Filed:

Dec 15, 1975

Appl. No.:

5/640909

Inventors:

Bohdan Wolodymyr Siryj - Cinnaminson NJ

Assignee:

RCA Corporation - New York NY

International Classification:

B65G 4724

US Classification:

198395

Abstract:

A right parallelepiped object is located on an upwardly inclined moving conveyor having a low coefficient of friction and spaced apart cleats. A dimension to be oriented of the object is in one of three known orientations: along the conveyor, across the conveyor, or normal to the conveyor. Depending on the initial orientation and the desired orientation, the object is in one case rotated on the conveyor by a pivotally movable arm an amount in excess of 45. degree. and then oriented to complete a full 90. degree. rotation by one of the cleats advanced by the conveyor. Alternately, the object is moved off the conveyor onto a platform which is thereafter tilted such that the object falls to a given one of its other sides, thereafter being in its desired orientation.

International Classification:

G03D 700

US Classification:

354299

Abstract:

A thermal processor in an apparatus for heat development of a fixed photographic image on a photographic film wherein the film includes a latent image formed on an emulsion layer coated on a film base. The apparatus comprises a housing arranged to receive uniformly heated flowing air. Porous members responsive to the air flow are disposed adjacent both surfaces of the film to uniformly distribute the heated air to the surfaces of the film at a predetermined pressure. The porous members are disposed at a spacing from the respective film surfaces such that the pressure of the gas supplied to the film establishes a gas bearing to support the film as it passes through the processor. The spacing is also arranged such that heat is transferred from the processor to the film essentially by heat conduction to develop the fixed photographic image on the film.

International Classification:

G11B 1722

US Classification:

369 38

Abstract:

Apparatus for presenting a desired one of a stack of N information disks with a selected one of its two information surfaces in a desired orientation to an information utilization device. The apparatus includes a mechanism for rotating the disks as a stack to put the selected surface in the desired orientation, for translating the disks as a stack to position the desired disk opposite the utilization device and for translating the desired disk into the utilization device.

International Classification:

G11B 338

US Classification:

369249

Abstract:

A low-friction slide apparatus for use with the translation stage of an optical disc recording/playback system is disclosed. The apparatus includes a rail which is fixed in position. The rail includes porous strips affixed to two orthogonal sides along its longitudinal dimension. A plurality of passages between the rail and the porous strips permits air to be forced outwardly through the pores of the strip material. The slide member, which is movably mounted on the rail, has bearing surfaces adjacent the porous strips attached to the rail. Permanent magnets mounted along these bearing surfaces maintain an attractive force between the slide and the rail, countering the force direction of the air flow, thus providing a low-friction bearing film of compressed air. A linear motor included in the rail and slide member induces motion of the slide along the rail. In a second embodiment, the attractive force which counters the force direction of the air flow is provided by a vacuum in the rail which pulls the two slide member bearing surfaces toward the rail.

US Classification:

74 8915

Abstract:

Apparatus for converting rotary motion of a screw into linear motion includes three circumferentially spaced nut segments each resiliently mounted for displacing in a radial direction normal to the screw axis. A thin flat plate spring member provides a resiliency to the nut segments in a direction normal to the screw axes. The nut segments include a set of parallel triangular screw threads with the roots undercut and the crests removed for averaging out the contact between the nut segments and the screw to an area along the pitch diameter of the screw.

International Classification:

G11C 1304

US Classification:

369 38

Abstract:

A high speed data storage and retrieval system includes a disc storage module, a reader and a disc changer apparatus. Disc records enclosed in protective cartridges are transported between the reader and the storage module by the changer apparatus. The reader includes two mechanical systems--a system for receiving, securing and spinning a disc while it is enclosed in the cartridge and a pair of read heads which retrieve data stored on the surface of the disc. The storage module includes a plurality of storage locations for storing the discs. The changer apparatus comprises a carriage with a drive mechanism for driving the carriage the length of the storage module and at least two carriers for transporting discs with independent drive mechanisms. The carrier drive mechanisms drive the carriers in a direction normal to the direction which the carriage is driven. Simultaneous movement of the carriage and carriers permits high speed access of data.

Assignee:

RCA Corporation - New York NY

International Classification:

G03D 700

US Classification:

354299

Abstract:

The length of film being developed by heat is supported on a fluid bearing by heated air which passes through two porous elements which serve as the walls of the film passageway. The air is preheated and the porous elements themselves are separately heated in order further to raise the temperature of the air bearing.

RCA Corporation - New York NY

International Classification:

G03D 700

US Classification:

354299

Abstract:

A length of photographic film being developed by heat is supported on a fluid bearing by heated air which passes through two porous elements which serve as the walls of the film path. The air is preheated and the porous elements themselves are separately heated within and beyond the film passageway in order further to raise the temperature of the air bearing. The edges of the path are heated to a higher temperature than the center of the path to thereby compensate for edge effects at the film. The added heat at the edges of the path provide more uniform heating of the film across the width dimension of the film.
