A dragnet N (Fig. 1) towed by a vessel SP is provided with electro-acoustic transducers V2, V3 connected over a cable C with known echo sounding equipment M in the vessel which itself is equipped with an electro-acoustic transducer VI. In operation transducers VI and V2 are energized simultaneously by respective oscillators O1 02 (Fig. 2) the operation of O1 also initiating a time-base sweep circuit 3 for a cathode-ray oscilloscope BM. Echo signals received by VI are displayed on the oscilloscope and are also supplied to a pen recorder RM. On reception of echo signals by V2 a circuit Q operates to initiate another sweep of circuit S and also triggers oscillator 03 which energizes transducer V3. Echo signals received by the latter are then displayed on the oscilloscope and are also recorded on RM. Fig. 3 shows typical displays produced on the pen recorder (31), (33) and on the oscilloscope (32), (34). Referring to (31) the trace indicates the operation of transducer VI and shows the transmitted pulse l1, fish shoal fl (Fl in Fig. 1) and sea bottom b. On the oscilloscope display (32) the fish shoal is shown alone by the selection of a suitable time-base speed. Diagrams (33) and (34) show in similar manner the respective pen-recorder and oscilloscope displays produced by operation of transducer V3. Since the sweep against with echoes received by the latter are displayed is triggered by echoes from the surface received by transducer V2 an expanded showing of the conditions at the mouth of the dragnet is produced. Control equipment is illustrated in Fig. 4 (not shown) allowing the selective production (by switching means) of (1) indications due to transducers VI and V3; (2) indications due to transducer VI only; (3) indications due to transducer V3 only. Explanatory waveforms are indicated in Fig. 5 (not shown)

[Class 53] A dry cell, Fig. 1, comprises a zinc or magnesium cup 40 containing amalgamated zinc powder or shot 42. Above this layer is a layer of jelly electrolyte 43 and a depolarizer mix 49. The cup 40 is enclosed in a moulded rubber or plastic cup 44 which is engaged by a flange 48 on an iron or steel cup 46 which closes the upper part of the cell and is provided with gas exits 51. An insulating ring 45 may be provided to cover the edge of the electrolyte 43. Cup 46 and a rivet 52 form the terminals of the cell. The depolarizer mix 49 may consist of mercuric oxide and graphite moistened with potassium hydroxide solution. Other depolarizers may be used such as oxides of copper, silver, and lead, permanganites of copper, silver, lead, manganese and mercury, permanganates of potassium, calcium, silver, and copper, which may be mixed with potassium carbonate or magnesium silicate and impregnated with a water repellent substance such as paraffin. The electrolyte is a solution of potassium, sodium or ammonium hydroxide, with or without some zincate, which has been converted into a jelly by an alkali salt of carboxy methyl cellulose. The layer 43 may be made by moulding the mixture into flat sheet form and after it has set punching out discs of the required size. Another method consists in filling a glass tube with the mixture, allowing it to set, and then pushing out the cylinder of electrolyte and cutting it into slices. The electrolyte may also be moulded in position in the cup 40. Another form of the electrolyte layer consists of porous paper or other material which is saturated under vacuum with the unjellified solution and then placed between stainless steel plates and heated to cause the electrolyte to gelatinize. Discs are then punched from the sheet. The bottom surface of the zinc cup 40 may be left bare to form the negative terminal, the rivet 52 being dispensed with. The cells may be stacked to form a battery. Fig. 11 shows a modified form of cell in which a metal can 10 has a corrugated and perforated zinc sheet 11 in contact with its inner surface. A steel- or silver-plated metal rod 14 which may be threaded, grooved, or otherwise provided with projections is surrounded by the depolarizer 13 which is separated from the zinc electrode by the jelly electrolyte 12. To prevent creepage of electrolyte over the top edge of the zinc can it is dipped into a solution of sodium silicate which forms a film 24. The cathode is centred by triangular mica washers 16, 17 and the cell is closed by paper washers 18, 19, a cement sealing 20 and a fibre washer 21. The outer surface of the can 10 is covered with paper 23 and a lacquer coating 24. The can may be made of zinc, cadmium, magnesium, copper, which may be silver-plated, or an alloy of copper with cadmium, zinc or magnesium. Specification 646,800 is referred to.

Title: Improvements relating to chromium-containing monoazo dyestuffs of the pyrazolone series
IPC: C09B45/16
Filed: 1954-07-16
Abstract: The invention comprises dyestuffs of formula (F-Cr-F1)-M where M is an alkali metal or ammonium cation, F is a coordinated dyestuff of formula <FORM:0762905/IV(b)/1> and F1 is as F except that R1, Y1 and X1 are respectively R2, Y2 and X2 and where R1 is an alkyl or cycloalkyl group of 4-8 carbon atoms, R2 is Cl or an alkyl group of 1-5 carbon atoms, X1 and X2 are -CH3, -NH2, -NHCH3 or -NHC2H4OH and Y1 and Y2 are H, -CH3 or Cl.  They are made by treating mixtures of the above monoazo dyestuffs corresponding to F1 and F with chromium-yielding agents so that there are two dyestuff molecules bound in complex linkage with one chromium atom.  Diazo components specified for dyestuffs corresponding to F are 4-n-butyl-, -tert. butyl-, -n-amyl-, -tert. amyl-, cyclohexyl- and iso-octyl-6-nitro-2-amino-phenol and coupling components indicated are pyrazolones substituted in the phenyl radicle, preferably in the 3- or 4-position, with, e.g. SO2NH2, -SO2NHCH3, -SO2NHC2H4OH or SO2CH3 groups and which may also contain CH3 or Cl groups in the, e.g. 4- or 6-position.  Diazo components specified for dyestuffs corresponding to F1 are 4-methyl-, -isopropyl, -n-butyl-, -tert. butyl-, -n-amyl- and -tert. amyl-6-nitro-2-aminophenol the coupling components being as for F.  For dyeing purposes sufficient water solubility is only obtained if a strongly hydrophilic group, e.g. -SO2NH2, is present although such groups too strongly reduce the drawing power on to wool from neutral baths.  Hence it is of advantage to combine a dyestuff corresponding to F, the metal complex of which has too little water solubility, with an easily water-soluble dyestuff corresponding to F1, the metal complex of which has insufficient drawing power from neutral baths. Advantageously the same coupling component is used in the preparation of the mixed dyestuffs and in this modification the following combinations are specified: -6-nitro-4-methyl-2-amino-phenol and 6-nitro-4-tert. butyl or amyl-2-amino-1-phenol diazotized and coupled with 1-(31-or 41-sulphonic acid amino-phenyl)-, -(61-chloro- or -methyl-31-sulphonic acid amidophenyl)- or -(41-chloro or -methyl-31-sulphonic acid amidophenyl)-3-methyl-5-pyrazolone or their corresponding sulphonic acid methyl- or methylethanol-amides. Chroming is performed in conventional fashion.  For dyeing purposes the products may be mixed with salts such as sodium carbonate or trisodium phosphate and wetting and dispersing agents such as soap and synthetic detergents.  Natural and synthetic polypeptide fibres are dyed from neutral to weakly acid baths in red shades.  Examples and a table are provided illustrating the preparation of a variety of chromed dyestuffs from certain of the above specified components and their use in dyeing wool, additional specified components being 6-nitro-4-chloro-2-amino-phenol and 1-(31- and 41-methylsulphenyl)- and -(21-chloro-51-methyl-sulphenyl) - phenyl - 3 - methyl - 5 - pyrazolone.
