Patent GB-392194-A (GB)
Title: Improvements in or relating to titanium compounds
IPC: C01G23/08
Filed: 1931-11-09
Abstract: Titanium oxide is obtained by hydrolysing a titanium solution which contains a high concentration of titanium, for example, 150 grms TiO2 or more per litre, and an amount of acid corresponding to the normal salts of bases other than titanium and, in addition, an amount equal to or up to 50 per cent less than that corresponding to the normal titanium salt, the hydrolysis being initiated or maintained by the addition of acid-binding substances in quantities which do not cause any considerable decrease in the total acidity of the solution. Quantities used vary from 0,1 per cent of the weight of the solution to an upper limit of about 10 per cent of the amount equivalent to the total acid combined with the titanium.  As acid-binding substances, alkali silicates, and oxides, hydroxides or carbonates of zinc, magnesium, alkali metals or ammonia are specified.  Mixed pigments may be obtained by suspending an insoluble sulphate in the solution during the hydrolysis.  In an example, ilmenite is decomposed with sulphuric acid, and the acid-poor, titanium-concentrated solution is treated with a reducing agent such as metallic iron and freed from slimes.  Iron sulphate is optionally crystallized from the solution which is then treated with hydrogen sulphide or an acid-soluble sulphide. After filtration, the solution is hydrolysed as above, if desired, under increased pressure.  The washed precipitate is calcined at 800-1,000 DEG  C., or at lower temperatures.  Phosphoric acid, phosphates or other phosphorus compounds may be added immediately prior to calcination of the precipitate or earlier in the process.  Neutralizing agents, such as the oxides, hydroxides, chlorides or carbonates of the alkaline earth metals, or the carbonates or hydroxides of the alkali metals or ammonia, or magnesium oxide, hydroxide or carbonate, and sintering agents, for example, sulphates, silicates, fluorides, boric acid or borates may if desired be added to the precipitate prior to calcination. The sequence of the operations of reducing and purifying the titaniferous solution may be varied.  Specifications 102,059, 110,153, 110,535, [all in Class 1 (iii), Oxides &c., Metallic], and 387,720 are referred to.

Title: Improved bearings for oil film lubrication
IPC: F16C17/06
Filed: 1931-11-13
Abstract: 381,377. Tilting pad bearings. BOLTON, E., 514, Wilbraham Road, Chorlton-cum-Hardy, Manchester. Nov. 13, 1931, No. 31416. [Class 12 (i).] A bearing pad a, or an adaptor to which a bearing pad is fixed, is integrally connected to a surrounding frame b by yielding strips c. As shown in Figs. 1 and 2, for a unidirectionally rotating shaft, the pad a and frame b are made from a single piece of metal the bearing face of the pad projecting slightly above the upper face of the frame. The yielding strips c are formed by milling through the side edges of the frame b at the places where the pad is joined to the frame and this milling operation is performed after the pad has been machined in place. The fulcrum d for the pad a is formed by a corner or edge of a seating e on which the frame b rests. For a shaft which is to rotate in both directions the frame b, Fig. 4, is separated from the seating e by distance washers and a separate fulcrum d is inserted between the pad a and seating e. Alternatively recesses may be made around the fulcrum whether the latter is integral with the pad or with the seating. Fig. 6 shows a bearing pad a fixed to an adaptor carried by a frame b, the pivot d of which is level with the lower face of the frame b being formed by recessing the upper face of the seating e. The bearing pad a may be more rigidly secured to the frame by connecting it by three or more yielding strips as shown in Fig. 8. Four parts such as shown in Fig. 8 when assembled round the shaft form a complete journal bearing. The lower face of the pad and frame may be curved so that the bearing may be assembled in a bearing bush.

Filed: 1955-11-03
Abstract: 800,340. Oscillating electric motors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 3. 1955 [Nov. 6, 1954], No. 31474/55. Class 35 [Also in Group XVIII] The maintaining circuit for the oscillating balance of a timepiece or motor contains a pickup coil and a driving coil and comprises means for decreasing the amplitude of the driving impulses as the amplitude of oscillation of the balance increases so that the amplitude of said oscillation tends to be restored to a desired value. In an electric timepiece the maintaining circuit comprises a pick-up coil 8, Fig. 1, connected between the base and emitter of a transistor 9, a battery 24 and a driving coil 10 connected between the collector and base of the transistor 9. The pick-up coil co-operates with a disc-shaped permanent magnet 5, Figs. 1 and 2, and the driving coil 10 co-operates with a permanent magnet 6, both magnets 5, 6 being carried by the balance staff 2. The battery 24 is of low voltage and/or the driving coil 10 of a high resistance so that the instantaneous value of the collector current is limited by a corresponding decrease in the collector voltage. A voltage is induced in the coil 10 by the magnet 6 so that with increasing amplitude of balance staff oscillation the amplitude of the driving impulses decreases. The same result may be obtained by applying the voltage produced across the coil 10, or a further coil, with an appropriate phase, to the amplifier input. Specification 800,341 is referred to. Reference has been directed by the Comptroller to Specification 746,465.

Filed: 1961-09-01
Abstract: 953,571. Bearings. S. A. SIEURIN. Sept. 1, 1961 [Sept. 7, 1960], No. 31489/61. Heading F2A. [Also in Division G5] A magnetic bearing has at least two rotatable members, with engageable convex-shaped surfaces, which are attracted to each other by magnetic forces. In an embodiment a magnet 6 is housed in a housing 1, having a closed end 2 and an end wall 4 with an aperture 5 through which passes a shaft &c. 9. The magnet 6 attracts a hemispherical member 7 of magnetic material, alternatively the member 7 is joined to the magnet 6. A ball 8, connected to the shaft 9, is attracted by the member 7, and thus a load supported by the shaft 9 is rotatably carried by the bearing. The shaft 9 is centred within the aperture 5 of the end wall 4 due to the convex shapes of the contacting members and could be supported mechanically by the end wall 4 should the magnetic force be insufficient to carry the load. The hemispherical member 7 may be replaced by a spherical member and a hook 3 may be provided to facilitate suspension of the bearing. In another embodiment a horizontal shaft 14, Fig. 4, having a ball 8 at each end thereof, is suspended magnetically. Each ball 8 is attracted to a ball 10 within a housing 1containing a magnet 6.

Title: Improvements in imitation fuel
IPC: F24C3/00
Filed: 1932-11-09
Abstract: 410,123. Imitation fuel ; embossing non - metallic substances. PREMIER ELECTRIC HEATERS, Ltd., and NEWTON, A. E., Premier Works, Keeley Street, Birming- ham. Nov. 9, 1932, Nos. 31579/32 and 6611/33. [Class 126.] Imitation fuel is manufactured from fabric such as calico, voile, or muslin by applying to it a stiffening fluid, subsequently pressing or folding it to the shape of fuel, and then setting it so that it retains this shape ; alternatively, the fabric is moistened, folded or pressed to the shape of fuel whilst moist, and set in this shape by heating. In one method the fabric is crushed into a ball, immersed in an aqueous solution of ammonium chloride, and dried. The fabric, thus stiffened and fireproofed, is then cut into pieces which are shaped by folding or pressing, overlapping parts 10 being retained by sewing, riveting, &c. The resulting fuel bodies are then dipped in a silica solution, prepared for example as described in Specification 290,717, [Class 1 (i)]. After drying, a second application of the solution is made, and small flakes of mica, glass, &c. are applied. Further applications of the solution follow, the body being also coloured black in parts, whilst ash-simulating material may be applied. In another method, the fabric is moistened with an adhesive, such as glue, then placed on a die or former, which may be made of synthetic resin, steel, or other non-adhering material, and finally dried by heat and removed. In a third method, the material is immersed in an aqueous suspension of magnesium borate, wrung out, and placed whilst wet in a hollow liner 16, conveniently formed by electrodeposition or beaten from a metal sheet. The liner is then placed in a heated die 20 of castiron and an upper die 21, preferably of lead, is applied. When dry, the fabric is removed, painted, and treated one or more times with an aqueous solution of sodium silicate, which is dried by heat. Alternatively, the silica solution previously referred to may be used. The fuel pieces may comprise a single lump or a unit representing a complete fire. They may also be made to resemble logs.

Title: Improvements in vehicle couplings and draw gear
IPC: B61G3/16
Filed: 1957-10-10
Abstract: 851,457. <SP>Railway</SP> vehicle couplings and draw gear. HILGER, O., and BUSCH, W., [trading as BERGISCHE-STAHL-INDUSTRIE]. Oct. 10, 1957 [Oct. 11, 1956], No. 31737/57. Class 103(5). A draw and buffing gear comprises an automatic central coupling head 23 in combination with a draw hook 19 and centering arrangement, the hook 19 and coupling 23 together being pivotally connected to the draw bar 6 by the vertical pin 16, and the coupling 23 alone being pivotally connected by means of a forked end 25 to a horizontal pin 22. During change over of coupling arrangements on existing rolling stock, the draw gear may be fitted to trucks already having buffers, the buffing forces then being shared. When the existing buffers are later removed their springs may be used to replace the weak temporary spring in the draw gear. A pre-compressed spring 13 is arranged between a fixed plate 2, and a plate 12 held from moving forwards by abutments 11, so that the draw and buffing forces are taken by the springs 10 and 13 respectively via the draw bar 6 passing through holes in the plates 2 and 12. If however the abutments 11 are not provided, then the pre-compression of the spring 13 is accepted by the spring 10. The spring 13 however may be replaced by a stronger compression spring or springs if the coupling is to be used as a central buffer, the abutment 3 and spring 10 being removed so that the tractive force is taken up by the compression spring. Abutments 32 limit the buffing movement. The pin 16 is received in an eye 15 at an end of the bar 6, and also by forks 20 of the hook 19 having flat ends 35 engaging the plate 12. Projections 17 provided on the plate 12 are shaped to whatever form the eye 15 is given, so that buffing forces are transmitted from the eye through the projections 17 to the plate 12, thus relieving the draw bar of load. When the coupling 23 is pivoted downwardly about the pin 22 the hook 19 may be used to couple with trucks not provided with central buffing gear, but in use the coupling 23 is held substantially horizontal by a pin 28 which passes through the jaw of the hook 19 and is connected by bearers 30 and springs 29 to the coupling. The pin 22 is a loose fit in the eye 21 of the hook 19 so that the forked end 25 of the coupling 23 strikes an abutment 24 on the draw hook shaft when buffing occurs, thus relieving pin 22 of load. The draw bar, hook, and lugs of the plate 12 are so constructed that the compression spring 13 has a centering effect, and a coupling 31 is provided on the coupling head 23 for air lines and so on.
