Title: Improvements in flush tanks for water closets
IPC: E03C1/10
Filed: 1938-04-19
Abstract: 500,511. Valve-discharge water-wastepreventers. SMITH, A. J. April 19, 1938, No. 11782. [Class 26]. A valve - discharge water - wastepreventing cistem has a partition 16 6 to provide a flushing water compartment 15 and a supply water compartment 14, the water level 15<1> in the compartment 15 being below the top of the partition so that the supply water is isolated from and cannot be contaminated by the flushing water. The partition is hollow and open through the bottom of the cistern so that it cannot be removed without destroying the usefulness of the cistern. An opening 16b in the partition provides a secondary overflow above the level of the primary overflow pipe 7. The water inlet 9 is below the top of the partition so as to be sealed by the water in the compartment 14. In a modification the partition is disposed diagonally to reduce the. size of the supply water compartment. Instead of being hollow the partition may have a series of bores each with an overflow aperture. Specification 2210/13, [Class 26], is referred to.
Patent GB-450894-A (GB)
Title: Improvements in textile fabrics
IPC: D06M15/05
Filed: 1935-04-17
Abstract: Voile or similar fabric of light construction containing a cellulose ester or ether is treated with a dilute solution of a water-insoluble cellulose ester or ether having solubility characteristics different from those of the material constituting the fabric, the solvent employed having substantially no action on the material of the fabric.  The coating is preferably applied as a solution of less than 5 per cent strength.  The solvent is preferably evaporated whilst the material is maintained in a stretched condition.  The treatment may be repeated several times. The solution may be applied by padding, spraying or immersion. In an example, a cellulose acetate voile fabric is drawn through a 2 per cent solution of benzyl cellulose in benzene, and is then passed through a tenter device and the solvent evaporated.  In a further example, a voile fabric made from cellulose acetate yarn which is soluble in acetone but insoluble in chloroform, is passed through a 1 per cent solution of chloroform-soluble cellulose acetate dissolved in pure chloroform, and the chloroform evaporated; organdie fabric is obtained.  Specification 274,841, [Class 140], is referred to.

Patent GB-482849-A (GB)
Title: Improvements in or relating to stiffening material
IPC: D06M15/05
Filed: 1937-04-30
Abstract: Stiffening-material is made by impregnating a porous base material, e.g. fabric, especially flannel, felt, leather, and paper with a solution of a thermoplastic cellulose derivative wherein the cellulose derivative is near the point of precipitation and precipitating the cellulose derivative in the base material by decreasing the concentration of solvent therein. The cellulose derivative solution comprises a volatile, preferably water-soluble, solvent such as acetone, methyl acetone, methyl alcohol or denatured grain alcohol with sufficient non-solvent such as water, toluene or sulphonation products of <PICT:0482849/IV/1> naphthenes.  The cellulose derivative may be cellulose acetate or nitrate, formate, butyrate, propionate, or cellulose aceto-butyrate, ethyl, methyl or benzyl cellulose.  Precipitation may be effected by removal of solvent, e.g. by treatment with the vapour of a precipitating agent such as steam.  The solution may comprise plasticizers, e.g. camphor, triacetin, dimethyl phthalate, di-methoxy-ethyl phthalate, p-ethyl toluene sulphonamide, dibutyl tartrate and tricresyl or triphenyl phosphate, and fire retardants, e.g. hydrated calcium sulphate, ammonium phosphate, cerium oxalate and calcium tartrate.  Examples describe impregnating the base material with a warm solution and precipitating the cellulose derivative by steam injection.  A fabric 2 from a supply roll 1 passes over a guide roll 3 and round a roller 6 submerged in an impregnating solution 4 in a jacketed container 5. The fabric is led past scraper blades 9 into a precipitating chamber 8 where steam is injected into the fabric from jets 17.  The fabric then passes over guide rolls 11 through a seal 12 to squeeze rolls 13, over a tensioning device comprising idler rolls 14 and a weighted roll 141 to a drying wheel 15. Vapours are withdrawn through a vent 19 in the chamber 8.

Abstract: 882,828. Gear-cutting. PICANOL, J. April 21, 1958 [March 8, 1958], No. 12503/58. Class 83 (3). A bevel or hypoid gear-cutting machine comprises a cradle 2, and a tool-holder 5 mounted on a support 4 displaceable about an axis perpendicular to the axis of the cradle. Adjustment of the support controls the bearing area of each tooth. Reduced bearing area is obtained by reducing the angle α, Fig. 3. Mating gears can be cut by generating the pinion with reduced bearing area and form-cutting the gear without modification. The support is guided by ribs 25 and is clamped by headed bolts 13 engaged by nuts 17 formed with gear teeth. The nuts are rotated by a common gear 18 with the exception of one driving nut which is rotated directly by a bevel gear 20 by way of a squared end 23. The support is adjusted by rack-and-pinion and worm gearing against a scale 39. The support 4 may have a spherical bearing surface. Specification 882,827 is referred to.
