Abstract: AQUEOUS PROCESS FOR PREPARING WATER-RESISTANT      COATINGS OF HYDROPHOBIC COPOLYMERS   MADE FROM HYDROPHILIC MONOMERS                      Abstract An aqueous process is described for preparing water-resistant coatings of hydrophobic copolymers of a predetermined composition.  The hydrophobic copolymers are made from hydrophilic comonomers such as a vinyl lactam and a polymerizable carboxylic acid.  The hydrophobic copolymers are rendered water soluble with a volatile neutralizing agent, such as ammonium hydroxide, then coated onto a substrate and heated to provide the water-resistant coating, and, if desired, redissolved in an aqueous alkaline solution.

Abstract: Abstract of the Disclosure This invention is directed toward reducing substantially the loss incurred when two optical fibers of different mode diameters are coupled together. In this invention, the coupling of one fiber to that of another where the fibers are of different mode diameters is not with a tapered fusion, core-to-core splice, but with an evanescent field fiber coupler. Briefly, to achieve amplification of a weak optical signal, an amplifying fiber is inserted into the system at one or a plurality oflocations. More specifically, at a desired location, the transmission fiber is severed to provide two sections and the severed sections are transversely coupled to theamplifying fiber. The weak signal from the first section of the transmission fiber is coupled into the amplifying fiber via a first evanescent field type of fiber coupler, and the amplified signal is coupled from the amplifying fiber to the second section of the transmission fiber via a second evanescent field type of fiber coupler. The first evanescent field type of fiber coupler is designed w couple substantially all of the signal energy from the first section of the transmission fiber to the amplifying fiber and to couple substantially none of the laser diode pump signal or energy from the amplifying fiber to the transmission fiber. The second evanescent field type of fiber coupler is designed to couple substantially all of the signal energy in the amplifying fiber to the transmitting fiber and substantially no laser diode pump energy is transferred from the amplifying fiber to the transmission fiber. Either or both cut ends of the transmission fiber can be coupled to monitor devices to detect and determine the value of the signal being coupled into an/or out of the amplifyingfiber w control, for example, the gain of the amplifying fiber.

Abstract: A vacuum-type sewage collecting apparatus arranged in such a manner that sewage discharged from the houses or facilities is once accumulated in a cesspool and the sewage accumulated in the cesspool is then collected in a predetermined portion through a vacuum valve and a vacuum sewage pipe the inner pressure of which has been made to be a negative pressure is disclosed. The vacuum valve being operated by negative pressure taken up from a vacuum source and supplied to the vacuum valve via a connecting pipe. The negative pressure for operating the vacuum valve is taken up from a vacuum sewage pipe portion which is elevated at a level higher than that of the vacuum valve in the down stream of the vacuum valve. Instead, the negative pressure may be directly taken up from an accumulating tank the inner pressure of which has been made to be a negative pressure by a vacuum pump, a pipe which establishes a connection between the accumulating tank and the vacuum pump or a tank connected to the pipe connecting between the accumulating tank and the vacuum pump. In this way, a high negative pressure can be supplied to the vacuum valve to effectively and completely open the vacuum valve to thereby perform efficient discharge of the sewage through the same valve.

Abstract: An electronic circuit provides a linear output from an amplitude modulated transmission device such as a semiconductor laser which has inherent distortion. The distortion of the nonlinear device is compensated by applying a predistorted signal equal in magnitude and opposite in sign to the distortion introduced by the nonlinear device.  The input signal is split into two paths with primary part of the signal applied directly to the device, with a time delay to compensate for  delays  in  the  secondary  path.    A  distortion generator   in   the   secondary   path   generates intermodulation signals,  the amplitude of which is adjusted to match the amplitude of the distortion of the nonlinear device.   A tilt adjustment is made to compensate  the  amplitude  of  the predistortion  for frequency  dependence  of  the  amplitude  of  the distortion.  A adjustment of the predistortion signal is also included so that phase of the distortion signal generated  is  in  proper  phase  relation  with  the distortion  inherent  in  the  nonlinear  device.    A push-push amplifier is used as a distortion generator, with bias current unbalanced to produce net odd order intermodulation  products  as  well  as  even  order intermodulation   products   of   the   fundamental frequencies.

Abstract: 55,507 ABSTRACT              Apparatus for lifting and applying torque to an object is disclosed.  The apparatus comprises a releasable spring counterbalance which resiliently connects a drive for engaging applying torque to the object to a means for lifting an object, such as a crane.  Preferably, a body portion connects the drive and a means for supporting the object.  A spring counterbalance reduces the force due to the weight of the object which bears upon the threads when the object is lifted into a position to be torqued.  After the threads are initially engaged, the counterbalance is removed and torque applied to the drive means.  Torque is transferred through the body portion to the object.  Thus, problems associated with the handling of large parts and initially engaging threaded connections are substantially reduced, since the initial engagement takes place under conditions of reduced force.  The apparatus of the present invention creates a "soft" or "floating" connection between the material handling apparatus and the part being assembled.  In a preferred embodiment, apparatus for installing a throttle valve bushing in a throttle valve bonnet is disclosed.  Methods of assembling machine parts are also disclosed.

Inventor: SORENSEN JOSEPH A
IPC: B25B1/02
Filed: 1991-02-14
Abstract: The present invention is directed to a bar clamp especially suitable for rapid and precise closure against a workpiece.  The clamp includes a fixed jaw and a movable jaw opposing the fixed jaw.  The movable jaw connects at one end to a slide bar which is movable to bring the movable jaw toward and away from the fixed jaw.  A one-way drive controlled by a trigger handle grip, realeasably engages the slide bar and advances the movable jaw toward the fixed jaw. Return motion of the movable jaw away from the fixed jaw is accomplished manually when the one-way drive is disengaged. A first braking lever which is biased to bind against the slide bar prevents reverse motion of the movable jaw away from the fixed jaw, except when the first lever is disengaged from the slide bar.  For return motion of the jaw the one-way drive and the first braking lever are disengaged.  The trigger handle advances the slide bar by driving a second lever which binds against a surface of the slide bar and moves the rod as the second lever moves toward the fixed jaw. The second lever is returned by spring force to its original position after each stroke of the trigger handle, the second lever sliding over the bar surface during its return motion.
