Title: Improvements in or relating to rectified power equipment
IPC: B60L9/12
Filed: 1951-12-21
Abstract: 696,348. Rectifying; transformers. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 21, 1951 .[Jan. 26, 1951], No. 29944/51. Class 38 (ii). [Also in Groups XXXVII and XXXIX] The invention relates to a method of reducing the interference with a communication system by harmonics in the A.C. overhead line of a tractions system, the vehicles of which are driven by D.C. motors energized through rectifiers on the vehicle. Each of the motors, which are divided into two groups A 1 , A 2  and A 3 , A 4  is connected to its own pair of rectifiers 41, 42, which may be ignitrons, with which are associated coupled commutating induct. ances. The rectifiers are connected to taps T1-T14 on the secondary winding 35 of the supply transformer, the primary winding 34 of which is supplied through collector 33 from a single phase overhead line 30, harmonics in which may induce interference in a nearby communication system. The actual connections are made through switches A-N, A<SP>1</SP>-N<SP>1</SP>, a-n, a<SP>1</SP>-n<SP>1</SP> which are operated by a controller in the sequence shown diagrammatically in the Figure, to vary the tap connections and thereby the speed of the motors. Circulating current suppressor coils P1-P4 are provided. As the controller is operated the rectifiers are so connected to the taps in sequence that each pair has equal and unequal voltages applied to it in turn, and when the voltages applied to the rectifiers of one group of motors are unequal, the voltages applied to the rectifiers of the other group are unequal to the same extent, but the greater voltages are respectively derived from opposite sides of the centre tap. Thus, with the controller in notch 6, switches B, B<SP>1</SP>, b, b<SP>1</SP>, C, C<SP>1</SP>, C, C<SP>1</SP> are closed, rectifiers 41, 42 of the motor group A1, A2 are connected through lines L2, L1 to taps T1, T4 unequally spaced from centre tap X, and rectifiers 41, 42 of the motor group A3, A4 are connected through lines L4, L3 to taps T3, T2 which are unequally spaced from the centre tap X by a similar amount but on opposite sides. In this way the arrangements, such as those described in Specifications 682,610 and 682,650 to suppress harmonic interference are unaffected by the unbalance condition of the rectifiers of each pair, while avoiding the need for doubling the number of taps to allow the same number of effective controller steps without producing unbalance.

IPC: A61K35/54
Filed: 1928-10-19
Abstract: 299,060. Soc. of Chemical Industry in Basle. Oct, 20, 1927, [Convention date]. Medicines for internal use.-Water-soluble and lipoid-soluble hormones are obtained separately from sexual glands by hydrolysing the glands by means of chemicals or ferments, extracting the product with a water-insoluble solvent, separating the solution of the lipoid-soluble hormone so obtained, and recovering the water-soluble hormone from the aqueous fraction, or its dry residue, in the usual manner. According to an example, bull testicles are hydrolysed with 20 per cent sulphuric acid and the product extracted with ether. 'The aqueous residue is neutralized with milk of lime, filtered, and evaporated to dryness in a vacuum. The. water-soluble hormone forming the residue may be purified by a re-solution in water and precipitation by a lead or mercury salt or phosphotungstic acid, or by extraction with alcohol. The etheral extract may be evaporated to dryness and further purified by extraction with alkali, or bv the process described in Specifications 113,311 and 226,372. According to a second example ovaries are ground with dilute sodium carbonate solution, subjected to tryptic digestion, and the resultant liquid extracted with ether, neutralized with sulphuric acid and evaporated to dryness. The two products are purified as in the previous example. According to a third example minced ovaries are heated with alcoholic potash, concentrated, diluted with and extracted with ether. The aqueous residue is worked up as before and the ethereal solution is washed successively with water, dilute acid, and water, and is dried and evaporated. The residue may be used directly or further purified.

Patent GB-953156-A (GB)
Title: Improvements in or relating to the recovery of phosphoric acid by solvent extraction
IPC: C01B25/22
Filed: 1962-08-08
Abstract: Phosphoric acid is recovered from the aqueous reaction mixtures produced by the decomposition of tricalcium phosphate with hydrochloric acid in an aqueous reaction system by solvent extraction using an amide of one of the following general formulae <FORM:0953156/C1/1> in which R1, R5, R6, R7 and R8 are hydrogen or a hydrocarbon radical; R2 and R3 are hydrogen or a hydrocarbon radical, or R2 and R3 together with the nitrogen to which they are attached form a heterocyclic ring system; R4 is a hydrocarbon radical and R9 is a divalent hydrocarbon radical.  The extractant solvent may contain more than one of these amides and/or another organic solvent miscible with the amide and which lowers its viscosity.  To recover the phosphoric acid from the solvent extract a water immiscible organic solvent may be added and any hydrochloric acid removed from the phosphoric acid in the aqueous layer thus produced. Alternatively the solvent extract may be re-extracted with water and again removing hydrochloric acid from the aqueous solution of phosphoric acid.  If desired, the solvent extract may be directly subjected to a thermal treatment, e.g. distilling or stripping to remove the solvent amide and hydrochloric acid from the phosphoric acid.  The extraction of the decomposition liquor by the amide is preferably effected at a temperature at which the solubility of phosphoric acid in the amide is comparatively high and then after separation from the aqueous liquor, the temperature is lowered to reduce the solubility. Numerous examples are given.

Title: Improvements in and relating to linear motion transmitting apparatus
IPC: G08C19/42
Filed: 1946-10-12
Abstract: 630,443. Electric indicating systems. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 12, 1946, No. 30470. Convention date, Oct. 12, 1945. [Class 40 (i)] The transmitter or receiver in a saturable core telemetering system as disclosed in U.S.A. Specification 2,342,637 is replaced by an equivalent magnetic arrangement of a row of magnets alternating in polarity movable linearly past the poles of three saturable cores energized by A.C. windings connected to the other end of the system. As shown, the magnetic equivalent of the saturable core rotary transmitter arrangement of Fig. 1 is obtained by mounting the saturable cores 12, 13, 14, Fig. 3, in line with their air-gaps 18, each adapted to co-operate with three permanent magnets 19, 20, 21-22, 23, 24-25, 26, 27, mounted radially on a bar member 28 movable linearly by the pressure-sensitive bellows 28a or other variable. As described with respect to Fig. 2 (not shown), one complete rotation of the rotor 11, Fig. 1, corresponds to a linear movement of the bar 28 equal to twice the spacing of the adjacent magnets 19, 20, 21 etc. in any one trio. As shown in Fig. 4, all the permanent magnets 19 ... 27 &c. may be equally spaced to cater for substantially unlimited linear movement of the member 28. In this case, the receiver 30 which is connected in three-phase delta fashion to the transmitter coils 15, 16, 17 has an additional pointer geared thereto, Fig. 5 (not shown), to indicate the number of revolutions thereof. The conversion from linear to rotary motion preferably follows a linear law, but by suitably shaping and spacing the core polepieces or the transmitter magnets or adding further magnets to a support 28, other laws may be obtained. Each magnet trio, Fig. 6, may be built up of axial magnets 43, 44 and disc-shaped pole-pieces 40, 41, 42, the three saturable cores being spaced circumferentially around the axially-movable magnets; Fig. 7 (not shown), and axially spaced as shown, the gaps 18 of the cores 12a, 13a, 14a co-operating with one magnet trio rather than as shown in Fig. 4, thereby economizing in space and material. The system of Fig. 4 is reversible, i.e. the rotary receiver 30 may function as a transmitter &c. A plurality of receivers may be operated from one transmitter.
