Title: Improvements in or relating to ferrite particles and process for manufacturing same
Inventor: IWASE KEIZO
IPC: H01F1/11
Filed: 1966-02-04
Abstract: 1,142,214. Spinel ferrites. NIPPON ELECTRIC CO. Ltd. 4 Feb., 1966, No. 5107/66. Heading C1A. [Also in Division H1] Isotropic spinel type ferrite particles are produced from an aqueous solution containing Fe<SP>2+</SP> ions and M<SP>2+</SP> ions, where the atomic ratio Fe/M is at least 2, by adding an alkali metal or ammonium hydroxide in an amount of 0À55-3 equivalents of the acid radical in the solution to precipitate the hydroxides at a pH of at least 6À5, and then oxidizing the suspension at 60-90 C. by bubbling air or O 2  until the hydroxides disappear and spinel ferrite is precipitated. Alternatively, the amount of alkali added and the temperature may be correlated with reference to a diagram (Fig. 2, not shown) in which case the temperature may be as low as 20 C. (for Co, Mn or Zn ferrite only). M may be Mn, Zn, Co, Mg, Ni, or Cu. The solution may be of a sulphate or chloride and have a metal ion concn. of 0À05-0À8 mol./l., pH adjustment may be effected with NaOH, KOH, LiOH or NH 4 OH. The precipitated ferrite may be used as seed in a subsequent process. The product may be dehydrated with alcohol or by heating at 60 C. in N 2 , and may be pulverized at below 40 C. under reduced pressure. A surfactant may be introduced before drying. The product has the formula M 1-x Fe 2+x O 4 , said to be a solid solution of Fe 3 O 4  and MFe 2 O 4 , and the particles have diameters of 0À05-1 micron. When heated at below 500 C. in air it converts to M 1-x Fe 2+x  O 4+0À5x , a solid solution of γFe 2 O 3  and MFe 2 O 4 . It may be compacted at 2À5 tons/cm.<SP>2</SP> and sintered e.g. at 950-1300 C. in N 2 .

Title: An improved vehicle signalling installation
IPC: B60Q1/26
Filed: 1958-02-18
Abstract: 882,711. Road traffic signals on vehicles. PREPER, W. R. C. Feb. 18, 1958 [Feb. 18, 1957; Nov. 23, 1957], No. 5296/58. Class 118. A " stopped " signal on a road vehicle is controlled by conjoint operation of the hand brake and an independently actuated manual member, the arrangement being that release of the hand brake suppresses the signal and returns the manual actuating member to an inoperative position. The hand brake H operates a sliding contact r and tends to move it (via spring t) to engage with contact p. A blocking member s prevents this action unless the solenoid e is energized by a bell push d. The member s interposes itself between p and r when the hand brake is released. Instead of a solenoid arrangement the blocking member 8 may be actuated by a self-restoring mechanical means, possibly coupled to the hand brake to effect its release.
Patent GB-446993-A (GB)
Title: Improvements relating to electric switches for controlling alternating currents
IPC: H01H9/56
Filed: 1935-02-19
Abstract: 446,993. Spanking-preventing in switches. ANDERSON, J., 137, Aldridge Road, Perry Barr, Birmingham. Feb. 19,1935, No. 5303. [Class 38 (v)] A switch adapted to break an A.C. circuit at the zero of its cycle comprises a latched contact lever a adapted to be moved into its open position about its pivot d by a spring e when the catch is released, a projection f on the lever a then being guided in a spiral slot m of a disc l driven by a series synchronous motor suitably timed. The projection f is normally held by a hook q on a lever g pivoted at h and the lever g is normally held by a lever i pivoted at j. A spring n connected at one end to the rotarv disc and at the other to a rotatable collar o on the end of the arm g tends to pull the lever g first one way and then the other as the disc l rotates, but both movements are normally prevented by the projection f and the arm i respectively. On movement of the lever i, however, either by hand or by an electromagnet k, the spring n when it is brought to the right of the axis h moves the lever g so as to release the projection f, which then moves downwards to engage the edge of the slot m. As the disc l rotates, the projection follows the slot, eventually emerging at the open end, the contacts in the meantime having been separated just when the A.C. current was at zero.

Moisture condenses in chambers [5] downstream of the plates 51 and is collected in chambers separated from the condensation chambers by multi-apertured walls 52, 53 and containing a heat-resistant filter material 54. The moisture is collected in a reservoir 6 with a drain cock 7. The coolant may be engine cooling water circulated by a pump 16 or air forced into the pipe (15), Fig. 6 (not shown), or the tube (17), Fig. 5, by a motor-driven fan (18) or by forward movement of a vehicle on which the apparatus is mounted. Pipes (13), Fig. 3, may extend through the chamber 1 from opposed parts of the coolant jacket (9'). The interior of the chamber 1 may be as described in Specifications 1,073,143, 1,160,388 and 1,321,393.
Patent GB-711279-A (GB)
Title: Elastic linear copolyesters and process of making them
IPC: C08G63/181
Filed: 1951-03-06
Abstract: Elastic co-polyesters are produced by melt polymerization of a glycol HO (CH2)n OH (where n = 2-6) an acid HOOC CH2 X CH2 COOH where X is a linear chain of 4-9 atoms, not more than three of which may be oxygen the remainder being saturated hydrocarbon carbon atoms which contain not more than 3 carbon atoms as side chain substituents, any two oxygen atoms being separated by at least two carbon atoms and 30-44 per cent. by weight of the total acid component of terephthalic, bibenzoic, ethylene -bisp-oxybenzoic, tetramethylene -bisp oxybenzoic or 2, 6-naphthalic acid.  The glycol is present in stoichiometric excess.  Acyclic acids mentioned include inter alia suberic, sebacic, azelaic, oxydibutyric, 5-ox- 1, 10- decanedioic, undecanedioic, 4-n-propyl suberic.  Mixtures of aliphatic acids and of aromatic acids may be employed.  The acids may be employed as methyl esters.  When the reaction mixture reaches the desired intrinsic viscosity it may be extruded to form chips which may be melted to form shaped articles.  Yarns or films may be drawn with relaxation periods and may be heat treated to prevent tackiness, to produce desired elastic properties and to reduce shrinkage on heating.  In examples (1), 120 parts of dimethyl terephthalate, 280 parts of dimethyl sebacate and excess glycol are heated to produce a polymer of intrinsic viscosity 1.0.  This is drawn and relaxed to a net draw ratio of 3.5, and then aged.  (2) and (3) copolyesters are produced from the dimethyl ester of ethylene bisp-oxybenzoic acid and dimethyl sebacate with excess ethylene glycol, and are spun into fibres.  (4) Tetramethylene bisp-oxy benzoic acid, dimethyl sebacate and ethylene glycol are employed. (5) The raw materials are dimethyl bibenzoate, dimethyl sebacate and ethylene glycol.  (6) The materials used are terephthalic acid; 5, 8- dioxo- 1, 12, -dodecane-dioic acid and ethylene glycol.  The physical properties of yarns prepared from the copolyesters of the invention are summarized and a list of articles for which they may be used is given.  The polyesters may also be used for adherent elastic coatings, elastic film, heat shrinkable bottle covers, safety glass interlayers, oil-resisting gaskets, flexible tubing or wire coating.
