Title: Improvements in methods for the continuous drawing of glass and apparatus for effecting the process
IPC: C03B15/02
Filed: 1953-02-13
Abstract: 724,676. Glass drawing. COMPAGNIES REUNIES DES GLACES ET VERRES SPECIAUX DU NORD DE LA FRANCE. Feb. 13, 1953 [Feb. 16, 1952], No. 4143/53. Glass 56. In the continuous drawing of sheet glass, in order to increase the drawing speed a skin of high viscosity is formed at the drawing surface whilst the glass within the thickness between the skins remains at low viscosity, the glass having to be drawn at a high speed to carry the low viscous glass along with the skins. The highly viscous skin is formed by convection e.g. by forced air currents directed towards the drawing surface, or by the contact with the glass of a cool body not wetted by the glass. Local heaters may be pro-  vided to maintain the low viscosity of the glass which is to fill the space between the skins. Several forms of apparatus are described, that shown in Fig. 3 for example comprising chambers 7 for blowing and removing cooling air for forming the skins, and local heaters 23 for maintaining the low viscosity of the glass between the skins. Cooling radiators B are provided for subsequently making firm the glass between the skins.

Title: Process for separating normal paraffins from hydrocarbon oils
IPC: C10G25/03
Filed: 1959-02-09
Abstract: A process for separating normal paraffins from a hydrocarbon oil comprises passing said oil at least partly in liquid phase downwardly through a foraminous bed of stationary granules of a molecular sieve adsorbent of about 5 Angstrom pore diameter, at a temperature in the range from 300 DEG -500 DEG C., simultaneously with an inert fluid in the vapour phase at the rate of at least 50 cubic feet of inert fluid per barrel of oil, and withdrawing an oil of lowered normal paraffin content from said bed.  Treated oils preferably have a relatively low wax content; they may first be partially dewaxed by a conventional solvent dewaxing process using, for example, a mixture of an aromatic hydrocarbon and methyl ethyl ketone.  Asphaltic oils are preferably first deasphalted by means of liquid propane.  The molecular sieve preferably has uniform particle size in the range 1/16 to 1/4 inch average diameter.  Inert fluids specified are nitrogen, hydrogen, carbon dioxide, methane, ethane, propane, and light hydrocarbons volatilized from the treated oil under the conditions in the treating zone.  Suitable process conditions are a pressure of 0.1 to 100 atmospheres; a feed rate of 1/2 -4 volumes of oil per volume of adsorbent per hour; and an inert fluid to oil ratio of 250-1000 cubic feet of gas per barrel of oil.  The adsorbent may be regenerated with an oxygen-containing gas at 400-550 DEG C. or by desorption using a liquid normal hydrocarbon.  Examples illustrate application of the process to a variety of feed oils and the effect of variation of process conditions.  Lubricating oil compositions.  Example VIII and IX show that oils treated according to the invention are more sensitive to conventional pour point depressants, such as polyalky methacrylates and alkylated polycyclic aromatics, than oils not so treated.  Example X shows that a bright stock dewaxed according to the invention has a less adverse effect on the pour point, when blended with a conventional oil, than bright stocks dewaxed by other processes.  Specification 819,121 is referred to.

Title: Improvements in or relating to release mechanism for coin controlled turnstiles
IPC: G07F17/14
Filed: 1936-02-15
Abstract: 468,800. Coin - freed turnstiles. DOLMAN, H. J. Feb. 15, 1936, No. 4630. [Class 27] The vertical rotary pillar 1 of a coin-freed turnstile provided with arms 2 has fixed to it a cam 8 which drives anticlockwise a member 10 pivoted on a short spindle 5 and biassed by a spring 11 so that a roller 12 thereon is kept in contact with the cam. Anticlockwise rotation alone of the arms 2 and pillar 1 is permitted, rotation in the reverse direction being prevented by a pawl and ratchet wheel. Normally, the turnstile is locked by the engagement in a notch 14 on the member of the nose 15 of a locking member 16 freely rotatable on the pillar 1 and held in locking position by a spring 17. When a coin is inserted, a solenoid 22 is momentarily energized and an armature rod 21 moves to the right to release the locking catch 16 which is connected by a link 19 to a lug 20 on the rod 21. The turnstile arms 2 can now be moved in the direction of the arrow, the cam 8 driving the member 10 by one of the slanting surfaces 28 thereon engaging the roller 12. The line of action of the thrust between the surface 28 and the roller 12 passes close to the pivot 5, so that the pressure between the nose 15 and notch 14 is small during the initial rotation and the locking catch is not thereby prevented from being released, should a pressure be exerted on the arms 2 before the insertion of .a. coin. When the armature rod moves to the right, it is held in that position by the arm 29 of a lever 23 controlled by a spring 25 engaging an abutment 30 on the rod. An abutment 27 on the member 10 engages the lever 23 and rotates this to release the rod 21 so that the locking catch returns to its normal position ready to engage the notch 14 when the turnstile has completed a quarter-turn. At the end of this quarter-turn, the cam 8 engages a second roller 26 on the member 10 to return this member to its initial position. Coin action, multiple - coin.-When the armature rod 21 moves to the right, a finger 35 thereon closes contacts 33, 34 to energize an electromagnet which moves an obturator into the coin track to detain further coins that may have been inserted. The contacts are held closed, when the rod 21 is released, by one arm 41 of a bell-crank lever 36, 41 controlled by a spring 38 and displaceable by projections 40 on the cam 8.
