Abstract: ABSTRACT OF THE DISCLOSURE   Disclosed is a fault location system for a repeatered PCM trans-mission system.  A first means transmits through a repeatered transmission line, fault location codes based on pseudo-random codes.  The fault location codes are capable of code conversion into codes having two states controllable in response to a repeater-designation frequency signal, one of said two states having the occurrence probability of digit "1" equal to k sufficiently greater or smaller than 0.5 while the other state has the occurrence probab-ility of digit "1" equal to (1-k).  A second means is disposed at a designat-ed repeater for receiving the fault location codes including repeater trans-mission errors.  A third means is provided for extracting a component of the repeater-designation frequency signal from the received fault location codes by means of a fault locating circuit built in the repeater and including an additional code-converter.  A fourth means receives the extracted repeater-designation frequency signal component at a transmitting point of the fault location codes, whereby the fault location for the repeatered transmission line is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to magnetically operated locks.  In prior art magnetically operated locks when a key containing a magnet is placed on the enclosure, the arm is lifted from the locking tab and the magnet in the key is then moved to pivot the locking arm.  This arrange-ment is relatively expensive and may be operated by un-authorized personnel.  Other magnetically operated locks often require key magnets arranged to both attract and repel corresponding locking elements.  The arrangement of lock-ing elements for both attractive and repelling movement contributes to the expense of magnetically operated locks while the use of an access opening often enables the pur-pose of the lock to be frustrated.  The present invention provides a magnetically operated lock for a coaxial switch in which a slide member is operated in opposite directions by a slide magnet in a key to connect an incoming coax line to either another coax line or to ground.  The key has a configuration corresponding to the lock housing and when associated with the lock housing, automatically positions a plurality of spaced magnets in the key to operate a plurality of pins in opposite directions to unlock the slide.  Removal or disengagement of the key from the lock housing enables the pins in the lock to engage the slide and lock the switch in either position to which it is operated.

Abstract: ABSTRACT OF THE DISCLOSURE         An error corrector circuit for correcting a tape timer in a video tape recorder/reproducer (VTR) having a multiple frequency control track, wherein a selected control track frequency is separated from the composite frequencies via commutating filter means capable of following frequency variations caused by variable tape speeds.  The resulting filtered control track signal of selected frequency is phase compared with a tach clock signal of similar frequency obtained from the capstan tachometer.  In the absence of slip, creep, tension variations, and other speed errors caused by playing the tape on different devices, there is no phase difference between the compared signals, which are thus phase locked to-gether.  Any phase deviations between the filtered control signal and the tach clock signal are detected and fed back to correct the tach clock signal so that it accurately represents the passage of tape past the VTR head means.  A television frame rate pulse output derived from the corrected tach clock signal is fed to the tape timer of the VTR.

Abstract: DYNAMOELECTRIC MACHINE CORE AND COIL ASSEMBLY     Abstract of the Disclosure A dynamoelectric machine core and coil assembly characterized by having a separately insertable conformable side filler, such as resin impregnated fiber glass provided with a plurality of ridges of an electrically semi-conductive, pressure-deformable elastomer bonded to one side thereof.         In the assembly the conformable side filler is compressed between the side of a coil-receiving laminated core slot and the relatively smooth sides of coil windings mounted in the slot.  As thus compressed, the side filler forms a good thermally conductive path between the somewhat irregular coil sides and the core to thereby prevent undesirable temperature rises.  The side fillers also prevent insulation-destroying vibration of the coils in the slots, and due to the semi-conductive nature of the side fillers, they prevent the formation of corona across any voids that might exist between the sides of the coil insulation and the sides or the coil-receiving slots.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed herein is a shock- or vibration-sensitive sensor for use as a switch in a security system, comprising a substantially toroidally-shaped body having an inwardly-facing surface area and an electrically conductive outwardly-facing surface area. The body is normally loosely seated upon at least a pair of contact elements within a housing.  The contact elements cooperate with the conductive outwardly-facing surface area of the body to normally close an electrical circuit which will be interrupted whenever the body loses contact with at least one of the contact elements due to bouncing motion accompanied by displacement caused by shock or vibration applied to the sensor.  A center post loosely extends through the aperture in the body, the center post limiting the range of possible displacement of the body by contac-ting the inwardly-facing surface area of the body upon shock- or vibration-induced displacement of the body.  Thus, the center post prevents the conductive outwardly-facing surface area of the body from con-tacting any of the inner surfaces of the housing.         In accordance with a specific aspect of the invention, sharp, pointed contact elements are used which penetrate any nonconductive film if present on the conductive outwardly-facing surface area of the body whose mass is of sufficient magnitute to cause such penetration.

Abstract: ABSTRACT OF THE DISCLOSURE   This invention relates generally to a method and composition for sterilizing plastic hydrophilic or "soft" contact lenses.  One of the problems connected with soft contact lenses is the method of their steri-lization and cleaning.  The very property of the hydrophilic soft lenses which allows them to absorb up to 150 percent by weight of water also allows preservatives which might otherwise be used for cleaning and sterilization to be absorbed and even concentrated and later released when the soft contact lens is on the eye.  It has now been discovered that contact lens generally and especially plastic hydrophilic (soft) contact lenses may be effectively sterilized and used without deleterious effect to the lenses or the eyes of the user by the present invention.  The sterilizing solution of this invention will not be absorbed by the lenses in significant quantities.  In addition, to the extent, if any, that the sterilizing solution of this invention is absorbed by the lenses, it will not harm the lenses or the eyes of the wearer.  This invention also solves the shelf life problem.  According to the invention, there is provided a method for sterilizing contact lenses comprising contacting a contact lens for a period of time sufficient to sterilize the lens with a substantially isotonic, aqueous composition comprising a microbicidally effective amount of an ene-diol compound and a minor, catalytic amount of a catalytic metal compound.
