摘要:
A uniformly preset spring force pre-load among a number of identical solenoid actuated valve assemblies (28) by uniquely adjusting the spring pocket length (L) of each respective plunger (12) to accommodate a respective spring (20) which is uniquely mated thereto. This adjustment is accomplished using a two-component plunger (12) consisting of a plunger body (14) having a central bore (22) and a rod (18) slidably located within the central bore. The rod (18) is press-fit into the central bore (22), and the spring pocket includes a portion of the central bore unoccupied by the rod. By pressing the rod (18) a selected distance into the central bore (22), a precisely set spring pocket is obtained which is uniquely correct for a selected spring (20), in that the selected spring is compressed to a precisely preset spring force pre-load. The adjusted plunger (12) and spring (20) are uniquely assigned to each other to collectively form a customized plunger assembly (10) having a preset spring force pre-load, whereupon a valve assembly (28) is manufacturable therewith having the precisely preset spring force pre-load. In carrying-out the adjustment of the plunger (12) with respect to a specific spring (20), the rod is pressed into the bore by a controllable source of force, such as for example provided by a stepper motor (88), and the spring force pre-load is monitored by a load cell (78) to ascertain when the desired spring force pre-load is achieved. Monitoring and force control is preferably automatic via a micro-controller (98), but may be manual.

摘要:
A system protects a computing device from potentially harmful code in a document by receiving a data structure representation of the document and adding dynamically one or more definitions of potentially harmful active content to an editable configuration file. Each definition identifies potentially harmful active content and specifies an action to be performed on that potentially harmful active content if that potentially harmful active content is found in the document. The editable configuration file is parsed to generate a data structure representation of the one or more definitions in the editable configuration file. The data structure representation of the document is compared with the data structure representation of the one or more definitions of potentially harmful active content to identify potentially harmful active content within the document. The document is modified to render harmless any identified potentially harmful active content before presenting the document to the computing device.
