Abstract: ABSTRACT OF THE DISCLOSURE           The heat of welding substantially impairs the strength of aluminum structural members.  Applicant overcomes this problem by welding to one or more sacrificial flanges integrally formed with such a member.  With the welding restricted to the flange, the weakening effect of the welding operation is thereby isolated from the load-bearing portion of the structural member.  Load-bearing shoring frames made from aluminum tubing are used to illustrate this invention.  The frame legs are each preferably extruded with a pair of spaced parallel sacrificial flanges.  The horizontal bracing extending between the legs are welded to the respective pairs of sacrificial flanges on each respective leg.  The welding is sufficiently distant from the load-bearing portion of the leg so that the heat of welding dissipates sufficiently before the leg proper is affected thereby.

Abstract: INDUCED DRAFT COOLING TOWER                Abstract of the Disclosure An induced draft cooling tower includes a unitary, seamless shell fabricated from a rust-free, plastics material.          The cooling tower operates on the counterflow principle whereby a fluid to be cooled is directed downwardly through a block of cellular packing disposed within the tower, while cooling air is drawn upwardly through the cellular packing and is exhausted at the top of the tower.  A fan is mounted atop the tower for purposes of drawing air through the tower.  The shell includes a polygonal lower portion for easier formation of air inlets and for attachment of plumbing fixtures.  The shell is fabricated from an inexpensive, relatively weak plastics material; however, due to the con-figuration of the shell, the tower possesses favorable strength characteristics and avoids the need for supple-mentary structural supports.

Abstract: Abstract:          ELECTRICALLY CONTROLLED UNIT INJECTOR      An electrically controlled unit injector for a diesel engine wherein both timing of injection and the quantity  of  fuel  premetered  into  the  injector  are controlled by a single solenoid.   The control  of  the timing portion of the cycle is accomplished by a timing port of the valve which, when open, permits fuel to flow into the timing chamber  and,  when closed,  operates against high pressure to shut off the flow of fuel from the timing chamber.  The metering function is initiated by the upward travel of a metering plunger in response to the upward travel of a pumping plunger while the timing port of the valve is closed.  Metering is terminated by a metering port of the valve which shuts off the supply of fuel to the metering chamber.   The timing and metering ports of the valve are controlled by the single solenoid.          Metering quantity control may be of the pressure-time or volumetric metering type.

Abstract: ABSTRACT OF DISCLOSURE     An   apparatus   is   disclosed   for   use   in spectroscopically analyzing properties of a plurality of test samples.  The apparatus includes a support member for stationarily  supporting  a plurality of test cells con-taining test samples to be analyzed and suitable devices for  directing  a  beam of  radiation  successively at the test cells and for then receiving output radiation from the  test  cells.  The  radiation  directing  and  detector devices are mounted in fixed relationship to one another, and arranged with respect to the support member so that when the beam of radiation from the radiation directing device  is  directed  onto  one  of  the  test  cells,  the radiation detector will receive output radiation from the same cell.  The radiation directing and detector devices are moved as a unit relative to the stationary test cells in  a  manner  so  that  the  beam  of  radiation  from the directing   device   is   directed   successively   at   the plurality of test cells,  whereby the radiation detector device  will  then  receive  successively output  radiation from  the  plurality  of  test  cells.  In  this  manner, analysis of the properties of a plurality of test samples may be quickly and efficiently made.  Further,  the fact that the test cells are stationarily supported and the radiation  directing  and  detecting  devices  are  moved relative thereto is most advantageous in connection with spectroscopic analysis of flow through fluid test samples in which the sample fluid to be analyzed is continuously introduced  into  and  withdrawn  from  the  stationarily supported test cells.
