Abstract: A splice frame intended to be attached to at least a first end portion of a conveyor belt of a type including a body made of flexible material, inside of which is housed a reinforcement including cables. The splice frame includes retaining members having at least one body configured to extend at least partially transversely with respect to the conveyor belt and anchoring members configured to engage with at least part of the cables so as to secure the body of the retaining members to the first end portion of the conveyor belt. The retaining members include a retention interface for retaining one or more fasteners of a splicing device intended for splicing the first end portion with a second end portion of the conveyor belt when a tensile force is applied between the splicing device and the conveyor belt.

Abstract: A vitreous semiconductor supporting structure obtained by connecting semiconductor layers to a vitreous support constituted by at least two glasses. The semiconductor layers are constituted by an electrically and optically active n-ary III-V compound layer (3) and optional complementary layers for passivation (4), index adaptation (6), and protection (7). To keep the active layer in a compression state and optimize its electrical properties, the structure includes at least two glasses, an intermediate glass (15) providing thermoelastic properties and a supporting glass (16) providing a high softening temperature.

Abstract: The photocathode is of the type which comprises a photo-emissive layer consisting of at least an active layer of the P-type, a solid support for said semiconductor of a material which is transparent to radiation, a layer having a bonding glass for the photo-emissive layer on the support. The invention is characterized in that the support comprises two parts situated one on top of the other and which are bonded together, namely a thick second part (thickness for example 5 mm) of a type of glass having properties of thermal expansion which are substantially identical to those of the bonding glass and a part in the form of a disk-shaped first part (thickness for example 1 mm) of a material having softening and transition points which are much higher than those of the bonding glass and of the glass of the thick part.
