Patent CA-2229950-A1 (CA)
Title: Liquid dispensing pump having water seal
Inventor: SIEGEL KENNETH D
IPC: B05B11/00
Filed: 1998-02-19
Abstract: A manually actuated pump dispenser has a water seal for maintaining the container vent ports sealed closed during pumping until at or near the end of the pressure stroke whereupon a vent path through which only air is permitted travel into the container, is open as the path is shielded against water entering the vent path when pumping in a wet environment as when dispensing hair shampoo or hair conditioner. In a plunger lock-down position of shipping and storage, leakage of product through the vent ports is substantially avoided during a superatmospheric condition within the container.

Patent CA-2235743-A1 (CA)
Title: Closure for a bottle or the like
Inventor: HERTRAMPE MICHAEL
IPC: B65D41/04
Filed: 1996-10-25
Abstract: The invention concerns a closure for a bottle or the like, the closure comprising: a cap-like closure part; a projection directed inwardly from the edge of the cap-like closure part for engaging behind an outwardly directed projection on the neck of a bottle or the like; a substantially cylindrical sealing part extending inside the closure part axially outwards from the base thereof; and a radial projection which is formed on the outside of the sealing part, at a spacing from the base of the closure part, and has a diameter which is larger than the internal diameter of the neck of a bottle to be closed with the closure, such that the sealing surface or sealing edge formed by the projection rests tightly on the inner surface of the neck when the bottle or the like is closed. Directly radially outside the cylindrical sealing part (4) the cross-section of the base (3) has a constricted portion (8), acting as a hinge. The radial projection (5) is disposed axially such that it lies in the region of the substantially cylindrical inner surface (6) of the bottle neck (2) whenever the base curves outwards as a result of excess pressure. If excess pressure occurs, the base (3) curves and thus rotates the sealing part inwardly about the constricted portion (8) of the base cross-section, such that the projection (5) is raised off the inner surface (6) of the bottle neck (2) and the excess pressure can escape. The sealing effect is permanent and the excess pressure is reliably relieved.
Patent CA-2237483-A1 (CA)
Title: Means of increasing capacity in cellular radio (mobile & fixed) systems
Inventor: WARD CHRISTOPHER ROBERT
IPC: H04W16/12
Filed: 1998-05-12
Abstract: The disclosure relates to a method of configuring a plurality of directional beams (31-34) in a cellular radio system having a plurality of antennas each communicating over a corresponding respective sector area by re-arrangement of directional beams using a same or like carrier frequency to each other, so as to be directed away from each other, and by restricting signal loading on beams experiencing worst case interference. Interference between geographically close sectors is reduced by the method resulting in an improvement in carrier to interference ratio performance. Carrier frequencies of inner two beams (32, 33) transmitted by an antenna are exchange for inner two beams which are transmitted in substantially the same direction by another antenna. Inner beams experiencing highest interference are restricted so as to operate at below theirmaximum signal load in order to reduce interference within the network. This results in an improved carrier to interference performance for all beams and mayallow increased use of a lower frequency reuse factor. The techniques disclosed are applicable to sectors in center-excited cell arrangements or tri-cellular systems.

Filed: 1998-11-05
Abstract: Jar lid opener that also can be used to grip only or to grip and then apply rotating force to the other cylinder surfaces as well such as pipes, bolts, nuts, jar necks.      Jar lid opener consists of a flexible yoke to embrace and then grip the lid, a case of an appropriate form having cuts to insert the yoke ends into the case. The case forms optimum (or close to optimum) position of the yoke relative to the lid when the lid is pressed toward the case's butt-end by the yoke. This position provides prevalence of forces tightening the yoke around the lid over the forces causing sliding of the yoke along the side surface of the lid when the rotating moment is applied to the case to open the jar lid. The guides inside the case form the outside yoke shape close to the lid one. There is a pulling screw one end of which is screwed to the nut inside the case and the other end is passed to outside the case through the hole or cut at the case's butt-end opposite to the one the lid is pressed toward to. Outside end of the screw does have a handle to rotate the screw. Both yoke ends are attached to the nut the pulling screw is screwed to, this nut does have such shape and size that it cannot be rotated inside the case, so when the screw is rotated, the nut is moving along the case in the case's cavity and pulls or pushes the yoke ends. Pulling screw does have a stop preventing the screw from leaving the case. Case does have a cover that is connected to the case by glue, screws or by other means for convenient assembling of the jar lid opener.

Patent CA-2254470-A1 (CA)
Title: Method and apparatus for reproducing lighting effects in computer animated objects
Inventor: MUNROE EARL ROBERT
IPC: G06T15/50
Filed: 1998-11-24
Abstract: A method and apparatus for reproducing real-world lighting effects in a computer animated object, in which a three dimensional virtual set is created in proportion to the physical set, optical parameters of each physical light source used on the real-world set are input into the model and qualified by effects such as dimming, filtration, diffusion, occlusion and attenuation to produce synthetic lighting of the virtual set.  The camera lens transmission characteristics and film speed may also be incorporated into the virtual set parameters. The three dimensional computer animated object is positioned and oriented within the virtual set according to the position and orientation in which the visual effect is to appear in the cinematographic scene, and is thus synthetically illuminated within the virtual set in exactly the manner that a physical object of the same shape in the physical set would be illuminated, to produce a computer animated object that exhibits lighting effects as would appear in a comparable physical object photographed through the same camera lens using the same film as used in the physical set. The invention thus eliminates most of the judgment required on the part of a visual effects artist trying to reproduce in a computer animated object the lighting effects used in a cinematographic scene, and thus significantly reduces the time required to integrate the visual effect object into the cinematographic scene. Inherent characteristics of many light sources, filters, cameras and films can be maintained in a database or look-up table and can thus be entered into the virtual set by reference to the actual light sources and camera used on the real-world set.

Title: Magnet device with double fixing positions for changing the magnetic circuit
Inventor: SHENG CHIH-SHENG
IPC: H01F7/16
Filed: 1999-05-04
Abstract: A magnet device with double fixing positions for changing the magnetic circuit is provided, and includes an external housing whose inner edge is fitted with a coil The inside of the external housing includes a space for the axial movement of an iron core. The external housing and a positioning cover at the opening end of the housing are made of metal with excellent magnetic conductivity. The iron core is connected to a permanent magnet which is fixed at the inner side of the positioning cover. A drive circuit is provided whereby a positive impulse voltage will be output and the electrical energy is saved in a capacitor when the power is switched on. A discharge current is created to output a negative impulse voltage after the power is switched off, and the positive and the negative impulse voltages serve to make the coil change the direction of the magnetic force by the excitation process, so that a push force or a pull force on the iron core will be created for movement thereof. The permanent magnet will be forced to change the magnetic circuit and the iron core under ordinary circumstances will be kept at the pre-arranged position without continuous waste of electricity. Not only can this save electric energy, but it will avoid creating an over-heated state or a short circuit, so that a dangerous situation is prevented and the useful life of the device is extended.
