摘要： A light sensitive dimmer switch circuit for controlling the illumination level of a light as a function of the ambient illumination level surrounding the dimmer switch circuit by selectively controlling an AC power signal provided to the light includes a photocell and a phase control circuit. The photocell is responsive to the ambient illumination level and has a conduction state associated therewith. The conduction state changes, in response to the ambient illumination level, such that the photocell effectively exhibits either a substantially open circuit or a substantially short circuit. The phase control circuit selectively varies a conduction phase angle associated with the AC power signal which correspondingly causes a variation in the illumination level of the light. The phase control circuit, in response to the photocell, selectively varies such conduction phase angle and thus the illumination level associated with the light when the photocell exhibits an open circuit and, conversely, prohibits the AC power signal from being provided to the light when the photocell exhibits a short circuit. Preferably, the phase control circuit permits the light to illuminate approximately at a full illumination level while the photocell exhibits a short circuit. Thus, the light sensitive dimmer switch circuit controls the light such that a user may operate the same in either an off region, a dimming region or a full illumination region.
摘要翻译：用于通过选择性地控制提供给光的AC电力信号来控制作为围绕调光开关电路的环境照明水平的光的照明水平的光敏调光器开关电路包括光电管和相位控制电路。光电池响应于环境照明水平并且具有与其相关联的导通状态。导通状态响应于环境照明水平而变化，使得光电池有效地表现出基本上开路或基本上短路。相位控制电路选择性地改变与AC功率信号相关联的导通相位角，这相应地导致光的照明水平的变化。响应于光电池，相位控制电路选择性地改变这种导电相位角，并因此选择性地改变当光电池呈现开路时与光相关联的照明水平，并且相反地，当禁止将光功率信号提供给光时，光电管表现出短路。优选地，相位控制电路允许光在全光照水平下照亮，同时光电池呈现短路。因此，光敏调光开关电路控制光，使得用户可以在关闭区域，调光区域或完全照明区域中操作它们。

摘要： A lamp with improved safety features to avoid fire and burn hazards. The lamp includes an electrical circuit having a thermostat connected in series with the bulb of the lamp. The thermostat is mounted in close proximity to the lamp's bulb and, upon the ambient air temperature in the vicinity of the thermostat reaching a predetermined temperature, the thermostat effectively opens the electrical circuit, shutting the lamp off. Once power is turned off for a period of time, the thermostat resets and the lamp may be operated again. A protective guard is positioned over at least a portion of the bulb of the lamp to prevent accidental burning.

摘要： A support particularly adapted to support an electric fan is provided. The support has a cam action quick release mechanism which is movable between locked and free positions. When the release mechanism is in the free position the fan can be easily rotated to a desired degree of tilt about a horizontal axis. When the release mechanism is in the locked position rotation of the fan is prevented. The support also includes tilt limiting mechanisms which sets a predetermined forward and backward limitation on fan rotation.

摘要： A tiltable fan assembly adapted to exhaust air at a variety of angular orientations. In a preferred embodiment, the tiltable fan assembly includes a generally flat base member adapted to rest on a table top or similar surface. The base member is shaped to include a pair of horizontally-extending, cylindrically-shaped sleeves. The fan assembly also includes a pair of mounting posts, each mounting post being angularly adjustably mounted about its longitudinal axis within its respective sleeves and being appropriately sized to extend out through both ends of its respective sleeve. A rotary switch is angularly adjustably mounted on the outer end of one of the mounting posts, and a cap is fixedly mounted on the outer end of the other of the mounting posts. A pair of gaskets are fitted onto the inner ends of the mounting posts. The fan assembly further includes a fan unit and a neck assembly, the neck assembly being used to couple the fan unit to the angularly adjustable mounting posts. The neck assembly preferably includes a pair of neck elements, the first neck element being integrally formed with the fan unit and having a semi-cylindrical bottom portion. The second neck element is semi-cylindrical in shape and fits together with the bottom portion of the first neck element over the inner ends of the pair of mounting posts. The pair of gaskets on the mounting posts serve to mechanically couple the mounting posts to the neck elements.
