Patent EP-0067486-A2 (EP)
Inventor: EVERETT MONTAGUE
IPC: G03D3/08
Filed: 1982-06-10
Abstract: Apparatus for transporting carriers such as film carriers includes a substantially cylindrical, open sided carrier which retains spaced-apart parallel sheets of photographic film within the cylinder. A plurality of horizontal open-topped chemical troughs are disposed side-by-side with a second lip of each trough in the series being disposed adjacent a first lip of the suceeding trough in the series. The film carrier is deposited adjacent the first lip of the first trough. A transport mechanism in each trough rolls the carrier along the inner surface of the trough so that it is ejected over the second lip and drops into the next succeeding trough in the series. The carrier is finally ejected over the second lip of the last trough into a drying chamber where it is subjected to a flow of heated air. The processor is particularly suitable for processing sheets of intraoral dental film.

Abstract: An optical device for controlling a light beam, for example, in an optical disc player, has a lens (6) acting on a light beam and carried by a movable member (14) to which a bar magnet (19) is also attached, and a magnet (20) having a closed ring shape extends around the bar magnet (19) so that the magnetic fields of the bar magnet (19) and the ring-shaped magnet (20) provide magnetic reactive forces tending to maintain the movable member (14) and the lens (6) thereon in a stable balanced position. First and second electromagnets (25a, 25b, 26a, 26b) are selectively energized to interact with the bar magnet (19) for causing respective movements of the movable member (14) and lens (6) in the direction of the optical axis of the lens (6) for focusing the light beam at a record medium surface, and in a direction at right angles to the optical axis, for example, for varying the position on the record medium surface where the focused light beam impinges.

Abstract: This invention relates to a method and apparatus providing a common handshaking protocol for the 201, 202 and 208 modems in long distance data transmission. 
<??>According to the present invention a novel handshaking sequence trains up any echo canceller 74 in the circuit, detects the presence of any echo suppressor 82 and uses a conventional signal preamble in the presence of echo cancellers 74 and a sacrificial carrier sequence in the presence of echo suppressors 82. As in the prior art, a ringing signal is applied to an answer modem 40 in response to a signal from an originate modem 30. The answer modem 40 is connected to the communication line after receipt of the ringing signal, and an answerback tone is transmitted from the answer modem to the originate modem after a period of silence following connection of the answer modem to the line. After receipt of the answerback tone, the originate modem 30 is connected to the communication line. In accordance with the invention, this is followed by a period of silence that is sufficiently long to reactivate any echo suppressors 82 in the communication line. Thereafter at least two training sequences are transmitted, one from the originate modem 30 to the answer modem 40 and the other from the answer modem 40 to the originate modem 30, each training sequence being sufficiently long to train up any echo canceller 74 in the line. The lengths of the training sequences as received are compared with their lengths as transmitted to determine if the length of the sequence was shortened by an echo suppressor 82. If the length of the training sequences as received are significantly shorter than their lengths as transmitted, a sacrificial carrier is transmitted at the beginning of each transmission of data in a new direction. In the event the training sequences as received are not significantly shorter, each transmission of data in a new direction begins without a sacrificial carrier. As a result, greater data throughput can be achieved in the absence of echo suppressors 82 and errors can be avoided while echo cancellers 74 are being trained.

Abstract: A method of forming an extrusion die comprises forming an extrusion aperture 11 in a die piece 10, forcing a flowable materiat 14 partly through the extrusion aperture so that the leading surface of the material becomes deformed in the extrusion direction, and then removing the exposed surface of the extrusion aperture 11. by chemical or electro-etching, so that the effective axial bearing depth of the extrusion aperture at any location around its periphery corresponds to the deformation of the leading surface of the flowable material at that location. The axial bearing depth of the completed die at any location is thus inversely proportional to the resistance to flow at that location, resulting in substantially uniform flow over the whole of the die aperture.

Abstract: A pair candidate list (73) is formed by selecting minutia pairs with reference to a minutia list (71) showing original position and direction data given for minutiae by principal coordinate systems preliminarily selected on a search and a file fingerprint and those relation data of the minutiae which are substantially independent of the coordinate systems. It is very likely that the pair candidate list shows coarse pairs because the coordinate systems may not yet be optimally matched to each other. One of the coordinate systems is transformed by those optimum amounts to provide transformed position and direction data which are decided by the original position and direction data of the minutia pairs of the pair candidate list. A pair list (86) is formed by precisely selecting minutiae from the pair candidate list with reference to the transformed position and direction data and the original position and direction data given by the other principal coordinate system and to the relation data. On forming the pair list, an additional minutia list (81) is preferably formed which shows the transformed position and direction data and the last-mentioned original position and direction data together with the relation data.

Abstract: @ Address calculation adders (130, 131) and a buffer storages (500,501) are each independently provided for each operand of an instruction requiring two or more operands. In the translation instruction processing, the address calculations and operand fetch operations on the first and second operands are substantially asynchronously conducted. Consequently, the overhead that takes place one every n second operand fetch operations can be removed by independently and asynchronously performing the address calculations and operand fetch operations by use of a plurality of address adders (130, 131). Moreover, the circuit for separating and obtaining a byte from the operand buffer can be dispensed with by adopting an operation procedure in which a byte of the first operand is fetched and is stored in temporary store means that supplies the address adder the data stored therein.

Abstract: A closure for a container comprises a top 11 with a depending skirt 12 having an internal screw thread. Where the skirt joins the top, the internal surface 15 of the skirt is conically flared in a direction away from the top, and a flexible resilient fin 18 extends from the underside of the top substantially parallel to the flared surface 15. The free end portion of the fin is thickened as by the provision of a broad rib 30 on the radially inner surface of the fin. When the closure is secured on to a container, the fin 18 becomes deformed outward and is sufficiently long to extend round the outer corner portion of the top of the container and is pressed into tight sealing engagement with said outer corner portion by the flared surface. The thickness of the free end portion of the fin causes it to resist expansion and to hug more closely to the corner portion of the top of the container. The radially inner surface of the fin may have annular grooves therein, for example of triangular shape, to provide a ribbed surface to improve the seal.

If there is an obstruction, no signal is generated, and the flip-flop is reset.
