Title: Assays and treatments for autoimmune diseases
Inventor: HARLEY JOHN B
IPC: C07K16/00
Filed: 1991-01-31
Abstract: A specific method has been developed to identify the etiologic or immunogenic agent responsible for the production of autoantibodies characteristic of a particular disorder or immune response.  The antigen is first isolated, then divided into overlapping short amino acid sequences. The sequences having the greatest reactivity with the autoantibodies are identified and compared with all known amino acid sequences using the available computer data bases.  The protein having the maximum number of sequences homologous to the sequences of greatest reactivity with the autoantibodies is the likeliest candidate for the etiological agent. Applying this method, it has been determined that the etiological agent for the production of anti-Ro/SSA autoantibodies characteristic of numerous autoimmune diseases such as SLE appears to be a virus highly homologous to the Indiana strain of the vesicular stomatitis virus. Once the etiologic agent and antigenic sequences are known, it is possible to design assays and reagents for the diagnosis and treatment of patients having either the etiological agent and/or autoantibodies. An animal model has been developed for studying the mechanisms of, and screening compounds for the treatment or prevention of, the expression of these autoantibodies.

Title: Process for regenerating cologged filters
Inventor: TSUCHITANI MASATOSHI
IPC: B01D41/04
Filed: 1992-08-12
Abstract: Abstract PROCESS FOR REGENERATING CLOGGED FILTERS  When  preparing  carbon  artefacts  from  heavy  oils  of petroleum or coal origin, removal of undesirable components or recovery  of  desirable  components  from  raw  materials  or intermediates is usually required so as to improve the quality of the final products.  Such removal or recovery operation is conventionally done by filtration.  In the past, regeneration of   filters   clogged  with   solid  carbonaceous  materials inevitably formed by the filtration operations is difficult and troublesome procedures.  Herein disclosed is a simple and effective process for regenerating filters clogged with solid carboneceous materials,  characterized by treating the filter medium  in  an  aqueous  solution  of  hydrogen  peroxide  with heating and then optionally conducting ultrasonic washing in water or a solvent.  By this simple process, clogged filters can be  regenerated completely to show the same filtration performance as new filters.

Title: Winding apparatus for round bales
Inventor: BILLER BERND
IPC: A01F15/12
Filed: 1992-10-30
Abstract: Abstract The invention relates to an apparatus for winding plastic foil around a round bale consisting of hay, semi-dried grass or straw.   The apparatus comprises a frame and a winding table attached thereto and intended for receiving a round bale to be wound around.   The frame may be attached to a round bale press.   The round bale to be wound around is guided  to  a  loading bracket  via  a  roller  grid.    For transferring the round bale to the winding table, the latter is pivoted in the direction of the loading bracket.   For transfer purposes, both the loading bracket and the winding table  are  pivoted  until  the  winding  table  is  in  the horizontal winding position.  For unloading the finish-wound round bale, the winding table is tilted backwards, i.e. away from the loading bracket.   This design achieves a shorter unit and improves the transfer of the round bale on to the winding table into the winding position.

Abstract: Methods of and apparatus for detecting the leakage of fluids from containment vessels.  The tank is surrounded by or lined with a generally fluidtight envelope, and a vacuum is applied to hold the envelope against the tank and thereby control and limit to a very  small  volume  the  space  between the  primary containment,  be  it the vessel  or  liner,  and the envelope.  Fluids escaping form the containment vessel collect in that space.  Collected fluids are evacuat-ed; and fluid withdrawal information is processed, providing an advisory if a leak occurs or continues and/or information on the magnitude of the leak.  An indication of a possible leak can also be obtained by monitoring the pressure in the space between the containment vessel and the encapsulating envelope.  A trend-bucking change in that pressure  is  also  an indication of a possible leak.   Other installations make use of a second system to detect and evaluate leaks  into  the  installation  from the  surrounding environs.

Title: Pressurized vapor driven rotary engine
Inventor: SCHADECK MATHEW A
IPC: F01C1/077
Filed: 1992-01-31
Abstract: A rotary engine including a piston assembly (4, 6) having first and second adjacent hubs (66, 80). The hubs are rotatably mounted in a housing (2) about a common axis where they are coupled to two drive shafts (8, 10) that are concentrically arranged about the common axis. A first and second set of pistons (68, 82) extend radially outwardly from the first and second hubs, respectively.  Each piston head from the second set of piston heads is circumferentially spaced from a piston head of the first set to form a fuel expansion chamber (I-IV) therebetween. The distance between the rotational axis of the hubs and the outer peripheral surface of the piston heads is at least three times the distance between the outer peripheral surface of the piston assembly hubs and the outer periphery of the piston heads i.e., the radial depth of the expansion chambers. This construction permits the moment arm between the piston heads and the drive shafts and, thus, the torque developed by the engine to be relatively large as compared to typical reciprocating combustion engines.
