Title: Improvements in or relating to means for after-treating fresh-spun artificial silk filaments in continuous operation
IPC: D01D10/04
Filed: 1950-05-05
Abstract: <PICT:0701313/IV (a)/1> <PICT:0701313/IV (a)/2> Apparatus for the after-treatment of freshly-spun artificial filaments in continuous operation comprises a plurality of tubular after-treatment conduits and means for maintaining a flow of after-treatment liquid through the conduits, the arrangement being such as to cause the filaments to be passed through the conduits p  by the action of the flow of after-treatment liquid without the use of mechanically driven forwarding rollers and the conduits being provided with enlargements adapted to cause the filament bundle to open and close repeatedly along the conduit thereby reducing the time required for the treatment.  As shown (Fig. 1), filaments spun at 1 are passed successively through liquid after treating zones I-IV.  In each zone the filaments are passed from a basin 4 along with treating liquid through a helically coiled pipe 5 provided with enlargements (not shown) into another basin 9.  A jet pump 6 serves to draw the liquid and also the filaments through the pipe.  Liquid is fed to the jet pump from a sump 10 and circulation of the liquid from basin 9 to basin 4 is effected through sump 10 and a pump 12.  Drying of the filaments is similarly effected by passing them with drying air through a pipe 18.  An injector 17, fan 20 and heater 21 are provided to circulate and heat the air.  Instead of air, drying may similarly be effected by a dehydrating liquid or a non-hygroscopic heated liquid.  The jet pump of each zone may be positioned at the other end of pipe 5, and the pipe 5 may be straight instead of coiled. Instead of a jet pump 6 a vacuum or suction chamber may be employed.  In a modification (Fig. 9) liquid is cycled by an ejector 6a from and back into each tank 4a through a pipe 5a provided with enlargements (not shown), and with a branch port 5c through which the filaments, carried along with the liquid, are withdrawn for treatment in the next zone.  The outlet 5d of each pipe is provided with a throttling member 28 for the purpose of initially threading the filaments through the entire system.

Abstract: 114,564. Collier, A. T. Aug. 8, 1917. Tone-arms; tone-arm joints; horns, arranging; sound-boxes, mounting.-Comprises several arrangements of double tone-arms communicating at their outer ends with the opposite sides of a sound-box diaphragm and at their inner ends with the same or separate enclosed or external horns. As shown in elevation in Fig. 3 and in plan in Fig. 4, the tone-arms A, B are bent downwardly at their outer ends forming vertical pivotal joints p with the upwardly-bent sound-box outlets a. The inner ends of the tone-arms may be upwardly directed to communicate with external horns E as shown, or may be bent downwardly towards the necks of enclosed horns. The weight of the tone-arms may be partially supported by a spring t connected at one end to a rod q fixed to the pivot pin x, and at the other end to the tonearm. In another form, shown in Fig. 5, an external horn E and an internal horn D are used, the pivots of the tone-arms A, B being in vertical alinement. In order to allow the sound-box C to be lifted, an elbow-piece b connected to one outlet of the sound-box has a telescopic connexion with the upper tone-arm B. Alternatively, the tone-arms may be arranged to lift with a parallel motion, being each connected to the sound-box by an horizontal pivotal joint. In another modification employing external and internal horns, the tone-arm pivots are not in vertical alinement. In the form shown in Fig. 11, the sound-box C has an horizontal pivotal connexion a<2> to one tonearm A, and on the other side carries pins m which rest at the bottom of slots k in an open-topped socket h communicating with the second tonearm B. Whilst playing, the tone-arms move with a parallel movement as in the apparatus shown in Figs. 3 and 4, while the sound-box is lifted by turning it about the pivot a<2>. The sound-box may have a pin-and-slot connexion such as m, k to both tone-arms. The two tone-arms A, B may be replaced by a single bifurcated tone-arm.

Patent GB-751531-A (GB)
Title: Improvements in an homogenizing apparatus
IPC: F16K1/38
Filed: 1954-04-21
Abstract: <PICT:0751531/III/1> In an apparatus of the type described in Specification 549,575, wherein a mixture to be homogenized is passed through a matted mass of resilient springy material such as steel wire, the mass includes a portion in the shape of a frustum of a modified cone in which the curved surface is also concave, said portion extending into a portion of a retaining passageway conforming in shape with the concave surface of the mass.  In the illustrated embodiment, see Fig. 1, the mass 13 fits into the conforming passageway 12c, and extends into the entrance 12b to said passageway so that should the mass rise due to an increase in pressure in the liquid entering from below, said liquid will still have to traverse the mass.  The porosty of the mass preferably decreases from the small cross-section end of the mass to a head portion at the other end. The compression block 14 completely overlies this head portion which may be annular or disc-shaped, and liquid is thus forced outwardly into the annular channel 23 before passing through the flutes 24 in said block, and through section 12d of the passageway to an outlet port.
Patent GB-1408993-A (GB)
Title: Two-position liquid level controller
IPC: G05D7/03
Filed: 1973-03-09
Abstract: 1408993 Sewerage systems JOHNSON SERVICE CO 9 March 1973 11493/73 Heading E1C [Also in Divisions B8 and G3] A two-position liquid level controller actuating a discharge control valve 4 mounted in a flow-line 2 comprises a static pressure sensor 6 which upon sensing a pressure in line 2 corresponding to a predetermined liquid level in storage device 5 causes timing apparatus 7 to actuate valve 4 to establish flow through line 2 for a predetermined period. As shown the controller is applied to a vacuum operated sewage collection system having a standpipe 5 upstream of pressure sensor 6. The latter comprises a snap-action diaphragm 13 subject on its lower face to pressure in line 2 and cooperating on its upper face with a leak-off orifice 16 disposed in chamber 17 connected to atmosphere via filter 18. The position of orifice 16 relative to diaphragm 13 can be adjusted by a threaded nut 20. Orifice 16 is connected via signal line 21, restriction 22, constant vacuum regulator 23 and restriction 24 to tapping 9 in flow line 2 downstream of valve 4. Valve 4 remains closed until sensor 6 detects a given maximum standpipe level, whereupon diaphragm 13 snaps orifice 16 shut. A vacuum thus builds up in signal line 21 and is communicated via a fixed time delay unit formed by restriction 33 and fluid capacitor 34 to chamber 35 causing a diaphragm 37 to move leftwards and open orifice 40. Vacuum is thus communicated via the latter and tapping 9 to fluid capacitor 41 of a main timing unit incorporating a variable restriction 42 connected to atmosphere via filter 28. The vacuum is also communicated to switch 44 causing diaphragm 47 thereof to move left wards against spring 45 and open orifice 49. Atmospheric pressure is thus communicated via the latter and line 50 to chamber 51 of relay valve 8 causing diaphragm 53 and spool 54 to move downwardly against spring 57. Spool 54 closes aperture 59 before opening aperture 58 to communicate vacuum to operating chamber 11 of valve 4, opening the latter and permitting flow through line 2. As the liquid level in standpipe 5 decreases, the fall in pressure moves diaphragm 13 away from orifice 16 causing atmospheric pressure to be communicated via line 21 to move diaphragm 37 to the right, closing orifice 40 and shutting- off vacuum from timing capacitor 41. In a time period dependent upon the setting of variable restrictor 42, capacitor 41 changes from full vacuum to atmospheric pressure causing diaphragm 47 to move rightwards and cut-off atmospheric pressure from chamber 51 of relay valve 8. Spool 54 of the latter thus moves upwards to vent valve operating chamber 11 to atmosphere, closing valve 4 to complete the cycle. The volume of liquid discharged from standpipe 5 is the same in each cycle.

IPC: A63H23/04
Filed: 1918-07-13
Abstract: 121,722. Waele, R. E. de. Dec. 24, 1917, [Convention date]. Boats, ships, and floating and diving toys.- Relates to submergible toys in which gas generated by the action of water on a chemical causes the toy to rise to the surface, and comprises a water-ballast chamber and valve devices which enable the water to reach the chemical. Fig. 1 shows a submarine toy with a propeller shaft c driven by spring mechanism a and containing a water-ballast chamber e which communicates with the water by a pipe f provided with a plug f<1> which is removed when the boat is to submerge. A valve h seating on a frame g at the top of the chamber e closes the upper part of a cartridge containing calcium carbide. When the valve h is raised by the water entering the chamber e, pins i on the valve contact with a disk n, thereby closing an air-escape valve l in the cover k of a chamber j supported by the frame g. The acetylene generated by the action of the water on the carbide expels the water from the chamber e, and the boat rises to the surface and travels thereon until it is again submerged, when the operations are repeated. The rudder p projects slightly beyond the bottom of the boat and is movable vertically so that, when it strikes against the bottom of the basin in which the toy is used, it rises and engages the propeller blades d and stops their rotation. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an apparatus in which the carbide cartridge q, Fig. 6 (Cancelled), communicates through a conduit r with the outside, and the conduit is normally closed by a device having pivoted arms connected to the operator's hands so that water can be admitted to'the cartridge as desired. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to light machine guns
IPC: F41A19/43
Filed: 1929-04-15
Abstract: 336,600. Nikoloff, C. April 15, 1929. Machine guns.-A short barrel-recoil light machine gun comprises in combination a strikerlever c rotatable within the frame b on pivots e<1>, r<1> under the action of a tension spring g<1>, a breech-plug d, a strikerblock e movable in the breech-plug, and a one-armed stop-lever f pivoted a.t g to the breech-plug. The frame b and the barrel a first recoil slightly against the tension of the spring g<1> when a shot is fired. During this initial stage, the breech-plug and the strikerblock remain interconnected by the stop-lever f, while the striker-block e is resiliently supported by the striker-lever c owing to the spring g<1>. After this initial stage, a hand-lever h strikes against a stop u and rocks the lever c, allowing the striker-block e to move back and release the stop-lever f, which is then swung up by a projection on the striker-block, so that it comes in front of a ledge n on the striker-block, and ribs s<2> on the stop-lever come in line with grooves in the frame b. The frame and the barrel now return forward while the breech-plug and strikerlever continue their recoil, and are subsequently returned forward by the striker-lever c influenced by the spring g<1>. The striker-lever c has faces y and projections w, k in engagement with the striker-block e which is provided with a co-operating rear face z, cam groove x, and slot r<4>. When the breech-plug again reaches the barrel, the stop-lever f falls down again and the strikerblock completes its forward movement; and at the end of this movement, the striker-lever c gives a blow to the back of the striker-block, which blow is transmitted to the firing pin i. The trigger mechanism comprises a lever p and a trigger o controlled by a spring and mounted in a hand-grip m<1>, which is pivoted at the rear on a pin n<3> and is locked in front by a bolt o<3>. In the upper part of the hand grip, a cartridge feeder u<3> is pivoted at v<3> and urged upwards by a spring t<3>, When recoil begins, the cartridgefeeder is wedged down and receives a cartridge from a lateral magazine; and when the breech opens, the cartridge-feeder springs up and brings the cartridge in position for the breech-plug to insert it into the barrel. The magazine has a spring detent, and the cartridge-feeder has a finger grip for hand operation to feed the first cartridge. The spent cartridges are extracted by an extractor on the breech-plug, and ejected through a lateral aperture.

Title: Improvements in the manufacture of sulphamerazine
IPC: C07D239/69
Filed: 1954-04-26
Abstract: Sulphamerazine is prepared by adding b ,b -dichlorobutanone-2 to a suspension of sulphaguanidine in alcoholic alkali metal alcoholate and heating at 40-70 DEG  C., with subsequent acidification of an aqueous solution of the alkali metal salt of sulphamerazine so formed.  The process may be combined with the preparation of b ,b -dichlorobutanone-2 by admixing acetyl chloride, vinyl chloride and a Friedel-Crafts catalyst in an inert organic carrier liquid whereby a complex of the ketone and catalyst is precipitated, separating this complex, and decomposing it with cold water, preferably iced and acidified, whereby the b ,b -dichlorobutanone-2 separates as a lower oily layer.  In a preferred method of carrying out this reaction the acetyl chloride and the preferred catalyst, aluminium chloride, are admixed in the preferred carrier liquid, carbon tetrachloride, at 0-25 DEG  C. and gaseous vinyl chloride is passed in at a rate of 0.1 to 1.0 mols. per hour and at a temperature not exceeding 18 DEG  C. Other acidic metal halides such as stannic chloride, stannous chloride and ferric chloride may be used as catalysts.  Other carrier liquids mentioned are low-boiling petroleum ethers and carbon bisulphide.  In the second stage of the process the b ,b -dichlorobutanone-2 is preferably added at such a rate that the temperature of the mixture does not rise above 50 DEG  C.  The preferred alkali metal alcoholate is sodium methylate and the preferred amount of sodium is about 3-4 mols. per mol. of b ,b -dichlorobutanone-2.  Examples are given.ALSO:b , b -dichlorobutanone-2 is dried by azeotropic distillation under reduced pressure in the presence of carbon tetrachloride as a water-entraining agent.
