An Interactive Communication System which solves the problem of enabling a participant (16) to participate in a broadcast program event (40) by using a dual-tone multifrequency (DTMF) keypad (46) on an existing telephone (18) is disclosed. The broadcast program event (40) may be viewed on a television receiver (12) simultaneously with other participants (74). A computer (22) is driven by a plurality of DTMF receivers (122). The participant (16) gains access to a DTMF receiver (122) through a conventional telephone circuit (20a) terminating at a local telephone exchange (LTE). The participant (16) is prompted by the program event (40) to enter responses into the computer (22) through the DTMF receiver (122) by pressing keys (140) on the key pad (46). The DTMF receiver (122) has a digital character output (126). A microprocessor (124) processes the output (126) and sends it to a main memory (28) when enabled by associated logic (120,121,131,132,134). Viewer identification software (25) associates the responses with the participant (16) and a time stamp (50) is attached (138). Criteria software (30) sorts and evaluates the responses according to criteria instructions (35). Judging software (32) selects a winner according to judging instructions (37). Winner(s) selection software (34) supplies winner identification for announcement by the transmitting station (38). The broadcast program event (40) may include commercial messages offering incentives to purchase merchandise and services or include offers of prizes to the participant (16).

Interactive communication system

An apparatus for injecting fluid into the crushing region of a rotary crusher, which may be either a gyratory crusher or a cone crusher, is disclosed. The injection of fluid can be through conventional nozzles, ports, or through other shapes of apertures. The injection of fluid can be on a continuous basis, on a time-modulated basis, or on a spatially modulated basis. The invention is not limited to use with a particular type of material to be crushed, nor is it limited to use with a particular type of injected fluid. Performance is improved in three areas: (a) a substantial throughput increase is achieved, (b) the output produce is more uniform and therefore of higher value than a non-uniform product would be, and (c) greater size reduction is achieved on a single pass. The invention can increase the capacity of an existing crushing installation, or enable use of a smaller crusher than would normally be required. In either case, the invention will result in a substantial cost saving as compared to crushers operating without benefit of this invention.
