摘要： An improved water heater for use in spas, hot tubs, pools, hydrotherapy pools, bath tubs, and similar bodies of water used indoors, outdoors, or both indoors and outdoors are used for both therapeutic and recreational purposes. The water heater uses heating element technology know as thick film on substrate comprising resistive elements bonded to the outer dry surface of a pipe to heat the pipe which in turn heats the water flowing therethrough. The heater is highly efficient due to the direct contact of the wet heating surface with the water and provides a smooth seamless inner heating surface by eliminating the need to pass electrical leads into the wet region of the heater. This virtually eliminates the risk of leaks in the water heater due to bulkhead fittings. The invention further eliminates the need for a heating element to be contained in the inner wet region of a spa heater, thereby reducing the risk of corrosion. The water heater is used in combination with an electronic controller having a microprocessor to control and regulate the operation of the water heater. The water heater can be used with electrical, electro-mechanical, and mechanical control systems for spas and can be retrofitted into existing spa applications.
摘要翻译：用于室内，户外或室内或室外的用于温泉，热水浴池，游泳池，水疗池，浴缸和类似体内的改进的热水器用于治疗和娱乐目的。热水器使用加热元件技术，称为基板上的厚膜，包括结合到管的外部干燥表面的电阻元件，以加热管道，其又加热流过其中的水。由于湿加热表面与水的直接接触，加热器是高效的，并且通过消除将电引线通入加热器的湿区域的需要而提供光滑的无缝内部加热表面。这实际上消除了由于舱壁配件导致的热水器泄漏的风险。本发明进一步消除了在温暖加热器的内部湿区域中容纳加热元件的需要，从而降低了腐蚀的风险。热水器与具有微处理器的电子控制器组合使用以控制和调节热水器的操作。热水器可以与电气，机电和机械控制系统一起用于水疗中心，并可以升级到现有的水疗应用。

摘要： A system for metering and dispensing single and plural component liquids and solids as described herein. The dispensing system has a microprocessor-based control system and progressive cavity pumps which provide a very accurate control of component ratios, shot sizes, flow rates and dispense durations. The system has numerous feedback components for accurately controlling the pressure, flow rates, fluid levels and amounts of fluids dispensed. Where a valved nozzle is used, the pressure in the flow system is used to control the pumps rather than the valve. Such a system may be used as a sprayer with compressed air added. Drum rams are associated with the supply drums and the progressive cavity pumps may be placed on the drum ram. Maintenance of a steady state in the system is accomplished with back and forth movement of the pump, with compensation for pressure changes. Absolute rotational position of the pump can be monitored when a set pressure is maintained, to diagnose system conditions. A high flow system uses ball valves and a releasably coupled manifold. A mold charging system uses pressure to control the pumps which are cycled on and off to avoid overpressurizing the mold. The rate of pressure increase is used to control the rate of flow from the pumps as the mold approaches completion of the charge, again to avoid overpressurizing the mold. A signal controlled by a timer can indicate elapsed time as a warning that material within the mixer conduit is hardening to a condition such that flow cannot be reinitiated.
摘要翻译：用于计量和分配如本文所述的单组分和多组分液体和固体的系统。分配系统具有基于微处理器的控制系统和渐进腔泵，其提供组件比率，喷射尺寸，流速和分配持续时间的非常准确的控制。该系统具有许多反馈组件，用于精确控制分配的流体的压力，流速，流体水平和量。在使用带阀的喷嘴的情况下，流量系统中的压力用于控制泵而不是阀。这种系统可以用作喷雾器，其中加入了压缩空气。鼓筒与供应滚筒相关联，并且渐进式泵可以放置在滚筒冲头上。在系统中维持稳定状态是通过泵的前后运动实现的，并补偿压力变化。当保持设定压力时，可以监测泵的绝对旋转位置，以诊断系统状况。高流量系统使用球阀和可释放地联接的歧管。模具充电系统使用压力来控制循环开启和关闭的泵，以避免模具过压。当模具接近充电完成时，压力增加率用于控制来自泵的流量，再次避免过度加压模具。由定时器控制的信号可以指示经过时间作为警告，即混合器管道内的材料硬化到不能重新流动的状态。

摘要： A dispensing system including a housing with an interior bulkhead and four progressive cavity pumps mounted within the housing on one side of the bulkhead. The pumps are mounted with the bores in vertical orientation. Gear boxes including bevel gears coupling the vertically mounted pumps with horizontally mounted motors located on the other side of the interior bulkhead. A dispensing head is located above the housing with outlet passages extending from the motors to the dispensing head defining a path to the dispensing head which is continuously upward. The dispensing head includes valves driven by a pneumatic cylinder. A solenoid controls flow of pressurized air to the pneumatic cylinder from a position adjacent the dispensing head on the boom supporting both.

The dispensing system has a microprocessor-based control system and volumetrically efficient non-reciprocating pumps which provide a very accurate control of component ratios, shot sizes, flow rates and dispense durations. The dispensing system maintains constant pressure between the output of the pump and the dispense head. The progressive cavity pump is formed from individual, interlocking pressure sections, each of which has a double helix bore. A rotor is inserted into the double helix bore with an interference fit. The dispense head has no dynamic fluid sealing surfaces and instead uses bellows as a sealing mechanism. The dispensing system includes a simple, easy to use calibration procedure and a weight scale.

A dispense head for a plural pump dispensing system using sealed bellows with rods extending therethrough associated with an actuator. The sealed bellows attach at one end to the body of the dispense head and at the other to the rods. The rods extend into a chamber and have a sealing end selectively engaging the exits from the chamber. The dispense head may further incorporate an actuator controlling the rods, a controller controlling the pumps and the actuator to close down the system simultaneously and the pumps themselves. A static mixer may be used with the exits. The system also has numerous feedback components for accurately controlling the pressure, flow rates, fluid levels and amounts of fluids dispensed.
