Patent number: 6273183Abstract: A heat exchanger is disclosed of the type having stacked plate pairs or tubes defining flow passages, with turbulizer located inside such flow passages. The turbulizers are of the expanded metal type having rows of convolutions. The convolutions are interrupted periodically to form non-convoluted pressure recovery zones located between or downstream of the convolutions. Also, the rows of convolutions can be grouped and spaced apart to provide longitudinal neutral zones between groups of adjacent rows of convolutions. The pressure recovery zones and longitudinal neutral channels reduce pressure drop in the heat exchanger without appreciably reducing heat transfer.Type: GrantFiled: June 9, 2000Date of Patent: August 14, 2001Assignee: Long Manufacturing Ltd.Inventors: Allan K. So, Peter Zurawel, Dan Constantin Stefanoiu

Patent number: 6253837Abstract: A by-pass valve and a heat exchanger employing same is disclosed where the by-pass valve makes a short circuit from the heat exchanger inlet to the heat exchanger outlet to disable the heat exchanger under certain temperature conditions. The by-pass valve includes a housing defining a chamber. Three main ports communicate with the chamber, one being a valve port. A temperature responsive actuator located in the chamber operates a spring loaded valve to open and close the valve port. The valve port can be connected to one of the heat exchanger inlet or outlet, the other main ports are then connected in series with the other of the heat exchanger inlet or outlet.Type: GrantFiled: June 9, 2000Date of Patent: July 3, 2001Assignee: Long Manufacturing Ltd.Inventors: Thomas F. Seiler, Dario Bettio, Yuri Peric

Patent number: 6249485Abstract: A mechanical device converts one time base to another without using gears to do so. A mechanical adder adds a constant into an accumulator at regular intervals. The interval is generated by the overflow of the accumulator. In the case where a signal is to be generated once every solar year from a wheel that rotates only once per day, the fractional number 1/365.242198 is added to the accumulator each day by the rotation of a day wheel. Whenever the accumulation overflows, the one-year signal is generated. The fractional portion of the accumulated sum remains in the accumulator, such that round-off errors do not accumulate over time. The preferred adder is digital, such that this computation may be carried out to any desired level of precision. Additionally, the same design, but with a different constant, may be used to generate other intervals (e.g. for lunar months).Type: GrantFiled: December 10, 1997Date of Patent: June 19, 2001Assignee: The Long Now FoundationInventor: W. Daniel Hillis

Patent number: 6244334Abstract: Self-enclosing heat exchangers are made from stacked plates having raised peripheral flanges on one side of the plates and continuous peripheral ridges on the other side of the plates, so that when the plates are put together, fully enclosed alternating flow channels are provided between the plates. The plates have raised bosses defining fluid ports that line-up in the stacked plates to form manifolds for the flow of heat exchange fluids through alternate plates. Turbulizers in the form of half-height shim plates are located between the plates. The shim plates have central portions defining flow augmentations extending from one side of the plates only, and the plates have peripheral edge portions that are coterminous with the respective continuous ridges raised peripheral flanges.Type: GrantFiled: February 4, 2000Date of Patent: June 12, 2001Assignee: Long Manufacturing Ltd.Inventors: Alan K. Wu, Bruce L. Evans

Publication number: 20010001691Abstract: A composite material has plate 4 having holes and a bonded to a first member to form an intermediate layer, and a second member which is made of a material different from the first member 1 laminated onto the intermediate layer 2 while charging a portion of the second member 5 into the holes 3 of the intermediate layer 5 to form a composite material 6. The holes 3 of the plate 4 which forms the intermediate layer 2 have a shape in such that the charged second member exerts a resisting force against a tensile stress applied in a direction perpendicular to the surface of the first member 1, e.g., a shape having a first hole opened on the side of the second member and a second hole communicated with the first hole and having a space not overlapped with the first hole, or a shape that an opened area on the side of the second member is smaller than that on the side of the first member.Type: ApplicationFiled: May 16, 1997Publication date: May 24, 2001Applicant: Long Than TrongInventor: LONG THAN TRONG

Patent number: 6220340Abstract: A heat exchanger is disclosed having a plurality of stacked plate pairs or tubes, each having a predetermined internal cold flow resistance. A bypass conduit is included in the stack of plate pairs or tubes. The bypass conduit includes a central row of spaced-apart, mating dimples defining longitudinal flow channels on either side of the dimples for bypass flow through the bypass conduit under cold flow conditions. The longitudinal flow channels have a height and width such that the cold flow resistance therethrough is less than the cold flow resistance through the stacked plate pairs or tubes. In normal or hot flow conditions, the dimples create flow resistance by forcing the fluid flowing through the bypass conduit to change velocity and direction. This forces more oil to flow through the stacked plate pairs or tubes increasing heat transfer performance.Type: GrantFiled: February 29, 2000Date of Patent: April 24, 2001Assignee: Long Manufacturing Ltd.Inventors: Alex S. Cheong, Yong N. Lee

Patent number: 6220394Abstract: A weight operated mechanical drive consists of a cylindrical weight that is suspended by a helically threaded drive screw which passes through and engages with complementary threads within a bore defined along a rotational axis thereof. The weight turns the drive screw as it falls due to the force of gravity. The weight is prevented from rotating about the axis of the screw while it is failing by a wheel which is attached thereto and which rolls against a retaining bar that runs alongside the weight along the weight's path of travel. The retaining bar is also used to wind the weight. To do so, the retaining bar is rotated around the rotational axis of the drive screw. This action forces the weight along a path defined by the helical threads of the drive screw. The retaining bar is formed as a helix around a column through which the weight drops.Type: GrantFiled: October 21, 1999Date of Patent: April 24, 2001Assignee: The Long Now FoundationInventor: W.

Patent number: 6199626Abstract: Self-enclosing heat exchangers are made from stacked plates having raised peripheral flanges on one side of the plates and continuous peripheral ridges on the other side of the plates, so that when the plates are put together, fully enclosed alternating flow channels are provided between the plates. The plates have raised bosses defining flow ports that line-up in the stacked plates to form manifolds for the flow of heat exchange fluids through alternate plates. Rib and groove barriers are formed in the plates inside the peripheral flanges and ridges. The barriers prevent short circuit flow on one side of the plates and promote flow to remote areas on the other side of the plates, to improve the overall efficiency of the heat exchangers.Type: GrantFiled: February 4, 2000Date of Patent: March 13, 2001Assignee: Long Manufacturing Ltd.Inventors: Alan K. Wu, Allan K. So, Bruce L. Evans, Thomas F. Lemczyk

Patent number: 6126589Abstract: A flexible therapeutic magnetic sheet, e.g., fabricated from randomly-distributed ferromagnetic particles mixed in a plastic resin and formed into a sheet. A magnetic field is applied to the sheet to permanently magnetize the sheet according to a spiral pattern. The spiral pattern comprises a Northern pole spiral interlaced with a spiral pole Southern. When the therapeutic sheet is applied to the skin of a person or an animal, the ions and electrolytes in the blood traverse alternating polarity magnetic fields. The alternating polarity magnetic fields exert magnetic forces in alternating directions on the ions and electrolytes in the blood, thus generating heat in the blood vessels and increasing the blood circulation.Type: GrantFiled: April 30, 1999Date of Patent: October 3, 2000Assignee: Brooks Industries of Long IslandInventor: David H.
