Clothes pins

Wrap stripped ends of leg wires around clothes pin jsws to make ele -trical contact. 

Asserriblc charge, adapter, electric blasting cap, and clothes pin. 

Attach shipped ends of circuit wires to ends of clothes pin to farm contacts. Attach taut trip wires below contacts. 

Attach stripped ends of circuit wires to clothes pin to tnaice contacts. 

When you are happy with your design, glue the sides of the boxes together with the glue. Hold them together with the clothes pins. Let dry completely. 

With the shear-type coupling, the elastomeric element may be clamped or bonded in place, or fitted securely to the hubs. The compression-type couplings may be fitted with projecting pins, bolts, or lugs to connect the components. Polyurethane, rubber, neoprene, or cloth and fiber materials are used in the manufacture of these elements. 

Among the first dermal dosimeters used in exposure research were 4 x 4-in cellulose or gauze patches which were pinned to the outer and inner surfaces of clothing or vests which farm workers would wear during the application or re-entry phase of the smdy. These patches were easy to manufacture and when pinned to the shirt or pants of the worker made for an easily used dosimeter pad. The major advantage to the use of the patch to estimate worker exposure was this method s ability to differentiate the relative contributions of pesticide residues to different parts of the worker s body. This sampling technique in turn could lead to recommendations (i.e., the use of... 

The dermal exposure patches were made of 9-ply gauze (2,4,5-T study) or denim (2,4-D study) and were attached with safety pins to workers clothing by research team members wearing clean gloves. Following the spray activities, the patches were placed in individual specimen bottles and transported to the laboratory for analysis. In the 2,4,5-T study, all six patches from each individual were pooled before analyses were made in the 2,4-D studies the patches were kept separate and analyzed individually. Using a photograph of the worker in his spray attire and the amounts of pesticide found on the patches, we estimated total dermal exposure for each worker (Durham and Wolfe, 1962). 

The zipper was not invented until 1891 by a man named Whitcomb ludson until then, people used buttons, hooks, and pins to keep their clothing together. 

Porcupine quills have been used as sewing pins and needles, as fasteners for cloth and leather, and as decoration. Quills readily accept dye, and have been used to create rich patterns on clothing and personal items. 

The drag sled snrface sampler (Fignre 3.5) is a simple device constructed of a 7.6-cm X 7.6-cm x 1.9-cm thick block of wood or other material, which is used to hold down a 10-cm x 10-cm piece of denim cloth sampling medium as it is dragged across the floor. The bottom of the block is covered with solveut-riused aluminum foil and the denim patch is placed over the foil. Staples or push-pins are typically used to secure the sampling medium to the block. A 3.6kg weight is centered on top of the block to provide a downward pressure of 4500 Pa. The... 

The only unique aspect of this type of ceramic work is the addition of chopped strands or small strips of fiberglass cloth to the wet clay body. This can be done with a rolling pin for flat or "slab"... 

If a thinner membrane is required, then one must choose a supported membrane. The permselective metal layer may be palladium or, more commonly, palladium-silver alloy, palladium-copper alloy, or other alloy of palladium. The permselective layer ranges in thickness from about 2-25 /an thinner than 2/rm is very difficult to achieve without introducing pin holes and other adverse defects into the permselective layer. The support layer is porous and is composed of either metal (such as sintered stainless steel or tightly woven wire cloth) or an inert ceramic alumina is very common. Since all of the mechanical strength is derived from the support layer, consideration must be given to its shape and thickness. 

Starch and Other Flours Grinding of starch is not particularly difficult, but precautions must be taken against explosions starches must not come in contact with hot surfaces, sparks, or flame when suspended in air. See Operational Considerations Safety for safety precautions. When a product of medium fineness is required, a hammer mill of the screen type is employed. Potato, tapioca, banana, and similar flours are handled in this manner. For finer products a high-speed impact mill such as the Entoleter pin mill is used in closed circuit with bolting cloth, an internal air classifier, or vibrating screens. 

Put the cabbage in a stainless steel bowl with 1 tablespoon of salt and pound well until some of the juices start to flow. The flat end of a wooden rolling pin is excellent for this job. Loosely cover with a cloth and leave for 24 hours.
