Abstract: Abstract of the Disclosure A key  holder  is disclosed which  comprises  a substantially planar body portion, a substantially circular ring having an open gap therein and rotatably mounted in substantially coplanar relation on the body portion, and a resilient tongue on the body portion.  The ring is rotatable between a closed position wherein the open gap faces inwardly toward the body portion, and an open position wherein the open gap faces outwardly to permit the insertion of a key or the like on the ring.  When the ring is in the closed position, the tongue normally extends into the gap to prevent the  ring  from being rotated.   However,  the  tongue  is resiliently deflectable away from the plane of the body portion to permit the ring to be rotated to the open position.

Title: Scallop eviscerating machine
Inventor: CHOUINARD JOSEPH R C
IPC: A22C25/14
Filed: 1987-06-18
Granted: 1991-04-16
Abstract: ABSTRACT     Disclosed is apparatus for eviscerating fresh scallops immediately after they have been shucked from the shell.  The apparatus cleanly strips membrane, roe and entrails from the edible adductor muscle without causing damage to the latter.  No ageing, chemical or heat pretreatment is required.  The apparatus includes a feed hopper which meters product flow single file onto one end of a set of two horizontal, counterrotating pinch rollers.          A horizontal open bottom trough directs and contains the scallops on the top surfaces of the rollers.  The rollers are critically sized and knurl textured and supported in rolling contact so as to nip and downwardly strip off soft entrails and membrane but support the firm cylindrical meat (muscle tissue).  Water sprays and high speed cylindrical rotary brushes clean the rollers from below.  The rollers have left and right hand helical grooves which advance the product along the rollers from the hopper to a discharge end while being processed.  The knurl patterns of the rollers preferably have a plurality of longitudinal V-shaped grooves cut into them for about the first 6 to 10 inches of the rollers to damage the roe and liver which are then more readily caught in the nip between the rollers.

Granted: 1992-04-14
Abstract: VEHICLE LOCATING SYSTEM ABSTRACT OF THE DISCLOSURE    A vehicle locating system (VLS)  comprises a large number,  for  example,  several  million,  vehicle-mounted transmitters and several benchmark transmitters;  first, second and third signal  relay stations  and a central processing  station at which the transmitter  locations are determined,  the central station being connected by conventional links to subscriber stations.  One hundred microsecond-long  RF  signals  are  transmitted  by  each transmitter  in  a  non-synchronized,  mutually  random manner.  Each signal comprises a 20 microsecond synchro-nization symbol followed by six,  four bit transmitter identification symbols, each of ten microseconds length.          Following the identification symbols are 10 microsecond message  and  processing  symbols.   The  control  station includes correlation means for correlating the synchro-nization symbols on each relayed signal against stored data  to  identify  the  beginnings  of  the  signals.          Identification symbols of each signal are then decoded by correlation means to establish transmitter identifi-cation,  a combination of  166 possible  identifications being provided.  Signals arriving in the central station are time-tagged upon arrival and the time differences of arrival   (TDOA)   are   used   to   compute   transmitter location.   Benchmark transmitter computed locations are used to calibrate the VLS.  Means may be provided on the vehicle transmitters to enable the rate of transmissions to be varied,  to thereby enable  encoding preselected messages  relating,  for  example,  to  vehicle  motion, vehicle crashes and vehicle intrusion/theft,  responsive to associated sensors.   Alternatively,  or in addition, specific,  prestored messages may be encoded  into the transmitted   signals   manually   or   automatically   in response to sensor input.

Title: Jamming signal scrambling and descrambling systems for catv
Inventor: FARMER JAMES O
IPC: H04N7/16

Abstract: JAMMING SIGNAL SCRAMBLING AND DESCRAMBLING          SYSTEMS FOR CATV                              Abstract Scrambling and descrambling systems utilizing jamming signals provide improved pictures with minimal distortion due to ghosts and artifacts.  The television signal is combined with a jamming signal or signals located preferably in the vestigial sideband (VSB) of the modulated picture carrier and at about a null in the spectrum of the modulation of the picture carrier by the horizontal sync.  The jamming signal or signals also preferably are placed between the harmonic components of the horizontal sync which define the horizontal sync spectrum and at frequencies which comply with governmental regulations respecting frequency locations of strong signals for CATV purposes.  The jamming signals are generated by phase locking to the horizontal sync signals of the television signals or to a submultiple of the horizontal sync frequency.  Artifacts are further reduced by preemphasis of the transmitted television signal in the sideband opposite to that in which the jamming signal or signals are located and spaced by an equal frequency increment from the location of the jamming signal energy.  In order to extract the jamming signal, so as to descramble the television signal for reproduction in the subscriber's television receiver, a network including at least one surface acoustic wave (SAW) resonator device is embedded in an all-pass network which allows essentially lossless transmission of the television signal spectrum, except for the jamming signal energy and enables that energy to be located close to (e.g., approximately 228 KHz) from the picture carrier in the VSB for enhanced security.
