Abstract: GLYCOSIDIC SURFACTANTS ABSTRACT OF THE INVENTION The present invention provides a simplified process for preparing surface active glycoside mixtures such as the C8-C22 alkyl glycosides directly from hydrophilic saccharide-containing compositions by fatty alcohol interchange. The lipophilic fatty alcohol and hydrophilic saccharide-containing compositions are rendered reactively compatible with one another by incorporating into the reaction medium a sufficient amount of nonionic surface active agent (e.g. long-chain organo glycoside) to permit the fatty alcohol interchange. As illustrated by the examples, long-chain alkyl glycoside mixtures can be easily prepared under acid catalysis and elevated temperatures for either dextrose or lower alkyl glycoside mixtures by direct fatty alkyl alcohol interchange by means of reaction medium which contains a sufficient amount of long chain alkyl glycoside to render these normally incompatible reactants reactively compatible with one another. Relatively small amounts of nonionic surface active reagents (e.g. 0.2 moles for each mole of anhydrous glucose unit) have been found to significantly increase fatty glycoside mixture yields under the processing conditions of this invention.

Abstract: ABSTRACT         A reusable industrial drum is formed by temporarily joining the periphery of the end closure to the rim of the cylindrical shell by curling to produce a spiral seam.  The outermost layer of the seam, consisting of a portion of the end closure, is cut to permit the end closure element and shell to be separated and disassembled.  Further processing operations may take place on the closure element and shell separately.  The closure element is thereafter re-mated with the shell, a seam sealant having previously been introduced between the parts, and a locking ring such as a bolt or chime ring is placed over the reassembled seam.  The locking ring surrounds the periphery of the seam to hold the seam together.  After use, the drum can be readily disassembled for reprocessing and reuse by simply re-moving the bolt or chime ring.

Abstract: DUAL CATHODE BEAM MODE FLUORESCENT LAMP                ABSTRACT OF THE INVENTION      The lamp shown herein is a beam mode fluorescent lamp for general lighting applications.  The lamp com-prises a light transmitting envelope, having a phosphor coating on its inner surface, enclosing a pair of therm-ionic electrodes and a fill material, such as mercury, which emits ultraviolet radiation upon excitation.  During application of the first polarity of an AC signal, one electrode acts as a cathode and the other electrode functions as an anode.  During the other AC polarity, the electrodes reverse their functions.  This invention re-duces the requirement for input power to a beam mode dis-charge lamp without adversely affecting luminous output. This lamp substantially eliminates wasted electron bom-bardment energy to the anode by use of this energy to help heat the cathode for the next half of the AC cycle. This lamp employs a single power source and may be used in various pre-heat or rapid start configurations.

Abstract: "PREPACKED WELL SCREEN AND CASING ASSEMBLY"      ABSTRACT           Prepacked well screen and casing assembly for use in wells provides very substantial savings in the expense and time required to complete a well as compared to the conventional techniques of down-hole perforating and gravel packing.  The assembly includes an external cas-ing or liner member which would be provided with a large number of per-forations during manufacture.  A pipe base screen jacket assembly is positioned concentrically within the casing and attached to it by readily machinable upper and lower annular ring members.  The hollow cylindrical annulus between the screen and casing is filled with a resin-coated gravel pack material which is cured after the fill opera-tion to maintain its integrity.  The assembly can be hung in the un-cased producing zone of a new well by a liner hanger or could be placed in an existing cased well which is to be reworked by first mill-ing away the existing casing in the production zone.  If reworking of the well should ever be required, a washover tool can be used to re-move the annular ring members so that the screen jacket assembly could be replaced or repacked by conventional techniques.

Abstract: ABSTRACT A joint and male and female tubular element are disclosed where the threads of the female and male members have negative load flanks and have two or more radial steps axially separated one from another by a reverse angle torque shoulder having one or two adjacent conical sealing surfaces. The reverse angle torque shoulder produces radial positional interference of the conical sealing surfaces when the male and female members are fully assembled and serves as a pos-itive assembly stop.  The negative load flank angle of the threads and the reverse torque shoulder angle combine to interlock the male and female members and to prevent dif-ferential radial separation of the conical sealing surfaces when the joint is exposed to internal pressure, external pressure or both.  Tapered threads and sealing surfaces and interference threads may advantageously be used in joint construction.          Tapered conical sealing surfaces are provided in a preferred embodiment where the taper of the member having the thinner wall thickness at the seal surface is inclined at a smaller angle with respect to the axis of the threaded connection than the complementary conical seal surface of the mating member, may advantageously be used to that the bearing load across the entire axial width of the male and female sealing surfaces has a relatively even distribution at final make-up.

Abstract: ABSTRACT OF THE DISCLOSURE Restoration of  a  gas-inslulated  type  circuit breaker  having  a  puffer  assembly  to  "contact-closed" condition is achieved in a positive and reliable manner by providing the puffer cylinder with one or more apertures that relieve the back-pressure created by the rapid expan-sion  of  the puffer chamber during the  contact-closing stroke  of  the  arc-interrupter  unit.   The  pressure-relieving aperture or apertures are so shaped and located that they are  automatically opened  and  closed  at  the proper times by the movement of the puffer cylinder and movable contact relative to the stationary piston compon-ent.  The gas-compression and puffer functions during the contact-opening operation and  subsequent  relief of  the back-pressure condition during the contact-closing opera-tion of the circuit breaker are thus provided without the need of check valves heretofore employed in the piston head to control the flow of the insulating gas into and out of the puffer chamber when the breaker is actuated through a full cycle of operations.
