Ball kneading

In some factories the three ingredients are dampened with 8-10% of water and then mixed in wooden drums with wooden balls (Fig. 92). The balls work by a kneading action so that to some extent they replace mixing in an edge runner. The... 

Ten grams of aluminum powder and 40g of fine barium peroxide are mixed by shaking with 7g of powdered potassium chlorate. The mixture is kneaded with collodion into balls about one gram in weight, and a 3-inch piece of Mg ribbon is inserted. These spheres are then inserted into a small depression on the top of the reaction mixture. 

In the second approach, a thick slurry of tar sand and water is kneaded to agglomerate the oil into balls, and these are separated by mechanical means such as screening. Four similar techniques for accomplishing this are recorded in the literature, the first in England in 1921. It is interesting that two of these methods were developed outside Canada.

Add 4 to 6 tablespoons ice water, I spoonful at a time, and very briefly knead the dough until it is moist enough to hold together. Form the dough into a ball, wrap it in plastic wrap, and flatten it into a disk. Refrigerate for at least I hour. 

This is an adaptation of a chocolate plastique recipe I learned in one of my master cake-decorating classes. With an elastic texture and a taste similar to that of Tootsie Rolls, the dough rolls out thin, so it s easy to cut out shapes with cookie cutters or to make animals, robots, or any other figures, such asfowers and balls. Although the dough is easy to make, it will require a little muscle strength to knead it at first. 

Dip a toothpick in a small amount of food coloring. Insert the toothpick inside the ball of sugar paste. As you remove the toothpick, close the sugar paste around the food coloring. Knead, pull, and mash the dough to evenly distribute the color. 

Knead until smooth and elastic for 8—10 minutes. Add walnuts and shape into a ball. Place in greased bowl, turn once to cover surface. 

To strengthen the grip of your hands there ore several beneficial exercises you may use. While they are old standbys for this purpose they are, nevertheless, very effective. One consists of kneading rubber balls, the size of tennis balls or smaller, in your hands. Another is to stand with arms outstretched and crumple a sheet of newspaper up in each hand, starting by holding them only by the edge or corners and continuing until they ore balled up in your hands. This exercise does not sound impressive but a few trials will convince you of its effectiveness. 

Use your gloved hand to scoop the material out of the cup. Knead the polymer into a ball.

Hydroxylamine hydrochloride (5.00 mmol) and the aldehyde or ketone 1 (5.00 mmol) were kneading ball-milled in a double-walled 10-mL stainless steel vessel with two balls of 12 mm diameter at 20-25 Hz for 10 min at 45-50 °C (a-e) or for 30 min at 65-70 °C (f-h). A quantitative yield of the oxime hydrochloride hydrate 2 was obtained. The salt 2 already carries the catalyst for most of the various synthetic uses of the oximes. Washing with aqueous NaHC03, if required, can liberate the free oximes 3. 

Slam the clay ball onto your work surface to get rid of any air bubbles inside so that your clay will not break when it dries. Be sure to roll and knead the clay between your hands so that it becomes soft and easy to use. 

The crude product is converted to a finished pigment by means of various comminution techniques. These include ball milling in the presence or absence of a solvent, attrition by kneading, acid swelling, or add pasting. The apphcation properties of the finished product and its ultimate shade (a function of partide size and shape as well as size distribution) are determined to a large extent by the technique seled-ed.
