Abstract: The disclosure relates to an enclosed cup like drinking receptacle having a cover provided with a drinking opening therein which is disposed near the peripheral portion of the cover; the drinking opening being controlled by a liquid dispensing valve and a pneumatic pressure relief valve, both carried by a common manual actuator such that both valves are moved in unison and the dispensing valve being moveable relative to its seat a short distance without breaking its seal relative to said seat and to provide for sufficient movement of the pressure relief or vent valve to vent pneumatic pressure from the interior of said receptacle and cover so as to prevent unwarrented flow of hot beverages or the like through said dispensing valve and said drinking opening and thereby allowing a person to drink through said drinking opening with the normal flow of a hot beverage or other beverage therethrough.

Abstract: A back draft damper for exhaust fans and hoods such as those used in kitchens or bathrooms; the damper comprising a stationary valve plate having a pair of openings and an elongate slot between said openings with a pair of flapper valve plates having curved edge portions extending through said slot and forming pivotal mounting for said flapper valve plates on said stationary valve plate; said flapper valve plates having extremities overlapping said openings in said stationary valve plate; the flapper valve plates being openable by air under pressure and closeable by gravity, and being on an upper surface of said stationary valve plate.

Abstract: The disclosure relates to a multi cylinder four cycle gasoline engine having substantially conventional intake and exhaust valves in the head ends of the cylinders thereof and having side ports in the cylinders; said side ports in spaced relation to the head ends of the cylinders; a fuel mixture delivery means communicating with said ports; an auxilliary intake manifold which is enclosed; said auxilliary intake manifold communicating only with said intake valves at the head ends of the cylinders; second intake valves disposed to control and time the flow of fuel mixture into said cylinders through said ports.

Abstract: The disclosure relates to a solar radiation converting method and means whereby the addition of a halogen within a hermetically sealed spaced receives and converts solar or synthetic radiant spectra into heat energy; its principal advantage being the conversion of the visible portion of the light spectra into additional heat.

Abstract: The disclosure relates to a tooling set up and subplate means for machine tools wherein a subplate is provided with intersecting rows of openings; said rows precisely intersecting each other at right angles and some of said openings having precision locating bushings therein and others of said fixture openings being internally screwthreaded fixture openings. The locating openings are in rows adapted to be precisely aligned with the two axes of movement of the machine tool table and hold down means adapted to secure said subplate on the machine tool table and tooling members having fixture receiving openings and locating openings adapted to coincide with the respective openings in said subplate so as to precisely align tooling with the movement axes of a machine tool and to thereby alleviate the time usually devoted to the alignment of a piece of work on a machine tool with respect to its directions of movement.

Abstract: The disclosure relates to an air conditioning system employing a heat pump in combination with facilities for thermal storage, evaporative cooling and solar heat collection, as well as solar heat radiation; the heat pump having an indoor heat exchanger and an outdoor heat exchanger and a third heat exchanger in series with the outdoor heat exchanger; the third heat exchanger being disposed to receive heat or cool air so as to augment operation of the heat pump during critical ambient conditions so as to improve the relative efficiency of the heat pump when operating under the aforementioned critical conditions.
