Title: Clock holdover circuit
Inventor: JOHNSON STEVEN D
IPC: H04L7/08
Filed: 1989-01-24
Granted: 1992-02-18
Abstract: ABSTRACT OF THE PRESENT INVENTION The present invention provides a clock holdover circuit which will provide a replacement clock signal within predetermined parameters independently of time and temperature variations. The circuit of the present invention has only a single component which is time and temperature dependent. By selecting the components parameters to be within the desired tolerances, the accuracy of the circuit is maintained. In the present invention, digital circuitry is combined with an accurate local crystal frequency source to provide a replacement clock signal. The present invention allows phase consistency upon loss of a reference clock signal as well as on return of the reference clock signal. A reference clock signal is phase locked to a VCO to produce a desired output. The frequency of the output is compared to a local frequency standard to generate an offset frequency used to control a frequency synthesizer. The offset frequency is digitally stored. Upon loss of the reference clock signal, the stored offset frequency is used to drive the frequency synthesizer along with the local frequency standard so as to provide an acceptable replacement clock signal. The frequency comparator, storage, and synthesizer are all digital so as to be time and temperature independent. The local frequency standard is crystal based having known time and temperature tolerances. By choosing a local frequency standard having tolerances within a predetermined range, an acceptable clock holdover signal may be provided indefinitely. The replacement clock signal is phase compared to the reference clock signal so that no loss of phase occurs upon reference loss.

Abstract: TITLE OF THE INVENTION            METHOD FOR ENHANCING THE POLYMERIZATION ACTIVITY OF CRUDE CYCLOOLEFIN MONOMERS FOR BULK POLYMERIZATION                    ABSTRACT     A process for enhancing the polymerization activity of mixtures of one or more cycloolefin monomers is provided by treatment with heat. This process can be easily incorporated into ring-opening, bulk polymerization methods and methods which form high molecular weight monomers. Enhancing the polymerization activity of crude mixtures of cycloolefin monomers by this process permits polymers having higher glass transition temperatures and higher heat distortion temperatures to be produced with greater economy.

Title: Air conditioning process and apparatus therefor
Inventor: RYHAM ROLF
IPC: B01D53/26

Granted: 1991-01-29
Abstract: ABSTRACT An air conditioning process and apparatus includes absorption of water vapor in a circulating absorption liquid composed of an aqueous salt solution. The absorption liquid is  regenerated by evaporative concentration by indirect heat exchange with a heating fluid in an evaporator.  The water vapor produced in the evaporator is condensed in a condenser by indirect heat exchange with a cooling liquid which is mainly composed of the absorption liquid to be concentrated or which has already been concentrated in the evaporator.   The water vapor pressure over the cooling liquid in the condenser is lowered by causing gas to flow in contact with the cooling liquid.

Abstract: Abstract The guardrail window assembly includes a window sub-assembly movable between the floor and ceiling sections of a patio or balcony.  A stationary support is mounted on the floor and includes two foreshortened vertical supports rising only partially towards the ceiling section.  A crossheader frame is movably retained between the two vertical supports. The crossheader frame is generally rectangularly shaped and the sides of the crossheader carry trolleys that run in tracks provided within the stationary support.  In a first position, the crossheader frame is encased by the stationary support.  In a second position, the crossheader frame extends from and frames an area between the stationary support and the ceiling.  That area can be open or can be screened, as necessary.  A window, consisting of a window pane and a window frame, is movably retained within the crossheader frame and the stationary support.  In the first and second positions, the window is disposed within the stationary support.  In a third position, the window is encased by the crossheader frame and therefore closes the framed area.  The guardrail window assembly also includes a motor and a pulley drive system for moving the crossheader frame and the window sequentially through the first, second and third positions with respect to the stationary support.

Abstract: ABSTRACT OF THE DISCLOSURE      A radio telephone apparatus, such as a car telephone, and the method of controlling a radio telephone apparatus in which the OFF operation of a power source switch caused by an erroneous operation is inhibited when the radio telephone is in a talk mode.  In more detail, the ON or OFF state of the power source switch is detected as well as whether or not the apparatus is in the talk mode, so that the switching of a power source line switch to its OFF state by means of the power source switch is inhibited in the talk mode and allowed only in a non-talk mode.  Further, an ON/OFF function of a power supply of the apparatus as well as, for example, a muting function which is necessary only in the talk mode and which acts to attenuate a transmission talk voice, are allocated to one of keys in a dial keypad.  The ON or OFF state of the allocated function key is detected to perform muting control based on the ON or OFF output of the function key in the talk mode and to perform ON/OFF control of the apparatus power supply in the non-talk mode.
