DEF

An annular opening for introducing melt into a mold, used to make cylindrical parts.

CONT

In gating into hollow tubes, flow considerations can dictate an even injection flow pattern. A single gate is not sufficient. Four gates 90° from each other produce four flow lines down the side of the piece, which may be objectionable. To overcome this, a diaphragm gate is used. The inside of the hole is filled with plastic directly from the sprue and acts as a gate. It must be machined out later. A ring gate accomplishes the same thing from the outside.

Record 7 2011-05-31

English

Subject field(s)
  • Analytical Chemistry
OBS

Two main types of sample splitter are in common use, known as calibrated lead devices, and dividing valves. Most of these are based upon the principle that the head of the capillary column constitutes only a small proportion of the total outlet from the sample injection block. As the carrier gas enters the block it carries a small amount of the sample into the capillary column while the remainder is vented away through a larger opening. This can be done by having the capillary column held at the axis of a circular hole in the injection block, or by having it forming a narrow arm of a T-or Y-piece at the column head. In either case the amount going into the capillary column can often be further regulated by means of a tapered needle control.

English

Subject field(s)
  • Atomic Physics
  • Semiconductors (Electronics)
CONT

Electron trap generation in the gate oxide is a major reliability problem, since it can cause stress-induced leakage current and oxide breakdown. In this paper, traps are created either by the substrate hole injection or the Fowler-Nordheim injection. The attention is focused on how detrapping affects the generated traps. The detrapping is achieved by different techniques, including electron-hole recombination, and field or thermally assisted tunnelling.

GP 2000 Grout Pump. Description: The MBT GP2000 is a spiral (Rotor/Stator) pump used for mixing and pumping of cementitious grouts and the spraying of repair mortars and small volumes of shotcrete. It will deliver approximately 2m’ per hour of any pumpable material with an aggregate size up to 4mm. The stator has an adjustable clamp housing which maintains a constant output pressure and lengthens the service life of the pump parts. Recommended for: placement of grouts for encapsulating cables and rock anchors - particularly in mining applications, spraying of repair mortars, spraying of shotcrete.

OBS

In general terms, grouting refers to the injection of a suitable binding admixture into the ground as a means to fill voids, consolidate loose formations, stabilize structures, or as an isolating barrier. It can be classified under three main areas in construction applications. a. Cement grouting : A combination of mixtures such as cement/sand/bentonite is used to fill voids and can consolidate coarse soils, sands, gravels and the like. Usually pumped into a drilled bore hole under low to medium pressure or by the tube-et-manchette method. b. Chemical grouting... c. Fissure/Permeation grouting...
