Title: Stress relief of metals
Inventor: HEBEL AUGUST G JR
IPC: C21D10/00
Filed: 1990-07-30
Granted: 1994-01-18
Abstract: Abstract of the Disclosure A method of stress relieving metal parts that includes the steps of applying mechanical cyclic vibration energy to a part over a test frequency range while monitoring the damping effects of energy flowing into the part as a function of frequency.    A  plurality  of  orders  of  harmonic  vibration absorption peaks are identified, each consisting of a plurality of vibration absorption resonant peaks, employing a vibration transducer having a response that is dampened to distinguish the harmonic peaks from the resonant peaks.  A sub-harmonic stress relief frequency is identified as a function of such frequency response and the composition of the part in question, and mechanical cyclic vibration energy is applied to the part for an extended time period at the sub-harmonic frequency so identified.

Title: Methods of and apparatus for coating optical fibers
Inventor: EDMONSTON DON R
IPC: C03C25/106
Filed: 1990-10-04
Granted: 1995-12-26
Abstract: An optical fiber (24), destined to receive a hermetic coating (32), is moved through a hermetic coating apparatus (30) wherein the fiber, entering the hermetic coating apparatus at a predetermined temperature, is caused to be engaged by a reactive gas. The reactive gas, reacting with the heated fiber, is effective to cause a layer of a hermetic material to be deposited adjacent to the outer surface of the fiber. A cross-flow purge gas is effective to prevent a resultant accumulation of a soot comprising reactive components of the reactive gas adjacent to portions of the hermetic coating apparatus which become heated by the fiber. Failure to prevent the accumulation of the soot may lead to fiber abrasions and reduced fiber strength.

Title: Ultrasonic cutting system for stock material
Inventor: BELL JEHU R
IPC: B26D1/10
Filed: 1991-08-21
Granted: 1996-05-07
Abstract: An ultrasonic cutting system for stock material temporarily bonds the stock material to an anvil incorporated in a processing table and cuts the stock material at a low angle with an ultrasonic cutting tool.  The ultrasonic cutting tool is mounted on a carriage assembly which traverses the width of the stock material.   The ultrasonic cutting tool  includes a cutting blade mechanically coupled thereto.   The cutting blade resonates in response to ultrasonic energy travelling axially therealong.  As the carriage assembly moves across the stock material, the stock material is first adhesively bonded or secured to the anvil by at least two rollers.   The rollers are mounted on the carriage assembly at a position slightly ahead of the cutting blade.  The rollers apply pressure  in  a  downward  direction  on  the  stock  material  to temporarily bond the material to the anvil and to prevent it from moving or vibrating during the cutting process.  As the carriage assembly moves across the stock material, the blade cuts through the stock material at a low angle, preferably at an angle of about 5° to 10° with respect to the horizontal.  After the blade has cut through the stock material, a trailing shoe, slidably moving along a channel guide formed in the anvil, removes the stock material from its adhesive bond with the anvil and allows the cut portion of the stock material to be removed for further assembly and processing into a tire.

Filed: 1990-11-30
Granted: 1996-06-04
Abstract: The  present  invention  provides  a  method  of preparing plasmids having the ability of expressing retroviral   genes   and/or   effecting   the  post-translational processing  of  the  encoded products, and  the  resultant  plasmid  and  the  expression products thereof.  A method of the present invention is to prepare a plasmid by insertion-linking a cDNA fragment containing at least the protease gene from among retroviral genes with a highly expressing gene or an expression vector for the direct expression of its gene products, thereby causing expression of the retroviral genes, and at the same time, to process said expression product itself with the protease in that expression product, thereby mass-producing the retroviral genes.   These retroviral genes comprise three kinds of core protein encoded by gag gene, and three kinds of enzymes encoded by pol gene, in the form of individual single mature or active proteins. Alternatively,  the method of the present invention is to prepare a plasmid in which a cDNA fragment containing HIV nef gene region is inserted into a highly expressing gene and an expression vector for the direct expression of its gene products, thereby mass-producing Nef protein which is the expression product of nef gene.

Filed: 1992-05-29
Granted: 2003-10-14
Abstract: The present invention relates to an electrically actuated and controlled auxiliary hydraulic system for controlling the flow of hydraulic fluid under pressure to mounted attachments on a skid steer loader.      In one embodiment, an electrically actuated auxiliary control valve is coupled to the front and rear mounted attachments through an electrically actuated diverter valve. In a second embodiment, a front and a rear auxiliary control valve is coupled to the front and rear mounted attachments. An operator can select between control of either the front or rear attachments by selectively actuating the forward, reverse and latch switches on the control handles. A mode control switch electrically coupled to an auxiliary mode control circuit allows the cyclical selection between the disable mode, the momentary made, and the latch mode.      In the disable mode, the actuation of the forward, reverse or latch switches has no effect. In the momentary mode, the operator controls the particular attachment during the time of the switch actuation. In the latch mode, the front attachment can be operated in a high pressure mode allowing extra power to be delivered to the front attachment.
