In an evaporator wherein the liquid to be evaporated, supplied through inlet 15, is distributed as a film upon the hot inner surface 25 of wall 3 by distributor ring 14, and the film then descends the surface of walls 3 and 4 by gravity, turbulence is created in the descending film by the action of oscillatable blades 16 which are loosely connected to rotor assembly 9 by rings 17 so that the free edges 24 of the blades are immersed in the liquid film, but do not exert pressure against the walls. The heating of walls 3 and 4 is effected by heating jackets 5 and 6, which may be operated independently. The vapour formed during the evaporation passes out of the evaporator through separator 2 ; and the residual liquid flows out through outlet 8.

Title: Pneumatic logic circuits and their integrated circuits
IPC: F15C5/00
Filed: 1975-10-07
Abstract: 1502502 Valves J P PEGOURIE 7 Oct 1975 [8 Oct 1974] 41095/75 Heading F2V [Also in Division G4] A pneumatic logic circuit has a generally symmetrical structure around an axis and is symmetrical relative to a median plane normal to the axis. The circuit has a central plate 21 having an axial passage 23, a duct 25 opening into the passage and on each side of the duct a separate duct 27, 28 opening on to a respective face of the plate. On each side of the plate is a diaphragm 1, 2 formed of a flat sheet of rubber or synthetic elastomer and having on its outer surface a centring shoulder 5 provided with an axial cylindrical passage. The axial passage 23 contains a piston rod 29 having a smaller diameter than the passage and having extensions 31, 32 forming a fluid tight seal in a respective diaphragm. The inner surface of each diaphragm has a cylindrical chamber 15 of greater diameter than the axial passage 23 and a groove separated from the chamber by an annular lip which bears against a corresponding surface of the piston and which is situated to align with the outlet of a respective duct 27, 28. Each diaphragm is received in a bushing 39, 40 which contacts the centring shoulder and the outer outer surface of each diaphragm is contacted by a respective piston 33, 35 and 34, 36. Each side of the circuit is closed by a respective diaphragm 43, 44 and base 45, 46. Each base may contain a recess 47, 48 coupled to a respective duct 49, 50 used to apply control pressures P2, P1. Preferably a recess 37 is formed in each piston to receive a spring 55 used in certain embodiments of the circuit. The circuit may operate as an OR gate (Fig. 3, not shown) in which duct 25 is the output and control pressures are applied to ducts 27, 28. Pressure in either duct moves the diaphragm fed by the duct to supply pressure via passage 23 to the output. If pressure is applied to both ducts whichever diaphragm moves first overrides the other so that only one supply duct is fed to the output. As a NOT gate (Fig. 5, not shown) the chamber 47 is supplied with a control pressure, duct 25 is the output, duct 28 is coupled to exhaust and duct 27 coupled to a pressure supply. A pressure in chamber 47 causes ducts 25 and 28 to be coupled, otherwise duets 25 and 27 are coupled so that the output is the inverse of the pressure in chamber 47. As an AND circuit (Fig. 7, not shown) chamber 47 and spring 55 are used. The two control pressures or inputs are fed to ducts 28, 49, duct 27 is coupled to exhaust and duct 25 is the output. The spring is arranged so that both pressures P1 and P2 are required to overcome the spring bias to close the connection between ducts 27, 25 and connect ducts 25, 28. Fig. 8 shows a bi-stable in which chambers 47, 48 are used and in which spring 55 is reversible, i.e. as shown biases the pistons upwards but when moved beyond a central position biases the the pistons downwards.

Title: Steam traps of the free float type

Filed: 1972-09-06
Abstract: 1408034 Steam traps K FUJIWARA 6 Sept 1972 [10 Sept 1971] 41412/72 Heading F4U [Also in Division G3] In a free float type steam trap the discharge of condensate through a passage 5 from a sump 4 to an outlet port 3 is controlled by a piston valve 15 movable and extending axially within a passage 11 formed in a valve seat member 9, the valve 15 having a passage 22 therethrough leading from a pilot valve port 21 closable by the float 8 to a pressure chamber 19 bounded by a valve seat holder 13 screwed to the side wall of the trap body 1 and by a piston disc 17 secured to the valve 15. The disc 17 has one or more orifices 20 interconnecting the pressure chamber 19 and the passage 11. In operation, condensate flow through a filter 36 of spaced and superposed annular plates from an inlet 2 into the sump raises the float and allows discharge through the passage 21;into the pressure chamber with sufficient force and generation of steam by evaporation due to the elevated temperature therein to react on the disc 17. As a result the piston valve 15 is moved to open a valve port 10 in the member 9 to allow condensate to discharge through the passage 11. A small amount of condensate moves the float upwardly a sufficient distance to allow a small degree of opening of the pilot valve port 21 so that the force with which the condensate discharges into the pressure chamber 19 is too low to open the piston valve 15, but the temperature within the chamber 19 is maintained at a high level. The steam trap also includes a manually operable needle valve 26 screwed into an exhaust valve seat 25 in a passage 24 in an upper cover 6 connecting the float chamber to the outlet passage 5, and a bimetallic disc valve 31 controls the outlet of steam through a valve port 32 in the seat 25.
