SO 3 . In the illustrated embodiment wet acid is charged to reactor 1 where its fluorine content is precipitated as Na 2 SiF 6  by addition of, e.g., Na 2 SO 4 . The liquor is mixed in tank 2 with the desired amount of H 2 SO 4  and also with phosphoric acid from wash column 4, this mixed acid is then cooled &c. and passed in countercurrent flow to extractant (tributyl phosphate) in column 3. The extract leaving 3 is heated in exchanger 10 and washed in column 4 with aq. phosphoric acid at 40-70‹ C. The washed extract then passes to stripping column 5, after heating to 70-100‹ C., where it is countercurrently contacted with water to remove P 2 O 5  values therefrom. The phosphoric acid solution is optionally passed through a charcoal bed 6 to decolorize, and is finally concentrated in evaporator 7.

Abstract: 1297076 Cahtode-ray tube circuits LICENTIA PATENT-VERWALTUNGS-GmbH 31 March 1970 [2 April 1969] 15222/70 Heading H4T In a cathode-ray tube character display system in which all the character forming vectors are traced in equal time intervals irrespective of the lengths of such vectors constant brightness of the latter is achieved by controlling the beam intensity by means of a voltage derived from the X and Y deflection coils. As shown, transformers TX, TY connected to the horizontal and vertical deflection coils LX, LY, respectively, feed rectifiers DIX, D2X and D1Y, D2Y which provide voltages UHx, UHy proportional to the rate of variation of the deflection currents and these voltages are then combined via resistors R1, R2 to produce across resistor R3 a voltage UH which (after amplification if necessary) is fed to the beam intensity control electrode. Fig. 2, shows the manner in which the voltage UH varies as a (unit) vector moves counterclockwise from the X-axis to the Y-axis. Thus as the vector roates between # = 0 and # = 27¢ degrees the voltage UH varies according to the broken curve portion 4, between # = 27¢ and # = 72¢ degrees it varies according to the chain curve 3 and between # = 72¢ and # = 90 degrees according to the broken curve portion 5. With this arrangement the locus of the vector brightness deviates from the ideal locus, arc 1, by a maximum of about 11%. If, however, a maximum deviation of about 30% can be tolerated, the arrangement of Fig. 1 may be modified as shown in Fig. 1a to produce the vector brightness locus 4,2,2,5 (Fig. 2).

The olefinic resin, which is preferably a C 2 -C 4  α-olefin polymer or copolymer having a melt index of from 0À01 to 5, may be blended with up to 50 wt. per cent of a resin having poor compatibility with the olefin polymer or copolymer, e.g. a styrene polymer, polyamide, polyacetal, polyacrylate, vinyl chloride, vinyl acetate, phenoxy or high molecular weight elastomer resin and the blend may also contain up to 75% (based on the weight of the composition) of a powdered inorganic filler material, e.g. talc, mica, zeolite, asbestos, lithopone, clay, kaolin, diatomaceous earth, silica, alumina, CaCO 3 , MgCO 3 , CaSO 4 , BaSO 4 , ZnS, TiO 2  or ZnO. To further improve the weight and surface characteristics of the sheets they may be uni- or bi-axially after-stretched at a temperature which is below the melting temperature of the resin and may be either below or above the temperature of the surface layers of the sheet during the primary stretching process. In examples olefinic resins comprising low pressure polyethylene (Examples 1 and 7); high density polyethylene (6); and low pressure polyethylene blended with inorganic filler materials and polystyrene and an ethylene/vinylacetate copolymer (2); high pressure polyethylene, styrene/vinyl acetate copolymer and a phenoxy resin (3); ethylene/vinyl acetate copolymer, polystyrene, and a styrene/butadiene copolymer (4); and styrene/vinyl acetate copolymer, polybutadiene, and polystyrene (5) are kneaded with a roller at 150-160‹ C., converted into sheets by hot pressing or calendering, cooled to 80‹ C. and passed between rollers maintained at 100-124‹ C. and stretched biaxially to 2À5 x their original length and width.

The arm 2 may be pivotally connected to one end of a transverse bracket 11 secured to the lever 6, the other end of the bracket having a hole 12 which can be aligned with a hole 5 in the arm 2 so that a pin can be passed through the holes to lock the arm 2 at right angles to the lever 6. One end of the lever 6 has a member 8 bent to engage in use over the wheel rim, the member carrying a roller 7 for engaging a tyre bead. In use to fit or remove a tyre, the lever 6 is first rotated around the assembly with the arm 2 fixed at right angles thereto and the rollers 7 and 1 in engagement with a tyre bead and a wheel rim flange 10 respectively, and then when about 75% of the tyre periphery is either fitted or removed from the rim, the pin is removed from the holes 5, 12 whereafter continued rotation of the lever 6 causes the roller 7 to move towards the roller 1 to the position shown in which the tyre lever can easily be removed.

Abstract: 1332643 Coin-freed time switch ALBERICE ELECTRICAL Ltd 20 Nov 1970 [2 Jan 1970] 176/70 Heading G4V A coin or token freed time switch mechanism comprises a timer and switch unit 14 (Fig. 1), and a casing 10 housing a removable coin or token receptacle 56, there being means 58 for preventing unauthorized access to coins or tokens in the receptacle 56 when removed from the housing. The timer and switch unit 14 is secured to the housing 10 by an allen screw 60, and is supported by a base-plate 64. The receptacle 56 is removably locked to the housing 10 by a lock 17, and a coin access opening is normally closed by a cover-plate 57 and lock 58. Operation.-As described with regard to a prepayment meter for a television set, coin insertion followed by turning of a handle 52 produces rotation of a gear wheel 54. The rotation is transmitted to a shaft 44 and gear wheel 24 through a gear 30, crown gear 32, and planet gears 34 that are supported by the shaft 44. The resulting movement of an abutment 24a of gear 24 operates a lever system (not further disclosed) to switch on a microswitch 22 and so condition the television for use. Successive coin insertions rotate the gear 24 through equal amounts. Use of the television switches on a timer motor 18 to rotate gears 40, 38. The rotation is transmitted to the shaft 44 through a crown gear 36 and the planet gears 34, resulting in reverse rotation of gear 24. After a period of use, the abutment 24a and lever system switch the microscwitch 22 off, to disable the television. The number of coins inserted in the receptacle is displayed on a counter, and gear 24 carries a "time-remaining" indicator. Tampering.-The timer and switch unit 14 is protected against tampering while the coin receptacle 56 is absent from the casing 10, by the base-plate 64 and a spring-urged locking bar 70 (Fig. 2) engaging the projecting gear 30. The locking bar 70 is supported by two posts 76 passing through respective tunnels 78 of the base-plate 64. On insertion of receptacle 56, the gear 30 is freed from the locking-bar 70 by co-operation between the posts 76 and respective pins 80, upstanding from the receptacle 56.
