Abstract: An improved glass railing anchor system for multiple glass panels in high-rise buildings which can experience hurricane strength winds, and which includes an elongated base member having two hollow wall sections which create a channel for receiving the glass panels. Aligned with and beneath the hollow wall sections are integral keyways which receive T-shaped anchors that also elevate the base member to allow for drainage. The anchors are slidable and can be selectively positioned for easy and secure installation. The base member, hollow wall sections, keyway and drainage areas can be integrally incorporated into a unitary device.

Abstract: An improved mounting structure for the posts of hand rail systems including a mounting arm member positioned within a sleeve monolithically formed within the inner chamber of the post. The sleeve includes a slit that allows for the outflow of water, thereby limiting corrosion and degrading of the post and mounting structure. A series of nubbed projections create grooves within the surface of the sleeve, to secure the mounting arm into the sleeve in a strong manner. A secure fit limits the amount of liquid trapped within the sleeve reducing corrosion. The mounting arm has smaller dimensions, reducing the chances that the arm comes into contact with support rods embedded within the concrete during installation. By avoiding contact with the support rods, concrete spalling is dramatically reduced, adding to the lifetime of the rail system.

Abstract: A corrosion resistant railing insert including a stainless steel upper body for insertion into a railing post and including channels for liquid drainage from the railing post, an elongated stainless steel mounting arm protruding from the upper body. The mounting arm has a smaller cross-sectional area than the upper body, which are integrally associated as a unitary device. The upper body is secured within a railing post while the mounting aim is inserted into a complimentary aperture or sleeve formed in a concrete substrate and secured therein with an adhesive.

Abstract: A method for using tilt-up panels with chamfered sides, extensions below the panels ad receptacles for removable eyelets approximately ? of the way up the panel. Inserts may be used between the panels to hold epoxy or other materials. The inserts may include a T-shaped form that obviates the need for caulking between the outside portions of the panels.

Abstract: The present invention provides, in one embodiment, an awning that permits light and air to enter the structure to which the awning is attached, that can be utilized to protect against major storms, and that can pass strict building code standards testing. The awning includes a perimeter framework that is adapted to receive a removable rigid support plate. In an alternate embodiment, the invention provides a shutter that is inexpensive, easy and quick to manufacture, that can provide protection against major storms, and that can pass strict building code standards testing. The shutter includes modular louver sections that have an integral rigid backing plate.

Abstract: An apparatus for detecting a loss of refrigerant and air pressure in a refrigeration/heat pump system having a low pressure refrigerant line and H.V.A.C. ducting, the apparatus comprising: a pressure switch fluidly communicating with the low pressure refrigerant line, responsive to pressure changes therein; a vacuum pressure switch fluidly communicating with a portion of the H.V.A.C. ducting, responsive to air pressure loss therein; a signaling circuit having an enabling DC power supply, operatively associated with the pressure switch and vacuum pressure switch, and two pairs of green and red LEDS for conveying to the operator when the refrigerant pressure drops below a predetermined valve indicating a refrigerant loss or clogged, dirty condenser or evaporator coils, and when air pressure within the H.V.A.C.

Abstract: This disclosure concerns a base receptical for releasably mounting standards for guard chains, and upon removal thereof receive and support decorative modular guard rails. A hollow sleeve bracket member is positioned on reinforcing rods or mesh to receive concrete for walks, verandas, stairs and the like, this hollow sleeve bracket receives a standard having a nut positioned thereon and a bolt extending through said standard and nut to nut to abut the sleeve bracket; and, upon tightening the bolt this temporary standard is firmly positioned in the sleeve bracket. By loosing the bolt the standard can be moved, and a permanent modular guard rail standard of a decorative nature inserted therein. A plurality of these sleeve brackets are preferably connected by one or more rods or rails, which are imbeded in the concrete when poured along with the major portion of the length of the sleeve bracket members.
