number of superposed tape supports of the rollerblind type, the sheet passing from one to the other so as to dry the impression before it is finally deposited on the pile-table 24, grippers 16, 17 engage the sheet coming from the machine 9 and hold it during the unrolling of the uppermost support beneath it. The spring-rollers 2, 3, 4 of the tape-supports 14, 18, 22 are carried by a reciprocating carriage and are rotated by the engagement of a sprocket 5 on the roller 2 with a fixed rack, and intermediate gearing 7, 8 between the rollers. Fixed bars 15, 19, 23 disposed alternately on opposite sides of the table 24 have fixed thereto the free ends of the tapes 14, 18, 22 respectively. As the sheet passes from the impression cylinder 9 on to a delivery band 11 it is taken by the grippers 16, 17 on the reciprocating carriage which, at that moment, is adjacent to the cylinder. As the carriage moves away from the cylinder, the tapes 14, 22 are unrolled and the tapes 18 rolled up. The grippers 16, 17 release the sheet at the end of the movement away from the cylinder, and as the carriage returns to its initial position the tapes 14 roll up and drop the sheet on to the tapes 18 which are being unrolled. During the next movement of the carriage, the tapes 22 receive the sheet from the tapes 18, and so on until the sheet is deposited on the pile 24.

Title: Improvements in or relating to telegraph systems
IPC: H04L25/24
Filed: 1931-11-30
Abstract: 393,288. Telegraph systems. AUTOMATIC ELECTRIC CO:, Ltd., Strowger Works,' Liverpool. Nov. 30, 1931, No. 33189. Convention date, Nov. 28, 1930. [Class 40 (iii).] A repeater forming part of a reactance-less circuit comprises thermionic valves and electromagnetic relays so arranged that signals repeated to the outgoing line do not disturb the incoming line. When the normally closed line 1, Fig. 1, is interrupted by a distant transmitter, valve 3 ceases to pass current. Sending-on contact 5b opens and passes on the signal to line 2. In order to prevent consequential interruption at 10b of the sending line 1, a holding-winding 10<1> is provided ; when relay 5 releases owing to the stoppage of valve 3, contact 5a opens and unshort. circuits this winding, which then holds contacts 10a, 10b during spacing, while winding 10 holds them during marks. Break-in signals and call-acknowledgments are effected by interruption of line 2 at the receiving station. This ensures that line 1 shall be broken at 10b when closed at its own transmitter. Transmission from line 2 to line 1 is similarly effected. In a modification. Fig. 2, holding-valves 27, 28 are employed instead of the holding-windings 51, 101. A spacing interruption of line 1 paralyzes repeating-valve 3 and opens contact 5b to send on the signal to line 2 as described above. At the same time by opening contact 5a it renders holding-valve 28 operative so that relay 10 is held-on and line 1 therefore remains closed at 10b while holding-valve 27 remains paralyzed through 10a. When the receiving operator interrupts line 2 to send a break-in signal or acknowledge a call, he paralyzes valve 4 so that when line 1 is sending a marking signal so as to paralyze the holding valve 28 through contact 5a, relay 10 releases and breaks line 1 at 10b to disable the sounder on line 1. In a modification, Fig. 3 (not shown), a single valve serves as repeating valve 3 and holding valve 27, and similarly a single valve replaces valves 4, 28, the opening of contact 5a in the case unshort-circuits a source of positive biassing potential so as to hold valve 4 in the operative state. The coils 16, 22 may be replaced by resistances, Fig. 4 (part not shown). Station circuits. A party-line system may comprise stations arranged as in Fig. 4, where the only impedances in the lime are the resistances 106, 106 and the resistance (corresponding to 16, Fig. 1) at the repeater station (not shown) on line 1. Current is normally flowing when the line is idle. The sending station opens its switch 151 to unshort-circuit its key 105, and the latter, by controlling the potential drop in resistances 106 operates the sounders 114 through valves 107 and relays 112.
