The invention relates to the use of a cyclone separator for separating keratin particles originating from poultry out of a gas, in particular air. The separated particles comprise down particles. The invention furthermore relates to a climate chamber for hatching eggs and/or keeping poultry. Said climate chamber comprises a substantially closed compartment having two opposite side walls provided with one or more passages; as well as a substantially closed duct which extends outside the compartment and connects one of said side walls to the other of said side walls so as to form a substantially closed circuit together with the compartment. Said climate chamber furthermore comprises a cyclone separator, the inlet of which ends in the substantially closed duct and the outlet of which ends outside the closed duct for discharging into the environment.

Heat exchangers extract heat from an air stream and deliver the heat to another airstream. The heat exchangers are modified with a filtration system to allow the heat exchanger to effectively run within the poultry house environment. The poultry house is retrofitted with at least four flat-plate cross-flow heat exchangers. The heat exchangers operate to meet at least the minimum ventilation rates for the young birds. As birds grow, heat exchangers operate in conjunction with building exhaust fans for ventilation needs. Multiple heat exchangers are located throughout the house to provide appropriate ventilation.

A system for automatically detecting the presence of a cage or tray for containing laboratory animals in a specific position of a facility shelf and a method for managing the data relating to the cage, implemented by the system, particularly advantageous for the laboratory technician. In particular, the system is composed of a shelf comprising a plurality of devices designed to detect the position in the facility and the ID of a cage, a central control unit designed to process, through software, the information received in order to offer the operator the possibility of tracking and managing, by means of a database, the whole facility. Numerous other functions of the system are included, such as the function designed to detect and notify, visually or through the software, the correct positioning of a cage in the shelf.

A smart pet-crate is disclosed. The smart pet-crate provides a den-like habitat for an animal and is configured with electronics that include sensors to detect aspects of the animal's environment and environmental conditioners to adjust the environment within the pet crate in response to the detected aspects. The conditioned environment within the pet crate will provide comfort to the animal, which may help to reduce the animal's fear/anxiety. The smart pet-crate may be communicatively coupled to a body sensor worn by the animal and a computing device used by a human to form a pet care system, allowing for remote control of the pet crate and interaction with the animal. For the particular embodiment of a smart music playing pet crate, a method for selecting songs from a playlist based on sensing and computing the animal's preferences is also disclosed.

An environment-friendly piggery comprises at least one circular or polyhedral piggery building. Each polyhedron has five sides or more, and a ventilation shaft is provided in the middle of each floor of each piggery building; each floor tilts from high to low towards the ventilation shaft from the outer edge; the top of each piggery building is provided with a exhaust gas collecting and treatment device communicating with the ventilation shaft; and the bottom of the buildings are provided with pig excreta collecting devices corresponding to the opening of the ventilation shaft. The piggery occupies a small area, has strong wind and snow resistant functions, and is sturdy and durable. The culturing process is pollution-free, and piglets, pigs, and sows can be accommodated appropriately.

A base carrying a left-side panel and a right-side panel. A top panel is disposed on and extends between said side panels, wherein said base, said side panels and top panel define a pet receiving area. A blower unit disposed at a rear side of said pet receiving area drawing air in a direction from a front side to said rear side of the housing across the pet receiving area. An airflow control covering disposed on at least one of said left-side panel and said right-side panel providing a reduced airflow entering said pet receiving area through the side panel relative to a front side of the housing, wherein a negative air pressure is established within the housing while providing a primary airflow direction from said front side to said rear side of the housing to container pet hair, dander and debris within said housing.

Novel polyanionic polymers including families of repeat units, such as maleic, itaconic, and sulfonate repeat units. The polymers are at least tetrapolymers and may be in the acid form or as partial or complete salts. The polymers may be synthesized using free radical initiators in the presence of vanadium compounds. The polymers have a variety of uses, particularly in agricultural contexts.

A fan for use in agriculture includes a housing, a motor, a propeller, a damper, and a controller. The damper is connected to the housing and is movable between open positions and a fully closed position. The controller controls the motor to rotate in a first rotational direction to cause the propeller to generate airflow in a first airflow direction through the housing from an inlet to an outlet and, upon receiving an instruction to shut down, controls the motor to rotate in a second rotational direction, opposite to the first rotational direction, to cause the propeller to generate airflow in a second airflow direction, opposite to the first airflow direction, through the housing from the outlet to the inlet, before ceasing rotation.

The invention comprises systems and methods for controlling environmental conditions within and/or around an animal enclosure. The systems and methods preferably comprise a climate control system and infrared sensors in a poultry house having a first climate and housing poultry having one or more measurable parameters such a temperature. The infrared sensors detect infrared light information emitted by a head and/or vent of poultry in the house. The climate control system processes the information to calculate an internal temperature of poultry and activates one or more climate conditioning devices in the house to change the first climate to a second climate determined by the detected information and/or calculated internal temperatures of the poultry. The systems and methods may be deployed in houses comprising thousands of poultry and one or more climate zones. The systems and methods may make one or more climate changes based on one or more different parameters.

The invention relates to an apparatus for simulating one or more eco habitat conditions. The apparatus includes at least one eco capsule unit and an air inlet chamber for receiving air. The eco capsule unit includes a pressurized water driven turbine, a low-pressure vacuum chamber, a pressurized humid air chamber, where the pressurized water driven turbine is configured to receive pressurized water to propel the pressurized water driven turbine, for generating a highly humidified air-water mixture and a pressurized humid air-water vapor by creating turbulence. The vacuum chamber is configured to enable a wind chill simulation and to remove heat from water for generating a water with reduced temperature by controlling the rate of evaporation of water. The pressurized humid air chamber is configured to capture the turbulence created water-pollutant mixture, highly humidified air-water mixture and the pressurized humid air-water vapor, to be expelled or recycled via an air blower or a humid air exhaust, for removing pollutants from the air to generate purified air with a desirable temperature.
