Abstract: 6/27/89:Fl TITLE OF THE INVENTION   MACROLIDE INTERMEDIATES            ABSTRACT OF THE DISCLOSURE         A process for the conversion of FR-506 (I,R = allyl;1) to FK-525 (XV) and analogous 23-membered ring macrolides differing in the C.1-N.7 segment of the molecule (e.g. XVI) and is also applicable to the analogs FK-523 (XVII) and FK-520 (XVIII).  The overall process consists of three stages: (a) initial degradation of the primary macrolide to an acyclic fragment containing a selectively protected C.10-C.34 framework with a protected aldehyde function at C.10 and a free hydroxyl function at C.26, (b) reacylation of the C.26 hydroxyl function with an appropriately N-protected alpha-amino acid moiety, and (c) reintroduction of the C.8 and C.9 carbons followed by regeneration of the FK-macrolide system.

Title: Extension support unit
Inventor: ATSUKAWA MASUMI
IPC: E04H12/18
Filed: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE    The extensible support pole unit having a simple structure including a plurality of shaped members, e.g., cylindrical bodies, band-like plates having, e.g., an arched cross-sectional shape, a band-like plate feed mechanism, and a driving device.  The support pole is extended to stand or retracted by only paying out or winding up the band-like plates.  The support pole can therefore be extended to a length freely selected, and it is possible to freely set a large extension ratio by selecting the length of each cylindrical body and the number of cylindrical bodies.  The band-like plates have, for example, an arched cross-sectional shape and have properties such as to be strong against the vertical load as compared with flat plates.  The band-like plates are retained in the guide slits or guide holes formed in the partition members disposed in the cylindrical bodies to further improving the above properties.  With respect to the lateral load, the material, the diameter, the thickness of each cylindrical body, and the area of the connection portion of each cylindrical body are selected to maintain a sufficient strength.  The influence of the lateral load upon the band-like plates is therefore negligible.

Title: Wall mounted folding carrier
Inventor: ALLEN CHRISTOPHER B
IPC: B62H3/12
Filed: 1991-08-08
Abstract: ABSTRACT A folding carrier that is mountable upon a generally planar member includes a rotatably connected frame and carrying member. The frame is a substantially U-shaped member having a pair of legs and a back, each leg having a stop.  The carrying member, which is also a U-shaped member, is constrained for limited rotational movement relative to the frame between a carrying position and a stored position.  In its stored position, the carrying member is in a side-by-side relationship with the frame and inclined backwardly toward it.  When in its extended position, the carrying member is substantially perpendicular to the planar member upon which the carrier is mounted.  The carrying member bears against the stops of the frame to prevent further rotation beyond the preferred carrying position. Frictional elements that are mounted on the frame and carrying member engage the generally planar member and prevent unwanted movement of the carrier.

Title: Filtering apparatus
Inventor: HALDIPUR GAURANG BALCHANDRA
IPC: B01D46/24
Filed: 1991-10-21
Abstract: 56,211 ABSTRACT OF THE DISCLOSURE A vertical vessel having an upper inlet and a lower outlet enclosures separated by a main horizontal tube sheet.  The inlet enclosure receives the flue gas stream which contains particulate from a boiler of a power system and the outlet enclosure supplies gas from which the parti-culate has been removed to the turbines.  The gas in the inlet enclosure is at high temperature and high pressure. To separate the particulate, the inlet enclosure contains a plurality of particulate-removing clusters, each having a plurality Or filter units.  Each filter unit includes a filter chamber defined by a plate and a perforated auxiliary tube sheet with filter rods suspended from each tube sheet and a tube connected to each chamber for passing cleaned gas to the outlet enclosure.  The clusters are suspended from the main tube sheet by a pipe with their filter units extend-ing vertically in succession and the tubes passing through the tube sheet and opening in the outlet enclosure.  Each cluster is formed into a physically integrated structure by pipes connecting the auxiliary tube sheet of each upper chamber in the succession to the plate of the next lower chamber in the succession.  The air stream containing the particulate is circulated about the outside surfaces of the filter rods and the particulate is absorbed in the pores of the rods.  Pulses to clean the rods are passed through their inner holes through tubes free of bends which are aligned with the tubes that pass the clean gas.  Each filter rod is mounted in an assembly including a housing for the head of the filter rod.  Gaskets for accommodating the filter rod to the conditions within the vessel are interposed between the housing and the head of the filter rod.

Abstract: A urea production process in which the urea solution produced in the reaction zone is treated in sequence with a first thermal decomposer at the same pressure as the reaction, to decompose part of the residual ammonium carbamate into its components, then with an adiabatic stripper in which the free ammonia is stripped with CO2 operating at a pressure which is 1-7 MPa less than the synthesis pressure, then with two further carbamate thermal decomposition stages at decreasing pressures. The gaseous products obtained from those stages at pressures less than the synthesis pressure are mixed with the recycle solutions from the downstream stages, condensed by heat transfer against said downstream stages, and then recycled to the reaction as liquid.
