Title: Method of hot restarting electrodeless hid lamps
Inventor: GREGOR PHILIP D
IPC: H05B41/24
Filed: 1991-11-26
Abstract: The present invention describes an apparatus and method for shutting off an electrodeless lamp such that it can be restarted instantaneously at any time. The method involves reducing the applied microwave power in a con-trolled way the moment the lamp is turned off. The reduc-tion of power is accomplished by modulating the microwave power with an ever decreasing duty factor or a decrease of analog power. This reduction in power results continually in reduced light output and lamp cooling while maintaining partial ionization of the lamp fill. Circuitry to accomplish this is also presented.

Title: Connection of two sectional bars, sectional bars for a support system and support system for sanitary apparatus, as well as a process for constructing such a support system
Inventor: WARKUS CLEMENS
IPC: F16B7/10
Filed: 1991-12-12
Abstract: The connection has a connection piece (1), which has two displaceable wedges (4, 13) in a bearing housing (8). These wedges (4, 13) can be displaced in the bearing housing (8) independently of one another by means of a guide bearing (15, 15). In the working position, the wedge (4) extends into a dovetailed longitudinal groove (20) of a sectional bar (2). The front side (5) of the wedge (4) is profiled and engages a correspondingly profiled wall (22) of the sectional bar (2) in a positive-locking manner. The wedge (4) spreads two clamping tongues of the bearing housing (8) against the flanks of the longitudinal groove (20).      By pivoting the guide bearing (15), the wedge (4) can be retracted, and the connection can be separated. A second wedge (13) is inserted axially into the interior space of a second profiled piece (3). This wedge (13) spreads two brackets (11) of the bearing housing (8). Both sectional bars (2, 3) have the same design and may be cut off to any desired length. No further processing of the sectional bars (2, 3) is necessary.

Patent CA-2059025-A1 (CA)
Inventor: SPAHLINGER GUENTER
IPC: G01C19/72
Filed: 1992-01-08
Abstract: The subject of the invention is a fibre-optic rate of rotation sensor in open loop configuration, in which sensor bias errors which arise on account of coupling in of disturbing signals into the input of a demodulator (SYNCD) are suppressed by the use of a demodulation signal which is statistically independent of all signal sources which may be considered as a cause of           ~ disturbing signals. To this end, a modulation signal generator (MG) is provided, which includes a random number generator from which two signals (b0, b1) are derived on the one hand for a statiscally alternating bias for the activation of optimal working points with positive or negative gradient on the interferometer characteristic and an appropriately matched demodulation signal (d) is derived on the other hand, which demodulation signal, after transit time correction (T0), acts upon the synchronous input of the synchronous demodulator (SYNCD).

Patent CA-2065407-A1 (CA)
Inventor: HAYES THOMAS H
IPC: B65D41/34
Filed: 1990-08-22
Abstract: A closure for a container has a tamper indicating band with a band retainer in the form of an apertured flap or hoop which is hinged to the lower edge of the band. A series of windows open through the retainer, extending toward but not to its distal edge. As the retainer is turned inside out from its as-molded position to its use position, its distal and/or hinged edges deform to relieve compression and permit the retainer to be inverted by direct downward pushing force. As a result of the deformation, the retainer in its use position may, depending on the number and size of windows, have an advantageous polygonal peripheral shape rather than a circular shape.

IPC: A01N63/00
Filed: 1990-10-26
Abstract: A method is disclosed for protecting a growing crop from pathogens comprising applying to the growing crop and to any pathogen present thereon a compound capable of generating an active oligomer elicitor in the crop or the pathogen. The compound is applied with a penetrating agent which aids in the entry of the compound into the cuticle layer of the growing crop or the pathogen. The elicitor is generated in the crop or the pathogen in an amount effective to elicit production in the crop of an anti-pathogenic agent. When the elicitor is generated in a pathogen present on the harvested crop, the elicitor is generated in sufficient amount to transfer into the crop, which transfer may be aided by the presence of said penetrating agent, in order to produce the desired phytoalexins in the harvested crop. Also disclosed is a composition comprising the above compound and a penetrating agent for the compound as well as a growing crop treated with the above composition.

Abstract: W. E. 56,441 ABSTRACT OF THE DISCLOSURE     A  TFEL  edge  emitter  structure  has  a  bottom substrate layer, a lower common electrode layer applied over  the  bottom  substrate  layer  an  upper  control electrode  layer,  and  a  middle  EL  light-energy generating  stack disposed  between  the  lower  common electrode and the upper control electrode layers.  The middle EL stack includes a lower dielectric layer, an upper  dielectric  layer,  and  a  middle  light-energy generating layer.  The lower dielectric layer overlies the lower common electrode layer and bottom substrate layer.   The middle light-energy generating layer is deposited over the lower dielectric layer.  The upper dielectric layer is deposited over the middle light-energy generating layer.   A light emitting face on a front edge of the EL stack is disposed at an angle relative to a street on the front edge portion of the substrate layer that is greater than ninety degrees. The angle selected should be sufficiently greater than ninety degrees relative to the substrate layer street so that a divergent zone of light emitted by the face is not obstructed by the street.  A focusing lens is located at a position spaced in front of the inclined light emitting face of the TFEL edge emitter structure where the lens will intercept and intensify a zone of light emerging from the inclined face.  A central axis of  the  focussing  lens  extends perpendicular to  the respective light emitting face.

Title: Adjustable resonator arrangement
Inventor: ALA-KOJOLA JOUNI
IPC: H01P7/04
Filed: 1992-06-15
Abstract: ABSTRACT             ADJUSTABLE RESONATOR ARRANGEMENT     An adjustable resonator arrangement comprises a main resonator (T1) and a secondary resonator (T2) reactively coupled thereto.  The secondary resonator includes a switching element (S), e.g. a varactor, having at least two states.  When the switching element is in a first state the secondary resonator behaves as a half-wave resonator having a resonant frequency fo substantially different to the resonant frequency f of the main resonator.  Consequently the secondary resonator has no appreciable affect on the resonant frequency of the main resonator.  However, when the switching element is in a second state, the secondary resonator behaves as a quarter-wave resonator having a resonant frequency 2*fo which is closer to the inherent frequency f of the main resonator and sufficiently close to cause a shift .DELTA.f in the effective frequency of the main resonator.  Suitably the main resonator is realized as a dielectric resonator and the secondary resonator is realized as a strip line resonator in the form of a conductive strip provided on a side face of the dielectric block from which the main resonator is formed.
