Abstract: ABSTRACT OF THE DISCLOSURE A multiple air motor unit in which the motors are mounted in series to permit the exhaust air from the first motor to be used in driving the second motor.  The exhaust air from the second motor assists in driving the third motor.  The exhaust air from the third motor assists in driving the fourth motor.  A line extending from the intake side of the first motor provides additional air pressure to the intake side of each of the succeeding motors so that each motor is operating under the same operating pressure.  The motors are geared to gears on a common shaft which extends through a universal joint to the apparatus to be driven.           The unit may be used to help power a motor vehicle if desired.

Abstract: CAPACITOR BANK PROTECTION RELAY             ABSTRACT OF THE DISCLOSURE            A protective relay for shunt capacitor banks which is arranged to provide a neutralizing signal which balances any initial unbalance inherent in the capacitor bank which may be due to slight differences in the capacitors which make up the bank so that initially the output signal is substantially zero whereby the sensitivity of the relay to the failure of one or more of the parallel series con-nected  capacitors is considerably increased without the necessity of amplification or other complications.  The relay further is rendered insensitive to varying unbalances present in the polyphase transmission line, not caused by capacitor failure, by the use of resistive elements connected to compensate for line unbalance.  These resistors will be more secure against failure than the capacitor elements used in the shunt capacitor banks.

Abstract: ABSTRACT OF THE DISCLOSURE Supported catalyst compositions incorporating preformed materials comprising the reaction product of organophosphorus compounds such as the organophosphates and organophosphites with chromium trioxide, wherein the organic moiety is a hydrocarbon radical, e.g., alkyl, aralkyl, aryl, cycloalkyl, or the like or combinations thereof. Typical supports constitute an inorganic material of high surface area, especially a high pore volume (> 1.96 cc/g) silica xerogel. Catalytically promoted polymerizations of 1-olefins proceed efficiently to products of specially adapted utility for molding, and particularly the production of blow molded articles. The polymerization activity of the catalyst compositions is promoted by heating in a dry, oxygen containing atmosphere. The catalysts are utilized alone or in conjunction with other catalytic ingredients such as organometallic and/or organo non-metallic reducing agents.

Abstract: PROTECTION CIRCUITS                   ABSTRACT OF THE DISCLOSURE          A protection circuit is provided which incorporates a reed relay whose contacts form the circuit breaker of an electrical appliance.   The winding of the reed relay is supplied with a rectified alternating current derived from a current transformer coupled to the supply line to the appliance.  In order to avoid periods of zero current in the winding, the winding is also supplied with a rectified alternating current from a source which is out of phase with that supplying the supply line.   Failure of the current on the line will cause the contacts to open.  Preferably the relay has a set of self latching contacts to prevent re-energisation of the winding once de-energised.   A manually operable reset switch is provided in series with the self latching contacts.

Abstract: Abstract of the Disclosure A combination gas valve in which means associated with the main dia-phragm valve is provided for opening the valve in a stepped manner. The combination valve includes an electromagnetic operator which controls the pressure differential across the main diaphragm valve so as to open and close it. The main valve seat surrounds a concentrically located recessed secondary valve seat. Slidably located on a stem extending from the main diaphragm valve, a secondary valve plate having a plurality of orifices therein is adapted to mate with the secondary valve seat so that initial open-ing of the main valve allows flow only through the orifices in the secondary valve and further opening of the main valve disengages the secondary valve from its seat, thus allowing full flow. On full flow conditions, a servo reg-ulator provides a regulated output.

Abstract: ABSTRACT OF THE DISCLOSURE   A cargo-carrying articulated ship system having icebreaking capa-bilities is provided herein.  It includes of a powered cargo-carrying ves-sel having an icebreaking hull from, a bow and a stern, and a powered loco-motive vessel having an icebreaking hull form, a bow and a stern.  In addi-tion, a connection system is provided for connecting the cargo-carrying ves-sel and the powered locomotive vessel at concave and convex respective bow and stern confugurations to provide an articulated cargo-carrying locomotive vessel and vessel system.  This connection system comprises winches secured to the powered locomotive vessel with lines therefrom tied to the cargo-carrying vessel and is operable by interrelated winding-in and paying-out of the lines by operation of the winches.  This controls lateral movement of the cargo-carrying vessel relative to the locomotive vessel.  Not only does this system minimize longitudinal movement between the locomotive ves-sel and the cargo-carrying vessel, but it also positively provides indepen-dently operable cargo-carrying vessel control means which are operable inde-pendent of the control means for the locomotive vessel.  Thus, the cargo-carrying vessel is maneuverable in lateral directions independently of the direction of movement of the locomotive vessel.  Thus a cargo-carrying ship used in ice infested waters is provided having optimal split between cargo-carrying capability and propulsion capability.

Abstract: ABSTRACT OF THE DISCLOSURE           Solid state folded leaf spring force trans-ducers are fabricated by batch photolithographic and etching techniques from a monocrystalline material, such as silicon.  The folded leaf spring structure includes elongated gaps separating adjacent leaf spring leg portions, such elongated gaps being oriented parallel to a crystallographic axis of the monocrystalline material.  In a preferred embodiment the monocrystalline material is of diamond cubic type and the leaf spring gaps extend in mutually orthogonal directions parallel to the <01?> and <o??> crystallographic axes, respectively. In a preferred method of fabricating the spring structure, the structure is etched from a monocrystalline wafer by means of an anistropic etchant so as to more precisely define angles and dimensions of the resultant spring structure.  In one embodiment, the gaps between adjacent leg portions of the spring structure are sealed in a fluid tight manner by means of oxide membranes left intact upon etching of the spring structure. In an accelerometer embodiment, sensing masses of equal weight are affixed to opposite sides of the spring structure for dynamically balancing same.

Abstract: ABSTRACT OF THE DISCLOSURE    A multipole homopolar inductor motor/alternator for a flywheel drive includes a rotor assembly on the outside of the stator which functions as the flywheel.  Locating the excitation field winding on the stator between two stacks of stator laminations enables the rotor assembly to be operated at much higher temperatures than a wound rotor, without detrimental effect on overall efficiency.  The rotor assembly is also operable at much higher speeds than would be possible if the rotor were wound, resulting in apparatus better adapted to store energy mechanically.

Abstract: ABSTRACT OF DISCLOSURE   A mixing bowl having an outwardly flared inner surface is rotated around its axis at a speed which is great enough to cause a film of liquid within the bowl to be moved upwardly by centrifugal force to the rim of the bowl.  A liquid is introduced into the bottom of the bowl at a rate that permits an unbroken film of liquid to form within the bowl and move from the bottom to the rim. Particulate material is uniformly distributed in a radial direction within the bowl to contact the liquid film and mix therewith.  The rim of-the bowl is shaped to interact with an adjacent stationary surface to shear the liquid and particulate material mixture to increase the uniformity of the mixture.  A basin is positioned around and under the rim of the mixing bowl to collect the mixture as it is thrown off the outer edge of the rim.
