  • Patent number: 6058860
    Abstract: The seeder apparatus includes a first hopper for dispensing seeds onto a conveyor mechanism to be moved thereby to an entry nip between a rotary brush and the conveyor mechanism for propelling the seed downwardly at the discharge end of the frame on which the hopper is mounted. A shield assembly is mounted to the frame discharge end portion to minimize the effects of wind on the trajectory of seed or other material being propelled to the ground by a brush and conveyor mechanism. In one embodiment, a metering gate extends vertically in its closed position relative to the conveyor mechanism, the metering gate controlling the rate of dispensation of seed being moved to the entry nip.

  • Patent number: 6047105
    Abstract: An off-peak electric heat storage and discharge device includes variably sized thermal media material contained in a rock box. A calrod-type heating element is located in and in direct thermal contact with the thermal media material. Air flow can move from a fan upwardly through a duct, through slots formed in the duct into the rock box, and through the thermal media material. Air flow can also move from the fan through a bypass duct. Heated air and cold air can be mixed in proper proportions by a rotatable damper movable between a position closing off all cold, bypass air and a position closing off all heated air. The damper falling to shut off the flow of heated air in the event of an actuator failure. All electric controls and the fan are contained in a vertical control chamber designed to convectively convey heat during static conditions. The thermostat for the device is located at the lowest point possible in the vertical control chamber and below a point which could be affected by convective air flow.

  • Patent number: 6042656
    Abstract: An apparatus (200) is provided in a floor scrubber (10) for automatically shutting off the motor (60) which rotates an agitator (64) and the motor (96) of a vacuum assembly under various operating conditions of the floor scrubber (10). The current to the motors (60, 96) is detected by devices (204, 206) and monitored by a control circuit (202) controlling devices (208, 210 which interrupt operation of the motors (60, 96). In the preferred form, operation of the agitator (64) is interrupted when the current to the brush motor (60) is less than or equal to a threshold level indicating that the agitator (64) has been raised from the floor surface as the current to the brush motor (60) would be above the threshold level when the agitator (64) engages the floor surface. Operation of the vacuum assembly is interrupted when the current to the vacuum motor (96) drops to a fixed percentage over a period of time from normal operating levels indicating the path of the air in the vacuum assembly has been blocked.

  • Patent number: 6041550
    Abstract: An elongated cover is removably mounted to a channel guide of a jamb liner for a window unit that is mounted for movement between opened and closed positions. A balance spring in the channel guide has one portion attached to the top end of the jamb liner and an opposite end mounted to a balance shoe which frictionally engages the channel guide. The shoe is mounted to the lower end portion of the window unit. The cover includes a longitudinally elongated main body extendable within the channel guide, a resilient tube mounted to one transverse edge of the main body to abut against a channel guide side wall and rear wall to resiliently urge the main body away therefrom and a mounting joined to the main body transversely opposite the tube for forming a channel to engage a flange of the channel guide. The resilient action of the tube releaseably couples the cover to the channel guide to conceal the spring which extends above the window unit when the unit is closed or partially opened.
