Title: Improvements in the manufacture of pile fabrics
Inventor: FUHRHOP WILHELM FRIEDRICH
IPC: D04H11/00
Filed: 1946-02-28
Abstract: 611,927. Pile fabrics. FUHRHOP, W. F., and ISSUM, J. B. H. van. Feb. 28, 1946, Nos. 6279, 7145, 16163, 16438 and 37530. [Class 142(iv)] A method of manufacturing a pile fabric consists in assembling carded or similarly processed fibrous substance in superposed layers, so that the fibres of the layers are .disposed longitudinally or approximately so, applying a consolidating medium to the fibrous layers before, during or after assemblage so that adjacent fibrous layers are separated by layers of consolidating medium, the resulting consolidated block being cut transversely of the run of the fibres into sections, a backing being applied to each section, and the consolidating medium being removed from the fibres. In the form shown, a web 1 of fibrous material is conveyed from a carding or other processing machine and after having a binding agent applied thereto by a sprayer 4 and being dried by a heater 5 is impregnated with a consolidating medium by sprayers 8 and then assembled in superposed layers 19 in a reciprocating trough 18. The block is then cut transversely into sections and each section has a backing, e.g. of plastic material applied thereto, after which the consolidating medium is removed. The fibrous substance may be stretched before impregnation with the consolidating medium. The consolidating medium may, however, be applied in the form of soluble or thermoplastic powder, flakes or sheets during the formation of the superposed layers. In a modification. the fibrous substance is divided into strands which, after being impregnated with a binding agent and dried, are wound on spools which are arranged in predetermined order in a carrier. The strands are then drawn from the spools, impregnated with consolidating medium and assembled in superposed layers. The spools may be wound with strands of different colour so as to produce a pattern in the fabric. In a further modification, the backing is rendered porous by combining with the strands of fibrous substance, filaments which resist both the consolidating medium and the backing, but are capable of being removed by a solvent after the consolidating medium has been removed. The spacing of the superposed layers may be determined by rods, or by regulating the thickness of consolidating medium supplied. Specifications 588,548 and 600,119 are referred to.

March 2, 1933, No. 6418. Convention date, March 2, 1932. [Class 38 (iii).] Travelling between predetermined limits.-A motor UVW operating, for example, a chuck, is disconnected from its supply when it is stalled for a predetermined period after unobstructedly reaching its limit of movement in one or other of its operating directions, by one of two thermally operated overload devices 12, 23, according to its direction of rotation. Closure of one of two press-buttons 1, 2, causes the corresponding forward or reverse contactor 11, 22, to close, and the operation of the appropriate overload device 12, or 23, at the limits of travel, de-energizes the closed contactor, by opening contacts 15 or 25. A third thermally operated overload device 3, operative independently of the direction of rotation, and adjusted to the motor current limit, is provided. The torque exerted by the motor when stalled may be adjusted by resistances 16, 17, shown connected for one direction of rotation only, and the periods before which the overload devices 12, 23, become effective may be independently adjusted. Each of two supply conductors to the motor may contain an overload device such as 12, 23, the two devices acting in common on the contacts 15, 25.

Title: Purification of amyloglucosidase and preparation of dextrose
IPC: C12N9/34
Filed: 1958-03-03
Abstract: Amyloglucosidase (alpha-glucosidase, glucamylase or starch-glucogenase) is purified by adding to a 50% by volume aqueous acetone solution of crude amyloglucosidase 0,25 gram. of a water-soluble inorganic neutral salt such as sodium chloride, potassium chloride or sodium sulphate per 100 ml. of the acetone solution, to precipitate the amyloglucosidase separating and washing the amylcoglucosidase, re-dissolving in 50 % by volume of aqueous acetone, adding 0,25 grm./1 ml. of said salt to precipitate the amyloglucosidase which is separated and may be dissolved in water for use in the production of dextrose from starch (see Group VI).  The crude amyloglycosidase is an aqueous extract or culture filtrate of a fungus such as Aspergillus niger. If sufficient, electrolyte is present in the aqueous extract, acetone is added to produce 50% acetone without the further addition of electrolyte.  This may be given a preliminary treatment consisting of (a) centrifugation or (b) adsorption on a water-insoluble hydrous synthetic magnesium silicate in accordance with Specification 849,509.ALSO:A process of producing dextrose from starch wherein the starch in aqueous solution is hydrolysed with amyloglucosidase, the hydrolysate clarified, concentrated, and the crystallised dextrose separated from the mother liquor, characterised in that the amyloglucosidase solution has been purified by repeated precipitation from 50% aqueous acetone by the addition of a p  water-soluble inorganic salt electrolyte such as sodium chloride (see Group IV(b)), the final hydrolysate having maximal DE values of 93 to 96% and maximal true dextrose content of 90 to 98% dry basis.  An initial purification of the amyloglucosidase may be by the adsorption process of Specification 849,509.  It is preferred to use a pure starch which has been subjected to a preliminary acid hydrolysis so that a workable fluid is obtained at a solids concentration of 25 to 50%, and especially 35%, at 45 to 60 DEG C.  A pH of 4 to 5 and a temperature of 35 to 45 DEG C, is preferred.

Filed: 1962-02-22
Abstract: 992,031. Liquid-fuel burners. ESSO RESEARCH & ENGINEERING CO. Feb. 22, 1962, No. 6938/62. Heading F4T. [Also in Divisions B2, H3 and H5] A mechanical vibrator for atomizing liquids, e.g. a fuel oil, comprises a piezo-electric plate 10 clamped between conducting mechanical resonators 12, 14, a channel being provided through one resonator 12 whereby liquid may be fed to an orifice situated at a displacement antinode of the resonator. In the arrangement shown the two resonators are both made of aluminium and have the same shape though resonators of different shapes and metals may be used provided they are both resonant at the same frequency, corresponding to the resonant frequency of the crystal. The resonators shown are of stepped cylindrical form, the steps being situated at a displacement node so that they may be clamped at that position. Clamping is effected through a narrow raised rim 36, 38 on endplates 24, 26 held together by bolts 28. Insulating layers, e.g. of polyethylene terephthalate, are placed between the raised rims and the respective resonators. The piezo-electric plate, which may be composed of a ceramic such as barium titanate, lead zirconium titanate or lead zirconate, may be silvered to improve the electrical contact between the plate and the resonators 12, 14 to which leads for applying an energizing voltage are connected. To improve the acoustic coupling between the plate 10 and the resonators 12, 14 a layer of polydimethyl siloxane in the form of silicone bouncing putty may be applied to each surface of the plate 10 (Fig. 4, not shown). The silicone putty may include finely divided silver to improve its electrical conductivity. The Specification also describes prior-art atomizing arrangements in which a ceramic piezo-electric plate is bonded by an epoxy-resin cement to the larger diametral surface of a truncated conical resonator, the concentration of energy at the tip of the resonator being sufficient to cause atomization of a liquid applied thereto.
