Stitched joint

A variety of stitch types can be disassembled using this technology. Stitched joints snch as 301 lockstitch require the microwave-triggered thread to be present only in one section of the stitch stfucture. This means only the upper bobbin thread or upper needle thread needs to be made from the miCTowave-triggered thread to enable disassembly (Figure 7.3). 

Shipping cartons for hquids in cans and bottles, bulk solids in jars, pouches, and folding boxes, and briquetted items with or without individual packaging are usually made or corrugated kraft paper. The most common styles are the regular slotted caiton (RSC), the end-opening RSC, and the center special-full overlap slotted container (SFF). End joints may be stapled, stitched, glued, or taped.

All joints, including deck plate to structural members, shall be continuously seal-welded to prevent crevice corrosion. Stitch welding, top or bottom, is unacceptable. 

Stitching - A method of joining two pieces of uncured rubber compound together by means of a stitching roller, and a hand held tool comprised of a wheel with a narrow edge which is often serrated. It is commonly used to make tank lining joints. 

Green veneer can be edge-stitched/sewn using either a zig-zag or looper stitch. A polyester thread is usually used as it shrinks by about the same amount as the veneer when dried. The jointed veneer is fed into a programmable clipper and onto an automatic stacker.

Alternatively, bonded steel or fibre reinforced rods can be inserted from the sides of members in the joint area, in the direction perpendicular to the grain, thus stitching the timber fibres together and avoiding splitting (Fig. 9). Whenever possible, long rods should be driven all the way across the timber member width, or shorter ones should be driven from both sides.

A graduate student was using a rotary evaporator to remove solvent from a product. The student attempted to disconnect the round bottom flask from the ground glass joint of the vapor tube of the rotary evaporator but found it was stuck. As pressure and torque was applied the tube broke off just above the male fitting of the vapor tube. The sharp edges remaining on the rotary evaporator apparatus, cut the back of the hand above the thumb and several stitches were required to treat the wound. 

The aerospace industry generated a range of structures with shapes and construction details that could not be compromised to help analysts. These forms were beyond classical solutions. Approximate methods had to be relied on. The development of these techniques was piecemeal, a stitching together of several different discourses. If the monster that resulted still shows its joints, it nevertheless asserts its universal applicability and threatens the destruction of all alternatives. Modern structural analysis bears the traces of at least three conceptual bases. 

Stitching consists in the removal of cracked masonry units along the crack and replacement with new sound masonry units laid in mortar of adequate composition (Fig. 2). If necessary, some of the bed joints along the crack may be locally reinforced. To this purpose, steel plates are inserted in the mortar joints (Fig. 2). The plates are smooth and, hence, of limited bond with the mortar. It is therefore advisable to artificially roughen them. 

It should be noted that (a) the separation between the walls is not reversible and (b) the steel plates inserted into mortar joints are passive (i.e., they are mobilized in case further relative displacement of the walls takes place). Therefore, the cracks - after stitching - have to be grouted.

Old joints should be scraped clean and wiped with degreasing solvent new joints should be of scarf form made with a clean sharp knife. Belt drive joints should be stitched if an impact adhesive is used, otherwise the joint will creep under sustained high loading. A reactive adhesive that is flexible when cured is the most satisfactory for this purpose.
