Abstract: ABSTRACT OF THE DISCLOSURE           Brush arrangement for a composite dynamoeletric machine comprised of two or more axial air-gap machines joined by a common shaft. Brush are located near the outer radial periphery of each of the axial air-gap machines, on at least one axial side of each machine. The brushes are inclined such that the outer extremities of the brushes are further removed from the common shaft than are the inner extremities of the brushes (that contact the commutator). The result of such a construction is that two or more axial air-gap machines, joined by a common shaft, can be mounted in close proximity to one another with a minimum of interference from the brushes or their associated assemblies.

Abstract: LOCATING UNDERGROUND URANIUM DEPOSITS            ABSTRACT OF THE DISCLOSURE         Underground uranium deposits are located by placing pairs or dosimeters each about 5 to 18 mg/cm2 thick underground in a grid pattern.  Each dosimeter contains a phosphor which is capable of storing the energy of alpha particles.  In each pair one dosimeter is shielded from alpha particles with more than 18 mg/cm2 thick opaque material but not gamma and beta rays and the other dosimeter is shielded with less than 1 mg/cm2 thick opaque material to exclude dust.  After a period underground the dosimeters are heated which releases the stored energy as light.  The amount of light produced from the heavily shielded dosimeter is subtracted from the amount of light produced from the thinly shielded dosimeter to give an indication of the location and quantity of uranium underground.

Abstract: ABSTRACT OF THE DISCLOSURE A stressed membrane space enclosure having a supporting frame com-prising a plurality of spaced individually separable arch-like members with a strip of fabric stretched between each adjacent pair of arches and by means of which separable arches the fabric is tensioned.  The feet of the arches rest on load-bearing pads that are individually shiftable as during the frame spreading for the purpose of tensioning the fabric and that each finds its own proper resting place when all the stresses on the structure have been nor-malized and is then secured against unauthorized movement by ground anchors, thereby achieving the greatest possible strength and stability of the support-ing frame.  The fabric is applied in reinforced elongated strips one such strip between each adjacent pair of spreadable frame members and stretched to a predetermined tension to bear maximum loads of wind and snow. Reinforc-ing the strips of fabric in the direction of the tension stress and ensuring a high uniform tension on each strip aids in the discharge or dispersal of heavy environmental loads and the overall strength of the structure.  A load regulated power jack may be used to spread the adjacent pairs of frame members to achieve the desired fabric tension and allow the fixing of extendable spacing bars therebetween.

Abstract: FLOATING CARRIER RETENTION  FOR A PLANETARY GEARSET       Abstract of the Disclosure A planetary gear system within a vehicle wheel has a sun gear at the wheel axis driven by a fluid motor and further includes a ring gear secured to the wheel rim.          Planet gears, engaging both the sun gear and ring gear, are mounted on a carrier which is revolvable as the planet gears orbit around the sun gear while transmitting drive from the motor to the wheel with a speed reduction and a correspond-ing torque amplification.  The carrier is not tightly restrained in either the radial or axial direction enabling positional self-adjustment to relieve stress concentrations at gear teeth.  Limits for the axial and radial play of the floating carrier are fixed by positioner means defining an annular groove into which the radially innermost edge of the carrier is loosely received, thrust bearing means such as thrust pins or annular thrust rings being situated within the groove at each side of the carrier edge.  Situating the positioner means at the minimum diameter portion of the carrier minimizes friction, wear, power dissipation and heating as that portion of the carrier turns at a smaller velocity than the more outward portions of the carrier.

Title: Apparatus for identifying faulty diodes in automotive  alternators
Inventor: MUELLNER FRANK J
IPC: G01R31/34
Filed: 1978-01-13
Granted: 1981-03-24
Abstract: ABSTRACT OF THE INVENTION      Faulty alternator diodes are identified by detection of a voltage ripple across the terminals of the automotive storage battery.  A diode is forward biased whenever the battery has adequate charge to be designated a "good battery", and the forward bias condition is utilized as a reference potential.  A voltage divider scales the reference potential, and couples it to the inverting terminal of a comparator.  The non-inverting terminal is biased at a predetermined differential from the inverting terminal, and the probe signal is AC coupled to the non-inverting terminal.  If a diode is bad, the superposition of the AC with the bias will switch the comparator and en-ergize a light emitting diode.

Abstract: ABSTRACT OF THE DISCLOSURE           A drive having a plurality of thrust bearings includes a rotatable shaft located in a housing with a space therebetween and a plurality of spaced apart thrust bearings in said space.        Two members axially movable with respect to one another are provided in the space between each pair of thrust bearings. A circumferential chamber is provided between the members with a resilient ring in the chamber. The volume of the ring is less than that of the chamber when little or no load is present. Under load the ring is deformed as the volume of the chamber is decreased due to axial movement of the members with respect to one another so that better distribution of the load between bearings occurs.
