Abstract: A system configured for lifting or lowering a tool carriage device via a ladder climbing structure is described. The tool carriage device may be adapted to enclose and transport a payload and include a fall arrest grab with an overspeed brake to stop an uncontrolled descent of the carriage device. The tool carriage device may include obstruction sensors to detect an obstruction along the path of the carriage device.

Abstract: Climbing aid comprises a traction carriage (14) having a motor for hanging the user and for automatic movement along a ladder. Preferred Features: The drive has a current supply module formed as an exchangeable accumulator. The carriage is detachedly held on the ladder and moves along a side rail and/or along a guide rail (16) of the ladder. The drive torque of the motor can be adjusted to the weight of the user.

Abstract: Materials whose elemental constituents are selected from groups III and V of the Periodic Table are photochemically etched in a reducing environment. Etching is carried out by illuminating a halogenated hydrocarbon gas, e.g. methyl iodide, with ultra-violet light in the vicinity of the material. The reducing environment is provided by the presence of sufficient hydrogen to suppress the effect of any oxygen leaking into the system.Methods according to the invention may be used in particular in the production of opto-electronic devices.

Abstract: A Group III element Q selected from gallium, indium and thallium containing a Group VI element X selected from oxygen, sulphur, selenium and tellurium as an impurity can be purified by adding, to molten Q, an element M capable of forming with X a stable solid compound substantially insoluble in liquid Q. The stable solid compound can be separated and the purified Q used in the epitaxial growth of a semiconductor material such as indium phosphide. Alternatively, in a process for the epitaxial growth of a semiconductor compound of Q in molten Q, X can be removed in situ by the addition of a suitable element of the M-type.

Abstract: Semiconductor compounds which are alloys of group III-V compounds are grown by a liquid phase epitaxy method which includes heating growth apparatus in a reducing atmosphere while maintaining a solvent for the compound, a source of the group III-V compound and another element of the alloy separate from each other. After heating to reduce oxides, the element is added to the solvent, the source is brought into contact with the solvent and the resulting solution is brought into contact with a substrate to effect growth of the compound. Apparatus for carrying out the method is also described.

Abstract: A rotational moulding machine comprises six mould carriers mounted at 60.degree. intervals about a horizontal main axis of the machine on a turret which can be indexed about the main axis so as to bring each of the carriers in turn to loading/unloading, heating, and cooling stations of the machine. The machine comprises first and second driving wheels mounted for rotation about the main axis, and each mould carrier comprises first and second driven wheels rotatable to rotate a mould mounted on the carrier about first and second rotational axes. Each mould carrier is pivotally mounted on the turret, and the machine comprises clutch means whereby each carrier can be moved pivotally between a first position in which the two driven wheels of the carrier frictionally engage the two driving wheels for rotation thereby, and a second position in which the two driven wheels are out of engagement with the two driving wheels.
