Title: Improved adjuvants and vaccines
Inventor: HUNTER ROBERT L
IPC: A61K39/39
Filed: 1991-06-27
Granted: 1995-01-05
Abstract: The present invention comprises adjuvants which, when admixed with an antigen and administered into a human or animal, will induce a more intense immune response to the antigen than when the antigen is administered alone. In many cases, the adjuvant that is described as the present invention will increase overall titer of antibodies of a specific isotype which are specific for the antigen. For example, in mice, when the adjuvant of the present invention is admixed with a conventional antigen, the isotype that is induced in the mouse is changed from a predominantly IgG1 isotype to the more protective IgG2 isotype and, in some cases, IgG3 isotype. Thus, by practicing the present invention, one can improve the overall protective effect of conventional vaccines.

Title: Process and apparatus for preparing precipitated calcium carbonate
Inventor: VIRTANEN PENTTI
IPC: C01F11/18
Filed: 1998-09-08
Granted: 2002-04-18
Abstract: According to the process, limestone is burned at a high temperature to form calcium oxide and, thereafter, calcium carbonate is formed from calcium oxide in the presence of water and carbonate ions and the formed calcium carbonate is recovered. The formation of the carbonate may be performed by carbonating calcium oxide with carbon dioxide gas in the presence of water or water vapour, or by reacting calcium oxide with soda solution. According to the invention calcium oxide is converted to calcium carbonate without separate slaking and essentially without intermediate storage, in particular without intermediate storage between the burning of the starting material and the forming of calcium carbonate. With the aid of the invention a quite advantageous solution in view of heat economy is achieved.

Title: Antiidiotype vaccine against diseases caused by pathogenic responses of specific t-cell populations
Inventor: HOWELL MARK D
IPC: C07K16/42
Filed: 1993-04-26
Abstract: The invention relates to vaccines and means for vaccination of a host with the intention of preventing or controlling specific T-cell mediated pathologies. The vaccine is made of antiidiotype antibodies which are internal reflections of a segment of the T-cell receptor (TCR), found on the surface of the pathogenic T-cells. The vaccine is applied on the host in a manner which includes an immune reply, directed against the TCR of the pathogenic cells. This immune response regulates or eliminates the pathogenic T-cells, and in this way eliminates the pathogenesis. The invention relates to a mean for the determination of a suitable amino acid sequence of such a vaccine. 17 claims

Title: Hydraulic extension stop shock absorber mounting - uses volute spring as circlip holding seal and guide unit in place
IPC: F16F9/49
Filed: 1971-08-03
Abstract: The stop is particularly for use with single-tube shock-absorbers, where the combined guide and seal unit has the stop plate held clear of it by a volute spring. The volute spring also acts as the circlip holding the unit in place, and has two or more cranked sections in it. At one end it engages in a bush mounted centrally in the stop plate, and this bush is higher than the spring when compressed. The design combines simplicity of construction with a safe and fully protected mounting for the spring and constant limitation of axial movement of spring and plate.

Title: Telephone exchange switching and control matrix - has shift register connected as close ring to cross-points in matrix and clock pulse stepping
IPC: H04Q3/52
Filed: 1971-12-22
Abstract: The switching matrix has MOS transistor cross-points in which the gate capacitance of the MOS transistors is used a store for control information and in which each cross-point is connected to a stage in the controlling shift register. The shift register is connected as a closed ring with the cross-points in the matrix and is fed with a clock pulse, furthermore each stage of the shift register acts as controlling store and operate pulse for the cross-points whilst also incorporating OR-gate functions to test for free inlets and outlets along the two sides of the matrix. The design stores the switching instruction for the speech path in the matrix and uses the peripheral shift register circuitry for all marking, release and testing functions, giving the advantage of low power consumption and system flexibility.

Patent JP-3073246-B2 (JP)
IPC: B65D77/06
Filed: 1991-03-08
Granted: 2000-08-07
Abstract: This invention relates to a container for bulk goods, fluids and the like, comprising an outer envelope (131), which can be closed at both ends, and an inner member (132), which is connected to the outer envelope at at least four points spaced about the circumference of the outer envelope and has a length that is 30-100% of the height of the container to be formed. According to the invention, for obtaining a substantially block-shaped container with a bottom and cross-sections parallel thereto, substantially in the form of a rectangle deviating from a square, the starting-point is a rectangle with the desired outer dimensions and at least one inscribed circle which touches both long sides but not at least one short side of the rectangle. A first line extends parallel to the long side and through the centre of the inscribed circle and a second line extends parallel to a short side and through the centre of the inscribed circle. These lines divide the rectangle into subrectangles each having an angular point coinciding with one of the angular points of the rectangle. A bisector is drawn in the rectangle from each coinciding angular point. Located in each bisector is the centre of a further circle (135) which touches the long and the short side that meet at the angular point from which the corresponding bisector has been drawn. The intersections of said further circles and said inscribed circle define the points where the outer envelope is connected to the inner member. These intersections do not lie outside the subrectangle with the bisector in which lies the centre of the corresponding further circle. The length of the outer circumference of the outer envelope is defined by the sum of the four lengths of the arc of the four further circles between the points where the further circles intersect the inscribed circle and the sum of the lengths of such portions of the outer circumference of the inner member as are not covered by the further circles. <IMAGE>

Patent JP-S6412426-B2 (JP)
IPC: H04L29/06
Filed: 1981-06-19
Abstract: The present interface comprises means for exchanging information between a data terminal equipment (DTE) and data circuit terminating equipment (DCE) over a communications line. The specific information to be exchanged is the information indicating the delay period between a request-to-send received at the DCE and a clear-to-send condition occurring some time later in response to the request-to-send. The transmitter signal element timing or clock line (8) is used to convey the information from the DCE to the DTE. In response to receipt at the DCE of a request-to-send signal from the DTE, the DCE temporarily stops the transmission of clock pulses from clock (1), thus preventing the DTE from transmitting data. When the DCE modem has established carrier frequency and has completed its synchronization routine, the DCE re-enables the transmission of clock pulses from clock (1). The clock signals are transmitted at all times except during the request-to-send/clear-to-send delay period.
