Abstract: A circuit for starting and operating a discharge lamp,  such  as  a  compact  fluorescent  lamp,  at high frequency  from  an  60  Hz  AC  supply.  The  circuit includes a power supply for generating a DC voltage coupled to  a pair of AC  input  terminals.   A DC/AC converter  includes  an.  oscillator  having  a  pair  of semiconductor switches coupled in parallel with the DC power supply.   An  oscillator  starting  circuit  is coupled  to  one  of  the  semiconductor  switches  and includes  a  series  circuit  comprising  a  resistor, capacitor  and  threshold  element.   The  input of the oscillator starting circuit is coupled to one of the AC  input  terminals  so  as  to  prevent  a  momentary flicker in the lamp after the AC supply is removed and the lamp has extinguished.  In accordance with another aspect  of  the  invention,  the  oscillator includes fusible circuit elements which render the oscillator inoperable upon failure of the lamp due to depletion of  emissive  material  on  at  least  one  of  the  lamp electrodes.

Abstract: A fiber optic sensor coil is wound from a length of optical fiber with the mid-point of the optical fiber at the mid-point of the innermost layer of the coil and subsequent layers of the coil each have alternating turns of the two sections of the fiber emanating from the mid-point. The layers of alternating turns are formed by first winding a portion of one segment in such a fashion that adjacent turns are spaced apart by a distance equivalent to the diameter of the optical fiber. The layer is completed by winding a portion of the other segment such that the turns of the other segment are disposed between adjacent turns of the one segment. The number of turns in adjacent layers are unequal such that the turns of a next layer are arranged in grooves formed between two adjacent turns of optical fiber in the previous layer.

Title: Water conservation system
Inventor: LINN MARK STEPHEN
IPC: F24D17/00
Filed: 1996-08-01
Abstract: Domestic water conservation piping system has thermostatically controlled diverter valve in series with water heater and shower head and/or a hot water shunt tube extending from the hot water heater to the fixture hot water supply in parallel with the thermostat piping.  When low temperature water is detected in the "hot water" line, the thermostatically controlled diverter valve diverts the low temperature water to a secondary water closet which stores the water at atmospheric pressure.  The secondary water closet provides make-up water to a toilet's primary water closet.  When the thermostatically controlled diverter valve senses high temperature water, the line to the secondary water closed is closed, and the hot water is diverted to the shower head.

Title: Improvements in packages for a food tray
IPC: B65D5/42
Filed: 1997-09-10
Abstract: The present invention is a food package comprising, in combination, a tray, a collar, and an anchor to resist slideable displacement of the collar relative to the tray. The tray has a plurality of open top food compartments, and, in plan view, is substantially rectangular with a top planar surface defining perimeter edges about the tray and borders between top openings of the compartments. Each compartment has bottom and side surfaces, the bottom surfaces lying substantially in a bottom plane parallel to the top surface of the tray, the sides of adjacent compartments being separated by predetermined spaces. The collar surrounds the tray over the top surface, about a first perimeter edge of the top surface, covering the sides and bottom surfaces of at least a portion of two adjacent compartments and about a second perimeter edge opposite to the first perimeter edge. The anchor is pressed from the collar into a space between the sides of two adjacent compartments to resist slideable displacement of the collar relative to the tray. In a preferred embodiment of this invention the collar also has an integral stand to support the package upright on it's edge with the top surface in a substantially vertical plane. For example, in an embodiment where the collar begins as a strip which is wrapped about the tray, the strip ends may overlap at the joint with an outside end extending from the joint to form a tab. The joint may be placed close to the perimeter of the bottom plane so that the extending tab can act with the corresponding edge of the top surface to support the package upright on its edge.
