Title: Process for manufacture of milk sugar
IPC: C13K5/00
Filed: 1947-08-01
Abstract: Lactose is manufactured from whey or other lactose containing lacteal fluids by evaporating preferably under vacuum the latter to form a concentrate supersaturated with respect to its lactose content which may be momentarily heated to 220-260 DEG  F. by direct contact with steam and permitting approximately 20-40 per cent of lactose to crystallize, adding sufficient water which may be sufficiently cold to minimize re-solution of lactose crystals (or other aqueous materials such as whey) to the concentrated slurry of crystals and mother liquor to reduce the viscosity then removing the lactose crystals from the diluted slurry by passing it into a classifying cone where the crystals collect at the bottom and the liquid overflows at the top, the latter being utilized in the manufacture of animal foods (see Group I).  The crystallization may be helped by seeding with crystals formed in a preceding batch of the process.  In another procedure the batch is crystallized over a suitable period and without removing any crystals it is mixed with the next batch of concentrate and the combined material further crystallized.  Other batches may be added depending in tankage capacity.  Specifications 448,539 and 530,827 are referred to.ALSO:Lactose is manufactured from whey or other lactose-containing lacteal fluids by evaporating preferably under vacuum the latter to form a concentrate supersaturated with respect to its lactose content which may be momentarily heated to 220 DEG -260 DEG F by direct contact with steam and permitting approximately 20-40 per cent of lactose to crystallize adding sufficient water which may be sufficiently cold to minimize re-solution of lactose crystals (or other aqueous materials such as whey) to the concentrated slurry of crystals and mother liquor to reduce the viscosity, then removing the lactose crystals from the diluted slurry by passing it into a classifying cone when the crystals collect at the bottom and the liquid overflows at the top, the latter being utilized in the manufacture of animal foods (see Group I).

Title: A new antibiotic phyllomycin
Filed: 1958-07-07
Abstract: <PICT:0864814/IV (b)/1> <PICT:0864814/IV (b)/2> A new antibiotic phyllomycin is produced by aerobically cultivating a phllyomycin-producing strain of Streptomyces umbrosus nov. spec. in an aqueous culture medium containing a source of carbon, nitrogen and inorganic salts.  Submerged cultivation is preferred, the initial pH is 6,5 to 7,5, the temperatures 26 to 32 DEG C and the duration 3 days.  A typical aqueous nutrient solution contains glycerol, brewer's yeast, glycocoll, sodium chloride, potassium mono-hydrogen phosphate, ferrous sulphate and magnesium sulphate.  Phyllomycin is found mainly in the clarified culture broth from which it can be isolated by (a) solvent extraction and (b) adsorption.  Extraction may be by ethyl acetate, butyl acetate, chlorinated hydrocarbons e.g. chloroform, ethers, ketones and alcohols.  The extract is concentrated, insolubles precipitated by a hydrocarbon such as petroleum ether, the hydrocarbon solvent removed, the residue taken up with an alcohol such as methanol and the antibiotic recovered from the methanol solution.  Further purification may be obtained by counter-current distribution with a system consisting of 13 parts ligroin, 6 parts butyl acetate, 2 parts di-n-butyl ether, 14 parts N-dimethyl formamide and 7 parts water. Alternatively, the clarified broth may be treated with active carbon and the antibiotic eluted therefrom with an organic solvent such as chloroform or alcohol. Phyllomycin has bacteriostatic and fungistatic properties especially against plant fungi; it forms p  needles arranged in rosettes m. pt. 177-178,5 DEG C.; [a ]21D = 75 DEG C.

Abstract: 1,205,662. Rolling gears. LANDIS MACHINE CO. 17 Jan., 1968 [27 Feb., 1967], No. 22017/69. Divided out of 1,205,661. Heading B3M. An apparatus, suitable for loading and unloading hollow gear blanks W from a turret 130 associated with a pair of die rolls 22 and 24, includes an entry hopper 282, an exit hopper 284, and an axially movable slide disposed between the hoppers. The slide is hydraulically operated and includes side plates 312 and 314 which are shaped to correspond to the contour of a blank. When the plates are withdrawn from the position shown, a blank is pulled from the mandrel and is allowed to fall down the hopper 284. The staggered relationship of the hoppers prevents blanks from passing directly from the entry to the exit hoppers. As the plates are moved towards the mandrel a new blank falls into the shaped gap between the plates and is fed on to a further mandrel 146. The mandrels are mounted on a turret which is indexed through 90 degrees between rolling steps, the loading station being opposite the rolling station.

Patent GB-1577650-A (GB)
Title: Coupling and method for connecting two tubular members by welding
IPC: F16L47/03
Filed: 1977-05-25
Abstract: The coupling of two tubular elements is achieved by welding them together by energization of an electrical resistance element, the one element comprising a male end, the other a socket end. The coupling operation is carried out by means of a composite connecting piece comprising two rings which are fitted on one another, one acting as a support for a bifilar electrical resistance element and the other as a sheath. The electrical resistance element is thus uniformly coated in plastic material and is accurately centered, thereby ensuring uniform heating and welding. This coupling method is for use in coupling discharge pipelines for waste water and rain water and for conduits for industrial fluids.

Title: Means for preventing pulsation in electric motors
IPC: H02K23/24
Filed: 1926-09-09
Abstract: 258,273. Siemens - Schuckertwerke Ges. Sept. 10, 1925, [Convention date]. Exciting; commutating windings; motors, controlling.-To prevent pulsations in motors which work with a series characteristic in one direction and a shunt characteristic in the other, two opposing series coils of different strengths are employed, the stronger of which alone is used in one direction to impart a series characteristic while the weaker one is used as an anti-pulsation coil when the motor is running in the reverse direction with a shunt characteristic. The weaker coil may be formed by carrying the connectors of the commutating windings past or around the main poles and the stronger one is cut out or short-circuited when the rotation is reversed. Fig. 1 shows a form in which both main and commutating poles have complete numbers of turns and Fig. 2 shows a simplified and magnetically equivalent arrangement in which the connectors of the commutating- pole windings are used for the main excitation by being carried past the main poles instead of around them. In the form shown in Fig. 3, each commutating pole has one and a half turns and each alternate main pole one turn. The Specification describes an equivalent arrangement to Fig. 3 with the simplification given by carrying the connectors of the commutating-pole windings past the main poles in the manner illustrated in Fig. 2.
