Abstract: 1,216,069. Endless conveyer belts. CLOUTH GUMMIWERKE A.G. 1 Dec., 1969 [11 Dec., 1968], No. 58582/69. Heading B8A. A supervision apparatus for conveyer belts of rubber or similar material comprises electrically conductive inserts embeddedin the belt, each including two conductors 4, 5 lying closely side-by-side, or coaxially, and extending over approximately the whole width of the belt, and forming part of an open current circuit or an open inductive loop, at least one electric impulse transmitter 2, and at least one signal receiver 6 connected to a switch device 8 for actuating signalling and/or conveyer belt control means, the arrangement being such that signals are transmitted from a transmitter to a receiver if contact is established between the two conductors of an insert due to damage to the belt. The conductors 4, 5 may consist of cables sheathed with steel wire or of steel or copper braids. At least one of the conductors may be made tubular with the two conductors arranged coaxially. The system may be tested by bridging the conductors 4, 5, where they meet the edge of the belt (lower edge, Fig. 1). As shown, a current source 3 is in the form of a small battery 3. The signal is picked up by an aerial 7 in the form of an induction loop. The latter may be replaced by a series of aerials (7.1; 7.2; 7.3 . . . &c., Fig. 2, not shown). The battery 3 may be disposed outside the belt and is connected by contact rollers (14), (15), (Fig. 3, not shown) engaging conductors (12), (13), each connected to an end of respective conductors 4, 5. The conductors (12), (13) may be so arranged (e.g. at 16, Fig. 4, not shown) as to pick up signals from a transmitter 2 disposed adjacent the belt. Two sets of conductors (12), (13) may be disposed (as at 16, 16, Fig. 5, not shown) at respective sides of the belt and are connected to alternative sets of the conductors 4, 5. Alternatively, one of the conductors 16 may be connected to all the conductors 4 (e.g. 17, Fig. 6, not shown) and the other may be connected to all the conductors 5. The conductor 4 of one pair 4, 5, may be connected at each end to corresponding ends of the conductor 5 of the next pair and so on (Fig. 8, not shown). Each group thus formed constitutes a series of transmitters 2 and receivers 6 disposed alongside, but spaced from, the belt, the pitch of the transmitters and of the receivers being equal to the length of each group arrangement of conductors.

Title: Planar silicon-on-sapphire integrated circuits and method for producing such integrated circuits
IPC: H01L21/762
Filed: 1978-09-14
Abstract: Planar conductor-insulator-semiconductor (CIS) integrated circuits e.g. comprising complementary transistors 12, 14 built on an insulating substrate 16, such as sapphire or spinel, employ conductive polycrystalline silicon gates 24, 34. In order to provide devices having low leakage currents an oxidation temperature of less than 1000 DEG C is used to produce both the field oxide 38 and the gate oxide 26, 36. In addition, ion implantation techniques are used for doping the sources 18, 28 and drains 20, 30 of the transistors 12, 14 to provide close control over their doping concentrations. Utilization of N+ doped polycrystalline silicon gates allows phosphorus doped silicon dioxide 39 to be used as a getter, and also provides higher conductivity gates than P+ doped gates. <IMAGE>

Title: Process for the recovery of metal values from anode slimes
IPC: C22B7/00
Filed: 1979-04-11
Abstract: To extract silver from anode slimes from electrolytic copper or nickel refining that also contain selenium and/or tellurium, the silver values comprising silver compounds of selenium and/or tellurium are converted to a material containing silver in a form readily leachable in dilute nitric acid, the silver containing material, e.g. silver, silver oxide or carbonate, is leached with dilute nitric acid, and the silver is recovered from the leach solution by electrowinning. To solubilise the silver the slimes may be subjected to a caustic oxidative leach, which may be preceded by an acid pressure leach with sulphuric acid or a sulphation leach with concentrated sulphuric acid to dissolve copper, nickel and tellurium. Alternatively the slimes may be subjected to an acid oxidative pressure leach in sulphuric acid, followed by a caustic addition. Selenium and tellurium present are also recovered in an overall hydrometallurgical process. The residue from the nitric acid leach may be leached in a soluble acetate to extract lead and the residue treated to recover platinum metals and gold.

Title: Fluid flow measuring apparatus
IPC: G01F1/66
Filed: 1979-07-19
Abstract: Fluid flow measuring apparatus comprises two ultrasonic transducers (1, 2) between which an ultrasonic energy beam is transmitted through the fluid, the beam being frequency modulated (4, 5) by an audio signal, and the relationship between the frequency or phase of the received modulation signal (6, 7, 8) and that of the transmitted modulation signal gives a measure (10) of the speed of flow of the fluid. Beams of ultrasonic energy are preferably fed in two mutually opposite directions, for example by switching (3) the transducers to act alternately as transmitter and receiver, and the measurement is computed from the two relationships. An anemometer (Figure 7) comprises two such systems arranged to produce mutually perpendicular ultrasonic beams, and a computer (25) to compute wind speed (28) and direction (29) from the frequency or phase relationships. <IMAGE>

Title: Gyromagnetic detection method and apparatus
IPC: G01R33/46
Filed: 1979-08-22
Abstract: An apparatus and method for the detection particularly of explosive substances by gyromagnetic means. Suspected device 12 is subjected to a constant magnetic field from magnet 32 and to a pulsed RF magnetic field orthogonal to the constant field from coil 14. The level of the constant magnetic field and the frequency of and intervals between the pulses are varied in accordance with previously obtained results to test for the presence of selected explosive substances. In particular the magnetic field strength is chosen so that an NMR frequency of one element in a desired explosive coincides with an NQR signal of a second element therein and this cross-coupling results in an enhancement of the NMR signal if the particular explosive is present. <IMAGE>
