Patent CA-1299727-C (CA)
Title: Acoustic detection apparatus
Inventor: CAULFIELD DAVID D
IPC: G01V1/00
Filed: 1989-03-06
Granted: 1992-04-28
Abstract: The present invention relates to an apparatus for use in detecting the substance of an object contained within an enclosure. The apparatus is comprised of an acoustic transmitter for transmitting a pulse of acoustic energy at a first side of the enclosure. A first acoustic receiver is provided for receiving acoustic energy reflected from the object to produce a reflected acoustic energy signal. A second acoustic receiver is provided for receiving acoustic energy which has been transmitted or refracted through the object to produce a transmitted acoustic energy signal. A signal processor is connected to the transmitter and to said first and second receivers. The signal processor processes the transmitted pulse of acoustic energy, the reflected acoustic energy signal and the transmitted acoustic energy signal to produce an object signature indicative of the object. A comparator is provided for comparing the object signature with the signature of known objects to determine the substance of the object. In accordance with the present invention, "enclosure" is defined as being a hollow box like structure having an object to be detected and identified with respect to its substance located therein, for example, a suitcase containing and object, or a quantity of material having an object to be detected and identified with respect to its substance buried therein, for example, an object buried in the earth relatively close to the surface.

Abstract: ABSTRACT          A gas discharge display apparatus in the form of an electroluminescent gas filled panel adapted for quickly and inexpensively making a durable and robust luminous sign using image patterns transferred to the panel by painting, silkscreening, stencilling, lithography, or the like.  The apparatus generally includes a pair of substantially parallel spaced apart rigid plates, or sheets, enclosing an electroluminescent gas, and having variously located and kinds of conductive surface coatings used as electrodes for energizing the enclosed electroluminescent gas.  A plasma glow discharge is interactively obtained in the chamber by placing a ground coupled conductive member, such as a human hand, proximal to the chamber opposite the conductive surface.

Title: Method of casing off a producing formation in a well
Inventor: ARTYNOV VADIM V
IPC: E21B/
Filed: 1989-07-18
Granted: 1993-07-20
Abstract: ABSTRACT    The method of casing off a producing formation in a well includes drilling into the producing formation and reaming the borehole in the producing formation zone.  Then the producing formation is shut off with a fluid-impervious envelope of profile pipes which are reamed in the process of their setting by building up a pressure drop across them. Then the flow casing string is run into the well and cemented, followed by re-exposing the producing formation.  The running-in of the flow casing string is terminated upon its having entered the upper part of the fluid-impervious envelope.

Title: Stereo enhancement and directivity servo

Granted: 1992-10-20
Abstract: STEREO ENHANCEMENT AND DIRECTIVITY SERVO               ABSTRACT OF THE DISCLOSURE In a stereo system having sum and difference signals that are processed for stereo image enhancement, apparent directivity of the stereo sound is increased by the use of servo systems  (40,44)  for the left and right processed difference signals (L - R)p,  (R - L)p.  Each of the left and right servos (40,44) responds to the respective left or right stereo input signal (Lin, Rin) and amplifies in-creases in the respective left or right processed dif-ference signals.  The amount of amplification is control-led by feeding back the amplified or directivity enhanced difference signal (L - R)pe, (R - L)pe, first comparing it with the processed difference signal  (L -R)p,  (R - L)p before directivity enhancement, and then combining it with the input signal (Lin, Rin) in a preselected ratio so as to control the amount of amplification of the processed difference  signal  that  is  provided  for directivity enhancement.

Abstract: A novel family of crystalline, microporous aluminophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures of aluminophosphate gels containing a molecular structure-forming template. The family comprises a number of distinct species, each with a unique crystal structure. Calcination removes volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with uniform pores, the dimensions of which vary, among the individual species, from about 3A to 10A in diameter. The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydrocarbon conversions.

Abstract: An elevator system stopping control generates the difference between the actual speed value and a set point speed value on the transition from an unregulated travel phase to the regulated arrival or braking phase and prevents that difference from becoming effective so that the travel comfort is not impaired and the stopping accuracy remains assured. For this purpose, a multiplication factor is formed from the actual speed value and an associated nominal speed value by means of a divider during the travel phase before the onset point of braking and stored during the arrival phase in a memory. Stored in a travel curve memory are travel-dependent set point speed values, which values are multiplied by the factor by means of a multiplier and conducted as set point signals to a motor speed regulating circuit during the arrival phase.

Abstract: A method of detecting the presence of an indicating device in a restricted investigation zone, comprising the detecting of an indicating device (31) of a highly permeable material by emitting and receiving a magnetic field, where two coils (1, 2) are caused to emit a high-frequency magnetic alternating field, and a first one of the coils (1) emits an alternating field with a frequency (f,) different from the fre- quence (f<sub>2</sub>) of the field emitted by the second one of the coils (2), and at least one difference and/or sum frequency n f<sub>1</sub> + m f. occurring by intermodulation by means of the indicating device (31), where n and m are positive or negative integers, is caused to be received by one or several coils (9). According to the invention, a third low-frequency magnetic alternating field is caused to be emitted in said zone with a frequency (f,) substantially lower than the frequencies (f<sub>1</sub>, f<sub>2</sub>), which low-frequency field is caused to have a field intensity sufficiently high, independently of the fields with the frequencies (f,) and (f<sub>2</sub>) to put the indicating device (31) into saturated condition in step with the frequency of the low-frequency field. A filed re-emitted from the indicating device (31) hereby is detected by means of a detector device as an intermodulation occurring periodically with the frequency of the low-frequency field between the frequencies (f,) and (f<sub>2</sub>).

Abstract: A dispenser package (10, 100) for flowable substances of the type where the flowable product is contained within a flexible pouch (22) adhered to a relatively stiff material (12) and may be opened along a fault line (24) or cut pattern scored in the relatively stiff material with one hand by folding the stiff ends towards one another into a "V" shape containing one or more dimples, pyramidal shapes (26) or other protrusions on the fault line (24) or fault area. The protrusions (26, 40, 52, 54, 56) not only increase and concentrate the stress forces, so that even very tough, high barrier materials may be used in constructing the package and will rupture at the protrusions by the aforesaid folding motion, but also control both the aperture shape and flow direction of the flowable substance as it is dispensed. The ability to make the package of tough materials enables the package to contain substances under pressure which subsequently will be dispensed. A sponge-like material (65, 70) also may be compressed within the package shaped so that a ' portion (66) will project from the package on opening for use as a swab for application of the contents.
