  • Publication number: 20040256477
    Abstract: A method and apparatus are provided for maintaining a temperature between a first value and a second value. The method and apparatus utilize a heat transfer device capable of cycling through a series of cycles, the device being capable of changing the temperature from the second value to the first value when operational. During each cycle the device transfers heat for a first period of time when the temperature reaches the second volume until the first value is reached and thereafter the device stops transferring heat. The first period of time is compared to a desired cycle-on period of time during each cycle and the second temperature value then is adjusted for a subsequent cycle of the device so the first period of time when the device transfers heat approaches the desired cycle-on period of time. There may also be provided temperature controls for a liquid heater having a jacket containing the liquid. The jacket has an inner heated wall and an outer wall spaced apart from the inner wall.

  • Publication number: 20040007196
    Abstract: A heater for a liquid has a combustion chamber, a jacket for the liquid extending about the combustion chamber and a burner head assembly connected to the combustion chamber. The burner head assembly includes a housing having a burner mounted thereon and a hollow interior. A control module and a fan are mounted in the hollow interior, the fan being connected to an electric motor. A compressor and a fuel pump are mounted on the housing and are operatively connected to the electric motor. The control module may include controls for exercising components of the heater prior to combustion, thereby verifying operation of these components. Preferably there is a speed control for the motor, such as a closed loop speed control which regulates motor speed and accordingly output of the heater. Preferably there is a backup system using a lookup table in the event that the closed loop speed control fails.

  • Patent number: 5003826
    Abstract: A device for supporting a long cable to permit the ends of the cable, such as swaged end fittings, to be tested by a conventional tension/compression tester. The device includes a drum upon which the cable is wound. The drum is supported by a pair of vertical flanges which in turn are connected to a movable platform of the tension/compression tester. One end of the cable is connected to a fixed base of the tester. A small section of the remaining portion of the cable that is not wound around the drum is engaged by a movable clamp which is fastened to one of the vertical flanges. The cable is tested by movement of the platform away from the base until a predetermined load is reached. A majority of the applied force is absorbed by the portion of the cable that is wound on the drum. The remainder of the applied force is absorbed by the adjustable clamp. Consequently, during the test there is limited slippage of the cable on the drum.

  • Patent number: 4823396
    Abstract: A device is provided for automatically inspecting a fastener for defects prior to its installation in an assembly operation. The fastener is propelled by air or gravity along a feed line. The inspection device is connected in the feed line and has a cam member that is positionable into the fastener's path of travel for blocking it at a certain position. A television camera produces a video image of the stopped fastener, which shows the fastener's actual dimensions. A computer then compares the actual dimensions with the fastener's desired, which are prestored in the computer's memory. If the two substantially match, the fastener is known to be acceptable for installation.

  • Patent number: 4753555
    Abstract: An apparatus and method for first drilling a hole in a workpiece by utilizing a locating jig, and then inspecting the hole to insure it is drilled to the proper diameter. There is an inspection device having an inspection probe that is pivotally mounted about a universal mounting device so that the lower inspection end of the probe is able to deflect laterally to fit in the drilled hole so as to be centered therein. This arrangement compensates for any misalignment in the positioning of the inspection apparatus relative to the earlier alignment of the drilling apparatus.

  • Patent number: 4698516
    Abstract: A hydro-electric power plant specifically structured to operate in connection with a water reservoir supplied from a natural body of water such as an ocean, lake, etc. and which is structured to be at least partially self-sufficient while at the same time providing excess electrical energy in the operation of an auxiliary production facility such as an aluminum smelting plant.

  • Patent number: 4638566
    Abstract: Improvements in hole angularity gauges. Known gauges require a plug to fit precisely into the hole, or have limited accuracy and/or require multiple readings. The gauge (10) of the invention provides a tapered plug (16) that will fit snugly into holes having diameters varying from a standard within reasonable tolerances. An indicator member (42) is slidably and pivotably attached to a slider member (56) carried by member (12, 14) of which plug (16) is a part. Spring (80) biases member (42) into contact with an object (2) around the hole being tested when plug (16) is wedged into such hole. Member (42) has two spaced legs (46) having rounded bottom ends (48) that contact object (2), and an indicator arm (52) which extends up through a sleeve portion (14) of member (12, 14). When the head (54) of arm (52) protrudes from a radial slot (36) in sleeve (14), the hole being tested deviates from normal to the surface of the object (2) by more than the permissible amount.

  • Patent number: 4470312
    Abstract: A torque measuring device has a torsion bar with effective length adjustable to show different energy absorption capability. One end of the torsion bar's effective length is held stationary while a torque from a torque controlled winding tool is applied to the other end through a one direction of rotation clutch. The actual torque applied to the torsion bar is measured after which the torque on the bar is released.

  • Patent number: 4367592
    Abstract: In order to check the strength and seal of a fitting that has been swaged on a tubular part, the difference between the nominal inside diameter of the tube and the larger diameter of an inside circumferential groove formed in such tube by swaging of the tube wall radially outwardly into a mating groove of the fitting is measured by a handheld gauge apparatus that includes a probe adapted to be inserted into an open end of the tube adjacent the fitting to perform successive, comparison measurements of the tube's interior wall surface, first at a location axially spaced from the swaged groove, and secondly at the groove. The probe includes a cylindrically shaped probe head of a diameter less than that of the tube's nominal inside diameter so that the probe head can be inserted and cocked at a slight angle relative to the tube axis, and a pivoted arm having a feeler tip disposed in a slotted opening in the probe head and so mounted as to be movable transversely relative to the circumference of the probe head.

  • Patent number: 4103952
    Abstract: The specification describes a combination bag and scoop used for cleaning up waste material when walking one's pet. The bag includes a closed bottom portion for holding waste material and an upper portion having an open mouth for insertion of waste material into the bag and closing means for closing the bottom portion of the bag after placing waste material therein. The bottom portion is constructed of a flexible, impermeable material such as high density polyethylene. The upper portion which is also preferably constructed of a high density polyethylene includes two relatively flat parallel sidewalls adjacent to one another. Each of the sidewalls is provided with a finger insert at one end thereof with both of the inserts located at the same end of the upper portion. The upper portion is rigid to the extent that upon insertion of a finger and a thumb or a pair of fingers in the inserts, the mouth can be spread open by bowing the sidewalls.
