Title: System and method of frequency calibration in a linked compression-expansion (lincompex) system
Inventor: LEVEQUE JAMES H
IPC: H04B1/64
Filed: 1990-06-04
Abstract: A linked compressor-expander  (Lincompex)  circuit for  use  in  telecommunications  utilizes  a  frequency compensation  circuit   to   frequency  shift  the  total bandwidth of the whole communication channel to eliminate single side band "duck-talk" and data distortion in the transmitting of a complex waveform due to frequency drift or  the detuning of the transmitter/receiver system. The demodulator  includes  an  expander  for  expanding  the compressed  voice  or  data  signal  and  a  control  tone conversion  circuit  for  converting  the  received  control tone into a frequency signal to be used by the expander. The control tone conversion circuit  also determines  the frequency error of a combination information waveform so that the frequency compensation circuit can carry out the proper frequency shifting process. A fading regulator is also provided to remove any audible level variations not removed by the  automatic  gain control circuitry in the receiver.

Patent CA-2031885-A1 (CA)
Inventor: APTER ROBERT
IPC: G01N21/90
Filed: 1990-12-10
Abstract: A conveyor moves the hollow bodies over a circular path through an inspection region in which the hollow bodies are homogeneously illuminated by an illumination device. The light issuing from the hollow bodies passes via a group of four mirrors and a deflecting mirror to a matrix camera or line scanning camera.  The mirrors are plane mirrors which are inclined at an angle in relation to one another. The hollow bodies execute one complete revolution about their longitudinal axis while passing through the inspection region.   Therefore,  the group of four mirrors views a quarter of the circumference of the hollow bodies each time in succession.  The inspection apparatus is particularly suitable for inspecting the threaded region of bottles and has the advantage that it does not need any moving parts.

Title: Mmic gain element with accurate gain
Inventor: JACOMB-HOOD ANTHONY W
IPC: H03G9/24
Filed: 1991-01-17
Abstract: MMIC GAIN ELEMENT WITH ACCURATE GAIN              ABSTRACT OF THE DISCLOSURE    The invention consists of a novel combination of an MMIC gain element whose gain (S21 magnitude)  is subject to departure from a desired constant value over a given frequency spectrum and a passive gain correc-tion network for restoring the gain to said desired constant value without causing increases in the input (S11) or output (S22) reflectance or non-linearity in the phase (S21 phase).   The passive gain correction network utilizes a pair of 90° hybrids, the first in a power division configuration, and the second in a power summation configuration.  The two hybrids are inter-connected by two filters, which depending upon the nature of the departure being corrected may be alike or dissimilar.   The use of hybrids with appropriately selected filters facilitates correction of the S21 magnitude in a large variety of forms (e.g. ripple, slope, excess gain) without the customary worsening of the other transfer functions.   The passive gain correction network may be of a stripline/microstrip format.  The invention has application to the modules used repetitively in large numbers in antenna arrays and is intended to facilitate module interchange ability in a cost effective manner.

Abstract: END PLAY AND PRELOAD ADJUSTING ASSEMBLY         FOR TAPERED BEARINGS            ABSTRACT OF THE DISCLOSURE         An assembly (10) by which to effect incremental adjustments to the end play, or preloading, to a bearing set (12).  Relatively rotatable first and second ring means (25 and 35) have contiguously juxtaposed and interacting ramp surfaces (29 and 36).  In addition, the first ring means is operatively secured to the housing (14) in which the bearing set is supported in such a manner as to preclude rotation of the first ring means (25) with respect to the housing (14).  A tang (30) presented from the first ring means (25) may interact with a slot (31) in the housing (14) to secure the first ring means (25) against rotation.  The second ring means (35) is selectively rotatable with respect to the first ring means (25) to effect axial translation of the first ring means (25) by virtue of the interaction between said opposed, contiguously juxtaposed ramp surfaces (53 and 54).  A latch plate (40) is disposed in proximity to the second ring means (35), and a tang (41) is also operative between the latch plate (40) and the housing (14) to preclude rotation of the latch plate (40).  A vernier locking means (45) is incrementally interactive between the latch plate (40) and the second ring means (35) selectively to secure the second ring means (35) against rotation and thereby secure the first lock ring (25) against axial translation.

Title: Controller for vending machine
Inventor: FURUYA YONEZO
IPC: G07F9/08
Filed: 1991-04-03
Abstract: A controller for a vending machine capable of selecting a mode in which the machine is made Possible to sell commodities even if change lacks. If a forced accep-tance switch sets a forced acceptance mode, Put-in coins are accepted even if no change can be paid. When the sum of the put-in coins arrives at a predetermined set selling price, the controller generates a selling enable signal. If the machine sells a commodity in response to the selling enable signal, it pays out change in the range of the sum in which change can be paid or within the sum of the coins remaining in change coin tubes. In this case, if the coins remaining in the change coin tubes do not satisfy the required sum of change, the overall sum of change is not paid out, but a user of the machine can get a desired commodity.
