Title: Apparatus for removing volatile solvents from fabrics and the like material after dry-cleaning
IPC: D06F43/02
Filed: 1944-02-24
Abstract: 579,898. Removing solvent from dry-cleaned materials. WILLIAMS, W. P. (American Laundry Machinery Co.). Feb. 24, 1944, No. 3484. [Class 91] An apparatus for removing residual volatile inflammable solvent from wearing apparel, fabrics and other materials which have been dry - cleaned comprises a container in which the materials are agitated while being subjected to a current of hot air at a temperature materially above the flashpoint of the solvent, with means operated by the airstream whereby the supply of hot air is cut off whenever the rate of airflow falls below a value sufficient to ensure such dilution of the vaporised solvent as to prevent any possibility of combustion of the air-solvent vapour mixture. In Figs. 2 and 4, the container is a rotatable foraminous drum 12 enclosed by a casing 11. Fan 34 sucks atmospheric air through the drum, the air entering via the chamber 47, containing banks of steam coils 43 and 44, which is mounted on the top of the casing. In pipe 37 on the delivery side of the fan is a weighted hinged vane 38 the shaft of which operates a switch which cuts off the steam supply to the steam coils when the rate of air flow falls below the critical value. An arrangement of dampers also brought into play by the switch on the shaft of vane 38 is described whereby, simultaneously with the cutting off of the steam supply, the steam coils are also by-passed so that cold air is immediately sucked through the drum. Safety devices are also described whereby the door in casing 11, through which the drum 12 is filled with the materials to be dried, cannot be opened when the temperature of the current of air exceeds the flashpoint of the solvent or when the current supply to the fan motor fails and whereby the apparatus is flooded with steam when the current supply to the fan motor fails. A device is also described for automatically bypassing the banks of steam coils 43, 44 at the end of a pre-determined drying period so that the dried materials are cooled in a current of cold air. The drying of materials which have been drycleaned with the hydrocarbon solvent for grease known as 140-F solvent is referred to.

Abstract: 678,276. Pneumatic discharge of bins. HURON PORTLAND CEMENT CO. Feb. 12, 1949. [Sept. 25, 1948] No. 3889/49. Class 78 (i). A bin (Figs. 1 and 8) comprises a pivotable aerator 26 disposed on the floor of the bin for supplying a gaseous medium to material in the bin to aerate and discharge the material, said aerator comprising an elongated channel with non-porous side and end walls and a porous wall 30 of tight woven fabric material closing the top and serving as a support for material to be conveyed to the discharge outlet and along which the material flows when aerated, which porous wall is inclined downwardly to the discharge end thereof at an angle to the horizontal at least equal to the angle of repose determined in the aerated state of the specific material to be conveyed from the bin, and has such a resistance to the flow of the gaseous medium that the gaseous medium flowing therethrough is substantially uniform in volume and pressure throughout the length and breadth thereof, the said channel having an inlet thereon through which air under pressure can be supplied to the channel through the porous wall to aerate material thereon whereby the aerated material will flow along the porous wall and out through the discharge outlet. Fig. 8. Aerator has air box '26' provided with canvas belting top 30 secured by the flanges between the 'box' 26 and angle iron guides 31. The latter may be omitted. Air at low pressure passes up through the canvas and aerates material resting thereon and when the aerator is inclined the material flows down the canvas. Figs. 1, 2, 7. A trailer bin 1 containing cement is formed with sloping bottom sides 7, 10, 9, 8 which constitute twin hoppers having base channels formed of plates 20, 23, 21 each fitted with an aerator 26 of the type of Fig. 8 at the bottom. Each aerator is removable and is slidden through discharge opening 12 in wall 4 over a small retaining ledge 35 into the hopper base channel between (e.g.) walls 9 and 8. It is secured against rattle therein by rubber tubing 47 and is fed with air through a nipple formed in the bottom of the aerator and passing through a similar coupling formed in the base channel, the coupling being connected by flexible piping to pump 42 driven by engine 43, both of which are positioned within the space between walls 9 and 10. The base channels slope towards the discharge so that when air is passed from the box 26 up through canvas wall 30 the aerated cement slides downwards and is discharged through openings 11 and 12, and discharge pipe 13. Material enters through cover in bin 1 (not shown). The aerator may alternatively be formed with flexible flanges so that it may be slid into position from above and the flanges will hold it in position and seal off the gas. Fig. 10. Material is discharged from hopper 55 by means of four inclined aerators 57 arranged radially, the air being introduced through pipe 60 and the material being discharged at 56. Specification 677,890 is referred to.

Patent GB-493997-A (GB)
Title: Process for the production of fadeless tanning agents
IPC: C14C3/20
Filed: 1938-02-09
Abstract: Tanning-agents are obtained by condensing mixtures of phenolsulphonic acids (or their homologues) and dioxydiphenyl sulphones (or their homologues) with urea and formaldehyde, or with urea-formaldehyde condensation products, with the addition of a diluent to the mixture in a proportion sufficient to yield a mixture which can be thoroughly stirred at the reaction temperature; water or a hydrophile organic solvent, e.g. glycerol or glycol, is a suitable diluent.  The molecular ratio of urea to formaldehyde may be 1 : 2 when phenolsulphonic acids and dioxydiphenyl sulphones of relatively high reactivity are taken; in other cases, the formation of water-insoluble products can be avoided (a) by increasing the proportion of formaldehyde relative to the proportion of urea, e.g. by using 4 mols. of formaldehyde per mol. of urea, and/or (b) by effecting the reaction in the presence of a naphthalene sulphonic acid or a formaldehyde condensation product thereof, or in the presence of a dispersing agent such as sulphite-cellulose lye.  When pre-formed urea-formaldehyde condensation products are taken, additional amounts of urea and formaldehyde may be added, if desired. In the examples, (1) crude cresol is sulphonated, and the product is dehydrated by vacuum distillation and then treated at 125-130 DEG  C. with crude cresol, whereby a part of the sulphonated cresol is converted into dioxydicresyl sulphones; the product is diluted with water and treated, at a temperature not above 45 DEG  C., with a product obtained by condensing urea with formaldehyde in the presence of tartaric or lactic acid; (2) a mixture of cresolsulphonic acids and dioxydicresyl sulphones is produced as in example 1, except that the sulphonated crude cresol is treated with crude m-cresol; the product is diluted with water and treated, at a temperature not above 45 DEG  C., with a urea-formaldehyde condensation product produced in the presence of lactic acid; (3) a sulphone-sulphonic acid mixture is produced as in example 1, except that the sulphonated crude cresol is treated with phenol, the product is added to a diluted reaction product from naphthalenesulphonic acid, 4 : 41-dioxydiphenyl sulphone and formaldehyde, and the mixture is treated with urea and a urea-formaldehyde condensation product produced in the presence of lactic acid; (4) a sulphone-sulphonic acid mixture produced as in example 1 is mixed with a diluted product from naphthalenesulphonic acid and formaldehyde, and the mixture is treated at 40 DEG  C. with a urea-formaldehyde condensation product produced in the presence of lactic acid.  Specifications 305,013, [Class 2 (iii)], and 388,475 are referred to.
