Title: Improvements in the thermal compression of gaseous sulphur dioxide
IPC: C01B17/50
Filed: 1931-10-20
Abstract: <PICT:0396027/III/1> Sulphur dioxide is absorbed by means of aliphatic or cyclic amines, hydroxylamines or hydrazines or heterocyclic nitrogen compounds and is expelled from these solvents against pressure by heating.  The amines &c. referred to are pyridine and quinoline. In order to prevent the crystallization of addition compounds of sulphur dioxide from the absorption media, aliphatic or cyclic alcohols or ketones may be added thereto.  Examples of such additions are glycerol, glycol, benzyl alcohol, ethyl methyl ketone, methanol and ethyl alcohol.  Water may also be added.  The process may be applied to an absorption refrigerating-machine. Sulphur dioxide from an evaporator 46 enters an absorber 34 at low pressure where it is absorbed by an alcohol-pyridine mixture.  The solution is pumped from the absorber by a pump 36 through a heat exchanger 37 and heating element 38 into an evaporator 39 where the sulphur dioxide is driven off at a temperature of about 80 DEG  C. The solvent returns to the absorber 34.  The sulphur dioxide leaves the evaporator at a pressure of 4 atmospheres and passes through a rectifier 51 to a water-cooled condenser 3 where it is liquefied.  The liquid sulphur dioxide passes to a storage vessel 45 and thence to the evaporators 46.  The process is also applicable to the production of liquid sulphur dioxide from stack gases.

Title: Improvements in method and apparatus for conditioning a tampon and tampon applicator assembly
IPC: A61F13/20
Filed: 1949-11-21
Abstract: 660,978. Catamenial tampons. OAKLEY, J. L. D. (International Cellucotton Products Co.). Nov. 21, 1949, No. 29730/49. Class 81 (ii). An apparatus for adjusting and finishing the parts of a tampon comprises means for holding the applicator body while pressing the tampon in to a predetermined position, pressing the ejector tube into contact with the tampon and softening the end of the tampon. The tampons are received from a supply chute assembled but not adjusted and are intermittently stepped forward through a series of rest positions by a link belt 19 having upwardly projecting pegs 20 for engaging the tampons. As each one advances, a stepped guide 9e drives the applicator tube 2 towards a side guide 47. In the position A a plunger 49, carried on a cross-head 50, presses the ejector 4 into the applicator tube 2 until it engages the inner end of the tampon. In the following position B a narrow plunger 58 engages the end 3 of the tampon and thrusts it inwards to the desired extent, the applicator 2 being held by the step 9c. At C a second plunger 65 on cross-head 50 pushes the entire assembly forward, the ejector being in engagement with the tampon, whereupon the head is shaped by being pressed into a countersunk recess 67, from which a plunger 66 disengages it prior to its passing through two idle positions to position D, where the projecting end 3 is fluffed and softened by a rotating and reciprocating head 74, having radial teeth on its circular end face except for an eccentric recess, see Fig. 10 (not shown) so that the end of the tampon is softened to an extent increasing from the centre outwards. Finally the end of the tampon is flattened by a plunger 100 without compacting it and an interlocking tab 5 is punched through the applicator and ejector tubes by a fluid-actuated triangular punch, the finished tampon then being passed to a packing machine.

Abstract: 1,208,335. Container closures. M. MELOCCHI. 21 June, 1968; No. 29870/68. Heading B8T. A reclosable dispensing closure for a container has a spout which protrudes only when the closure is open. A container 1 has an axially offset neck 2 on which is threadably mounted a spout 6, the top of the neck being in sealing engagement with the spout when the spout is in its lowest position. The end of the spout 6 passes through a hole in a rotatable outer casing 7, rotation of which causes the spout to move upwardly, thus opening the closure and causing the spout to protrude. Alternatively the opening may be effected by aligning an aperture (14) in the neck 2 with the spout 6, Fig. 5 (not shown), the spout being mounted for rotational but not upward movement. In another embodiment, Fig. 6, the spout points upwardly, projecting in an axially offset position on a threaded cap 5 mounted on the neck 2, upward movement of the cap 5 causing the closure to be opened on rotation of the outer casing 7. Again, a hollow member (22) may be fixed to the neck 2 and extend up into the spout, Figs. 9-11 (not shown). The spout may be disposed on the axis of the container and have a diaphragm (19) partly closing its outer end. Rotation of outer casing 7 causes the cap 5 to rotate by means of interengaging ribs (16, 17, 18) thus raising the diaphragm from blocking the end of the member (22) and opening the closure through axial movement.
