Title: Improvements in or relating to a process and apparatus for melting hydrate crystals
IPC: C02F1/26
Filed: 1962-12-03
Abstract: In a solid-hydrate process for producing potable water solid propane hydrate slush enters a first pressure vessel or melter 11 through tube 12 after having been cleansed of brine in preceding filtering and washing operations. The brine-free solid hydrate enters the first pressure vessel or melter 11 and is dispersed in the relatively warm water entering melter 11 through pipe 13.  The requisite exchange of heat energy between the water (temperature of about 8.7 DEG  C.) and the propane hydrate crystals may be further promoted by the use of agitation means such as stirrer 14 and results in the melting of the hydrate into its components, propane and potable water and at the same time cools the water admitted through pipe 13 to about 5.7 DEG C.  The compressed propane gas from melter 11 is then added to other propane gas from the hydrate reactor (not shown) and both streams of propane gas are then admitted to a second pressure vessel or condenser 22 through a connection 23.  Part of the potable water is removed from the system as product through pipe 26 while the rest of the water drained from melter 11, is forced through spray heads 32 will be in the form of small droplets to provide through dispersion thereof in the pressurized gaseous propane which is admitted to chamber 22 through pipe 23 resulting in condensation of the propane and warming up of the water.  The propane layer 33 is returned to the hydrate-forming operation while the warmed water is returned to melter 11.  The removal of liquid propane from the layer 33 is co-ordinated with the removal rate of the warm potable water through pipe 42 by the use of a level-detecting device 43.  As long as the level of water layer 34 is below the mouth of pipe 37, valve 39 remains in the open position to permit the removal of liquid propane from layer 33.  Should the level of water layer 34 rise in condenser 22 close to the mouth of pipe 37 or should the upper level of layer 33 of liquid propane diminish to the level of the mouth of pipe 37, these conditions are automatically detected by level-detecting device 43 which then actuates a solenoid or similar mechanism (not shown) closing valve 39 and preventing further removal of liquid propane. Specification 867,469 is referred to. <PICT:0965853/C1/1>

Abstract: 1,272,006. Break spinners: continuous yarn winding. T.M.M. (RESEARCH) Ltd. 8 Sept., 1970 [19 Sept., 1969], No. 46327/69. Headings DID and D1J. In a break spinning machine consecutive spinning stations S2, S3 &c. are served by two rows of winding units, consecutive winding units in each row serving alternate spinning stations. Each spinning station has two boffins 19, 19' driven by a roller 35. Yarn is wound on either bobbin and when a package is completed is transferred to the other bobbin either by an arrangement as described in Patent Specification No. 1,139,695 or a device as shown in Fig. 4. The device of Fig. 4 comprises two reciprocating yarn guides 48 and 48' carried by a rod 121 which build up the package. Yarn is transferred from one bobbin to the other by the unit S4 being traversed by means of a pneumatic ram (not shown). As the unit S4 moves across a guide pin 62' lifts the yarn from the guide 48' and carries it across to where it runs up slope S2 to engage yarn guide 48. As the yarn is carried across it is picked up by a hooked mat 63 which winds on the first few turns. A bar 65 tilts forward to allow initial threading up into slots 58 and 59 through a slot 156. Yarn between bobbins is cut by a knife (not shown) and the full package is doffed by depressing a foot pedal 42, see Fig. 3 (not shown) which pulls a wire rope (44, 44') to disengage the package from the roller 35 by tilting a mounting arm (31, 31') against a spring (33, 33'). Even package winding is ensured by dampers (47, 47').

Title: Lighting Control System.

Abstract: 1,171,915. Lighting control systems. THORN ELECTRONICS Ltd. 18 Oct., 1967 [21 Oct.. 1966], No. 47341/66. Heading H2H. [Also in Division G3] A lighting control system comprises a number (400) of dimmers 10 each controlling the brightness of a corresponding group of lamps and being controlled by a time multiplex system in which a number (400) of channels, one for each dimmer, are time divided by a master oscillator 15 and divider circuit 16 whose outputs are passed to core drivers 17 controlling a digital store 14 and to an output scanner 21 comprising a sampling matrix of AND gates which matrix decommutates the 400-channel time sequential signal from a digital-to-analogue converter 19 into 400 signals which are shaped in the dimmer drive unit 20. The brightness of each lamp group is registered in the store 14 for periodic transfer to and from a buffer store 18, which feeds the D/A converter 19 and is fed by a unit 31. The latter member raises or lowers the brightness count of groups of lamps selectable by a channel selector 13 and a number (10) of faders (only two of which 8, 9 are shown), adjustable from a centre-zero position to raise or lower the lamp brightness to maximum or minimum intensity or until the fader control member is returned to its centre-zero position. The channel selector 13 and an input scanner 22, which are described in Specification 1,171,914, co-operate with the faders to apply the analogue outputs of the latter via raise and dim output wires 23, 24 to a voltage-controlled generator 25 described in Specification 1,171,913, which converts the analogue outputs to digital signals for transmission to the store 18 through the unit 31. Each fader controls a corresponding one of the ten channels selected and alters the lamp brightness at a rate depending on the position from the centre-zero of its control member, which determines the increase or decrease in the brightness count in a predetermined time set by the generator 25. The faders may be of the type in which an analogue voltage is determined by the position of a lever carrying a magnet controlling an array of reed switches or be of the pulse-generating type, in which case the analogue to digital converters 25 is not required although the pulses require retiming by a selection circuit so that each fader controls the desired lamp group. A suitable pulse-generating type fader comprises cams closing a pair of contacts or a series of magnets passing a reed switch or switches.
