Title: Improvements in or relating to digital message transmission systems
IPC: H04Q11/04
Filed: 1961-12-14
Abstract: 967,643. Pulse code modulation systems; automatic exchange systems. WESTERN ELECTRIC CO. Inc. Dec. 14, 1961 [Dec. 30, I960], No. 44754/61. Addition to 967,642. Headings H4K and H4L. The pulse code modulation system described in the parent Specification in which message information is converted into successive pulse groups each having a predetermined number of message digit spaces and means are provided for transmitting a two-state supervisory or control signal simultaneously under selected signalling conditions by adding a further digit space to each code group exclusive of the message digit spaces and a further two-state control signal by utilizing the least significant digit space of a message signal, is modified in that means are provided responsive to one state of the first two-state signal for removing control of the least significant digit space from the encoder, and means responsive to the other state of the first two-state signal for restoring control of the said digit space to the encoder. In the parent Specification, " on-hook " conditions were signalled from the terminating office to the originating office by a binary " 0 " in the least significant digit place (the seventh) and a binary " 1 " in the additional digit space, and " off-hook " conditions by a random binary " 1 " in the seventh digit space produced by the message signal if the channel was in use and a binary " 1 " as the eighth digit. With the channel not in use noise was relied on to produce a random binary " 1 " in the seventh digit space. If precautions where taken to hold the noise to a low level, during prolonged listening periods this arrangement had the disadvantage of appearing to be " on-hook " since the random " 1 " was not present under these circumstances. By removing control of the least significant digit space from the encoder when the additional digit space is transmitting, a binary " 1 " and allowing control by the encoder when the additional digit space is transmitting a binary " 0," no signal is dependent on the ability of the receiving equipment to distinguish between the random presence of a pulse and the forced absence of a pulse in a given digit space. Thus as shown in Fig. 5, " on-hook " signals are transmitted from the terminating office to the originating office as binary " 0 " for the seventh digit D7 and binary " 1 " for the eighth digit D8, for " off-hook " signals a random binary " 1 " (under control of the encoder) is transmitted in the seventh digit place but is not used in identifying the signal and binary " 0 " is transmitted for the eighth digit. Revertive pulses are transmitted as binary 1 for the seventh digit and a binary 1 as the eighth digit. The encoder at the terminating office receives its seventh digit timing pulse through an inhibit gate actuated in accordance with the conditions detected on the two-wire line at that office.

Abstract: 1,159,540. Spring drum apparatus. PACIFIC SCIENTIFIC CO. 2 Oct., 1967 [12 Oct., 1966], No. 44810/67. Heading B8B. A tension regulator for a pair of cables 11, 11<SP>1</SP> comprises a frame 1, the hub 2 of which drives a controlled member, a pair of sheaves 7, 7<SP>1</SP> turnably mounted via balls 6 on the frame 1 and each providing an anchorage 12, 12' for its associated cable, a plurality of pairs of coil springs 25 carried by the frame for urging the sheaves in opposite directions to effect compensating movements of the regulator and rotary locks 9 responsive to a control force in one of the cables 1111<SP>1</SP> to lock the sheaves for rotation with the frame 1 to effect movement of the controlled member. The rotary locks which are spaced around the frame, each comprise a pinion 9 engaging teeth 8<SP>1</SP> formed on opposing faces of the sheaves 7, 7<SP>1</SP>, a spindle 13 carrying a rotor 15 housed in a bushing 16 in the frame 1 and an extension of the rotor 15 drivingly engaging a spindle 19 of a spring drum. The latter has one end of each of the springs 25 anchored thereto, the other ends being attached to drums 24 mounted via spindles 22, on the frame 1. The springs 25 of the constant force type, maintain a constant tension in the cables 11, 11<SP>1</SP> by causing relative rotation of the sheaves 7, 7<SP>1</SP> via the pinion 9 when slack develops in the cables. A pin 27 on one of the sheaves is engageable by the pinion to limit the overall sheave movement. With the application of a control force to one of the cables 11, 11<SP>1</SP>, the pinion spindle 13 tilts and the rotor 15 frictionally locks in the bushing 16 whereupon the sheaves and frame move together. In another embodiment, Fig. 8 (not shown), the hub of the frame is formed as two cupped portions housing between them coiled springs coaxial with the frame. The two portions which are relatively rotatable, each carry a sheave formed internally with teeth for engaging the pinion of a rotary lock. A surge lock is shown in Fig. 10 (not shown), and may be used in the regulator to supplement the rotary locks. The surge lock comprises a rotor driven from the pinion and having arcuate tapered recesses in which balls ride, the balls also riding in similar recesses in a facing disc which is spring biased towards the rotor. With a surge load in one of the cables, the rotor rapidly rotates and drives the balls up the taper forcing the disc against the spring pressure into toothed engagement with a toothed ring on the frame, whereupon the pinion is locked. Frictional engagement between the disc and frame may be utilized when teeth are not provided.
