Title: Stabilized sulfur-containing resins, such as  polyphenylene sulfide and method of producing the  same
Inventor: QUELLA FERDINAND
IPC: C08L77/00

Granted: 1987-10-20
Abstract: ABSTRACT OF THE DISCLOSURE Sulfur- containing polymers, such as polyphenylene sulfide, are stabilized from releasing sulfur--containing exhaust gases by adding an additive polymer having at least one reactive radical selected from the group consisting of amino radicals, amido radicals, imido radicals, and keto radicals therein, and which is of approximate the same thermal stability as the sulfur- containing polymer, to such sulfur- containing polymer.  In other embodiments of the invention, sulfur- stabilization is also achieved by incorporating suitable fundamental building blocks of the additive polymer into the sulfur- containing polymer chain in the form of reactive monomers. Further, in other embodiments, additive polymers or oligomers (so-called telecheles) having reactive radicals at their ends can be introduced into the sulfur- containing polymer chain as copolymers.  In addition, low molecular weight compounds having high boiling points and having structures similar to the fundamental building blocks of the sulfur- containing polymers are also effective for stabilizing such polymers.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention is an improvement over my U.S. Patent No. 4,326,577 issued April 27, 1982 for a window screen arrange-ment comprising a novel roller combination for winding and un-winding the screen or shade element and at the same time posi-tioning of the entire screen assembly in a desired position vertically on a window to provide partial screening in any part of the window while at the same time permitting additional screen-ing provided by the operation of the screen upon a roller.  The method of supporting the screen in the window opening comprises a novel arrangement of cords for support and positioning which permit the foregoing without the use of pulleys, springs, counter-weights, hooks, clamps or other positioning devices to hold the screen assembly in any given location by permitting its roller features to function.  The arrangement used here entails the use of only two instead of four cords as in my previous in-vention and by means of the novel continuous arrangement of the cords it simplifies the construction and permits positioning of the rollers at an angle to the window frame from the hori-zontal.  I also provide a novel method of fastening the screen upon the rollers.

Abstract: Abstract Method and apparatus are disclosed for indicating and correcting misregister of plural overlapping images produced by a multicolor press.  A register indicia (Fig. 3) is used comprising two overlapping sets of parallel lines (R and C), each set being formed in a known position relative to a corresponding one of the images whereby the positional relationship between the sets of lines varies with the positional relationship of the images.  The extent of overlap of the sets of lines is dependent upon displacement of the sets of lines in a direction transverse to the lines, whereby the percentage of nonprint area in the register indicia is dependent upon register of the overlapping images in that transverse direction.  The percentage of nonprint area is detected by illuminating the register indicia area and measuring the extent to which the area reflects the light.  The resulting signal is used to control the register adjustment mechanisms of the multicolor press.

Abstract: Abstract of Disclosure A relay with a contact making independent from environ-mental conditions with two hermetically sealed contact pills is described.  Each contact pill comprises a switching-over contact and a diaphragm made of electrically and magnetically conducting material which diaphragm is the movable member adhering on corresponding contact poles due to the magnetic flux caused by a permanent magnet and flowing through the core of a drive coil.  To change the contact condition of the relay it is sufficient to produce a current pulse through the drive coil causing a control flux of a magnitude which exceeds that of the permanent magnet flux by a small amount only because the two fluxes add their strength when the change-over operation is initiated.  Due to this adding the needed drive power is so small that a direct driving by TTL-circuits is possible.  By other arrangements of the permanent magnet within the magnetic circuit monostable relays can also be realized.

Abstract: ABSTRACT OF THE DISCLOSURE      A locking mechanism for securing an inner member of a well assembly to the bore of a support or outer member has  features  that  prevent  any  movement  of  the  inner member due to a force acting along the axis of the bore.          The  locking mechanism  includes  a  plurality  of  wicker grooves formed in a sidewall of the bore transverse to the axis of the bore.  Reacting grooves are formed on an cuter wall of the inner member perpendicular to the axis of the bore.  Slips are spaced around the outer wall of the  inner  member  between  the  inner  member  and  the sidewall of the bore.  The slips each have wicker grooves on the exterior and reacting grooves on the interior.          The locking mechanism includes an expansion device for moving the slips from the contracted position in which the wickers are nonengaging to an expanded position in which  the  wickers  engage  each  other. The  reacting grooves of the inner member each have an inclined surface facing generally outwardly and in the direction of the force.  The force acting on the inner member causes the reacting grooves to transmit a resultant force to the slips to push more tightly against the bore.

Abstract: ABSTRACT OF THE DISCLOSURE BLADE CONTAINMENT STRUCTURE            A blade containment structure employs a two-layer honeycomb region radially outward of a fan blade rub strip.  The two layers are separated by a septum and each layer contributes independently to strength and stiffness of the structure.  A Kevlar blanket radially outward of the honeycomb region retains blade fragments which may be broken loose by ingestion of large objects such as, for example, birds.  The radially inner honeycomb region is deep enough to position the septum out of the orbit of blade tips in an engine made unbalanced by loss of one or more fan blades.  The septum and outer honeycomb region retains sufficient strength in the structure supporting forward components.

Abstract: NHL-KFJ-09 Canada PROCESS AND APPARATUS FOR WASTE WATER PURIFICATION                 ABSTRACT OF THE DISCLOSURE      The invention provides a process and an apparatus for effecting that process in which waste water to be cleaned is finely divided into a current of entrainment gas and evaporated. The water vapor formed is superheated, so that the impurities occur as a solid residue and can be collected.  The heat of the purified and compressed mixture of entrainment gas and water vapor is used to superheat the water vapor in the current of entrainment gas.      An optimal separation between water and the substances contaminating it which cannot be evaporated is accomplished with a low expenditure of energy by introducing the water into a current of inert entrainment gas and by heating the mixture of entrainment gas and water vapor thereby formed, before the separation of the solid particles, in the heat exchange with the purified and compressed mixture of entrainment gas and water vapor by cooling it to below the saturation or dew point temperature.
