Abstract: A snap acting heat motor operated gas valve having a valve member carried by a spring blade that is secured to one end of an electrically heated control bimetal strip. Magnetic means associated with the spring blade normally bias the valve member to a closed position to permit opening of the valve member upon a predetermined heating of the control bimetal member and to effect a snap action opening and closing of the valve member. An ambient temperature compensating bimetal member has a cantilever portion in spaced relation to the control bimetal strip and acting on the spring blade to offset the effects of ambient temperature changes upon the control bimetal member.

Abstract: A space heating unit comprises a pump forcing a working fluid such as a heavy synthetic oil through a shearing means to effect working and consequent heating thereof. The thus heated working fluid is passed through a heat exchanger to warm air circulating therethrough. The space heater is designed to operate cyclically with the heat exchanger and thus the working fluid being maintained at a minimum operating temperature by means of a heat store in heat exchange contract with at least a portion of the heat exchanger. The heat store contains for example a eutectic mixture of salts which undergo a phase change at about the minimum operating temperature desired for the working fluid. The heat store removes and stores heat energy from the unit when it is operating and returns its heat energy to the unit when the unit is in its at-rest mode, thereby maintaining the temperature of the unit and of the working fluid for the next cycle.

The liquid released into the quiet zone in the slot forms drops characteristic of laminar flow. Those drops then flow from the slot at the trailing edge of the streamlined body and discharge into the slipstream for free distribution.

Abstract: An upper U-shaped slide member and a lower U-shaped slide member are slidably coupled to form a generally rectangular framework. For storage, the upper and lower slide members are moved toward each other to reduce the size of the generally rectangular framework. A U-shaped rotating support member is pivotally coupled to said U-shaped slide members.

The linkages also move the rotating support member to a supporting position when the lower slide member is itself extended to a supporting position. Wheels coupled to the rotating support member and/or the lower slide member provide ease of movement of the frame. Extending the upper slide member provides a handle whereby the frame may be maneuvered readily.

Movement of the door toward partially closed position engages the cam lever with the leading edge of a body mounted striker plate to move the cam lever and slide bolt to their retracted positions against the force of the spring. Final closing of the door disengages the cam lever from the leading edge of the striker plate. The spring returns the cam lever and slide bolt to extended position to engage the slide bolt with another edge of the plate and retain the door in closed position.
