Title: Compounds named the adenophostins, their preparation and their therapeutic use
Inventor: TAKAHASHI SHUJI
IPC: C12N1/20
Filed: 1992-08-13
Granted: 2002-08-06
Abstract: Compounds of formula (I):      (wherein R represents a hydrogen atom or an acetyl group); which eve have named "the adenophostins", and salts and esters thereof, have the ability to increase intracellular calcium ion concentrations by acting on the inositol 1,4,5-trisphosphate (InsP3) receptors which exist in the endoplasmic reticulum, and can therefore be used fox the treatment or prophylaxis of cerebral disorders. They can be prepared by cultivation of a microorganism of the genus Penicillium, e.g.      Penicillium brevicompactum SANK 11991 (FERM BP-3499) or Penicillium brevicompactum SANK 12177 (FERM BP-3500).

Title: Automatic flowgraph generation for program analysis and translation
Inventor: SITES RICHARD L
IPC: G06F9/45
Filed: 1992-03-05
Granted: 1998-05-19
Abstract: A program is translated by automatically generating a flowgraph, using the flowgraph to analyze the program to provide information about blocks of instructions in the flowgraph, and then using the flowgraph and the information about the blocks of instructions to generate translated instructions. The flowgraph is used during analysis of the program to control gathering and storage of information about the blocks of instructions and checking for consistency of the information over paths in the flowgraph. The information for each block includes, for example, register usage, stack usage, condition code usage, return mask usage, and any occurrence of non-standard returns. This information is used to detect possible errors and translation difficulties such as stack depths that do not match on all incoming paths, return masks that do not match over all incoming paths to a block, use of uninitialized registers or condition codes, failure to align the stack on longword boundaries, and nonstandard returns such as callbacks to procedure parameters. An error discovered during analysis is reported, for example, by generating an error-specific flowgraph in which the paths and blocks of instructions relevant to the error are indicated.

Title: Semiconductive copolymers for use in luminescent devices
Inventor: HOLMES ANDREW
IPC: H01L33/08
Filed: 1991-08-22
Granted: 2005-05-10
Abstract: A semiconductive conjugated copolymer comprises at least two chemically different monomer units which, when existing in their individual homopolymer forms, have different semiconductor bandgaps. The proportion of said at least two chemically different monomer units in the copolymer is selected to control the semiconductor bandgap of the copolymer so as to control the optical properties of the copolymer. The copolymer is formed in a manner enabling it to be laid down as a film without substantially affecting the luminescent characteristics of the copolymer and is stable at operational temperature. The semiconductor bandgap may be spatially modulated so as to increase the quantum efficiency of the copolymer when excited to luminescence, to select the wavelength of radiation emitted during luminescence or to select the refractive index of the copolymer.

Abstract: Nouveau procédé de moulage de structure composite dans lequel la partie finie présente une géométrie de forme nette ne requérant qu'un réusinage minimum et présentant des caractéristiques de consolidation et de surface améliorées. Une préforme composite présentant une partie d'âme creuse contenant un insert en polymère est introduite dans une cavité de moule. Une extrémité de l'âme de la préforme est obturée et la préforme ainsi que l'insert en polymère sont chauffés afin de fusionner la matrice composite et le polymère de l'âme. On applique une pression à l'âme au niveau de l'autre extrémité de la pièce, provoquant une dilatation radiale de cette dernière contre la cavité moulée ainsi qu'une consolidation du composite dans une pièce finie. L'invention concerne également une pièce finie utilisée comme constituant d'un implant orthopédique.

Abstract: A water treatment system including a tank for containing a solid treatment product such as a solid halogen. The water treatment system is adapted to be used in combination with a cooling system wherein treated water is fed to the cooling system through an outlet conduit leading from the tank. Drainage of water from the tank is facilitated by use of an eductor connected to an inlet conduit for the tank whereby water is drained from the tank to the inlet conduit and back to the outlet conduit, and is thereafter conveyed back to the cooling system. Thus, a closed system is formed by the treatment system in combination with an associated cooling system wherein the closed system is substantially environmentally safe in that drainage of the tank outside of the closed system is avoided.

Abstract: Soil/metal supporting structures commonly include panel sections having a short radius of curvature in the range of 750 mm to 2,500 mm. In such soil metal supporting structures the panels are of heavy gauge in the range of 2 mm to 10 mm thickness.  Usually, expensive tooling and forming techniques are required to cold form the heavy gauge material into a curved shaped having such short radius. Such expensive techniques have been eliminated by this invention by virtue of the improvements comprising:      a) the panels have a high degree of ductility before being cold formed, such high degree of ductility being determined by a ratio of specified minimum yield strength to specified minimum tensile strength equal to or less than 0.8; b) the panels are cold formed with cross-corrugations in each of the inside ridges of the longitudinally formed corrugations of the panel, the cross-corrugations are sinusoidal and cross section and allow the cold forming of a short radius panel on a consistent basis without dislodging panel shape to facilitate thereby interconnection of the panels for the structure; c) the cross-corrugations have a depth in the range of 4 mm to 12 mm and a pitch of 40 mm to 70 mm; and d) the cold formed panels of short radius by virtue of the sinusoidal shaped cross-corrugations provide a finished panel with marginal increase in ductility, thereby allowing for either plastic or elastic analysis in providing the soil/metal supporting structure.

Title: Process for reducing data in the transmission and/or storage of digital signals from several interdependent channels
Inventor: HERRE JURGEN
IPC: H04L27/12
Filed: 1993-05-18
Granted: 2007-01-16
Abstract: A process for reducing data in the transmission and/or storage of digital signals of several interdependent channels is described.      As the signals from the channels are not independent of one another, an additional data quantity reduction is possible during transmission.      In known processes for the coding of signals from two stereo channels, in the case of an unfavourable signal composition interference can be caused by the coding process and cannot be concealed by the signal actually present in the channel and consequently reduce listening enjoyment.      In the process according to the invention and with the aid of the spectral values of corresponding blocks of several channels, there is a balancing of the necessary data rate for a separate coding of the two channels and for a joint coding. There is a joint coding of the channels for as long as the data rate for the joint coding does not exceed by a predeterminable value the data rate for the separate coding of the particular channel.      In this case the spectral values of the corresponding blocks are similar, so that a joint coding is preferred.      In the case of highly dissimilar signals the balancing leads to a separate transmission of the signals. In order to ensure that there is no interference, temporarily no use is made of the joint coding of several channels.
