Orphan date September 2008 The Compound shutter is a mechanical leaf shutter for photographic camera s introduced in the late 19th century, usually used between lens components. A typical Compound shutter may have settings for T Time , B Bulb , and times from 1 second down to 1 100th or less. Unlike later mechanical shutters such as the Compur which use a clockwork mechanism, shutter timing is achieved by releasing air from a small cylinder typically mounted horizontally at the top of the shutter through a small aperture. A cam turned by the shutter speed dial positions a piston in the cylinder to provide the correct exposure. When the shutter release is pressed the shutter opens and air in the cylinder is gradually released, letting the piston move it closes the shutter when it reaches the end of its travel. The piston travels for a very short distance at the higher speeds, making their accuracy very sensitive to the precise manufacturing of the cam lower speeds are more reliably accurate. http www.skgrimes.com compound index.htm Compound Shutters for Large Format Photographers photography stub Category Photographic shutters ... more details

Merge Unique key date August 2009 In Data modeling database design , a compound key is a key that consists of 2 or more attributes that uniquely identify an entity occurrence. Each attribute that makes up the compound key is a simple key in its own right. This is often confused with a composite key whereby even though this is also a key that consists of 2 or more attributes that uniquely identify an entity occurrence, at least one attribute that makes up the composite key is not a simple key in its own right. An example might be an entity that represents the modules each student is attending at University. The entity has a studentId and a moduleCode as its primary key. Each of the attributes that make up the primary key are simple keys because each represents a unique reference when identifying a student in one instance and a module in the other. In contrast, using the same example, imagine we identified a student by their firstName lastName. In our table representing students on modules our primary key would now be firstName lastName moduleCode. Because firstName lastName represent a unique reference to a student, it is not a simple key, it is a combination of attributes used to uniquely identify a student. Therefore the primary key for this entity is a composite key. No restriction is applied to the attributes regarding their initial ownership within the Data modeling data model . This means that any one, none, or all, of the multiple attributes within the compound key can be foreign key s. Indeed, a foreign key may itself be a compound key. Compound keys almost always originate from Attributive table attributive or Associative table associative entities tables within the model, but this is not an absolute.

It may also be known as compound coating , or chocolatey coating when used as a coating for candy.

It costs less than chocolate, as it uses less expensive hard vegetable fat s and tropical fats such as coconut oil and palm kernel oil in place of the more expensive cocoa butter as its fat source. Cocoa butter must be tempered to maintain gloss and coating.
