Filed: 1921-07-28
Abstract: 184,053. Jackson, W. J. Mellersh-, (Libbey Owens Sheet Glass Co.). July 28, 1921. Drawing.-Relates to sheet-drawing apparatus of the type described in Specification 114,977 in which marring of the surface of the sheet is prevented by adjusting the temperature between the drawing point and the bending-roll 5. The invention consists in reheating the sheet 2, for example by gas jets 12, at the point X where it leaves the roll so that the drawing tension overcomes the tendency for corrugations to form in the sheet due to bending the cooled sheet. Air may be circulated through the roll 5 to prevent it from becoming overheated.
Patent GB-754889-A (GB)
Title: Improvements in the production of titanium monoxide
IPC: C01G23/04
Filed: 1954-07-12
Abstract: Titanium monoxide is formed by reducing titanium dioxide with elemental carbon in two stages.  In the first stage an intimate mixture of the dioxide with at least 1/2 but not more than 1 mol of elemental carbon per mol of dioxide is heated to 1100 DEG  to 1200 DEG C. whilst removing evolved carbon monoxide and maintaining the temperature until the carbon monoxide evolution ceases thereby producing titanium sesquioxide.  In the second stage the sesquioxide is admixed with an equi-molecular quantity of elemental carbon and heated to 1500 DEG  to 1800 DEG C. until carbon monoxide evolution has ceased thereby producing the monoxide.  If desired the total amount of required carbon can be incorporated in the initial dioxide/carbon mix in which case one mol of carbon per mol of dioxide must be present.  Suitable forms of carbon are lamp black or petroleum coke both preferably purified by calcination in a neutral atmosphere to a temperature of at least 1370 DEG C.  The reaction is preferably effected in a graphite crucible lined at least on the bottom with molybdenum sheet into which the dioxide/carbon mixture is preferably tamped, blow holes being provided to allow gas evolution. Alternatively the mixture may be briquetted.  The furnace should be swept with a current inert gas or preferably, operated under high vacuum that is below 100 microns of mercury.  When operating under vacuum the end of both the first and second stages is indicated by the restoration of the vacuum to its original value after a rise due to gas evolution. The titanium dioxide employed is preferably pigment grade but ilmenite or rutile may be employed.  Metallic iron formed when ilmenite is employed may be removed by magnetic separation from the final monoxide-containing reaction products.

Filed: 1929-07-02
Abstract: 314,874. Aktiebolaget Spontan. July 3, 1928, [Convention date]. Controlling different functions by same lever; stop gear operated by driver releasing a lever.- Relates to motor vehicles of the kind in which the brakes are applied by spring action and the engine drives the wheels through variable gearing such as that described in Specifications 281,983 and 291,071, [both in Class 80 (ii), Gearing, Variablespeed &c.], and comprising locking devices cooperating with the driven shaft and with a stationary member, positive and negative turning moments being alternatively transmitted to the locking devices as, e.g., by masses having planetary movements. According to the present invention a single operating member is provided which simultaneously releases the spring-applied brakes and disengages the locking device acting on the stationary member thus disengaging the variable gear from the road wheels and leaving the car free to be moved. A hand- or foot-operated shaft 44 carries an eccentric 45 having a strap connected by a slotted link 47 to a pin 48 on an arm 39 controlling the brake-operating shaft 41. The shaft 44 is screwed at 51 and engages in a fixed nut 52 so that as the shaft is rotated it moves axially and a collar 50 thereon bears against and rocks a lever 53 pivoted at 54, this lever being connected to toggle links 30 which release a brake acting on the locking devices of the variable gear (not shown). Thus when the shaft 44 is rotated by the driver the service brake-shaft 41 is rotated to release the brakes and the toggles 30 are actuated to release the locking devices. The brakes are normally applied by a spring 33 acting against an adjustable abutment 36 and the arm 39, the arm having a roller 40 bearing against a cam 42 on an arm fixed to the brake-shaft 41. The brakes are released when required by means of a pedal 43 on the shaft 41.
