Patent GB-113757-A (GB)
IPC: H01R33/945
Abstract: 113,757. Wirt, C. Sept. 17, 1917. Holders.-A stationary driving resistance surrounds the socket proper and is cut in and out in sections by a switch which may also serve to open the circuit. In a screw holder, the resistance 2 may be embedded in a hollow cylindrical or cup-shaped body, with or without inner and outer metal facings. The screw socket may be formed in the resistance body or may be separate therefrom as shown. Four bars 4 attached to the ends and two intermediate points of the resistance form switch contacts in the upper surface of the resistance body, one bar being also secured to the lining of the resistance body and thus connected to the socket. A switch blade 35 sweeping over the contacts, and a similar blade 13 bearing on the resistance body, are cut out at opposite points from an annular plate 41 on the lower face of a flanged rotary insulating ring 12. The plate 41 and a flat ring 43 are secured by flanges at the opposite ends of a lining 44 of the rotary body 12, relative rotation of the switch plate 41 being prevented by indenting it into holes in the body. A hollow metal cylinder 29, flanged at its lower end and forming the bearing for the rotary body 12, is in contact at its upper end with an annular plate 31 having an extension carrying a terminal 16. This is situated in a recess in an insulating body 8, provided with a rim 22 around the rotary body 12, and with a boss 32 projecting into the bearing 29. The second terminal is on a plate 28, held in a recess in the insulating body 8 by a screw 9, the head 25 of which forms the central lamp-engaging contact and clamps the socket 1, with the interposition of an insulating plate 10 and preferably of a countersunk washer 26. Indents 17 or the like prevent rotation of the socket in the resistance body. Around the rotary switch body 12 is fitted a metal ring 34 with a flange which co-operates with the flange on the body 12 to form a groove for actuating-chains 14. These are attached to staples, the bends of which project into the grooves while the ends fit under the edges of holes in the metal ring 34. If the chains are of the form shown, they may be secured by having their end knobs within the slotted staples. A flaring mouthpiece 45 for guiding the chains has an extension 48 entering a groove in the resistance body to prevent its rotation, and an upper extension secured by a screw 46 passing through the insulating body. The same screw holds a bent plate 47 which limits the rotation of the switch body. The dome section 50 of the casing, which may have an insulating lining, fits over the edge of the lower section of the casing. To secure together these sections, small plates held within the casing at the joint by set-screws have opposite edges bent up and respectively projecting through holes in the dome and engaging the shoulder of a beading 53 around the lower section. In a bayonet-joint holder, the screw 9 is connected by a plate to one plunger-cylinder, and the other cylinder makes contact at its inner end with the lining of the resistance body.

Title: Apparatus for the analysis of mixtures of gases by means of gas absorption percolation
Inventor: KEULEMANS ALOYSIUS IGNATIUS MA
IPC: G01N30/30
Filed: 1955-04-22
Abstract: <PICT:0784169/III/1> The invention relates to apparatus for the analysis of gas mixtures in which the mixture together with a carrier gas is passed over an elongated bed of porous inert particulate solid material impregnated with an immobile liquid, the bed being of such a length that the gas issuing therefrom comprises in succession the components of the mixture together with the carrier gas; such apparatus also includes an instrument for measuring a significant physical property of the gas leaving the bed. According to the invention the absorption column containing the elongated bed, the part of the measuring instrument in which the gas is present during measurement, and the connecting conduit are all situated in a single temperature controlling device.  As shown, the gas to be analysed is introduced at 8 into helical absorption column 1; carrier gas enters at 6 and passes through the reference channel a of a thermal conductivity cell 2 before mixing with the gas to be analysed; gas leaving the column passes through the measuring channel b of the conductivity cell. Platinum wires are suspended in the channels and connected to a Wheatstone bridge for measurement of resistance.  The whole assembly is arranged in a thermostat vessel 3 provided with heater 4 and stirrer 5.  In this apparatus aromatic constituents of a hydrocarbon fraction may be analysed, using nitrogen as the carrier gas, diglycerol as the immobile liquid, and diatomaceous earth as the inert solid.  Alternative methods of analysing the gaseous components are (a) when using carbon dioxide as the carrier gas, removing this by washing with caustic alkali solution, and then measuring the pressure of the remaining component at constant volume or its volume at constant pressure; (b) absorbing the components in a reagent solution and measuring the electrical conductivity of the resulting solution.  Suitable liquids for use in the column are liquid paraffins, dinonyl phthalate, and dimethyl formamide.  Mixtures which may be analysed include paraffinic and olefinic hydrocarbons, and mixtures containing aromatic compounds, fatty acids, amines, pyridines, aldehydes, ketones, ethers, or alcohols.  The process may be carried out at reduced, ambient, or elevated temperatures and pressures.
