Abstract: A feed tray assembly for a belt-fed weapon includes a bottom tray portion configured for mounting at a top of the weapon. The feed tray assembly further includes a feed tray cover mounted to the bottom tray portion and configured for lateral sliding opening and closing movement, such as on laterally extending pins riding in corresponding channels of the bottom tray portion. The feed tray cover has (1) a closed position in which it covers the bottom tray portion to retain the belt of ammunition during operation, and (2) an open position laterally displaced from the closed position to enable insertion of the belt of ammunition. Due to this lateral sliding movement of the feed tray cover, a sighting optic may be mounted on the weapon with a forward portion directly above the feed tray assembly without any undesired mechanical interference.

Abstract: A top cooking appliance is provided having a cooktop with a surface heating unit and a thermally-responsive control device that can include a temperature-sensing thermal switch for controlling the operation of the surface heating unit. When the thermal switch senses that the cooking temperature exceeds a first, predetermined upper threshold temperature, the device can cause an interruption in the operation of the surface heating unit. The thermally-responsive control device can then restore the operation of the surface heating unit when the thermal switch senses that the cooking temperature falls below a second predetermined, lower threshold temperature. The thermally-responsive control device for cooktop burners of the present disclosure can be incorporated in both electric and gas-operated top cooking appliances.

Abstract: A fabrication process produces markers for a magnetomechanical electronic article surveillance system. The marker includes a magnetomechanical element comprising one or more resonator strips of magnetostrictive amorphous metal alloy; a housing having a cavity sized and shaped to accommodate the resonator strips for free mechanical vibration therewithin; and a non-deactivatable bias magnet adapted to magnetically bias the magnetomechanical element. The process employs adaptive control of the cut length of the resonator strips, correction of the length being based on deviation of the actual marker resonant frequency from a preselected, target marker frequency. Use of adaptive, feedback control advantageously results in a much tighter distribution of actual resonant frequencies. Also provided is a web-fed press for continuously producing such markers with adaptive control of the resonator strip length.

Abstract: A multi-stage fabrication process produces markers for a magnetomechanical electronic article surveillance system. The marker includes a magnetomechanical element comprising one or more resonator strips of magnetostrictive amorphous metal alloy housing a cavity sized and shaped to accommodate the resonator strips for free mechanical vibration therewithin; and a bias magnet to magnetically bias the magnetomechanical element. A web of cavity stock is independently produced on a separate machine. The web of cavity stock is thereafter integrated with a feed of resonator strip to facilitate production of a magneto-mechanical marker element. The process employs adaptive control of the cut length of the resonator strips, correction of the length being based on the deviation of the actual marker resonant frequency from a preselected, target marker frequency. Use of adaptive, feedback control advantageously results in a much tighter distribution of actual resonant frequencies.
