Title: Desalination
IPC: C02F1/22
Filed: 1967-05-23
Abstract: The crystallizer 12 of a desalination plant comprises a container 114 (Fig. 2), a tubular baffle 110, an inlet 48 for saline water, and nozzles 106 for injecting a volatile liquid refrigerant upwardly into the interior of the baffle so as to cause the saline water and resultant ice-crystals to circulate in the manner shown by the arrows. The slurry leaves through line 50 and refrigerant vapour leaves through line 78. As shown in Fig. 1, incoming sea-water is de-aerated at 18, and divided into two streams 40, 42 which are cooled in heat exchangers 20, 22 by product water and concentrated brine respectively, the cooled streams 44, 46 leaving the heat exchangers being re-combined and supplied to crystallizer 12. The slurry from line 50 passes to a washer/separator column 14 in which concentrated brine is removed at 122, wash water is sprayed from 124 and an endless belt scraper discharges ice through a shoot 52 to a melter/condenser 16. Product water from the latter passes through line 56, heat exchanger 20, line 58 and refrigerant removing devices 26, 30. Refrigerant vapour (n-butane) from line 78 is supplied by compressor 32 to the melter/ condenser 16 from which uncondensed refrigerant passes through line 82 to a further compressor 34. The compressed gas is condensed in heat exchanger 24 by brine from heat exchanger 22, the brine being subsequently discharged via a butane remover 28. Butane from removers 26, 28 passes to compressor 35 which discharges to the inlet of compressor 32.

Title: Arrangement for imprinting and punching cards
IPC: G06K1/04
Filed: 1967-11-23
Abstract: Card feed.-The apparatus disclosed in Specification 1,198,331, is provided with a collecting station 230, Fig. 13, for the cards 64, said station being located between the printing couple 184, 218, Fig. 11, and a punching machine (126), Fig. 2 (not shown). Cards are transferred from the station 230 to the machine (126) in dependence on the punching by the machine (126) of data scanned on a preceding card or cards. Each printed card is removed from the printing couple by a stripper 225 and fed by levers 222 and wires 223 to feed rollers 207, 214, slide rails 226, 227 being provided to facilitate the card transport. The rollers 207, 214 feed the cards to the collecting station 230 which is in the form of a receiving box. Before each card reaches the final set of feed rollers it closes a switch 107, Fig. 13, so that a magnet 115 is energized causing a lever 257 to rock via a pawl 239 and a ratchet wheel 241. The movement of the lever 257 raises card-holding means 262 whereby at least one card at the station 230 is moved on to a card-transport table 280 by a transport roller 248. The roller 248 is rotated from a shaft 242 by belts 243, 244 and 247 and is supported by levers which are rotated by a cam device to cause the roller to engage the card or cards. The table is bounded by plates 265, 266 and locking pins 271 are rocked clear on a shaft 270 to allow access to the table for the cards. The magnet 115 is de-energized when the card passes beyond the switch 107. Card delivery.-The punched and printed cards are delivered to a box (279), Figs. 2 and 16 (not shown), by apparatus including a feed table 280, Fig. 15, and a transport wheel 282 driven by the punching apparatus. Each card is engaged around the table 280 by rollers 288 on shafts 285-287, a switch 142 being opened as the card runs over a plate 292 and a guide plate 297 being provided around part of the roller periphery. Each card passes from the table and is introduced through a guide slot 291 so that it closes a switch 325 and energizes a magnet 326 so that a roller 328 is moved to push the card into contact with a belt (320), Fig. 16 (not shown). Drive rollers 301, 302 or 303, 304 are rotated by a motor 307 via a worm wheel 305 and the roller 301 is rotated by a belt (310). A further belt (311) co-operates with the belt (320) to deliver the card to the box (279). The recording by a punching machine is optional and may be replaced by mechanical, electrical, optical or magnetic means. Set-off prevention.-At least one infra-red heater 366, Fig. 11, is provided to dry the freshly printed cards. The heater may be assisted by a current of air and is operated intermittently while each card is stationary or is passing through. The feed device for the data carrier is identical with that disclosed in Specification 1,198,332 and the punching apparatus is identical with that disclosed in Specification 1,198,332.

Title: Apparatus for pneumatically stopping spindle assemblies of a textile yarn processing machine in a predetermined position
IPC: D01H1/241
Filed: 1972-11-29
Abstract: An apparatus for automatically stopping rotation of a spindle assembly of a textile yarn processing machine in a predetermined position and which includes provision for facilitating the threading of a yarn end through the hollow axle of the spindle assembly. The apparatus comprises brake means including a brake shoe mounted on a reciprocating piston and a braking surface on the whorl of the spindle for initially stopping rotation of the spindle, pneumatic control means for directing pressurized air between the brake shoe and braking surface to thereby at least partially release the brake means and permit the spindle to slowly rotate after it has been initially stopped, and means including an aperture in the braking surface of the spindle whorl for carrying away the air directed between the brake shoe and brake surface to thereby re-establish the brake means to stop the spindle in a predetermined position wherein the aperture is aligned with the brake shoe. Concurrently, the air entering the aperture in the braking surface is directed outwardly through an outwardly directed channel in the spindle disc and which communicates with the hollow axle to thereby draw air through the hollow axle and thus facilitate the threading of the yarn end therethrough. The above braking and pneumatic control means may be positioned at each spindle of the machine, or they may be mounted on a movable carriage which may be brought to a spindle requiring servicing.

Patent ES-414582-A1 (ES)
Title: Hammer breaker for breaking-up bulky refuse material
IPC: B02C13/282
Filed: 1973-05-09
Abstract: A hammer breaker for breaking up bulky refuse material comprises a rotor having a number of breaking hammers attached to it about its periphery, the rotor being rotatably mounted in a housing having a lower open end and a part above the rotor which forms a supply hopper. The part above the rotor includes two opposite side walls which extend in the direction of the axis of rotation of the rotor and which diverge away from each other. One of these two side walls which is adjacent the part of the rotor where the hammers are moving downwardly as the rotor rotates has one or more counter-tools fixed to it and this side wall is hinged to the remainder of the housing to enable it to be moved to move the counter-tool or tools towards and away from the rotor axis and a mechanism which preferably includes a toggle linkage and a hydraulic ram is provided for moving the hinged side wall inwards and outwards. The hinge axis of the hinged side wall, which is parallel to the axis of rotation of the rotor is at substantially the same level as the axis of rotation of the rotor and the side wall extends upwards from the hinged axis to above the uppermost point on the path of rotation of the hammers as the rotor rotates. Movement of the side wall by its moving mechanism towards or away from the rotor ensures that if the bulky refuse material supplied to the housing bridges over the rotor, the bridge collapses and the material is fed again to the rotor.
