Abstract: The invention relates to a method for applying fluid in droplet form to a substrate, which method comprisies feeding the fluid to a nozzle so that the fluid issues from the nozzle as a single substantially coherent jet following a single jet flight path; causing the jet to break up into a series of substantially uniformly sized droplets; applying a sufficiently large electrical charge to the fluid by means of a charge electrode so as to form mutally repellant droplets having flight paths which diverge from one another, characterised in that the single jet flight path is directed into a catching means by  which the fluid is caught and prevented from being applied to the substrate, in that the jet of fluid is broken up into a stream of substantially uniformly spaced droplets and in that the divergent stream of droplets is directed away from the catching means and allowed to reach the substrate so as to deposit  fluid on the substrate.     The invention also provides apparatus for use in the method of the invention.

Abstract: Abstract of the Disclosure POLYESTER  COMPOSITION      Polyester compositions which are dispersible or soluble in water based systems can be very valuable as adhesives, coatings, paints, and the like.  The use of water based solvent systems eliminates recovery and toxicity problems normally related with many organic solvents.  The polyester compositions of this invention have an increased affinity for water based systems by the incorporation therein salts of organic sulfonic acid monomers and by carboxyl terminating these polyesters to a very substantial degree.  The water based systems in which these modified polyesters are useful contain an alcohol in addition to water.

Abstract: ABSTRACT      A data processing system having a main processing unit, a memory subsystem, and a co-processor selec-tively connectable to said memory subsystem through an Input/Output Channel Controller which includes a control means for arbitratinq access to the I/O Bus among the co-processor and the other I/O devices connected to the Bus.  Since the co-processor runs programs stored in the memory subsystem, there is a tendency for the co-processor to monopolize the bus with instruction fetch cycles, thereby excluding other I/O devices from access to the bus.  The control means for arbitrating responds to requests on the basis of a linear priority scheme in which the co-processor has the lowest priority.  Each device, except the co-processor, is permitted to keep control of the bus until it voluntarily relinquishes it.  The co-processor, on the other hand, relinquishes control of the bus in response to a request for access by any higher operator.  However, control is returned auto-matically to the co-processor in the absence of any other request, since the co-processor continually raises its access request line.

Abstract: TITLE                             QUADRUPOLE MASS SPECTROMETER                                       INVENTOR                        PETER HENRY DAWSON                              ABSTRACT OF THE DISCLOSURE This  disclosure  presents  an  alternative,  improved  approach to  the  RF only quadrupole mass spectrometers.   The ions whose masses place  them  near  the  stability  limit  for  a  given  operating  voltage and  RF  frequency,  can  be  strongly  influenced  by  the  application of a very  small  dc  voltage to the quadrupole rods.   If this voltage is modulated  at  a  low  frequency  (typically  a  few  hundred  hertz),  the (a,q)  values  will  pass  alternately  through  the  stability  boundary and ions will be transmitted with the imposed frequency.  The advantages of  the  new  approach  are  two-fold (a)  locking  amplifier  synchronous detection schemes can be used.  These give improved signal/noise ratios.          Background  noise  due  to  photons,  soft X-rays  or  escited neutrals often  a  problem  in  quadrupole mass  filters will  not  be modulated and will not be detected.  (b)  Higher resolution can be achieved.

Abstract: IMPROVING THE QUALITY OF CATALYTICALLY              PREPARED POLYALKYLENE POLYAMINES                 ABSTRACT OF THE INVENTION     Process for the improvement of the quality of polyalkylene polyamines prepared by the reaction of (1) ammonia and/or an alkyleneamine compound having at least two amino groups and an alkanolamine compound having at least one amino group in the presence of a catalytically effective amount of a metal acid phosphate and at a temperature and pressure sufficient to form the polyalkylene polyamine.  When the polyalkylene polyamines, being produced by the process, have a dark black color which is measured as a Gardner Color Standard Number of at least 15 on the Gardner Color Scale and/or have a burnt or scorched odor, the inclusion of a sufficient amount of hydrogen with the ammonia and/or alkyleneamine compound and the alkanolamine compound, so that the hydrogen is in contact with the ammonia and/or alkyleneamine and alkanolamine in the reaction zone, will abate the burnt or scorched odor of the polyalkylene polyamines being produced and will lower the Gardner Color Standard Number of the polyalkylene polyamines being produced to 10 or below on the Gardner Color Scale.  The best results are obtained by introducing the hydrogen along with the reactants into the reactor.  By always using the hydrogen addition, one can abate or eliminate the poor quality problem from arising by thereby avoiding the production of such black, malodoriferous polyalkylene polyamines.

Abstract: ABSTRACT            A lineman's safety strap assembly is intended for attachment to a body belt.  An elongated strap terminating in a buckle at one end for varying the length of the safety strap is provided with a first hook for coupling the safety strap to the body at the other end.  A second hook for coupling the safety strap to the body belt is slidably mounted on the safety strap.  An inclined sharp edged roller is slidably mounted on the safety strap for movement toward the midpoint of the strap.  A cross belt terminating in spring-backed latches at both ends may be slidably coupled to the safety strap at two locations in order to form a closed loop for encircling the pole with the rollers facing inwardly.  In the event of a fall, the cross belt bears against the inner face of the pole and the safety strap jams in the latches, while the lower edge of the roller is pulled into biting engagement with the outer face of the pole.  The lower edges of the latches may also dig into the face of the pole.  The assembly thus provides a braking feature in the event of a fall, but the configuration of the roller is such that it does not hinder the lineman in ascending or descending a wooden utility pole when the braking feature is not needed.
