Abstract: A headlight for a motor vehicle is provided for generating a light beam, and particularly a dipped beam, of a given configuration. The headlight has a light source, a reflector of the elliptical type having a first focus in the vicinity of which the light source is situated, and a lens placed in front of the reflector. The reflector has at least two zones which are situated side by side and which are adapted to form, in a focal region of the lens, patches of light which are preformed in width, and overlap each other in a horizontal direction.

Abstract: A vibrator module adapted for use in a taper apparatus for advancing carrier tape having a plurality of compartments and for placing parts in the compartments. The vibrator module includes a motor that includes an output shaft that rotates in response to operation of the motor. The vibrator module also includes an eccentric weight mounted to and rotatable with the output shaft. The eccentric weight causes the motor to vibrate in response to rotation of the output shaft and eccentric weight. The vibrator module further includes a vibration transferring member interconnected with the motor and operable to transfer vibrations from the motor to the carrier tape to cause the parts to settle into the bottoms of the compartments.

Abstract: An imager for illuminating and imaging encoded symbology to facilitate decoding of the symbology and which provides both “bright field” and “dark field” illumination patterns is provided with an illumination directing device to direct the “bright field” illumination pattern into an alternative “dark field” illumination pattern. In one embodiment the illumination directing device takes the configuration of a disc that is selectively positionable in front of the imager and removable therefrom depending upon whether or not the illumination pattern is to be changed. The disc snap fits into a position at the front of the imager housing and includes a fresnel configured outer ring, a light blocking inner ring, and a light transmissive center. The fresnel configuration receives light and redirects the light forward of the imager and towards a center line passing through the device to provide the alternative illumination pattern.

Abstract: A closed-loop control system for the superficial photoablation of stromal tissue from an exposed surface includes an active mirror for directing a diagnostic laser beam through the exposed surface to a focal point on the retina of an eye. The reflected beam is analyzed by a detector to identify a distorted wavefront that is indicative of required corrections, and an induced wavefront that is indicative of optical aberrations that have been mechanically introduced when the stromal tissue was exposed. A compensator alters a desired wavefront with the induced wavefront to create a rectified wavefront. A comparator then compares the rectified wavefront with the distorted wavefront to create an error signal. In the operation of the closed-loop control system, the error signal is used to maintain a focal point on the retina for the diagnostic laser beam. Also, at a null, the error signal indicates when the required amount of stromal tissue has been photoablated.

Abstract: The invention pertains to dielectric films for the production of microelectronic devices. A spin-on glass film is produced by depositing a silazane polymer containing composition film onto a substrate and then exposing the film to electron beam radiation. The electron beam exposing step is conducted by overall exposing the dielectric layer with a wide, large beam of electron beam radiation from a large-area electron beam source.

Abstract: A puncturing device that can be observed by means of tomography, such as MRI, which can be operated simply, safely and reliably. One embodiment of the invention includes a cuboid body containing a needle guide, which extends to a base area of the cuboid body. The base area is configured for placement on the skin of a patient. Marker bores disposed in the cuboid body and containing a contrast medium make it possible to precisely align the needle guide with a tomography picture plane in that the images of the bores have to assume a particular mutual configuration on a monitor. This allows a puncture needle used with the needle guide to be observed along its entire path on tomograms.

Abstract: A fiber optic light source having an improved cooling scheme for preventing heat damage to the fiber optic cable input ends. The housing for the light source is divided into two sections, with a separate cooling air supply for each section. The first section is provided with a high volume cooling air flow for general area cooling of the lamp assembly, power supply and other exothermic components. The second section is provided with a high velocity cooling air flow directed at the fiber ends. The second cooling air flow is isolated from the heat generated by the lamp assembly and is provided to the fiber ends at essentially ambient temperature.

Abstract: The present invention provides drilling systems for drilling subsea wellbores. The drilling system includes a tubing that passes through a sea bottom wellhead and carries a drill bit. A drilling fluid system continuously supplies drilling fluid into the tubing, which discharges at the drill bit bottom and returns to the wellhead through an annulus between the tubing and the wellbore carrying the drill cuttings. A fluid return line extending from the wellhead equipment to the drilling vessel transports the returning fluid to the surface. In a riserless arrangement, the return fluid line is separate and spaced apart from the tubing. In a system using a riser, the return fluid line may be the riser or a separate line carried by the riser. The tubing may be coiled tubing with a drilling motor in the bottom hole assembly driving the drill bit.

Abstract: A bus system which includes two or more voltage-to-current transformers, a common bus, a terminal bus coupled to a voltage source, two or more first switches, and a selection circuit. Each of the voltage-to-current transformers converts a voltage signal to a current signal. The common bus carries the current signals from the voltage-to-current transformers to an output bus. Each of the first switches has a first position where an output from one of the voltage-to-current transformers is coupled to the common bus and a second position where the output is coupled to the terminal bus. The selection circuit is coupled to each of the first switches and controls movement of each of the first switches between the first and second positions.

Abstract: The removal of certain reaction impurities in the manufacture of polysulfone polymers has been found to reduce the undesirable coloration in the final resin. Control of synthesizing reactions, manufacturing processes, and/or purification of specific ingredients assists in the removal of specific, undesirable impurities. The yellowness index, as determined by ASTM D1925 or ASTM E313, in the commercial grades of polysulfone resins has consistently been well above 1.0 for commercial polysulfone resins. The present invention provides polysulfone polymers after processing (e.g., injection molding) where the yellowness index is below 1.00, below 0.75, below 0.50, and even below 0.25.

Abstract: An LCC inspecting device includes a mirror having non-parallel front and rear surfaces, and reflective coatings on the front and rear surfaces. The reflective coatings reflect light of frequencies different from each other such that light of a first frequency reflects off the front surface of the mirror and light of a second, different frequency reflects off the rear surface. The LCC device may therefore be inspected from different angles by selectively using light of the first and second frequencies.

Further, the invention includes multi-segment coiled tubing drill strings that can be adapted to drilling requirements in a deep wellbore.

Abstract: A motor vehicle headlight comprises a single light source cooperating with fixed optical means to produce a fixed beam which is generally spread widthwise and which is such as to perform two functions selectively, namely to enhance a dipped passing beam produced by another headlight and to produce a further beam, such as a foglight beam, with a specific top cut-off. The beam comprises at least two regions which are bounded by at least two portions of the top cut-off line, these portions being arranged at different levels. The invention also relates to a pair of headlights of this type, one on the right of the vehicle and one on the left.
