T bevel with protractor and dividers In use. A sliding T bevel, also known as a bevel gauge or false square [1] is an adjustable gauge for setting and transferring angles. . Different from the square, which is fixed and can only set a 90° angle, the sliding T bevel can set any angle and transfer it on anoth
A gauge block accessory set A holder that turns a stack of gauge blocks into an instant, custom caliper or go/no go gauge.. The pictured accessories provide a set of holders and tools to extend the usefulness of the gauge block set.
[1] [2] Other names for the tool include adjustable square, combo square, and sliding square. The most common head is the standard head, which is used as a square for marking and testing 90° and 45° angles. [3] The other common types of head are the protractor head, and the centre finder head. [4]
[1] [2] He was granted his first Swedish patent on 2 May 1901, Swedish patent No. 17017 called "Gauge Block Sets for Precision Measurement".

A particular choice of the scalar and vector potentials is a gauge (more precisely, gauge potential) and a scalar function ψ used to change the gauge is called a gauge function. [citation needed] The existence of arbitrary numbers of gauge functions ψ(r, t) corresponds to the U(1) gauge freedom of this theory. Gauge fixing can be done in many ...
