Smart slide

A furnace system comprising:

• a sliding style furnace cap having a furnace tube cap and a slider;
• the furnace tube cap having a first cap portion configured to couple to a furnace tube of a furnace, and having a second cap portion with a bearing assembly arrangement, the furnace tube cap also having an inner tube cap channel passing from the first cap portion to the second cap portion with an inner tube cap channel sealing arrangement configured to extend around the inner tube cap channel;
• and
• the slider having an orifice or channel configured therein passing through the slider, being configured to couple and slide in the bearing assembly arrangement from an inject position to a rinse position, and vice versa, having a contoured surface with a first ramp configured to couple a first raised surface and an intermediate lower surface, and with a second ramp configured to couple the intermediate lower surface to a second raised surface,
• the slider configured to move towards the inner tube cap channel and cause the bearing assembly arrangement to force a bottom part of the slider to push against the inner tube cap channel sealing arrangement as a corresponding part of the bearing assembly arrangement rides up either the first ramp to the first raised surface when the slider is moved to the inject position, or the second ramp to the second raised surface when the slider is moved to the rinse position, and to force the bottom part of the slider to seal the inner tube cap channel sealing arrangement when the slider is in either the inject position or the rinse position, and
• the slider configured to move away from the inner tube cap channel and cause the bearing assembly arrangement to allow the bottom part of the slider to float above the inner tube cap channel sealing arrangement as the corresponding part of the bearing assembly arrangement rides along the intermediate lower surface when the slider is in transition between the inject position and the rinse position.
