Abstract: A funnel bucket apparatus is configured to be mountable to typical loader machinery for depositing flowable material at a deposit site. The apparatus includes a bucket and a funnel cover connected by hinges, a discharge chute attachment, a bucket vibrator, and a hydraulic actuator system. An operator controls the actuator system to move the bucket and funnel cover between open and closed positions such that the bucket retains typical loading functions while the apparatus is in the open position. When the bucket is loaded with material, the operator controls the actuator system to move the apparatus into the closed position and positions the apparatus over the deposit site. Material flows through a discharge opening in the funnel cover, through the discharge chute attachment, and down to the deposit site. Efficient and controllable flow rate of material may be facilitated by the bucket vibrator.

Abstract: An electric drill safety device is provided for dynamically braking a drill when there is contact between the drill bit and an electrically conductive material. A first direction voltage is applied to the motor winding to turn the motor forward. When contact is detected between the drill bit and an electrically conductive material, voltage to the windings is discontinued momentarily and thereafter a reverse direction voltage is provided to the motor windings for a predetermined time.

Abstract: An alarm system is provided in which an alarm condition causes a cellular transceiver automatically to transmit a telephone call to an alarm monitoring station by over-the-air transmission of a signal to a cellular site. A computer at the cellular site will cause communication between the cellular transceiver and an alarm company monitoring station. The alarm system includes a digital communicator with an alarm signal line connected to the digital communicator. The digital communicator is coupled to a cellular transceiver having a programmed keyboard, an audio input and an audio output. The digital communicator has an audio output and an interrogation input. The digital communicator's audio output is coupled to the cellular transceiver's audio input. The cellular transceiver's audio output is coupled to the digital communicator's interrogation input. The digital communicator includes a transmit enable output and a receive enable output.
