Patent GB-1050062-A (GB)
IPC: F16T1/26
Abstract: 1,050,062. Steam traps. K. ZANGL. March 19, 1965 [March 24, 1964], No. 11754/65. Heading F4U. A steam trap for a vulcanizing press has a float 14 with a needle valve 13 controlling an outlet 11, and a ball valve 23 in a tubular housing 18 having side openings 22 and a mouth 19 whereby large quantities of air and condensate can flow rapidly to the outlet pipe 6 without causing the valve 23 to close. The valve housing 18 is screwed into a partition 7 which carries a pipe 9 extending into the float 14 around the stem 12 of the needle valve 13. Condensate entering at 3 fills the trap 4 and overflows into the cup-shaped float 14 to lower the float, opening the valve 11. The ball 23 lies on an opening 21 at the base of the valve housing 18 and the condensate and air pass rapidly through the passages 22 and 19 to the outlet pipe 6. Steam arriving at the valve openings 22 becomes throttled causing a difference of pressure between the main chamber 4 and the interior of the valve housing 18, thus raising the ball 23 to close the valve mouth 19, preventing escape of the steam. The steam pressure then forces the condensate in the cup 14 up through the pipe 9 and passage 11 to the outlet 6, so that the cup rises to close the passage 11. When sufficient further condensate overflows into the cup 14 the cup descends to open the passage 11 again and the action is repeated. An opening 29 at the top of the pipe 9 allows air to be vented when the valve 13 is open. A manually operated valve 27 allows direct purging of air from the trap.

Abstract: 1,232,988. Pattern analysis using cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. 3 Sept., 1968 [1 Sept., 1967], No. 40001/67. Heading G4H. A pattern analysing device comprises a cathode-ray tube 1 with a phosphor screen 2, means 10, 11 for projecting an image of the pattern on to the screen, scanning means for causing the beam to trace a raster on the screen, a pointer 12 which is manually positioned to indicate a point of interest on the pattern, the pointer being sensitive to the passage of the beam, to produce an output signal which is used to indicate the position of the point on the raster. The pattern may be a fingerprint, the pointer 12 being used to indicate the positions of important features such as the points of convergence of ridges. Scan deflection signals are obtained from counters 4 and 5 receiving pulses from clock 6. The outputs of the counters are applied via digital-to-analogue converters 7, 8 to deflection coils 3. The outputs of the counters are also applied to gates 14, 15 which are enabled by the pulse given by pointer 12 when the beam crosses its end. This pulse opens the gates to pass the X and Y co-ordinates of the pointer as indicated by the instantaneous values in the counters 4 and 5. The output from the pointer may be applied over line 18 to brighten up the beam at the point indicated by the pointer so that this point can be seen more exactly. A connection 19 from the computer may brighten up points previously indicated by the pointer and recorded. The outputs from gates 14, 15 may be inhibited until the operator is satisfied that the pointer is in the correct position. In a second form the apparatus is used in two steps. The first is similar to that described and in the second, the lamps 10 illuminating the pattern 9 are switched off, the pattern being illuminated by the raster on the face of the screen 2. A photomultiplier receives reflected light and passes the signal to a computer which automatically counts the numbers of ridges between previously recorded points.

Abstract: 1,258,271. Gas pump driven by compressed gas motor. AMERICAN METER CO. Jan. 1, 1969 [Sept. 17, 1968], No.30/69. Headings F1M and F1N. A gas sample is collected from a main 13 by a pumping plunger 29 reciprocated in a cylinder 31 by a diaphragm 41 permanently pressurized on its underside, the chamber 27 above the diaphragm being alternately pressurized and exhausted at a controlled rate so that a representative sample is collected. Gas admitted to the chamber 27 through a connection 18 enters the cylinder 31 through a hole in the plunger, the hole being closed by an annular seal 30 during the compression stroke. The compressed gas opens a spring-loaded lift valve 33 and flows into a line 14. The rate at which the chamber 27 is alternately pressurized and exhausted is controlled by a valve 11 which is either pneumatically operated, as shown, or solenoid operated, Fig. 7 (not shown). The valve 11 is responsive to the pressure in a line 20 connected by a passage 61 to a branch main 17. If pressure is lost in the line 20, a piston 65, 66 lifts thereby to connect the connection 18 to a vent 68 instead of to the mains branch 17. Exhaustion of the line 20 may occur after a predetermined amount of gas has passed through the main 13 as detected by a meter (100, 103), Figs. 5 and 6 (not shown). Alternatively, the exhaustion may be controlled by a timing head 12 comprising a shuttle valve 82 controlling a vent 80. The shuttle is moved by a diaphragm 74 subjected on its upper side to the mains pressure. When the piston 29 performs a compression stroke, a spring 76 lifts the diaphragm at a rate determined by the setting of a needle valve 90 in a by-pass 91, 92, 93 between opposite sides of the diaphragm.
