Abstract: ABSTRACT         An apparatus is provided for transferring packs of elongated flat bars in a direction normal to their length. The apparatus includes a first and second set of stationary arms, which are interleaved, and which all extend in the same direction.  Both sets of arms are notched at their upper edges and means are provided to move one set of arms in a closed loop.  Movable arms each have a modified notch at the downstream end with respect to flat bar travel, and this modified notch includes a dog member on at least some of the movable arms, the dog member defining a notch and pivoted to its respective arm adjacent the apex of the notch.  The dog member is counterbalanced to retain the dog member with its notch oriented the same as the other notches of the arm so long as no flat bar  are supported in the notch, but to allow the dog member to pivot when a pack of flat bars is supported in the dog member notch, the pivoting causing the bars to lean in the direction opposite the direction in which the flat bars are moving.  The loop movement of the movable arms picks up, in the dog member notches, a pack of flat bars leaning in the forward direction, and pivots the bars so that all of them lean in the opposite direction, following which the bars are set down on a shuffle bar means adapted to separate the bars and transfer them further in the same original direction.

Abstract: Abstract Minerals, such as vermiculite, which when mined are recovered in plate-shaped form, are efficiently concentrated in a process wherein the mined ore is passed over a roller screen separator comprising a series of revolving spaced rolls.  The collected larger size concentrate can be reduced to desired sizes by passing through a size reducing apparatus and sized by recycling over roller screen separator.  Various preferred aspects of the process such as the use of rubber covered rolls, rolls having different spacing therebetween, etc., are also described.

Abstract: ABSTRACT OF THE DISCLOSURE       Graphite materials with particular utility as catalyst supports are prepared by coating low-ash graphite with a platinum compound in solution in an organic solvent medium including a nonvolatile organic solvent to provide a small proportion of platinum compound on the graphite surfaces. The coated graphite is heated at an elevated temperature in the presence of air or oxygen to remove the solvent and de-compose the platinum compound, leaving elemental platinum disseminated on the treated graphite surfaces.  Using graphite in the form of small particles or coarse powders of inactive material having a surface area below about 1 m2 per gram, the heating is continued for a sufficient length of time to effect a weight lose of graphite particles of as little as 3% while providing a surface area of at least about 3 m2 per gram.  Coherent or molded bodies of similarly inactive graph-ite having a low ash content are treated in a like manner to activate surfaces thereof by depositing small proportions of a platinum compound on such surfaces, likewise followed by heating with access of oxygen and some loss of weight. The activated graphite thus obtained may be impregnated with a catalytically effective amount of a platinum group metal or other catalytically active metal or compound.

Abstract: ABSTRACT OF THE INVENTION         An elongated workpiece carrying a coating, such as paint, containing an oxidizable   solvent is dried or cured in an oven containing a plurality of zones.  Oven gases are circulated in each zone around the workpiece.  To minimize the fuel required for heating the oven and to reduce the volume of oven gases exhausted to the atmosphere, oven gases containing oxidizable solvent vapour are transferred from one oven zone to another where they are incinerated to provide additional heat input to that zone, such incineration also reducing the solvent vapour content of the oven gases and providing zone ventilation.          Oven gases are also incinerated to heat a radiant heater for radiant heating of the workpiece during its p??sage through the oven.

Abstract: ABSTRACT OF THE DISCLOSURE   An electrode and carrier assembly is disclosed for attachment to a biological subject, such as a fetus during labor and delivery to monitor the fetal heart rate.  The electrode structure includes a clip-like body having clamping portions and members adapted to engage cam surfaces within a carrier.  While the electrode structure is housed within the carrier the clamping portions are held apart.  Attachment is accomplished by placing the carrier against the subject and moving the members into engagement with the cam surfaces, whereby the cam surfaces eject the electrode structure from the carrier by the cam action thus allowing the clamping portions thereof to clamp onto the subject's skin.  The carrier may then be removed completely, leaving only the electrode structure with its associated wiring.

Abstract: D-6075 & 7010 VISCOUS SPRING DAMPER     (Abstract of the Disclosure) A viscous spring damper including inner and outer members connected by an elastomeric shear spring and having a main fluid chamber defined therebetween for communication with a second fluid chamber in the inner member through a restricted orifice.  The members are relatively movable for stressing the shear spring and varying the volumes of the chambers while fluid is transferred therebetween through the restricted orifice.  An elastomeric bladder within the second fluid chamber is selectively chargeable with gas pressure for calibrating the damping characteristics, varying the initial spring rate or leveling a vehicle on which the damper is installed.  Axially-spaced circumferential wear rings on the bladder minimize bladder abrasion against the inner wall of the inner member. An elastomeric ring attached to the inner member within the main fluid chamber engages the outer member when the damper bottoms out and this seals the restricted orifice against flow of fluid therethrough from the main fluid chamber to the second fluid chamber.  The restricted orifice includes an elastomeric restrictor having a yieldable flap covering a passage for blocking flow therethrough in one direction while providing flow in a reverse direction.  A load transfer member attached to the inner member opposite from the outer member by another elastomeric shear spring provides two different stages for the damper.
