A collapsible pet crate is provided that includes a top; a bottom base; and a plurality of walls including a first wall pair. The first wall pair includes a first wall pivotably connected to the bottom base for pivoting about a first horizontal axis and a second wall pivotably connected to the first wall for pivoting about a first vertical axis. The collapsible pet crate being configured for arrangement in a crating orientation in which the top is removably connected to at least one of the walls and a collapsed orientation in which the top is removably connected to the bottom base. A method of providing a collapsible pet crate is also provided.

An animal lift consisting of a lift mechanism, a vertical mast housing at least a portion of the lift mechanism, a horizontal shaft rotatably coupled to the lift mechanism about a longitudinal axis of rotation of the shaft, and a cradle coupled to the shaft, the cradle constructed of a horizontal support member having a surface for engaging the sternum or underbelly of an animal along the animal's longitudinal axis from head to tail and a pair of vertical side walls.

A ventilator unit has a ventilator housing and at least one ventilator accommodated in the ventilator housing. A first outlet guide apparatus is associated with the ventilator and is arranged in the ventilator housing, wherein the first outlet guide apparatus has first outlet guide vanes distributed circumferentially. A second outlet guide apparatus is correlated with the first outlet guide apparatus and arranged in a flow path of an air stream sucked in by the ventilator. The second outlet guide apparatus is connected to a protective screen. The second outlet guide apparatus has second outlet guide vanes. The second outlet guide apparatus increases the throw of the ventilator unit.

The invention encompasses devices, methods and systems for restraining, transporting and manipulating an animal, including lifting, rotating and tilting the animal.

An animal comfort accessory for use with an animal enclosure includes a cover configured to fit over the animal's enclosure to decrease noise and light for the animal in the enclosure. A scent blower moves air past a scent collector and delivers a soothing sent to the animal inside the enclosure. The scent blower and cover are contained in a pouch for convenient storage and travel. Additional accessories such as a speaker, camera, and video display may also be stored in the pouch and used with the animal to provide a comforting space for the animal.

The present invention involves a fabrication of a trapezoidal-duct assisting poultry ammonia gas, hydrogen sulfide gas, and dust removal system to be used for removing of the poultry ammonia gas, hydrogen sulfide gas, and dust from the exhausted air stream emitting from the poultry houses and litter storages, comprising a poultry ammonia gas removal tube-screen-scrubber device invented in the present invention, hydrogen sulfide gas adsorber, dust filter, air-speed-acceleration trapezoidal-duct, ventilation-fan, and auxiliary system. The poultry ammonia gas removal tube-screen-scrubber equipped in the poultry ammonia gas removal tube-screen-scrubber device is invented in the present invention using the tube-screen-fill pack patented by the present inventor for use in the water cooling tower. The air-speed-acceleration controller trapezoidal-duct is applied for connecting of the large air outlet cross section of the tube-screen-scrubber device and the small air inlet cross section of the ventilation fan.

A structure formed with a frame structure and a sheet of material configured to reduce sound is wrapped around or otherwise surrounds the frame structure to form a hammock, basket, meditation pod, animal bed, snore reduction unit, wearable enclosure or other small structure, with an inner, sound limited or reduced volume. The sheet of material includes a base layer and at least one layer of sound-absorbing material, at least one layer of sound barrier material, or both, provided on or integral with the base layer. The sound limited or reduced volume includes an opening that may be closed or partially closed with a flap, canopy or hood. The flap, canopy or hood is preferably made of the same material at the sheet of material surrounding the frame.
