Title: Microporous materials incorporating a nucleating agent and methods for making same
Inventor: MROZINSKI JAMES S
IPC: B29C48/08
Filed: 1987-10-22
Granted: 1993-06-01
Abstract: Abstract of The Disclosure The present invention relates to microporous materials incorporating a nucleating agent and methods for making the same.  The method comprises the steps of melt blending a crystallizable thermoplastic polymer with a nucleating agent which is capable of inducing subsequent crystallization of the thermoplastic polymer and with a compound which is miscible with the thermoplastic polymer at the melting temperature of the polymer but phase separates on cooling at or below the crystallization temperature of the polymer, forming a shaped article of the melt blend, cooling the shaped article to a temperature at which the nucleating agent induces the thermoplastic polymer to crystallize so as to cause phase separation to occur between the thermoplastic polymer and the compound, thereby providing an article comprising an aggregate of a first phase comprising particles of crystallized thermoplastic polymer in a second phase of the compound, and stretching the article in at least one direction to provide a network of interconnected micropores throughout. Preferably, the compound is removed either before or after stretching.  The use of a nucleating agent in accordance with the present invention provides for the manufacture of a wide variety of microporous materials heretofore not possible having a wide range of porosity and other physical characteristics.

Abstract: Abstract of the Disclosure An electrohydraulic servo system which includes an actuator having a cylinder and a piston variably positioned therewithin, a servo valve responsive to valve control signals for coupling the actuator to a source of hydraulic fluid, and control electronics responsive to piston position for generating the valve control signals.  A variable frequency rf generator is coupled through associated directional couplers to a pair of antennas which are positioned within the actuator cylinder and physically spaced from each other in the direction of piston motion by an odd multiple of quarter-wavelengths at a nominal generator output frequency.   A phase detector receives the reflected signal outputs from the directional couplers, and provides an output through an integrator to the frequency control output of the generator to automatically compensate frequency of the rf energy radiated into the cylinder and thereby maintain electrical quarter-wavelength spacing between the antennas against variations in dielectric properties of the hydraulic fluid due to changes in fluid temperature, etc.  A second phase detector is coupled to the generator and one antenna to generate a piston position signal.

Granted: 1992-04-28
Abstract: ABSTRACT OF THE DISCLOSURE    In a tennis racket whose frame and handle shaft are integrally made of fiber reinforced plastics and the frame defines a strung surface, the frame is so designed that its first thickness "t" in a direction of the strung surface is substantially uniform around the circumference of the frame and its second thickness "T" in a direction perpendicular to the strung surface is gradually varied.          The second thickness is maximum at side sections of the frame interposing a sweet spot in the strung surface and is minimum at the top and bottom portions of the frame in such a manner that the maximum thickness is thicker in the range from 35 % to 60 % than the minimum thickness, which increases a weight per unit length of the frame toward the side sections.

Abstract: ABSTRACT OF THE DISCLOSURE          An achromatic scanning system subjects an incoming beam of light to reflection off four successive mirrors.  The mirrors at the input and output are pre-ferably plane mirrors and are referred to as the scanning mirrors.  They are movable and provide the desired beam displacement when appropriately driven. They face away generally from each other and are rotatable about respec-tive axes.  Each axis lies in the plane of its respective mirror and the two axes are non-parallel (preferably perpendicular) to each other.  The two intermediate mirrors are concave mirrors that face each other and define an afocal assembly that transfers the light reflected from the first scanning mirror to the second scanning mirror.

Abstract: Abstract of Disclosure The present invention relates to the improvement of decoking a residual oil delayed coker and apparatus thereof. When decoking,  the roller of the   flexible pipe winch (3) is rotated to vertically ascend or des-cend the decoking flexible pipe  (6) in   the   coker wherein the high pressure water rotates the turbine blades of the turbine-reductor (7) which brings the drilling and cutting combination unit (8) into rotation so as to drill a through hole in the coke accumulation and then conduct decoking operation. The drilling and cutting combination unit (8)   is  equipped  with  a pressure control unit so that the switchover of   the drilling and cutting operations can be automatically performed.  The present invention has eliminated the use of derrick, saved a significant quantity of steel and investment,  decreased the number of equippments, made the operation easier, needed less time for de-coking and therefore further enhanced the   decoking efficiency.

Abstract: Abstract of the Disclosure An improved hammerbank in a dot matrix line printer has two different sets of staggered apertures therein along the length thereof for drawing pressurized air at the outside of the hammerbank therein to provide turbulent, high velocity cooling air in the region below the magnetic coils of the magnetic hammer actuators.  The cooling air is confined to passage over the magnetic coils by enlarged flanges on the coil bobbins which form an air dam.  The air dam discourages escape of the cooling air through spaces between the hammer springs.          Magnetic  interaction  between  adjacent  magnetic hammer actuators is minimized due to the absence of common magnetic materials extending therebetween, except for the permanent magnets  which  hold  the  hammer  springs  in  the retracted position.  The permanent magnets are common to a plurality of the magnetic hammer actuators and by physically extending therebetween serve to prevent substantial leakage flux from occurring.   The hammerbank is mounted for reciprocating motion by a single, intergrally formed, hollow shaft which extends through the entire length of the hammerbank and beyond the opposite ends thereof.          The hammer springs are mounted by screws driven into endless screw holes which  terminate at  the cooling apertures within the hammerbank so as to accommodate relatively long screws and at the same time expel debris that might otherwise accumulate within the screw holes.      The upper portions of a cover assembly at the front of the hammerbank are held in fixed relation by magnetic clip assemblies mounted  thereon  and  having  permanent magnets attached thereto in a manner which permits precision grinding of the clip assemblies.

Title: Method of injection molding articles of thermoplastic materials and apparatus for carrying out the method
Inventor: ECKARDT HELMUT
IPC: B29C45/57
Filed: 1988-10-07
Granted: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE     A method and an apparatus of injection molding articles of thermoplastic material.   The method includes  initially forcing molten plastics material into an injection mold in an amount sufficient for forming the article.   Subsequently, a flowable medium is forced into the injection mold with a pressure which distributes the plastics material uniformly over the surface of the mold cavity of the injection mold so as to form a hollow body.  The hollow body is then cooled while the pressure of the medium is maintained.  Finally, the pressure of the medium is released and the molded article is removed from the injection mold.  The pressure of the medium in the mold cavity is controlled and/or varied at least temporarily until the plastics material has cooled.   The apparatus for carrying out the method includes a pressure reservoir for the medium which is connectible to the injection mold through lines.  The lines include control and/or regulating elements.
