Abstract: TITLE            Two-Speed Clutch ABSTRACT OF THE DISCLOSURE   A two-speed clutch is shown according to the preferred embodiment of the teachings of the present invention for the selective rotational relation of an input shaft with a first or second sheeve unit having different diameters.  The first sheeve unit is rotatably mounted to the input shaft.  The second sheeve unit is mounted to a housing in turn rotatably mounted to the input shaft.  The clutch includes a friction disc which is located between and frictionally interrelates with the first sheeve unit or the housing.  The housing includes a single, reciprocally mounted piston for moving the friction disc.  Utilizing a two-speed clutch of the present invention eliminates the requirement of two separate and complete drive units as in prior techniques.          Furthermore, since the housing performs multiple functions, i.e., rotatably mounts the second sheeve unit to the input, slidably mounts the piston, acts as the interface for the second sheeve unit with the friction disc, and other functions, the two-speed clutch of the present invention greatly reduces the number of parts and results in a simplicity of construction.  Furthermore, the two-speed clutch of the present invention provides a relatively dust and other element free environment for the piston and splined interconnection of the interfacing friction disc with the input.

Abstract: ABSTRACT         The electrically operated clutch controlling operation of the compressor is regulated by a damped pressure switch. The pressure switch has a diaphragm which moves in response to pressure variation to actuate the switch.  The force acting on the diaphragm is opposed by spring force.  The housing is provided with a damping chamber between the diaphragm chamber and the restricted passage in the inlet. The restricted passage is the clearance between the hole drilled in the metal insert and the wire fixed in the hole. The restriction is selected relative to the damping chamber so the switch will not cycle more than four times per minute when sensing pressure at the outlet of a finned coil evaporator in an automotive air conditioning system operating under light load.

Abstract: Abstract of the Disclosure Feed hydrocarbons comprising propane and butanes are cracked to selectively maximize  the production of ethylene or propylene by contacting the feed hydrocarbons with a cracking catalyst, adapted to convert the feed hydrocarbons to less saturated hydrocarbons, under conditions sufficient to thus crack the feed hydrocarbons, to thereby selectively maximize  the  production  of ethylene,  and,  at  least intervally, hydrogen sulfide or a hydrogen sulfide precursor is added to the feed hydrocarbons to thereby maximize the production of propylene. Preferred catalysts which may be utilized in the process and which are highly selective to the production of ethylene, as opposed to propylene, (in the absence of hydrogen sulfide or hydrogen sulfide precursor) include mixed oxides  of manganese and magnesium, mixed oxides of manganese and Lanthanum Series metals and/or niobium, mixed oxides of iron and magnesium and mixed oxides of iron and Lanthanum Series metal and/or niobium.  The effective life of the catalyst, particularly for the selective production of ethylene,  is increased by carrying out the process in the presence of steam.  When the catalyst contains manganese, the steam is optional whereas, when the catalyst contains iron, the steam is essential.  The life of the magnesium based catalysts as well as their selectivity, particularly to ethylene, can also be extended by adding small promoting amounts of oxides of calcium, strontium, barium, tin, antimony, silicone, aluminum, titanium and/or chromium.  All of the above promoters are useful in the iron/magnesium catalysts except the calcium, strontium, barium, tin and antimony.  Only chromium is useful as a promoter for the Lanthanum Series and niobium based catalysts.

Abstract: PROCESS FOR REMOVAL OF POLLUTANTS      FROM WASTE GAS EMISSIONS                         ABSTRACT Chlorine is injected in a gaseous liquid or solution form into a hot (greater than 100°C) gas stream for the purpose of oxidizing objectionable components in the gas stream, such as, but not restricted to, SO2 and NOx, when the oxidized form of the gases is more readily removed from the gas stream.  After sufficient reaction time, the gas stream mixture passes through water scubbers for the further removal of the components from the gas stream.  Acidic and basic compounds of the gas stream and halogens, including excess chlorine, are also removed in the scrubbers.  The pollutants remain as the corresponding oxidized acids or salts in the process effluent solution.
