Granted: 1980-04-08
Abstract: ABSTRACT OF THE DISCLOSURE    In an internal combustion engine of the recipro-cating piston type which is provided with an exhaust gas recirculation circuit to suppress the generation of NOx and has, two simultaneously operating spark plugs for each combustion chamber. the spark gaps of the two spark plugs are optimumly positioned in the combustion chamber to obtain full merit of the two-point ignition method.  The position of the spark gaps is specified in terms of the distance between them relative  to  the cylinder bore diameter and a vertical distance of each spark gap from the bottom face of the cylinder head relative to the height of the combustion chamber through the same spark gap with the piston at its top dead center.  This positioning of  the two spark gaps is applicable to combustion chambers of a simple shape such as the hemispherical and pancake types.

This results in a reaction mixture consist-ing of an acid phase and an organic phase including the tar-get product. The phases are separated. The organic phase is subjected to neutralization by the treatment thereof with gaseous ammonia used as an alkaline agent. The precipitate of ammonium sulfate is separated and chloroalkane is removed from the remaining solution.     The proposed method makes it possible to obtain the target product with a yield of 88 to 90% and a melting tem-perature of 239 to 239.5°C.     The method prevents the formation of effluents, and the amount of phenol wastes is considerably reduced.

Abstract: ONE-BIT-OUT-OF-N BIT   CHECKING CIRCUIT            Abstract of the Disclosure A one-bit-out-of-n bit checking circuit is comprised of k serially connected detector levels.  A first one of the detector levels accommodates n input signal lines and successively higher ones of the detector levels have one half the number of input signal lines as does the next lower detector level.  Each detector level is comprised of a plurality of logic blocks with each logic block being connected to a separate pair of input signal lines.  Each logic block in each level detects the presence of excitation signals on both input signal lines of the pair of input signal lines and generates an error signal in response thereto.  Each logic block also detects the presence of an excitation signal on one input signal line of the pair of input signal lines and in response thereto propagates the excitation signal through successively higher detector levels to the kth detector level.  The kth detector level generates an excitation signal output in response to the presence of an excitation signal on one and only one of the input signal lines applied to the kth level.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention is a molding process adapted fox the production of plumbing fixtures, such as a toilet whose functional surfaces are resistant to erosion by moving water wherein a ceramic shell forms a liner having external surfaces and the functional surfaces of the plumbing fixture. In the case of the toilet the ceramic shell includes a bowl, siphon trap and a water flush ring.  The molding process includes the steps of coating the external surfaces of the ceramic shell with a layer of resilient material and then suspending the ceramic shell upside down within a female mold member having internal surface  so that the internal surfaces of the female mold member are slightly spaced from the external surfaces of the ceramic shell thereby leaving a gap between the internal surfaces of the female mold member and the external surfaces of the ceramic shell.  The molding process also includes the steps of filling the gap with a catalyzed polyester resin matrix mixed with a filler and pigments and permitting the matrix to bond and to cure to the coated external surfaces of the ceramic shell.  The molding process further includes the step of removing the female mold member thereby producing a plumbing fixture, such as a toilet, that has an attractive exterior appearance which matches other plumbing fixtures to be used in the same room in both their color texture and their design.

Abstract: ABSTRACT     The embodiments of the breakerless magneto device disclos?? herein have a rotor with a permanent magnet imbedded in the periphery thereof which acts in cooperation with the first and second magneto cores to generate a varying flux field in the cores.  The first core has a first winding mounted thereon and the second core, which is mounted next adjacent the first core but insulated therefrom. has a second winding mounted thereon.  The first winding therefore encompasses the first core, the second core, and the second winding.          The second winding provides a trigger pulse to a solid state device which interrupt  the current in the first winding, at or near its maximum value, thereby collapsing the flux field in the first core.  This causes a high voltage to be induced in the secondary winding of the magneto coil which is applied to the spark gap for f?el ignition.  Stable and proper spark timing is achieved with this device.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a new and improved drive system and syringe for syringe pumps, wherein a disposable syringe cartridge having no valves is reliably and precisely mounted, monitored, and driven through repetitive fill and pump strokes.  Prior art disposable syringes are complex and expensive and prone to leakage.  Additionally, they are difficult to mount and remove.  The present invention over-comes these deficiencies by providing a syringe cartridge which has no valves, and the apparatus repetitively and sequentially opens and closes, by means of an external pair of tube pinchers, a pair of intake and output I.V. tubes communicating with the inlet and outlet nipples.  The cartride includes a molded plastic cylinder having inlet and outlet nipples, a plastic piston and piston rod, and a rubber sealing cap defining a conical piston face, a pair of piston sealing rings and a sealing boot.  The syringe has inlet and outlet nipples projecting from one end thereof, and a fixed reference tight source is positioned on one side of one of the nipples.  A fixed photosensor on the opposite side is adapted to receive the light from the reference light source only when the nipple is not interposed between the light source and the photosensor.
