Title: Self-extinguishing gas probe starter for an electrodeless high intensity discharge lamp
Inventor: FARRALL GEORGE A
IPC: H05B41/24
Filed: 1992-11-12
Abstract: RD-21,333 SELF-EXTINGUISHING GAS PROBE STARTER FOR AN ELECTRODELESS HIGH     INTENSITY DISCHARGE LAMP                              Abstract The fill of a self-extinguishing gas probe starter for an electrodeless high intensity discharge lamp includes a starter fill component which has a relatively low vapor pressure and is substantially inert in the starter fill at ambient temperatures, but which component vaporizes and becomes electronegative as the temperature of the lamp increases, so that the starter fill component attaches electrons of the starting discharge in the gas probe starter and thereby extinguishes the starting discharge after initiation of the arc discharge in the arc tube.  As a result, the flow of currents between the gas probe starter and the arc tube, which would otherwise have a detrimental effect on the arc tube wall, is avoided.

Title: Apparatus and Method for Controlled Access to a Secured Location
Inventor: HEATH WILLIAM D JR
IPC: G07C9/00
Filed: 1992-11-18
Abstract: A system for authorizing access to a secured location, such as the vault of an automated teller machine (ATM) or the coin box of a pay telephone, without a key or combination for the secured location, and without requiring a fixed communication link extending to the location.  A service technician receives an encoded access message which identifies a present access code previously stored at the secured location, the personal identification number (PIN) of the technician, and the identification number of a portable terminal assigned to that technician.  The technician manually enters the encoded access message and the proper PIN into the terminal, where the identification number stored in the terminal and the manually-entered PIN are verified against the information encoded in the access message. If that information is authenticated, the technician then proceeds to the secured location and connects the portable terminal to a processor at that location. The encoded access message is transferred from the terminal to the secured location, where the access code previously stored at that location is compared with information contained in the encoded access message.  The technician must also re-enter the proper PIN at this time. Access is granted only if all information is verified by information in the encoded access message. If access is allowed, the access code at the secured location is replaced by a new access code contained in the encoded access message, and that new access code is stored for the next authorized access to the particular secured location.

Title: Method and device for determining an orientation related to a mobile system, particularly the line of sight in a helmet sighting
Inventor: ZIMMER PIERRE
IPC: G01B7/30
Filed: 1991-06-14
Abstract: A method for determining a line of sight from a sighting device mounted on a helmet provided with a sensor (2) with three orthogonal magnetic coils, in relation to a reference attached to an aircraft and having the form of a transmitter (1) having three orthogonal magnetic coils. According to the method, the cockpit is first magnetically mapped. For this purpose, sets of field measurements detected by the sensor for the fields successively produced by the transmitter's three coils for various known positions and attitudes of the sensor in the cockpit are established and memorized. Then, the cockpit is magnetically modelled on the basis of said measurements. In flight, the matrix of measurements, combined with a transmitter transmission cycle initiated when the pilot confirms a directional line of sight determined in relation to his helmet, allows the orientation of said line of sight in the aircraft reference to be accurately calculated on the basis of the model previously made. The method can be used for sighting from helicopters where the cockpit causes disturbances because of field reflexions from metal components.

Abstract: The present invention relates to a tamper-indicating tape for use with a container to indicate opening of the container. U.S  Patent No. 4,876,123 discloses a tamper-indicating tape for securing a first container part to a second container part to enclose an opening in the container. The tamper-indicating tape includes a light-transmissive monolayer film having opposing first and second major surfaces. In order to prepare the tamper-indicating tape, it is necessary to print first colored indicia and second colored indicia in such a manner so as to obscure the indicia in the absence of tampering. This requirement is difficult to fullfill, because perfect registration and good color matching between the ink of the indicia and the dye or pigment of the adhesive is required.  This invention provides a tamper-indicating tape (10) comprising a light transmissive monolayer film (12) having opposing first and second major surfaces (20, 24). On each surface is printed colored indicia (22, 26), preferably identical, such that the colored indicia on each surface obscure the colored indicia on the opposint surface when the film has not been split internally, but neither of the colored indicia obscure the other when the film has been split internally. The printing pattern of this invention dispenses with the requirement for accurate registration between first colored indicia and second colored indicia. The printing pattern further dispenses with the requirement for a color match between ink and adhesive.

Abstract: 2099491 9212404 PCTABS00014 The ellipsometer (1) and method involve directing polarized light for interaction with an optical system (2) under study at different angles of incidence from a single beam of light and detecting the light interacted with the optical system by reflection and/or transmission for each of a plurality of different angles of incidence. The simultaneous illumination of the optical system under study at a whole range of angles of incidence .alpha. from a single beam of light and the collection a large multiplicity of data from the different angles detected can be accomplished rapidly and easily and with accuracy without scanning and with only one ellipsometer. A lens (7) is used to focus the incoming light to provide the range of different angles of incidence .alpha.. The range of angles is at least one or two degrees and preferably thirty degrees or more. A second lens (8) refocuses the interacted light to a linear, multi-element detector array (6) which extends in the plane of the incidence. Each of the detector elements (9) detects a narrow range of angles of incidence within the relatively wider range of angles of incidence of the illuminating beam. If the incident illuminating rays are polychromatic and a wavelength dispersing element (10) acts on the reflected rays each detector element of a square array (11) detects a narrow range of wavelengths and angles of incidence.
