Abstract: ABSTRACT OF THE DISCLOSURE        The connector system includes a radio mounted receptacle with an integral transfer switch, and a separate connector and cable for interface with external radio frequency (R.F.) circuits, and provides a method of connecting external R.F. circuits to a portable radio and for simultaneously and auto-matically transferring the internal radio circuits from an integral radio antenna to the receptacle.  The integral transfer switch of the receptacle connector includes a movable conductive plunger retained within a conducting sleeve and adapted to slide in an insulator between a first position at which the head of the plunger engages an inturned end of the sleeve, and a second position in which the plunger engages a flexible contact connected to the radio circuit and moves it away from a contact connected to the self-contained antenna.  A connector  connected to a coaxial line, which may be connected to external radio frequency signal source, has an outer conductor adapted to connect to the sleeve and an inner conductor which enters the sleeve and engages the plunger to make electrical connection therewith and move the same to the second position.  This disconnects the self-contained antenna from the radio circuit and connects the coaxial line thereto.  The sleeve, plunger, and inner and outer conductors provide a matched impedance connection from the external source to the radio circuit.  The external connector can be manually connected to the radio mounted receptacle connector or automatically coupled thereto when the portable radio is positioned in a carrying housing.

Abstract: LOW SPECIFIC GRAVITY MAGNETIC CARRIER MATERIALS     ABSTRACT OF THE DISCLOSURE    Electrostatographic carrier materials having low bulk densities and high magnetic permeabilities are obtained by impregnating low density porous silicaceous particles with a magnetic or magnetically-attractable transition metal or metal oxide thereof.  The low density magnetic composite carrier par-ticles are prepared by the thermal decomposition of transistion metal carbonyls in the presence of the silicaceous particles with a suitable suspending medium.  The contents are heated with agitation so that carbonyl boils and the mixture is refluxed, in the absence of air and moisture, until the temperature rises to that of the suspending medium whereupon impregnation of the silicaceous particles with elemental metal and/or metal oxide is complete.  The mixture is cooled, the beads washed, air-dried, and recovered.  When mixed with toner particles the aforementioned carrier materials experience sig-nificantly reduced toner impaction levels.
