摘要： A radiator cap loosening and removal tool includes a generally U-shaped handle pivotally attached to a base, which is in turn fastened to the depending skirt portion of a radiator cap by self-tapping sheet metal screws. An alternative embodiment comprises a U-shaped handle whose legs embrace the skirt of the radiator cap and are pivotally fastened thereto by screws or rivets. Another alternative embodiment comprise a crossbar fastened to the skirt of a radiator cap by threaded fasteners, which serve as pivots for a U-shaped handle.

摘要： Controlling a switch or valve at a distance is achieved by a support member having a movable portion, with the moveable portion including an elongate member, and a drive mechanism in communication with the moveable portion. A motor, hand crank, or other force transmission apparatus acts to move the drive mechanism and thus the movable portion and elongate member such that a valve or switch is actuated at a distance from a user.

摘要： A manually operated refrigeration apparatus includes a refrigerant compressor which is operated solely by manual or pedal power, and which requires no other automated or external power or energy source. The apparatus generally comprises a cylindrical refrigerant compressor, with the refrigerant being compressed by a piston driven by a coil spring within the cylinder. The spring is in turn compressed by an external lever or pedal operated linkage, with compression of the refrigerant being initiated when the spring compression is released. The refrigerant then passes through an expansion valve, whereby the refrigerant pressure drops to cause the fluid to evaporate and drop in temperature, as in powered refrigeration devices. The apparatus is connected to an insulated cooler chest or the like, with the chest including refrigerant lines within the walls and/or floor. The present refrigeration apparatus is capable of indefinitely maintaining relatively low temperatures within the cooler, thereby preserving food or other articles for relatively long periods of time while away from external power sources. The compression may be pumped up periodically, with the internal spring producing refrigerant flow through the system for a period of time before requiring additional actuation. Once the cooler temperature has reached the desired level, the insulation provides substantial maintenance of the temperature for some period of time before additional operation of the apparatus is required.
摘要翻译： 手动制冷装置包括仅由手动或踏板动力操作并且不需要其它自动或外部动力或能源的制冷剂压缩机。 该装置通常包括圆柱形制冷剂压缩机，其中制冷剂由在气缸内由螺旋弹簧驱动的活塞压缩。 弹簧又通过外部杠杆或踏板操作的联动装置压缩，当释放弹簧压缩时制冷剂的压缩被启动。 然后，制冷剂通过膨胀阀，由此制冷剂压力下降，导致流体蒸发并降低温度，如在动力制冷装置中。 该设备连接到绝热的冷却器柜等，胸部包括在墙壁和/或地板内的制冷剂管线。 本制冷装置能够在冷却器内无限期地维持相对较低的温度，从而在远离外部电源的同时保存食物或其它制品相当长的时间段。 可以周期性地泵送压缩，其中内部弹簧在需要额外的致动之前使制冷剂流过系统一段时间。 一旦冷却器温度达到所需的水平，绝缘体在需要设备的额外操作之前，可以对温度进行一段时间的实质维护。

摘要： A casing has a plurality of upright panel-type compartments disposed in spaced relation for allowing flue gases and smoke to circulate therebetween. A blower circulates room air through the compartments and back into the room. A cross shaft is mounted in the casing adjacent the top thereof and extends across the spaces between the compartments. Levers are integrated with the cross shaft and support chains in suspended relation between the compartments. The shaft has a projecting handle which when operated is used to oscillate the chains to knock off soot and creosote from the exterior surfaces of walls of the compartments.

摘要： A firebox for a stove is defined by top, bottom, side and end walls and employs a loading door in one of the end walls. A main draft opening associated with an adjustable damper control is provided adjacent the lower portion of the firebox and an auxiliary draft opening associated with an adjustable damper control is provided adjacent the top portion of the firebox. In a preferred arrangement the main and auxiliary draft openings are disposed adjacent one of the end walls. Also, in a preferred arrangement, the auxiliary draft opening is disposed upwardly within at least the upper one-third of the firebox. The particular structure of the stove facilitates good combustion for heating but at the same time provides an efficient shut-down condition that will maintain a small holding fire without causing creosote to build up in the flue. The main draft opening is associated with a movable door arranged to be forced open in the event of pressure being developed in the firebox.

摘要： A rotary control valve for an expansion fluid driven engine has a body with inlet and outlet ports and a distribution port communicating with an engine cylinder. A shaft in the body has first and second discs thereon and rotates in synchronization with reciprocation of the engine piston. The first disc has a pressure fluid passage therethrough and the second disc has an exhaust fluid passage therethrough. Sealing pistons in the body urge against the discs and have passages therethrough respectively connecting the pressure fluid passage with the inlet and distribution ports and the exhaust fluid passage with the distribution and outlet ports. The rotation of the discs alternately permits and stops flow of fluid to and from the cylinder.

摘要： A remote control system for vertically racking circuit breakers into and out of electrical switchgear cells includes a lever mechanism for coupling the drive shaft of a portable drive motor to the driven shaft of a circuit-breaker racking mechanism and a latching solenoid for locking the coupled shafts together. A power-transfer panel is provided in the cell and is connected for transferring control of the drive motor, the latching solenoid and the circuit breaker to a remote control and status indicating device that is located externally of the cell cabinet. An inclinometer is mounted on the circuit breaker for producing an alarm signal and interrupting operation of the circuit-breaker elevating mechanism upon detecting an excessive amount of tilting in the normally level attitude of the circuit breaker.
