If the paper looked in a bad condition it could be removed by warming up the armature near a flame and replacing it. Chatterton s Compound was used in the manufacture of pneumatic pipe organs to seal lead tubing into wooden blocks for the pneumatic action. It is still used in historical restoration jobs for this purpose but has been replaced with modern materials on more recent builds. It was much used by submarine Cable Technicians for various purposes around oversea telegraph offices prior to the 1960s for general adhesive purposes and was available in round black sticks of about 3 4 inch diameter which responded to heat from a spirit lamp.

As a result, some once famous brand s such as APC For aspirin, phenacetin, and caffeine and Bex have either disappeared, or have become brand s of simple analgesics.

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.

Unreferenced date October 2008 Compound chocolate is a less expensive non chocolate product replacement made from a combination of cocoa, vegetable fat, and sweeteners. It may also be known as compound coating , or chocolatey coating when used as a coating for candy. Often used in lower grade candy bar s, compound chocolate is designed to simulate enrober enrobed chocolate on a product. 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. A baker tempers chocolate by cooling the chocolate mass below its setting point, then re warming the chocolate to between 31 C and 32 C for milk chocolate, or between 32 C and 33 C for semi sweet chocolate .

Image Spiro 5.5 undecan.svg right spiro compound A spiro compound is a bicyclic organic compound with rings connected through just one atom. The rings can be different in nature or identical. The connecting atom is also called the spiroatom , most often a quaternary carbon spiro carbon . All spiro compounds have the infix spiro followed by square brackets containing the number of atoms in the smaller ring and the number of atoms in the larger ring excluding the spiroatom itself the numbers being separated by a dot. For example compound A is called 1 bromo 3 chlorospiro 4.5 decan 7 ol and compound B is called 1 bromo 3 chlorospiro 3.6 decan 7 ol . The spiro compound consisting of a cyclohexane ring and a cyclopentane ring is called spiro 4.5 decane . This IUPAC nomenclature nomenclature was proposed by Adolf von Baeyer in 1900 Ref Baeyer .
