Abstract: ABSTRACT OF THE DISCLOSURE               The present invention is concerned with an electric insulator for average, high, and very high voltages, charac-terized in that the ribbed coating thoroughly coats a supporting central body and is made of an ethylene-propylene elastomer (EPR) having high elastic,anti-tracking, anti-erosion, ageing resistant, self-extinguishing, and water-repellency charac-teristics, said ribbed coating being shaped as ribs and supported by a sleeve-shaped tubular layer prepared from an ethylene-propylene elastomer (EPR) of qualities and charac-teristics identical with those of the EPR elastomer constituting said ribs.  The coupling of said ribbed elastomeric coating with said central body, of said ribs with said sleeve, and of self-curing at room temperature,based on low-unsaturation olefinic polymers, analogous and compatible with the ethylene-propylene blend (EPR) of which the ribbed coating is made.The present invention is concerned also with the process to obtain the same.  The electric insulator according to the invention shows a radical and definitive solution of the problem of achieving a perfect adherence between the r.b.g.f. body and the ribbed coating.

Abstract: Abstract of the Disclosure A vault or strongroom includes unitary and self-contained equipment for providing life-support within the sealed vault-enclosure.  The carbon-dioxide content of the atmosphere within the enclosure is monitored and a pump is operated if the monitored value exceeds a predetermined value, typically 1% or 2%. Operation of the pump pumps air of the atmosphere through material that absorbs carbon dioxide and this, together with operation of a fan to circulate air in the enclosure is continued until the monitored content has been reduced, typically to 0.5%.  Oxygen (or air) is released from cylinders for replacing the absorbed carbon dioxide and maintaining an oxygen level of about 18% or 19% in the enclosure.  Release of oxygen is regulated by a valve device to maintain a variable - pressure (or oxygen level) - of the atmosphere within the enclosure substantially constant or within predetermined limits.  The pump is operated concurrently with release of the oxygen.

Abstract: Abstract of the Disclosure A method of matching a golfer with golf balls with varying aerodynamic properties is disclosed along with apparatus which is useful in carrying out the method.  The "launch conditions" with which the golfer "launches" a golf ball are measured to determine the golf ball dimple pattern most suitable for a particular golfer or to determine modifications which should be made in his style of play or club design.  The apparatus provides a combination of a camera with an electronically operated shutter and associated flash synchronization equipment so that a first flash of light is obtained after the shutter has opened, when the golf club strikes the ball, and a second flash of light is obtained following the first flash by a controlled time period, the shutter than closing.  The photographic image as recorded during the two flashes can be used to determine the initial spin velocity and the launch angle, which parameters can be used in the disclosed method.     dap/???

Abstract: ABSTRACT OF THE DISCLOSURE        A typical embodiment has an end fitting for a nuclear reactor fuel element that is joined to the control rod guide tubes by means of a nut plate assembly.  The nut plate assembly has an array of nuts, each engaging the respective threaded end of the control rod guide tubes.          The nuts, moreover, are retained on the plate during handling and before fuel element assembly by means of hollow cylindrical locking cups that are brazed to the plate and loosely circumscribe the individual enclosed nuts.  After the nuts are threaded onto the respective guide tube ends, the locking cups are partially deformed to prevent one or more of the nuts from working loose during reactor operation.  The locking cups also prevent loose or broken end fitting parts from becoming entrained in the reactor coolant.

Abstract: ABSTRACT OF THE DISCLOSURE         A missed commutation detection circuit for use with a power inverter circuit which employs optically isolated gates to provide signals indicative of the state of a pair of SCR power switching devices.  The gates are connected to combine the signals via a NOR logic arrangement to generate a missed commutation control signal whenever both the SCR's are concurrently in a conductive or unblocked condition.  The commutation control signal thus generated feeds a one-shot multivibrator which generates an isolation signal for a preselected time period.  The isolation signal opens a normally closed current isolation switch connected intermediate the DC input bus and the invertor SCR's which cuts off current to the SCR's permitting them to return to their blocking state. After the duration of the isolation signal from the one shot, the isolation switch is again closed and the circuit is permitted to attempt normal operation.  The inverter is again isolated from the DC supply upon recurrence of the missed commutation condition.

Abstract: ABSTRACT OF THE DISCLOSURE An anti-locking means includes an assembly attached to move with a wheel of a vehicle.  The assembly includes a spring biased inertia wheel movably mounted to a manifold.  A valve connected to control the application of braking pressure is normally held closed when the inertia wheel and mani-fold are rotated at the same rate by the wheel.  When the vehicle wheel is decelerated at an excessive rate, the inertia wheel overcomes the bias of the spring and continues to rotate about the manifold to open the valve and pre-vent braking pressure from being applied to the wheel.
