Gear case

A gear case, also known as a chain case or chainguard, is an enclosure for the bicycle chain and sprocket assemblages commonly employed by utility bicycles. It serves to protect the cyclist from being soiled or trapped in the chain rings and tends to fully enclose the drive train. It may also contain an oil bath to keep the chain lubricated. Modern examples are usually moulded in plastic. Similar devices may be found in connection with chains used on larger vehicles and machinery.

    A legal case is a dispute between opposing parties resolved by a court, or by some equivalent legal process. A legal case may be either civil or criminal. There is a defendant and an accuser.

    A civil case

    A civil case, more commonly known as a lawsuit or controversy, begins when a plaintiff files a document called a complaint with a court, informing the court of the wrong that the plaintiff has allegedly suffered because of the defendant, and requesting a remedy. A civil case can also be arbitrated through arbitration. The remedy sought may be money, an injunction, which requires the defendant to perform or refrain from performing some action, or a declaratory judgment, which determines that the plaintiff has certain legal rights. Whoever wins gets either released from custody or gets nothing (Accuser).

    The plaintiff must also make a genuine effort to inform the defendant of the case through service of process, by which the plaintiff delivers to the defendant the same documents that the plaintiff filed with the court.

    Grammatical case

    Case is a grammatical category whose value reflects the grammatical function performed by a noun or pronoun in a phrase, clause, or sentence. In some languages, nouns, pronouns, and their modifiers take different inflected forms depending on what case they are in. English has largely lost its case system, although case distinctions can still be seen with the personal pronouns: forms such as I, he and we are used in the role of subject ("I kicked the ball"), whereas forms such as me, him and us are used in the role of object ("John kicked me").

    Languages such as Ancient Greek, Armenian, Latin, Sanskrit, Hungarian, Turkish, Tamil, Russian, Polish, Ukrainian, Serbo-Croatian, Czech, Slovak, Finnish, Icelandic, Latvian and Lithuanian have extensive case systems, with nouns, pronouns, adjectives, and determiners all inflecting (usually by means of different suffixes) to indicate their case. A language may have a number of different cases (Turkish and Romanian have five, Latin and Russian each have at least six; Armenian, Polish, Czech, Ukrainian, Serbo-Croatian, Latvian, and Lithuanian have seven; Finnish has fifteen and Hungarian has eighteen). Commonly encountered cases include nominative, accusative, dative, and genitive. A role that one of these languages marks by case will often be marked in English using a preposition. For example, the English prepositional phrase with (his) foot (as in "John kicked the ball with his foot") might be rendered in Russian using a single noun in the instrumental case, or in Ancient Greek as τῷ ποδί, tōi podi, meaning "the foot" with both words (the definite article, and the noun πούς, pous, "foot") changing to dative form.

    Joseph Case

    Joseph ben Abraham Case (also Casa or Kaza; Hebrew: יוסף בן אברהם קאזי or קאזא) was one of the foremost Polish rabbis and Talmudists of the end of the sixteenth century and the beginning of the seventeenth; died at Posen about 1610. His name, "Case" or "Kaza" is most probably only a variant of the well-known surname "Cases." This would argue for Italian descent; but it does not agree with the fact that Case called himself "Shapiro," as Bloch has conclusively proved.

    After serving as chief rabbi of Lemberg, Case became city rabbi of Posen, while Mordecai ben Abraham Jafe was the district rabbi of Greater Poland. Although Case apparently left no writings, he was one of the first Talmudic authorities of his time, as may be seen from Benjamin Aaron Solnik's responsum No. 22, and Meïr ben Gedaliah of Lublin's responsum No. 88. Case's son Solomon (died January 2, 1612, at Lemberg) was also an eminent Talmudist.

    A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. Two or more gears working in a sequence (train) are called a gear train or, in many cases, a transmission; such gear arrangements can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a linear toothed part, called a rack, thereby producing translation instead of rotation.

    The gears in a transmission are analogous to the wheels in a crossed belt pulley system. An advantage of gears is that the teeth of a gear prevent slippage.

    When two gears mesh, and one gear is bigger than the other (even though the size of the teeth must match), a mechanical advantage is produced, with the rotational speeds and the torques of the two gears differing in an inverse relationship.

    Gear (comics)

    Gear (real name: I.Z.O.R.) is a fictional character a superhero in the DC Comics universe. The character is a member of the Legion of Super-Heroes in the future.

    Fictional character biography

    Gear is a Linsnarian (named for Joseph Michael Linsner?), a race composed of organic machinery beneath humanoid shells. The Blackstar Juvenile Correctional Facility captured him for use in maintaining their systems. For quite some time, he pretended to be servile, while programming some of his machinery to disable the systems keeping the inmates contained and powerless upon his deactivation. On the arrival of the Legionnaire Sensor on the station, he was convinced by her to move prematurely, and was severely damaged in the process, activating his failsafes.

    However, Brainiac 5 successfully repaired him, and Gear remained on the Legion Outpost space station until most of the Legion was lost in a rift and the team was forcefully disbanded as a result. R.J. Brande then made contact with many of the remaining Legionnaires, including Gear, and put together a plan to construct a "Legion World" - an artificial planetoid to house a revived and expanded team, which Gear and Invisible Kid designed and helped to construct.
