There is disclosed a thermosetting phenolic resin composition, suitable for use in injection molding, which resin composition contains a molding grade phenolic resin and an effective amount of a reactive compound (e.g., para-t-butylphenol) that is capable of reducing the viscosity of molding compositions containing said phenolic resin composition to a processable viscosity at a temperature at whic...

Apparatus and method for cleaning dirty gases using an apparatus comprising a particulate bed through which the dirty gases pass upwardly without being fluidized while a wash liquid descends through the bed .Clean gas supplied to a small region below the bed passes through a channel within the bed. Bed particles, preferably hollow spheres of polypropylene, are entrained in the clean gas and are tr...

Improved apparatus intended to allow the operations of washing of suspended solid materials in a liquid phase for removing therefrom solubilized materials and/or effecting accurate granulometric separations of solid materials suspended within said phase, said apparatus comprising a vertical column wherein are arranged horizontal perforated plates (15), means for the supply of the suspension to be ...

In the method for biochemically digesting organic substances, particularly for the treatment of waste waters, residual waters, respectively settling slurries, are supplied to a digestion stage in an aerobic processing step and on the other end to a putrefaction stage in an anaerobic processing step. In order to obtain an efficient biological treatment, respectively a thorough purification of resid...

A reagent storage and delivery apparatus. The invention includes containers (11, 12, 13) with elastomeric septums (16) in the mouth portions (15) thereof. When attached to a supporting rack (19), a hollow needle (24) on the supporting rack (19) pierces the elastomeric septums (15) and allows the reagent to be dispensed from the containers (11, 12, 13) through the needle (24).

A key cutting device (20), for replacement keys, having a key blank support member (30), a lever-actuated shearing punch (25) for the key blank, and a depth-gauging stop (33) for the support member (30); the shearing punch (25) is formed to provide an optional two-step (44, 46) cut on the key with a control stop (49) for limiting the stroke of the punch to one step or two steps, as desired, for cr...

A process employing bodies that are fabricated to have a specific configuration are useful for the storage of information such as digital data. In one embodiment a material, such as germanium, is etched to produce a structure having a multiplicity of columnar or conical features. By providing a sufficient number of these features per unit area, it is possible to store at a relatively high density ...

An improved moisture and dust seal assembly is disclosed which is especially suited for application in small hand-held radio apparatus or the like which includes a molded plastic enclosure. A vertical wall is provided on one of the mating members forming the enclosure, such as the cover. The wall has essentially right angle corners and is adapted to receive a standard O-ring thereabout. The assemb...
