Title: Multichannel underwater acoustic telemetering system
IPC: G08C23/02
Filed: 1967-10-06
Abstract: 1,206,967. Digital telemetering. BENTHOS Inc. 6 Oct., 1967 [10 Oct., 1966], No. 45953/67. Heading G4H. In a system of underwater acoustic telemetering there is transmitted a first series of acoustic pulses each being followed by a timed acoustic pulse, the interval representing the variable being telemetered, there being means for transmitting a third pulse which indicates by its presence or absence and, if present, by its timing, the variable being transmitted. The apparatus may be used with a trawl net to monitor the depth, mouth-opening and water temperature. Representative signals are transmitted each second for a period of ten or twenty seconds. The acoustic pulses take the form of an audio-frequency " ping ". The start pulse is at 11 kc/s. and is transmitted each second, being gated at 62 from oscillator 56 to the acoustic transducer 76 by 1 pulse/sec, clock pulses from source 68. The value pulse is a 13 kc/s. ping from oscillator 60 gated at the appropriate differential time to the transducer 76. The value in the form of a D.C. voltage is applied to a variable delay 54 which delays a clock pulse from 68 a corresponding amount. Transducers 34, 28, 36 for head rope depth, foot rope depth and temperature provide signals representing these variables. The opening of the mouth of the net is derived by subtracting at 39 the signals representing the head rope depth and the foot rope depth. The depth signal is gated at 38 to the delay 54 for a period of 20 seconds, i.e. the data is transmitted 20 times. The mouth opening and temperature signals are gated at 40 and 42 for periods of ten seconds each. Gates 38, 40, 42 are controlled by a sequencer 50 receiving pulses from clock 68. When temperature is being transmitted the third signal, which is a 12 kc/s. signal, is also sent at 7 milliseconds after the start pulse. The clock pulse is passed by gate 82 through 7 m/s. delay 78 to form a marker signal opening the 12 kc/s. gate 64. When mouth opening is being transmitted the marker pulse is again sent out at 15 m/s. using gate 84 and delay 80. The acoustic pulses are received at the trawler by a hydrophone and separated by filters into signals on different leads. The start pulse sets a flip-flop and the data pulse resets it. The output of the flip-flop is used to open a gate allowing pulses to pass to a counter. The marker pulse is applied to a circuit of gates and delays which determines whether it is present and if so whether at 7 m/s. or 15 m/s. delay. There are separate clock pulse sources for temperature and depth and the appropriate one is selected to give a counter reading in the desired units. Panels are illuminated to indicate the meaning of the value displayed on the counter.

Title: A process for producing alloyed metal powders for use in powder metallurgy
IPC: B22F3/00
Filed: 1962-12-19
Abstract: A process for preparing a porous metal alloy product comprises mixing reducible metal compounds (e.g. oxides), heating the mixture under non-reducing conditions to obtain diffusion and homogenization and then reducing the mixture at a temperature below the melting point of the starting materials and the product. The reducible metal compounds are ground and mixed and preferably compacted or extruded into pellets, heated in air, oxygen or other oxygen-containing gas (e.g. for 1 hour at 1000  DEG C.) and the reduction is carried out either in the comminuted or in the compacted form (e.g. at 900-1100  DEG C. in hydrogen).  The process may be carried out in a continuous or semi-continuous manner using a series of heating chambers at different temperatures and under different atmospheres.  The starting powder may be mixed with a solid reducing agent (e.g. coke or charcoal) since reduction does not occur at the tempeautres used for the diffusion treatment. The alloy may then be crushed and used in powder metallurgy applications.  In an example an alloy comprising: .Fe. .Mo.0.2% .Mn.0.48% .Ni.1.5% was crushed to 65 U.S. mesh size, mixed with graphite, cold pressed and sintered in hydrogen at 1120 DEG C.  Oxides mentioned as suitable for use in the process of the invention are MnO2, MnO, Fe2O3, Fe3O4, FeO, NiO, CoO, MoO3, WO3, PbO, CuO, SnO2, Ag2O, Cu2O and CdO.
