Abstract: An aircraft comprising a fuselage and a vertical fin; a first set of airfoils having the form of a cylindrical wing extending outwardly and for-wardly from the said tail fin; a second set of airfoils in the form of wings extending outwardly and backwardly from a frontal section of the fuselage at a lower elevation than the first set of airfoils; and a third set of airfoils extending outwardly and backwardly from a frontal section of the fuselage at a lower elevation than the first set of airfoils and at a higher elevation than the second set of airfoils. The second and third sets of wings extend outwardly and connect at their tips with the first set of wings by means of streamlined surfaces in order to minimize induced air drag. The first and second pairs of wings along with the fuselage present a double triangle or diamond shape in the top plan view and a partial circular shape in the front elevational view. The third pair of wings presents similar shapes with respect to the first airfoils and fuselage in the top plan and front elevational views. Additionally, a unique wing structure is disclosed for the cylindrical wing where the upper and lower cambers vary along the span of the wing to enhance lift and vertical stability such that the cylindrical wing acts as a lifting as well as a directional component. Finally, a unique separation process of the fuselage and wing structures affords a safe and un-powered descent of the aircraft components in the event of an aborted flight.

Abstract: GEL-BASED THERAPY MEMBER AND METHOD            Abstract of the Disclosure Improved  therapy  members  useful  for treating of sprains, muscle aches, orthopedic and skin injuries such as burns and other wounds are provided  which  make  use  of  a  pliable,  self-sustaining,  moisture  sorbing  gel  including humectant such as glycerin entrapped within a synthetic resin polymer matrix (e.g., a matrix containing  acrylic  acid  or  acrylamide  monomer moieties).  In one preferred embodiment, a body of the gel is encased within heat and moisture-permeable stretch fabric, and securing ties or the like are provided to permit the composite to be conformed to a body part and held in place.   In use, such therapy wraps are either heated (as in a microwave oven) or refrigerated, so as to provide appropriate thermal treatment; it has been found that the preferred gel of the invention retains its pliability and other physical properties over a very broad temperature range, such as -20 to 350° F., and therefore the wraps of the invention can be used in many treatment contexts.   It has also been discovered that the gel material can be applied directly to injured skin to in effect create a temporary skin with ideal air perme-ability.  Furthermore, the moisture absorbing and desorbing properties of the gel create a moisture equilibrium between the gel, damaged skin and the atmosphere, thus promoting rapid healing.

Granted: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for multi-stage cementing of a well casing which permits rotation of the upper casing string independent from the lower string during the second or subsequent stage of cementation in order to ensure full displacement of any borehole fluids.   The apparatus is readily  connected  to  conventional  casing  strings  and connects the upper and lower strings.  The swivel includes a lower liner portion which is secured to the lower casing string and an upper liner portion which is connected to the upper string.  These liner portions are telescopically engaged  such  that  the  upper  liner  portion  can  be vertically displaced relative to the lower liner portion. Both liner portions include longitudinal  splines which engage to permit simultaneous rotation of the full string yet  can  be  disengaged  by  displacing  the  upper  liner portion in order to provide independent rotation of the upper  string.   The  device  is  utilized  to  rotatively disengage the upper string from the lower string once the first stage of cementation is completed.  Upon displacing the first stage of cement through rotation of the full string,  the  intermediate  multi-stage  cement  valve  is opened  and  the  splines  of  the  swivel  mechanism  are disengaged.  Thereafter, the second stage of cement slurry is pumped through the ports of the multi-stage valve while the upper string is rotated in order to provide complete displacement of the cement.

Filed: 1988-03-01
Granted: 1991-12-17
Abstract: GLASS FIBER BULK STRAND ROVING AND METHOD AND APPARATUS FOR THE MANUFACTURE THEREOF       ABSTRACT OF THE DISCLOSURE The present invention describes a method and apparatus for producing a bulk strand roving comprising a multiplicity of strands with axially extending loops interengaged and entangled with cross-axially extending loops.  The roving of the present invention is made by a process that uses a finger wheel (32) to form axially extending loops in strands and a spinner (36) downstream of the finger wheel.  The looped strands from the finger wheel pass through a relatively unrestricted passage in the spinner which imparts a twist to such looped strands, and then through a relatively restricted outlet orifice (42) that is downstream of the outlet of the spinner.  A back-up or puddling of the looped strands occurs in the spinner near the outlet thereof, due to the axial length of the loops in the strands and the restriction in the outlet of the spinner in the form of the outlet orifice, and this back-up or puddling of the looped strands in the spinner, in conjunction with the spinning thereof, results in the formation of the cross-axial loops in the axial loops of the strands.
