Abstract: ABSTRACT A radio transceiver includes an antenna, a transmitter, a receiver and an antenna switching circuit for selectively connecting the transmitter and the receiver to the antenna in response to a transmission/receipt control signal.  The antenna switching circuit is made up of a series connection of a first diode and an inductor, and a second diode and a filter is connected to the antenna and the antenna switching circuit.  The improvement involves connecting the series connection between one end of the filter adjacent to the antenna and a given potential point, the junction of the first diode and the inductor being connected to an input of the receiver and the second diode being connected between the other end of the filter and an output of the transmitter. The invention solves the problem of loss of receiver sensitivity complementary to insertion loss which prior-systems experience.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus and process for the reduction in a plasma stream of a feed material including a comminuted metal oxide,  a slag former and a reductant utilizing an enclosed horizontal reactor having a reduction chamber and a  filter  chamber  therein  separated by a either common partition having a plurality of holes therethrough or a refractory  lined  passageway.   Coke  filter media in the filter chamber act to filter out entrained molten metal contained  in  the  plasma  stream  with  the  partition  or passageway preventing entry of the coke from the filter chamber  into  the metal bath contained  in the reduction chamber thereby limiting the amount of carbon entering the metal produced.  Unreduced metal oxide is provided in the slag layer of the metal bath to maintain the stoichiometric ratio between the metal  and reductant  in the reduction chamber.  In alternate embodiments of the invention,  the reactor is provided with a sloped floor or with a rocker mechanism to control the residence time of the metal with the coke thus limiting the amount of carbon entering the metal product.  The exhausted plasma stream can be recycled for preheating and prereducing the incoming feed material.

Abstract: ABSTRACT     A method for determining the onset of nucleation wherein a zone of a translucent fluid in which crystals may be formed is illuminated by a beam of light.  When crystallization commences the crystals in the illuminated zone reflect and scatter light.  Some of the scattered light is collected and transmitted to a light sensitive detector operable to generate a signal indicative of nucleation.  Upon detection of nucleation either manual or automatic procedures may be instituted to modify the crystal-lization process in an appropriate manner.

Abstract: ABSTRACT OF THE DISCLOSURE A recording apparatus for a video signal in which first and second heads for recording and reproducing are attached through electrostrictive elements to a rotary drum with an angular spacing of substantially 180° therebetween.  When a video signal is recorded, a pilot signal recorded by the first head over a predetermined interval is reproduced by the second head while a pilot signal recorded by the second head and spaced apart by a predetermined number of recording tracks is reproduced by the first head.  Reproduced levels of the pilot signals are compared so as to control a drive voltage for the electrostrictive elements and thus to adjust a step difference between the first and second heads in the recording mode.

Abstract: NONDESTRUCTIVE READOUT OF A LATENT ELECTROSTATIC IMAGE     FORMED ON AN INSULATING MATERIAL     ABSTRACT OF THE DISCLOSURE        A  method  and  apparatus  are  described  for  the nondestructive readout of a latent electrostatic image formed on a sheet or layer of insulating material.  A sheet, or layer of  semiconductor material  is disposed  in relatively  close proximity to the insulating material.  The latent electrostatic image  formed on the  insulating material  causes a  surface depletion layer to be produced by induction at the surface of the semiconductor material.  The location and distribution of the accumulated charges on the semiconductor material are read out  as  analog electrical  signals  corresponding  to the  ac surface photovoltage induced on the semiconductor material as the semiconductor material is scanned with a low intensity modulated light beam of appropriate wavelength, the magnitude of the analog signals depending on the local charge density.          The analog electrical signals so obtained are then digitized, processed and stored and/or displayed.

Abstract: ELECTRO-MECHANICAL INTEGRATOR                     ABSTRACT OF THE DISCLOSURE          An electronic integrator for integrating a linear voltage signal utilizes a Voltage-To-Frequency converter for converting the voltage to input frequency.  A binary counter counts pulses of the input frequency.  The binary counter generates a first operating frequency which is applied to a scaling circuit and another calibration frequency which has a much higher rate than the operating frequency.  Both, however are proportional to the input frequency.  The scaling circuit scales the operating frequency to a selected extent to form a counting signal.  Using the double pole switch, either the calibration frequency or the counting frequency are applied to a pulse counter which is either used to integrate the input voltage signal by counting up pulses of the scaled counting signal, or the integrator can be calibrated using the calibration frequency which quickly  increments the pulse counter.
