Abstract: - 33 -             RCA 71,205 Abstract of the Disclosure A gain controlled amplifier is provided which is capable of handling a wide range of input signal levels with-out the need for input signal attenuation.  A transistor is arranged in a common emitter amplifier configuration and includes a PIN diode as a controllable impedance in the emitter circuit.  An input signal and a gain control voltage are applied at the base of the transistor.  As the input signal level increases, the gain control voltage is decreased, causing an increase in the substantially resistive impedance of the PIN diode, which bears a constant relationship to the decreasing gain control voltage (i.e.,a linear relationship on a semi-logarithmic plot). The gain of the transistor amplifier is thereby reduced.  At high input signal levels, the impe-dance of the PIN diode comprises a large resistive component in parallel with a large reactive (i.e., small capacitive) component at the emitter of the transistor, thereby affording substantial  gain reduction.  A novel PIN diode is provided for use in such a gain controlled amplifier, comprising a first localized region of high resistivity semiconductor material having a substantially planar surface.  Second and third localized regions of one type conductivity are located in the high resistivity region adjacent to the surface.  A fourth localized region of opposite type conductivity is located in the high resistivity region adjacent to the surface and intermediate the second and third localized regions, and is separated laterally from the first and second regions by zones of the high resistivity material.

Abstract: USE OF ACID AS AN ANALYSIS AID     IN SALTED MEAT SAMPLES                 Abstract of the Disclosure The accurate determination of the fat, moisture, and protein content of salt added meats by means of thermal extraction is complicated by the enhanced fat and moisture binding capability that salt gives to meat proteins.  This effect is counteracted by the addition of a controlled amount of acid to a salted meat sample which lowers the pH of the meat proteins below their isoelectric points. In a preferred embodiment, citric acid is mixed with a salted meat sample and the sample is then exposed to microwave energy for a time sufficient to achieve a relatively constant chemical analysis in the residue which is related to the amount of fat and moisture rendered from the sample.

Abstract: TESTING METHOD FOR DETERMINING THE MAGNETIC PROPERTIES  OF FERROMAGNETIC POWDERS            ABSTRACT OF THE DISCLOSURE The invention relates to a method permitting the magne-tic properties of ferromagnetic powders which are used for the preparation of heavy media for the float-sink dressing of minerals, to be tested. To this end, the invention pro-vides for the ferromagnetic powder to be magnetized in a magnetic steady field at a field strength within the range 600 to 1000 amperes per cm and the magnetized ferromagnetic powder to be demagnetized in a cyclicly decreasing magnetic alternating field at a field strength within the range 1000 to 1500 amperes per cm. Next, the ferromagnetic powder so pre-treated is heaped up, in the center portion of a circular plate made from dielectric material and the circular plate is placed on an iron core-provided coil. An alternating current voltage of 180 to 260 volts is applied to the coil, thereby effecting the occurrence of alternating fields of 180 to 220 amperes per cm in the center portion of the cir-cular plate. The ferromagnetic powder heaped up is observed for the figure it is forming under the influence of the al-ternating fields. The formation of a closed figure around the center portion of the plate indicates unlimited quali-fication of the ferromagnetic powder for use in a heavy medium suspension.

Abstract: Abstract An orderwire communication scheme for a fiber optic communication network includes terminal station equipment associated with the central offices at opposite ends of the network and signal regenerator equipment at the repeater sites disposed between the terminal stations.  The communication format along the link is a data-over-voice scheme, the data being digitally encoded on an FSK modulated carrier.  In carrying out supervisory functions with respect to each of the stations along the link, command messages are conveyed from the terminal stations at one of the central offices to respective stations along the link in the form of command instructions.          Each command message from a central office's terminal station contains the address of the recipient station for whom the message is intended followed by a specific encoded instruction.          The instruction may contain a request for information from the addressed site as to equipment conditions at the site and/or a directive that the equipment at the site perform a particular task.  In reply to the command message sent to it, the addressed site transmits a response message back to the source station, representative of the status of a particular equipment condition or operation as requested by the command instruction.          In this manner, supervisory personnel at each central office may remotely monitor and control the operation of the communicative equipment at the various sites along the link and thereby take correction maintenance or protection channel substitution action where and when required.  The digital message transmission scheme also provides facility for fault/alarm reporting, testing the bit error rate of individual channels of the repeater and the transceiver equipment at each terminal station when requested, and is used for paging signalling between central offices.

It has been found that this reduction leach will proceed if there is present at least two moles  of copper for each mole of sulfide and elemental sulfur, and a reducing agent able to complete all reduction reactions that yield chalcocite.  Metallic copper powder has been found an adequate reducing agent and is able to supply any Cu needed to form Cu2S.  Iron powder or hydrogen gas under pressure are also operative reducing agents. This reduction leach is operative also on calcines from which sul-fur has been volatilized, in which case a metallic copper concentrate is formed.  Various flowsheets incorporating this reduction leach are described.  This reduction leaching avoids H2S evolution,

Abstract: JC/sl 22789 1-5-81 VENEER LATHE APPARATUS AND METHOD USING INDEPENDENTLY ADJUSTABLE POWERED BACK-UP ROLL                 Abstract of Disclosure A veneer lathe log peeling apparatus and method of producing wood veneer are disclosed employing a powered back-up roll for adding torque to the rotation of the log and preventing deflection of log cores of small diameter.  The powered roll and an idler roll are positioned in contact with the side of the log in spaced relationship so that the resultant force vector of the cutting forces produced by the lathe knife and the nose bar is directed between the idler roll and the powered roll.  The angular and radial positions of the idler roll and the power roll relative to each other and with respect to the axis of rotation of the log are independently adjusted by an automatic control means which may be operated by a pair of cams or by a computer, in response to decreases in the diameter of the log being peeled.  The automatic control means preferably includes separate servo means for adjusting the positions of the powered roll and the idler roll and the speed of the powered roll in response to output control signals of a microprocessor computer having input signals corresponding to the diameter of the log, the speed of rotation of the log and the veneer thickness.  Preferably the idler roll is positioned on the opposite side of the log from the knife means and the powered roll is positioned above such knife means.          As a result, the amount of additional torque applied to the log by the power roll automatically increases when the log core tends to deflect thereby self-compensating to prevent such deflection.
