Abstract: APPARATUS FOR BENDING AND TEMPERING GLASS                  ABSTRACT         Apparatus (20) for sag bending and tempering sheet glass includes  a vacuum holder (92) that is positioned within a furnace heating chamber (50) above a conveyor (66). The vacuum holder has a downwardly facing surface (94) with spaced openings (106,108) in which a vacuum is drawn to receive a glass sheet from the conveyor and support the sheet above the conveyor. The holder surface is disclosed as being both planar and curved and as having a porous cover (104) of ceramic fibers so as to distribute the vacuum and prevent marring of the glass as it is supported.  A carrier mold 164 is moved under the supported glass and the vacuum is then terminated so the glass drops onto the ring and sag bends under the bias of gravity in a manner that allows thin glass to be accurately bent.  Subsequently an actuator (192,194) moves the carrier mold to a quench unit (24) to temper the bent glass.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention concerns an arrangement for measuring the ratio between a number of events occurring after each other in a first series of events and a number of events in a second series of events, each series activating a pulse generator included in the arrangement.  The arrangement further comprises a counter, which is stepped forward by the pulses generated by said pulse generator controlled by said first series of events.  A multiplying arrangement receives the counter value of said counter and multiplies this value by a factor m where m indicates a selected part of the received counter content.  The multiplying arrangement receives on a control input, a pulse from said pulse generator controlled by said second series of events.  When the arrangement receives said pulse it feeds a signal to a subtracting input of the counter, which signal reduces the counter content by a number of steps corresponding to the multiplication result, so that the counter content varies between two limit values.  An indicating unit is arranged for indicating the difference between said two limits thus showing the quotient between the numberof events of said two series of events.

Abstract: ABSTRACT     A fluid shear coupling is disclosed herein which comprises a coupling disc received within a housing.  The coupling disc and housing are mounted for coaxial rotation, and the coupling disc is connectable to a drive pulley assembly for driving the coupling disc in rotation.  The coupling disc includes a pair of annular flanges extending axially in opposite directions from the periphery of the disc.  The flanges define inside and outside working surfaces with the inside and outside working surfaces including helical grooves for moving a fluid received against those surfaces in a predetermined direction.  The housing includes working portions closely conforming to the working surfaces of the flanges.  A fluid reservoir is defined by the housing and is operable to move a working fluid into the space between the flanges and the working portions of the housing to provide variable coupling of the housing with the coupling disc.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to controlled atmosphere heat treating furnaces and particularly to furnaces for bright annealing of copper or its alloys.  A new concept is proposed for conserving energy uses by first having a separate atmosphere producing system that fires constantly, independent of the temperature control and secondly having a cooling system that only extracts the excess heat produced by the combustion for atmos-phere.   In this way the furnace may be maintained at the desired operating temperatures regardless of variation of the work load, yet all of the heat generated by the atmosphere producing device is released within the furnace thereby eliminating unnecessary heat losses.

Abstract: Abstract Acid or base species concentrations in aqueous sample solutions are determined in the presence of interfering ionic salts.  Concentration of acid or base species is determined by a flow injection method combined with differential con-ductivity detection and ion-exchange derivatization wherein the acid or base species is derivatized to water or absorbed and blended indistinguishably into an aqueous carrier phase, and wherein the inter-fering salt(s) is derivatized in whole or in part to a distinguishable hydroxide or acid derivative(s). In a detector read-out, the calibrated peak of a con-ductimeteric response of the salt derivative(s) is compared to the peak of a conductimetric response of the sample solution and the response differential is displayed and used to determine the acid or base species concentration.  The salt(s) concentration is determined since it is proportional to the first men-tioned peak. The technique has utility with respect to acids and bases and most advantageously to strong and moderately strong acids and bases of PKa and PKb value, respectively, of less than 2.

The process comprises extruding a hollow molten stream formed from axially extending segments of dissimilar polymers arranged alternately in side-by-side adhering relationship to form the hollow molten stream.  The stream is then quenched under conditions sufficient to form a filament and the filament is then withdrawn from the stream at a predetermined spinning speed.          The polymers, the spinning speed and the quenching conditions are sufficient to form a filament characterized in that sub-filaments split from the filament possess substantial latent torqueless helical crimp.  A hollow conjugate filament being substantially free of crimp with sub-filaments possessing substantial latent torqueless helical crimp is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         Methods and apparatus are disclosed for forming a precision three-dimensional surface to plastic clad optical fibers.  The plastic cladding of a fiber end is deformed to conform to the geometry of the interstice formed between at least three tangential and parallel cylinders.          The cylinders are dimensioned such that the clad wire has a greater diameter than the largest circle which can be drawn in the interstice between the cylinders when they are in tangential contact so that, with the cylinder initially apart and the clad fiber end inserted in the inter-stice, the cylinders can be closed together to deform the plastic cladding. The precision three-dimensional fiber end enables accurate low loss coupling between the fibers to be achieved through the accurate reference planes presented.

Abstract: OFF-LOADER     ABSTRACT OF THE DISCLOSURE           An expandable modular housing is adjustably positioned with its open entrance side adjacent the output end of a conveyor feeding one or more lanes of parts.  Affixed to the under-surface of the top of the housing are a pair of normally open jaws aligned with each lane.  Each pair of jaws is movable along guide rails, in the direction of conveyor movement, between a first position where the jaws are opened and situated to receive a part from the conveyor, the presence of which is sensed to close the jaws and cause movement of the jaws through a second position, wherein the jaws are caused to open to release the part,to a third position, spaced from the second position, along the same direction.  Below the path of movement of each pair of jaws is a position adjustable stacking table having inter-changeable surfaces of different shapes onto which each part is placed in succession.  The second position of the jaws is adjustable with respect to the first position to accommodate different length parts.  The mechanism is adjustable to permit off-loading of parts of a large variety of different sizes, styles and materials from conveyors of different dimensions. In addition, the mechanism can be altered to accommodate different numbers of lanes of parts simultaneously.
