Title: Improvements in miners' and other portable lamps
IPC: H05B41/02
Filed: 1933-01-25
Abstract: 418,662. Electric lamps. HAILWOOD, E. A., Beacon House, Texas Street, Morley, near Leeds. Jan. 25, 1933, No. 2356. [Class 39 (ii).] A portable electric lamp adapted more particularly for miners' use, is provided with a luminous electric discharge tube as the source of light, the luminous discharge being initiated by connecting the lamp terminals to an electric circuit of comparatively high voltage, after which the terminal connections are transferred to a comparatively low voltage source such as accumulators or a small dynamo driven by compressed air. A transformer, induction coil, or the like may be interposed in the low voltage circuit in order to obtain a voltage sufficient to maintain the glow discharge. The lamp is provided with a switch to enable the change over from the high voltage starting circuit to the comparatively low voltage operating circuit to be effected, and means such as a magnetic lock or sunken terminals may be provided to prevent tampering. A small electric incandescent lamp bulb may be provided as an emergency lamp in the event of the glow discharge lamp failing. In the example the lamp is provided with a switching device comprising an insulating member S mounted transversely within the upper portion of the battery casing, and provided with contacts S<1>, S<2> and S<3>, S' connected to pins S<5>, S<6> adapted to make contact with spring-pressed pins P<1>, P<2> on a high voltage supply plug P when the member S is in its inner position, the terminals N<1>, N<2> of the glow discharge tube N then being in contact with the contact faces S<2>, S<3>. The member S is screw-threaded at its other end to receive a screw-cap T which is rotated to move it longitudinally to withdraw the pins S<5>, S<6> from the plug contacts and bring the contacts S<1>, S<3> on to the accumulator terminals A<1>, A<2>. Further movement of the member S puts the accumulator terminals in circuit with the terminals L', L<2> of an electric incandescent lamp bulb L. A guiding-pin R fixed on the side of the casing engages an apertured lug R<1> on the insulating body S to prevent rotary movement of that member.

Title: Electric purification of liquids
IPC: B01D61/42
Filed: 1931-01-24
Abstract: 371,837. Electrolytic cells. BILLITER, J., 12, Reithlegasse, Vienna. Jan. 24, 1931, No. 2442. Convention date, Jan. 27, 1930. [Class 41.] A cell for the purification o f liquids is built up of frames R each of which is provided with a pair of diaphragms D tightly inserted therein to enclose an electrode space and is formed with a recess co-operating with the adjacent frame to form a space H for the passage of the liquid to be purified. A flow of liquid into the electrode spaces for flushing is promoted by maintaining the hydrostatic pressure therein below that in the intervening spaces. The electrode spaces may be kept empty of liquids, if desired, by suitable choice of the diaphragm material and the operating conditions. The electrodes E may be of graphite or magnetite in plates or in granulated form. The spaces H are connected by passages p at the bottom and passages q at the top of the frames. The frames R are cast from a readily fusible insulating material such as bitumen with mineral fillers, asphalt cement or kerasolith, and may be recast when worn out. Jointing of the frames may be effected by surface fusion and compression. The electrodes are preferably connected in bipolar relation, 10-36 of them being connected across a voltage of 220. The diaphragms may be of filter cloth asbestos, porous vulcanite, asphalt or ceramic materials. When flexible materials are used the electrode material, if granular, should be placed between perforated plates or in perforated baskets protected by asphalt. The electrode chambers may be open but should be provided with tight lids when treating liquids containing chlorine.

Title: Improvements in or relating to manufacture of hydrazine
Inventor: WOMER ROBERT LEROY
IPC: C01B21/16
Filed: 1952-02-04
Abstract: In the manufacture of hydrazine by reacting sodium hydroxide successively with chlorine and ammonia, the hydrazine is dehydrated with sodium hydroxide and the resulting aqueous sodium hydroxide is used in the manufacture of further hydrazine.  The aqueous solution of hydrazine first produced may be concentrated, before treatment with sodium hydroxide, by distillation to give a solution of up to 64 per cent strength.  If anhydrous hydrazine is desired sodium hydroxide is added in the proportion of at least one mole of sodium hydroxide to each mole of water present.  The resulting mixture when heated above 60 DEG C forms two liquid layers the upper layer consisting predominantly of hydrazine and the lower of sodium hydroxide monohydrate.  The upper layer may be removed by distillation under reduced pressure at a temperature between 60 and 80 DEG C to give substantially anhydrous hydrazine.

Fig. 2 is a longitudinal section of a machine having an aperture 16 through which the operator inserts the spring to rest on a glass plate 18. A light pipe 40 directs light from a lamp 42 (see also Fig. 3) and reflector 44 on to the spring end, and the image is formed on screen 37 by lenses 32 and mirrors 34, 36. A rotatable glass plate 38 bears an engraved pointer corresponding to the desired position of the end of the spring wire, or positions if left and right-handed springs are to be looped. The glass plate 18 is mounted in a plate 12 adjustable for focusing by screw 192. When the spring has been gripped (see below) the glass plate 18 is withdrawn by air motor 22, Fig. 3 (plan), pivotable about support 24 by a screw 26 to adjust the height of the spring relative to the loop forming tools. When the spring has been correctly orientated, it is gripped by three jaws 58, Fig. 5, slidable in grooves 56 by cams 64 and slots 62 in disc 60 rotatable by lever 72 and air motor 86 (see also, Fig. 3). A further arm in the lever works between stops 76 on a slider adjustable and lockable by knob 82, so that the travel of the jaws 58 can be set for various spring sizes. The loop forming mechanism is shown in Fig. 3, and comprises a coil opening tool 168, anvil 106, and striker 132. Each tool is mounted in a block 166, 102, 130 supported by rods 162, 96, 98 and arms 160, 92, 94 on pivots 158, 90. The tools are operated by cam members 172, 110, 138 movable between fixed surfaces 190, 114, 142 and inclined surfaces 188, 112, 140 on the blocks by air motors 170, 108, 136. Return springs 176, 118, 146 are provided. To vary the loop formed, each air motor is bodily movable along its axis by a respective lead screw mechanism operated by screws 184, 126, 154.
