Abstract: 447,486. Testing ignition. FROST, S. J., 31, Arlington Park Mansions, Chiswick, London. Nov. 19, 1934, No. 33239. [Class 7 (iv)] A testing device for mounting on a sparking- plug or which may be enclosed in a casing mounted on a dash-board comprises a member which may be moved between a fixed member and an earthed member producing a gap either in series or in shunt with the sparking-plug electrodes. As shown in Fig. 2, a fixed lead E is connected to a sparking - plug central electrode ; a movable lead B<1> from the distributer is clamped to a slide B and the position of its end relative to the fixed terminal e and an earthed bar may be adjusted as required. In the construction shown in Fig. 3, a plate J secured by the nut at the top of the plug electrode has upstanding notched conducting strips, one being in electrical connection with the electrode and the other with the casing. The plate J also carries a resilient holder for the current lead the end N<1> of which may engage the notch in the strip J<1> giving an uninterrupted circuit, or the notch k<1> short-circuiting the plug to earth, or be placed in varying positions between the points k<2>, j<2>. The movable terminal may be mounted in a block or insulating material slidable on the outer end of the plug.

Abstract: 789,260. Cold separation of gas mixtures. NAAMLOOZE VENNOOTSCHAP. Nov. 25, 1955 [Nov. 29, 1954], No. 33836/55. Class 8(2). In a process for liquefying a gas mixture with or without separation comprising condensing low volatile impurities, e.g., water vapour and carbon dioxide on apertured plates 18, Fig. 1, extending from a carrier rod 16 of a heat exchanger 17 connected to a thermal sink 21 from which heat is extracted by a gas refrigerator of the reversed hot gas engine type, a second heat exchanger may be connected to the sink 21 whilst the first is being defrosted. The cold end of the rod 16 forms a socket engaging a projection 14 at the top of the freezing space 8 of the refrigerator. In a modification that of a pair of exchangers 75, 76, Fig. 3 in use, e.g., exchanger 76 is connected by a pipe 96 to the condensing space 72 surrounding the cold end of the refrigerator 70 and an auxiliary liquid is forced by a pump 95 from a chamber 71 through a pipe 92 to a chamber 82 separated from the plates 80 but surrounding the cold end of the carrier rod 78, and the resulting vapour is returned through pipes 88, 90 to the chamber 71. When exchanger plates 80 are clogged valves 89, 93, 98 are turned to disconnect this exchanger and to bring exchanger 75 into circuit. In a further modification a pair of heat exchangers 43, 44, Fig. 2, are located beneath the boiler 31 of a rectification column 30 and are spaced from the boiler by chambers 35, 36 normally charged with air at 4 atmospheres pressure and containing plates 33, 34, 39, 40 serving to conduct heat to the boiler bottom 32. In operation atmospheric air is drawn through a duct 45 and the heat exchanger 43 in use, and impurity-free air then passes along a valved duct 49 to the column 30 from the top of which nitrogen gas issues to the refrigerator 64 where it is condensed and returned through a duct 65 as reflux. The heat exchanger 44 not in use is defrosted by warm air entering through ducts 52, 50 and leaving through the normal air entry 46, any liquid air in chamber 36 having first been drained through a duct 56. Specification 746,436 is referred to.
