Abstract: This invention relates to a method for joining thermoplastic pipes (1) made by spiral winding a hollow profile (2) with mainly rectangular cross section. The method is characterized by the following stages: cutting the profile (2) in the end of the pipe along the inside of the side wall that is fastened to the nearest preceding wound round and with a cut (3) cutting the end of the profile in a right or obtuse angle (.alpha.), of equal size for all pipe ends to be joined together, closing the hole in the cut ends (3) of the profile, and preparing the end surfaces of the pipes along their entire peripheries; positioning two pipes (1) aligned to each other so that the cut profile ends (3) are axially offset; inserting a welding ring (5), matching with the inner and outer diameters of the pipes, between the two pipes (1); which welding ring comprises at least one loop of resistance of wire (8) covered by a thermoplastic sleeve (7); aligning the two pipes (1) with an inner root support (8) and an outer root support (9) around the seam with the welding ring (5); pressing the pipe ends together against each other connecting the resistance wire (6) of the welding ring to a current source (12) to heat the thermoplastic material in the welding ring (5) and in the pipe ends so that the thermoplastic material melts down and forms a welding seam, cooling the welding seam; removing the root supports (8, 9) and other accessories (10, 11) from the pipe welded together, and cutting off the connecting wires (13) of the welding ring.

Title: Tree brace
Inventor: ROY JAMES
IPC: A01G17/10
Filed: 2001-10-10
Abstract: A tree brace applies corrective forces to a part of a tree, such as the trunk, to straighten undesired bends or other deformities. A turnbuckle device applies force at a desired point of application, and is held by flexible lines that extend to locations above and below the application point. The turnbuckle is adjusted as the tree responds to the forces exerted thereon. The tree brace does not require a pole or stake for support, and can be placed on a tree wherever a bend or other deformity needs to be straightened.

Title: Medical drainage device with flow restriction feature
Inventor: RANFORD ALAN
IPC: A61M1/02
Filed: 2000-03-09
Abstract: The present invention provides for a dual port arrangement for a water seal chamber (17) of a drainage device (10) for channeling, and restricting fluid  flow through the water seal (22) during normal operation of the device (10) when the patient is breathing normally, while preventing the breach of the water seal (22) during reverse flow conditions when the patient takes a sudden, and deep inhalation. The dual port arrangement comprises a narrow si de port and an elongated tunnel port interposed between, and in communication with, both arms of the water seal chamber (20, 21). The side port has a thin  slot configuration that restricts fluid flow communication through the side port, and the back tunnel port defines a low profile, elongated conduit with  openings that channel fluid flow between both arms of the water seal chamber . The elongated configuration of the conduit also prevents a steep water gradient from falling below the upper portion of the conduit opening during reverse flow conditions, and breach the water seal.

Title: Efficient and secure bill payment via mobile ip terminals
Inventor: O'NEIL JOSEPH
IPC: G06Q20/32
Filed: 2001-11-15
Abstract: An efficient and secure system and method for customers with mobile terminals to pay bills for services rendered at a merchant's establishment. In an exemplary embodiment, the merchant's establishment is a restaurant. The restaurant has a server which uses short-range wireless technology to answer inquiries from customers. The server also stores charges for each table, which are transmitted to and displayed on a customer's mobile terminal when the customer requests a bill. A network-based server receives approval from the mobile terminal to charge the user's credit card number for services rendered by the merchant. The charges are then forwarded to, and validated by, an appropriate credit card agency server. The network-based server provides both the merchant and the user with payment confirmations. Payment information, however, such as a credit card number, is not revealed to the merchant, thereby eliminating the possibility of unauthorized use by an unscrupulous merchant or agent thereof.

Title: Removal of dental caries with high speed water jet
Inventor: TURDIU PARID
IPC: A61C5/00
Filed: 2000-03-17
Abstract: A method and device for the high speed fluid (preferably water) jet removal of dental caries. The water jet is of a controlled upper and lower speed and pressure with a low speed and pressure being of at least 5 to 10 kpsi, sufficient to pierce and flush decayed tissue of a caries with a small beam fluid jet diameter. A pulsed or continuous fluid jet is used to remove and completely flush caries material from a tooth in a time period of under a second with a maximum stagnation pressure of about 30 kpsi, at which point healthy dentin is affected. A coherent or pseudo-coherent water jet operatin g at high stagnation pressure (range 10,000 to 20,000 psi and no more than 30 kpsi), in a brief burst (~ 1 second) and small beam diameter (30 to 100 .mu. m) will cleanly remove caries without damage to the tooth structure in particul ar the sound dentin at the boundary of the caries. No anaesthetic is accordignl y required in the abscence of a possible exposed nerve.
