Abstract: The present disclosure provides a trash compactor and methods of compacting trash. In an embodiment of the present disclosure the compactor is configured to automatically actuate an integrated hydraulic unit that is configured to both pivot a multi-sectioned crush plate and also to lower the plate into a base member. Related methods of compacting are also provided.

Abstract: A multipurpose vehicle coolant recycling device is described. The multipurpose vehicle coolant recycling device includes a pump for pumping coolant through said recycling device, a processing tank for receiving used coolant, a fresh coolant tank for receiving fresh coolant, a filter for removing particulates from coolant, a coolant outlet hose constructed for attachment to a cooling system of a motor vehicle, a coolant inlet hose constructed for attachment to a cooling system of a motor vehicle, and a plurality of control valves for directing flow of coolant through the recycling device. The plurality of control valves are adjustable between a first configuration, a second configuration, a third configuration, and a fourth configuration. The first configuration is constructed for directing coolant from the fresh coolant tank through the pump and through the coolant outlet hose, and directing coolant from a cooling system of a motor vehicle through the coolant inlet hose and into the processing tank.

Abstract: An injector for introducing a fluid composition into an air conditioning system is provided. The injector includes a pump including an internal volume having a first opening and a second opening, and a plunger which moves within the internal volume between a first position and a second position. The first opening includes a first valve for selectively allowing the fluid composition to flow from the internal volume as the plunger moves from the first position to the second position. The second opening includes a second valve for selectively allowing the fluid composition to flow into the internal volume as the plunger moves from the second position to the first position. A hose is provided having a first end connected to the first opening, and a second end constructed for attachment to a port on an air conditioning system. A cartridge including a fluid composition is provided fluidly connected to the second opening of the pump.

Abstract: An apparatus for the treatment and recovery of spent vehicle coolant that involves the following steps:a) removing the spent coolant from the engine;b) treating the spent coolant with sodium dimethyldithiocarbamate to cause dissolved metals therein to form insoluble particles;c) treating the spent coolant of step b) with an aqueous basic coagulating agent such as a polyquaternary ammonium compound in its hydroxide form;d) filtering the spent coolant from step c) through a set of filters and then through a bed of carbon particles, to produce a relatively cleaner liquid; ande) adding to the relatively clear liquid a combination of corrosion inhibitors, buffering agents and alkali, whereby the treated coolant can be recycled to the vehicle for effective coolant performance therein.

Abstract: A dual meter mounting plate member carrying an ammeter and a voltmeter, the plate member having therein recesses to receive the voltmeter and the ammeter, the plate member being removably attached to within a battery charging casing, the ammeter being connected to the charging circuit and the voltmeter having terminals across the battery to be charged to indicate the state of charge.

Abstract: A portable battery power source includes a frame with a pair of upwardly angled support members, a battery supporting tray for holding a source battery, a pair of suspension members extending upwardly from the tray for connecting the tray to the pair of support members attached to a wheel-mounted frame. Panels form the frame and also a housing for protecting the source battery from the elements. The power source housing also has a cable compartment for holding a set of cables for connecting the source battery to an electrical load and space for a charging circuit used for recharging the source battery when it is not in use and a control panel at which the device's functions are controlled.
