Abstract: LOCKING DIFFERENTIAL MECHANISM   WITH IMPROVED HOLDOUT RING     AND SPRING RETAINER            ABSTRACT OF THE DISCLOSURE         An improved differential mechanism of the holdout ring type is disclosed, characterized in that the annular holdout rings are mounted concentrically between the driven clutch members and the associated side gears, respectively, and the springs biasing the driven clutch members toward engagement with the driving spider member arranged therebetween includes a pair of compression springs mounted concentrically between the holdout rings and the side gears, each spring reacting at opposite ends between the associated side gear and annular spring retainer member, respec-tively.  Furthermore, the driven clutch members are each provided with only one set of uniform teeth which cooperate both with driving teeth on the spider member and overrunning clutch-disen-gaging teeth on the center cam member.  Consequently, a compact durable positive differential mechanism is provided that is of relatively simple, inexpensive construction requiring  a minimum number of parts.

Abstract: ABSTRACT A method and apparatus for acceleration limiting a gas turbine engine (10) is disclosed.  A proportional fuel control (11) regulates the fuel flow Wf from a hydromechanical unit (36) based upon an error signal E representing the difference between a demanded speed signal Nd and an actual speed signal Ng.  The demanded speed signal Nd is generated by an integrator (32) as the time integral of the difference between the demanded signal Id and a scheduled speed signal Ngs.  Additionally, the difference signal is limited between an upper limit Al and a lower limit D1 prior to the integration by a comparator (28) and a limiter circuit (30).  The acceleration limit, Al is generated as a function of a nondimensional parameter ratio (dN/dt X N)/Wf.                         (Figure 1)

Abstract: IMPROVED SHOWER     Abstract Of The Disclosure For a shower for a household, dormitory or the like, which typically has a limited volume of boiler-heated water available for use, the cold water input to the shower is passed in heat exchange with the discharging tepid water to thereby convert same to a lukewarm water source, the temperature change being typically a 15 to 25 degree rise,whereby significantly less boiler-heated water is required for preparing a suitable tepid water mixture comfortable for showering.  The aforesaid significantly prolongs the showering service use of the system and, since less boiler-heated water is consumed, correspondingly lessens the fuel consumption of the boiler.

Abstract: ABSTRACT In a conventional frequency synthesizer used for a frequency modulation trans-ceiver, a reference oscillator feeds a reception oscillator and a transmission oscillator, each of which has a phase locked loop (PLL).  Each PLL includes a voltage controller oscillator (VCO), variable frequency divider, phase com-parator and low pass filter.  The dividing ratio of each frequency divider is varied with a channel designation signal and a modulating signal is applied to the VCO of the transmission oscillator together with a control voltage representative of the frequency difference between the VCO output and the reference oscillation.  To overcome instability inherent in this system the invention takes a portion of the modulated carrier wave demodulates it and adds it to the modulating signal in reverse phase to achieve negative feedback.

Abstract: ABSTRACT    A process is dislosed for rejecting nitrogen from a natural gas feed containing nitrogen over a wide range of compositions, e.g. 5-85% nitrogen by volume, under elevated pressure using a single distillation column and a closed loop methane heat pump which reboils and refluxes the column.  An intermediate reflux condenser is refrigerated by both the heat pump and overhead nitrogen fraction from the distillation column.  The process can handle feeds with increasing nitrogen content and more than 100 ppmv carbon dioxide.  The feed can be at pipeline pressure with the natural gas liquid components still present or at lower pressure with natural gas liquids removed.  A mixed cryogenic refrigerant can be used in the heat pump as an alternative to methane.  The process provides a high methane recovery over the entire feed range, and provides a nitrogen product stream having an elevated pressure suitable for recycling and reinjection to an oil or gas well to improve well head pressure.
