Abstract: <PICT:0389095/III/1> <PICT:0389095/III/2> In an emulsifying-machine in which the periphery of a disc 1 revolves in close proximity to a ring 10, the liquid is forced centrifugally into each side of the gap between the ring and disc and passes outwardly through a central groove 13 in the ring into an annular or volute discharge space having a controlled outlet. As shown in Fig. 1, the disc 1 rotates within a casing 4, 5 and is provided with a cylindrical grinding surface on the periphery. The central groove 13 may be formed in an integral ring 10 or the latter may be divided into two parts which are spaced by distance-pieces.  Rings of different diameter may be used to vary the clearance of the grinding space.  The liquid &c. enters an orifice 6 and the disc 1 is perforated to equalize the liquid pressure on the sides thereof and may be formed as a centrifugal pump impeller.  The discharge chamber 11 around the ring 10 may be of uniform cross section or may be of spiral form and the outlet is controlled by a valve.  Instead of the disc being perforated to equalize the pressure, the casing may be provided with a channel which communicates with both sides of the disc.  In Fig. 7, the periphery of the disc 1 has inclined faces 8, the gap being adjusted by screwing inwardly or outwardly a cap 5.  The inclination of the faces 8 may be substantially parallel with the shaft axis or at right-angles thereto.  Specification 214,308, [Class 59, Grinding, crushing, &c.], is referred to.

Abstract: 1339786 Gas cushion vehicles M BARTHALON 19 April 1971 [1 April 1970 22 Sept 1970] 25346/71 Heading B7K [Also in Division F2] In a pneumatic system in which an object is supported or guided adjacent a wall by a gas layer at a pressure different from ambient pressure, provision is made to ensure the travelling object always maintains a substantially constant distance from the wall. In Fig. 1, in which a vehicle 3 is suspended beneath a track 2 by a negative pressure gas layer in a supporting chamber 6 bounded by a rectangular skirt 5, four balancing chambers 15 are provided each comprising a movable face 14, an upwardly biased spring 17 and a nozzle 22, air being drawn through the latter by a fan 8. If the distance d increases, the value of the negative pressure created by the fan 8 in the chamber 15, decreases and the spring 17 urges the face 14 upwardly to restore the gap. If distance d should decrease, increased negative pressure thus created in the chamber 15 results in downward movement of the face 14. In a modification, Fig. 4 (not shown), the face 14 is mounted on a flexible membrane (31) the movement of which is damped by dashpots (71), and the nozzles 22 are located outside the skirt boundary. In Fig. 5, a vehicle 50 is supported on a positive pressure cushion in a chamber 54, air being also supplied to a balancing chamber 56 and through ports 68 in an axially slidable nozzle 64 mounted to a membrane 57 which is urged downwardly by a spring 63. In Fig. 9, the balancing chamber 17a has its movable face defined by a double walled envelope 102 provided with nozzles 122 and is inflated to a pressure greater than both atmospheric and that in the chamber 17a. In modifications, the envelope is formed by two separate oval shaped tubes secured at their respective tops to a central longitudinal beam (205), or by a bi-convex tube (251) having thick lateral convex portions to produce the restoring force on the skirt (255). In a final embodiment, Figs. 7, 8 (not shown), the balancing chamber is formed by a bellows (86) and the restoring force is provided by a flat spring (85) and additionally by a further bellows (70) mounted in the supporting chamber.

Title: Concentrated formaldehyde solutions
IPC: C07C45/78
Filed: 1952-10-20
Abstract: Liquid compositions containing formaldehyde are made by passing formaldehyde vapour of low water content into a liquid aliphatic hydroxy compound so as to absorb the formaldehyde therein while cooling the composition being formed to a temperature at least about 20 DEG  C. below its boiling point but not below 50 DEG  C. Advantageously the temperature is about 20-40 DEG  C. below the boiling point of the composition.  The vaporous formaldehyde contains less than 20 per cent by weight of water.  The formaldehyde vapours may be anhydrous as obtained by heating alkali precipitated a -polyoxymethylene or may be obtained by vaporizing an aqueous solution of formaldehyde and condensing out part of the water. Hydroxy compounds specified include methanol, isobutanol, ethylene glycol, glycerol and erythritol. Advantageously a circulating system is used in which a solution of the desired concentration is obtained and circulated between a zone where fresh reagents enter the system and a cooling zone, the product being withdrawn at a point remote from where fresh reagents are supplied at such a rate as to keep constant the volume of composition in circulation.  With products containing above 70 per cent by weight of formaldehyde it is best to limit the residence time to not more than 120, preferably 60, minutes. Examples show the production of solutions of formaldehyde in n-propanol, methanol and 1,2-propylene glycol.
