A waste screen for roof drainage outlet located substantially in the plane of the roof consists of an outlet opening in the roof and a plate covering the opening having a circumference and vertical distance from the roof plane so that at least at dimensioning flow amount air is prevented from being sucked in beneath the plate edge and the gap between the plate and roof plane constitutes the outlet port. The water on its passage from the pitch to the outlet opening always passes through the outle...

A waste bag for collecting solid waste excretions of a horse includes a bottom cup-like portion and a back portion extending upwardly from the rearward side of the bottom portion. Edges of the back portion are resiliently reinforced so that the back portion conforms to the horse's hips and permits excreted waste to be directed into the bottom portion. A zipper in the bottom portion permits the bag to be selectively emptied without removing the bag from the horse. Drainage holes in the bottom por...

The present invention relates to a method of destroying waste to form a leach-proof slag and a gas containing only H.sub.2 and CO as combustible constituents. The method comprises the steps of: (a) supplying waste material at the top of a shaft furnace while simultaneously supplying energy in the form of hot oxidizing gas at the bottom of the shaft furnace, (b) discharging liquid slag from the bottom of the furnace shaft and withdrawing the gas generated, at the top of the furnace shaft, and (c)...

A waste container is composed of synthetic resin material and is provided at the front wall with a recess bridged by a grip formed by front and rear portions. The rear wall portion has extensions defining the small sides of the grip space and merging with the back wall portion of the recess or with a wall parallel thereto and connected with the back wall portion.

A container with a front opening and a top opening, and a top wall preferably hinged to the container to cover the top opening. A hinged front wall covers the front opening and has a curved guide rail extending therefrom which is slidingly received in a curved guide channel formed in the left or right wall, with the rail having a knob for manually pivoting the front wall. A cross-bar assembly preferably comprises two parallel top rods with rollers, two parallel bottom rods with rollers, and two ...

An improved waste receptacle and method for disposing of waste is disclosed. The receptacle includes a container portion configured to receive a liner therein. The container includes a pair of liner retainer elements secured to the outside surface on opposite sides of the container. In one embodiment, the liner retaining element includes a pair of spaced flanges protruding from the wall of the container. The liner retaining elements are configured to receive a portion of the liner disposed in th...

A process for atomically converting gaseous waste materials into nonhazardous forms and a medium BTU gas is described. The reactor includes molten layers of iron and reactive slag in an upwardly flowing reactor operated under oxygen lean conditions.

This invention relates to a process for thermally cracking waste polymer(s) comprising chlorinated polymers in a reactor in the presence of a fluidizing gas and a fluidized bed of solid, particulate fluidizable material at a temperature from 350.degree.-600.degree. C. to cracked products comprising a mixed vapor of lower hydrocarbons which have a chlorine content of less than 50 ppm. In the process, the cracked products emerging from the fluidized bed are passed through one or more guard beds co...

A waste disintegrator for comminuting solid particles in a fluid passing therethrough having a transverse wall in its housing, the transverse wall having a central opening through which the fluid is channeled and a comminuting means is mounted in that opening. A fluid bypass is formed in the transverse wall in a peripheral area thereof and covering this opening is a flapper valve that is pivotally secured to the downstream side of the transverse wall. The flapper valve has one of its ends fixedl...

Waste materials to be disposed of are fed into a feed hopper, the outlet of which is directed into a rotary vane feeder to automatically control the feed rate and act as an airlock. Shredded waste material is stacked in a pyrolyzing chamber or column through which hot gases, initially containing no oxygen pass upwardly, driving off volatile material. A condenser reclaims the condensable materials, and the non-condensable gases are recirculated through the combustor and pyrolyzing chamber carboni...
