Title: Improvements in or relating to multiple-effect evaporators
Inventor: STARMER ROY
IPC: B01D1/26
Filed: 1961-08-24
Abstract: 1, 040, 042. Multiple-effect distillation apparatus; desalination of water. RICHARDSONS WESTGARTH & CO. Ltd. Aug. 17, 1962 [Aug. 24, 1961], Nos. 30563/61 and 968/62. Heading B1B. A multiple-effect evaporator, which may be used for producing distilled water from saline water, comprises a vessel 10 divided into compartments 14 by metal partitions 12, each compartment being maintained at a lower pressure than the compartment immediately beneath it, wherein the saline water is distributed by sprays 34 on to one side of each partition so as to form a moving liquid-film thereon. The bottom compartment is heated by live steam or hot combustion gases introduced through line 26; and the top compartment is cooled by a cooling liquid introduced through line 30. The vapour generated from the saline water flowing over the upper surface of the partition 12 in the lowest compartment 14 condenses on the lower surface of the partition above, and thus heats the film of saline water flowing in the compartment above. This same principle also applies in the higher compartments (except the top compartment). The condensate formed on the lower surface of each partition flows into troughs 20, and is withdrawn through lines 22. Unevaporated brine reaching the lower part of the partitions is withdrawn through pipes 18. Each compartment may be supplied in parallel with saline water, or the saline water may flow in series through the compartments. An apparatus is also described wherein the compartments are separated by tubular heatexchange units, the brine from one compartment flowing down the tubes into the next compartment, and the vapour formed is used as the heating medium on the outside surface of the tubes. Each tube possesses a constriction which causes flashing of part of the water into vapour as the brine flows through it. A portion of the vapour generated in each compartment may be withdrawn and compressed, and the compressed vapour may be used as heating-medium in the first compartment.

Title: Improvements in disc brakes
Inventor: EDWARDS GORDON JOHN
IPC: F16D65/14
Filed: 1963-09-23
Abstract: 1,040,146. Disc brakes. GIRLING Ltd., & TRACTOR RESEARCH Ltd. Sept. 10, 1964 [Sept. 23, 1963], No. 31483/63. Heading F2E. A disc brake of the self-energizing type in which stationary surfaces 13, 14 and rotating surfaces 12, Fig. 2 (not shown), are frictionally engaged by axial separation of two annular pressure plates 15, 16 having balls or rollers in opposed inclined recesses, is characterized in that angular movement of the plates to initiate brake application is effected by rotation of a cam 18 located between opposed lugs 23, 24 on the plates and carried on transversely floating shaft 19 thereby permitting the cam to follow lug movements both as the friction surfaces wear and on reverse braking. On rotation of the cam, plates 15 and 16 separate and are carried round with the friction discs 10, 11 until one of the plates, depending on disc rotation, abuts stop 17. Cam 18 has its effective centre offset from the axis of the shaft which is rotatable and which can move circumferentially and radially with respect to the brake axis. Due to said offset; the mean position of the points of engagement of the cam and parallel lug surfaces 21, 22 moves outwards as the friction surfaces wear. Moreover, whether the effective centre of the cam is offset or not, relative rotation between the cam and the lugs takes place when changing from forward to reverse braking or vice versa as circumferential movement of plates and cam relative to the brake axis occurs without rotation of the shaft 19. This tends to cause locking of the cam. To maintain this " mean position " constant and to avoid the tendency of the cam to lock between the lugs on changing from forward to reverse braking, the shaft may be guided radially inwards as it moves circumferentially. In Fig. 3 (not shown), the shaft is guided in a kidney-shaped slot 27 formed in a fixed member. The abutment surfaces 28, 29 of the lugs diverge radially outwards, and the cam is correspondingly tapered. Thus, on changing from forward braking, wherein plate 16 abuts stop 17, to reverse braking, both plates rotate to abut plate 15 against said stop, said rotation moving the cam and shaft radially outwardly with respect to the brake axis as well as circumferentially whereby firstly the mean position of the points of contact of the cam with the lugs is maintained constant, and secondly, the cam is moved outwardly to a position where the lugs are more widely spaced to reduce the tendency of the cam to lock.
