Abstract: ABSTRACT           Improvements in or relating to The Treatment of Molten Metal The invention is directed to a method of and apparatus for, introducing into a bath of molten metal (eg a ferrous metal) contained in a vessel an alloying component (eg lead) or a reagent. The method includes the steps of connecting a plurality of plugs or nozzles located in the bottom and/or sides of the vessel to supplies of gas (eg argon) under pressure, and causing gas to be introduced simultaneously through the plugs or nozzles to produce individual gas flows which pass upwardly through the metal bath to create areas of turbulence on the bath surface.   The areas of turbulence interact to produce on the bath surface a relatively quiescent region and it is into this relatively quiescent region that the required quantity of alloying component or reagent is added.

Abstract: Abstract A multiband local oscillator of a television tuner comprises a common collector transistor amplifier, a feedback circuit for conditioning the amplifier to oscillate in the wide range of frequencies for VHF broadcast and cable channels and a multiband tuning circuit coupled to the base electrode of the transistor. Bandswitching signals are applied to the multiband tuning circuit to produce tuned circuit configurations for the various frequency bands.  When one band is selected, the corresponding bandswitching signal is coupled to the capacitive feedback network to modify it so as to inhibit out-of-band oscillations due to parasitic elements of the tuning circuit.

Abstract: TRANSMISSION SYSTEM USING FORWARD ERROR CORRECTION          ABSTRACT OF THE DISCLOSURE        In a high-speed fiber-optic tranmission system, data streams are synchronized using fixed stuffing before being multiplexed for transmission.  The fixed stuffing information is replaced with forward error correction (FEC) information, whereby FEC is effected without any increase in transmission speed.  FEC information blocks of each data stream can be synchronized to the frame timing of the transmission system, or they can be relatively unsynchronized.  In the latter case, an FEC decoder acts in a self-framing manner to synchronize itself to the FEC information blocks of the respective data stream.

Abstract: ABSTRACT OF THE DISCLOSURE    Under the condition where a plurality of back-ground noise sources exists, there are arranged a first receiver,  primarily  receiving  desired  voice,  and  a plurality of second receivers each primarily receiving noise  from  a  corresponding  noise  source.   Filter coefficients  of  equivalent  noise-producing  filters, each having  a  frequency  transmission  characteristic equivalent  to  that  of  transmission  path from  its corresponding noise source to the first receiver, are estimated based upon mutual-correlation  coefficients among the outputs of the first and second receivers and auto-correlation coefficients of the respective outputs of the second receivers.   The noise signals from the equivalent noise-producing filters are subtracted from the output of the first receiver, thereby canceling the background noise.   The filter coefficients estimation may be performed by using a maximum of the mutual-cor-relation coefficients between the outputs of the first receiver and the respective second receivers.

Abstract: In an automatic aspirator-transfer valve controlling the delivery of washing fluid from a supply (M) to a cleaning gun (B) and having a valving piston (2) movable between a first or rinsing position, in which it opens bypass conduits (15) bypassing an injector (3,21,4) and a second or washing position in which it closes said bypass conduit (15) and enables the injector (3,21,4) to aspirate washing fluid from a reservoir (not shown) through a non-return valve (11), a side inlet (5) and a conduit (22) to its side inlet (21), the novel aspect is that the side inlet conduit (22) is separated from the space within the housing bore (20), in which the valving piston (2) can slide. 
<??>In this manner it is avoided that a portion of the washing agent may fill the space within the housing bore (20) and leave the valve in the form of a "plug" when changing from the washing mode (Bottom Figure) to the rinsing mode , thus avoiding both the issuing of dangerously high concentrations and unnecessary waste of washing agent.

The reaction is carried out in the presence of a carboxypeptidase in an aqueous solution or dispersion at pH 5-10.5 and at a temperature of preferably 20-50 degrees C. This reaction gives a peptide from which an R3, an R4 or an N-terminal protecting group can be cleaved off if required. <IMAGE>

Abstract: A time division duplex transceiver incorporating a dual conversion superheterodyne receiver, and in which the first receiver local oscillator (6) doubles as the frequency source for the transmitter. The oscillator (6) is a voltage controlled oscillator VCO forming part of a mixer-type phase locked loop (21). Frequency deviation in the loop is achieved by mixing the VCO output with a selected harmonic of the output of the second receiver local oscillator (11). The reference oscillator is a crystal controlled oscillator (41) whose output is switched as between transmit mode and receive mode at a switch (55) before being passed to the loop phase detector (28). The transceiver is able to rapidly and repeatedly alternate beween transmit and receive modes and is thus well suited to time division multiplex operation.
