Patent CA-2081557-A1 (CA)
Title: Production methods for metal matrix composites
Inventor: BECKER KURT J
IPC: C04B41/52
Filed: 1991-05-09
Abstract: The present invention relates to a novel process for forming metal matrix composite bodies. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Such spontaneous infiltration occurs without the requirement for the application of any pressure or vacuum. The molten matrix metal is provided in a unique manner which enhances the spontaneous infiltration process.

Title: Arrangement for clock recovery
Inventor: FRANK GEORG
IPC: H03L7/00
Filed: 1992-11-20
Abstract: PHD 91.167                                       09.11.1992 ABSTRACT: Arrangement for clock recovery.   The invention relates to an arrangement for clock recovery of a clock signal (t) from a data signal (d), comprising a data decision circuit (11) timed with the clock signal (t) to produce a decided data signal (c) on the basis of the data signal (d) and including a voltage-controlled oscillator (12) with a loop filter (13) preceding in the arrangement to produce the clock signal (t) on the basis of a control signal (k) that can be derived from the data signal (d) and the decided data signal (e). The arrangement is to be easily integrable. There is proposed that for producing the control signal (k) a DLL (Delay-Locked-Loop) correlation means (14) is provided. The arrangement may then be structured as a DLL delay correlator or as a DLL filter correlator.            Drawing Figure 1.
Patent CA-2083841-A1 (CA)
Title: Joints
Inventor: LINZELL GEOFFREY ROBERT
IPC: B23K35/22
Filed: 1991-06-13
Abstract: The invention relates to a method of making what may for convenience be regarded as friction joints - that is to say, joints be-tween the touching surfaces of two parts that are held in contact (by a force as experienced in a light interference, not one sufficient to cause forging) and that would otherwise move laterally past one an-other parallel to the touching plane, the method involving some mini-mal initial lateral movement of the two surfaces sufficient to cause some asperity deformation, leading to welding and shearing under special conditions - the phenomenon of "galling" - but not sufficient to raise the bulk temperature of either to a level where bulk welding will occur. More specifically, the invention provides a method of sec-uring against lateral motion two bodies (12, 14) held in face-to-face (11, 12) asperity contact, thereby to make a join between the two bod-ies, in which method there is inserted into the interface between the two bodies a material (15) that on minimal initial lateral relative mo-tion of the two surfaces promotes rapid but controllable "galling" (16) between the two surfaces, this galling binding the surfaces against further such motion.

Title: Apparatus for recording and reproducing video signals with subsampled chrominance signals
Inventor: HONDA TAKASHI
IPC: H04N9/79
Filed: 1992-12-08
Abstract: PATENT                ABSTRACT OF THE DISCLOSURE          In an apparatus for processing an input video signal that includes a chrominance signal and a luminance signal, the luminance signal is frequency-modulated and the chrominance signal is subsampled, preferably by field-offset subsampling, whereupon, the subsampled chrominance signal is frequency-converted to a lower frequency band than the frequency band of the frequency-modulated luminance signal.  The frequency-modulated luminance signal and the frequency-converted subsampled chrominance signal are then combined and the resulting combined signal is recorded on a recording medium such as a magnetic tape.          During reproduction of the recorded signal, interpolation among frames is used to reconstruct the chrominance signal.  Recording of the frequency-converted subsampled chrominance signal allows for space-efficient recording of the video signal while providing a reproduced chrominance signal that has a relatively wide bandwidth, thereby permitting improved color reproducibility.

Title: Ablating gelatin pig and method for use in tubulars
Inventor: LOWTHER FRANK E
IPC: E21B41/02
Filed: 1992-04-09
Abstract: An ablating pig (20) comprised of a mass of gelatin for use in treating tubulars (15). The pig will ablate as it passes through the tubular thereby depositing a treatment layer (21) onto the wall of the tubular. The pig can be molded outside the tubular or it can be formed in situ. The pig is formed by mixing common (i.e. technical) gelatin of the type derived from collagen with a heated liquid and a treating solution (e.g. corrosion inhibitor, drag reducer, etc.). In one aspect, magnetic particles (13) are entrained in the mass. The mass can be integral or it can be made up of individual components of gelatin. A slug of the treating solution can also be passed through the pipeline between two ablating gelatin pigs. For high temperatures applications, a hardener may be used to increase the melting temperature of the gelatin.

Abstract: MONITORING APPARATUS FOR ESTABLISHING PATIENT       PRESENCE IN A SUPPORTING STRUCTURE    Abstract Of The Disclosure A capacitive sensor pad includes a foam plastic pad and heavy aluminum foil plates located to the opposite side thereof.  The plates are adhesively bonded to the inner surfaces of an outer cover.  The capacitor of the pad is connected in circuit with an oscillator and produces a frequency related output.  A ripple counter establishes a frequency related output related to the capacitance.  A microprocessor reads the counter output and a plurality of samples are averaged to establish a reference base and the true weight effect of the patient on the sensing pad.  Other factors which might effect the signal are readily attended to by programmed compensation.  Each subsequent sample is averaged and compared with the reference base.  If within a permitted range, the latest and current signal is averaged with the reference base and establishes a new base, and continuously tracks changes in the sensing system.  A selected change in a selected time delay system by requiring a series of alarm states or immediately if advance warning is desired, actuates an alert or alarm system, which requires positive resetting to terminate the alarm system.  The system is positively reset to return to normal position monitoring.  The system may be set to automatically reset the alarm system after an alarm condition is established and then removed by the continuous tracking of the patient movement.
