Title: Improvements in atomising apparatus for the production of medicinal mists
IPC: A61M11/00
Filed: 1951-11-26
Abstract: 721,458. Spray-producers. SMITH, J. V. BRIGHT-. Sept. 24, 1953 [Nov. 26, 1951], No. 27724/51. Addition to 606,845. Class 69 (3). A medicinal mist producer includes a phial 10 for the liquid to be atomised with an outlet 18 in its side wall, an atomising tube 13 from which atomised liquid is discharged radially outwards against a baffle sleeve 12, and means for varying the distance between an outlet opening 21 in the baffle sleeve and a precipitation surface 20 opposite that opening. In this manner the maximum particle size emitted from the outlet 18 is varied. The device is mounted on a frame 21, and the baffle sleeve may be slightly rotated relative to the phial and atomising tube by a knob 29. The undersurfaces of the rims 16, 17 of the baffle sleeve and a head part 14 respectively are part-spherical, and engage frusto-conical surfaces of the phial and sleeve. The part 14 includes a gas connector 24 which, by means of a pivoted clamping device 47, is held within a bush 33 to which an atomising gas supply is fed. The connector 24 depresses a valve 36 to allow the flow of gas through passages 22 and 27, and liquid is drawn up bores 28 and sprayed radially outwards. Tapered notches 48, 49, Fig. 5, formed in the lower ends of the baffle outlet 25 and tube 13 increase the space for the liquid to drain down into the phial when the sleeve is turned into a coarse mist position.

Patent GB-760190-A (GB)
Title: Improvements in and relating to electric width gauge apparatus
IPC: G01B11/04
Filed: 1954-09-30
Abstract: 760,190. Photo-electric width gauges. GENERAL ELECTRIC CO. Sept. 30, 1954 [Oct. 5, 1953], No. 28244/54. Class 40 (3). In apparatus for measuring the width of radiation-emitting strip, scanning devices traverse the edges of the strip in directions perpendicular to its length, photo-tubes receiving radiation directed from them by the scanning device producing pulses the width of which depends on the strip width, these pulses then producing square pulses which are used to derive a measure of total strip width. As shown, heated strip 13, the width of which is to be determined, passes over rollers 14, while scanning devices scan at right angles to the strip as indicated by the dotted lines. Phototubes 11, 12 situated above the cylinders receive radiation from the strip and produce output pulses as shown in Fig. 3a, the sloping leading edge being due to edge-cooling of the strip. The photo-tube output signals are amplified at 22, 23 and fed respectively through channels A and B where square waves are produced which are then added 26, filtered and fed to a circuit 28 which indicates the control to which the relays differ from its correct value. Circuit (Fig. 2). The circuit of preamplifier 22 and channel A, (24) only is shown. Photocell 11 receiving radiation from the heated strip is connected between the control and screen grid of a preamplifying pentode 38. The output of the pentode is connected through a differentiating circuit comprising condenser 48 and resistor 46 to the grid of a double-triode amplifier 47. The differentiating circuit produces a waveform as shown in Fig. 3B, the peaks 84 and 85 after amplification in triode being used to trigger a bi-stable multivibrator 64. In order to avoid false triggering of the multivibrator by negative peaks between the front and last tube as shown in Figs. 3A and 3B, the level of the signal is changed by feeding the undifferentiated signal also through condenser 48 and resistor 49 to the grid of triode 47. This alters the level of the signal as shown in Fig. 3C. Multivibrator 65 is of conventional type and produces square pulses, Fig. 3D, whose width depends on the distance between peaks 84, 85. These pulses are added to those produced by channel B across resistor 88, integrated in a double T-circuit and compared in a differential amplifier 97 with a voltage determined by the setting of a potentiometer 98, meter 102 thus indicating the deviation of the strips from its correct width directly. An automatic gaincontrol circuit 116 is included to take account of widely differing strip temperatures. The circuit in addition to reducing the sensitivity of pentode 38, because of the connection of photo-cell 11 between the control and screen grids reduces its sensitivity also.

Filed: 1971-06-17
Abstract: 1349367 Antistatic polyamide filaments and porous products thereof BADISCHE ANILIN- & SODA-FABRIK AG 17 June 1971 [18 June 1970] 28370/70 Headings C3R and C3C Synthetic linear polyamide filaments or fibres contain as a separate phase dispersed therein 1 to 15 wt. per cent of the reaction product of a synthetic linear polyamide of R.V. 1À5 to 2À9 (1 wt. per cent in 98% H 2 SO 4  at 20‹ C.) with 10 to 50 times its weight of a C 2-4  1,2-alkylene oxide. The reaction product may be formed according to Specification 1,349,368 and is generally not formed directly but by reaction of a reaction product of a polyamide with 1 to 4 times its weight of alkylene oxide with further alkylene oxide. Various polyamides suitable for forming the filaments and for the reaction products are specified; the former may contain 50 to 130 m.equiv./Kg excess basic groups on 50 to 150 m.equiv./Kg sulphonic acid or salt groups. The filaments may also contain pigments, e.g. TiO 2 , or light and heat stabilizers. When the filaments are treated with hot aqueous liquors some of the embedded particles of reaction product are dissolved out leaving cavities which contribute a soil-binding effect in addition to the antistatic properties conferred by the reaction product. In Examples the filament-forming polymer is nylon 6 or 66 and the reaction product is derived from nylon 6 or co-6/66 with 20, 25 or 18 parts of ethylene oxide.

Abstract: 749,682. Pulverulent-fuel furnaces. WALTHER & CIE AKT.-GES. Nov. 11, 1952 [Nov. 20, 1951 ; Dec. 13, 1951 ; Feb. 9, 1952 ; Feb. 9, 1952], No. 28431/52. Class 51(1). In a boiler furnace fired by pulverised fuel having an ash-melting hopper and auxiliary burners arranged below the main burners, the air supply to the auxiliary burners is so regulated in relation to the fuel supply that a reducing atmosphere is produced in a zone below the layer of gases produced by the main burners, fly ash being blown into this lower zone. Figs. 1 and 2 show a construction in which the furnace 10 is fitted at the corners with vertically tiltable main burners arranged in three superposed rows 13, 14, 15, auxiliary burners 18 and fly ash delivery nozzles 19 being disposed in alternate side walls of the ash-melting hopper 11 which in this case is constituted by the lower part of the furnace chamber 10. Fig. 7 shows a modification in which the lower part of the combustion chamber slopes towards a slag outlet 33 below which is a separate melting hopper 37 having auxiliary burners 38, secondary air nozzles 40 and nozzles 39, of which only one is shown, for the supply of fly ash. The hopper 37 is surrounded by cooling water tubes and is mounted on rails 57 so that it may be readily replaced by a spare hopper. This arrangement of a separate hopper is suitable for conversion of existing furnaces. Slag from the hopper 37 drops into a water bath from which it is removed by a conveyer 43; and in a modification drops into an injector supplied with water under pressure and is carried away in the water stream. In a further modification the returned fly ash is injected into the auxiliary fuel nozzles so as to mix with the fuel before its ignition.
