Title: Internal combustion engine with dual induction system  and with fuel injection system to discharge fuel into secondary induction system
Inventor: NAKAGAWA YASUHIKO
IPC: F02B31/08
Filed: 1978-12-18
Granted: 1981-07-21
Abstract: ABSTRACT OF THE DISCLOSURE:           A dual induction system is provided wherein a single inlet valve controls both the primary and secondary induction systems thereof and wherein for each cylinder a single injector is provided which injects fuel into the secondary induction system so as to impinge on the back of the valve head of said single inlet valve.  An air flow meter senses the total air flow through the primary and secondary induction systems and outputs a signal to a control apparatus which in turn controls the amount of fuel injected by the injector.  The air flow through the primary induction system is controlled by a manually controlled throttle valve, while the second is controlled by a vacuum motor responsive to the air flow in the primary system.  The primary induction system is adapted to introduce air into the cylinder so that the air swirls around the axis thereof while the secondary system is adapted to introduce air into the cylinder under given modes of operation of the engine so as to impede the swirl produced by the primary system.  Thus a rapid swirling lean mixture can be combusted at low RPM while a richer mixture having a lower swirl rate can be combusted at higher RPM.

Abstract: CERAMIC BASE AND CAP USEFUL IN              FIRING CERAMIC SHELL MOLDS     ABSTRACT OF THE DISCLOSURE    Disclosed is a preformed ceramic base useful in firing an open-ended ceramic shell mold having a mold base prior to metal casting.  The ceramic firing base includes a working surface having a majority of flat surface portions for supporting the mold base during firing and one or more groove-like surface portions which define gas circulation passages from the outside atmosphere into the open mold bottom when the mold base is placed in supported relation on the flat surface portions.  The ceramic firing base thereby enables firing of a green shell mold while maintaining mold base flatness and circulation of furnace gas into the mold cavity to minimize mold hot spots.  Also disclosed is a preformed ceramic firing cap to be used in conjunc-tion with the ceramic firing base, the firing cap being adapted to cover the open top end of the shell mold to prevent foreign particulate from entering the mold. The firing cap includes a working surface comprising a majority of flat surface portions for resting on the top of the mold and one or more groove-like surface portions extending from inside to outside the mold for purposes of gas circulation.

Granted: 1982-06-22
Abstract: ABSTRACT OF THE DISCLOSURE          The present invention rotates to a novel physical form of gluten to be utilized as a self-binder for meat-like products excluding the need of egg albumen. The novel physical form contains an inert material bound within its matrix and is characterized by its net-like fibrous structure, which fibers have a diameter smaller than 2 mm diameter and a viscosity of at least 50.000 cps.         The novel physical form of gluten is obtained by agitating vital wheat gluten with a reducing agent at a temperature below 70°C and incorporating during said agitation the solid inert material having a particle size below 5 cm diameter. A preferred type of said inert material is testured vegetable protein.         The product obtained according to the invention can be successfully utilized in most industry, enhancing the binding properties of the moat and improving its texture as an extender.

The second conveyor conducts the hoods between and along upper and lower paths of travel and is so located with respect to the first conveyor that when each hood is shifted from its upper path of travel to its lower path of travel, it will engage one of the platens traveling in its horizontal path of travel to form a chamber therewith.  Means are provided in association with each chamber for evacuating the chamber.  Means are also provided in association with each chamber for applying a clip to the bag to close the bag about the product. Means are provided in association with each chamber to trim the excess of the bay following clipping.  Finally, means are provided to devacuate each chamber after the bag has been clipped and trimmed.  The second conveyor is so configured that when each hood is shifted from the lower path of travel to the upper path of travel it disengages from its respective platen, exposing the clipped and trimmed bagged product on the platen for further processing.
