Patent CA-2229928-A1 (CA)
Inventor: SUFFA UDO
IPC: B65D55/02
Filed: 1996-08-23
Abstract: The invention concerns a closure comprising a lid (2) and a body (1), wherein part (3) of the body (1) can be pressed in radially and secured in the pressedin position to form a recessed grip. The part (3) can be secured permanently and non-detachably and can thus act as a tamperproof device indicating that the closure is opened for the first time. In addition, an indicator plate (6), which is torn off when the part which can be pressed in is pressed in, can be provided as a further tamperproof device. Furthermore, when the lid has been raised, the part which can be pressed in can return to its initial position, such that when the lid is closed again, the closure can only be re-opened when the part which can be pressed in is pressed in again. This embodiment provides a tamperproof device in the form of an indicator plate (6) disposed on the part which can be pressed in. Furthermore, the return of the pressed-in part into its initial position provides a child-proof closure.

Inventor: SILVERMAN VLADIMIR
IPC: G06F3/048
Filed: 1998-02-27
Abstract: A secure and scalable system and method is described for carrying out database transactions over a network.  A transaction server on a network authenticates a user connected to the network with a client.  The database access permission of the user is determined  and the transaction server sends a graphical user interface that comports with the access permission of the user to the client.  The transaction server receives a user database request from the client based upon inputs provided by the user through the graphical user interface.  The transaction server selects an action statement with formal parameters based upon the user database request.  The action statement is evaluated by replacing its formal parameters with values from the user database request. The evaluated action statement is executed on a database, and the results are sent to the client  where they are displayed to the user through the graphical user interface.
Patent CA-2231061-A1 (CA)
Inventor: JONES WILLIAM THOMAS
IPC: B65D50/04
Filed: 1998-03-04
Abstract: A medication container has a tubular container body with an open upper end, and a cap detachably securable to the upper edge of the container body by clockwise rotation relative thereto, the cap and the container body having mutually engageable stops preventing anti-clockwise opening rotation of the cap relative to the container body when the cap is in an upper position relative to the container body. A cap liner of resilient material within the cap has a peripheral portion engageable with the upper end of the container body to close the upper end, the cap liner also having a central button portion in a central aperture in the cap for manual engagement by a person wishing to open the container. The cap is normally engaged by the cap liner, when the cap is detachably secured to the container body, to maintain the cap in the upper position relative to the container body, whereby downward manual pressure on the central button portion of the cap liner causes resilient deformation of the cap liner away from the cap to permit the cap to be depressed from its upper position and thereby permit counter-clockwise opening rotation of the cap relative to the container body.

Title: Building element and method for manufacturing a building element
Inventor: LOF ROGER
IPC: E04B1/10
Filed: 1995-11-03
Abstract: The invention relates to a method of manufacturing building elements in the form of logs, preferably timber logs, provided with jointing recesses which define a joint centre pin. According to the method, the logs are cut into modules optionally in different total lengths, and each module is then centred in relation to a selectable longitudinally extending centering line. The centering line is chosen so that it will form a longitudinal centre line for the joint centre pin in the finished building element. The module is then worked on two mutually opposing sides in its longitudinal direction, such as to provide abutment surfaces. These abutment surfaces coact with corresponding abutment surfaces of nearest adjacent modules. The invention also relates to a building element manufactured in accordance with the method, and to a building constructed by joining together these building elements.

Abstract: Improved processes have been developed for atom (or group) transfer radical polymerization (ATRP). In one improvement, the ATRP process involves polymerizing in the presence of a (partially) free radical-deactivating amount of the corresponding reduced or oxidized transition metal compound. In a further improvement, the ATRP process involves polymerizing in a homogeneous system or in the presence of a solubilized initiating/catalytic system. The present invention also concerns end-functional, site-specific functional and telechelic homopolymers and copolymers; block, random, graft, altenating and tapered (or "gradient") copolymers which may have certain properties or a certain novel structure; star, comb and "hyperbranched" polymers and copolymers; multi-functional hyperbranched, end-functional polymers; cross-linked polymers and gels; water-soluble polymers and hydrogels (e.g., a copolymer prepared by radical copolymerization of a water-soluble monomer and a divinyl monomer); and an ATRP process using water as a medium.

The ellipsoidal partial contour of the lamp bulb is produced by an elliptical section, the semiaxis of which is oriented vertically to the longitudinal axis, i.e. vertically to the rotational axis of the lamp bulb (10), and is longer than the greatest radius R of the lamp bulb. The length of the smallest semiaxis b lies preferably in the range R < b < R + 5 . w r, where R and w r respectively stand for the greatest radius of the lamp bulb (10) and the radius of the rotationally symmetrical luminous element (15). The lamp (9) is characterized by uniform back reflection of the I.R. radiation onto the luminous element (15) arranged centrically on-axis inside the lamp bulb (10), and thus by a regular temperature distribution, as well as by increased lamp efficiency.
