Title: Heavy duty friction clutch
Inventor: YANKO JOHN P
IPC: F16D13/38
Filed: 1986-12-15
Granted: 1991-01-02
Abstract: Title: Heavy Duty Friction Clutch Abstract of the Disclosure A friction clutch wherein the mechanical advantage or lever ratio can be varied without changing the construction of the release levers.  This is achieved by changing the location of the pivot pins that connect the levers to the pressure plate, and by elongating the release lever holes through which the pivot pins pass.  Changing the location of a pivot pin with respect to its supporting lugs on the pressure plate will cause a change in the location of the pin along the length of the elongated pivot pin holes in its corresponding release lever, and this in turn operates to change the mechanical advantage exerted by the lever on the pressure plate.

Title: Optical device

Filed: 1988-03-28
Granted: 1991-12-31
Abstract: OPTICAL DEVICE"     Abstract An optically bistable device 100 is disclosed having a self electro-optic effectdevice (SEED) 104 and a variable optical attenuator 103 for maintaining the state of the SEED over a wide power range of two input light beams. The SEED is responsive to the relative power levels of the two input light beams for assuming one of two states. The state of the SEED is determined by the transmission levelof one of the beams passing through quantum well region 102 of the device. The variable optical attenuator concomitantly varies the power level of the two input beams to maintain the present state of the SEED over a wide range of input lightbeam powers. When operated in a bistable operating region of the device, a control light beam with a low power level changes the device from one state to another. Two threshold values of a ratio of power between the two input beams establish where the device switches from one state to the other.

Title: Wide range gaseous fuel combustion system for gas turbine engines
Inventor: SOOD VIRENDRA M
IPC: F02C9/40
Filed: 1988-04-07
Granted: 1992-09-08
Abstract: Abstract of the Disclosure Wide Range Gaseous Fuel Combustion System for Gas Turbine Engines Systems capable of supplying either all gaseous fuel, all liquid fuel, or a mixture of the two, at a preselected ratio have been successfully employed in gas turbine engines.  The mixing of such fuels has taken place in the combustion chamber and has caused the nozzle design and system controls to complicate the structure and increase costs.  The subject system for burning gaseous fuels having a range of calorific values has overcome these problems by providing a simple inexpensive system.  The system uses a starting step where only high calorific value gaseous fuel is injected through a first fuel supply passage of an injector and operates the engine to a preestablished engine operating parameter.  After the preestablished engine operating parameter has been reached a low calorific value gaseous fuel is mixed in a mixing chamber outside the combustion chamber and injected through the first fuel supply passage until a level of heating value of the mixed fuel or a second engine operating parameter has been reached.  The mixing continues and a second fuel supply passage of the injector is opened to increase the mass/volume flow of fuel into the engine.  The ratio of low calorific value gaseous fuel increases and the high calorific value gaseous fuel decreases as the engine operating parameters are monitored until the engine operates on only the low calorific value gaseous fuel.

Title: Temperature control system using a single ramp rate curve for control of a multiplant environmental unit
Inventor: BECKEY THOMAS J
IPC: G05D23/19
Filed: 1988-04-14
Granted: 1991-08-27
Abstract: ABSTRACT OF THE DISCLOSURE        A temperature control system for a multiplant environmental unit such as a heat pump with auxiliary heat is disclosed.  The control system utilizes a thermostat having a microprocessor and memory that allows for energy savings through setback functions. The setback functions return the temperature control from a setback temperature to a normal comfort temperature along a ramped rate that is modified from day to day. The purpose of this variable ramp is to minimize the operation of the auxiliary heat and maximize shell savings (by starting as late as possible).  This is basically accomplished by locking the heat pump on in certain cases.

Abstract: ABSTRACT OF THE DISCLOSURE          A diplexer  for  communicating  signals  in  two different frequency bands with separate polarizations in each  band may,  for  example,  concurrently  separate  low frequency  received  signals  of  orthogonal  polarizations from high frequency  transmitted signals, also  of orthogonal polarizations.   To this end a common square waveguide leads to serially disposed, axially displaced, orthogonal mode transitions at which branches are made to closely  coupled  lowpass  filters  that  communicate  with separate ports for low frequency signal bands.  A smaller square waveguide coupled to the second of the orthogonal mode transitions communicates with another orthogonal mode transition at which axially displaced branches communicate with other ports for high frequency signal bands.
