Patent CA-1281108-C (CA)
Title: Method for zero byte time slot interchange
Inventor: GORSHE STEVE
IPC: H04L7/00
Filed: 1987-11-19
Granted: 1991-03-05
Abstract: A METHOD FOR ZERO BYTE TIME SLOT INTERCHANGE          ABSTRACT OF THE INVENTION This method is a scheme for suppressing excessive amounts of logic zeros transmitted via T-carrier line facilities between switching systems or channel banks.  This scheme provides proper zero bit suppression for alternating mark inversion signalling (AMI).  A proper AMI signal contains no more then 15 consecutive logic zero bit positions.  This scheme provides for encoding and decoding a 4 frame octet group of an extended superframe.  Logic ones are introduced into octets which would otherwise violate the AMI signalling rules.  These logic ones are then removed by the receiving system and replaced with the indicated all zero octets before being given to down stream processing.  This scheme provides for minimal buffering at the encoding system, which facilitates error detection and correction by the decoding system.

Title: Particulate trap exhaust muffler
Inventor: ILES LAWRENCE F
IPC: F01N3/021
Filed: 1988-02-09
Granted: 1993-04-27
Abstract: Abstract of the Disclosure A particulate trap exhaust muffler for use with a diesel engine and comprising a casing having an internal wall dividing the casing into an inlet chamber and an outlet chamber.  The wall is formed with a plur-ality of openings and a plurality of generally parallel tubes are disposed within the outlet chamber with one end of each tube being mounted within one of the open-ings in the divider wall, while the other end of each tube is closed.  At least a portion of the length of each tube is formed with perforations or holes.  A cylindrical particulate trap is spaced concentrically outward of each tube to provide an annular chamber therebetween.  Exhaust gas entering the inlet chamber flows into the tubes and through the perforations into the respective annular chambers to decrease the sound energy, and then passes outwardly through the cylin-drical traps where particulate material is trapped and burned off.  The exhaust gas then is discharged from the outlet chamber through an outlet.

Title: Tobacco reconstitution
Inventor: LUKE JOHN A
IPC: A24B15/14
Filed: 1988-02-22
Granted: 1992-01-14
Abstract: "Improvements Relating to Tobacco Reconstitution"   A B S T R A C T    Tobacco is reconstituted to provide a product of tobacco-filler size particles.  Particulate tobacco, starch, binder and water are fed to an extruder, the operating conditions being such that in the sheet form extrudate water flashes off to steam, thus to expand the extrudate.  While in the plastic phase, the extrudate is subjected to a draw down step.  The extrudate is then cut to particle size.
Patent CA-1337277-C (CA)

Abstract: HIV-directed inhibitors of the natural 2'-5'A antiviral defense pathway, diagnostic procedures and materials, and modalities for treating viral disorders are described.  HIV-induced inhibitors of RNase L in patients with lymphadenopathy (LAS), AIDS-related complex (ARC) and acquired immune deficiency syndrome (AIDS) were isolated and identified.  Functional 2-5A is not able to activate RNase L in the peripheral blood mononuclear cells (PBMC) in these patients; endogenous dsRNA, especially mismatched dsRNA, activates 2-5A synthetase which results in an increased concentration by endogenous 2-5A.

Abstract: A B S T R A C T    The apparatus comprises a laser means          for the frequency n1      and the frequency n2     , in each case one polarizing beam splitter          for producing cross-polarized partial beams of frequency n1          or n2        , in each case one modulator for displacing the frequency of in each case one of the partial beams by frequency f1 or f2, in each case a pair of deflecting mirrors                  and in each case a polarizing beam splitter for combining        the partial beam n1, n1+f1, n2, n2+f2;  two photodetectors         , upstream of each of which is arranged a polarizer         , a Michelson interferometer, a non-polarizing beam splitter      for splitting the partial beams into in each case a measuring light beam      or a reference light beam     .  The reference light beam passes to the associated photodetector     .  The measuring light beam      passes into the Michelson interferometer and then to the associated photodetector .  The signals of the photodetectors are demodulated according to the amplitude and the phase difference between the two demodulated signals is determined.  This phase difference is only dependent on the position of the measurement object and the equivalent wavelength of the difference n1-n2. For stabilization or correction purposes, the apparatus can be duplicated and one of the constructions can be used as a reference.     The corresponding method is given and is used for determining positions or distances as a spacing between two positions. Uncertainties can be removed by covering the distance or changing the frequency accompanied by simultaneous integration of the phase difference over time.

Title: Relay circuit having a pulse generator for closing contacts
Inventor: TAMURA YOSHIHARU
IPC: H01H47/00
Filed: 1988-07-07
Granted: 1991-07-02
Abstract: "Relay Circuit Having a Pulse Generator for Closing Contacts"                     ABSTRACT OF THE DISCLOSURE In a relay circuit, a stationary contact of a relay is coupled to a DC voltage source and a moving contact of the relay is coupled to a load circuit. The moving contact is switched to the stationary contact in response to a rapidly rising edge of a DC voltage applied to the relay. A voltage sensor is connected to the moving contact for detecting a voltage which appears thereat. For operating the relay, a switch is closed to apply a voltage from the DC voltage source to a pulse generator. The pulse generator generates a rectangular pulse and applies it to the relay to cause it to switch the moving contact to the stationary contact. If a voltage is not detected by the voltage sensor at the moving contact after energization of the relay, the pulse generator reapplies a rectangular pulse to the relay until a voltage appears at the moving contact, whereupon the pulse generator applies a constant voltage to the relay.

Title: System for body impedance data acquisition
Inventor: WOOTEN RICHARD G
IPC: A61B5/05
Filed: 1989-05-23
Granted: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE    The unique system of the present invention provides an accurate valid measurement of human body composition consisting of fat tissue, lean tissue and body water.  The inventive methodology provides a procedure for quantitative measurement of the conductive potential of the body, which is based on the lean tissue content of the body, in a convenient and reliable manner.          In more detail, the quantitative measurement in accordance with the present invention is referred to as a "bio-impedance signal."  This electrical signal, in ohms, is derived from a means for measuring body impedance component of the system.  The resultant signal (three digit number, between 1 and 1000 ohms) is then entered into a modifying means component to accurately predict the body composition of the tested individual.  The unique modifying means, in one embodied form, comprises prediction formulas derived from biological data inputs including: a patient's height, weight, age and sex, to determine a "population prediction variable."  Thus, the unique modifying means of the inventive system interprets bio-impedance readings as "population specific", i.e., specific impedance values are exhibited by various pre-defined populations of individuals.          This specificity is related to morph-type, leanness, body water and age.  In accordance with the present invention, an algorithm formula approach to prediction formulas is utilized to define an appropriate individual or set of variables.

Granted: 1993-07-20
Abstract: RADIO FREQUENCY EXCITED RING LASER GYROSCOPE       Abstract A radio frequency excitation system is disclosed for use in conjunction with a ring laser gyroscope.  The radio frequency excitation system is comprised of a closed resonant cavity which surrounds a helical coil driven at a high radio frequency at a range of 5 to 550 megahertz.  This closed resonant coil surrounds one leg of a ring laser gyroscope which is carved out and exposed so that it may be surrounded by the resonant cavity.  Using such a radio frequency excitation system eliminates the need for high power DC discharge components such as cathodes and anodes, as well as problems inherent with properly sealing the cathodes and anodes to the monolithic frame of the ring laser gyroscope.
