Abstract: 60,152-476 METHOD OF INSTALLING SELF-ATTACHING FASTENER AND APPARATUS                         ABSTRACT OF THE DISCLOSURE   An   improved   die  member   and  method   of   attaching   a self-piercing and riveting fastener to a panel wherein a slug pierced from the panel by the riveting fastener is securely staked in the barrel portion of the fastener during the installation of the fastener.  The staking method includes driving a plurality of staking projections into said slug,  thereby pinching said slug between the projections and a barrel  side  wall.   This  pinching  action  causes  the  slug  to  deform outwardly  and  lodge  between  the  side  walls  of  said  fastener.   The staking projections are preferably arranged around the perimeter of the die post and in a most preferred embodiment,  the projections have a canted side wall  proximal  the wall,  forcing a portion of said slug toward the barrel side wall, when said slug is pinched between said canted side wall and a bottom wall of said fastener.

Title: System and apparatus for recovery of turpentine from thermomechanical pulping process
Inventor: REYNOLDS ELLIS W
IPC: D21C11/10
Filed: 1990-08-22
Abstract: ABSTRACT           There has been provided a system and apparatus for recovering turpentine from a thermomechanical pulping process for making paper, which thermomechanical pulping process utilizes a plug screw conveyor for squeezing and feeding pulp chips.  The thermomechanical pulping process is conventional.  The liquid effluent from said plug screw conveyor contains an appreciable amount of turpentine.  The liquid effluent is collected under superatmospheric pressure and flashed into vapor/liquid separator by releasing the pressure on the liquid.  This vapor is condensed in a suitable condenser and the condensate collected in a decanter where the turpentine collects as a separate phase and the water also as a separate phase.  Condensate from various vents in the conventional thermomechanical pulping process may be collected for more nearly complete removal of turpentine and other oleoresinone components.

IPC: H01Q5/00
Filed: 1990-12-19
Abstract: ABSTRACT OF THE DISCLOSURE     A multi-band antenna is adapted to receive signals in the AM/FM bands and to receive and transmit signals in a significantly higher frequency band such as that used for cellular telephone.  An AM/FM band antenna is formed of a tubular rod, and a higher frequency band antenna is formed using a center-fed coaxial dipole mounted on top of and coaxially with the AM/FM antenna.  The dipole is fed by a coaxial rod attached to a coaxial cable extending through the AM/FM antenna.  A cylindrical choke is disposed about the coaxial rod and is spaced a predetermined distance from the dipole antenna to reduce coupling between the AM/FM antenna and the high-frequency antenna.  The choke functions to position the input impedance of the high-frequency antenna at the base of the choke in a manner so that a short matching transformer may be used at the base of the choke for connection to the coaxial cable.      In matching the antenna in this manner at the base of the choke, the best possible VSWR characteristics of the antenna are preserved and the radiation pattern of the antenna's main lobe extends horizontally along a horizontal axis.

Filed: 1991-11-04
Abstract: The present invention is an enhanced tubular heat exchanger for a furnace.  The tubes of the heat exchanger include an enhanced portion which has a smaller cross-sectional area than the flue portion, in the form of an elliptically shaped tube.  The enhanced portion further includes turbulators to promote the heat exchange from the heated flue gases.  Circulation of air around the exterior of the tubes is also facilitated because the enhanced portion is disposed at a small angle relative to the flue portion.  A plurality of tubes are disposed within the heat exchanger so that the circulation air first flows over the enhanced portions then over and around the generally cylindrical portions.  This lowers the initial pressure drop in the circulation air flow and thereby facilitates the circulation of and heat transfer to the air being heated.
