Abstract: A photographic processing apparatus capable of printing films having different widths.  An exposure unit for printing film images on photographic paper has a negative mask to guide the movement of the films.  The negative mask is provided with a plurality of film guide paths which correspond to widths of the films.  A transfer unit is provided to move the negative mask in a direction perpendicular to the feed direction of the film.  Along the film feed path toward the negative mask are provided sensors to detect the film size.  Printing is carried out in such a manner that after the film size has been detected by the sensors, the transfer unit is controlled by the signal from the sensors to bring one of the film guide paths which corresponds to the film size into alignment with the exposure axis.

Granted: 1999-04-20
Abstract: A compact core and ejector assembly includes an elongate core terminating in a male mold component and including a cylindrical shoulder which supports the top plate of an associated core support frame.  The shoulder includes opposing, longitudinally-extending slots which receive jaw elements, which are pivotally mounted on a reciprocating knock out plate, and therefore guide the jaw elements during the ejection procedure.  The top plate, knock out plate and core plate are cut away so that rows of cores may be arranged in a densely packed configuration.  In a preferred embodiment, the lateral sides of the top, knock out and core plates have a cut away or sinusoidal shape so that abutting rows fit in an overlapping relationship.

Abstract: L'invention concerne un appareil et un procédé de validation des éléments d'une boucle à verrouillage de phase (BVP) (300). La BVP (300) comprend une pluralité d'éléments (202, 203, 204, 205). Chaque élément produit un signal de sortie (207, 208, 209, 116 ou 117). Chaque élément possède un temps de réponse (t3-t2) défini par la différence de temps entre un premier temps t2, auquel l'élément est validé et un deuxième temps t3, se produisant après le premier temps t2, auquel le signal de sortie de l'élément atteint un état de régime permanent. Un oscillateur commandé en tension (204) appartenant à la pluralité d'éléments, ayant un premier temps de réponse t3-t2, est validé au premier temps t2 réagissant à un premier signal de commande (302). Un diviseur de boucle (205) appartenant à la pluralité d'éléments, ayant un deuxième temps de réponse inférieur au premier temps de réponse (t3-t2), est activé en réponse au premier temps de réponse t3-t2 et au deuxième signal de commande (303).

Title: Method and apparatus for eliminating television commercial messages
Inventor: IGGULDEN JERRY
IPC: H04N7/00
Filed: 1994-01-06
Granted: 2004-06-29
Abstract: During recording of a TV signal on a VCR, data is accumulated representing time of occurrence and duration of events in the television signal, and is stored in memory (42). A time code generator (50) generates time codes which are written on the tape as it is recorded. After recording, the stored data is analyzed to classify the content of the TV signal and a playback map is constructed and stored in memory (64). During playback, the map is retrieved and stored timing data are compared with timing reference data read from the tape. The VCR is fast forwarded when the tape reaches the beginning of a portion of the video signal that has been classified for elimination during playback. The VCR is put in the "play" mode when me tape reaches the end of that portion of the video signal. Since the entire TV signal is recorded, all of the signal may be viewed, even if parts have been misclassified.

Abstract: A rotary cone rock bit has bearing inserts pressed into the side of the shirttail portion of the rock bit body for stabilizing the rock bit during drilling. Such a rock bit has a steel bit body with a threaded upper pin for connection to a drill string. Cutter cones are mounted on lower leg portions of the rock bit body. The rock bit body gradually decreases in diameter from the gage diameter adjacent the lower tips of the shirttails adjacent to the cones to a smaller diameter shoulder the pin end of the body. The lowermost bearing insert protrudes laterally from the gradually decreasing diameter part of the bit body approximately half way between the lower tip of the shirttail and the shoulder at the upper end of the shirttail. The outer ends of the bearing inserts are rounded and substantially at the gage diameter of the bit for bearing on the wall of the borehole being drilled without appreciably reaming the borehole. The bearing inserts may have a layer of polycrystalline diamond on the protruding ends for minimizing wear. The protruding bearing inserts stabilize the bit without disrupting fluid flow around the bit.

Title: Implied interleaving, a family of systematic interleavers and deinterleavers
Inventor: AMRANY DANIEL
IPC: H04L27/00
Filed: 1996-04-22
Granted: 2000-03-07
Abstract: Apparatus that realizes a substantial advantage by employing implied interleaving to create a systematic interleaver, that can result in a superior block error rate compared to the current data interleaving techniques in which uncorrected error bursts are distributed by the deinterleaver. The disclosed principles lead to a embodiments that essentially eliminate transmitter memory regardless of the interleaving approachemployed. By way of example, block interleaving (regular or random), convolutional interleaving (regular and random) and product interleaving approaches are described. In implied interleaving, all incoming data is treated as if it is pre-interleaved and transmitted directly to its destination without alteration to its sequence, and essentially without delay. Concurrently with the transmission of the data, the data is applied to apparatus that treats the data as if it had been interleaved in accordance with a selected interleaving approach and, in accordance with such treatment, redundant symbols are generated and inserted into the transmitted data stream. At the receiver, the incoming data is delayed, corrected, and the information symbols in the incoming data are delivered to the user, corrected as necessary, in the same order as the information symbols arrived at the receiver.

Abstract: The convertor employs pairs of single-phase rectifiers (1,6) with forced switching which are fed from secondary windings (3,5) of a main traction transformer (T). Energy from a DC network passing through the transformer is recovered from one secondary winding (5) by the rectifier (6) working in voltage-boosting mode. The other rectifiers function synchronously as voltage invertors with the primary winding (7) of the transformer open-circuited. The output DC voltage (S) is maintained at a value slightly greater than half of the input voltage (E).
