Title: An emptying device for containers for bulk material
IPC: B65D88/62
Filed: 1964-08-04
Abstract: 1,028,538. Hoppers. FRANZ CLOTH RHEINISCHE GUMMIWARENFABRIK A.G. Aug. 4, 1964 [Dec. 2, 1963], No. 30948/64. Heading B8S. A container for bulk material has disposed in a corner thereof a device for preventing the conglomeration of material in the container or for loosening conglomerated material, the device comprising a rigid base-plate 3 forming an angle adapted to that of the adjacent container walls and a diaphragm 1 of elastic material adapted to be inflated to the chain-dotted line position. The diaphragm 1 is clamped by screws 2 between bars 4 welded to the baseplate 3 and bars 5, such that the diaphragm covers the base-plate and provides a rim 6 which seals the gap between the container walls and the base-plate 3 when the device is fastened to the walls by screws 7. A compressed air inlet 9 and an outlet 10 are provided. The baseplate 3 is stiffened by ribs 11. A draw-valve 12 is connected to the diaphragm 1 by cords 13 so that if the diaphragm is inflated beyond the chain-dotted line position the valve 12 is opened to reduce the air pressure. The diaphragm is lightly prestressed along a zone thereof adjacent the bend zone of the base-plate and its wall thickness in this zone is increased. The diaphragm may be reinforced with fabric inserts having threads which extend obliquely of the prestressed bending zone.

Title: Improvements in or relating to the purification of gases containing sulphuretted hydrogen and ammonia
IPC: C10K1/10
Filed: 1929-10-12
Abstract: 336,425. B÷nnemann, F. Oct;. 12, 1929. Drawings to Specification. Condensing, scrubbing, and washing processes. -Gases which contain ammonia and sulphuretted hydrogen, the latter being present in greater amount than is represented by the ratio 2NH3: 1H2S are divided into two portions, one containing as much sulphuretted hydrogen as can be combined with the available ammonia which is concentrated therein to eliminate the sulphuretted hydrogen. The other portion after removal of the ammonia may be used for firing gas producers or it may be treated in a separate plant for removal of the sulphuretted hydrogen and then reunited with the other purified portion. The crude gases may be first cooled to separate ammonia and tar and the ammonia driven off by treatment with lime and added to the first portion of gas. Any ammonia remaining in the other portion is also driven off and added to the first portion. The division of the gas stream may be adjusted according to a mean value of the ammonia and sulphuretted hydrogen and variations in the ratio compensated for by maintaining the scrubber slightly ammoniacal.

Title: A new or improved process for the continuous coating of sand or like granular material with resin
Inventor: LAWRENCE ANTHONY WALTER
IPC: B22C5/04
Filed: 1962-08-16
Abstract: Resin-coated granular material, for example sand, is prepared by feeding the preheated granular material in a continuous stream together with a synthetic water soluble condensation resin in a continuous stream to one end of a combined mixer and conveyer unit, mixing and simultaneously conveying the granular material and resin for a time such as to take the resin to its bonding point (defined in the Specification), adding to the mixture a resin curing agent, which may be hexamethylenetetramine, in a continuous stream, and mixing and conveying the resultant mixture for a time such that a continuous stream of storage-stable free-flowing resin-coated granular material is discharged from the unit.  Before addition of the curing agent, an acid, such as formic or oxalic acid, may be added to the mixture to neutralize free alkali present in the resin.  The mixer-conveyer unit may conveniently comprise three successive troughs containing worm conveyers, granular material and resin being fed into the first trough, acid and curing agent being fed into the second trough, and the third trough serving as a final mixing, aerating, drying and cooling stage from which is discharged the resin-coated material.
