Abstract:
A constant-current light sensing system employs a constant-current diode in series with the power lead to a photoconductive cell. This diode provides a substantially fixed current through the cell and enables the system to be designed such that it can make maximum use of the linear portions of the cell's output response curve, and maximum use of the range of a potentiometer's settings. The cell used in conjunction with the system is received in a housing that is easily mountable to a wall or ceiling surface by an adhesive material.
Abstract:
A fuel injection system employs injectors having energizing coils and means for generating an actuating pulse to the injector. The system includes a correction means for applying a correction to the injector actuaing pulse to correct for the effect of at least one incidental system variable on the effective response of the injector to the actuating pulse. The incidental system variables are: the impedance of the energizng coil, the specific resistance of the wire used in the coil and the voltage supply in the fuel injection system. The correction means may be a constant current source drivng an output transistor biased to operate in a proportional conduction region.
Abstract:
A fuel injection system employs an electromagnetically actuated injector connected to a source of fuel and a variable width, constant current electrical pulse source controlled by engine operating parameter sensors, to energize an injector coil in timed relation to the engine operation and thereby vary the fuel volume provided to the engine as a function of the parameters. A circuit including the injector coil modifies the time constant of an R-C circuit in the pulse source to modify the pulse width as a function of the voltage across the injector coil, which varies as a function of fuel temperature in the injector to maintain the fuel mole weight provided to the engine independent of variations in the fuel temperature adjacent to the injector.
Abstract:
An inductive coupler provides an interface between a power line and a communication device which communicates via the power line. The power line operates at a potential between four and 140 kilovolts while accommodating a current having a frequency between 45 and 65 hertz, and the communication device operates substantially at ground potential. The inductive coupler includes a split ferrite core having material selected to provide a substantially flat frequency response between one and 50 megahertz. The coupler also includes a clamping mechanism allowing the inductive coupler to clamp around the power line or around a utility line connected to the power line. Further, the coupler includes at least one lead for communicatively connecting the inductive coupler to the communication device. The inductive coupler forms an air gap when the inductive coupler is clamped. If the coupler is insulated, the insulation is also used for the air gap.
Abstract:
A method of dispensing a flowable conductive paste onto a greensheet from a dispensing apparatus comprising an orifice member having first and second surfaces and a bore therethrough between the surfaces, a pressurized chamber adjacent the orifice member first surface containing the paste, and a punch having a face movable through the orifice member bore. The method comprises positioning the punch outside the orifice member bore such that the punch face is spaced from the orifice member first surface, flowing a desired amount of paste onto the punch face, moving the paste on the punch face through the orifice member bore until the punch face extends beyond the orifice member second surface, and contacting the workpiece with the paste while still on the punch face to deposit the paste on the greensheet. The method then provides for retracting the punch until the punch face is substantially coplanar with the orifice member second surface, and then cleaning the punch face and coplanar orifice member second surface to remove any residual paste thereon.
Abstract:
A process and apparatus for shelled almond pasteurization includes counter flowing raw shelled almonds in saturated steam for a four second interval to elevate the exterior surface of the shelled almond to a temperature exceeding 160 degrees Fahrenheit. Thereafter, the pasteurized almonds are counter flowed for a two second interval in dry air before discharge to further processing or to containers for shipment. Almond taste, texture, and appearance are unchanged during the pasteurization process. The apparatus includes a steam ladder (1) defining downward paths which alternately vary the major surfaces of the shelled almonds to exposure to upwardly counter flowing steam, and an underlying drying ladder (2) for drying the raw shelled almonds upon exit from the steam ladder.
Abstract:
A liquid herbicidal composition is provided, comprising: a. 20 to 35 percent by weight, based on the total weight of the composition, of a water-soluble herbicidal ingredient; b. a C12-C16 alkyl ether sulfate; c. an organic solvent; and d. an alkyl polyglucoside. The composition is stable; i. e., it occurs in a substantially continuous, single phase at temperatures as low as −20° C. It also has a viscosity of no more than 2000 cps at temperatures as low as 0° C.
Abstract:
A method for separating and filtering solid particles from a hydrocarbon slurry liquid includes two or more filter sections in fluid communication with the hydrocarbon slurry. At least one filter section is comprised of one or more filter elements having a mean pore size of less than 10 microns, and at least one other section is comprised of one or more filter elements having a mean pore size of 10 microns or greater. The small pore filter (less than 10 microns) will exclude all or substantially all of the smaller catalyst fines produced by catalyst particle attrition. The liquid product removed from the small pore filters will be substantially free of particulates. The large pore filters (10 microns or greater) will exclude larger catalyst particles, but will allow the smaller fines to pass. The liquid product removed from the large pore filters will contain the fines generated from catalyst particle attrition.
Abstract:
A media game that employs a method for randomly shuffling through a large set of video and/or audio clips stored on readable media using a media player, such as a DVD player, is disclosed. In addition to the readable media, the game also includes a game board, moveable play pieces, trivia question cards, random name cards, a numbered die, and a challenge die. The game board can be converted from long play to short play by lifting the endmost sections of the game board and placing them next to each other on top of intermediate sections of the game board. A path circumnavigates the game board and appears to be continuous in both long and short play modes. The begin and end regions reside at least partially on the endmost sections and appear as unbroken shapes when configured for both long and short play.
