Patent EP-0816933-A1 (EP)
Inventor: SNELLING CHRISTOPHER
IPC: G03G15/05
Filed: 1997-06-24
Abstract: Pyroelectric materials are used to create net charge/surface potentials for use in
xerographic charge and transfer steps. Heating and cooling a pyroelectric film (61), such as,
polyvinylidene fluoride, on a conductive roll (62) induces thermal expansion or contraction which
create surface charge density changes that can be used to charge a photoconductive surface (90,
95, 97) and/or transfer an image from a photoconductive surface (90, 95, 97) to a copy sheet.

Abstract: L'invention a trait à un raccord de tiges utilisable pour raccorder des segments de colonnes de tubes pour forages. Ce raccord est constitué d'une connexion d'une tige (10) et d'un boîtier (12) du type employé dans le tubage, le cuvelage de puits de pétrole et analogue. Ce raccord, susceptible d'être enfoncé, est pourvu de deux épaulements de couplage (19, 21) et de faces en avancée (18, 20) sur la tige et le boîtier (10, 11). La connexion est conçue de telle sorte que les charges de compression exercées sur la tige et le boîtier (10, 11) sont transférées, dans une large mesure, par la tige et les épaulements de boîtier (19, 21) plutôt que par la partie filetée (16, 17). Ces deux épaulement de couplage (19, 21) permettent d'améliorer sensiblement la capacité du raccord à résister à la forte compression axiale survenant lors de l'enfoncement du tube dans le sol.

Abstract: The present invention proposes a process and a device which permit to improve the efficiency of energetic gas turbines operating in user regions with outside temperatures from -5° C. to +5° C. Unlike in the state of the art, no heat is withdrawn in this connection from the gas compressor (3) when the heat requirement rises in the overall intake system, but successively by using first the off-air heated by the generator (2) for heating the intake air in the intake duct (12, 12') and subsequently withdrawing additional heat in the form of the heat of an off-heat system (8) generated at the end of the heat circulation. When additional heat is required, heat can be withdrawn from the compressor (3) via a bypass conduit (20).

IPC: C12Q1/6851
Filed: 1997-05-02
Abstract: A method for the quantitative monitoring of gene expression without either co-amplification of an added template or use of an endogenous constitutive transcript is provided. The process involves a duplex amplification reaction in which a single set of primers is used to amplify both genomic DNA and expressed mRNA from the same gene sequence. These primers are targeted for sequences flanking the splice junction/intron sequences for the mRNA/DNA respectively. By their use, any suitable nucleic acid amplification technology yields mRNA and DNA amplimers which are distinguishable by length and sequence heterogeneity. These amplimers are present in the final amplification reaction in ratios which are dependent upon the ratios of the expressed mRNA to the DNA in the sample, allowing the quantitation of mRNA in a sample which is normalized to the number of copies of genomic DNA since the genomic DNA acts as the internal quantitation standard, and in effect yields the amount of mRNA per cell. Any detection methodology which can detect amplimers of different lengths or sequences can be used for post amplification quantitation. This strategy may be employed for any gene system in which the mRNA sequence differs from the original genomic DNA sequence. The invention may be used, for example, in the determination of gene expression in both research and commercial applications.

Abstract: The invention is in the field of vaccines and immunogenic preparations. Normally in these preparations antigens and carrier compounds are irreversibly coupled in a stable bond. The invention, to the contrary, provides vaccines and immunogenic preparations in which the antigen (be it protein or peptide or carbohydrate or any other molecule to be used as an antigen for immunization/vaccination procedures) and the carrier compound are coupled in a reversible and labile way, with a so-called labile link. In this way, as is demonstrated in the experimental part of this application, surprisingly a better immune response can be elicited by an in itself poorly immunogenic antigen than by methods that provide a stable link between the antigen and carrier compound.

Abstract: An object of the invention is to provide a catalyst for purifying sufficiently both
NOx at high exhaust gas temperature and HC and CO at low exhaust gas
temperature in using engines normally operated with excess air such as diesel or
lean-burn engine. 
The catalyst comprises the following two types of catalysts in the form of mixture or
double layers supported on a honeycomb substrate; (a) a first type zeolite catalyst
in which the active metal becomes supported on the zeolite by ion-exchange
process and (b) a second type zeolite catalyst in which the active metal becomes
supported on the zeolite by other process than ion-exchange. At high exhaust gas
temperature, the first type zeolite catalyst converts paraffin type HC and/or olefin
type HC into aromatic HC. The second type zeolite catalyst can reduce NOx into N 2 
by making use of the aromatic HC as a reductant remaining in the gas even at high
temperature. 
At low exhaust gas temperature, the first type zeolite catalyst converts a medium
size (medium carbon number ) aromatic HC into a small size olefin type HC
(cracking ) and the second type zeolite catalyst can rapidly oxidize the small size
olefin type HC to form H 2 O and CO 2 . As a whole the catalyst gains a performance
improvement in both purification of NOx at high temperature and its activity at low
temperature.

Abstract: Methods and apparatus are described for facilitating
multiple data communications with a first platform (100, 102,
and 104) using a single communication conduit (108) having
first and second channels. First data are transmitted between
the first platform and a second platform (114) via the first
and second channels (202). It is determined whether an
incoming call comprises second data of a particular type
(206). Where the incoming call comprises the second data of
the particular type (208), transmission of the first data via
the second channel is inhibited (226) thereby enabling
reception of the second data by the first platform via the
second channel while the first data continue to be transmitted
via the first channel. The second data are then received at
the first platform via the first channel (230). Transmission
of the first data via the first and second channels is resumed
in response to termination of transmission of the second data
(266).
