Abstract: A package used for storing food and fluid having a food compartment and a drainage compartment, and methods of use and manufacture thereof. The food compartment and the drainage compartment are separated by one or more inner seals or divider walls having one or more passages. The divider permits fluid to flow from the food compartment to the drainage compartment, and to restrict fluid from flowing from the drainage compartment to the food compartment. This provides a package which can reduce the amount of fluid in the food compartment and facilitate removal of the food product from the food compartment, such as by upending the package, without also removing fluid from the drainage compartment with the food.

Abstract: A method and system for facilitating skateboard and other types of play about a synthetic flooring system, wherein one or more skate components is provided and configured for such use. The skate components may be modular in form, or stand-alone components. In addition, the skate components are intended to interact with the synthetic flooring system, which is configured to enable skateboards, in-line skates, bikes, scooters, and others to traverse across the provided contact surface in a similar manner as with traditional surfaces, such as concrete. As such, the synthetic flooring system is configured with a hard, flat contact surface that is preferably non-abrasive. A pliable layer is provided on the various skate components, and is configured to provide a non-slip interface between the contact surface of the synthetic flooring system and the skate component.

Abstract: An apparatus for dielectric welding has an opposed pair of relatively movable electrodes (14, 12), each incorporating an electrically conducting element with a working surface close to and opposed to that of the other electrode. There is a gap (15) between the electrodes, such that a material to be welded may be placed in the gap and may be pressed between the electrodes, and radio frequency signals are supplied (16, 18) to the electrodes. At least one of the electrodes (14) incorporates a layer (14b) of dielectric material covering the conducting element (14a) both on the working surface and on surfaces which are alongside the working surface, so that the dielectric material (14b) defines at least part of the gap (15). The thickness covering the working surface is significantly less than that covering the alongside surfaces.

Abstract: A metering valve for a work machine hydraulic system is disclosed. The metering valve has an inlet and an outlet, a main poppet, and a solenoid-operated pilot element. The main poppet is movable to pass fluid from the inlet to the outlet, and to block fluid from the inlet to the outlet. The solenoid-operated pilot element is movable between a first position at which pressurized fluid from the inlet pressurizes a control chamber in communication with a control end of the main poppet to urge the main poppet toward the flow-blocking position, and a second position at which the control chamber is communicated with a drain to move the main poppet toward the flow-passing position. The metering valve also has a relief valve element configured to drain pressurized fluid from the control chamber to move the main poppet toward the flow-passing position in response to a pressure at the inlet exceeding a predetermined pressure.

Abstract: A shadow mask for depositing solder bumps includes additional dummy holes located adjacent holes corresponding to most of the perimeter chips of the wafer. The additional dummy provide more uniform plasma etching of contacts of the wafer, improve etching of contacts of perimeter chips, and lower contact resistance of contacts of perimeter chips. The extra holes also provide solder bumps outside the perimeter chips that can be used to support a second shadow mask for deposition of an additional material, such as tin, on the reflowed solder bumps for mounting the chips on a plastic substrate at low temperature. An improved mask to wafer alignment aid is formed from standard solder bumps. The improved alignment aid avoids damage to test probes and provides improved course alignment.

Abstract: A metering valve for a work machine hydraulic system is disclosed. The metering valve has a valve body with an inlet and an outlet. The metering valve also has a main poppet disposed within the valve body between the inlet and the outlet. The main poppet has a nose end and a chamber end, and is movable between a flow-passing position at which fluid flows from the inlet to the outlet, and a flow-blocking position at which fluid flow between the inlet and outlet is blocked. The metering valve also has a pilot element movable to selectively communicate the chamber end of the main poppet with a drain, thereby affecting movement of the main poppet between the flow-passing and flow-blocking positions. The metering valve further has a solenoid mechanism operable to move the pilot element. The position of the pilot element is affected by a fluid pressure at the inlet.
