Title: Improvements in or relating to a multi-layer glass sheet
IPC: B32B17/10
Filed: 1953-01-23
Abstract: Polyvinyl acetal resin compositions are used for the interlayer of the temperature-responsive laminated glass sheets described in the parent Specification.  The acetal may be made by reacting polyvinyl alcohol with acetaldehyde, propionaldehyde, butyraldehyde, lauric aldehyde, octadecyl aldehyde, crotonaldehyde, oleylaldehyde, cinnamaldehyde, naphthaldehyde, or furfuraldehyde.  The compositions may contain methyl, ethyl, or diacetone alcohol, 2-methylpentane-2 : 4-diol, glycerine, polyvinyl alcohol, ethyl lactate or acetone.  In examples, acetals are made by treating an aqueous solution of polyvinyl alcohol with acetaldehyde or butyraldehyde and hydrochloric acid.  The precipitated acetal flakes are removed from the reaction mixture by suction filtration, washed with warm water, and dissolved in methyl alcohol to form a solution to which a hydrophilic plasticizer such as diacetone alcohol is added.  Films are cast on glass sheets from the solution, and are steeped in an aqueous solution of a hydrophilic plasticizer such as diacetone alcohol, methyl pentanediol, or glycerine.  In a further example, polyvinyl alcohol films are cast on glass plates and converted to plasticized acetal layers by treatment with an aqueous mixture of acetaldehyde or butyraldehyde with diacetone alcohol and hydrochloric acid.

Abstract: 436,491. Centrifugal classifiers. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Precipitation Co. ; 1016, West 9th Street, Los Angeles, U.S.A.) Jan. 24, 1935, No. 2399. [Class 23] A centrifugal separator for classifying solid particles in gases has a cylindrical casing 1 with a rotary impeller 2 at one end to maintain a vortical circulation of gas. An outer vortex travels from the impeller up the casing wall and an inner vortex returns to the impeller. The gas and solid particles are supplied through the inlet 3 to the funnel shaped extension 7 of the cylindrical tube 6 which carries a tube 10. The annular space 12 between the tubes 6, 10, which in the form shown in Fig. 1 is closed at the bottom, forms a discharge space for the finer material and communicates with the tangential outlet 13. The stream travels downwards through the tube 6 to the impeller and is whirled upwards near the casing wall and then moves downwards. The heavier particles are thrown out through openings 17 at the top of the casing into the box 15, and the finer particles pass to the annular space 12 and outlet 13. The openings 17 may be varied by means of a slotted plate adjusted through a hand-hole 20. In a modification, the annular space 12 is open at the bottom and closed at the top, the outlet pipe being arranged near the closed end. In a further modification the tube 10 is supported by brackets and the annular space is open at the top and the bottom. In another modification the impeller 30, Fig. 5, is at the top of the casing near the inlet which receives gas from the pipe 34 and solids from the hopper 35. Adjustable apertures 45 for the discharge of the heavy particles are arranged between the deflector cone 39 and the casing, while the light particles pass between the tubes 36, 42 to the outlet 44. The outer vortex passes down by the casing and the inner vortex returns to the fan between the tube 36 and the deflector cone 39. In a further modification the annular space for the discharge of the light particles opens into a volute discharge chamber.

Abstract: 988, 767. Finishing and tensioning yarns. HEBERLEIN & CO. A.G. Jan. 20, 1964 [Feb. 1, 1963], No. 2452/64. Headings DID and D1F. In a process for permanently crimping multifilament and staple fibre yarns of thermoplastic material e.g. a polyamide, polyester, vinyl polymer or copolymer, or polyolefin, and mixed yarns of thermoplastic fibres and non-thermoplastic natural fibres, wherein at least two yarns are plied together along a length, subjected in such condition to heat-fixing and separated again by pulling them apart at the same speed in different directions, the tension in each of the separated yarns is regulated in the immediate vicinity of the point of separation by a device the operation of which is controlled in dependence upon lateral deviations of the point from its central position. As shown in Fig. 1, yarns 1, 2, fed by rollers 3 and 4 over guides 35, 36, are plied and then fixed in a heater 45. The ply then passes through a guide 7 mounted on a lever pivoted in a horizontal plane so that, on deviation of the point of yarn separation 6, the guide engages a slidably mounted contact 8 or 9 to complete a circuit to an electromagnet 10 or 11 and thereby actuate a filament brake 12 or 13 which correctively adjusts the tension on one separated yarn or the other. The yarns then pass around guide pulleys 38, 39, 40 and 41, 42, 43, and rollers 44 and 44<SP>1</SP> carried on arms which pivot against restraining springs, Fig. 2 (not shown) to compensate for the temporarily increased tension, caused by operation of the brakes 12, 13, in the yarns passing therefrom to feed rollers 14 and 15. Several forms of electromagnetic and eddy current brakes including retarded rolleys and double discs or plates are described, Figs. 3-5 and Figs. 6-8 (not shown). In another apparatus, Fig. 9, the lateral deviation of the point 6 moves a pivoted shield 30 so that one of two apertures (as at 32) therein permits passage of light emitted from a lamp 26 on to a photocell 27 or 28, whereby a current is controlled to actuate the yarn tension regulation.
