Title: Antifungal antibiotic bk 217
IPC: C12P1/06
Filed: 1970-05-05
Abstract: BK 217 and its forms BK 217 alpha, BK 217 beta and BK 217 gamma and their mutants, are prepd. by cultivating a BK 217-producing strain of Streptoverticillatus cinnamoneus (pref. S. cinnamoneus NRRL 3594) under aerobic conditions in an aqs. nutrient medium until marked anti-bacterial activity is conferred on the culture by formation of BK 217, then optionally carrying out further treatment to isolate BK 217.

Title: Multi-stage distillation plant - using multiple evaporation and condensation
IPC: B01D1/26
Filed: 1972-10-17
Abstract: The stages are stacked vertically one above the other and sub-divided into two chains, interleaved, in which however a number of the individual features of all the stages are connected in one complete series. Each stage has a steam manifold from which horizontal tubes pass through an evaporation chamber to a condenser chamber, steam from this evaporator passing to the steam manifold of the next stage together with steam from a flash still into which non evaporated residue is passed from the evaporator collector sump. Multiple cross-linking is used to increase the overall yield for a given heat energy input.

Title: Analogue digital angle converter - processes demodulated signals the result being independent of frequency
IPC: H03M1/00
Filed: 1973-06-13
Abstract: An A-D angle converter, has a coder giving two analogue signals proportional to the sine and cosine of the angle to be measured, a modulator with two symmetric inputs fed by the analogue signals and two counter-dividers fed with pulses from a clocking device. The first counter-divider provides two series of square waveforms in quadrature applied to the modulation inputs of the modulator. A pass band filter at the modulator output furnishes a sinusoidal signal out of phase with the angle to be measured with respect to the first series of square waves. A pulse generator fed by the sinusoidal signal furnishes pulses out of phase with the angle to be measured regarding the first series of square waves from the first counter-divider. An output memory has its p stages connected to the second counter-divider, the coupling being controlled by the out of phase pulses.

Title: Fluid jet circulation system for solution drying - comprises concentric nozzle and shield gas with annular jets and side ducts
IPC: B02C19/06
Filed: 1973-06-29
Abstract: The drying equipment comprises an entry chamber (12) fed by a number of tangential tubes (26) connected to a collector (28) which is supplied by a flow of pressurised hot gas, such as air, superheated vapour or nitrogen.

Title: Crystalline sodium sulphate prodn - by multistage evaporation
IPC: C01D5/18
Filed: 1973-12-07
Abstract: Anhydrous Na2SO4 crystals and/or Glauber salt is made simply and economically by evapn. of Na2SO4 soln. The soln. is initially directly or indirectly cooled to 32 degrees C (i.e. to the region where solubility rises with increasing temp.) until the solubility is less than that to be encounted at the highest temp. to be used subsequently. The soln. is then heated in several stages to the inverse solubility region (i.e. solubility decreases with increasing temp.) and evapd. No build-up of scale occurs on the heat exchanger surfaces during the process.

Title: Hot water generating ship using sea's heat - condenses vapour of liquid evaporated by sea to heat stored water
IPC: F24V50/00
Filed: 1974-01-17
Abstract: The system operates on a freon refrigeration cycle. Part of the ship's hull is insulated to maintain the freon and hot water temperatures and to prevent the loss of heat back to the sea. The evaporator is situated on the outside of the hull at (4). The liquid freon is stored at (5). The refrigeration compressor is driven by a motor (6) which also drives a dosing pump (7). This pump takes condensate from (8) and feeds it to the evaporator as required. The water at (13) is heated as required to around 40 deg.C. Stirrers may be fitted to the water. Other forms of refrigeration circuits may be used.
Patent FR-2260096-A1 (FR)
Title: Sampling device for grape juices - for the determn. of the sugar content
IPC: G01N1/14
Filed: 1974-02-01
Abstract: Grape juice sampling device is for the continuous determination of the sugar content. In a vertical appts. a sampling device is placed in the path of the grapes being pressed but it is reached after some delay. A perforated drum allows only a portion of the first juice to escape to the sampling device; a certain amt. of the second juices, coming from the pressing of the pulp, also reaches the device. The relative proportions of the two types of juice sampled are identical in vol. to those existing in the crushed grapes. The exact positioning of the sampling device takes into account the path followed by the grapes during crushing under the combined mechanical action of blades, the drum and the vertical cylinder. In the case of horizontal presses, the sampling device is also placed so that only a proportion of the first juice reaches it. The wine resulting from the fermentation of the crushed grapes is more closely defined by the analysis results because the proportions of the first fluid juice and that of the second heavier juice are properly balanced in the sample.
Patent FR-2272254-A1 (FR)
Title: Grease-lubricated three-arm drilling tool - in which lubricant pressure always exceeds pressure of drilling mud
IPC: E21B10/24
Filed: 1974-05-20
Abstract: Drilling tools employ two types of lubrication, grease for rotating mechanical components and mud to cool and lubricate the cutting operation and remove refuse. In this drilling tool, grease is pressurised using hthe mud pressure by maintaining mud pressure from the hollow drilling tube on a free piston grease reservoir. A selector valve may be incorporated so that the higher of two mud pressures - i.e. before or after the drilling toll - may be used to ensure grease pressure never falls below mud pressure. Premature failure of drilling tools due to mud ingress via bearing seals may be prevented.
