Title: Improvements in and relating to disc brakes
Inventor: RODWAY JOHN
IPC: F16D55/2255
Filed: 1963-01-25
Abstract: 1,066,842. Disc brakes. AUTOMOTIVE  PRODUCTS CO. Ltd. Jan. 13, 1964 [Jan. 25,  1963], No. 3320/63. Heading F2E. A disc brake comprises a fixed support 1, a movable member 2 arranged on the fixed support so as to be movable in a chordal plane of the brake disc 3, brake pads 11, 12 on opposite sides of the brake disc and brakeactuating means 14, 29 carried by the member 2 and operable to move the brake pad 11 into contact with one side of the disc, the reaction set up resulting in movement of the member 2 to bring the brake pad 12 into contact with the other side of the disc, and means operable as a result of displacement of the pad 11 due to the drag force created by its contact with the rotating disc 3 to effect movement of the pad towards the disc to produce a wedging effect between the pad and the disc. The said means, as shown in Fig. 1, comprises an arm 23 pivoted at 24 to the movable member 2 to be able to swing in a plane normal to the plane of rotation of the brake disc 3 and a backing plate 21 behind the brake pad 11 with one end formed to provide a surface 22 which is inclined to the plane of rotation of the disc 3. Upon displacement of the brake pad 11 by the drag force on it from the disc 3, rotating in the direction " A," the arm 23 tends to swing in a direction towards the brake disc and apply a load to the leading end of the brake pad 11, this load combining with the thrust from the actuating means 14, 29 to produce the wedging effect referred to. In a modification (Fig. 3, not shown), the backing plate 21 has an inclined surface at each end. On one surface, 33, the brake-actuating means, which is inclined to the plane of rotation of the disc, acts; on the other surface, 22, a ball or roller 34 presses, being loaded by a  spring 36 against one side of a slot 35, from  which position it is moved against the spring  during operation of the brake. In another modification the ball or roller may be in a slot formed in the backing plate 11 and co-operate with an inclined surface on the movable member 2. In both of the two last-mentioned modifications, and as further modifications, a roller 37, Fig. 8 (not shown), may be used with two opposite flats 38 facing the edges of the slot 35 and the compression spring 39 housed in the roller.

Title: Process and apparatus for the manufacture of flat glass
IPC: C03B15/08
Filed: 1973-01-23
Abstract: 1402972 Drawing sheet glass GLAVERBELMECANIVER 23 Jan 1973 [24 Jan 1972] 3422/73 Heading C1M In a process for producing flat glass by vertical drawing a draw bar is provided immersed in the molten glass which has been modified to accommodate a pool of molten material which is denser than and not wettable by, the molten glass. The molten material may be thermally conditioned by heat exchange with at least one body such as cooling tubes 42, 43, 44, 45 (Fig. 3) carrying a cooling fluid, e.g. water. Alternatively thermal conditioning may be achieved by circulating the molten material ; as shown in Fig. 6 the molten material passes through perforations in a tube 59 and is returned to the pool through perforations in the tubes 58, 60 after passing through a suction pump 63, purifying device 64 and heat exchanger 65, or (as illustrated in Fig. 8) by electromagnetic pumps 80, 81. As a third alternative thermal conditioning may be achieved by selecting the shape of the draw bar as shown in Fig. 2 so that the trough 18 in the draw bar 16 for containing molten material has in plan enlarged end portions 20. One or more of these thermal conditioning techniques may be combined, so that, e.g. in Fig. 8 in addition to the provision of circulating means the two troughs each have enlarged ends. Also in this embodiment the draw bar is described as being made of tungsten. Suitable molten materials disclosed are tin and lead. The invention is applicable to both Pittsburg and Libbey-Owens methods.

Title: Fluidised bed process for the production of titanium dioxide
Inventor: EVANS ARTHUR WALLACE
IPC: C01G23/07
Filed: 1962-01-30
Abstract: Titanium dioxide is recovered from above a hot fluidized bed in which, in the presence of a source of K, Rb or Cs, an oxygenating gas reacts with titanium tetrahalide other than TiF4.  The K, Rb or Cs source may be added batchwise to the bed, giving a concentration by weight (estimated as oxide) with respect to the weight of the bed of 0.1-5%; or continuously, with concentration with respect to TiO2 produced of 2%; if 0.1-1% of a source of Na, Li or Group IIa or IIb elements be added to the bed, only 0.01-0.05% K, Rb or Cs is required.  The sources of the elements may be salts, hydroxides or the elemental metals, e.g. as vapour. The source may be introduced, e.g. with a reactant, as a solid or liquid or a solution; the bed particles may be slurried with source solution and dried before use; or the source may itself form all or part of the bed particles, e.g. as potassium aluminium silicate.  The titanium tetrahalide, e.g. TiCl4, may be introduced as a vapour; the oxygenating gas may be O2 with or without inert gas, e.g. as air; other gases, e.g. N2, may also be introduced.  The bed temperature is 800 DEG -1200 DEG  C. Additional heat may or may not be supplied, e.g. electrical heating, preheating one or more input gases, or burning a fuel, e.g. CO, in the bed with additional oxygenating gas.  Bed particles, e.g. SiO2, ZrSiO4, Al2,O3 or TiO2, have size 50-2,000 m .  Minor proportions of rutilizing agents, e.g. aluminium halide, zirconium tetrahalide, water vapour, or other TiO2 crystal-modifying agents, e.g. halides of Si, Sb and P, may be added.  The TiO2 may be recovered from the effluent gas by use of a cyclone to remove larger particles and filtration to recover pigmentary TiO2. The gaseous halogen product may be separated by liquefaction and used to produce more titanium tetrahalide.  In examples the pigmentary TiO2 recovered had rutile content of about 98%; after wet milling the bed material up to about 13% of the trahalide admitted was retained thereon as TiO2; in a contrasting run in which the source was omitted, 40% tetrahalide was retained.  Specifications 761,770 and 986,660 are referred to.

Title: Position and rate sensitive gyro
IPC: G01C19/42
Filed: 1955-02-08
Abstract: 767,069. Controlling aircraft. SUMMERS, T. O. Feb. 8, 1955 [Feb. 24, 1954; Feb. 24, 1954], No. 3742/55. Class 4. [Also in Group XX] Gyroscopic apparatus 43 to detect change and rate of change of an aircraft 191 from a given flight path or optimum attitude generates a signal to energise a motor 192 which operates a control surface or surfaces 194 in a sense to restore the aircraft to its correct path or attitude. The apparatus comprises a base member 30 having spaced legs 36 extending therefrom to support an end plate 38 having projections 39, 40 to support an enclosing cover 43. A gimbal 45, mounted for rotation in the plates 30, 38 by bearings 57, 51, carries a motor and the shaft of the gimbal passing through plate 38 carries an arm 98 having a wiper contact 100 which moves over a winding (not shown) to pick off a voltage fed to the motor 192. The shaft also carries three slip rings 114, one to carry the said voltage and the other two to carry current to the motor mounted in the gimbal. On the side opposite to the gimbal mounting the plate 30 carries four projections 119 to support a frame member 120 which carries an enclosing casing 135, magnetic shielding plates 124 and a member 126. Magnets 138 and 140 and pole pieces 128 and 129 are secured to the member 126. A circular opening is formed in member 126 and brackets 152, 153 at the ends of the opening carry screws which support and tension a wire support 146 fast with the armature core 142. This core, at its ends, carries bearings for a resin-impregnated self-supporting armature winding 155 which has a commutator 160 engaged by brushes and leads (not shown) whereby the motor may be selectively energized. The armature carries a pinion 173 forming one element of a gear train wherein the last gear 181 is secured to a torsion shaft 185 attached at its other end to one shaft of the gimbal 45. By this mechanism, the total displacement of the gimbal relative to the aircraft upon movement of the aircraft has two components, one representing the twist in rod 185 resulting from torque of the gimbal which is proportional to angular velocity and the other representing displacement of the damper motor resulting from gimbal velocity, which displacement is proportional to the displacement of the aircraft. A further embodiment is described in which three pick-offs are utilized, one for signalling pure rate, one for signalling position and another for signalling the algebraic sum of position and rate.

Abstract: 665,681. Carbonizing-apparatus. PITTSBURGH CONSOLIDATION COAL CO. Feb. 14, 1949 [Feb. 28, 1948], No. 3958/49. Class 55 (i). Finely divided bituminous coal is fed from a hopper 14 into a horizontal rotary drum 10 together with a separate stream of residues from a previous distillation which have been heated in a vessel 60 by partial combustion with air &c. to such a temperature that the feed material is distilled solely by the sensible heat supplied by the residues. Lifters 22, 24 continuously raise the carbonized material from the bed 20 and discharge it into a conduit 27 through which also the evolved gases escape to a dust separator 30 and scrubber 36. Solid residues are discharged partly to storage and the rest after screening the oversize particles to a hopper 56 feeding the heater 60 in the lower half of which a fluidized bed of residues is maintained by an oxygen-containing gas introduced through a tube 70. Cylinders 72, 76 remove fines from the gases which have a low thermal value capable of modification by using steam in conjunction with air as the fluidizing current. The coal charge may be preheated and the temperature difference between the residue and the distillation temperature may be as low as 50‹ F. The latter temperature may be controlled by adjusting the proportions of coal and residues by means of the screw feeders 16, 18 and the temperature of the residues. A ratio of less than 1 of high volatile Pittsburgh seam coal to 3 of its residue was found to be necessary to avoid agglomeration ; the coal in sizes of less than “ inch was distilled in 15-20 minutes at 900‹ F. the heater temperature being 1200‹ F.
