Patent EP-0416037-A4 (EP)
Title: Superoxide dismutase analogs having novel binding properties
IPC: A61K38/44
Filed: 1989-06-06
Abstract: Superoxide dismutase (SOD) analogs whose amino acid sequence includes a heterologous peptide domain such as the RGDX tetrapeptide found in fibronectin or the LGGAKQAGDV decapeptide found in fibrinogen that enables the analog to bind to a moiety that is normally present at sites of desired SOD therapy. The domain is incorporated into the SOD sequence in a manner in which it is available to interact with such moieties but does not destroy the enzymatic activity of the molecule. The inclusion of the domain enables the analog to more readily access the target tissue upon which it is to act and/or increase the corporeal half-life of the molecule.

Patent EP-0478635-A4 (EP)
Title: Cardiac assist pump
IPC: A61M60/871
Filed: 1990-06-18
Abstract: A centrifugal pump for left ventricle assist includes a pump housing forming an impeller chamber with inlet and outlet passages and enclosing an impeller rotatable to move blood through the impeller chamber, and a rotor chamber enclosing a rotor integral with the impeller and rotatable to drive the impeller. An elastically deformable seal member separates the rotor and impeller chambers, and includes an annular lip seal surrounding a shaft which joins the impeller and rotor. A saline solution is supplied at a constant fluid flow rate to the rotor chamber through an inlet passage, and leaves the rotor chamber by perfusing into the impeller chamber along the interface between the shaft and lip seal. The saline solution thus provides hydrodynamic bearings between the rotating shaft and rotor, and the fixed pump housing and lip seal, and further prevents blood in the impeller chamber from entering the rotor chamber. The lip seal is configured to encourage flow of saline solution along the lip seal/impeller shaft interface, while resisting the flow of blood along the interface.

Title: Electrostatic vapor-aerosol generator.
Inventor: PELTIER MARK E
IPC: A61L9/12
Filed: 1992-03-03
Abstract: The controlled generation of vapors and/or aerosols from liquids is accomplished by applying a regulated, DC voltage to a wicklike, porous emitter or generator assembly which is supplied with the desired liquid to be vaporized. An electrostatic charge is applied to the liquid by means of an electrode positioned in contact with the wick assembly and connected to the DC power supply. The wick assembly includes a porous, capillary material, such as braided fibers, through which the liquid passes to exposed, vapor-emitting fiber tips. The environment in a room, enclosed spaced of any kind, or a building may be aromatically conditioned and/or have its quality modified and enhanced by using a selected liquid conditioning substance such as an aromatic oil, deodorant, disinfectant, fumigant, fungicide, insecticide, or bactericide. Charged, conditioning vapors may be discharged into the circulating air of a building air conditioning system by mounting an emitter assembly within an air handling duct, directly in the moving air stream.

IPC: G11B7/128
Filed: 1993-12-23
Abstract: Method and apparatus for improving the characteristics of the surface effects recorded on an optical disc, for use with an optical recording apparatus which includes a writing light beam source and an optical modulator for modulating the intensity of the writing beam of light above and below a threshold level of a moving recording medium in response to a modulator drive signal for recording information on the medium, the light beam being capable of forming a track of surface effects or indicia in the moving recording medium when the writing beam is above threshold and incapable of forming surface effects in the moving recording medium when the writing beam is below threshold. The method includes receiving a substantially rectangular waveform having leading and trailing edges, provided as a modulator drive signal to modulate the writing beam to a peak power above threshold and to a minimum power level below thresholds, respectively, and producing a shaped modulator drive signal by increasing the peak power of the writing beam responsive to the occurrence of the leading edges, by decreasing the time the shaped modulator drive signal is above threshold in order to maintain a prescribed duty cycle in the track of surface effects in the moving recording medium, and by producing symmetrical leading and trailing edges of the surface effects.

Inventor: MANTEL G DAVID
IPC: H03M13/27
Filed: 1995-12-12
Abstract: Un système de transmission (100) code et décode des informations à l'aide d'au moins quatre niveaux de modulation servant à transmettre les informations sous forme de symboles représentant des bits de symboles dans des positions de bits de symboles. Au moins une des positions de bits de symboles présente un taux d'erreur supérieur à celui d'une autre des positions. Un processeur (204) code (702) les informations en un nombre pair de mots de code et transmet lesdits mots de code sous forme de flux de données entrelacées. Le processeur (204) réorganise (706, 708) l'ordre de transmission des bits de mot de code de façon prédéterminée pour produire un ordre de transmission modifié, de sorte que les mots de code sont transmis (710) avec des taux d'erreur sensiblement égaux. Un récepteur (110) reçoit et démodule (712) le flux de données entrelacées pour extraire les bits de mot de code, avant de les réordonner (714, 716) pour annuler les modifications de bits résultant de la modification de l'ordre de transmission, ce qui rétablit les mots de code. Le récepteur décode alors les mots de code pour récupérer les informations.

Title: Head rail-mounted actuator for window coverings
Inventor: DOMEL DOUGLAS R
IPC: E06B9/68
Filed: 1996-11-08
Abstract: A mini-blind actuator has a motor and a housing that holds the motor and a dc battery. The rotor of the motor is coupled to the baton of the mini-blind for rotating the baton and thereby opening or closing the slats of the mini-blind. Alternatively, the rotor is coupled to the tilt rod of the blind to rotate the tilt rod and thereby open or close the slats of the mini-blind. A control signal generator generates a control signal for completing the electrical circuit between the battery and the motor in which reference to an element in the singular is not intended to mean "one and only one" unless explicitly so stated in the claim, but rather "one or more". The control signal can be generated in response to a predetermined amount of daylight or in response to a user-generated remote command signal. The actuator can be used to rotate the slats of horizontal or vertical blinds, or the sections of a pleated shade. Or, the actuator can be used to rotate the hollow rotatable tube of a roll-up shade.
