Patent GB-1010912-A (GB)
Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B17/00
Filed: 1961-03-29
Abstract: In the manufacture of a ribbon of glass of predetermined thickness, glass 22 is delivered at a controlled rate to a bath 12 of molten metal and advanced under thermal conditions to form a layer 28 of molten glass which is maintained molten until there is developed on <FORM:1010912/C1/1> surface tension, the buoyant body 30 being advanced in ribbon form and gradually cooled to a transitional plastic state 34 in which the glass is attenuated by a tractive force, dissipated in the plastic glass, to give a predetermined decrease in thickness, the attenuated ribbon 35 then being cooled to permit removal unharmed from the bath 12.  Molten glass 11 from a furnace is fed under a regulating tweel 2 over the lip 4 of a spout 3 between side jambs 5 and is either regulated in thickness by a gate 10, Fig. 3, or by passage between casting rolls 6, 7, Fig. 2, driven by toothed wheels 9, the molten ribbon 22 of glass passing on to the bath 12 of molten tin.  The bath 12 is in a tank 13, 14, 15 enclosed by a roof 17, the end walls 18, 19 (not shown) of which are arranged to leave an inlet 21 and outlet 23 for the glass.  The buoyant body 30 of glass is formed in a first zone between the wall 18 and a refractory partition 29 provided with heaters 26 in the roof 17 and heaters 27 in the bath 12 to maintain a temperature of about 1000 DEG C. for soda-lime glass to melt the ribbon 22 and maintain the layer 28 in molten form.  In a second zone between partitions the surface 16 of the bath 12 a buoyant body 30 of stable thickness by permitting the layer 28 to flow laterally unhindered to the limit of its free flow under the influence of gravity and <FORM:1010912/C1/2> 29, 31, heaters 32 (not shown) in the roof 17 and regulators 33 (not shown) in the bath 12 maintain a temperature gradient from about 850 DEG  C. to 700 DEG  C. to gradually cool the glass 34 through a plastic state during which time the tractive force from rollers 37, 38 outside the tank attenuates the ribbon to the required thickness.  In the third zone between partition 31 and end wall 19, the ribbon 35 is stabilized and cooled to about 650 DEG  C. by regulators 36 (not shown) immersed in the bath 12.  The bath 12 of tin is prevented from oxidation by maintenance of a non-oxidizing gas fed to the enclosure through pipes 20a, the end of the tank being covered by a roof 24 and end walls 25.

Title: Improvements in or relating to methods of and means for raising sunken ships
IPC: B63C7/16
Filed: 1930-04-11
Abstract: 358,965. Raising sunken ships. ALBERT, H., 18, Winarskystrasse, Vienna. April 11, 1930, No. 11612. Convention date, April 15, 1929. Void [Published under Sect. 91 of the Acts]. [Class 68 (ii).] A float is released from a sunken ship, carrying with it an auxiliary line by means of which a lifting - device and chain are attached to the ship. As shown in Fig. 4, a. float f closes the aperture of a cuplike fitting b in the hull of a ship, and is released therefrom automatically by a time switch or other device, e.g. a cartridge e containing acids which, when water enters, destroy a zinc wire. The float rising to the surface, affords, with a signal light, a means for indicating the position of the ship. The crew of a rescue ship should then remove from the float the ends g, h of an auxiliary line i, which passes round a roller c. and fix one end to a coupling-device, Fig. 5, on a lifting-chain l. The other end of the line i is then drawn inboard until the coupling- device is drawn into the mouth of fitting b. As it enters, a pin or bar st is removed from the coupling-device by contact with the mouth of the fitting b ; springs on the pivot pin o then cause the jaws p, q to fly out and engage the under. side of the throat of the fitting. The sunken ship may then be raised by the lifting-chain l. In a modification, a single line i is used, and serves as a guide line down which a coupling-device, Fig. 8, is run down to the sunken ship. The frame of the device is formed with a cone-like body k, which facilitates the entry of the coupling into the body of the ship. The coupling moves on rollers y running on the auxiliary line i, moving either by gravity or by a propeller action.

Title: Improvements in or relating to polyformals as synthetic lubricants
IPC: C07C41/60
Filed: 1954-04-26
Abstract: The invention comprises polyformals of the general formula AO(CH2O)nB, wherein A and B represent the hydrocarbon radicals of branched chain alcohols and n is an integer of at least two, the polyformals containing 20-130 carbon atoms in the molecule.  They are prepared by reacting formaldehyde with a branched chain alcohol or with the monoformal of a single or two different branched chain alcohols at a temperature between 60 DEG  and 250 DEG  C. in the presence of an acid catalyst, the alcohol or monoformal and the proportions of this compound and the formaldehyde being so chosen that the resulting polyformal has between 20 and 130 carbon atoms to the molecule.  The reaction using an alcohol is generally effected at a temperature of 60-200 DEG  C.; temperatures of 100-250 DEG  C. are used in the case of the monoformals.  The branched chain alcohols are preferably oxo alcohols and may contain up to 60 carbon atoms.  In general, 1.65 to 0.10 mols. of alcohol are used per mol. of formaldehyde.  The products may be used as plasticisers, solubilizers, heat transfer agents, grease-bases, insecticides, weed-killers, detergents, rust preventatives and, especially, as or in lubricants (see Group III).  In examples: (1) C13 oxo alcohol is heated in a bomb at 100 DEG  C. with formaldehyde in a molar ratio of 1.0 or 0.5: 1, using p-toluene sulphonic acid or NaHSO4 as catalyst and the products washed with alkali and dried; their lubricating characteristics are compared with those of the monoformal of the same alcohol prepared under the same reaction conditions; (2) a polyformal containing an average of 5 formaldehyde units is prepared similarly by reacting 1 mol. of the monoformal of the C13 oxo alcohol with 8 mols. of formaldehyde at 175 DEG  C.; other experiments are described in which 4 mols. of formaldehyde or trioxane are used.  Numerous other acid catalysts are mentioned including ion-exchange resins. Specification 603,872 is referred to.ALSO:Lubricating compositions comprise polyformals having the general formula AH(CH2O)nB, wherein A and B represent the hydrocarbon residues of branched-chain alcohols, which may be the same or different and n is an integer of at least 2, the compounds containing 20 to 130 carbon atoms in the molecule.  The polyformals may be used alone or in conjunction with mineral oils, or synthetic lubricants such as dibasic acid ester, complex esters, silicone oils or polymerized hydrocarbons.  They are compatible with the usual additives.  Examples compare the lubricating properties of various polyformals of a C13 oxo alcohol with those of the monoformal.  The preparation of the polyformal is given (see Group IV(b)).  Specification 603,872 [Group IV(b)] is referred to.

A pump 20 discharges liquid, supplied by reservoir 25, to combined inlet and outlet valves 22 on each accumulator. In the arrangement shown with the left and right hand accumulators fully charged and discharged respectively, liquid is supplied to the pressure chamber 12 of the right hand accumulator thereby raising member 10 and sucking liquid from the reservoir 25 into chamber 13. At the top of its stroke member 10 actuates plunger 35 to close supply valve 36. Meanwhile the chambers 12, 13 of the other accumulator discharge through valve 22 to a motor until member 10 reaches the bottom of its stroke and depresses a plunger 40 thereby operating a motor 39 to reverse both valves 22. Left hand accumulator is then charged and the right hand one discharges to the motor. The motor comprises a rotor 44 having buttress teeth 45 supplied tangentially with pressure liquid through a nozzle 50 in a piston 48 which is subjected to a regulable pressure on its upper face. The casing is connected through pipe 52 with a reservoir whereby it is always full of liquid.
