Patent GB-124455-A (GB)
Title: Improvements in Arc Lamps.
Inventor: WESTERCAMP GEORGES
IPC: H05B31/00
Filed: 1916-01-05
Abstract: 124,455. Westercamp, G. Jan. 5, 1916. Arc lamps.-In a search-light or other lamp having means for reducing the power consumption when desired, for instance when the light is masked, there is used as negative electrode a metallized or non-metallized carbon D provided with a core, or fed with liquid or gas; both means may be employed in conjunction. During reduced consumption, the tip of such an electrode retains the shape requisite for subsequent steady burning with normal consumption. The core may consist of carbon and an alkaline silicate, or of substances commonly used in positive or negative electrodes. A homogeneous mineralized carbon is not suitable. In the arrangement shown, a hand switch H and relay I control a short circuit across a resistance J in series with the lamp and generator F. In some cases, a lever K for altering the position of the carbons in accordance with the magnitude of the current is controlled by a second relay N. Specification 13358/12 is referred to.

Title: Improvements in or relating to processes and apparatus for testing gas samples
IPC: G01N21/72
Filed: 1962-01-19
Abstract: 998,532. Testing gas samples. O. H. DRAGER, [trading as DRAGER WERK, HEINR, & BERNH, DRAGER]. Jan. 19, 1962 [Jan. 19, 1961], No. 2106/62. Heading G1B. A gas sample containing oxygen, to be tested for the presence of sulphur or phosphorus-containing compounds as impurities, is burned so as to form a flame in an atmosphere of hydrogen. In a modification, a gas sample containing little or no oxygen is admixed with a stream of hydrogen, and a stream of oxygen is burned so as to form a flame in the resultant mixture. The presence of sulphur or phosphorus leads to a blue or green coloration in the combustion zone. As shown, a gas sample e.g. air, is supplied through tube 1 and narrow-bore extension 4 and after mixing with hydrogen supplied through tube 7 the mixture is ignited at the upper end 11 of quartz tube 5 surrounded by cooling jacket 9. The flane flashes back into tube 5 and produces a flame 12. In the modification, the sample gas would be admixed with the hydrogen entering through tube 7, and oxygen would be supplied through tube 1. An outlet 16 is provided for condensed water formed in situ. If the air contains phosphorus the flame 12 is intensely white and a green coloured zone 13 is formed. The green colour occurs also in the cone 14 within flame zone 15. With sulphur-containing compounds, blue coloured zones 13 and 14 are formed. In the absence of either element, flame 12 is bluish white. A spectrophotometer may be used to determine the intensity of the coloured zones, the portion of the zones to be investigated and suitable wavelengths being specified.

Title: Improvements in or relating to apparatus for examining crystalline structures by means of cathode rays
IPC: H01J37/295
Filed: 1947-01-09
Abstract: 634,788. Examination of crystals by X-rays. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Jan. 9, 1947, No. 759. Convention date, Jan. 12, 1946. [Class 98 (i)] [Also in Group XL (a)] In apparatus for examining crystalline substances by means of cathode rays, a magnetic lens 6 is placed between the crystalline object 2 and a screen 3, which may be fluorescent, the refractive power of the lens being such that the variation. in its effect resulting from a variation in the wavelength of the electron beam 1 compensates the effect on the diffraction pattern of variation in wavelength. If the lens were ineffective, the beam (if monochromatic) would be diffracted at an angle α to fall on the screen at a point 5, which would lie on a series of circles if the object 2 had a random arrangement of crystals. A beam of slightly greater wavelength would be diffracted at an angle α + # α to fall on the screen at 5<SP>1</SP>. It is found that if the power of the lens is such that the radii of the circles is reduced to substantially two-thirds of the value obtained without the lens, the two beams intersect the surface at a common point 7, so that the diffraction pattern is not blurred if the beam is not monochromatic, and fluctuations in accelerating voltage may be tolerated. An alternating accelerating voltage may be used if a control grid near the emitting cathode is arranged to be negative with respect to the cathode except in the region of the positive peak of the accelerating voltage, by applying the accelerating voltage, or an alternating voltage in phase with it, between the cathode and the control electrode through a resistor in series with a resistor and condenser in parallel. To avoid rotation of the image, the lens may have two elements with opposed fields. To avoid dependence on a steady current supply, the lens may be formed of permanent magnets.

In a web-roll changing mechanism of generally known construction in a rotary printing press, means are provided whereby when the difference between the square roots of the angular speeds of a web-engaging press-cylinder and the expiring roll 3 reaches a predetermined value a pulse is generated which produces signals causing simultaneous reduction of the press speed and initiation of a web-roll changing and splicing operation. A measuring motor generator 8 is driven from the press through a change-speed gearing 7, and another measuring motor generator 9 is driven from the core of the expiring roll 3 the rotary speed of which is dependent on the roll diameter. The generators are connected in opposition, and cause the impulse to be generated when the speeds of the press cylinder and roll 3 are such that the difference between the square roots reaches a a, predetermined value. The comparison between the square roots of the speeds of the generators may be effected by any suitable device that performs the required mathematical operation. A belt 4 for rotating the replacement roll up to the required speed is also driven from the press via the change-speed gear 7. Specification 986,082 is referred to.
