Patent number: 4914331Abstract: A dynamoelectric machine includes a rotor assembly and a stator assembly mounted between endshields. The endshields have axial and radial apertures to assist in motor cooling. A motor shaft extends through one endshield. A mounting plate is provided for mounting the motor. The shaft extends vertically downward through the mounting plate, to which the transmission of a machine also is mounted. A drive pulley is attached to the motor shaft and a driven pulley is attached to the transmission shaft. The pulleys are maintained in planar alignment to permit transfer of power between the pulleys and to minimize belt wear. A second endshield has a bearing housing design which provides a flush endshield surface facing upwards towards the bottom of the machine. Motor height can be varied by increasing stator assembly stack height between the endshields to the extent permitted by the overall space available between the flush surface of the one endshield and the bottom of the machine.Type: GrantFiled: August 2, 1988Date of Patent: April 3, 1990Assignee: Emerson Electric Co.Inventor: John G.

Patent number: 4354906Abstract: A combined radiolytic and thermochemical closed cycle process for production of hydrogen from water wherein H.sub.2 S is dissociated at high temperature and pressure by radiation, such energy being sufficient to provide dissociation and additionally to heat the reaction products to about 1100.degree. K. Hydrogen is separated from the radiolytic reaction products. The sulfur product is reacted with water in multiple additional thermochemical process steps for which heat of reaction is supplied by the radiolytic reaction products for reconstitution of the H.sub.2 S working fluid and generation of an oxygen byproduct.Type: GrantFiled: February 21, 1980Date of Patent: October 19, 1982Assignee: Texas Gas Transmission CorporationInventors: Henry J.

Patent number: 4304627Abstract: A piston is moved by a laser incited fusion reaction such as deuterium-tritium (D-T) to thereby produce an expandable fusion chamber. When a gaseous substance such as CO.sub.2 is presented in the presence of the fusion reaction, it is dissociated into CO and O.sub.2 component mixture and the expansion of the chamber rapidly cools the mixture and quenches the back reaction thereby producing a greater CO yield. Also the piston produces peripheral power from the fusion reaction in the form of mechanical energy.Type: GrantFiled: September 28, 1978Date of Patent: December 8, 1981Assignee: Texas Gas Transmission CorporationInventor: John G. Lewis

Patent number: 4284864Abstract: A low actuating force switch having one or more resilient switch arms cantilevered within a switch housing and further having an operating member or plunger movable within the housing for flexing the switch arm(s) and for making or breaking one or more circuits. A spring is interposed between the operating member and one of the switch arms for applying a force to this switch arm which in turn flexes the latter. In instances in which the switch arm is normally in an unflexed, open position and in which the operating member continues to move in the direction for closing the contacts after the contacts have closed, the spring takes up or absorbs a substantial portion of the additional movement of the operating member without exerting undue stress on the switch arm. In instances in which the switch contacts are normally closed, the operating member may engage the switch arm distal from its cantilevered connection to the switch housing so as to lessen the force required to open the contacts.Type: GrantFiled: January 26, 1979Date of Patent: August 18, 1981Assignee: Emerson Electric Co.Inventors: William D. Crow, John G. Lewis

Patent number: 4219245Abstract: A spherical bearing retainer which is adapted to be readily installed in the bearing hub of a dynamoelectric machine end shield or other suitable bearing support structure by forcing the retainer in an axial direction toward a spherical bearing member to be retained and by simultaneously twisting it within the hub. The retainer has a plurality of tabs engageable with inner surface of the hub with each of these tabs being disposed at a predetermined lead angle relative to the retainer so that upon twisting (or turning) of the retainer in the hub, the tabs "self-thread" the retainer into engagement with its respective bearing member and lock the retainer against movement away from its bearing member.Type: GrantFiled: April 11, 1979Date of Patent: August 26, 1980Assignee: Emerson Electric Co.Inventor: John G. Lewis

Patent number: 4144150Abstract: A source of neutrons is provided such as by a fusion reaction, and the neutrons are passed through a series of successive chambers in each of which a radiolytic chemical reaction takes place from bombardment of a sensitive chemical compound by said neutrons. The resulting products are further processed in a chemical reaction with a further compound such as water to release a desired end product such as hydrogen. The chemical reactions in the separate chambers may be selected to operate at different pressures or other physical conditions, and when pressure differences between the chambers are large stay structure is introduced to permit thinner walls more transparent to transmission of the neutrons from one chamber to the next.Type: GrantFiled: September 2, 1975Date of Patent: March 13, 1979Assignee: Texas Gas Transmission CorporationInventors: Henry J. Gomberg, John G. Lewis, Theodor Teichmann, Robert J. Teitel

Patent number: 4140602Abstract: The invention disclosed provides a new improved chemical method for combustible fuel production by converting carbon dioxide in the atmosphere to a carbonate following which the recovered carbonate is combined with hydrogen gas to produce combustible fuels e.g. methane and methanol. The present method provides means for fuel generation and may advantageously use heat and radiation energy derived from nuclear reactors.This application implies certain environmental advantages, in that burning of fuels containing carbon derived only from atmospheric CO.sub.2 would not add to the CO.sub.2 content of the atmosphere. Recycling of lime as CaO or Ca(OH).sub.2 would eliminate the problem of disposing of those materials as encountered by others teaching use of carbonates but not using such a closed cycle.Type: GrantFiled: March 30, 1976Date of Patent: February 20, 1979Assignee: Texas Gas Transmission CorporationInventors: John G. Lewis, Alfred J. Martin
