Abstract: Abstract of the Disclosure A nitrogen injector system is provided including a nitrogen injector unit.  The nitrogen injector unit includes liquid nitrogen with a head space having gaseous nitrogen at a pressure exceeding atmospheric pressure.  An injector orifice is provided, as is a distributing disk which normally closes that orifice.  The distributing disk is provided with metering apertures for receiving metered amounts of liquid nitrogen from a nitrogen receptacle and transporting those metered amounts to a position adjacent the injector orifice and for opening the orifice when the metered amount is in the requisite position.  The pressure of nitrogen gas within the head space is utilized to eject the metered amount from the metering aperture into a container located at the dispensing position.          Containers are advanced to the dispensing position on a con-tainer conveyor.         The distributing disk is rotated at a speed propor-tional to the speed of the container conveyor with a common drive such that a requisite amount of nitrogen will be dispensed to each container regardless of fluctuations in the speed of the conveyor.         A solenoid is provided for selectively disabling the ejection of liquid nitrogen by the disconnection of a gas discharge conduit which couples the injector orifice with the high pressure nitrogen gas within the head space.

Abstract: ABSTRACT    An apparatus is disclosed for regenerating a filter trap used to collect particulates from the exhaust gas of an internal combustion engine.  The apparatus comprises: (a) means providing a flow of a heat transfer medium through the filter trap; (b) means for heating the heat transfer medium to a temperature effective to incin erate the particulates in the filter trap; and (c) a flow mask stationed in the flow of heat transfer medium, upstream from said filter trap, effective to divert the heat transfer medium away from the radially inner zone of the filter trap while guiding the heat transfer medium to engage and ignite the particulates along a radially outer region of the filter trap.  The mask is a circular disc and spaced upstream from the filter trap efective to mask a central core area of the flow of heat transfer medium.        The means for heating comprises one or more electrically heated resistance elements arranged in a planar coil conrfiguration extending transversely across the flow of heat transfer medium.  A flow diffuser is stationed upstream from the mask and is comprised of a plurality of foraminous plates effective to diffuse and slow down the flow of heat transfer medium for increasing heat exchange.  The flow diffuser has a radiation reflec-tive coating to limit heat losses and a member is em-ployed for depressing the temperature required to ignite the particulates.

Abstract: ABSTRACT OF THE DISCLOSURE An electric arc heater having outlet gas admis-sion.  The mounting flange of an electric arc heater has a channel extending about its circumference which  is  en-closed by a detachably fastened plate to form a manifold. A passageway for the material to be admitted is provided between an outer surface of the mounting flange and the manifold.  A plurality of peripherally spaced passageways are provided in the plate intermediate the manifold and the flow path of the arc heated gas exiting the arc heater outlet providing for the uniform distribution of the added material into the arc heated gas.  By varying the position of  these passageways  a broad  range  of admission paths ranging from substantially parallel to the flow path of the arc heated gas to substantially perpendicular can be achieved without the use of additional downstream admis-sion collars and seals.  An annular gap can be provided between the plate and flange intermediate the peripherally spaced passageways and the flow path of the arc heated gas, the gap width controlling the flow rate of the mate-rial being added, preferably at sonic velocity.

Abstract: A B S T R A C T            This invention relates to sequential blasting utilising electronic circuitry to steer detonating pulses to suc-cessive detonators.  Modules are provided which contain a two-terminal element that has the characteristic that in its first normal state it has a high resistance in at least one direction and it may be changed into a second state in which it has a low resistance in both direc-tions by a suitable pulse.  Further, a detonating signal does not flow from one power line to the other through the particular module that is being addressed, but from one side of one module through a connecting link and then through the other module.  Thus, each module has an input steering terminal and an output steering terminal, with the output steering terminal of each module connec-ted to the input steering terminal of the next module.          Then, in use,  current flows from one power line to a power terminal of one module, through its output steer-ing terminal to the input terminal of the next module, through that module and to the other power line.  Thus, with each detonating pulse, a detonator is fused and one of the elements passes into its second conducting state.          As the detonator goes into a non-conducting configura-tion the next pulse is steered via the element that is now conducting to the next module.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus  for fitting a sealing strip to  a  mounting flange  running around a motor vehicle door opening is disclosed.   The  sealing strip is preferably  in  the form  of a closed ring and is longitudinally resilient having  a channel-shaped gripping section  and a  soft sealing  section.   A jig is in the form of  an  outer plate  which  is larger in area than the door  opening defined  by  the flange.   The strip in ring  form  is placed on this outer plate and then pulled inwardly by gripping  fingers  so as to distort it  into  a  shape limited  by arm ends and to take up a peripheral  size less  than the size of the door opening.  The jig then positions  the  seal,  which is  partially  compressed between the outer plate and an inner plate, within the door opening.  The gripping fingers are then  released and  the  arm ends move outwardly so as to  press  the gripping  section     of the sealing  strip  onto  the flange.     6CW05:6CW5
