Patent CA-2075344-A1 (CA)
Inventor: KO JUNG-WAN
IPC: H04N5/935
Filed: 1992-08-05
Abstract: A video recording/playback system includes in its recording electronics time-base correctors both for luma signal and for color-under signal, the time-base corrector for luma signal being used to facilitate comb filtering and the time-base corrector for chroma signal being used to maintain luma/chroma tracking during recording. The video recording/playback system includes in its playback electronics time-base correctors both for played-back luma signal and for played-back color-under signal, the time-base corrector for played-back luma signal being used to facilitate comb filtering and the time-base corrector for played-back chroma signal being used to maintain luma/chroma tracking during playback. With appropriate switching, the same pair of time-base correctors can be used in both the recording and the playback electronics of a video recording/playback system. A detector in the recording electronics determines when there is substantial time-base error in the video signal received for recording and conditions the comb filtering of the luma signal during recording to be carried out in just the spatial domain and not in the frame-to-frame time domain. The recording electronics includes circuitry for signaling the playback electronics, via a recorded signal, that the comb filtering of the luma signal during recording was carried out in just the spatial domain and not in the frame-to-frame time domain. The playback electronics responds to such signaling to adapt the comb filtering of the played-back luma signal to suit.

Filed: 1992-11-26
Abstract: Method and apparatus for applying a layer of insulation around an electrical cable core in which the contaminant size is not greater than about 200 microns.  Unplasticized insulation material, such as polyethylene, is supplied to an extruder which forces the material through a filter which prevents the passage of contaminants having a size greater than about 200 microns and in which there is a pressure drop.  The filtered material is delivered to a pump which increases the pressure thereon and forces it through a static mixer at the output of which the filtered material is delivered to the cross-head of extrusion apparatus which applies the filtered material to the cable core as it is advanced longitudinally.  If the insulating material is to be cross-linked by a cross-linking agent, the agent is injected into the filtered material between the pump and the mixer.

Title: Integrated centrifugal pump and motor
Inventor: COOPER PAUL
IPC: F04D29/18
Filed: 1991-09-27
Abstract: An integrated centrifugal pump and motor is provided by an impeller disk which contains permanent magnets and functions as the rotor for a brushless DC motor. The rotor is supported by non-contacting radial bear-ings and is hydrodynamically balanced against any axial thrust so that there is no contact between rotating and stationary elements during operation. Since the impeller disk is also the motor rotor, there is no need for a shaft, in he ordinary sense, which would penetrate the rose and, thus, require seals.   The resulting pump is compact and can be operated electronically at variable speeds.

Title: Pilot pressure sub-assembly for fluid control valve
Inventor: WASSON JEFFREY B
IPC: F16K3/24
Filed: 1993-10-04
Abstract: ABSTRACT OF THE DISCLOSURE A fluid control valve includes a spring biased pilot pressure sub-assembly for adjustably setting an initial step pressure.  The sub-assembly includes a spring seat and an axially movable spool.  The spool includes a body portion having a threaded outer surface.  A pair of lock nuts are threaded on the threaded body portion.  A pilot spring reacts between the lock nuts and the spring seat. The magnitude of the initial step pressure is dependent upon the magnitude of the force exerted by this pilot spring.  The magnitude of this force can be adjusted by changing the position of the lock nuts relative to the spring seat.  Because they are threaded onto the spool, rotation of the lock nuts causes axial movement relative thereto.  Thus, the position of the lock nuts on the spool can be adjusted simply by rotating them relative to the spool.  Such axial movement can be performed to increase or decrease (depending upon the direction of rotation) the effective length of the pilot spring and, therefore, the spring force generated thereby.  As a result, the magnitude of the initial step pressure increase can be adjusted quickly and easily.
