Abstract: A near-boiler piping loop apparatus is provided including a primary/secondary piping loop interface apparatus having a unitary construction including a secondary loop shut-off valve, drain valve and drain port in each branch of a secondary loop for connection to a boiler. Supply branch piping and return branch piping connects the interface apparatus to the boiler and provides attachment points for auxiliary plumbing equipment. The apparatus is adapted to connect to pump in variable orientations using rotatable flanges on the interface apparatus and on a wye strainer in the secondary loop supply branch and includes a union fitting attached to the interface apparatus. The union fitting provides a mounting hole for a temperature or pressure gauge.

Abstract: The invention concerns a carrier plate holding an abrading element, for detachable mounting on a rotatably mounted abrading plate driven during use, for abrading stone or concrete floors, which carrier plate has sides which form an acute angle with each other. The sides have flanges which are formed for surrounding engagement with a shoulder arranged on the abrading plate so that the carrier plate can be fixed on the abrading plate with an engagement based on form and friction.

Abstract: A rotatable flange structure is provided which can be installed over the front-mating surface of a plumbing and heating apparatus. A retaining ring fits inside the grooves on the outer edge of a flange portion and on the inner edge of a mounting plate to keep the mounting plate attached to the flange portion. The flange portion can be easily assembled to the rotatable mounting plate and can be removed from the rotatable mounting plate in only one direction. The retaining ring is compressed slightly by the flange portion as the rotatable mounting plate is installed to the flange portion over its front side and snaps back out into the mounting plate groove to complete the assembly and retain the mounting plate to the flange portion.

Abstract: A rotatable flange structure is provided which is integrally or monolithically formed with a Y-strainer. The rotatable flange structure can be installed over the front-mating surface of the Y-strainer. A retaining ring fits inside the grooves on the outer edge of a flange portion and on the inner edge of a mounting plate to keep the mounting plate attached to the flange portion. The flange portion can be assembled to the mounting plate and can be removed from the mounting plate in only one direction. The mounting plate may be prevented from completely being removed from the Y-strainer by an angular branch of the Y-strainer body. The retaining ring is compressed slightly by the flange portion as the rotatable mounting plate is installed to the flange portion and snaps back out into the mounting plate groove to complete the assembly and retain the mounting plate to the flange portion.

Abstract: A primary-secondary loop piping system includes at least one boiler in fluid communication with a primary piping loop and at least one primary loop pump in the primary piping loop. At least one secondary piping loop branches away from the primary loop and returns downstream to the primary loop via a pair of closely spaced tees in a primary/secondary piping loop interface apparatus. The primary/secondary piping loop interface apparatus is of unitary construction and includes a secondary loop shut-off valve, drain valve and drain port in each branch of each secondary loop in which it is installed.

Abstract: A primary/secondary loop adapter comprising a valve body having a first primary loop port, a second primary loop port, a first secondary loop port and a second secondary loop port is provided. The secondary loop ports are disposed at respective ends or a linear secondary loop portion of the valve body. A primary loop portion of the valve body is formed by a pair of closely spaced tees extending from the secondary loop portion. At least one main valve portion is disposed in a first one of the tees. A drain/venting valve portion may extend from one or more of the main valve portions. One or both of the primary loop ports may include a flange for connecting to an apparatus in the primary loop.

Abstract: A method and apparatus detects that when properties are changed within an entry a changed property is not defaulted by another changed property. The present invention determines what properties in the data have been changed. The present invention accesses a database to obtain the defaulting definitions for the properties that were changed. Then the present invention identifies, within each defaulting definition for a changed property, properties that it is dependent upon that are also being changed by the data. A defaulting table is generated based upon the defaulting definitions for the changed properties, and the defaulting logic is executed based on this table.

Abstract: Methods and data structures for the management of a data entity during an entity lifecycle. An entity having a property and at least one operation having a property characteristic are defined. The operation may be performed on the property according to the characteristic. An entity lifecycle having the at least one operation is created, and a user interface is rendered according to the operation.
