Title: Glass sheet press bending system
Inventor: NITSCHKE DEAN M
IPC: C03B27/04
Filed: 1987-03-13
Granted: 1991-08-06
Abstract: GLASS SHEET PRESS BENDING SYSTEM         ABSTRACT            A glass sheet press bending system (20) disclosed has a bending station (30a,30b,30c,30d) for providing press bending between upper and lower molds (32,42) without intrusion into or through a conveyor (26) on which glass sheets are heated prior to the bending.          The upper mold (32) is positioned above the conveyor (26), while the lower mold (42) is movable horizontally at an elevation above the conveyor from a first position adjacent the upper mold to a second position below the upper mold whereupon vertical movement therebetween performs the press bending between the molds. A transfer mold (48) receives the bent glass sheet from the upper mold (32) for cooling. Two embodiments of the bending station (30a ,30c) have the lower mold continuously positioned within a heated ambient to provide a relatively hot lower mold that reduces breakage, while two other embodiments of the bending station (30b,30d) have the lower mold (42) movable out of the heated ambient after the press bending to provide a cooler mold that does not mark the glass sheets. Two embodiments of the bending station (30a,30b) have a lower mold (42) with a fixed curved shape, while the other two embodiments of the bending station (30c,30d) have a lower mold with first and second mold portions (60,62) that are movable with respect to each other to provide initial and final stages of the press bending operation. Each embodiment of the bending station has particular utility when utilized with a quench station (54) located on the opposite side of the heating conveyor (26) and the upper mold (32) as the lower mold (42) in its first position.

Title: Air-duct connecting section with seal
Inventor: SCHAUER MARKFRIED
IPC: F16L23/00
Filed: 1987-06-02
Granted: 1991-01-02
Abstract: ABSTRACT           A flange for connecting two air ducts to one another has a pair of spaced, generally parallel walls and a pair of spaced,  generally  parallel  legs  fast  with,  and  extending perpendicular to, the walls.  The flange legs are designed to embrace and grip a wall of an air duct while the flange walls define a chamber adapted to receive one leg of an angle serving to connect the flange to a neighboring flange.  One of the flange legs is plastically deformed so as to define a cavity and has a surface facing the other flange leg.  The cavity is open to this surface and accommodates an elastomeric seal which projects from the cavity to a location beyond the surface. The  seal  is elastically compressed in the cavity to retain the seal therein and such compression may be achieved by plastically deforming the respective flange leg after the seal has been positioned on the same.

Title: Pressure assist detonating bar and method for a tubing conveyed perforator
Inventor: WESSON DAVID S
IPC: E21B43/1185
Filed: 1987-07-31
Granted: 1991-03-12
Abstract: Abstract of the Disclosure A detonator bar has an outer housing, an inner housing connected to the outer housing by at least one first fran-gible member, an explosive charge disposed in the inner housing, and a firing piston with firing pin held in the inner housing by at least one retaining dog and at least one second frangible member.  Operation occurs in response to a relatively small impact force between the detonator bar and a perforator or other explosive object located in a subter-ranean well.  This relatively small impact breaks the at least one first frangible member.  Thereafter, a fluid pres-sure existing in the subterranean well, such as a hydrosta-tic pressure within a tubing string on which a perforator is conveyed, is used to exert a sufficient force to break the at least one second frangible member after the at least one retaining dog has been released by downward movement of the outer housing relative to the inner housing, which relative movement occurs only after the initial impact force has bro-ken the at least one first frangible member.

Abstract: LATCHING APPARATUS FOR AN ELECTRICAL CONNECTOR                  ABSTRACT            A latching apparatus is provided for an electrical connector of the type having a housing including a plurality of electrical contacts therein.  The latching apparatus comprises a deflectable arm that is pivotally supported on the connector housing, the pivot being disposed generally between the two ends of the pivotal arm such that both opposed ends of such arm may move relatively toward and away from the connector housing.  The front end of the deflectable arm is provided with a latch for attachment to a complementary latch of a mateable electrical connector or the like.  A slidable locking bar is captively supported on the housing for movement between a first position and a second position.  The locking bar and deflectable arm include cooperative locking means disposed on both sides of the pivot that are operative in the first position to prevent movement of both ends of the latching arm and in the second position to permit free movement of both arm ends.  As such, when the bar is in the first position, secured locking engagement of the latch is provided when attached to the mateable connector, while when the locking bar is in the second position, the free movement of the deflectable arm permits ease of attachment to or detachment from the mateable connector.

Title: Sonic agitator with multi phased vibration bars
Inventor: BODINE ALBERT G
IPC: B01F11/00
Filed: 1988-02-10
Granted: 1991-03-05
Abstract: SONIC AGITATOR WITH MULTI PHASED VIBRATION BARS                  ABSTRACT OF THE DISCLOSURE     Three or more (preferably an even number) of hollow vibration bars are joined together at one end thereof with the bars spaced from each other and with their longitudinal axes in substantially parallel relationship.  Each of the bars has an unbalanced rotor mounted therein which when rotatably driven will generate vibrational energy in the associated bar. The similar rotors of the bars are phased with relationship to each other to generate a combined vibrational force pattern in a liquid in which the bars are immersed which affords optimum agitation of the liquid in an omnidirectional manner.   The vibration at the juncture between the multiple bars is kept at a minimum by virtue of the cancellation of the force vectors generated by the bar members at this point.

Granted: 1991-05-07
Abstract: Abstract of the Disclosure A pyrolytic self-clean gas wall oven having a bake and broil burner wherein a baffle separates the secondary air supply for the bake burner from the broil burner primary combustion air flow path so that, when the broil burner is off, combustion products from the bake burner are prevented from recirculating back to the bake burner via the broil burner and its primary combustion air supply path.  Further, the oven has fans for moving cooling air around the outside to limit the external surface temperatures.  The cooling air and the combustion air have independent flow paths so that the flame characteristics are not affected.  The oven may have two oven compartments each with its own bake and broil burners.

Abstract: ABSTRACT    Apparatus and method for  installing an array of rotatable  turbine  blades  each  having  an  integral shroud  segment.     A  removable  blade  anchor   for installing the turbine blades comprises a root portion positionable  in  registry with  a  turbine  rotor  blade groove,  a  support  member  extending  from  the  root portion for  supporting  a  first of  the  blades  to be installed  and  an  anchor  support  extending  from  the support member and positionable against the rotor  to secure  the  support  member  against  circumferential forces.   The  installation method comprises the steps of positioning the removable blade anchor  in a rotor groove and then wedging a plurality of blades in place about the rotor so that the integral shroud segment of each blade abuts an adjacent integral shroud segment and all shroud segments are forced against the blade anchor.    Next,  a  first  portion  of  the  blades  are rewedged in order to force the first portion of blades away from the blade anchor.  The blade anchor is then removed without disturbing the tight abutment between the  plurality  of  blades  and  additional  blades  are installed to complete the blade row.
