Abstract: An improved method of chemical bonding wherein a bonding polymer and its corresponding curing agent are deposited on plastic strips with adhesive backings. When bonding is desired, then these strips are applied to the bondable structural surfaces and the exposed deposits are brought together through agitation, mixing the two components and initiating the bonding action.

Abstract: A community-based centralized postal delivery system which operates under the control of a slaved micro-computer. The slaved micro-computer itself being controlled by a master-computer located at the main post office. The micro-computer also being accessible and partially programmable by the postal delivery agent assigned to the postal zone. Typically, the end postal distribution point is an automated storage vault located in mid-block in a residential area. When universally addressed postage is magazine loaded into the vault by the postal delivery agent and the postal patron's mail compartment is occupied, the patron may interrogate an electronic module situated within his home to see if he has mail or facsimile material. Verification of such material is confirmed by the computerized vault returning a unique code with which the patron may access his mail porthole.

Abstract: A telephonic communications system (FIGS. 1 and 2) designed to use the availability of ordinary subscriber telephone lines to which a telephone instrument (312) is conventionally attached. Whenever it is desirable for a caller (306 or 309) to transmit data from a calling telephone (305, 308 or 316) a special code is input to the called telephone (312 or 301) which, through detection circuitry, activates an intercept system (184A of FIG. 11) within the called telephone, which inhibits audible ringing of the called telephone instrument and connects a second system (FIGS. 10 and 14) incorporated within the same called telephone instrument for auto-tuning, processing, and re-transmitting from the called telephone subsequent received data to a remote addressable portable data unit (302 or 311). The remote data units (302 and 311) communicate with the telephone instrument (301 and 312) via a radio frequency data link, through which it may either receive data from or transmit data to the telephone instrument.

Abstract: A device for electronically generating a plurality of single still pictures which are stored in the device's self-contained programmed digital memory cartridge and which is displayed on a liquid crystal screen. The device is a structure resembling a thin pocket calculator.
