Title: Infant-restraining protective seat having inflatable seat belt
Inventor: KAMIYAMA MISAO
IPC: A44B11/25
Filed: 1992-10-20
Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is an infant-restraining protective seat having an inflatable seat belt, in which an infant seat belt (6) is maintained in the shape of a belt under ordinary conditions.  When the a tongue (5) is engaged with a buckle device (4) in order to fasten the belt, gas flow holes (4a) and (5a) are brought into registration to form a single gas flow passageway.          Under ordinary conditions, however, the gas flow holes (4a),  (5a) are closed by caps (11),  (12).  Since a gas generator (9) does not operate under ordinary conditions, the protective seat (1) exhibits an infant-restraining function similar to that of the conventional protective seat for infants.  At the time of an emergency, the gas generator 9 generates a high-pressure gas that breaks the caps (11),  (12) and flows into the infant seat belt (6).  As a result, the infant seat belt 6 inflates substantially instantaneously and in reliable fashion.  Accordingly, a seated infant is restrained by the inflated seat belt 6 in a reliable manner.

Abstract: An improved vertical, centrifugal separator (100) includes a drive mechanism (142) to which is connected both a flight assembly (138) and a screen assembly (166). An inlet assembly (124) is positioned above the flight and screen assemblies for material (M) to be separated to be fed into the separator. This material is captured between the flight and screen assemblies and falls downwardly therebetween as separation occurs. A pocket assembly (144) integral with the screen assembly is positioned between a discharge port of the inlet assembly and the upper end of the flight assembly. The pocket assembly creates a "basket" for catching material introduced into the separator through the inlet assembly, and replaces the upper portion of the screen assembly which previously was used to catch this material. The screen assembly includes a rotor (182) having a plurality of spokes (196) defining an outlet for separated solid material. The spokes have attached wear pads (210) to protect them from impacts with the solid material thereby to prolong the useful life of the rotor. An outlet assembly (216) for the solid material is positioned beneath the rotor. The outlet assembly has a side wall (218) lined with ceramic plates (242) to resist impacts from the solid material falling into the outlet assembly.

Title: Sea-water hydro-barrage
Inventor: TRUONG KE LONG
IPC: F03B17/00
Filed: 1992-11-09
Abstract: Abstract This is the Second Generation of my invention: 'New Sea-water Hydro-barrage'.  The design will generate electric power 24 hours a day.  The water flow needed to turn the turbines of the alternators is situated under the tidal down level of the sea.            An input tunnel will take in the water from the sea at the aforementioned level.  The stream will turn the turbines to make electricity.  While turning, these helices will also accelerate the flow which will be propelled up back to the ocean.  The fluid will travel through a half-elliptic canal curved upward.  It is coated with ceramic or any other gliding substance or polished.  At the end of the canal lays a suction pump that will suck up the liquid and will throw it down to the sea via half-open slope.  Sunk in this going down-ward half duct is the turbine of a smaller alternator. The output fluid force helps produce the kilowatts of power used by the pump.

Title: Grain Processor
Inventor: LE GIGAN DOMINIQUE
IPC: B07B13/16
Filed: 1992-11-19
Abstract: A grain processor for separating and measuring components of a sample of grain as it passes through a rotary sieve having two or more sieving sections having different perforations so that selective separation is made on the basis of the size of the particles in the sample.  The separated particles in each of the sieving sections are passed through a densimetric column containing a stream of pressure-adjustable air generated by a blower, the air stream removing impurities from the separated grain or different density impurities which is channeled into a weighing hopper which measures the weight of the grain or impurities and registers the information in a unit provided with data processing and recording circuits, including microprocessor means.  To control the movement of the air in the separating columns, the motor-driven rotary sieve and the motors coupled to the blowers are provided with tachometers which provide rotational speed pulses to rotation control circuits in the unit which, in turn, provides an input to motor controllers associated with the motors driving the fans and the rotary sieve.  Each of the rotation control circuits is provided with a motor-driven potentiometer which has a rotor rotating together with an optical coded disc which provides an output to adjacently-positioned optical heads providing an input into the unit which registers the position of the potentiometer without requiring a reference reading.  Alternatively, each of the rotation control circuits may use, in lieu of the motor-driven potentiometer, a solid-state electronic interface between the microprocessor means and the motors.  The weighing hoppers and associated scales used in the grain processor are provided with lock-down devices for transit purposes.

Title: Insect repellent tent fabric
Inventor: SAMSON RICHARD D
IPC: E04H15/54
Filed: 1993-01-15
Abstract: 1. A coated tent fabric having a fabric substrate with a coated outer surface normally exposed to degrading elements of the atmosphere and a coated inner surface normally shielded by the fabric substrate from the degrading elements of the atmosphere. The coatings on the outer and inner surfaces of said fabric substrate each contain a polymeric binder, flame retardant chemicals and water repellent chemicals. Permethrin is added as an insect repellent to the coating on the inner surface of the fabric substrate, whereby the fabric substrate acts as a barrier that inhibits migration of the permethrin to the outer surface of the fabric and consequently inhibits exposure of the permethrin to the degrading elements of the atmosphere, thereby increasing the length of time the permethrin is an effective insect repellent.
