Title: Substrat ameliore pour support d'enregistrement a disque rigide; procede et appareil de fabrication d'un tel substrat
Inventor: COE THOMAS U
IPC: G11B5/82
Filed: 1985-06-19
Abstract: Un substrat comprend un disque (36) ayant deux faces opposées et frappé de sorte que les faces du disque aient une égalité et une uniformité de surface de l'ordre du submicron. Le disque frappé peut ensuite être recouvert d'une couche de matériau d'enregistrement et utilisé comme support d'enregistrement. L'appareil et le procédé de fabrication du disque frappé comprennent un dispositif de transport d'une pluralité de disques dans un trajet prédéterminé (56) une fois que les disques ont été façonnés par découpe d'ébauche ou par estampage. Les disques sont nettoyés avant d'être frappés et empilés dans des conteneurs qui peuvent être fermés en vue d'être transportés jusqu'à l'endroit d'utilisation. La frappe et l'emplacement des disques dans les conteneurs se font dans des conditions ambiantes hygiéniques et les substrats frappés qui en résultent sont dépourvus des imperfections et des défauts que l'on rencontre lorsque des techniques conventionnelles de formation de substrats sont utilisées.

Abstract: PCT No. PCT/US85/01977 Sec. 371 Date Aug. 8, 1986 Sec. 102(e) Date Aug. 8, 1986 PCT Filed Oct. 15, 1985 PCT Pub. No. WO86/02436 PCT Pub. Date Apr. 24, 1986.A spray cooling system for cooling a furnace for the melting or treatment of molten metal, and particularly the roof and/or sidewall of electric-arc, plasma-arc and ladle furnaces. Other types of metal treating furnaces and accessory equipment may also be cooled with the system of the invention. In the invention, spray headers and pipes (14, 16, 18) supply coolant to spray nozzles (70) distributed within a coolant space in a roof structure (10) to spray coolant against the working plates (22) of the roof. The spray pipes and headers also comprise part of the framework for the roof, resulting in a simple, lightweight, one-piece structure. A pump (56) is connected to evacuate the coolant from the coolant space, and thermocouples (58) are embedded in the working plates to monitor their temperature and operate controls to adjust the flow rate so that only the amount of coolant necessary to maintain a desired temperature is supplied to the roof. The sprays of coolant produce many small droplets which provide a large surface area for more effective cooling, and at least a substantial portion of the droplets are vaporized during cooling whereby the latent heat of vaporization of the coolant is utilized to provide a significantly increased cooling rate. Similar arrangements may be used to cool the delta and/or sidewall of the furnace. The method of cooling a furnace by directing sprays of coolant against the working plates is also disclosed.

Abstract: An awning assembly comprising an awning canopy rolled onto a roller spindle has two end caps which provide bearing support for the roller spindle and serve as hinge members which are pivotally attached to support brackets mounted on a supporting surface. Each end cap is provided with at least one bore extending parallel to the axis of the roller spindle and/or at least one bore extending laterally in a plane perpendicular to the axis of the roller spindle for the reception of a pivot pin. Each support bracket is provided with a pivot pin aperture which is capable of receiving the pivot pin, to thereby provide a hinged connection between the end cap and the support bracket. This enables a first part of the awning assembly to be raised and held in position by means of a hinged connection before a second part of the awning assembly is raised into its final position by rotating the awning assembly about the hinged connection.
