Abstract: A de-bubbling slide is configured to fit in a dispensing vessel and capture, with a receiving element, a flow of fluid into the dispensing vessel from a fluid inlet. The receiving element of the de-bubbling slide directs the flow of fluid to a flow surface of the de-bubbling slide from which gas dissolved in the flow of fluid, or bubbles in the flow of fluid, escape from the fluid. Openings in an upper surface of the de-bubbling slide allow the escaped gas to exit the de-bubbling slide.

Abstract: A multi-phase separation apparatus shapes a fluid stream in a flow shaping line having a plurality of descending, vertically stacked curvilinear loops disposed along a fluid vessel vertical axis, stratifying the fluid stream into a primarily liquid component and a primarily gaseous component. At a point below plurality of loops, the primarily gaseous component is bled off from the primary liquid component. The primarily gaseous component may be introduced into a vortex cluster to further separate liquid entrained in the gaseous component, which separated liquid may then be combined back with the primarily liquid component. The vertically stacked curvilinear loops may be disposed within a fluid vessel to protect and insulate the loops or may be disposed about the exterior of the vessel. The vortex cluster system may be positioned within the vessel and may employ vortex tubes deployed along either a linear flow channel or a spiral flow channel.

Abstract: The present invention relates to the filtering of fumes emitted by industrial processes such as those used in iron and steel works, refineries, waste-to-energy plants and the like and in particular relates to a filtering device for fine and ultrafine dust particles and other polluting agents.

Abstract: Centrifugal air separators, systems including the same, and methods of separating gas are disclosed. Centrifugal air separators include a separation section configured to separate an input air stream into a clean air stream emitted from an exit port of the separation section and a waste stream emitted from a waste port of the separation section. The separation section includes a coiled duct and is configured to transmit through a duct entrance port a duct input air stream that is at least a portion of the input air stream and to at least partially separate the duct input air stream according to a molecular weight of gaseous components of the duct input air stream into a duct clean air stream that is at least a portion of the clean air stream and a duct waste stream that is at least a portion of the waste stream.

Abstract: A boiler loop system including a primary-secondary piping loop interface apparatus including a flow diversion device, and a drain valve, and a drain port in branches from a circumferential sidewall. In an embodiment, supply branch piping and return branch piping connect the primary-secondary piping loop interface apparatus to a boiler and provide attachment points for auxiliary plumbing equipment. In an embodiment, the boiler loop is integrated into the primary loop.

Abstract: Disclosed in this invention is a method and device for de-icing, snow melting and thawing frozen ground. The invention is based on warm moisture-laden air that can be blown over the surface to be iced or thawed or it can be introduced into an enclosed area where de-icing, ground thawing or snow melting is desired. The device consists of three components: a hot water or a steam boiler with an associated pump; a plenum for heating and humidifying air; and a delivery unit or head that brings the moisture-laden air into contact with the surface to be de-iced or thawed. In one embodiment the boiler is replaced by a direct fired burner. The delivery unit may be an air blanket with multiple perforations attached to an air duct or an inverted saucer-like delivery head likewise attached to an air duct, coming from the plenum or it can be simply an enclosed space in which is located the object to be de-iced or thawed and into which the hot moisture-laden air is conducted.

Abstract: A dishwasher having a dishwasher is provided in which an intake port cover for closing a steam intake port is mechanically operated. The dishwasher has a cavity enclosed in part by a door, and a fan motor which drives a fan installed at an upper portion of the door. During a drying operation, the fan generates a suction force to draw steam from the cavity through an intake port of the fan housing and out through an exhaust port. An intake port cover is movably installed with respect to the intake port so as to open and close the steam intake port based on an operation mode of the fan. The intake port cover has a central shaft coupled to a rotational shaft of the fan such that a driving force generated by the fan as it rotates is transferred to the intake port cover so as to selectively open and close the steam intake port. The steam intake port is open during a drying operation, and is closed during a washing and rinsing operations.

Abstract: A pressure and vacuum valve manifold system such as may be used, for example, to actuate pneumatic bladders controlling airflow in a forced air HVAC system to provide zone climate control. The valves are individually operable to connect a respective individual bladder to pressure or to vacuum. Two manifolds can be mated and commonly fed pressure and vacuum. The two manifolds can be of identical construction. One manifold chamber from each can be connected into a single large pressure manifold, and another manifold chamber from each can be connected into a single large vacuum manifold. Such connections can be made with fittings which also serve as pressure and vacuum relief valves, respectively. The valve plungers are arranged in a grid, enabling a simple X-Y two-motor servo system to actuate all the valves, one at a time.

Abstract: A heat control system designed to control individual radiators in a heating system where there is only one boiler supplying steam, or one heated fluid source such as a utility steam supply, and where there is no separate condensate return line; each radiator or riser or both may be individually controlled by devices at and external of the radiator without the need for reconstructing the heating system itself or inserting any mechanical device within the system which will block return of condensates; there is an on-off control valve between the radiator and its vent valve and controllable preferably by a room thermostat; additional fuel saving controls may include a device that is responsive to the radiator becoming heated to a desired level or internal pressure in the radiator to provide an additional control for the control valve.
