Title: Method and apparatus for continuous contact of supercritical fluid with particulate solids
IPC: A23F5/20
Filed: 1990-01-26
Abstract: Method and apparatus for contacting particulate 
solid matter with a fluid in a pressure vessel (10) through which 
the fluid continuously moves at high, supercritical, 
pressure while the particulate solid matter is periodically 
moved via isolatable pressurizable vessels (12,16) which are 
periodically pressurized and depressurized to and from the 
supercritical pressure to facilitate periodic movement of 
the particulate solids between the pressure vessel and the 
isolatable pressurizable vessels. A supply of the fluid is 
maintained at an intermediate pressure at which the fluid 
exists in both the liquid and gaseous states. The 
pressurizable vessels are raised to supercritical pressure 
by first using intermediate pressure fluid in the gaseous 
state and then in the liquid state, followed by introducing 
fluid at the supercritical pressure. The vessels are de­
pressurized by first venting and then pumping to the 
intermediate pressure fluid supply.

Title: Mechanical connection for polarization-maintaining optical fiber and methods of making
IPC: G02B6/024
Filed: 1990-02-02
Abstract: A mechanical connection arrangement for two polarization-maintaining 
optical fibers (20-20) includes two ferrules (40-40). Each of the optical fibers to be 
connected includes an outer cladding layer (23) having a hybrid cross section 
transverse to a longitudinal axis of the fiber. The hybrid cross section is defined by 
two parallel sides and by two generally arcuate end portions. One of the polarization 
axes of the fiber is parallel to the parallel sides of the fiber. The ferrules were 
adjacent portions in a length (110) of stock material and are positioned in support 
means such that end faces of the ferrules which were contiguous to each other prior 
to the ferrules being separated from the length of material are adjacent to each other 
in the connection arrangement. Each ferrule prior to separation has a tab (126) 
associated therewith such that the tab of the adjacent portions are aligned 
longitudinally. An end portion of each optical fiber to be connected is disposed in a 
substantially rectangular passageway (122) formed through a ferrule and terminating 
in an end face. Each tab is normal to a long side of the rectangular passageway of 
the associated ferrule and hence is normal to the parallel sides of the outer cladding 
layer cross section of the optical fiber disposed therein. The ferrules are held to 
cause the tabs to be aligned longitudinally thereby causing the angular orientation of 
the polarization axes and the cores of the connected fibers to be aligned.

Title: Planar array waveguide antenna with l-shaped series/series coupling slots
IPC: H01P1/04
Filed: 1990-12-11
Abstract: An array antenna which includes a first waveguide 12 
coupled to a second waveguide 20 by an L-shaped 
coupling slot 30. The slot 30 has a first portion 32 
orthogonal to a second portion 34 thereof thereby 
providing the unique L-shape. In a specific embodiment, 
the slot 30 is located with the first portion 32 along 
the centerline and longitudinal axis of the first 
waveguide 12 and the second portion 34 along the 
centerline and longitudinal axis of the second waveguide 
20.  
     The folded short, as well as the tapered section of 
prior designs can be eliminated by use of the L-shaped 
coupling slot of the present invention in the first and 
last positions of the coupling slot because a short can 
be placed at the L-shaped slot. Hence, the L-shaped 
coupling slot of the present invention provides a more 
compact planar antenna than that afforded by conventional 
designs.
