Filed: 1975-08-06
Abstract: 1517575 Steam turbine plant HITACHI Ltd 6 Aug 1975 [9 Aug 1974] 32948/75 Heading F1T In a steam turbine plant including a turbine 20 from which steam is extracted to heat a boiler feed water heater 60, malfunction of the heater is detected by an increase in the drain level 32 therein, and is effective to decrease the supply of steam to the turbine and to cut-off the extraction of steam from the turbine to the heater 60. As shown, a sensor 51 detects the increase of drain level to a first abnormal level, and is effective to provide a signal to an audible and/or optical alarm 40 and to a one-way valve 11. When the drain level reaches a second predetermined level, sensor 52 is effective on AND gate 41 which provides a signal to runback circuit 42 controlling a motor 43 of the main turbine throttle valve 10 to close it by a predetermined amount. When this closure is detected at 44, or after a predetermined time lag, an AND gate 45 produces a signal provided to an OR gate 46 which is effective to close a valve 12 in the steam extraction pipe between the turbine and preheater, and to close cut-off valves 13, 14 and open a by-pass valve 15 of the pre-heater. Should the drain level reach a third predetermined level before the motor 43 has closed the valve 10 by the predetermined amount, a sensor 53 provides a signal to AND gate 48 which produces a signal for OR gate 46 to close valves 12, 13, 14 and open valve 15. More than one pre-heater may be provided, Fig. 1, (not shown), each of which may provide a signal to the runback circuit 42 to indicate malfunction. A de-aerator (7) may be provided.

Title: Channel search and selection system for broadcast receive
IPC: H03J5/02
Filed: 1975-08-08
Abstract: 1503797 Channel seeking and selecting circuits for receivers TEXAS INSTRUMENTS Inc 8 Aug 1975 33167/75 Heading H3Q In a channel search and selecting system having an input device 17, 20 for introducing and storing a number associate with a received channel for comparison in a comparator 23 with a count from a counter 14, non coincidence from the comparator causes a sweep circuit 28 to vary the frequency of a heterodyne oscillator 1a, the counter counts the output signals of a multi-resonant filter 9 which provides an output when an input signal frequency from the output of the oscillator corresponds to a received channel and when the received channel tuned to by the oscillator corresponds to the stored number selected by the input device a coincidence signal is obtained from the comparator to arrest the sweep circuit. As disclosed a band switch 25 switches the tuning circuit 1 to the desired band and the filter 9, which can be a surface acoustic wave filter, to process the desired band. The contents of an addressed store location corresponding to selection of a channel by a keyboard 17 is obtained at 21 for comparison in the comparator 22 with the count of the counter 14 so as to stop the sweep when coincidence is obtained. The output from the filter 9 is shaped by a pulse shaper 12. To programme a store 20 the first channel number is selected by the keyboard 17. This resets the counter 14 and the sweep circuit 28. Operating a search switch 30 starts the tuning sweep of varactor diode oscillator 1a and when a television channel is received the video signal 5 applied to a discriminator 34 provides an AFC voltage at 33 to hold the output of the sweep circuit 28 constant. A signal identification circuit 36 investigates sync, sound carrier and AGC signals to determine if the received TV signal is of sufficient strength. If it is not the circuit 36 reactivates the switch 30 to recommence the sweep of sweep circuit 28. If the received signal is of sufficient strength the circuit 36 does not reactivate the switch 30 and the count corresponding to the received channel is passed via 22 and 38 to the addressed location of the store 20. Further channels can be stored in the store 20 by similar operation of the keyboard and search switch. A display 37 is provided for the channel number. The circuit arrangement described can be in integrated circuit form.

Title: Improvements in and relating to the production of salts of substituted dithiocarbamic acids and to the treatment of gaseous, vaporous and liquid materials, particularly hydrocarbon materials containing carbon disulphide
IPC: B01D53/48
Filed: 1945-12-07
Abstract: Carbon bisulphide is removed from liquid, vaporous or gaseous hydrocarbon material containing it by contacting the material with a primary amine of a cyclic paraffin, e.g. cyclohexylamine, or a carbamate thereof to form a salt of the cylic paraffin dithiocarbamic acid, removing the latter and decomposing it with a mineral acid to recover the carbon bisulphide and to obtain the mineral acid salt of the cyclic paraffin amine from which the amine may be recovered.  A portion of the amine may be replaced by a strong mineral alkali or a strong organic base such as alphapipecoline.  The carbon bisulphide may be recovered by distillation and the amine may be recovered, and the organic base too if present, by separation or by steam distillation. Specifications 467,581, 570,294 and 572,690 are referred to.ALSO:In the removal of carbon bisulphide from liquid, vaporous or gaseous hydrocarbon material containing it (see Group III), the material is contacted with a primary amine of a cyclic paraffin, e.g. cyclohexylamine, or a carbamate thereof to form a salt of the cyclic paraffin dithiocarbamic acid.  A proportion of the amine may be replaced by a strong mineral alkali or a strong organic base such as alphapipecoline.  Carbon bisulphide reacts with (a) cyclohexylamine to form cyclohexylamine cyclohexyldithiocarbamate, (b) sodium hydroxide and cyclohexylamine to form sodium cyclohexyldithiocarbamate, and (c) pipercoline and cyclohexylamine to form the pipecoline salt of cyclohexyldithiocarbamic acid. Cyclohexylamine cyclohexylcarbamate, which may be used instead of the amine, may be prepared by passing dry carbon dioxide into cyclohexylamine until no more is absorbed.  During the reactions with carbon bisulphide, side reactions occur in which a little of the thiourea derivative of the cyclic paraffin is produced, e.g. C6H11NH.CS.NH.C6H11.  Specifications 467,581, 570,294 and 572,690 are referred to.

Abstract: 1,189,994. Stretching natural fibres. I.W.S. NOMINEE CO. Ltd. 19 July, 1967 [22 July, 1966], No. 33171/66. Headings D1F, D1N and D1W. A sliver; roving, yarn, tow, or continuous filaments of natural fibres, particularly a wool or cotton sliver, is moistened and then stretched by anchoring it across its width at a plurality of anchorage points along its length to a carrier which advances the sliver &c., and, as the carrier advances, increasing the length of the sliver path between adjacent anchorage points the fibres being then set in the presence of moisture. As described a wool sliver is anchored either between top and bottom sets of fallers. advanced by conveyors of increasing pitch, or between pairs of gripper elements on top and bottom conveyors either with alternate pairs of gripper elements being displaced laterally with respect to the other pairs by cam surfaces as the conveyors advance or with cam followers spring mounted on one conveyor between the gripper elements being displaced to stretch the sliver held by adjacent pairs of gripper elements. The treatment with moisture, e.g. steam, can be carried out before the fibres reach, the carrier or when the assembly has been anchored but before being stretched. The sliver is set by being steamed and then dried either while on the conveyor or directly thereafter. The stretched fibres may be mixed with unstretched fibres to form, a yarn which is then subjected to a shrinkage treatment to render the yarn bulky. Mixing will not be necessary if depending on the distance between adjacent anchorage points not all the fibres in the sliver have been stretched. In one example stretched and unstretched wool slivers were passed through four intersector gills, a spindle gill, a draw box, a roving and then a spinning frame.

Abstract: 1516305 Lawn - mowers WOLSELEY WEBB Ltd 17 Oct 1975 [27 July 1974] 33297/74 Heading A1F The throw plate 11 of a cylinder-type lawn-mower has associated therewith a device 1 provided with a plurality of vanes 5 for counteracting the tendency of the helical cutter blades to throw the grass cuttings to one side of the grass box. Each vane is set at a different angle of inclination relative to the longitudinal axis of the lawn-mower so as to direct cuttings towards the side of the mower opposite to that to which the cutting cylinder 3 tends to throw the grass cuttings. The angle of inclination of the vanes increases progressively from one end of the device to the other and is greatest at the end to which the cutting cylinder tends to direct the grass, thus ensuring that the cuttings are directed into the grass box. The device may be an integral moulding and may be secured to the throw plate 11 by screws 10, or may be formed integrally with the throw plate. Alternatively, vane assemblies, comprising pairs of vanes of inverted channel form, are mounted through holes in a baffle plate by studs and nuts which allows the angle of inclination of each vane assembly to be varied to adjust the direction of throw to correspond with the condition of the grass being cut.
