Abstract: ENGINE BRAKING APPARATUS                           ABSTRACT           Pressure relief apparatus for an internal combustion engine compression relief engine brake is dis-closed.  Normally an existing pushrod is used to drive a master piston which in turn controls the motion of a slave piston which opens an engine exhaust valve.  The problem of assigning such additional function to the pushrod is that an increased load may be experienced which may exceed the design capacity of the pushrod.  The invention solves this problem by providing a bi-stable relief valve located in a high pressure hydraulic fluid circuit which interconnects the slave and master pistons together with damping means adapted to damp out rapidly the oscillations of the valve during the period of its opening so as to maximize the flow of hydraulic fluid through the bi-stable valve and minimize the time required to relieve the pressure in the high pressure hydraulic system of the compression relief engine brake.  The damping means comprise a spring controlled valve guide which inhibits premature reseating of the bi-stable valve and maximizes the average opening of the valve during its operating period.

Abstract: "HEADLIGHT GLARE SHIELD FOR USE WITH           SLOTTED FAIRING"                  ABSTRACT OF THE DISCLOSURE             This invention relates to a glare shield for motorcycle headlights mountable within an inverted generally U-shaped slot in a transparent fairing placed in front thereof, the shield being characterizied by an elongate web of flexible elastic material having a center section bordered on both ends by arcuate pleated sections separating the latter from a pair of identical end sections bearing an acute angular relationship to the center section approaching 90°.  The shield also includes an integrally-formed rim on the outside of the web having a more or less H-shaped cross section adapted to be releasably retained in forwardly-facing flush relation within an inverted and recessed U-shaped slot in the fairing that extends along the top of the headlight and down along both sides thereof.  The pleats are located on top of the web in upstanding relation thus leaving the underside with flat wedge-shaped surfaces between the pleats that engage the headlight and block most of the reflected light therefrom.  The invention also encompasses the improved combination between the shield and fairing that eliminates the need for a detachable insert in the latter while, at the same time, maintaining a smooth uninterrupted aerodynamic surface.

Abstract: ABSTRACT OF THE DISCLOSURE        High rate upflow filtration is conducted using a bed of buoyant media in a filter vessel unobstructed by cross-sectional, media-confining screens.  A horizontal trough structure collects filter effluent and makes it possible to clean the bed by diffusing air into the liquid below the bed so that average fluid density in the bed is reduced. The reduction in fluid density results in expansion of the bed as media particles descend by gravity.

Abstract: ABSTRACT OF THE DISCLOSURE         A self-plumbing, counter-rotating trolley and track suspension system for supporting an operable wall panel is disclosed.  The suspension system comprises a trolley assembly, including a pendant bolt to provide a common axle on which a pair of counter-rotating discs are rotatably mounted in spaced apart alignment.  The track-contacting surface of each disc is spherically formed, with each surface generated from a common centerpoint but having unequal radii so that the surfaces generated by the radii have curvatures which are similar but are not congruent.  The suspension system also includes a track having a pair of vertically spaced and diametrically arranged rails, each rail defining a cylindrical surface which is generated from the same common centerpoint of that of the discs, the locus of which lies above the rail-contacting surface of the upper disc.  When the trolley is mounted for movement along the track, the discs of the trolley will always maintain mating contact with their respective rails, even when the center line of the trolley and the track are in misalignment.

Abstract: A METHOD FOR THE SUSPENSION POLYMERIZATION            OF STYRENIC MONOMERS          ABSTRACT OF THE DISCLOSURE         In a method for the suspension polymerization of one or more styrenic monomers, optionally with up to 35% by weight, based on the total monomers, of one or more non-styrenic vinyl monomers, a suspension of the monomer(s) is produced as droplets dispersed in a continuous water phase.  The monomer(s) in the suspension is then partially polymerized by free radical initiation in the presence of at least one substantially water insoluble free radical initiator until 50% to 90% conversion is achieved. Thereafter the amount of substantially water insoluble free radical initiator(s) in the suspension is increased and the suspension polymerization is completed, again by free radical initiation.  The temperature of the suspension is maintained at at least 110°C during the entire polymerization.
