Title: Degating technique for clustered castings made by ecp
Inventor: MCPHERSON JAMES C
IPC: B22D31/00
Filed: 1988-04-26
Granted: 1993-05-18
Abstract: Abstract of the Disclosure A method is disclosed of degating clustered metal castings produced by ECP in which molten metal is gravity poured into a dry, unbonded sand mold for solidification, the mold containing a plurality of consumable foam patterns interconnected by a complex centralized gating system.  The method is improved by forcing purge air through the unbonded sand mold just prior to the solidification of the core metal of the gating system, the purge air being forced into such mold at a predetermined pressure (such as 80-120 psi) and for a period of time (such as 10-20 seconds), causing the gating system to disintegrate into pieces or beads of metal.  The elapsed period of time from the moment of pouring the molten metal into the mold to the moment at which the purge air is injected into the mold is critical and for certain metals is usually in the range of 3-5.7 minutes.

Abstract: ABSTRACT         A mechanical anchor including an expansion shell and an ex-pansion plug positioned in the shell is engaged with the end of a bar having helically extending rib segments formed on the outer surface of the bar.   m e expansion plug has an internal bore defining a wall having a configuration to receive and mate with the helically extending rib seg-ments formed on the outer surface of the bar.  me mechanical anchor and a portion of the bar are inserted in a bore hole drilled in a rock formation and, upon rotation of the bar in a preselected direction, the expansion plug nonrotatably moves down the bar to expand the shell into engagement with the bore hole wall. As the shell engages the bore hole wall, the bar is mechanically anchored within the bore hole by the mechanical anchor. If it is desired to combine mechanical and chemical anchoring of the bar within the bore hole, the expansion plug is provided with a displaceable stop means positioned in the expansion plug bore, and a curable, two component bonding material is positioned in the bore hole ahead of the mechanical anchor.   The stop means permits initial rotation of the mechanical anchor and ribbed bar within the bore hole to mix the bonding material components before the expansion shell is expanded.  In addition, various other embodiments of a bar having helically extending rib segments formed on the outer surface of the bar and anchored in a bore hole are disclosed herein.

Granted: 1992-08-04
Abstract: ABSTRACT     A method for automatically completing the entry of the retention and deletion criteria employed by an interactive information handl-ing system to manage the automatic retention and deletion of a relatively large number of electronic documents that are stored in said system by a plurality of end users each of which has an inter-active terminal connected to the system that includes a keyboard and a display device; The method provides a screen image on the display device in response to the end user advising the system that he wants to assign retention and deletion information to an electronic document that he wants the system to store. The screen image prompts the end user for a set of required criteria and allows the interactive entry of one or more criteria by the end user directly. The remaining criteria that are not entered directly by the end user are entered automatically based on a logical analysis by said system involving the identity of the criteria that was entered directly and pre-established information stored in said system.      In the preferred embodiment the criteria include a document label, an ownership label, a document expiration date and an ownership expiration date. Information stored in the system involved in the automatic entry process includes allowable document and ownership labels personalized for each end user and allowable expiration dates or ranges for each label. Also stored in the system are rules that allow a logical analysis to select a default criteria and to verify any information that was entered directly by the end user.     Documents mab be automatically retained and deleted by process-ing the expiration date criteria associated with each document relative to a current date according to various strategies.

Abstract: An article for performing solid-phase immunological assays and methods for performing assays utilizing the article of the invention. A solid-phase support suitable for immunological assays is stained with an organic dye that has a net-positive charge and a hydrophobic aromatic ring structure. An immunologically reactive component having a net-negative charge is immobilized by the dye to the support through non-covalent interactions. The immunologically reactive component is tightly bound by the organic dye. This is advantageous when performing immunological assays utilizing automated washing instruments. A sample of a biological fluid is added to the article having the immunologically reactive component bound thereto to detect the presence of antigens or antibodies in the biological fluid specific for the bound immunological component. The presence of the antigen-antibody complex may be determined by any known method.

Abstract: ABSTRACT OF THE DISCLOSURE     A hydraulic control system for controlling a retainer valve in an underwater well test system.  The control system is contained in a housing in the test string above the retainer valve.  The control system and valve are operated by a surface control manifold via control conduits extending between the manifold and control system housing. The system provides opening and closing and very quick closure of the retainer valve by eliminating the requirement for closing pressure to be conducted through a long conduit from surface and by utilizing well pressure to close the valve and lock the valve closed.          One embodiment of the control system requires a pressure pulse from surface to start quick retainer valve closure.  Another embodiment of the control system monitors control conduits for loss of pressure while the retainer valve is open and auto-matically closes the valve on loss of control pressure.  This control system permits killing fluid to be pumped through the retainer valve into the well after automatic closure or control system operation to reopen the valve and monitor.     (3690Y)

Abstract: APPARATUS AND METHOD FOR MONITORING POWER                ABSTRACT OF THE DISCLOSURE A power monitor for determining real and imaginary power associated with one or more line signals samples a plurality of line cycles during an observation window to generate a plurality of voltage-current sample sets for each line cycle.  The sampling of the sample sets is timed such that the voltage-current sample sets are taken at different relative time positions.  The power monitor stores incoming voltage-current sample data in one memory area and concurrently analyzes sample data already stored in another memory area.  Deletion of sample data is not permitted until transient analysis of such data is complete.         In another embodiment, the power monitor includes a working data memory area coupled to the sampling circuitry such that the sample sets occurring during each observation window are stored in the working data memory area in interleaved fashion to simulate a single cycle of data.  This power monitor further includes a transient data area, coupled to the sampling circuitry, for storing the sample sets occurring during an observation window in a non-interleaved or sequential fashion.  Power analysis is conducted on the sample sets in the working data memory area unless a power transient is sensed.  Upon sensing a transient, data from the transient data area is provided for analysis.
