Abstract: A fireplace has an imperforate dished fire-pan, the sloping sides of which support the fire, which radiates through an opening in the wall of a conical enclosure superposed on the fire-pan. An outer frustoconical casing in most cases surrounds the enclosure, with an opening in register with the opening in the disclosure, and defines an air circulation space through which air circulates upwardly from beneath the fire-pan up into the room. A duct from the exterior of the room to be heated may extend into the space beneath the fire-pan, which space may also contain a water pan to humidify the circulating air. A fire control member is rotatable between the enclosure and the casing so as optionally to obturate the openings therein with either a mesh fire screen or a plate closing off the openings. The fireplace aims to provide complete and controllable combustion of wood fuel, and efficient space heating and, optionally, ventilation of a room in which it is situated.

Abstract: A hybrid collector for collecting solar energy comprised of a plurality of parabolic reflectors cooperating with tube/fin type fluid carrying collector elements, selective ones of which are arranged at the focal points of the parabolas. Additional tube/fin elements are positioned at a spaced distance above the boundary line between adjacent parabolic reflectors. The exterior surfaces of the tube/fin collector elements are treated preferably with a selective coating to provide high absorptivity and low emissivity. The surface areas of the tube/fin elements are also reduced to further contribute to a reduction in emissivity to optimize total absorptance. Location of the tube/fin elements which are off the parabolic reflector focal points cooperate with those located at the focal points to absorb diffuse energy while the tube/fin elements at the focal points absorb beam energy providing for both absorption of beam energy on clear sunny days and absorption of diffuse energy on cloudy or overcast days.

Abstract: A toy balloon is automatically filled with helium gas using a system responsive to gas pressure. A novel check valve in the neck of the balloon is automatically opened upon insertion of a filler element. The flow of gas to the filler element from a constant pressure source is initiated by operation of a pushbutton which opens a valve which is resettable as a result of subsequent pressure build-up in the system. Opening of this valve results in opening a pilot valve through which gas flows to the balloon. Opening of the pushbutton operated valve also applies pressure to an expansible chamber of a timer valve through conduit means and when the pressure in such conduit means and in said expansible chamber become sufficiently high after a predetermined time (established to some degree by conditions in the nozzle and check valve) the timer valve is operated to apply gas pressure to an expansible chamber of the pushbutton valve to return it to its closed position thereby interrupting all flow to the balloon.

Abstract: A method of disrupting vapor films formed in film boiling in boilers, in which method transient electrical discharges are effected either in the boiler liquid or in a body of liquid in acoustic communication with the boiler liquid. The electrical discharges are effected at one or more selected locations in the boiler to produce shock waves which act on surfaces of the boiler liquid space where vapor films are to be disrupted. By disrupting such vapor films there is enabled an improvement in the heat transfer rates per unit area across the interface between the fire space and the liquid space of a boiler. There are also disclosed various arrangements in boilers for generating these shock waves. Electrical discharges may be effected between a pair of electrodes mounted in the boiler or between an electrode and an adjacent wall of the boiler, and several mounting configurations for electrodes in boilers are described.

Abstract: The open-face frames of electric heat modules used with a pair of centrifugal fans in a roof top type air conditioning unit are mounted with their upwardly open faces spaced downwardly away from the downwardly facing discharge opening of the fans, rather than up tight against the discharge opening, so that there will be a bypass of at least some of the discharge air from the fan around the module to reduce the resistance to air flow imposed by the module. The arrangement achieves a good balance between the use of relatively high watt density heater while avoiding undue resistance to air flow through the heater. The invention also provides a convenient module mounting arrangement in which the inboard end walls of the modules are supported in a complementary hook and eye arrangement with mounting straps depending from the sides of the discharge openings of the centrifugal fans.

Abstract: A passive method for locating the position and inclination of a flame front, within an oil-shale retort of known dimensions and location during an in situ combustion of the retort involving detecting the sound generated by the flame front, by two matched detectors separated by a fixed known distance. The pair of matched detectors are suspended vertically in a liquid-filled well which was drilled essentially parallel to the side wall of the retort. The outputs of the two detectors are fed directly to a differential amplifier and the resulting difference signal is monitored as a function of depth as the pair of detectors are raised and/or lowered in the well. The minimum in this signal corresponds to the position of the flame front within the retort. Repeated measurements in various observation wells establish the inclination of the flame front.

Abstract: Lubricant is circulated from a lubricant reservoir to the bearings of a rotary rock bit and back to the lubricant reservoir by a lubricant circulation system that is operated by rotation of the cone cutter upon the bearing pin of the bit. A spiral groove system in the inner surface of the cone cutter operates as a viscous or ram pump when the cone cutter is rotating against the corresponding bearing surface of the bearing pin and provides the pumping action for circulating the lubricant. A seal is positioned between the rolling cone cutter and the arm of the bit to maintain lubricant in the bearing area and to prevent fluid in the borehole from entering the bearing area. A lubricant reservoir is located in the bit body. A first passage connects the lubricant reservoir with the bearing area to channel lubricant from the lubricant reservoir to the bearing area. A second passage extends from the bearing area to the lubricant reservoir to allow lubricant to be channeled back to the lubricant reservoir.
