A plain taper attachment for the lathe is illustrated in Figure7-69. A bed bracket attaches to the lathe bed and keeps theangle plate from moving to the left or the right. The carriagebracket moves along the underside of the angle plate in adovetail and keeps the angle plate from moving in or out onthe bed bracket.
The Bryozoa, also known as Polyzoa, Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals.Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a crown of tentacles lined with cilia.nother group of animals discovered subsequently, whose filtering mechanism looked similar, was also included in Bryozoa until 1869, when the two groups were noted to be very different internally. The more recently discovered group was given the name Entoprocta, while the original Bryozoa were called Ectoprocta.
As a multi-cellular creature, the bullfrog is in the kingdom Animalia, also known as Metazoa. Animalia also contains fishes, arthropods, mammals, reptiles and many others.Bullfrogs belong to the phylum Chordates, a group of creatures characterized by having a rod that extends the length of the body.The subphylum is Vertebrata, or the vertebrates and the bullfrog's class is Amphibia, the amphibians including frogs and salamanders.he American bullfrog was classed in the genus Rana from the 1800s to the early 2000s. The breakthroughs that became available to herpetologists in the early 2000s resulted in discovering closer relationships to members of another genus: Lithobates.
