Abstract: A strobe light curing apparatus which includes trigger electronics for producing a series of pulses at a predetermined frequency. A flash lamp is coupled to the trigger electronics for producing flashing light according to the series of pulses. A reflector is further disposed from the lamp at a first predetermined distance for reflecting and focusing the flashing light at a second predetermined distance.

Abstract: A pliable dispensing bag containing a flowable material includes an internal rigid adapter plate having an offset or asymmetric integral nozzle through which the flowable material may be extruded. The deformable material of the bag is clamped around a collar provided at the base of the nozzle so as to form a permanent first leakproof seal. Additional material from the foil bag is gathered at the top of a cap fitted over the nozzle and clamped against the top of the cap to form a removable or temporary second seal and to further hold the cap in place on the nozzle.

Abstract: A disinfectant and flush system for a dental waste evacuator comprises a container filled with disinfectant and connected to the interior of a main flow tube of the evacuator, positioned between a disposable mouth piece and a suction source. A control valve is installed between a tubing leading from the disinfectant container and the main flow tube, which ensures that the disinfectant is admitted into the main flow tube during operation of the evacuator to flush the tube continually or intermittently.
