  • Patent number: 7234505
    Abstract: A metal flow system, for use in casting aluminium alloy using a pressure casting machine, is provided by a component of a die or mould assembly, for the machine, which defines a die cavity. The component defines at least part of an alloy flow path for the flow of aluminium alloy from a pressurized source of substantially molten aluminium alloy of the machine to the die cavity. The flow path includes at least one runner and a controlled expansion port, referred to also as a CEP, which has an inlet through which the CEP is able to receive aluminium alloy from the runner and an outlet through which aluminium alloy is able to flow from the CEP for filling the die cavity.

  • Patent number: 6994753
    Abstract: Apparatus and method for applying liquid coating to pellets in a flowing feed stream are provided. An incoming bulk material feed is conditioned to produce a ribbon-like agglomerated flow pattern, and the bulk material is passed through a first spray section which coats an exposed surface of the pellets flowing therethrough. The flow direction is reversed in a second spray station, which operates to expose an opposite surface of the pellets, such that the second spray section coats substantially the remainder of the outer surface of the pellets.

  • Patent number: 6953257
    Abstract: An installation system for mounting outdoor lighting wherein there is provided a foundation member in the form of a mildly compressible pipe member which is mounted in the ground, and an adapter which may form an electrical connection box. A light standard can be mounted on the adapter which has a lower portion, at least a portion of the outer surface of the lower section being in the form of a section of a sphere for close reception in an open upper end of the pipe member. The adapter within the pipe member provides adjustment movement in a ball and socket fashion so that regardless of whether the pipe member is not accurately installed in the ground, the adapter can be moved to achieve vertical orientation of the light standard prior to clamping of the pipe member to prevent further relative movement between the standard and its foundation member.

  • Patent number: 6697803
    Abstract: New techniques for generating entries in a content addressable memory (CAM) capable of comparison operations such as “greater than” and “less than” decisions are described. The techniques can be used with binary or ternary CAMs. The number of CAM entries needed to implement such decisions is drastically reduced for both binary and ternary CAMs. In the case of binary CAMs, one or multiple searches are needed to perform the comparisons, while in the case of ternary CAMs a tradeoff between the number of CAM entries and the number of searches can be found. As an example, a method of classifying data networking packets is implemented using the new techniques. A packet classifier based on subfields of a packet header is also described.

The cooling water also flows through the interior of a duct tip (36) at the forward end of duct (31). The front end of central structure (33) which carries the swirl vanes (34) is internally water cooled by cooling water supplied forwardly through a central water flow passage (52) from a water inlet (53) at the rear of the lance through to a nose (35) of the central structure.

  • Patent number: RE38584
    Abstract: A meteorological information system useable by aircraft pilots and others. A receiver-calculator unit receives raw meteorological data and site-specific physical data from a ground-based weather station having a signal transmitter for broadcasting signals conveying data about weather conditions at the station. The transmitted raw data signals are received by the receiver-calculator unit in the aircraft. The receiver-calculator unit may feature an input with which the operator inputs information about the physical character, such as the heading, of the runway of interest. The receiver-calculator unit processes both received raw weather data and received site-specific physical data, and/or operator-input data, to derive additional meteorological information. The raw and derived weather conditions information is displayed by the unit to be available to the aircraft pilot during landing or take-off maneuvers.
