摘要:
An apparatus and method for consolidating a composite workpiece are provided. The apparatus includes an electromagnetic field generator for inducing a current and thereby heating a susceptor in thermal communication with the workpiece. The workpiece is supported by one or more support tools, each of which transmits the electromagnetic field so that the support tools are not substantially heated by the electromagnetic field. Thus, the time and energy required for heating the workpiece are reduced relative to conventional consolidation techniques.

An apparatus and method for forming a composite workpiece are provided. An electromagnetic field generator induces a current in a susceptor, thereby heating the workpiece in a die cavity. An elastomeric bladder in the cavity is inflated and urges the workpiece against a contour surface corresponding to a desired configuration of the workpiece. Coolant fluid can also be circulated through the die cavity to cool the workpiece. Thus, the workpiece can be heated, formed, and cooled quickly and without substantial heating of other components, thereby reducing the time and energy relative to conventional forming methods.

Coating production systems and methods which include ultrasonic dispersion and active cooling. The system includes a mixing reservoir and an ultrasonic disperser for ultrasonically dispersing an additive with another coating component within the mixing reservoir. The system also includes a heat exchanger in communication with the mixing reservoir to receive a mixture of the additive and another coating component from the mixing reservoir. The mixture is cooled by thermal energy transfer from the mixture to the heat exchanger. The cooled mixture is returned to the mixing reservoir.

Mechanism for shifting a bed between horizontal and upright positions includes a pair of spaced apart vertical lift means coupled to opposite sides of an adjacent end of the bed and means for fastening the mattress to the headboard. Operation of the lift means draws the bed to a fully vertical position with the bed being between the lift means and being flat against a wall. Support structure for the remote end of the bed includes rollers on pivoting legs which swing into alignment with the bed as the vertical position is approached and which swing outward as the bed is lowered. Continued lowering of the bed causes the legs to pivot past a perpendicular position whereby the legs are inclined when the bed is fully lowered and contact a stop to securely support the remote end without requiring any manual manipulations thereat.

摘要:
A method for pricing a trade comprising providing a user input for entering trade data, providing a structure for receiving the trade data and then transmitting the structure to a pricing system. The structure, now populated with both the trade data and the pricing data, is received from the pricing system and the trade data and pricing information is displayed. Advantageously, the structure is encrypted prior to transmitting it to the pricing system and decrypted when received from the pricing system. The pricing system records the data and the pricing information, which may be automatically entered into a trading system if and when the user agrees.
