Patent GB-1021209-A (GB)
Title: Method and apparatus for producing glass in ribbon or sheet form
IPC: C03B18/08
Filed: 1963-07-01
Abstract: Glass is produced in ribbon or sheet form by forming a glass ribbon and moving the ribbon while supporting a portion thereof upon a liquid and a portion upon a gas, the liquid having a specific gravity greater than that of the glass and the glass being maintained in a plastic or molten state during at least a portion of its travel on the liquid and gas.  Transverse sections of the ribbon may be supported upon both liquid and gas.  The edges may both be supported by the gas or by the liquid, or one side of the ribbon may be supported by the gas and the other side by the liquid.  In Fig. 3, which is a cross-sectional view of an apparatus, ribbon 14 is supported by liquid 16 and gas from modules 65 which lie slightly below a marginal lip 66 of the liquid tank wall.  The ribbon may be heated and melted by radiant heaters 48 and by the liquid which may be heated by electrodes in the floor of the tank or submerged in the liquid and an excess pressure <PICT:1021209/C1/1> <PICT:1021209/C1/2> may be maintained by gas in the space enclosed by walls 40.  The upper surface of lip 66 is preferably of a material that is not wet by glass, e.g. graphite.  Fig. 5 shows an alternative arrangement in which lip 661 is slightly lower than the liquid level, and a fluid seal is maintained in slot 76 by gas emerging from passageways 75. The liquid is preferably molten metal, and the gas should be inert with respect to the metal. The glass ribbon may pass through a cooling zone before leaving the apparatus.  The ribbon may be attenuated, in which case the tank walls and module beds are angled to produce a tapered zone to accord with the decreased ribbon width. The gas support bed or beds may be horizontal, or may slope downwards from the liquid, or they may support the ribbon at a higher or lower level than the liquid.  By these means, the thickness of the glass in the ribbon can be caused to vary in a lateral direction. Instead of modules, a porous plate forming the top of a plenum chamber may be used to supply supporting gas.  A glass is exemplified having percentage composition by weight 71.38 SiO2, 13.26 Na2O + K2O, 11.76 CaO, 2.54 MgO, 0.75 Na2SO4, 0.15 Al2O3, 0.11 Fe2O3, and 0.06 NaCl, and specific gravity 2.542.

Filed: 1934-09-13
Abstract: 444,112. Ships' drainage. STONE & CO., Ltd., J., Deptford, and WATKINS, W. P., 54, Roseneath Road, Battersea, both in London. Sept. 13, 1934, No. 26343. [Class 113 (i)] The installation for the disposal of sewage &c. comprises a tank 1 to which the soil pipes 3, 4 and the air-vent pipe 8 are connected. At the bottom the tank is connected by a non-return ball valve 12 with the suction chamber 10 of an ejector device 11 which is connected on the downstream side by a pipe 19 with the sea and on the upstream side with a pressure source which may be an elevated water tank or a pump 41. The valve 24 controlling the pressure water supply is itself controlled by a piston 26 working in a chamber 25, the upper part of which is in communication with a water-pressure source controlled by the spring-loaded valve 28. Levelsensitive means comprising the float 36 operates the pilot valve when the tank is filled through the striker 34 and the rod 33. The release of pressure on the piston 26 permits the main valve 24 to open and operate the ejector to clear the tank.

Abstract: 986,016. Photo-electric bottled-liquid inspection apparatus. DISTILLERS CO. Ltd. May 23, 1963 [July 12, 1962], No. 26766/62. Drawings to Specification. Heading G1A. An apparatus for the detection of solid matter in a bottled liquid comprises means for inverting the bottle, a light source arranged to send a beam of light through the neck of the inverted bottle on to an associated photo-electric cell after any gas bubbles have left the liquid through which the beam passes, but before any solid matter has fallen through said liquid, and maintain said beam for sufficient time to allow any solid matter in the bottle to fall through said beam, the photo-electric cell being electrically connected to produce a signal if solid matter interrupts the beam of light falling thereon. The invention is described as applied to an apparatus, Figs. 1-3 (not shown), in which filled and stoppered bottles are transferred from a travelling conveyer to a rotating bottle inspection head and are thereafter transferred back to the conveyer and moved through a rejection gate. Each bottle is clamped in the inspection head between a base support and a retaining arm which engages the bottle top, and during the head rotation is inverted to permit the photo-electric inspection and then restored to the normal upright position ready for transfer back to the conveyer. The heat contains a plurality of inspection stations, each with its associated light source and photoelectric cell. Signals produced by the photo-electric cells are registered on solenoids which by timing means cause appropriate operation of the gate to cause the rejection of bottles containing unwanted matter.

Title: Improved process for the vulcanisation of natural rubber latices
IPC: C08J3/26
Filed: 1951-11-15
Abstract: Natural rubber latex is vulcanized by adding to it vulcanizing agents in a quantity less than 1 per cent. by weight of the dry rubber content of the latex, and then vulcanizing.  The vulcanizing agents may comprise sulphur, in the elementary form, or combined as polysulphides or dithiocarbamates and zinc oxide or similarly acting zinc compounds.  After vulcanization, the latex may be used in the manufacture of balloons which may be printed by a stamping process. In Examples, the vulcanizing agent comprises two or more substances from colloidal sulphur, zinc dibutyl dithiocarbamate, the sodium salt of the condensation product of b -naphthalene sulphonic acid with formaldehyde; zinc oxide, tetramethyl thiuram disulphide, o-tolyl biguanide, zinc dimethyl dithiocarbamate, cyclohexylethylamine salt of cyclohexylethyl dithiocarbamic acid, zinc phenylethyl dithiocarbamate, piperidine salt of pentamethylene dithiocarbamic acid, zinc diethyl dithiocarbamate, dibutylamine, mercaptobenzthiazole and diorthotolylguanidine.  After vulcanization, which may be effected at air temperature for some days, or at temperatures of 50 to 75 DEG  C., unused vulcanizing agents may be removed by a centrifuge.

[Classes 38 (iii) and 38 (v)] No volt release.-A switch for controlling an electric motor comprises a switch member 1 movable from the " off " position shown into either a " forward " or " reverse " position in which it engages contacts 16 or 1c, a "novolt " magnet 6 having an armature 5 pivoted at 16 and a link 3 pivoted to the levers 1 and 5 at 8 and 9. The switch is moved into the " forward " or " reverse " positions by pressing push buttons 11 or 12 and manual operation from either of these positions can only be effected by first pressing a push button 13 which brings the switch into its " off'' position. With parts in the position shown, pressure on button 11 or 12 first rocks the member 3 so that its pivot 8 is brought below or above the line 9, 7. Continued movement of the button causes the lever 5 to be directly engaged and turned about its axis 16 and this brings lever 1 into engagement with 1b or 1c. The consequent energization of magnet 6 completes the movement and presses the contacts firmly into engagement. Should current in the magnet 6 fail, a spring 10 returns the switch to its " off position. In the " forward " or " reverse " position, the button 11 or 12 that has not been actuated bears against a side of the link 3 and pressure on the button is without effect.
