Title: Apparatus and systems comprising a clad superconductive oxide body, and method for producing such body
Inventor: SHERWOOD RICHARD CURRY
IPC: H01B12/02
Filed: 1988-03-29
Granted: 2002-10-22
Abstract: A method of producing clad superconductive oxide wire, tape and the like is disclosed. The method comprises forming an intermediate body by surrounding a quality of the oxide powder (e.g., Ba2YCu3O6.9) with an appropriate cladding material (typically normal metal), reducing the cross section of the intermediate body by an appropriate technique (e.g., drawing or rolling), and heat treating the elongated body such that substantial sintering of the powder results, such that, after completion of the heat treatment, the sintered oxide has a composition that is associated with superconductivity in unclad bulk samples of the oxide, and such that the body manifests superconductivity at a temperature above about 77K. These conditions require that at least the portion of the cladding that is in contact with the oxide powder is substantially inert with respect to oxygen and the oxide under the conditions of the heat treatment, and that at least a portion of the oxide is in contact with an effective concentration of oxygen during at least a part of the heat treatment such that the oxide powder can take up oxygen. Silver is the currently preferred inert normal metal. Exemplarily, Ag can be used to provide a diffusion barrier, with other normal metal (e.g.. Ni and Cu) surrounding the diffusion barrier, or the cladding can consist substantially of Ag. Various techniques for preventing oxygen loss and/or restoring lost oxygen from the powder are disclosed. Advantageously the elongated body is appropriately shaped (e.g., wound into a helical coil) prior to completion of the heat treatment. Elongate bodies produced according to the invention can advantageously be used as superconductive magnets, and in a variety of other apparatus and systems.

Abstract: PRESS FOR MOLDING ARTICLES FROM POWDERED MATERIALS AND DRIVE MEANS THEREFOR                  ABSTRACT         A press is described which is particularly suitable for the production of precision moldings from pulverized materials.  The press is provided with a frame 3 in which a draft frame 5 and a platen 4 acting together provide the axis, and are connected to one another by means of a mechanical drive, preferably a toggle drive system, for relative movement to form a main press ram.          In the main press ram, between the movable draft frame 5 and the platen 4, a hydraulic subpress 12 is arranged together with at least one additional axis, preferably however with several such axes. Control and regulation of the timing and extent of the working movement of each axis in the hydraulic subpress 12 are made to depend, through a control system 22-33, on the working movement of the main axis formed by the draft frame 5 and the platen 4 of the mechanical press 2.

Abstract: Method for providing a design pattern on a metal stencil and metal stencil having a patternable covering layer ABSTRACT            The invention relates to a method for forming a pattern in a metal stencil or screen which is covered by a covering layer in the form of a resist material.            The pattern is formed by locally removing the lacquer or resist from the screen's perforations with use of a beam of high energy radiation such as a laser beam.            The resist material used is filled to a high concentration with metal powder to increase the thermal conductivity thereof.            The invention also relates to a metal stencil provided with such a metal-filled covering layer which layer is patternable with use of a radiation beam.

Abstract: ABSTRACT OF THE DISCLOSURE          An electrical terminal has two elements, one of which is formed by a metal coupling device, a first ring connected to the coupling device and a second ring connected to the first ring by means of a narrow lower link, so that the second ring is externally projecting beyond the first ring, and the other element is formed by a hollow, tubular insulating sleeve internally featuring a flaring forming an initial step, followed by an annular recess, a second step almost centrically located with respect to a cylindrical end section, and assembled by introducing the second ring in the sleeve until it is positioned in the annular recess and resting against the first step. After connection to the lead by crimping the first ring, the sleeve is moved axially so as to   cover the coupling zone, i.e. until the second ring fits into the end portion of the sleeve against the second step.

Abstract: Products having a viscous or pasty consistency, or those dispensed as foams from a container (1) provided with a pushbutton (13) the actuation of which causes the ejection of a dose of product, are never, in practice, completely evacuated from the ejection conduit (14) made in a movable portion (9) bearing the pushbutton (13) and adapted to the outlet of the container (1). Hence they often threaten to escape from this conduit (14) and soil the container (1). To overcome this disadvantage, the invention proposes that the conduit (14) discharge into a chamber (40) defined by a fixed portion (10) attached to the container (1) and with the movable portion (9) comprising a dispensing cap (8); the chamber (40) opens to the outside via an opening (38), and the movable portion (9) includes a needle (27) capable of closing this opening (38) in the position of repose of the pushbutton (13) and of freeing it upon actuation of the pushbutton.

Abstract: ABSTRACT OF THE DISCLOSURE      In the case of this process, the crankshaft is assembled from individual formed pieces each comprising a crank web and two journal projections.  Journal parts belonging together are slid onto a joint sleeve which is plastically deformed by applying pressure, whereas the journal parts themselves are only deformed elastically, and as a result of their spring-back, they provide the necessary adhesion for the connection.     Prior to being joined, the bearing journals and crank journals may be provided with bearing bushes of a material having better tribological properties and/or undivided roller bearings and also undivided connecting rods.  Lubricating channels provided in the webs, annular spaces remaining between the sleeves and journals and longitudinal grooves provided in the former permit continuous lubrication of the bearing faces.  Key teeth provided at the parts to be joined ensure accurate orientation of the parts relative to each other.  The expanding pressure devices may be inserted into the interior of the sleeves through apertures provided in the webs.  The process is also suitable for producing crankshafts whose bearing and crank journals overlap in the axial direction.  Further stages of the process permit a reduction in the number of operations and relate to the arrangement of intermediate layers which improve adhesion or the leakproofness between the parts.

Abstract: ABSTRACT OF THE DISCLOSURE           A system and method for distributing lottery tickets includes a large number of remote, ticket-dispensing units which are connected intermittently, e.g., once each day or week to a central computer.  The units record the numbers of tickets sold and transmit the sales data to the central computer, which in turn performs all the necessary accounting functions.  Sales reports and invoice data may be sent by the central computer to each unit for printing, which avoids the need to mail the reports/invoices.  The tickets are stored in fan-fold form and are burst, rather than cut, apart for dispensing.  The tickets are dispensed at one end of the unit which faces the customer.  A control panel for the vendor is located at the opposite end.          Tickets of different length may be dispensed with an imprint of the vendor's name.
