摘要:
A seal carving apparatus (10) includes a thermal head (12) having a plurality of heat generating elements (12a) disposed in lines, and thermal drive control means (24) that performs a control process of selectively and thermally driving the individual heat generating elements while moving the thermal head and a porous material in relative to each other with the thermal head (12) being in abutment with the porous material, thereby forming a seal face on the porous material. The thermal drive control means (24) controls a pulse time width for thermally driving the individual heat generating elements (12a) of the thermal head under PWM control based on gradation image data having a gradation value, thereby forming a seal with a gradation on the porous material.
摘要:
The invention provides a method for controlling the temperature of a container end portion during manufacture, said container being filled with a product (11), and comprising a substantially tubular body portion (10) of thin-walled plastic or laminated plastic material and a butt-weldable end-piece (13) at each end of the body portion, whereby a first end-piece is fitted to one end of the body portion and the product (11) is introduced into the container via the open end of the body portion, a second end-piece (13) is introduced into the said open body portion end to an intermediate position where it partially projects into the body portion (10), and the plastic material of the body portion end region and the second end-piece is softened through application of heat energy, characterized in that the end-piece (13), by means of relative displacement between it and the body portion (10), is pressed in to the body portion to its terminal position whilst cooling gas is supplied to the transverse wall (15) of the end-piece (13). The invention also provides an apparatus for carrying out the above method.

The invention also provides an apparatus for carrying out the above method and an end-piece suitable for use in a container thus produced.
摘要:
A method of sealing an aperture formed in a discharge tube using a laser beam. A tube (12) having the aperture (68) to be hermetically sealed is placed in a vessel (20) having a window (22) which transmits a laser beam (54). The aperture is covered with a blockade member (70). The blockade member is irradiated with the laser beam in order to melt the blockade member and seal the aperture.
摘要:
A nozzle (250) for extruding a composite material (110) from an extruder barrel (120B). The nozzle includes a body (251) and a tapered nozzle passage (252) extending through the body. The tapered nozzle passage having a nozzle inlet opening (253) configured to interface with the extruder barrel, and a nozzle outlet opening (254), where the tapered nozzle passage has a contoured nozzle passage surface (255) extending between the extruder barrel and the nozzle outlet opening with smooth transitions (270), free of angles, so that each nozzle passage surface portion (255A-255F), having a corresponding contour, transitions smoothly to each other nozzle passage surface portion, having a respective different contour, from the nozzle inlet opening to the nozzle outlet opening, and the nozzle outlet opening is defined by at least a first edge (254A) and a second edge (254A) that intersect each other at an acute angle (θ).

A resealable cap ( 110, 210 ) for a medicament vial ( 114, 214 ) has a base portion ( 112, 212 ) formed of vulcanized rubber or like material known for providing a stable environment for the medicament contained within the vial, and a resealable portion ( 126, 226 ) overlying the base portion. The resealable portion ( 126, 226 ) is made of low-density polyethylene or like material, and can be punctured by a needle or like injection member ( 140, 282 ) for dispensing medicament into the vial ( 114, 214 ). Prior to filling, the cap ( 110, 210 ) is assembled to the vial ( 114, 214 ) and the cap/vial assembly is sterilized. Then, a needle ( 140, 282 ) is inserted through the cap ( 110, 210 ) and medicament is introduced through the needle and into the vial. Upon withdrawal of the needle ( 140, 282 ), the penetrated region of the cap ( 248 ) is fused by laser ( 276 ) or direct heat sealing ( 264 ) to hermetically seal the needle hole ( 294 ) in the cap.

摘要:
The case-mould is formed by a body (1) with the shape and dimensions of the rail post we need to obtain, of plastic, obtained with the collaboration of a blasting machine, with the peculiarity that it presents a couple of lengthwise and parallel lines of incisions (3) that enable, when we want to take the rail post out, the tearing of the coat by this strip (4) defined by these lines of incisions (3), strip (4) that extends towards one extreme (5) of the case also forming a flap (6) and that makes the tearing operation easier. The invention also concerns itself about a machine that, receiving the cases coming out of the blast machine, cuts the featheredges that the cases present, the filling mouth, micro-perforations, the incisions, sealing them.
摘要:
A medical/surgical device which includes tubing (1) that is partially reinforced (16), and partially un-reinforced. The device is formed by first providing tubing which is reinforced over its entire length, severing or weakening the reinforcing element, and removing an end portion of the reinforcing element. The reinforcing element can be severed or weakened using, for example, a laser (37). Any damage caused by the severing/weakening, and/or removal of the reinforcing element can then be repaired by inserting the tubing into a heated die. An apparatus for performing the severing/weakening, removal, and repair operations is also provided.
