Hook (wall)
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved/bent back or has a deeply grooved indentation, which serves to grab, latch or in any way attach itself onto another object. The hook's design allows traction forces to be relayed through the curved/indented portion to and from the proximal end of the hook, which is either a straight shaft (known as the hook's ''shank'') or a ring (sometimes called the hook's "''eye''") for attachment to a thread, rope or chain, providing a reversible attachment between two objects. In many cases, the distal end of the hook is sharply pointed to enable penetration into the target material, providing a firmer anchorage. Some hooks, particularly fish hooks, also have a ''barb'', a backwards-pointed projection near the pointed end that functions as a secondary "mini-hook" to catch and trap surrounding material, ensuring that the hook point cannot be easily pulled back out once embedded in the ...

Fish Hook
A fish hook or fishhook, formerly also called an angle (from Old English ''angol'' and Proto-Germanic ''*angulaz''), is a hook used to catch fish either by piercing and embedding onto the inside of the fish mouth (angling) or, more rarely, by impaling and snagging the external fish body. Fish hooks are normally attached to a line, which tethers the target fish to the angler for retrieval, and are typically dressed with some form of bait or lure that entices the fish to swallow the hook out of its own natural instinct to forage or hunt. Fish hooks have been employed for millennia by fishermen to catch freshwater and saltwater fish. There is an enormous variety of fish hooks in the world of fishing. Sizes, designs, shapes, and materials are all variable depending on the intended purpose of the hook. Fish hooks are manufactured for a range of purposes from general fishing to extremely limited and specialized applications. Fish hooks are designed to hold various types of arti ...

Rehabilitation for someone with an amputation is primarily coordinated by a Physical medicine and rehabilitation, physiatrist as part of an inter-disciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists. Prostheses can be created by hand or with computer-aided design (CAD), a software interface that helps creators design and analyze the creation with computer-generated Technical drawing, 2-D and 3D computer graphics, 3-D graphics as well as an ...

Mail Hook
] A catcher pouch is a mail bag that can be used in conjunction with a mail hook to "catch" mail awaiting pickup from a moving train. Catcher pouches were most often used by railway post offices in the nineteenth century and the early twentieth century. Its use was limited to exchanges onto moving trains. The specially constructed catcher pouch was grabbed by the catcher mechanism in the passing railway car and the catcher pouch would release from the holding rings on the mail crane. This technique was known as "mail on the fly". Starting in the 1870s the use of this technique of the Railway Mail Service was an important issue in the United States. It was a popular technique and the backbone of the United States Postal Service through the 1930s.As the United States Postal Service undergoes its fiscal crisis in the second decade of the 21st century, it is well to note that these are not entirely new problems.

Hook-and-loop Fastener
Hook-and-loop fasteners, commonly known as Velcro (a Generic trademark, genericized trademark), hook-and-pile fasteners or touch fasteners are versatile fastening devices that allow two surfaces to be repeatedly attached and detached with ease. Invented in the mid-20th century, they are widely used in clothing, accessories, and various industrial and consumer applications. The fastener consists of two complementary components: one with tiny hooks and the other with soft loops. When pressed together, the hooks catch the loops, creating a secure but temporary bond. The fasteners can be separated by peeling or pulling the surfaces apart, often producing a distinctive ripping sound. History The original hook-and-loop fastener was conceived in 1941 by Swiss engineer George de Mestral, which he named velcro.The word Velcro is a portmanteau of two French words: "velours" meaning velvet, and "crochet" meaning hook. The idea came to him one day after he returned from a hunting trip wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
