Abstract: The Helical segmental lining is an invention in tunneling industry wherein segments are designed in helical shape that are connected by interlocking system. The proposed helical tunnel lining method allows for segment erection and excavation to be completed concurrently and continuously by Tunnel Boring Machine (TBM) which will result in increasing the tunneling speed. The segments have tongue projection on the two trailing sides (circumferential and radial) and similar groove recess in the opposite two leading sides. This forms a tongue-and-groove joint at both circumferential and radial joints. The system allows for optional post-tensioning (PT) strand to be inserted into the leading circumferential side of the segments. The optional PT strand is fitted into a continuous groove located at the leading circumferential side of the segments.

Abstract: In the case of a drip irrigation tube the dosing elements which are inserted therein and are connected to the walling of the drip irrigation tube each comprise inlet regions, dosing regions and outlet regions, through which the water issues out of the drip irrigation tube via outlet openings installed in the tube walling. The outlet openings are in the form of a slit, the edge regions of the slit are supported by supporting means in such a manner as to limit bending of the edge regions of the slit towards the dosing elements. As a consequence, when negative pressure prevails in the tube contaminants are prevented from being able to penetrate through the slits into the dosing elements and block same.

Abstract: Tubular components for use in modular fencing systems are manufactured utilizing die-forming of a flat plastic sheet, rather than by profile extrusion of a tubular form. This approach is made feasible by an aesthetically acceptable and structurally sound longitudinal edge joint configuration.

Structural integrity is assured by staking overlapping portions of the clip members to each other at longitudinally spaced locations. This can be accomplished with a thin circular blade having teeth that rotate to pass between the peripheral side portions and to press against and deform the overlapping portions, one into the other.

Abstract: Heat exchanger with double row tubes with each tube being substantially identical and made by a sequence of roll forming operations from a single piece blank so that it has a centralized vertical connector web of the thickness of the blank connecting and supporting opposite side walls of the tubes to separate each tube into separate flow passes for augmenting tube burst strength from high internal pressures. Also, the vertical connector web effectively eliminates tube crushing from compression loads exerted onto a core of tubes and corrugated air centers by retainer bands used to hold these components together for their subsequent brazing together in a high temperature oven to form a core. With these tubes employed, heat exchanger efficiency is improved since the apices of the air centers have extensive direct contact with the flat sides of the roll formed tubes thoughout their widths.
