Filed: 1941-05-19
Abstract: 548,490. Stripping dyed textiles. LICHTENSTEIN, L. A. May 19, 1941, Nos. 6398 and 15389. [Class 15 (ii)] Dyed textile material is stripped by treatment with an aqueous solution containing a reducing agent and a water-soluble derivative of anthraquinone or of a substituted anthraquinone which on reduction yields the corresponding derivative of anthrahydroquinone. Specified reducing agents are glucose, molasses, sodium sulphide, formaldehyde, sulphite waste liquor, formaldehyde sulphoxylates and hydrosulphites. In examples, (1) a cotton fabric dyed with 4- nitroaniline # 2-naphthol, formed on the fibre, is stripped by a treatment for 15 minutes with an aqueous solution at 80‹C. containing glucose or sodium sulphide, sodium carbonate and sodium anthraquinone-2-sulphonate; (2) a cotton fabric, dyed with Artificial silk black GN, is stripped by a treatment for 15 minutes with a boiling aqueous solution containing Formosul and sodium anthraquinone-2-sulphonate ; (3) wool yarn, dyed with Croceine scarlet 3B, is stripped by a treatment for 15 minutes with an aqueous solution at 80‹C. containing glucose, sodium phenate or ammonia, and sodium anthraquinone-2-sulphonate ; an addition to the solution of a sodium alkylnaphthalenesulphonate is advantageous in preventing felting. Specifications 434,810, 436,076 and 437,884 are referred to. The first Provisional Specification refers also to the use of anthraquinone carboxylates as water-soluble anthraquinone derivatives and gives an example of the stripping of material dyed with the dyestuff, 5-chloro-2-aminotoluene # the 2<SP>1</SP>-toluidide of 2:3-hydroxynaphthoic acid, by a treatment for 10 minutes with an aqueous solution at 80‹C. containing glucose, soda and sodium anthraquinone-2-sulphonate.

Title: Improvements in or relating to safety filling devices
IPC: B65D83/14
Filed: 1968-02-09
Abstract: 1,218,434. Filling and emptying bottles; venting containers. FRASER SWEATMAN Inc. 9 Feb., 1968 [17 Feb., 1967], No. 6665/68. Headings B8T and B8X. A safety filling device particularly for a vaporizer for anaesthesia apparatus has interengaging means, preventing the interconnection of wrongly matched containers, and valves controlling the flow of liquid. The top of the vaporizer (2), Fig. 1 (not shown), has an opening 12 and a collar 14 inside which fits a tube 16 with a gasket seal 18 between the two. Liquid flow through a reduced inlet portion 20 is controlled by a ball check valve 22 urged upwardly against its seating by a spring 24. Liquid flows through openings 28 and 30 when the valve is open. A cap (40), Fig. 3 (not shown), fits over the tube 16 when the vaporizer is not in use. Pins 32 and 34 pushed onto the top of tube 16 engage loosely with openings 72 and 74 in the cap of a second container 50. The orientation of these pins and openings is such that only the correct liquid container can be connected to a particular vaporizer. A ring-shaped check valve 76 closes openings 72 and 74 except when the vaporizer is connected and pins 32 and 34 open the valve to allow air to pass through a passage 80 connected through tube 84 to a cup-shaped member (88), Fig. 5 (not shown), with a disc (90) threaded to the inside thereof, the disc having openings (98) which can be closed by a washer (100) slidably mounted on a tube 94. In a conduit 62 on the second container is a valve stem 114 coacting with ball valve 22 and urged downwardly by a spring 110. When the container and vaporizer are brought together, tube 69 slides into conduit 31 and valve stem 114 opens first the ball check valve, then the seal provided by a cup-shaped member 112 urged against a face in sleeve 64 by a spring 110. Liquid can then flow freely into the vaporizer. A similar arrangement is used to drain unused liquid from the vaporizer, to prevent draining into the wrong container, Fig. 8 (not shown). The second container has a cap (120), Fig. 2 (not shown), to close it when not in use.

Title: Improvements in radial flow elastic fluid turbines
IPC: F01D1/28
Filed: 1944-04-11
Abstract: 572,657. Elastic-fluid turbines. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. April 11, 1944, No. 6669. Convention date, April 27, 1943. [Class 110 (iii)] In a radial flow turbine, admission of overload steam and extraction of steam for outside consumption purposes are provided for at the same intermediate staged, and may take place simultaneously. Steam is supplied to chambers 6, 7 through conduits 10, 11, and thence through passages 8, 9 to the blading. Chamber 12 and passage 19 are used for the admission of overload steam to the intermediate stage 25 ; and passage 20, chamber 13 and conduit 24 are used for extraction of steam from the blading. Extraction steam thus performs useful work in the inner stage before being bled, and it is stated that the temperature of the extraction steam remains practically constant" at different conditions of overload. The flow of steam through the blading prevents overload steam passing to 20. In modifications, the two sets of blading may be relatively displaced axially and may have attached deflector strips extending from one or both sets of blades.

Title: Improvements relating to Electric Time Switches.
Inventor: ABRAHAMSON MARTIN ARNOLD
IPC: H01H43/30
Filed: 1918-04-22
Abstract: 125,514. Abrahamson, M. A., Tvermoes, H. E., and Christiansen, L. April 22, 1918. Thermal switches. - In a thermally-controlled time switch, the circuit-closing is effected by an electromagnet, the expansion of the heated member serving to short-circuit the electro-magnet so that the current is cut off from the heating unit. Subsequent cooling of the heated member initiates the breaking of the main circuit. As shown, the device is applied to controlling the burning period of a number of lamps 16 for lighting a stairway, each lamp being associated with a push-button 17. A filament lamp 3 forms the heating unit, and a double strip 4 the heated element. The strip 4 carries a contact 5 co-operating with an adjustable contact 31, and a spring 7 having a contact 6 cooperating with an adjustable contact 30. The armature 9 of an electro-magnet 8 carries contacts 10, 11 co-operating with fixed contacts 12, 13. When any button 17 is pressed, current passes from the lead 14 through all the lamps 16 and by way of lead 21 through the magnet 8 to the return lead 15. The armature 9 is attracted, closing contacts 10, 12, 11, 13. Current flows through lead 27, contacts 13, 11, and winding 8 so that the magnet 8 and lamps 16 remain energized when the button 17 is released. At the same time, current passes through the lead 25 and lamp 3. When the strip 4 is sufficiently heated, contacts 6, 30 are first closed, and then contacts 5, 31. The magnet is thus short-circuited through contacts 5, 31 and strip 4, contacts are broken at 12, 13, and lamp 3 is de-energized. Current continues to flow through lamps 16, lead 27, and contacts 6, 30 until cooling of the strip 4 breaks contacts at 5. 6. A switch 24 serves to cut out the time device and light the lamp 16. In a modification intended to give finer adjustment of the time period, quicker, make and break, and for use with stronger current, the heated member comprises a tube surrounding the lamp 3. The expansion and contraction of the heated member operate the shorter arm of a lever, the longer arm of which carries the short-circuiting contact. The main circuit is broken by contacts on the electro-magnet armature, which is retained in the attracted position by a hook catch formed on the lever, until released by the contraction of the heated member. The lamp 3 is in series with the push-bottons 17 and electro-magnet, and a safety contact may be used, operating to break the circuit on sticking or non- release of the button 17.

The sides of the seat section are cranked inwardly at 201 and the front leg section 23 is pivoted to the front bar 21 and is limited in the unfolded condition by inturned ends of the cranked parts 201. The outward motion of rear leg section 24 is limited by an inturned projection 204 on the sides of the seat section and an out-turned projection 203 limits the outward motion of the back section. The rear leg and back sections are pivoted on the rear bar 22 of the seat section. Bars 21, 22, 26 have threaded ends engaged by nuts 281, 282, 283. The material 27 may be hooked by eyelets to the bars 21, 26 and may have press-studs along its edges so that it can be detached and joined up as a bag. In a modification, the seat and back sections are of D-shape, the straight parts of which are at the junction of the seat and back. According to the first Provisional Specification, separate sheets of material may be used for the seat and back, the rear of the sheet for the seat being connected to the rear bar by springs. The front bar of the seat section may also be cranked to co-operate with the cranked part of the upper bar of the back to form a handle, a resilient clip being provided to hold the parts together when folded.

Abstract: 154,944. Armstrong, Whitworth, & Co., Sir W. G., Lee, H. W., and Webster, T. March 19, 1919. Sights.-Relates to sights in which means are provided for deflecting the sight line to compensate for inclination of the trunnion axis, and consists in means whereby, when the trunnion axis is inclined, the sight is deflected through an angle whose sine is equal to the product of the tangent of the angle which the trunnion axis makes with the horizontal into the tangent of the angle of elevation, without tilting the sight about an axis parallel to the axis of the piece. In the form shown in Fig. 1, the sight carrier A<1> is pivoted in a vertical bearing A' carried by an arc I displaceable relatively to the elevating-arc J of the gun by operating a hand-wheel K<1>. Attached to the sight-carrier A<1> is an horizontal arm B having a roller B<1>, Figs. 3 and 4, adapted to work in a slot in a part C which may be rotated about an axis c by worm gearing actuated from a milled head F<2> in order to bring the slot vertical as indicated by a level C<2>. The part C is carried in a frame D slidable vertically in a casing E mounted on the arc I, said frame being adapted as the gun is elevated for range to be raised by an arm G connected by a parallel-motion linkage H, L', L with the elevating-arc J. The part C is thus (1) rotated through an angle equal to the inclination of the trunnion axis to the horizontal and (2) raised through a distance proportional to the elevation of the gun. The arm B, and therefore the sight, is deflected through an angle whose sine is equal to the product of the tangents of these quantities. A modification is described in which the device is adapted to a gun having an independent line of sight.
