Title: Improvements in or relating to the recovery of sulphur dioxide from gas mixtures
IPC: C01B17/60
Filed: 1932-05-06
Abstract: Gases containing sulphur dioxide in low concentration are treated with an aqueous solution containing one or more salts of stable non-volatile acids having dissociation constants lying between 1 x 10<-2> and I x 10<-5> and the sulphur dioxide is subsequently expelled by heating and/or reduction of pressure with a regeneration of the solvent.  Suitable acids are lactic, glycollic, citric or ortho-phosphoric acids.  The basic radical may be an alkali or alkaline earth metal or ammonium or any other base which does not lead to undesirable precipitation.  When the gases treated contain free oxygen an undesirable accumulation of sulphuric acid in the solvent should be avoided e.g. by purging a portion of the circulating liquor or by treating the circulating liquor or a portion thereof for the removal of sulphuric acid. Examples relate to the treatment of sulphur dioxide containing gases with aqueous solutions of sodium citrate, mono-ammonium phosphate or a mixture of mono-sodium phosphate and sodium citrate.  The use of aqueous solutions containing sodium citrate and mono-ammonium phosphate or containing mono-sodium and mono-ammonium phosphates with mono-magnesium phosphate in suspension is also referred to.

Abstract: 639,263. Drying cloth. DUNGLER, J. May 15, 1947, Nos. 13166 and 13167. Convention dates, May 22, 1946 and Feb. 21, 1947. [Class 34(i)] A machine for drying cloth in long lengths by blowing air on to it has two sets of blowing nozzles disposed at opposite sides of the rectilinear path of the cloth, directly opposite one another while leaving a space between them for the passage of the cloth which is carried therethrough between two portions of a conveyer. As shown, drying elements 35 having blowing boxes 13 and nozzles 14, which may be telescopic, are located either side of the cloth a and extend over its width. The cloth is made to fall freely through the space between the nozzles 14 by means of an endless band conveyer comprising upper and lower foraminous bands 25 which engage the cloth between them as it enters the casing at 30 and the moist air escapes through the spaces between the nozzles. In a modification the foraminous bands are replaced by rollers located above and below the cloth in the space between the blowing nozzles, the said rollers rotating in synchronism at a peripheral: speed lower than the rate of feed of the cloth. In a second version of this modification the upper rollers rest against the: lower. The rollers may be perforated or have grooves or projections. Specification' 578.735 is referred to. The Specification as open to inspection under Sect. 91 also comprises (Cancelled Figs. 1 and 2 not shown) a circular drying machine having a rotary drum provided with blowing boxes and peripheral telescopic nozzles and means for heating air which is supplied through the hollow shaft of the drum. A set of mutually spaced rollers surrounds the nozzles leaving a narrow circular space through which passes the cloth and an endless conveyor band, the cloth being pressed against the band by the air blown from the nozzles. Also described (Cancelled Figs. 9 and 10 not shown) is a rectilinear type of machine in which the conveyer has only lower rollers which may be connected together in pairs, the distance between the lower nozzles and the cloth being greater than the distance between the upper nozzles and the cloth so that the air blown by the upper nozzles presses the cloth against the rollers. It is stated that in the machine having two foraminous conveyer bands the lower conveyer may comprise an endless felt band stretched between the inlet and outlet rollers, the lower drying element 35 being eliminated. This subjectmatter does not appear in the Specification as accepted.

Title: Spinning or twisting machine
IPC: D01H13/04
Filed: 1966-03-29
Abstract: 1,119,592. Spinning apparatus. J. J. KEYSER. 29 March, 1966 [7 April, 1965], No. 13693/66. Headings DID and D1J. In spinning-apparatus material from drafting or delivering-mechanism is laid on a sleeve by a guide rotating around it, the sleeve being rotatably mounted on a hollow shaft which extends over the length of the sleeve and is secured to the machine frame, the material passing axially through the shaft, being deflected in the opposite direction at the outlet end of the latter, then passing to the guide. By this arrangement, two twists are inserted for each revolution of the sleeve; the package may be rewound without having to doff it and the use of a package-sleeve is unnecessary. The guide may be a ring and traveller, a cap, or a wing-flyer. In Fig. 1, a stationary hollow shaft is suspended from a hollow rail 4. A sleeve 15 is rotatably and concentrically mounted in upper and lower bearings on the shaft, and is driven by a tangential belt 16 pressed into engagement with the sleeve by a roller 17, the belt and roller being arranged in the rail. When an additional bobbin sleeve is used, it is supported on sleeve 15 by a ball-catch in a plug 14 between the bottom of shaft 7 and sleeve 15. A ring 20 with a traveller surrounds the sleeves and is reciprocated along a fixed guide rod 19 to build the package, by a finger 23 engaging an endless chain trained over two pulleys, one of which is driven. The incoming material takes an inclined path 27 to the top of the tube 7. It passes down the tube and is deflected upwardly to reach the traveller, at the bottom of the tube. The rail is in two parts 4, 3 hinged together at 6: the part 3 is fixed to the frame and contains the belt 16 and roller 17 and the part 3 carries the tube 7, sleeve 15 and rod 19 together with the ring 20. Thus, when the package is built, the part 4 of the rail can be swung outwardly to interrupt the drive and allow the package to be doffed or rewound directly by mechanism below it. In another form, Fig. 3, the shaft is made in two telescoping sections, the inner one 7a carrying the two legs of an inverted flyer 30 which is rotated around the package by a worm-gear 36. The sleeve in this case is supported by a spring-clip 12, and is driven by a worm gear 29 in the two-part hollow rail 3, 4. The incoming material passes down the shaft 7 and through a channel within one leg of the flyer to a foot 32. The gear driving the flyer is housed in a hollow rail which can be moved downwardly, taking the flyer with it, in a vertical track for doffing. In another form, the flyer is replaced by an inverted cup, and the package can be supported and driven from below, the delivery or drafting mechanism being also arranged below the package.

Title: Improvements relating to dishware lining machines
IPC: B28B11/00
Filed: 1950-06-01
Abstract: A lining unit for dishware has a chuck mounted on a rotatable and axially moveable spindle and means co-operating with the spindle to define a volume variable according to the axial position of the spindle in the unit, the said variable volume means being connected with the chuck and the arrangement being such that when ware is placed on the chuck while the variable volume means defines a minimum volume axial movement of the spindle causes a vacuum to be created to hold the ware on the chuck.  Referring to the drawings, when spindle 20 is moved, e.g. by means of a treadle, against spring 36 driving gear 35 engages pinion 45 of constant running motor 40 thus causing rotation of the spindle.  Further, movement of piston 38 creates a vacuum between it and head 33 which vacuum is communicated <PICT:0682551/III/1> <PICT:0682551/III/2> via port 28 and space 24 to chuck part 27 and hence holds the dishware on chuck 25.  Centring device comprises gear 50 engaging three pinions 53 carrying centring pins 55 which can be moved from their position of maximum opening shown in Fig. 4 towards the centre of chuck 25 by swinging handle 51 counterclockwise.  The lining device is supported on staff 60 and cross staff 62 each provided with scales so as to set the rotative positions of the staffs according to predetermined settings, and comprises a colour vial 72 mounted on cotter 71 on which is also mounted a fork carrying a small lining wheel 75.  Modifications disclose the replacement of cylinder 30 and piston 38 by a bellows to obviate wear and tear by dust and grit, the location of port 28 so that when spindle is retracted it is just outside head 33 and so opening out to atmosphere, the interpositioning of a cushioning spring between cylindrical head 31 and the vacuum chuck, and the movement of cylinder 30 to end of spindle 20 with a spring interposed between chuck and the cylinder so that a vacuum can be produced without using a port 28, the provision of an edge-following device to space the lining wheel accurately from the edge, and the addition of a second wheel below the former lining wheel which now becomes a transfer wheel, the second wheel becoming the lining wheel.  A number of such lining units 10 may be employed in a multi-spindle machine as shown in Fig. 17.

Abstract: 1509731 Bearings F HECK 4 April 1975 [6 April 1974] 13959/75 Heading F2A [Also in Division B3] A method of making a lined bearing comprises applying a layer of metallic bonding material to the radially inner surface of a bearing ring and casting on a layer of lining material in the presence of steam and a flux. The bonding material may be tin or an alloy thereof, the lining material may be white metal and the flux may be one or more of zinc chloride, stannous chloride, stannic chloride, lead chloride, antimony trichloride, antimony oxychlorides and ammonium chloride. A steel ring 1 is first cleaned and then a slurry containing tin powder and flux optionally together with some nickel powder and small iron articles such as nuts or rivets, is applied thereto. The ring is then placed in an oven (5) and slowly rotated whilst being heated to 300‹ C. to melt the tin. After removal from the oven the nuts or rivets are removed from the ring and the latter clamped between a pair of cones 9 and 10 in a centrifugal casting machine 8. An aqueous solution of flux is then introduced into the casting chamber 11 through a pipe 26 resulting in the sudden formation of steam and a fine distribution of flux. The pipe 26 is then withdrawn and molten white metal introduced through a pipe 21. During the centrifugal casting process the ring is cooled by water from nozzles 28. Gaseous chlorine may be introduced into the casting chamber 11 prior to pouring in the molten lining material and cones 9 and 10 are preferably provided with a plasma layer of alumina or titanium. In a modification, a flux layer is applied to the surface of the ring before the tin powder.
