A circular grazing system for poultry and/or livestock. The circular grazing system including a center pivot structure installed at a field. The center pivot structure may have a center pivot axis. The field may be a poultry and/or livestock grazing field. The circular grazing system for poultry and/or livestock may include an enclosure for containing poultry and/or livestock. The enclosure may extend generally radially from the center pivot structure to a circumference of the field. The enclosure may be rotably coupled to the center pivot structure such that the enclosure rotates around the center pivot axis.

Animal drinking troughs have pressure reducers for reducing the higher pressure of the liquid supply to a low liquid pressure for supplying the animal drinking troughs. For various reasons, it is desired to change the reduced pressure. This takes place by adjustment of the pressure reducers. It is known to undertake such an adjustment with compressed air. This requires a separate compressed air source and a corresponding pipe system. The invention makes provision to adjust the pressure reducer hydraulically by means of the higher pressure of the liquid of the liquid supply. The energy required for adjusting the pressure reducers thereby provides the liquid pressure of the liquid supply. As a result, the pressure reducers according to the invention operate autonomously. A separate energy source for adjusting the pressure reducers is not required.

A pressure regulator for controlling flow of a fluid therethrough is provided. An upper housing member and a primary diaphragm define an upper chamber and a lower housing member and the primary diaphragm define a lower chamber. The pressure regulator further includes: a valve assembly provided within the upper chamber for controlling the flow of the fluid from an inlet body into the upper chamber; a secondary diaphragm provided within the lower chamber and defining a secondary diaphragm driving chamber; and a passageway connecting the inlet body and the secondary diaphragm driving chamber. During operation, the secondary diaphragm driving chamber is filled with the fluid at the inlet pressure, thereby subjecting the secondary diaphragm to the inlet pressure and generating the force for actuating the valve's disengagement from the inlet body. The pressure regulator functions to maintain the outlet pressure at a value that is a predetermined fraction of the inlet pressure.

A freeze-resistant watering nipple assembly comprising a watering nipple valve, a heat pipe, a sleeve in tight thermal contact with the nipple, a water-tight connection to a liquid containing container or supply pipe, and an outer shield enclosing an insulating space and/or insulation material is described, which thermally couples a watering nipple to a container or supply pipe via a sufficiently good thermal conduction path so that the nipple can be maintained at a temperature that is near the temperature of the liquid in the container or supply pipe. Further, the use of one or more freeze-resistant watering nipple assemblies with a thermally insulated container is described so that the unit comprising the nipple assembly or assemblies and the insulated container provides drinking water to animals, and in particular, birds in sub-freezing and in hot weather.

A smart apparatus system includes one or more food and liquid smart tableware apparatuses that each have a processor, memory, and a weight sensor. The smart apparatuses communicate with a cloud server and one or more caretaker computing devices. The caretakers can input physical information for the user including weight. The smart apparatus system can determine the healthy weight range for the user and determine a recommended feeding schedule. The smart apparatus system can remind the caretakers to feed the user, monitor the quantity of food and liquid that are placed in the smart tableware apparatuses and the consumption of the food and water by the user and transmit reports to the caretaker's computing device(s). The smart tableware apparatus system can maintain the recommended feeding schedule to keep the user within the healthy weight range or adjust the feeding schedule to bring the user's weight within the healthy weight range.

A pet watering fountain includes a bowl having a wall extending to a floor. The floor includes a lower area defining a sump with a sump floor. The sump floor has a height lower than the height of the surrounding portion of the floor. The housing divides the basin into a drinking basin and an interior basin. The drinking basin is accessible to an animal while the interior basin is located behind and underneath the housing and is not accessible to the animal. The pump has an inlet plate with inlet openings located near the bottom of the pump below the level of the bowl floor surrounding portion so that the bowl floor surrounding portion may be devoid of water yet the pump may still have enough water to keep it pumping and prevent it from overheating due to the water within the sump above the inlet openings.

A shape-shifting self-draining water-repelling hygienic indoor-outdoor slanting pet tree system comprises: adjustable legs, a rotatable pedestal, at least one shape-shifting rotatable log, at least one shape-shifting rotatable step, at least one shape-shifting rotatable branch, at least one shape-shifting rotatable hygienic platform, at least one shape-shifting rotatable condo, at least one shape-shifting rotatable hygienic cap, at least one shape-shifting rotatable connector for rotatably connecting all the components of the pet tree together, multiple rotatable wheels to allow the pet tree to be wheeled anywhere, and at least one removable water-repelling cover to cover the components of the pet tree. All the components of the pet tree can rotate 360 degrees (by water, wind, pet, and human forces applied on the inside and outside of the pet tree) to allow users to customize the tree shapes, have internal doors to allow pets to move around from one component to another inside the tree, are made of water-repelling material, and have water-draining holes to allow the tree to be hosed down and able to be used indoor and outdoor.
