Many of the cold packs sold in stores use this endothermic process. A cold pack usually contains a flimsy plastic bag of solid ammonium nitrate inside a larger package filled with water. When punched, the inner bag ruptures. This releases the ammonium nitrate, which dissolves and produces a chilled pack to relieve pain and swelling in aching joints. 

The prisoners of war, who were given easier jobs, remembered better and longer than most. "The inmates were forced to carry one-hundred C-weight bags of cement. It took four men to lift one bag and put it on the back of one man. When the inmates couldn t go along quickly enough to satisfy the Farben Meister, the Meister beat them with sticks and iron bars and punched them with his fists and kicked them. I have often seen them beaten to death with iron bars."... 

From a complex [5. .. 8] in a Fig. 2 the intensifier is rotined [8], in the scheme which one six hydraulic sources of efforts four from which one are counterbalanced by cradles 1 2 also concentrate an effort in building bag, and the efforts of two mutually arranged sources 7, directional from center of building bag, execute differential support of an attenuators part of punches with demanded power stroke for two-eight multiple compressions, due to what it is obviously possible to treat material gaseousness. A feature of the given intensifier is that the power stroke of a plunger 3 can make 20. .. 40 mms. 

In a Fig. 3,a the unit of building bag 3 (chamber conditionally is rotined in the increased kind and single-layer), in which one the material 4 is affected by a punch 1, bolstered by matter 2.

When spreading nonpoisonous dust, such os diatomaceous earth, punch small holes in the sides and bottom of a paper bag, place a cup of the dust inside, and shake it over the areas you want to treat. Or place the dust in an old sock, tie the end closed, and beat the sock above the plants with a stick or broom handle. Use caution, and wear protective gear to avoid inhaling dusts. 

Shape is often also important. In many cases, spherical products of size enlargement are desired. The approximate shape can be obtained with all tumble/growth agglomeration methods. On the other hand, unless extremely accurate feed control is established in some punch-and-die machines or by using wet bag isostatic pressing, spherical products cannot be produced with pressure agglomeration. The nearest approximation would be pillow-, lens-, or almond-shaped compacts.
