Abstract: 703,267. Gas turbine plant. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 19, 1951 [Oct. 19, 1950], No. 25541/50. Class 110 (3) A gas turbine plant fuel system has a fuel delivery control member connected to an actuating member by a trippable connection comprising an electromagnetic device having an excitation coil which when energized allows the actuating member to move the control member to increase the fuel delivery against a bias urging the control member to the off position and a control circuit for the coil arranged to be de-energized when protective means operated in response to an operating condition of the turbine, is actuated The fuel delivery valve 1 has an inlet union 2, a main fuel outlet union 3 and an idling outlet union 4. The valve member 5 is biased to close the connection between the inlet and outlet unions 2, 3 by a spring 6. Passages are provided in the valve 1 so that when the member 5 is closed the connection between, the unions 2 and 4 is still open so that the turbine will continue to run at idling speed. The member 5 is of magnetic material and extends together with an actuating member 9 into the bore of excitation coil 8. The ends of the members 5 and 9 are separated from one another by a non-magnetic washer 13. The actuating member 9 is connected through a slipping clutch 19 with an electric servomotor 17 which forms part of any desired control system such as the control systems described in Specifications 703,263, 703,264, 703,265 and 703,266, [all in Group XXXV]. The coil 8 is connected to, an energizing circuit including normally closed contacts of one or more protective relays responsive to turbine overspeed excessive temperature or overload. When the coil is de-energized the servomotor 17 should, be energized to move the actuating member 9 to the closed position. A modification is. described in which the control and actuating members are connected by a floating lever having a further point connected to one of the members 5 or 9 whereby the point provides a reaction for tne floating lever when the coil 8 is energized. Specification 703,268, [Group XXXVII], also is referred to.
Patent GB-937779-A (GB)
Title: Improvements in or relating to telescopic blowing tubes for metallurgical furnaces
IPC: C21C5/46
Filed: 1961-07-14
Abstract: 937,779. Telescopic oxygen lances. GUTEHOFFNUNGSHUTTE STERKRADE A.G. July 14, 1961 [Sept. 24, 1960], No. 25623/61. Classes 51 (1) and 51 (2). [Also in Group XXVIII] A telescopic blowing tube, particularly for a converter, comprises an inlet section 1 and an outlet section 2, means for extending and retracting the sections sufficiently to introduce the tube into and withdraw it from the converter and means for moving the tube as a whole when the sections are extended to provide adjustments during a blowing process. In the preferred embodiment the inlet section 1 is provided with an end portion 9 of increased diameter which engages an annular seal 7 mounted in the outlet section 2. As the sections are retracted, the seal 7, after moving past the portion 9, does not engage the inlet section due to its reduced diameter thus avoiding any abrasive action. Guide rings 10,11 on the inlet and outlet sections, respectively, prevent lateral movement of the sections with respect to each other. Air or oxygen with or without entrained powdered materials is supplied to the section 1 from a stationary feed-pipe 15, via a pipe 16 provided with ball-and-socket joints 17, and a pipe 14, movement of the latter being guided by rollers 18. The pipe 14 and the blowing tube are supported by a rope 19 passing over a pulley 20 to a counterweight 21 which balances the inlet section 1 and pipes 14 and 16. A winch 12 is connected by a rope 13 to the top of the outlet section 2 so that by provision of the counterweight 21 the winch load is restricted to the outlet section 2. During furnace operation movement of the blowing tube is restricted to the height h, the tube being guided by a device 6, but when the tube is withdrawn it is raised through a larger distance H when an extension 23 on pipe 14 engages a retaining device or stop 22, thus preventing further movement of the inlet section 1. Further operation of the winch 22 then draws the outlet section 2 over the inlet section 1 until the blowing tube is clear of the converter 3. The seal 7 may alternatively be mounted on the inlet section 1 and engage a restricted portion of the outlet section and may be of pneumatic type which can be deflated when the blowing tube is not fully extended. The blowing tube may be disposed other than vertically according to the type of converter employed.

Title: Shadow masks for use in cathode ray tubes
IPC: H01J31/20
Filed: 1970-05-29
Abstract: 1316624 Colour television tubes SONY CORP 29 May 1970 [31 May 1969] 25994/70 Heading H1D A shadow mask for a colour television tube using three co-planar electron beams, wherein the apertures in the mask are arranged at the intersections of barrel-shaped horizontal lines with orthogonal pin-cushion-shaped vertical lines as in Specification 1,249,954 is characterized in that the apertures are circular in the centre of the mask and elliptical away from the centre. When the mask and the screen are spheres of radius R disposed a distance L from the centre of deflection of the beams, it is shown that the horizontal and vertical pitches P H (n, m) and P V (n, m) at co-ordinates (n, m) measured from the centre should be related by the equation if the pitches are to be constant along the central axes. For close packing of the impact areas on the screen without any overlapping, the ratio of the major axis a(n, m) to the minor axis b(n, m) of the elliptical aperture should be related by the equation Thus apertures at the same distance from the centre have the same eccentricity but the inclination of their major axes with the horizontal varies. An alternative arrangement considered is where the pitch of the apertures is constant along a line y =γx; the horizontal and vertical pitches are then given by the equations and the axis ratio given above is multiplied by a factor Similar equations may be derived for a cylindrical mask used with a cylindrical screen.

Title: A method of and apparatus for recording
IPC: G01D15/14
Filed: 1927-10-03
Abstract: 278,389. Kirchberg, W. Oct. 3, 1927. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 3, 1927]. Photographic recorders.-A method of and apparatus for recording variations of two or more variables consists in means for producing a record of one quantity in the form of a band diagram produced by rays of light on a constantly moving record-strip amd means for optically shading the area of the band in according with variations in the other quantity. As shown in Figs. 1 and 2 applied to instruments for measuring the volume and temperature of a gas conveyed through a pipe, the spindle of the flow-meter pointer a carries a pulley b around which passes an endless belt b<2> supported by a second pulley b<1>. To the opposite runs of the belt are attached clamps c, c<1>, d, d<1> carrying screens e, e<1> supported on rollers c<2>, d<2>. Movement of the pointer a causes the screens to expose a greater or lesser amount of an elongated slot f<2> in a plate f arranged between the screens and an optically sensitive record-strip g driven by clockwork. The exposed part of the strip is acted upon by light rays from the filament of a lamp h electrically connected to the pointer i of a thermometric device and a constant voltage supply. Variations in temperature regulate the amount of resistance k in the circuit to control the current and illumination of the filament thereby varying the shading of the record produced. In a modification, Fig. 3, as applied to the measurement of the flow of gases, variations in level of a float q due to changes in pressure control the position of a translucent plate u with different degrees of translucidity from top to bottom, and a rotatable screen p controlled by a float n, in accordance with the rate of flow of the gas, is adapted to regulate the extent of an elongated slot illuminated by a lamp h<4> with constant current supply. The screen p is formed as a logarithmic spiral to render the diagram more easily readable. Several instruments for recording changes in a power plant may be employed in combination with a single record strip.

Patent GB-599046-A (GB)
Title: Process for producing dl-tryptophane and related indole derivatives
Filed: 1945-10-10
Abstract: dl-Tryptophane is manufactured from indole derivatives having a b -substituent of the formula <FORM:0599046/IV/1> (wherein each R3 represents an alkyl, aryl or aralkyl radical, R4 represents hydrogen or aryl and R5 aryl or R4 and R5, together represent the divalent radical of a dicarboxylic acid) by heating in dilute aqueous alkali and acidifying to form the corresponding dicarboxylic acid, heating thus with water to form the corresponding monocarboxylic acid, deacylating this by heating in aqueous alkali, and acidifying to precipitate dl-tryptophane.  The starting materials may be made by a preliminary condensation of an indole derivative having a b -substituent of the formula <FORM:0599046/IV/2> (wherein R, R1 and R2 represent alkyl, aryl or aralkyl groups and X represents halogen) with a malonic acid ester derivative of the formula <FORM:0599046/IV/3> (wherein R3, R4 and R5 are as defined abov and M represents an alkali metal).  In examples: (1) ethyl acetamidomalonate and dioxane are agitated and heated with a suspensing of sodium in xylene and the mixture is stirred and heated with 3-dimethylaminoindole methiodide to produce ethyl a -acetamido-a -carbethoxy-b -(3-indole)-propionate, which is refluxed with dilute sodium hydroxide solution and the product acidified with hydrochloric acid to liberate a -acetanido-a -carboxy-b -(3-indole)-propionic acid, this being refluxed with water, the resulting N-acetyltryptophane refluxed with a stronger solution of sodium hydroxide and the product acidified with acetic acid to liberate l-tryptophane; (2) ethyl phthalimidomalonate is agitated and heated with powdered sodium in N-butyl ether and the mixture is agitated and heated with 3-dimethylaminoindole methiodide to yield ethyl a -phthalimido-a -carbethoxy-b -(3-indole)-propionate, which is treated as in (1); (3) the first stage of (1) is carried out by refluxing the ethyl acetamidomalonate with a solution of sodium in ethanol and refluxing the resulting solution with the methiodide; (4) and (5) the processes of (1) and (2) respectively are carried out in an atmosphere of nitrogen, thereby increasing the yield. The methiodide in these examples may be replaced by other quaternary substituted b -(aminomethyl)-indole compounds, e.g. b -(diethylaminomethyl)-indole ethiodide or b -(diphenyl-or dibenzyl-aminomethyl)-indole methiodide, and the ethyl acetamido- or phthalimidomalonate by the corresponding methyl, phenyl or benzyl esters or by the corresponding esters of other monoacyl- or diacyl-amidomalonic acids such as formamido- or benzamidomalonic acid.  The Specification as open to inspection under Sect. 91 comprises also the use in the preliminary condensation of indole derivatives containing as a b -substituent a quaternary substituted 3-aminomethyl group of the general formula given above in which R1 and R2, together form part of a N-heterocyclic, e.g. piperidyl, radical.  This subject-matter does not appear in the Specification as accepted.
