Abstract: APPLICATION OF:   George W. Goetz FOR:   FLUID GENERATOR     A B S T R A C T     A device for generating pressurized fluid for inflating inflatables such as for a vehicle occupant restraint.  The present generator is of the combustible chemical type having a tubular housing with radial flow discharge port means.  Combustible chem-ical gas generating material is disposed within the housing and annularly about a central thin wall tubular casing.  Longitudinally fast-burning booster charge means is disposed within the central casing and is ignited at one end of the casing.  Upon ignition, the booster charge burns progressively along the length of the tubular casing causing progressive longitudinal rupture for nearly instantaneous ignition of the portions of the gas generating material adjacent the casing.  The resultant substantially in-stantaneous ignition of the gas generating material along the full length thereof produces uniform radial burning of the gas generat-ing material.

Abstract: ABSTRACT OF THE DISCLOSURE A radio controlled remote brake system for a railway train having a caboose equipped with a motor driven pressure regula-ting valve device and an equalizing reservoir that is charged from the train brake pipe pressure via the regulating valve device.   When a brake application is made at the locomotive by operating the conventional engineer's brake valve device, a radio signal corresponding to the brake valve position is transmitted to the caboose where it is compared with a feedback signal corresponding to the instantaneous position in which the caboose regulating valve is set by its drive motor.  When the brake control and feedback signals match, the caboose regulating valve is set to effect a reduction of the caboose equalizing reservoir pressure in accordance with the locomotive equalizing reservoir pressure reduction resulting from opera-tion of the engineer's brake valve device.  During brake release and charging, an initialization circuit controls the regulating valve drive motor so that the regulating valve is set to the caboose brake pipe pressure when the brake pipe is fully charged.  Due to brake pipe gradient, this setting differs from that of the locomotive brake valve and is com-pensated for by a gradient memory circuit which modifies the feedback signal so that the degree of pressure adjustment provided by the caboose regulating valve matches that of the locomotive.   A relay valve device at the caboose operates in response to a reduction or caboose equalizing reservoir pressure to provide a reduction of caboose brake pipe pressure corres-ponding to the reduction of brake pipe pressure at the locomotive.

Abstract: ABSTRACT OF THE DISCLOSURE          Transparent colored materials having low bulk densities and high magnetic permeabilities are obtained by encasing silicaceous particles in a sheath of magnetic or magnetically-attractable metal, which are then heat-treated.  The magnetic composite particles are prepared by the solution phase thermal decomposition of transition metal carbonyls in the presence of the silicaceous particles with a suitable suspending medium.  Air and moisture are excluded from the reaction vessel and the contents are heated with agitation so that the carbonyl boils and the mixture is refluxed until the temperature rises to that of the suspending medium whereupon coating of the silicaceous particles with elemental metal is complete.  The mixture is cooled, the heads washed, air-dried, and recovered.  The metal coated particles are then heated in an ambient atmosphere for between about 2 to about 120 minutes at a temperature of from between about 50°C and 700°C.  Particles having transparency, color, and magnetism in the same body are obtained.

A flow of cool-ing fluid is maintained from the surface through the circuital path defined by the annular cross-section regions and the fluid coupler, particularly including the exterior surface of the production tubing string.        The fluid is maintained at a temperature and flow rate such that the pregnant leach liquor flows in the pro-duction tubing string between the leaching interval and the surface at a predetermined reduced temperature.

Abstract: IMPROVED CONDUCTIVE PLASTIC WITH METALIZED   GLASS FIBERS RETAINED IN PARTIAL CLUMPS                      ABSTRACT    Articles of a thermoplastic having an improved level of electromagnetic shielding are molded from plastic pellets that have a core of metalized glass fibers that are arranged to partially disperse through the molded article as individual fibers and partially to remain in clumps of generally aligned closely contacting fibers.  The clumps have approximately the length of an individual fiber but they are substantially wider than an individual fiber.  Improved conductivity is attributed to increased electrical bridging between fibers that is provided by the width of the clumps of fibers.
