Precast utility enclosure aprons for buried utility enclosures that have an angled top surface to direct water, ice and debris away from the center of the apron and to limit damage to the apron and utility enclosure caused by impacts to the apron.

A method of fabricating panels includes providing an insert having an interior portion with a top portion and a positioning stop opposite the top portion, and an exterior portion including a fastener hem. Further, the method includes placing the insert in a mold such that only the fastener hem and the positioning stop contact the mold and centering the insert in the mold with the top portion and the positioning stop. The method also includes filling the mold with a casting material such that the interior portion is submerged in the casting material including the top portion, but some of the positioning stop is not submerged in the casting material, curing the casting material to form a panel on the insert, and removing the panel form the mold.

The present invention relates to an electrostatic chuck heater having a bipolar structure, the electrostatic chuck heater comprising: a heater body having an internal electrode and an external electrode for selectively performing any one of an RF grounding function and an electrostatic chuck function according to a semiconductor process mode; and a heater support mounted below the heater body so as to support the heater body.

A method of forming a coating includes providing a mold that has a flexible wall that defines a mold cavity, inserting a component that is to be coated into the mold cavity, the component having a component surface roughness and there being a coating gap defined between the component and the flexible wall of the mold cavity, introducing a molding slurry into the mold cavity, the molding slurry filling the coating gap and contacting the component so as to overcoat the component surface roughness, solidifying the molding slurry to form a green coating on the component, and consolidating the green coating to form a final coating on the component, the final coating having a coating surface roughness that is less than the component surface roughness.

An adjustable railing post-to-substrate embed system for anchoring a railing post having a railing base with plural railing base anchor holes includes: a plate, having anchor holes; a plurality of nuts, a first end of each nut being arranged proximate a respective one of the anchor holes, the first end of each nut being configured to be selectively and removably threadingly engaged, via the respective anchor hole, with one selected from the group consisting of: respective upper protective bolts, and respective bolts of the railing base; and a plurality of anchors, each being configured to adjustably threadingly engage a second end of a respective one of the nuts, distal the respective anchor hole, each of the anchors being individually adjustable in length by threadable engagement with the second end of the respective one of the nuts.

Concrete coupling assembly comprises a base holder for being attached to a concrete forming surface, the base holder including a central opening; a coupler having one end disposed within the central opening, the coupler having an axis for being positioned substantially transverse to the forming surface, the coupler having first and second threaded bores through the one end for attachment of a threaded rod; and a separate anchor body threadedly attached to another end of the coupler.

The present invention relates to a method for making a composite panel comprising a pourable and settable base material, preferably cementitious mortar, and a plurality of through elements (10) made of glass for transmitting light between two base surfaces (1,1′) of the panel (1). The method includes making a semi-finished product comprising a central body (50) which incorporates the through elements (10), which emerge from two mutually opposite main surfaces (51,52). In particular, the method includes making the semi-finished product by defining two containing frames, mutually opposite with respect to the body, each of which emerges from one of the central surfaces. The method includes closing the semi-finished product between two containing elements so as to define two half-spaces, each of which at least partially delimited by said containing frames. The method then includes filling each half-space with cementitious mortar and removing the manufactured item which is made, after the mortar has set. Finally, the method includes finishing such a manufactured item by eliminating the containing frames from the semi-finished product, the body of which remains incorporated in the structure of the panel.

An adjustable railing post-to-substrate embed system for anchoring a railing post having a railing base with plural railing base anchor holes includes: a plate, having anchor holes; a plurality of nuts, a first end of each nut being arranged proximate a respective one of the anchor holes, the first end of each nut being configured to be selectively and removably threadingly engaged, via the respective anchor hole, with one selected from the group consisting of: respective upper protective bolts, and respective bolts of the railing base; and a plurality of anchors, each being configured to adjustably threadingly engage a second end of a respective one of the nuts, distal the respective anchor hole, each of the anchors being individually adjustable in length by threadable engagement with the second end of the respective one of the nuts.

A catch basin trap for attachment to an opening in a side wall of a catch basin. The catch basin trap has a body with a front side for facing outside the catch basin, and a back for side facing inside the catch basin. The body defines a chamber, an inlet opening in the back side, and an outlet opening in the front side. A collapsible outlet pipe connector is attached to the outlet opening, configured to be manipulated from a collapsed configuration to an extended configuration defining a discharge end for coupling to an outlet pipe positioned outside the catch basin. The collapsed configuration stows the collapsible outlet pipe connector within the body, and the extended configuration permits watertight coupling of the discharge end to the outlet pipe. A method of installing a catch basin trap, and a method of making a concrete catch basin are also disclosed.

A hollow core element forming system including a measuring device configured to determine a location of a welding plate assembly on a casting bed. The welding plate assembly being connected to one or more prestressed strands. A hollow core forming mechanism has a strand guide located at a leading end of a support frame of the hollow core forming mechanism. The strand guide is configured to engage the one or more prestressed strands when the strand guide is in a closed position and to disengage the one or more prestressed strands when the strand guide is in an open position without interference between the strand guide and the welding plate assembly. A strand guide controller unit causes the strand guide to rotate between the open position and the closed position based on the location of the strand guide relative to the welding plate assembly.
