Ml thickener

A1 soap in which about 50% of the org adds are derived from coconut oil, 25% from naphthenic acids and 25% from oleic acid. When stirred into gasoline at a temp range from 16—29°, M1 swells until the entire vol of gasoline becomes a more or less homogeneous gel M2 Thickener. A standard (for US Air Force) incendiary oil thickener. It is an intimate mixt of 95%Ml Thickener and 5% devolatilized silica... 

Ml Thickener It is a coarse, granular material ranging in color from light tan to brown. Chemically, it is a coprecipitated A1 soap of naphthenic, oleic and palmitic acids in the approx ratio of 1 1 2. The three main disadvantages accruing from the properties of Ml thickener are (1) it is a critical wartime material since it is made from coconuts (2) it is extremely hygroscopic, and the presence of water decreases its ability to form a stable thickened fuel. In addition, the relatively large... 

M2 Thickener It is pulverized Ml thickener with an antimoisture substance (attasorb clay) added in the ratio of lp attasorb clay to 19p Ml thickener. It readily absorbs moisture from the air, but not to the extent of M1 thickener, because less air circulates thru the pulverized particles the attasorb clay further lowers moisture absorption. A container may be resealed after part of the M2 thickener has been used provided it has had minimum exposure to air. Since M2 thickener is composed mainly of Ml thickener, it retains most of the characteristics of Ml, including the disadvantages of being manufd from critical material, absorption of water from the air, and sensitivity to moisture. 

As a general comparison with Ml thickener, only two-thirds as much M2 thickener is needed to obtain thickened fuel of the same consistency (Ref 7, p 9)... 

M2 Thickener A standard (for Air Force only) incendiary oil thickener. It is an intimate mixt of Ml thickener 95 devolatilized silica aerogel 5%- M2 thickener is an improvement over Ml, not only because of free-flowing faster setting characteristics, but also because the thickener itself ge 1 formed are more stable. It is used in fire bombs [Ref TM 3-215/AFM 355-7 (Dec 1963), p 4l]... 

Structure of the Cell Wall. The iaterior stmcture of the ceU wall is shown in Figure 6. The interfiber region is the middle lamella (ML). This region, rich in lignin, is amorphous and shows no fibnUar stmcture when examined under the electron microscope. The cell wall is composed of stmcturaHy different layers or lamellae, reflecting the manner in which the cell forms. The newly formed cell contains protoplasm, from which cellulose and the other cell wall polymers are laid down to thicken the cell wall internally. Thus, there is a primary wall (P) and a secondary wall (S). The secondary wall is subdivided into three portions, the S, S2, and layers, which form sequentially toward the lumen. Viewed from the lumen, the cell wall frequendy has a bumpy appearance. This is called the warty layer and is composed of protoplasmic debris. The warty layer and exposed layer are sometimes referred to as the tertiary wad. 

M4 Thickener. A standard incendiary oil thickener. It is a diacid A soap of isooctanoic acids derived from isooctyl ale or isooctyl aldehyde obtd from the oxidn of petroleum. It contains 2% Santocel C or Attaclay SF which serves as an antiagglorherant. About 1/2 the amt of M4 and about 1/10 mixing time is reqd for M4 Thickener as compared to Ml for thickened fuels of comparable consistency. Fuels prepd with M4 are superior in flame throwing performance with respect to range, burning and target effects, as compared with fuels prepd with other thickeners...

Orally administered suspensions containing a wide class of active ingredients (e.g., antibiotics, antacids, radiopaque agents) are of major commercial importance. The solids content of an oral suspension may vary considerably. For example, antibiotic preparations may contain 125-500 mg solid drug per 5 mL or a teaspoonful dose, while a drop concentrate may provide the same amount of drug in only 1-2 mL. Antacid or radiopaque suspensions also contain relatively high amounts of suspended material for oral administration. The suspending vehicle can, for example, be a syrup, sorbitol solution, or gum-thickened water with added...

When the mixture begins to thicken, use tongs to remove the beaker from the heat. Allow the beaker to cool for 5 minutes, then place it in a cold-water bath in the 600-mL beaker. 

In the colon, semifluid material entering from the small bowel is thickened by absorption of water and salts (from about 1000 to 150 mL/d). If, due to the action of an irritant purgative, the colon empties prematurely, an enteral loss of NaCl, KCl and water will be incurred. To forestall depletion of NaCl and water, the body responds with an increased release of aldosterone (p. Ltillmann, Color Atlas of Pharmacology... 

Rabbits exposed 6 hours/day to 2 72 ppm over a 10-week period showed slight eye irritation at 997 ppm additional effects were salivation, lethargy, narcosis, mild convulsive movements, and some deaths. Lethal doses of cyclohexanol produced slight necrosis of the myocardium and damage to the lungs, liver, and kidneys. The application of 10 ml of cyclohexanol to the skin of a rabbit for 1 hour/day for 10 days induced narcosis, hypothermia, tremors, and athetoid movements necrosis, exudative ulceration, and thickening of the skin occurred in the area of contact. Ten microliters applied directly to the cornea of rabbits caused moderate to severe irritation. ...
