Patent CA-2229881-A1 (CA)
Title: Down hole mud circulation system
Inventor: HLAVINKA DANNY A
IPC: E21B21/10
Filed: 1998-02-18
Abstract: A down hole tool, constructed to be suspended in a well by pipe, includes a housing, a circulation piston, a biasing member and a pressure-compensation system.  The housing defines a flow chamber in open fluid communication with the pipe interior, a bypass port for fluid flow between the flow chamber and the well, a mud chamber in open communication with the well, and a sealed chamber separated from the flow chamber by a sealed interface.  The circulation piston separates the flow and mud chambers and is arranged for movement between a first, bypass port-blocking position and a second, bypass port-exposing position in response to pressure in the flow chamber.  The biasing member biases the circulation piston to its first position, and the pressure-compensation system limits the pressure difference between the flow and sealed chambers, thereby limiting the pressure difference across the sealed interface.  The tool has particular application to tools, e.g. well logging tools, adapted to be connected downhole to a wireline cable connector that is pumped down the well. Methods of use are also disclosed.
Patent CA-2230352-A1 (CA)
Title: Suspender attachment system
Inventor: LLOYD JOHN K L
IPC: A41F3/00
Filed: 1998-02-24
Abstract: A suspender system includes a pair of suspenders for holding work trousers. At the front end of each suspender strap is a patch of the hook component of a hook and loop fastener. A similar patch of hook component is found at the back end of each strap. The waistband of a pair of trousers has the mating loop component of the fastener stitched to its inside. The suspenders are therefore attached to the trousers without the use of conventional metal clips, which can damage surrounding objects which they contact and can damage and deform the trouser waistband.

Title: Method and apparatus for jogging and edging of mail and other flat articles
Inventor: MCKEE KENNETH A
IPC: B65H31/06
Filed: 1997-03-28
Abstract: The present invention relates to an apparatus and method for jogging and edging mail or other flat articles in preparation for feeding to a processing machine. Conventionally, when feeding articles into a sorting machine, an operator had to manually grab a bundle of mail to be sorted and manually shake the mail to align the bottom edges. The operator then placed the aligned stack against a feed member of the sorting machine. The present invention overcomes the inefficiency of manually shaking the flat articles by providing an automatic edging device. Specifically, the edging device (350) includes a plurality of generally spaced-apart upstanding fingers (355) which are forwardly translatable with a group of flat products between them. Each of the fingers is rockable back and forth across a vertical centerline as the fingers are forwardly translated to jostle the flat articles to align their bottom edges.

Abstract: A method for sticking a pellicle on an article to be protected, which comprises pressing a pellicle to the article with a pressure-sensitive adhesive having a hardness of 200 gf or below present between the open side of the pellicle frame and the article under a pressure equivalent to or exceeding the close adhesion pressure inherent in the pressure-sensitive adhesive to thereby make the pellicle adhere closely to the article; and pellicleprotected articles obtained by the method. A pellicle for ultraviolet rays of 140 to 200 nm in wavelength, provided with a pressure-sensitive adhesive and comprising a pellicle membrane, a pellicle frame for spreading and holding the membrane through an adhesive layer (a), and an adhesive layer (b) for fixing the frame on an article to be protected, wherein the generation from the layers (a) and (b) of compounds which are adsorbed or absorbed by the pellicle membrane and generate free radicals when irradiated with ultraviolet rays of 140 to 200 nm in wavelength is depressed to an amount of 200 ppm or below; and a case for the pellicles. Thus, the present invention provides a process for the production of an article (such as a mask, reticle or the like) which has a pellicle stuck thereon and is protected from the adhesion of dust thereon; a pellicle for ultraviolet rays of 200 nm or shorter in wavelength, provided with a pressure-sensitive adhesive and excellent in light resistance (endurance); and a case for the pellicles.

Title: A method for allowing a mobile phone to receive a call through a wireless network for which it is not registered, for emergency purposes
Inventor: KLEINDL GUNTER
IPC: H04W4/90
Filed: 1997-05-19
Abstract: A method for operating a wireless telephone system (110) to provide emergency service for a wireless telephone (101) operating in the wireless telephone system (110). In the present invention, the wireless telephone system (110) receives a request to connect the wireless phone (101) to a predetermined telephone number from the wireless telephone (101). The telephone system (110) then queries the wireless telephone (101) for a unique identifying number identifying the wireless telephone (101). The unique identifying number enables the wireless telephone system (110) to connect the wireless telephone (101) to the wireless telephone system (110). The wireless telephone system (110) maintains a set of direct inward dialing numbers (112) (DIDs) that are used exclusively for emergency calls. Each of the DID allows a caller outside of the wireless telephone system (110) to direct a call to a telephone within the wireless telephone system (110). The emergency call is assigned one of these DIDs and that DID is linked to the unique identifying number of the telephone placing the emergency call. The wireless telephone (101) is then connected to an emergency operator and the emergency operator (120) is given the assigned DID. The DID enables a call from the emergency operator to the wireless telephone (101) through the wireless telephone system (110). In one embodiment of the present invention, the DID assigned to the wireless telephone (101) also identifies the antenna (102-104) closest to the wireless telephone (101). The assignment between the DID and the unique identifying number is terminated after a predetermined period of time which may be altered by the caller or those servicing the emergency call.
