Title: The self-excitation of alternators
IPC: H02P9/38
Filed: 1965-05-14
Abstract: 1,104,781. Alternators. SIEMENS-SCHUCKERTWERKE A.G. 14 May, 1965 [14 May, 1964], No. 20603/65. Heading H2A. [Also in Division G3] A self-excited alternator 1 has a field winding 11, output terminals R, S, T, Mp, and an excitation circuit which includes rectifiers 21, 22 and a regulator 3, and which has a threshold value of applied voltage below which the circuit cannot pass current to initiate selfexcitation of the alternator. When the alternator is first started-up the output voltage may not read this threshold value, owing to insufficient residual field magnetism for example, and to obviate this effect thyristors 41, 42 are connected as shown in parallel with the excitation circuit. Firing signals for the thyristors are derived from the alternator output by way of a control circuit including step-up transformers 65, 66, rectifiers 61 to 64, a signal-limiting non-linear resistor 53 and diodes 51, 52, the control circuit also including a zero diode 55 and a further thyristor 50. When the alternator output voltage is below the said threshold value, the control circuit produces firing signals to render thyristors 41, 42 conductive, whereby the normal excitation circuit is by-passed and the field winding 11 is energized with pulsating direct current derived from the output terminals R, S by way of the thyristors 41, 42. The output voltage can thus build-up until the threshold value is reached; at this value, Zener diode 55 conducts to render thyristor 50 conductive, thus removing the firing signals from thyristors 41, 42 and rendering them non-conductive, the normal excitation circuit then being effective to energize the field winding 11.

Title: Improvements in or relating to the raising and salving of ships and other sunken objects
IPC: B63C7/12
Filed: 1924-09-04
Abstract: 243,802. Kiwull, W. Sept. 4, 1924. Sunken ships and objects, raising.-In the salvage of sunken ships and other objects by methods involving the artificial formation of ice over rents, hatchways &c. which require to be closed preparatory to pumping out the water, the ice formation is facilitated hy maintaining the same body of water in contact with the freezing surface until freezing occurs. For this purpose the pipes through which the cooling medium is circulated may be' surrounded with fibrous material such as wood wool or filamentary metal, or with slime or mud. Alternatively, the pressure occasioned by directing a stream of water from a pump or other means against the cooling surface may be used. Owing to the convection currents set up by the change in density of water in cooling from 4‹ C. to freezing point, the formation of ice 2 on a pipe 1, Fig. 1, through which cooling medium is circulated is irregular as shown. If the pipe be surrounded by fibrous material 4, Fig. 2, the convection currents are broken up, and the ice 2 is formed regularly round the pipe. In the method illustrated in Fig. 5, refrigerating apparatus 10 is sunk by means of cables 14 and supplied with cooling liquid through the pipe 15. From the apparatus 10 extend flexible pipes 13, which may have corrugated surfaces or may be of fabric so as to ensure the regular formation of ice. These pipes are placed in position by divers so that a substantially uniform layer of ice is formed over the opening in the hull of the wreck. A system of pipes 21, Fig. 9, covered with wood wool, filamentary metal or suitable fibre may be used in the form of a mat placed over the opening which it is desired to close, the material retaining the water until it freezes into an ice layer 22. Ordinary collision mats 20, Fig. 8, may be used by providing flexible pipes 21 for the cooling medium in place of the usual hawser ropes. The mat 20 may be itself used as a freezing element by making it of double fabric closed at the edges and introducing the cooling medium through the pipe 21 between the two layers. The ice foundation may be localised by the provision of heat insulating layers 24. Specifications 183,536, 219,011, and 240,361 are referred to.

Abstract: 890,501. Electrical measuring systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 28, 1958 [July 3, 1957], No. 21053/57. Class 40 (1). The angular acceleration of a shaft SH is determined by comparing its speed with that of a flywheel FW coupled to the shaft SH via a pair of selsyns MS1, MS2. The selsyn MS2 is of the differential type, the three rotor windings being connected to the stator windings of a third selsyn MS3 having resilient coupling between rotor and stator and carrying a pointer IM movable over a scale calibrated in terms of acceleration. According to the Provisional Specification, the flywheel rotates in synchronism with the tested shaft when the latter is turning at a constant speed. During acceleration, the lag between the rotor of MS2 and the rotating field results in a torque which deflects the pointer against a constraining spring.  Modifications.-The Provisional Specification describes two systems in which the differential selsyn MS2 is omitted. In one system, the " stator " of MS1 is free to rotate and carries the flywheel. In the other system, the " stator " of MS3 is free to rotate and carries the flywheel. continuous rotation of the "rotor" being prevented by a constraining spring.

Title: Improvements in or relating to isoprene derivatives of trimethyl cyclohexene
IPC: C07C47/38
Filed: 1960-06-16
Abstract: The three aldehydes P-(Is)n-CHO where P represents the 2,6,6-trimethyl-cyclohexene-1-yl group, Is is the isoprene residue <FORM:0935006/IV(a)/1> and n is 1, 2 or 3, are produced by a series of reactions starting from the appropriate methyl ketone P-(Is)n-1-CH=CH-CO-CH3 which is condensed with an alkyl formate, in the presence of a catalyst such as a metal alcoholate, to give a salt of the beta-ketoenol P-(Is)n-1-CH=CH-CO-CH=CHOH (II) Compound II is converted into the acetal of the tautomeric beta-keto-aldehyde form <FORM:0935006/IV(a)/2> where R2 and R3 are lower alkyl groups, which is treated with methyl lithium or a methyl magnesium halide or a methyl zinc halide to obtain <FORM:0935006/IV(a)/3> and this compound VI is then dehydrated and hydrolysed in order to obtain the required aldehyde P-(Is)n-CHO.  The starting ketone is beta-ionone for the preparation of beta-ionylidene-acetaldehyde; and the C18 ketone (n=2) is the starting ketone for the preparation of retinene.  The C18 ketone can be obtained by condensing beta-ionylidene-acetaldehyde with acetone in the presence of an alkali metal alcoholate or an alkali metal hydroxide.  Similarly the C23 ketone, required for the preparation of the C25 aldehyde, is obtained by condensing retinene with acetone.  The C18 and C23 ketones may be purified by molecular distillation, chromatography, or by the formation of the cyanacethydrazone.  The beta-keto-enol II, or its sodium salt, may be converted into the acetal V by raacting it with a lower alcohol containing a small amount of dissolved hydrogen chloride and a formate, or acetate, of the alcohol. Alternatively, the enol or its sodium salt is first acylated (e.g. with acetyl chloride or acetic anhydride) or etherified (e.g. with methyl sulphate before treatment with the alcohol.  The dehydration and hydrolysis of compound VI to obtain P-(Is)n-CHO may be carried out in one stage by the action of aqueous hydrochloric acid on a solution of compound VI in acetone; alternatively the compound VI may first be dehydrated by means of a trace of acid or an alcoholic solution of the compound, and the dehydration-product is then hydrolysed with aqueous hydrochloric acid in acetone.
