Abstract: 884,837. Making boats; angular bending; jointing; stamping. TERRY, R. L. July 6, 1960 [June 1, 1959], No. 18621/59. Classes 83 (2) and 83 (4). At least the foot of the stem of a boat hull or bow portion is made by folding or crimping a sheet of deformable material. A sheet of metal which may be formed of two sheets riveted together is folded as shown in Fig. 3 by pressing each fold into a die or in one operation using a pair of mating dies. Subsequently the folds are completed and held between angle plates 3, 4 secured together by bolts 6, rivets or roves. Alternatively, the inner or both angle plates 3, 4 may be omitted in which case the folds may be filled with a synthetic resin or oalsum and, if desired, held by clamps. If only the foot of the stem is made in this way the sheet may be welded or riveted to form the upper part of the stem. The bilge lines are formed by panel bearing using a die, and the transom and gunwales are attached by screws. The hull may be formed from two superposed sheets with kapok or powdered cork mixed with a binder placed between the sheets. The bilge lines of the hull may be shaped by heating an aluminium alloy sheet folded as above, enclosing the upper surface of the sheet and introducing liquid under pressure into the enclosure to force the hull into a die. Alternatively the space between the die and the hull may be sealed and evacuated through an aperture in the die, so forming the bilge line by atmospheric pressure.

Filed: 1975-05-06
Abstract: 1495314 Oil-water separator HYDRONAUTICS INC 6 May 1975 [6 May 1974] 19046/75 Heading BID  An oil-water separator comprises a housing divided by a coalescing element 26 of polyurethane foam which is located between a fixed perforate wall 28 and a perforate wall 30 which is periodically advanced by ram 32 to squeeze accumulated oil out of element 26, the outer periphery of element 26 being enclosed by an impervious flexible sleeve 40, which is releasably sealed to plates 28, 30 (Fig. 2, not shown). Element 26 may comprise a plurality of chips or pads but is preferably a single block with 30-100 pores per linear inch and is bonded to sleeve 40. The block is compressed radially by sleeve 40 and by the oil-water mixture which fills annular space (50) between sleeve 40 and wall 42. Thus friction between sleeve 40 and wall 42 is avoided when the element 26 is squeezed (Fig. 3, not shown). Outlet chamber 24 contains a baffle 39 which directs coalesced oil upwards to outlet 14. An oil discharge pump connected to outlet 14 may be controlled by electric probes 41, 43, 45 which monitor the oil-water interface in chamber 24. Plate 30 could have valves to prevent oil being displaced back into chamber 22 when element 26 is squeezed, but as shown oil is squeezed into both chambers 22, 24. Water may then be recycled by pump 59 to both chambers to displace the oil towards outlets 14 and 14', the inflow of oilwater mixture being suspended during squeezing. Chamber 24 could be remote from housing 10 and connected thereto by piping.

Title: Improvements in and relating to modulation indicating or measuring means
IPC: G01R29/06
Filed: 1943-11-22
Abstract: 570,279. Measuring modulation. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 22, 1943, No. 19498. Convention date, Nov. 23, 1942. [Class 40 (v)] Modulation indicating or measuring appara. tus comprises a source of modulated carrier voltage, means for rectifying the voltage into a unidirectional voltage having an A.C. component, a second rectifying means, means for supplying the A.C. component thereto to produce a second unidirectional voltage, and means for comparing these unidirectional voltages. Modulated carrier voltage from a source such as a variable-coupling radiofrequency transformer 10 is applied across a diode 11 having a cathode 12 and anode 13 in series with a load resistance 14. A condenser 16 is connected across the resistance 14 and is charged during each positive alternation. During negative alternations no current passes through the diode and the condenser discharges through the resistance 14. The voltage across the resistance 14 contains a D.C. component proportional to the carrier wave voltage and an A.C. component representing the audio or modulating voltage. The A.C. component is applied to a second diode 18 having an anode 19 and cathode 20 and a load resistance 21. A coupling condenser 22 blocks the D.C. component of the carrier wave, and an inductance 36 blocks radio frequency currents, but passes the audio component of the voltage applied to the rectifier 18. During the positive portions of the audio voltage wave a unidirectional current passes through the load resistance 21, an iron core inductance 37 providing a return path. A condenser 38 is provided to smooth out the pulsating D.C. in the resistor 21. A D.C. voltmeter 23 is connected between the cathodes 1.2, 20 and gives a reading proportional to the percentage modulation. An ammeter 15 measures the average rectified D.C. current in the first circuit and may be marked at the standard value at which the meter 23 is calibrated, the input being adjusted to this value when taking measurements. In a modification, a doublediode is used instead of the separate diodes 11, 18 and a single meter is connected to a twoway switch so as to read either the current through the resistance 14 or the voltage across the cathodes.

Abstract: Unspecified types of dyes, dyeing with; cellulose esters or ethers, dyeing; printing.-The fastness of dyeings and particularly the fastness to the combined agencies of light and acid of dyeings, printings, or stencillings with anthraquinone derivatives containing free amino, alkylamino, or arylamino groups, is increased by incorporating in the materials, before, during, or after their colouration, one or more colourless or white bases containing one or more alkylamino groups and two aryl residues.  Specified bases are tetramethyl-or other tetralkylated diaminodiphenylmethanes, tetramethyl-or other tetralkylated diaminodiphenylethanes, tetralkylated benzidines, and tetralkylated dianisidines.  The invention is applicable to the colouration of textile or other fibrous materials, films and the like, and especially such as are made of or contain cellulose esters or ethers.  Other substances which improve the fastness, such as the urea, thiourea, and guanidine derivatives of Specification 340,572 may also be incorporated. Inorganic compounds having an alkaline reaction, e.g. sodium carbonate, borax, disodium hydrogen phosphate, sodium acetate, sodium palmitate, or potassium oleate may also be applied separately from or simultaneously with the alkylated aminodiaryl bases, preferably during colouration or during a finishing or other after-treatment. The alkylated aminodiaryl bases may be applied in solution or absorbed from aqueous solutions of their salts, e.g. the hydrochlorides, or applied as dispersions, e.g. such as are produced by the methods of Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737, and 323,788, [all in Class 2 (iii), Dyes &c.].  Compositions containing the bases together with the colouring matters, preferably in dispersed form, may be employed. In the application to artificial materials, particularly cellulose ester or ether materials, the bases may be incorporated in the spinning solutions.  The following examples are specified.  (1) A cellulose acetate knitted fabric is dyed for 1 1/2 hrs. at 75-80 DEG C. in a bath containing a turkey red oil dispersion of 1-amino-4-methylaminoanthraquinone and tetramethyl-4 : 41-diaminodiphenylmethane.
