Abstract: An approach (10) is provided as a way of obtaining useful power from a fusion reaction utilizing light weight isotopes of hydrogen and helium. A potential well is created between two accelerating electrodes (26) that, in a vacuum, allows ions from sources (24) to be captured by the potential well. An axial magnetic field as created by solenoid (20) causes the captured ions to pass through an ion focusing region (22) and thus allowing fusion reactions to take place within the region. The magnetic field also confines the trajectory of the fusion products (18) to a series of helixes preventing them from reaching the solenoid walls, but instead forces them to exit the two ends of the solenoid. Useful power is obtained by allowing two heat exchangers to intercept the fusion ions and thereby allowing a coolant liquid to be heated as would be required to operate a steam turbogenerator.

Abstract: Optical elements (52, 54) are bonded to supports (58) by a resilient bonding agent (68) and a rigid bonding agent (78). The resilient bonding agent has the property of shrinking upon curing and is placed within a bonding space (66) defined by rails (64) of a rail assembly (56). Upon curing, the bonding agent shrinks and securely pulls the contacting surfaces (52b, 64a) of the element and the rails under tension of the bonding agent. A donut (80) of resilient material spaces the bonding agent from contact with or adjacent to the contacting surfaces (64a, 52b) so that, for a rail assembly and an optical element of significantly different coefficients of thermal expansion, temperature variations will not cause glass pieces to be pulled from the optical element. The base (62) of the rail assembly is also made thin to bend and provide relief upon contraction of the bonding agent rather than to unduly stress the optical element.

Abstract: An optical element (10) is bonded to a support (12) by a resilient bonding agent (20). The bonding agent has the property of shrinking upon curing. It is placed within a bonding space (18) defined by rails (14, 16). Upon curing, the bonding agent shrinks and securely pulls the element against top surfaces (14a, 16a) of the rails under tension of the bonding agent.

Abstract: A cryogenic cooler (10) includes a dewar (14) spaced from a cold finger (12). In the space (18) between the dewar and the cold finger, a trace amount of a noncondensable gas, preferably neon, is added to the air to maintain the thermal conductivity between the cold finger and the dewar and thereby to prevent temperature cycling in the cooler.

Abstract: A method of adjusting the weight distribution of a locomotive having a pair of interchangeable 3-axle asymmetrical truck assemblies comprising loading the locomotive body with its normal supply of fuel, water, etc.

Abstract: A fingerprint inking apparatus, incorporating a self-contained supply of ink and a drive means that automatically produces a uniform film of ink of the correct thickness, on a thin elastic membrane, in preparation to the taking of rolled fingerprints. The membrane is supported on a compressible foam structure or between two rollers such that a downward pressure of the finger causes the membrane to form around the finger, thereby transferring the ink to the finger.

Abstract: Disclosed are a method and apparatus for liquefying chlorine out of a gas mixture containing chlorine gas and noncondensable gases. According to the disclosed method, a multi-stage compression means is utilized for the gas mixture. The gas is compressed as it passes through the compressor series, and then it passes from the last compressor of the series to a condenser. Liquid chlorine and a second gas mixture, containing larger amounts of non-condensables, are recovered from the condenser. A bleed stream of the liquid chlorine is utilized as a refrigerant for the second gas mixture and is passed through a series of individual economizers co-current to the second gas mixture. The flow of the chlorine refrigerant and of the second gas mixture in the economizers may be countercurrent or co-current to the flow of chlorine gas in the compressors.
