Inglefield clips, from a Royal Navy handbook of 1943 Two brass Inglefield clips connected (a standard clip on the left and a swivel clip on the right).. The Inglefield clip (also known as a sister clip [1] and a Brummel hook [2]) is a clip for joining a flag or ensign quickly, easily and securely to flag halyards so that the flag can be hoisted. [3]
A horn cleat is the traditional design, featuring two “horns” extending parallel to the deck or the axis of the spar, attached to a flat surface or a spar, and resembling an anvil. A cam cleat in which one or two spring-loaded cams pinch the rope, allowing the rope to be adjusted easily, and quickly released when under load.

Used to repeat the third flag of a hoist later within the same hoist. Code/Answer Pennant: At the dip (about half-way up the halyard): Ready to receive message Close up: Message has been received and understood (the flag is then hauled back at the dip to receive the next hoist) Hauled down: Signals end of message. With numerals: Decimal point
A designator flag is used to indicate if a flaghoist signal is meant to be interpreted as an ICS signal or as a naval signal. The U.S. Navy uses a set of 68 flags, including flags for each letter of the alphabet and each numeral to convey messages of tactical or administrative nature.

a = 543.102 0504(89) × 10 −12 m, corresponding to a resolution of ΔL/L ≈ 3 × 10 −10. Similar techniques can provide the dimensions of small structures repeated in large periodic arrays like a diffraction grating. [15] Such measurements allow the calibration of electron microscopes, extending measurement capabilities.
Common sizes are from 9 ⁄ 16 to 10 ⁄ 16 inch (14 to 16 mm) square and 5 + 1 ⁄ 2 to 6 inches (140 to 150 mm) long. [10]: 582–583 A rail spike is roughly chisel-shaped and with a flat edged point; the spike is driven with the edge perpendicular to the grain, which gives greater resistance to loosening. [11]
