Abstract:
Apparatus for apportioning a cut of whole muscle meat into a product having margins of a select size and an excess trim portion. An upper die is provided as having a forward blade portion and a rearward compression surface extending about the blade portion. The blade portion defines with the compression surface at least a portion of the margins of the product. At least one lower platen is provided as having a support surface for receiving the cut of whole muscle meat thereon. The support surface has a slot configured to receive the blade portion therewithin intermediate a first and second side wall thereof, and a bearing surface configured to abuttingly engage the compression surface. An actuator assembly moves the upper die from a first position spaced above the lower platen to a second position wherein the compression surface abuttingly engages the bearing surface. The compressive engagement between the upper die and lower platen is effective to apportion the cut of whole muscle meat into the product and trim portion.
Abstract:
A disclosed lift axle is suitable for a vehicle that has a first wheel for supporting the vehicle on a road surface. The lift axle system includes a lift mechanism that is coupled to the vehicle and is configured to reciprocate an axle between a stowed position and deployed position. The lift axle system further includes a second wheel coupled to the axle. The second wheel engages the road surface when the lift mechanism is in the deployed position, and the second wheel is disengaged from the road surface when the lift mechanism is in the stowed position. The second wheel has a lower rolling resistance than the first wheel.
Abstract:
Drag reducing systems for vehicles are provided. In one aspect, a drag reducing system generally includes an airfoil rotatably couplable to the vehicle and configured to provide a lift force to the vehicle as a result of differential airflow velocity over the upper surface with respect to the lower surface. The drag reducing system may further include a flow alignment vane to rotationally align the airfoil to the direction of airflow. In another aspect, a drag reducing system generally includes an air vane hingedly couplable to a surface of a vehicle and configured to rotate from a first stowed position to second deployed position. The air vane includes a flared leading portion to provide a force to bias the air vane toward the first position and a flared lateral portion to provide a force to rotate the air vane to the second deployed position.
Abstract:
An aerodynamic component in the form of, for example, a fairing is provided. The fairing is attached or otherwise positioned at the entry of or within the fender well of the vehicle. In use, the fender well fairing aims to block entry of airflow into the interior area of the vehicle as well as reduces or eliminates direct impingement against interior surfaces of the fender well. This improves air flow, thereby reducing drag.
Abstract:
An aerodynamic component is provided in the form of one or more ground skirt sections attached to one or more underbody fairings (e.g., trailer side skirts, tractor side fairings, etc.) of a vehicle. In use, the ground effects skirt sections improve air flow underneath the vehicle, thereby reducing drag.
Abstract:
Trailers, such as semi-trailers, having configurations that improve the aerodynamic efficiency thereof are provided. In some examples, aerodynamically configured trailers are provided that maintain standard cargo capacity. To improve the aerodynamic efficiency, the rearward end of the trailer in some embodiments include a downward cant or slope. In use, the rearward cant or slope reduces the low-pressure region that trails the end of the trailer, thereby reducing pressure drag. In accordance with another aspect, to accommodate loading and unloading of the downwardly canting or sloping trailer, examples of the trailers may also be equipped with “sliding trailer axle” and/or extended travel landing gear so as to allow the trailer to interface with standard loading dock heights as well as rampless ground loading/unloading.
Abstract:
Systems and methods are disclosed for improving the aerodynamic efficiency (e.g., reduce drag) on vehicles, such as class 8 tractors. In some disclosed examples, the systems and methods utilize exhausted gases from an internal combustion engine of the vehicle to direct a stream of gas forwardly of the vehicle. In other disclosed examples, the systems and methods utilize generated air flow from, for example, electric fans, engine driven or pneumatically/hydraulically driven pumps, etc., to direct a stream of gas forwardly of the vehicle for reducing the aerodynamic drag on vehicles. In yet other disclosed examples, the systems and methods utilize a unique configuration of the vehicle's radiator fan(s) in order to direct a stream of gas forwardly of the vehicle.
Abstract:
Disclosed are apparatus and methods for designing electrical contact for a bipolar emitter structure. The area of an emitter structure (106, 306, 400, 404) and the required current density throughput of an electrical contact structure (108, 308, 402, 406) are determined. A required electrical contact area is determined based on the required current density, and the electrical contact structure is then designed to minimize the required electrical contact area with respect to the emitter structure area.
Abstract:
The invention relates generally to an improvement to a rotary joint and stationary siphon system typically for use in the papermaking process. Disclosed is a siphon support that has a bearing that rotatably engages with a siphon and flow openings that allow for steam flow from the rotary joint to the interior of a heat exchange roll. Further disclosed is a support device with a flow section that receives steam from the rotary joint and transmits it on to the heat exchange roll, wherein the flow section raises the pressure differential across the rotary joint by less than about 2 p.s.i. The support device is also only attached to the rotary joint and siphon thereby reduces the cantilever effect of the stationary siphon. Further disclosed are systems for papermaking that include the siphon support and rotary joint; the siphon support and stationary siphon; and the support, rotary joint and siphon. Further disclosed is a method of assembly wherein the support device is attached to a rotary joint and siphon.
