Abstract: TITLE:  LOW MOLECULAR WEIGHT COPOLYMERS AND TERPOLYMERS  AS DEPRESSANTS IN MINERAL ORE FLOTATION               ABSTRACT OF THE DISCLOSURE        Low molecular weight copolymers and terpolymers of the general structure:                               wherein R1 is hydrogen or a methyl radical, R2 is hydrogen or COOM and M is a hydrogen, alkali metal cation or ammonium ion, exhibit excellent depressive action in the flotation of non-sulfide mineral ores  thereby resulting  in  improved selectivity and recovery.  The low molecular weight copoly-mers and terpolymers, perform depressing action without resulting in any associated flocculation in the flotation system.  These copolymers and terpolymers can be combined with other known depressing agents in nonsulfide  ore flotation processes such as starch, dextrin, water soluble gum and the like, to obtain equivalent or improved selec-tivity and recovery than would be obtained using these depressants alone.

Abstract: SELF-CLEANING SCREEN FOR THE COOLING AIR INLET             OF AN ENGINE ENCLOSURE Abstract of the Disclosure In a self-propelled combine, an engine cooling air screen is cleaned continuously by a rotating exhaust sweep moving close to its external surface.  Air is drawn into the sweep and exhausted through the cooling fan by way of an air passage having an inlet opening in the center of the screen communicating directly with the exhaust sweep and an outlet immediately ahead of the inlet side of the fan.  Power for rotation of the sweep preferably comes from the propeller action of air passing over the sweep which has air deflector or propeller surfaces at its extremities.  Alternatively, the sweep may be driven by a more conventional blamed propeller rigidly connected to the sweep but offset rotationally from it.

Abstract: ABSTRACT OF THE DISCLOSURE     A fire and explosion detection system for discriminating between radiation produced by a source of fire or explosion to be detected and radiation produced by a source of fire or explosion not to be detected, comprises two radiation detectors respectively responsive to the intensity of radiation in different, narrow, wavelength bands to produce respective electrical outputs.  One detector responds to a narrow wavelength band including 4.4 microns (to detect hydrocarbon fires).  A rate of rise unit and a threshold unit responsive to the first detector produce signals of one type when the rate of rise of, and the value of, the intensity of the radiation received by that detector exceed predetermined values.  A ratio unit: measures the ratio of the intensities of the radiation respectively received by the two detectors and produces a signal of the opposite type when the ratio indicates that the source of radiation is a fire or explosion to which the system is not to respond.  An AND gate produces a fire and explosion indicating output only when the signals of the first type exist in the absence of the signal of the opposite type.

First and second temperature sensors sense the temperature of the fluid stream across the thermal power transfer device, and this information is used to determine a heat capacity rate of the fluid in the fluid stream.  Additional non-intrusive temperature sensors sense the temperature of the fluid stream as it passes through and across a thermal power sink or heat source and provides a temperature differential.  These temperatures are processed in a control circuit, and the thermal power added to or extracted from the fluid stream is determined in the control circuit by multiplying the measured temperature differential by the heat capacity rate of the fluid stream.

Abstract: A METHOD OF SUPPLYING FUEL TO AN INTERNAL COMBUSTION ENGINE, AND AN ENGINE USING THE METHOD. It has been found possible to achieve fuel savings by heating diesel fuel prior to injection to higher temperatures than those currently used, and in particular, for practical reasons, to temperatures in the range 70.degree.C to 120.degree.C. However, to obtain the saving it is necessary to simultaneously modify the volumetric flow rate of fuel in order to maintain its mass flow rate in spite of two factors which tend to reduce the effective mass flow rate with increasing temperature, namely: volumetric expansion; and increased fluidity. Not only is fuel saved by heating to such temperatures, but the maximum power and torque which an engine is capable of delivering are also increased.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention provides a process for preparing water-soluble polymers with a controlled low molecular weight, the molecular weight of the polymer being controlled by the presence of a calculated quantity of methallylsulfonate monomer during the polymerization reaction.  The molecular weight of the polymer varies inversely with the quantity of methallylsulfonate monomer that is present.  Low molecular weight water-soluble polymers are useful as oil well drilling additives, dispersants and the like.
