Patent NO-178647-C (NO)
Inventor: LEVINE ROBERT A
IPC: G01N33/50
Filed: 1990-04-18
Abstract: A patient's blood sample is incubated with an antigen and tested for lymphocyte response, ie. an activation of lymphocytes and/or a conversion of lymphocytes to lymphoblasts, which indicates prior exposure of the patient to the antigen. A positive response indicates the presence of prior exposure to prior diseases or clinical conditions such as parasitic diseases, tuberculosis, salmonellosis, gonorrhea, fungal infections, rickettsial infections, Lyme disease or allergens. Whole blood from the patient is incubated with the antigen of the disease or condition for which the patient is being tested. After a suitable time, a fluorescent dye or colorant which has an affinity for a discriminant characteristic of the activated lymphocytes or lymphoblasts, such as: intracellular calcium; surface activation antigens such as transferrin receptor; HLA-Dr; Leu-23; and the like. The incubated blood is then drawn into a transparent tube containing a float which concentrates the buffy coat constituent layers upon centrifugation of the blood sample. The concentrated lymphocyte layer is then examined for fluorescence or coloration which is indicative of the presence of the activated lymphocytes or lymphoblasts, and their concentration. The fluorescence or coloration can be qualified and/or quantified by a reader instrument.

Title: Plug-in module as a component of a toy building block system
Inventor: LARWS PETER
IPC: A63H33/06
Filed: 1991-12-23
Granted: 1999-10-12
Abstract: A plug-in module one side of which incorporates four spring leaves that can be deflected slightly outwards and which are arranged on one side in a tulip shape and which, on the other five sides surfaces, can be snapped onto a similarly constructed plug-in module. The side surfaces incorporate ridges which can be either continuous or segmented. On their inner sides, the spring leaves are provided with corresponding connecting elements which snap behind the ridges described above. The connection between two plug-in modules is effected first by a slight outward deflection of the spring blades from their rest position and by them subsequently snapping into position behind the ridges. The plug-in modules have the advantage that even after a long time and frequent use, they can still be connected to each other easily or released from each other with equal ease.

Title: Method and apparatus for regenerating gas used in carbon dioxide laser generator
Inventor: TOSHIKUNI MASAMI
IPC: C01B32/50
Filed: 1992-03-11
Granted: 1999-05-04
Abstract: An improved method and apparatus for regeneration and reuse of He-N2-CO2 mixed gas for carbon dioxide gas laser generator.   The mixed gas after use is contacted with a precious metal catalyst (for example, Pt-Al2O3) at a temperature of 200 - 300 °C to react CO and O2 so as to form CO2.   Poisoning of the catalyst by NO x is suppressed at this relatively high temperature of reaction.          Deterioration of the catalyst can be prevented to some extent by pretreating the catalyst prior to use, and the activity of the catalyst, even if decreased, may be recovered by reactivation.
