Coloured lights are often requisite to distinguish cuts or sectors, and should be shown from fixed or occultinglight apparatus and not from flashing apparatus.
Apparatus falling under the first category produce a fixed light, and further distinction can be provided in this class by mechanical means of occultation, resulting in the production of an occulting or intermittent light.
These lights are also fitted withocculting screens on the Lindberg system.
An improvement upon the foregoing is the Benson-Lee lamp, in which a similar occulting arrangement is often used, but the illuminant is paraffin consumed in a special burner having carbon-tipped wicks which require no trimming.
The illuminant is oil gas, with an occulting characteristic.
Fixed-light optics are employed to meet such cases, and are generally fitted with occulting mechanism.
The apparatus may exhibit a fixed light or, more usually, an occulting characteristic is produced by the revolution of screens actuated by spring clockwork around the burner.
For occultingapparatus either weight clocks or spring clocks are employed.
An occulting apparatus in general use consists of a cylindrical screen, fitting over the burner, rapidly lowered and raised by means of a cam-wheel at stated intervals.
Where sectors are requisite, occulting apparatus should be adopted for the main light; or subsidiary lights, fixed or occulting, may be exhibited from the same tower as the main light but at a lower level.
Many lights are provided with occulting apparatus actuated by the gas passing from the reservoir to the burner automatically cutting off and turning on the supply.
The occulting bright light covers the fairway, and is flanked by sectors of occulting red and green light marking dangers and intensified by vertical condensing prisms.
Many fixed, occultingand flashing lights fitted with these burners are established in France and other countries.

After dinner that night they were abreast of the Gulf Rock, and Brand pointed out to his wife its occulting gleam from afar.
Since his first term of service on the rock the light had changed from an occulting to a fixed one.
The monotonous ticking of the clockwork attachment that governed it, the sharp and livelier click of the occulting hood's machinery, were the only sounds which alternated with its deep boom.
In the old days we used to depend on occulting lights, but now, flashing lights are much more powerful.
An occulting light means that some of the time the light is shut off, and at others it isn't.
As the light for which the decoy was intended to be a substitute was quite a powerful light, with a regular occulting flash, the decoy itself must be powerful, and the Miami was anxious to trace it.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "occulting" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: darkening; overcast; shading; shadowing
