摘要： A photo detecting flow sensing bending beam fluid flow switch and flow meter system having blocking targets that selectively block the optical path from an emission source to a photodetector. The device provides a system which is very sensitive to fluid flow in a pipe, container or duct by providing a shaped flexible flow sensitive bending beam having a blocking target which is bent so that the portion of the blocking target is displaced between the emission source and a photodetector. The shaped blocking target is configured to either interrupt or permit the transmission of emission from the emitter to the photodetector. The presence or absence of the source represents the presence or absence of a fluid flow rate above or below a selected value thus, performing a fluid flow switch function. By modifying the blocking target to provide a reflective control from an emission to a photo detector or an absorption of the emission by a target varying in opacity, the relative light output is continuously modulated to produce a voltage output directly proportional to the rate of fluid flow past the target on a flow sensitive bending beam. In an optional embodiment, flow sensitivity is improved by adding vortex shedding enhancements to the flow sensitive bending beam. This combination of functional elements can provide an analog fluid flow meter transducer for flow metering, totalizing in a flow monitoring system having single or multiple flow switching set points.

摘要： An improved plastic bag sealing apparatus comprised of an improved heater formed of a heating wire embedded in a silicon rubber material. The heater is shaped to conform to the flat planar surface of a T-bar shaped heating element, and clamped in place with insulators to provide maximum transfer of heat to the heating edge formed by the web portion of the T-bar. The containment of heat and transfer of maximum heat to the T-bar permits a substantial improvement in thermal efficiency and a substantial reduction of power consumption. The heating edge of the T-bar is covered with an easily replaceable heating channel coated with a non-stick, heat resistant material such as polytetraflouroethylene (TEFLON).

摘要： A fluid flow monitoring system comprised of a permanent magnet mounted on a bendable spring blade that provide an output from a Hall effect transducer as the permanent magnet is deflected toward the transducer. The permanent magnet can be mounted to directly approach the Hall effect transducer or can also be mounted to approach the transducer by a sideways bypass direction. Both the direct motion and sideways bypass direction allows the use of a variety of sizes and shapes of magnets that allow the magnetic field intensity to be modified in any way desired. Various magnet shapes such as cylinders, rectangles, pyramids, triangles or compound magnets from these shapes may be used. The output signal of the transducer is processed through a smoothing filter and circuits that produce a linear output or a stepped digital output. The system preferably uses a resistance/capacitance filter to provide a different time constant for an increasing flow or a decreasing flow. The output can be used as a flow switching circuit or as a flow meter, or as a flow quantity totalizer.

摘要： A small portable steam generating system comprised of an elongate cylindrical cylinder having a turbulent baffle circulation system. The steam generator includes a plurality of baffles, having alternating ports spaced along the length of the cylinder. The baffles have ports offset at 180° respectively to each other to provide turbulent flow that speeds up and slows down as it passes through the ports. The series of baffles in the elongate cylinder are mounted around a centrally located heater. The surfaces and ports in the baffles, positioned along the elongate cylinder and heater body, form a diffused turbulent flow of variable length and time as it passes from an input to an output. The steam generating system described herein is fitted with a steam water droplet separation system plus a high pressure steam superheater fitted to an exit tube and a non-conductive high temperature tube for transporting super-heated steam to a surface cleaning applicator. The system uses a low flow capacity, high pressure pump to inject feed water into the steam generator. The system is controlled by a computer processing system which monitors water level, steam temperature, and pressure.

The heater is shaped to conform to the flat planar surface of a T-bar shaped heating element, and clamped in place with insulators to provide maximum transfer of heat to a heating edge formed by the web portion of the T-bar.
