Abstract: 146,477. Krupp Akt.-Ges., F. May 6, 1916, [Convention date]. Gyroscopic apparatus.-Relates to means for readjusting or maintaining the axis of a body, such as a sighting-telescope C<3>, which is normally stabilized by gyroscopic action, but which is liable, owing to precessing movements caused, say, by friction in the bearings of the gyroscope, to be moved out of the true line of sight. The gyroscope B rotates about a vertical spindle carried in stirrups d<3>, d<4> mounted on a non-magnetic twopart ring D, D<1> swivelling on an axis D<2>. The other ring C of the cardan suspension is pivoted about two stub-axles C<1>, C<2>, the former of which carries the sighting-telescope C<3> or other instrument to be stabilized. Two magnetic armatures G are mounted on the upper half D<1> of the non- magnetic suspension ring, and are acted upon by the pole-pieces e<3> of two electro-magnets F, F<1> enclosed in a housing H formed in the upper part of the casing A, A<1>. In the normal position, there is but a slight overlap between the armatures G and the pole-pieces e<3>, but by increasing the current supplied to the magnet winding F, relatively to the winding F', a torque will be applied tending to rotate the gyroscope in the direction of the arrow X, and this, by gyroscopic reaction, will rotate the telescope C<3> about the axis C' so as to elevate the eye-piece. The leads of the magnet windings are connected to an external switch which closes the circuit and regulates the current fed to one or others of the electro-magnets as required.

Abstract: 443,536. Glass manufacture ; transparent plates; building-blocks &c. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, & CIREY, 1<bis>, Place des Saussaies, Paris. July 4, 1935, Nos. 19146 and 19147. Convention dates, July 4, 1934 and June 28, 1935. [Class 56] [See also Groups X, XI, and XIV] A method of making a composite tempered object consists in permanently uniting a number of pieces or elements of tempered glass under conditions, for example of temperature, such that modification of tempering is avoided. The tempered elements may be united by adhesion by using substances such as resin, resinous pitch, or artificial resinous compounds. Alternatively, the parts which are in contact with one another can be coated with metal by means of the process described in Specification 413,900, and the metallized parts can be united by soldering, care being taken that the temperature of the joint during soldering does not exceed 400‹ C. Articles can be constructed by incorporating tempered glass elements with assemblies of elements composed of other materials, such as metal or untempered glass, or both. A plane glass plate of large dimensions may be made by joining a number of rectangular tempered elements edge to edge. A hollow block for building walls, partitions, &c. can be made by joining two mouldings C, D, Fig. 5, of tempered glass by means of solder S applied to metallized edges M. A hollow paving block to be set in concrete can be constructed similarly. A container can be made by uniting panels b, Fig. 2, and a bottom d, all of tempered glass, which are metallized along their edges c. Similarly, a compartmented dish may be constructed by joining strips e, f, Fig. 3, of tempered glass to a bottom g. A globe or lantern can be made by uniting flanges j, Fig. 4, to a cylinder i, all of tempered glass, by means of an adhesive capable of resisting heat.
