Abstract: CONTROL OF RADIAL DISTRIBUTIONS IN HIGH INTENSITY DISCHARGE LAMPS                 Abstract of the Disclosure In a high pressure arc discharge lamp including one or more vaporized metal species, the radial distribution of metal atoms is controlled through the addition of a select amount of metal halide. In particular, in high pressure sodium lamps the density of sodium atoms near the arc tube wall is controlled through the addition of sodium iodide to reduce self-absorption of the plasma radiation by the sodium atoms.

The essence of this T-shaped tube is that the sleeve exhibits, in the vicinity of the flange, on the outside, a wide annular recess, the outer edge of the flange being curved back axially and forming a flat groove.  The annular recess and flat groove, at the edge of the flange, are filled by injecting a caoutchouc mix which is still vulcanizable.

Abstract: ABSTRACT           The inclination of the seat and back rest of an adjustable office chair can be varied and locked in a desired position.  A clamping bolt arrangement consists of a set of plates with friction discs on each side of each plate.  A bolt extends through the plates and friction discs and the assembly is supported in the seat carrier for free axial movement.  An eccentrically mounted lever, which is self-locking in either position, controls the tension on the bolt and hence the locking of the plates.  Since the lever requires only a short path of travel the assembly is suitable for mass production.

Abstract: TWO SPEED AXLE SHIFT ACTUATOR                 Abstract of the Disclosure A low power electric motor slowly load to spring, which rapidly operator a two speed axle shift. An electric motor drives a nonreversing worm gear which engages a gear rack on a shaft.          The shaft supports a caged spring.  The motor moves the shaft, compressing the spring against one end of the cage, storing energy required for shifting.  A solenoid piston holds the cage in position.  When the shift is desired, the solenoid is tripped, the piston is raised and the spring moves the cage.  An arm on the cage moves the shift lever.  The solenoid piston engages the opposite detent in the cage and holds the cage in the new position.  As the cage arrives at the new position, a lug trips a microswitch which completes a circuit to operate the motor in the reverse direction.  The motor worm slowly drives the gear which slowly drives the rack to move the shaft in the reverse direction, compressing the spring against the opposite end of the cage.  When the shaft moves sufficiently to fully load the spring, a lug on the shaft trips the switch turning the motor off.  The next pulsing of the solenoid causes the spring to drive the cage in the opposite direction, back towards its first position, where the solenoid locks the cage.  A lug in the cage trips the switch, turning the motor on to run in a forward direction, driving the shaft to its original position and compressing the spring until a lug on the shaft engages a switch, turning the motor off.

Abstract: METHOD AND APPARATUS FOR IMPLEMENTING        A THERMODYNAMIC CYCLE USING A FLUID OF CHANGING CONCENTRATION                          ABSTRACT      A method and apparatus for implementing a thermo-dynamic cycle involves utilizing partial distillation of a multi-component working fluid stream.  At least one main enriched solution is produced which is relatively enriched with respect to the lower boiling temperature component, together with at least one lean solution which is rela-tively impoverished with the respect of lower boiling temperature component.  The main working fluid is expanded to a low pressure level to convert energy to a usable form.  This spent low pressure level working fluid is condensed by dissolving with cooling in the lean solution to regenerate an initial working fluid for reuse.  A portion of the impoverished fraction may be injected into the charged gaseous main working fluid in order to obtain added work and to increase system efficiency by decreasing the temperature of the output fluid flow when the fluid flow would otherwise have been superheated.  A low pres-sure, low temperature expanded spent fluid may be distilled using low quality heat to create an enriched solution which has a significantly higher concentration of the lower boiling component.  For this enriched solution, a reduced temperature and pressure is sufficient to enable distillation.  The efficiency of the cycle may be enhanced by charging the spent fluid with the lower boiling temper-ature component prior to distillation.  This may be accomplished by lowering the pressure of the improverished fraction to separate an additional lower boiling tempera-ture fraction.
