To provide a method for manufacturing a medical glass container prevented from breakage and deformation and a fire blasting device. A method for manufacturing a medical glass container includes a processing process of placing a glass container 10 on the outer peripheral surface of each of a first roller 61 and a second roller 62, which are disposed side by side in such a manner that the axis lines are parallel to each other, so that the axis line of the glass container 10 is parallel to the axis lines of the first roller 61 and the second roller 62 and the entire outer peripheral surface in an inner surface 15 of the glass container 10 corresponding to a region deteriorated by processing is made to abut on the outer peripheral surface of each of the first roller 61 and the second roller 62, and then applying a flame ejected from a point burner 30 to the region deteriorated by processing in the inner surface 15 of the glass container 10 while rotating the glass container 10 by rotating the first roller 61 and the second roller 62 around the axis lines.

Known heating burners for producing a welded joint between components of quartz glass include a burner head in which at least one burner nozzle is formed, a burner-head cooling system for the temperature control of the burner head and a supply line connected to the burner nozzle for a fuel gas. Starting from this, to modify a heating burner in such a way that impurities in the weld seam between quartz-glass components to be connected are largely avoided, it is suggested that the burner head should include a base body of silver or of a silver-based alloy.

Methods for providing feedback control of converters for converting glass tubes to glass articles include a model predictive control framework. The methods include operating the converter, providing target values for attributes of the glass articles or glass tubes, measuring the attributes for the glass articles and glass tubes, conditioning the measurement data to remove outlier data points and calculating statistics representative of the measured attributes, and determine updated settings for one or more process parameters from the previous settings, the statistical properties, and the target values, where the updated settings are those that minimize an objective control function for the converter. The methods further include adjusting the process parameters to the updated settings. The model predictive control framework enables feedback control of the converter that compensates for disturbances that act on the process.

Methods for controlling a converter for converting glass tubes to glass articles include preparing condition sets including settings for a plurality of process parameters, operating the converter to produce glass articles, measuring attributes of the glass articles, operating the converter at each of the condition sets, associating each glass article with a condition set used to produce the glass article and the attributes measured, developing operational models from the attributes measured and the condition sets, determining run settings for each of the plurality of process parameters based on the operational models, and operating the converter with each of the process parameters set to the run settings determined from the operational models.

Disclosed is a method for manufacturing a glass article including a through hole in a wall of a glass tube. The method includes forming the through hole by heating the glass tube from above with the glass tube arranged such that a tube axis is parallel to a horizontal direction.

A method of manufacturing a tip for use with smokable substances. A tube is rotated while applying heat in a horizontal and vertical direction to an end of the tube. The heated end is squeezed with rollers and while a rotating t-shaped plug is inserted into the heated end of the tube. The rollers and t-shaped plug are removed and a scoring wheel is applied to the tube to create a scratch. Then heat is applied to the scratch. An end of the tube is clamped with a rotating chuck and water is sprayed at the scratch to create a thermal shock which separates the tube into two pieces. Heat is applied to a section of one end of the pieces. Tapered rollers are applied to the heated section to taper a diameter of the piece along the heated section.
