Title: Machine for slitting metal sheet
Inventor: VOGES KENNETH
IPC: B23D35/00
Filed: 1987-12-04
Granted: 1991-10-08
Abstract: ABSTRACT A machine for slitting metal sheet has a bridge-type frame provided with upper and lower beams supported on posts.  In the space between the two beams are upper and lower powered arbors and also upper and lower storage arbors which align respectively with the upper and lower powered arbors.  Each powered arbor supports and turns several knives which are mounted on hubs along those arbors, and these knives when not needed may be moved, along with their hubs, onto the aligned storage arbors.  Each knife is captured in a carriage which moves along one of the beams and contains back-up rollers which bear against the knife to prevent its arbor from deflecting under the spreading force exerted by the metal sheet as it is slit.  The hubs have a wide stance, and accordingly the knives on them do not acquire a wobble when the hubs are secured on their respective arbors; yet notwithstanding the wide stance, the knives may be brought quite close together.  The storage arbors normally support the ends of the powered arbors, but may be withdrawn to remove the knives from the arbors.  The knives are positioned through a lead screw which drives a carriage having stops against which knives on the upper and lower arbors are moved.  The carriage may also be provided with fing-ers that actually capture the knives of a pair and move them to the correct position.

Abstract: Abstract A corrosion resistant aluminum article is described. It includes a main body portion formed of an aluminum alloy containing no more than 0.4% iron, no more than 0.15% silicon, from about 0.1% to about 0.6% copper and from about 0.7% to about 1.5% manganese.  The corrosion resistance is provided by a silicon-rich band of dense precipitate formed in the alloy adjacent at least one face thereof.  This band has a thickness of about 20-50 µm and there is substantially less manganese in solid solution in the band than in the alloy outside the band.  To form the band, a silicon-containing layer is applied to a surface of the alloy body to be protected and the composite thus formed is heat treated at a temperature of at least 550°C.

Title: Method for restraining response of a structure to outside disturbances and apparatus therefor
Inventor: SATO TAKANORI
IPC: F16F7/104
Filed: 1988-04-28
Granted: 1992-10-13
Abstract: Abstract The present invention concerns apparatus for restraining vibration of a structure having at least one natural mode of vibration.  The apparatus comprises an enclosure, a main weight, a resilient member, a viscous liquid, and an adjustment device.          The enclosure defines an inner space therein and the main weight, has a mass and is enclosed in the enclosure.   The resilient member connects the weight to the enclosure and exerts on the weight,  a  restoring  force  proportional  to  the  relative displacement of the weight with respect to the enclosure.  The viscous liquid is retained in the inner space and has a viscosity which  provides  to  the  weight,  a  damping  force  which  is proportional to a relative velocity of the weight with respect to the enclosure.  The resilience of the resilient member and the mass of the main weight provide the apparatus with at least one natural frequency of vibration   The adjustment device provides the capability of adjusting resilience of the resilient member and/or the mass of the weight, in order to adjust the natural frequency of the apparatus.  In order to restrain the vibration of the  structure,  the apparatus has  at least one natural frequency of vibration which corresponds to at least one natural mode of vibration in the structure.

Title: Pressure swing adsorption apparatus and process for recovery of oil-soluble vapors
Inventor: ROBBINS LANNY A
IPC: B01D53/04
Filed: 1989-06-09
Granted: 1993-07-13
Abstract: ABSTRACT          In a pressure swing adsorption system used to recover an oil-soluble solvent, monomer or hydrocarbon vapor such as 1,1,1-trichloroethane or styrene from a gaseous stream such as air, an oil-sealed vacuum pump may be used without substantial absorption of vapor into the oil if the oil in the pump is heated to a temperature substantially above the dew point of vapor in the gas stream leaving the pump.   Prior to this invention, oil-sealed vacuum pumps cannot be used to recover oil-soluble compounds because the vapor dissolves in the oil as the desorbed vapor and backpurge gas pass through the pumps.  The thinning of the oil hurts the lubrication and seal within the pump and floods the pump.     C-36,529
