Filed: 1923-07-03
Abstract: 220,768. Peters & Co., Ltd., G. D., and Rawlings, V. P. July 3, 1923. Fluid-pressure. - The hand release valve, and it may be also the non- return ball valve, of diaphragm cylinders for vacuum brake apparatus are located in housings on the outer side of the upwardly extending wall, and beneath the usual outwardly turned flange 3, of the cylinder bottom 2, the housings being formed integral with, or being welded to, the cylinder bottom. As shown in Figs. 1 and 3, the housing 1 is connected at 5, 7, and 6 respectively with the spaces below and above the diaphragm, and to the train pipe, and the valve cylinder 14 and its seating 11 are screwed into place in the valve chamber 4. The valve comprises a seating-ring 9 and a cup-leather 13, and its stem 18 is guided in a cover 17 and carries a diaphragm 18 to prevent ingress of atmospheric air. With this construction, the valve projects only slightly beyond the flange 3 and the outer end of the valve stem 16 does not project beyond the cylinder bottom. As shown in Fig. 4, the ball valve 20, controlling communication between the passages 26<a>, 25<a> leading respectively to the lower and upper sides of the diaphragm, may be carried in a housing 23a under the flange 3, the valve seat 23<b> being screwed into position, and the opening below it being closed by a screwed plug 27a. In Figs. 1, 3, and 4, the upper part of the cylinder has an inwardly turned flange, but when the flange is turned outwardly, the flange above the valve housing may be locally thickened to permit the continuation of the passages 7 or 25<a> through it. The ball valve may be carried by the plate 21, Fig. 1, to which the diaphragm is attached, in which case the housing 23 screws into position, and the cylinder bottom has a. tapped hole closed by a screwed plug 29, the heads 28, 30 of the housing and plug being of the same size. Registration of the passages in the valve housings with the corresponding ports in the flange of the upper portion of the cylinder may be secured by providing the ports with short lengths of tube 32. Specification 117,949, [Class 122 (i), Engine and like cylinders &c.], is referred to.

Patent GB-1145673-A (GB)
Title: Improvements in or relating to apparatus for determining salinity
IPC: G01N27/06
Filed: 1966-04-21
Abstract: 1,145,673. Measuring salinity electrically. BUZZARDS CORP. April 21, 1966 [April 22, 1965], No.17546/66. Heading G1N. A submersible salinity measuring probe Fig. 3 is lowered through the sea as a coiled cable 37 therein unwinds, the cable connecting the probe to measuring circuits on a ship and being uncoiled at its ship-mounted end at the same speed as that of the ship, the probe consisting of a lead nose 54 and a hollow tail with fins 52, an insulating tube 66 being carried in the probe with an electrode 55 mounted at its midpoint and connected to the cable 37. The water flows through the probe and the outer mass of water forms a short circuit between the ends of the tube, so that the resistive columns of water contained in the two halves of the tube are connected in parallel. One, two and three wire signalling circuits are described for connecting the probe to the measuring circuits. In the single wire system Fig. 4 (not shown) the two resistive columns (13, 14) of water in the tube 66 are connected via the line (18) to a chopper (17) supplying pulses of alternate polarity to the electrode 55 to prevent chemical polarization thereof. The chopper 17 is connected by a second chopper (24) to constant current generators (29, 30) one of which supplies nine times the current of the other. The chopper (24) operates at twice the frequency of chopper (17) and thus during each half cycle of chopper (17) the current supplied to the probe is changed by a factor of ten, by changeover of contacts (f, m) of chopper (24). When the greater current flows, Zener diodes (15, 16) connected across the resistances (13, 14) conduct and cause a fixed voltage e z  to appear across a potential divider (10, 11) so that 0À1 e z  is applied to an amplifier 21. When the smaller current flows, the Zener diodes do not conduct due to insufficient voltage across the resistances (13, 14), and this voltage is applied together with an e. m. f. of 0À1 e z  generated by a battery (E1) to the amplifier 21. The voltages are thus alternately applied to the amplifier 21, the output of which charges a capacitor (27) to the difference between them by virtue of a contact (c) of the chopper (24). The difference is amplified and drives a servomotor (28) to adjust a variable resistor (31) in the constant current circuit until this resistor represents the conductivity of the water. In the two wire system a re-balancing bridge circuit is used Fig. 6 (not shown), in which one arm contains the parallel resistive combination (13, 14) and the resistance of a line (61) connected to the electrode 55 Fig. 3, and an adjacent arm contains the second line (62) which is connected to the lead nose 54, and therefore to the short circuited ends of the columns of water. A third connection is made via the water (32, 90) to link the A. C. source (110) to the bridge diagonal. In the three wire system, a further wire replaces the connection via the water.

Filed: 1928-06-18
Abstract: 292.473. Brillo Manufacturing Co., Inc., (Assignees of Field, C.). June 18, 1927, [Convention date]. Winding or reeling machines.-Wire for making metal wool is drawn from a reel 64, Fig. 4, and wound on a reel 78 driven by an electric motor. It is lubricated in its passage by pad 104, and passes through an adjustable friction grip 94, and a tension device 110, and through straightening rollers 76. The friction grip serves to sever wire not sufficiently strong for the subsequent operations, and the ends of such wire as well as the ends of successive supply coils are welded by a suitable device 94a. The tension device 110 comprises fixed rollers 70, 72 and a sliding roller 71 pressed upward by springs 109 and provided with a scale. A yoke 199, Fig. 4, is used with bars through openings 204, 205 to interchange full and empty reels 78, 50. The Specification as open to inspection under Sect. 91 (3) (a) states also that the reel 78 is reciprocated axially on its feathered shaft 79 by screws 127, 126, Fig. 12 (Cancelled) which are continuously rotated by gears 144 thereon, gears 143, 142 mounted on one end frame 128 and a fixed gear 140. One or other of the screws is always engaged by one of the half nuts 150, 151 carried by a cross slide 153 which is connected by a bell-crank 163 to a slide 160. This is held in either end position by a pawl 172 or 176 until a rod 157 engages a stop 165 or 180 to compress springs 167 or 182 between a collar 169 or 185 on the rod and an end of 'the slide 160 and then to force back the pawl by a projection 174 or 186 so that the spring quickly reverses the half nuts. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to soft collars
IPC: A41B3/06
Filed: 1921-06-28
Abstract: 178,058. Montain, V. April 2, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Collars, lace, linen, and like; stiffeners.-Relates to stiffeners for soft collars such as ladies tulle collars, ladies' dress collars, wide collars, and detachable collars for garments and also to constructions of soft collars to take these stiffeners. Many different arrangements are described in which plates or bars are pressed apart by the action of springs or elastic, and in some constructions the plates or bars are extensible for different sizes of collars. In the construction shown in Fig. 1, the bars 1, 2 are pressed apart by blade springs 110, which, in another construction are in pairs. The bars may be connected by links 90, Fig. 3, the pivots 91 of which may be connected by an elastic strip 93 or by rubber bands engaging notches on each side of the pivots. In another construction, the lazy tong linkage is extended and there are two elastic connections. In another modification, two pairs of parallel linkage are connected by elastic, and abutments are provided on the bars to limit the movement of the links. In the construction shown in Fig. 17, the bars are provided with slotted enlargements, and the bar 1 has a button 5 capable of sliding in the slot 3 of the bar 2, which is connected to the button by a piece of elastic. The elastic 6 may, as shown, pass freely through the centre of the button and be connected to both bars. Modification of the enlarged portions may be made with stamped-up parts forming a sort of guideway. In the construction shown in Fig. 28, the bar 2 is pivoted to an enlargement on the bar 1 and is provided with a button 5 attached by elastic 6 to the bar 1 which has a slot 3 made in an enlarged portion. In a similar construction, the pivoted bar is controlled by a spring at its pivot. By arranging three sets of linkage of the construction shown in Fig. 3, joining the two bars, the arrangement is made suitable for use in making tulle collars. Three sets of linkage may be used to connect each of two pairs of bars, longitudinally adjustable. The bars may be replaced by plates cut away for lightness. The stiffeners may be inserted between the lining and outer fold of a soft collar, slits being provided in the collar for this insertion. Fig. 60 shows a collar with loops 88 for retaining the stiffeners. The loops may be arranged in the neck band or the fold of the collar, and the same applies to the slits. Other constructions of collar are described with flaps for fastening the stiffener in position, and loops may be combined with the flaps. The stiffener may be provided with holes to register with the stud-hole on the collar.

Title: A stop plug for tubular passages
IPC: F16L55/136
Filed: 1922-06-26
Abstract: 197,227. McClelland, N. E. June 26, 1922. Stopping pipes and tubes.- An expansible stopper for boiler and other tubes, of the kind comprising a number of sectorshaped wedges disposed around a central wedge, is expanded against the wall of the tube by the agency of a normally compressed spring, which is released after the stopper has been inserted in the tube. Two sets of wooden wedges 2, 3, 4, 5 and 6, 7, 8, 9 around the central metal wedge 1, as shown in section in Fig. 3, are tapered in opposite directions, and are secured in the contracted position to one another and to the wedge 1, by glue or the like, the spring 15 being held compressed between a nut 14 on the rod 19 which carries the stopper and a washer 16 bearing against one end of the wedges 6, 7, 8, 9. The rod 19 carries a stopper at each end if a double closure is desired, and is pushed through the tube until a loosely mounted ring 21 held against the end of the wedge 1 by a nut 11 drops and prevents the stopper being pulled back into the tube. A canvas sleeve 17, held at one end against the washer 16 by the spring 15 and glued at the other end to the spring, is packed with sawdust and resin, or other mixture adapted to collapse under the influence of heat, and permit a split spring band, compressed within the sleeve, to expand the canvas sleeve 17 to form a closure pad against the inside of the tube. When the stopper is in position in a leaky boiler tube, the heat melts the glue holding the wedges and releases the spring 15 which s.multaneously forces the wedges outward to form a close stopper as the wood swells by contact with the water.

Title: Method and device for transferring fluidized solids
IPC: B01J8/26
Filed: 1958-06-03
Abstract: In a process wherein finely divided solids are treated with fluidizing gases in successive beds (B, C) and the solids are continuously transferred from one chamber (10) to another (12), solids from the first chamber are discharged to the top of a downwardly flowing fluidized column (29), passed to the bottom of an upwardly flowing fluidized column (30) and discharged from the top of the latter to the second chamber; said <PICT:0880792/III/1> fluidized columns being maintained by gases compatible with the gases in each of the chambers.  The gases in the chambers are thereby prevented from mixing.  The illustrated embodiment, to which the numerals relate, shows a feature of the apparatus of the invention, viz. the provision of means to shut off the supply of fluidizing gas to said columns in dependance on a pressure change of predetermined magnitude.  In the Figure, the chambers 10 and 12 each contain two fluidized beds arranged conventionally and standpipes 29 and 30 connected by line 31 form a U-tube containing the fluidized columns of particulate solids.  Three differential pressure devices 41, 42, 43 which are responsive respectively to differences of pressure above the beds between which the solids are passed and to differences in pressure between the bottom and the top of each fluidized column, are provided and are connected respectively to pressure switches 44, 45, 46 which in turn actuate a solenoid 40.  This operates a valve 39 which alternatively opens line 38 or connects it to a vacuum line. Valves 34 and 35 for fluidizing gas and valve assembly 47, 48, 49 are thereby controlled so that when an abnormal pressure differential occurs, the gas fluidizing the column is cut off and the U-tube closed.
