Abstract: 1,077,823. Echo-sounding. MORSKA OBSLUGA RADIOWA STATKOW. Aug. 31, 1964 [Aug. 29, 1963; May 27. 1964], No. 35500/64. Heading H4D. In a pulse echo-sounder for depth-recording or fish location, the echo period is measured by gating a clock-pulse counter on with the transmitted pulse and off with the echo pulse, the counter feeding a digital display with a stored read-out in terms of distance. In the embodiment of Fig. 2, ultrasonic transmitter (2) drives a magnetostrictive transmitting-receiving transducer (4) and echo pulses are amplified by an amplifier (3) (these may form part of a known system). In a unit (5), pulses from transmitter (2) and amplifier (3) are shaped and used to open a gate (7) to feed clock pulses from a generator (6) to a binary counter (8) during the echo period. A bank of relays (9) converts the binary count to a three-figure decimal reading which is displayed on digital indicator lamps in a unit (10) and in slave read-out units (11), and which is printed out on paper tape by a printer (12). The frequency of the clock pulses from generator (6) may have one of four predetermined values in the range 390 c/s. to 7500 c/s. to give a depth reading in decimetres, metres, feet or fathoms, the particular unit of measurement being displayed. In order to prevent flicker of the read-out the relays in the bank (9) are provided with hold-in contacts and store the read-out information until deenergized simultaneously by a control circuit (13). A timing unit (15) determines the rate at which echo sounding measurements in display (10) are changed and a recording device (16) may be used to provide a conventional echo gram.

Title: Improvements in the manufacture and production of crotonaldehyde
IPC: C07C45/66
Filed: 1936-12-30
Abstract: Crotonaldehyde is made by introducing aldol into a boiling aqueous solution of a salt at pH 2--7 which has a buffering action within that range, the solution being of sufficient concentration to have a dehydrating effect.  The distillate separates into crotonaldehyde and water layers; a part of the water layer may be returned to the reaction vessel to prevent separation of the salt. The reaction liquid may be continuously renewed by withdrawing a part and replacing it by fresh solution; or the withdrawn part may be purified by extraction of impurities by means of crotonaldehyde and returned. The invention is described with reference to examples of the use of primary sodium phosphate, primary and secondary sodium phosphates, potassium bifluoride and sodium acetate respectively.  In the last example, the aldol solution fed in is at pH 3,5.  Specification 370,252 is referred to.  The Specification as open to inspection under Sect. 91 includes the use of boiling solutions of an electrolyte, including water-soluble organic and inorganic salts having pH between 2 and 7 and acids of pH above 2.  It is also stated that the reaction liquor may be purified by boiling under reflux until free from crotonaldehyde, when the impurities separate as an upper layer, which is then removed.  This subject-matter does not appear in the Specification as accepted.

Patent GB-450598-A (GB)
Title: Manufacture of amino-chrysenesulphonic acids
Filed: 1934-12-17
Abstract: Aminochrysene sulphonic acids are obtained (1) by sulphonating an aminochrysene; (2) by sulphonating a nitrochrysene and reducing the product; (3) by heating the acid sulphate of an aminochrysene to a high temperature; and (4) by heating a sulphoaminochrysene, obtained by the action of chlorosulphonic acid on aminochrysene in pyridine, in a solvent.  According to examples, (1) 2 - aminochrysene is sulphonated directly with sulphuric acid monohydrate to give a monosulphonic acid, and by conversion to its sulphate, followed by heating under reduced pressure or in chloronaphthalene, to give a different product; (2) 2-nitrochrysene is sulphonated, followed by reduction of the sulphuric acid solution with iron; (3) sulphaminochrysene (obtained by the action of chlorsulphonic acid on 2-aminochrysene) is heated in chloronaphthalene to give a product probably identical with that obtained by heating the amine sulphate; (4) 2 : 8-diaminochrysene is sulphonated with monohydrate. Specification 449,182 is referred to.  The Specification as open to inspection under Sect. 91 refers also to the diazotization of aminochrysenesulphonic acids and coupling with b -naphthol to give red to violet dyes, and to the deamidizing of aminochrysene sulphonic acids followed by alkali-fusion to give hydroxychrysenes, one of which may be coupled with diazotized sulphanilic acid.  There are also examples of the sulphonation and saponification of 2 - acetaminochrysene or -benzoylaminochrysene and of amino-acetaminochrysene, which latter may be obtained by nitrating acetaminochrysene and reducing the product.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,114,071. High-voltage circuit-breakers. GENERAL ELECTRIC CO. 24 Aug., 1965 [5 Oct., 1964], No. 36224/65. Heading H1N. In a high-voltage circuit-breaker having a plurality of series-connected " breaks," each break is shunted by a variable length gap 73, 88. The length of the gap is reduced during a closing operation of the circuit-breaker so that the gap will break down at a lower voltage than will cause a flashover across any insulation parallelling the gap and so protect the insulation from damage should the breaks not close simultaneously. The circuit-breaker may be that of Specification 842,984 and have a resistor in series with auxiliary contacts 73, 76 connected across each main break. The movable contact 76 is opened against the bias of a spring 84 by a movable crosshead 81. When the closing operation is initiated, compressed gas is applied to a piston 102 which turns a latch 95 to release an electrode 88. This electrode is moved by a spring 90a into the dotted line position 89 to define the reduced gap 90. In this position further movement of the electrode is prevented by the latching head 96 abutting a fixed stop 97. Subsequent movement of the crosshead 81 permits the spring 84 to close the contacts 73, 76, the latch 95 moving with the contact 76 to a position where it relatches the head 96. In an alternative arrangement, Fig. 4 (not shown), the electrode 88 surrounds the contact 76 and is moved up to the stop 97 by the initial movement of the contact 76.
