Abstract: ABSTRACT A compact fuel cell stack in which a plurality of fuel cells are arranged in a stack between end plates. Resilient means such as springs are connected between the end plates, imposing on the end plates a force which urges the  end  plates  together  to  apply  a  predetermined compressive  loading  to  the  cells.   The  springs  are entirely disposed in the space between the end plates and do not extend exteriorly above or below the end plates, thereby reducing the overall stack height and weight as compared with conventional  structures.   force  adjusting means to adjust the force imposed by the resilient means are preferably included.

A furnace body having a refractory lined cavity which has a top opening is pivotally mounted on a support frame to allow tipping thereof.          A cover having a first opening to receive a gas burner and a second multi-purpose opening therein is rigidly attached to the body.  A gas burner attached to the cover provides a downwardly directed oxidizing flame into the cavity to oxidize iron which is added to the cavity and other impurities in the precious metal containing material.  A flux is provide to provide a thoroughly liquid mixture and after heating, the molten mass is poured through the multi-purpose cover opening into a mold.  As the mold cools, a dore button of precious metal settles to the bottom of the mold and slag containing impurities forms on the top.

Abstract: TRANSMISSION LINE CONTROL SYSTEM          Abstract of the Disclosure:      The present invention provides a transmission line control system capable of disconnecting and reconnecting a terminal communication apparatus from and to a main trans-mission line reliably and quickly at such occasions as a fault in the line, correction of the fault, cutting off and turning on of a power source.  The control system according to the present invention includes, for each terminal commu-nication apparatus, two subsidiary communication lines, a by-pass, two signal monitoring devices, and four change-over switches.  Each signal monitoring device monitors data signal passing through the subsidiary transmission lines and controls the switching operation of the change-over switches so that, upon occurrence of a line fault or a disconnection of the power source, only the terminal communication appara-tus related to the trouble is disconnected from the main transmission line and that, upon correction of the line fault or turning on of the power source, said terminal communication apparatus is reconnected with the main trans-mission line.  In order to perform such control operation properly, constants deciding the lengths of time of opera-tion of the signal monitoring devices are determined to satisfy given inequalities.

Abstract: Abstract of Disclosure A fluid-system control valve apparatus having an adjustable valve assembly between base passages and action passages.  The valve assembly comprises a pair of interfaced valve members individually rotatable and normally in neutral relationship.  One is a driver and the other a follower.  Rotation of the driver alters the neutral relationship and forms fluid passages through the valve assembly.  A reactive damming cavity is fed by a metered portion of fluid passing through the valve assembly and effects subsequent followup rotation by the follower, thus reforming the aforesaid neutral relationship.  Steering systems for vehicles comprise the control valve apparatus, a turntable for wheels, a hydraulic cylinder for turning the turntable, and conduits between the valve apparatus and hydraulic cylinder.

Abstract: IMPROVED HIGH SPEED PROCESS FOR FORMING        FULLY DRAWN POLYESTER YARN Abstract of the Disclosure An improved process is provided for producing fully drawn multifilamentary polyethylene terephthalate yarn via a high speed melt spinning process wherein the multifilamentary material following solidification is passed through a heated conditioning zone wherein substantial crystallization takes place.  Such multifilamentary product is withdrawn from the conditioning zone at a speed in excess of 8000 feet per minute and a conventional drawing step is not required.  In accordance with the concept of the present invention it surprisingly has been found that the uniformity of the multifilamentary product is enhanced by the inclusion of a minor substantially uniformly dispersed concentra-tion of particulate silicon dioxide (e.g. fumed silica) in the molten polyethylene terephthalate polymer prior to extrusion and such subsequent processing.  In a particularly preferred embodiment the particulate silicon dioxide is substantially uniformly dispersed within the polyethylene terephthalate as a result of its prior admixture with the reactants which were poly-merized to form the polyethylene terephthalate.

Abstract: Abstract of the Disclosure The disclosure relates to method and tools for making shells used in the manufacture of can ends.  A first set of tools makes blank pre-forms having a substantially flat central panel and an upward-extending chuckwall about the edge of the panel.  The junction area between the panel and the chuckwall has a relatively large radius of curvature at this time.  A second set of tools forms on the blanks a lip extending outward from the upper end of the chuckwall and generally parallel to said panel; then the panel and the chuckwall are separately gripped, followed by relative movement between the panel and the chuckwall while wrapping the junction area around a forming punch to form a panel wall in the junction area extending upward from the inner part of the chuckwall. Then the lip is formed into a curl edge section which ends in an inner curl diameter that is round and concentric with the chuckwall.  Methods and apparatus are disclosed for (a) separating the pre-forms at the first tools and then transferring them individually to the second tools, or (b) partially separating the pre-forms at the first tools and using the advancing sheet metal stock to carry the pre-forms to the second tools.  Also disclosed are various tool layout modifications for use in different types of single acting or double acting reciprocating presses.

On movement of the frame parts backwards and for-wards, an individual sheet is removed from one end of the pile and added to the other end of the pile.  A separating means (20/266) separates the individual sheet (188) from the pile, and a feeding means (460) feeds sheets to the separating means.          Retaining means (460/20) holds the individual sheet in the first frame part and the remainder of the pile in the other frame part, and a guide means for guides the separated individual sheet for the purpose of returning it to the other end of the remainder of the pile.  The feeding means and the retaining means are formed by a transporter (460) engaging the rear edge (seen in the feeding direction) of the sheet to be separated and a pressure arrangement (476) is provided on the side of the pile remote from the transporter.  The pressure arrangement holds the sheet being separated in engagement with the transporter until the latter enters the separating means, and the guide means is controlled by the movement of the frame parts and permits the introduction of the individual sheet between the pressure arrangement and the pile.
