Detonable devices such as charged air bag inflators are fed to a shred tower at a controlled feed rate via a feed valve. Water spray and/or water baths in the shred tower prevent sparking and begin to solubilize chemicals while the inflators are fed to primary and optional secondary shredders respectively performing course and fine shreds. A sump receives the shredded material which continues solubilize and separate chemicals from metal. A conveyor lifts solids from the sump. Dewatered solids are fed to a receiving box for metal scrap recycling.

A mechanical bin-full device for a paper shredder with a bin, having a curved, perforated T-blade sensor on a cylindrical body partially covered with a metal sheet. The T-blade is pendent into the bin. Metal contacts are placed on the paper shredder near the metal sheet, forming a switch, which is coupled to a motor control circuit for the shredder motor. The T-blade is pushed by paper shreddant and rotates the cylinder body as paper shreddant fills the bin. When the bin becomes full, the T-blade is positioned so that the metal contacts touch the metal sheet, closing the control circuit switch, and causing the motor to cease operating. The control circuit can include a microcontroller coupled to the motor, or a transistor-based driver coupled to a motor relay.

A control unit for a food waste disposer has a controller that determines operational status of the food waste disposer based on motor loading of an induction motor of the food waste disposer.

The present invention relates to a container grinding system having a box equipped with a closing device coupled to a first safety device, the box having a container introduction opening arranged in a top part of the box and capable of being closed by the closing device, the grinding system having a grinder having at least one grinding shaft for shredding chipped containers, a filtering basket recovering the ground material from the grinding of containers, and a set of rinse nozzles, the grinding system being configured so that following the introduction of a container into the box for grinding the same, the first safety device inhibits the operation of the grinder as long as the closing device does not ensure closing of the box.

A system includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the system can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.
