摘要： A magnet piece and armature are arranged around a circuit breaker load strap having a bimetal strip attached thereto. The magnet piece is formed in a U-shaped configuration and is attached to the load strap. A corresponding U-shaped armature is pivotally mounted to the magnet piece in a partially overlapping relation. The U-shape armature presents a larger magnet pole surface to the magnet piece for enhanced magnetic interaction.

摘要： A selectable rating plug allows a standard molded case circuit breaker design to be used over a wide range of ampere ratings. The rating plug is used to control the thermal load on the thermally responsive trip element within the breaker. Movement of the thermally responsive element articulates the breaker trip mechanism in response to predetermined overload conditions to interrupt circuit current.

摘要： The present invention provides a rear gun rest that can be attached to a stock of a firearm in a permanent fashion. The rear gun rest remains on the firearm with minimal interference with the use of the firearm. The rear gun rest includes a main tube pivotally connected to said stock. The main tube includes a pivot pin as part of the main tube, a retaining pin as part of the main tube and at least one tension spring connected between said pivot pin and said retaining pin. The pivot pin allows the pivoting of the main tube. The tension spring aids in retaining the main tube in a desired position. The rear gun rest also includes an extension tube and a fine adjustment rod for adjusting the height of the stock. The extension tube is extendible from the main tube. The fine adjustment rod is extendible from the extension tube.
摘要翻译：本发明提供一种可以永久性地附接到枪支的库存的后枪支架。后枪支持在枪支上，对枪支的使用几乎没有任何干扰。后枪支架包括枢转地连接到所述坯料的主管。主管包括作为主管的一部分的枢轴销，作为主管的一部分的保持销和连接在所述枢转销和所述保持销之间的至少一个张力弹簧。枢轴销允许主管的枢转。拉伸弹簧有助于将主管保持在期望的位置。后枪支架还包括延伸管和用于调节坯料高度的微调杆。延伸管可从主管延伸。微调杆可从延长管延伸。

摘要： Sampling equipment is provided for sensing and controlling the settling rate of a flocculated slurry suspension in a settling tank, the sampling equipment comprises a metering device (23) including a vertical settling chamber for repeatedly taking a sample of the suspension from the settling tank. Means (33, 35, 19) are provided for temporarily retaining the height of the sample at a preselected level during a settling period and detector means (40, 41, 42) are provided for detecting when a boundary level defined by the settling solids reaches a further preselected level. Timer means determine the actual settling period elapsing between the start of the settling period and the time when the boundary level has reached the further preselected level.
摘要翻译：提供采样设备用于感测和控制沉降池中絮凝浆料悬浮液的沉降速率，采样设备包括计量装置（23），其包括用于反复从沉淀池中取样悬浮液的垂直沉降室。提供装置（33,35,19），用于在沉降期间临时将样品的高度保持在预选的水平，并且提供检测装置（40,41,42）以检测何时由沉降固体达到的边界水平达到进一步预选级别。定时器意味着确定在建立周期开始和边界电平达到进一步预选电平的时间之间经过的实际建立时间。
