Abstract: A portable system moving a debeaker apparatus within a barn to reduce the transportation and handling of a bird. A frame which holds the debeaker apparatus, a receiving chute, a staging cage, a delivery chute and a first and second storage baskets has wheels for easy movement from one location to another location. In a barn, an operator removes a plurality of birds from a starter cage and places the birds in the receiving chute which directs the birds to a platform in the staging cage. The platform has an inclined surface such that the birds have a tendency to face away from the operator. This orientation of the birds assists in the alignment with respect to a head retaining member of the debeaker apparatus. The operator selects a bird from the platform in a staging cage for presentation to the head retaining member associated with the debeaker apparatus. Once a bird is accepted by the head retaining member, a containment shield is resiliently positioned adjacent opening in the top or the return chute.

Abstract: A remotely located brake booster for supplying an input force to a pressurizing device to develop pressurized fluid to effect a brake application. The brake booster responds to an actuation signal in the form of pressurized fluid being communicated from a control apparatus activated by an operator. The brake booster has a housing with a bore and a piston located therein to define an operational chamber. The housing has an inlet port through which pressurized fluid from the control apparatus is receiving by the operational chamber. The piston moves from a rest position to an actuation position in response to pressurized fluid being received in the operational chamber to produce the input force for operating the pressurizing device.

Abstract: A secondary source of braking for large hydraulically braked vehicles utilizing the available power source (38) provided by typically available anti-skid and traction control braking systems. The invention improves the time response of a secondary braking traction control system by utilizing stored fluid in the low pressure anti-skid braking system accumulators (34) to provide for faster build of pressure by the pump motor (38). Fluid is stored and utilized based on vehicle behavior and operational states and is based upon the principal the traction control, anti-skid braking and secondary braking requirements are generally mutually exclusive. This allows for a decreased response time of the secondary braking system and also provides for improved initial cycle response of typical traction control events that utilize the system configuration.
