Title: Geogrids
Inventor: MERCER FRANK B
IPC: B29L28/00
Filed: 1990-09-14
Abstract: A starting material is stretched longitudinally to produce a geogrid. The starting material has pronounced ribs on each face, merging into sloping sides. Between the ribs, there are holes on a square grid. The mean thickness of the longitudinal elements is substantially greater than the mean thickness of the interconnecting elements, and the cross-sectional area of the longitudinal elements is at least 2.5 times the transverse cross-sectional area of the interconnecting elements. The longitudinal elements are stretched out into continuous oriented strands. The centres of the junctions reduce in thickness by at least 10% but substantially less than the percentage reduction at the thinnest parts of the strands.

Abstract: The octane number of light reformate is improved by alkylating the aryl compounds contained therein with olefins contained in a waste gas stream from a fluid catalytic cracking unit by contacting the light reformate with the waste gas in a catalyst bed.  The catalyst structure in the catalyst bed acts as both a catalyst for the alkylation reaction and as distillation structure thus immediately separating the reaction product from the reaction zone to prevent reverse reactions and increase the overall reaction rate.  The resultant product has an increased octane number and a lower specific gravity than the untreated light reformate.

Abstract: A process of treating argentiferous alloy variously called  "zinc crust"  or  "silver crust",  obtained in the separation of silver from lead, removes sufficient zinc in one apparatus and process step to ensure the product is suitable as feed to cupellation.  Suitable feed is defined as material, when partially oxidised in a cupel to remove impurities from silver, results in a litharge that is liquid at typical cupellation temperatures.  The process requires that care be taken to avoid excessive oxidation of the crust during its formation.  No preliminary step to upgrade the crust is necessary,  avoiding the associated expense and effort.

Abstract: EXHAUST MANIFOLD AIR INJECTOR                      Abstract of the Disclosure An air injection device for attachment to the exhaust manifold of an internal combustion engine is described. A one-way or check valve permits air to be drawn into the air injector to the exhaust manifold when the pressure inside is less than atmospheric to allow more complete burn of unconsumed fuel. On the pressure stroke, the valve closes and prevents untreated exhaust gases from exiting the injector. The valve is designed with mechanisms, such as small protrusions, on the valve and/or on the seat or circumferences that the valve contacts to reduce or prevent sticking of the valve. In one embodiment, the valve may be spherical, and in another embodiment, the air injector may be provided with a mechanism to manually adjust the air flow through the injector.

Title: Driven wheel torque control system
Inventor: KITAGAWA HIROSHI
IPC: F16H59/46
Filed: 1991-09-12
Abstract: In reducing a driven wheel output torque by a driven wheel output torque reducing means when slipping of a driven wheel becomes excessive in a vehicle including a torque converter between an internal combustion engine and the driven wheel, an output torque from the internal combustion engine calculated by an internal combustion engine output torque calculating means is first converted into a driven wheel applied torque in consideration of an amplification of the torque in the torque converter by a driven wheel applied torque calculating means. Then, a surplus torque consumed for the slipping of the driven wheel is calculated by a surplus torque calculating means, and a transmittable torque which can be actually transmitted to a road surface is calculated from the driven wheel applied torque and the surplus torque by a transmittable torque calculating means. On the basis of the transmittable torque, a decrement in driven wheel torque is determined by a control quantity determining means . An over-control in the control of slipping of the driven wheel is prevented by taking an amplification of the torque by the torque converter into consideration in this manner.
