Abstract: A STAGGERED CONFIGURATION FOR   WANKEL ENGINE SPARK PLUGS          ABSTRACT OF THE DISCLOSURE       A rotary internal combustion engine is disclosed having circumferential type cooling circuit for the rotor housing and a plurality of spark plugs extending through the trochoid wall of the rotor housing at a vertically rising zone of said circuit. The plugs are contained by bosses extending through the coolant flow passage; the bosses are arranged to stagger the up-stream sides of said bosses with respect to controlled flow of coolant thereabout, thereby increasing flow control, increasing heat transfer, and preventing a collection of vapor which may act as an insula-tion film hindering heat transfer between said bosses and coolant flow.  The centerline of said bosses are preferably skewed with respect to both a plane bisecting the flow longi-tudinally and a plane bisecting the flow transversely, whereby the spark terminals of said plugs may be maintained within narrow offset limits on opposite sides of a center-line of the gas side of said trochoid wall.

Abstract: BUTTABLE DISPLAY PANEL          Abstract of the Disclosure The display panel is a dot matrix panel and comprises relatively large gas-filled cells which are arrayed in rows and columns and are adapted to be energized in different combinations to display characters.  The cells are formed by strip-like column cathode electrodes having localized active areas formed therein to comprise the active cathodes, the localized areas of all of the cathodes being arrayed in rows and columns.  The cathode electrodes and their localized areas are shaped and spaced apart so that, in the final panel, a suitable seal area is provided and panels can be butted together.  An insulated plate having horizontal apertures, each aligned with a row of cells, overlays the cathodes, and a face plate is seated on the insulating plate carrying horizontal anodes formed with localized active areas arrayed in rows and columns, each aligned with one of the cathode areas and each carrying a quantity of a phosphor material.  Electrical energization of selected anodes and cathodes causes selected cells to glow and display a character.

Abstract: ABSTRACT OF THE DISCLOSURE         The specification describes a rotary piston machine having parallel and internal axes, comprising displacement cells which are formed between a stator and a rotor, alternately enlarge and contract between two extreme volumes, and are connected to connections by way of a distributing valve consisting of a valve portion fixed to the stator and a rotary slide that is fixed by a shaft to rotate with the rotor.  The rotary slide is adjustable through a limited angle with respect to the rotor by means of an adjusting apparatus-having at least two chambers associated with each connection.  A circular piston machine, is particularly described, in which a pinion enclosed by a hollow wheel is connected to the rotary slide by a cardan shaft.  A signalling device is provided, which transmits a signal between the instant at which one of the extreme volume displacement cells passes through the neutral position and the instant of the pressure change in this cell as caused by the distributing valve, and the chambers of the adjusting apparatus are connectible to the connections by way of a three-position regulating valve which moves during the period of the signal impulse into its open position effecting shortening of the next impulse.

Abstract: MANGANESE-AND-MAGNESIUM-ACTIVATED               STRONTIUM SULFIDE PHOSPHORS                        Abstract Manganese-and-magnesium-coactivated strontium sulfide phosphors are both photoluminescent and cathodolumi-nescent.  The incorporation of small amounts (100 to 3750 ppm) of magnesium into manganese-activated strontium sulfide phosphors shifts the CIE emission color coordinates from about x = 0.323 and y = 0.650 for the magnesium-free phosphor to about x = 0.370 and y = 0.611, for the maximum amount of incorporated magnesium.

Abstract: ABSTRACT OF THE DISCLOSURE The disclosure relates to a weighing and computing system for determining and displaying the total net price of a series of commodity items including items to be weighed for determining individual net prices from unit weight prices and items of fixed net prices which are not to be weighed.  The system includes a weighing mechanism comprising a platform upon which a commodity item to be weighed is placed for pro-viding reference and gross weight signals corresponding to the load on the platform with the reference weight signals corresponding to the total load of all previous commodities in the series which have been weighed and the gross weight signals corresponding to the total load of all the previous commodities weighed and the load of the next commodity in the series to be weighed and a selectively operable unit price device for providing a rate signal corresponding to a unit weight price for a commodity to be weighed or an item net price signal for a commodity of fixed net price.  The system also includes a computer comprising a reference weight memory device for storing reference weight signal developed by the weighing mechanism, a subtracting facility for determining the difference between the gross weight signal and the reference weight signals to provide a net weight for each commodity to be weighed, a multiplying facility responsive to the weight difference determination for multiplying each net weight by a corresponding rate signal for providing a net price for each of the weighed commodities and net price accumulating means for accumulating all of the net prices.  The system further includes a display coupled to the net accumulator for displaying the sum total of the net prices.  In a preferred form, the system determines a plurality of average net weights during predetermined time intervals until two consecutive average net weights are the same.  At such times the system computes the net price of the commodity being weighed.
