Title: An improved protective device for high tension networks provided with earthing coils
IPC: H02H9/08
Filed: 1925-03-10
Abstract: 230,503. Akt.-Ges. Brown, Boveri, et Cie. March 10, 1924, [Convention date]. Cut-out arrangements.-In protective devices for high tension networks having earthing coils D, or D1, D2, the coils are normally combined with auxiliary resistances, either an ohmic resistance W, or a spark gap F so that the resultant resistance is either very high or very low, but these auxiliary resistances are automatically cut out by a current or voltage relay R when a leak to earth occurs. In the form shown in Fig. 4, the switch closes on earth leak to short-circuit the spark gap. The spark gap has a disruptive discharge voltage less than that of the network. The Specification as open to inspection under Sect, 91 (3) (a) describes also an arrangement shown in Fig. 5 (Cancelled), in which on the occurrence of a fault the resistance of the neutral point to earth is increased by the automatic opening of the switch S, which, together with the ohmic resistance W, is connected across the earthing coil. This subject-matter does not appear in the Specification as accepted.

Title: A process for the production of pseudoionones or homologues of pseudoionones
Filed: 1956-03-02
Abstract: Mixtures of stereoisomeric pseudoionones or of homologues of such stereoisomers are prepared by heating a mixture of dehydrolinolool and an excess on a molar basis of an acetoacetic ester having the general formula <FORM:0802534/IV (b)/1> wherein R1, R2, R3 and R4 may be hydrogen or alkyl or alkenyl groups and R is the radical of a primary or secondary alcohol ROH possessing a lower B.P. than that of dehydrolinalool, such as methyl, ethyl, isopropyl or benzyl alcohol, the heating being effected at a temperature from 160 DEG  to 180 DEG C. sufficiently high to produce a reaction comprising simultaneously the alcoholysis of the ester and the intramolecular rearrangement accompanied by decarboxylation of the ester resulting from the alcoholysis, and thereafter isolating the resulting pseudoionones or homologues thereof as an isomeric mixture by distillation of the reaction product.  The recovered mixtures may be cyclized to the corresponding ionones by treatment with BF3 according to the method of Specification 666,881. In examples: (1) dehydrolinalool is heated with 3 mols. of ethyl aceto acetate at 160 DEG  C. with stirring for 36 hours during which ethanol and CO2 distil off as formed and the product is fractionated under reduced pressure; the pseudo-ionones recovered are cyclized to give a -ionones and some b -ionones; (2) ethyl a -methyl aceto acetate is reacted similarly at 180 DEG  C., yielding stereoisomeric 9-methyl pseudo-ionones which are cyclized to 22-methylionones; (3) ethyl propionyl acetate is reacted as in (1) yielding the 11-methyl pseudo ionones which are cyclized to 24-methyl-ionones.  Specifications 646,962, 733,884, 741,047, and 762,656, also U.S.A.  Specification 2,167,168, are referred to.

Title: Process of and apparatus for the production of nitric acid
IPC: C01B21/26
Filed: 1947-03-11
Abstract: <PICT:0636951/III/1> In producing nitric acid from gases containing nitrogen oxides and free oxygen by absorbing nitrogen dioxide in water, the absorption is carried out successively in two or more stages by introducing the water at different points of the absorption process, removing the nitric acid formed from each absorption stage, passing the nitric oxide formed and unabsorbed at each absorption stage to the next and allowing the unabsorbed nitric oxide to oxidize to nitrogen dioxide by reaction with the free oxygen present prior to or upon reaching the next absorption stage.  The oxidation of the nitric oxide may be assisted by the presence of dilute nitric acid, preferably of a concentration between 50 and 57 per cent by weight. According to one embodiment, the gases enter through inlet 2 into the first, b1, of a series of absorption zones of a tower 1 wherein the nitrogen dioxide content of the gases is converted by absorption in water admitted through conduits into nitric acid which is drawn off through conduit e1.  The unabsorbed gases then flow upwardly through a demisting zone c1 wherein a substantial portion of the residual nitric oxide is converted into nitrogen dioxide, the water separated in the zone issues through conduit f1 as dilute nitric acid. The demisted and partially oxidized gases then enter an oxidizing zone d1 in which they are sprayed with nitric acid which issues from the tower through conduit g1.  The treated gases enter further absorption stages b2 . . . b5 and the series of operations is repeated until the last stage when the residual gases after being demisted are vented at outlet 3.  In another embodiment, Fig. 2 (not shown), substantial oxidation of nitric oxide takes place in each demisting zone, while further oxidation proceeds in the lower part of each adsorption zone. Specification 131,029, [Class 1 (ii)], is referred to.

Abstract: 1,098,196. Digital position control circuits. ADREMA Ltd. May 23, 1966 [Feb. 22, 1965], No. 7474/65. Heading G4H. In apparatus for controlling the position of a movable object, a multidigit signal represents the desired position and another multi-digit signal is derived representing the actual position, corresponding digits are compared to develop first and second difference signals of opposite polarity representing the amount and direction of the difference, a tachogenerator gives a signal representing by magnitude and polarity the speed and direction of a shaft controlling the movable object, and there are means for combining this signal with the difference signals to form a first control signal representing by its magnitude the required acceleration of the object and other control signals representing the required direction of the acceleration, and means for applying these signals to the motor controlling the position of the object. The apparatus may be for positioning the type drum of an embossing machine. This is carried on a shaft with a coded cylinder which is sensed photoelectrically to provide a seven-bit signal representing the position of the type drum. A row of smaller holes on the coded drum gives synchronizing signals. The comparator 30 gives a zero output for identity, a positive output for each 0, 1 comparison and a negative output for each 1, 0 comparison. These signals are summed according to their weights at positive and negative output points, and applied to a differential amplifier 31 with a signal from a tachogenerator proportional to shaft velocity. Alternatively the speed signal may be derived from the back e.m.f. of the motor 11. The direction of the required acceleration is indicated by the respective polarities of the outputs of the differential amplifiers and a bistable circuit 40 is set in correspondence. This controls a bistable circuit 43 controlling the reversing circuit 44 of the motor. Delay circuits 41, 42 inhibit amplifier 32 to prevent excitation of the motor while the reversing circuit is being changed.
