1153 results about "Short length" patented technology

Short of a length (sometimes referred to as "back of a length" or "short of a good length") is a term used in the sport of cricket. It describes a delivery from the bowler that pitches short of the optimum length.

Fiber optic storing and dispensing apparatus

Storage and dispensing apparatus for use with a unitary length of coilable fiber optic cable having a minimum bending radius, such apparatus having a casing within which is journaled a rotatable spool having two grooves in which relatively long and relatively short lengths of the cable may be coiled. One end of the cable is coupled to a connector that is releasably retained on the spool for rotation therewith. The opposite end of the cable is joined to a connector which is extendible from and retractable into the casing in which the spool is journaled. The casing is formed of rigid plastic material which protects the cable against damage from externally applied forces. No part of the cable within the casing is subject to being bent about a radius less than the minimum bending radius.

Mode-locked multi-mode fiber laser pulse source

A laser utilizes a cavity design which allows the stable generation of high peak power pulses from mode-locked multi-mode fiber lasers, greatly extending the peak power limits of conventional mode-locked single-mode fiber lasers. Mode-locking may be induced by insertion of a saturable absorber into the cavity and by inserting one or more mode-filters to ensure the oscillation of the fundamental mode in the multi-mode fiber. The probability of damage of the absorber may be minimized by the insertion of an additional semiconductor optical power limiter into the cavity. To amplify and compress optical pulses in a multi-mode (MM) optical fiber, a single-mode is launched into the MM fiber by matching the modal profile of the fundamental mode of the MM fiber with a diffraction-limited optical mode at the launch end, The fundamental mode is preserved in the MM fiber by minimizing mode-coupling by using relatively short lengths of step-index MM fibers with a few hundred modes and by minimizing fiber perturbations. Doping is confined to the center of the fiber core to preferentially amplify the fundamental mode, to reduce amplified spontaneous emission and to allow gain-guiding of the fundamental mode. Gain-guiding allows for the design of systems with length-dependent and power-dependent diameters of the fundamental mode. To allow pumping with high-power laser diodes, a double-clad amplifier structure is employed. For applications in nonlinear pulse-compression, self phase modulation and dispersion in the optical fibers can be exploited. High-power optical pulses may be linearly compressed using bulk optics dispersive delay lines or by chirped fiber Bragg gratings written directly into the SM or MM optical fiber. High-power cw lasers operating in a single near-diffraction-limited mode may be constructed from MM fibers by incorporating effective mode-filters into the laser cavity. Regenerative fiber amplifiers may be constructed from MM fibers by careful control of the recirculating mode. Higher-power Q-switched fiber lasers may be constructed by exploiting the large energy stored in MM fiber amplifiers.

Wine rack and kit and method for its onsite assembly

InactiveUS6763956B2Readily and economically and expeditiously fabricated offsiteAssembled inexpensively and rapidlyBottle cupboardsFolding cabinetsSheet steelShortest distance
Disclosed is a wine rack, large versions of which are adapted to be installed against a wall of a room or as a free standing wall separated from the walls of a room, which is a monolithic flat rigid sheet to which has uniformly mounted in rows through holes therein a like number of wine bottle support rods which project perpendicularly and parallel to each other from one or both faces of the sheet so that two wine bottles of varying sidewall diameter can be stored on three of the rods without their side-walls touching and whose essential elements can be fabricated offsite by forming uniform rows of holes in a monolithic sheet of stainless steel; fitting in the holes machine bolts whose threaded shank ends project beyond a face of the steel sheet; bonding the heads of the bolts to the opposite face of the steel sheet so that their threaded ends project axially perpendicularly, rigidly and parallel to each other; and forming a female threaded cavity in one end of a plurality of wine bottle support rods. The thus-fabricated structural parts of the wine rack are then transported to the installation site, where the rods are coupled to the projecting ends of the bolts. A plurality of the thus-fabricated wine rack are mounted side-by-side vertically on a wall of a room at the installation site or one of them can be installed as free standing version which is stabilizing from bending or swaying at its base. A free standing version with wine bottle support rods projecting from both faces thereof can similarly be produced using short lengths of threaded steel rods which, when inserted in the holes in the steel sheet, its ends project a short distance beyond each face of the steel sheet so that the internally female threaded ends wine bottle support rods can be mounted on both ends thereof.
