Abstract: A grinding rod chemistry enhances wearability and durability of a steel rod and comprises levels of carbon to achieve a surface hardness in excess of 55 Rockwell C and levels of chromium which achieve significant depth in the formed outer martensite shell. The grinding rod has a core greater than 99% pearlite with a hardness less than 45 Rockwell C and the end portions of the rod are soft and have a hardness less than 35 Rockwell C. The steel bar of the selected chemistry is treated by reheating to above its austenitising temperature, transferring with minimal cooling to an open tubular quench vessel while securing the bar in the vessel to minimize bar warping, introducing quench water into the inlet end of the vessel and passing the liquid through the vessel to ensure uniform heat removal. The outer martensite shell is tempered by allowing the bar to soak back after quenching. The bar end portions are reheated in a furnace to elevate the end portions above the austenitising temperature and air cooling each end portion to provide the engineered end portion hardness of less than 35 Rockwell C.

Title: Method for making three-dimensional, macroscopically-expanded webs having improved functional surfaces
Inventor: DIRK RAYMOND JOHN
IPC: A61F13/511
Filed: 1996-12-13
Granted: 2001-07-31
Abstract: The present invention provides a process for forming a three-dimensional, macroscopically-expanded, fluid pervious web (70) having an improved functional surface comprised of a sheet of polymeric material having a first surface and a second surface. A plurality of discrete deposits of a water resistant resinous material having a pre-determined open time are deposited on the first surface of the sheet. The deposits of resinous material are drawn upwardly from the first surface of the sheet to form corresponding fibrils (54) during the open time. After resinous material has cured, the sheet is fed onto a forming structure having opposed surfaces such that the sheet is in contact with the forming structure. The forming structure exhibits a multiplicity of apertures which place the opposed surfaces of the forming structure in fluid communication with one another. A fluid pressure differential is applied across the thickness of the sheet which is sufficiently great as to cause the sheet to rupture in those areas coinciding with the apertures in the forming structure and to conform with the forming structure while substantially maintaining the orientation of the fibrils (54).  The printing and drawing steps are preferably accomplished via a screen printing roll, and the fluid pressure differential preferably comprises a high pressure jet of liquid.

Title: Self-adjusting tooth/adapter connection system for material displacement apparatus
Inventor: MARTIN WESLEY E
IPC: E02F9/28
Filed: 1999-09-03
Granted: 2005-03-15
Abstract: An excavation tooth point longitudinally extending along an axis and having a pocket area extending inwardly through a rear end thereof is telescoped onto a nose portion of an adapter structure by inserting the nose portion into the tooth point pocket area. The inserted nose portion has a tapered side opening therein that is positioned between a corresponding pair of similarly tapered tooth side wall openings. The tooth point is removably coupled to the adapter nose using an elongated, wedge shaped connector member which is inserted, small end first, through the generally aligned tooth and adapter openings. An internal passage longitudinally extends through the large connector member end and receives an inner portion of a force exerting member which compresses a spring within the passage, the spring in turn resiliently biasing an outer portion of the force exerting member into abutment with an interior surface portion of the tooth. The compressed spring, via the force exerting member, maintains the tooth point in an axially tightened orientation on the adapter nose, and automatically tightens the tooth further onto the adapter nose in response to tooth/adapter interface wear that would otherwise cause undesirable "play" between the tooth point and the adapter nose portion. The connector may be removed by simply rotating the force exerting member to move its outer portion out of abutment with its opposing interior surface portion of the tooth.

Abstract: A method in a telecommunications network having a configuration management system, of automatically populating a Private Numbering Plan (PNP) subscription with PNP  data. The method begins by defining a group comprising a plurality of members who subscribe to a PNP service (5-11), and automatically generating the PNP data for each of the plurality of group members when the group is defined. The PNP data may be generated by service management application software in the configuration management system. The PNP data may include an abbreviated number for each of the plurality of group members.  The abbreviated numbers may be generated by several methods including incremental number generation (5-37), random number generation (5-39), or by extracting the last "X"  digits of each group member's telephone number (5-42). The method then determines whether each generated abbreviated number is valid and unique (5-55). A  network operator may override an automatically generated number by manually inputting an abbreviated number which is valid and unique (5-57).
