Abstract: 1389882 Phosphorus-containing condensation products CIBA GEIGY AG 5 Sept 1972 [10 Sept 1971] 41103/72 Addition to 1324628 Headings C3R and C3F [Also in Division D1] Polycondensation products are obtained by condensing at 10‹ C. to 100‹ C. (a) a self-condensation product of a tetrakis-(hydroxymethyl)-phosphonium salt or hydroxide having units of formula with (b) an amide and/or amine. The selfcondensation product (a) is obtained by condensing an anhydrous tetrakis-(hydroxymethyl)- phosphonium salt or tetrakis-(hydroxymethyl)- phosphonium hydroxide with itself in an anhydrous medium, optionally with an acid catalyst and optionally in an organic solvent, at 100‹ C. to 150‹ C., with the condensation being continued until 0À5 to 1À5 mols. of water have been separated off per 1 mol. of phosphonium compound, optionally etherifying free hydroxyl groups with an alkanol and optionally converting the salts of the self-condensation products into the corresponding hydroxides. The condensation of (a) with (b) may be carried out in a water-soluble organic solvent or in water with 1 to 15 parts by weight of (a) per 1 part by weight of (b). Textiles, wood, paper, furs or hides may be flameproofed by applying to them aqueous compositions containing the polycondensation products together with polyfunctional epoxides or nitrogen compounds, and then drying and heating the materials. The polycondensation products may be incorporated into plastics materials and into fibre spinning compositions to render them flameproof. In examples selfcondensation products of tetrakis-(hydroxymethyl)-phosphonium chloride are condensed with urea, melamine, guanidine carbonate, 3- (dimethylphosphono)-propionic acid amide, acrylamide, cyanamide, 2,4,6-tribromoaniline and stearylamine; some of the products so obtained are incorporated in viscose compositions from which fibres are spun and made into fabrics, and some are made into aqueous compositions with dimethylolamine and applied to cottonpolyester and to woollen fabrics, and with pentamethylolmelamine-dimethyl-ether and applied to a cotton fabric, the fabrics being dried and heated to cure the polymers.

Title: A device for aerating fermenting liquid
Inventor: KERSTING HANS
IPC: B01F7/00
Filed: 1964-10-13
Abstract: Apparatus for aerating a fermenting mash, especially in the production of bakers' yeast, comprises a container 2 having a central air supply pipe 4 with a diffuser head in the form of porous hollow bodies 5 radiating from it in fan-like arrangement as shown, or helically.  Fresh liquor and additives are continuously supplied at 24, 25, 26 and yeast is continuously withdrawn at 29, the aerated mash circulating through pipes 19, 20.  The diffuser head may be rotated by (a) the reaction of the air issuing from the vertical faces of the hollow bodies, (b) the action of liquor emerging from the pipe 20 which is directed tangentially on to the diffuser head, or (c) the action of the incoming and circulating liquids on the bucket wheel 21 transmitted by suitable gearing. When aeration is stopped the diffuser head is raised out of the liquor (to prevent clogging by mash particles) by a counterweight 30.  In operation the diffuser is automatically lowered by pressure of the aerating air in the cylinder 40 on the counterweight.  There is a cooler 16. <PICT:1032189/C6-C7/1>

Abstract: 1433161 Liquid epitaxial deposition SEIMENS AG 6 Sept 1973 [28 Sept 1972] 42035/ 73 Heading B1S An epitaxial layer is formed on a substrate of the same material by bringing the melt into contact with the surface of the substrate at such a temperature that the substrate is insoluble in the melt, heating the melt, whilst in contact with a cover for the melt, to dissolve the surface of the substrate and subsequently lowering the temperature of the melt so that the melt and material dissolved therein are epitaxially deposited on the substrate. The cover preferably floats on the layer of liquid phase material. The cover may be provided with one or more apertures through which dopants from the gaseous phase may be supplied to the melt. The layer is preferably formed in a recess in a carrier body. The recess may be provided with an overflow space. Suitable apparatus for carrying out the method is shown in Fig. 4 and comprises a cover 46 supported on a carrier body 44, the cover 46 containing a number of apertures 461 through which the material of the melt 41 can be introduced into the space between the carrier body 44 with the substrate wafer 3 and the cover 46. If the material of the melt has already been introduced into this area, any excess melt will be pushed out through the apertures 461 as a result of the pressure of the cover. Gaseous dopants can be used to penetrate into the melt 46 for incorporation in the epitaxial layer grown on the surface of the wafer 3.

The side parts 8 (Fig. 1) and 9 (Fig. 2) are each reinforced at their upper edge by a tubular section provided with carrying handles 11. Side parts 8, 9 are held in forks 5 by the pegs 7 whilst the lower edges of the side parts fit behind the longitudinal beams and are supported against these beams. Carrying tubes 13 may be introduced into the ends of tubular sections 10. As shown in Fig. 5, an additional stretcher may be constructed by removing the side parts 8, 9 and connecting them .together by means of cross bars 16.

Steam (or other vapour), containing a small proportion of air, is condensed in a condenser comprising a plurality of tubes for the passage therethrough of cooling fluid, wherein the tubes are arranged in groups to define a main condenser part 11, a secondary condenser part 12 and an air cooler 13, each group being separated from the adjoining group(s) by a space 14, 15 devoid of tubes, and the secondary condenser part being arranged so that the cross-sectional area of the flowpath for the steam progressively decreases in the direction of steam-flow 6. The arrangement is such that the velocity of the steam through part 12 is about the same as the velocity of the steam leaving part 11; and that the air leaves part 11 with a partial pressure of 0.1% of the total pressure, and leaves part 12 with a partial pressure of about 1.0% of the total pressure. Alternative designs of condensers are exemplified wherein guide plates are fitted between the main part and secondary part of the condenser, and between the secondary part of the condenser and the air cooler.

Abstract: 1,154,711. Multiplex pulse code signalling. H. M. POSTMASTER GENERAL. 7 Oct., 1966 [13 Oct., 1965], No. 43445/65. Heading H4L. In a digital communication system in which incoming "bits" are stored and subsequently read out by locally generated pulses to absorb timing errors arising in transmission as in Specification 1,130,401, the master oscillator is additionally synchronized with those at remote stations by D.C. signals developed from locally and remotely generated error signals. Pulses P1-P8 generated a time determined by a synchronizing bit in the incoming signal, and t1-t8 generated by the local master oscillator applied to the input and output "and" gates respectively of store LDS, Fig. 3, are applied also to a toggle TR1 and the output is integrated to produce an error signal, which is then amplified and applied through a filter EF to a frequency correcting network EO. Out of synchronism signals from a remote station are decoded into D.C. signals, and applied conjointly with the local error signal to the amplifier LDA through integrating network INT 3. The local error signal is encoded in a circuit LC including a toggle circuit LCT and sent to the remote station or stations as a preponderance of "0"s or a preponderance of "1"s The system may use time-division multiplex pulse-code modulation to transmit speech and is described in connection with interconected telephone exchanges, the arrangement including a crosspoint switching network which may include slot changing facilities. Fixed delay is incorporated at the exchanges so that the transmission delay corrected by the fixed delay plus half the variable delay, equals an integral number of line frames.
