Title: Improvements in or relating to the manufacture of sheet glass
IPC: C03B15/02
Filed: 1934-02-10
Abstract: 427,355. Glass manufacture. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Byrnes, C. P. ; Sewickley, Pennsylvania, U.S.A.) Feb. 10, 1934, No. 4505. [Class 56] A method of making sheet glass consists in drawing a sheet upwards from a bath of molten glass through an enclosed, partly enclosed, or shielded atmosphere until the surface of the glass has set sufficiently to prevent marring by contact with a solid, and then drawing the sheet over a cooler guiding surface in the enclosed space, the draw being continued at an angle to the plane of the part of the sheet below the guiding surface. The sheet s. Fig. 1, is drawn from a forehearth 2 into a chamber 5 formed by a pair of transverse arches 3, 4 which dip into the molten glass. The lower edges of the arches are curved and are submerged to a greater extent at their middle portions than at their ends in order to equalize the temperature of the glass across the whole of the width from which the sheet a is drawn. The drawing chamber 5 contains coolers 11, and guiding- members 18, 19 which prevent the meniscus c of the sheet from moving about. The guides are arranged at such a distance above the surface of the molten glass that the sheet becomes set before it makes contact with the guides. Preferably, the guides consist of rollers which are kept at a dull red heat by circulating air through them. They are rotated either in the same or in opposite direction to the movement of the sheet s, but in any case, they move at a different speed from that of the sheet so that they exert a wiping action on the glass. The temperature of the glass in the forehearth is so controlled that the sheet remains in contact with one of the guides preferably the roller 18. The meniscus tends to approach the outer arch 4, and the parts of the sheet s above and below the roller 18 are not in the same plane. The sheet s after leaving the guides, is drawn through a leer 21 of the Fourcault type by rollers 20. In a modified construction, the roller 19 is arranged at a higher level than the roller 18 and at such a distance apart that the sheet makes contact with both rollers. In this case, the sheet is deflected slightly as it passes the rollers. In all cases, watercooled pipes 22, 23 are arranged above the rollers and near to the sheet in order to complete the setting of the glass. Each cooler 11 consists preferably of an elongated box along the upper part of which a pipe 27, Fig. 6, extends. Water enters the pipe 27 and escapes through perforations, the inner end of the pipe being plugged. The water is distributed along the length of the box and is drawn off through an outlet pipe 28.
Patent GB-348677-A (GB)
Title: Improvements relating to metal vapour lamps
IPC: H01J61/58
Filed: 1930-02-11
Abstract: 348,677. Metallic-vapour lamps. STAMMREICH, H., 1A, Schwarzburgallee, Neuwestend, Berlin. Feb. 11, 1930, No. 4538. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 12, 1930.] [Class 39 (i).] Vapour arc lamps having electrodes of an amalgam or other alloy liquid during operation are operated so that the constituents of the alloy separate and a constituent not desired in the arc is removed from the arc space, the difference in the specific gravities of the constituents being used in effecting or maintaining the separation. In a lamp with an electrode of zinc or cadmium amalgam, the mercury is removed to the part of the electrode remote from the arc and an arc in zinc or cadmium vapour is produced. A large lamp with a glass envelope may have one amalgam electrode 56, Fig. 1, and one electrode 57 of tungsten or carbon, the mercury being condensed in the chamber 54 and returning at once to the bottom of the electrode 56 through the pipe 55. In a modification, the lamp has two amalgam electrodes and the mercury is condensed in two chambers or in a single chamber. In the latter case, the pipes leading back to the electrodes are of cross section, or have nozzles of cross section, corresponding to the quantity of mercury to be fed to each electrode. In a lamp giving a point source of light, Fig. 3, the lamp is rotated about an axis 60 and the mercury 58 in two or three electrodes separates out by centrifugal force. Starting is effected by a high-tension current impulse. Specification 294,172, [Class 39 (i), Electric lamps, Arc &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also amalgam lamps in which the more volatile constituents of the amalgam are collected in one or more receivers instead of returning to or remaining at the electrode, and describes the two lamps of Figs. 1 and 2 of Specification 294,172 and modifications. Figs. 4 (Cancelled) and 3 (Cancelled) show modifications of these two lamps respectively. In Fig. 4 (Cancelled), the receiver 44 for condensed mercury is pearshaped and an electromagnet and lever system are provided to retain the lamp in the position shown during operation and to allow it to tilt after operation to empty the receiver 44 into the tube 38. In Fig. 3 (Cancelled), two valves 32, 33 are operated by a single electromagnetic armature 30 and one valve only is closed at a time, mercury vapour passing to the cooling worm 29 and the condensate collecting in the receiver 26 when the valve 32 is closed. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 336,208, [Class 39 (i), Electric lamps, Arc &c.].

Title: Improvements in or relating to cam-mechanisms
IPC: F01L1/04
Filed: 1924-02-22
Abstract: 235,927. Venning, F. H. W. Feb. 22, 1924. Cam mechanism functioning only during alternate rotations. A member which is adapted to rock about an axis parallel with the axis of rotation, constitutes the sole effective cam surface and is operative in either direction. The rocking member may be carried either by the rotary or the stationary part and co-operates with a wiper or follower which during successive rotations rides alternately over and under the rocking member, at the same time tilting it into the requisite position for the successive rotation. In Figs. 1 and 2, the invention is shown applied to a singlecylinder internal-combustion engine in which inlet and exhaust valves are actuated during alternate rotations of the crank shaft 1, the valve tappets 8, 9 being lifted for this purpose by bell cranks 10 operated by the cam members. The rocking cam members 4, 4<1> are pivoted respectively to flanges 3 of a boss or sleeve 2 fixed to the shaft, and are held tilted in either direction by springs 6 drawing upon arms 5 on the pivots. In the position shown in Fig. 1, a pin or roller 12 upon the bell crank 10 is about to ride over the rotating cam member 4 to actuate one of the valves. In its passage it tilts the rocking member so that during the succeeding rotation it enters the gap between the rocking member and the shaft and resets the rocking member. In Fig. 3, the invention is shown applied to the contact-breaker of a magneto adapted for direct coupling to a crank shaft. The rotating magneto part 13 carries a lever, the arms 10, 10<1> of which have a limited amount of relative play. The arm 10 forms the working element of the contact breaker a, whilst the arm 10<1> carries a pin or roller 12<1> adapted to bear against the inner wall 13<a> of a stationary annular casing. At one part of the wall a recess or enlargement 13b is formed within which the rocking cam member 4<1> is pivoted being retained in either tilted position by a spring. In the position shown, the roller 12' has just tilted the cam member during the idle rotation in clockwise direction so that during the next rotation the roller will pass into the recess 13b.

The aminoplast may be etherified with a C1-C4 alcohol.  The composition may be applied to the fibres, filaments or yarn before fabrication but is preferably applied to the preformed fabric.  Application may be by spraying, brushing, dipping, padding or roller coating.  An aminoplast curing agent (many specified) is applied to the fibres before, simultaneously with or after the composition is applied, the preferred curing agents being zinc fluoborate and zinc nitrate. After application excess of the aqueous composition is removed, the treated material is dried and the aminoplast composition is used by heating it to 220 DEG -450 DEG F. (e.g. by heated air currents, infra-red radiation or high frequency electric induction). Examples describe the treatment of a white cotton fabric.
