Abstract: Enhanced inserts are formed having a cylindrical grip and a protrusion extending from the grip. An ultra hard material layer is bonded on top of the protrusion. The inserts are mounted on a rock bit and contact the earth formations off center. The ultra hard material layer is thickest at a critical zone which encompasses a major portion of the region of contact between the insert and the earth formation. Transition layers may also be formed between the ultra hard material layer and the protrusion so as to reduce the residual stresses formed on the interface between the ultra hard material and the protrusion.

IPC: H04M3/38
Filed: 1999-03-10
Abstract: The present invention relates to a method for managing a subscriber's telecommunication service data stored in an exchange (EX1), as well as a server (SER) and an exchange (EX1) therefor. A data terminal (DT) of the subscriber sets up a connection to the exchange (EX1) via an online data network (ODN). The data terminal (DT) sends an access request from the subscriber to the exchange (EX1). The exchange (EX1) receives the access request. The exchange (EX1) and the data terminal (DT) interactively process the data, whereby the exchange (EX1) outputs the data to the data terminal (DT) and the data terminal (DT) sends the data to the exchange (EX1) at least if the data has been modified on the data terminal (DT). Finally, the exchange (EX1) stores the modified data, and the data terminal (DT) or the exchange (EX1) terminates the connection to the exchange (EX1) via the online data network (ODN).

Patent CA-2267546-A1 (CA)
Title: Tool cases with pivotable holders
Inventor: WEI YONG L
IPC: B25H3/02
Filed: 1999-03-30
Abstract: The case is generally upright, and has at least one item holder rotatably mounted therein, for rotation between a storage position and an access position. In the storage position, each holder is oriented parallel or close to parallel to the main plane of the case, to minimize space requirements. In the access position, each holder is oriented at an angle to the main plane of the case, such that the items angle outwardly from the case for easier access. Where two or more rotatable holders are used in the case, they preferably are ganged together, such that they rotate in unison. With the lid of the case open, or upon opening or removal of the lid, the item holders are able to rotate or be rotated to the access position. In some embodiments, they may rotate to the access position automatically upon opening of the lid, either by gravity or by virtue of a spring. In other embodiments, gravity may keep the holders in the storage position until they are manually moved to the access position, where they may then remain by gravity. In still other embodiments, the holders may be configured to rotate to the access position by gravity or by a spring, but may be prevented from doing so by a releasable catch or by a detent or the like. Once in the access position, the holders may be rotated back to their storage positions and retained there by gravity or a catch or detent or the like, or in some embodiments may only be returned and retained in their storage positions by closing the lid.

Title: Preparation of lucas reagent of enhanced utility and its use in synthesis of cycloaliphatic chlorides
Inventor: SENARATNE K PUSHPANANDA A
IPC: C01G9/04
Filed: 1999-10-25
Abstract: Gaseous anhydrous hydrogen chloride is introduced into an aqueous solution of zinc chloride under conditions effective to produce a more efficient Lucas reagent than a Lucas reagent made by mixing solid, anhydrous zinc chloride with 38 % hydrochloric acid. For example, the reaction rate of such Lucas reagent with levo-menthol is much faster and requires a much shorter reaction period than Lucas reagent formed in the conventional manner from anhydrous, solid zinc chloride and concentrated (38%) hydrochloric acid. Also, the conversion to levo-menthyl chloride was higher when using Lucas reagent formed using gaseous anhydrous hydrogen chloride and aqueous zinc chloride solution. Also, Lucas reagent made in this manner is highly amenable to recycling, and requires only addition thereto of hydrogen chloride to replenish the catalyst for an ensuing run.
