Title: Improvements in or relating to fluid filters
IPC: B01D25/00
Filed: 1954-08-24
Abstract: 755,481. Filters. BOSCH GES., R. Aug. 24, 1954 [Aug. 25, 1953], No. 24541/54. Class 46. In a fluid filter having two spirally-wound filter strips which are interleaved and radially separated from each other, sealing and spacing connections between the strips are formed by means of threads which are disposed near to the edges of and between the strips. The filter is made by winding two strips 1 and 2 of filter paper with wool threads 4, 5, 7, 8 and corrugated distance strips 3 and 6, disposed, as shown in Fig. 2, upon a mandrel 16. The threads are drawn through tanks containing an adhesive 19. Threads 4 and 5 are thicker than threads 7 and 8 whilst the distance strip 6 is more intensely corrugated than the distance strip 3 so that when the filter is inserted into a housing 11 having an inlet 12 and outlet 13, the spiral chamber 9 in which the threads 4 and 5 and the strip. 6 are disposed is wider than the other spiral chamber 10 in which threads 7 and 8 and strip 3 are disposed. The axial opening left by the mandrel is sealed by a disc 14. Hence, fluid entering the housing 11 passes the corrugated distance strip 6 into the chamber 9, penetrates and is filtered by the strips 1 and 2, collects in the chamber 10 from whence it flows past the distance strip 3 to the outlet.

Title: Improved yarn-leasing device for warping machines
IPC: D02H13/16
Filed: 1924-10-20
Abstract: 223,607. Barber-Colman Co., (Assignees of Petersen, B. A.). Oct. 18, 1023, [Convention date]. Yarns, leasing.-In a ball warper or other warping machine the warp yarns or the ends, which pass over a roller 1 to a beam (not shown) are leased by means of a comb comprising splits or teeth 15 secured to a back 16 and furnished with three series of lugs 17, 18, and 19. The lugs 17 close alternate spaces between the teeth, but the lugs 18, 19, which are bevelled at the tops, allow threads to move downwardly in the comb spaces but thereafter prevent upward movement of these threads. The teeth may be of varying lengths to divide the comb into sections corresponding to the vertical supply columns of, say, a V-shaped creel, each column of which may contain nine supply recesses. The yarns to be leased are passed over a roller 5 supported by arms 8 fixed to a shaft and provided with handles 9 each furnished with three recesses to co-operate with spring- pressed locking-balls carried by fixed parts whereby the handles and the shaft 5 can be held in three different positions. The operative places the warp threads in the correct order in the spaces between the comb teeth and connects the threads to the beam. He then moves a rod 4 carried by arms 6 from a position where it is supported clear of the threads by lugs 14 to a position where it is supported by lugs 13 on the arms 8. The threads are then depressed by operating one of the handles 9 and the lugs 17 form a shed into which a lease rod a is introduced. This rod is then moved over the roller 1 and the threads are next raised whereupon the lugs 18, 19 form another shed into which a second lease rod b is introduced. The rods a, b are replaced by tapes, the guide-rods 4, 5 are returned to a central position wherein they hold the threads clear of the lugs 17, 18 and winding then takes place.
Patent GB-401466-A (GB)
Title: Improvements in and relating to gauges for indicating liquid depth or fluid pressure
IPC: G01F23/14
Filed: 1932-09-07
Abstract: 401,466. Pressure gauges. CARTER, B. B., 12, Carew Road, Ealing, London. Sept. 7, 1932, No. 24975. [Class 106 (ii).] In a fluid-pressure indicator, the fluid pressure in a vessel 2 determines the movement of a floating piston 10 in one limb of a U-tube, the other limb being separated from a connecting pipe 4 to the vessel, by a similar piston 6. The pipe 4 terminates in a larger pipe 3, the element 3-4 containing a volume of air or gas comprising a pressure-transmitting element between the vessel and the U-tube. The space between the pistons may contain air or gas and the pistons are made airtight by a peripheral groove of mercury 7. The indicator is corrected for tilting of the vessel, atmospheric pressure and for constancy of cubic capacity of the pressure-transmitting element when used in conjunction with a number of tanks. Compensation for tilting is provided for by a trap comprising a mercury chamber 14, Fig. 3, floating valves 16, 17 in apertures 18, 19 and passages 20 and 21 connecting the apertures with the controlling element 3 and the vessel 2 respectively. Tilting of the tank closes one of the valves, the reading of the indicator being unaffected. A similar trap may be used at the top of the tube 3. Correction for atmospheric pressure may be effected by means of a calibrated chart, a superimposed U-tube system, or a compensated barometer attachment. In one form of the U-tube system, open cylinders 9, 45, Fig. 12, are interposed between the limbs of the U-tube, each having pistons 10, 44 carrying index fingers 41, 51 respectively. Relative movement between the index 41 and its scale 42 is only due to changes in the fluid pressure of the tank. In an example of a suitable compensating barometer, an aneroid barometer box 76, Fig. 15, is connected by a beam 78 with the pistons 81, 82 of a pair of cylinders 83, 84 connected respectively across the pressuretransmitting element and U-tube of the indicating system. The fluid pressure in the tank may be read off directly by any suitable indicator actuated by the piston 10. Magnification of the movement of the latter may be effected by the use of a superimposed cylinder operating a calibrated scale through a " followup " motor. The fluid pressures in a number of tanks may be read off a single dial by the use of a rotary switch whereby any of the tanks may be put into communication with the static balance. Specifications 391,846, and 391,850, [Group XXXVII], are referred to.
