Patent EP-0095458-A4 (EP)
Title: Continuous-line operations for desulfurizing coal.
Inventor: GROVE F ALLEN
IPC: C10L9/10
Filed: 1981-11-30
Abstract: Continuous-line operations for desulfurizing coal utilizing fluid treatments including gaseous reactant treatment of raw coal. Raw coal is pulverized at (20) to a selected particle size classification. Moisture level is controlled to provide desired work product characteristics enabling impingement with a reactant gas while avoiding dispersion of the work product and maintaining desired properties for mechanical control of movement through reaction zones. Reactant contact control includes control of rate of movement of the work product, control of reactant injection, and control of reaction time while maintaining continuous-line movement of the work product. Provision is made for ease of separation of extracted sulfur as useful by-product and passivation treatment is applied to the desulfurized coal.

Title: Internally ventilated noise suppressor with large plug nozzle.
Inventor: KLEES GARRY WILLIAM
IPC: F02K1/62
Filed: 1982-03-17
Abstract: A jet engine noise suppressor particularly adapted for supersonic aircraft. The nozzle (10) has an internal wall surface (70) around a generally centrally positioned body (50) and an annular area (62) extending between the wall and the body. In this area there are separate gas and air flow ducts (64, 66) having entrance ends (82, 80) and exit ends (76, 78), the entrance ends of the gas ducts extending annularly around the body (50) to receive gas exhaust from the engine and the air ducts have entrance ends annularly outwardly of the gas ducts along the wall (70). There are openings (26) in a wall (14) upstream of the ducts to supply ambient air to the entrance ends (80) of the air ducts. There are doors (20) and actuators (24) operable to open and close the openings (26). The ducts are arranged to direct the flow patterns at the exit ends (76, 78) in a relationship inverted from that existing at the entrance ends (80, 82) so that the gas ducts (64) discharge annularly outwardly along shroud (100) and the air ducts (66) discharge annuarly inwardly along the body (50). There is an annulus downstream of the ducts extending between the shroud (100) and the body (50) in which there are longitudinally directed flaps extending annularly around the body and within the shroud. The flaps (126) vary the flow path sizes of the gaz exhaust and air ejected outwardly of the ducts according to various flight mode requirements of the engine. There is also thrust reverser (102) in the shroud which is translatable from an inner position to an outer position, the flaps directing the gas flow through the thrust reverser for stopping the airplane on landing.

Title: Ear pathology diagnosis apparatus and method.
Inventor: TEELE JOHN H
IPC: A61B5/12
Filed: 1983-03-16
Abstract: A method and apparatus for diagnosing pathologies of the ear, particularly pathologies such as otitis media, directs into the ear canal (290) a sequence of acoustic waves covering a range of frequencies from a few hundred Hz. to several kHz. and determines the presence or absence of resonance when the incident and reflected waves are combined. The measurements are made without pressurizing the ear canal (290) and it is not required that the contact between the instrument and the ear be air-tight. Accordingly, essentially no discomfiture of the patient results from use of the instrument. The requisite measurements are made quickly (of the order of tens of milliseconds) and thus the distorting effects of patient movement are effectively eliminated. An improved version of the instrument is completely self-contained and hand-held and has the form of a "tee" in which the resonant frequency and amplitude are visually indicated by means of horizontally and vertically disposed arrays of light-emitting diodes (414 and 416).

Filed: 1984-12-11
Abstract: A deoxygenation process includes the steps of adding hydrazine to a liquid containing dissolved oxygen, passing the liquid through a bed of activated carbon to catalyze a reaction between the dissolved oxygen and hydrazine whereby carbon contaminants are added to the liquid, and removing the contaminants. In another embodiment, unreacted hydrazine that remains in the liquid following the catalysis is removed by passing the liquid through an ion exchange resin. In still another embodiment, an activated carbon-catalyzed deoxygenation process employing hydrazine is practiced on a mobile platform and the process further includes the steps of transporting the apparatus to a regenerating station for regeneration. The invention also includes apparatus for carrying out the process.

Title: Modified insulin precursors products and processes.
Inventor: SCHENDEL PAUL
IPC: C07K14/62
Filed: 1985-08-30
Abstract: Products and processes for the generation in polypeptides of protease cleavage sites, thereby making said cleavage sites accessible for in vitro cleavage by highly specific proteases. More particularly, this concept has been employed in the production from a modified proinsulin of an insulin containing a B-chain having the proper carboxyl-terminus. A modified proinsulin with several amino acids deleted from its C-chain was cleaved at Thr30-Asp31 and at a site equivalent to the Arg65-Gly66 of the natural proinsulin C-chain (this site having been modified to a Met-Gly sequence) to yield active human insulin in vitro.
Patent EP-0359819-A4 (EP)
IPC: G05B19/416
Filed: 1988-04-27
Abstract: Un régulateur de vitesse sert à réguler la vitesse d'une main de robot ou d'une partie en mouvement d'une machine-outil à command e numérique. Ce régulateur possède un moyen d'intervention sur la vitesse permettant de modifier selon une cadence prédéterminée la vitesse d'instruction de la partie en mouvement, et des moyens d'accélération/décélération (2X, 2Y) présentant une constante de temps inversement proportionnelle à la vitesse établie par le moyen d'intervention. Lorsque la valeur d'intervention sur la vitesse est modifiée, la constante de temps du moyen d'accélération/décélération (2X, 2Y) est modifiée en fonction de la vitesse d'instruction, de sorte qu'une valeur de regroupement dans la valeur impulsionnelle d'instruction devient constante pendant l'accélération ou la décélération. Ainsi, la régulation de la partie en mouvement lui permet de se mouvoir à une vitesse prédéterminée sans modification du lieu géométrique au niveau des points d'attaque.
Patent EP-0432180-A4 (EP)
Title: Timing apparatus
IPC: G01V15/00
Filed: 1989-08-08
Abstract: An electronic timing apparatus for determining precisely when vehicles pass over a particular line on a road, particularly a race track (20), has a series of separate loop antennas (26), arranged in closely adjacent relationship one to another across the width of the track. Each vehicle (81, 82) is fitted with a transmitter (28) for transmitting a unique identifying signal which is received by a loop antenna as the vehicle passes over the line. The width (x) of the antenna loops relative to the width of the vehicles is such that only one transmitter (28) can pass over a particular loop at the one time whereby when two or more vehicles cross the line simultaneously, signals from the respective transmitters are received in different antennas. A respective receiver module (27) is connected to each antenna loop and processes the identifying signal which is then fed to a micro-controlled (43) which calculates the time at which the particular vehicle crossed the line. A supervisory computer (24) collates and provides a database of timing information.

Title: Libraries of modified peptides with protease resistance
Inventor: BARTLETT PAUL A
IPC: A61K47/48
Filed: 1991-06-14
Abstract: Peptoids are provided which are polymers comprised of monomer units wherein the monomer units include at least some substitute amino acids and may include conventional amino acids. The peptoids can be synthesized in large numbers so as to provide libraries of peptoids which can be screened in order to isolate peptoids of desired biological activity. Certain peptoids are designed to mimic as closely as possible the activity of known proteins. Other peptoids are designed so as to have greater or lesser activity than known proteins and may be designed so as to block known receptor sites and/or elicit a desired immunogenic response and thereby act as vaccines. A range of different amino acid substitutes are disclosed, as are their methods of synthesis and methods of using such amino acid substitutes in the synthesis of peptoids and peptoid libraries. Methods of screening the libraries in order to obtain desired peptoids of a particular biological activity are also disclosed. The peptoids are preferably linked to a pharmaceutically active drug forming a conjugate with increased binding affinity to a particular biological receptor site.
