When filling cracks in separate sub-portions 2 of a structure 1 by surrounding each sub- portion with a closely fitting fluid-impermeable covering 3, sealing boundary edges of the covering to the structure to form a fluid-tight enclosure 41 and evacuating the enclosure to draw hardenable ...
In recent years there has been an increased use of flexible containers as an alternative to large metal cans for packaging food products, such as juices, sauces, purees, fruits and vegetables, for institutional and commercial use. These flexible containers are often formed with walls intended to ...
1. Clean the dirt in the gap of the tile first. The depth of the gap is more suitable for 2-3 mm. It is recommended that the gap be too large and then use tile reform. 2.Tile the tile reform upside down and shake for about 20 seconds, tear off the sealed aluminum foil, unscrew...
With the use of prefabricated post systems, drills are often used to remove root dentine to create a post space. This reduced residual dentine thickness may result in the formation or propagation of microcracks [45,46]. Moreover, actively screwed post systems may also produce dentinal cracks a...
(e.g. gaps and cracks) to prevent the build-up of micro-organisms and biofilms. We also focus on eliminating exposed screw threads, metal-to-metal joints of fasteners, gaps in hinges. In addition, all machine components in contact with the product are made of AISI 316L grade stainless ...
It follows from the figure that, in the last 3-4 mm from the apex, voids were present mainly in the roots filled with the Th compaction method; i-voids occurred on the entire surface of contact with the walls of the root canal obturation and s-voids mostly in the coronal part of the...
Neither corner cracks nor barrel cracks were observed as shown in Figure 19. The thermal integrity was excellent for all through hole sizes plated. Surface Appearance and Structure Under the plating condition shown in Table 1, MacuSpec VF-HT 200 p...
The resulting paste is placed in 3 conical cracks, drilled into the dog's canine teeth, and it hardens immediately when using a light-emitting lamp. After 26 months the seal remains in the tooth and there is no noticeable mechanical decrease or weakening in the crack. ...
Comparative A exhibits large cracks that result from the thermal cycling. Example 2, however, shows no sign of cracking after the thermal cycling. The better performance of Example 2 is attributed to the presence of the mesh tube.<- Previous Patent (Pad formation method...) | Next Patent (...
In some procedures, the colloid is applied into the canal spaces30without pressure and without binding the injection needle50to the walls of the canal space30, which advantageously may reduce application of pressure to the liquid42present in the canal space30and may allow the liquid42to be ...
