Inventor: CHOO THIAM HUAY GARY
IPC: B27N3/08
Filed: 2001-09-07
Abstract: The present invention relates to a moulding mixture, a moulding process and a mould for manufacturing moulded products. The process comprises the following steps: (a) preparing a moulding mixture by: (i) taking 40 to 60 wt% plant fibre pieces and optionally combining added starch with the plant fibre pieces; and (ii) adding thereto 10 to 55 wt% water and 3 to 10 wt% one or more water-soluble binding agents or adhesives; (b) pouring the mixture into a mould the mould being at a temperature of at least 60 ~C; (c) subjecting the mixture in the mould to a temperature in the range of 15 to 60 ~C and a pressure in the range from 1000 to 7000 PSI for a period of time such that a portion of the water in the mixture is converted to steam which causes the mixture to fill the mould while remaining in a mouldable state; (d) reducing the pressure so that steam continues to form within the mould without causing an explosion whilst maintaining the mixture in a mouldable state; (e) increasing the temperature and pressure to a temperature in the range from 100 to 200 ~C and a pressure in the range of 500 to 1500 PSI; (f) removing the steam or allowing the steam to escape until the moulded product is substantially dry; (g) removing the substantially dried and moulded product from the mould; The amount of starch added in between 0 and 10 wt preferably 0 to 2 wt% or 2 to 10wt%.

Filed: 2001-12-06
Abstract: A distribution device (1) stores a group of two or more digital contents and right management information (UR.Us) indicating a user's right range for the group in an interrelated manner. The distribution device transmits a digital content in the group to the NetDRM terminal device (2) together with an LT as requested by the user. Here, the distribution device updates the right management information to reduce the right range. When an updated LT is returned from the user, the distribution device increases the reduced right range based on a partial right range indicated by the updated LT. The distribution device again transmits an LT that indicates a partial right range of the increased right range and a different digital content in the group to the NetDRM terminal device (2) as requested by the user.
Patent CA-2431609-A1 (CA)
Inventor: MILLER DAVID
IPC: B29C70/30
Filed: 2002-01-08
Abstract: A method of preparing fiber preforms (18) disperses fibers and binder (14) on a forming support surface such that the materials are conditioned and then applied to the surface where the composite meterial solidifies. Reinforcing material, such as fiber, is mixed with binder, such as thermoplastic or thermoset materials, so that the materials adhere. Then, the adhesive mixture is dispersed in a controlled pre-determined weight ratio on the support surface where the mixture sticks to the support surface, cools and solidifies.  The deposited mixture can also be shaped further into a final desired shape before complete solidification. This process does not require a vacuum or plenum system to hold the reinforcing material in place. The preform can be made in any shape, including sections or asymmetric configurations.

Inventor: KUTA LEROY A
IPC: B65H19/10
Filed: 2002-06-04
Abstract: A method and apparatus for automatically applying a flying splicing tape to a roll of sheet material (22). The roll of sheet material is defined by a width and includes an outer-most layer. With this in mind, the method includes lifting a portion (170) of the outer-most layer away from a remainder of the roll. The lifted portion (170) is then cut to form a leading edge that is otherwise spaced from a remainder of the wound roll (22). To this end, the cut is made at a defined spacial location along the outer-most layer such that the leading edge is radially aligned with a defined application line (172) relative to a circumference on the wound portion of the roll. In other words, when the outer-most portion is subsequently wound back onto the roll, the leading edge will be aligned with the defined application line (172). The splicing tape (102) is then applied to the wound portion of the roll at the defined application line (172), such that the splicing tape extends across at least a portion of the width of the roll. In one preferred embodiment, the splicing tape is applied in a straight fashion relative to an axis of the roll. Finally, the leading edge is adhered to an outer surface of the splicing tape. More particularly, the leading edge is positioned relative to the splicing tape such that the outer-most layer covers a first section of the splicing tape, whereas a second section of the splicing tape remains exposed.  In another preferred embodiment, the applied splicing tape (102) is cut to form a trailing end that is substantially aligned with a side of the roll.

Title: Use of axial accelerometer for estimation of instantaneous rop downhole for lwd and wireline applications
Inventor: JOGI PUSHKAR N
IPC: E21B47/04
Filed: 2002-06-13
Abstract: Determination of the rate penetration (ROP) of drilling has usually been based upon surface measurements and may not be an accurate representation of the actual ROP. This can cause problems in Logging While Drilling (LWD). Because of the lack of a high-speed surface to-downhole communication while drilling, a conventional method of measuring ROP at the surface does not provide a solution to this problem. However, the instantaneous ROP can be derived downhole with a certain degree of accuracy by utilizing an accelerometer placed in (or near) the tool to measure acceleration in the axial direction.  When three-component accelerometers are used, the method may be used to determine the true vertical depth of the borehole.

Inventor: WOLFLI RICHARD J
IPC: G06F11/00
Filed: 2004-01-09
Abstract: The invention provides a new and novel method of backing up data, files and programs from a user's computers or servers to a remote backup service provider over the internet. The system proposed has a simple downloadable client program that is initially received from the backup service provider over the internet. The program automatically installs and runs without need for any configuration by the user. The program automatically scans the users machine for all files or data objects that require backing up based on it's internal programmed logic. It then compares this index with one provided by the backup server that contains the information as to what the client program has already backed up during previous backup sessions. The client program creates a merged list to only include the local data objects that have changed or are new on the user's computer. It then uploads in an optimized and encrypted fashion the identified data objects requiring backup to the backup server. The user's files, or more generically the data objects, are stored at the servers of the backup service provider in case the originals are lost from the user's computer or server.
