These coils of heavy strong cargo rope are covered in hessian for protection from the elements and for ease of handling. They would have been imported for local use such as haulage, fencing and towing. These rope coils or bails are an example of products imported into Australia for local use.Rope; four large coils of thick rope in hessian covers.Some of the covers have remnants of paper labels and black markings.flagstaff hill, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, rope, rope coil, rope bail, cargo rope, hessian covered rope

An induction coil consists of two coils of insulated copper wire wound around a common iron core. One coil, called the primary winding, is made from relatively few (tens or hundreds) turns of coarse wire. The other coil, the secondary winding, typically consists of many (thousands) turns of fine wire. An electric current is passed through the primary, creating a magnetic field. Because of the common core, most of the primary's magnetic field couples with the secondary winding. The primary behaves as an inductor, storing energy in the associated magnetic field. When the primary current is suddenly interrupted, the magnetic field rapidly collapses. This causes a high voltage pulse to be developed across the secondary terminals through electromagnetic induction. Because of the large number of turns in the secondary coil, the secondary voltage pulse is typically many thousands of volts. This voltage is often sufficient to cause an electric spark, to jump across an air gap separating the secondary's output terminals. For this reason, induction coils were called spark coils. The size of induction coils was usually specified by the length of spark it could produce; an '8 inch' (20 cm) induction coil was one that could produce an 8 inch arc.

In an induction coil the distance between the plates is often used to measure the voltage of the spark since the air breaks down at 30 000 volts per centimetreballarat college of advanced education, scientific instrument, induction coil, scientific instruments, electricity

The “Saf-T-Coil” (Julius Schmid Laboratories, Little Falls, New Jersey, USA) IUD was a first generation IUD that entered manufacturing in 1965 and was one of the first inert type plastic IUDs to be commonly used. It was also one of the first to adopt the familiar T-shape of IUDs still used today. It was accepted during its time as being generally safe, effective and easy to insert, with low expulsion rates due to its bulky frame. Production was halted in 1982 for economic reasons as newer contraceptive methods gained popularity. (Madden et al.

The Fluotec vaporizer was made to administer only halothane (Fluothane). It was one of the first vaporizers made for use with only one anesthetic, and one of the first to use a bimetallic coil for temperature compensation.The bimetallic coil is part of the valve that controls how much of the carrier gas enters the vapor chamber to vaporize the anesthetic.Modern vaporisers still use this bimetallic coil technology today. Serial No: 5040 Patent No: 814427 A ready reference “calibration card” came attached to these vaporizers. The card was printed with a scale that indicated the concentration of halothane produced at different flow rates and dial settings.This item does not have a reference card with it.This Flotec vaporiser holds historic significance as a very good example of an early model piece of equipment for halothane only administration. Modern vaporisers still use the bimetallic coil technology and therefore this object has scientific and research significance.Small metal stand with 3 rubber feet, Main metal cylinder body housing the bimetallic coil.
