  • Patent number: 10184824
    Abstract: A mechanical scale has a weighing basket with a platform having entrance and exit ends. A hanging assembly for supporting the weighing basket includes a break-over beam. A counterweight assembly is connected to the break-over beam and is adjustable to select a threshold scale weight required to trigger a scale-operated feature, such as a spray marking mechanism. The counterweight assembly has a weight selection device bracket pivotally mounted to the frame assembly about a pivot point, and a freely moveable counterweight mass supported by the bracket. The freely moveable counterweight mass is moveable from a first position to a second position when the threshold scale weight is exceeded in the weighing basket, thereby causing an abrupt triggering of the scale-operated feature when the threshold scale weight is exceeded in the weighing basket. The freely moveable counterweight mass is a rolling spherical member enclosed within a hollow chamber inside the bracket.

    Abstract: A safety bypass gate is provided for use with a livestock management system having a sorting scale arranged between watering and feeding areas. The safety bypass gate changes from a closed position to an open position to provide an emergency exit from the watering area when a condition exists that prevents animals from passing over the sorting scale. The safety bypass gate includes a pair of pivoting gate members and a channel member that fits over the top edges of the gate members to secure them closed. The channel member is attached to a pneumatic actuator that uses air pressure to hold the channel member in its locked position, and a spring return that moves the channel member to its unlocked position upon a drop in air pressure. Springs bias the gate members from their closed positions to their open positions when the channel member moves to its unlocked position.

The system uses a single method such as multi-dimensional single voxel(s) of MR, NMR, MRI, ultrasound, C.A.T. scan, CT scan, P.E.T. scan, or a combination of these, or any equivalent internal measuring device, on a single occasion, to evaluate the animal and determine a number of days the animal must be fed to reach a maximum value. The system also combines internal evaluation with an external animal evaluation system to refine the number of days remaining for the animal to reach a maximum value, and the system, when used in a feedlot, will direct the animal to a feed pen based on the number of days remaining for the animal to reach maximum value.

    Abstract: A system for weighing a plurality of quadruped animals is for use in a pen confining the animals. The pen has at least first and second segregated spaces with a first one-way chute allowing animal passage from the second space to the first space. A weighing station is located within a passage having an entrance and an exit, and that allows animal passage from the first area to the second area. The weighing station includes a weighing platform within the passage over which an animal must pass when passing from the first to the second space. The weighing platform has inlet and exit scales that support the weighing platform adjacent to inlet and exit ends thereof, and provides inlet and exit weight signals. A controller receives the inlet and exit weight signals and uses them in an iterative process to determine the presence of a single animal on the weighing platform. Once that determination is made, the sum of the inlet and exit weight values is very likely to accurately provide the animal weight.

    Abstract: A method and apparatus for treating animals that are milked in an automated milking system. For the animals involved or groups of such animals, there is stored a predetermined desired weight pattern for such animals or groups of animals, which weight pattern is based on the animal's actual weight pattern which extends over a relatively long period of time including, at least, each animal's last lactation period, into a computer memory. An animal is weighed in a milking compartment where it is simultaneously milked and fed two to four times in each twenty-four hour period. On the basis of the animal's ongoing weights, having in view its earlier established desired weight values, there is determined average actual weight values taking into account the weight variations due to contents of the animal's digestive tract and udder to provide expected variations around the average value.

  • Patent number: 5438960
    Abstract: A detection and weighing device for selectively distinguishing two groups of animals, such as for instance cocks and hens, one of the groups to be distinguished being provided with a detection element, for instance a label, consisting of or provided with amorphous magnetic material. This material is recognized with the aid of an alternating magnetic field and a receiving coil suitable for that purpose, and the presence or absence of the detection element, together with the weight determined by the weighing device on which the detection system is arranged, indicates whether an animal from one group or the other group is involved, so that, for instance, the average weight of the two groups can be determined. Instead of being used in combination with a weighing device, this detection device can also be used while being coupled to other presence-detection devices.
