SPECIAL TYPES OF MOTORS: (CLASS 318)
The several designations applied to distinguish the several types of motors such as series motors, induction motors, synchronous motors, etc., shall apply to those motors whose normal running characteristics are so described. Thus a synchronous motor is one which runs as a synchronous motor under normal running or load conditions. This is true even though the motor may be driven by some other device either (mechanical or electrical) during the starting and/or accelerating period or may operate on some other motor principle during the starting or accelerating period. Such an instance may be illustrated by a synchronous motor which is provided with means to cause it to start as an induction motor and subsequently and normally run at synchronous speed. Such a motor is considered to be a synchronous motor, since under normal running conditions, it exhibits all the characteristics of a synchronous motor.

Examples of specifically structured single materials are Raney nickel and activated carbon.

SPECIFIED INTERMEDIATE CONDENSATION PRODUCT (SICP) (CLASS 520)
Specified intermediate condensation product is limited to: (a) Reaction of an aldehyde or derivative and an amine or compound containing a N- or N group where R is hydrogen or hydrocarbon radical. (b) Reaction of an aldehyde or derivative and a phenolic material. (c) Reaction of an aldehyde or derivative and a ketone. (d) A compound containing a N-(-C-O-Z)n group.

X - is H, part of an ether group, or an inorganic cation. n - is two or more, a is one or more.

SPECIFIED MATERIAL (CLASS 520)
Denotes the intentional and deliberate presence of a material (other than as a reactant monomer) during the polymerization reaction, which material may be removed subsequent to the polymerization, or which may remain with or in the final desired polymeric product. The term "specified material" is limited to an amount of a material (e.g., 2 percent of a material, etc.). A recitation of at least one specified element in a compound or in elemental form (e.g., oxygen-liberating compound, peroxy compound, chlorine-containing, etc.) Groups of elements which can be identified from the periodic table, other than metal or nonmetal (e.g., Group IA, transition metal, halogen-containing, etc.) Compounds which have identified art meaning (e.g., alcohol, ethers, esters, etc.) Examples of material, which are described in mere functional terms and are thereby excluded as being a "specified material" since they do not meet the parameters set out above, are terms such as free radical catalyst, redox catalyst, emulsifier, dispersant, base, acid, organic medium, etc. Water in any of its physical forms: inert gases (Group VIIIA), hydrocarbons, and chlorinated hydrocarbons are specifically excluded from this area as being specified material even if specifically recited as to name (e.g., chloroform, etc.) or as to amount (e.g., 2 percent of chloroform, etc.). A search for these materials requires a search of the appropriate product area. However, specific provision has been made in Class 526, subclass 208 for a mixture of a chlorinated hydrocarbon and water, and in Class 526, subclass 207 for a mixture of hydrocarbon and water. Terms such as complex, coordination complex, chelate, sequestered, or adduct, and terms which are exemplary of these but which are not limited to the enumerated examples, such as sequestered complex, chelated compound, etc., are classified as are compounds, per se, when they are products of a metal or metal compound and a nonmetal organic compound. These materials are classified as separate compounds or elements when (a) the product is the reaction product of at least two or more metals, metal-containing compounds, or mixtures thereof (e.g., alloy, etc.) or (b) when the product is the reaction of at least a metal or metal compound and an inorganic material. Patents in this area are to be classified on the basis of the claimed final compound or composition that is introduced into the reaction zone and is in direct contact with any of the monomers therein. If it is not possible to so classify the introduced material, classification is then made on the basis of the individual reactants used in the preparation of the unknown material. In the event that the claims recite both the individual reactants and identify the product formed therefrom, then the original classification should be made in the subclass that provides for the known product and a cross-reference should be placed in the appropriate subclass that provides for the reactants. Patents which claim an "in situ" preparation of "specified material" in the presence of the monomer are originally classified on the basis of the introduced reactants and cross-referenced to the prepared "specified material".

SPECIFIED POLYMER-FORMING INGREDIENTS (SPFI) (CLASS 520)

The following two structures are illustrative: A structure such as: is excluded because the carbon atom shared by two rings is also shared by a third ring. The common ring member must be attached to two ring members of each of the rings by nonionic bonding. Therefore, stuctures such as: are also excluded from consideration as "spiro ring systems" because ionic bonding exists between the hetero ring atom and an acyclic atom (an oxygen atom in both of these cases) in the formation of these betaine inner salts.

SPIRO and SPIRO RING SYSTEM (CLASS 532)
These terms denote the sharing of one common ring member only by exactly two rings. The following two structures shown in Figure 17 are illustrative of spiro systems: A structure such as that of Figure 18 is not spiro because the "C" shared by the two rings is also shared by a third ring. The common ring member must be attached to two ring members of each of the rings by nonionic bonding, and nonionic bonding must exist between all members of a ring in order for the ring to be regarded as a hetero ring. Thus, the structures shown in Figures 19 and 20 are excluded from the category of "spiro ring systems" because ionic bonding exists between the nitrogen hetero ring atom and an acyclic atom (an oxygen atom in each case) in the formation of these betaine inner salts. These two structures will be considered and classified in the forms depicted, respectively, as Figures 21 and 22.
