Abstract: ABSTRACT           In a video disc players, a recorded composite signal, recovered during disc playback, includes a chrominance signal component buried in the midband of the accompanying luminance signal component.  The player includes video processing circuits converting the recovered signal to an output composite signal in which the chrominance signal component occupies a higher frequency band, and employing the step of heterodyning the recovered composite signal with oscillations at a nominal frequency of fs + fs' (where fs is the color subcarrier frequency of the output, and fs' is the buried color subcarrier frequency of the disc signal).  To stabilize the output chrominance signal component against spurious frequency variations accompanying disc playback, a phase locked loop (PLL) system is established to cause the fs + fs' oscillations to track the disc frequency variations.  The PLL system employs a voltage controlled oscillator (VCO) operating at a nominal frequency of ? fs - fs', and responding to the output of a phase detector, comparing the synchronizing burst component of the output chrominance signal with the highly stable output of a reference oscillator operating at fs.          The VCO output is heterodyned with oscillations at ? fs, derived from the reference oscillator, to provide the desited oscillation output varying about fs + fs'.          "Sidelock" under disc playback initiation conditions is avoided by limiting the hold-in range of the VCO.  A sweep voltage input to the VCO is supplied under out-of-lock conditions to enable phase lock acquisition.  Upon achievement of phase lock, sweep generation is disabled, and sweep voltage sweeps back to mid-range value with normal slope.     Sample-and-hold circuitry is employed in error voltage development, to enable PLL system to hold within rapid pull-in range during lengthy signal dropouts.    -1a-

Title: Coupling ring assembly

IPC: H01R13/621
Filed: 1975-04-23
Granted: 1979-01-09
Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to electrical connector couplings and particularly to a coupling for providing threaded engagement between electrical connector shells.          Electrical connector apparatus usually include a coupling ring rotatably mounted on one shell and arranged for threaded engagement with another shell.  Occasionally vibrational forces loosen the coupling ring from the shell.          Prior arrangements for resisting loosening incorporate smoothly contoured teeth fixed on a coupling ring and engaging similarly contoured teeth on one connector shell.          While this arrangement holds the members against loosening, it is expensive and difficult to operate.  Other prior arrangements incorporate spring detents, but disassembly cannot be provided without auxiliary means for disengaging the detents.  The present invention avoids the above prob-lems by providing a ratchet washer keyed to the coupling ring and interposed between a wave washer and a flange on one connector shell.  The ratchet washer has axially ex-tending ratchet teeth keyed to the ring for rotation therewith.  The ratchet teeth are biased against teeth on one shell.  Each tooth on the shell has a cam face for engagement with a similar cam face on each tooth on the ratchet washer.  A stop face is also formed on each tooth and the stop faces engage for providing a large resistance to rotation of the coupling ring in the loosening direc-tion.

Abstract: FUSING ELEMENT FOR A CIRCUIT PROTECTOR          Abstract of the Disclosure The  fusible  element  of  an  electric  fuse  has  a  first electrical conducting path, a second electrical conducting path in electrical parallel relation with the first electrical conducting path, a weak spot in the first electrical conducting path which can respond to a potentially-hurtful overcurrent to fuse and thereby form a first arc in the first electrical conducting path, and a weak spot  in  the  second  electrical  conducting  path  which  is longitudinally displaced from the weak spot in the first electrical conducting path and which can respond to that overcurrent to fuse and thereby form a first arc in the second electrical conducting path.   The weak spots in the electrical conducting paths form primary arcs in those electrical conducting paths as they fuse; and one important function of those primary arcs is to establish the point at which the rate of  rise of  the overcurrent starts  to diminish, while another important function of those primary arcs is to  burn  the  adjacent  portions of  the  respective  electrical conducting paths.   When enough of the cross sections of those adjacent portions have burned to enable those adjacent portions to fuse, secondary arcs will develop at those adjacent portions; and an important function of those secondary arcs is to provide the desirable  current-interrupting characteristics  that  the series-arranged weak spots of a fusible element can provide when they fuse simultaneously.   The cross sections of the weak spots are made relatively small; and hence the primary arcs which form as those weak spots fuse enable the electric fuse to establish a relatively low point at which the rate of rise of the overcurrent starts to diminish.     The  current-interrupting  characteristics  of  the secondary  arcs,  which  form  as  the  adjacent  portions  of  the respective electrical conducting paths fuse, will co-act with the relatively low point, at which the rate of rise of the overcurrent starts to diminish, to quickly reduce the current to zero.
