摘要： An extraction fan has a housing mounted in a wall with an outlet duct extending through the wall to an outlet opening outside the wall. A damper flap is mounted on the fan suspended by a hinge at an upper edge so as to extend in a closed position across the opening and is movable to an open position under forward air flow from the fan, and tightly closes against a resilient deformable seal when the fan is shut off. A spring biasing cam applies inwards force to the damper flap to bias the damper flap into the closed position, and an outwards force also to bias the damper flap into the fully open position. The mounting plate includes a hood having a top wall extending over the top of the damper flap and a down-turned front flange extending parallel to the damper flap to a bottom edge.

摘要： An animal barn includes air inlets which are filtered to extract pathogens and a plurality of extraction fans for generating an air stream so as to draw replacement air into the containment area through the air inlets. Each fan has a housing mounted in a wall with an outlet duct extending through the wall to an outlet opening outside the wall. A damper flap is mounted on the fan suspended by a hinge at an upper edge so as to extend in a closed position across the opening in a mounting plate. The damper flap is movable to an open position under forward air flow from the fan and closes against a resilient deformable seal to seal the damper flap to prevent reverse flow of pathogen contaminated air through the fan housing when the fan is shut off. An adjustable abutment member can act to hold the flap partly open against opposing wind forces during low fan operation.

摘要： A boar cart for carrying a boar through alleyways of a sow insemination area for interaction with the sows during insemination is formed by a cage for containing the boar which includes a cage floor on which the boar stands, two sides each defined by vertical bars on a respective side of a longitudinal center line of the cage assembly for confining the boar so that the boar is maintained extending longitudinally of the cage, a cage front and a cage rear. The cage may be rigid or may be defined by a front portion and a rear portion connected together for pivotal articulated movement about a pivot coupling defining a vertical pivot axis arranged substantially at the center line such that the cage can articulate to the left and to the right for navigating left and right corners in the alleyways while the boar is retained in the cage. The cage front and cage rear are each defined by two panels pivotally mounted at on end to the cage side and pivotally connected at the other end to a link holds the other ends spaced but which allows the panels to pivot side to side in the corner of a narrow alleyway.

摘要： The number of piglets dying at birth is reduced by providing a temperature sensor in a farrowing crate at the piglet area thereof on a movable cover so that, when the sow is expected to give birth, the sensor is located in the crate at a location to detect the presence of one or more piglets after birth. On detection by a control unit using the sensor signal of the one or more piglets, the sensor communicates a signal to a pager carried by an operator indicating to the operator that birth of piglets is in progress and activates a heating lamp for the piglets in the pen to attract them away from the area of the sow to reduce crushing. The control unit and the sensor also control the heat output. The cover can slide along the piglet area and can lift to expose the piglet area.

摘要： A process control system includes a high speed serial backbone communications network, interconnecting a plurality of microprocessor based nodes that each act as the master to a high speed serial branch network comprising device controllers, such as air flow valve controllers and transducers. The primary network may operate in a time division multiplex mode whereby a node acting as a synchronizing station periodically issues a synchronizing signal that commands each node to execute a branch network control sequence, during which each node gathers and operates upon data it collects from the device controllers within its branch network, and issues commands based thereon to the branch network. An ensuing communications sequence also triggered by the synchronizing signal enables each node on the primary network to transmit a command or a response to any other node and, through such other node, to any device controller in any branch network of the system. Serial ports on each node permit user access from any node on the primary network to any other point on the system for purposes of monitoring and control. Serial ports on each device controller permit user access to local device parameters.
