Abstract: ABSTRACT OF THE DISCLOSURE     A roof construction having at least one roof slope is disclosed wherein at least four Z-purlins are laid across and secured to a number of rafters on the roof slope in a building and the roof deck is then secured on top of the Z-purlins.  Tendencies toward Z-purlin roll over failure are counter balanced when at least two of the Z-purlins on the roof slope are oriented to face down-wardly of the roof slope and at least two of the Z-purlins on the roof slope are oriented to face upwardly of the roof slope.  The downwardly and upwardly oriented Z-purlins may be arranged in pairs of adjacent Z-purlins, each pair com-prising one upwardly and one downwardly facing Z-purlin, or so that Z-purlins of one group face upwardly and Z-purlins of the other group face downwardly.  The Z-purlins are sta-bilized by means of stiffeners secured to the purlins at bearing points and by means of tie straps extending between adjacent purlins.

Abstract: METHOD AND APPARATUS FOR STARTING HIGH INTENSITY DISCHARGE LAMPS     Abstract of the Disclosure A high pressure sodium lamp, which includes a dis-charge tube enclosing xenon at pressures in excess of 300 torr, is reliably started by the combination of an igniter, a conductor wrapped around the discharge tube, and a switching circuit.  The igniter provides periodic pulses of 2500 to 4000 volts with a duration of at least one micro-second.  The switching circuit provides a high voltage pulse having an amplitude about equal to the amplitude of the periodic pulses and a duration much greater than the duration of the periodic pulses.  The conductor intensifies the electric field within the discharge tube.  A conven-tional lamp ballast provides ac power during starting and normal operation. 22,473

Abstract: ABSTRACT A regulated gas pressurization system for a beverage dispenser which includes a pressure regulator, cylinder valve, and quick coupling apparatus provided for securely connecting the valve and regulator for safe operation.  The regulator includes an adjustably biased diaphragm which operates a control valve which regulates the flow of gas from a gas storage cylinder to the beverage dispenser. The adjustment of the biasing force on the diaphragm determines the outlet pressure in the system.  A pivotable yoke which is part of the coupling apparatus is placed in a raised position so that the cylinder shut-off valve can be properly aligned with the regulator boss and lowered to a retaining position where a retaining screw can be turned inwardly to move the cylinder valve into rigid coupling position with the regulator.  Upon coupling, a poppet within the cylinder valve is opened automatically to allow gas to flow into the regulator.  This arrangement permits a short lateral sliding movement for installa-tion of a gas storage cylinder which allows a novice to change the cylinder safely and quickly in a confined space.  In another embodiment a diaphragm actuator directly contacts the slidable poppet within the cylinder shut-off valve to provide the gas flow controlling function in response to movement of the diaphragm.  A high pressure gas storage cylinder fill adapter is also provided which has a pivot-able yoke and probe for secure attachment to the cylinder valve during the pressure refilling of the cylinder. In order to provide additional protection for the high pressure gas storage cylinder, the pressure regulator is mounted on a vertical surface or cabinet wall at suf-ficient height to allow the gas cylinder to be supported by the regulator when connected to the system.  The regulator can be attached to the vertical surface by means of a bracket and releasable fasteners so that the re-gulator can be quickly removed, if desired.

Retained within the container between the front and rear walls is an at least partially light transmissive energy storage substance that experiences a liquid-solid phase change between 45° and 190°F. After being strategically positioned for exposure to solar radiation, the energy storage substance accumulates a substantial quantity of energy when changed to a liquid state by incident sunlight and subsequently releases that energy when again freezing.  In addition to sequentially and alternatively storing and releasing thermal energy, the container device transmits a pre-determined level of incident sunlight. Furthermore, the partially absorptive walls are heated by sunlight and function as efficient sources of heating for the retained energy storage substance.
