Abstract: ABSTRACT This invention relates to a method of converting certain aluminas to purer more desirable forms of alumina.  More particularly it relates to a method of upgrading the alumina by-product of the Ziegler higher alcohol process.  The novel process of this invention for treating a charge alpha alumina monohydrate characterized by high purity, by substantial absence of alkali metal ions, and by presence of titanium as a principal impurity, includes the steps of:  (i) calcining said charge alpha alumina monohydrate at temperature of about 800°F-900°F for 1-3 hours thereby forming a calcined charge alumina containing gamma alumina;  (ii) mixing said calcined charge alumina containing gamma alumina with about 2-10 times its weight of water thereby forming a wetted alumina; and (iii) heating said wetted alumina at pH of about 6-12.5 to about 190°F-250°F for 8-24 hours thereby forming a heated alumina containing beta alumina trihydrate.

Also disclosed is a dual feed extrusion head for manufacturing such hose in which an outer nozzle assembly include two annular plates bolted together and separable for easy cleaning.  Such outer nozzle assembly is adjustably mounted on the forward end of the extruder head frame.  A tubular inner nozzle assembly is provided with a nozzle assembly and spaced therefrom,  A fabric guide is positioned around the inner nozzle assembly and establishes the spiral configuration of the reinforcing fabric which in turn feeds in between the inner and outer nozzles.  The inner nozzle is axially adjustable with respect to the outer nozzle.  The extrusion head is constructed so that substantial access is clearance is provided around the inner nozzle assemble to provide an open feed path for the fabric as it approaches the fabric guide.  A central pin which is axially adjustable within the inner nozzle assembly constitutes part of the nozzle and also provides means to expand the inner layer to extend the fabric and insure good bonding contact between the two layers of the hose.

Abstract: ABSTRACT      As synthesized by conventional technique, zeiolite ZSM-5 is crystallized in the presence of substantial amount of tetraalkylammonium cations, the alkyl groups of which contain 2 to 5 carbon atoms, such as, for example, tetra-propylammonium.  When synthesized in the conventional way, ZSM-5 contains tetraalkylammonium cations as well as substantial amount of sodium ions.  To obtain a more catalytically active form of ZSM-5, the sodium ions must be exchanged to very low levels.  By synthesizing zeolite ZSM-5 according to the present method, i.e. in the presence of one or more diamines and with a specifically defined reaction mixture composition, ZSM-5 having different organic nitrogen-containing cations but the same crystal structure as conventionally prepared ZSM-5 is obtained.  The ZSM-5 prepared in accordance hereto is very low in sodium content as synthesized.

Abstract: ABSTRACT    Alphabetic labelling of articles includes the use of a label having on a portion of it's face a first set of indicia and on another portion of it's face a second set of indicia which relate to the same subject matter as the first set.  The second set of indicia is oriented in reverse and upside down relative to the first set.  A machine readable code unique to the subject matter of the sets of indicia is located on one of the face portions of the label.  The label when folded about it's length isolates the two fields and on application to an article, provides visual identification of the article from two of it's sides.  The label may be provided with a machine readable indicia code which is representative of at least one indicium of either of the sets.  An article labelling system may be adapted to read the indicia code and apply as controlled by the reading operation, one or more labels having letters corresponding to the coded indicia.  alphabetic labelling of articles by use of this special printed label may be done auto-matically by the system or the label may be applied manually.

Abstract: ABSTRACT This invention relates generally to irrigation sprinklers of the impact or reaction drive types, and, more particularly, to a method and device for enhancing water distribution from such sprinklers when operated at low pressures.  Large amounts of energy are required to maintain the supply pressure necessary in prior art sprinklers to produce the desirable small droplets. The cost of the energy consumed by high capacity supply pumps, in addition to the booster pumps often required, significantly increases the cost of operating such sprinkler systems.  The present invention enhances the distribution of water from an impact or reaction drive sprinkler by use of a nozzle which separates the flow of water through the sprinkler into two distinct and separ-ate streams.  The nozzle then directs the separate streams such that they intersect at a point downstream of the nozzle to break the stream into small droplets, even when the water is supplied to the sprinkler at relatively low pressures.

The speed signal is compared with a reference signal in a comparator. The signal output of the comparator is connected to a signal input of an electrical actuation device for driving the impact member, the actuation. of the drive being terminated only after a stop signal has appeared on the signal output of the comparator. The speed-find-position-signal determines the amplitude of the actuation current pulse in order to achieve a constant impact force (constant speed of the impact member) and a constant flying time, although position and speed of the impact member at the successive moments of starting actuation may differ.

Abstract: ABSTRACT OF THE DISCLOSURE         Improved process for vapor phase cracking of dicyclopentadiene and synthesis of 2,3-dihydrodicyclopenta-diene therefrom.  Initially, a feedstock consisting essen-tially of dicyclopentadiene and cyclopentene is subjected to thermocracking in the vapor phase, resulting in the conversion of dicyclopentadiene to monomeric cyclopenta-diene.  The presence of cyclopentene in the feed stock is believed to minimize coke formation on the interior walls of the cracking chamber.  Subsequent selective catalytic hydrogenation of the resulting mixture converts sub-stantially all of the monomeric cyclopentadiene to cyclo-pentene.  The cyclopentene, prepared in the above manner, can be combined with additional quantities of dicyclo-pentadiene and the resultant mixture subjected to dimeri-zation in the liquid phase at elevated temperatures, thereby forming the monomer, 2, 3-dihydrodicyclopentadiene.
