Abstract: The lathe of the present invention includes a bed having a slide surface in the form of a dovetail and two heads for mounting a work piece on the bed. The bed is a die-shaped section with one side extending in the shape of a dovetail. The heads are two portions formed from the same die-shaped section having one side in the form of a dovetail, complementary to the dovetail of the bed. The dovetail of each head and the dovetail of the bed are slidable one within the other.

Abstract: An open-shed Jacquard machine comprising multiple harness cords on each side of the layer of warp yarns of a loom, and each cord provided with an eyelet through which a corresponding warp yarn passes, the shed opening system comprising multiple modules each having pulleys respectively receiving in its groove one of the harness cords, harness cord displacement mechanisms on the modules to rotate the pulleys through angles sufficient to lift the cords, the shed opening modules being arranged on the loom in series of spaced rows with their displacement mechanisms facing away from each other and their pulleys facing toward each other, and the rows being progressively offset from each other in directions parallel to the warp yarns.

Abstract: The invention relates to sewing machines, wherein the needle is mounted on the needle bar with both a transverse offset and an angular offset with respect to the axis of the needle bar. It may be applied to sewing machines for both domestic and industrial use.

Abstract: A process for measuring the temperature of a bath of molten metal comprises bringing a heat sensitive element into contact with the molten metal whereby the element, which comprises an electrically insulating material is, progressively destroyed by combustion when in contact with the bath. The duration of combustion of a predetermined length of this insulating material is measured, from which duration the temperature of the bath can be ascertained. The duration is timed by means of electrodes immersed within the insulating material, which electrodes terminate at different levels therein and are used to activate or deactivate a counter for counting the pulses of a clock arrangement.
