摘要:
Brake controllers typically require a microprocessor or some complex digital circuitry to achieve a proportional brake control signal suitable to control electric brakes on a towed vehicle. These components can be difficult to manufacture and can be expensive. Therefore, a brake controller comprises a case, a positioning member held by the case, and an accelerometer attached to the positioning member, wherein the positioning member is moveable to position the accelerometer in an operable position

A method, apparatus, and system for determining the integrity of a sealed container utilizing one or more force signals which are converted into absolute force units is disclosed, providing a method that uses quantitative parameters, and can be validated. The force signals are measured in multiple data collection channels, and can be individually enabled or disabled by an operator to facilitate machine setup and troubleshooting. A user interface provides a display showing the force applied during the container-sealing process, as well as summary information regarding the status of multiple container-sealing machines in a production line.

A pressing apparatus for producing a food service paperboard container from a paperboard blank so that the paperboard container possesses an overturned rim provided with folds includes a first die and a second die that are movable relative to one another. The first die includes a first base and a first platform that is movable with respect to the first base, with the first base having a curved surface for engaging the outer periphery of the paperboard blank. The second die is positioned in opposing relation to the first die and includes a second base and a second platform that is movable with respect to the second base. The second die is movable with respect to the first die and the second base has a curved surface for engaging the outer periphery of the paperboard blank so that the outer periphery of the paperboard blank is pressed between the curved surface of the first base and the curved surface of the second base. A first cast-in heater is mounted within a recess in the first die and includes a resistor wire embedded within a thermally conductive cast-in material. A second cast-in heater is mounted within a recess in the second die and includes a resistor wire embedded within a thermally conductive cast-in material.

A method of contact level assist feature OPC layout is described using frequency model-based approach. Through low-pass spatial frequency filtering of a contact mask function, the local influence of zero diffraction energy can be determined. By determining isofocal intensity threshold requirements of an imaging process, a contact mask equalizing function can be designed. This provides the basis for frequency model-based contact assist feature layout. By choosing contact assist feature parameters that meet the requirements of the equalizing function, through-pitch focus and dose matching is possible for large two dimensional contact mask fields. The concepts introduced also lead to additional contact assist feature options and design flexibility.
摘要:
A method of treating brines (10) comprising the steps of: pre-cooling the brines using a stream medium before further cooling the brines using a refrigerant. This further cooling of the brines continues until a first temperature equal to a eutectic freezing point of a mineral salt suspended in the brines is reached, such that the brines are transformed into an ice slurry. The ice is then separated from the ice slurry for use as part of the pre-cooling step. The remainder of the ice slurry is filtered to recover crystallised mineral salts suspended therein. A system for performing the method is also described.
摘要:
Second-stage nozzles have vanes including airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in inches in Table I with the X, Y and Z values commencing at the radially innermost aerodynamic section of the airfoil and then made relative to that section for the Z coordinate values. The X, Y and Z values may be scaled as a function of the same constant or number to provide a scaled-up or scaled-down airfoil section for the nozzle.
摘要:
A computer system may manage orders for goods from a plurality of purchasers. The computer system may receive the orders, calculate an approximate volume that the goods which are the subject of each order would collectively occupy during shipment, and compare each calculated approximate volume to a pre-determine maximum allowed volume that the purchaser of the order is permitted. The computer system may accept each order whose approximate volume does not exceed the maximum allowed volume for the purchaser of the order, or reject each order whose approximate volume exceeds this maximum allowed volume.
