Title: Spectral analysis system including hollow cathode element for combined emission of spectral radiation and resonance detection
IPC: G01J3/10
Filed: 1968-12-31
Abstract: 1,201,005. Glow discharge lamps. WESTINGHOUSE ELECTRIC CORP. 31 Dec., 1968 [10 Jan., 1968; 24 Oct., 1968], No.61906/68. Heading H1D. [Also in Division G1] A single hollow cathode tube is used to provide both radiation emission and resonant detection in atomic absorption spectroscopy. In the arrangement of Fig. 4, the cathode has a two-part bore, the narrow part providing light beam emission, by excitation of sputtered atoms from the cathode, (region 24) and the wider part providing a cloud of ground state atoms in region 25 to act as a resonant radiation detector region. The anode 28 is cylindrical. The support and insulation structure for the electrodes, involving insulating discs, is detailed in Fig. 1 (not shown). In two modifications of this structure, the cathode is made of two parts, one having the narrow bore and the other a wider bore, Fig. 5 (not shown) and the anode separates the two parts of a two-part cathode, Fig. 6 (not shown). In the arrangement of Fig. 7, the anode 130 is off the axis of the tube, the cathode has a uniform bore and an auxiliary annular electrode 150 is used to provide the resonant detection zone. It is of the same material as the cathode and is at a potential more negative than the cathode and thereby forms a cloud of ground state atoms at zone 182. Spacer/screen members 138, 140, 170 of silica, porcelain, alumina &c. are provided. A couple of modifications of this structure are described. In Fig. 8 (not shown), the auxiliary electrode is off-axis. In Fig. 9 (not shown), the auxiliary electrode is heated. Further modifications involve: the use of an insulating sleeve extending from round the cathode, Fig. 10 (not shown); an annular anode, Fig. 11 (not shown); a sequence of spacer discs between cathode and anode, Fig. 12 (not shown); a cathode in the form of a tube, open at both ends, and an anode on the opposite side of the cathode from the radiation emitting end, Fig. 13 (not shown). Cathode materials mentioned are nickel, brass, magnesium; and anode materials, tantalum, nickel, tungsten. The gas filling is neon, argon or helium.

Abstract: 664,383. Measuring selectivity of resonant circuits. COMPAGNIE GENERALE D'ELECTRICITE. Dec. 20, 1949 [Feb. 8, 1949], No. 32568/49. Class 37. In apparatus for measuring the selectivity or Q factor of a resonant circuit, a cyclically variable frequency is applied from 12, Fig. 1, to the circuit 1 under test, and the output is applied to one pair of plates 3 of a cathode-ray tube 4, the other pair of plates being supplied with a voltage related to the injected frequency so that the cathode-ray tube depicts the normal resonance curve; the variable frequency is also applied from 12 to a sharply tuned circuit 11 whose output is rectified at 8 to produce a voltage variation as in Fig. 2; a differentiating circuit 15, 16 produces the curve of Fig. 3, and after amplification at 17, is applied over transformer 26 to diodes 19, 20 to produce the signal shown in Fig. 4 which has a trough corresponding to the frequency to which circuit 11 is tuned; the signal of Fig. 4 is applied to modulate the intensity of the cathode-ray beam so that at the frequency to which circuit 11 is tuned the curve on the cathode-ray tube has a bright spot 51, Fig. 5, with dark areas 52, 53 on each side of it. By varying the tuning of circuit 11, the spot 51 can be moved to any point on the line C, and measurements may be made with great accuracy to determine the selectivity of circuit 1. The diodes 19, 20 may be replaced by triodes, Fig. 6 (not shown).

Title: Ultrasonic Wet Grinder
IPC: B02C19/18
Filed: 1979-01-04
Abstract: A slurry of coal and a liquid which includes a leaching agent is directed through a chamber (18). The coal particles are comminuted and cavitation is induced in said slurry while the slurry is in the chamber by contact in the slurry with a resonant vibration-transmitting member (20, 22) which ensures that there are no inactive regions of vibratory energy through which the slurry can flow.

Title: Electrolytic purification of effluents
IPC: C02F1/465
Filed: 1980-03-07
Abstract: Effluent is treated by passing it through an electrolytic cell 12 having aluminium anodes 22. In the electrolysis, gas is evolved which carries certain of the particles in the effluent to the top of the cell to form a foam, and this foam overflows from the top of the cell. The electrolysis also produces a flocculating agent which causes other suspended particles in the effluent to coagulate and drop to the bottom of the cell. Clarified effluent is removed continuously from near the top of the liquid region in the electrolytic cell, and effluent to be treated is continuously fed into the cell. The effluent removed from the cell may be further treated by filtration before discharge. <IMAGE>

Title: Electro acoustic transducers
IPC: H04R11/00
Filed: 1980-04-15
Abstract: Electro-acoustic transducers, e.g. armature receivers used as the ear-pieces of standard British Post Office telephones, have hitherto been assembled by thread-rolling screws between the drive unit (yoke, magnet system and armature) and the frame. This has disadvantages, and to overcome these the assembly uses plain rivets. In one form, Fig. 5, the rivet is a separate item with a flange (10) between its ends to locate when its lower end is fitted to a hole in the frame. This lower end is ironed over (11) to lock the rivet to the frame, and the upper end is fitted through a hole in the end (12) of one arm of the armature and a hole in the yoke (13). The upper end is then ironed over (14) to lock the assembly together. To facilitate assembly the drive unit plus rivets are fixed together as a sub-assembly for attachment to the frame. In a further form, Fig. 7, each rivet is formed by an upstanding pillar (20) integral with the frame which, when the device is assembled, fits through a hole in the end (22) of the armature arm and a hole in the yoke (21) after which the upper end is ironed over (23) to hold the assembly together. <IMAGE>
