Abstract: 295,773. Gulliford, A. G., and Maurice, W. May 27, 1927. Gas analysis. In miners' safety lamps provided with a platinum wire or like device for indicating the presence of methane &c., a varialbe resistance is included in the circuit of the indicator to enable the amount of methane to be estimated. The platinum wire is preferably mounted so that it is observed through a tinted glass, and the resistance is adjusted until the glow of the wire is just visible, the percentage of methane being then read on a previously calibrated scale. Fig. 1 shows one form of the apparatus wherein the methane detector is contained in a casing h bolted to the lamp case a. The filament is secured between screws k<14> and is visible through the glass h<9>; the atmosphere has access to it through perforations in the casing h. The variable resistance k<1> is wound on an annular former and contact is made to it by a radial arm k<3> rotated by a knob to which is attached a pointer h<5> traversing a scale on the top of the casing. Connection with the battery is made through studs f, f<1>, f<2> (see Fig. 2) contacting with studs e, e<1> e<2> in the lamp casing, which are themselves connected to contacts d<1> - - d' in the underside of the top of the battery case. This can be rotated so that the battery terminals make contact either with d<1>, d' or with d<2>, d<4>; in the latter case the fuse and the lamp are in parallel with one another and the resistance in series with both; in the former case the resistance is short-circuited. A screw h<5> serves as a switch for breaking the fuse circuit, leaving the lamp alone in operation.

Filed: 1975-04-08
Abstract: 1494874 Pick-up tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 April 1975 [8 April 1974] 14351/75 Heading H1D In a television camera tube with an auxiliary light source 30 for providing bias illumination to the screen, a light conductor 17 transmits the light from the source to a light distributer 21 which is included in the space between the anode sleeve 10 and a hollow auxiliary cylinder 15 which is coaxially mounted therein and which extends beyond the light distributer in the direction of the target to modify the distribution of the bias illumination over the target. As shown, in a vidicon tube, the light conductor-which may be a glass rod or a glass fibre bundle-is bifurcated, the two branches preferably lying in the line scanning direction, or it may be cone shaped. Preferably, the inner as well as the outer surface of the auxiliary cylinder is made diffusely reflecting, and the light distributer 21 may be of frosted transparent or of diffusely transparent material, and may be wither-as shown-spaced from, or sealed to, or integral with, the light conductor. A desired non-uniformity of the bias illumination over the target, to compensate for non-uniform sensitivity of the latter, may be produced by suitable positioning of the auxiliary cylinder 15; by profiling its end which faces the target (22, Fig. 2, not shown), or by forming apertures (23) in its circumferential wall; by modifying the light transmission of the light distributer 21 by a continuously or discretely varying block layer applied thereto; and by modifying the shape of the anode sleeve 10 adjacent the target, as at 27, or modifying the reflectivity of its inner surface in that neighbourhood. The light source 30 and a filter 29 are mounted against the base of the tube, e.g. by cement, the pump stem portion 28 of the envelope acting as a lens, and the initial portion 31 of the light conductor being coated with a reflective film to reduce the escape of stray light into the tube.

Title: Improvements relating to abrasive wheels
IPC: B24D3/34
Filed: 1935-05-17
Abstract: A composition for use in making an abrasive wheel consists of abrasive grains united by an organic bond, such as vulcanized rubber or a phenolic resin, and a finely divided insoluble fluoride, which renders the wheel incapable of being softened by normal grinding temperatures.  The fluoride may consist of cryolite, calcium fluoride, apatite, and the like.  The quantity of cryolite may be between 20 and 40 per cent by volume of the bond in the case of a rubber bond, or from 15 to 25 per cent in the case of a resin bond, or smaller quantities may be employed with lesser effects.  The powdered cryolite may be mixed with powdered resin, and the abrasive grains moistened with a sufficient quantity of a liquid resin to make up the desired amount of resin, the whole being then mixed. Alternatively, the grains may be given a coating of binding material such as glue, shellac, rubber, or resinoid material, and the cryolite is then dusted over them, the coated grains being then mixed with the rubber or resinoid bond.

Title: Transsistorized vertical deflection circuit
IPC: H04N3/23
Filed: 1971-05-13
Abstract: 1348034 Vertical deflection circuit RCA CORPORATION 13 May 1971 [15 May 1970] 14768/71 Heading H3T In a vertical deflection circuit using a class B output stage of complementary, series-connected transistors 40, 50, having their joined emitter connected to a deflection coil 80A, 80B and their bases to a driver transistor 30, the base of the transistor (40) which is conductive during the fllyback period is coupled to means which clamps the peaks of the flyback pulse to a constant potential. This maintains the amplitude of the sawtooth wave produced constant. As shown, the means is a Zener diode 36. The circuit is a self oscillating Miller integrator using integrating capacitor 61 connected to a resistor 57 in series with the deflection coils 80A, 80B, positive feedback being provided through a resistor 101. Diode 63 permits the capacitor to discharge only to 0À6 volts and consequently when the integrator operates by transistor 100 turning off, the Vbe of transistor 20 is instantly cancelled so avoiding a step in the sawtooth wave produced. To avoid "pin-cushion effect", horizontal waveform components are fed-in at H, H<SP>1</SP> through the vertical deflection coil, this consequent interference in the integrator circuitry being avoided by shunting the coil 80B with a capacitor 90 whose impedance is half that of the impedance of the coil 80B to the horizontal waveform components. This produces a current through capacitor 90 in the opposite sense to that through coil 80B and of twice the magnitude. When impressed across resistor 87, it is the opposite sense to the current through resistor 86 and, due to the horizontal waveform and the currents cancel. Series tuned circuit 103, 015 and capacitor 55 also aid suppression of the horizontal wave. "S" correction is effected by double integration in 91 1 -95 of the sawtooth waveform. Interaction of the height control 10 and frame hold controls 56 is avoided by appropriate feedback via resistor 52. Variations in the EHT supply +KDC are also coupled in this network to cancel any effects EHT variations may have on picture size. "Sync." is provided via differentiator 111, 112 and via integrator 115, 58.

Title: Process for the manufacture of lubricating oil
Inventor: GLEIM WILLIAM KARL THEODORE
IPC: C10G65/04
Filed: 1959-05-04
Abstract: Lubricating-oil is obtained from a hydrocarbon oil fraction at least 95% of which boils above 285 DEG  C. and containing condensed ring naphthenes by contacting the oil with a hydrogenation catalyst on a non-acidic support in the presence of hydrogen to convert the condensed ring naphthenes to aromatic compounds, and separating aromatic compounds from the non-aromatic compounds which are recovered for use as lubricating oil.  Any olefines present in the oil will have been hydrogenated, while monocyclic naphthenes are unchanged.  Preferably the oil is first hydrodesulphurized, deasphalted and dewaxed.  The catalyst may be a platinum group metal, preferably platinum or palladium, nickel, cobalt, molybdenum or tungsten supported on alumina, silica, zirconia, magnesia, clays, kieselguhr, silica-alumina, or silica-magnesia which if acidic or not catalytically inert is treated with steam, alkali carbonate, hot water or ammonia or composited with alkali or alkaline-earth metal oxide, an amine or ammonia, or supported on carbon.  Conditions may be 260-480 DEG  C. and subatmospheric to 10 atmospheres pressure. Separation of aromatic hydrocarbons may be effected by solvent extraction with glycols, methanol, aldehydes, nitriles, dinitriles, or amines, by adsorption on silica gel, activated charcoal or Attapulgus or other clay or by precipitation with trinitrotoluene or picric acid.
