Abstract: A machine for driving-in tacks in the heel and side region of a shoe comprises a heel tack driver device (6) which jointly drives in the tacks for the heel region, and a side tack driver device (7) which together with a nipping driving-clamping device is movable in the longitudinal direction of the shoe on a working path following the shape of the joint. Each side tack driver device (7) has a mouthpiece having more than one but not more than four tack guides for simultaneously driving in a corresponding number of tacks (5). The working speed for side lasting is thereby increased by a multiple. In addition, each side tack driver device (7) can start its working path at the ball end of the joint (B) before the heel tack driver device (6) has freed the heel region (A). <IMAGE>

Abstract: To reduce the width of slabs from a reheating furnace to the width required in a finishing rolling train, thereby making it possible to feed slabs of only one width, or only a few widths, into the reheating furnace, the invention proposes rolling the slab in a width-reducing roll train in which the slab is subjected to traction such that plastic deformation occurs between the roll sets. In particular the width-reducing roll train has only one set of thickness rolls and has one or more sets of width rolls, thereby minimizing the length of the roll train and consequently reducing the lengths at the ends of the slab which are not subjected to the traction.

Abstract: An electrochemical detection apparatus is provided. The apparatus comprises a flow-cell having at least one active testing electrode, at least one reference electrode, and at least one counter electrode. Each electrode comprises a liquid impervious solid body having a bore extending therethrough with the electrode active surface located in the bore. The electrodes are arranged in a stack, electrically insulated from one another with their respective bores aligned so as to define a flow channel through which liquid to be detected can be passed. In a preferred embodiment of the invention at least one of the reference electrodes is actively driven to supply a stable reference potential against which other electrochemical responses can be measured. Various electrochemical responses are achieved by varying the construction, number and arrangement of electrodes in the stack, and the potentials applied to the electrodes. The detection apparatus has particular utility for use in monitoring chromatographic eluant.

Abstract: In a method of fabricating a fresnel zone plate, an end portion of a rod piece (29) is formed with a given diameter. Materials transparent and opaque with respect to an electromagnetic wave are alternately deposited on the rod piece (29) while the rod piece (29) is rotating, thereby to form a rod member with a multilayered structure. Each layer is uniform over the outer peripheral surface of the rod piece (29). The thickness of each layer is determined by design values of the fresnel zone plate. The rod member is inserted in a glass hollow cylinder and then the cylinder is filled with filling material. Then, the follow cylinder is sliced to form a slice piece (37). The slice piece is polished and fixed to a supporting ring (51), thereby to form a fresnel zone plate assembly (55). In the assembly 55, the slice piece (37) with a fresnel zone plate (3) supporting on a cylinder piece (53) formed by a hollow cylinder through filling material (54) is so arranged that the plate (3) is located at an opening of a through hole of the supporting ring (51), and the cylinder piece (53) is bonded to the supporting ring (51).

Abstract: A target body composed of a select target material is attached to a cooling plate for sputtering systems in such a manner that substantially no bubbles, pores or oxide layers are present in the ultimate solder joint between the surfaces joined together. A pre-soldered target body and a corresponding presoldered cooling plate are exposed, in a vacuum, to a temperature above the melting point of the solder utilized so that degasification of the liquified solder occurs and any oxide layers present are decomposed and purged from the solder. Upon cooling in vacuum, the solder resolidifies and excludes any air bubbles, pores or oxide layers. A frame body with a two-step recess, with a lower recess or opening snugly fitting about a cooling plate and an upper opening freely fitting about the solder joint can be used to practice this technique. A subsequent reflow soldering can likewise occur in vacuum at a temperature above the melting point of the solder utilized.
