    • Improved gas-fired radiant heater has porous refractory panel mounted by its edges on a support to define a gaseous combustion mixture plenum from which the mixture flows through the panel to burn at its outer face, and a conduit for non-combustible gas extends along the margin of the panel and discharges the non-combustible gas through the panel all along its margin to keep the combustion mixture from escaping through the panel edges where burning can damage the panel. No further sealing of the panel margin is needed, but the sealing is effected with less of the non-combustible gas if the panel edges are compressed so as to reduce their thickness about 10%. One or more of the margins of a rectangular panel can be arranged as a depending flange with its mounting at least partially recessed so that two or more panels can be juxtaposed at such margins to form an effectively continuous radiating surface of relatively large size. The air seal construction also makes such heaters very practical for firing house heating furnaces.
    • 改进的燃气辐射加热器具有通过其边缘安装在支撑件上的多孔耐火板,以限定气体燃烧混合物气室,混合物从该混合气室流过面板,在其外表面燃烧,并且用于不可燃气体的导管沿着 面板边缘并沿着其边缘排出不可燃气体通过面板,以防止燃烧混合物通过面板边缘逸出,因为燃烧会损坏面板。 不需要进一步密封面板边缘,但是如果面板边缘被压缩以便将其厚度减小约10%,则密封是用更少的不可燃气体来实现的。 矩形面板的一个或多个边缘可以布置为悬垂法兰,其安装件至少部分地凹入,使得两个或更多个镶板可以在这样的边缘处并列形成相对大尺寸的有效连续的辐射表面。 空气密封结构也使这种加热器非常实用于烧制炉子加热炉。

    • An animal behavioral control device having a microphone responsive to both ambient noise around the animal and to emitted sound from the animal such as barking for extending an electrical signal corresponding only to the emitted sound and a vibrating apparatus being activated in the presence of the electrical signal for vibrating the area of the animal's neck nearest the vocal cords to cause the animal to be distracted either in a first range of preferred vibration in a first embodiment of the invention, or to swallow in a second range of preferred vibration in a second embodiment of the invention thereby substantially preventing the animal from emitting the barking sound.
    • 一种具有麦克风的动物行为控制装置,其具有响应于动物周围的环境噪声和来自动物的发出的声音,例如吠叫,用于扩展仅对应于发出的声音的电信号,以及在存在电信号的情况下激活振动装置 用于振动最靠近声带的动物颈部的区域,以在本发明的第一实施例中使动物在优选振动的第一范围内分散,或者在第二实施例的第二实施例中在第二优选振动范围内吞咽 因此本发明基本上防止动物发出吠叫声。
