A Philadelphia rod consists of two sliding sections graduated in hundredths of a foot. On the front of the rod the graduation increasing from zero at the bottom. On the back of the rod the graduation decrease from 13.09 ft at the bottom to 7 ft. The division of the device in two sliding sections are devised for ease of transport.
Greenlee is an American industrial and electrical tool company headquartered in Rockford, Illinois.It was founded in 1862 by twin brothers Robert L. and Ralph S. Greenlee to manufacture their invention called a hollow chisel mortiser, consisting of a drill surrounded by four chisel blades used in making mortises (the hole) for mortise and tenon joints, for the furniture industry in Rockford.

Diagram of spray-up process. Spray-Up also known as chop method of creating fiberglass objects by spraying short strands of glass out of a pneumatic gun. This method is used often when one side of the finished product is not seen, or when large quantities of a product must be made cheaply and quickly with moderate strength requirements. [1]
Two often used types are reciprocating (hand-over-hand) and continuous (cat-track). For the radius pultrusion process the layout of the machines has two moving stages similar to the hand over hand pulling unit, but as the process is intermittent with only one puller and the mould mounted on the stage of other one.
The structure has a (1-2) coordinate system. The material has a (x-y) principal coordinate system. For fiber-reinforced composite, the fiber orientation in material affect anisotropic properties of the structure. From characterizing technique i.e. tensile testing, the material properties were measured based on sample (1-2) coordinate system.
is the angle between the slope line and the horizontal line, s is the slope distance measured between two points on the slope line, h is the height of the slope. = + Where L= Inclined length measured A= Inclined angle
Continuous filament winding machines are usually 2 axis machines capable of laying fibre, fiberglass cloth, veil in a continuous hoop pattern. These machines are usually equipped with multiple chopper motors (to impart multi directional fibre placement on the part) and sand hoppers (to drop sand onto the part and impart a structurally ...
The point machine (in this case an electric motor) and associated mechanism used to operate this switch can be seen to the right in the picture. A point machine (also known as a point motor, switch machine or switch motor) is a device for operating railway turnouts especially at a distance.
