Abstract: The disclosure provides methods for treating negative, positive, and general symptoms of schizophrenia in patients using long-acting, injectable antipsychotic drugs. The disclosure provides methods of treating a negative symptom in a schizophrenic patient in need thereof by administering to the patient a therapeutically effective amount of a risperidone composition; wherein the risperidone composition comprises about 120 mg of risperidone base.

Abstract: One particular implementation conforming to aspects of the present invention takes the form of a method for tracking the stability of a data set for multiple observers. More particularly, a tracker object may be used to both mark a particular state of the data and to query if the data remains unchanged. Code that accesses the data set to calculate a result may fetch a reference to a current tracker object associated with the data set. The code may compare the current tracker object received from the data set against the tracker object associated with the last cached result. In an alternate arrangement, a state may be associated with the data set to indicate some characteristics of the data set. The state value associated with the data set may further simplify the action required by a code accessing the data set to receive an accurate calculation.

Abstract: A method of performing a blending operation between a first pixel having a first pixel alpha value and a first pixel color data value and a second pixel having a second pixel alpha value and a second pixel color data value using a pre-defined set of logical operations and an associated set of pre-computed constant that includes calculating a first pixel blending factor and a second pixel blending factor based upon a selected Porter-Duff compositing equation, the first pixel alpha value, and the second pixel alpha value, such that there are no decisions to be made in an innermost calculation loop.

Abstract: A window guard for a window opening to prevent a child or animal from passing through a window. The window guard includes side frames fastened to the sides of a window frame and a plurality of spaced-apart, transverse, tubular, width-adjustable crosspiece elements to form a grid pattern between the side supports to prevent passage of a child or animal. The crosspiece elements include user-removable, tension-biased, locking clips at each end, to lock the crosspiece elements in a locking position, but to permit easy removal, when required.

Abstract: A variable inverted pulley circumference mechanism supported by an external mechanism that locates the pulley halves. Power transfer takes place via either a combination of a variable pulley located inside the variable inverted pulley, working together with fixed planet wheels, or with innovative variable span planet mechanisms working together with a traditional sun wheel or a variable pulley in place of a traditional sun, wherein the variable circumference mechanism consist of one or more surfaces, so that part of the surface is used as needed to form the circumference, and unused parts of the surface is stored opposite of a contact surface of the circumference.

Abstract: A compact, reliable lightweight variable diameter drive mechanism for use with either a belt or a chain comprising outwardly biased, frusto-conical axially movable pulley halves and an automatically adjustable, flexible contacting surface wrapped around the pulley axle. The contacting surface is capable of imparting significant amounts of traction to the belt or the chain riding on the pulley halves. The contacting surface automatically varies its circumference as the pulley diameter changes. Tension on the flexible contacting surface is maintained by retracting one end into the hub of the pulley as the pulley halves are axially adjusted.

Abstract: Disclosed are epoxy resin compositions comprising at least one polyglycidyl derivative of an aminophenol having the structure ##STR1## and at least one biphenyl anhydride having the structure ##STR2## wherein m is 1 or 2; wherein A is selected from the group consisting of ##STR3## WHEREIN EACH R.sup.o is individually a monovalent radical selected from the group consisting of hydrogen, halogen, hydroxy, alkyl radical having from 1 to 5 carbon atoms, alkoxy radical having from 1 to 5 carbon atoms and ##STR4## wherein R.sup.1 is an alkyl radical having from 1 to 5 carbon atoms; and wherein each R.sup.2 is individually a monovalent radical selected from the group consisting of hydrogen, halogen, alkyl radical having from 1 to 5 carbon atoms, --NO.sub.2, --COOH --SO.sub.3 H, and --NH.sub.2. The compositions are useful in such applications as molding resins, laminates, adhesives, coatings, and the like.
