Title: Device for injecting an adjuvant into a liquid
IPC: B01J4/02
Filed: 1973-11-26
Abstract: 1447390 Mixing flowing liquids in proportions P CLOUP 26 Nov 1973 54748/73 Heading B1C In apparatus for mixing a predetermined quantity of additive into a liquid the latter is supplied under pressure to an inlet 7 in a stepped housing 1 providing two cylinders 2, 3 with a stepped piston 4a, 4b. As shown the liquid pressure moves the piston to the right and liquid in cylinder 2 is expelled through aperture 21 in the piston and outlet 8. At the same time plunger 9 draws additive into cylinder 11 from inlet 12. At the end of the piston stroke the end 34b of rod 34 strikes the cylinder wall; the rod 34 is shifted to the left taking with it the ends 33 of two springs 32 (one only being shown) controlling a twistable forked lever 26 fulcrummed at a point 29 fixed relative to the piston. The lever 26 then adopts the broken line position opening a valve 23, 24 and causing a blade 20 to close the aperture 21. Liquid can then pass from cylinder 3 to cylinder 2 through aperture 24 and the differential pressure causes piston 4 to move to the left expelling further liquid through outlet 8; at the same time additive in cylinder 11 is expelled into cylinder 43 past plunger 9. At the end of the leftward stroke rearward of the piston is again reversed by contact of the end 34a of rod 34 with the wall of cylinder 3.

Title: Pressure control valve
IPC: B60T8/50
Filed: 1972-11-28
Abstract: 1395428 Control valves; anti-skid hydraulic braking systems; valves AISIN SEIKI KK 28 Nov 1972 [2 Dec 1971] 54931/72 Headings F2F and F2V A motor vehicle anti-skid hydraulic braking system incorporates a pressure control valve 18 between a pedal operated brake control valve 26 and wheel slave cylinders 29, the valve 18 comprising a valve spool 32 axially slidable in a housing 19, first and second hydraulic chambers 33, 34 one at each end of the valve spool 32 for controlling the axial movement thereof, the chambers 33, 34 being connected by a passage 38 in the spool 32 to balance the hydraulic pressures in the chambers 33, 34 to normally maintain the spool 32 in a rest condition permitting free fluid communication between an inlet port 22 and an outlet port 23 and there being a valve flapper 52 movable upon energization of a solenoid 56 in the event of skidding to connect the chamber 34 to a drain chamber 49 whereby the spool 32 is moved rightwards to restrict fluid communication between the inle and outlet ports 22, 23. As shown, the hydraulic braking system has an engine driven pump 10 having a reservoir 11 and connected to an accumulator 13 via a pressure relief valve 15; the control valve 26 is actuable to selectively connect the inlet port 22 to the accumulator 13 or to drain. In the rest condition of the spool 32 pressure at the inlet port 22 during a brake application is transmitted to the output port via grooves 35, 37 in the spool 32 and housing 19 respectively. The passage 38 communicates with the inlet port 22 via a radial bore and communicates with chambers 33, 34 via respective nozzles 39, 43 having respective restricted orifices 40, 44. The chamber 33 is also connected to the outlet port 23 via a passage 41 in the housing 19 formed with a restricted orifice 42. Thus in the rest condition the valve spool 32 is balanced by the pressures in chambers 33, 34 and the pressure in chamber 34 is equal to the pressures in inlet and outlet ports 22, 23. If the solenoid 56 is energized, the flapper 52 which is integral with a plunger 46 is moved away from a nozzle 50 against the bias of a leaf spring 53 between pins 54, 55 to connect the chamber 34 with drain chamber 49. The spool 32 is caused to move rightwards to disconnect grooves 35, 37 and connect grooves 36, 37, groove 36 being connected to a drain port 24. This lowers the pressure in outlet port 23 but fluid pressure in the inlet port 22 is transmitted to the outlet port 23 via orifices 40, 42 and thence to groove 36. Thus the fluid pressure in the outlet port 23 does not decrease rapidly. The opening degree of nozzle 50 is determined in relation to the current in solenoid 56 and hence the fluid pressure in outlet port 23 is lowered as the current increases.

Abstract: 1366594 Dispersing gases in liquids W R GRACE & CO 28 Nov 1972 [3 Dec 1971] 54963/72 Heading B1C [Also in Division C1] A process for treating a waste liquid comprises treating a gas comprising O 2  and N 2  in a pressure swing system to remove N 2  to produce an O 2  enriched gas, passing the O 2 - enriched gas through an ozonator and contacting the liquid with the resultant O 2 -enriched gas containing 1-7% by wt. O 3 . In Fig. 2 the apparatus comprises pressure swing system 11 comprising two (or more) zeolite absorbent beds 9, 10 which are used alternately, ozonator 17 and two contact zones 20, 30. In use liquid is treated in zone 30 and then in zone 20. N 2  is removed from a gas mixture in one of the beds 9, 10 and the resultant O 2 -enriched gas is passed through ozonator 17 and line 19 to zone 20. Excess gas from zone 20 may be heated at 26 to remove any O 3  and recycled to mix with air at 1 or passed to zone 30 together with O 2 -enriched gas from system 11 via line 36. Exhaust gas from zone 30 may be vented to the atmosphere or recycled through line 27. O 2 -enriched gas may be passed directly to zone 20 via lines 16, 28 and 29. The gas mixture from line 1 may be pressurised at 2 and water vapour may be removed from the mixture by condensing at 4 and separating at 6. Gas being recycled to line 1 may be passed through scrubbing and drying means (not shown). The contact zones may comprise a number of compartments and the contacting may be carried out in a co-current or countercurrent manner. In zone 30 a biological process occurs and in zone 20, a disinfecting process.

Abstract: 1,103,180. Calendar timepieces. HAMILTON WATCH CO. Dec.15, 1966 [March 11, 1966], No. 56305/66. Heading G3T. A calendar timepiece comprises a date indicating ring 12, a spring 68, continuously wound by the timepiece dial train, a Geneva pinion 62 coupling the spring to the date indicating ring and means for periodically releasing the spring so that the spring causes the date indicating ring to be advanced to the next date. An hour wheel 16 drives a wheel 50 via a gear train 32, 36, 38, 42, 44, the wheel 50 being freely mounted on a shaft 52 secured to a bridge 54. The outer end of the spring 68 is attached to the wheel 50 whilst the inner end is attached to the lower portion of the Geneva pinion 62 which is also freely mounted on the shaft 52. The gear-wheel 38 also drives a pinion 82 which is attached by a shaft 84 to a second Geneva pinion 88 carrying a pin 90. Near midnight, the pin 90 lies between the centres of the Geneva pinion 88 and a slotted Geneva wheel 92 and in this position imparts a sudden rotation to a control disc 100 attached by a shaft 96 to the wheel 92. A cut-away segment 102 of the disc 100 releases a finger 66 attached to the Geneva pinion 62 which is then rotated by the spring 68. A pin 64 is attached to the Geneva pinion 62 and meshes with one of the slots 78 of the calendar ring 12 to advance the calendar ring one date. A circular portion 74 of the Geneva pinion 62 engages the concave surface 80 of a calendar ring tooth 76 to correctly locate the calendar ring after each date advancement. To enable manual indexing of the calendar ring, the bridge 54 is pivoted by a screw 58 and the pinion 62 is urged into engagement with the teeth 76 by a spring 106, the pinion ratcheting over the teeth during manual indexing.

Trigger pulses s produce pulses d of length #t from generator 15 which are fed to the trigger input of bi-stable 16 and inverted and fed to bi-stable 17. Unit 14 produces a direction pulse r. At the first positive edge of d during r, bi-stable 16 changes state producing the start of the marker pulse from gate 18 and sensitizing bi-stable 17 such that on the next positive edge of inverted d it also changes state terminating the marker pulse thus producing a single radial bearing marker. When r is removed the next d pulse resets the bi-stables.
