Abstract: A pilot control relay valve to change the directional flow of fluid to a piston (such as, for example, the piston of a chemical injection pump for injecting chemicals at a slow or rapid rate over a long period of time), but also allow the recovery of exhaust fluids under significant back pressure. The pilot control relay valve comprises an elongated valve member shiftable within a valve body between a first and second position. The first position allows communication of control fluid to a first pressure receiving surface while allowing exhausting of fluid from a third or opposing pressure receiving surface, thereby to initiate movement of the valve member against the back pressure of the exhaust fluid from its first position to a position equalizing the pressure acting on a second pressure receiving surface with the pressure of the control fluid, thereby causing the valve member to move to its second position. The valve member when it is in its second position allows communication with the third pressure receiving surface while allowing exhausting of fluid from the first pressure receiving surface for initially moving the valve member against the back pressure of the exhaust fluid from its second position while equalizing the pressure acting on the second pressure receiving surface to move the valve member to a position equalizing the pressure acting on the second pressure receiving surface with a pressure lower than the pressure of the control fluid for moving the valve member from its first position, whereby the operation is repeated ad infinitum.      Piping is connected to threaded exhaust ports in the valve body to communicate exhaust fluid to a reservoir where it is collected under pressure for further use.

Abstract: An adjustable cam track for an injection molding machine includes a set of guides coupled to a moveable platen for guiding the movement of space defining surfaces which are movably mounted to a stripper platen as it moves with respect to the movable platen.  A set of cam followers coupled to the space defining surfaces cause relative movement of each pair of surfaces to release molded articles previously striped from the molds of the molding machine.  A set of cam inserts engage the cam followers and are adjustably positionable with respect to the guides to adjust the point of release of the molded articles.  Each guide includes a pair of guide walls forming a channel defining two limits of position of the cam follower engaged therein.  Each cam insert is received between the guide walls and includes a pair of cam insert walls spaced apart by a distance about equal to the size of the cam follower engaged therein to define a path of movement for the cam follower between the two limits of position.  Each cam insert includes a first toothed rack, while a second toothed rack is removably fixed to each guide and engages the first toothed rack to fix the position of each cam insert relative to each guide only at certain preselected locations to coordinate the operation of all the cam followers thereby avoiding any wear imbalance.

Abstract: A method for processing a file containing a financial statement in uncoded format such as a financial statement stored in an ASCII file. The starting locations of the various types of financial tables in the financial statement as indicated by their table titles are identified by grammar descriptors. When all the table titles in the file are identified, a table title is then selected for processing. Typically after the table title, there are the associated column headers for the table, and they are analyzed and determined. Following the column headers, there are lines of text that are separated into line items, where each line item is composed of a label and/or one or more numbers corresponding to the label. With these line items, the next task is to parse these line items to verify that these line items make up the table and to identify the components of the financial table. A financial table is comprised of line items, subtotals, and grand totals. By recognizing the mathematical structure of the table, the relationship between the line items, subtotals, and grand totals can be readily understood and categorized.

Abstract: A heat recovery device recovers heat from a waste water pipe or the like. The device includes an evaporator chamber surrounding a length of the pipe. The chamber contains a refrigerant in both liquid and vapour states. A wick surrounding the pipe within the evaporator chamber extends into the liquid state refrigerant. A vapour outlet from the evaporator chamber above the liquid refrigerant leads to a condenser chamber around a container for liquid to be heated. The condenser chamber has an outlet connected to the evaporator chamber for delivering liquid refrigerant from the condenser chamber to the evaporator chamber. Heat in the pipe evaporates refrigerant from the wick. The evaporated refrigerant then travels into the condenser chamber where the cold surface of the water chamber extracts heat from the refrigerant and condenses it to be discharged back to the evaporator chamber. The water container in the condenser chamber is connected into the hot water system.

Abstract: When an operation such as opening or closing of a front flip cover or a key operation of communication-start or communication-end occurs, a controller acquires information for extraction or retraction of an antenna. Basing on the above information, the controller controls a motor driving by intermittently supplying motor driving signal by which the motor can rotate clockwise or counterclockwise during a preset time necessitated for fully extracting and retracting an antenna. While motor driving, if a blocking force applied to an antenna, the controller repeatedly stops supplying of the driving signals to the motor for a predetermined interval and then resumes supplying the signals. A gear unit is tightly coupled in a body with the motor, receives a rotating force from the motor shaft, and extracts and retracts an antenna. In addition, there is further provided a fixing element for fixing the motor and the gear unit to an antenna housing, which is able to absorb external impact transferred to the motor and the gear unit through an antenna and to absorb a vibration of the motor. When a front flip cover is opened or a communication-start key is pushed by a user to use a wireless telephone, the antenna is automatically extracted from the antenna housing, while when the front flip cover is closed or a communication-end key is pushed, the antenna is automatically retracted into the antenna housing.

Abstract: The invention provides a novel preheating apparatus and method for preheating a ferrous scrap mixture prior to feeding the scrap into a metallurgical furnance primarily using heat recovered from hot waste gases emitted from the furnace exhaust port, and simultaneously reducing contaminants from the scrap and from the waste gases, with concurrent downward flow of hot waste gases and downwardly descending scrap. The apparatus has a chamber, including a top compartment with a cold scrap input for depositing cold scrap into the top compartment and a hot waste gas inlet in flow communication with the furnace exhaust port. The chamber also has a bottom compartment with a heated scrap discharging mechanism for force delivering the heated scrap into the furnace and a waste gas outlet in flow communication with a vacuum exhaust for evacuating spent waste gas. Gas permeable gates are disposed between each chamber compartment and sequentially operate between a closed gate position and an open gate position, for concurrently receiving a gravity fed charge of scrap from the cold scrap input in a closed gate position, and during a predetermined dwell period supporting the scrap charge while hot waste gas flows downwardly from the hot gas inlet in the top compartment, permeates through the scrap charge and through the closed gates, and flows out the waste gas outlet in the bottom compartment. The gates mix the scrap as it falls and serve to control the gravitational descent of the scrap charge from the top compartment to the bottom compartment on expiry of the dwell period.
