Patent CA-2015285-A1 (CA)
Title: High speed fuse
Inventor: EHLMANN ARLIE H
IPC: H01H85/0445
Filed: 1990-04-24
Abstract: The high speed fuse employs stamped end bell and terminals rather than forged or machined parts. A slot for the terminal is punched through the end bell. The terminal is inserted into the slot in the end bell and staked in position. This insures a strong tight fit without requiring welding or soldering. One end of each terminal has coined ridges to facilitate automatic welding of the fuse link to the terminals. Round balls are used to seal the fill holes for the arc quenching material. Metal pins secure the end bells within the fuse housing but are not electrically connected to the terminals because of the insulative end bells.

Each of the teeth has a base and a working edge and is separated from neighboring teeth by generally elliptical primary cutouts which are oriented normal to the tangent of the working perimeter. The teeth are preferrably monolithic and of a uniform size and shape, and are both angularly set  and laterally displaced relative to the plane of the blade body.
Patent CA-2017449-A1 (CA)
IPC: A42B1/06
Filed: 1990-05-24
Abstract: ABSTRACT OF THE DISCLOSURE        A cap which is adjustable in size from a "small" size to an "extra large" size without destroying the asthetics of the "Norwegian" or "Skilegion" design is provided by modifying the shape of the side panel.  The side panel is shaped such that when laid-out flat the upper edge of the posterior portion extends along a shallow concave arc of curvature and the lower edge extends along a low convex arc of curvature.  As a result of this configuration, the length of the upper and lower edges of the posterior portion is greater than length of the posterior portion of a conventional "small" size cap by an amount which is at least equal to the total size adjustment which the cap is required to accommodate.  An elastic member is fastened at its opposite ends to spaced points on the posterior portion of the side panel, adjacent the lower edge thereof. The attachment points are spaced a sufficient distance from one another and the elastic member is sufficiently elastic to draw the posterior portion inwardly along its lower edge to reduce the length of the posterior portion to provide a first cap size and it is sufficiently extensible to permit the posterior portion of the cap to be expanded to provide a second cap size which is substantially larger than the first cap size.

Title: Composition
Inventor: BACKHOUSE BRYAN S
IPC: A01N43/80
Filed: 1990-06-08
Abstract: ABSTRACT                           COMPOSITION         A particulate composition comprising an isothiazolinone or isothiazolothione or a salt or complex thereof and a water soluble metal salt.  The salt is typically a metal salt, for example the sodium salt of 1,2-benzisothiazolin-3-one and the water soluble metal salt is particularly an alkali metal salt such as disodium hydrogen phosphate.  A preferred composition can be obtained by stirring together an isothiazolinone or isothiazolothione, a base and an alkali metal phosphate in the presence of water until a dry particulate product is obtained.  The particulate product is typically highly and rapidly soluble in water and may be stored in a container formed from a water soluble material, for example a bag formed from polyvinyl alcohol.

Title: Method and apparatus for topping off containers with liquid to predetermined headspace level
IPC: B65B3/08
Filed: 1990-01-12
Abstract: 2025238 9008065 PCTABS00001 Accurately reproducible filling to a selected headspace level of a rapidly moving line of containers (13) is obtained by using a single feeder screw (31) through at least a final portion of a filling region and an outfeed zone following the filling region. The containers are tilted to a predetermined angle, depending on the selected headspace level, during their progress through the filling region and then return smoothly to an upright condition in the outfeed transition zone, without splashing any of the liquid content. Apparatus for filling the containers includes a container support structure (54, 55) in the filling region that can be adjusted through a range of tilt angles in an arc centered on the longitudinal axis of the feeder screw. The apparatus also includes an elongated funnel (77) for delivering liquid to the containers and that can be pivoted forward to permit access to the filling region.

Title: Hermetically sealed damped sensor
Inventor: THUEN TORBJORN
IPC: G01P15/00
Filed: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE           A hermetically sealed sensor for initiating air bag inflation during automobile crashes includes a ball which undergoes a fluid pressure differential during a crash and thereupon moves to impinge upon and,  if the crash is of sufficient severity and duration,  to close a pair of contacts and thus cause air bag inflation.      The  hermetic   sealing   leaves   the   operating characteristics of the sensor unchanged despite changes in ambient atmospheric pressure.  The air pressure within the sensor can be established so as to give a desirable operating characteristic.          Also other gases such as helium can be used exclusively or mixed with air to achieve a desirable operating characteristic.

Title: Total containment welding of plastic tubes
Inventor: SHAPOSKA JOHN B
IPC: B29C65/20
Filed: 1991-02-21
Abstract: Plastic tubes are welded by placing a pair of tubes in a pair of aligned holders with each tube folded toward itself. A wafer is movably mounted in the gap between the tubes and is heated to cause the ends of the tubes to melt without actually cutting through the tubes. The melted ends of opposed tubes can be pressed into contact with each other to form a welded connection. In a variation a pair of cutting blades cut the folded ends of the tubes and the cut ends are then melted by a wafer and subsequently pressed into contact with each other.

Abstract: PATENT     Abstract of the Disclosure An improved  intravenous catheter  is disclosed which,  when properly positioned within a vein, provides a closed system cath-eter.  The closed system intravenous catheter comprises a cath-eter having a tapered portion,  a hub portion and a fluid-flow passageway extending therethrough.   A fluid-impermeable elasto-meric gasket member is disposed within the hub portion of the catheter for sealing the hub portion and the fluid-flow passage-way of  the catheter.   A skin-penetrating stylet of a stylet assembly extends through the elastomeric gasket member and the fluid-flow passageway of the catheter so that a puncture tip on a proximal  end of the skin-penetrating stylet extends outwardly from the  tapered portion of  the catheter.   As air-permeable, liquid-impermeable vent assembly is connected to an observation chamber of the stylet assembly so that blood flow into a flash-point cavity defined by the observation chamber can be observed and controlled.  The vent also permits auxiliary equipment to be connected without leakage of blood.  A retractable sheath for the skin-penetrating stylet is also provided which covers the skin-penetrating stylet when same is removed from the catheter so as to minimize exposure of health care workers to the potentially contaminated puncture tip of the skin-penetrating stylet.

IPC: F04B43/04
Filed: 1990-11-07
Abstract: The micropump comprises a silicon wafer (22), glass wafers (2, 24) and a control element (26). The wafer (22) is machined to define an inlet valve (36), a pump chamber (34) and an outlet valve (48). The inlet valve (36) comprises a membrane (40) defining an upstream compartment (38) and a downstream compartment (62), an orifice (42) and a sealing ring (46) surrounding this orifice.
