Abstract: A method for establishing a hydrological cycle in a closed ecological system is disclosed. The hydrological cycle results in the establishment of a variety of different micro-environments which simulate micro-environments of Earth. The hydrological cycle further results in the establishment of a symbiotic interrelation of organisms in that are established within the different micro-environments, where the wastes generated by organisms of one micro-environment are removed by organisms of a second environment and are used as nutrients. This biological purification of the water maintains the purity and functionality of the water for continual use within the closed ecological system.

Abstract: Overhead wall mounted cat platform system with multiple access wherein access is provided by a carpeted pole or by one or more inclined suspension bridges. Each bridge comprises a plurality of spaced platforms. The platforms are interconnected by ropes and suspended from support ropes by connector ropes extending between the support ropes and the step ropes.

Abstract: An animal squeezer cage converter for a cage is provided and consists of an inner push rack which fits into and can slide towards and away from rear wall of the cage and an outer cage door frame which hinges and locks into place on the cage. The push rack can be releasably attached to rear of the cage door frame while there is a mechanism for adjustably locking and releasing the push rack between the cage door frame and the rear wall of the cage to restrain an animal therein.

Abstract: A mess-free bird feeder for a bird cage having enclosing walls and roof, and a generally open bottom. Seeds, seed husks and the like are intercepted and directed downwardly to the droppings tray of the cage, avoiding the scattering of such materials outside of the cage.

Abstract: An apparatus for aerating fish ponds utilizes a cylindrical brush mounted for rotary motion below the top of a dam or headwall. Water passing over the dam and falling into a fish pond below the dam falls onto and over the cylindrical brush causing the brush to rotate. The rotating brush breaks up the falling water into droplets as the water passes through the brush bristles. Below the rotating brush, the water droplets fall through an air-water mixing zone where atmospheric oxygen is dissolved by the water droplets thus increasing the dissolved oxygen concentration of the water.

Abstract: A vivarium comprising at least one terrarium completely submerged in the water in an aquarium. The terrarium and the aquarium shares a common bottom, but are not in fluid communication. The terrarium is accessible through an access opening on the bottom of the terrarium. There can be transparent passageways linking various portions of the terrarium and extending through the aquarium, for travel by animals kept in the terrarium. There can also be transparent passageways linking various portions of the aquarium and extending through the terrarium, for travel by the marine organisms kept in the aquarium.

Abstract: A pulsation selector for milking machines is adjustable to enable alternate milking between the front and rear or between the right and left teats of the animal.

Abstract: This invention relates to an animal litter to which has been applied on odor-inhibiting amount of a guanidine salt.

Abstract: A fan assembly (10) for an egg incubator enclosure (1) or for a hatching enclosure, in which a centrifugal fan establishes a pressure reduction and thereby sets up a flow of air through egg storage boxes disposed in the vicinity of the fan, wherein the centrifugal fan comprises two turbines (20) mounted on a horizontal axis and disposed substantially in the middle of the enclosure, with the boxes (2) placed on either side of the turbines, and with each turbine being constituted by a ring (21) which is hollow in the center and provided with blades (22) around its periphery. Advantageously, fresh air and recycled air are air-conditioned by being humidified (42), and heated (30) or cooled (41, 51) as required, in the central zone (11) lying between the two spaced-apart central rings of the two turbines, prior to coming into contact with the eggs to be incubated.

Abstract: An apparatus primarily for use with dogs which prevents the animal from jumping or being thrown from the open bed of a pickup truck. The apparatus uses a main cable removably attached at one end to a hinge mounted to the front panel of the truck bed. The opposite end of the main cable is removably attached to a second hinge mounted to the truck bed floor adjacent the tailgate. Attached generally centrally on the main cable are two spaced cable clamps. The position of the two cable clamps is adjustable on the main cable. A short leash is removably and slidably attached to the main cable between the two cable clamps. The opposite end of the leash removably attaches to the collar of an animal. The frontward to rearward movement of the animal in the truck bed may be controlled by locating the cable clamps on the main cable to prohibit the leash from sliding excessively close to one end of the other of the truck bed.

Abstract: A process for sanitizing and increasing the hatchability of hatchery eggs by exposing the eggs to a solution of hydrogen peroxide during one or more stages of the hatchery process prior to hatching. The process unexpectedly results in a significant increase in the hatchability of the eggs treated.

Abstract: This invention is concerned with a chamberpot for domestic pets such as cats. The chamberpot allows sand to be removed therefrom with ease, and cleaning work to be done in a simple manner. The chamberpot is constructed to receive a scoop to enable pet keepers to dispose of their pets' excrement without dirtying their hands.

Abstract: Trapping apparatus for livestock comprising a first barrier partially defining an enclosed area and having an entrance for admitting livestock into the enclosed area, a rotatable gate extending between the open ends of the first barrer and rotatable about a vertical support to sweep the enclosed area, a second barrier extending between one end of the first barrier and the gate support, and a detector for detecting livestock located within the enclosed area and arranged to initiate rotation of the gate whereby livestock located in the enclosed area are forced through an opening between the gate support and the other end of the first barrier.
