A portable instrument, to determine the amount of a particular gas e.g. methane in underground air current, has a built in electrical battery supply, a moving coil meter to indicate the state of charge of the battery Figs. 2, 3 and 4 (not shown) and a known type voltage stabilizing circuitry Figs. 3 and 4 (not shown), to stabilize the voltage supplied to a bridge circuit in which is connected a detector (not described) sensitive to a particular gas. The state of charge meter scale is calibrated to indicate that a further 50, 100, 200, or 300 readings can be taken. The instrument may include an electric motor driven pump to supply gas to the detector which motor may be controlled by a transistorized timing circuit Fig. 4 (not shown).

Title: Centrifugal atomizer for liquids
IPC: B05B3/10
Filed: 1957-01-07
Abstract: 806,848. Rotary sprayers. AMBERG, W. E. Jan. 7, 1957, No. 612/57. Class 69 (3). Liquid from a supply 19 is fed to the hollow hub 11 of a rotary member 10 driven by a shaft 15, and passes through radial passages 18 and between the base of a cone 29 and a circular plate 13 to a shallow annular chamber 21 in the said plate. Centrifugal forces cause liquid to flow over the annular edge of the chamber 21 to a second annular chamber 23 from which the liquid passes via grooves 25 into reservoirs 44. The latter are provided within a bracket 33 riveted to the plate 13, and each reservoir, in which liquid is trapped by centrifugal forces, consists of a wall 35 of the bracket and a flange 43 which faces in the direction of rotation. The trailing sides of each reservoir include a linear spillage edge 45, Fig. 3, parallel to the axis of rotation, from which liquid is flung in atomized form at a rate depending upon the liquid feed rate. Fan blades 47, 51, Fig. 3, located inwardly and outwardly of the spillage edges create air currents which aid the dispersion. In the embodiment of Figs. 8 and 9 a bracket 64 is secured to a rotary plate 61 containing an annular chamber 63 to which liquid is fed via a hollow hub 65. Liquid is trapped in the chamber and within reservoirs 69 formed by walls 67, 68 of the bracket and, depending on the liquid feed rate, flows in atomized form from spillage edges 70. Fig. 11 shows an embodiment in which liquid is fed from a hollow hub 83 and hollow bosses 89 to reservoirs 87 each having a spillage edge 88. The atomizer of Figs. 13 and 14 includes a rotary body 101 on hollow shafts 102 through which liquid is fed to annular chambers 108. The body 101 consists of walls 103 joined by webs 104, and provides four reservoirs 105 in which liquid is trapped. Liquid flows from the chambers 108 to the reservoirs and is atomized from the spillage edges 106. In a further construction the webs 104 are omitted.

Abstract: 684,290. Tampon introducers. TAMPAX, Inc. Jan. 9, 1951 [Sept. 9, 1950], No. 644/51. Class 81 (ii). In a tampon applicator of the type comprising inner and outer telescoped tubes, a portion of the wall of the outer tube is deformed to provide a finger abutment and a portion of the wall of the inner tube is similarly deformed in the corresponding area to provide releasable interlocking between the tubes. In one form small depressions 5 are formed in the wall 2 of the outer tube and the wall 4 of the inner tube is similarly shaped to lock the two tubes. A relatively sharp abutment 6 at the lower edge of each depression prevents the inner tube being withdrawn accidentally. In an alternative form the deformations are directed outwardly.

Title: A method of purifying silane or chlorinated silanes
IPC: C01B33/107
Filed: 1959-01-09
Abstract: <PICT:0893495/III/1> Silane, mono-, di-, or tri-chlorinated silane, or silicon tetrachloride substantially free from borane, or chlorinated boranes, are produced by passing the gaseous silane or chlorinated silane containing the borane impurities over a porous, inert carrier impregnated with one or more organic or inorganic, solid or liquid substances the molecules of which contain a N, P, O, Cl, or F atom and a lone pair of electrons, which substances form non-volatile addition compounds with the borane, or chlorinated boranes.  The impregnating substances may be cyanogen bromide, acetonitrile, propionitrile, succinodinitrile, cyanamide, o-, m-, or p-dinitrobenzene, dimethylaniline, azobenzene, caprolactam, benzaldehyde, methyl ethyl ketone, dimethyl glyoxime, valerolactone, dioxan, phosphorus oxychloride, phosphorus trichloride, diethyl phosphine, triphenyl chloro-, or fluoro-methane, aluminium chloride, or ferric chloride.  The carrier may be granulated active carbon, silica gel, or pumice stone, which may be soaked in a solution of the impregnating substance in a dry volatile solvent, e.g. diethyl ether, a ketone, or methylene chloride.  The impregnated carrier is placed on plate 7 in absorption tube 2 of the quartz apparatus shown.  The silane, or chlorinated silane is distilled from flask 1 through the absorbent at - 100 to 100 DEG  C. so that addition compounds are formed with the impregnant and absorbed on the carrier.  The purified silane or chlorinated silane passes through cooler 4 to receiver 6. Silicon may be prepared from the purified silane or chlorinated silane by thermal decomposition, e.g. by high-frequency heating, in a closed vessel with, or without, a gaseous reducing agent, e.g. H2 Si is deposited as liquid on a collector which is moved out of the decomposition vessel so that the Si crystallises as a rod.  The Si rod may be purified by zone refining. Specifications 834,380 and 891,532 are referred to.

Title: Debossing and perforating a polymeric web
Inventor: CURRO JOHN JOSEPH
IPC: B26F1/26
Filed: 1992-07-09
Abstract: @ A continuous, multi-phase process for debossing and perforating a substantially continuous web of substantially planar polymeric film to coincide with the image of one or more forming structures, each having a patterned forming surface with a multiplicity of holes and an opposed surface. Each forming structure is open from the holes in the forming surface to its opposed surface. The web of film has an indefinite length, a first surface, a second surface and a thickness. The thickness comprises the distance between the first surface and the second surface. The process comprises at least two sequential.forming phases, one of which involves three-dimensional conformance of the web to the macroscopic profile of the forming structure and another of which involves aperturing of the web to coincide with fine-scale apertures in either the same or a separate forming structure. The order in which the phases are carried out will depend upon the properties desired in the resultant macroscopically expanded, three-dimensional, apertured polymeric web. Because the process is carried out in sequential phases, previously incompatible characteristics which could not be provided by prior art single-phase forming processes can now be achieved.
