Abstract: SYSTEM FOR COMBUSTION OF GASES     OF LOW HEATING VALUE            Abstract of the Disclosure A gas turbine system for the recovery of power from fuel gases having a low heating value, i.e., below about 80 Btu/scf, and usually in the range of 35 to 70 Btu/scf, has an external catalytic combustor.  The catalytic combustor is divided into a primary and a secondary catalytic combustion chamber with a heat exchanger between the two combustion chambers.  In the preheater the low heating value gas mixed with combustion air is passed in indirect heat exchange with products of combustion from the first combustion chamber before the low heating value gas is delivered to the first combustion chamber.  The turbine system is particularly advantageous in recovering power from low heating value gas in which the combustibles are hydrocarbons, primarily methane.

Abstract: ABSTRACT OF THE DISCLOSURE         A back pressure regulator and non-return valve is provided herein.  It includes a hollow plug having an open inlet end and a closed end having a central aperture therethrough.  A closure cap is hermetically slidably disposed within the hollow plug.  A plurality of outlet perfora-tions are provided from the hollow plug, the apertures being disposed along helical paths along the outer periphery thereof.  Finally, a tubular re-silient diaphragm sleeve envelopes the apertured portion of the hollow plug, the resilient sleeve being secured to the hollow plug only adjacent the open inlet end thereof the tubular resilient diaphragm sleeve having walls of non-uniform thickness.  Control of the outflow through an annular outflow path between the hollow plug and the tubular resilient diaphragm is provided by changing the effective length of the hollow plug and to al-ter the number of the outlet apertures in the effective length of the outlet plug remaining.  This thereby increases the threshold gaseous pres-sure required to move the thicker portions of the diaphragm away from the hollow plug to provide the annular outflow path.  Non-return function is provided by gas pressure on the outside of the tubular resilient diaphragm which seals the annular outflow path.

Abstract: AUTOMATICALLY ARRESTABLE CURTAIN TYPE                   ROUTE INDICATOR     ABSTRACT    A curtain and roller destination sign for display from a bus or the like vehicle is rotatable by an electric motor.  Each name or number destination display segment of the curtain has a foil strip attached to its rear part to be sensed by a proximity switch which sends pulses so an electronic processor which counts and stores the count of the pulses provided by the moving curtain completing intermittently the signals from the proximity switch.  A manually operated thumbwheel switch is connected to the processor to indicate by the numeral setting on it for comparison by the processor of the count from the proximity switch at the curtain.  When the manually set switch setting corresponds to the count from the curtain the motor is stopped to arrest the curtain at the required setting and to thereby display the destination corresponding to the manual setting made on the thumbwheel switch.
