Abstract: 1,226,554. Coated metal oxides. BRITISH TITAN PRODUCTS CO. Ltd. 14 June, 1968 [11 July, 1967], No. 31870/67. Headings C1A and C1N.  Coated metal oxide particles are produced by oxidizing or hydrolysing a metal halide (MX) in the vapour phase to form a suspension of MO particles in a hot gas, introducing a different metal halide (M<SP>1</SP>X) into the gas stream to dry coat M<SP>1</SP>0 on to the particles, recovering the dry coated particles, and subjecting them to a wet coating with a hydrous oxide or phosphate of a metal (M<SP>11</SP>). M is preferably Ti, M1 maybe Al, Si, Ti, and/or Zr, and M<SP>11</SP> may be A1, Ti, Ce, Zr, or Si. The oxidation of MX may be effected in a fluidized bed in the presence of a source of K, Rb or Cs, and together with AlCl 3  and SiCl 4 . Initial MO particles may be built up by introducing MX and O 2  through a plurality of inlets along the length of the reaction zone, before introducing M<SP>1</SP>X. M<SP>1</SP>X may be oxidized by introduction of O 2 , or by using excess 0 2  in the MX oxidation, or by reaction with the surface of the MO particles (the MX thus liberated may be oxidized to form another coating). The dry coated particles may be separated by filters or electrostatically or by passage through water to form a slurry. Wet coating may be effected by adding a soluble M<SP>11</SP> compound, e.g. a sulphate or chloride or alkali metal aluminate, to a slurry of the particles, and precipitating M<SP>11</SP>O by pH adjustment e.g. with NaOH or M<SP>11</SP> phosphate by adding a phosphate or H 3 PO 4 . The amount of M<SP>1</SP>0+M<SP>11</SP>0 may be 0À7 to 7%, or up to 15% for SiO 2 , and of phosphate may be 0.3 to 3%, by wt. of the coated particles. The particles may then be dried and fluid energy milled.

Abstract: 1,227,425. Lithium adducts. LITHIUM CORP. OF AMERICA. 3 April, 1968, No. 15956/68. Heading C2J. Lithium/conjugated polyene adducts are made by gradually adding the conjugated polyene (which term includes vinylidene substituted aromatic compounds) to a mixture comprising finely divided lithium dispersed in an inert liquid paraffin, an inert liquid ether and optionally a volatile aromatic hydrocarbon, maintaining the reaction mixture at below 25‹ C., adding a hydrocarbon to the reaction mixture which comprises a volatile aromatic hydrocarbon if not previously included in the mixture and removing unreacted lithium to form a solution of the adduct, said ether having been removed either prior to the addition of the hydrocarbon and after the addition of the polyene or after the addition of the hydrocarbon. The solution thus obtained contains 0À6-1À5 mol/l. of the adduct, 65-100% wt. of said adduct being constituted of a mixture of dimers and trimers of said polyene, the dimers constituting at least 1À5 times the trimers. The polyene is preferably added at a rate of 0À25-10 ml/min./gm. atom of lithium to a mixture containing 1À5-4 g. atoms/1. of lithium. The polyene may be isoprene, 1,3-butadiene, dialkyl butadienes, allocimene, myrcene, styrene, α- methyl styrene, 3-vinyltoluene, and 1-vinyl naphthalene. The inert paraffin may be a mineral oil, kerosene, iso-octane, n-heptane or n-octane. The ether may be glycol dimethyl ether or diethylene glycol dimethyl ether. Excess ether may be removed by purging with inert gas, by vacuum and/or warming. Suitable volatile aromatic hydrocarbons include benzene, toluene and xylene. A catalyst, in the form of a preformed lithium/conjugated polyene adduct, may be added to the reaction mixture. The adduct may be hydrogenated to form saturated hydrocarbons or they may be used as stereospecific catalysts for the polymerization of conjugated dienes, e.g. isoprene and 1,3-butadiene.

Abstract: 1,227,895. Video magnetic tape apparatus. GRUNDIG E.M.V. ELEKTRO MECHANISCHE VERSUGHSANSTALT INH. MAX GRUNDIG. 3 Oct., 1969 [4 Oct., 1968], No. 48659/69: Heading G5R. In apparatus for recording and reproducing television video signals, the tape/head speed synchronizing square-wave signals (Fig. 3a, not shown) (corresponding to the frame frequency), whose repetition frequency is at the lower limit of the recordable frequency band, are converted into pulses of decaying wave trains of a higher wave frequency. A capacitor 3 and the inductive head 4, Fig. 2 or 4, form a circuit resonant at the optimum response frequency of the playback head, so that each edge of the square-wave appearing across the resistor 2, Fig. 2, from the emitter of transistor 1 produces a pulse at that frequency. The circuit of Fig. 4 suppresses either the leading or the trailing edge of each pulse (Fig. 3c and 3d, not shown) so that the frequency of repetition of the pulses equals that of the square-wave. For reproducing the synchronizing signals, a tuned playback amplifier may be connected at the junction point between capacitor 3 and head 4, which then form a parallel resonant circuit. The usual H.F. bias may be applied at the junction between 3 and 4.

Abstract: 1,251,615. Token-freed apparatus. TRAVAUX INDUSTRIES POUR L'ELECTRICITE TRINDEL. 23 Feb., 1970 [28 Feb., 1969], No. 8588/70. Headings G4T and G4V. A time check system comprises a token 1, including a capacitor 4, recording means (8, Figs. 3, 4) to charge the capacitor by electromagnetic induction and reading means 24 responsive to the residual voltage on the capacitor at a later time. The token includes a winding 3 and a diode 5 in series with the capacitor 4, a resistance 6 in parallel with the capacitor and a magnetically operated switch 7, e.g. two flexible reeds of ferromagnetic material, in parallel with the diode. The token is validated by inserting the winding 3 in the air-gap of the recording electromagnet (9). The capacitor is therefore charged to a voltage whose value depends upon the time of charging, the voltage of the electromagnet and the time-constant of the capacitor-resistance circuit. This voltage decays at a rate dependent upon that time-constant, which can be made very long if the resistance is dispensed with. The token may be used to free an exit gate, e.g. of a car park, provided the capacitor voltage is above a predetermined value, so that the token is valid only for a predetermined time. On presentation at the exit the token is inserted into reader 24 so that winding 3 occupies the air gap 27 of electromagnet 25 whilst switch 7 is adjacent permanent magnet 29. Preferably two electromagnets are arranged so that a token can be read whichever way it is inserted. The operation of switch 7 by magnet 29 shortcircuits diode 5, so that capacitor 4 discharges through winding 3, producing a pulse in read-out coil 26. If the signal is sufficiently large, i.e. if a sufficiently short time has elapsed since the token was energized, the pulse triggers the monostable shaping circuit 31 which sends a rectangular signal to the OR gate 32. The latter transmits a signal which is amplified at 33 and actuates relay 34 to close contact 35 which, for example, lifts the car park exit barrier.

Abstract: 1,258,416. Valves. MAC VALVES Inc. 24 Dec., 1968, No. 42377/71. Divided out of 1,258,415. Heading F2V. In a solenoid-operated reversing valve having an inlet port 14, a service port 21, and an exhaust port (26, Fig. 2, not shown), control of flow between the respective ports is achieved by appropriately changing the state of a solenoid 13, the solenoid, when energized, causing downward movement of an armature 50 and hence corresponding movement of a valve member 38, such downward movement being effected in opposition to a spring 34. Interposed between the valve body 10 and the solenoid and armature, there is a floating polepiece 53 which, in the de-energized state of the solenoid, is urged by a spring 59 on to an abutment 58. Subsequent to the solenoid being energized and valve member 38 engaging the lowermost seating 22, the polepiece overcomes the force of spring 59, moves upwardly and, by virtue of the provision thereon of a shading coil 57, locks on to the armature and so serves to reduce the inrush current to a locking current. The valve member is comprised by an annular seal member 35 which is bonded to the valve stem 11. The diameter of the seal member is such that it can be force-fitted through one of the valve seats 18 or 22 whereafter it expands to a diameter greater than that of either of the seats. The terminal portions of the seal member are tapered.
