Abstract: A grinding device for grinding the end surfaces of articles, such as cylinders or rings, comprises, first and second grinding discs which are mounted in spaced apart relationship by an amount substantially equal to the distance between the ends of the articles to be ground and with their axes offset from each other by a spacing therebetween so that the discs define an overlapped space therebetween having an entrance apex at which the area of overlap begins and an exit apex at which the area of overlap ends. The discs are rotated in respective opposite directions and the articles are delivered into one apex, such as the entrance apex, and the rotation and speed of the discs are such that they are urged by the discs to move toward the opposite or discharge apex where they are separated from the discs. The angular speeds of the two grinding discs determines the path of the workpieces through the overlapped zone between the discs.

Abstract: A case packing machine is described for bottles having enlarged neck flanges. The machine first arranges bottles received from a conveyor into a group on an escapement mechanism. The grouped bottles are suspended from their enlarged neck flanges by an escapement mechanism at a first station.

Bottles may be received by an invertible holder at the second station. The holder forms the bottles into a prescribed rectangular array and supports the bottles until a subsequent group is received. The subsequent received group engages and moves the first group downwardly into a case waiting at a packing station below.

Abstract: PCT No. PCT/US 79/00843 Sec. 371 Date Oct. 15, 1979 Sec. 102(e) Date Oct. 15, 1979 PCT Filed Oct. 15, 1979 A combination rotating fluidized bed combustor and rotating fluidized bed heat exchanger particularly adaptable as the combustor and heat exchange unit, respectively, of conventional gas turbine engines is preferably arranged with the combustor nested within the heat exchanger for maximum compactness.

Abstract: Ion chamber 20 receives electrons from cathode 28 and produces ions by electron bombardment in discharge plasma chamber 20. Ions are extracted through ion optics including screen 22 and accelerator electrode 24. Higher ion densities in the center of the discharge chamber are reduced by spoiler 42 which is operated at a potential between cathode and anode potential. This reduces double ionization and central peaking to provide a more uniform ion beam through the optics. By employing laterally positioned spoiler elements beam steering can be accomplished. The ion source is useful wherever a uniform beam profile is desirable as in ion implantation. Controlling the direction of beam density is useful in ion machining and in ion thrusters for space application.

Abstract: In an integral rocket-ramjet having a combustor which initially serves as a rocket combustion chamber for booster propellant, and after the booster propellant is expended serves as a ramjet combustor where fuel and air are burned, a fuel control system is described for the ramjet stage by which ram burner light-off is automatically initiated upon transition from rocket to ramjet propulsion. The fuel control regulates fuel flow to the combustor over the entire flight regime and responds to operating conditions to provide a light-off schedule, to stabilize the shock wave at the air inlet, to provide a maximum fuel-to-air ratio limit, to limit the maximum vehicle Mach number, and to prevent lean burner blowout by providing a minimum fuel-to-air ratio limit. Mach number limiting and air inlet margin limiting are performed in closed loop fashion, while the other functions are scheduled or open loop controls.

The annular ejector includes an annular plate with radially-directed flow passages to provide an even distribution of the air/exhaust gas mixture to the burner region.

Abstract: A method and apparatus for supplying superheated steam at desired temperatures and pressures to a steam turbine. First source steam from a boiler steam drum passes through a control valve to form regulated steam which is conducted through a heat exchanger where a portion of it is condensed. The partially condensed regulated steam exhausted from the heat exchanger is throttled by a throttling valve to a lower pressure to form control steam and the vapor therein is separated from the liquid. The vapor is transmitted through the heat exchanger and absorbs heat from the regulated steam also passing therethrough. Cooperative adjustment of the control valve and throttling valve permits gradual adjustment of the control steam's temperature and pressure leaving the heat exchanger. When the control valve is completely open, the temperature of the control steam leaving the heat exchanger is a maximum which cannot be increased by further manipulation of the control and throttle valves.

Abstract: A method and apparatus for converting high pressure, high temperature elastic fuild (such as steam) to elastic fluid having a desired relatively low pressure and low temperature. Relatively high pressure, high temperature steam supplied from any point (preferably from a steam drum or equivalent location) in a steam cycle is initially throttled from a high temperature and pressure to a relatively intermediate temperature and pressure. Such intermediate temperature and pressure steam is routed through the tube side of a heat exchanger and subsequently throttled to a relatively low temperature and pressure. The resulting low temperature and pressure steam is then separated into its liquid and vapor phase components wherein the vapor phase is transmitted through the shell side of the heat exchanger and absorbs heat from the intermediate pressure, and temperature steam. The relatively low pressure, low temperature steam exiting the heat exchanger has the desired thermodynamic state.

Abstract: A spline drive arrangement has two externally-splined shafts, which engage an internally-splined gear. An extension on the shaft is a relatively close fit in a bush which lines a bore in the shaft. The drive arrangement is maintained full of liquid which can enter and leave a space in the bore by way of restricted passages and a clearance zone between the extension and bush. Damping and viscous drag of the fluid tends to prevent relative movement, between the splines of the shaft and gear, which may occur if the torque load on the shaft is low.
