  • Patent number: 4408716
    Abstract: A flue gas heat recovery system for use in conjunction with a forced hot air furnace, such system having two conventional heat exchangers, one located in the flue leading from the combustion chamber of the furnace to the chimney, and the other in the cold air chamber of the furnace adjacent the blower fan. Such heat exchangers each have a core connected into a hydraulic circuit which contains an electrically driven circulating pump controlled by a thermal device having a heat actuated switch located in the upper portion of the heat plenum in the furnace.Such switch is connected into an electric circuit adapted to activate the blower fan and circulating pump simultaneously. The core of the heat exchanger located in the flue of the furnace absorbs a substantial portion of the heat in the exhaust gases which would otherwise be lost to the atmosphere, and utilizes such heat to increase the temperature of the air supplied to the intake of the blower fan in the cold air chamber of the furnace.

  • Patent number: 4293299
    Abstract: A load support device for supporting metal slabs as they are moved through a heat furnace having therein a plurality of pipe beams through which a coolant is continuously circulated. The load support device consists of a saddle member mountable on the pipe beams, and having therethrough a longitudinally disposed central opening. A replaceable core, supported in the central opening and removably attached to the saddle member, has on the upper end thereof a head for supportively engaging the metal slabs.A projection on the lower end of the replaceable core extends below the saddle member so that it will be surrounded by coolant thereby greatly increasing the rate of heat transfer from the replaceable core, which substantially reduces the operating temperature of the head. Deformation, cracking, spalling and burn-out of the head is thus significantly retarded so that those cores with badly worn heads can be replaced when the furnace is shut down for routing inspection and general maintenance.

  • Patent number: 4291921
    Abstract: A vehicle wheel hub cap having a stylized disk with a pair of spaced openings therein adjacent the outer periphery. An outstanding collar on the disk supports thereon an inflatable tube. A flared retainer rim on the outstanding collar holds the inflatable tube in its assigned position on the collar. An outwardly disposed valve stem on the inflatable tube is aligned with one of the spaced openings in the disk. A removable plug in the opening aligned with the valve stem is adapted to enter into a locking engagement with the disk. The inflatable tube when pressurized expands so as to holdably engage the rim of a conventional vehicle wheel. The hub cap is thus secured against accidental loss or theft, and can be removed only after the inflatable tube has been depressurized.

  • Patent number: 4244303
    Abstract: A combination picture frame and repository in which one of the frame members is movable to provide access to a secret inner storage compartment for hiding money, jewelry, and other valuables. The movable frame member may be adapted either to detach or pivot from its assigned position on the frame, and is yieldably held in place preferably by magnetic components. The frame may either be hung from a wall or placed in an upright position on any appropriate support such as a table of desk.

  • Patent number: 4211143
    Abstract: A musical instrument having an adjustable elongated member supported in an upright position on a collapsible base. A flat flexible sheet of metal, or other suitable materials capable of producing a musical tone when struck, is adjustably mounted on the upper end of the elongated member. An operator lever, pivotally mounted on the collapsable base, is connected to the flat flexible sheet by a cable. An actuator pedal on the operator lever enables it to be conveniently manipulated so as to selectively flex the flat flexible sheet when it is being struck by a percussive implement thereby producing variations in tone. A further variation in tone can be achieved by drawing a conventional violin bow across the edge of the flat flexible sheet as it is being flexed.

  • Patent number: 4134472
    Abstract: A combination muffler and air filter, having a central tubular member with spaced longitudinally disposed elongated slots. A disposable canister on the central tubular member is removably held in position by retainer caps engaged on the ends of the central tubular member. One of the retainer caps is adapted for connection to the exhaust conductor from a pneumatically operated device or compressed air system. The other retainer cap has therein an annular sump, connected by lateral ducts to a drain opening. The disposable canister has a perforated cylinder encasing a series of stacked annular members having both muffling and filtering properties. A perforated sleeve in the disposable canister supportively engages the inner periphery of the stacked annular members. A closure disc, fixed on each of the perforated cylinders, holds the stacked annular members in a compact and compressed condition.

  • Patent number: 3996775
    Abstract: An anchoring device for securing bicycles, motorcycles, snowmobiles, power mowers and other similar items stored in home garages. The anchoring device has an elongated bolt which can be permanently installed in a wall of the garage. A non-rotatable head is slidably mounted on the free end of the elongated bolt. A `U` bolt is threadably connected on one end to the head, and provided on the other end with an eye. A hasp threadably engaged on the elongated bolt receives therethrough the eye on the `U` bolt to which a padlock is attachable for securing a chain or cable passing through and around the items to be protected in the customary manner.
