Title: Phase-locked loop frequency tracking device including a direct digital synthesizer
Inventor: SHAHRIARY IRADJ
IPC: H03L7/12
Filed: 1991-09-06
Granted: 1996-07-09
Abstract: Disclosed is a single phase-locked loop (50, 350) providing tuning over a very large bandwidth for use in wide band carrier tracking and clock recovery systems. In  a  first  embodiment,   a  DC  signal  is  formed representative of a phase difference between an input signal changing with time and a return signal.  The DC signal is applied to a narrow band voltage controlled oscillator (68) which converts the DC signal back to an AC signal.  The AC signal is level shifted to form a clocking pulse  for an accumulator  (80)  of a direct digital synthesizer (72).  A digital command word is also applied to the accumulator  (80),  such that the digital command word represents a coarse tuning of the input frequency.  The clocking pulse from the narrow band VCO  (68)  supplies a  fine tuning of the  input frequency.    In   a   second   embodiment,   the   DC representative   phase   signal   is   applied   to   an analog-to-digital  converter  (364)  which  produces  an N-bit word representative of the phase difference.  The change  in  phase  alters  the  digital  output  of  the analog-to-digital  converter  (364)  which  in  turn  is applied to the accumulator  (376)  of a direct digital synthesizer (370).  By this invention, very wide band tracking is capable with a single phase-locked loop, thus limiting the hardware and cost.

Title: Pump sprayable dispensing system for vegetable oil based pan coatings
Inventor: HANSON H WAYNE
IPC: B05B11/00
Filed: 1991-11-13
Granted: 1994-08-16
Abstract: ABSTRACT A nozzle assembly is interconnected with the delivery passageway or conduit from a hand pump sprayer. The nozzle assembly has a first and second passageway, preferably conduits, which are connected to the delivery passageway or conduit and split the fluid exiting from the delivery passageway or conduit into two streams. The cross sectional flow area of the first and second conduit means is smaller than the cross sectional flow area of the delivery conduit so that the velocity of the fluid increases upon entry into the first and second conduits located in the nozzle assembly. Each conduit has a fluid outlet to the atmosphere. The first and second conduits in combination with said fluid outlets define a discharge axis. The first fluid conduit discharge axis intersects the second fluid discharge axis at an impingement angle of from 10° to 170° so that the fluid exiting each outlet intersects at a point exterior to the nozzle. As a result the fluid exiting the first outlet collides with the fluid exiting from the second outlet to break the fluid into small droplets to form a wide angle mist. The nozzle assembly is particularly useful for spraying viscous pan coatings containing vegetable oil.

Title: Frequency modulated synthesizer using low frequency offset mixed vco
Inventor: HECK JOSEPH P
IPC: H03C3/09
Filed: 1991-08-16
Granted: 1995-04-11
Abstract: An improved frequency synthesizer (100) capable of producing true DC frequency modulation without the need to DC fre-quency modulate the reference oscillator. The synthesizer (100) includes a phase comparator (104) which compares the reference signal (102) and the feedback signal (112). The output of said phase comparator (104) is filtered and coupled to the main VCO (108). A balanced image mixer (200) mixes the two signals from the main VCO (108) and an offset VCO (300). The offset VCO (300) is a low frequency (e.g. 100 to 300 KHz) integrated offset VCO (308) whose center frequency is controlled accurately, by means of matching to a VCO (306) which is controlled by a feedback loop, and by using an image balanced mixer (200) to reduce the image response to substantially reduce or eliminate the filtering required at the mixer output. The configuration of the offset mixer within the synthesizer loop, any residual spurious content due to imperfect image balance or carrier feedthrough of the mixer is attenuated by the loop response. The output signal of the mixer (200) is looped back to the phase comparator (104) after being divided by N through a divider (114).
