Abstract: TITLE:  FUEL-AIR MIXER FOR CARBURETORS    Abstract of the Disclosure A fuel-air mixing improvement for the carburetor of an internal combustion engine breaks droplets of fuel progressively into finer drop-lets as they pass through the fuel "jet" or supply tube between the fuel reservoir and the carburetor induction tube.  A twisted wire mesh screen is mounted within the supply tube.  The twists increase in pitch from an upstream end to the discharge of the tube so that fuel droplets and air being pulled through the screen are progressively more frequently engaged by the screen and the droplets are thereby broken into finer droplets, resulting in an extremely fine spray. This is accomplished before this rich fuel and air mixture enters into the air passing through the carburetor induction tube.  The rich mixture then leaving the supply tube has already developed a swirling path and readily mixes with the air being drawn through the induction tube and venturi.  To assure that the wire mesh screen will not overly obstruct the fuel and air passage through the supply tube, a tapered ring is mounted to the venturi for guiding or restricting air flow to a path primarily through the venturi rather than through the open space between the venturi and remainder of the induction tube.  Also, for adjustment purposes an air-bleed mechanism is provided whereby air may be taken upstream of the venturi and directed into the associated fuel reservoir adjacent the intake end of the fuel supply tube.  Adjustment is provided with this arrangement such that air may be bled selectively into the area to be premixed with the fuel prior to its reception and passage through the spiral screen within the fuel supply tube.

Title: Exhaust gas purification and heat value  recovery
Inventor: FUNK HARALD F
IPC: F04B37/08
Filed: 1978-11-20
Granted: 1982-04-27
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for treating hot ex-haust gas to purify the gas and to recover the heat values therein includes removing particulate matter from the gas, purifying the gas by subliming or "freez-ing out" harmful, less volatile components and discharg-ing the more volatile components as purified gas. The sublimed or "frozen out" components are collected and neutralized or utilized.  The heat values may be re-covered prior or subsequent to purifying, such as by spraying a power fluid into the gas to cool and in-crease the volume of the gas and then expanding the gas in an expansion turbine to further cool the gas and to produce shaft work.  Alternatively, the heat values may be recovered from purified, hot gas by transferring the heat energy of the gas to a power fluid which operates in a Rankine cycle external com-bustion engine to do shaft work.

Abstract: ABSTRACT OF THE DISCLOSURE           A sheet carrier on transfer drums in multi-colour rotary printing presses serves the purpose of receiving the freshly printed sheet on the circumference of the drum in such a way that any spoiling of the printed image is prevented.  For this purpose, use is made of sheet carrying elements having a support edge upon which the sheet can rest.  The invention makes it possible to arrange the sheet carrying elements in such a way that they support the sheet in a non-printed place.  In order to achieve this, individual sheet carrying elements can be pivoted out of the working position and the sheet carrier can be displaced axially and radially on the drum surface.

Abstract: IMPROVED LAUNDRY DRYER                 Abstract of the Disclosure An improved laundry dryer having a novel hot air compart-ment structure that heats recirculated exhaust air and fresh make-up air.  The novel hot air compartment structure, in preferred form, includes an attic chamber defined by the dryer's housing,  The attic chamber is divided into upper and lower subchambers, a heater housing being positioned within the lower subchamber.  The heat source in the heater housing serves to directly heat fresh make-up air and recirculated exhaust air simultaneously within the heater housing, and also serves to heat up the upper and lower subchambers of the attic chamber.  The recirculated exhaust air is introduced into the upper subchamber, thereby pre-heating same prior to intro-duction into the heater housing, and is subsequently introduced into the heater housing in a vertically downward flow path fashion.   The fresh make-up air is introduced into the pre-heated lower sub-chamber, thereby pre-heating same prior to introduction into the heater housing, and is subsequently introduced into the heater housing in a generally horizontal flow path.  The vertically down-ward and horizontal flow path of the exhaust air and make-up air, respectively, into the heater housing provide for intimate admixing of those two air flows within the heater housing.  The flow paths of the recirculated exhaust air and fresh make-up air through the hot air compartment structure is controlled by novel port structure which provides optimum contact of the air flows with the heated sur-faces of the upper and lower subchambers, and the heater housing, and with the heat source itself, to achieve maximum heat transfer and, thereby, optimum energy use.
