Patent GB-562402-A (GB)
Title: Process of preparing ion exchange compounds and compounds made thereby
IPC: B01J41/12
Filed: 1941-10-02
Abstract: Anion exchange compounds are formed by co-condensing urea and/or an aminotriazine and biguanide or a biguanide salt with formaldehyde, forming a gel of the resulting product, grinding the gel, drying it and curing it.  The term urea is defined as including thiourea and alkyl ureas, and the term aminotriazine as including melamine and similar compounds, e.g. 2,4,6-triethyl and triphenyl triamino-1, 3,5-triazines, 2,4,6-trihydrazino-1,3,5-triazine, the guanamines, e.g. formoguanamine, and lauroguanamine and 2-amino-1,3,5-triazine or commercial mixtures of the various aminotriazines, for example, the product obtained by heating dicyandiamide sufficiently to obtain some melamine together with other reactive aminotriazines. Biguanide may be used as the nitrate, sulphate, carbonate, acetate, formate, phthalate, benzoate and chloride.  The molar ratio of biguanide to urea should preferably be between about 1 : 1 and 1 : 4 and to aminotriazine between about 3 : 1 and 1 : 3. p  Examples 1 to 6 describe the preparation of ion exchange compounds from a mixture containing urea, biguanide salt, sodium carbonate and formaldehyde. The mixture is refluxed on a steam bath, the gel precipitated by addition of acid, ground and dried.  The ground material may be washed with a dilute alkali, followed by water and is then dried and cured by heating.  Example 7 describes a similar preparation using biguanide.  In this case no sodium carbonate is present and the addition of acid is unnecessary for the formation of the gel. Examples 8 and 9 describe similar preparations using melamine in place of urea.  The products are useful for water softening, removal of acid from water or alcohol solutions or the purification of sugar juices.  They have a capacity for extraction of acid from fluid media, equivalent to 7,000 to 20,000 grains of calcium carbonate per cubic foot of resin.  Filter beds consisting of the products may be regenerated after exhaustion by washing with dilute alkali followed by distilled water.  Specification 561,896 is referred to.  The Specification as open to inspection under Sect. 91 describes also the use with urea and/or aminotriazine of acetaldehyde, propionaldehyde, butyraldehyde, or furfural in place of formaldehyde.  It also states that phenol- or cresol-formaldehyde condensation products may be used in place of the urea-aldehyde or aminotriazine-aldehyde resin and that phenol, aniline, phenylene diamine, dicyandiamide, guanidine and its salts or derivatives may be used with the biguanide or biguanide salt.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of linoleum or like material
IPC: D06N7/00
Filed: 1928-05-02
Abstract: 316,646. Linoleum Manufacturing Co., Ltd., and Godfrey, A. A. May 2, 1928. Flooring-tiles.-In the manufacture of linoleum tiles for floor covering, tesserae which are intended to represent tiles or wooden blocks are provided with edges of differently coloured material to represent mortar or glue by the following method. A number of tesserae 1, Fig. 4, are superimposed, with thin sheets 2 of metal or other hard material between them, the latter projecting slightly beyond the edges of the tesserae. A sheet of the material representing the mortar or glue is then pressed on to the edges and is cut through by the metal sheets, leaving borders 3, Fig. 5, on the tesserae, which are then separated. In another method, a strip of linoleum material 1, Fig. 1, is rolled up with a strip 2 of metal slightly wider than the linoleum. A sheet of material is then pressed on the ends of the roll, and is cut through by the projecting edges of the metal. A border is thus formed on the edges of the linoleum strip. The latter may then be cut up to form rectangular pieces, bordered on two sides, and then placed on the metal strip with the bordered sides in contact, as shown in Fig. 2, rolled up again, and further borders applied as before.

Title: Streptogramin and process for production
IPC: G01N33/487
Filed: 1955-05-04
Abstract: A new antibiotic, streptogramin, is produced by growing a streptogramin-producing strain of Streptomyces graminofaciens nov. spec., especially S. graminofaciens ATCC 12705, in a culture medium containing assimilable sources of carbohydrate (e.g. glucose, dextrin or starch), nitrogen (e.g. tryptone, soypeptone and monosodium glutamate) and inorganic salts (e.g. sodium chloride, potassium hydrogen phosphate, potassium dihydrogen phosphate and manganese chloride) under aerobic conditions.  A temperature of 25 DEG  C., an initial pH of 6.7 to 7.0 and <PICT:0776035/IV(b)/1> a duration of cultivation of 4 days is employed.  The antibiotic is recovered from the filtered broth by solvent extraction with ethyl acetate.  The ethyl acetate extract is washed with (a) phosphate buffer of pH 9.0; (b) acetate buffer of pH 3.5; and (c) water to remove impurities. The extract is then concentrated in vacuo and ligroin added to precipitate the streptogramin.  Further purification is obtained by dissolving in methanol, adding phosphate buffer of pH 7.0, allowing to stand at 5 DEG  C. for 18 to 24 hours, removing the precipitate and concentrating the filtrate to recover the antibiotic. Streptogramin is a neutral substance of empirical formula C26H33N3O7; it is readily soluble in methanol, ethanol, acetone and ethyl acetate, sparingly soluble in water insoluble in ligroin, has a metlting-point of 155 DEG  C. and a specific rotation of [a ]25 DEG D = - 134 DEG .  Shows the following distinguishable adsorption bands in the infra-red: 3.05, 3.43, 3.54, 5.80, 6.02, 6.17, 6.23, 6.35, 6.46, 6.58, 6.94, 7.03, 7.32, 7.46, 7.64, 7.72, 7.96, 8.09, 8.20, 8.44, 8.61, 8.94, 9.45, 9.65, 9.78, 10.15, 10.26, 10.60, 10.80, 10.98, 10.29, 11.50, 11.78, 12.28, 12.68, 13.00, 13.23, 13.40 and 14.35 microns.

Patent GB-495063-A (GB)
Title: Process for producing water gas or gases containing water gas
IPC: C10J3/00
Filed: 1937-05-07
Abstract: 495,063. Water-gas generation. VOLK, F. May 7, 1937, No. 13139. [Class 55 (i)] In a process for producing water gas, or gases containing water gas, and in which two or more generators are employed, the zone passed by the water gas immediately before discharge from the second generator in the series is the hottest zone in the gas generating period. Each generator may be provided with a heat regenerator. The object is to convert any tar or hydrocarbons into carbon monoxide and hydrogen, any carbon dioxide being reduced to carbon monoxide. When generator 1 is being air blasted by fan 3 and pipe 12, the hot blast gases are burned in regenerator 2 and discharged through conduit 7, and during this period, water gas is made in generator 1<1> by admitting steam from above through pipe 8<1> and regenerator 2<1>, the water gas being withdrawn from below through pipe 91. When generator 1 is heated, steam is supplied to generator 1<1> from below through pipe 11<1> and the water gas and distillates pass through regenerators 2<1> and 2 and down through generator 1, the tarry vapours being decomposed and the gases escaping through pipe 9. When the fuel in generator 1 is sufficiently cooled the steam from pipe 11<1> is cut off, conduit 10 is closed, and steam admitted through pipe 8 to regenerator 2 and down through generator 1, a hot blast period being started in generator 1<1>. Water gas generated by admitting steam below generator 1 then passes through regenerators 2, 2<1> and down through generator 1<1>. In a modification three generators with their respective regenerators may be employed in a cyclic manner.

Title: A half volute for a low-pressure kaplan turbine
IPC: F03B3/18
Filed: 1957-04-26
Abstract: 813,298. Hydraulic turbines. VOITH G.m.b.H., J. M. April 26, 1957 [April 30, 1956], No. 13329/57. Class 110 (3). In a half volute for low head Kaplan turbines comprising an entry chamber followed by a half volute chamber, a spur located between the entry. chamber and half volute chamber and a set of circularly disposed fixed stay vanes, the spur is a thin elongated tongue, the length of which is about 10 to 25 times and preferably about 20 times its average thickness which is approximately uniform throughout the greater part of its length and the stay vanes on the entry side of the spur produce a substantial increase in the tangential component of the flow velocity. The sections 3; 4 on either side of the entry chamber 1 into which the water is uniformly and linearly delivered in the direction of the arrow 2 have convex walls which merge, on the volute side, into a concave section 5 and on the spur side, into a concave section 6 of high curvature. The volute chamber 7 is so designed that, from the inlet section i to the section e the mean tangential velocity of flow increases. From section e to section c there is a gradual but not substantial decrease in mean tangential velocity of flow whereas in the final portion from c to a there is a rapid and substantial increase in tangential flow velocity. The spur 8 is thin and elongated and over the major part of its length of the same thickness. The length is approximately 15 times its thickness. The stay vane 9 of the fixed stay vanes 9 to 20 has the greatest curvature and the curvature of the following stay vanes diminishes until stay vane 13 is reached which has a very slight positive curvature. The chordal length of the stay vanes also gradually diminish, that of stay vane 9 being approximately three times that of vane 13. When higher pressure heads are used an additional stay vane may be placed between the vanes 10, 11. The vanes 14 to 20 have a negative curvature which increases from vane 14 onwards but this armature is small compared with that of vanes 9 to 11. The curvature of the vane 9 and the curve with which the entry chamber merges into the spur 8 should be matched so that a gradually tapering nozzleshaped duct is formed. A similar shaped duct should also be formed between the vanes 9, 10. The vanes on the entry side of the spur. may be designed as slotted aerofoils or as, staggered profiles. The roof and floor of the entry chamber in the entry region of the spur 8 are arranged to produce a nozzle-like duct entry into the stay vane ring.

Abstract: 371,174. Washing granular materials. HOYOIS, L., 92, ChaussÚe de Ransart, Gilly, Belgium. May 6, 1931, No. 13413. [Class 82 (ii).] Particles to be separated are passed in a current of liquid down a slightly inclined trough having one or more openings in the bottom through each of which an obliquely ascending stream is passed, the stream being convergent throughout its ascension so that the heavier particles which fall through the openings meet progressively decreasing current velocities as they descend. Particles are passed down a trough 1 in a current of water issuing from a valved pipe 3 until they reach an opening 2 in the bottom of the trough. Below the opening is a box 4 with a valved water inlet 5, the bottom of the box either forming a sump in which works a conveyer 6 or being provided with a valved discharge opening, in which case an additional water inlet 15 is provided. The water entering at the inlet 5 passes to the opening 2 in an obliquely ascending converging stream, being guided by partitions 7, 8, connected to the upstream and downstream edges respectively of the opening 2. A curved dam 9 is provided at the downstream edge of the opening, the curvature being such that the partition 8 is tangential to the dam at the point 10. The partitions 7, 8 are preferably hinged to the trough, Fig. 3, so that their inclinations may be independently adjusted by connections 12 and the partition 8 may be connected to a movable section 13 of the trough so that the size of the opening 2 can be adjusted. The process is particularly applicable to the separation of particles the specific gravities of which only differ very slightly, for example to the separation of the middling product obtained in coal separation. The feeding of the particles to the current in the trough is preferably adjusted so that the particles are presented individually to the action of the obliquely ascending current.
