Abstract: ABSTRACT OF THE DISCLOSURE          A  fitting  (30) for use with soft tubing (40)  is disclosed.   The  fitting includes  a threaded female member (36) defining an aperture for insertion therethrough of the tubing.   The  fitting  further  includes  a male member  (32) defining a generally tubular portion (46) adapted for inser-tion into the end of the tubing.  The male member includes a radially extending  flange  for preventing the insertion of tubular  portion  into  the  tubing  beyond  a  predetermined distance.  The male member is further threaded for threading onto  the  female member. A sliding mandrel  (48)  is posi-tioned on the tubular portion for axial movement thereof.          The female member includes a generally inwardly projecting collar portion (64)  for engaging the outer surface of the tubing,  the  collar  portion  cooperating with  the  sliding mandrel to maintain the tubing in the fitting when a tensile pull is exerted on the tubing.

Abstract: ABSTRACT           Encapsulated liquid crystal material in a support medium illuminated from the viewing side or direction or through a louvered light guide from the back side will appear bright or white relative to background when in distorted alignment, e.g. in the absence of an electric field. Incident light impinging on the liquid crystal material is isotropically scattered into the support medium, and using the principle of total internal reflection and possibly also optical interference a relatively large part of the isotropically scattered light is directed back to illuminate the distorted liquid crystal material tending to brighten the same so that light it scatters back to the viewing direction out of the support medium causes the liquid crystal material to appear relatively light or bright as compared to the background where there is no liquid crystal material or where the liquid crystal material is in parallel alignment in field-on condition, i.e. aligned with respect to an electric field, and, thus, substantially transmissive. Original incident light where there is no liquid crystal material, that light which is isotropically scattered toward the back or non-viewing side of the display and within a certain cone or solid angle, and that light passing through aligned (field-on) liquid crystal material will tend not to be totally internally reflected; such light will pass through the support medium and may be absorbed by a remote black or colored material.

Title: Receiver systems for eliminating self-quieting  spurious responses
Inventor: VICTOR ALAN M
IPC: H04B1/26
Filed: 1984-05-15
Granted: 1987-05-12
Abstract: Abstract A multiple conversion superheterodyne receiver system includes a first frequency synthesizer capable of generating any one of a number of predetermined first local oscillator frequencies for mixing with an incoming signal to produce a first intermediate fre-quency.   A second frequency synthesizer selectively generates any one of two local oscillator frequencies corresponding to either high side or low side injec-tion to be mixed with first intermediate frequency producing an appropriate second intermediate frequen-cy. A frequency selecting circuit  is operatively coupled to the first and second frequency synthesizer for selecting an appropriate one of the first local oscillator  frequencies  to  tune  the  receiver  to  a desired channel and for selecting an appropriate one of the second local oscillator frequencies for avoid-ing receiver self-quieting spurious responses.
