Abstract: AMPLITUDE AND FREQUENCY MODULATION SYSTEM Abstract of the Disclosure Combined amplitude and frequency-shift-keying (AM-FSK) modulation of a carrier wave by a baseband data signal achieves significant suppression of one of the sidebands to ease the design requirements of filters generally used in the transmission of FSK signals.  The significant suppression effect is observed when the ratio of minimum to maximum amplitude of the envelope of the amplitude modulated carrier wave is restrained to be approximately between 0.6 and 0.9.     In one embodiment amplitude modulation is performed by a pair of amplifiers, each having a pre-determined gain.  In another embodiment, an all digital technique is used to synthesize the AM-FSK signal.

Abstract: CANADA ABSTRACT          The invention comprises an electrical distribution system in which the electrical conductors (11, 12) are enclosed within a length of hollow conduit (10) which is formed with a continuous slot (20) in one wall through which a plug (14) can be inserted and rotated to bring its contact pins (77, 78) into contact with the conductors.  Gate means (32) located within the conduit have a normally closed position in which the conduc-tors are closed off from that part of the conduit containing the slot, and these are movable into the open position by entry of the plug through the slot.  By closing off the conductors from the remainder of the conduit, accidental contact with the con-ductors is prevented even though access to the interior of the conduit may be achieved via the slot.  In one embodiment of the invention, a keyway (50) is provided in the conduit and the plug is formed with a corresponding projection which engages the keyway when the plug is fitted into the slot.  The gate means is arranged such that it can only be opened by an element passing through the keyway, thus providing an additional safety feature.

Abstract: 197, 630 ABSTRACT OF THE INVENTION              Disclosed is an improved centrifuge apparatus for separating substances of varying density and a method of controlling the speed of a rotor of the centrifuge apparatus.  A desired centrifugal force and a desired accumulative centrifugal force can be entered by a human operator.  A control unit adjusts the rotor speed and operational cycle time to meet the inputted desired force values while displaying the actual accumulative centrifugal force at the end of the operation cycle.  A vent-view port is mounted for in-out adjustment within an access aperture formed in a lid of the centrifuge apparatus so as to provide for selective opening of vent holes formed in the vent-view port.  In addition to venting, the vent-view port has a sensor mount with a transparent window for receiving a tachometer probe for rotor speed monitoring.

The solvent is pumped from the sump for addition to the drum during the wash cycle and the pumped solvent is filtered to remove substantially all of the radioactive particu-late material suspended in the solvent.    The apparatus for decontaminating the radioactive garments comprises a sump for supporting a dry cleaning solvent.  A drum for supporting the radioactively con-taminated garments during a wash cycle which separates the radioactive particulate material from the garments means are provided for continuously pumping the dry cleaning solvent from the sump to the drum and for con-tinuously removing the solvent and separated particulate material from the drum into the sump.  A filtering means is used to continuously remove substantially all of the particulate material suspended in the solvent that is carried to the drum.
