Title: Bioconversion reactor
Inventor: MCCARTY PERRY L
IPC: C02F3/00
Filed: 1986-02-03
Granted: 1992-01-07
Abstract: ABSTRACT            A bioconversion reactor for the anaerobic fermentation of organic material.   The bioconversion reactor comprises a shell  enclosing  a  predetermined  volume,  an   inlet port through which a liquid stream containing organic materials enters the shell,  and an outlet port through which the stream exits the shell.  A series of vertical and spaced-apart baffles are positioned within the shell to force the stream to flow under and over them as it passes from the inlet to the outlet port.  The baffles present a barrier to the microorganisms within the shell causing them to rise and fall within the reactor but to move horizontally at a very slow rate.  Treatment detention times of one day or less are possible.

Abstract: POWER STEERING SYSTEM FOR MOTOR VEHICLES            Abstract of the Disclosure A power steering system for motor vehicles for assisting the manual steering effort includes an electromotive drive unit which acts upon the steering shaft in a sense corresponding to that of the manual steering.  The operating mode of the drive unit is dependent on the vehicle speed and the instantaneous steering torque manually applied to the steering wheel. At low vehicle speeds and high manual steering torque the drive unit is caused to run at high speeds; at high vehicle speeds and low manual steering torque the drive unit is caused to run at low speeds.  A fluid friction clutch is interposed between the drive unit and the steering shaft.  In addition to transmitting force from the drive unit to the steering shaft, the fluid friction clutch assists in damping forces which are transmitted to the steering wheel by the steering system in the form of shocks or rotary oscillations.

Granted: 1991-09-24
Abstract: ABSTRACT OF THE DISCLOSURE    An optical recording medium includes a silver grain layer containing a large number of blackened fine silver grains and a coloring matter layer containg coloring matter on a base board and the coloring matter has an ability of absorbing near-infrared ray.  When laser beam having a density of optical energy more than a boundary which represents a threshold with respect to the density of optical energy is radiated to the optical recording medium, a part of the latter is deformed to form a plurality of convexities which will be utilized as optical recording pit.          The recording pits formed in this way are detected by presence or absence of reflection of radiated light whereby the content of optical recorded informations can be read.          The optical recording pits are not deformed further irrespective of how long a reading light comprising laser beam having a density of energy less than the threshold is repeatedly radiated to the optical pits.  Accordingly, any reduction of S/N ratio of a signal does not take place as time elapses.
