Inventor: MURATA HIDEYUKI
IPC: H05B33/14
Filed: 1995-09-13
Abstract: According to the present invention, in a first aspect thereof, an organic electroluminescent device having an electroluminescent layer and/or a charge injecting/transporting layer formed out of a thin film of organic polymers of network structure which are excellent in heat resistance and durability, e.g., polyoxadiazoles is obtained by conducting a vapor deposition polymerization of a bifunctional monomer, a polyfunctional monomer of 3 or higher in functionality or a mixture of the polyfunctional monomer and bifunctional monomer and heating the resultant polymer in vacuum or an inert gas. In another aspect, an organic electroluminescent device having an electroluminescent layer and/or a charge injecting/transporting layer formed out of a thin film of polyoxadiazoles is produced without the formation of hydrogen halides (acids) as by-products by performing a vapor deposition polymerization of a monomer having two carboxylic acid halide groups and a monomer having two silylated carbohydrazide groups and heating the resultant polymer in vacuum or an inert gas.

Title: Guide blade for steam turbines
Inventor: ERNST PETER
IPC: F01D25/32
Filed: 1995-12-06
Abstract: The guide blade  (1)  has in the interior a hollow space (6) acted upon by vacuum and at least one opening,  provided  with  a  porous  cover (7)  having capillaries  (11),  for fluid suction in the region of the blade edge (4) situated downstream.

This is achieved when all capillaries of the porous cover (7) are filled with the fluid to be drawn off, and when a wall withstanding the application of vacuum  is  formed  by  the  porous  cover  (7)  and  the liquid-filled capillaries (11). This wall is permeable to the fluid only where it is wetted by the fluid.

Inventor: PRASAD RAVI
IPC: B01D71/02
Filed: 1996-03-21
Abstract: Oxygen is separated from a feed air stream to produce enriched oxygen permeate and oxygen depleted retentate gas.  At least first and second process stages, arranged in series, each include a solid electrolyte membrane separating gas chambers with a retentate side in the former and a permeate side in the latter, a cathode connected to the retentate side, and an anode connected to the permeate side.  Feed gas is introduced into a first gas chamber of the first process stage.  The cathode and anode of the first process stage are electrically energized to drive oxygen from the feed gas in the first gas chamber through the electrolyte membrane at a first flux into a second gas chamber.   Oxygen-depleted retentate gas from the first process stage is delivered to a third gas chamber of the second process stage.  Similarly, the cathode and anode of the second process stage are electrically energized by a current less than that of the first process stage and at a greater voltage. Oxygen-depleted retentate gas is withdrawn from the second process stage and permeated oxygen is withdrawn from the second gas chamber and a fourth gas chamber of the first and second process stages.

Title: Compositions and methods for eliciting ctl immunity
Inventor: VITIELLO MARIA A
IPC: A61K39/295
Filed: 1995-02-16
Abstract: Cytotoxic T lymphocyte responses are effectively induced to an antigen of interest, particularly viral, bacterial, parasitic and tumor antigens. Compositions, including pharmaceutical compositions, of CTL-inducing peptide and an adjuvant or a lipidated peptide which induces a helper T cell (HTL) response stimulate the antigen specific CTL response. Among the viral antigens to which the CTL responses are effectively induced in humans are those of hepatitis B. The CTL response may be optimized by a regimen of two or more booster administrations. Coktails of two or more CTL inducing peptides are employed to optimize epitope and/or MHC class 1 restricted coverage.

Title: Method and apparatus for diagnosis of skin lesions
Inventor: ECKHOUSE SHIMON
IPC: A61B5/103
Filed: 1997-01-16
Abstract: A method and apparatus for determining skin lesion parameters comprise directing light to the skin in which the lesion is located and monitoring the reflection of that light.  Then, the spatial and spectral distribution of the reflected light is analyzed.  The depth is determined by finding a location where the difference between a spectral intensity of reflected light and an average reflected intensity is greater than a maximal difference between the intensity of each point and an average intensity for normal skin.  The wavelength of the light reflected from the location is determined, and from the wavelength the penetration depth is determined.  The penetration depth is also the depth of the lesion below the skin surface.  The size is determined by determining a plurality of locations where the deviation between the spectral intensity and the average intensity is greater than the maximal deviation for normal skin.  Based on the spatial distribution of the locations the size of the lesion is determined.
Patent CA-2195296-A1 (CA)
Title: Trickle power supply
Inventor: LECH DAVID ALLEN
IPC: H02M5/257
Filed: 1997-01-16
Abstract: A trickle power supply for a light switch module according to the invention enables power to an electronic circuit to be taken directly off the hot line.  The power supply operates under what is referred to as the "switched leg theory".  All power is taken off the standard switched leg of the light circuit.  The power supply bleeds enough current to power its electronic circuitry without turning on the load device, i.e., the light.  At the same time, the maximum current to the load is limited to prevent shorting out of the power supply which would effectively disable the switch module.

Title: Power backup system for volatile memory
Inventor: HARPER JAMES DONALD JR
IPC: G06F1/28
Filed: 1995-09-15
Abstract: In a preservation system (170) for a volatile memory (171a-174a) associated with a nonvolatile memory (171b-174b), an energy storage portion accumulates energy while power is provided normally. When a power outage occurs, the stored energy is supplied to the volatile memory. Enough backup power is stored to accommodate the vast majority of unintentional interruption of power. Eventually, after removal of external power, when the backup power decreases to a predetermined amount, data in the volatile memory is transferred to the nonvolatile memory. The preferred use of the preservation system is an environment with vibration and/or power switching transients that affects the supply of power, such as an aircraft.

Abstract: On décrit une machine de conditionnement (20) à commande électronique qui comprend plusieurs postes de conditionnement (45, 50, et 55) à servomoteurs, qui sont entraîné par un ou plusieurs servomoteurs (170) pour remplir, et fermer un carton. Plusieurs amplificateurs de réglage (160) sont connectés aux servomoteurs pour en commander la rotation et donc le déplacement des différents éléments associés à chacun des postes de conditionnement. Cette machine de conditionnement comporte aussi au moins deux dispositifs programmables connectés de façon à pouvoir communiquer par un bus commun (270). Un gestionnaire d'axes programmable (90) permet de commander les amplificateurs de réglage (160) et donc les profils de déplacement des servomoteurs et des composants d'un poste de traitement donné. Un circuit de commande à logique programmable (80) reçoit et émet des signaux d'entrée/sortie relatifs aux divers postes de conditionnement. Le gestionnaire d'axes programmable et le circuit de commande à logique programmable échangent des valeurs variables de données par le bus commun en utilisant des empreintes prédéterminées affectées à chaque valeur variable. L'utilisation d'un protocole empreintes/valeurs variables permet des communications à grande vitesse entre ce gestionnaire d'axes programmables et ce circuit de commande à logique programmable, on peut donc considérer qu'ils forment un unique module de commande.
