Abstract: A modular support structure for a control room work station is disclosed which is capable of being used to support top surfaces of different shapes. The support structure includes a plurality of adjustable posts wherein each post comprises two elongated rectangular post flanges, each having a top edge for supporting the top surface, a bottom edge, an elongated outer edge and an elongated articulating edge opposing said outer edge, and hinge means for articulating said two rectangular post flanges with each other along said articulating edges. The hinged posts permit the attachment of panels at a variety of angles to accommodate the shape of the top surface. Also provided is a control room work station having the modular support structure of the present invention.

Abstract: A filter device, usable as a self-contained or freestanding unit or in association with an associated air treatment installation such as a furnace or air conditioner.A preferred embodiment has a housing in which is supported a parallel-arranged plurality of filter bags folded over to achieve high filter area in comparison to the size of the housing; and ductwork leads the incoming air to the filter bags, which are formed of HEPA paper for screening out even extremely small particles.The housing is hermetically sealed; and there is provided a blower for drawing in air, and causing it to pass through the filter bag system and into the interior of the housing, and then out the housing outlet for entrance to the associated air treatment installation.

Abstract: A chemical-mixing and dispensing apparatus for providing a volume of a chemical mixture to a dispensing location includes a suitably connected and monitored water main flow coupled to one inlet of a Tee fitting, a fixed-volume container having therein a liquid detergent concentrate, the container being coupled to the other inlet of the Tee fitting. The outlet of the Tee fitting is placed in flow communication with a chemical mixture holding tank along one branch and with a control tank along another branch. The chemical mixture holding tank has an output line which is monitored by an electrically timed solenoid valve for controlling the dispensing of the contents of the holding tank to a spray nozzle. Flow to the control tank is monitored by a pressure regulator such that the pressure ceiling within the control tank remains at a level which is below the pressure ceiling of the holding tank.

Abstract: An air treatment apparatus for removing particulate matter and contaminants from a flow stream of air includes an air inlet chamber coupled to an air inlet duct and two spaced-apart air flow chambers communicating with the air inlet chamber at a first end and with an outlet duct at their opposite end. Disposed within each air flow chamber is a continuous belt filter arranged over a plurality of drive rollers. There are two rows of drive rollers spaced apart and arranged so as to position the filter throughout virtually the entire inner cavity of each air flow chamber. Each air flow chamber includes an opening with a cleaning subsystem positioned adjacent thereto. The cleaning subsystem includes a spray nozzle disposed above the opening and an air tube positioned interior and the filter passes across and around the air tube as it passes past the opening.

Abstract: An air-cleaning, heat-exchange apparatus includes a main housing portion connected by means of an air inlet fan to the kitchen exhaust stack of a restaurant. The apparatus includes a plurality of heat exchangers through which a heat-absorptive fluid is circulated, simultaneously, by means of a suitable fluid pump. These heat exchangers absorb heat from the hot exhaust gas, out of the exhaust stack of the restaurant, which flows over and through these heat exchangers and transfers this heat to the circulating fluid which communicates with remote heat exchangers. These remote heat exchangers further transfer this heat to a stream of air, such as that from a cold-air return duct for supplementing the conventional heating system of the restaurant. Due to the fact that such hot exhaust gas is heavily grease laden, grease will be deposited on virtually all internal surfaces of the apparatus which this exhaust gas contacts.

Abstract: An air-cleaning, heat-exchange apparatus includes a main housing portion connected by means of an air inlet fan to the kitchen exhaust stack of a restaurant. The apparatus includes an in-line series of three heat exchangers through which a heat-absorptive fluid is circulated, simultaneously, by means of a suitable fluid pump. These heat exchangers remove exhaust gas heat and further transfer this heat to a stream of air, such as that from a cold-air return duct. Due to the fact that the hot exhaust gas is heavily grease laden, grease will be deposited on virtually all internal surfaces of the apparatus which this exhaust gas contacts. The apparatus includes means for spraying exhaust gas contacted internal surfaces, as well as the hot exhaust gas itself, with a detergent solution in which the grease is soluble, thereby removing grease buildup from these internal surfaces.
