Title: Method and system for subscription television billing   and acces
Inventor: BLOCK ROBERT S
IPC: H04N21/2543

Granted: 1984-03-06
Abstract: ABSTRACT OF THE DISCLOSURE          A subscription television system and method in which billing information regarding programs actually viewed by a subscriber of the system is accumulated over non-dedicated telephone lines.  A scrambled television program signal containing a block of television program material, a program identification code unique to the block of program material, and a program category rode, is broadcast.  The codes are preferably included in the vertical retrace inter-val of the video portion of the program signal and the trans-mitted program signal is selectively received at a sub-scriber station and selectively unscrambled to permit viewing of the block of program material being transmitted in response to subscriber action indicating acceptance for viewing of the block of program material.  The received program category code is compared with a locally generated category code to determine whether the program is acceptable for viewing.  The program identification code is detected and stored for subse-quent transmission in response to the subscriber action indi-cating acceptance for viewing of the received block of program material.      The program identification code stored at the sub-scriber station is selectively accessed from a remote location over telephone lines on other than a real time basis (e.g., a periodic basis) to thereby provide billing information at the remote location as to programs actually viewed by the subscriber.  The subscriber can thus be billed monthly or on some desired periodic basis for programs actually viewed during the preceding period.  The billing period can be varied from the remote location to provide a means to control the number of programs which a subscriber can receive.

Abstract: ABSTRACT OF THE DISCLOSURE           An electro-acoustical transmitter converts electrical signals which correspond to acoustical events into mechanical vibrations which are transmitted onto the skin.  The aim is to achieve a small vibrator which, insofar as possible, can be worn on the wrist, for instance, in the manner of a wristwatch.          To that end, a coil is employed into which a magnetic core, resiliently mounted relative thereto for instance by a diaphragm, projects as an armature.  The housing which carries both the diaphragm and the coil forms the magnetic return flux path.          Thus, a miniaturization of the vibrator on the desired order is achieved.  An inventive vibrator is particularly suited for facilitating speech training for the deaf.

Abstract: L'invention concerne la protection d'un jet de coulée de métal liquide, s'écoulant entre un réservoir supérieur et un réceptacle inférieur. Selon le procédé, on injecte au moins un gaz inerte liquéfié au-dessus et à proximité de la surface du métal liquide contenu dans le réceptable inférieur,et, simultanément, on injecte au moins un gaz inerte dans le métal liquide par le fond ou les parois dudit réceptacle. L'invention s'applique à la protection de jets de coulée de métaux, notamment entre poche et répartiteur, entre poche et lingotière, entre poche et poche, entre convertisseur (ou four) et poche. La divulgation décrit aussi une installation de transfert d'un métal liquide comportant un réservoir supérieur et un réceptacle inférieur munis d'un garnissage réfractaire interne, et un fourreau en matériau réfractaire ouvert à ses deux extrémités. L'ouverture supérieure du fourreau est située en-des-sous du débouché du réservoir supérieur; l'extrémité inférieure du fourreau est située à distance du fond du réceptacle inférieur tandis que l'extrémité supérieure du fourreau fait saillie largement au-dessus du bord du réceptacle inférieur. L'installation comporte des moyens d'injection d'un gaz inerte liquéfié à l'intérieur du fourreau et légèrement en-dessous de l'ouverture supérieure du fourreau et des moyens d'injection d'au moins un gaz inerte par le fond ou les parois du réceptacle inférieur. L'injection simultanée d'un jaz inerte dans le métal liquide par le fond ou les parois du réceptacle en-dessous de la zone d'impact du jet, participe à la formation d'une gaine protectrice ascendante et provoque un brassage du métal ce qui empêche les solidifications parasites, favorise une coalescence des inclusions et permet un effet de purge.

Title: Method for reading a text printed by a head equipped with a needle and  reading head using this method
Inventor: GASCUEL JEAN-PAUL
IPC: G06K15/10
Filed: 1983-04-06
Granted: 1987-01-13
Abstract: A readhead for reading text printed by a matrix printhead comprises an aligned array of side by side photodiodes (4). An optical system forms an image of a strip of the text support on the array. The image and the photodiode array are such that the image of a single printed dot of a character block normally covers an integer number of photodiodes. The array is periodically sequentially scanned to form an output signal which is digitized before being fed to a margin detector which determines margins above and below the character block. Signal blocks are stored after being analyzed by counting margin values and the number of "1" and "0" states. The process of the invention results in a signal which is effectively a reproduction of the signal originally used to print the character blocks.

Abstract: ABSTRACT CODED SURVEILLANCE SYSTEM HAVING     MAGNETOMECHANICAL MARKER A magnetic article surveillance system marker is adapted, when armed, to resonate at pre-selected frequencies provided by an incident magnetic field applied within an interrogation zone.  The marker is a plurality of elongated ductile strips of magnetostrictive ferromagnetic material each of the strips being disposed adjacent to a ferromagnetic element which, upon being magnetized, magnetically biases the strips and arms them to resonate at the preselected frequencies.  A substantial change in effective magnetic permeability of the marker at the preselected frequencies provides the marker with signal identity.

Abstract: Abstract of the Disclosure Process for the separation and purification of oxygen and nitrogen is disclosed which utilizes solutions of oxygen carriers to selectively absorb oxygen from a gaseous stream.  In the process, an oxygen carrier capable of reversibly binding molecular oxygen is dissolved in a solvent solution, which absorbs oxygen from an oxygen-containing gaseous feed stream such as atmospheric air and desorbs oxygen to a gaseous product stream, leaving nitro-gen as a byproduct.  The feed stream is maintained at a sufficiently high oxygen pressure to keep the oxygen carrier in its oxygenated form during absorption, while the product stream is maintained at a sufficiently low oxygen pressure to keep the carrier in its deoxygenated form during desorption.  In an alternate mode of opera-tion. the carrier solution is maintained at a sufficiently low temperature and high oxygen pressure to keep the oxy-gen carrier in its oxygenated form during absorption and at a sufficiently high temperature to keep the carrier in its deoxygenated form during desorption.  Under such con-ditions, exceptionally high oxygen concentrations on the order of 95% to 99% are obtained, as well as a long carrier lifetime in excess of 3 months, making the process commercially feasible.
