Title: Progressive power multifocal lens
Inventor: KITANI AKIRA
IPC: G02C7/06
Filed: 1996-04-18
Granted: 2008-11-04
Abstract: A progressive power multifocal lens designed by attaching importance to an intermediate vision and a near vision in such a manner as to ensure broad intermediate vision viewing portion and near vision viewing portion and to have a well-balanced viewing zone among the distance, near and middle portions, whereby a resultant image of an object is little varied or fluctuated, especially, in lateral directions. For example, a far vision power measuring position is located at a point which is 14 mm upwardly away from the geometrical center of the lens. Moreover, a near vision power measuring position is located at a point which is 17.5 mm downwardly away from the geometrical center and further is 2.5 mm inwardly to the nose of a wearer. Furthermore, an eye-point position, through which a visual line runs when the wearer looks to the front thereof, is located at the geometrical center.  Additionally, assuming that the far vision power measuring position is selected as a center and that a direction, in which a horizontal half-line extends right-wardly from the far vision power measuring position, is determined as a reference direction whose azimuth angle is 0, a nearly sectorial domain corresponding to azimuth angles of 30 to 150 degrees is used as a far viewing distinct vision zone in which the astigmatism is not more than 0.5 diopters irrespective of the value of an addition.  Further, a principal fixation line running through the far vision power measuring position, the eye-point position and the near vision power measuring position divides the surface of the lens into a nose-side part and an ear-side part in such a way that these parts are asymmetric in the horizontal or lateral direction.

In order to assist the user in retrieving the items of interest, a menu structure is transmitted as well. The menu structure renders it possible to access the database in various ways. Rather than including programme items (such as known form teletext systems), the transmitted menus refer to programme items. Where necessary, references can be made to programme information transmitted by different TV stations.

Title: A fraud control system for processing calls with an automatic number identification failure
Inventor: SHARPE THOMAS C
IPC: H04Q3/72
Filed: 1997-03-18
Granted: 2000-02-08
Abstract: A system for preventing fraudulent calling activity in a telecommunications network when an Automatic Number Identification failure (ANIF) occurs at a switch attempting to process a call within the network. When an ANIFoccurs, an operator obtains information equivalent to an Automatic Number Identification (ANI) from the calling party and the system determines whether the call is of a type that would not have been restricted had the ANIF not occurred. If the call would not otherwise have been restricted had the ANIF not occurred, the system automatically assigns a blanket billing restriction to the call which only allows specific call types (such as what are deemed the safer alternate billing methods of collect or credit card) and blocks other restricted call types.

Abstract: Electropneumatic brake control valve for control of brakes on a railway vehicle. It has a supply valve and release valve moved by a common displaceable actuator. The supply valve connects an air supply passage to a delivery passage and the release valve connects the delivery passage to an exhaust. The delivery passage is for supplying air to a brake shoe application device. The invention has a feedback space having pressure connection to the delivery passage. A portion of the common displaceable actuator is located within the feedback space, as is a positioner for the common displaceable actuator. The positioner has at least three force and displacement communication portions.      The first communicates a first force and a first displacement with the common displaceable actuator. The invention has a pressure defining member which defines pressure by its position.      It communicates a second force and a second displacement with the second one of the force and displacement communication portions.      The invention has a pressure regulator which has a regulating member communicating a third force and a third displacement with the third one of the force and displacement communication portions. The regulator moves in accordance with a comparison between the air pressure in the feedback space and a force exerting device. The force exerted by the force exerting device is dependent on the third displacement. The invention also has apparatus for positioning the pressure defining member, this apparatus controlled by electrical signals from a brake control system of the railway vehicle.

Abstract: A method of measuring the conductivity of earth formations penetrated by a wellbore. The method comprises selectively passing an alternating current through transmitter coils inserted into the wellbore. Each of the transmitter coils has a magnetic moment direction different from the magnetic moment direction of the other ones of the transmitter coils. The alternating current includes a first and a second frequency. The amplitude at the first frequency has a predetermined relationship to the amplitude at the second frequency. The relationship corresponds to the first and the second frequencies. The method includes selectively receiving voltages induced in a receiver coil having a sensitive direction substantially parallel to the axis of the corresponding transmitter coil through which the alternating current is passed. A difference in magnitudes between a component of the received voltage at the first frequency and a component of the voltage at the second frequency is measured, and conductivity is calculated from the difference in magnitudes of the components of the received voltage at the two frequencies.  In a preferred embodiment, the step of measuring the difference in magnitudes between the voltage components at the two frequencies includes extracting digital signal samples of the received voltage at predetermined times with respect to a cycle of the transmitter current at the first frequency.

Title: Film-enrobed, unitary-core medicament and the like
Inventor: DIETEL GREGORY LOUIS
IPC: A61J3/10
Filed: 1989-11-21
Granted: 1999-08-17
Abstract: A medicine tablet is described as a new article of manufacture. The tablet is enrobed in a gelatin coating formed by application of respective layers of elastic gelatin film to opposite sides of the tablet. The applied gelatin layers conform tightly to the tablet surface, bond securely to the tablet, and are sealed together in essentially edge-to-edge manner at a seal line which extends around the tablet at a desired place on the tablet. The gelatin layers can be colored differently from the tablet anddifferently from each other. A range of formulations are described for film which can be peelable from a tablet or other product core, and for films which bond to the core. A presently preferred formulation for producing tablets having a bonded tamper-evident coating comprises a water-based gelatin preparation having about 45 % gelatin and about 9% plasticizer (glycerin and/or sorbitol) by weight. Method and apparatus for producing such new products are also described. Product cores can be dispensed on a self-timed basis into essentially simultaneous contact with two enrobing films which are supported on locally recessed coactingrotary dies. The cores contact the films adjacent a nip between the dies at places on the films which overlie die recesses which are oversize relative to the cores. The films deform around each core and are sealed by the dies to each other before the dies coact to cut the enrobed cores from the films. A core feeding mechanism can include an alignment device which causes the cores to have a desired orientation as they are handled by the dies.

Abstract: A method of avoiding phase discontinuities between adjacent sections of a long Bragg grating written section-by-section in an optical fibre uses masks with alignment parts additional to their writing parts. Each alignment part is a replica of a portion of the writing part of the adjacent mask. The writing of the Bragg grating produces an associated absorption grating and so, for light directed in series through the alignment part of the mask and the already-written previous section of the grating, transmission is at a maximum when the mask is moved into exact registry. Fine adjustment of mask position is made to find this condition before writing with this mask is commenced.
