Abstract: 758,266. Gas-blast switches. LICENTIA PATENT-VERWALTUNGS-GES. Jan. 26, 1954 [Jan. 29, 1953]], No. 2343/54. Class 38(5) In a high-voltage gasblast switch having at least one tubular contact traversed axially by the gas blast an arcing electrode arranged within and firmly connected with the contact has associated with it an annular or cylindrical auxiliary electrode so arranged and dimensioned that the electric field between the switch contacts is prevented from pentrating into the tubular contact without the electrode substantially impeding the flow of gas through the contact. In the arrangement shown, the two tubular contacts 1, 2 are movable in opposite directions and the arcing electrodes 3, 4 and auxiliary electrodes 5, 6 are carried within the contacts on metallic webs 7, 8. The arcing and auxiliary electrodesare stream-lined and may have their faces exposed to arcing formed of a metal of high melting point such as tungsten or molybdenum or of an alloy of such metals.

Title: Improvements in or relating to means for facilitating the unloading of ships

IPC: B65G67/00
Filed: 1959-01-13
Abstract: 871,584. Endless bucket conveyers for unloading ships. KING Ltd., GEO. W. Jan. 12, 1960 [Jan. 23, 1959], No. 2601/59. Classes 78 (1) and 78 (4). An endless bucket conveyer for unloading a ship extends below the end of a telescopic housing 13 extending below a hollow boom 12 housing the conveyer and mounted on a carriage moving, for example, over rails 11 on the roof of a dock building. In the form shown, three pairs of sprockets 16, 17, 18 over which the bucket conveyer runs, can be run at different speeds, to increase or decrease the number of buckets between each pair of sprockets, when it is wished to lengthen or shorten the conveyer. When the conveyer is sufficiently shortened its lower end engages freelymounted sprockets or wheels (not shown) mounted in the lower end of the housing 13 so that the conveyer, as it is shortened, telescopes the housing. The boom 12 may be retractible, and the housing 13 may pivot about an axis transverse to the boom 12. The sprockets 16, 17, 18 may be controlled by push-buttons, or may be controlled automatically in response to movement of the ship with the tide. Warm air may be blown through the apparatus to prevent its freezing up. Some of the buckets may be provided with members 23 for carrying pound boards from the ship's hold to an aperture 24 in the housing 13. Alternatively each pound board may rest on a ledge formed outside one bucket, being retained at its upper'end by a downwardly-facing anglebracket carried by the bucket above. The boards are then released at the aperture 24 by a blow on their lower ends which dislodges them from the lower bracket; the blow may be effected manually or by mechanism working in synchronism with the conveyer. Each bucket may be provided with a projection, some of the projections being to one side and some to the other, to co-operate with means not shown to tip the bucket selectively on to a conveyer 21 or into a shoot 22 which discharges into the harbour; this permits the conveyer to be used for handling fish and ice simultaneously.

Abstract: 1,207,060. Electrochemical dimerization of acrylonitrile. MONSANTO CO. 22 Jan., 1968 [30 Jan., 1967], No. 3266/68. Heading C2C. [Also in Division C7] A process of removing hydrolysed polyacrylonitrile from an aqueous mixture consisting essentially of a quaternary ammonium salt, adiponitrile, acrylonitrile and hydrolysed polyacrylonitrile, is characterized by maintaining the mixture at a temperature up to 45 C. and for at least an hour (e.g. in a decanter) to form a water phase and an organic phase, the phases being separated by an interface, and withdrawing a portion of the interface as the hydrolysed polyacrylonitrile. This process is primarily suitable for improving the efficiency of the electrolytic dimerization of acrylonitrile to adiponitrile by removing the hydrolysed polyacrylonitrile by-product which if present will foul the cathode. The portion of the interface removed may be filtered to remove the hydrolysed polyacrylonitrile and the filtrate may then be passed back into the water phase. The preferred temperature of the mixture in the decanter is from 20 C. to 35 C., the desired pH from 2À5 to 7À5.

Title: Phase detector
IPC: H04N5/95
Filed: 1966-01-25
Abstract: 1,122,242. Phase stabilization. RADIO CORPORATION OF AMERICA. 25 Jan., 1966 [23 Feb., 19651, No. 3404/66. Heading H3A. An arrangement for stabilizing the phase of a reproduced tape-recorded colour television signal comprising means for developing a colour burst pulse train from the reproduced signal and for comparing it with a reference pulse train of the same frequency to derive a phase error voltage for control of an electrically variable delay line connected in series with the output of the reproducing apparatus. The colour burst train is obtained in separator 14 and applied via shaping circuit 15 to a gate 18 controlled by the output of bi-stable circuit 21 and also via a delay 16 to gating circuit 17. If on the occurrence of a pulse at the input to gate 18 the bi-stable circuit is in its first stable state the pulse passes through the gate and triggers a monostable circuit 19 which develops an output pulse of fixed duration. The delay 16 is arranged to be of slightly less than half this duration, hence the delayed pulse samples the output pulse from the monostable circuit and passes an output to one input of comparator 20. The return of the monostable circuit to its stable state switches bi-stable circuit 21 to its second state in which it blocks gate 18. Reference source 22 provides an output pulse train at the same frequency as the colour burst train and this is applied via shaping circuit 23 to a gate 24 controlled via a pair of monostable circuits 27, 25 such that on passage of a pulse through the gate the circuits are operated in turn to provide a blocking voltage to prevent the passage of the next following pulse. The output from this " divide by two arrangement triggers a saw-tooth generator developing a saw-tooth signal with a sloping leading edge extending over a period equal to the duration between every other pulse from the reference source. The return of monostable circuit 27 to its stable state also triggers bi-stable circuit 21 to its first state in which it opens gate 18. When the pulse trains are substantially in phase the arrangement operates to remove alternate pulses from the reference train and the opposite alternate pulses from the colour burst train hence the sampled pulses coincide with the mid portion of the sloping leading edge of the saw-tooth signal. Comparison of these signals in comparator 20 develops an error voltage for application to control delay line 13.
