Title: The strengthening and colouring of articles made from a reducing glass composition
IPC: C03C21/00
Filed: 1968-03-27
Abstract: 1,214,666. Strengthening and colouring reducing glass. ANCHOR HOCKING CORP. 27 March, 1968 [28 March, 1967], No. 14802/68. Heading ClM. A glass article having a composition including 45 to 80% by weight of 8i0 2  and 7 to 25% of Na 2  O and which has been made from a reduced glass composition, has a surface layer enriched in copper ions and which is under compression relatively to the remainder of the article, which imparts an increased abraded strength to the article. Reduced glasses which include 55 to 76% by weight 5i0 2 , 9 to 19% Na 2. O, 0 to 13'3  total (CaO + MgO), and 1 to 22% Al 2 O 3  are preferred. The reducing glasses are made from a batch which includes a reducing agent preferably 0-02 to 10% by weight of FeS, MoS 2 , ZnS, Fe 2 O 2  or FeO, starch and other thermally decomposable organic material. The enrichment of Cu ions in the surface layer is preferably 0-1 to 7 % Cu as measured by X-ray fluorescence. The article may be an amber bottle which after treatment changes colour to ruby, and the article then has a transmission to light of 0-3 to 0-6 micron wavelengths which is less than that of a similar article without the copper ion enriched layer. The method comprises heating the article in the presence of a vapour of at least one curpous halogen compound, e.g. CuCl, CuBr or CuI and subjecting the article to a temperature above the annealing point of the glass but below the temperature at which the glass article sags out of shape preferably 50 to 200 F. above the annealing point for such a time that when the article is cooled below its annealing point, the copper enriched surface layer is placed in compression.

Title: Improvements in and relating to the production of coal tar bases
Inventor: HOLDSWORTH ERNEST CLIFFORD
IPC: C10C1/00
Filed: 1964-04-10
Abstract: "Bases sulphate" which includes sulphates of pyridine, methyl, dimethyl and trimethyl and other substituted pyridines, quinoline and isoquinoline and homologues and other bases occurring in coal tar with b.p. up to 300 DEG  C. are converted to bases by treatment with "concentrated gas liquor" referred to as C.G.L. which is obtained by the fractionation of ammoniacal gas liquor and usually contains 15 to 25% by wt. of ammonia as sulphide and carbonate.  It is preferred to add insufficient C.G.L. to the bases sulphate to precipitate all bases to give a mixture of free bases, organic and inorganic impurity readily separable from the residual bases sulphate, the latter being separated and neutralized with further C.G.L. to yield a final bases fraction.  It is preferred to add C.G.L. in the first neutralization to obtain a basis sulphate of pH 4.3 to 5.5, and in such a way that only a minor proportion of bases is precipitated along with the organic and inorganic impurities and the resulting sludge is either discarded or first treated with fresh bases sulphate, to recover its bases content.

Title: Improvements in or relating to radio direction finding systems
IPC: G01S1/02
Filed: 1932-05-25
Abstract: 402,122. Directive wireless signalling; television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, DOWSETT, H. M., 47, Drayton Gardens, Winchmore Hill, both in London, and KEMP, R. J., Gurnigoe, Goldlay Avenue, Chelmsford. May 25, 1932, No. 14879. [Classes 40 (iii) and 40 (v).] Relates to receiving systems for use with direction finding systems in which a television image is transmitted which upon reception indicates the direction of the transmitter as described in Specifications 402,121 and 402,443. The receiving station comprises a directional aerial A and a non-directional aerial B the picture signals derived therefrom superimposed out of phase on the picture constituting lamp N.L. The phase opposition is introduced by providing an anode bend detector V2 for the signals from aerial A and a leaky grid detector V4 for the signals from the aerial B their outputs being superimposed on the amplifying system V3, V6, V7 feeding the lamp NL. The valve V4 also feeds an amplifier V8, V9 for selecting the synchronising signals which are of greater amplitude than the picture signals and are able to break down a neon tube GL in the output circuit of the valve V8. The phase opposition may be produced in other ways, for example the amplifiers of the signals from the two aerials may differ in the number of valve stages. The directional system may comprise a Bellini-Tosi aerial system and radiogoniometer the " vertical effect " of said aerial system being utilized for non-directional reception. The amplitude of the non-directional signals is adjusted to be approximately the same as that from the directional system when the latter is say within 10‹ of the correct bearing, so that a clear positive picture is obtained when the directional system is correctly oriented which is in sharp contrast to the picture obtained at other settings.

Title: Apparatus for controlling a variable of moving elongate material
IPC: H02P7/34
Filed: 1965-04-08
Abstract: 1,083,152. Automatic tension control. WESTINGHOUSE ELECTRIC CORPORATION. April 8, 1965 [April 30, 1964], No.14940/65. Heading G3R. In a system in which elongate material is transported by an electric motor drive, deviations of a variable of the material from a desired value are automatically corrected by applying an error signal to adjust motor speed through three controllers in cascade, each of the controllers introducing an integral component, and the second and third controllers respectively introducing components dependent on motor speed and current. As described, paper strip passing between two pairs of driven pressure rolls forces a jockey roller against a spring to operate a potentiometer which thus produces a voltage dependent on the tension of the strip. This voltage is compared with an adjustable voltage, representing the desired tension, and any difference applied through three chopper-type amplifier-modifiers in cascade to control a phase-controlled semi-conductor rectifier energizing either the field circuit of a Ward Leonard set driving the second set of rolls or the armature of a D. C. motor driving the rolls so that tension is restored to the desired value. The amplifier-modifiers are provided with resistance-capacity networks to introduce integral or integral and differential components of control, with or without filtering, and are also provided with biased diode limiters. A signal dependent on the speed of the controlled rolls is derived from a tachometer generator and the difference between this signal and an adjustable reference signal applied as negative feedback to the input of the second amplifier-modifier. A signal dependent on the armature current of the controlled motor is derived from a series resistor and the difference between this signal and an adjustable reference signal applied as negative feedback through a magnetic amplifier to the input of the third amplifier-modifier.
