Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a chair leg and a protective cap therefor.  The cap is adapted to fit over and be secured to the end portion of the chair leg.  The cap has a small protrusion on the inside top surface which fits into and is secured by an aperture in the upper surface of the chair leg.  The cap has also an aperture in the bottom surface which fits over and is secured by a portion of the socket which extends below the plane of the lower surface of the end portion of the chair leg.          This new structure reduces significantly the cost of pro-duction by eleminating the need to grind and buff the end portion of the chair leg yet produces a smooth, safe and acceptable end for the chair leg.

Abstract: VOICE RECOGNIZING TELEPHONE CALL DENIAL SYSTEM ABSTRACT OF THE DISCLOSURE          A call denial apparatus for denying a subscriber's access to a trunk.  A voice recognizer is connected to the trunk, and receives a password spoken by the subscriber.  The apparatus then receives digits dialed by the subscriber over the subscriber's line and carried by the trunk, matching them with one or a series of digits stored in a memory.  In the event the password or subscriber's voice matches a predetermined password or voice, the digits which are dialed are passed over the trunk.  However in the event that the password or voice does not match the predetermined password or voice, and in the event a predetermined one or group of digits are dialed which match a prohibited digit or group of digits stored in the memory, the trunk is split, and the subscriber is restricted from further access to the trunk.  Thus only predetermined subscribers have full access to the trunk, and other subscribers have access only for limited services, or for no services.  The voice recognition design allows different subscribers to have different classes of service, and for the first time does not tie trunk restriction to a subscriber's line, but to an actual subscriber.

Abstract: ABSTRACT      Male and female parts are included in a coupling device which is provided with locking members for said parts.  The locking members comprise a lock nut which is adapted to be fitted on the female part and a locking ring which can be inserted between two opposite locking surfaces on the male part and the locking unit to prevent mutual pulling-apart movements between the male and female parts. An opposing member is adapted to impart to the locking unit a first distinct longitudinal displacement position in relation to the female part.  In this longitudinal displa-cement position, at least one sealing ring is inserted between the male and female parts and the male park is comparatively loosely suspended in and sealed with respect to the female part by said sealing ring.  The opposing member is also adapted to yield to the locking unit when a certain longitudinal displacement force or moment is imparted to this by the opposing member, for which the locking unit assumes a second longitudinal displacement position.  In the latter position, a front sealing surface on the male part cooperates with a seat provided in the female part to achieve a rigid connection between the parts and a reliable sealing between said parts which may be additionally sealed by one or more sealing rings.

Abstract: RESETTABLE LOCK ASSEMBLY        ABSTRACT The present invention relates to a resettable single-barrel single-plug cylindrical two section lock assembly.  Prior art locks have either used two barrels and been resettable-or used one barrel and been non-resettable.  The disclosed single-barrel resettable lock can be more economically produced than conventional two-barrel locks.  The lock of the invention is intended to be operated and reset by three different keys.  One key (#1 key) is used to turn the lock to a reset position.  One of the other two keys (#2 key) normally operates a first section of the lock and the other of the other of the two keys (#3 key) operates a second section of the lock which is independent of the first section.  Either section may be reset by turning the lock with the existing (#1) key to the reset position, with-drawing the existing (#1) key, and inserting and turning the lock back to its normal operating position by a new key, either a #2 or #3 key, depending upon which section of the lock is being reset.

Abstract: ABSTRACT          This invention relates to a method for ascertaining for one or more targets information about the positions and velocities of the targets by using at least one transmitter and at least one receiver stationed at known relative positions in a medium having a known signal propagation velocity.  Each transmitter transmits concurrently at least one component signal of known initial time consisting of at least two member signals, the time intervals between member signals being initially known.  The concurrent component signals are separable.  Each target reflects each component signal to each receiver.  From each received signal the component signals are separated.  From the component signals member signals reflected by each target are identified.  For each identified member signal its transit time between transmitter and receiver, and the interval times between member signals of each component signal reflected by each target are measured.  Target velocity components from each measured time interval are produced using the known initial time interval value.  Each measured transit time in each component signal is corrected for determined relative motions between the transmitter, receiver and targets.  The corr-ected transit time measurements in the component signals and the known signal propagation velocity are used to make target range determinations.

Abstract: Abstract of the Disclosure A method of synchronizing a digital radio pager receiver with incoming digital data signals.  At switch-on the receiver first attains a "course" bit synch during the first quarter-word period and then a "fine" bit synch during the next half-word period. The receiver then examines incoming data bits to determine simultaneously (a) whether valid data is being received and (b) whether the incoming data contains a preamble sequence. If either determination is successful the incoming data is then examined to determine whether it contains a synchronizing word or an address word.  The synchronization and address word determination is also carried out while bit synch is obtained and the valid data/preamble determination is effected.
