Abstract: 823,436. Producing metal oxides by electrolysis. MAGNETO-CHEMIE N.V. Jan. 22, 1957, No. 2254/57. Class 41. A process for the coprecipitation of metal oxides containing 80 mol per cent or more of iron oxide by reacting the metal ions in predetermined ratios with a solution of an alkali metal salt comprising electrolysing the solution while introducing oxygen or an oxidation agent into the electrolysis vessel employing an anode of an alloy of iron containing the metals the oxides of which are to be precipitated, or employing an iron anode and separate anodes of the metals and adjusting the current strengths to the anodes so that the precipitated oxide contains the oxides in the desired ratios. Metals mentioned are Cu, Al, Ni, Mg, Zn, Cr, and oxidation agents mentioned are air, ozone, chlorine, hydrogen peroxide, nitric acid and aqueous solutions of nitrates and ammonium nitrite. Where separate anodes are employed, each anode is connected through a variable resistance and an ammeter to the current source. Electrolytes mentioned are potassium bromide or iodide and sodium bromide, preferably at a pH of 5.0 to 6.8. The temperature may be raised to 90‹ C., e.g. by passing A.C. through the bath via the electrodes or via auxiliary electrodes. In an example, the anodes were Fe, Cu, Zn, Ni, Mg and an iron cathode was employed, the electrolyte being sodium sulphate in distilled water. The current was adjusted so that 80% was received by the iron anode and a 1% solution of hydrogen peroxide was added to the electrolyte, this concentration being maintained. Specification 520,690 is referred to.

Title: Modular Seismic Cable Section
Inventor: SORKIN SAM A
IPC: H04L5/20
Filed: 1984-02-16
Abstract: The number of end connections and the weight and diameter of an oil floated modular marine seismic cable section (28) are reduced by reducing the number of both the local and through electric conduit pairs and the oil required for flotation thereof by employing the phantom pair technique for transmitting the hydrophone signals. The impedance matching transformers (A) of the hydrophones are used as parts of the bridge circuits used in the phantom pair technique, with similar transformers (B) at the receiving station (19) also being used as parts of the bridge circuits. Where the cables feed charge amplifiers similar reductions are effected by the use of capacitor bridges, see Fig. 7. The invention is also applicable to land seismic cables. <IMAGE>

Title: Digital data transmission
Inventor: CHAMBERS JOHN PHILIP
IPC: H04J3/24
Filed: 1984-04-16
Abstract: A digital data multiplex system transmits two packet types identified by respective packet type indicators comprising respective codes separated by a substantial Hamming distance. Advance warning of a change of packet type is given by transmitting in advance of the change one or a sequence of intermediate codes, in which some of the bits are altered from those of a defined one of the codes, but which is still closest in Hamming distance to that one of the codes. The intermediate codes are detected to give the advance warning, yet are correctable to the defined one type code.

Title: Dry-line liquid delivery system
Inventor: TAYLOR GEORGE SIDNEY
IPC: B67D7/04
Filed: 1984-04-17
Abstract: A liquid delivery system of the dry-line type, suitable for delivery of liquid from a liquid vessel such as a mobile tanker, has a first pump to supply liquid into a liquid delivery line, a second pump (P) to provide an independent supply of air under pressure, and valve means to introduce the pressurised air into the liquid delivery line, downstream of the liquid pump, when liquid delivery is completed.

Patent GB-2152584-A (GB)
Title: Centrifugal pump
Inventor: SCHAEFER JOHN G
IPC: F04D1/00
Filed: 1984-05-03
Abstract: A centrifugal pump has a casing (35) with an impeller cavity (48) in which a shrouded impeller (47) is mounted and with front and rear labyrinth seals (70-73) associated one with each of the front and rear shrouds (49, 50) of the impeller and located near the inner ends of the shrouds. An additional seal (76) is positioned inwardly of the rear labyrinth seal to substantially seal a space behind the innermost part of the rear shroud (50) and a pump structure (78, 79) is mounted on the impeller to the rear of the rear shroud for pumping fluid from the substantially sealed space to the entrance (55) of a volute surrounding the impeller. The impeller shaft has a front thrust bearing (80) coacting with a bearing surface (81), with fluid passing therebetween for lubrication and with the flow of the fluid being controlled to a minimal amount by a force imbalance on the impeller shaft created by location of the front and rear labyrinth seals (70-73) at different distances from the axis of rotation of the impeller (47) whereby pressure forces acting at the rear of the impeller urge the impeller shaft (45) in a forward direction.
Patent GB-2175469-A (GB)
Title: Symmetrical fault current detector
Inventor: AUBREY DAVID RICHARD
IPC: H02H3/08
Filed: 1985-05-20
Abstract: @ Excess currents due to faults in an electrical power system are generally larger than excess currents due to the magnetisation of distribution transformers: discrimination has hitherto relied on a threshold detector. Magnetising currents are however, asymmetrical whereas fault currents are symmetrical. This specification discloses a detector which can detect symmetrical current waveforms on a conductor 1 and thus discriminate between a fault and a magnetising excess current. A resistor 4, placed across the output terminals of a bridge rectifier 3 has a resistance selected so that the voltage across it exceeds the breakdown voltage of trigger diodes 7 and 8 when the current in conductor 1, in any half cycle, exceeds a desired maximum. Capacitors 13 and 14 will thus only both charge up in response to a large symmetrical current: a logic control 23 is connected via lines 21 and 22 to detect such a condition.

Title: Voice spectrum analyzing system
Inventor: NAKAMURA SHOGO
IPC: G10L17/00
Filed: 1986-11-21
Abstract: A voice spectrum analyzing system subjects a voice signal to frequency analysis by passing it through a filter bank containing a plurality of band pass filters each having a different pass band, to produce a voice spectral pattern over a predetermined frequency range. The voice spectral pattern is sampled at a predetermined sampling time interval, and each of the sampled voice spectral patterns Fig. 2a, Fig. 2b, Fig. 2c, is stored for a predetermined time period. While each voice spectral pattern is retained, it is scanned once in a predetermined time sequence, thereby forming an approximate periodic signal, Fig. 3, from a series of the scanned voice spectral voice patterns. The periodic signal thus formed is then digitized and filtered through a digital high pass filter, thereby obtaining a high frequency component from the periodic signal which indicates a feature parameter of the voice signal. This may be used to recognise the voice signal by comparison with a set of known data. The scanning may be carried out in the same direction for all spectral pattern or in opposite directions for successive pattern. A voice signal may be represented, at each sampling interval, by the output of a bank of band pass filters, and a voice power pattern. The voice power pattern is formed by multiplying the local peak in that sampling interval by a predetermined threshold, e.g. 20% to determine the top range of the sample and representing those of eight power levels which fall within this top range by "1" and the remaining power levels by "0". <IMAGE>

Title: Chain conveyor with connector for flight bars
Inventor: SNELLING KEITH
IPC: B65G19/24
Filed: 1987-06-18
Abstract: In a continuous chain conveyor, in which flight bars 3 extend between endless chain, a connection is effected between each end of a flight bar 3 and a horizontal link of a chain. A connector 4 is fixed to the end of the flight bar; the inner part 2b of the link is received within a recess in the bottom edge of the connector whilst the outer part 2a of the link rests on a tongue forming the outer end of the connector. The tongue is long enough to ensure that it lies in contact with the bottom of the part 2a throughout the maximum possible lateral movement of the connector 4 relative to the link. To limit that movement the part 2b of the link may be a close fit in the recess and the connector itself may be a close fit between the parts 2a and 2b. In a modification, the tongue may be one prong of a fork in which the part 2a fits closely. <IMAGE>
