Patent CA-2026987-A1 (CA)
Title: Cue signal recording and detection system
IPC: G11B15/087
Filed: 1990-02-06
Abstract: The present invention relates to a magnetic recording/reproduction device (such as VTRs and DATs).  A cue signal becomes a mark of its position for automatic operation and automatic editing, to be recorded in advance with the contents of the program.  The frequency of the cue signal is selected as to the audio signal band.  On an auxiliary audio track (24) in a  magnetic tape (21), an audio signal as well as a cue signal is recorded in time division manner.  Determination is made of a correct cue signal by providing a mute period before the cue signal recording region and detecting a cue signal by a filter after the detection of a mute period.  The frequency ratio of the cue signal to control signal (CTL) is sought by a counter (6) for a CPU (7) to identify a cue signal in response to the frequency ratio.  By dividing the reproduced signal into blocks, the cue signal is detected from the cycle number distribution of the frequency. The efficiency of the cue signal recording/reproduction can be improved and the structure of detection simplified to carry out precise detection.

Abstract: APPARATUS AND RELATED METHOD FOR THE REMOVAL OF LABELS      AND FOIL TAGS ADHERING TO CONTAINERS, IN PARTICULAR, TO BOTTLES     ABSTRACT OF THE DISCLOSURE     An apparatus for the removal of labels and foil tags adhering at different levels to containers, in particular, bottles.  The bottles are gripped axially between a rotary plate and a gripping head on the circumference of a turntable, each of these is a gripping space.  Corresponding to each gripping space, there are high-pressure nozzles located on an inner circumference of the turntable relative to the bottles.  Jets of fluid from the nozzles are directed approximately tangentially to the surface of each bottle, so that the jets remove the label and the foil tag in a stripping process, and transport the labels and foil tags radially outward to a collector, which collector is equipped with a separ-ator to separate the labels and foil tags from one another.  The removal of labels applied with adhesive is facilitated if there is an anti-adhesive layer on the label between the adhesive layer and the label.

Title: Ultrasonic Measurement Apparatus and Method
Inventor: ORBAN JACQUES
IPC: G01N29/28
Filed: 1991-05-15
Abstract: Pulse echo apparatus and methods are disclosed for measuring characteristics of a borehole while it is being drilled.  A component of a bottomhole assembly, preferably a drilling collar , is provided with one or more ultra-sonic transceivers.  A pulse echo sensor of the transceiver is preferably placed in a stabilizer fin of the collar, but may also be placed in the wall of the collar, preferably close to a stabilizing fin.  Electronic processing and control circuitry for the pulse-echo sensor is provided in an electronic module placed within such collar.  Such pulse echo apparatus, which preferably includes two diametrically opposed transceivers, generates signals from which standoff from a borehole wall may be determined.  A method and apparatus are provided for measuring standoff and borehole diameter in the presence of drilling cuttings entrained in the drilling fluid. In a preferred embodiment, such signals are assessed by the electronic processing and control circuitry to determine if gas has entered borehole.  Three methods and apparatus are provided for such gas entry determination.  The first relies on measurement of sonic impedance of the drilling fluid by assessing the amplitude of an echo from an interface between the drilling fluid and a delay-line placed outwardly of a ceramic sensor.  The second relies on measurement of drilling fluid attenuation of a borehole wall echo.  The third relies on measurement of the phase of oscillations of echoes to identify large gas bubble entries. The pulse-echo sensor includes a sensor stack including a backing element, a piezo-electric ceramic disk, and a delay-line.

Abstract: In a radio paging receiver, a CPU selects (SA3) from call signals a specific call signal specific to the receiver and from message signals a specific message signal that follows the specific call signal and represents a specific message, which is displayed (SA23) on a display.  The CPU judges (SA20) whether or not the specific message is identical with a predetermined message.  An EEPROM memorizes (SA21) an inhibit signal when the specific message is identical with the predetermined message.  The CPU puts (SA23-SA25) the receiver out of operation when the EEPROM memorizes the inhibit signal.  The CPU makes (SA23) the display display the predetermined message when the EEPROM memorizes the inhibit signal.

Abstract: A B S T R A C T       A hydrometallurgical method comprising a leaching operation is provided for recovering copper from particulate copper sulfide flotation concentrate containing at least about 20% copper by weight, a significant portion of the copper in the copper sulfide concentrate being in the cuprous state.  The copper sulfide flotation concentrate in the finely divided state is subjected to leaching with an alkaline solution of ammonia plus ammonium sulfate of concentration ranging from about 30 gpl to 150 gpl of ammonia and about 25 gpl to 200 gpl of ammonium sulfate at a temperature ranging from about 10° C to 95° C, preferably about 20° C to 40° C, the amount of sulfide concentrate in the leaching solution ranging from about 25 gpl to 500 gpl proportioned at least stoichiometrically to the ammonia concentration of the leaching solution.  The sulfide concentrate is leached under substantially ambient pressure while continuously aerating the solution for a time at least sufficient to dissolve the cuprous copper and oxidize it to the cupric state while avoid or substantially minimizing the oxidation of sulfide sulfur to sulfate, and thereby obtain a filtrate containing at least about 15% of the total amount of copper in the concentrate and provide a washed residue containing at least about 20% copper by weight comprised substantially of cupric sulfide.  The copper in the leaching solution after further processing is subsequently recovered by electrowinning.  The residue can be further treated in a smelter to recover copper therefrom or upgraded by subjecting the residue to conventional flotation and provide a secondary flotation concentrate containing at least about 30% by weight of copper.
