Wetted slab

Blanket crepes are of lower quality and are made from wet slabs obtained usually from small landholders. These are creped. dried, and baled. Other types of crepe are made from coagulum left in collection cups and from dried skin remaining from the tapping incision. In addition to collecting latex, a tapper collects all dried and coagulated rubber that remains from die previous round, usually as skin m the cup or on the tapping panel.

The concept of hthography was developed by German Aloys Senefelder in 1796. He used a stone slab with printed grease marks and dampened it with water. When a coating of ink was applied to the stone, it adhered to the grease marks and washed away from the wet areas. The ink was then transferred to paper by pressing the stone against it. 

Water-based acrylic resins offer a suitable means for injection of very fine cracks. The viscosity of such a material is very low which enables a high degree of penetration to be achieved. The resin is suitable for injection of wet cracks in walls, slabs and soffits where the crack widths are less than 0.3 mm (Edwards, 1993a). 

The techniques necessary for placing concrete depend upon the type of member to be cast, namely whether it is a column, a beam, a wall, a slab, a foundation, a mass concrete dam, or an extension of previously placed and hardened concrete. For beams, columns and walls, the forms should be well oiled after cleaning them, and the reinforcement should be compacted and thoroughly moistened to about 6" depth to avoid absorption of the moisture present in the wet concrete. Concrete should always be placed in horizontal layers which are compacted by means of high-frequency power-driven vibrators of either the immersion or external type as the case may need. It must be kept in mind, however, that over-vibration can be harmful since it could cause segregation of the aggregate and bleeding of the concrete. 

The only satisfactory manhole design is one that is monolithic. It is a waste of time and money to try to build one from block or brick. A monolithic manhole should be formed and cast, properly reinforced, of concrete in which all pours are wet to wet or the cold seams protected by a continuous water-stop and a concrete adhesive employed on each wet to dry pour. Such design requires that the bottom slab be an integral part of the structure. The next alternative is to... 

Preparation of gel slabs The glass plates are cleaned in hot detergent. Only plates that wet uniformly after this treatment are used. They are placed upright and allowed to dry. The surfaces should not be touched with the fingers. 

Compressed Gun-cotton for Torpedo Warheads and Mines. About 10 g. is removed from the centre of the printer or slab by scraping with a horn spatula. The scrapings are placed in a glass beaker of 1500 c.c. capacity, two-thirds full of distilled water, and stirred frequently for fifteen minutes. After settling, the water is poured off and replaced by the same qxtantity of water. It is again stirred for fifteen minutes, allowed to settle and decanted. The sample is collected by hand and the excess of water squeezed out. The wet gun-cotton is spread on six thicknesses of filter paper. Six other filter papers are laid on top and the sample is treated as described abow for nitrocellulose pulp.
