    • A radiant heater which burns LPG fuel is provided with an improved burner assembly and an improved support assembly for mounting the heater on a propane tank. The heater includes a frame, a reflector mounted on the frame, and a burner assembly which is removably mounted within the reflector and the frame. The burner assembly includes a burner tube having an inlet end mounted within the frame and an outlet end positioned within the reflector. A generally dome-shaped screen is mounted on the outlet end of the burner tube, and a generally circular screen is attached to the dome-shaped screen substantially in alignment with the burner tube. A burner pan is mounted on the burner tube and surrounds the dome-shaped screen, and an outer screen extends across the burner pan. A thermocouple sensor and/or an igniter electrode on the frame extends through one or more openings in the burner pan. A single fastener prevents removal of the burner assembly from the frame, and when the fastener is disengaged from the burner assembly, the burner assembly can be removed and replaced. The support assembly includes a rigid support member which extends downwardly from the frame and is releasably engageable with an LPG tank. In one embodiment the support member is a fuel conduit which is connectable to a fuel valve on the LPG tank. A support bracket is adjustably mounted on the fuel conduit and is engageable with the top of the LPG tank.

    • A fuel control mechanism for a liquid fuel burner includes a fuel regulating valve which is responsive to flow of liquid fuel through a fuel feed tube for movement between a starting position and a running position. When a fuel control valve for the burner is opened, flow of liquid fuel through the fuel feed tube moves the fuel regulating valve to a starting position in which the fuel regulating valve restricts flow of fuel through a fuel inlet. Air is thereby drawn through an air inlet and mixes with the fuel. After the burner is started and liquid fuel is vaporized within the generator, flow of fuel through the fuel feed tube slows, and the fuel regulating valve falls by virtue of its weight to the running position in which the fuel regulating valve does not restrict flow of fuel through the fuel inlet. Air flow through the air inlet is thereby discontinued, and only liquid fuel flows through the fuel feed tube.
    • 用于液体燃料燃烧器的燃料控制机构包括燃料调节阀,该燃料调节阀响应于通过燃料供给管的液体燃料的流动,以在起始位置和行驶位置之间移动。 当用于燃烧器的燃料控制阀打开时,通过燃料供给管的液体燃料的流动将燃料调节阀移动到燃料调节阀通过燃料入口限制燃料流动的起始位置。 空气由此被吸入空气入口并与燃料混合。 在燃烧器开始并且液体燃料在发电机内蒸发之前,通过燃料供给管的燃料的流动减慢,并且燃料调节阀由于其重量而下降到燃料调节阀不限制流动的运行位置 燃料通过燃料入口。 因此,通过进气口的空气流动停止,只有液体燃料流过燃料供给管。

    • This invention relates to a method and apparatus for measuring the optical power of soft contact lenses having a lens holding apparatus which is mountable on known prior art lensmeter structures. The lens holding apparatus includes a basic support housing means, a lens holder assembly mounted on the basic support housing means, and a lens conditioner means connected to the basic support housing means and operably engagable with the lens holder assembly. The lens holder assembly includes a contoured lens support member having a transparent lens support surface to substantially duplicate the outer contour and size of a person's eye. The lens conditioner means includes a lens wiper assembly operable through an actuator linkage assembly to move a wiper blade member over the contoured lens support member with a soft contact lens mounted thereon to provide a wetting action on both sides of the soft contact lens to duplicate the conditions when worn on the cornea of a person's eye. This operation substantially duplicates the condition of the soft contact lens as being worn on the cornea of a person's eye. The method of this invention relates to optical power measurement with the use of a lens support member being (1) cleansing; (2) wetting; (3) wiping; (4) measuring the soft contact lens; and (5) periodically rewetting and operating the device as required.

    • A unitary airflow diffuser for use with a forced-air space heater has a plurality of spurs radially extending from a hub. The spurs include one or more vanes for deflecting the airflow generated by fan blades within the space heater. A nozzle assembly is secured through an aperture in the hub of the diffuser for supplying fuel within a combustion chamber. Brackets can be provided for securing an igniter and a sensor to the airflow diffuser. Mounting tabs are provided on each vane to secure the airflow diffuser to a mounting plate disposed at the input of the combustion chamber. The nozzle ejects the fuel through a central aperture in the mounting plate into the combustion chamber. The mounting plate can have secondary apertures through which air can be diverted, and vanes can be provided on the mounting plates to direct air through the secondary apertures. The deflected air ensures that the fuel swirls around the nozzle and igniter and also serves as auxiliary combustion air with the result that a uniform, clean burning flame is realized.
    • 与强制空气空间加热器一起使用的单一气流扩散器具有从毂径向延伸的多个刺。 马刺包括用于偏转由空间加热器内的风扇叶片产生的气流的一个或多个叶片。 喷嘴组件通过扩散器的毂中的孔固定,以在燃烧室内供应燃料。 可以提供支架,用于将点火器和传感器固定到气流扩散器。 安装翼片设置在每个叶片上,以将气流扩散器固定到设置在燃烧室输入端的安装板。 喷嘴将燃料通过安装板中的中心孔喷射到燃烧室中。 安装板可以具有二次孔,通过该孔可以转动空气,并且可以在安装板上设置叶片以引导空气通过次级孔。 偏转的空气确保燃料在喷嘴和点火器周围旋转,并且还用作辅助燃烧空气,结果是实现均匀,清洁的燃烧火焰。
