Floating baskets

Dead Sea, is reported. There is also reference to the use of tar as a mortar when the Tower of Babel was under construction (Genesis 11 3). Another example of the use of pitch (and slime) is given in the story of Moses (Exodus 2 3) where the basket in which he was placed to float in the river was caulked with a derivative. Perhaps the slime was a lower melting bitumen whereas the pitch was a higher melting material the one slime) acting as a flux for the other pitch). [Pg.23]

It is essential to use several small pieces from any sample of material in order to check for consistency, particularly since it may be difficult to see small bubbles attached to such a piece. It is also essential that the column be kept within a transparent constant-temperature bath, because the densities both of the liquid and of the polymer samples are highly temperature-dependent. Once the measurements have been made, the pieces of polymer or the floats are removed from the column very slowly by means of a small wire-mesh basket. This can be done without causing significant disturbance of the density gradient. [Pg.31]

Crowfoot weave It is a three-by-one weave, that is, a filling thread floats over three warp threads and then under one. This type fabric looks different on one side than the other. Fabrics with this weave are popular since they are more pliable than either the plain or basket weave. It is easier to form around curves and provide 3-D forming. [Pg.106]

Twill weave A basic weave characterized by a diagonal rib or twill line. Each end floats over at least two consecutive picks, allowing a greater number of yarns per unit area than in a plain weave, while not losing a great deal of fabric stability. This pattern has better drapability than either plain or basket weaves. [Pg.108]

Visual Observation Method Each sample of microspheres is placed into 500 ml of simulated gastric fluid (SGF, pH 1.2, without enzymes) filled in basket-type dissolution apparatus. Paddle rotation speed is set at 100 rpm, temperature is to be maintained at 37°C 0.5°C. The number of floating microspheres has to be counted visually after 24 h. The percentage of floating microspheres was calculated according to the following equation ... [Pg.1094]

There is a wide range of uses to which repo might be put. Structured transactions that are very similar to repo include total return swaps, and other structured repo trades include floating-rate repo that contains an option to switch to a fixed rate at a later date. In the equity market repo is often conducted in a basket of stocks, which might be constituent stocks in an index such as the FTSEIOO or CAC40 or user-specified bas-... [Pg.308]

For some products the USP/EP/JP rotating basket apparatus (Figure 2) may be more appropriate for example, in the case of floating capsules and granules. Operation of the basket apparatus is similar to that of the paddle apparatus, except that the basket containing the dosage form is immersed in the dissolution medium prior to starting the rotation. [Pg.3640]

The basket retrieval catheter has been used to retrieve endocardial leads. This device was initially developed for urologic use. The Dotter intravascular retriever is an example of such a device (Fig. 6.5). This system consists of a catheter with a helical loop basket and introducer sheath. With this system, the object to be retrieved becomes entangled in the helical basket. There is little or no reversibility once an object is entangled. The Dormia basket may also be nsed to retrieve free-floating remnants or loose lead ends. [Pg.272]

Polyhydroxyalkanoates (PHAs) are also biodegradable polymers. These are condensation polymers of 3-hydroxycarboxyhc acids. Thus, like PLA, they are polyesters. The most common PHA is PHB, a polymer of 3-hydroxybutyric acid it can be used for many of the things that polypropylene is now used for. Unlike polypropylene that floats, PHB sinks. PHBV, a PHA marketed under the trade name Biopol, is a copolymer of 3-hydroxybutyric acid and 3-hydrox5rvaleric acid. It is being used for such things as wastepaper baskets, toothbrush holders, and soap dispensers. PHAs are degraded by bacteria to CO2 and H2O. [Pg.1262]

There were a number of traditional aboriginal uses of jack pine (Maries et al., 2000), some of which are inner bark and needles processed to yield poultice to treat wounds and frostbite pitch chewed as a medicinal dried cones used in tanning of hides roots used to make baskets, and fish hooks made from knots. The wood was used for cabins, boat planks, fishnet floats and fiielwood. Though less effective than spruce (Picea) pitch, pine pitch could also be used for caulking. [Pg.57]
