Abstract: FUEL SPRAY BAR AND PRESSURE REGULATOR ASSEMBLY  FOR AN INTERNAL COMBUSTION ENGINE            Abstract of the Disclosure A fuel spray bar is disposed in the induction passage of an internal combustion engine for spraying fuel into the induction air stream.  The spray bar contains a pair of separate fuel distribution rails designated as the main (or light load) fuel distribution rail and the auxiliary (or power) fuel distribution rail.  A plurality of spaced orifices communicate each rail with the induction passage.  A pressure regulator assembly is disposed on the fuel spray bar and contains a main pressure relief valve assembly, the outlet of which is in communication with the main fuel distribution rail of the spray bar and an auxiliary pressure relief valve assembly, the outlet of which is in communication with the auxiliary rail.  A motor driven control pump delivers fuel to the inlet of the pressure regulator assembly.  At idle and light engine loading, only the main valve assembly is open so that fuel is sprayed into the induction air passage solely via the main fuel distribution rail and its orifices.  For greater engine loading the auxiliary valve assembly is also open so that fuel is distrib-uted via both rails and their orifices.  The structure of the pressure regulator assembly is configured to render incorrect assembly thereof readily apparent.

Abstract: WATER SLURRY PROCESS FOR MANUFACTURING PHENOLIC        RESIN BONDED FRICTION MATERIALS     ABSTRACT OF THE DISCLOSURE           A process for producing an organic friction article from a composition of materials in a dust free environment.  Water is mixed with the composition of organic materials to produce a slurry.  A fixed volume of the slurry is communicated into a first mold.  The slurry in the first mold is compressed to remove up to 95% by weight of the water to form a briquette.  The briquette is conveyed to a force air oven or dielectric heater where the water is further reduced to about 1% of the weight of the briquette.  This dry briquette is then placed in a second mold and pressed into the shape of a friction pad.  The pressed friction pad is placed in an oven and heated to cure the resin in the composition of materials to complete the manufacture of the organic friction pad.

Abstract: ABSTRACT OF THE DISCLOSURE     A single weighing pan of a top-loading balance is supported upon a vertically-movable carrier spindle which transmits the weight of the pan and of any load placed thereon to an electro-mechanical transducer; such transducer, as known in the prior art, is caused to generate an electrical quantity which may be represented or displayed as an indication of the magnitude of the force displacing the spindle.    A novel force-transmitting arrangement which protects the transducer from damage by shock loads while connecting the weighing pan to the carrier spindle comprises two superposed star-shaped leaf springs, the springs and the spindle together constituting a parallelogram linkage that prevents tilting of the pan under an eccentric load. The spindle is connected to the inner ends of three radial leaf springs of a first resilient member, the outer ends of which are integral with outer ends of radial arms of a second resilient member whose inner arm ends are secured to the weighing pan.  Third and fourth resilient members similar respectively to the first and second members underlie these members and are similarly connected, so that an off-axis load placed on the weighing pan causes the pan to stay horizontal until it abuts a rigid body after 2 millimeters of deflection.
