Title: Television system with zoom capability for at least one inset picture
Inventor: DUFFIELD DAVID J
IPC: H04N5/45
Filed: 1990-02-22
Abstract: A television system including a memory for storing subsampled fields in different sectors corresponding to respective small pictures of a rectangular multi-picture array, includes apparatus for expanding the subsampled fields, preferably to full-screen size, as they are read-out of the memory. When the stored sub-sampled fields correspond to different fields of the same video signal, the arrangement provides for a reanimated version of multi-picture array in a so-called "instant replay" mode of operation.

Title: Process for recovery of gold from refractory ores
Inventor: THOMAS KENNETH G
IPC: C22B3/04

Abstract: 4LH                                              ABR 5080.1 PATENT     PROCESS FOR RECOVERY OF GOLD FROM REFRACTORY ORES            Abstract of the Disclosure The present invention is directed to an improvement in a process for the recovery of gold from refractory sulfidic auriferous ores.  The process comprises treatment of a slurry of the ore with sulfuric acid, oxidizing the treated slurry with oxygen gas under pressure in the presence of sulfuric acid,  neutralizing  the  oxidized  slurry,  cyanidizing  the neutralized slurry to leach gold therefrom, and recovering gold from the resultant leachate.   In accordance with the improvement, the oxidized slurry is contacted with wash water in an oxidized pulp washing stage, wash water as introduced into the pulp washing stage being at a temperature lower than that of the oxidized slurry.  A partial liquid/solids separation  is effected within the washing  stage,  and  a relatively high solids fraction comprising washed oxidized slurry and a liquid fraction comprising spent wash liquor are separately removed from the washing stage.  The spent wash liquor is neutralized by mixing it with a base which forms a substantially insoluble  sulfate  salt  upon  reaction with sulfuric acid,  after which the neutralized wash liquor is cooled.   Precipitation  solids  are  separated  from  the neutralized spent wash liquor and the cooled neutralized wash liquor is recycled to the pulp washing stage to provide wash water for contacting the oxidized slurry.

Title: Continuous flow fuel control system
Inventor: BAK MICHAEL J
IPC: F16K31/06
Filed: 1990-05-15
Abstract: ABSTRACT           A fuel  control  system for providing  steady state fuel flow to a gas-turbine  engine  comprises  a pulse-width modulated,  solenoid-operated fuel metering valve,  an  engine  speed  transducer,  and  a  remote microprocessor  communicating with  the  valve  and  the speed transducer through an optical fiber.  The valve is operated by a direct current signal which is pulsed at a frequency  substantially  higher  than  the  natural frequency of the valve spring/plunger system, whereby the plunger remains axially displaced from the valve seat to provide continuous flow through the valve.  The amount of axial plunger displacement and,  hence,  the fuel flow rate are prescribed by the pulse width of the signal directed through the valve.

Inventor: GROLLMANN PETER
IPC: G01C19/68
Filed: 1990-10-04
Abstract: In order to avoid a lock-in effect, and in order to avoid scale factor nonlinearities, particularly in the case of low rates  of  rotation,  it  is  proposed  for  a  fiber  optic interferometer rate-of-rotation sensor which is reset by phase ramp via a digital control circuit to undertake the reversal, necessary to obtain the scale factor error information, of a reciprocal, alternating phase shift not as a function of the angle  of  rotation,  but  with  a fixed  timing,  which  can advantageously be synchronized with the gyroscope modulation frequency.  The advantage of the invention is that even in the case of low rates of rotation, in particular, a scale factor error correction is possible and a lock-in effect, caused by variations in bias in the case of the modulation deviation reversal, is avoided.

Title: Device with a multiplicity of independent, identical oscillators operating synchronously
Inventor: KISLOVSKI ANDRE
IPC: G05F1/67
Filed: 1990-07-06
Abstract: Abstract A device of the invention has several saw tooth type oscillators, each having a synchronization unit and a pulse distribution or emitter unit allocated to it.  Each oscillator  has  two  outputs,  one  constituting  an  open collector point.  The synchronization units each have two diodes  connected at opposite  terminals,  as well  as  a transistor connected as an amplifier.  One of the output terminals is in each case connected to an open collector point,  the  other  output  terminal is  either  free  or connected via a line to the relevant output terminals of the other synchronization units.  If an output terminal is free, then the allocated oscillator oscillates freely.  If the output terminal is connected to the line, however, then the allocated oscillators oscillate in synchronization.  The arrangement serves to synchronize the inverters, which pump the current from solar cells into a battery with constantly maximum efficiency.

The method is based on a modification of the conventional HPLC gradient commonly used to elute and separate all PTH amino acids of interest in automated and manual sequencing.  In one embodiment, using automated instruments manufactured by Applied Biosystems, gradient modification is achieved by changing the manufacturer-supplied gradient program which controls the operation of the HPLC pumps in the instrument. Using the methods of the present invention, the correct and reliable assignment of tryptophan residues is possible and was reproducible over time, even with small sample sizes.
