Abstract: STOVE CONSTRUCTION                 Abstract of the Disclosure A stove construction including a firebox that defines a combustion chamber.  Air is aupplied to the upper portion of the combustion chamber through a pre-heat manifold having outlet apertures spaced along the sides.  Air is drawn from the atmosphere into the mani-fold where it is preheated and discharged in the form of jets toward the sloping side walls of the firebox and into the flow path of the waste gases of combustion. Due to the restriction to flow caused by baffles located in the spaces between the sides of the manifold and the sloping sidewalls, a portion of the mixture of air and waste gases is directed downwardly along the surface of combustion plates, which are spaced from the walls of the firebox, back toward the primary com-bustion area.  The waste gases are further combusted as they pass downwardly along the heated combustion plates.  The recirculation achieves complete combus-tion of the waste gases.

Abstract: APPLICATION OF:     LESLIE O. DAYE FOR:  CLOSED CIRCUIT HEATING SYSTEM     ABSTRACT OF THE DISCLOSURE         Fuel is burned in the lower chamber of a furnace with hot products of combustion rising past an air-to-air heat exchanger to an upper chamber to which outside air is supplied for secondary combustion.  Air is heated in a compartment above the upper combustion.  Air is heated in a compartment above the heat exchanger, through a closed circulation system to a duct within a stone-filled heat storage chamber, thence to an air-to-water heat exchanger, through the stones in the heat storage chamber and back to the heating compartment and air-to-heat exchanger.  Water heated in the air-to-water exchanger is used for space heating purposes, as in baseboard hot water heaters. Some of the heat may also be used to power a heat engine and/or to dry wood to be used as fuel in the lower combustion chamber.

Abstract: ABSTRACT OF THE DISCLOSURE          A single-acting, clearance sensing slack adjuster for brakes is provided.  The slack adjuster includes a displaceable brake actuation means (28), a rotatable driving member (52), a rotatable intermediate member (60) and a rotatable driven member (56).  The driven member is in driving relationship with a rotatable adjustement member (50) which is rotatable in a given direction to advance a brake friction member (32) to maintain the running clearance (38) within predetermined limits.  Means (76-80) are provided to rotate the driving member in the slack decreasing direction of rotation in response to greater than predetermined movement (82) of the brake actuation means.  A first coil clutch (20) couples the driving and intermediate members while a second coil clutch (72) couples the intermediate and driven members.          One clutch (72) delivers torque in the given direction in its low torque transmitting capacity direction of rotation and that torque capacity is less than is required to rotate the rotatable actuation members when the brake friction members are engaged.

The apparatus and process utilize heat of compression for vaporizing the liquid.  The apparatus includes a still (10), a closed refrigeration system (12), an auxiliary condensing coil (24) separate from refrigeration system (12), and a valve (28) for controlling heat extraction by auxiliary coil (24).  In a particularly useful embodiment, the apparatus further includes a trough (41) for collecting the condensed vapors,  The trough is located with still (10).  Auxil-iary coil (24) extracts from the vapors, heat in excess of that necessary to maintain thermal balance in the apparatus.       The novel process of the present invention includes the steps of compressing a gaseous working fluid to a high pressure and adding heat of compression thereto; transferring heat including the heat of com-pression from the working fluid to a liquid in still (10), as a result of which the liquid is vaporized and the resulting working fluid contains sensible heat; passing the resulting working fluid to evaporator coil (18) whereby the working fluid entering evaporator coil (18) contains the sensible heat; and removing from the vapors resulting from vaporization of the liquid, heat in excess of that necessary to maintain thermal balance in the apparatus (12). The excess heat is removed by auxiliary condensing coil (24), which is separate from the refrigeration system.

Abstract: FOLDABLE AND PORTABLE BICYCLE WITH COMPACT STEERING BEARING            ABSTRACT OF THE DISCLOSURE       A foldable, portable bicycle in which the handlebar assembly, the seat assembly, the pedal crank and the frame are foldable quickly and easily into a compact and regular-shaped  package  that  is  easily portable and storable,  and are unfoldable with similar speed and ease into a safe, durable and comfortable bicycle that accommodates adults of normal size. The frame is designed with a low profile that is substantially the same in height and thickness as the dimensions of the wheels and their supports,  and  the handlebar and seat assemblies extend upwardly to normal height, but fold and collapse, along with the pedals,  to substantially within the confines outlined by the folded frame.      The steering bearing is housed in a front wheel mount in the form of a narrow arcuate band on the front end of the frame, and has a height that is substantially less than its diameter, about one-quarter the diameter as disclosed. The bearing has at least one set of rolling bearing elements that are confined, both laterally and vertically, in races that are defined between the band and bearing rings on the handlebar assembly and the front wheel support, these being connected through the front wheel support by connecting means that draw them together and against the opposite ends of the bearing.      In one embodiment, two series of ball bearings are closely spaced, vertically, on opposite V-grooved sides of an internal  flange on the band, and held in the grooves by oppositely opening v-grooves in bearing rings above and below the flange. In another, a single set of ball bearings is confined in an inwardly opening V-groove in the band by beveled edges of two bearing rings cooper-ating to form an outwardly opening internal V-groove for the balls. In each case, the increased lateral separation of the balls compensates for the reduced axial length to enable the vertically compact bearing to sustain the torque and thrust loads encountered in use.
