Abstract: MAN-MADE ANTISTATIC TEXTILE FILAMENT      ABSTRACT A novel biconstituent filament, such as multifilament or monofilament yarn or staple fiber, useful for dissipating static electricity from normally static prone textile articles comprising a first constituent substantially adhered legthwise to a second constituent is provided.  The first constituent is made of a synthetic thermoplastic fiber-forming polymer that is virtually non-conductive to electricity.  The second constituent is a normally non-conductive synthetic thermoplastic fiber-forming polymer rendered electrically conductive by having dispersed uniformly throughout a sufficient quantity of electrically con-ductive carbon black to provide an electrical resistance of less than 1 x 101° ohms per centimeter for the biconstituent filament at a direct current potential of 0.1 volt as measured at 20% relative humidity and 21°C.  The cross sectional area of the second constituent comprises from about 1 to 30 percent of the cross sectional area of the whole filament.  The first constituent partially encapsulates the second constituent in an amount of at least 50 percent.  The interface between the two constituents is curvate in shape and extends from one side to the other of the filament.  Textile articles containing only a small amount of such filaments are rendered antistatic and retain such property even after prolonged use.

Abstract: Abstract of the Disclosure A method is described for the direct preparation of N-acyl, e.g. acetyl or benzoyl, derivatives of alpha-amino-gamma-keto acids, which are new compounds.  The method comprises adduct formation between a primary amide and glyoxylic acid or esters thereof and the subsequent reaction of the said adduct with 1, 3 dicarbonyl compounds in the presence of an acid catalyst.  Examples of 1, 3 dicarbonyl compounds are 1, 3 diketones and beta-keto esters or methylene substituted compounds thereof.  The N-acyl derivatives of alpha-amino-gamma-keto acids can be transformed directly into new compounds of nitrogen heterocyclic derivatives, which are interesting inter-mediate active compounds in the pharmacology industry.

Abstract: ABSTRACT OF THE DISCLOSURE   Holes in railway ties are drilled and impregnated with creosote or other preservative using a hollow drill with consecutive drilling and creosote injection cycles, either at the time of rail mounting or in a prior processing stage so as to produce a tie with improved resistance to deterioration, for example due to ingress of water in the tie hole,  The invention enables the preservation of pretreated ties, which are subsequently drilled to receive spikes for rail tie plates, by continuing the skin of creosote or other preservative from the outer surface of the tie to the walls of the drilled hole.  A sealing collar assembly is mounted on the drill to prevent egress of preservative from the hole during the injection process.

Abstract: ABSTRACT OF THE DISCLOSURE           A pavement marker for providing a marking signal on the roadway surface capable of reflecting light impinging thereon and for reflecting light back toward the source thereof so as to be visible to a driver in an oncoming vehicle, comprises a base hav-ing a generally horizontal bottom surface and at least one wall positioned in use in the direction of an oncoming vehicle.  A lens member of light-transmitting synthetic resin is carried by the base and has a front face oriented so as to make an acute angle of between about 15° and about 60° with the base to rise above the roadway surface upon which the pavement marker is to be installed.      The base includes means cooperating with the rear surface of the lens member for providing a plurality of hermetically sealed cells, the lens member including a plurality of retro-directive cube-corner-type reflector elements in the portions thereof occupied by the cells, the reflector elements being oriented to reflect light impinging upon the front face of the lens member in the areas corresponding to the cells back toward the source thereof to render the reflector structure highly visible at night.  Abrasion-limiting means in the form of a thin glass sheet overlies the front face of the lens member in the areas occupied by the re-flector elements, the glass sheet reducing the degradation of optical efficiency normally caused by abrasive tire contact on the lens member while allowing adequate cleaning by tire wiping action so that optical efficiency of the pavement marker is en-hanced.  In a second embodiment, spaced, abrasion-limiting ridges parallel to the direction of traffic are carried by a portion of the front face of the lens member and raised thereabove for form-ing a plurality of channels, the ridges absorbing substantially the full impact forces and abrasive contacts of tires for minimiz-ing abrasion of the other portions of the lens member while adequate cleaning of the lens member is obtained by the action of tires, including a combination of high velocity air and rainwater being forced through the channels by passing tires.

Abstract: IMPROVED FILM PROCESSING APPARATUS            Abstract of the Disclosure Processing apparatus for developing exposed film by sequentially subjecting an emulsion side of the film to processing liquids.  The processor has an elongate, horizontally disposed tank divided into a plurality of serially arranged compartments for holding the liquid. The film emulsion side faces downwardly and passes over a nozzle plate disposed between the film and a drainage opening for each compartment which forms a processing liquid curtain that contacts every part of the film's emulsion side.  A cover plate on top of the film guides the film and includes longitudinally extending pressure-relieving grooves to prevent the film from adhering to the plate.  The drainage opening for each compartment is slanted and a processing fluid return line guides the fluid from the compartment to a collection point for recirculation.  The return conduit has a sufficiently large diameter so that the returning liquid does not fill the complete cross-section of the conduit.  A spirally wound member is disposed in the conduit and liquid flowing from the drainage opening to the collection point flows at a relatively low speed along the spirally wound member.  The apparatus also includes film drive rollers positioned between adjacent compartments which advance the film and simultaneously remove therefrom processing fluid before the film enters the next compart-ment.
