Abstract: 431,766. Making electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Rankin, W. K. ; 267, Highland Avenue, and Hayward, C. de W. ; 59, East Plumstead Avenue, both in Lansdowne, Pennsylvania, U.S.A.) Oct. 11, 1933, No. 28084. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 13, 1934]. [Class 39 (ii)] In sealing an exhausting-tube into a glass envelope, such as an electric lamp bulb, which is subsequently evacuated, the exhausting-tube 5, Fig. 2, is placed within the open end of the bulb which is then subjected to heat and pressure to form a press seal. To prevent collapse of the wall of the exhausting-tube an internal support is provided, which may be removed after the tube has cooled down. The support may comprise a helically coiled wire 6, of a metal, such as nickel, having a coefficient of expansion equal to, or greater than, that of glass. Leading-in wires 2 may be disposed within the open end of the bulb 1 and sealed in position during the pressing operation, the completed press seal 4, prior to the removal of the coil 6, being shown in Fig. 3. In a modification a tube of nickel, which is left in position within the exhausting-tube, is used instead of the removable helical coil. In a further modification a mandril 8, Fig. 5, is inserted within the tube 5 to prevent its collapse during the forming of the pinch. The mandril is preferably tapered slightly to facilitate its withdrawal, and has a thin coating of graphite which is covered by a thin layer of copper applied electrolytically, the copper thus being held within the tube 5 when the mandril is separated therefrom at the graphite layer.

Title: Means for launching beams of ultrasonic radiation in a medium
Inventor: BRADFIELD GEOFFREY
IPC: G10K11/32
Filed: 1950-11-17
Abstract: 703,480. Ultrasonic couplings ; piezoelectric transducers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 16, 1951 [Nov. 17, 1950], No. 28227/50. Class 40 (4) [Also in Group XXXVIII] In an ultrasonic flaw detector the means for launching a beam of ultrasonic waves into the work piece comprises a linear array of one set of electro-mechanical transducer elements producing predominantly shear vibrations interspaced with another set of transducer elements producing compressional and possibly shear vibrations, the spacing of the two sets of transducers being different. As shown in Fig. 3 the shear transducers are arranged in pairs a b, d c, and g h, the spacing between the pairs being four times the spacing d between the members of a pair and the other transducers c and fare located in the gaps between the pairs. For a mild steel work piece with d = 0.73 mm. and an excitation frequency of 2.5 Mc/s the shear transducers produce a beam OA, Fig. 4, at 25 degrees to the boundary when a, d and g are excited in anti-phase with b, e and h, and when the other transducers c and f are excited in anti-phase they produce a compressional wave OB and a shear wave OC at angles of 66 degrees and 77 degrees respectively. Due to the gaps in the array a, b, d, e, g, h, a spurious beam at 64 degrees is produced which will be weaker if the shear elements are quartz crystals cut with the XY plane parallel to the boundary of the medium and the X direction normal to the plane of the diagram. When shear crystals are used with the Y direction normal to the boundary and the X direction normal to the plane of the diagram they may be excited with adjacent elements in anti-phase or with two adjacent elements in one phase and the next two elements in the opposite phase. In the latter case both shear and weaker compressional waves will be produced which are propagated in the same direction as the waves generated by the compressional elements c, f, the intensity of the compressional waves being further reduced by suitable choice of the widths of the crystals. The direction of the beam may be varied by varying the excitation frequency and the spacing between the elements may be increased if a coupling material, e.g. magnesium or sintered alumina, is interposed between the array and the work piece such that the wave velocity is greater in the coupling material than in the work piece. Beams corresponding to A, B, C, Fig. 4, will also occur on the other side of the normal and these may be prevented from reaching the work piece by using a coupling as shown in Figs. 5 and 6 in which the unwanted beam Q is propagated into a portion 7 of the coupling having roughened surfaces so that the unwanted beam is scattered and dissipated therein. In Fig. 6 the portion 4 of the coupling is shaped to concentrate the wanted beam, the surface 8 being conical with its axis along the boundary of the work piece and its apex at the point 10. Specification 664,763, [Group XXXVIII], is referred to.

Filed: 1926-11-10
Abstract: 290,309. White, G. N., Beckett, E. G., Thomas, J., and Scottish Dyes, Ltd. Nov. 10, 1926. Cements, Portland and Roman, treating after manufacture; concretes and mortars, cement ; stone, colouring; cement and concrete surfaces, hardening and preserving.-To prevent lime incrustation on cement and concrete and to improve the setting properties, commercial ammonium carbonate is added in such quantities that the amount available for combination with the lime is equal to at least 5 per cent of the weight of the cement. In the case of cement washes the amount may be from 25 per cent to 50 per cent. In the case of concretes, the ammonium carbonate may be mixed in the dry state with the dry cement, with the aggregate or with both; it may be added to the gauging water; or a saturated solution of ammonium carbonate may be applied to the surface of the concrete after it has set. The cement may be coloured by the use of vat dyestuffs in the form of paste, for instance Caledon jade green, Caledon brilliant purple RR, Caledon red BN, Caledon blue RC, or by mineral colours, such as iron oxide and chrome green. In an example, 100 parts of cement and 300 parts of sand are gauged with 20 parts of water, and 10 parts of a saturated solution of ammonium carbonate are added. In another example a slurry for application to a wet concrete surface comprises two parts of cement and 50 parts of water. As soon as the wash has been applied the whole is sprayed with a saturated solution of ammonium carbonate. Specification 277, 389 is referred to.

Abstract: 427,032. Road signals for controlling traffic. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, and PREIST, T. P., 104, Deveroux Drive, Poulton, Wallasey, Cheshire. Oct. 14, 1933, No. 28467. [Class 118 (ii)] In a neon-tube -condenser timing arrangement, such as is used for timing roadtraffic control apparatus, in which the condenser can b e intermittently shunted by resistances to increase the time period, the resistances are bridged by neon-tubes to ensure that the voltage across the condenser drops below the critical voltage of the timing neon-tube if one of the shunting resistances is connected for a very short time period. The invention is described as applied to the system described in Specification 403,732 and the Figure shows the amendments required to part of Fig. 3 of that Specification. The resistances YD, YE are bridged by neon tubes FD, FE so that if condenser QA is charged to a voltage above the striking voltage of tube FA when the shunting resistance is connected up, the corresponding tube FD or FE flashes to reduce the voltage across condenser QA instantaneously to a voltage below the critical voltage, the condenser then discharging through the resistance for the time during which contact e2 or contact d2 is closed.
