Patent CA-2187379-A1 (CA)
Inventor: MCNAB GERALD FREDERICK
IPC: B65D47/06
Filed: 1996-10-08
Abstract: A pouring spout having an assembly of two tubes each having large and small diameter axially extending regions. The tubes are telescoped together with the large diameter regions slidable upon one another and the small diameter regions slidable upon one another.  This arrangement provides a particularly stiff structure which is resistant to bending. The stiffness is enhanced by a frusto-conical region of each tube disposed between its large and small diameter regions. The tube assembly is normally held in an axially expanded state by a spring which also closes a valve.  The tubes are axially-contractible by end pressure applied in use and this also opens the valve.  When axially collapsed, the frusto-conical regions mutually engage thereby further stiffening the structure in use and also providing a seal against back flow of fluid.  The structure is of particular use for transfer of gasoline  into storage containers for internal combustion engines and is robust and safe in use in that resistance to fluid spillage is maximized.  A valve closure member of the structure is maintained correctly aligned at all times with its valve seat.

Title: High-safety control device for electric heating appliances
Inventor: WEISS JOHN
IPC: G05D23/24
Filed: 1994-01-19
Abstract: A heater for a heating pad uses heating elements of positive temperature coefficient (PTC) material arranged in parallel between a conductor connected through a fuse (5) to an ungrounded pole of electric a.c. mains and a conductor connected through a triac switch (T1) to a grounded pole of the a.c. Both of these conductors have safety link extensions for providing to a micro-controller integrated circuit (14). When a fault occurs such as a break in a conductor in or near the heater, (PTC) a neon breakdown tube connected to the safety link extension of the ungrounded conductor quickly extinguishes for lack of voltage. Other faults are detected by the grounded conductor extension which has a voltage divider to ground. An a.c. signal from its tap controls a transistor (Q1) which is pulsed ON when the transistor (Q1) is not biased OFF because of a fault.

Title: Method and system for preservation against pesky birds and pest animals
Inventor: ESTINES JOSETTE
IPC: A01M29/16
Filed: 1997-03-27
Abstract: The  method  according  to  the  invention  is  permanent preservation against pesky birds and pest animals from a site where they cause damages. The method comprises: a dislodging phase where at least two frightening devices are installed on the site. The number of devices installed depends on the kind of site and the surface area of the site. For a short period of time during the dislodging phase, an intensive action of the frightening devices is sustained to dislodge the birds. The dislodging phase is followed by a dissuasion phase to dissuade the birds from returning back to the site. The dissuasion phase includes an active action of the frightening devices for three days.  The active action is less severe than the intensive action of the dislodging phase. Finally, there is a controlling phase including a continuous action of the frightening devices to permanently prevent any bird or animal from settling on the site.

Title: Valve-gated injection moulding device
Inventor: KUNTZ JOHN PETER
IPC: B22D17/22
Filed: 1997-10-07
Abstract: The invention relates to a valve-gated injection moulding device, wherein the actuating device of the valve pin comprises a first arm and a second arm. The first arm is hingingly connected in a first end to the rearward end of the valve pin. The second end of the first arm is hingingly connected to displacement means, which can be moved along a radial displacement trajectory. The second arm is with its first end hingingly connected to the midpoint of the first arm. The second end of the second arm is connected in a fixed hingepoint to a support of the injection moulding device. In this way, using a radial actuating device, only an axial force is exerted on the valve pin. The stroke of the valve pin can easily be adjusted from outside the mould by increasing or decreasing the stroke of the piston. The actuating device according to the present invention is relatively small, and does not require a large re-routing of the melt passage as it is positioned radially outwardly from the longitudinal centre line of the valve pin. It can be operated from outside  the mould.  The adjustment of the height of the valve pin can take place outside the mould.

Abstract: L'invention porte sur des composés peptidomimétiques comprenant un aminoalkylbenzène convenablement substitué et des analogues d'analine, à nouveau substitué par un deuxième noyau de phényle fixé par liaison, un lieur d'hétéroatome ou un lieur aliphatique. Les composés instantanés bloquent l'enzyme farnésyle-protéine transférase et la farnésylation de certaines protéines. En outre, les inhibiteurs instantanés farnésyle-protéine transférase se différencient des autres inhibiteurs de la farnésyle-protéine transférase décrits précédemment par le fait qu'ils ne possèdent pas de fraction moléculaire de thiol. L'absence de thiol apporte des avantages uniques en termes d'amélioration du comportement pharmacocinétique chez les animaux, de prévention de réactions chimiques liées au thiol, telles que l'autoxydation rapide et la formation de disulfure avec des thiols endogènes, et de toxicité réduite pour l'organisme. L'invention comprend également des compositions chimiothérapeutiques renfermant ces inhibiteurs de la farnésyle-protéine transférase et des procédés permettant de les fabriquer.

Title: Methods of minimizing scattering and improving tissue sampling in non-invasive testing and imaging
Inventor: SODICKSON LESTER
IPC: G01N33/487
Filed: 1996-04-02
Abstract: An improved method and apparatus for use in optical testing of concentration in samples has been developed. The apparatus restricts the solid angle of illumination and the solid angle of detection to eliminate a high proportion of the scattered radiation while allowing the ballistic radiation and the snake-like radiation to be transmitted. In samples which contain multiple scattering centers, this allows less correction for variations in effective pathlength and allows easier calibration of the apparatus. The use of polarized radiation as a means of minimizing scattered radiation in the sample is also disclosed. In a second embodiment the detector collects only polarized radiation while excluding depolarized (multiple scattered) radiation. The radiation preferrably is chosen to be in the 700-1500 nm wavelength range. The sample preferrably is a portion of a mammalian body, the analyte to be analyzed is selected from the group consisting of glucose, glucose identifying substances, mixtures thereof or from the group consisting of hemoglobin, deoxyhemoglobin and mixtures thereof. The concentration measurement can be used to derive oxygen saturation of the blood.

Abstract: Apparatus (300) is disclosed for locking a key (322) in a keyway (302) of a shaft (10) and of a hub slideably receiving the shaft (10). The key (322) is tapered and includes a top extending at an acute angle to the bottom, with the keyway (302) of the shaft (10) having a bottom wall (306) at the acute angle to the axis of the shaft (10). A push rod (312) is rotatable in an axial bore (308) in the shaft (10) and includes a threaded portion (318) threaded into a threaded counterbore (310) of the axial bore (308). The forward end of the push rod (312) is interconnected to the key (322) by a lip (336) formed in the key (322) extending into a notch (316) formed in the push rod (312). Rotation of the push rod (312) causes the push rod (312) to move axially in the axial bore (308) which in turn axially moves the key (322) in the keyway (302). Due to the angles of the key (322) and the keyway (302), the radial spacing of the top (330) of the key (322) from the axis of the shaft (10) varies depending upon the axial position of the key (322) in the keyway (302).
