Title: Improvements in or relating to clutches
IPC: F16D43/12
Filed: 1955-12-13
Abstract: 801,041. Centrifugal clutches. RANSOMES, SIMS & JEFFERIES, Ltd.; and PLUMB, A. B. April 25, 1956 [Dec. 13, 1955], No. 35802/55. Class 80 (2). A centrifugal friction clutch where weights carried on one of the clutch members force the clutch members together under centrifugal force has manual means for moving the weights axially to disengage the clutch. An engine shaft 10 carries rigid therewith a front plate 2 to which is secured, through a band 4 and studs 5, a rear plate 3 having a pulley 8 mounted thereon. The bore 23 of the pulley 8 forms a bearing for the bars 19 attached at its rear end 'to a withdrawal collar 44 and at its front end to a substantially triangular withdrawal plate 48 whose apices slide on the studs 5 under the engaging pressure of springs 50. Midway along the sides of the plate 48 are radially slotted lugs 51 carrying spindles 53 on each of which are mounted a roller 55 and two weights 54. The rollers 55 bear on bell-crank levers 57 pivoted on lugs 59 projecting from an annular ring 46 slidable on the studs 5 against the action of springs 47 to frictionally engage a friction disc 42 between the ring 46 and the front plate 2. The friction disc 42 is rigid with a sleeve 36 journalled on a flange 38 secured to the plate 1, and is coupled to a boss 25 through a series of link-plates 32 and rubber or like flexible blocks 31 to provide a flexible coupling. The boss 25 is splined to the driven shaft 18. In the dis-  engaged position the plate 48 is moved rearwards such that the spindles 53 of the centrifugal weights are radially aligned with the fulcra 58 of the bell-crank levers and thus no centrifugal face will be transmitted to the bell-crank levers. Axial movement of the plate 48 forwards allows the rollers 55 to move along the bell-crank levers and pivot them about the fulcra 58 until the arms 60 abut adjusting screws 62, and thus urge the ring 46 to engage the clutch.

Title: Multiple effect multisection flash evaporator
IPC: B01D1/26
Filed: 1969-07-16
Abstract: 1,255,676. Evaporators, multi-stage flash type; desalination of water. HITACHI Ltd. 16 July, 1969 [19 July, 1968], No. 35916/69. Heading B1B. Desalinated water is produced by evaporation of water from brine, supplied through line 113, and condensation of the vapour while passing the brine through an apparatus comprising a heater 11 and a plurality of sections each containing a series of flash evaporator chambers separated by partitions 10, additional heaters 12 and 13 being connected between the sections, additional brine being supplied through lines 111 and 11,2 as shown. The heaters may be supplied with steam from a thermal or atomic power station. The vapours are condensed on condenser tubing extending through upper chambers within the sections, and the condensate (i.e. desalinated water) is withdrawn from the system through valve 123. The first section is divided into a heat recovery section 21 and a heat dissipation section 31; and the second and third sections are each divided in a similar manner. With valves 182 and 192 closed, sea water is supplied to the apparatus through line 113 and is pumped through the condenser tubing 83 of the third section. Additional sea water, at a lower temperature, is introduced through line 112 and mixes with the sea water from tubing 83, the combined stream passing through the condenser tubing 82 of the second section. The sea water leaving tubing 82 is mixed with additional sea water, introduced through line 111, and the stream then flows through the condenser tubing 81 of the first section. After leaving tubing 81, the sea water is mixed at point m 1  with some of the brine which has been pumped through condenser tubing 91a from the last flash chamber of the first section, and the mixture then flows through heater 11 into the initial flash chamber of the first section. The non-recirculated portion of the brine from the last flash chamber of the first section is mixed at point m 2  with recirculated brine from the last flash chamber of the second section, and the mixture is passed through heater 12 into the first flash chamber of the second section. This recirculated brine of the second section is forced by pump 42 through the condenser tubing 92a extending through the heat recovery section 22 of the second section, and through the condenser tubing 92b extending through the heat dissipation section 31 of the first section. Some of the brine leaving the last flash chamber of the second section is mixed at point m 3  with brine recirculated from the last flash chamber of the third section; and the mixture is passed through heater 13 into the first flash chamber of the third section. Brine is discharged from the system through line 103. Air and other gases are vented from the condenser chambers by pipes 50 disposed in close proximity to the condenser tubing. If the quantity of available heating steam becomes reduced, the first section may be shut off by closing valves 181, 183, 171 and opening valve 182. The first section can then be descaled, if necessary.
