Title: Single column process and apparatus for producing oxygen at above-atmospheric pressure
Inventor: NAUMOVITZ JOSEPH P
IPC: F25J3/04
Filed: 1994-04-21
Abstract: PROCESS AND APPARATUS FOR PRODUCING OXYGEN      AT AN ABOVE-ATMOSPHERE PRESSURE                             ABSTRACT    A process and apparatus for separating air in which a refrigerant stream produced at the top of a single column is expanded with the performance of work. Such expansion can be carried out in an expansion machine coupled to a recycle compressor by an energy dissipative brake. An oxygen stream is removed from a bottom region of the column and a compressor compresses an oxygen stream to column pressure which is at an above atmospheric delivery pressure. After compression, the oxygen stream is divided into two partial streams. One of the two partial streams is fed back into a bottom region of the column as a vapor to provide boil up while the other of the two partial streams is taken as a product which having been derrived from the compressed stream is therefore at the above-atmospheric delivery pressure. The refrigerant stream is heat exchanged countercurrently with incoming air to be separated in order to add refrigeration.

Title: Swivel recliner/rocker chair having preloaded base assembly
Inventor: FAY JUDY E
IPC: A47C3/027
Filed: 1994-11-09
Abstract: A swivel recliner/rocker chair which even more effectively resists unwanted rocking of the swivel base member thereof when the chair is rocked forwardly of the swivel base member, and which further is limited in its rearward reclining or rocking motion to a predetermined degree so as to thereby limit rocking of the swivel base member that might occur if the chair is reclined or rocked rearwardly of the swivel base member to an excessive degree.  The chair includes a pair of rocker blocks having a flat section formed thereon and a pair of spring assemblies having upper and lower bracket members.  The upper bracket members are secured to the rocker blocks and the lower bracket members are secured to side members of a base assembly such that the rocker blocks rock on the side members during reclining or rocking movement of the chair.  The upper and lower bracket members are further secured to their respective rocker blocks and side members such that each spring assembly exerts a slight tensioning force to urge the seating section of the chair into a slightly reclined position even when there is no occupant seated  in  the  chair.    This  substantially  eliminates  any possibility of forward rocking motion of the swivel base member when the chair is rocked forwardly.  The flat portions of each rocker block further serve to limit the maximum reclining and rearward rocking movement of the seating section to thereby avoid any undesirable rocking of the swivel base member as the seating section is reclined or rocked in a rearward direction.

Patent CA-2136916-A1 (CA)
Title: Inertia latch assembly for seat hinge mechanism
Inventor: WHALEN JOHN F
IPC: B60N2/20
Filed: 1994-11-29
Abstract: An inertia-sensitive seat hinge mechanism allows rotation of a seatback relative to a seat bottom under normal use conditions and yet prevents such rotation in response to deceleration forces exceeding a predetermined threshold level.  The seat hinge mechanism includes a lower hinge member connected to the seat bottom and an upper hinge member connected to the seatback and an inertia-sensitive latch assembly. The inertia-sensitive latch assembly includes a component carried by the upper member which defines first and second stop surfaces. The first stop surface limits rotation of the upper hinge member in one direction. An inertial actuator is rotatable with respect to the upper hinge member and includes an engaging finger for engaging the second stop surface when the upper hinge member attempts to rotate in an opposite direction due to exertion of the predetermined deceleration forces thereon. The inertial actuator also includes a projection located adjacent a center of rotation. Moreover, the inertial actuator has a center of gravity spaced from the center of rotation. A release lever engages the projection to rotate the inertial actuator into a normal position against the component when the upper hinge member is fully rotated against the first stop surface. A biasing device, located on the component, biases the release lever to release the projection when the upper hinge member is rotated in the opposite direction and allows the inertial actuator to rotate by gravity if the predetermined deceleration forces are not present.

Title: Method and circuitry for controlling start-up characteristics of a magnetic amplifier control circuit
Inventor: MARUSIK C LEE
IPC: H02M1/36
Filed: 1995-04-27
Abstract: Start-up control circuit (152) regulates the output voltage (Vos) of a power supply circuit (150).  Magnetic amplifier control circuit (54) includes magnetic amplifier (42) and error detection circuitry (58, 68, and 70).  Start-up control circuit (152) includes sensing circuitry (176 and 184) for generating sensing signals in response to voltage levels (VCC and VEE) in error detection circuitry (58, 68, and 76).  Sensing signals indicate whether error detection circuitry (58, 68, and 76) voltage levels are sufficient to drive magnetic amplifier control circuit (54).  Reset circuitry (190 and 192, and 194) associates with the sensing circuitry (76 and 184) for initially resetting magnetic amplifier (42) to prohibit output voltage (VOS) from power supply circuit (150) when the sensing signals indicate that voltage levels are insufficient for error detection circuitry to drive magnetic amplifier control circuit (54).  Reset circuitry (190 192, and 194) further associates with reset control transistor (76) for controllably decreasing the reset of magnetic amplifier (42).  Reset circuitry (190, 192, and 194) further associates with magnetic amplifier control circuit (54) for shifting control of magnetic amplifier (42) to magnetic amplifier control circuit (54) as voltage levels increase sufficiently for the error detection circuitry (58, 68, 70 and 76) to drive magnetic amplifier control circuit (54).
