摘要： A temperature-controlled environmental chamber includes a resistance heater controlled by a solid state relay and a refrigeration unit including an electronically controlled suction throttling valve connected in the refrigerant line between the evaporator and the inlet of the compressor. A temperature controller senses the temperature in the chamber and compares it to a set point temperature and outputs a pulse-width modulated control signal indicative of the difference between the two temperatures. The control signal directly controls the heater relay for substantially continuous variation between minimum and maximum heating conditions. The control signal is converted to an analog signal for controlling the throttling valve of the refrigeration unit for substantially continuous variation between maximum and minimum cooling conditions, so that the amount of cooling provided is inversely proportional to the amount of heating provided. A hot gas bypass is provided for maintaining a minimum input pressure on the condenser and a refrigerant bypass is provided to maintain the input temperature of the compressor below a predetermined maximum.
摘要翻译：温度控制环境室包括由固态继电器控制的电阻加热器和包括连接在蒸发器和压缩机入口之间的制冷剂管线中的电子控制的吸入节流阀的制冷单元。温度控制器感测室中的温度并将其与设定点温度进行比较，并输出指示两个温度之间的差的脉宽调制控制信号。控制信号直接控制加热器继电器，用于在最小和最大加热条件之间实质上连续的变化。控制信号被转换为用于控制制冷单元的节流阀的模拟信号，用于在最大和最小冷却条件之间实质上连续的变化，使得所提供的冷却量与所提供的加热量成反比。提供热气旁通以保持冷凝器上的最小输入压力，并且提供制冷剂旁路以将压缩机的输入温度保持在预定最大值以下。

摘要： An implement includes first and second elongated legs that are joined by a first hinge between respective one ends thereof to permit those legs to be folded toward and away from one another. The legs are mutually shaped to define a cavity within a handle when folded together about the hinge. Third and fourth elongated legs are each of a size to be nested within the portion of the cavity defined by a respective one of the first and second legs. A second hinge couples one end of the third leg to the other end of the first leg. A third hinge couples one end of the fourth leg to the other end of the second leg. Finally, a fourth hinge couples together the other ends of the third and fourth legs. The legs individually have respective different lengths to define a toggle movement of the third and fourth legs between a first stable position concealed within the cavity of the handle and a second position in which they project generally co-linearly away from the cavity and the first and second legs when the latter are folded together. Defined on at least one of the third and fourth legs and for performing a task, when those first and fourth legs project away from the cavity, is a working implement.

摘要： A multiple-compartment container is formed from an elongated sleeve of flexible material. Opposing end portions of the sleeve are respectively sealed together. A third seal of the walls of the sleeve, at a location spaced between those end portions, defines first and second hollow compartments respectively on each side of that third seal. The third seal is effected by a twisting of the sleeve about its longitudinal axis. There is illustrated a still further and preferred fourth seal at a location spaced between the third seal and one of the end portions so as to define a still further hollow compartment, and that additional seal also is effected by a twisting of the sleeve.
摘要翻译：多层容器由柔性材料的细长套筒形成。套筒的相对端部分别密封在一起。在这些端部间隔开的位置处的套筒的壁的第三密封件分别在该第三密封件的每一侧上限定第一和第二中空隔室。第三密封件通过套筒围绕其纵向轴线的扭转来实现。在第三密封件和一个端部之间隔开的位置处示出了又一个又优选的第四密封件，以便限定另外一个中空隔室，并且另外的密封件也可以通过套筒的扭转来实现。
