Abstract: An alkali salt composition free from hydroxides, melting at a temperature in the region of or greater than 180.degree., and usable in its molten state as a negative electrolyte for accumulators comprising an alkali metal negative electrode and an alkali alumina separator, contains an alkali metal amide, at least one alkali halide and an alkali hydride. It may also contain aluminium amide.

Abstract: A process of integrating a photochromic substance, especially a spiropyran or a metal dithizonate, into a transparent substrate of polymerized organic material such as poly [ethylene glycol di-allyl di-carbonate] by thermal transfer, comprising applying the photochromic substance alone or with a solvent and/or thickening agent to the surface of a transparent organic substrate such as a lens disc, and heating until the photochromic substance is sublimed and then diffused and anchored in the organic material of the lens, preferably just beneath the surface to which it is applied. Preferably, the photochromic substance is initially carried on a temporarily support for application.

Abstract: Strengthening rods are positioned in mine levels and public works by introducing into a long bore made in a wall or other surface to be strengthened, a thermosetting resinous composition and a metal rod of substantially the same length as the bore, and rotating the rod at a rotation speed which causes it to heat up by friction with the composition to the hardening temperature of the composition so as to cause the rod to be sealed in the bore by the hardening of the composition.

Abstract: The invention is a method of assembly for a ball-and-socket joint of the preloaded type with automatic taking up of play, comprising a housing, a pivot, a bearing element disposed between these later and a locking ring. After the disposing in the housing of the various components of the joint, the latter is axially loaded until a predetermined value is obtained for the tilting torque, and once this value is obtained, the ring is crimped in the housing by means of punches acting radially, without alteration of the predetermined value of the tilting torque. Application of the ball-and-socket joint assembly in particular for suspension or steering of an automobile vehicle.

Abstract: A hollow three dimensional metal article is formed by cutting two identical flat metal blanks, forming a hole in one of the blanks and upsetting the metal around the hole to accommodate the head of a threaded hollow stud having a sealing collar without interference when the blanks are in face contact, placing the blanks in face contact while the stud is in place, welding the metal blanks together continuously around the entire perimeter of the superimposed blanks, and forcing liquid under pressure through the hollow stud until a precise preset maximum pressure is reached to inflate the blanks to their final three dimensional form. Optional steps include cutting off the portion of the three dimensional form in which the stud and the opening for the stud are located and welding a standard fitting into the opening thus created and the provision of other portions of the three dimensional object with other attachments and fittings.

Abstract: In the course of this method, an amount of expansible mixture is poured into a mould, after which the mould is obturated by means of a plug. A vacuum is created in the chamber of the mould by way of the plug so as to cause the foaming of the mixture. The vacuum is maintained for a period after the foamable mixture has filled the whole of the volume of the mould. At the end of the polymerization of the foamable mixture, the vacuum may be re-applied in the mould, preferably for several cycles, so as to cause the cells of the foam obtained to burst.

Abstract: Apparatus for automatic packaging of products such as concrete blocks in pallets formed by stacking layers of the blocks including a fixed table having supports along its sides and a moveable carriage disposed above the table on guide rails. The carriage is slideable having a translatory movement along the rails and carries gripping members for holding and releasing the blocks so as to move the blocks to form reserved spaces in the pallet for the tongs of a pallet handling device. The reserved spaces are formed in a given layer of the blocks in the pallet by causing the gripping members to hold and release the blocks in cooperation with detection and spacing devices for forming a given number of reserved spaces in the desired layer of blocks. The reserved spaces are created in a layer of blocks during the continuous movement of the carriage in the same direction.
