摘要： A portable electric water heater for supplying a continuous flow of hot water for outdoor home use includes an impact resistant waterproof housing having a coiled water conducting cooper tube disposed therein and wrapped with an electrical resistance heating element. A manually operated rheostat adjusts the heating current received through a power cord from a standard 110 Volt current source. The tube has a cold water inlet and a hot water outlet adapted to fit standard garden hoses and faucets. Wheels and legs support the housing and a handle facilitates movement thereof. Alternate smaller versions employ skid runners or caster wheels for portability and may have conducting tube sections positioned in a horizontal plane adjacent a respective heating element.Each embodiment utilizes an on/off toggle switch and a flow responsive pressure switch in series with the rheostat. A pop-off valve is also provided. The rheostat is arranged in circuit to permit preheating of the water by a minimum current flow when the flow switch is open due to lack of water flow through the tube.
摘要翻译：一种便携式电热水器，用于供户外使用的热水连续流动，包括具有设置在其中并被电阻加热元件包裹的卷绕水导管管的耐冲击防水壳体。手动变阻器通过电源线从标准的110 Volt电流源调节加热电流。管子有一个冷水入口和一个热水出口，适合标准的花园软管和水龙头。轮和腿支撑壳体并且手柄便于其移动。替代的较小版本采用滑动滑道或脚轮来移动，并且可以具有定位在与相应加热元件相邻的水平平面内的导管部分。每个实施例利用与变阻器串联的开/关拨动开关和流量响应压力开关。还提供了一个截止阀。当流量开关由于缺少通过管的水流而打开时，变阻器被布置在电路中以允许最小电流流动预热水。

摘要： A swim weight sleeve system for use in aquatic exercises and training applications by swimmers is disclosed. Sleeve (1) includes a rubberized sleeve material (2) containing an adjustable quantity of weights (3) and adapted to snugly fit around the forearms and/or calves of a swimmer. Sleeve (1) is adapted to stretch over the hand or foot of a swimmer and retract to substantially its original size to provide a snug fit conforming to the shape of the forearm or calf of the swimmer. Securing straps (5), provided at each end of sleeve (1), ensure a secure fit of the sleeves. A wrap-around weighted sleeve (6) and a non-weighted sleeve (10) that absorbs water to serve as weight during swimming are also disclosed.
摘要翻译：公开了一种用于游泳运动员的水上运动和训练应用的游泳重量套筒系统。套筒（1）包括含有可调节量的重量（3）的橡胶套筒材料（2），并适于紧贴地配合游泳者的前臂和/或小腿周围。袖子（1）适于在游泳者的手或脚上伸展并缩回至其原始尺寸，以提供符合游泳者的前臂或小腿形状的贴合配合。设置在套筒（1）的每个端部处的固定带（5）确保套筒的牢固配合。还公开了一种环绕加重套筒（6）和在游泳期间吸收水作为重量的非加重套筒（10）。
