Abstract: VEHICLE STEERING APPARATUS                  Abstract of the Disclosure An improved power steering apparatus includes a pressure modulation assembly which modulates the fluid pressure transmitted from a power steering control valve to a power steering motor.  The modulation assembly varies the fluid pressure output from the steering control valve as a direct function of variations in vehicle speed.  This results in relatively easy steering for parking and low speed maneuvers and a firmer feel for maneuvers at higher speeds.  The pressure modulation assembly is connected in series fluid communication with and between the power steering control valve and the power steering motor and includes a pair of pressure modulation valves.  Fluid for actuating the power steering motor flows from the power steering control valve through the pressure modulation valves to the power steering motor.  The pressure modulation valves are biased closed by the output pressure from an auxiliary pump which is driven at a speed which varies as a function of vehicle speed.  Thus, the pressure of the fluid delivered to the power steering motor is reduced by the pressure modulation valve to an extent determined by the magnitude of the biasing force derived from the speed dependent auxiliary pump.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a process and to an apparatus for treating solutions containing tritiated water wherein an electrolyte, such as soda, is added to the  solution,  the  solution  obtained  then  undergoes electrolysis in order to release tritium in the gaseous state.  Working  takes  place  in  an  electrolytic  cell having  a  cathode  made  from  a  metal  which  aids  the diffusion of tritium, e.g.  a Pd-Ag alloy coated with porous palladium black. The cathode forms a separating wall between the  solution  to  be  electrolysed  and  a tritium reception compartment.  The tritium which has diffused through the wall of the cathode is recovered in the compartment.  Use for  the recovery of tritium from  effluents  resulting  from  the  reprocessing  of irradiated nuclear fuels.

Abstract: MECHANICAL SEAL ASSEMBLY            Abstract:      An  improved mechanical  seal  assembly  (10) comprising a generally stationary seal ring (12) and rotatable seal ring (16), each with opposed seal faces  (20,22),  the  stationary seal  ring  being connected to a stationary housing by elastomeric keys.   One of said seal rings is constructed of a material such as a carbon graphite composition which is more brittle than the other which is constructed of a much harder less brittle material.  As in most seals of this character, the seal faces are lubri-cated by a fluid film flowing radially across the opposing faces.  In the absence or upon failure of the film, the rings can seize, generally resulting in a breakage of or other damage to the more brittle seal ring.  However, the elastomeric connecting keys provide a cushion for absorbing dynamic forces in the tangential direction, to distribute bearing loads substantially evenly and to allow radial deflections of the stationary seal ring relative to the housing due to thermal and pressure effects.

Abstract: Abstract An end release type of buckle for safety belt harness in vehicles and a method of assembly wherein a channel shaped elongate chassis transversely supports a latch and a latch blocking element, the latter pivotal at one end and biased toward blocking the latch.  A closure plate biased to follow insertion and removal of a buckle tongue is reciprocably mounted for longitudinal movement to the web of the chassis.  A release slider is provided which reciprocates to remove the blocker against its bias and to depress or open the latch.  A tubular case encloses and detentably assembles the chassis and operably guides the release slider while supporting the operating bias applying elements.  A cup-like cover is pressed longitudinally over the case and is detentably located and secured to said case.  When not in use the latch is held open by the closure plate.  When a tongue is pressed into the buckle the closure plate retreats from blocking the entry slot and the latch obeys the bias to lock.  Upon locking the tongue, the blocker bar secures the latch against withdrawal until the release slider depresses the latch after tilting the blocker bar away from the latch.

Abstract: Abstract The invention relates to a method for directing a certain amount of gas under the liquid surface in a solution reactor (1), advantageously into its bottom part, for dispersing the gas into small bubbles and for distributing it as evenly as possible over the entire cross sectional area of the reactor  (1).  When the gas discharges and disperses from the flexible-structured member (2) according to the invention, the reaction force produced by the discharging gives the dispersing member (2) a whip-like movement having a continuously decreasing radius of curvature, this movement producing strong mechanical mixing in the liquid. This is further enhanced by the strong gas jet discharging from the end of the dispersing member (2) and changing its place randomly. Owing to this strong mixing, the solid in the reactor remains in motion and maintains continuously the good degree of suspension and does not accumulate in piles on the bottom of the reactor  Depending on the amount of the gas, the rising gas bubbles produce in the reactor effective vertical flows which further mix the solid.     Figure 1 has been selected for the abstract.

The regulating pressure may be either air or hydraulic pressure.  Shock obsorber means (26, 27, 28) is preferably provided to restrict movement of the balance piston.

Abstract: Abstract of the Disclosure A dual processor system in which one processor is dedicated to input/output tasks while the other is dedicated to high level language tasks when operating as a 16-bit machine.  The processors include a first microprocessor which is an 8-bit machine, and a second microprocessor which is a 16-bit machine.  The first processor has a memory associated therewith which may, for example, be a 64K memory while the second processor has a larger capacity memory.  The second procesor does not access the memory of the first processor, however, the first processor can access a portion of the second processor's memory.  Access to the second processor's memory is controlled by an arbitrator that is operated by system software to prevent access conflicts.  For boot-up during power-up operaton, a boot ROM is used, attached to the 8-bit processor having stored therein a boot strap program that is initially loaded into the 8-bit processor memory.  If the operating system loaded from a diskette indicates 8-bit software, then the 16-bit processor is maintained reset or halted.  On the other hand, if the operating system is a 16-bit system, then the boot program loads the 16-bit memory making the 16-bit processor the main processor.  The 8-bit processor then functions as an I/O processor.  This boot-up procedure allows the 8-bit processor to turn on first and makes the system initially appear as an 8-bit processor system.  In this way the system is compatible with software written for an 8-bit machine even though the system is normally run and identified as a 16-bit machine.
