IPC: G01S7/60
Filed: 1969-07-15
Abstract: 1,252,841. Echo-sounding; facsimile apparatus. FURQNO ELECTRIC CO. Ltd. 15 July, 1969 [15 July, 1968; 5 Dec., 1968], No. 35686/69. Headings H4D and H4F. [Also in Division G1] In a system for recording an electrical signal (e.g. in a facsimile recorder or echo-sounder) and comprising a row of stylus-like pen electrodes arranged across a longitudinally moving web of recording paper, periodic switching signals control the gating of the electrical signal to the electrodes in turn and the record scale over part of the web width is changed by changing the period of the switching signals.  The Fig. 4 embodiment (whose signal timing is given in Fig. 6) is for use with telemetry apparatus (Fig. 5, not shown) carried by a fishing net and comprising upward echo-sounding, downward echo-sounding and temperature sensing equipment, data from this equipment being modulated serially on to an acoustic carrier which is transmitted to receiver 72. The demodulated receiver signal a comprises sync. pulses 51, pulse 54 whose time position represents water temperature, downward echosounding pulse 58 and its fish and bottom echoes 59, 60, upward echo-sounding pulse 64 and its fish echoes 65, 66 and water surface echo 67. Sync. pulse 51 opens gate 76 to pass clock pulses d of rate q from source 77 to frequency divider 78 having outputs f, g at rates q/2 and q/4. The divider outputs drive a register 83 which gives output pulses h on lines u-z when preselected counts are reached in the register. These pulses set bi-stables 91, 92, 93 which in turn control gates 79, 80, 81. Pulses appear on outputs 103 of matrix 102 in sequence in response to any pulses being received via counter 82 from gate 79, 80 or 81, and selected 103 output pulses are used to reset the bi-stables. For recording pulse 54 as a time/temperature plot 108 on paper 106, gate 79 applies rate q pulses to matrix 102 in the interval between the u output of register 83 and the reset pulse on the rth matrix output, whereby the rth to right-hand electrodes of row 105 are scanned in turn. For recording the downward echo-sounding data between the (r+1)th and (r+s)th electrodes, one of gates 79, 80, 81 (according to the setting of scaleselector switch 94) drives matrix 102 in the interval between the x output of register 83 and the reset pulse on the (r+s)th matrix output. The upward echo-sounding data is similarly recorded between the (r + s + 1)th and left-hand electrodes. Finally, the z output of register 83 closes gate 76 and resets counter 82 for a new scan. In a simpler embodiment (Fig. 1, not shown) the pen electrodes are scanned by means of a switching signal which appears in turn on the several output lines of a counter (5) comprising cascaded binary frequency dividing stages and AND gates. The counter input is selected from one of two oscillators (1, 2) running at different respective frequencies.

The casing 6 has a high-pressure chamber 6<SP>1</SP> to which oil is supplied by a pump P from a sump 10 connected by a pipe 9 to a low-pressure chamber 6<SP>11</SP> of the casing 6. The bearings 4, 5 are mounted in a sleeve 7 having radial apertures 7a therein leading from the chamber 6<SP>1</SP> to the shaft and bearings 4, 5. The oil is forced between the shaft and the bearings and is then transferred to the chamber 6<SP>11</SP> via passages 3, 3<SP>1</SP>, 6d, 6e from where it is returned to the sump 10 via the pipe 9. The chambers 6<SP>1</SP>, 6<SP>11</SP> are also connected by a pipe 12 which acts as an overflow and serves to equalize the pressure in the chambers when the oil level is below a mouth 12<SP>1</SP> of the pipe 12 which is supported by an end 6g of the chamber 6. Sealing of packing points 17, 18 is effected by air under pressure received from the blower via an annular channel 13, a channel 13a and axial channels 16. The turbine is secured to the casing 6 by radial extensions 14 having radiallyextending slots with edges 14a which serve as guides for screws 15 having cylindrical portions 14b thereon, so that the turbine can expand without being unduly stressed. The blower casing 2, having flanges 2a, is clamped to a stepped portion 6f of the casing 6 by screws 11<SP>1</SP> and a member 11. Both the turbine and the blower can be oriented relatively to the case 6 prior to locking thereto. Specifications 893,509 and 893,576 are referred to.
