IPC: C04B11/30
Filed: 1926-05-07
Abstract: 264,711. Cadre, P. May 7, 1926. Cements, Portland and Roman, processes and materials for making. - In the manufacture of cements by mixing a form of calcium sulphate. a slag or a puzzolanic material, and cement clinker, the ingredients are separately completely dried, pulverized, and cooled before being mixed. If gypsum is used as the source of calcium slilphate it should be subjected to a series of alternate pulverizing and drying processes until its total moisture content does not exceed 5 per cent. Suitable proportions of the ingredients are 80 per cent of slag or puzzolanic substances, 15 per cent of calcium sulphate, and 5 per cent of cement or cement clinkers. The slag &c., should be ground to leave a residue of 7-10 per cent upon a sieve of 4900 meshes to the square centimetre and the calcium sulphate should be more finely ground so that equal numbers of particles of the two ingredients are present.

Abstract: 1,149,223. Toy vehicle. LESNEY PRODUCTS & CO. Ltd. 29 Feb., 1968 [14 March, 1967], No. 12008/67. Heading A6S. A steerable, transverse axle for a toy vehicle comprises an axle placed between two vertical pins longitudinally disposed on the chassis or base and at least one resilient member which is arranged to tend to maintain the axle perpendicular to the length of the chassis or base, manual pressure causing this member to resiliently deflect, and to allow the axle to pivot about a vertical axis disposed between the two pins. Two resilient members are preferably employed, both being directed from a part which they are integral with or attached to, in such a way that they bear against the axle at opposite sides of the two pins. The members may be rectilinear (of Fig. 9 parts 16), or L-shaped (of Fig. 3 parts 11) In the former case, the two members are held in a V-shaped configuration, and are integral with the block 17, which is fixed to the chassis. In the latter, the members are attached to the end of a strip-shaped member of the same resilient material 9, and that part of this strip which lies over the axle is arched. The resilient strip 9 can also be arranged so as to bear down on this axle alone or on this axle and another, to form a resilient suspension. The two pins may both be attached to the base, or the front one may be attached to the resilient member. The resilient member is normally made of a plastic material. The amount of pivot aliowed to the axle is governed by the size of slits in the chassis, through which the axle passes at each side.

Abstract: 1,137,669. Image converter tubes. W. HEIMANN. 18 March, 1966 [26 March, 1965; 21 Sept., 1965], No. 12086/66. Heading HID. In an image converter tube in which electrostatic electron lenses are used to form an image of a photocathode, pin-cushion and curvature of field-type distortion is reduced or suppressed by imposing a radially extending potential difference between a small central area and the edge of the surface on which the photo-emissive layer of the photocathode is disposed. This potential difference may be applied by supplying a current to the centre of the photocathode surface and extracting it at its edges using transparent conductive coatings. As shown, a metal ring 2 is provided on a glass support 5 and connected via lead 3 to a battery. A transparent conducting coating 1, e.g. of SnO 2 , is applied to the support 5 within the ring 2. The ring 2 and coating 1 are covered everywhere except over a small central area, which as shown in Fig. 4 may be a serrated region, by a transparent insulating coating 4, e.g. SiO 2 , a further transparent conducting coating 1a, extending to outer metal ring 3 connected to the other battery terminal, being applied over coating 4. The coating la may also support the photo-emissive layer. In another embodiment, Fig. 5 (not shown), a glass support is coated with, successively, a transparent conducting coating, a transparent semi-conducting coating, and a transparent coating having a high resistance whose thickness or homogeneity varies so as to produce a voltage curve that varies quadratically with the radius from the centre to edge. Alternatively, variation in homogeneity of the semiconductor coating may be used to produce the required voltage curve.

Abstract: 259,498. Mond, A. L., (I.G. Farbenindustrie Akt.-Ges.). May 13, 1926. Magnesium chloride. - In the production of anhydrous magnesium chloride by the action of chlorine on mixtures of oxidic magnesium compounds and a reducing agent at a temperature below the melting point of the magnesium chloride, e.g. at 500-550‹ C., substances are added to the mixed magnesium oxide &c. and reducing agent which render the mixture highly porous when heated, and thereby accelerate the production of magnesium chloride. For instance, magnesium oxychloride may be added to the reaction mixture, or the magnesium oxide &c. in the mixture mav be transformed into an oxychloride by the addition of fused hydrated magnesium chloride or of magnesium chloride lyes. The mass then obtained is self-binding, is not fused at the temperature of the reaction, and acquires the required porosity on heating by loss of water. Additionally, the carbon &c. used may be wholly or partly replaced by sawdust, peat, lignite dust, &c. and the mixture be dried, e.g. at 350‹ C., before chlorination. By increasing the amount of sawdust &c. in the latter mixture, the amount of magnesium chloride added to a given quantity of magnesium oxide may be reduced. Examples of the amounts of the various ingredients used in the above mixtures, and of the after treatment of the latter, are given.

Abstract: 372,547. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Warrington, A. R. van C. ; 4016, Dayton Road, and Traver, O. C. ; 1015, Childs Avenue, both in Drexel Hill, Pennsylvania, U.S.A.) April 28, 1931, No. 12514. Convention date, Aug. 28, 1930. [Class 38 (v).] In protective arrangements employing relays whose action is dependent on line voltage, in order to ensure operation of such a relay under short-circuit conditions when the line voltage almost disappears the energizing current for the voltage operating winding is arranged so as to be resonant to the frequency of the circuit when the voltage is below a predetermined value but to prevent excessive current in the voltage winding at normal line voltages, the resonance of the circuit is impaired for voltages above a predetermined minimum. As shown in Fig. 1, the voltage winding of a relay 9 is connected in series with a condenser 17 across the secondary of the voltage transformer 16. With voltages of a small value the inductance of the voltage coil is such that with the capacity 17 it forms a resonant circuit but with higher voltage values approaching normal line voltages the saturation of the core 18 of the voltage winding impairs the resonant properties of this circuit. If the inductance of the voltage winding is not sufficient to produce resonance at low voltage values an additional inductance may be connected in parallel, Fig. 2, (not shown). An alternative arrangement is shown in Fig. 5, in which a resistance 20 having a high positive temperature coefficient such as a metal filament incandescent lamp is placed in series with the voltage winding 13, the condenser 17 being paralleled with this arrangement across the mains 6. Resonance again occurs at voltages below a predetermined minimum but with higher values the automatic increase of the resistance 20 impairs the resonant qualities of the circuit. In a further alternative, Figs. 6 and 7 (not shown), a resistance of negative temperature coefficient such as one of the carbon-carborundum type described in Specification 292,110, [Class 38 (iv), Electric supply and transmission systems &c.], may be employed as a phase to the voltage coil in a series resonant voltage circuit.
