Abstract: A system and method are used to identify a targeted consumer. The system includes a partial social security number (SSN) system that identifies a partial SSN issued during a preselected time period and a marketing database system. The marketing database system receives a comparison result from a SSN matching system that identifies at least one individual in a consumer database having a partial SSN that matches the partial SSN identified by the partial SSN system. The marketing database system places identifying information of the at least one individual in a marketing database. In one method, an individual is identified as a targeted consumer based on the individual's age being within a preselected age range and the individual's social security number being issued within a predetermined social security number SSN issue date range. Identifying information of the targeted consumer is stored in a contact database, which a business may use to directly market its goods or services.

Abstract: A toy vehicle comprises a lift mechanism which allows the toy vehicle to be lifted from a support surface in a lifting motion and roll end over end over end. The lift mechanism includes a lift arm pivotally mounted to a housing of the toy vehicle. A lift arm actuating motor is coupled to a lift arm drive screw that is in threaded engagement with a lift arm drive nut. A strut is coupled between the drive nut and the lift arm. In operation, the lift arm actuating motor drives the lift arm drive screw and causes the lift arm drive nut to drive the strut and move the lift arm into an extended position, causing the lift arm to engage a support surface to lift the toy vehicle. In the extended position, the toy vehicle is sufficiently rounded to permit the vehicle to roll end over end over end.

Abstract: Provided herein are catalysts useful in the curing of cementitious mixtures, which catalysts comprise one or more alkylene carbonates in combination with glycerin carbonate. Through use of a catalyst according to the present invention, cementitious mixtures containing sodium silicate may be cured at low temperatures because the catalysts of the invention function well at low temperatures, even though they contain ethylene carbonate, a material whose melting point of 36° C. otherwise precludes its use as a cure accelerant for silicates. FIG. 1 is a graphical representation of the results shown in Table II.
