Title: Tamper Evident Container Closure
Inventor: BECK MATTHEW R
IPC: B65D47/24
Filed: 1995-07-10
Abstract: A tamper evident closure construction is provided for use with a container of the type having a neck with a discharge orifice  therein.  The  tamper  evident  closure  construction includes a dispenser cap and a unitary,  one-piece,  tamper evident closure cover.   The dispenser cap includes a base connected to the neck and a dispensing portion connected to the base.  The tamper evident closure cover consists of an overcap and a container closure cap separated by frangible webs which, when permanently disengaged, allow access to the dispensing portion and provide a visual indication of tampering.   The container closure cap is fastened directly to the neck of the container   and   includes   a   breakaway   tamperband,   or alternatively, a snap-fit abutment arrangement, which provides an indication of attempts to remove the container closure cap from the neck.   The skirt of the container closure cap is directly coupled to the neck of the container, and includes an annular bead on an inside surface and an annular flange which cooperate to secure and seal the base of the dispenser cap against the neck around the discharge orifice.

The detector may include a passive microphone, connected to an audio output jack which is installed inside the casing, to listen to leaks in the underground water supply.
Patent CA-2154838-A1 (CA)
Inventor: MUELLER BERTHOLD
IPC: B31B50/00
Filed: 1995-07-27
Abstract: A  machine   for  producing  containers   comprises processing stations with components adaptable to the shape and size of the material sections used for the container.          In the case of a change in form, in particular a change in the format of the sections of material to be used, it is necessary to change the relevant adaptable components.          Instead  of  the  conventional  approach  where  the  new components must be fine-tuned after an exchange has taken place,  fitting surfaces are provided at the processing stations,  against  which  a  section  of  the  adaptable components can always be placed in the same position.          Therefore,  time-consuming  installation  of  exchangeable machine components is avoided.

Title: Control for cpap apparatus
Inventor: FROEHLICH JAMES P
IPC: A61M16/00
Filed: 1995-11-27
Abstract: The invention relates to continuous positive airway pressure (CPAP) respiratory therapy apparatus (10) for treatment of apnea, hypopnea and other sleep disorders, and particularly to a control for the CPAP apparatus. A blower (12) is connected through a hose (14) and a mask (11), such as a nasal mask or a nasal cannula, to the patient's respiratory airway. An air flow sensor (15) and an air pressure sensor (16) are located at the blower end of thehose (14). Optionally, a vent valve (13) also may be located at the blower end of the hose. The outputs of the sensors (15, 16) are used to estimate the air pressure at the mask and the output of the air flow sensor (15) is used to determine the gross air flow to the hose (14), the patient air flow and the occurrence of patient snoring. The output of the air flow sensor (15) also is used to generate a square wave breathing signal. The breathing signal may be used by a microprocessor (17) to control the optional vent valve (13) to establish different levels in the applied pressure during inspiration and expiration. The applied CPAP pressure may be increased in response to the detection of apnea and hypopnea events. The microprocessor detects and ignores mask leaks, open mouth breathing and exhale puff breathing.
Patent CA-2165257-A1 (CA)
Inventor: RENDALL JOHN S
IPC: C25C3/06
Filed: 1995-12-14
Abstract: In aluminum smelting by electrolysis, a double salt of KAlSO4, as a feedstock, is heated with a eutectic electrolyte, such as K2SO4, at 800°C for twenty minutes to produce an out-gas of SO3 and a liquid electrolyte of K2SO4 with fine-particles of A12O3 in suspension having a mean size of six to eight microns.  This is pumped into a cell with an electrolyte comprised of K2SO4 with fine-particles of Al2O3 in suspension, an anode and a porous cathode of open-cell ceramic foam material.  The cell is maintained at 750°C and four volts of electricity applied between the anode and the cathode causes oxygen to bubble at the anode and liquid aluminum to form in the porous cathode.  A channel within the porous cathode, and the porous cathode itself, are deep enough within the cell electrolyte that the pressure head of electrolyte is enough to overcome the difference in density between the molten aluminum and the electrolyte to pump molten aluminum from the channel out of the side of the cell.  The electrolyte K2SO4 is periodically bled-off to control a build-up of the material as aluminum is produced from the double salt of KAlSO4.

Title: Apparatus and methods for machine learning hypotheses
Inventor: FREUND YOAV
IPC: G06F15/18
Filed: 1996-01-22
Abstract: Apparatus and methods for machine learning the hypotheses used in the classifiercomponent of pattern classification devices such as OCRs, other image analysis systems, and and text retrieval systems. The apparatus and methods employ machine learning techniques for generating weak hypotheses from a set of examples of thepatterns to be recognized and then evaluate the resulting hypothesis against example patterns. The results of the evaluation  are used to increase the probability that the examples used to generate the next weak hypothesis are ones which the previous weak hypothesis did not correctly classify. The results of the evaluation are also used to give a weight to each weak hypothesis. A strong hypothesis is then made by combining the weak hypotheses  according to their weights.

Abstract: With this invention, the video signals are encrypted so that only the privileged viewers can watch the video signals.     A layer coding unit 5 divides video signals 3 into two layers and encodes each layer. An encrypting unit 65 encrypts the low-quality layer data items 57 according to the setting signal 63 from a secret level setting unit 61 and supplies the encrypted signal to a combining unit 77. An encrypting unit 73 encrypts the high-quality layer data items 59 according to the setting signal 71 from a secret level setting unit 69 and supplies the encrypted signal to the combining unit 77. At this time, the encrypting unit 73 effects encryption at a secret level higher than that of the encrypting unit 65.

Abstract: The present invention relates to shark cartilage extracts and to a method of producing the same, these extracts having anti-angoigenic properties (reduction of the area of blood vessels observed in vivo on experimentally induced tumors), tumor regressive activity in vivo as well as demonstrating a direct inhibitory effect on tumor cell lines. This process does not involve any denaturing solvent or product and does not involve the use of any enzymes. It consists of obtaining a blend of whole cartilage in an aqueous solution of neutral pH, preferably pure water, this blend being centrifuged and the pellet and supernatant kept for further processing. The pellet is iyophilized and tested for anti-tumor and anti-angiogenic activities in vivo and in vivo, with or without supernatant. The supernatant has been shown to have anti-angiogenic and tumor regressive activities in vivo. the composition of the supernatant has then been investigated by different ways. Fractionation of thissupernatant led to the characterization of some of its active components,The fractions were tested for their direct in vitro activity on cancer cell lines. Therefore, it is assumed that the non-fractionated supernatant has such an in vitro activity. Lyophilization substantially destroys the activity of these liquid fractions while no such abolition is observed in the solid extract.
