Abstract: 644,872. Rail joints; rotary elevators. MORGAN, M. F. Aug. 1, 1947, No. 20971. Convention date, Feb. 13, 1942. [Classes 78 (i) and 104 (ii)] [Also in Group II] In a sintering machine of the conventional type comprising fixed upper and lower runs connected by end bends, and means for propelling pallets around the curved end from the lower run to the upper run, adjustment of the length of the runs to compensate for wear of the ends of the pallets is provided by a curved discharge-end run which is movable toward and away from the adjacent ends of the upper and lower runs, filling-pieces being provided to enable the runs to be continued across the gap, which is adjusted so that a pallet can be added to those on the track, or one removed therefrom, to maintain a predetermined spacing between pallets. Fig. 3 shows the ends of the rails 2 of the upper run and of rails 4 of the lower run. The curved end run which is adjustably movable on the frame of the machine consists of a pair of tracks 25 and guards 26. Tracks 25 are aligned with the ends of the rails 2 of the upper run and with guards 5 of the lower run, while the lower ends of the guards 26 are aligned with the ends of rails 4. When a pallet is propelled on to the discharge end-run its wheels run on the rails 25 for part of the length of those rails and then on to part of the length of guards 26. The filling-pieces 30, Fig. 6, of the upper run consist preferably of sheet-metal plate with upstanding lugs 32 that are aligned with the tracks 2 and 25 and serve as continuations thereof, a bolt-hole being provided towards each end of the plate 30 to receive a clamping bolt passing through the assembled plates into part of the frame of the machine.

Title: Pulse communication system
IPC: H04J3/06
Filed: 1956-07-06
Abstract: 800,660. Automatic control systems for electrical delay lines. STANDARD TELEPHONES & CABLES, Ltd. July 6, 1956 [July 8, 1955], No. 21003/56. Class 38 (4). [Also in Groups XL (b) and XL (c)] In a pulse-phase-modulated, time division multiplex communication system of the kind in which at both the transmitter and the receiver the successive channels are controlled by gating signals from delay line distributers, the electrical length of the delay line at the receiver is automatically controlled in response to the timing of synchronizing pulses from the transmitter. The delay lines also form the frequency determining networks of phase-shift oscillators. Receiver.-A delay line 46, Fig. 1B, is coupled between anode and control grid of an oscillator valve 47 by means of a transformer 48. The transformer 48 is designed to effect a 180 degrees phase shift over a wide frequency band so that the length of the delay line 46 determines the frequency of oscillation. In order to maintain the oscillator 47 in synchronism with the transmitter, synchronizing pulses from the transmitter are separated at 40 and applied to a phase comparator 53 together with the output of the oscillator 47. A deviation varies the D.C. through windings 55 on the ferromagnetic cores of the delay line inductors to correct its electrical length. In a modification. Fig. 2 (not shown), the oscillator is omitted and the separated synchronizing pulses are applied to the delay line. The electrical length of this line is controlled by applying signals from both ends of the line to a phase comparator the output of which controls the D.C. through control windings as above. The length of the line is normally equal to the time interval between successive synchronizing pulses so that a pulse which has traversed the line should coincide with the arrival of the next incoming pulse. Lack of coincidence effects control of the D.C. windings in an unspecified manner.
