A fluid flow regulator of the present invention comprises in combination a stationary hollow duct housing having a first end and a second end through which fluid flows. The device also incorporates a movable member aligned concentric with the duct having an end essentially similarly shaped and sized to the first end of the housing. The member may be spaced apart from the duct so that fluid can enter the duct housing through an opening defined by the space between the end of the member and the first end of the duct, with the movement of the member serving to change the size of opening. The movement of the member is controlled by the movement of a float located within the duct. The position of the float can be preset by the operator of the invention so that when fluid flow into the duct is at a predetermined amount the float will remain stationary, and when the fluid flow increases above such predetermined level the float will be moved in the direction of the fluid flow and when fluid flow into the duct is below said predetermined amount, the float will move the member opposite the direction of fluid flow. 1.

Electrical and electromechanical devices often require maintaining a specific temperature, or a narrow range or temperatures, during operation. An assembly regulates the temperature of a device by providing a variable thermal resistance between the device and a heatsink. The device can be mounted to a base having a high thermal resistance, the base thermally isolating the device from the heatsink. At low environmental temperatures, the base enables the device to rise to its operating temperature as a result of the device's waste heat, and with no or minimal use of a heater. As the environmental temperature increases, a working fluid, having a low thermal resistance, undergoes thermal expansion to fill a portion of a volume in the base between the device and the heat sink, lowering the thermal resistance between the device and the heatsink to maintain the device at the required operating temperature. 1. An apparatus for regulating temperature , comprising:a mount configured to accept a device on a surface thereon;a heatsink; anda base defining a well therein configured to contain a working fluid and defining a channel disposed in a thermally conductive path between the mount and the heatsink, the channel in liquid communication with the well, the well and channel being sized to enable the working fluid to expand passively from the well into the channel and contract passively from the channel into the well in continuous amounts, the amounts being a function of a temperature of the heatsink.2.
