Title: Integrally formed linear light strip with light emitting diodes
Inventor: GUSTAFSON THOMAS L
IPC: F21K99/00
Filed: 1996-08-01
Abstract: An integral single piece extruded LED light strip and an associated process for producing such an LED light strip. The light strip includes first and second bus elements spaced apart from one another by a predetermined distance. The light strip also includes at least one light emitting diode (LED) connected between the bus elements that is illuminated when the first bus element conducts electricity provided from a power source.

Patent CA-2189813-A1 (CA)
Inventor: MAYNARD ALFRED CHARLES
IPC: F16K15/06
Filed: 1996-11-07
Abstract: To resist mechanical forces tending to unseat a fluid valve applied to seal against a high fluid pressure, a fluid valve assembly is equipped with a valve block that, in response to the high fluid pressure, causes a locking member to be forcibly wedged into clamping engagement with the stem of a valve, thereby securing the valve in its closed, seated position. When the high fluid pressure is relieved, the valve stem is unclamped, and the valve can then be readily lifted to an open position.

Title: Circuit arrangement for operating electric lamps, and an operating method for electric lamps
Inventor: RUDOLPH BERND
IPC: H05B41/292
Filed: 1997-03-25
Abstract: The circuit arrangement according to the invention has a self-oscillating inverter having at least two alternately switching transistors (Q1, Q2), a load circuit connected to the inverter output and designed as a resonant circuit (L1, C1), and terminals for at least one electric lamp (LP). According to the invention, the control junction of a transistor (T1) is arranged in the emitter line of one of the inverter transistors (Q2). Via the variable conductivity of this control junction, the effective emitter resistance of the inverter transistor (Q2) is continuously varied as a function of the voltage drop across one of the resonant circuit components (C1), and the clock frequency of the inverter (Q1, Q2) is thereby increased so far that because of the now stronger detuning with respect to the resonant frequency of the resonant circuit (C1, L1) a reduction in the no-load voltage in the load circuit is achieved.

Patent CA-2209670-A1 (CA)
Title: Technique for locking a laser diode to a passive optical cavity
Inventor: DIXON GEORGE J
IPC: G02F1/35
Filed: 1996-01-11
Abstract: A laser is disclosed whose resonant cavity includes a back facet of a semiconductor gain element as one mirror and a passive resonator as part of a second mirror. Appropriate optics are provided for a round-trip path within the resonant cavity that avoids double-passing the passive resonator so that intracavity losses are reduced and more power is fed back to the gain element, which is the active medium of the laser. By ensuring a high percentage feedback of the radiation to the semiconductor gain element, amplitude stable operation can be achieved while locking the frequency of the gain element to the passive resonator. By providing both frequency and amplitude stable operation, fluctuation of the circulating power in the passive resonator is minimized and, therefore, can be usefully employed for many applications. For example, non-linear crystals of well-known types can be placed within the passive resonator in order to achieve highly efficient second harmonic generation in a power regime and with frequency and amplitude stability that was heretofore unobtainable.
