Legitimists

Legitimists are Royalists in France who believe that the King of France and Navarre must be chosen according to the simple application of the Salic Law. Called "Ultra-royalists" under the Bourbon Restoration, they are adherents of the elder branch of the Bourbon dynasty, overthrown in the 1830 July Revolution. Distinguished historian René Rémond analyses the legitimists as one of the three main right-wing factions in France, which was principally characterized by their counterrevolutionary opinions (they rejected the 1789 French Revolution, the Republic and everything that went with it; thus, they progressively became a far-right movement, close to traditionalist Catholics). The other two right-wing factions are, according to Rémond, the Orleanists and the Bonapartists.

yoke

A yoke is a wooden beam which is used between a pair of oxen to allow them to pull a load (oxen almost always work in pairs). It can be used to help plow fields. There are several types, used in different cultures, and for different types of oxen. A pair of oxen is also called a yoke of oxen, and yoke is also used as a verb: "to yoke a pair of oxen".

Candiru

Candiru (English and Portuguese) or candirú (Spanish), also known as cañero or toothpick fish, are a number of genera of parasitic freshwater catfish in the family Trichomycteridae; all are native to the Amazon River. Although some candiru species have been known to grow to a size of 16 inches (~41 cm) in length, others are considerably smaller. These smaller species are known for an alleged tendency to invade and parasitize the human urethra; however, despite ethnological reports dating back to the late 19th century, the first documented case of a candiru parasitizing a human did not occur until 1997.

Viscachas

Viscachas or vizcachas are rodents of two genera (Lagidium and Lagostomus) in the family Chinchillidae. They are closely related to chinchillas, and look similar to rabbits. There are five extant species of viscacha.

Manumission

Manumission is the act of a slave owner freeing his or her slaves. In the United States before the passage of the Thirteenth Amendment to the United States Constitution, which abolished slavery, this often happened upon the death of the owner, under conditions in his will.

Phrygian cap

The Phrygian cap is a soft conical cap with the top pulled forward, associated in antiquity with the inhabitants of Phrygia, a region of central Anatolia. In the western provinces of the Roman Empire it came to signify freedom and the pursuit of liberty, perhaps through a confusion with the pileus, the manumitted slave's felt cap of ancient Rome. Accordingly, the Phrygian cap is sometimes called a liberty cap; in artistic representations it signifies freedom and the pursuit of liberty.

gerotor

A gerotor is a positive displacement pumping unit. The name gerotor is derived from "Generated Rotor". A gerotor unit consists of an inner and outer rotor. The inner rotor has N teeth, and the outer rotor has N+1 teeth. The inner rotor is located off-center and both rotors rotate. The geometry of the two rotors partitions the volume between them into N different dynamically-changing volumes. During the assembly's rotation cycle, each of these volumes changes continuously, so any given volume first increases, and then decreases. An increase creates a vacuum. This vacuum creates suction, and hence, this part of the cycle is where the intake is located. As a volume decreases compression occurs. During this compression period, fluids can be pumped, or compressed (if they are gaseous fluids).

Gerotor pumps are generally designed using a trochoidal inner rotor and an outer rotor formed by a circle with intersecting circular arcs.

A gerotor can also function as a pistonless rotary engine. High pressure gas enters the intake area and pushes against the inner and outer rotors, causing both to rotate as the area between the inner and outer rotor increases. During the compression period, the exhaust is pumped out.
