Title: Meat trim sorting
Inventor: BROWN GARY
IPC: B07C5/36
Filed: 1994-10-19
Granted: 1998-09-22
Abstract: A sorting system is disclosed for reclaiming lean meat from high-fat meat trimmings. The sorting system includes a meat dicing machine which receives laterally extending whole meat trimmings and which dices such meat trimmings without grinding or extruding, and without disturbing the lateral distribution of the meat. This results in a lateral distribution of meat trimmings, without requiring vibratory distribution which is disfavored in meat processing plants. A wide-belt inspection conveyor is positioned at the downstream end of the meat dicing machine to receive the laterally distributed meat dices. The wide-belt inspection conveyor operates at a greater linear speed than does the meat dicingmachine to longitudinally space the meat dices from each other. An optical inspection and sorting station is positioned at the downstream end of the wide-belt inspection conveyor to differentiate relatively lean meat dices from relatively fatty meat dices and to separate such meat dices from each other.

Title: Synchronization circuit for visual/audio alarms
Inventor: KOSICH JOSEPH
IPC: H05B41/34
Filed: 1994-09-14
Granted: 2003-08-19
Abstract: A strobe alarm system which includes multiple normally self-timed strobe circuits connected in a common loop to a fire alarm control panel, and a sync control circuit, which may be incorporated in the fire alarm control panel, for causing the strobes to flash in synchronism at a predetermined rate which will insure that a person viewing the multiple strobes would not see dash rates higher than the predetermined synchronized rate, which is preferably less than five flashes per second. The sync control circuit does not interfere with the supervision functions of the alarm system, and when an alarm condition is present it supplies power to the strobe circuits which it then interrupts once every flash cycle to cause a sync trigger circuit in each strobe to fire its flashtube, and to reset the internal timer of each strobe to ready it for arrival of the next sync signal. Each strobe circuit in the loop includes a resettable timer for recycling its own flash unit in a non-synchronous fail-safe mode in case the sync signal should fail to appear within a finite period following the last previous flash. That is, normally the strobes are all fired at the same time in response to sync signals applied to their sync trigger circuits, but in the event the sync signal is lacking the strobes will continue to flash, each at a rate determined by its internal timer.

Abstract: A vaccine for the immunocontraception of mammals is described. The vaccine consists of zona pellucida antigens and an adjuvant encapsulated in a liposome delivery system. The liposome delivery system allows for the slow release of antigen resulting in a prolonged immune response. In particular, after a single injection of the vaccine, levels of anti-zona pellucida antibodies were detected for up to 22 months. Thus, the vaccine according to the present invention is effective after a single dose and is therefore very useful in immunocontraceptive protocols.

Abstract: A control relay circuit and method for controlling a relay having a coil, for use, in particular, in operation of a light fixture circuit having an HID lamp. The relay control circuit has an input for receiving a control voltage signal and a voltage storage element connected across the input. The voltage storage element develops a voltage level as a function of time in response to the control voltage signal. A thyristor circuit, a switching element and the coil of the relay form a series circuit that is connected in parallel to voltage storage element. A switch controller is connected in parallel to the voltage storage element and is also connected to the switching element. In response to the control voltage being received at said input, the switch controller activates the switching element to a conductive state at a first voltage level across the voltage storage element and the thyristor changes from a non-conductive state to a conductive state at a second voltage level across the voltage storage element, the first voltage level being less than the second voltage level. In response to the control voltage being removed from the input, the switch controller activates the switching element to a non-conductive state at a third voltage level across the voltage storage element thereby changing the thyristor from the conductive state to the non-conductive state thereof, the third voltage level being less than the second voltage level. The relay is energized at the second voltage level and is deenergized at the third voltage level.

Abstract: An autonomous bomb damage assessment system (10) that is piggybacked to a bomb (11) to provide imagery of a bombed area immediately after bomb delivery. The bomb damage assessment system (10) comprises a housing (20) that is releasably secured to the bomb (11). An imaging system (13) is disposed at one end of the housing (20) and a folded inflatable balloon (18) is disposed at the other end of the housing (20). An inflation device (17) is provided for inflating the balloon (18) with a lighter-than-air gas such as helium. A proximity fuze (14) is used to sense the location of the ground, for causing the system (10) to be ejected awayfrom the bomb (11) shortly before bomb impact, and for causing the inflation device to inflate the balloon (18). A data link (16) is disposed in the housing (20) for transmitting images derived from the imaging system (13) to a remote location. The present invention provides imagery of a bombed area immediately after bomb delivery. The lighter than air characteristic of the system (10) allows a dwell time over the bombed area so debris and dust can settle. Fine resolution and short range provide detailed images. Television or infrared cameras may be used as theimaging system (13) to permit for day or night missions. The data link (16) allows images to be recorded in an aircraft sent via satellite to a recording center. The images may then be flown back to a base or relayed from the aircraft to the baseusing another data link. Bomb damage assessment may be performed at the base within minutes after an attack.

Granted: 2001-10-23
Abstract: A sealed-combustion chamber fireplace includes a combustion air to fuel adjustment device comprising an primary air-fuel mixing body having a fuel source inlet at one end and at least one combustion air inlet port disposed through a wall portion of the body. The air- fuel mixture body may be configured in the form of an air-fuel venturi, burner tube and the like to effect mixing together of the air and fuel to form a combustible air-fuel mixture. An air inlet port cover is movably disposed adjacent the air-fuel mixing body and forms an adjustable air combustion aperture by placement of the cover adjacent the air inlet port. Movement of the cover about the body effects opening or closing of the aperture, thereby effecting adjustment of the primary air to fuel ratio of the air-fuel mixture combusted in the combustion chamber. A cover arm is attached to the cover and an actuator arm is movably attached to the cover arm to facilitate adjustment of the aperture, thereby, permitting adjustment of the flame appearance during operation of the fireplace from a position outside of the fireplace.

Granted: 1999-12-14
Abstract: La présente invention concerne un dispositif de transport des signaux à grande vitesse (10) assurant la transmission de données par un canal équilibré (14). Le canal équilibré (14) véhicule des signaux différentiels provenant de la sortie d'un émetteur différentiel (12). Un égaliseur (18) corrige la distorsion se produisant dans le canal équilibré pour réduire la gigue de rythme du signal. Le signal est appliqué sur l'entrée d'un récepteur différentiel (20) qui exploite le seuil précis de quantification inhérent à toutes données différentielles pour convertir avec précision le signal en données numériques. Le récepteur différentiel (20) remet les données numériques par rapport à l'horloge locale à l'aide d'une référence de fréquence connue, conjointement avec une détection de transition numérique. Le signal véhiculé par le canal équilibré (14) n'étant soumis à aucune limitation du rapport cyclique, ni l'émetteur différentiel (12) ni le récepteur différentiel (20) n'ont à coder le signal. Pour ce qui concerne le récepteur différentiel (20), l'ampleur du rapport signal-densité de bruit permet une quantification précise, l'égaliseur réduisant ainsi les gigues de rythme au maximum et supprimant la nécessité d'employer des circuits de resynchronisation analogique.
