Abstract: 1,143,392. Multi-stage flash evaporators; desalination of sea water. APPLIED RESEARCH & ENG. Ltd. 3 March, 1966 [4 March, 1965], No. 9358/65. Heading B1B [Also in Division F1] Liquid, e.g. sea water or other brine, is submitted to distillation in a multistage flash evaporator 5, 6, 7, in which each flash chamber is associated with heat-exchange tubes 14, 15, 16 on the outer surface of which the flashed vapours are condensed thereby heating feed liquid flowing through the tubes, provision being made so that some of the vapour from an intermediate flash chamber 6 is conducted to a turbine 12 which drives an alternator 11. Turbine 12 is connected to (or forms the low pressure end of) turbine 13, the latter being supplied with steam from boiler 1. Brine, supplied through line 20, is preheated in heatexchangers 15 and 16, and is then introduced into flash chamber 6. The brine is next pumped through heat-exchanger 14 in heater 4 where the brine is further heated by steam discharged from turbine 13; and the brine is then fed into flash chamber. Part of the steam discharged from turbine 12 is passed via line 17 into the condenser casing of heat-exchanger 16, and the remainder flows to condenser 10. Distilled water is withdrawn from the system through lines 19 and 21. Brine is discharged from chamber 7 via line 22. The condensate formed in heater 4 is returned to boiler I via heater 3 which is heated by steam bled from turbine 13 by line 18. If desired, the condensate from condenser 10 may be pumped through line 19a to heater 3 and boiler 1. In a modified plant, turbine 13 is eliminated and the steam from boiler 1 is passed directly to heater 4; and, instead of driving an alternator, turbine 12 compresses vapour withdrawn from one of the flash chambers, and the compressed vapour is also supplied to heater 4. It is stated that the vapour from the intermediate distillation stage may be expanded in an internal-combustion engine (e.g. a gas turbine).

Title: Improvements in and relating to foot-operated air-pumps for pneumatic tyres, and the like
IPC: F04B33/00
Filed: 1922-04-03
Abstract: 191,322. Lumby, V. April 3, 1922. Oscillating -cylinder pumps; actuating pumps by foot power.-Oscillating cylinder pumps, in which two frame members such as a, b are hinged together as at c and normally separated by a spring, and in which a cylinder such as k is pivoted to one member and a piston such as g is pivoted to the other member, are modified to secure ready folding of the parts for storage without moving the pivot, pins bodily in slots or the like in the frame members. The trunnions q of the cylinder become coaxial with the piston pivots h when the frame members are closed, so that the piston and cylinder can be folded to lie against the folded frame. One part of the lower edge of the cylinder is cut away at p to pass the lugs during the folding action. In some cases this cut away portion may be arranged to engage the nut on the piston pivot pin to keep the cylinder and frame in the folded position. The piston and cylinder, when folded, are not under the influence of any spring pressure that would make the piston press against one side of the cylinder and thus make the cup leather wear unequally. A pivoted catch t may lock the frame members in the closed position. Clearance is provided between the cylinder walls and the frame b, and the intervening space is filled by springs coiled round the trunnions q. Preferably the trunnions are mounted in depending portions of the frame which enter recesses r<1> in the other frame when the appliance is folded.

Title: Vacuum gauge
IPC: G01L21/00
Filed: 1966-03-07
Abstract: 1,112,796. Ionization manometers. VARIAN ASSOCIATES. 7 March, 1966 [5 March, 1965], No. 9934/66. Heading H1D. An ionization gauge comprises an emitter 12, a high-voltage electron accelerator 13, a separate low-voltage electron collector 14 and an ion collector 15. The gauge functions in the presence of a magnetic field which constrains the electrons to move so that they do not strike the accelerator 13 but have a high probability of being collected by the low-voltage collector 14 which reduces the number of X-rays produced. The magnetic field may also be such that any photoelectrons emitted from ion collector 15 due to impinging stray X-rays are constrained to return to the ion collector. As shown, the cylindrical filamentary thermionic emitter 12 is disposed coaxially about one end of the elongated accelerator 13, which has a relatively small surface area, and the low-voltage collector 14 is placed coaxially about the opposite end, and all three are encompassed by coaxial tubular ion collector 15, which also forms part of the envelope. Coaxially outside the ion collector 15, and insulated from it by ring 29, is permanent or electromagnetic means 16, which produces the required field. One end of the envelope is sealed by an insulating glass or ceramic header assembly 21 through which the lead-in wires pass. The opposite end of the gauge is connected via ring 22 to vacuum flange 24 which is secured to mating flange 25 in the wall of the system whose pressure is to be measured, so that the gauge forms an evacuable appendage in the wall 26 of the system. To eliminate a residual current in the ion collector due to ion emission from the filament 12, a cylindrical electrostatic shield 30 may be provided. The accelerating electrode may be provided with an outwardly extending disc-like member to aid in drawing off electrons from the filament, Fig. 3 (not shown).
