Abstract: A solarium, a kit and a method for building the same. The solarium includes window panel frames for supporting a plurality of window panels. Each window panel frame has a set of frame members. Each frame member defines a frame member first peripheral surface, a diametrically opposed frame member second peripheral surface and a pair of frame member third peripheral surfaces extending therebetween. The frame member third peripheral surfaces define a third surface connecting recess positioned adjacent their corresponding intersection with the frame member first peripheral surfaces. A panel locking component is attached to the marginal edges of the window panels. The panel locking component defines a pair of locking tongues pivotally attached together by an hinge allowing relative pivotal action between an unlocking and a locking configuration. The window panels are made of a relatively thin and flexible sheet of material. They are configured and sized so as to be in a tense state when mounted to their corresponding window panel frames. The window panel are made of a material allowing selective size adjustment thereof such as heat shrinkable polymeric resins. The window panel are undersized relative to the window peripheral frame when not mounted thereto. During the mounting operation, they are first secured to the window panel frame using the panel locking component and then shrunk to a tensed state.

Title: Closing cap for motor vehicle radiator
Inventor: REUTTER HEINRICH
IPC: F01P3/22
Filed: 1998-12-03
Abstract: The invention relates to a closing cap (10) for the fixed tubing of a motor vehicle radiator, comprising an inner part (14) with a flow connection means between the inside and the outside of the container, as well as a distributing mechanism for freeing and closing the flow connection means. A valve body (22) of the distributing mechanism (11), which can be reciprocated, is compressed under pre-stress towards the inside of the container against a sealing seat (21) at the inner part (14) of the cap, so that said valve body can be lifted from said sealing seat (21) when a threshold value of the pressure inside the container is exceeded. In order to produce a closing cap (10) which does not open in case of overpressure resulting from heat accumulation and which ensures that the container is protected in case of a continuing increase of pressure, in a simple and cost-effective way, the invention provides for in-use controlled adjustment of the pre-stress used for compressing the valve body (22) against the sealing seat (21).

Patent CA-2315795-A1 (CA)
Title: Coding method and apparatus
Inventor: RICE MARK
IPC: H04L1/00
Filed: 1997-12-24
Abstract: A parallel concatenated coder (20) outputs a sequence of data sets in which earlier data sets contain data bits (d) and non-interleaved parity bits (p) without interleaved parity bits (q), while later data sets include the interleaved parity bits (q). Each data set is modulated as one symbol. The output format partially overcomes the delay incurred by interleaving the parity bits (q), with a substantially even distribution of data and parity bits in the sequence of data sets. The delay may be reduced further by interleaving with an index constraint.
Patent CA-2317684-A1 (CA)
Inventor: OOTORI YASUHIRO
IPC: A45C13/18
Filed: 1999-11-05
Abstract: In a strap assembly for carrying a portable device, in order to protect a user against the action of an unexpected sudden external force, a cord (20) for installing the strap assembly to the portable device is passed through an installation hole (34) of a coupling (30) from the inside such that a knot of a strap is supported by the rim of the installation hole. Coupling holes (11) in both ends of the strap (10) hung from the body of the user are fitted over support posts (37a, 37b) formed on the inner bases (38) of first and second coupling members (31, 32). Tapered surfaces (39a, 39b) are formed on portions of the cylindrical side surfaces of support posts (37). When the first and second coupling members are closed together with their rims superposed, protrusions (35) of one member engage recesses (36) of another coupling member. If a tension load in excess of a given level is applied to the portable device, a reactive force from the strap acts upon the tapered surfaces (39), resulting in force components that release the engaged state of these protrusions (35) and recesses (36). This causes the first and second coupling members (31, 32) to spread open, thus separating the strap (10) therefrom.

IPC: H04W16/18
Filed: 1999-01-19
Abstract: Utilizing a three pass processing procedure, a frequency plan revision proposal is defined, verified, implemented and confirmed by a network operator. In a first evaluation pass (100), interference and bit error rate measurements (106) are evaluated and used to create one or more proposals.  These proposals are evaluated (108) to confirm compatibility with the current cell configuration, coordination with previous proposals, and assignment of frequencies. In a second pre-update verification pass (102), more measurements (106, 114) are evaluated (116) to confirm (118) the first pass proposals. A  single proposal for each selected cell is then chosen for implementation in a network update (112). In a third post-update verification pass (104), the measurements (106, 114) are again evaluated (122) to verify (124), following the update, that the implementation of the proposal had a positive effect on the network.

Patent CA-2330600-A1 (CA)
Inventor: KARIDI RON J
IPC: B41J2/485
Filed: 1999-07-07
Abstract: A general purpose method for text enhancement that is independent of the type of scanner that is used to scan a document or the device printing the document and is tolerant of the artifacts and defects that the scanning process introduces on the text, mainly blurring. A window of size W x W is constructed on a scanned page with the target pixel at the center of the window and the amount of ink in the window is calculated and the number of pixels that are darker than the center pixel is counted. The window is moved along the page and each pixel on the page has a chance to be the center of a window and be allocated ink. The invention reallocates the amount of ink in full quantities of the darkest value. Only the center pixel actually has its ink reallocated. A key principle is to make an attempt to allocate the ink pixel by pixel in the window, where the darkest pixel gets ink, the second darkest gets ink, and so on, until there is no more ink remaining in the bank. If the center pixel is later in darkness and there is no ink left in the bank, then it is set to white. If the center pixel is reached before the ink runs out, then it is set to black.

Patent CA-2337700-A1 (CA)
Inventor: FREE MYRON
IPC: B65H39/14
Filed: 2001-02-21
Abstract: This invention provides a method and apparatus for applying tape tabs to a traveling web, for example, for placement of fastening tabs on a running web of disposable diapers. The invention provides a cutting roll positioned to cut segments from a continuous infeeding web of tape material against a rotating anvil. The anvil, which is traveling at a speed equal to or very close to that of the infeeding tape web, carries the tape segments to a point on its tangency where a higher-speed traveling diaper web most nearly approaches, at which point the traveling diaper web is displaced slightly toward the anvil by means of a protuberance acting against the web. This movement causes it to come into contact with the next available tape segment, which becomes adhered to the higher-speed traveling web. This process provides for operation at higher speeds, higher efficiencies, greater flexibility and lower noise levels than previous processes.
