Title: Ultrasonic scanning of the eye using a stationary transducer
Inventor: COLEMAN DONALD J
IPC: A61B8/10
Filed: 1998-05-26
Abstract: An apparatus is provided for high frequency ultrasound examination of the anterior segment of a patient's eyes (10, 12), the patient being in generally supine position. A liquid bath (14) is established about a first eye (10) of the patient to be examined. A fixed ultrasound transducer (20) is placed in contact with the liquid bath (14), directs the beam of ultrasound energy to the first eye (10), and receives echoes of the ultrasound energy. A fixation source (30) is juxtaposed to the second eye (12) of the patient, and displays a fixation target. A controller (40) operates the fixation source (30) to move the fixation target relative to the second eye (12), while the patient moves the second eye (12) so as to remain focused on the fixation target. The movement of the second eye (12) causes the first eye (10) to move concurrently, enabling relative movement between the beam of ultrasound energy, and the anterior segments of the first eye (10) while maintaining near orthogonal between the ultrasound beam, and the surface of the eye. By tracking the position of the second eye (12) the position of the first eye (10), and hence of each pulse/echo sequence is ascertained enabling image construction, and bio-metric determinations of the anterior segment anatomy to be performed.

Abstract: The present staircase includes a permanent framing made of metallic stringers, one of which being typically secured to a half-timbering.      Vertically extending step supports are secured along the stringers and each include upper and front flanges adapted to be secured respectively to a tread and to a riser of each step of the staircase. A temporary staircase may be easily obtained with the present kit for use during construction, wherein a number of L-shaped steel step units are laid onto the step supports to form a successive series of alternating risers and treads. Then, these L-shaped steel units can be removed and replaced by finished steps of various configurations. If the staircase has an exposed side, a finishing stringer is provided thereat to conceal the structural metallic stringer.      Various support systems, including corner posts and brackets, are provided for supporting various horizontal and vertical structural components of the framework of the staircase, including when the staircase is L-shaped or U-shaped thereby including a turn in the staircase with flaring steps, and also possibly a landing. Various finished wooden components are provided to completely cover the metallic framework, including treads, risers, false or decorative stringers, moldings, etc. On the outside, or large, ends of corner steps, metallic L-shaped stringers may be mounted to the dwelling's framework and used to support the steps instead of the aforementioned step supports.

Title: An aqueous amine fluoride neutralizing composition for metal pretreatments containing organic resin and method for metal pretreatment
Inventor: PAWLIK MICHAEL J
IPC: C23C22/34
Filed: 1998-10-26
Abstract: An amine fluoride neutralizing composition comprised of (a) about 1 to about 50 weight percent hydrofluoric acid, (b) optionally up to about 18 weight percent of a complex fluoride containing compound, and (c) about 45 to about 99 weight percent of an amine. The weight percentages are based on the total solids of the amine fluoride neutralizing composition. Also provided is a method of using the amine fluoride to produce a non-chrome pretreatment composition comprised of mixing from about 20 to about 30 weight percent of the amine fluoride neutralizing composition with about 70 to about 80 weight percent of at least one organic resinous material having an organic resinous material that is amine neutralizable; and adding water so as to achieve a total solids content of the non-chrome pretreatment composition of about 20 to about 60 weight percent. The pretreatment composition may be further diluted with water to form a non-chrome pretreatment bath having a total solids content of about 0.1 to about 10 weight percent, preferably from about 1 to about 5 weight percent. The amine fluoride neutralizing composition allows for a simplified manufacturing process of non-chrome pretreatment compositions by allowing the use of one, less corrosive, easy to handle compound rather than three separate materials which may be hazardous to handle, and it allows for the insertion of fluoride into a pretreatment composition without the introduction of extraneous cations which can destabilize or diminish the effectiveness of the pretreatment concentrate or bath.

Abstract: The invention relates to a method for determining the volumetric proportion of liquid water and the density of snow, and to a device for carrying out said method. The inventive method is designed in such a way that interference can be excluded by the measuring system itself. A probe consisting of at least three electric conductors (1, 2) which are arranged parallel to and at different distances from each other is positioned before snowfall or placed in snow which has already fallen (3). Two of the conductors are subjected to the action of an electromagnetic signal with a frequency for which the dielectricity coefficients of water and ice are known and the dielectricity coefficient of the snow is then determined with an inevitable air gap around the probe, based on the transmission behaviour of the electromagnetic signal.

Title: Procedes et systemes pour la production en serie de materiaux radioactifs
Inventor: WEEKS KENNETH J
IPC: A61F2/82
Filed: 1999-04-08
Abstract: Cette invention se rapporte à des systèmes et à des procédés permettant de produire en série des matériaux radioactifs et des structures, tels que des extenseurs médicaux. A cet effet, un réseau tridimensionnel de cibles est placé dans la trajectoire d'un faisceau d'électrons émis par une source (par exemple un accélérateur linéaire). Un convertisseur de Bremsstrahlung est placé entre le réseau de cibles et la source du faisceau d'électrons, afin de convertir ce dernier en un faisceau irradiant qui contient à la fois des électrons et des photons. Les électrons du faisceau irradiant peuvent être amenés à s'éloigner par divergence de la trajectoire du faisceau (par exemple par des moyens de balayage magnétique) et à suivre une trajectoire divergente, pour que les cibles soient irradiées essentiellement par des photons. Le faisceau d'électrons peut en outre être conditionné (focalisé), à l'aide de bobines d'agitation magnétique placées en amont du convertisseur. Le convertisseur de Bremsstrahlung est de préférence formé par plusieurs convertisseurs individuels différents les uns des autres en terme d'épaisseur et en terme de haute teneur en matériau Z. Un ou plusieurs de ces convertisseurs individuels peuvent ainsi être placés dans la trajectoire du faisceau, selon les besoins en fonction des cibles à irradier.

Title: Focus control for search lights
Inventor: MENDEZ DAVID
IPC: F21Y101/00
Filed: 2000-12-29
Abstract: The focus angle .theta. of a search light (12) mounted on a helicopter (10) or other platform (10) is narrowed or widened by rotating a bidirectional focus control cam (42) in a clockwise or counterclockwise direction as selected by a manually operated three-position control switch (SW1) which determines the rotational direction of a DC motor (28) driving the bidirectional focus control cam (42). The DC motor (28) has first and second terminals (92, 93) which are selectively connected to either a DC power source (72) or ground (73) by a double-pole, single throw dual relay (60) which reverses the polarity and thus the direction of rotation of the DC motor (28). The dual relay (60) is connected by the same single wire interface (32) to the manually operated control switch (SW1), which manually operated control switch (SW1) is within a control box (62) located in the helicopter (10). By operating the manually operated control switch (SW1) to connect coils (76,78) in the dual relay (60) to either a power source (72) or to ground (73), the coils (76,78) are selectively energized or deenergized causing the dual relay (60) to operate switches (SWR, SW3) that reverse polarity of current flowing through the DC motor (28). This selectively changes the direction of rotation of the bidirectional cam (42) which advances and retracts a focusing reflector (47) within the search light (12) to widen and narrow its focus angle .theta., thereby widening and narrowing the area (16) illuminated by the search light beam (14).
