Title: Microwave absorber attenuator for linear sspa power control
Inventor: MCGANN WILLIAM E
IPC: H03G3/20
Filed: 1988-05-03
Granted: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE    The nonlinearity of the frequency response of a solid state power amplifier (SSPA) is obviated by effectively operating the SSPA at the ldB compression point, where the nonlinearity does not exist, and controllably reducing, downstream of the SSPA, the power output produced by the SSPA to the level required by the link.  In particular, the output is reduced by controllably inserting a relatively thin tapered blade of ferrite material into a waveguide coupling section downstream of the SSPA.  Preferably the ferrite material is comprised of a robust carbonyl steel of sufficient thickness to withstand the heat induced in the course of its absorbing microwave energy at the SSPA output, while being of a narrow or thin configuration and oriented for insertion into the absorbing section of waveguide so as to not effectively alter the characteristics of the signal profile of the electromagnetic wave.

Abstract: Abstract Controlling Oxygen Concentrations in Fuel Cell Cooling Water Loops In order to achieve good stack water chemistry and minimize corrosion in a fuel cell stack water cooling loop, the oxygen concentration in the water must remain within a relatively narrow range.  Stacks using steam separators produce water in the separators which is relatively devoid of oxygen.  Makeup water is used to replace the steam lost from the separator, which makeup water is relatively rich in oxygen.  The flow rates of the makeup water and steam separator water are controlled to produce a proper oxygen concentration in the recirculated coolant water.  Some of the makeup water will be added directly into the steam separator so that it will be stripped of oxygen and the rest will be added subsequent to the steam separator.

RMn) are transmitted bilaterally between at least one each of a portable transmit-receive unit (17), a stationary transmit-receive unit (22a) and a control (43).  The portable transmit-receive unit (17) contains a microprocessor (51) and is for example carried in the hand or in a clothing pocket.  In that case, control commands are put in anew each time according to the frequency of their occurrence by way of a decade keyboard (ZO ....          Zg) or by way of fixed keys (F1 .... Fn) or kept in reserve in a store (59) and sent out by means of the operating mode selector switch (54) as control signals (SS1 .... SSn) selectably in the operating modes "manually on pressing a button" or "automatically, permanently".  The signalling is not public and takes place on the indicator (57). The stationary transmit-receive unit (22a) with microprocessor (62) is mounted stationarily in the transmitting range of the associated portable transmit-receive unit (17) and communicates the received control commands to the control (43).  This remote control makes a location-independent input of public and non-public operating requests possible in lift installations and thereby a conveniently and secure call issue to protected storeys.  Method and equipment are equally applicable also to the operation of doors, escalators, turnstiles and so forth and accordingly are suitable generally for the checking of the access and for the easing of the personnel traffic in buildings.
