Patent GB-442178-A (GB)
Title: Method of and apparatus for drawing glass sheets
IPC: C03B15/18
Filed: 1934-11-28
Abstract: 442,178. Glass manufacture. SIMPLEX ENGINEERING CO., Washington Trust Building, Washington, U.S.A. Nov. 28, 1934, No. 34236. Convention date, May 16. [Class 56] A method of drawing glass sheet continuously consists. in cooling the edges only of the sheet as it is drawn, while the remainder of the sheet is plastic, guiding the edges of the sheet during cooling to align the edges of the sheet with a definite line of draw, and then continuing the drawing along the determined line. The sheet is drawn upwards from a bath of molten glass B, Fig. 1, into a draw well or chamber 18 formed by vertical walls 16, and is carried thence by pairs of rollers 27 through a vertical leer 25. Pairs of knurled rollers 35 are disposed above the surface of the glass in the chamber 18 to engage the edges of the sheet and to stretch it to the desired width. Watercoolers 50 are arranged above the rollers 35 and extend across the chamber 18. In order to align the sheet with the rollers 27 and thus prevent bending or bowing of the sheet, guiding-rollers 74, 82 are provided between the rollers 35 and 27. Two pairs of the guiding-rollers are used and they engage the edges only of the sheet. They are supported by brackets secured to the sides of the draw well, the securing devices being adjustable in order that the guiding-rollers may be aligned accurately with the rollers 27. The position of the knurled rollers 35 is offset slightly with respect to the guiding-rollers 74, 82, as shown in Fig. 6, so that the glass sheet is drawn from the bath B at a slight inclination to the vertical and the edges of the sheet are held constantly against the rollers 74. The rollers 82 are free to move and are counter-balanced by weights 84, Fig. 1, so that they are pressed against the rollers 74 but adjust themselves to the thickness of the glass sheet. Means are provided for cooling the rollers 35, 74, 82. For preventing cooling of the surface of the body of glass in the bath B, shield blocks 100 extend across the width of the draw well 18 and are situated immediately above the surface of the glass. The blocks protect the glass from the chilling effect of the draw well 18 and of the leer 25. When chilled glass is to be cleaned out of the draw well 18, the rollers 35, 74, and 82 are removed, the shields 100 are raised to the upper part of the well, and the space between them is covered by a plate of refractory material. The glass in the well can then be reheated by gas flames projected into the space below the shields. The sheet may be drawn directly from the surface of the bath B, or a float or underbridge may be used at the point of drawing.

Title: Improvements in or relating to flame detection devices
IPC: F23N5/08
Filed: 1961-09-25
Abstract: 994, 639. Photo-electric flame detection. M. CLAUSEN, [trading as DANFOS VED ING. M. CLAUSEN]. Sept. 25, 1961 [Oct. 1, 1960], No. 34293/61. Drawings to Specification. Heading G1A. A flame detector comprises an element heated by or receiving radiation from the flame, and controlling a light flux in response thereto with a discontinuity in the light flux heat or radiation characteristic of the element and a photosensitive detector receiving said light. The element may be made of the oxide of one of the elements:-aluminium, beryllium, cerium magnesium, thorium, uranium and zirconium, or a mixture of such oxides, a ThO 2 /CeO 2  mixture being preferred. These forms of element are heated directly in the flame and emit light, the intensity of which suddenly increases at a predetermined temperature. If the element is to be activated by radiation from the flame rather than direct heating thereby, cadmium or zinc sulphide is used. In a further embodiment, the element is placed in the flame and its translucency measured by passing light from a source to a photosensitive detector through the element the translucency changing abruptly at a predetermined temperature.

Title: Rescidin, a new alkaloid derived from plants of the rauwolfia type
IPC: C08B13/00
Filed: 1961-09-25
Abstract: The invention comprises rescidin, i.e. the Yohimbine alkaloid of formula <FORM:0915449/IV (b)/1> and its salts with inorganic or organic acids (e.g. hydrochloric or oxalic); and a process for its preparation in which Rauwolfia extracts or mother liquors from the production of reserpine are subjected to a fractionation (fractional crystallisation, chromatographic adsorption or multiplicative separation) and rescidin isolated by crystallisation from the crude products obtained.  The examples describe the preparation of rescidin from Rauwolfia vomitoria roots.  Rescidin possesses a strong blood pressure-lowering effect, while its sedative effect is much less than that of reserpine, deserpidine and rescinnanine. Specification 744,290 is referred to.
Patent GB-818471-A (GB)
Title: Improvements in and relating to polymerisation products
Inventor: PETER MAUICE JACQUES KOCH DE G
IPC: B29C35/02
Filed: 1954-11-29
Abstract: Mouldable materials are prepared by polymerizing mixtures comprising at least two polymerizable monomeric materials, each of which when fully polymerized alone yields a thermoset synthetic resin, to an intermediate stage under conditions directly producing from the mixture a partially polymerized mass which is sufficiently stable and rigid to be stored and handled, but which can be shaped under heat and pressure, the constituents, the proportions thereof and the polymerization conditions being such that the partially polymerized material has the stated properties and can be further polymerized to an infusible form.  Preferably the mixtures contain at least one polymerizable material which when fully polymerized alone yields a thermoplastic synthetic resin.  Specified thermoset resin producing monomers are allyl methacrylate, ethylene glycol dimethacrylate and homologous glycol dimethacrylates, methacrylic anhydride, diallyl maleate, triallyl aconitate triallyl cyanurate, diethylene glycol bis (allyl carbonate) and divinyl benzene.  Specified thermoplastic resin producing monomers are vinyl acetate, allyl acetate, styrene, acrylonitrile, methacrylic acid, and methyl and homologous alkyl methacrylates.  Polymerization may be effected in the presence of catalysts, e.g. benzoyl peroxide and di-tert. butyl peroxide.  When polymerization to the infusible stage is to be catalysed by ultra-violet light benzoin type catalysts may be added.  Inhibitors, e.g. hydroquinone, 2,5-di-tert. butyl hydroquinone, di beta naphthol and tert. butyl catechol may be added to prevent premature cross-linking.  The monomer mixtures may be partially prepolymerized before pouring into moulds and heating to complete polymerization to the intermediate stage. The formation of the desired intermediate product may be detected by continuously measuring a physical property, e.g. power factor or dielectric constant, of the reaction mixture as described in Specification 818,472.  Fibres, fillers and pigments may be added to the polymerizable mixtures before solidification.  The intermediate products may be machined or softened by heating and shaped, and then cured to infusible form by further heating. Examples describe the polymerization of mixtures comprising (1), (4) and (5) diethylene glycol bis (allyl carbonate), triallyl cyanurate and methyl methacrylate; (2), (7) and (9) allyl methacrylate, methyl methacrylate and triallyl cyanurate; (3) diethylene glycol bis (allyl carbonate), triallyl cyanurate, methyl methacrylate and n-butyl methacrylate; (6) allyl methacrylate, diallyl maleate and methyl methacrylate; and (8) triallyl aconitate and allyl methacrylate.  Specifications 738,487 and 796,867 also are referred to.

Title: Improvements in and connected with photographic colour reproduction
IPC: G03B33/00
Filed: 1930-11-17
Abstract: 373,203. Colour kinematography. MUSAPHIA, G., Grosvenor House. Park Lane, London.-(Du Pont Vitacolor Corporation ; Pacific Finance Building, Los Angeles, U.S.A.) Nov. 17, 1930. No. 34563. [Class 97 (i).] A method of reducing fringing effects by persistence of vision consists in taking one or more pairs of complementary component images, the colours of successive pairs of the same group being reversed (e.g. R.G ; G.R ; R.G ; as in Fig. 8, or B.O; R.G; O.B ; G.R; as in Fig. 11) and from the negative making a colour film in which the prints of one component of each pair are superposed on the prints of the other pair (e.g. the positive films represented by Figs. 9 and 12). The component images on the positive film may be in different layers on the same side, or on opposite sides of the film base. For taking the negative a two-lens camera is used, with means for reversing the colours recorded through each objective in taking successive pairs of images, as by means of two filters 3, 4, Fig. 1. or a single rotating filter as in Fig. 3. The film is stepped with a double shift and register pins 21, Fig. 2, and a pressure plate 27 synchronously actuated from the feed mechanism. Means for centring the image when focusing the lenses is provided. The lenses 1, 2, Fig. 7, are carried by a sliding sleeve 22 and focused by a nut 23 working on a threaded sleeve 24. The nut 23 also rotates a cam 26 for laterally displacing the lens 2. In printing the positive the feed of the negative film is modified to feed two and four pictures alternatively from the negative of Fig. 8, and a registering plate 28, Fig. 5, covering two images has a registering pin 29 which completely fills a perforation on one side and a pin 30 on the other side which fills a perforation longitudinally but not laterally. This plate may if necessary be laterally reversed for printing the complementary colours, according to the printing method employed.

Title: Cells
IPC: E06B3/67
Filed: 1972-07-24
Abstract: 1402137 Double glazing unit RESEARCH FRONTIERS Inc 24 July 1972 [26 July 1971 (2)] 34600/72 Heading E1R [Also in Division H4] In a seabed cell of the type comprising two planar plates 2, 3 connected to their edges to define a volume 1 occupied by a liquid or liquid suspension, the amount of deformation of the plates when the cell is vertical, caused for example by hydrostatic pressure, is reduced by controlling the amount of liquid (and other liquid, if present) in the cell before it is sealed. Thus if a vertical cell is initially filled with liquid via a tube 6, Fig. 3, a hypodermic syringe or rubber bulb may be used to suck out liquid until the pressure at a point somewhat below the cell centre is substantially atmospheric. Some inward and outward bowing may remain, above and below the point. The liquid may also be removed by squeezing the plates 2 and 3 until they are flat. If the volume of liquid initially supplied corresponds to the undeformed volume, it is merely necessary to remove excess air by sucking or squeezing. The cell may be filled when in the horizontal position. Inward bowing of the cell may be prevented by the provision of spacers (beads or parallel elongate members) between the plates, making it possible for the pressure throughout volume 1 to be below atmospheric so that the beads are gripped between the plates. The beads, preferably of the same density as the liquid may be mixed with the liquid prior to its introduction into the cell. As particularly described, the cell is a light valve, at least one of plates 2, 3 being transparent (the other may be reflective), containing a suspension of particles in a liquid. Application of an electric field via conductive coatings 11 on the plates aligns the particles to increase the transmissivity of the suspension. If the plates were bowed as in Fig. 3, the transmission would be non-uniform due to the increased thickness and reduced field strength at the cell centre. Reference is also made to alignment of the particles by a magnetic field, but without details. When plates 2, 3 are both transparent, the cell may be useful as a window.
