Title: Biological purification of sulphurous waste liquor - using acclimatised bacteria and oxygen-contg. gas
Inventor: RIVET JEAN-JACQUES
IPC: C02F3/34
Filed: 1976-12-23
Abstract: Biological purification of sulphurous waste aq. liquors uses aerobic bacterial flora and a gas contg. oxygen. The purification is effected conjointly with that of biodegradable organic cpds., the bacteria having been acclimatised in liquors contg. biodegradable cpds. and progressively increasing quantities of S cpds. up to a concn. near that of the waste liquors to be treated. The biodegradable cpds. are pref. hydrocarbons, alcohols, polyalcohols, aldehydes, ketones, carboxylic acids, and/or animal or vegetable residual substances. The ratio of biodegradable cpds. (in grams) total oxygen demand) used, per unit of time, to sulphurous cpds. (in grams S) is >=1, pref. >=2. The S cpds. should be introduced into the waste liquor at a rate of 1-30, pref. 10-20, mg/l/day. Bacterial acclimatization and/or biological purification are effected continuously in a closed purifier fed by oxygen or oxygen-enriched gas at 5-40, pref. 10-35 degrees C with a mean dwell time of 5-10 hrs. The method is pref. conducted on liquors contg. 50-400 mg/l S. The method is applicable to waste liquors from various industrial works, such as the cracking of sulphurous petroleum. Chemical methods require a high S level, whereas bacterial methods have required a low S level in order to avoid bacterial poisoning. Acclimatisation of the bacteria solves this difficulty.

Patent FR-2342251-A1 (FR)
Title: Biological purificn. of sewage and industrial effluent - with vacuum removal of dissolved gas and bubbles before sedimentation
IPC: C02F3/22
Filed: 1977-02-25
Abstract: One of the stages involves the sepn. of gas from the waste water. The extn. of a large proportion of both gas bubblesand dissolved gas is enhanced by reducing the press. on the surface if the waste water to well below atmos., i.e., to less than 0.4 (pref. 0.3-0.1) bar. In the case of a biological purificn. process comprising oxygenation, e.g. with injected air, followed by a sedimentation stage, the gas removal stage is introduced between oxygenation and sedimentation. A further stage of flotation sepn. may be included between oxygenation and gas removal. Used in the treatment of sewage and industrial effluents, the method removes a high proportion of dissolved gas as well as gas bubbles which, alone, could be satisfactorily eliminated by mechanical agitation. The resulting, more efficient removal of gas leads to better clarification by subsequent sedimentation.
Patent FR-2388921-A1 (FR)
Title: Drying and ironing machine - with heated cylinder, press-rollers and guide tapes, gives improved ironing effect
IPC: D06F67/04
Filed: 1977-04-29
Abstract: A drying and ironing machine comprises a heated cylinder around which a textile fabric passes, entering at, and is collected, ironed and dried, in the trough. Three press-rollers, are held against the heated cylinder by laterally mounted springs. Flexible endless ribbons or tapes, sepd. from each other, are held against the heated cylinder, behind and under it, by the last of the press-rollers, and by attendant rollers. The heat-resistant tapes are distributed closely across the width of the machine, so as to be capable of handling narrow materials. The method avoids the use of a cylinder blanket, which may quickly deteriorate in the high temp. conditions generated by the heated cylinder. The replacement of the blanket by press-rollers and separate tapes provides an ironing action, which is followed by a further heat treatment, to avoid creasing before the fabric is discharged into the trough.

Title: Liq. filled timer of hour-glass type - has two different density liquids replacing granular material normally employed and has two holes in central partition
IPC: G04F1/06
Filed: 1977-05-10
Abstract: A timer or 'hourglass' is based on the use of two liquids rather than the orthodox granular material normally employed. The two liquids (2, 3) are of different colours and densities and are contained within a transparent enclosure (1) which has a central membrane (4). This membrane has two holes to allow passage of the liquids in both directions, the hole size and volume determining the time period being measured. The accuracy of the instrument is greater than that of granule types and can be used as a kitchen egg-timer or in offices to indicate the duration of telephone calls. The two holes allow flows to be established in opposite directions with the light liquid flowing up through one hole and the heavy liquid flowing down through the other hole.
