Title: Improvements in or relating to apparatus for quantitative analysis by means of x-rays
IPC: G21K1/06
Filed: 1937-11-23
Abstract: 506,022. Determining physical qualities of materials. HAMOS, L. VON. Nov. 23, 1937, No. 32203. Convention date, Dec. 21, 1936. [Class 37] [Also in Group XX] Apparatus for quantitative analysis by X-rays comprises an X-ray source, at least one crystal having a concave surface formed by a bent cleavage plane for focusing the X-rays, and two ionization chambers which receive two spectral images from the sample or samples. The sample 1 to be analysed and the sample 2 of known composition are both subjected to X-rays which produce secondary X-rays of wavelength and intensity dependent on the chemical composition of the samples. These secondary X-rays are diffracted by the concave surface of a crystal 4, and the ionization chambers are placed to receive rays having the characteristic wavelengths. The insulated electrodes of the ionization chambers 6, 7 are connected to a voltage source 8 over resistances 9, 10, an instrument 11 determining the difference in the potential gradients. A shutter 12 movable over the sample 2 varies the ionization in its chamber. When the instrument 11 is brought to zero, the scale position 13 of the shutter 12 indicates the amount of the element in the sample 1. In a modification, Fig. 2, a variable condenser 19 and fixed condenser 18 are connected in parallel to the ionization chambers 7, 6, and the capacity of the condenser 19 is varied until the discharge current in each is equal. The capacity of the condenser 19 is then a measure of the quantity of the element in the sample. Glow tubes or relays may be included to indicate equal rates of discharge in the ionization chambers. In a further modification, the image spectra are produced by two different crystals. In Fig. 5, the critical absorption of the X-rays by the sample is determined by passing the S radiation through the sample 27, the spectral images 28, 29 being measured in the ionization chambers 7, 6.

Abstract: 1501848 Boring earth &c UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 9 Aug 1976 [20 Oct 1975] 33021/76 Heading E1F A hole 26 is drilled in an earth formation 10 at the bottom of a borehole 14 using a laser beam 22 which is reflected into the earth formation 10, the borehole adjacent the formation 10 being pressurized with a gas transparent to the laser beam 22, the gas being at a pressure sufficiently greater than the pore pressure in the earth formation to force fluids generated by the laser drilling into pores and fissures in the formation 10 contiguous to the hole 26. The laser beam 22 drills the hole 26 by liquifying and/or vapourizing the formation 10 and the pressurized gas prevents the fluids produced from clouding the reflector 24 and reducing the efficiency of the laser beam 22. As described the borehole 14 is provided with a casing 16 which is sealed at its lower end by a rotary mounting 28 for the reflector 24. The reflector 24 can be rotated by motor 38 via shaft 40 and gears 36. The pressurized gas is supplied from a reservoir 44 via conduit 46. The gas may be air, nitrogen, oxygen or oxygen-rich air and has a pressure in the range 50 to 3,000 psig. The fissures in the formation 10 may be increased by pulsing the laser beam and/or varying the pressure of the gas. The invention may be used to provide starter bores which may be enlarged to establish interconnecting flow channels between several bore holes.

Title: Improvements in ozone apparatus
IPC: C01B13/11
Filed: 1922-12-05
Abstract: 211,982. Quain, J. R. Dec. 5, 1922. Gases, treating with electric discharges.-An ozone generator comprises a dielectric of material other than silica having its surfaces substantially vertical, openwork electrodes making contact therewith at numerous points, and a substantially vertical chimney surrounding but spaced from these parts, so that connection currents cause delivery of the ozone to the surrounding air. A non-resonant core within the electrodes &c. may consist of a transformer coil, which may be protected by wax; or the core may be below the ozonizing elements. An additional electric heater, such as a small lamp, may also assist in the production of the connection current. A single chimney containing a dielectric cylinder of glass &c. and a pair of electrodes 1, 2, may be mounted in a casing 5 containing electric supply devices. When the lid of the casing is removable, the chimney 4 may be secured to the base of the casing by means of a flanged ring 10. This clamps an extension 11 of the outer electrode, and serves as one terminal. A metal bar 13 extending across the chimney 4 bears on the top of the dielectric 3 and on an extension 12 of the inner electrode so as to constitute the other terminal. Numerous perforations 7, 6 in the bottom and top of the casing serve for admission and exit of air. A make-and-break device having an adjustable stationary contact, and operated by a coil controls the current through the primary of a transformer. A condenser shunts the contacts and primary winding. The secondary of the transformer is connected to the electrodes of the ozonizer. In one high-pressure lead is a spring- urged switch arm, which is raised by a conductive plug when it is desired to tap the current for use in a high-frequency applicator. The make-and-break device may be supported by a non-resonant pad. A number of tubular dielectrics may be mounted in a single casing, provided in its cover and base with openings enabling air currents to flow both inside and outside the dielectrics. An electric pressure of 10000 volts is suitable for a dielectric 1/16-1/12 in. thick. Specifications 4355/13 and 193.337 are referred to.
