Abstract: ABSTRACT OF THE INVENTION       Potentially explosive mixtures which can form as a result of accidental contact between a concentrated aqueous solution of ammoniacal silver salt and a concen-trated solution of a strong alkali are inhibited in an improved multi-part system for electroless deposition of silver on an activated surface by simultaneous admix-ture of the diluted parts thereupon.  Accordingly, an improved method for inhibiting formation of explosive conditions and compounds in a mixture formed by contact-ing concentrated aqueous ammoniacal silver salt and a concentrated solution of alkali is provided, whereby an effective amount of an explosion inhibitor is provided either in combination with the ammoniacal silver salt, in which case sufficient extraneous ammonium ions are provided to stabilize the explosion inhibitor, or in the strong alkali, or a portion of the explosion inhibi-tor is provided in each of said ammoniacal silver salt and strong alkali.  Conventional reducers for ammoniacal silver salt can be utilized together with said explosion inhibitor.

Abstract: ABSTRACT          A wide-band compression coupling for flexible hose, piping or tubing is disclosed which has a sleeve assembly ex-tending circumferentially around the adjacent ends of the tube or pipe.  The sleeve assembly has an axially extending, radially projecting crown with a unique clamping means at the crown to tighten the sleeve assembly around the ends of the tubes or pipes.  The clamping means comprises a pair of opposed spacer members extending axially on each side of the crown and a center member within the crown interposed between the spacer members.          The center member is adapted to be forced radially outwardly when the spacer members are drawn together by fastener means.          As the center member moves radially outwardly, the sleeve assem-bly crown is pulled with it to tighten the sleeve assembly around the ends of the tubes or pipes.  The coupling is capable of joining together tubes or pipes having unequal outer dia-meters and can accomodate tubes or pipes within a range of outer diameters.

Abstract: ABSTRACT OF THE DISCLOSURE         A suspension system for wheeled vehicles, particu-larly adapted to extended travel suspension systems for armored wheeled vehicles in which each of the front and rear vehicle wheel assemblies are mounted on a trailing arm sus-pension.  The front suspension system includes an axle housing supported at either outboard end by a bell crank assembly, each including a trailing arm pivotally mounted to the axle housing at one end and at the other to a pivotal support on the vehicle hull or frame with a second shorter crank arm acting on a coil spring to resist arm motion by compression of the spring.  A constraining link pivotally connected to each axle housing end constrains the motion of the axle housing on the trailing arms to maintain the attitude of the axle housing while a sway bar constrains the side-to-side motion of the axle housing, each wheel assembly is mounted to be steerable on the axle housing, with driving power delivered to the wheels by axle shafts dis-posed within the axle housing.  Within each coil spring is disposed a stack of rubber bumper elements compressed with the spring while a pair of rubber bushings is provided at each pivot point of each of the trailing arms, the damping action of the stack bumpers and bushings performing a shock absorbing func-tion.  The rubber bushings also act as torsional springs and to accommodate limited tilting motion of the axle housing. The trailing arms each are inclined inwardly to closely posi-tion the coil springs, which extend generally horizontally within the nose of the vehicle hull to minimize the overhead clearance required and provide ready access to the coil springs. An independent trailing arm suspension supports the rear wheels, with a bell crank assembly compressing respective coil springs with driving power delivered by means of universal joints from a fixed differential gear unit.  The axle housing sup-porting the front wheels passes beneath a tunnel formed in the hull to accommodate its vertical travel, while the vehicle wheel assemblies are disposed in recesses in the vehicle hull, covered by displaceable fairing panels which serve to accom-modate the extended upward movement of the wheels during extreme displacement of the suspension system.

Abstract: Abstract An ignition spark timing circuit with switchable hysteresis for an internal combustion engine is disclosed. A crankshaft sensor produces a periodic input sensor signal, having a predetermined period, which initiates the action of a programmable voltage slope generator that produces a predeterminedly varying signal.  This varying signal serves as an input to a comparator which also receives a switching threshold input, and the comparator output is utilized to determine the time occurrence of spark ignitions.  A switchable feedback path is provided between the output of the comparator and its switching threshold input such that hysteresis for the comparator threshold input is provided during critical portions (TC) of the time period of the crankshaft position sensor signal when the comparator is expected to produce output signal transitions that determine the occurrence of spark ignitions.  At other portions (TN) of the time period of the crankshaft position sensor signal, the comparator output cannot affect the threshold input of the comparator.
