Abstract: A cap having two chambers provides a means for and method of decomposing or neutralizing a hazardous chemical residue in a container after it has been emptied at the point of consumption. One of the chambers is a screw cap which normally closes and seals the container prior to the consumption of the hazardous chemical. The other chamber contains a measured amount of a second chemical which decomposes or neutralizes the residue of the hazardous chemical. The other chamber may be sealed off by a rupturable membrane, a screw cap, a friction held stopper, or a tear-off top, any of which may be ruptured or removed at the time when the residue is to be decomposed or neutralized. In the preferred embodiment, a screw cap is removed from the second chamber and the cap is inverted and screwed onto the container rupturing the membrane in the process, thereby releasing the second chemical into the container.

Abstract: An apparatus for separating fine particulates from a particle flow having a generally vertically disposed column with a particle flow channel. A particle flow inlet and outlet are located at opposite ends of the column in which an airstream is produced. Alternatively arranged downwardly slopping baffles are exposed on opposite sides of the channel for receiving and distributing the particle flow to the airstream. Each successive baffle is longitudinally spaced from the previous baffle. A mechanism is provided adjacent the bottom of each baffle for fanning out the particle flow and for removing the fine particulates from the fanned out particle flow into the airstream.

Abstract: A package or bed of litter for small animals, having at least two horizontally disposed layers of particulate, liquid absorbent material, the upper layer of which is of relatively coarse particles and contains an odor suppressant therein. The lower layer may have odor suppressant in an amount substantially less than in the upper layer, though normally the lower layer would not contain any substantial amount of odor suppressant material. The litter is normally packaged in an elongated container, with the relatively coarse particulate material on top and the relatively fine particulate material on the bottom. When the litter is to be used, the bottom of the container is opened to permit the discharge of the litter from the container into a box, with the relatively fine material on the bottom and the relatively coarse material containing the odor suppressant on top.

Abstract: A bulk storage building structure for storing grain, dried clay and other granular products in which the normally encountered lateral pressure exerted on the walls of the structure is minimized by the spaced, slatted configuration of the walls which accommodates the angle of repose of the stored material. This configuration effectively increases the total available surface area of the structure such that the structure may be made as large as is necessary of practicable without the expensive wall reinforcements required for conventional storage structures.

Abstract: A cat box filler system in which two layers of litter are provided in the container in which the material is shipped and sold. The container is provided with a place to be opened when the filler material is to be discharged in a cat box. The layer in the bottom or farthest from the opening in the container contains a substantial amount of odor suppressant and the other layer contains little or no odor suppressant. When the container is to be used the end of the container farthest from the layer with the odor suppressant is opened and the container is held with a hole at the bottom so that the first layer with little or no odor suppressant flows into the cat box, and the layer with the odor suppressant flows over the first layer, forming the top layer of the material in the cat box. The invention also includes the method involving the steps of emptying the container into the cat box to form two layers therein.

Abstract: An apparatus for testing small animal litter in which a plurality of compartments are employed for living quarters for the small animals, such as cats, and for a container with litter to be tested, and these animal compartments are connected by conduits to a compartment for a tester to use to sniff the odor from any one of the animal compartments. Valves are preferably provided in the conduits, and controls for the valves extend externally of the apparatus so the valves can be operated separately by an operator without interfering with individual tests. Fans in or near the top of the compartments are used to circulate air through the animal compartments while the animals are living normally therein, and a fan is provided in the tester's compartment for drawing the air from any selected one of the animal compartments into and through the tester's compartment.

Abstract: An animal measuring apparatus for measuring various parts of the anatomy of an animal, in which a wall is provided with lines representing graduations of a scale useful in measuring the animal. The lines of the scale extend the width of the wall, permitting measurement of various parts of the animal without moving the animal or scale. The wall can be of two panels suspended on a track for lateral movement in a vertical position, and the animal can be positioned between the panels.

Abstract: A flavoring dispenser in which upper and lower layers are sealed to each other along their edges to form a pouch-like structure. A flavoring substance is contained in the structure and a plurality of apertures are disposed in the lower layer. The dispenser is placed on meat or other food being cooked, and the flavoring substance seeps from the dispenser onto the food. The flavoring is a liquid or other substance which liquifies during the cooking of the food. The steam and heat from the food and/or from the flavoring substance cause the pouch to swell, thereby forcing the flavoring substance through the apertures. A plurality of dispensers may be packaged in a sheet-like arrangement with perforations between the individual dispensers permitting each to be detached from the sheet.

Abstract: A container and dispenser for dry particulated chemicals, such as agricultural pesticides, in which the container has two walls forming a corner at one end of the container, and an opening in the corner for discharging the chemical in the container therefrom. A removable closure seals the opening while the container is being shipped and stored and a retractable closure is disposed within the container for closing the opening when the closure has been removed in preparation for discharging the chemical into the dispensers. The dispenser is so constructed and designed that it holds the container in the position where the opening is at the bottom for discharging the contents from the container, and a projection is provided on the dispenser for retracting the closure disposed in the container when the container is placed in the dispenser. A spring may be provided for urging the closure in the container to its closed position so that the container is automatically closed when it is removed from the dispenser.
