Abstract: A system for compacting and storing separately recyclable and nonrecyclable waste materials. The system includes two separate storage and compacting units, one of which is designated for the storage of recyclable material and the other designated for the storage of nonrecyclable material. The system further includes a rack structure having a substantially horizontally extending platform and a plurality of support legs extending downwardly from the substantially horizontally extending platform. The support legs and platform form a passageway or channel for receiving at least a portion of one storage and compacting unit. The other storage and compacting unit is mounted on the substantially horizontally extending platform of the rack directly above the first compacting and storage unit.

Abstract: A method of determining the fullness of a compactor having a reciprocating ram and a container includes the steps of setting a target for the number of reciprocations of the ram required to fill the container to a preselected partial fullness. Each reciprocation of the ram is monitored and the total number is summed. The total number of reciprocations is compared to the target number, and the percentage fullness is calculated from those numbers. The percentage fullness is then displayed locally.

Abstract: An electronic control for a motor which eliminates the motor centrifugal switch and more particularly a control for a domestic refuse compactor which permits the user to control the approximate full trash bag weight and obtain more compaction from a split phase induction drive motor. A ferrite core sensor on the main winding of the drive motor samples the lagging phase angle of the motor main winding current during a compaction stroke. A low force cycle is achieved by terminating the stroke as soon as phase samples fall below a threshold defined at the start of each cycle by a locked motor main winding phase sample acquired prior to starting the motor. A medium force cycle terminates the stroke when compaction forces exceed the main winding breakdown torque.

Abstract: A trash compactor particularly designed for aircrafts and having a front compaction chamber and a rear storage chamber in communication with one another. An L-shaped support is provided in the compaction chamber for supporting a container into which trash is to be compacted. The support has a bottom member formed with a pair of grooves and the bottom wall of the compaction chamber, over which stands the support, is provided with a pair of projecting elements snugly fitting into the grooves. The latter as well as the projecting elements have a right angular wedge shape in a plane perpendicular to the upright rear wall of the support with one side of the right angle facing away from the rear wall.

Abstract: An apparatus which collects recyclable refuse in sorted compartments. Through either automatic sensors or through an operator panel, the apparatus determines the contents of the refuse and directs it to the proper compartment or container. In this manner, recyclable material such as aluminum cans, glass bottles, plastics, etc. are easily sorted to encourage the recycling of this material. Further, periodically, the refuse within the compartments are compacted and disinfected to reduce handling requirements and odors.

Abstract: A refuse compactor includes a frame enclosing a compaction ram for compacting waste deposited into a container. A safety chute, having a magnet, is detachably mounted to the frame via pivots and notches. A magnet sensing switch wired into the compactor's control circuit interacts with the magnet on the safety chute to prevent operation of the refuse compactor when the safety chute is misaligned or absent. A ring bolt, collar, spring and washer are mounted within the frame. A plunger on a contact switch wired into the compactor's control circuit touches the washer. The contact switch interacts with the washer on the ring bolt to prevent operation of the refuse compactor when a predetermined amount of weight is placed on the safety chute. Deflection of the spring moves the washer toward the spring, breaking contact between the washer and plunger, opening the contact switch and immediately disabling the compactor.

Abstract: A waste disposal system is disclosed wherein the fullness of a plurality of trash collection units equipped with industrial compactors can be monitored at or by a central processing unit. The invention recognizes that the compaction cycle of an industrial compactor exerts a force against the trash being compacted, which force translates into a strain on components of the compaction assembly. The stress exerted against the compaction assembly when it is compacting trash is determined by an electronic sensing device. This strain measurement correlates to the amount of trash in the receptacle and, accordingly, is utilized to determine whether the receptacle is in fact full and in need of being emptied. The stress measurement is obtained by electronically measuring the strain exerted against a component of the compaction assembly as a result of the trash compacting action.

Abstract: The invention concerns a compactor for wastes, in particular for compressible trash, and includes a compaction plunger with a compaction blade in the lower part of a trash receiving chamber of a compactor housing.

The invention provides a scoop pivotally supported by the compaction plunger and comprising an acute-angle leading edge for slipping underneath the trash which is continuously accumulating in the receiving chamber. During the return stroke of the plunger, the scoop can be tipped upward about its pivot axis so that the trash behind the compaction plunger is moved in front of the compaction blade of the compaction plunger.

Abstract: A trash compactor is provided having at least a hollow compaction chamber rtically disposed on a base and a compacting ram slidaly fitted within the compaction chamber, such that the compacting ram is disposed above the trash to be compacted. The trash to be compacted is first loaded into the compaction chamber between the base and the compacting ram. A downward compaction force is then applied to the compacting ram to compact the trash within the compaction chamber to the required density. The downward compaction force is then maintained while the compaction chamber is removed from around the compacted trash. Finally, the downward compaction force is removed from the compacting ram thereby leaving a compacted trash slug. The trash may be wetted prior to compaction to further enhance the delamination characteristics of the trash slug.

Abstract: A built-in bale ejector for use in a trash compactor comprises an elongated band which is fastened at one end to the floor portion of the compactor cabinet at a front edge thereof and which passes between the floor and a box in which the refuse is to be compacted and then up the inside rear wall of the compactor to a predetermined height. The compactor includes a vertically movable compaction plate which can be driven in reciprocal fashion downward into the box to compress the refuse therein and upward to a "ready" position. When it is desired to eject a filled box, a spring-loaded take-up reel mechanism coupled to the compaction plate can be latched against rotation by a locking mechanism. When so locked, the return stroke of the compaction plate pulls the band tight and thus urges the box filled with the compacted trash to be ejected out through the door opening of the compactor cabinet.

Abstract: Disclosed is a refuse compactor particularly designed for aircrafts, which comprises a compaction chamber having a movable wall panel that extends parallel to one of the side wall of the compaction chamber, and can be moved away from this side wall through a very simple mechanism which is operated either directly by a hand-lever or indirectly through the service door of the compactor cabinet when this service door is closed for refuse compaction into a container. In both cases, the very purpose of this lateral motion of the movable wall panel relative to the adjacent side wall is to release the pressure of the refuse container inside the compaction chamber after completion of the compaction, and thus makes this container easily discardable into a storage chamber if any, or out of the compactor. The operation of the movable wall panel is exclusively mechanical and is therefore very simple and reliable.
