Abstract: The invention comprises a circuit arrangement with a first degree voltage to an alternating voltage transforming unit, a said alternating voltage to a second direct voltage transforming unit, and a said second direct voltage smoothing filter, connectable to a load, whereby said first direct voltage to an alternating voltage transforming unit presents an inductance whose one connection is connected to a connecting point which is mutual for two series connected rectifying means, and where said alternating voltage to a second direct voltage transforming unit comprises parallel related rectifying means.  A back current through one of two parallel related rectifying means, formed at the switching period of the alternating voltage, and a therefrom originating power contribution to said inductance, is redistributed by a power contribution redistributing organ, belonging to said transforming unit, in order to reduce the losses appearing, for instance, in said series connected rectifying means.

Title: Concentric annular ring lens designs for astigmatism
Inventor: ROFFMAN JEFFREY H
IPC: G02C7/02
Filed: 1996-05-02
Granted: 2001-02-13
Abstract: Concentric annular ring lens designs are disclosed for astigmatic patients, particularly lens designs which reduce the sensitivity of the patient to toric axis misalignment, thus reducing the required number of stock keeping units in inventory for a toric product.  Several of the concentric annular ring lens designs comprise a multifocal concentric annular ring design on either the front or back surface and a toric curve on the reverse surface to correct for astigmatism. Alternating concentric annular rings divide the optical zone of the contact lens into regions having at least two optical powers, a first optical power corresponding to the refractive spherical component of a patient's basic prescription Rx, and a second optical power corresponding to the cylindrical power of a patient's basic prescription Rx, or a portion thereof, with an optional third intermediate optical power, such that the multifocus toric lens is rotationally desensitized because of the enhanced depth-of-field provided by the plurality of concentric annular rings.  Some embodiments of the present invention have a spherical front or back surface wherein the opposite surface has a plurality of toric annular rings.  Some embodiments of the present invention eliminate a toric surface, prism ballast and slab-off features, and provide spherical optical powers at the basic prescription Rx spherical power, the cylindrical power prescription Rx, and an intermediate optical power intermediate to the spherical and cylindrical optical powers.

Abstract: The plant comprises an adsorbent-filled tank permanently interposed in a line between a purification unit operating by adsorption of solidifiable impurities from a gas mixture containing carbon monoxide, and a cryogenic separation unit which delivers pure carbon monoxide at its outlet. The adsorbent in the tank advantageously the same as the adsorbent in the adsorbers of the purification unit has an affinity for carbon monoxide, thus making it possible to reduce the cyclic variations in the carbon monoxide production delivery rate which results from the cyclic operation of the adsorbers of the separation unit. This plant permits a simple, efficient and inexpensive regulation of the carbon monoxide production in such a plant, while greatly limiting production losses.

Abstract: A valueless four-stroke internal combustion engine employs an intake piston and an exhaust piston that reciprocate within intake and exhaust cylinders disposed adjacent the combustion chamber of the engine. A power piston reciprocates within a cylinder that defines a portion of.the combustion chamber. An intake port opens into the intake cylinder, and an exhaust port opens into the exhaust cylinder. Upon reciprocation of the intake and exhaust pistons, the exhaust ports will be covered and uncovered. By coordinating movement of the intake and exhaust pistons with reciprocation of the power piston, a combustible fuel-air mixture will be drawn into the combustion chamber, ignited, and exhausted. The timing and extent of movement of the intake and exhaust pistons can be controlled by a crankshaft or cams.

Abstract: Untreated wood chips are fed to treatment, e.g. steaming at substantially atmospheric pressure, using a mechanical conveyor. Steaming may be accomplished utilizing a vertical chip bin with one dimensional convergence and side relief fed by a horizontal conveyor (e.g. screw conveyor) having a physical restriction which insures formation of a chip plug to prevent leakage of gas through the conveyor housing inlet. The physical restriction may be a generally vertical hinged plate, with an opening containing elastomeric material through which the shaft of the conveyor may pass, or a stationary generally vertical plate with one or more openings, which openings also may be covered with yielding flexible material and with the degree of sealing provided controlled by the speed of rotation of the conveyor shaft.
