Abstract: An articulated bearing has an inner ring with a spherical outer surface, and an outer ring with a hollow spherical inner surface corresponding to and engaging the outer surface of the inner ring. Plastic bearing segments are circumferentially arranged in the cylindrical bore of the inner ring. The plastic segments are held by rings having inclined ends engaging the ends of the plastic segments. Circumferential displacement of the segments is prevented by strips affixed in the bore of the inner ring between adjacent segments. The plastic segments extend radially inwardly of the holding rings and strips a distance, in the absence of loading of the bearing, corresponding to the elastic deformation of the segments in the loaded condition. A pin in one of the inner and outer rings is urged into a recess in the other of the inner and outer rings, by means of a spring.

Movable, essentially identical mold carriers are provided with article-related mold inserts preselected for the work cycle and locked in place in the carriers. The forming tool is filled with the synthetic, it is exposed for a given time to certain temperature and pressure conditions, the tool is opened and the inserts are expelled. The form carriers are then outfitted with another set of form inserts while the first set of mold inserts are removed from the molding cycle.

Abstract: An electric power plant having dual turbine-generators connected to a steam source that includes a high temperature gas cooled nuclear reactor. Each turbine comprises a high pressure portion operated by superheat steam and an intermediate-low pressure portion operated by reheat steam; a bypass line is connected across each turbine portion to permit a desired minimum flow of steam from the source at times when the combined flow of steam through the turbine is less than the minimum. Coolant gas is propelled through the reactor by a circulator which is driven by an auxiliary turbine which uses steam exhausted from the high pressure portions and their bypass lines. The pressure of the reheat steam is controlled by a single proportional-plus-integral controller which governs the steam flow through the bypass lines associated with the intermediate-low pressure portions.

Abstract: A power plant including dual steam turbine-generators connected to pass superheat and reheat steam from a steam generator which derives heat from the coolant gas of a high temperature gas-cooled nuclear reactor. Associated with each turbine is a bypass line to conduct superheat steam in parallel with a high pressure turbine portion, and a bypass line to conduct superheat steam in parallel with a lower pressure turbine portion. Auxiliary steam turbines pass a portion of the steam flow to the reheater of the steam generator and drive gas blowers which circulate the coolant gas through the reactor and the steam source. Apparatus and method are disclosed for loading or unloading a turbine-generator while the other produces a steady power output. During such loading or unloading, the steam flows through the turbine portions are coordinated with the steam flows through the bypass lines for protection of the steam generator, and the pressure of reheated steam is regulated for improved performance of the gas blowers.

Abstract: An electric power plant having a cross compound steam turbine and a steam source that includes a high temperature gas-cooled nuclear reactor. The steam turbine includes high and intermediate-pressure portions which drive a first generating means, and a low-pressure portion which drives a second generating means. The steam source supplies superheat steam to the high-pressure turbine portion, and an associated bypass permits the superheat steam to flow from the source to the exhaust of the high-pressure portion. The intermediate and low-pressure portions use reheat steam; an associated bypass permits reheat steam to flow from the source to the low-pressure exhaust. An auxiliary turbine driven by steam exhausted from the high-pressure portion and its bypass drives a gas blower to propel the coolant gas through the reactor.

Abstract: A clutch connects the drive motor to the rotatable tool holder. The driven part of the clutch has a plurality of clutch recesses bounded by sloping clutch ridges, with clutch balls received in the recesses. An annular pressure body surrounds the driving part and is pressed by a threshold-torque-determining spring against the clutch balls to hold them in their recesses. When the clutch torque exceeds the threshold value, the clutch balls rise out of the clutch recesses and slip over the respective clutch ridges into the respective adjoining clutch recesses. In so doing, they briefly push back the annular pressure body. This causes the annular pressure body to drive locking balls radially inward through registering radial openings in the driving part and in a locking bolt interior to the latter. When the inner locking ball moves completely into the locking bolt, locking between the driving part and locking bolt terminates.

Abstract: A drilling tool consists of a drill and a tubular shaped receiving part fitted onto the trailing end of the drill. The outer surface of the receiving part is shaped to fit into the chuck or retainer of a drilling device which rotates the drill. The inner surface of the receiving part and the juxtaposed surface on the trailing end of the drill are in locking engagement, however, under certain torque conditions the locking engagement will be released so that the receiving part can rotate relative to the drill. Preferably, the locking engagement is established by deflectable projections formed on at least one of the receiving part and the drill which seat into recesses formed on the juxtaposed surface of the other. Passageways are provided between the trailing end of the drill and the receiving part.

Abstract: Stack gas is first passed through a coarse-particle separator and then a prescrubbing tower. Then this gas, which is under pressure, is passed through a pair of Venturi washers. The output side of one of the washers is connected directly to a droplet separator at the output of the system. The outlet of the other Venturi washer is connected through a turbine driving an electric generator and having its output side in turn connected to the droplet separator. The control body of at least the washer which is connected directly to the droplet separator is adjustable so as to maintain a constant back pressure in the system at the blast furnace from which the stack gas comes. The Venturi washer connected to the turbine is set up to pass at least four times as much of the gas as the other Venturi washers so that most of the gas passes through the turbine, undergoing a pressure drop that is transformed into the work of driving the turbine and generates electricity.

Abstract: Measurements of physical attributes such as dielectric film thickness that are susceptible to spectral analysis are accomplished rapidly and accurately by a spectrophotometric system in which a programmed digital computer operating concurrently with the optical scanning means automatically performs the calibrating, normalizing and data reducing functions that otherwise must be carried out as time-consuming human, mechanical or analog electronic operations. The control over the optical data handling operations exercised by the computer eliminates the need for mechanically or electronically adjusting the optical apparatus to meet changing system conditions, whether periodic or aperiodic.
