Abstract: 1,157,466. Separating particles from fluids. KLOCKNER-HUMBOLDT-DUETZ A.G. 12 Aug. 1966 [13 Aug., 1965; 3 Feb., 1966; 29. April, 1966 (2)], No. 36210/66. Headings BID and B1T. Solid or liquid particles are removed from a gas stream, or solids from a liquid stream, by impingement on an array of baffles 4, which have collecting troughs 5 in their trailing edges set back behind the general plane of the leading face of the baffle. The collecting troughs 5 may extend downwards with or beyond the rest of the baffles into a sump (Fig. 1, not shown) which may be cut off from the main duct by a wall (7') (Fig. 2, not shown). Baffles may be of various sections (Figs. 4-11, not shown) and may be hollow (Figs. 14 to 16, not shown), whereby cooling or heating medium is passed therethrough to aid separation. In Figs. 12, 13 (not shown) blowers effecting the flow are located respectively upstream and downstream of the baffle array, and the baffles are accordingly set at <50 degrees or >40 degrees to the duct axis. In Figs. 17  -19 (not shown) two concentric arrays of baffles enclose a radial impeller (32), and in Fig. 20 (not shown) a circuit is illustrated whereby part of the fluid under treatment is recirculated, to ensure adequate flow through the apparatus for efficient separation when the net flow available is small. The devices may remove particles 'from gas in air conditioning of buildings and vehicles, downstream of a scrubber or cooling tower or separate dirt from the liquid effluent of a gas washing process.

Abstract: 421,923. Loom healds. HORN, W. E., Longfield, Stanningley, near Leeds. Dec. 23, 1933, No. 36239. [Class 142 (i)] To prevent the lateral movement of the rig bands, the heald strings 6 are bound or knitted to the inner side of each rig band in the usual way and the bands are then turned inside out by drawing one end of each of them through the space between alternate pairs of strings 6, so that each band 4 is within the strings. The bands are positioned in grooves 1 in the heald shafts 3, or between projections. One of each pair of strings arranged on opposite sides of the lower shaft is passed over a vertically guided lease rod 8 which may be raised for the identification of the pairs of healds when threading, and which normally rests on the portions 6<a> of the strings to tension them. The invention is applicable to cotton or worsted healds, and to wire healds.

[Also in Division B8] A process for sealing two thermoplastic, water-soluble, moisture containing films 15, 22 comprises leading the films together to form a nip, directing - a gas comprising superheated steam against at least one film to soften it and automatically control its moisture content, and pressing the films together. A film 15 which may be moistened at 18 and passed beneath a heated roller 17 is applied to the surface of a driven drum 1 provided with pockets surrounded by lands preferably covered with a rubbery material to increase the adhesion of the film thereto. Belts (not shown) hold the film edges in contact with the drum during the formation and filling of pockets formed in the film (see Division B8). A second water-soluble film 22 is applied by a roll 24 to overlie the filled pockets. Super-heated steam from a manifold 25 is directed into the nip between the roll 24 and the drum 1 and the films sealed. Steam is fed to a manifold 27, Fig. 3, provided with a heater 28. The super-heated steam then passes through a valve 30, which lowers the pressure thereof to approximately atmospheric, to the manifold 25 having nozzles 32 through which the steam issues in a cloud at low pressure. A slot-shaped orifice may replace the nozzles 32. An additional manifold 34 may heat the film as it passes around the roller 24. Specifications 991,464 and 991,466 are referred to.

Abstract: 865,674. Valves. MISSION MANUFACTURING CO. Dec. 3, 1957, No. 37584/57. Class 135. In a liquid feed control device, particularly for oilfed burners, the liquid passes through a passage 9 provided with main and auxiliary valves 12, 33 respectively operated by floats 13, 18 in a common casing 1 and so arranged that the auxiliary valve is operated to cut off the liquid supply in the event of failure of the main valve. The auxiliary float 18 is of annular form surrounding the main float 13 and is carried by spaced arms 19 between which is mounted a second arm 24 loaded by a spring 26. In the event of failure of the main valve 12 float 18 is raised and arms 19 engage a bridge piece 30 to rotate arm 24, thereby closing valve 33 through an arm 28 and also raising an indicator pin 34. Due to the action of spring 26 valve 33 remains closed and pin 34 raised if the liquid level falls, and to restore the apparatus to its normal operating condition the pin 34 must be depressed to overcome spring 26 and open valve 33. Flow through the outlet 3 is controlled by a valve in the form of a piston 47 formed on its periphery with an upwardly-tapering flow groove 52 registering with an inlet port 48. The axial position of the piston may be varied to regulate the width of the flow groove presented to port 48 by engaging a detent 81 on a rotary spindle 58 with the appropriate one of a number of notches 72, 73, ... disposed on the helical edge of a boss 71. In the lowermost position of piston 47 a spring-loaded ball 59 at its lower end closes the outlet 3.

Abstract: Solid polymers from a C3 to C5 hydrocarbon fraction containing principally a mixture of at least one conjugated alkadiene, at least one alkene and at least one alkane together with minor amounts of non-conjugated diolefin hydrocarbons isomerizable to 1-alkynes, are made by removing substantially all the diolfin hydrocarbons and any alkynes present and polymerizing the conjugated alkadiene in the presence of an organolithium catalyst and in the presence of the remaining monoolefine and alkane.  The hydrocarbon fraction is preferably a C4 hydrocarbon fraction, the conjugated alkadiene is 1,3-butadiene, and the mixture contains one butene and at least one butane, propadiene and 1,2-butadiene, and alkynes. The alkynes are removed by selective hydrogenation and the non-conjugated diolefines by fractional distillation.  The purified fraction prior to polymerization may be diluted with n-hexane and if a copolymer is desired, a comonomer such as styrene may be added.  A flow-diagram is given of a continuous method for making the polymers.
