Abstract: IMPROVED MOTOR FUEL COMPOSITION                    Abstract of the Disclosure Motor fuel composition having detergent properties are disclosed and claimed which are particularly useful in spark-ignition, internal combustion engines.  The fuel compositions of the present invention contain certain additives which either substantially eliminate, mitigate against, or maintain at a low level, deposits which would otherwise form in the carburetor, in the intake valves and ports, and in the combustion chamber, including the spark plugs.  Such carburetor and intake system (induction system) deposits are to be avoided since they tend to restrict the flow of air through the carburetor especially at idle and at low speeds and/or cause improper valve closing and sluggish valve action.  These conditions produce rough engine idling, stalling, and can also result in excessive hydrocarbon and carbon monoxide exhaust emissions.  Combustion chamber deposits are to be avoided since they cause an increase in octane requirement, emissions and cause preignition. The fuel additives of the present invention include for induction system deposit control an ester selected from a dimer or timer acid ester or from other polycarboxylic acid esters, especially dicarboxylic acid ester.

Abstract: APPLICATION OF:  Kenneth K. Knapp FOR:  HYDRAULIC CONTROLLER                        A B S T R A C T     An electro-hydraulic control for a hydrostatic trans-mission to control a number of functions of the transmission or the pump or motor of the transmission.  The transmission includes a variable displacement pump driving a fixed displacement motor along with the appropriate standard valving for control of the displacement of the pump and the high and low pressure conduits communicating hydraulic fluid between the pump and the motor.  An electro-hydraulic control valve is supplied to port a varying pressure of fluid to the standard controller used to vary the displacement of the pump.  The control valve includes a spool biased in one direction in a housing to port fluid from the charge pump of the transmission to the standard controller.  A fluid chamber is in communication with the other end of the spool and with the fluid from the charge pump.  A variable orifice communi-cates the fluid chamber with a drain.  The size of the orifice is controlled by an electrical force positioning valve which receives a signal representative of the location of the swashplate of the pump.  Depending upon the pressure of the fluid in the fluid chamber the control valve will directly vary the pressure ported from the charge pump to the standard controller.  A needle roller has one end in contact with the end of the spool communicating with the fluid chamber.  A high pressure signal is provided via a shuttle value across the high and low pressure conduits of the transmission to the other end of the needle roller. Accordingly, the control valve is responsive to both the pump displacement and the highest pressure within the transmission thereby making it a torque limiting controller.  Various modifications can be made within the spirit of the invention to control the fluid pressure within the fluid chamber and against the one end of the needle roller to change the function of the control valve.

Abstract: ABSTRACT OF THE DISCLOSURE An internal-combustion spark-ignition V-8 piston engine has a main exhaust gas reaction chamber positioned between the two banks of cylinders.          Each cylinder has a main combustion chamber and an auxiliary combustion chamber connected by a torch nozzle restriction.  Valved intake passages supply lean mixture to the main combustion chambers and rich mixture to the auxiliary combustion chambers.  A spark plug is associated with each auxiliary combustion chamber.  Valved exhaust passages supply hot exhaust gases to auxiliary exhaust gas reaction chambers, each of which projects through an insulated wall of the main exhaust gas reaction chamber, and discharges into it.  Each of the auxiliary reaction chambers is substantially smaller in volume than the main reaction chamber and helps to minimize unwanted pollutants such as unburned hydrocarbons and carbon monoxide in the exhaust gases by maintaining the exhaust gases at relatively high temperature and for relative-ly long time periods before discharge into the atmosphere, and over a wide range of engine speeds and loads.  A separate air pump is not required.

Abstract: A B S T R A C T           There is disclosed herein an antenna for generating a rotating pattern.  The pattern is generated electronically, and no physically moving parts are required.  An exemplary embodiment of the antenna radiates a cardioid pattern which rotates at a 15Hz rate for use as a Tacan beacon.  The structure of the antenna is in the form of a conic monopole above a ground plane.          A plurality of vertical modulator fins, providing controllable shorting elements, and a plurality of suppressor posts are added.          The modulator fins have associated diodes to which are applied a bias current along with modulating signals which cause the resistance of the diodes to vary with respect to the flow of RF current at the frequencies of interest (such as in the neighbor-hood of 1 GHz for Tacan usage).  Other details of the physical structure of the antenna are shown and described herein, as well as an electronic system for controlling the diodes.  In a typical application, the antenna is mounted on an airplane to enable the airplane to serve as a beacon.  In this instance, the exemplary system as shown and described herein is adapted to be coupled with the synchro system of the airplane compass for providing a reference with respect to magnetic north so as to properly electronically relate the rotating pattern of the antenna to magnetic north while the airplane upon which the antenna is mounted changes its flight direction.

The pattern is sensed, preferably in the disclosed apparatus, by an array of detec-tors, and the sensed pattern employed as an identification and characterization of the cell.  The pattern may be analyzed, or selected portions of the pattern employed, to differen-tiate cells embodying different features.  The apparatus and process is especially useful for rapid identification and differentiation of leucocytes and other types of mammalian cells, the radiation for such analyses preferably being infrared radiation.  A preferred structure for individually illuminating such cells with radiation and for sensing their differential light scattering pattern is disclosed.

Abstract: PNEUMATIC SYSTEM FOR CONVEYING GRANULAR MATERIAL   ABSTRACT OF THE DISCLOSURE         A pneumatic seed planter utilizing air pressure to dispense the seeds in a central hopper to a plurality of laterally spaced seed planting assemblies.  Mounted on the planter is a system for dispensing granular chemicals such as fertilizers, herbicides and insecticides from a separate hopper to the rows planted by the seed planting assemblies.          The system uses air pressure from the planter (rather than a mechanical drive) to convey the granular material out of the separate hopper to the planting assemblies.  More specific-ally, air is directed upwardly through an opening in the bottom of the chemical hopper and into a material conveyor tube spaced from the opening.  The granular chemical is drawn through the space and into the conveyor tube by the air stream.  A plurality of delivery tubes is connected to the conveyor tube for directing the chemical to the respective plurality of planting assemblies.  The rate of delivery into the conveyor tube is controlled by adjusting the position of the tube relative to the inlet opening -- the rate increasing with an increase in the space between the opening and the tube.  Means are included for directing an auxiliary flow of air into the space to assist movement of material into the conveyor tube.  Control means are provided for varying the auxiliary flow in response to varying the space between the opening and tube.  Further control means are provided for starting and stopping the dispensing of chemicals automatic-ally in response to movement of the planting assemblies between operative and nonoperative modes.
