Abstract: ABSTRACT OF THE DISCLOSURE           An improvement in a method for agglomerating coal particles and removing ashes therefrom at the same time by agitating a mixture of a slurry of fine coal particles and water with a binder is disclosed.  The improvement comprises agitating the mixture at a high speed to form coal agglomerates of small size, and then agitating the mixture at a low speed to make the coal agglomerates larger.  According to the method, the binder adequately adheres to the fine coal particles by the first agitation at the high speed and at the same time ashes are separated from the fine coal particles while preventing the fine coal particles from growing to larger coal agglomerates, and then the particle size of the coal agglomerated is rapidly made large by the second agitation at the low speed through the mutual binding of the fine coal particles, whereby easily recoverable coal agglomerated of large size with high ash removal are obtained.

Abstract: ABSTRACT       In the illustrative embodiment of the invention as described an engine bonnet is articulated to the framework of a motor car.  A pneumatic or gas spring is articulated to both the framework and the bonnet.  The gas spring balances part of the weight of the bonnet when the bonnet is to be opened by hand.  In case of an accident the framework and/or the bonnet may be crushed in longitudinal direction of the car.  In such case the piston rod of the gas spring is pushed inward of the cylinder beyond the normal innermost operational position and a retaining device becomes effective so as to prevent the piston rod from returning towards its outermost operational position.

Abstract: Abstract of the Disclosure A modified vegetable protein adhesive binder and a process for producing the same is disclosed wherein an alkaline protein dispersion is formed of the protein material and said dispersion is treated with a reducing agent in an amount sufficient to react with the disulfide bonds of the protein material in said dispersion.  Initial treatment of the protein material with a reducing agent is followed by reaction of the treated dispersion with a carboxylic acid anhydride such as dicarboxylic acid anhydride, pre-ferably phthalic anhydride in an amount sufficient to modify the pro-tein material such that resultant alkali dispersions of the modified unhydrolyzed protein material have a relatively high viscosity but when used in paper coating compositions containing pigment and other materials such as latex produce relatively low and desirable coating viscosities.  Improvements in pick strength, gloss, water holding and ink receptivity of coatings produced with the modified binder of the present invention is achieved.

Abstract: "PIPELINE STRAINER"                       ABSTRACT OF THE DISCLOSURE              A strainer is provided for removing debris from the gas flow in a pipeline.  The strainer is designed with a view to minimizing the pressure drop across it.  More particularly, the strainer comprises a spherical shell having inlet and outlet means which are connectable into the pipeline.  A circular, concave, perforated plate is mounted within the shell and extends transversely across the path of the gas flow.  The plate functions to retain debris in the flow.  The combination of the spherical shell and the concave plate provides a relatively large "trapping" area having a relatively large number of perforations.  As a result, the pressure drop across the plate is small compared to prior art strainers. In addition, the inlet means is tubular and conical in configuration, so that the entering flow assumes a divergent pattern.  This arrangement results in a reduced pressure drop at the inlet and across the plate.

Abstract: ABSTRACT OF THE DISCLOSURE           A spiral arc circuit breaker is disclosed in which the arc created between breaker electrodes at the time of circuit breaking is confined inside a longitudinally-extending annular gap.  Magnetic fluxes having directions perpendicular to the longitudinal axis of the gap are created in the gap by a magnetic drive coil which surrounds the gap, a plurality of first yokes disposed outside of the gap, and a second yoke longitudinally disposed at the center of the circuit breaker.  The arc created within the gap and the magnetic flux produced by the drive coil cross at right angles so that the magnetic flux can effectively act on the arc to produce spiraling of the arc within the gap.  In contrast to conventional spiral arc circuit breakers, effective spiraling can be achieved even when the separation between the electrodes of the circuit breaker is large.
