Rotary shell pulverizer

The pulverizer includes a rotary shell or drum which is mounted for rotation on a slightly tilted axis, and in which materials, including fertilizer chemicals and the like, are fed in a solid state to the interior of the drum for comminution. The inside curved surface of the drum is provided with a continuous array of small cups or flights for receiving deposits of larger particles of material received and which carry them to an upper portion of the drum when rotated for emptying therefrom. The drum has covers for the ends of the drum and openings in the center for receiving material at the one end and for spilling it from the other end. Particles dropped from the inclined flights on the upturning side of the drum are passed to a breaker means for pulverizing the material. Large particles that remain are collected at the bottom and are received in the inclined flights for again passing to the breaker means, and the tilt of the drum together with the length thereof provide many passes of the material through the breaker until all material spilled from the exit cover end is finely comminuted.

Device for and Method of Aligning and/or Maintaining a Side of a Spacer Frame in Alignment During Fabrication of a Multi Sheet Glazing Unit

In the manufacture of an insulating unit, a spacer frame having a pair of outer legs and a base connected to provide a U-shaped cross section has one of the pair of legs adhered to marginal edges of a major surface of a first glass sheet by a layer of a moisture-impervious sealant. An elongated side of the spacer frame adhered to the glass sheets moves out of alignment i.e. the plane containing the base of the spacer frame and the plane containing the major surface of the first sheet are not perpendicular to one another. Magnetic forces are applied to the base to maintain the elongated side of the spacer frame in alignment i.e. the plane containing the base of the spacer frame is perpendicular to the plane containing the major surface of the first glass. Thereafter, a second glass sheet is adhered to the other outer leg of the spacer frame by a layer of moisture impervious sealant. After the sheets and the spacer frame are assembled, the sheets are urged toward one another to flow the sealant to seal the space between the sheets.

In one embodiment a plurality of spaced sheet retaining members (34) is maintained on the legs (40, 42) of the spacer frame (28) between the glass sheets (24, 26). In another embodiment an inner sheet (32) has an edge mounted in an edge receiving member mounted between the legs (40, 42) of the U-shaped side of the spacer frame (28). The remaining edges of the inner sheet (32) are within the interior of the closed spacer frame (28) and spaced from the spacer frame (28) by one or more retaining members (34). In one embodiment, the sheet retaining members (34) each have a pair of flexible fingers (80, 82). A sheet (32) mounted between the fingers (80, 82) is maintained spaced from the outer sheets (24, 26). In another embodiment, the sheet retaining members each have a groove for receiving an edge of a sheet. A first part has a vertical stop and a platform.

Continuous process for oxygen-free conversion of methane

A method for dehydroaromatizing methane by contacting a feedstream that contains methane, in a circulating fluid bed reactor/regenerator, with a catalyst and under conditions sufficient to dehydroaromatize methane and produce at least one liquid aromatic compound such as benzene, toluene or naphthalene and hydrogenated products such as cyclohexane and decahydronaphthalene. The method may also be used to produce hydrogen. The feedstream may be a natural gas feedstock. The method may include one step and two step catalyst regeneration.

Low thermal conducting spacer assembly for an insulating glazing unit and method of making same

An insulating unit is disclosed having a pair of glass sheets about an edge assembly to provide a compartment between the sheets. The edge assembly has a U-shaped spacer made of metal, metal coated plastic, gas and moisture impervious polymer, or gas and moisture impervious film coated polymer. The outer legs of the spacer and the glass provide a long diffusion path to limit the diffusion of argon gas out of the compartment. The edge assembly has materials selected and sized to provide edge assembly having an RES-value of at least 75. Also disclosed is a spacer for use in insulating units including a plastic core having a gas impervious film e.g. a metal film or a halogenated polymer film. Also taught herein are techniques for making the unit and spacer. The unit has a long diffusion path to increase the time period in which insulating glass e.g. Argon gas may be retained in the compartment. The increased RES-value provides a unit that has a low thermal conducting edge. In this manner heat loss through the marginal edge of the unit is reduced.

Method of determining resistivity

Process to prepare olefins from aliphatic alcohols

A process to prepare an olefin from its corresponding alcohol is improved by reacting, under reaction conditions including a first temperature, an aliphatic alcohol and, optionally, diluent water, to form a reaction product including at least a dialkyl ether. The product is then reacted again, under higher temperature to complete the dehydration of the dialkyl ether to the desired olefin. This process is particularly suitable to prepare ethene from ethyl alcohol. The stepped temperature scheme serves to reduce the formation of byproduct aldehydes, which in turn reduces coke formation, fouling, and the need to handle large amounts of water, thereby lowering energy and capital costs.
