Abstract: Abstract of the Disclosure A carrier telephone system useful in serving a large number of subscribers by delta modulation over a digital transmission facility having a predetermined bit rate capacity.  The system comprises a central office control terminal, one or more remote terminals and an interconnecting digital transmission facility.  The subscribers are connected to the remote terminals by wire pairs.  The control terminal interfaces with the central office switching machine and provides a line appearance for each subscriber connected to the remote terminal and controls the assignment of transmission channels to active subscribers.  The system includes a full access non-blocking concentration switching subsystem.  The system provides for a normal mode of operation where a fixed number of transmission channels are available for assignment to active subscribers.  In this mode the transmission channels operate at a fixed bit rate.  When all transmission channels have been Assigned to sub-scribers, the system operates in an elastic mode which adds or deletes additional transmission channels as required by the subscriber traffic.  As transmission channels are added or deleted while in the elastic mode, the bit rate for all transmission channels changes accord-ingly.  The carrier concentrator system and method is also useful in providing interoffice telephone trunks between a hub central office and one or more tributary offices.

Title: Method and apparatus for generating digital dual frequency signals
Inventor: EDWARDS JOHN D
IPC: H04Q1/457
Filed: 1976-02-18
Granted: 1980-01-22
Abstract: ABSTRACT OF THE DISCLOSURE                  A dual tone multiple frequency digital tone generator for a PCM/TDM electronic telephone system.  A digital representation of a dual tone signal is generated from a multi-bit command character by determining the phase angle of two frequencies specified by the command character relative to an independent time reference signal, converting paired phase angles to amplitude signals representative of the amplitude of a sine wave having each calculated phase angle, and summing the amplitude representations to generate a value corresponding to the digital representation of the frequency pair at that particular instant.  Individual phase angles are calculated by generating a multi-bit digitial character corresponding to the phase angle of a sinusoidal reference signal of the particular frequency.  This character is preferably generated by multiplying a multi-bit digital character having n-bits representing the fractional part of the number of seconds elapsed from some reference time by a multi-bit digital character having m bits representing the frequency of the sinusoidal signal, m and n both integers.        The resulting m + n bit product consisting of an m-bit integral part and an n-bit fractional part is examined and the p most significant bits to the right of the decimal point are selected, p being an integer. The value of n determines the accuracy of the product relative to the absolute value of the phase angle, while the value of p determines the resolution of the phase angle representation.        Both n and p are preselected in accordance with the required accuracy of the frequency representation.

Abstract: SEAT BELT RETRACTOR WITH WINDING PREVENTION MECHANISM         Abstract of the Disclosure:         A seat belt retractor has a belt reel with a restraint belt attached thereto and biased in the belt winding direction of rotation by a windup spring which tensions the belt in a restraining position about the occupant and winds the belt to a stored position on the reel.  A detent mechanism comprised of a pawl and ratchet normally permits belt winding reel rotation by the windup spring and is movable to a detenting position wherein the pawl engages the ratchet to hold the belt in a nontensioned restraining position about the occupant.  A control mechanism comprised of a control disc and a blocking disc operate the pawl between the detenting and undetenting positions in response to rotation of the discs through less than one revolution between one limit at which rotation in the unwind-ing direction is stopped and another limit at which rotation in the winding direction is stopped.  The pawl coacts with the discs to define the limits of rotation.  A friction clutch acts between the discs and the reel to rotate the discs as a unit with the reel and permit continued rotation of the reel after the discs are stopped at their respective limits of rotation by the pawl.  A selected operator actuated means such as the vehicle door is operably connected with the pawl to move the pawl out of its rotation limiting coaction with the blocking disc and control disc so that the discs are freed for unitary rotation with the belt reel, thereby terminating the relative rotation between the discs and the reel so that the windup spring need not overcome the frictional impediment normally exerted on the reel by slippage of the friction clutch.
